    • CSSStyleSheet.href override
    • HTMLAnchorElement.toString() override
    • Avoid making <base>.href read-only
  • Proxy Mode Improvements:
    • To avoid breaking HTTPS envelope, if no content-length provided, chunked encoding is used (HTTP/1.1) or response is buffered and content-length is computed (HTTP/1.0)
    • Rewriter: Scheme-only rewriter converts embedded urls to http or https to match the scheme of containing page.
    • IP Resolver: Supports IP cache in Redis
    • Default resolver set to cookie resolver, eg. cookie_resolver: true is the default.

    • strip leading or trailing spaces in url
    • charset: default to utf-8 if unknown charset specified in HTML
  • live rewrite: LiveRewriter class overridable in config
  • WARC indexing: ignore empty records when indexing and continue, rather than stopping at first empty record.
  • tests: refactor integration tests to run signficantly faster.

pywb 0.10.9.1 changelist ~~~~~~~~~~~~~~~~~~~~~~

  • wombat: fix relative '/' rewrite which incorrectly handles rel scheme '//' urls

pywb 0.10.9 changelist

  • IPProxyResolver: Support new simple proxy resolver where collection and timestamp stored in server-side cache by IP and set via a rest api through pywb.proxy eg: curl -x "localhost:8080" http://pywb.proxy/set?ts=2015&coll=all. No cookies or proxy auth needed in this mode. Useful for Docker-based deployments where virtual IP is fixed. Enabled with cookie_resolver: ip in proxy_options.
  • CDX Server: Add support for timestamp-bounded queries CDX queries from= and to=, also support calendar query with (inclusive) ranges, eg. /2010-2015/example.com, /2010-/example.com/, /-2015/example.com/.
  • Proxy options: add use_banner to toggle banner insert, and use_client_rewrite to toggle wombat rewriting in proxy mode. (Client rewriting requires banner insert).
  • Proxy and Video: When in proxy mode, load youtube-dl video info via proxy magic host pywb.proxy, and ensure CORS support.
  • Rewrite: ensure <base> tag has trailing slash, or add <base> with trailing slash for host-name only urls, eg: http://localhost:8080/example.com

  • 10-field CDX format fully supported.
  • rewrite: "background" attr rewriting, proper rewriting of entity-encoded attributes.
  • Fix for regression for Vimeo videos that were recorded as Flash but replay as HTML.

pywb 0.10.6 changelist

  • Disable url rewriting in JS by default! No longer needed due to improved client side rewriting of all urls.

  • wombat 2.7 more rewriting improvements:

    • document.write override rewrites all elements, not just one top level elements.
    • iframe srcdoc also rewritten.
    • support for custom modifiers, such as js_ for SCRIPT tag rewriting, otherwise for element overrides.
    • improved css rewriting, override standard css attributes on CSSStyleDeclaration to avoid mutation observers, rewrite STYLE text content.
    • postMessage: original source window now also preserved along with origin.
    • cookie rewrite: don't remove expires, but adjust by date offset. Allow cookies to be deleted by setting to expired date.
  • Embed mode, pywb framed replay can now be embedded in an iframe when embeddable: True option is set. postMessage on framed replay proxies between replay frame and embedded frame, and window.parent is not set to top replay frame, allowing access to containing frame.
  • vidrw: don't replace video with generic swf, find better match.
  • path index loader: ensure each request handled by own file reader.

pywb 0.10.5 changelist

  • wombat 2.6 client side rewriting improvements:

