17 Laconica (pronounced "luh-KAWN-ih-kuh") is a Free and Open Source
18 microblogging platform. It helps people in a community, company or
19 group to exchange short (140 character) messages over the Web. Users
20 can choose which people to "follow" and receive only their friends' or
21 colleagues' status messages. It provides a similar service to sites

24 With a little work, status messages can be sent to mobile phones,
25 instant messenger programs (GTalk/Jabber), and specially-designed
26 desktop clients that support the Twitter API.

f66e996 Update version number to 0.7.4
Evan Prodromou authored
74 This is a minor bug-fix and feature release since version 0.7.3,
75 released Apr 4 2009. Notable changes this version:
76
77 - Improved handling of UTF-8 characters. The new code is *not* backwards
78 compatible by default; see "Upgrading" below for instructions on
79 converting existing databases to the correct character set.
80 - Unroll joins for large queries. This greatly enhanced database
81 performance -- up to 50x for some queries -- at the expense of making
82 an extra DB hit for some queries.
83 - Added an optional plugin to use WikiHashtags
84 (http://hashtags.wikia.com/) for the sidebar on hashtag pages.
85 - Optimized Twitter friend synchronization.
86 - Better error handling for Ajax posting of notices, including
87 HTTP errors and timeouts.
88 - Experimental Comet plugin -- supports the cometd and the Bayeux
89 protocol. Using this plugin, you can show "real time" updates on the
90 public and tag pages. However, server configuration is complex.
91 - If queues are enabled, update inboxes and memcached off-line. Speeds
92 up posting considerably.
93 - Correctly shorten links posted through XMPP.
94 - <link> elements for pagination, supported by some browsers like Opera.
95 - Corrected date format in search API.
96 - Made the public XRDS file work correctly.

98 Prerequisites
99 =============
100
101 The following software packages are *required* for this software to
102 run correctly.
103
104 - PHP 5.2.x. It may be possible to run this software on earlier
105 versions of PHP, but many of the functions used are only available
106 in PHP 5.2 or above.
107 - MySQL 5.x. The Laconica database is stored, by default, in a MySQL
108 server. It has been primarily tested on 5.x servers, although it may
109 be possible to install on earlier (or later!) versions. The server
110 *must* support the MyISAM storage engine -- the default for most
111 MySQL servers -- *and* the InnoDB storage engine.
112 - A Web server. Preferably, you should have Apache 2.2.x with the
8c10b0a fine-tuning the privacy flag
Evan Prodromou authored
113 mod_rewrite extension installed and enabled.
fbe15ef big changes to the README, part 1
Evan Prodromou authored
114
115 Your PHP installation must include the following PHP extensions:
116
117 - Curl. This is for fetching files by HTTP.
118 - XMLWriter. This is for formatting XML and HTML output.
119 - MySQL. For accessing the database.
a1434ee finish the README file

120 - GD. For scaling down avatar images.

Zach Copley authored
121 - mbstring. For handling Unicode (UTF-8) encoded strings.

Evan Prodromou authored
122 - gettext. For multiple languages. Default on many PHP installs.
fbe15ef big changes to the README, part 1
Evan Prodromou authored
123
124 For some functionality, you will also need the following extensions:
125
126 - Memcache. A client for the memcached server, which caches database
127 information in volatile memory. This is important for adequate
128 performance on high-traffic sites. You will also need a memcached
129 server to store the data in.
130 - Mailparse. Efficient parsing of email requires this extension.
131 Submission by email or SMS-over-email uses this extension.
525b867 sphinx documentation and sample config file
millette authored
132 - Sphinx Search. A client for the sphinx server, an alternative
133 to MySQL or Postgresql fulltext search. You will also need a
134 Sphinx server to serve the search queries.
135
fbe15ef big changes to the README, part 1
Evan Prodromou authored
136 You will almost definitely get 2-3 times better performance from your
137 site if you install a PHP bytecode cache/accelerator. Some well-known
138 examples are: eaccelerator, Turck mmcache, xcache, apc. Zend Optimizer
139 is a proprietary accelerator installed on some hosting sites.
140
141 External libraries
142 ------------------
143
144 A number of external PHP libraries are used to provide basic
145 functionality and optional functionality for your system. For your
146 convenience, they are available in the "extlib" directory of this
147 package, and you do not have to download and install them. However,
148 you may want to keep them up-to-date with the latest upstream version,
149 and the URLs are listed here for your convenience.

