FeedWordPress is an Atom/RSS aggregator for WordPress. It syndicates content
from feeds that you choose into your WordPress weblog; the content it syndicates
appears as a series of special posts in your WordPress posts database. If you
syndicate several feeds then you can use WordPress's posts database and
templating engine as the back-end of an aggregation ("planet") website. It was
developed, originally, because I needed a more flexible replacement for
[Planet][] to use at [Feminist Blogs][].
[Planet]: http://www.planetplanet.org/
[Feminist Blogs]: http://feministblogs.org/
FeedWordPress is designed with flexibility, ease of use, and ease of
configuration in mind. You'll need a working installation of WordPress or
WordPress MU (version [3.0] or later), and also FTP or SFTP access to your web
host. The ability to create cron jobs on your web host is helpful but not
required. You *don't* need to tweak any plain-text configuration files and you
*don't* need shell access to your web host to make it work. (Although, I should
point out, web hosts that *don't* offer shell access are *bad web hosts*.)
[WordPress]: http://wordpress.org/
[WordPress MU]: http://mu.wordpress.org/
[3.0]: http://codex.wordpress.org/Version_3.0
== Installation ==
To use FeedWordPress, you will need:
* an installed and configured copy of [WordPress][] or [WordPress MU][]
(version 3.0 or later).
* FTP, SFTP or shell access to your web host
= New Installations =
1. Download the FeedWordPress installation package and extract the files on
your computer.
2. Create a new directory named `feedwordpress` in the `wp-content/plugins`
directory of your WordPress installation. Use an FTP or SFTP client to
upload the contents of your FeedWordPress archive to the new directory
that you just created on your web host.
3. Log in to the WordPress Dashboard and activate the FeedWordPress plugin.
4. Once the plugin is activated, a new **Syndication** section should
appear in your WordPress admin menu. Click here to add new syndicated
feeds, set up configuration options, and determine how FeedWordPress
will check for updates. For help, see the [FeedWordPress Quick Start][]
page.

= Upgrades =
To *upgrade* an existing installation of FeedWordPress to the most recent
release:
1. Download the FeedWordPress installation package and extract the files on
your computer.
2. Upload the new PHP files to `wp-content/plugins/feedwordpress`,
overwriting any existing FeedWordPress files that are there.
3. Log in to your WordPress administrative interface immediately in order
to see whether there are any further tasks that you need to perform
to complete the upgrade.
4. Enjoy your newer and hotter installation of FeedWordPress
== Using and Customizing FeedWordPress ==
FeedWordPress has many options which can be accessed through the WordPress
Dashboard, and a lot of functionality accessible programmatically through
WordPress templates or plugins. For further documentation of the ins and
outs, see the documentation at the [FeedWordPress project homepage][].

== Changelog ==
= 2012.1218 =
* WORDPRESS VISUAL EDITOR FIXED. There was an unlisted change in the
2012.1212 release which had the effect of disabling the WordPress Visual
Editor for all posts syndicated by FeedWordPress. Many users reported
this as a bug. It was actually a deliberate decision -- a crappy way to
try to deal with a crappy situation. (Many users had previously reported
a "bug" in which all the paragraph or line breaks seemed to be stripped
out of their syndicated posts; the issue turned out to be that the
Visual Editor was stripping out `<p>` and `<br/>` tags on the assumption
that the resulting post would be sent through standard WordPress
formatting filters. But under default settings, posts syndicated by FWP
deliberately bypass WordPress formatting filters.) In any case, this
version adopts a more flexible compromise. *If* FeedWordPress is set up
to bypass WordPress formatting filters (as it is by default), *then*
the Visual Editor will be disabled for syndicated posts (since using it
would produce incorrect results). If on the other hand FeedWordPress is
set up to expose syndicated posts to WordPress formatting filters (as it
usually is for those using the Visual Editor to manually edit posts),
then the Visual Editor tab will be re-enabled for syndicated posts.
* BUG FIX: PERMALINKS REWRITTEN FOR CUSTOM POST TYPES AS WELL AS NORMAL
WORDPRESS POSTS. If you had WordPress set up to syndicate incoming posts
to a custom post type (under Syndication > Posts & Links), and asked
FeedWordPress to make "permalinks point to the original site", then
previous versions of FeedWordPress would fail to do the rewriting --
permalinks would only be rewritten to point to the original source for
normal WordPress posts, not for custom post types. In 2012.1218 this bug
has been fixed: all post types will now have permalinks rewritten unless
you request for permalinks to point to the local copy on your aggregator
site.
* BUG FIX: ELIMINATES "PHP Fatal error: Call to a member function
setting() on a non-object...." Some changes to the in-memory caching of
information about feed subscriptions could result in a fatal PHP error
in cases where you have de-activated one of your subscriptions, but
posts from that subscription were still in the archive. This would
normally show up through half-completed feeds or half-completed pages
that suddenly broke off in the middle, and displayed or logged an error
message like: "PHP Fatal error: Call to a member function setting() on a
non-object in {...}/wp-content/plugins/feedwordpress/feedwordpress.php
on line 615". This bug has been eliminated, so affected feeds and pages
should now render correctly, and the error message should no longer
appear.
* BUG FIX: CATEGORY BOXES IN SYNDICATION > CATEGORIES & TAGS. Some minor
bugs in the appearance and animation of category checkboxes (for
example, the checkbox used to select categories for syndicated posts on
the Syndication > Categories & Tags settings page) have been fixed.
= 2012.1212 =
* WORDPRESS 3.5 COMPATIBILITY: This release has been tested for compatibility
with new releases of WordPress, up to version 3.5, and any documented
compatibility issues have been cleared -- in particular, if you were seeing
error pages stating that you don't have permission to access the
FeedWordPress Syndication page within the WordPress admin interface, then
upgrading to this release should fix the problem.
As always, if you encounter any compatibility problems after upgrading your
version of WordPress and your version of FeedWordPress to the most recent
versions, please contact me with as detailed a description as possible of
the issue you are encountering, the circumstances you're encountering it
under, what you expect to see happening, and what is happening instead.
* PHP 5.4 COMPATIBILITY: This release has been audited to fix potential
problems with deprecation notices or fatal errors under recent versions
of PHP. In particular, all uses of run-time pass-by-reference have been
eliminated from the code; if you were seeing a fatal error reading
"Call-time pass-by-reference has been removed ..." then upgrading to
this release should fix the problem.
* CUSTOMIZATION FRAMEWORK: A great deal of work has been done to make the
underlying framework more flexible, so that PHP add-ons can be written
to adapt FeedWordPress to handle custom XML vocabularies, expiration of
posts under specified conditions, and other custom behavior.
* BUGFIX: MANUALLY EDITED POST SLUGS NOT OVERWRITTEN. Thanks to a report
by Chris Fritz, I've identified some code that causes post slugs for the
posts generated by FWP to be rewritten with every update, even if the
user has manually updated the slug from within the WordPress editing
interface. This has been fixed: FWP will continue to generate new slugs
for syndicated posts, but when syndicated posts are updated, they will
retain the slug that they had at the time of the update; any manual
changes to the post slug should be preserved.
* USER-AGENT STRING: FeedWordPress now sends a distinctive User-Agent
string identifying itself, and noting that it is a feed aggregator.
* MISCELLANEOUS PERFORMANCE IMPROVEMENTS: A number of changes have been
made to try to reduce the intensity and expense in terms of both
database performance and web server memory consumption.
* DIAGNOSTICS IMPROVEMENTS: A number of new and improved diagnostics have
been added which should aid in understanding and troubleshooting issues
that may arise.
= 2011.1019 =
* BUGFIX: "THERE ARE NO HTTP TRANSPORTS AVAILABLE" ERROR FIXED: The initial
support for HTTP Basic and Digest authentication in version 2011.1018
contained a bug that could cause HTTP requests for feeds or for other
WordPress resources to break down if you do not have the PHP curl module
installed. This bug has been fixed, and these errors should no longer
appear.
* IMPROVED HTTP AUTHENTICATION SUPPORT: In addition, the HTTP Authentication
support in FeedWordPress has been extended, to ensure that Basic
authentication is available in many web host configurations, and to allow
you to add a username and password for a feed immediately when you
subscribe to it.
= 2011.1018 =
* HTTP BASIC AND DIGEST AUTHENTICATION SUPPORT: FeedWordPress now offers
improved support for syndicating feeds that make use of HTTP Basic or HTTP
Digest authentication methods. In order to set up authentication on one of
your feeds, just go to its Settings > Feed page, and click on the "Uses
Username/Password" link underneath the Feed URL. Enter the username and
password for accessing the feed, then select the authentication method. (If
you're not sure which method your feed provider uses, try Basic first.)
Save Changes, and syndicate away.
NOTE: HTTP Digest support requires the curl module for PHP. If you are not
sure whether this module has been installed, contact your web hosting
provider to check.
* WP 3.3 (BETA) COMPATIBILITY: This version fixes an init-sequence bug that
could cause intrusive warning messages or fatal errors in WP 3.3 beta
versions.
* BUGFIX: FIXES LONG DELAYS IN UPDATES SCHEDULES IN LARGE INSTALLATIONS. A
performance feature introduced in version 2011.0721 had some flaws in its
implementation, which tended to create serious delays (on the order of
several hours) in FeedWordPress's attempts to schedule updates for feeds,
when users had a very large number of feeds (several dozen or more) in their
FeedWordPress installation. This feature has been reconfigured to adjust
dynamically to the number of feeds in Syndicated Sources and the frequency
with which they are updated. If you've seen a lot of ready-to-update feeds
piling up, several hours after they were supposed to get updated, then this
upgrade should better ensure that your feeds get updated in a timely fashion.
* BUGFIX: syndicated_item_guid FILTERS FIXED. Previous versions of
FeedWordPress theoretically allowed for filters on the syndicated_item_guid
hook, which was intended to filter the globally-unique identifier element
(rss:guid or atom:id) -- useful if you need to convince FeedWordPress to use
different guids, or to recognize two or more incoming posts as versions of
the same post rather than as distinct items. However, while the hook
affected the guid stored in the WordPress database, it did not affect the
guid used to check whether an incoming feed item had already been syndicated
or was a new item -- which greatly limited the practical usefulness of the
filter. This bug has been fixed: syndicated_item_guid filters should now
properly control not only the final database record, but also the initial
uniqueness test applied to posts.
= 2011.0721 =
* BUGFIX: SERIOUS BUG CAUSING RARE UNEXPECTED DELETION OF PAGES AND OTHER
CONTENT. A bug in the guid-checking code for some rare kinds of guids could
cause content in the wp_posts table to seemingly disappear at random after
FeedWordPress updates.This most frequently but not exclusively affected
static pages. What actually happened is that in these rare cases the
existing static page was mistaken for an older version of the new incoming
syndicated post, which was then stored as a new revision of the original
page. The bug that caused these mistaken identities has been fixed.
* BUGFIX: UNWANTED AUTOMATIC PAGE-LOAD-BASED UPDATES NO LONGER A NUISANCE.
Some users encountered a bug in which FeedWordPress would adopt an automatic
page-load-based update method, even if they had requested that it not do
so, and that it use a manual or cron job update method instead. The bug
causing this has been fixed, and page-load-based updates should no longer
trigger unless explicitly turned on.
* WP 3.2 USER INTERFACE COMPATIBILITY: POST TAGS BOX NOW WORKS AGAIN. The
release of WordPress 3.2 caused a breakage in the tags box which prevented
you from adding or removing tags under Syndication --> Categories & Tags.
