ANNOUNCE: Beagle 0.2.8

[Joe Shaw <joeshaw novell com>]

Hi,

I'm happy to announce the release of Beagle 0.2.8.

We have been very active since our 0.2.7 release in June.  This
version has many new features, including a Thunderbird backend,
wildcard searches, and the ability to suspend indexing while on
battery.  Moreover, as of this release, the Beagle daemon and its
command-line tools no longer require gtk-sharp (only glib-sharp).
Many bugs have also been fixed, including issues searching for HTML
mails, case-sensitivity bugs when searching for certain properties,
problems opening files and emails containing certain Unicode
characters, and overaggressive optimizing of indexes.  We encourage
everyone to try out this release.

WHAT IS BEAGLE?
---------------
 
Beagle is a tool for indexing and searching your data.  Beagle is
improving rapidly on many fronts, and should work well enough for
everyday use.
 
The Beagle daemon transparently monitors your data and updates the
index to reflect any changes.  On an inotify-enabled system, these
updates happen more-or-less in real time.  So for example,
 
* Files are immediately indexed when they are created, are re-indexed
  when they are modified, and are dropped from the index upon deletion.
* E-mails are indexed upon arrival.
* IM conversations are indexed as you chat, a line at a time.

Beagle supports many different file formats including OpenOffice
documents, Microsoft Word documents, PDFs, HTML files, and many image,
audio and video formats.  Beagle can extract information from your
file system; Evolution, Thunderbird, and KMail emails; Evolution and
Thunderbird addressbooks; Evolution calendars; Gaim and Kopete instant
messenger conversations; feeds from several RSS aggregators; Tomboy
notes; Konqueror browsing history; system documentation; and many
others.  Beagle also indexes tags on your photos from F-Spot and
Digikam.

Beagle also provides Firefox and Epiphany extensions that index web
pages in real-time as the user visits them.

Beagle uses the Lucene indexing system from the prodigious Doug
Cutting.

Beagle includes a GTK-based graphical tool for searching the index
that the daemon creates.  This application doesn't query the index
directly; it passes the search terms to the daemon and the daemon
sends any matches back.  The user interface then renders the results
and allows you to perform useful actions on the matching objects.

Indexing your data requires a fair amount of computing power, but the
Beagle daemon tries to be as unobtrusive as possible.  It contains a
scheduler that works to prioritize tasks and control CPU usage, based
on whether or not you are actively using your workstation.


DEPENDENCY HECK
---------------

Beagle requires:
* Mono 1.1.13.5 or better, along with the full Mono stack
* glib-sharp 2.3.90 or better (for the daemon and tools)
* gtk-sharp 2.3.90 or better (for the UI and some backends)
* GMime 2.1.19
* Libexif 0.5.7 or better
* shared-mime-info

For the best possible Beagle experience, you should also have:
* Mono 1.1.16 or better
* GMime 2.2.1
* Evolution-sharp 0.10.2 or 0.11.1
* libgsf 1.12.1 and gsf-sharp 0.6 or libgsf 1.14 and gsf-sharp 0.7
* Either wv 1.2.0, or a *patched* wv 1.0.3 --- the patch is available from
  http://users.avafan.com/~fredrik/beagle/wv-libole2-readonly.patch
* An inotify-enabled kernel.  Inotify is in the mainline Linux
  kernel as of 2.6.13.

CHANGES SINCE 0.2.7
-------------------

Daemon/Infrastructure:
* No longer require gtk-sharp for the core parts of the daemon and
  tools, only glib-sharp.  (Debajyoti Bera)
* Add support for wildcard searches.  (Joe Shaw)
* Monitor the battery status and stop the scheduler if the config
  option is set.  (Joe)
* Optimize an index no more often than once a day.  (Joe)
* Fix various case-sensitivity issues when searching against
  properties.  (Joe)
* If file attributes were previously stored in the Sqlite database but
  can now be set using extended attributes, do that and remove the old
  one.  (Bera)
* Add messages to retrieve specific daemon information rather than
  getting it all at once.  (Bera)
* Fix a crash in xdgmime in which null mime types were being added to
  the database.  (Bera)
* Better handle errors when hits are filtered by backends.  (Joe)
* Greatly improve error reporting throughout the code.  (Joe, Bera)
* Improve signal handling, especially immediately after daemon
  startup.  (Bera)
* Add a handler for SIGUSR1 to turn on the highest level of debugging
  while the daemon is running.  (Joe)

Backends:
* Added a Thunderbird backend (Pierre Östlund, Kevin Kubasik)
* When crawling the file system, index directories only one level down
  from the root before all others.  (Joe)
* Use more efficient indexable generators for the Gaim and indexing
  service backends, making startup much faster for people with
  thousands of IM logs or viewed web pages.  (Joe)
* Fix various bugs in parsing the Kopete buddy list.  (Pat Double)
* Add some sanity checks to the Evolution mail backend, checking for
  non-existent summary files.  (Joe)
* Fix a file descriptor leak in the KMail backend.  (Joe)

Filters:
* Correctly handle "emotes" in Gaim log files.  (Joe)
* Soft line breaks are correctly treated as whitespace in the
  OpenOffice filter.  (Bera)
* Index the name of individual sheets in an OpenOffice spreadsheet.
  (Bera)
* Don't index style nodes in OpenOffice filter.  (Bera)
* Don't try to index password-protected PowerPoint documents.  (Joe)

  displayed are more accurate.  (Joe)
* Fix amusing bug where you could use the scroll wheel to scroll
  through the different pages at startup.  (Joe)

KNOWN ISSUES
------------

We still use a bit too much memory.  We are working on it.

Certain extremely large documents can temporarily degrade your
system's performance while they are being indexed.

The file system is now much more robust than ever before.  However, there
are still race conditions that can occur with certain combinations of
file system operations.  In some cases it might be necessary to stop and
restart the daemon.

Certain files can crash the underlying libraries Beagle uses to
extract metadata.  This has been observed in MS Word and JPG files.
If you encounter such a crash, please report it to the upstream
developer of those libraries (wv1 and libexif for the above, respectively).

At this point in development, we cannot commit to stable APIs or file formats.
You will almost certainly need to delete your indexes and start again at some
point in the future.
