Revision history for Perl extension File::NFSLock.

1.20 May 13 12:00 2003

• Avoid double reverting signal handlers when unlock() is explicitly called instead of implicitly called from DESTROY().
• Fixed this warning: Argument "DEFAULT" isn't numeric in numeric eq (==)

1.19 Dec 17 23:30 2002

• Minor code cleanup patch by Stephen Waters.

1.18 Jul 25 17:00 2002

• Add newpid() method to handle fork() conditions.

1.17 Jun 10 12:00 2002

• Handle system crash recovery better or other abnormal/abrupt termination (like SIGKILL) conditions more gracefully.

1.16 Jun 05 15:00 2002

• Allow exclusive lock to be obtained on the same file multiple times by the the same process.

1.15 Jun 04 09:00 2002

• Default to catch certain signals to avoid creating stale locks on graceful termination.
• More tests to test signal handlers.
• Fix test t/300_bl_sh.t to measure only what is required.

1.14 Jun 03 12:00 2002

• Add test to exploit unlock bug (fixed by Andy in 1.13)
• Less anal tests for slower platforms (Slowaris) to succeed as well.

1.13 May 30 12:00 2002

• Add spec file for RPM packaging.
• Show example in perldoc using numerical constants.
• Make perldoc example strict clean.
• Add INSTALL section to perldoc.
• Fixed bug that forced a lock aquired by another process to be released when an exclusive lock attempt fails. Patch by andyh@myinternet.com.au (Andy Hird)

1.12 Nov 05 12:00 2001

• Change code to utilize numerical constants instead of the magic strings.
• Change several sub routines into methods of the object to reduce arguments passed.
• Avoid double unlocking (DESTROY).
• Added some nice tests.
• Pulled out stale_lock code to check once at initial lock attempt instead of repeated checks during the blocking lock loop. This may change functionality slightly in that a lock will never "become" stale if it wasn't already stale when the lock attempt initiated.
• Shared lock feature now functional.

1.11 Oct 30 12:00 2001

• (Not released)
• Initial attempt to add shared lock feature.

1.10 Jul 31 10:10 2001

• Allow for numerical constants from Fcntl.
• Return Error status in $errstr.
• Allow for custom lock extensions via $LOCK_EXTENSION.
• Allow for passing parameters as a hashref
• Allow for stale_lock_timeout parameter

1.00 May 24 10:50 2001

• Initial release of File::NFSLock.
• Release under 1.00 tag as this is already in use.
• Blocking and Nonblocking locking is possible.
• uncache routine is available.