(The breakage was the result of an incompatibility introduced by the new
release of jQuery.) This breakage has now been fixed, and the tags box
should work correctly again.
* FEED UPDATE SCHEDULING IMPROVEMENTS: UI. The Syndicated Sources table now
provides considerably more data to understand update scheduling, when
specific scheduling decisions are made because of, e.g., requests from the
feed producer.
* FEED UPDATE SCHEDULING IMPROVEMENTS: ENFORCEABLE "MINIMUM INTERVAL" SETTING
TO SPACE OUT UPDATES. Some feeds request specific update schedules, using
standard elements such as sy:updateFrequency and rss:ttl. Normally,
FeedWordPress respects any scheduling requests that a feed makes -- if it
requests a longer gap between polls than what FWP would normally adopt, then
FWP slows down to meet the request. If it indicates a shorter gap than what
FWP would normally adopt, FWP speeds up and checks that feed for updates
more often than it normally would. Now, there should not be any way for user
settings to override an explicit slow-down request from the feed producer --
if producers indicate a particular update schedule, then polling the feed
more frequently than they request is considered abusive behavior. But
there's no reason why users should not be able -- if they so desire -- to
override speed-up requests, and poll a feed *less* frequently than the
indicated update schedule, if the FWP user wants to space update checkins
over a longer interval of time. Before, they could not do this: FWP always
sped up to meet the indicated update schedule. Now, they can do this, by
using the new "Minimum Interval" setting in Syndication --> Feeds &
Updates..
= 2011.0706 =
* WP 3.2 COMPATIBILITY: ELIMINATES FATAL ERROR "Call to undefined method
WP_SimplePie_File::WP_SimplePie_File() in
[...]/wp-content/plugins/feedwordpress/feedwordpress.php on line 1841." The
latest release of WordPress, version 3.2, has shifted the minimum
requirements up to PHP 5.2, and in line with the shift to PHP5 they have
rewritten a number of code segments that made use of now-obsolete PHP4
idioms. Unfortunately, this caused a fatal error whenever FeedWordPress
attempted to make use of the cache, since FWP's caching plugin was written
to match the older idiom. FeedWordPress has been updated to follow the new,
PHP5 idiom when possible, thus eliminating the fatal error.
* PERFORMANCE: The handling of queries to determine whether posts had been
previously syndicated produced some very slow queries (usually, but not
always, involving a scan over the MD5(post_guid) column of the table). The
code that prepares MySQL queries for previously-syndicated checks has been
revised to eliminate the MD5(post_guid) scan entirely, and to significantly
improve performance by eliminating other unnecessary clauses.
* BUGFIX: NO LONGER DESTROYS STICKY POSTS. Previous versions could destroy
(or, more precisely, replace the content of) sticky posts due to some
queries mashed together in unexpected ways by WordPress. Version 2011.0706
accounts for and eliminates the problem; your sticky posts should be safe
once again.
* BUGFIX: GUIDS CONTAINING MYSQL-ESCAPED CHARACTERS NO LONGER CAUSE DUPLICATE
POSTS TO APPEAR. One remaining source of duplicate post issues in 2011.0602
was guids that contained characters that needed to be escaped for MySQL,
such as single quotes and double quotes. The work-around for handling
filtered URIs has now been corrected to ensure that these do not cause
duplicate posts.
= 2011.0602 =
* WP 3.1.3 COMPAT / BUGFIX: WHITESPACE IN GUIDS NO LONGER PRODUCES DUPLICATE
POSTS. The work-around for handling filtered URIs in guid elements has now
been extended to handle URIs that were filtered because of leading or
trailing whitespace, in addition to URIs that were filtered because of
unapproved schemes.
* WP 3.1.3 COMPAT / BUGFIX: RELATIVE URLS IN GUIDS NO LONGER PRODUCE DUPLICATE
POSTS. The work-around for handling filtered URIs in guid elements has now
been extended to handle URIs that were altered without being filtered out
entirely (most commonly because a scheme was added to a relative URL).
* BUGFIX: UPDATES TO POST NO LONGER CAUSE DUPLICATE DRAFT VERSION TO APPEAR.
Under certain conditions in 2011.0531, an update to an existing post would
not be properly applied to the post itself, but rather would appear as a
duplicate post with Draft status. This bug has been eliminated, and updates
will now be properly inserted as revisions to the existing post.
= 2011.0531 =
* WORDPRESS 3.1.3 COMPATIBILITY: DUPLICATE POSTS ISSUE FIXED. Due to
internal changes in the way that WordPress handles post guids in the
most recent release (3.1.3), many users experienced problems with many
duplicate posts appearing in rapid succession. (Specifically, this would
happen with any posts using tag: URL guids -- such as all the posts
coming from Blogger feeds or feeds from other Google services.) This
compatibility release of FeedWordPress eliminates the issue by working
around the new restrictions on tag: URLs.
* NEW AND IMPROVED DIAGNOSTICS: Syndication --> Diagnostics now contains some
new diagnostics settings useful for debugging problems with duplicate posts
(allowing you to easily view the guid of posts in the WordPress posts
database and allowing you to track the SQL used to check for existing
versions of a syndicated post).
= 2011.0512 =
* DIAGNOSTICS IMPROVEMENTS; "THERE MAY BE A BUG IN FEEDWORDPRESS" CRITICAL
ERROR NOTICES ELIMINATED: This version includes some major improvements
to the Syndication --> Diagnostics section, which should aid in
troubleshooting difficulties with items failing to be imported, posts
failing to be properly inserted into the database, or updates failing to
be recorded. If you have been encountering critical error / bug notices
with a white screen and the message "THERE MAY BE A BUG IN
FEEDWORDPRESS," followed by an extraordinarily long dump of mostly
incomprehensible diagnostic information, you'll be happy to know that
the condition causing these notices has been eliminated. In the few
cases where errors may still crop up with database insertions,
FeedWordPress will now produce a significantly more manageable and more
useful diagnostic message.
* BUGFIX: NEW POSTS FAILING TO APPEAR IN A CLEANLY-INSTALLED FEEDWORDPRESS
SYSTEM. If you encountered a recurring problem with FeedWordPress
failing to import new posts, after a clean install of FeedWordPress
(i.e., not an upgrade from a previous version), this problem may have
been the result of a bug with author-handling which has now been fixed
in the 2011.0512 release. (If the problem does *not* go away with the
upgrade, this version also includes significant improvements to the
Diagnostics system, which will help track down what *is* causing it
in your particular case.)
* PERFORMANCE: New handling of update hashes allows FeedWordPress to avoid
a certain kind of infinite loop, caused when two more more different
syndicated feeds each carried a version of the same item (for example,
because it appeared on two different aggregator feeds that you're
syndicating). In previous versions, when this kind of loop cropped up,
syndicated posts could pile up an indefinitely large number of revisions
-- each revision alternating between the version from each of the two
feeds where it appeared -- which would, over time, dramatically inflate
the size of the database, and kill the performance of queries on the
post table. This issue has been resolved: revisions of the post that
have been syndicated once will not be re-syndicated over and over again.
* AUTHOR LISTS: Lists of authors presented on the Author settings pages
should now be easier to scan through, with author names arranged in
alphabetical order.
* FEED ITEM DATE PARSING: More tweaks to make date-time handling more
resilient when feeds provide broken or weird values for the timestamps
on syndicated items. FWP will now attempt to work around unparseable
timezone values.
* AUTHOR MATCHING: Now attempts to match author names against the WP login
name in addition to display_name; when creating user record, also fills
in some best-guess values for nickname, firstname and lastname. Also
properly picks up Atom 1.0 author/uri data from feed.
* COMPATIBILITY: FeedWordPress has been successfully tested for
compatibility with recent releases of WordPress, up to version 3.1.2.
= 2011.0211 =
* BUGFIX: DUPLICATE POSTS WHEN GUIDS ARE TOO LONG: When feeds included
exceptionally long GUIDs, FeedWordPress could occasionally get into
a situation where posts with the long GUIDs would be duplicated over
and over again with each update (because FWP failed to store the full
GUID, due to length constraints in the relevant database tables).
Without the full GUID, FWP would not know that the post had already
been syndicated once. This bug has been fixed, and should no longer
produce duplicate posts.
* HTTP TIMEOUT SETTING: If you are frequently running into timeout
problems with one or more of the feeds you syndicate, FWP now allows you
to adjust the timeout for HTTP requests using a global or feed-by-feed
setting.
* HTTP GET PARAMETERS: You can now temporarily or permanently add HTTP
GET parameters to a subscription using an interface in Syndication -->
Feeds & Updates. This is especially helpful for making quick, short-term
changes to a subscription (for example, to pull in all the previous
items from a web service, before settling down to pulling in only newly
updated items).
* DIAGNOSTICS SYSTEM: Added several new diagnostics which are useful in
troubleshooting, and established a framework for add-on modules to hook
in with their own diagnostic messages.
* UI: Adjusted some internal coding, which should allow for settings
pages and add-ons to properly display multiple category pickers on a
single settings page.
* PHP4 COMPATIBILITY TWEAKS: This version makes some tweaks to the handling
of object references which should improve compatibility with older
versions of PHP. (Although, I should note, web hosts that still force
you to run under PHP 4 -- in 2011! -- are *bad web hosts*.)
* IMPROVED PERFORMANCE: This version eliminates a *major* performance drag
that shows up on sites with large numbers of users (due to some poor
decisions about where to place a user query, which caused the user table
to be scanned frequently when it did not need to be). If you experienced
serious problems with CPU load or slow database performance under
2010.0905, which kicked in immediately when FWP was loaded and tended
to disappear immediately if FWP was de-activated, it is likely that
upgrading away from 2010.0905 to the most recent version will resolve
your problem.
= 2010.0905 =
* BUGFIX: CATEGORIES AND TAGS CORRECTLY ASSIGNED IN AUTOMATIC UPDATES.
Version 2010.0903 switched over to a new way of assigning categories and
tags as part of its support for handling custom taxonomies.
Unfortunately, the method that it uses is subjected to some checks of
the current user's capabilities, which creates problems for posts that
are being inserted into the WordPress database when there *is* no
current user logged in (as, for example, when an update is being carried
out from a cron job or automatic update). The result was that posts
from cron jobs and automatic updates ended up with no Categories and no
Tags being assigned. This bug has now been fixed: in 2010.0905, Tags and
Categories should be correctly assigned to all posts, regardless of
whether they were added from manual updates, cron jobs, or automatic
updates.
= 2010.0903 =
* WORDPRESS 3 REQUIRED: Please note that this release of FeedWordPress
*requires* WordPress 3.0 or later. If you are currently using a 2.x
branch of WordPress, you will need to upgrade to WordPress 3 before you
can successfully upgrade FeedWordPress.
* BUGFIX: NO MORE DISAPPEARING "SYNDICATED SOURCES" PANEL; INTERNET
EXPLORER UI GLITCH APPARENTLY FIXED: Several users independently
reported a problem with FWP 2010.0623 and various versions of IE. A
problem with the HTML markup caused IE (but not Firefox or
Chrome) to completely hide the Syndicated Sources administration panel
(the main list of currently-syndicated sources, and the main location
for adding new sources, under the Syndication menu item) when a user
added their first syndicated feed. Maddeningly, the glitch seemed to
affect some IE users and not others: I was never able to reproduce the
problem for myself on my own machines. However, the markup of Syndicated
Sources has undergone significant changes and corrections since
2010.0623, and two independent sources who had been having this problem
confirm that they no longer encounter it with the updated version. For
the time being, I am going to declare this bug squashed.
