cvsanaly   2.1.0
================

This is the CVSAnalY which bring together a lot of commits done during
2009, 2010 and 2011.

Bug fixes:

    * Fix --version command line option
    * [metrics] Fix file extension extraction from paths
    * [metrics] Fix path building in cvs when module is '.'
    * Encode strings to utf-8 before writing to stdout/stderr
    * Fix prefix branch for paths in multi-paths actions. In SVN it's
    possible to copy/move/replace a path from one branch into
    another. In this case the action branch is different from the
    branch of the second path. This usually happens when creating a
    branch:   A /branches/foo (from /trunk: 1234)
    * Remove leading / from path before querying the cache.
    For repositories like git where paths don't start with / we have to
    remove the leading / from the built path before inserting in into
    the cache, but also before querying the cache
    * Fix compatibility in SQL statement LIMIT.
    The previous declaration of the LIMIT statement in the class
    ICursor is incompatible with Postgresql.  However, both SQLite
    and MySQL supports the statement LIMIT ... OFFSET which also
    support Postgresql.
    * Fix SQL portability issue in view action_files.
    The syntax used when the view action_files is created is not
    compatible with Postgresql, which requires the clause 'AS' when
    an alias is defined.  The clause 'AS' is optional in MySQL and
    SQLite. Fixes bug #28.
    * Add conditional use of args when executing a query.
    SQLite cursor's does not handle extra parameters in a query that
    does not have paraments.  Instead of passing None, it should not
    pass any argument at all.  Fix Bug #30.
    * [git] Fix a crash when there's a commit in a svn tag. Fixes #75
    * [cvs] Remove additional trailing \n added to commit messages.
    Problem spotted by David Gray.
    * Fixes incorrect licence header in most of the files. Fixes #240
    * [extensions] Missing self before class attribute. Fixes #248

New features:

    * Add a flag command line option to ignore errors in metrics
    extension
    * Add ICursor class to split up queries.
    The result of a query is always stored in memory, which means that
    queries that return a large amount of data might fill up the
    memory.
    ICursor is a class that uses a real cursor emulating the execute +
    fetchmany API, but splitting up the query by using limit, so that
    the query is executed with different limit values everytime a
    fetchmany is required.
    * [extensions] Add Blame extension.
    It adds a new table with information about the amount of lines
    owned by every author of every file for every revision
    * [extensions] Add Patches extension to save diffs of changes.
    It adds a new table to store the patch of every commit
    * Add a configuration sample file. Fixes bug #27

Performance fixes and improvements:

    * Do not save caches to disk on every database commit since it's a
    very heavy operation, it is done only once at the end of the
    parsing process
    * Paths in different branches are now considered as different
    files. That was obvious with SVN because branches are directories,
    but in CVS and Git exactly the same path can be in different
    branches.
    * Use cat instead of checkout/update to get the contents of files
    in metrics extension. Multiple cat commands can run in parallel
    which improves performance quite a lot.
    * Proccess finished jobs every 100 jobs to make sure there are jobs
    in the done queue and removing the timeout the first time
    job_pool.get_next_done is called to make sure we always get a job.
    * Update the adjacency matrix sequentially instead of re-create it
    for every revision. It drastically improves the performance of the
    Metrics extension
    * Add debug messages to git parser
    * [git] Rework git parser to save memory with large repos
    * [metrics] Remove unnecessary code
    * Add get_filename() to FilePaths to get just the file name of a
    given file_id
    * Detect and ignore empty branches in git
    * [git] Ignore commits done on svn tags directory. This is a
    workaround for a bug in the GNOME Git migration
    * DBContentHandler.py refactored
    * Do not call DBContentHandler methods until proxy has finished.
    DBContentHandler creates a database connection in begin() and
    keeps it opened until proxy finishes. For repos with a very long
    history it might take a long time until proxy finishes and mysql
    resets the connection of the DBContentHandler because of
    inactivity timeout.
    * Improved Debian files

Documentation:

    * Rename ChangeLog to ChangeLog.pre-git and autogenerate it
    * Improved README file

cvsanaly   2.0.0
================

This is the final CVSAnalY 2.0 release.