    • Override JS prototype getters and setters on href and src attributes of standard HTML elements, so that JavaScript access receives and sets the original url, but the element actually contains the rewritten url internally.
    • For <a> element override other url properties href, hostname, host, pathname, origin, search, port, protocol
    • Improved postMessage emulation: Ensure the original origin of the caller is saved, by wrapping X.postMessage in a special X.__WB_pmw(window).postMessage() call which will save origin of current window in X. Store origin and destination hosts.
    • Improved message listener emulation: Add filtering to skip messages that were not inteded for destination host.
    • Restored wombat if wiped by document.write / document.open (happens on FF).
    • When rewriting html for document.write, keep <html>, <head>, <body> tags in rewritten html.
  • Relative urls rewritten to stay relative, eg. /path/file.html -> /coll/http://example.com/path/file.html Can be disabled with no_match_rel=True in rewrite_opts.
  • Optional force_html_decl option to add a <!DOCTYPE> or other HTML declaration if none is present.
  • Improved handling for redir_to_exact=False mode. When set, no redirect on memento timegate, and serve Content-Location ` headers for actual memento, in conformance with Mememnto RFC Pattern 2.2 (http://tools.ietf.org/html/rfc7089#section-4.2.2)
  • Proxy Mode Fixes: Ensure Content-Length header is always added and correct in proxy mode, needed for proper HTTPS handling within CONNECT envelope.
  • New default HostScopeCookieRewriter sets cookies with domain /coll/https://example.com/ instead of /coll/. Can be specified with cookie_scope: host per collection. This is now the default live rewrite proxy and should be much safer/secure. For rare login use cases, the collection root scope can be specified with cookie_scope: coll.
  • Cookie Path= value always a relative path for all cookie scopes, previously were often absolute paths.
  • Default WSGI handler for wayback back to wsgiref, as waitress does not support proxy mode.

pywb 0.10.2 changelist

  • wombat 2.5 update -- significant wombat improvements:

    • Cookies: more comprehensive client-side cookie overriding, including Path, Domain, and expires removal.
    • WB_wombat_location overriden on Object prototype, defaults to location if _WB_wombat_location, the actual, property is not set.
    • WB_wombat_location.href proxies to actual location, responsive to pushState / replaceState location changes.
    • .href and .src attributes correctly return original url in JavaScript.
    • More consistent and lookupGetter/lookupSetter overrides with Object.defineProperty.
    • Added baseURI override, Element.prototype anddocument``.

    • Improved iframe override, including check for contentDocument changes.
    • Don't rewrite urls that start with {
  • Frames mode: ensure hash changes synchronized between inner and outer frames.
  • video: don't rewrite generic 'swf' with flowplayer
  • deprefix: support deprefixing of url-encoded queries.

pywb 0.10.1 changelist

  • Support Content-Encoding: deflate which was not being handled.
  • Fix issues with fallback handlers: A POST request could result in double read of POST input data.
  • youtube-dl removed from dependency as it is only needed for live proxy. (related tests only run if youtube-dl is installed).

pywb 0.10.0 changelist

  • Per-collection cacheing settings: rewrite_opts.http_cache can be set to:

    • pass - keep cacheing headers as-is (applies to Cache-Control, Expires, Etag and Last-Modified)
    • 0 - add Cache-Control: no-cache; no-store
    • N - add Cache-Control: max-age=N and corresponding Expires header
    • None (default) -- Rewrite cache headers, effectively removing them (current behavior)

  • New improved Wombat, including:

    • better handling of new iframes set to about:blank, add all overrides
    • createElement() override (can be disabled)
    • innerHTML prototype override (can be disabled)

  • wombat fixes: fixes situation where setAttribute was not being rewritten.
  • wombat fixes: obey _no_rewrite==true more consistently in rewrite_elem
  • wombat fixes: remove incorrect timezone offset in Date override.
  • wombat: new 'node added' mutation observer which will rewrite any newly added elements, may simplify other rewriting cases. Not enabled by default yet requires setting client.use_node_observers to use.
  • regex rewrite: tweak top and scheme relative regexes to better avoid false positives
  • html rewrite: handle parse_comments by rewriting as html, instead of as javascript.
  • html rewrite: if html content has no <head> tags and no body tags, insert head_insert at end of document.
  • html rewrite: don't insert banner in ajax requests, wombat always adds X-Requested-With: XMLHttpRequest.
  • scheme relative urls: rewrite to current scheme, if known, otherwise keep scheme relative, instead of defaulting to http.

pywb 0.9.7 changelist

  • wombat enchancements: support for mutation observers instead of setAttribute override with client.use_attr_observers setting. Can also disable worker override with skip_disable_worker
  • wombat fixes: Better check for self-redirect when proxying replace() and assign(), use querySelectorAll() for dom selection
  • wombat fixes: Don't remove trailing slash in extract_orig(), treat slash and no-slash urls as distinct on the client (as expected).
  • cdx-indexer: Validation of HTTP protocol and request verbs now optional. Any protocol and verb will be accepted, unless -v flag is used, allowing for indexing of content with custom verbs, unexpected protocol, etc...

