All these moves are needed because - - 1) one cannot directly do eval 'Time::HiRes::FOO_BAR' - because FOO_BAR might have a true value of zero - (or in the general case an empty string or even undef) - - 2) In case FOO_BAR is not available in this platform, - &FOO_BAR avoids the bareword warning - - - wait more (1.5 seconds instead of 0.1) for the CLOCK_REALTIME test - but expect the 'customary' slop of 0.20 instead of 0.25 - - fixed inside a comment HAS_POLL -> TIME_HIRES_NANOSLEEP - - at the end of HiRest.t tell how close we were to termination - -1.80 [2005-11-04] - - Gisle noticed a mistake (using HAS_NANOSLEEP) in 1.79 - -1.79 [2005-11-03] - - try nanosleep for emulating usleep -- may help in some weird - embedded realtime places which have nanosleep but neither usleep - nor select nor poll (doesn't have to be weird embedded realtime - place, though -- in many places usleep is nanosleep anyway) - - try poll for emulating usleep -- this may help some obscure/old - SVR4 places that have neither usleep nor select - - a redundant test guard in HiRes.t - -1.78 [2005-11-03] - - ITIMER_VIRTUAL detection in HiRes.t had problems (that we cannot - in the general case fail already at 'use' phase is suboptimal) - - fixes to the documentation of clock_gettime() and clock_getres() - -1.77 [2005-11-03] - - add support for the POSIX clock_gettime() and clock_getres(), - if available, either as library calls or as syscalls - - be more defensive about missing functionality: break out - early (during 'use') if no e.g. clock_getres() is available, - and protect our back by trapping those cases also in HiRes.xs - - the test added in 1.76 could cause an endless loop e.g. in Solaris, - due to mixing of sleep() and alarm() (bad programmer, no cookie!) - -1.76 [2005-10-22] - - testing for nanosleep had wrong logic which caused nanosleep - to become undefined for e.g. Mac OS X - - added a test for a core dump that was introduced by Perl 5.8.0 - safe signals and was fixed for the time of 5.8.1 (one report of - the core dump was [perl #20920]), the test skipped pre-5.8.1. - - *cough* s/unanosleep/nanosleep/g; *cough* - -1.75 [2005-10-18] - - installation patch from Gisle Aas: in Perls 5.8.x and later - use MakeMaker INSTALLDIRS value of 'perl' instead of 'site'. - -1.74 [2005-09-19] - - [cpan #14608] Solaris 8 perl 5.005_03 File::Spec module does not have method rel2abs - (the workaround is not to use rel2abs, should not be necessary) - - [cpan #14642] U2time wrongly exported on the C API - (patch supplied by the reporter, SALVA@cpan.org) - - add release dates to Changes - -1.73 [2005-08-16] - - Time::HiRes::nanosleep support for Solaris [PATCH] - (POSIX::uname() not available if building with core perl, - from Gisle Aas, via perl5-porters, perl change #25295) - -1.72 [2005-07-01] - - going back to the 1.68 loader setup (using DynaLoader) - since too many weird things starting breaking - - fix a typo in José Auguste-Etienne's name - -1.71 [2005-06-28] - - a thinko in the nanosleep() detection - - move more changes stuff from the README to Changes - - add -w to the Makefile.PL - -1.70 [2005-06-26] - - oops in 1.69 about @ISA (not affecting anything but silly) - - add copyright 2005 to HiRes.pm - - add copyright and license to HiRes.xs - - add copyrights 2003, 2004, 2005 to README - -1.69 [2005-06-25] - - actually run a test for nanosleep - (if there is no $Config{d_nanosleep}) since e.g. in AIX 4.2 - it seems that one can link in nanosleep() but then calling - it fails instantly and sets errno to ENOSYS (Not implemented). - This may be fixable in the AIX case by figuring out the right - (realtime POSIX?) libs and whatnot, but in the general case - running a real test case is better. (Of course, this change - will no doubt run into portability problems because of the - execution step...) Note that because of hysterical raisins - most Perls do NOT have $Config{d_nanosleep} (scanning for - it by Configure would in many platforms require linking in - things like -lrt, which would in many platforms be a bad idea - for Perl itself). - (from José Auguste-Etienne) - - support XSLoader also since it's much faster - (from Alexey Tourbin) - - add SEE ALSO (BSD::Resource and Time::TAI64) - -1.68 [2005-05-14] - - somehow 1.67 had a lot of doubled lines (a major cut-and-paste - error suspected), but miraculously it still worked since the - doubling took place below the __END__ token - - undef Pause() before