* BUGFIX: MORE PROTECTION AGAINST FATAL ERRORS FROM PLUGGABLE VERSIONS OF
SimplePie: FeedWordPress now takes some precautions that should help to
better avoid conflicts for users who have installed pluggable versions
of SimplePie for another plugin or theme. (You may not know that you have
done this; but if you've been encountering fatal errors indicating that
you cannot redeclare class SimplePie, or something along those lines,
there is now a better chance that those fatal errors will be eliminated.
* PERFORMANCE: SIGNIFICANTLY REDUCED MEMORY CONSUMPTION FOR LARGE UPDATES:
FeedWordPress is still a memory-hungry little module, especially when
you are dealing with very large feeds. However, users should notice a
significant reduction in memory overloads, especially if they update a
large number of feeds at once.
* USER INTERFACE IMPROVEMENTS: Nothing is radically different, but there's
been a fair amount of extra spit and polish added, including a convenient
new Dashboard widget that may save you a trip to the Syndication menu,
a lot of effort to make the relationship between global and feed-by-feed
settings more obvious to the user and more easily controllable, to make
navigation between settings pages easier, to sand off a few rough edges,
and to make other improvements on the margins. I hope you'll like how
it looks.
* ADDING MULTIPLE FEEDS: FeedWordPress now provides a convenient mode for
adding multiple feeds at once, using either a copy-and-pasted list, or
else an OPML file. Go to Syndication --> Syndicated Sources and check
out the two new buttons underneath the New Source input box. When you
have to add a number of feeds at once, this can save you considerable
time and trouble.
* IMPROVED HANDLING OF AUTHORS WITH DUPLICATE E-MAIL ADDRESS AND AUTHORS
WITH NAMES WRITTEN IN FOREIGN SCRIPTS: WordPress 3 is increasingly picky
about what it will accept for new author accounts, and some of the
conditions it imposes can cause error conditions that prevent posts from
being properly syndicated, or properly attributed, if authors happen to
have identical e-mail addresses, or if users are given usernames that are
written in non-Western scripts. FeedWordPress now handles these much
better, and systematically works to avoid clashes between syndicated
authors' account names or in their e-mail addresses, which should result
in significantly better results in mapping author names to WordPress
user accounts.
* MAPPING CATEGORIES ON SYNDICATED POSTS TO TAGS NOW BETTER SUPPORTED:
In previous versions, the only way for the Categories provided by a
syndicated feed to be mapped into Post Tags was to instruct FWP to
create new tags, rather than new categories, for unfamiliar categories
from the feed. This works fine if you want tags to be the default; but
if you want only a *specific* set of tags, there was no way to get them
without getting most or all other categories imported as tags. You can
now do this by creating a tag (under Posts ==> Post Tags) before
importing the post; when the syndicated category matches a pre-existing
tag, the incoming post will be tagged with that tag, without creating
a local Post Category.
* REL-TAG MICROFORMAT SUPPORT FOR INLINE TAGS: Syndicated posts that
contain inline tags, marked up using the Rel-Tag microformat
<http://microformats.org/wiki/rel-tag>, are now tagged with the tags
provided by Rel-Tag format links.
* MUCH GREATER CONTROL OVER CATEGORY AND TAG MAPPING: This is partly the
result of building in support for a potentially endless set of custom
taxonomies (see below), but in general there has been a great deal of
effort towards giving you more control over how categories and tags
provided by the feed are mapped into terms on the local blog. In
particular, you can now force FeedWordPress to create only categories
from categories and tags provided by the feed; or to create only tags;
or to search both categories and tags for a match; or you can simply
force it to drop all of the categories provided by the feed and use
only categories or tags that you explicitly provide. In addition, you
can now also choose whether to override global categories settings with
a local, feed-specific setting; or whether to *add together* *both* the
global categories and the local feed-specific categories -- depending
on whatever your use-case may demand.
* CUSTOM POST TYPES AND TAXONOMY SUPPORTS: This is mainly for the
super-geeky, but if you use other plugins or themes that make
significant use of WordPress's support for custom post types and custom
taxonomies, you may be pleased to find that FeedWordPress now allows you
to feed incoming posts into any custom feed type that you wish, and to
map categories and tags from the feed to custom taxonomies as well as
to the standard Category and Tag taxonomies.
* STORING NAMESPACED CUSTOM FEED ELEMENTS IN POST CUSTOM FIELDS: If you
would like to use FeedWordPress's support for storing custom meta-data
from feed elements in the custom fields for a post (for example, to
store geolocation data or iTunes media meta-data), you'll find that it's
now much easier for you to access these namespaced elements. You always
could access them, but in previous versions you might have to write
something ugly like $(/{http://www.w3.org/2003/01/geo/wgs84_pos#}lat)
just to get at the value of a `<geo:lat>` tag. Now, as long as you use
the same mnemonic codes that the feed producer used, you should always
be able to write a nice, simple expression like $(/geo:lat) to get the
value of a <geo:lat> tag.
* CUSTOM DIRECTORY STRUCTURE SUPPORT: if you poke at it enough, WordPress
is relatively flexible about where it should store admin interface code,
uploaded content, plugins, and a number of other things that occupy an
important place in the WordPress directory structure. Previous versions
of FeedWordPress encountered serious errors or broke entirely when used
with directory structures other than the default. This should now be
fixed: FWP now supports custom directory structures wherever WordPress
allows them to be customized, rather than depending on the default
locations. Enjoy your freedom!
* MANY NEW FILTERS AND API UTILITY FUNCTIONS FOR ADD-ON PROGRAMMERS: There
have been too many improvements to list them all in this ChangeLog, but
it means that much more power and ease for folks who are customizing
FeedWordPress through PHP filters or add-on modules. Fuller
documentation will be put up at the Wiki at feedwordpress.radgeek.org
soon.
= 2010.0623 =
* WORDPRESS 3.0 COMPATIBILITY / AUTHOR MAPPING INTERFACE ISSUES: I
resolved a couple of outstanding issues with the author mapping
interface (Syndication --> Authors), which were preventing new users
from being created correctly and author mapping rules from being set up
correctly. These partly had to do with new restrictions on user account
creation introduced in WordPress 3.0; anyway, they should now be fixed.
* MORE EFFICIENT SYNDICATED URL LOOKUPS: Several users noticed that the
bug fix introduced in 2010.0528 for compatibility with post-listing
plugins caused a lot more queries to the database in order to look up
numerical post IDs from the URL provided to the filter. This shouldn't
cause any major problems, but it is not as efficient as it could be; the
code now takes advantage of a more efficient way of doing things,
which usually will not require any additional database queries.
* SIMPLEPIE FEED UPDATE ISSUES: If you have been having significant
problems with getting feeds to update correctly, this may be the result
of some bugs in the implementation of SimplePie caching that ships with
WordPress (as of version 3.0). (You would most commonly experience this
error if you continually saw errors such as "No feed found at <...>" in
your updates.) Fortunately, SimplePie allows for a great deal of
extensibility and this allows me to work around the problem; these
error conditions should now be mostly eliminated when the underlying
feed is valid.
* UI: SHOW INACTIVE SOURCES: When you use the default unsubscribe option
-- which turns off the subscription to a feed while preserving the posts
from it and the syndication-related meta-data for the feed -- the
unsubscribed feed can now easily be viewed in a special "Inactive"
section of the Syndicated Sources page. (As a side benefit, if you've
accidentally, or only temporarily, turned off the subscription to a
feed, it is now much easier to restore the feed to being active, or to
delete it permanently, if you prefer.
* UI: FEED FINDER / SWITCH FEED INTERFACE IMPROVEMENTS: changes to styling
and options for the feed finder / switch feed, which should now make it
easier, in some cases, to find alternative feeds, and make interface
options more clearly visible.
* FILTERS: `syndicated_item_published` and `syndicated_item_updated` NOW
PROPERLY AFFECT THE DATING OF POSTS. These filters used to affect some
date-related settings, but not others -- and, most importantly, not the
final date that is set for a post's publication or last-modified date
in the WordPress database. Now, they do affect that, as they should.
(Filters should receive, and return, a long integer, representing a Unix
epoch relative timestamp.)
* MAGIC URL TO CLEAR THE CACHE: Suppose that you need to clear the feed
cache, for whatever reason; suppose, even, that you need to clear it on
a regular basis. One way you might do this is by logging into the
FeedWordPress administrative interface and going to Syndication -->
Performance. Another way you might do it, now, is to simply send an
HTTP request to a magic URL provided by FeedWordPress: if your blog is
at example.com, the URL would be <http://example.com/?clear_cache=1>
= 2010.0602 =
* CATEGORY BOX INTERFACE ELEMENT FIXED FOR WP 3.0: Stylesheet changes
between WordPress 2.9.x and the WordPress 3.0 RC caused the Categories
box under **Syndication --> Categories & Tags** to malfunction. This
has been fixed.
* LINK CATEGORY SELECTION BOX IN SYNDICATION ==> FEEDS FIXED FOR WP 2.8
AND 2.9: A WP 3.0 compatibility change introduced in 2010.0531
inadvertently broke the Syndicated Link Category selector under
Syndication --> Feeds & Updates in WP 2.8 and WP 2.9, causing the post
categories to be displayed in the selector rather than the link
categories. This should now be fixed so that the selector will work
correctly under both the current versions of WordPress and the 3.0 RC.
* MORE PERMISSIVE HANDLING OF FEEDS WITH BAD CONTENT-TYPE HEADERS: One of
the small advantages that MagpieRSS had over SimplePie is that it was
more tolerant about parsing well-formed feeds that the remote web server
happened to deliver with weird or incorrect HTTP Content-type headers.
In feeds affected by this problem, the new SimplePie parser would simply
fail to find a feed, due to its being led astray by the contents of the
Content-type header. This version includes an extension to SimplePie's
content-type sniffer that offers more permissive handling of the HTTP
headers.
* MORE FULL-TEXT "EXCERPTS" NOW PROPERLY SHORTENED. Version 2010.0528
introduced code to control for cases in which elements intended for
item summaries are (ill-advisedly) used to carry the full text of posts;
past versions of FeedWordPress would simply include the full text of the
post in the excerpt field, but newer versions now attempt to detect
this condition when it arises and to head it off, by blanking out the
excerpt field and filling it with an automatically generated short,
plain text excerpt from the full content. This release broadens the
test conditions that indicate when an excerpt field is treated as
identical to the full text of the post, and should therefore improve
the handling of some feeds (such as Google Reader feeds) where the full
text of each post was still appearing in the excerpt field.
* FILTERS: `syndicated_item_published` AND `syndicated_item_updated`
FILTERS NOW ALLOW FILTER AUTHORS TO CHANGE POST TIMESTAMPS. You can now
use the `syndicated_item_published` and `syndicated_item_updated` filter
hooks to write filters or add-ons which directly change the post date
and most-recently-updated timestamps on incoming syndicated posts. Props
to niska for pointing out where the filters needed to be applied in
order to change WordPress's internal timestamps for incoming posts.
= 2010.0531 =
* PERMALINK / CUSTOM FIELDS PROBLEM RESOLVED: An issue in 2010.0528 caused
some posts to be imported without the proper syndication-related
meta-data being attached (thus causing permalinks to point back to the
aggregator website rather than to the source website, among other
problems). This problem has been resolved (and a fix has been applied
which will resolve the problem for any posts affected by this problem,
if the original post is recent enough to still be available on the feed).
* UI: The "Back End" section has been split into two separate sections --
"Performance" (dealing with caching, database index, and other
performance tweaks), and "Diagnostics" (dealing with debug mode,
update logging, and a number of new diagnostic tests which I will be
rolling out over the next few releases).