157 - PEAR DB. Although this is an older data access system (new
158 packages should probably use PHP DBO), the OpenID libraries
159 depend on PEAR DB so we use it here, too. DB_DataObject can
160 also use PEAR MDB2, which may give you better performance

172 library available for PHP. http://xmpphp.googlecode.com/. Note that
173 as of this writing the version of this library that is available in
174 the extlib directory is *significantly different* from the upstream
175 version (patches have been submitted). Upgrading to the upstream
176 version may render your Laconica site unable to send or receive XMPP
177 messages.

184 A design goal of Laconica is that the basic Web functionality should
185 work on even the most restrictive commercial hosting services.
186 However, additional functionality, such as receiving messages by
187 Jabber/GTalk, require that you be able to run long-running processes
188 on your account. In addition, posting by email or from SMS require
189 that you be able to install a mail filter in your mail server.
190
191 Installation
192 ============
193
194 Installing the basic Laconica Web component is relatively easy,
195 especially if you've previously installed PHP/MySQL packages.
196
197 1. Unpack the tarball you downloaded on your Web server. Usually a
198 command like this will work:

Evan Prodromou authored
203 directory. (If you don't have shell access on your Web server, you
204 may have to unpack the tarball on your local computer and FTP the
205 files to the server.)

208 directory. Usually something like this will work:

212 This will make your Laconica instance available in the mublog path of
213 your server, like "http://example.net/mublog". "microblog" or
214 "laconica" might also be good path names. If you know how to
215 configure virtual hosts on your web server, you can try setting up
216 "http://micro.example.net/" or the like.

227 If your Web server runs as another user besides "www-data", try
228 that user's default group instead. As a last resort, you can create
09ebc96 update README with new install instructions
Evan Prodromou authored
229 a new group like "mublog" and add the Web server's user to the group.

231 4. You should also take this moment to make your avatar subdirectory
232 writeable by the Web server. An insecure way to do this is:
233
234 chmod a+w /var/www/mublog/avatar
235
236 You can also make the avatar directory writeable by the Web server
237 group, as noted above.
238
239 5. Create a database to hold your microblog data. Something like this

250 service's documentation for how to create a new MySQL database.)
251
252 6. Create a new database account that Laconica will use to access the
253 database. If you have shell access, this will probably work from the
254 MySQL shell:

Evan Prodromou authored
261 username and password. You may want to test logging in to MySQL as
262 this new user.
263
264 7. In a browser, navigate to the Laconica install script; something like:
265
266 http://yourserver.example.com/mublog/install.php
267
268 Enter the database connection information and your site name. The
269 install program will configure your site and install the initial,
270 almost-empty database.
271
272 8. You should now be able to navigate to your microblog's main directory
273 and see the "Public Timeline", which will be empty. If not, magic
274 has happened! You can now register a new user, post some notices,
275 edit your profile, etc. However, you may want to wait to do that stuff
276 if you think you can set up "fancy URLs" (see below), since some
277 URLs are stored in the database.

302 1. Copy the htaccess.sample file to .htaccess in your Laconica
303 directory. Note: if you have control of your server's httpd.conf or
304 similar configuration files, it can greatly improve performance to
305 import the .htaccess file into your conf file instead. If you're
306 not sure how to do it, you may save yourself a lot of headache by
307 just leaving the .htaccess file.

310 to your Laconica installation on your server. Typically this will
311 be the path to your Laconica directory relative to your Web root.
312

325 Sphinx
326 ------
327
328 To use a Sphinx server to search users and notices, you also need
329 to install, compile and enable the sphinx pecl extension for php on the
330 client side, which itself depends on the sphinx development files.
331 "pecl install sphinx" should take care of that. Add "extension=sphinx.so"
332 to your php.ini and reload apache to enable it.
333
334 You can update your MySQL or Postgresql databases to drop their fulltext
335 search indexes, since they're now provided by sphinx.
336
337 On the sphinx server side, a script reads the main database and build
338 the keyword index. A cron job reads the database and keeps the sphinx
339 indexes up to date. scripts/sphinx-cron.sh should be called by cron
340 every 5 minutes, for example. scripts/sphinx.sh is an init.d script
341 to start and stop the sphinx search daemon.