pywb 0.9.6 changelist

  • framed replay: fix bug where outer frame url was not updated (in inverse mode) after navigating inner frame.
  • framed replay: lookup frame by id, replay_iframe, instead of by using window.frames[0] to allow for more customization.
  • fix typo in wombat no_rewrite_prefixes

pywb 0.9.5 changelist

  • s3 loading: support s3:// scheme in block loader, allowing for loading index and archive files from s3. boto library must be installed seperately via pip install boto. Attempt default boto auth path, and if that fails, attempt anonymous s3 connection.

  • Wombat/Client-Side Rewrite Customizations: New rewrite_opts.client settings from config.yaml are passed directly to wombat as json.

    Allows for customizing wombat as needed. Currently supported options are: no_rewrite_prefixes for ignoring rewrite on certain domains, and skip_dom, skip_setAttribute and skip_postmessage options for disabling those overrides. Example usage in config:

    rewrite_opts:
    ...
    client:
        no_rewrite_prefixes: ['http://dont-rewrite-this.example.com/']

        skip_setAttribute: true
        skip_dom: true
        skip_postmessage: true
  • Revamp template setup: All templates now use shared env, which is created on first use or can be explicitly set (if embedding) via J2TemplateView.init_shared_env() call. Support for specifiying a base env, as well as custom template lookup paths also provided
  • Template lookup paths can also be set via config options templates_dirs. The default list is: templates, ., / in that order.
  • Embedding improvements: move custom env (REL_REQUEST_URI setup) into routers, should be able to call router created by create_wb_router() directly with WSGI enviorn and receive a callable response.
  • Embedding improvements: If set, the contents of environ['pywb.template_params'] dictionary are added directly to Jinja context, allowing for custom template params to be passed to pywb jinja templates.
  • Root collection support: Can specify a route with '' which will be the root collection. Fix routing paths to ensure root collection is checked last.
  • Customization: support custom route_class for cdx server and pass wbrequest to not_found_html error handlers.
  • Manager: Validate collection names to start with word char and contain alphanum or dash only.
  • CLI refactor: easier to create custom cli apps and pass params, inherit shared params. live-rewrite-server uses new system cli system, defaults to framed inverse mode. Also runs on /live/ path by default. See live-rewrite-server -h for a list of current options.
  • Add cookie_scope: removeall cookie rewriter, which will, remove all cookies from replay headers.
  • Security: disable file:// altogether for live rewrite path.
  • Fuzzy match: better support for custom replace string >1 character: leave string, and strip remainder before fuzzy query.
  • Urlrewriter and wburl fixes for various corner cases.
  • Rangecache: use url as key if digest not present.
  • Framed replay: attempt to mitigate chrome OS X scrolling issue by disabling -webkit-transform: none in framed mode. Improves scrolling on many pages but not always consistent (a chrome bug).

pywb 0.9.3 changelist

  • framed replay mode: support framed_replay: inverse where the top frame is the canonical archival url and the inner frame has mp_ modifier.
  • wb.js: improved redirect check: only redirect to top frame in framed mode and compare decoded urls.
  • charset detection: read first 1024 bytes to determine charset and add to Content-Type header if no charset is specified there.
  • indexing: support indexing of WARC records with urn: values as target uris, such as those created by wpull
  • remove certauth module: now using standalone certauth package.
  • BlockLoader: use requests instead of urllib2.
  • cdx: %-encode any non-ascii chars found in cdx fields.
  • cdx: showNumPages query always return valid result (not 404) for 0 pages. If <1 block, load cdx to determine if 1 page or none.

pywb 0.9.2 changelist

  • Collections Manager: Allow adding any templates to shared directory, fix adding WARCs with relative path.
  • Replay: Remove limit by HTTP Content-Length as it may be invalid (only using the record length).
  • WARC Revisit-Resolution Improvements: Support indexes and warcs without any digest field. If no digest is found, attempt to look up the original WARC record from the WARC-Refers-To-Target-URI and WARC-Refers-To-Date only, even for same url revisits. (Previously, only used this lookup original url was different from revisit url)

pywb 0.9.1 changelist

  • Implement pagination support for zipnum cluster and added to cdx server api:

    https://github.com/ikreymer/pywb/wiki/CDX-Server-API

  • cdx server query: add support for url=*.host and url=host/* as shortcuts for matchType=domain and matchType=prefix

  • zipnum cdx cluster: support loading index shared from prefix path instead of seperate location file.