* Several minor interface bug fixes and PHP warning notices eliminated.
= 2010.0528 =
#### Compatibility ####
* SIMPLEPIE IS NOW USED TO PARSE FEEDS; NO MORE MAGPIERSS UPGRADES NEEDED:
One of the biggest changes in this release is that FeedWordPress no
longer depends on MagpieRSS to parse feeds, and has switched to the much
more up-to-date and flexible SimplePie feed parser, which is included as
a standard part of WordPress versions 2.8 and later. Using SimplePie will
hopefully allow for better handling of feeds going further, and will
allow me greater flexibility in determining how exactly the feed parser
will operate. It also means that FeedWordPress no longer requires
special upgrades to the WordPress core MagpieRSS files, and should
eliminate quite a bit of complexity.
* MAGPIERSS COMPATIBILITY LAYER FOR EXISTING FILTERS AND ADD-ONS: However,
I have also implemented a compatibility layer to ensure that existing
filters and add-ons for FeedWordPress which depended on the MagpieRSS
data format *should not be broken* by the switch to SimplePie. Going
forward, I recommend that new filters and add-ons be written to take
advantage of the SimplePie object representations of items, feeds, etc.,
rather than the MagpieRSS arrays, but the MagpieRSS arrays will still
be available and older filters should continue to work as they have in
the past.
* COMPATIBILITY WITH WORDPRESS 2.9.x and 3.0: This release has been tested
for the existing WordPress 2.9.x branch and with the upcoming release of
WordPress 3.0. Changes in the user interface JavaScript between WordPress
2.8.x and WordPress 2.9 caused the tag box interface element to break in
the Syndication --> Categories & Tags settings page; changes in the API
functions for adding new authors caused fatal errors under certain
conditions in WordPress 3.0. These breakages have been fixed.
* DROPPED LEGACY SUPPORT FOR WORDPRESS PRIOR TO 2.8: Because SimplePie is
not included with versions of WordPress prior to 2.8, I have chosen to
drop legacy support for WordPress versions 1.5 through 2.7. If you are
using FeedWordPress with a version of WordPress before 2.8, you will
have to upgrade your installation of WordPress in order to take
advantage of this release.
* PHP 5.3 COMPATIBILITY: A couple of compatibility issues, which were
causing fatal errors amd ugly warnings for users of PHP 5.3,
have been eliminated.
#### Features and Processing ####
* INTERFACE REORGANIZATION: The interface restructuring, began with
Version 2009.0612, has been completed. Catch-all settings pages have
been eliminated entirely for pages that cover each aspect of handling
a feed: Feeds & Updates, Posts & Links, Authors, Categories & Tags,
and Back End handling of the database and diagnostic information.
Extensive new interface hooks allow add-on modules to significantly
change or extend the FeedWordPress admin interface and workflow.
* STORING INFORMATION FROM THE FEED IN CUSTOM FIELDS: Many users
have written to request the ability to store information from elements
in the feed in a custom field on each post. (So that, for example, if
post includes a `itunes:duration` element, you could store the contents
in a Custom Field called `duration` on the post (for a Theme to access
later). The Custom Post Settings under Syndication --> Posts & Links now
allow you to access any item or feed tag, using a syntax similar to
a much-simplified version of XPath. See Posts & Links settings for
details.
* UPDATE-FREEZING ON MANUALLY EDITED POSTS: FeedWordPress now allows you
to mark posts that have been manually edited, so that the changes you
make will not be overwritten by later updates from the feed. If you make
manual edits to a particular post, just check the "Manual editing"
checkbox in order to protect your changes from being overwritten. If you
want to block *all* posts from being updated after they are imported
for the first time, a new "Updated Posts" setting in Posts & Links
allows you to freeze all posts from a particular feed, or all syndicated
posts.
* SETTING: FEED-BY-FEED SETTINGS FOR WHERE PERMALINKS POINT TO: You've
always been able to tell FeedWordPress whether permalinks for posts
should point to the original source of the story or the local copy. Now
you can choose different policies for different feeds, instead of one
global policy for all feeds. (Of course, you can still use a global
default if you prefer.)
* SETTING: USER CONTROL OVER TIMING BASIS. You can now determine the
schedule on which feeds are considered ready to poll for updates --
by default feeds become ready for polling after about 1 hour. You can
now increase or decrease the time window under Syndication --> Feeds &
Updates. (However, please pay *CAREFUL ATTENTION* to the recommendations
and DO NOT set the scheduling lower than 60 minutes unless you are
ABSOLUTELY SURE that you have specific permission from webmaster who
provides that specific feed to poll more frequently than that. If you
set this too low (and about 60 minutes is the polite minimum if you
haven't been given a different figure), most webmasters will consider
the frequent hits on their server as rude, or even downright abusive.
* OTHER SETTINGS: New settings also include the ability to stop FWP from
resolving relative URLs within syndicated content, and the ability to
choose whether FeedWordPress should indicate the comment feed from the
original source, or the local comment feed, when providing the comment
feed URL for a syndicated post.
#### Parsing ####
* BETTER DATE HANDLING -- FEWER FLASHBACKS TO 1969 and 1970: FeedWordPress
has made some bugfixes and some improvements in the logic for parsing
dates. This should allow FeedWordPress to correctly parse more dates in
more feeds; and, in the last resort, when FeedWordPress fails to
correctly parse a date, to fall back to a more intelligent default. This
should hopefully avoid most or all error conditions that have resulted
in articles being erroneously dated to the dawn of the Unix epoch
(31 December 1969 or 1 January 1970).
* FULL-TEXT "EXCERPTS" NOW PROPERLY SHORTENED. Based on a straightforward
reading of the existing RSS specs, it's reasonable for the
rss:description element to be read as a plaintext summary or excerpt for
the item containing the description -- with the full text of the item,
if available, in another, better-suited element, such as the de facto
standard content:encoded extension element. The problem is that uses of
RSS rarely have much to do with anything like a straightforward reading
of the specs. As a result, many actual RSS producers in the wild put the
full text of the article in a description element. But since
FeedWordPress has treated this text as a summary, this produces
aggregated posts with lengthy "excerpts" containing the full text of the
article. This release of FeedWordPress fixes the problem by doing a
little digging before treating rss:description as a summary: if the
description element is used properly as a plain text summary, then
FeedWordPress will take the summary provided by the feed, rather than
recreating its own excerpt from the full text; but if an RSS item has no
full-text element other than description, FeedWordPress will treat the
description element as the full text of the article, and generate a
shortened excerpt automatically from that text.
#### API ####
* TEMPLATE API: new template tags `get_local_permalink()` and
`the_local_permalink()` allow you to access the permalink for a post on
your aggregator site, even when FeedWordPress is rewriting permalinks to
point to the original source site.
* NEW HOOKS FOR ADD-ONS AND FILTERS: I have added a number of new hooks
which allow add-on modules to filter more precisely, gather information
at more points, and to enhance the FeedWordPress admin interface. For
a list of new hooks and documentation, see the FeedWordPress
documentation wiki at
<http://feedwordpress.radgeek.com/wiki/add-ons-and-filters>
* FILTER API: A number of new utility methods have been added to the
SyndicatedPost class to make it easier for filters and add-ons to
* FILTER API: Globals $fwp_channel and $fwp_feedmeta DEPRECATED. These
global variables, originally introduced to allow filters access to
information about the source feed in `syndicated_item` filters (which
were passed in through global variables rather than as parameters
because of a bug in WP 1.5 which was then fixed in 1.5.1) have been
DEPRECATED. If you have any filters or add-ons which still depend on
these global variables, you should see about fixing them to access data
about the source feed using the SyndicatedPost::link element instead.
For documentation, see the FeedWordPress documentation wiki at
<http://feedwordpress.radgeek.com/wiki/syndicatedpost> and
<http://feedwordpress.radgeek.com/wiki/syndicatedlink>.
* DIAGNOSTICS: I've included a number of new diagnostic options and
messages, which should allow an experienced user to better investigate
any problems that may crop up.
#### Bug Fixes ####
* BUGFIX: & IN PERMALINKS NO LONGER CAUSING ATOM OR HTML VALIDATION
EFFORTS: Many users reported an issue in which syndicating a feed with
special XML characters in the URLs (& was the most common, since it is
used to separate HTTP GET parameters) would cause the aggregator's
feeds to produce invalid (malformed) XML. This update addresses the
issue in Atom feeds. Unfortunately, it has not been technically possible
to address the problem in RSS 2.0 feeds, due to limitations on
WordPress's internal templates for RSS feeds.
* BUGFIX: BROKEN URLS IN "POPULAR POSTS" AND SIMILAR PLUGINS SHOULD NO
LONGER BE BROKEN. A number of users noticed an issue where plugins and
templates that listed posts in locations outside of the post loop
(for example, "Popular Posts"-style plugins that listed posts in the
sidebar), often produced the wrong URL for post links. (Typically, all
the posts listed would get the same wrong URL.) This should now be
fixed. Thanks to Björn for sending in a quick fix!
* MINOR BUGFIXES: This release includes a number of fixes to minor bugs
and compatibility issues, including: silent failures of the "Syndicate"
button, "Illegal Offset Type" error messages from MagpieRSS, and others.
= 2009.0707 =
* BUGFIX: WORDPRESS 2.8 AJAX COMPATIBILITY ISSUES RESOLVED (blank or
truncated "Syndicated Sites" administration page): Due to changes in the
AJAX interface elements between WordPress 2.7 and WordPress 2.8, several
FeedWordPress users encountered an issue where the front "Syndication"
page in the FeedWordPress administrative interface would come up blank,
without the normal "Syndicated Sites" list and "Update" control, or
sometimes wth the boxes visible but one or both of them truncated, with
only the title bar. This issue should now be resolved: with the new
version of FeedWordPress, the compatibility issue that caused the
disappearance should be eliminated, and if boxes are shown with only
their handle visible, you should once again be able to drop down the
rest of the box by clicking once on its title bar.
* BUGFIX: TAG SETTING WIDGET FIXED. Due to changes in interface elements
between WordPress 2.7 and WordPress 2.8, people using FeedWordPress with
WordPress 2.8 found that the widget for setting tags to be applied to
all syndicated posts, or all syndicated posts from a particular feed,
no longer displayed "Add" and "Remove" buttons for individual tags. This
issue has now been fixed, and the tagging widget should once again work
more or less exactly like the tagging widget for individual posts in the
normal WordPress admin interface.
= 2009.0618 =
* BUGFIX: MYSTERY ERRORS WITH WITH WP_Http_Fsockopen HTTP TRANSPORT
ELIMINATED: Thanks to a combination of a subtle bug in FeedWordPress,
and changes to the HTTP transport code in WordPress, a number of users
encountered an error in which any time they attempted to add a new feed
through the FeedFinder interface, FeedWordPress would fail and display
an HTTP request failure diagnostic message. The subtle bug has been
fixed, and with it, most of these errors should now be eliminated.
Be sure to upgrade your MagpieRSS to the most recent MagpieRSS version
after you have insalled FeedWordPress 2009.0618, or this bug fix will
not take effect.
= 2009.0613 =
* INTERFACE/BUGFIX: WORDPRESS 2.8 CATEGORY BOX FIX. Thanks to a subtle
change in class names between the WordPress 2.7 and 2.8 stylesheets,
category boxes in the FeedWordPress settings interface tended to overflow
and have a lot of messy-looking overlapping text under WordPress 2.8.
This has now been fixed.