Bug fixes:

    * Include man page and other documentation files in the dist
      tarball. (Thanks to Víctor Llorens Vilella for reporting)

Documentation:

    * First version of the user manual

================
cvsanaly 1.99.91
================

This the last beta release of cvsanaly2. Next releases (release
candidates and final release) will only contain bug fixes and
documentation updates.

Database Schema Changes:

    * commit_id has been removed from the file_types table.
    * A new view (action_files) has been added to be able to match the
      file_id associated to the action independently of the action
      type. This is needed because in a replace action might involve 3
      files: the file being replaced, the new file replacing the
      old one and the file from which the replacement is done. In
      these cases the new file is not stored in the actions table, but
      in the to_id field of file_copies table. This view is almost a
      copy of the actions table but the file_id will be taken from
      file_copies for replace actions. 

New Features:

    * Add a command line option (-n, --no-parse) to be able to skip
      the parsing process when used in conjunction with --extensions
    * Add git support in Metrics extension
    * Use a persistent cache on disk to store the caches used in
      DBContentHandler. This makes running CVSAnalY incrementally
      finally work
    * Store -1 values in the database instead of NULL when the file
      failed to be measured, so that it can be tried again in a
      another CVSAnalY execution. NULL values are now reserved for the
      files that are not supported.
    * Try again up to 3 times when a checkout/update fails, just in
      case it's just a short temporary network problem, in Metrics
      extension
    * Use the Command.py module in Metrics extension which provides
      better error handling
    * Instead of a single config file a directory is used now to store
      the config file and the state of the caches used in
      DBContentHandler needed to incrmentally run CVSAnalY. The old
      configuration is automatically migrated. 
    * Subsets of repositories can be analyzed and treated as
      individual repositories. Specially useful to analyze SVN
      repositorires with 'modules'

Performance Fixes and Improvements:

    * All queries have been reviewed and optimized
    * CommitsLOC extension has been reworked, so that for CVS and Git
      repositories we extract the information from the log command
      instead of running diffs which drastically improves the
      performance. 
    * Do not run executemany if we don't have any data to insert in
      FileTypes and CommitsLOC extensions
    * Do not find te same program in PATH more than once in Metrics
      extension
    * Split the temp_log query into several queries to save memory
    * Use a maximum size in queues, blocking on put() when the queue
      is full, in order to save memory

Documentation:

    * Add documentation in texi format. Not finished yet.
    * Update the manpage

Bug Fixes:

    * Remove the tempdir used in Metrics extension when the extension
      is aborted 
    * Do not use deprecated python stuff
    * Fix infinite loop in DBContentHandler when a path has been
      renamed several times to the same name
    * Do not crash when the Metrics extension doesn't support the
      repository type, raise an exception instead. 
    * Fix a crash with repositories where paths don't start with '/' 
    * Fix the main queries used in FileTypes and Metrics extensions by
      using the new action_files view to make sure we always get the
      right file_id.
    * Fix incosistency issues between the cache used in
      DBContentandler and the database
    * Several fixes in the SVN parser.

================
cvsanaly 1.99.90
================

This is the first relase of cvsanaly2 (2.0.0-beta1), a complete rework
of CVSAnalY. 

New Features:

    * Support for MySQL and SQLite, althought MySQL is the recommended
      one (and default option) because it gives better
      performance. SQLite is recommended for debuging or for small
      projects. 
    * Improved file handling. The whole history is stored in the
      repository so that the files tree can be rebuilt for any
      given revision. It's possible to get the path of any file at any
      given revision even if it (or any of its parents) has been moved
      or renamed.
    * Committer and Author fields for systems like git and bzr that
      differenciate between them.
    * Option to save the logfile into a local path while parsing.
    * Tags and branches support.
    * Additional information not contained in the repository log can
      be optionally added to the database by using extensions. At the
      moment there are three extensions available: FileTypes,
      CommitsLOC and Metrics.
    * Multiple repositories can be analyzed using a single database.
    * New database design which fits much better with all source code
      management systems.
    * Configuration file support.
    * New code design, more efficient and extensible.
    * Better performance, it's quite faster performing the whole
      analysis proccess.
    * New and improved log parsers with support for CVS, SVN and
      Git. There's also a preliminary Bazaar support.