343 SMS
344 ---
345
346 Laconica supports a cheap-and-dirty system for sending update messages
347 to mobile phones and for receiving updates from the mobile. Instead of
348 sending through the SMS network itself, which is costly and requires
349 buy-in from the wireless carriers, it simply piggybacks on the email
350 gateways that many carriers provide to their customers. So, SMS
351 configuration is essentially email configuration.
352
353 Each user sends to a made-up email address, which they keep a secret.
354 Incoming email that is "From" the user's SMS email address, and "To"
355 the users' secret email address on the site's domain, will be

357
358 For this to work, there *must* be a domain or sub-domain for which all
359 (or most) incoming email can pass through the incoming mail filter.
360
361 1. Run the SQL script carrier.sql in your Laconica database. This will
362 usually work:
363
364 mysql -u "lacuser" --password="lacpassword" laconica < db/carrier.sql
365
366 This will populate your database with a list of wireless carriers
367 that support email SMS gateways.

402 distribute messages via XMPP using the system below; however, you

404 well.
405
406 1. You may want to strongly consider setting up your own XMPP server.
407 Ejabberd, OpenFire, and JabberD are all Open Source servers.

422 On a default installation, your site can broadcast messages using
423 XMPP. Users won't be able to post messages using XMPP unless you've
424 got the XMPP daemon running. See 'Queues and daemons' below for how
425 to set that up. Also, once you have a sizable number of users, sending
426 a lot of SMS, OMB, and XMPP messages whenever someone posts a message
427 can really slow down your site; it may cause posting to timeout.

446 (Don't miss those square brackets at the end.) Note that your XMPP
447 broadcasting must be configured as mentioned above. Although you can
448 send out messages at "Web time", high-volume sites should strongly
449 consider setting up queues and daemons.
450
451 Queues and daemons
452 ------------------
453
454 Some activities that Laconica needs to do, like broadcast OMB, SMS,
455 and XMPP messages, can be 'queued' and done by off-line bots instead.
456 For this to work, you must be able to run long-running offline
457 processes, either on your main Web server or on another server you
458 control. (Your other server will still need all the above
459 prerequisites, with the exception of Apache.) Installing on a separate
460 server is probably a good idea for high-volume sites.
461
462 1. You'll need the "CLI" (command-line interface) version of PHP
463 installed on whatever server you use.
464
465 2. If you're using a separate server for queues, install Laconica
466 somewhere on the server. You don't need to worry about the
467 .htaccess file, but make sure that your config.php file is close
468 to, or identical to, your Web server's version.
469
470 3. In your config.php files (both the Web server and the queues
471 server!), set the following variable:
472
473 $config['queue']['enabled'] = true;

475 You may also want to look at the 'daemon' section of this file for
476 more daemon options. Note that if you set the 'user' and/or 'group'
477 options, you'll need to create that user and/or group by hand.

502
503 Note that these queue daemons are pretty raw, and need your care. In
504 particular, they leak memory, and you may want to restart them on a
505 regular (daily or so) basis with a cron job. Also, if they lose
506 the connection to the XMPP server for too long, they'll simply die. It
507 may be a good idea to use a daemon-monitoring service, like 'monit',
508 to check their status and keep them running.
509
510 All the daemons write their process IDs (pids) to /var/run/ by
511 default. This can be useful for starting, stopping, and monitoring the
512 daemons.

514 Twitter Friends Syncing
515 -----------------------
516
517 As of Laconica 0.6.3, users may set a flag in their settings ("Subscribe
518 to my Twitter friends here" under the Twitter tab) to have Laconica
519 attempt to locate and subscribe to "friends" (people they "follow") on
520 Twitter who also have accounts on your Laconica system, and who have
521 previously set up a link for automatically posting notices to Twitter.
522
523 Optionally, there is a script (./scripts/synctwitterfriends.php), meant
524 to be run periodically from a job scheduler (e.g.: cron under Unix), to
525 look for new additions to users' friends lists. Note that the friends
526 syncing only subscribes users to each other, it does not unsubscribe
527 users when they stop following each other on Twitter.
528
529 Sample cron job:

588
589 1. Choose your sitemap URL layout. Laconica creates a number of
590 sitemap XML files for different parts of your site. You may want to
591 put these in a sub-directory of your Laconica directory to avoid
592 clutter. The sitemap index file tells the search engines and other
593 bots where to find all the sitemap files; it *must* be in the main
594 installation directory or higher. Both types of file must be
595 available through HTTP.