* FeedFinder FAILURE DIAGNOSTICS: When FWP's FeedFinder fails to find any
feeds at a given URL (for example, when you are trying to add a
subscription through the administrative interface and you run into an
error message), FeedWordPress now provides more diagnostic information
for the reasons behind the failure. If that helps you, great; if not,
it should help me respond more intelligently to your support request..
= 2009.0612 =
* WORDPRESS 2.8 COMPATIBILITY: FeedWordPress 2009.0612 has been tested for
compatibility with the recent version 2.8 release of WordPress.
* INTERFACE RESTRUCTURING: In order to avoid settings posts from becoming
too crowded, and to modularize and better organize the user interface,
new "Posts" and "Categories & Tags" subpages have been created under the
"Syndication" menu. "Posts" controls settings for individal syndicated
posts (such as publication status, comment and ping status, whether or
not to use the original location of the post as the permalink, whether
or not to expose posts to formatting filters, and so on). "Categories &
Tags" controls settings for assigning new syndicated posts to categories
and tags, such as categories or tags to apply to all syndicated posts,
and how to handle categories that do not yet exist in the WordPress
database. These subpages, like the Authors subpage, handle settings for
the global default level and for individual syndicated feeds.
Corresponding to these new subpages, the old Syndication Settings and
Feed Settings subpages have been cleaned up and simplified, and now only
link to the appropriate subpages for options that can be set in the
Posts, Authors, or Categories & Tags subpages.
* FEATURE: ADD CUSTOM SETTINGS TO EACH SYNDICATED POST: FeedWordPress has
long had an interface for creating custom settings for each syndicated
*feed* which could be retrieved in templates using the `get_feed_meta()`
template function. But it had no feature for adding custom fields to
each individual syndicated *post*. In response to requests from users, I
have added the ability to apply custom fields to each individual
syndicated post, using the new Syndication --> Posts subpage. You can
set up custom fields to be applied to every syndicated post, or custom
fields to be applied to syndicated posts from a particular feed.
* FEATURE: MAGPIERSS VERSION CHECK AND UPGRADE: FeedWordPress will attempt
to determine whether or not you are using the upgraded version of
MagpieRSS that comes packaged with FeedWordPress. If not, it will throw
an error on admin pages, and, if you are a site administrator, it will
give you the option to ignore the error message, or to attempt an
automatic upgrade (using a native file copy). If the file copy fails,
FeedWordPress will offer some guidance on how to perform the upgrade
manually.
* BLANK POSTS PROBLEM NO LONGER OCCURS WITH OLD & BUSTED MAGPIERSS: Due
to the fact that I relied on a content normalization that occurs in my
upgraded version of MagpieRSS, but not in the old & busted version of
MagpieRSS that ships with WordPress, until this version, if you tried to
syndicate an Atom feed without having performed the (*strongly
recommended*) MagpieRSS upgrade, all of the posts would come up with
completely blank contents. That's not because MagpieRSS couldn't read
the data, but rather because the new Magpie version puts that data in a
location where the old version doesn't, and I was only looking in that
newer location. Now it checks for both, meaning that posts will continue
to display their contents even if you don't upgrade MagpieRSS. (But you
**really should** upgrade it, anyway.)
* BUGFIX: RELATIVE URI RESOLUTION FOR POST CONTENT RESTORED. Some time
back, I added support for resolving relative URIs against xml:base on
feeds that support it to the MagpieRSS upgrade in FeedWordPress. Then I
took out code that did the same thing from the main FeedWordPress code.
Of course, the problem is that some people, even though it is clearly
stupid or evil to do so, still include relative URIs for images or links
in posts on feed formats that do *not* adequately support xml:base
(notably, RSS 2.0 feeds). In response to a user request, I have added
this functionality back in, so that MagpieRSS will resolve any relative
URIs that it knows how to resolve using xml:base, and then FeedWordPress
will attempt to resolve any relative URIs that are left over afterwards.
* BUGFIX: INTERFACE OPTION FOR SETTING SYNDICATED POST PUBLICATION STATUS
ON A FEED-BY-FEED BASIS HAS BEEN RESTORED: Due to a version-checking
bug, users of WordPress 2.7.x lost an option from the "Edit a syndicated
feed" interface which allowed them to determine whether newly syndicated
posts should be published immediately, held as "Pending Review," saved
as drafts, or saved as private posts. (The option to change this
setting globally remained in place, but users could no longer set it on
a feed-by-feed basis.) The version-checking bug has been fixed, and the
option has been restored.
* BUGFIX: "ARE YOU SURE?" FATAL ERROR ELIMINATED AND SECURITY IMPROVED:
Under certain circumstances (for example, when users have configured
their browser or proxy not to send HTTP Referer headers, for privacy or
other reasons), many features in the FeedWordPress administrative
interface (such as adding new feeds or changing settings) would hit a
fatal error, displaying only a cryptic message reading "Are you sure?"
and a blank page following it. This problem has been eliminated by
taking advantage of WordPress's nonce functions, which allow the
security check which ran into this error to work properly even without
receiving an HTTP Referer header. (N.B.: WordPress's nonce functions
were first introduced in WordPress 2.0.3. If you're using FeedWordPress
with an older version of WordPress, there's no fix for this problem:
you'll just need to turn Referer headers back on. Sorry.)
* BUGFIX: MANUALLY-ALTERED POST STATUS, COMMENT STATUS, AND PING STATUS NO
LONGER REVERTED BY POST UPDATES: If you manually altered the post status,
comment status, or ping status of a syndicated post from what it was set
to when first syndicated -- for example, if you had a feed that was set
to bring in new posts as "Pending Review," and you then marked some of
the pending posts as "Published" and others as "Unpublished" -- then
in previous versions of FeedWordPress, these manual changes to the
status would be lost -- so that, for example, your Published or Unpublished
articles would revert to Pending Review -- if the source feed made any
upates to the item. This could make the Pending Review feature both
unreliable and also extremely frustrating to work with. The good news is
that this bug has since been fixed: if you manually update the status
of a post, it will no longer be reverted if or when the post is updated.
* BUGFIX: OCCASIONAL FATAL ERROR ON UPDATE ELIMINATED: Under certain
limited conditions (specifically, when both the title and the content of
a post to be updated are empty), an attempt to update the post would
result in a fatal error. This has been fixed.
* INTERFACE: "CONFIGURE SETTINGS" CONVENIENCE LINK ADDED TO CONFIRMATION
MESSAGE WHEN A NEW FEED IS ADDED: When you add a new subscription to
FeedWordPress, the message box that appears to confirm it now includes a
handy link to the feed's settings subpage, so that you can quickly set
up any special settings you may want to set up for the new feed, without
having to hunt through the list of all your other subscriptions to pick
out the new one.
* INTERFACE: SIMPLIFYING AND CLARIFYING AUTOMATIC UPDATES SETTINGS. I have
removed an interval setting for the cronless automatic updates which has
confused many FeedWordPress users. In past versions of FWP, when you
turned on automatic updates, you would be presented with a time interval
setting which controlled how often FeedWordPress would check for feeds
ready to be polled for updates. (That is, it DID NOT control how often
feeds *would be polled*; it controlled how often FeedWordPress would
*check* for feeds that *had become ready to poll*. The schedule on which
feeds became ready for polling was still controlled either by requests
encoded in elements within the feed itself, or else according to an
internal calculation within FeedWordPress, averaging out to about 1 hour,
if the feed did not include any scheduling request elements.) Since many
users very often (and understandably) confused the purpose of this
setting, and since the setting is for a feature that's actually very
unlikely to require any manual control by the user, I have removed the
setting; FeedWordPress now simply uses the default value of checking for
feeds to poll every 10 minutes.
* FEEDFINDER PERFORMANCE IMPROVEMENT: FeedWordPress's FeedFinder class
now uses `array_unique()` to make sure that it doesn't waste time
repeatedly iterating over and polling the same URI. Props to Camilo
(<http://projects.radgeek.com/2008/12/14/feedwordpress-20081214/#comment-20090122160414>).
= 2008.1214 =
* WORDPRESS 2.7 COMPATIBILITY: FeedWordPress has been tested for
compatibility with the newly released WordPress 2.7. WordPress 2.7 has
deprecated the Snoopy library for HTTP requests, which caused a fatal
error for users who had not installed the MagpieRSS upgrade (or whose
installation of the MagpieRSS upgrade was overwritten by a recent update
of WordPress). FeedWordPress now handles things gracefully when Snoopy
is not immediately available.
* INTERFACE SPIFFED UP: Interface elements have been updated so that
FeedWordPress's management interface fits in more naturally with the
WordPress 2.7 interface (including a new logo and a number of small
interface tweaks).
* BUG WITH TAGS FOR SYNDICATED ARTICLES FIXED: Several users encountered a
bug with the option to add tags to all syndicated posts under
Syndication --> Settings -- if you told FeedWordPress to add more than
one tag to all syndicated posts, instead of doing so correctly, it would
add a *single* tag instead, whose name was composed of the names of all
the tags you asked it to add. This bug was the result of nothing more
dignified than a typographical error on my part. It has now been fixed.
* MORE INFORMATION AVAILABLE WHEN FEEDWORDPRESS CAN'T FIND A FEED: When
you enter a URL for a new syndication source, FeedWordPress uses a
simple feed-finding algorithm (originally based on Mark Pilgrim's
Universal Feed Finder) to try to determine whether the URL is the URL
for a feed, or, if the URL points to an ordinary website rather than to
a feed, whether there is a feed for that website. All well and good, but
if FeedWordPress failed to find a feed, for whatever reason, it would
typically return nothing more than a nasty little note to the effect of
"no feed found," without any explanation of what went wrong.
FeedWordPress now keeps track of error conditions from the HTTP
requests that it uses in the course of looking for the feed, and so may
be able to give you a bit more information about the nature of the
problem if something goes wrong.
= 2008.1105 =
* INTERFACE RESTRUCTURING AND SYNDICATION --> AUTHORS PAGE: As a first
step towards modularizing and better organizing the user interface, a
new "Authors" subpage has been created under the Syndication menu, which
controls settings for syndicated authors, both at the global default
level and at level of individual syndicated feeds.
* BUG RELATED TO THE ATTRIBUTION OF POSTS TO THE WRONG AUTHOR FIXED: Some
users encountered an issue in which posts by different authors on
different blogs -- especially blogs generated by Blogger -- were
mistakenly attributed to a single author. The problem was caused by the
way in which FeedWordPress matches syndicated authors to user accounts
in the WordPress database: normally, if two feeds each list an author
with the same e-mail address, they are counted as being the same person.
Normally this works well, but it creates an issue in cases where
blogging software assigns a single anonymous e-mail address to users who
do not want their real e-mail address published. This is, for example,
what Blogger does (by giving all users a default e-mail address of
<noreply@blogger.com> if they don't want their own e-mail address
listed). FeedWordPress now allows the user to correct for this problem
with a couple of new settings under **Syndication --> Authors**, which
allow users to turn off e-mail based author matching for particular
addresses, or, if desired, to turn it off entirely. By default, e-mail
based author matching is still turned on, but disabled for a list of
known generic e-mail addresses. Right now, the "list" consists entirely
of <noreply@blogger.com>; if you know other addresses that should be
added, please [contact me](http://radgeek.com/contact) to let me know.
Please note that if you have already encountered this issue on your
blog, upgrading FeedWordPress will prevent it from re-occurring in the
future, but you still need to do two other things to fix the existing
problem on your blog.
