Cedar-backup3

* Change mbox extension to use ISO-8601 date format when calling grepmail.
* Fix error-handling in generateTarfile() when target dir is missing.
* Tweak pycheckrc to find fewer expected errors (from standard library).
* Fix Debian bug 403546 by supporting more CD writer configurations.
- Be looser with SCSI "methods" allowed in valid SCSI id (update regex)
- Make <store> config section's <target_scsi_id> parameter optional
- Change CdWriter to support "hardware id" as either SCSI id or device
- Implement cdrecord commands in terms of hardware id instead of SCSI id
- Add documentation in writer.py to discuss how we talk to hardware
- Rework user manual's discussion of how to configure SCSI devices
* Update Cedar Backup user manual.
- Re-order setup procedures to modify cron at end (Debian 403662)
- Fix minor typos and misspellings (Debian 403448 among others)
- Add discussion about proper ordering of extension actions

* Changes to fix, update and properly build Cedar Backup manual
- Change DocBook XSL configuration to use "current" stylesheet
- Tweak manual-generation rules to work around XSL toolchain issues
- Document where to find grepmail utility in Appendix B
- Create missing documentation for mbox exclusions configuration
- Bumped copyright dates to show "(c) 2005-2006" where needed
- Made minor changes to some sections based on proofreading

* Remove outdated comment in xmlutil.py about dependency on PyXML.
* Tweak wording in doc/docbook.txt to make it clearer.
* Consistently rework "project description" everywhere.
* Fix some simple typos in various comments and documentation.
* Added recursive flag (default True) to FilesystemList.addDirContents().
* Added flat flag (default False) to BackupFileList.generateTarfile().
* Created mbox extension in CedarBackup2.extend.mbox (closes: 31).
- Updated user manual to document the new extension and restore process.
* Added PostgreSQL extension in CedarBackup2.extend.postgresql (closes: 32).
- This code was contributed by user Antoine Beaupre ("The Anarcat").
- I tweaked it slightly, added configuration tests, and updated the manual.
- I have no PostgreSQL databases on which to test the functionality.
* Made most unit tests run properly on Windows platform, just for fun.
* Re-implement Pipe class (under executeCommand) for Python 2.4+
- After Python 2.4, cross-platform subprocess.Popen class is available
- Added some new regression tests for executeCommand to stress new Pipe
* Switch to newer version of Docbook XSL stylesheet (1.68.1)
- The old stylesheet isn't easily available any more (gone from sf.net)
- Unfortunately, the PDF output changed somewhat with the new version
* Add support for collecting individual files (closes: 30).
- Create new config.CollectFile class for use by other classes
- Update config.CollectConfig class to contain a list of collect files
- Update config.Config class to parse and emit collect file data
- Modified collect process in action.py to handle collect files
- Updated user manual to discuss new <file> configuraton

* Remove some bogus writer tests that depended on an arbitrary SCSI device.

* Tweak the CREDITS file to fix a few typos.
* Remove completed tasks in TODO file and reorganize it slightly.
* Get rid of sys.exit() calls in util/test.py in favor of simple returns.
* Fix implementation of BackupFileList.removeUnchanged(captureDigest=True).
- Since version 2.7.0, digest only included backed-up (unchanged) files
- This release fixes code so digest is captured for all files in the list
- Fixed captureDigest test cases, which were testing for wrong results
* Make some more updates to the user manual based on further proof-reading.
- Rework description of "midnight boundary" warning slightly in basic.xml
- Change "Which Linux Distribution?" to "Which Platform?" in config.xml
- Fix a few typos and misspellings in basic.xml

* Cleanup some maintainer-only (non-distributed) Makefile rules.
* Make changes to standardize file headers with other Cedar Solutions code.
* Add debug statements to filesystem code (huge increase in debug log size).
* Standardize some config variable names ("parentNode" instead of "parent").
* Fix util/test.py to return proper (non-zero) return status upon failure.
* No longer attempt to change ownership of files when not running as root.
* Remove regression test for bug 25 (testAddFile_036) 'cause it's not portable.
* Modify use of user/password in MySQL extension (suggested by Matthias Urlichs).
- Make user and password values optional in Cedar Backup configuration
- Add a few regression tests to make sure configuration changes work
- Add warning when user or password value(s) are visible in process listing
- Document use of /root/.my.cnf or ~/.my.cnf in source code and user manual
- Rework discussion of command line, file permissions, etc. in user manual
* Optimize incremental backup, and hopefully speed it up a bit (closes: 29).
- Change BackupFileList.removeUnchanged() to accept a captureDigest flag
- This avoids need to call both generateDigestMap() and removeUnchanged()
- Note that interface to removeUnchanged was modified, but not broken
* Add support for pre- and post-action command hooks (closes: 27).
- Added <pre_action_hook> and <post_action_hook> sections within <options>
- Updated user manual documentation for options configuration section
- Create new config.PreActionHook and PostActionHook classes to hold hooks
- Added new hooks list field on config.OptionsConfig class
- Update ActionSet and ActionItem in cli to handle and execute hooks
* Rework and abstract XML functionality, plus remove dependency on PyXML.
- Refactor general XML utility code out of config.py into xmlutil.py
- Create new isElement() function to eliminate need for Node references
- Create new createInputDom(), createOutputDom() and serializeDom() functions
- Use minidom XML parser rather than PyExpat.reader (much faster)
- Hack together xmlutil.Serializer based on xml.dom.ext.PrettyPrint
- Remove references to PyXML in manual's depends.xml and install.xml files
- Add notes about PyXML code sourced from Fourthought, Inc. in CREDITS
- Rework mysql and subversion unit tests in terms of new functions