Evan Prodromou authored
622 which is what the Identi.ca site uses, and "default", which is a good
623 basis for other sites.
624
625 As of right now, your ability to change the theme is site-wide; users
626 can't choose their own theme. Additionally, the only thing you can
627 change in the theme is CSS stylesheets and some image files; you can't
628 change the HTML output, like adding or removing menu items.
629
630 You can choose a theme using the $config['site']['theme'] element in
631 the config.php file. See below for details.
632
633 You can add your own theme by making a sub-directory of the 'theme'
634 subdirectory with the name of your theme. Each theme can have the
635 following files:
636
637 display.css: a CSS2 file for "default" styling for all browsers.
638 ie6.css: a CSS2 file for override styling for fixing up Internet
639 Explorer 6.
640 ie7.css: a CSS2 file for override styling for fixing up Internet
641 Explorer 7.
642 logo.png: a logo image for the site.
643 default-avatar-profile.png: a 96x96 pixel image to use as the avatar for
644 users who don't upload their own.
645 default-avatar-stream.png: Ditto, but 48x48. For streams of notices.
646 default-avatar-mini.png: Ditto ditto, but 24x24. For subscriptions
647 listing on profile pages.

683 management, but host it on a public server.
684
685 Note that this is an experimental feature; total privacy is not
686 guaranteed or ensured. Also, privacy is all-or-nothing for a site; you
687 can't have some accounts or notices private, and others public.
688 Finally, the interaction of private sites with OpenMicroBlogging is
689 undefined. Remote users won't be able to subscribe to users on a
690 private site, but users of the private site may be able to subscribe
691 to users on a remote site. (Or not... it's not well tested.) The
692 "proper behaviour" hasn't been defined here, so handle with care.

710 0. Download Laconica and set up all the prerequisites as if you were
711 doing a new install.
712 1. Make backups of both your database and your Web directory. UNDER NO
713 CIRCUMSTANCES should you try to do an upgrade without a known-good
714 backup. You have been warned.
715 2. Shut down Web access to your site, either by turning off your Web
716 server or by redirecting all pages to a "sorry, under maintenance"
717 page.
718 3. Shut down XMPP access to your site, typically by shutting down the
719 xmppdaemon.php process and all other daemons that you're running.
720 If you've got "monit" or "cron" automatically restarting your
721 daemons, make sure to turn that off, too.
722 4. Shut down SMS and email access to your site. The easy way to do
723 this is to comment out the line piping incoming email to your
724 maildaemon.php file, and running something like "newaliases".
725 5. Once all writing processes to your site are turned off, make a
726 final backup of the Web directory and database.
727 6. Move your Laconica directory to a backup spot, like "mublog.bak".
728 7. Unpack your Laconica 0.6 tarball and move it to "mublog" or
729 wherever your code used to be.

738
739 Here, rootuser and rootpassword are the username and password for a
740 user who can drop and create databases as well as tables; typically
741 that's _not_ the user Laconica runs as.
742 For PostgreSQL databases there is an equivalent, rebuilddb_psql.sh,
743 which operates slightly differently. Read the documentation in that
744 script before running it.
745 11. Use mysql or psql client to log into your database and make sure that
746 the notice, user, profile, subscription etc. tables are non-empty.

