Revision history for Perl extension Time::HiRes.
1.47
- do not use -lrt in Linux (from March Lehmann)
- unnecessary (nanosleep is in libc anyway)
- harmful (-lrt slows down execution)
- incompatible (with many distributions' pthreads)
1.46
- do not create files in blib directories under core
(perl change #19160, from rgs)
- detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd)
1.45
- guarantee that $xdefine in HiRes.t is always defined
(perl change #19109, from IlyaZ)
- a cleaner way to detect PERL_CORE (perl change #19111,
from IlyaZ)
1.44
- add hints/irix.pl to turn off overly POSIX flags that
cause hide struct timespec to be hidden (and compilation
to fail) (bleadperl change #19085)
- documentation tweaks
1.43
- add c:/temp to the list of temp directories to probe
so that cygwin (and win*?) builds are happy. This was
needed at least in my cygwin 1.3.20/w2k setup.
1.42
- modernize the constants code (from Nicholas Clark)
1.41
- At some point the ability to figure our the correct incdir
for EXTERN.h (either a core perl build, or an installed perl)
had broken (which lead into all test compiles failing with
a core perl build, but thanks to the robustness of Makefile.PL
nothing of this was visible). The brokenness seemed to be
caused by $ENV{PERL_CORE} not being on for core builds?
Now stole a trick from the Encode that sets $ENV{PERL_CORE}
right, and both styles of build should work again.
1.40
- Nicholas Clark noticed that the my_catdir() emulation function
was broken (which means that we didn't really work for Perls
5.002 and 5.003)
- inspired by fixing the above made the whole Makefile.PL -w
and strict clean
- tightened up the Makefile.PL output, less whitespace
1.39
- fix from Craig Berry for better building in VMS with PERL_CORE
1.38
- no functional changes
- move lib/Time/HiRes.pm as Hires.pm
- libraries scanning was slightly broken (always scanned
for a library even when $Config{libs} already had it)
1.37
- Ray Zimmerman ran into a race condition in Mac OS X.
A 0.01-second alarm fired before the test expected.
The test first slept indefinitely (blocking for signals)
and only after that tested for the signal having been sent.
Since the signal had already been sent, the test #12 never
completed. The solution: test first, then block.
- default to being silent on all probing attempts, set the
environment variable VERBOSE to a true value to see the
details (the probing command and the possible errors)
1.36
- do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski)
- INSTALLDIRS => 'perl' missing which means that Time::HiRes
cannot be upgraded from CPAN to override the 5.8.0 version
(Guido A. Ostkamp)
- Time::HiRes 1.35 could not be dropped as-is to bleadperl
because the include directories did not adjust themselves
if $ENV{PERL_CORE} (Hugo van der Sanden)
- add documentation about the restart of select() under alarm()
1.35
- small documentation tweaks
1.34
- better VMS operation (Craig Berry)
1.33
- our time machine is accelerating: now works with Perl 5.004_01
(tried with 5.003_07 and 5.002 but I get segmentation faults
from running the Makefile.PL with those in Tru64 4.0D)
1.32
- backward compatibility (pre-5.6.0) tweaks:
- no XSLoader in 5.00503, use DynaLoader instead
- no SvPV_nolen, either
- no PerlProc_pause(), either
- now tested with 5.00404 and 5.00503
- Makefile.PL requires 5.00404 (no more 5.002)
- use nanosleep instead of usleep, if it is available (Wilson Snyder)
(this means that one can mix subsecond sleeps with alarms)
- because of nanosleep we probe for -lrt and -lposix4
- the existence of getitimer/nanosleep/setitimer/ualarm/usleep
is available by exportable constants Time::HiRes::d_func
(since older Perl do not have them in %Config, and even
5.8.0 does not probe for nanosleep)
1.31
- backward compatibility (pre-5.6.1) tweaks:
- define NV if no NVTYPE
- define IVdf if needed (note: the Devel::PPPort
in 5.8.0 does not try hard hard enough since
the IVSIZE might not be defined)
- define NVgf if needed
- grab the typemap from 5.8.0 for the NV stuff
1.30
- release 1.29_02 as 1.30
1.29_02
- fix a silly unclosed comment typo in HiRes.xs
- document and export REALTIME_REALPROF (Solaris)
1.29_01
- only getitimer(ITIMER_REAL) available in Cygwin and Win32
(need to patch this also in Perl 5.[89])
- remove CVS revision log from HiRes.xs
1.29_00

The following changes were made on top of the changes
made for Time::HiRes during the Perl 5.7 development
cycle that culminated in the release of Perl 5.8.0.