    The shard_index_loc config property may contain match and replace properties. Regex replacement is then used to obtain path prefix from the shard prefix path.

  • wombat: fix document.write() rewriting to rewrite each element at a time and use underlying write for better compatibility.

pywb 0.9.0 changelist

  • New directory-based configuration-less init system! config.yaml no longer required.

  • New wb-manager collection manager for adding warcs, indexing, adding/removing templates, setting metadata.

    More details at: Auto-Configuration and Wayback Collections Manager

  • Support for user metadata via per-collection metadata.yaml
  • Templates: improved/simpified home page and collection search page, show user metadata by default.
  • Support for writing and reading new cdx JSON format (.cdxj), with searchable key followed by json dictionary: urlkey timestamp { ... } on each line
  • cdx-indexer -j: support for generating cdxj format

  • cdx-indexer -mj: support for minimal cdx format (in JSON format) only which skips reading the HTTP record.

    Fields included in minimal format are: urlkey, timestamp, original url, record length, digest, offset, and filename

  • cdx-indexer --root-dir <dir>: option for custom root dir for cdx filenames to be relative to this directory.
  • wb-manager cdx-convert: option to convert any existing cdx to new cdxj format, including ensuring cdx key is in SURT canonicalized.
  • wb-manager autoindex / wayback -a -- Support for auto-updating the cdx indexes whenever any WARC/ARC files are modified or created.

  • Switch default wayback, cdx-server, live-rewrite-server cli apps to use waitress WSGI container instead of wsgi ref.

    New cli options, including -p (port), -t (num threads), and -d (working directory)

  • url rewrite: fixes to JS url rewrite (some urls with unencoded chars were not being rewritten), fixes to WbUrl parsing of urls starting with digits (eg. 1234.example.com) not being parsed properly.
  • framed replay: update frame_insert.html to be html5 compliant.
  • wombat: fixed to WB_wombat_location.href assignment, properly redirects to dest page even if url is already rewritten
  • static paths: static content included with pywb moved from static/default -> static/__pywb to free up default as possible collection name and avoid any naming conflicts. For example, wombat.js can be accessed via /static/__pywb/wombat.js
  • default to replay with framed mode enabled: framed_replay: true

pywb 0.8.3 changelist

  • cookie rewrite: all cookie rewriters remove secure flag to allow equivalent replay of sites with cookies via HTTP and HTTPS.

  • html rewrite: fix <base> tag rewriting to add a trailing slash to the url if it is a hostname with no path, ex:

    <base href="http://example.com" /> -> <base href="http://localhost:8080/rewrite/http://example.com/" />

  • framed replay: fix double slash that remainded when rewriting top frame url.

pywb 0.8.2 changelist

  • rewrite: fix for redirect loop related to pages with 'www.' prefix. Since canonicalization removes the prefix, treat redirect to 'www.' as self-redirect (for now).
  • memento: ensure rel=memento url matches timegate redirect exactly (urls may differ due to canonicalization, use actual instead of requested for both)

pywb 0.8.1 changelist

  • wb.js top frame notification: use window.__orig_parent when referencing actual parent as window.parent now overriden.
  • live proxy security: enable ssl verification for live proxy by default, for use with python 2.7.9 ssl improvements. Was disabled due to incomplete ssl support in previous versions of python. Can be disabled via verify_ssl: False per collection.
  • cdx-indexer: add recursive option to index warcs in all subdirectories with cdx-indexer -r <dir_name>

pywb 0.8.0 changelist

Improvements to framed replay, memento support, IDN urls, and additional customization support in preparation for further config changes.