761 Notice inboxes
762 --------------
763
764 Before version 0.6.2, the page showing all notices from people the
765 user is subscribed to ("so-and-so with friends") was calculated at run
766 time. Starting with 0.6.2, we have a new data structure for holding a
767 user's "notice inbox". (Note: distinct from the "message inbox", which
768 is the "inbox" tab in the UI. The notice inbox appears under the
769 "Personal" tab.)
770
771 Notices are added to the inbox when they're created. This speeds up
772 the query considerably, and also allows us the opportunity, in the
773 future, to add different kind of notices to an inbox -- like @-replies
774 or subscriptions to search terms or hashtags.
775
776 Notice inboxes are enabled by default for new installations. If you
777 are upgrading an existing site, this means that your users will see
778 empty "Personal" pages. The following steps will help you fix the
779 problem.
780
781 0. $config['inboxes']['enabled'] can be set to one of three values. If
782 you set it to 'false', the site will work as before. Support for this
783 will probably be dropped in future versions.
784 1. Setting the flag to 'transitional' means that you're in transition.
785 In this mode, the code will run the "new query" or the "old query"
786 based on whether the user's inbox has been updated.
787 2. After setting the flag to "transitional", you can run the
788 fixup_inboxes.php script to create the inboxes. You may want to set
789 the memory limit high. You can re-run it without ill effect.
790 3. When fixup_inboxes is finished, you can set the enabled flag to
791 'true'.

793 UTF-8 Database
794 --------------
795
796 Laconica 0.7.4 introduced a fix for some incorrectly-stored
797 international characters ("UTF-8"). This fix is not
798 backwards-compatible; installations from before 0.7.4 will show
799 non-ASCII characters of old notices incorrectly. This section explains
800 what to do.
801
802 0. You can disable the new behaviour by setting the 'db''utf8' config
803 option to "false". You should only do this until you're ready to
804 convert your DB to the new format.
805 1. When you're ready to convert, you can run the fixup_utf8.php script
806 in the scripts/ subdirectory. If you've had the "new behaviour"
807 enabled (probably a good idea), you can give the ID of the first
808 "new" notice as a parameter, and only notices before that one will
809 be converted. Notices are converted in reverse chronological order,
810 so the most recent (and visible) ones will be converted first. The
811 script should work whether or not you have the 'db''utf8' config
812 option enabled.
813 2. When you're ready, set $config['db']['utf8'] to true, so that
814 new notices will be stored correctly.

816 Configuration options
817 =====================
818
819 The sole configuration file for Laconica (excepting configurations for
820 dependency software) is config.php in your Laconica directory. If you
821 edit any other file in the directory, like lib/common.php (where most
822 of the defaults are defined), you will lose your configuration options
823 in any upgrade, and you will wish that you had been more careful.
824
74bf2bf Enable configuration files in /etc/laconica/
Evan Prodromou authored
825 Starting with version 0.7.1, you can put config files in the
826 /etc/laconica/ directory on your server, if it exists. Config files
827 will be included in this order:
828
829 * /etc/laconica/laconica.php - server-wide config
830 * /etc/laconica/<servername>.php - for a virtual host
831 * /etc/laconica/<servername>_<pathname>.php - for a path
832 * INSTALLDIR/config.php - for a particular implementation
833

834 Almost all configuration options are made through a two-dimensional
835 associative array, cleverly named $config. A typical configuration
836 line will be:
837
838 $config['section']['option'] = value;
839
840 For brevity, the following documentation describes each section and
841 option.
842
843 site
844 ----
845
846 This section is a catch-all for site-wide variables.
847
848 name: the name of your site, like 'YourCompany Microblog'.
849 server: the server part of your site's URLs, like 'example.net'.

851 (installed in root).
852 fancy: whether or not your site uses fancy URLs (see Fancy URLs
853 section above). Default is false.

855 information to. You may want to use this if you don't have
856 access to syslog.
857 locale_path: full path to the directory for locale data. Unless you
858 store all your locale data in one place, you probably
859 don't need to use this.
860 language: default language for your site. Defaults to US English.
861 languages: A list of languages supported on your site. Typically you'd
862 only change this if you wanted to disable support for one
863 or another language:
864 "unset($config['site']['languages']['de'])" will disable
865 support for German.
866 theme: Theme for your site (see Theme section). Two themes are
867 provided by default: 'default' and 'stoica' (the one used by
868 Identi.ca). It's appreciated if you don't use the 'stoica' theme
869 except as the basis for your own.
870 email: contact email address for your site. By default, it's extracted
871 from your Web server environment; you may want to customize it.
872 broughtbyurl: name of an organization or individual who provides the
873 service. Each page will include a link to this name in the
874 footer. A good way to link to the blog, forum, wiki,
875 corporate portal, or whoever is making the service available.
876 broughtby: text used for the "brought by" link.
877 timezone: default timezone for message display. Users can set their
878 own time zone. Defaults to 'UTC', which is a pretty good default.
879 closed: If set to 'true', will disallow registration on your site.
880 This is a cheap way to restrict accounts to only one
881 individual or group; just register the accounts you want on
882 the service, *then* set this variable to 'true'.
3a246c1 add 'invite-only' mode for registration
Evan Prodromou authored
883 inviteonly: If set to 'true', will only allow registration if the user
884 was invited by an existing user.

