pywb/CHANGES.rst

pywb 0.5.0 changelist
~~~~~~~~~~~~~~~~~~~~~

* 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.

* 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 <https://github.com/ikreymer/pywb/wiki/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 <https://github.com/ikreymer/pywb/blob/master/pywb/rewrite/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 <https://github.com/ikreymer/pywb/blob/master/pywb/static/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 <http://www.mementoweb.org/guide/rfc/>`_ 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 <https://github.com/ikreymer/pywb/blob/master/pywb/rules.yaml>`_ 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.