- add "require 5.005" to the Makefile.PL
- remove the REVISION section (CVS log) from HiRes.pm
- add jhi's copyright alongside Douglas'
- move HiRes.pm to lib/Time/
- move HiRes.t to t/
- modify HiRes.t to use $ENV{PERL_CORE}
- modify the original Time::HiRes version 1.20 Makefile.PL
to work both with Perl 5.8.0 and the new code with pre-5.8.0
Perls (tried with 5.6.1)
- tiny tweaks and updates in README and TODO
- bump the VERSION to 1.29
1.20 Wed Feb 24 21:30 1999
- make our usleep and ualarm substitutes into hrt_usleep
and hrt_ualarm. This helps static links of Perl with other
packages that also have usleep, etc. From
Ilya Zakharevich <ilya@math.ohio-state.edu>
- add C API stuff. From Joshua Pritikin
<joshua.pritikin@db.com>
- VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer)
- hopefully correct "-lc" fix for SCO.
- add PPD stuff
1.19 Tue Sep 29 22:30 1998
- put VMS gettimeofday() in. Patch is from Sebastian Bazley
<seb@stian.demon.co.uk>
- change GIMME_V to GIMME to help people with older versions of
Perl.
- fix Win32 version of gettimeofday(). It didn't affect anything,
but it confuses people reading the code when the return value
is backwards (0 is success).
- fix Makefile.PL (more) so that detection of gettimeofday is
more correct.
1.18 Mon Jul 6 22:40 1998
- add usleep() for Win32.
- fix Makefile.PL to fix reported HP/UX feature where unresolved
externals still cause an executable to be generated (though no
x bit set). Thanks to David Kozinn for report and explanation.
Problems with the fix are mine :)
1.17 Wed Jul 1 20:10 1998
- fix setitimer calls so microseconds is not more than 1000000.
Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD.
- make Win32. We only get gettimeofday (the select hack doesn't
seem to work on my Win95 system).
- fix test 4 on 01test.t. add test to see if time() and
Time::HiRes::time() are close.
1.16 Wed Nov 12 21:05 1997
- add missing EXTEND in new gettimeofday scalar code.
1.15 Mon Nov 10 21:30 1997
- HiRes.pm: update pod. Provided by Gisle Aas.
- HiRes.xs: if gettimeofday() called in scalar context, do
something more useful than before. Provided by Gisle Aas.
- README: tell of xsubpp '-nolinenumber' woes. thanks to
Edward Henigin <ed@texas.net> for pointing out the problem.
1.14 Wed Nov 5 9:40 1997
- Makefile.PL: look for setitimer
- HiRes.xs: if missing ualarm, but we have setitimer, make up
our own setitimer. These were provided by Gisle Aas.
1.13 Tue Nov 4 23:30 1997
- Makefile.PL: fix autodetect mechanism to do try linking in addition
to just compiling; should fix Linux build problem. Fix was provided
by Gisle Aas.
1.12 Sun Oct 12 12:00:00 1997
- Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug;
you may need to comment this back out if you have an older xsubpp.
- HiRes.xs: set PROTOTYPES: DISABLE
1.11 Fri Sep 05 16:00:00 1997
- Makefile.PL:
Had some line commented out that shouldn't have been (testing
remnants)
- README:
Previous version was corrupted.
1.10 Thu May 22 20:20:00 1997
- HiRes.xs, HiRes.pm, t/*:
- only compile what we have OS support for (or can
fake with select())
- only test what we compiled
- gross improvement to the test suite
- fix EXPORT_FAIL.
This work was all done by Roderick Schertler
<roderick@argon.org>. If you run Linux or
one of the other ualarm-less platoforms, and you like this
module, let Roderick know; without him, it still wouldn't
be working on those boxes...
- Makefile.PL: figure out what routines the OS has and
only build what we need. These bits were written by Jarkko
Hietaniemi <jhi@iki.fi>. Again, gratitude is due...
1.02 Mon Dec 30 08:00:00 1996
- HiRes.pm: update documentation to say what to do when missing
ualarm() and friends.
- README: update to warn that ualarm() and friends need to exist
1.01 Fri Oct 17 08:00:00 1996
- Makefile.PL: make XSPROTOARGS => '-noprototyopes'
- HiRes.pm: put blank line between __END__ and =head1 so that
pod2man works.
1.00 Tue Sep 03 13:00:00 1996
- original version; created by h2xs 1.16