  • Feature: Full support for 'non-exact' or sticky timestamp browsing in framed and non-framed mode.
    • setting redir_to_exact: False (per collection), no redirects will be issued to the exact timestamp of the capture. The user-specified timestamp will be preserved and the number of redirects will be reduced.
    • if no timestamp is present (latest-replay request), there is a redirect to the current time UTC timestamp, available via pywb.utils.timeutils.timestamp_now() function.
    • via head-insert, the exact request timestamp is provided as wbinfo.request_ts and accessible to the banner insert or the top frame when in framed mode.
  • Frame Mode Replay Improvements, including:
    • wombat: modify window.parent and window.frameElement to hide top-level non replay frame.
    • memento improvements: add same memento headers to top-level frame to match replay frame to ensure top-level frame passes memento header validation.
    • frame mode uses the request timestamp instead of the capture timestamp to update frame url. By default, request timestamp == capture timestamp, unless redir_to_exact: False (see above).
  • Client-Side Rewrite Improvements:
    • improved document.write override to also work when in <head> and append both <head> and <body>
    • detect multiple calls to rewrite attribute to avoid rewrite loops.
  • Customization improvements:
    • ability to override global UrlRewriter with custom class by setting urlrewriter_class config setting.
    • ability to disable JS url and location rewrite via js_rewrite_location: none setting.
    • ability to set a custom content loader in place of default ARC/WARC loader in ReplayView._init_replay_view
  • Improved Memento compatibility, ensuring all responses have a rel=memento link.
  • IDN support: Improved handling of non-ascii domains.
    • all urls are internally converted to a Punycode host, percent encoded path using IDNA encoding (http://tools.ietf.org/html/rfc3490.html).
    • when rendering, return convert all urls to fully percent-encoded by default (to allow browser to convert to unicode characters).
    • punycode_links rewrite option can be enabled to keep ascii-punycode hostnames instead of percent-encoding.

pywb 0.7.2 changelist

  • Experiment with disabling DASH for YT

  • New req_cookie_rewrite rewrite directive to rewrite outgoing Cookie header, can be used to fix a certain cookie for a url prefix.

    A list of regex match/replace rules, applied in succession, can be set for each url prefix. See rules.yaml for more info.

pywb 0.7.1 changelist

  • (0.7.1 fixes some missing static files from 0.7.0 release)

  • Video/Audio Replay, Live Proxy and Recording Support (with pywb-webrecorder)!

    See: Video Replay and Recording for more detailed info.

  • Support for replaying HTTP/1.1 range requests for any archived resorce (optional range cache be disabled via enable_ranges: false)

  • Support for on-the-fly video replacement of Flash with HTML5 using new video rewrite system vidrw.js.

    (Designed for all Flash videos, with varying levels of special cases for YouTube, Vimeo, Soundcloud and Dailymotion)

  • Use youtube-dl to find actual video streams from page urls, record video info.
  • New, improved wombat 2.1 -- improved rewriting of dynamic content, including:

    • Image() object override
    • ability to disable dynamic attribute rewriting by setting _no_rewrite on an element.
  • Type detection: resolve conflict between text/html that is served under js mod, resolve if html or js.

pywb 0.6.6 changelist

  • JS client side improvements: check for double-inits, preserve anchor in wb.js top location redirect

  • JS Rewriters: add mixins for link + location (default), link only, location only rewriting by setting js_rewrite_location to all, urls, location, respectively.

    (New: location only rewriting does not change JS urls)

  • Beginning of new rewrite options, settable per collections and stored in UrlRewriter. Available options:
    • rewrite_base - set to False to disable rewriting <base href="..."> tag
    • rewrite_rel_canon - set to false to disable rewriting <link rel=canon href="...">
  • JS rewrite: Don't rewrite location if starting with '$'

pywb 0.6.5 changelist

  • fix static handling when content type can not be guessed, default to 'application/octet-stream'
  • rewrite fix: understand partially encoded urls such as http%3A// in WbUrl, decode correctly
  • rewrite fix: rewrite //example.com and \/\/example.com in JS same as \example.com
  • cookies: add exact cookie rewriter which sets cookie to exact url only, never collection or host root
  • don't rewrite rel=canonical links for services which rely on these
  • cdx-indexer: Detect non-gzip chunk encoded .warc.gz/arc.gz archive files and show a meaningful error message explaining how to fix issue (uncompress and possibly use warctools warc2warc to recompress)