First, for each feed where posts have been mis-attributed, you need to
change the existing author mapping rules to re-map a a syndicated
author's name to the proper target account. Go to **Syndication -->
Authors**, select the feed you want to change from the drop-down list,
and then change the settings under the "Syndicated Authors" section.
(You will probably need to select "will be assigned to a new user..." to
create a new user account with the appropriate name.)
Second, for each feed where posts have been mis-attributed, you need to
re-assign already-syndicated posts that were mis-attributed to the
correct author. You can do that from **Syndication --> Authors** by
using the author re-assignment feature, described below.
* AUTHOR RE-ASSIGNMENT FOR A PARTICULAR FEED: The author settings page
for each syndicated feed, under **Syndication --> Authors**, now
includes an section titled "Fixing mis-matched authors," which provides
an interface for re-assigning or deleting all posts attributed to a
particular author on a particular feed.
* SUPPORT FOR `<atom:source>` ELEMENT IN SYNDICATED FEEDS: Some feeds
(for example, those produced by FeedWordPress) aggregate content from
several different sources, and include information about the original
source of the post in an `<atom:source>` element. A new setting under
**Syndication --> Options** allows you to control what FeedWordPress
will report as the source of posts syndicated from aggregator feeds in
your templates and feeds: you can have FeedWordPress report that the
source of a post is the aggregator feed itself, or you can have it
report that the source of a post is the original source that the
aggregator originally syndicated the post from.
By default, FeedWordPress will report the aggregator, not the original
source, as the source of a syndicated item.
* LOAD BALANCING AND TIME LIMITING FEATURES FOR UPDATES: Some users have
encountered issues due to running up against PHP execution time limits
during the process of updating large syndicated feeds, or a very large
set of syndicated feeds. FeedWordPress now has a feature that allows you
to limit the total amount of time spent updating a feed, through the
"Time limit on updates" setting under **Syndication --> Options**. By
turning on this setting and adjusting the time limit to a low enough
figure to avoid your PHP installation's time-out setting. (PHP execution
time limits are usually in the vicinity of 30 seconds, so an update
time limit of 25 seconds or so should provide plenty of time for updates
while allowing a cushion of time for other, non-update-related functions
to do their work.)
If feed updates are interrupted by the time limit, FeedWordPress uses
some simple load balancing features to make sure that updates to other
feeds will not be blocked by the time-hogging feed, and will also make
sure that when the interrupted update is resumed, FeedWordPress will
skip ahead to resume processing items at the point at which it was
interrupted last time, so that posts further down in the feed will
eventually get processed, and not get blocked by the amount of time it
takes to process the items higher up in the feed.
* `guid` INDEX CREATION BUTTON: FeedWordPress frequently issues queries on
the `guid` column of the WordPress posts database (since it uses post
guid URIs to keep track of which posts it has syndicated). In very large
FeedWordPress installations, you can often significantly improve
performance by creating a database index on the `guid` column, but
normally you would need to poke around with MySQL or a tool like
phpMyAdmin to do this. FeedWordPress can now save you the trouble: to
create an index on the `guid` column, just go to
**Syndication --> Options**, and mash the button at the bottom of the
"Back End" section.
= 2008.1101 =
* INTERFACE BUG THAT PREVENTED ADDING NEW SITES FIXED: The UI reforms in
FWP 2008.1030 unintentionally introduced a bug that prevents clean
installations of FeedWordPress from providing an input box for adding
new feeds to the list of syndicated feeds. This bug has been fixed.
= 2008.1030 =
* WORDPRESS 2.6 COMPATIBILITY: FeedWordPress should now be compatible with
WordPress 2.6, and should work more or less seamlessly with the new post
revision system. A bug which caused multiple new revisions to be created
for posts on certain feeds, regardless of whether or not the item had
been updated, has been fixed.
* INTERFACE IMPROVEMENTS: The user interface has been substantially
restyled to fit in better with the visual style of WordPress 2.5 and
2.6.
* YOUTUBE BUG FIXED: POSTS SYNDICATED THROUGH AN AUTOMATIC UPDATE ARE NO
LONGER STRIPPED OF `<OBJECT>` TAGS AND CERTAIN OTHER HTML ELEMENTS: Due
to the way that some versions of WordPress process posts that are
inserted into the database when no user is logged in, many users
experienced an issue where YouTube videos and other content using the
HTML `<object>` tag would be stripped out of posts that were syndicated
during an automatic update. (Posts that were syndicated through manual
updates from within the WordPress Dashboard were not affected, because
the issue does not arise when an update is executed under a logged-in
administrator's credentials.) This bug has now been fixed; YouTube
videos and other content using `<object>` tags should now appear
properly in syndicated posts, regardless of the way in which the post
was syndicated.
* AJAX BUGS FIXED: Bugs which blocked the normal operation of WordPress
2.5's AJAX interface elements when FeedWordPress was activated have been
fixed.
* TAG SUPPORT: A couple of features have been introduced to take advantage
of the tagging features in WordPress 2.3.x, 2.5.x, and 2.6.x. Now, when
unfamiliar categories are encountered for posts on a feed, you can
choose for FeedWordPress (1) to drop the category; (2) to drop the
category and to filter out any post that does not match at least one
familiar category; (3) to create a new category with that name, or,
now, you can also have FeedWordPress (4) create a new *tag* with that
name. This option can be set site-wide under Syndication --> Options,
or it can be set on a feed-by-feed basis in a feed's Edit screen.
In addition, you can now set particular tags to apply to all incoming
syndicated posts, under Syndication --> Options, or you can set tags
to apply to all incoming syndicated posts from a particular feed in that
feed's Edit screen.
* FORMATTING FILTERS: There is a new option available under Syndication ->
Options which allows users to choose whether or not to expose syndicated
posts to being altered by formatting filters. By default, FeedWordPress
has always protected syndicated posts (which are already in display-ready
HTML when they are syndicated) from being reformatted by formatting
filters. However, this approach means that certain plugins which depend
on formatting filters (for example, to add "Share This" bars or relevant
links to the end of a post) are blocked from working on any syndicated
posts. If you want to use one of these plugins together with
FeedWordPress, you can now do so by changing the "Formatting Filters"
setting from "Protect" to "Expose."
* `<atom:source>` ELEMENTS NOW INCLUDED IN ATOM FEED: Atom 1.0 provides
a standard method for aggregators to indicate information about the original source of
a syndicated post, using the `<atom:source>` element. FeedWordPress now
introduces standard `<atom:source>` elements including the title, homepage, and
feed URI of the source from which a syndicated post was syndicated. Cf.
<http://www.atomenabled.org/developers/syndication/atom-format-spec.php#element.source>
* MODULARIZATION OF CODE: The code for different elements of FeedWordPress
has been broken out into several modules for easier inspection,
documentation, and maintenance of the code.
* VERSIONING SCHEME CHANGED: FeedWordPress's feature set has proven stable
enough that it can now be removed from beta status; a good thing, since
I was very quickly running out of version numbers to use. New releases
of FeedWordPress will have version numbers based on the date of their
release.
= 0.993 =
* WORDPRESS 2.5.1 COMPATIBILITY: FeedWordPress should now be compatible
with WordPress 2.5.1.
* WORDPRESS 2.5 INTERFACE IMPROVEMENTS: FeedWordPress's Dashboard
interface has undergone several cosmetic changes that should help it
integrate better with the WordPress Dashboard interface in WordPress
version 2.5.x.
* SYNDICATED POSTS CAN BE MARKED AS "PENDING REVIEW": WordPress 2.3 users
can now take advantage of WordPress's new "Pending Review" features for
incoming syndicated posts. Posts marked as "Pending Review" are not
published immediately, but are marked as ready to be reviewed by an
Administrator or Editor, who can then choose to publish the post or
hold it back. If you want to review syndicated posts from a particular
feed, or from all feeds, before they are posted, then use
Syndication --> Syndicated Sites --> Edit or Syndication --> Options to
change the settings for handling new posts.
* AWARE OF NEW URI FOR del.icio.us FEEDS: Previous releases of
FeedWordPress already automatically split del.icio.us tags up
appropriately appropriately when generating categories. (del.icio.us
feeds smoosh all the tags into a single `<dc:subject>` element,
separated by spaces; FeedWordPress un-smooshes them into multiple
categories by separating them at whitespace.) Unfortunately, del.icio.us
recently broke the existing behavior by changing host names for their
feeds from del.icio.us to feeds.delicious.com. Version 0.993 accounts
for the new host name and un-breaks the tag splitting.
= 0.992 =
* AUTHOR RE-MAPPING: FeedWordPress now offers considerable control over
how author names on a feed are translated into usernames within the
WordPress database. When a post by an unrecognized author comes in,
Administrators can now specify any username as the default username to
assign the post to by setting the option in Syndication --> Options
(formerly FeedWordPress only allowed you to assign such posts to user
#1, the site administrator). Administrators can also create re-mapping
rules for particular feeds (under Syndication --> Syndicated Sites -->
Edit), so that (for example) any posts attributed to "Administrator"
on the feed <http://praxeology.net/blog/feed/> will be assigned to
a user named "Roderick T. Long," rather than a user named
"Administrator." These settings also allow administrators to filter out
posts by particular users, and to control what will happen when
FeedWordPress encounters a post by an unrecognized user on that
particular feed.
* BUG RELATED TO URIS CONTAINING AMPERSAND CHARACTERS FIXED: A bug in
WordPress 2.x's handling of URIs in Blogroll links created problems for
updating any feeds whose URIs included an ampersand character, such as
Google News RSS feeds and other feeds that have multiple parameters
passed through HTTP GET. If you experienced this bug, the most likely
effect was that FeedWordPress simply would not import new posts from a
feed when instructred to do so, returning a "0 new posts" response. In
other cases, it might lead to unpredictable results from feed updates,
such as importing posts which were not contained in the feed being
syndicated, but which did appear elsewhere on the same website. This bug
has, hopefully, been resolved, by correcting for the bug in WordPress.
= 0.991 =
* WORDPRESS MU COMPATIBILITY: FeedWordPress should now be compatible with
recent releases of WordPress MU. Once FeedWordPress is made available
as a plugin, each individual blog can choose to activate FeedWordPress
and syndicate content from its own set of contributors.
* DISPLAY OF MAGPIE WARNINGS: A number of MagpieRSS warnings or error
messages that were displayed when performing an automatic update are
no longer displayed, unless debugging parameters have been explicitly
enabled.
* BUG RELATED TO INTERNATIONAL CHARACTERS IN AUTHOR NAMES FIXED: Due to a
subtle incompatability between the way that FeedWordPress generated new
user information, and the way that WordPress 2.0 and later added new
authors to the database, FeedWordPress might end up creating duplicate
authors, or throwing a critical error message, when it encountered
authors whose names included international characters. This
incompatability has now been fixed; hopefully, authors with
international characters in their names should now be handled properly.
* `<media:content>` BUG IN MAGPIERSS FIXED: A bug in MagpieRSS's handling
of namespaced elements has been fixed. Among other things, this bug
caused items containing a Yahoo MediaRSS `<media:content>` element (such
as many of the feeds produced by wordpress.com) to be represented
incorrectly, with only a capital "A" where the content of the post
should have been. Feeds containing `<media:content>` elements should now
be syndicated correctly.
* update_feedwordpress PARAMETER: You can now use an HTTP GET parameter
(`update_feedwordpress=1`) to request that FeedWordPress poll its feeds
for updates. When used together with a crontab or other means of
scheduling tasks, this means that you can keep your blog automatically
updated on a regular schedule, even if you do not choose to use the
cron-less automatic updates option.
* Some minor interface-related bugs were also fixed.