defining it to avoid redefinition warnings - during compilation in case perl.h had already defined Pause() - (part of perl change #24271) - - minor doc tweaks - -1.67 [2005-05-04] - - (internal) don't ignore the return value of gettimeofday() - - (external) return undef or an empty if the C gettimeofday() fails - (affects Time::HiRes gettimeofday() and the hires time()) - -1.66 [2004-12-19] - - add nanosleep() - - fix the 'hierachy' typo in Makefile.PL [rt.cpan.org #8492] - - should now build in Solaris [rt.cpan.org #7165] (since 1.64) - - should now build in Cygwin [rt.cpan.org #7535] (since 1.64) - - close also [rt.cpan.org #5933] "Time::HiRes::time does not - pick up time adjustments like ntp" since ever reproducing it - (and therefore verifying a possible fix) in the same environment - has become rather unlikely - -1.65 [2004-09-18] - - one should not mix u?alarm and sleep (the tests modified - by 1.65, #12 and #13, hung in Solaris), now we just busy - loop executing an empty block - - in the documentation underline the unspecificity of mixing - sleeps and alarms - - small spelling fixes - -1.64 [2004-09-16] - - regenerate ppport.h with Devel::PPPort 3.03, - now the MY_CXT_CLONE is defined in ppport.h, - we no more need to do that. - - - the test #12 would often hang in sigsuspend() (at least that's - where Mac OS X' ktrace shows it hanging). With the sleep()s - changed to sleep(1)s, the tests still pass but no hang after - a few hundred repeats. - -1.63 [2004-09-01] - - Win32 and any ithread build: ppport.h didn't define - MY_CXT_CLONE, which seems to be a Time-HiRes-ism. - -1.62 [2004-08-31] - - Skip testing if under PERL_CORE and Time::HiRes has not - been Configured (from Marcus Holland-Moritz, core change - #23246) - - Use ppport.h generated by Devel::PPPort 3.01, - allowing cutting away our own portability code. - - Don't use $ENV{PERL_CORE} for < 5.6.0. - - Don't use "for my $i" for <= 5.003. - - Don't use Pause() for <= 5.003. - - Can't use newSVpvf for <= 5.003. - (most of the changes from Marcus) - -1.61 [2004-08-21] - - Win32: reset reading from the performance counters every - five minutes to better track wall clock time (thanks to - PC timers being often quite bad), should help long-running - programs. - -1.60 [2004-08-15] - - Win32: Patch from Steve Hay - [PATCH] Re: [perl #30755] [Win32] Different results from Time::HiRes::gettimeofdayunder the debugger - to [perl #30755] reported by Nigel Sandever - - - Cygwin: Use the Win32 recalibration code also in Cygwin if the - <w32api/windows.h> APIs are available.

Hedden. - -1.56 [2004-29-02] - - Give a clearer message if the tests timeout (perl change #22253) - - Don't use /tmp or its moral equivalents (perl bug #15036, - perl change #22258) - -1.55 [2004-01-14] - - Windows: mingw32 patch from Mike Pomraning (use Perl's Const64() - instead of VC-specific i64 suffix) - -1.54 [2003-12-31] - - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep - -1.53 [2003-12-30] - - Windows: higher resolution time() by using the Windows - performance counter API, from Jan Dubois and Anton Shcherbinin. - The exact new higher resolution depends on the hardware, - but it should be quite a bit better than using the basic - Windows timers. - -1.52 [2003-10-28] - - In AIX (v?) with perl 5.6.1 the HiRes.t can hang after - the subtest 18. No known analysis nor fix, but added - an alarm (that requires fork() and alarm()) to the test. - -1.51 [2003-09-22] - - doc tweaks from mjd (perl change #20456) - - NCR MP-RAS hints file added (svr4.pl) (perl change #21249) - -1.50 [2003-08-02] - - add a message (for non-core builds) to Makefile.PL about - the LC_ALL=C workaround - - &Time::HiRes::d_nanosleep was broken (perl change #20131) - - the nanosleep() probe was broken (perl change #20061) - - use existence instead of definedness for feature probes - (perl change #20043) - - MPE/iX tweak (perl change #20042) - - do not use HAS_NANOSLEEP (perl change #19898) - -1.49 [2003-06-23] - - UVuf for non-IVSIZE platforms (from Keiichiro Nagano) - - OS/2 can always mix subsecond sleeps with signals - (part of perl change #19789) - -1.48 [2003-06-04] - - workaround for buggy gcc 2.95.3 in openbsd/sparc64 - (perl change #19592) - -1.47 [2003-05-03] - - do not use -lrt in Linux (from March Lehmann, perl change #19449) - - unnecessary (nanosleep is in libc anyway) - - harmful (-lrt slows down execution) - - incompatible (with many