pywb 0.6.4 changelist

  • Ignore bad multiline headers in warc.
  • Rewrite fix: Don't parse html entities in HTML rewriter.
  • Ensure cdx iterator closed when reeading.
  • Rewrite fix: remove pywb prefix from any query params.
  • Rewrite fix: better JS rewriting, avoid // comments when matching protocol-relative urls.
  • WARC metadata and resource records include in cdx from cdx-indexer by default

pywb 0.6.3 changelist

  • Minor fixes for extensability and support https://webrecorder.io, easier to override any request (handle_request), handle_replay or handle_query via WBHandler

pywb 0.6.2 changelist

  • Invert framed replay paradigm: Canonical page is always without a modifier (instead of with mp_), if using frames, the page redirects to tf_, and uses replaceState() to change url back to canonical form.
  • Enable Memento support for framed replay, include Memento headers in top frame

  • Easier to customize just the banner html, via banner_html setting in the config. Default banner uses ui/banner.html and inserts the script default_banner.js, which creates the banner.

    Other implementations may create banner via custom JS or directly insert HTML, as needed. Setting banner_html: False will disable the banner.

  • Small improvements to streaming response, read in fixed chunks to allow better streaming from live.

  • Improved cookie and csrf-token rewriting, including: ability to set cookie_scope: root per collection to have all replayed cookies have their Path set to application root.

    This is useful for replaying sites which share cookies amongst different pages and across archived time ranges.

  • New, implified notation for fuzzy match rules on query params (See: Fuzzy Match Rules)

pywb 0.6.0 changelist

  • HTTPS Proxy Support! (See: Proxy Mode Usage)
  • Revamped HTTP/S system: proxy collection and capture time switching via cookie!
  • removed hostnames setting in config.yaml. pywb no longer needs to know the host(s) it is running on, can infer the correct path from referrer on a fallback handling.
  • remove PAC config, just using direct proxy (HTTP and HTTPS) for simplicity.

pywb 0.5.4 changelist

  • bug fix: self-redirect check resolves relative Location: redirects
  • rewrite rules: 'parse_comments' option to parse html comments as JS, regex rewrite update to match '&quot;http:\\/' double backslash
  • bug fixes in framed replay for html content, update top frame for html content on load when possible

pywb 0.5.3 changelist

  • better framed replay for non-html content -- include live rewrite timestamp via temp 'pywb.timestamp' cookie, updating banner of iframe load. All timestamp formatting moved to client-side for better customization.
  • refactoring of replay/live handlers for better extensability.
  • banner-only rewrite mode (via 'bn' modifier) to support only banner insertion with no rewriting, server-side or client-side.

pywb 0.5.1 changelist

minor fixes:

  • cdxindexer accepts unicode filenames, encodes via sys encoding
  • SCRIPT_NAME now defaults to '' if not present

pywb 0.5.0 changelist

  • Catch live rewrite errors and display more friendly pywb error message.
  • LiveRewriteHandler and WBHandler refactoring: LiveRewriteHandler now supports a root search page html template.
  • Proxy mode option: 'unaltered_replay' to proxy archival data with no modifications (no banner, no server or client side rewriting).
  • Fix client side rewriting (wombat.js) for proxy mode: only rewrite https -> http in absolute urls.
  • Fixes to memento timemap/timegate to work with framed replay mode.

  • Support for a fallback handler which will be called from a replay handler instead of a 404 response.

    The handler, specified via the fallback option, can be the name of any other replay handler. Typically, it can be used with a live rewrite handler to fetch missing content from live instead of showing a 404.