= 0.99 =
Version 0.99 adds several significant new features, fixes some bugs, and
provides compatability with WordPress 2.2.x and 2.3.x.
* WORDPRESS 2.2 AND 2.3 COMPATIBILITY: FeedWordPress should now be
compatible with WordPress version 2.2 and the upcoming WordPress
version 2.3. In particular, it has been tested extensively against
WordPress 2.2.3 and WordPress 2.3 Release Candidate 1.
* AUTOMATIC UPDATES WITHOUT CRON: FeedWordPress now allows you to
automatically schedule checks for new posts without using external task
scheduling tools such as cron. In order to enable automatic updates, go
to **Syndication --> Options** and set "Check for new posts" to
"automatically." For details, see "Automatic Feed Updates" in
README.text.
An important side-effect of the changes to the update system is that if
you were previously using the cron job and the `update-feeds.php` script
to schedule updates, you need to change your cron set-up. The old
`update-feeds.php` script no longer exists. Instead, if you wish to use
a cron job to guarantee updates on a particular schedule, you should
have the cron job fetch the front page of your blog (for example, by
using `curl http://www.zyx.com/blog/ > /dev/null`) instead of activating
the `update-feeds.php` script. If automatic updates have been enabled,
fetching the front page will automatically trigger the update process.
* INTERFACE REORGANIZATION: All FeedWordPress functions are now located
under a top-level "Syndication" menu in the WordPress Dashboard. To
manage the list of syndicated sites, manually check for new posts on
one or more feeds, or syndicate a new site, you should use the main page
under **Syndication**. To change global settings for FeedWordPress,
you should use **Syndication --> Options**.
* FILE STRUCTURE REORGANIZATION: Due to a combination of changing styles
for FeedWordPress plugins and lingering bugs in the FeedWordPress admin
menu code, the code for FeedWordPress is now contained in two different
PHP files, which should be installed together in a subdirectory of your
plugins directory named `feedwordpress`. (See README.text for
installation and upgrade instructions relating to the change.)
* MULTIPLE CATEGORIES SETTING: Some feeds use non-standard methods to
indicate multiple categories within a single category element. (The most
popular site to do this is del.icio.us, which separates tags with a
space.) FeedWordPress now allows you to set an optional setting, for any
feed which does this, indicating the character or characters used to
divide multiple categories, using a Perl-compatible regular expression.
(In the case of del.icio.us feeds, FeedWordPress will automatically use
\s for the pattern without your having to do any further configuration.)
To turn this setting on, simply use the "Edit" link for the feed that
you want to turn it on for.
* REGULAR EXPRESSION BUG FIXED: Eliminated a minor bug in the regular
expressions for e-mail addresses (used in parsing RSS `author`
elements), which could produce unsightly error messages for some users
parsing RSS 2.0 feeds.
* DATE / UPDATE BUG FIXED: A bug in date handling was eliminated that may
have caused problems if any of (1) WordPress, or (2) PHP, or (3) your
web server, or (4) your MySQL server, has been set to use a different
time zone from the one that any of the others is set to use. If
FeedWordPress has not been properly updating updated posts, or has been
updating posts when there shouldn't be any changes for the update, this
release may solve that problem.
* GOOGLE READER BUGS FIXED: A couple of bugs that made it difficult for
FeedWordPress to interact with Google Reader public feeds have been
fixed. Firstly, if you encountered an error message reading "There was a
problem adding the newsfeed. [SQL: ]" when you tried to add the feed,
the cause of this error has been fixed. Secondly, if you succeeded in
getting FeedWordPress to check a Google Reader feed, only to find that
the title of posts had junk squashed on to the end of them, that bug
has been fixed too. To fix this bug, you must install the newest version
of the optional MagpieRSS upgrade.
* FILTER PARAMETERS: Due to an old, old bug in WordPress 1.5.0 (which was
what was available back when I first wrote the filter interface),
FeedWordPress has traditionally only passed one parameter to
syndicated_item and syndicated_post filters functions -- an array
containing either the Magpie representation of a syndicated item from
the feed, or the database representation of a post about to be inserted
into the WordPress database. If you needed information about the feed
that the item came from, this was accessible only through a pair of
global variables, $fwp_channel and $fwp_feedmeta.
Since it's been a pretty long time since WordPress 1.5.0 was in
widespread usage, I have gone ahead and added an optional second
parameter to the invocation of the syndicated_item and syndicated_post
filters. If you have written a filter for FeedWordPress that uses either
of these hooks, you can now register that filter to accept 2 parameters.
If you do so, the second parameter will be a SyndicatedPost object,
which, among other things, allows you to access information about the
feed from which an item is syndicated using the $post->feed and the
$post->feedmeta elements (where $post is the name of the second
parameter).
NOTE THAT THE OLD GLOBAL VARIABLES ARE STILL AVAILABLE, for the time
being at least, so existing filters will not break with the upgrade.
They should be considered deprecated, however, and may be eliminated in
the future.
* FILTER CHANGE / BUGFIX: the array that is passed as the first argument
syndicated_post filters no longer is no longer backslash-escaped for
MySQL when filters are called. This was originally a bug, or an
oversight; the contents of the array should only be escaped for the
database *after* they have gone through all filters. IF YOU HAVE WRITTEN
ANY syndicated_post FILTERS THAT PRESUME THE OLD BEHAVIOR OF PASSING IN
STRINGS THAT ARE ALREADY BACKSLASH-ESCAPED, UPDATE YOUR FILTERS
ACCORDINGLY.
* OTHER MINOR BUGFIXES AND INTERNAL CHANGES: The internal architecture of
FeedWordPress has been significantly changed to make the code more
modular and clean; hopefully this should help reduce the number of
compatibility updates that are needed, and make them easier and quicker
when they are needed.
= 0.981 =
Version 0.981 is a narrowly targeted bugfix and compatibility release, whose
main purpose is to resolve a major outstanding problem: the incompatibility
between version 0.98 of WordPress and the recently released WordPress 2.1.
* WORDPRESS 2.1 COMPATIBILITY: FeedWordPress is now compatible with
WordPress 2.1, as well as retaining its existing support for WordPress
2.0 and 1.5. Incompatibilities that resulted in database warnings, fatal
errors, and which prevented FeedWordPress from syndicating new posts,
have been eliminated.
* RSS-FUNCTIONS.PHP RENAMED TO RSS.PHP: if you use the upgraded MagpieRSS
replacement that's included with FeedWordPress, be sure to note that
there are now *two* files to upload from the `OPTIONAL/wp-includes`
subdirectory in order to carry out the upgrade: rss-functions.php and
rss.php. **It is necessary to upload both files**, due to a change in
the file naming scheme in WordPress 2.1, and it is necessary to do so
whether you are using WordPress 2.1 or not. If you only upload the
`rss-functions.php` file as in previous installations you will not have
a working copy of MagpieRSS; the rss.php file contains the actual code.
* DATE BUG AFFECTING SOME PHP INSTALLATIONS RESOLVED: due to a subtle bug
in parse_w3cdtf(), some installations of PHP encountered problems with
FeedWordPress's attempt to date posts, which would cause some new posts
on Atom feeds to be dated as if they had apppeared in 1969 or 1970
(thus, effectively, never appearing on front page at all). This bug in
the date handling should now be fixed.
* PHP <?=...?> SHORT FORM ELIMINATED: some installations of PHP do not
allow the <?=...?> short form for printing PHP values, which was used
extensively in the FeedWordPress interface code. Since this could cause
fatal errors for users with the wrong installation of PHP, the short
form has been replaced with full PHP echo statements, and is no longer
used in FeedWordPress.
* BETTER USER INTERFACE INTEGRATION WITH WORDPRESS 2.x: Some minor changes
have been made to help the FeedWordPress interface pages blend in better
with the user interface when running under WordPress 2.x.
* GLOBAL CATEGORIES BUG RESOLVED: a bug that prevented some users from
setting one or more categories to apply to syndicated posts from all
feeds (using the checkbox interface under Options --> Syndication) has
been resolved.
= 0.98 =
* WORDPRESS 2.0 COMPATIBILITY: This is a narrowly-targeted release to
solve a major outstanding problem. FeedWordPress is now compatible with
both WordPress 1.5 and WordPress 2.0. Incompatibilities that caused
fatal SQL errors, and a more subtle bug with off-kilter counts of posts
under a given category, have been resolved. FeedWordPress tests for
database schema using the global $wp_db_version variable (if null, then
we presume that we're dealing with WordPress 1.5).
NOTE: I have **not** fully tested FeedWordPress with WordPress 2.0.
Further testing may reveal more bugs. However, you should now be able
to get at least basic FeedWordPress functionality up and running.
* AUTHOR MATCHING: FeedWordPress tests several fields to see if it can
identify the author of the post as a user already in the WordPress user
database. In previous versions, it tested the user login, the nickname,
and tested for "aliases" listed in the Profile (see documentation). FWP
now also matches authors on the basis of e-mail address (*if* an e-mail
address is present). This is particularly helpful for formats such as
RSS 2.0, in which authors are primarily identified by e-mail addresses.
= 0.97 =
* INSTALLATION PROCEDURE: Some of the changes between 0.96 and 0.97
require upgrades to the meta-data stored by FeedWordPress to work
properly. Thus, if you are upgrading from 0.96 or earlier to 0.97, most
FeedWordPress operations (including updates and template functions)
WILL BE DISABLED until you run the upgrade procedure. Fortunately,
running the upgrade procedure is easy: just go to either Options -->
Syndication or Links --> Syndicated in the WordPress Dashboard and press
the button.
* FEED FORMAT SUPPORT: Support has been added for the Atom 1.0 IETF
standard. Several other elements are also newly supported
(dcterms:created, dcterms:issued, dcterms:modified, dc:identifier,
proper support for the RSS 2.0 guid element, the RSS 2.0 author element,
the use of Atom author or Dublin Core dc:creator constructs at the feed
level to identify the author of individual items, etc.)
N.B.: full support of several Atom 1.0 features, such as categories
and enclosures, requires you to install the optional rss-functions.php
upgrade in your wp-includes directory.
* BUG FIX: Running `update-feeds.php` from command line or crontab
returned "I don't syndicate..." errors. It turns out that WordPress
sometimes tramples on the internal PHP superglobals that I depended on
to determine whether or not the script was being invoked from the
command line. This has been fixed (the variables are now checked
*before* WordPress can trample them). Note that `update-feeds.php` has
been thoroughly overhauled anyway; see below for details.
* BUG FIX: Duplicate categories or author names. Fixed two bugs that could
create duplicate author and/or category names when the name contained
either (a) certain international characters (causing a mismatch between
MySQL and PHP's handling of lowercasing text), or (b) characters that
have a special meaning in regular expressions (causing MySQL errors when
looking for the author or category due to regexp syntax errors). These
should now be fixed thanks to careful escaping of names that go into
regular expressions and careful matching of lowercasing functions
(comparing results from PHP only to other results from PHP, and results
from MySQL only to other results from MySQL).
* BUG FIX: Items dated December 31, 1969 should appear less often. The
function for parsing W3C date-time format dates that ships with
MagpieRSS can only correctly parse fully-specified dates with a
fully-specified time, but valid W3C date-time format dates may omit the
time, the day of the month, or even the month. Some feeds in the wild
date their items with coarse-grained dates, so the optional
`rss-functions.php` upgrade now includes a more flexible parse_w3cdtf()
function that will work with both coarse-grained and fully-specified
dates. (If parts of the date or the time are omitted, they are filled in
with values based on the current time, so '2005-09-10' will be dated to
the current time on that day; '2004' will be dated to this day and time
one year ago.