885 private: If set to 'true', anonymous users will be redirected to the
886 'login' page. Also, API methods that normally require no
203bc45 @evanp documentation and version number

887 authentication will require it. Note that this does not turn
888 off registration; use 'closed' or 'inviteonly' for the
889 behaviour you want.
65bfda3 Documented the site notice option.
Evan Prodromou authored
890 notice: A plain string that will appear on every page. A good place
891 to put introductory information about your service, or info about
892 upgrades and outages, or other community info. Any HTML will
893 be escaped.
986a322 Limit duplicate notices in a particular time period (default 60s)
Evan Prodromou authored
894 dupelimit: Time in which it's not OK for the same person to post the
895 same notice; default = 60 seconds.
70d5fc4 Document the site-logo configuration option
Evan Prodromou authored
896 logo: URL of an image file to use as the logo for the site. Overrides
897 the logo in the theme, if any.
07eae0c Support SSL for some, all, or no pages
Evan Prodromou authored
898 ssl: Whether to use SSL and https:// URLs for some or all pages.
899 Possible values are 'always' (use it for all pages), 'never'
900 (don't use it for any pages), or 'sometimes' (use it for
901 sensitive pages that include passwords like login and registration,
902 but not for regular pages). Default to 'never'.
903 sslserver: use an alternate server name for SSL URLs, like
904 'secure.example.org'. You should be careful to set cookie
905 parameters correctly so that both the SSL server and the
906 "normal" server can access the session cookie and
907 preferably other cookies as well.

919 really know what you're doing), 'username' is the username,
920 'password' is the password, and etc.
921 ini_yourdbname: if your database is not named 'laconica', you'll need
922 to set this to point to the location of the
923 laconica.ini file. Note that the real name of your database
924 should go in there, not literally 'yourdbname'.
925 db_driver: You can try changing this to 'MDB2' to use the other driver
926 type for DB_DataObject, but note that it breaks the OpenID
927 libraries, which only support PEAR::DB.
928 debug: On a database error, you may get a message saying to set this
929 value to 5 to see debug messages in the browser. This breaks
930 just about all pages, and will also expose the username and

932 quote_identifiers: Set this to true if you're using postgresql.
933 type: either 'mysql' or 'postgresql' (used for some bits of
934 database-type-specific SQL in the code). Defaults to mysql.
935 mirror: you can set this to an array of DSNs, like the above
936 'database' value. If it's set, certain read-only actions will
937 use a random value out of this array for the database, rather
938 than the one in 'database' (actually, 'database' is overwritten).
939 You can offload a busy DB server by setting up MySQL replication
940 and adding the slaves to this array. Note that if you want some
941 requests to go to the 'database' (master) server, you'll need
942 to include it in this array, too.

Evan Prodromou authored
943 utf8: whether to talk to the database in UTF-8 mode. This is the default
944 with new installations, but older sites may want to turn it off
945 until they get their databases fixed up. See "UTF-8 database"
946 above for details.

948 syslog
949 ------
950
951 By default, Laconica sites log error messages to the syslog facility.
952 (You can override this using the 'logfile' parameter described above).
953
954 appname: The name that Laconica uses to log messages. By default it's
955 "laconica", but if you have more than one installation on the
956 server, you may want to change the name for each instance so
957 you can track log messages more easily.
958
959 queue
960 -----
961
962 You can configure the software to queue time-consuming tasks, like
963 sending out SMS email or XMPP messages, for off-line processing. See
964 'Queues and daemons' above for how to set this up.