  • Live Rewrite can now be included as a 'collection type' in a pywb deployment by setting index path to $liveweb.
  • live-rewrite-server has optional --proxy host:port param to specify a loading live web data through an HTTP/S proxy, such as for use with a recording proxy.
  • wombat: add document.cookie -> document.WB_wombat_cookie rewriting to check and rewrite Path= to archival url
  • Better parent relative '../' path rewriting, resolved to correct absolute urls when rewritten. Additional testing for parent relative urls.
  • New 'proxy_options' block, including 'use_default_coll' to allow defaulting to first collection w/o proxy auth.
  • Improved support for proxy mode, allow different collections to be selected via proxy auth

pywb 0.4.7 changelist

  • Tests: Additional testing of bad cdx lines, missing revisit records.
  • Rewrite: Removal of lxml support for now, as it leads to problematic replay and not much performance improvements.
  • Rewrite: Parsing of html as raw bytes instead of decode/encode, detection still needed for non-ascii compatible encoding.
  • Indexing: Refactoring of cdx-indexer using a seperate 'archive record iterator' and pluggable cdx writer classes. Groundwork for creating custom indexers.
  • Indexing: Support for 9 field cdx formats with -9 flag.
  • Rewrite: Improved top -> WB_wombat_top rewriting.
  • Rewrite: Better handling of framed replay url notification

pywb 0.4.5 changelist

  • Support for framed or non-framed mode replay, toggleable via the framed_replay flag in the config.yaml
  • Cookie rewriter: remove Max-Age to use ensure session-expiry instead of long-term cookie (experimental).
  • Live Rewrite: proxy all headers, instead of a whitelist.
  • Fixes to <base> tag handling, now correctly rewriting remainder of urls with the set base.
  • cdx-indexer options for resolving POST requests, and indexing request records. (-p and -a)
  • Improved POST request replay, allowing for improved replay of many captures relying on POST requests.

pywb 0.4.0 changelist

  • Improved test coverage throughout the project.
  • live-rewrite-server: A new web server for checking rewriting rules against live content. A white-list of request headers is sent to the destination server. See rewrite_live.py for more details.
  • Cookie Rewriting in Archival Mode: HTTP Set-Cookie header rewritten to remove Expires, rewrite Path and Domain. If Domain is used, Path is set to / to ensure cookie is visible from all archival urls.
  • Much improved handling of chunk encoded responses, better handling of zero-length chunks and fix bug where not enough gzip data was read for a full chunk to be decoded. Support for chunk-decoding w/o gzip decompression (for example, for binary data).
  • Redis CDX: Initial support for reading entire CDX 'file' from a redis key via ZRANGEBYLEX, though needs more testing.
  • Jinja templates: additional keyword args added to most templates for customization, export 'urlsplit' to use by templates.
  • Remove SeekableLineReader, just using standard file-like object for binary search.
  • Proper handling of js cs modifiers to select content-type.
  • New, experimental support for top-level 'frame mode', used by live-rewrite-server, to display rewritten content in a frame. The mp modifier is used to indicate the main page when top-level page is a frame.
  • cdx-indexer: Support for creation of non-SURT, url-ordered as well SURT-ordered CDX files.
  • Further rewrite of wombat.js: support for window.open, postMessage overrides, additional rewriting at Node creation time, better hash change detection. Use Object.defineProperty whenever possible to better override assignment to various JS properties. See wombat.js for more info.
  • Update wombat.js to support: scheme-relative urls rewriting, dom manipulation rewriting, disable web Worker api which could leak to live requests
  • Fixed support for empty arc/warc records. Indexed with '-', replay with '204 No Content'
  • Improve lxml rewriting, letting lxml handle parsing and decoding from bytestream directly (to address #36)

pywb 0.3.0 changelist

  • Generate cdx indexs via command-line cdx-indexer script. Optionally sorting, and output to either a single combined file or a file per-directory. Refer to cdx-indexer -h for more info.
  • Initial support for prefix url queries, eg: http://localhost:8080/pywb/\*/http://example.com\* to query all captures from http://example.com
  • Support for optional LXML html-based parser for fastest possible parsing. If lxml is installed on the system and via pip install lxml, lxml parser is enabled by default. (This can be turned off by setting use_lxml_parser: false in the config)
  • Full support for Memento Protocol RFC7089 Memento, TimeGate and TimeMaps. Memento: TimeMaps in application/link-format provided via the /timemap/*/ query.. eg: http://localhost:8080/pywb/timemap/\*/http://example.com
  • pywb now features new domain-specific rules which are applied to resolve and render certain difficult and dynamic content, in order to make accurate web replay work. This ruleset will be under further iteration to address further challenges as the web evoles.