N.B.: This fix is only available in the optional `rss-functions.php`
upgrade.
* BUG FIX: Evil use of HTTP GET has been undone. The WordPress interface
is riddled with inappropriate (non-idempotent) uses of HTTP GET queries
(ordinary links that make the server do something with significant
side-effects, such as deleting a post or a link from the database).
FeedWordPress did some of this too, especially in places where it aped
the WordPress interface (e.g. the "Delete" links in Links -->
Syndicated). That's bad business, though. I've changed the interface so
that all the examples of improper side-effects that I can find now
require an HTTP POST to take effect. I think I got pretty much
everything; if there's anything that I missed, let me know.
Further reading: [Sam Ruby 2005-05-06: This Stuff Matters](http://www.intertwingly.net/blog/2005/05/06/This-Stuff-Matters)
* BUG FIX: Categories applied by `cats` setting should no longer prevent
category-based filtering from working. In FeedWordPress, you can (1)
apply certain categories to all syndicated posts, or all posts from
a particular feed; and (2) filter out all posts that don't match one
of the categories that are already in the WordPress database (allowing
for simple category-based filtering; just load up WordPress with the
categories you want to accept, and then tell FeedWordPress not to create
new ones). However, the way that (1) and (2) were implemented meant that
you couldn't effectively use them together; once you applied a known
category to all syndicated posts from a particular feed, it meant that
they'd have at least one familiar category (the category or categories
you were applying), and that would get all posts past the filter no
matter what categories they were originally from.
Well, no longer. You can still apply categories to all syndicated posts
(using either Syndication --> Options, or the feed-level settings under
Links --> Syndicated). But these categories are not applied to the post
until *after* it has already passed by the "familiar categories" filter.
So now, if you want, you can do category filtering and *then* apply as
many categories as you please to all and only posts that pass the filter.
* BUG FIX: Other minor typos and HTML gaffes were fixed along the way.
* PERFORMANCE: get_feed_meta() no longer hits the database for information
on every call; it now caches link data in memory, so FeedWordPress only
goes to the database once for each syndicated link. This may
substantially improve performance if your database server resources
are tight and your templates make a lot of use of custom settings from
get_feed_meta().
* API CHANGE: Link ID numbers, rather than RSS URIs, are now used to
identify the feed from which a post is syndicated when you use template
functions such as get_feed_meta(). The practical upshot of this is you
can switch feeds, or change the feed address for a particular syndicated
site, without breaking your templates for all the posts that were
syndicated from the earlier URI.
* API CHANGE: if you have plugins or templates that make use of the
get_feed_meta() function or the $fwp_feedmeta global, note that the
data formerly located under the `uri` and `name` fields is now located
under the `link/uri` field and the `link/name` field, respectively. Note
also that you can access the link ID number for any given feed under the
global $fwp_feedmeta['link/id'] (in plugins) or
get_feed_meta('link/id') (in a template in post contexts).
* FEATURE: the settings for individual feeds can now be edited using a
humane interface (where formerly you had to tweak key-value pairs in the
Link Notes section). To edit settings for a feed, pick the feed that you
want under Links --> Syndicated and click the Edit link.
* FEATURE: The "Unsubscribe" button (formerly "Delete") in Links -->
Syndicated now offers three options for unsubscribing from a feed: (1)
turning off the subscription without deleting the feed data or affecting
posts that were syndicated from the feed (this works by setting the Link
for the feed as "invisible"); (2) deleting the feed data and all of the
posts that were syndicated from the feed; or (3) deleting the feed data
and *keeping* the posts that were syndicated from the feed
setting the Link to "Invisible" (meaning that it will not be displayed
in lists of the site links on the front page, and it won't be checked
for updates; (2) deleting the Link and all of the posts that were
syndicated from its feed; or (3) deleting the feed data but keeping the
posts that were syndicated (which will henceforward be treated as if
they were local rather than syndicated posts). (Note that (1) is usually
the best option for aggregator sites, unless you want to clean up the
results of an error or a test.)
* FEATURE / BUG FIX: If you have been receiving mysterious "I don't
syndicate...", or "(local) HTTP status code was not 200", or "(local)
transport error - could not open socket", or "parse error - not well
formed" errors, then this update may solve your problems, and if it does
*not* solve them, it will at least make the reasons for the problems
easier to understand. That's because I've overhauled the way that
FeedWordPress goes about updating feeds.
If you use the command-line PHP scripting method to run scheduled
updates, then not much should change for you, except for fewer
mysterious errors. If you have done updates by sending periodic HTTP
requests to <http://your-blog.com/path/wp-content/update-feeds.php>,
then the details have changed somewhat; mostly in such a way as to make
things easier on you. See the README file or online documentation on
Staying Current for the details.
* FEATURE: FeedWordPress now features a more sophisticated system for
timed updates. Instead of polling *every* subscribed feed for updates
*each* time `update-feeds.php` is run, FeedWordPress now keeps track of
the last time it polled each feed, and only polls them again after a
certain period of time has passed. The amount of time is normally set
randomly for each feed, in a period between 30 minutes and 2 hours (so
as to stagger updates over time rather than polling all of the feeds at once. However, the length of time between updates can also be set
directly by the feed, which brings us to ...
* FEATURE: FeedWordPress now respects the settings in the `ttl` and
Syndication Module RSS elements. Feeds with these elements set will not
be polled any more frequently than they indicate with these feeds unless
the user manually forces FeedWordPress to poll the feed (see Links -->
Syndicated --> Edit settings).
= 0.96 =
* FEATURE: support has been added for enclosures in RSS 2.0 and Atom
0.6+ newsfeeds. WordPress already supports adding enclosures to an
item; FeedWordPress merely gets the information on the enclosure
from the feed it is syndicating and plugs that information directly
into the WordPress database so that (among other things) that post
will have its enclosure listed in your blog's RSS 2 newsfeed.
Note that enclosure support requires using the optional MagpieRSS
upgrade (i.e., replacing your `wp-includes/rss-functions.php` with
`OPTIONAL/wp-includes/rss-functions.php` from the FWP archive)
* FEATURE: for completeness's sake, there is now a feed setting,
`hardcode url`, that allows you to set the URI for the front page
of a contributor's website manually (that is, prevent it from being
automatically updated from the feed channel link on each update). To
set the URI manually, put a line like this in the Link Notes section
of a feed:
hardcode url: yes
You can also instruct FeedWordPress to use hardcoded URIs by default
on all feeds using Options --> Syndication
* FEATURE: by default, when FeedWordPress finds new syndicated posts,
it (1) publishes them immediately, (2) turns comments off, and (3)
turns trackback / pingback pings off. You can now alter all three
default behaviors (e.g., to allow pings on syndicated posts, or to
send newly-syndicated posts to the draft pile for moderation) using
Options --> Syndication
= From 0.91 to 0.95 =
* BUG FIX: Fixed an obscure bug in the handling of categories:
categories with trailing whitespace could cause categories with
duplicate names to be created. This no longer happens. While I was
at it I tightened up the operation of
FeedWordPress::lookup_categories() a bit in general.
* FEATURE DEPRECATED: the feed setting `hardcode categories` is now
deprecated in favor of `unknown categories` (see below), which
allows you to strip off any syndication categories not already in
your database using `unknown categories: default` or `unknown
categories: filter`. If you have `hardcode categories: yes` set on a
feed, this will be treated as `unknown categories: default` (i.e.,
no new categories will be added, but if a post doesn't match any of
the categories it will be added in the default category--usually
"Uncategorized" or "General").
* FEATURE: You can now set global defaults as to whether or not
FeedWordPress will update the Link Name and Link Description
settings for feeds automatically from the feed title and feed
tagline. (By default, it does, as it has in past versions.) Whether
this behavior is turned on or off, you can still override the
default behavior using feed settings of `hardcode name: yes`,
`hardcode name: no`, `hardcode description: yes`, or `hardcode
description: no`.
* FEATURE: Users can now provide one or several "aliases" for an
author, just as they can for a category. For example, to make
FeedWordPress treat posts by "Joseph Cardinal Ratzinger" and "Pope
Benedict XVI" as by the same author, edit the user profile for Pope
Benedict XVI and add a line like this to the "User profile" field:
a.k.a.: Joseph Cardinal Ratzinger
You can add several aliases, each on a line by itself. You can also
add any other text you like to the Profile without interfering with
the aliases.
* FEATURE: Users can now choose how to handle syndicated posts that
are in unfamiliar categories or by unfamiliar authors (i.e.,
categories or authors whose names are not yet in the WordPress
database). By default, FeedWordPress will (as before) create a new
category (or new author) and use it for the current post and any
future posts. This behavior can be changed, either for all feeds or
for one or another particular feed.
There are now three different options for an unfamiliar author: (1)
FeedWordPress can create a new author account and attribute the
syndicated post to the new account; (2) FeedWordPress can attribute
the post to an author if the author's name is familiar, and to a
default author (currently, this means the Site Administrator
account) if it is not; (3) FeedWordPress can drop posts by
unfamiliar authors and syndicate only posts by authors who are
already in the database.
There are, similarly, two different options for an unfamiliar
category: (1) FeedWordPress can create new categories and place the
syndicated post in them; (2) FeedWordPress can drop the unfamiliar
categories and place syndicated posts only in categories that it is
already familiar with. In addition, FeedWordPress 0.95 lets you
choose whether posts that are in *no* familiar categories should be
syndicated (and placed in the default category for the blog) or
simply dropped.
You can set the default behavior for both authors and categories
using the settings in Options --> Syndication. You can also set
different behavior for specific feeds by adding the `unfamiliar
author` and / or `unfamiliar categories` settings to the Link Notes
section of a feed:
unfamiliar author: (create|default|filter)
unfamiliar categories: (create|default|filter)
A setting of `unfamiliar author: create` will make FeedWordPress
create new authors to match unfamiliar author names *for this feed
alone*. A setting of `unfamiliar author: default` will make it
assign posts from unfamiliar authors to the default user account. A
setting of `unfamiliar author: filter` will cause all posts (from
this feed alone) to be dropped unless they are by an author already
listed in the database. Similiarly, `unfamiliar categories: create`
will make FeedWordPress create new categories to match unfamiliar
category names *for this feed alone*; `unfamiliar categories:
default` will cause it to drop any unfamiliar category names; and
`unfamiliar categories: filter` will cause it to *both* drop any
unfamiliar category names *and* to only syndicate posts that are
placed in one or more familiar categories.
These two new features allow users to do some coarse-grained
filtering without having to write a PHP filter. Specifically, they
offer an easy way for you to filter feeds by category or by author.
Suppose, for example, that you only wanted to syndicate posts that
your contributors place in the "Llamas" category. You could do so by
setting up your installation of WordPress so that the only category
in the database is "Llamas," and then use Options --> Syndication to
set "Unfamiliar categories" to "don't create new categories and
don't syndicate posts unless they match at least one familiar
category". Now, when you update, only posts in the "Llamas" category
will be syndicated by FeedWordPress.
Similarly, if you wanted to filter one particular feed so that only
posts by (for example) the author "Earl J. Llama" were syndicated to
your site, you could do so by creating a user account for Earl J.
Llama, then adding the following line to the settings for the feed
in Link Notes:
unfamiliar author: filter
This will cause any posts from this feed that are not authored by
Earl J. Llama to be discarded, and only the posts by Earl J. Llama
will be syndicated. (If the setting is used on one specific feed, it
will not affect how posts from other feeds are syndicated.)