distributions' pthreads) - -1.46 [2003-04-25] - - 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 [2003-04-01] - - 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 [2003-03-30] - - 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 [2003-03-11] - - 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 [2003-01-07] - - modernize the constants code (from Nicholas Clark) - -1.41 [2003-01-03] - - 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 [2003-01-03] - - 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 [2003-10-20] - - fix from Craig Berry for better building in VMS with PERL_CORE - -1.38 [2003-10-13] - - 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 [2003-09-23] - - 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 [2003-09-12] - - 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 [2003-08-24] - - small documentation tweaks - - -1.34 [2003-08-22] - - better VMS operation (Craig Berry) - -1.33 [2003-08-20] - - 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 [2003-08-20] - - 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 [2003-08-19] - - 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 - - 1.31 and 1.32 add more backward compatibility (now all the way - back to Perl 5.00404), and using nanosleep() (if available) for - subsecond sleeps. - -1.30 [2003-08-16] - - - release 1.29_02 as 1.30 - - 1.30 adds all the changes made during the Perl 5.6->5.7->5.8 - development cycle. Most notably portability across platforms has been - enhanced, and the interval timers (setitimer, getitimer) have been - added. Note that the version of Time::HiRes that is included in Perl - 5.8.0 calls itself 1.20_00, but it is equivalent to this Time::HiRes - version. Note also that in 1.30 Wegscheid turns over the maintenance - to Jarkko Hietaniemi. - -1.29_02 [2003-08-16] - - - fix a silly unclosed comment typo in HiRes.xs - - document and export REALTIME_REALPROF (Solaris) - -1.29_01 [2003-08-16] - - - 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 [2003-08-14] - - The following numbered patches refer to the Perl 5.7 changes, - you can browse them at http://public.activestate.com/cgi-bin/perlbrowse - - - 17558: Add #!./perl to the .t - - 17201: linux + usemorebits fix, from Rafael Garcia-Suarez - - 16198: political correctness, from Simon Cozens - - 15857: doc tweaks, from Jarkko Hietaniemi - - 15593: optimization in .xs, from Paul Green - - 14892: pod fixes, from Robin Barker - - 14100: VOS fixes, from Paul Green - - 13422: XS segfault, from Marc Lehmann - - 13378: whether select() gets restarted on signals, depends - - 13354: timing constraints, again, from Andy Dougherty - - 13278: can't do subsecond alarms with ualarm; - break out early if alarms do not seem to be working - - 13266: test relaxation (cygwin gets lower hires - times than lores ones) - - 12846: protect against high load, from Jarkko Hietaniemi - - 12837: HiRes.t VMS tweak, from Craig A.

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 - - 1.20 adds a platform neutral set of C accessible routines if you are - running 5.005+. All other changes are packaging changes and build - fixes(?) for statically linked Perl, SCO, and VMS. - -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. - - 1.19 has better VMS support. - -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 :) - - 1.18 has limited Win32 support (no ualarm). Added usleep for Win32. - Probably buggy. I'm sure I'll hear. - -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. - - 1.16+ should be closer to building out of the box on Linux. Thanks - to Gisle Aas for patches, and the ualarm equivalent using setitimer. - - If your underlying operating system doesn't implement ualarm(), then - a fake using setitimer() will be made. If the OS is missing usleep(), - a fake one using select() will be made. If a fake can't be made for - either ualarm() or usleep(), then the corresponding Perl function will - not be available. If the OS is missing gettimeofday(), you will get - unresolved externals, either at link- or run-time. - - This is an improvement; the package used to not even build if - you were missing any of these bits. Roderick Schertler - - <roderick@argon.org> did all the conditional compilation stuff, - look at HiRes.pm and the test suites; it's good educational reading. - -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 platforms, 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 |