1052 server: server part of XMPP ID for update user.
1053 port: connection port for clients. Default 5222, which you probably
1054 shouldn't need to change.
1055 user: username for the client connection. Users will receive messages
1056 from 'user'@'server'.
1057 resource: a unique identifier for the connection to the server. This
1058 is actually used as a prefix for each XMPP component in the system.
1059 password: password for the user account.
1060 host: some XMPP domains are served by machines with a different
1061 hostname. (For example, @gmail.com GTalk users connect to
1062 talk.google.com). Set this to the correct hostname if that's the
1063 case with your server.
1064 encryption: Whether to encrypt the connection between Laconica and the
1065 XMPP server. Defaults to true, but you can get
1066 considerably better performance turning it off if you're
1067 connecting to a server on the same machine or on a
1068 protected network.
1069 debug: if turned on, this will make the XMPP library blurt out all of
1070 the incoming and outgoing messages as XML stanzas. Use as a
1071 last resort, and never turn it on if you don't have queues
1072 enabled, since it will spit out sensitive data to the browser.
1073 public: an array of JIDs to send _all_ notices to. This is useful for
1074 participating in third-party search and archiving services.

1092 stuff should usually go on Unix-ish systems.
1093 user: If set, the daemons will try to change their effective user ID
1094 to this user before running. Probably a good idea, especially if
1095 you start the daemons as root. Note: user name, like 'daemon',
1096 not 1001.

1111 base of the key is usually a simplified version of the site name
1112 (like "Identi.ca" => "identica"), but you can overwrite this if

1198 (run occasionally at Web time), 'cron' (run from a cron script),
1199 or 'never' (don't ever run). If you set it to 'cron', remember to
1200 schedule the script to run on a regular basis.
1201 frequency: if run value is 'web', how often to report statistics.
1202 Measured in Web hits; depends on how active your site is.
1203 Default is 10000 -- that is, one report every 10000 Web hits,
1204 on average.
1205 reporturl: URL to post statistics to. Defaults to Laconica developers'
1206 report system, but if they go evil or disappear you may
1207 need to update this to another value. Note: if you
1208 don't want to report stats, it's much better to
1209 set 'run' to 'never' than to set this value to something
1210 nonsensical.

1228 For quotas, be sure you've set the upload_max_filesize and post_max_size
1229 in php.ini to be large enough to handle your upload. In httpd.conf
1230 (if you're using apache), check that the LimitRequestBody directive isn't
1231 set too low (it's optional, so it may not be there at all).
1232
1233 file_quota: maximum size for a single file upload in bytes. A user can send
1234 any amount of notices with attachments as long as each attachment
1235 is smaller than file_quota.
1236 user_quota: total size in bytes a user can store on this server. Each user
1237 can store any number of files as long as their total size does
1238 not exceed the user_quota.
1239 monthly_quota: total size permitted in the current month. This is the total
1240 size in bytes that a user can upload each month.

1260 Some stuff for search.
1261
1262 type: type of search. Ignored if PostgreSQL or Sphinx are enabled. Can either
1263 be 'fulltext' (default) or 'like'. The former is faster and more efficient
1264 but requires the lame old MyISAM engine for MySQL. The latter
1265 will work with InnoDB but could be miserably slow on large
1266 systems. We'll probably add another type sometime in the future,
1267 with our own indexing system (maybe like MediaWiki's).

1272 The primary output for Laconica is syslog, unless you configured a

1285 Myths
1286 =====
1287
1288 These are some myths you may see on the Web about Laconica.
1289 Documentation from the core team about Laconica has been pretty
1290 sparse, so some backtracking and guesswork resulted in some incorrect
1291 assumptions.
1292
1293 - "Set $config['db']['debug'] = 5 to debug the database." This is an
1294 extremely bad idea. It's a tool built into DB_DataObject that will
1295 emit oodles of print lines directly to the browser of your users.
1296 Among these lines will be your database username and password. Do
1297 not enable this option on a production Web site for any reason.

1299 - "Edit dataobject.ini with the following settings..." dataobject.ini
1300 is a development file for the DB_DataObject framework and is not
1301 used by the running software. It was removed from the Laconica
1302 distribution because its presence was confusing. Do not bother
1303 configuring dataobject.ini, and do not put your database username
1304 and password into the file on a production Web server; unscrupulous
1305 persons may try to read it to get your passwords.
