CHANGES

Revision history for Sys::SigAction.

Changes in Sys::SigAction 0.15 1 Jul 2011

Clean up POD. Close bug #69057. Other minor tweaks to POD.

Changes in Sys::SigAction 0.13 23 Jun 2011

No functional changes. Fix for test timeout.t. Fix strict undefined symbol error in timeout.t, when Time::HiRes is not present. Not sure if constant pragma will exist in all supported perl versions, so, we just commented out the use strict in this test.

Print warning when Time::HiRes not found in Makefile.PL

Changes in Sys::SigAction 0.12 20 Jun 2011

Conditionally add 'LICENSE' => 'perl' to WriteMakefile() call if $ExtUtils::MakeMaker::VERSION >= 6.3002.

Added support for timeout_call() in fractional seconds expressed as a floating point number. If Time::HiRes is not loadable, then the timeout value is raised to the next high integer value with the POSIX:ceil() funtion.

Added sig_alarm(), which timeout_call uses. This is drop in replacement for alarm(). If Time::HiRes is not loadable, then the seconds argument is raised to the next high integer value with the POSIX:ceil() funtion.

Update sample code to use double evals in response

https://rt.cpan.org/Public/Bug/Display.html?id=50628

The bug author wrote:

Suppose the eval dies for some reason unrelated to the signal handling
just before the alarm expires, and then the code exits the eval, and
then the alarm expires before the final alarm(0) can be called. Now
either the code will completely die because there is no SIGALRM
handler in place to catch the signal, or the wrong handler (not the
local handler) will be called.

Make the same change in timeout_call(). The change traps the remote possibility that an alarm signal could arrive between the time code dies (for some unrelated reason) and the final eval is called or called.

Changes in Sys::SigAction 0.11 31 Jan 2009

Remove Restriction in License which required permission to include in CDROM media for commercial distribution.

License is now Straight GPL or Artistic as Perl is.

Fix safe attribute for perl >= 5.8.2, but applying patch in (duplicate) bugs:

http://rt.cpan.org/Ticket/Display.html?id=39599
http://rt.cpan.org/Ticket/Display.html?id=39946

Test by cloning mask.t into safe.t in the block for perl => 5.008002 and test setting safe attribute. Sadly, using both masked signals and safe=>1 at the same time, is still broken.

Add checks for unsupported configurations in Makefile.PL to (hopefully) suppress the Smoke test failures for those environments.

Update documentation.

Documentation cleanup, thanks to Tim Maher.

Changes in Sys::SigAction 0.09 17 Oct 2006

Francesco has pointed out that I still have a special case of safe=>0 broken for perl 5.8.0.

The perl 5.8.1 build I tested with (I could not find 5.8.0) it turns out has .../lib/5.8.1/auto/POSIX/SigAction/safe.al, my previous tests works.

This version of Sys::SigAction now as a test of these subtleties in t/safe.t, those still no real test of safe=>1 for perls >= 5.8.2

Changes in Sys::SigAction 0.08 11 Oct 2006

Add extra protection to test of $attrs->(safe} when the perl version is between 5.8 and 5.8.2, thanks to Francesco Duranti. Now test for it being defined before testing it's value. It would be a pretty bizarre case for that to happen, but... belt and suspenders... is 'safe'.

Fix warning in safe.t which referred to attrs.t (old test name) which was renamed to mask.t, to refer to mask.t.

Changes in Sys::SigAction 0.07 09 Oct 2006

Version 0.06 broke in perl < 5.8.2... (who uses that any more!!!) Well someone does... at least on RedHat... I did (do) claim backwards compatibility... So I fixed it right this time, by checking the perl version before called the safe accessor on the POSIX::SigAction object.

Still no good test for safe mode... be prepared to send me a test if you think safe signal handling is broken... for sure I could not get it to work the way I think it should with with deferred signals.

Changes in Sys::SigAction 0.06 25 June 2006

Fix setting of SAFE flag in POSIX::sigaction. In response to CPAN bug: http://rt.cpan.org/Ticket/Display.html?id=19916 Thanks to Steve Purk?, for point this out.

This required NOT setting safe=>1 (changing to to safe=>0) in t/attrs.t and the the dbd-oracle test script.

A new test for safe=>1 needs to be developed, which explicitly tests deferred signal handling. I would welcome such a contribution.

Fix typo in POD for mask => thanks to Henri Asseily This was apparently never uploaded. :-(

Lincoln A Baxter

Changes in Sys::SigAction 0.04 7 April 2004

Modify forever() in timeout.t so just loop instead of trying to read from STDIN, which apparently does not block or immediately returns an error on some platforms or test environments

Lincoln A Baxter ck =head2 Changes in Sys::SigAction 0.03 4 April 2004

Skip attrs.t test if perl version < 5.8.2 (rt.cpan.org ticket #5948)

Rename dbd-oracle-timout.PL -> dbd-oracle-timeout.POD

Changes in Sys::SigAction 0.02 3 February 2004

Comment out 'use warnings' for $] < 5.006

Suppress undefined warning in destructor for $] < 5.008

Documentation expansion and cleanup

Add dbd-oracle-timeout.PL
