1Revision history for the Perl extension Time::HiRes. 2 3{{NEXT}} 4 5 - Remove obsolete vms code 6 - Use core version compare 7 - Use GIMME_V instead of the deprecated GIMME 8 - t/utime.t: dragonflybsd has only microsecond precision 9 - t/utime.t: dragonflybsd is noatime by default 10 - t/stat.t: skip testing access times on HaikuOS, it doesn't support 11 atime 12 - darwin: make sure the compiler can find the system perl headers 13 https://github.com/Perl/perl5/issues/20362 14 - darwin: make sure PERL_DARWIN is defined on darwin. 15 - don't compare stat and lstat atime if PERL_FILE_ATIME_CHANGES is set in 16 the environment. 17 https://github.com/Perl/perl5/issues/19321 18 - don't use C++ guards around the perl header files, it caused C++ 19 build failures with MSVC. 20 - don't try to suppress C++ compatibility warnings in C++ builds, since 21 that warns. 22 231.9764 [2020-08-10] 24 - Fix a bunch of repeated-word typos 25 - Fix compilation with Visual C++ 2013 and older 26 - Implement clock_gettime() and clock_getres() for win32 27 - Remove workaround for an ancient Devel::PPPort bug 28 - Remove the remains of MacOS classic support 29 - Remove code for perls older than 5.6 30 - Remove vestiges of mpeix support (removed in 5.17.x) 31 - Remove trailing blanks 32 - Add links to pod 33 341.9760 [2019-02-18] 35 - make utime() available only if we have both fd and name setting 36 [RT #133030] 37 - Adjutst Makefile.PL for windows: the DEFINE() in Makefile.PL 38 can't be in sub init() because that sub isn't called on windows 39 - t/itimer.t: avoid race condition. 40 - don't truncate nanosec utime 41 - fallback/const-c.inc: Avoid compiler warning showing up on darwin. 42 431.9759 [2018-03-23] 44 - This version reverts the changes on CPAN that were included in 1.9754 - 1.9758. 45 Several of these changes caused instability on some windows platforms. We can 46 revisit these fixes if necessary in Perl 5.29.0 47 481.9758 [2018-03-21] 49 - fix build in Win32 with Visual C by introducing a fake struct timezone 50 [rt.cpan.org #124844] 51 - in utime.t detect better being run in a noatime filesystem, 52 and if so, skip the test (for the HAMMER filesystem of DragonflyBSD) 53 - also for the HAMMER fs (if not in noatime), lower the expected subsecond 54 timestamp granularity to microseconds 55 - fix the version number typo in Changes: 1.9577 -> 1.9757 56 571.9757 [2018-03-15] 58 - fix win32 (and cygwin?) builds which have been broken since 1.9755: 59 problem was that gettimeofday() is a macro and needs to stay such 60 - regenerate ppport.h with Perl 5.26.1 (was previously generated with 61 5.25.6) and Devel::PPPort 3.35 (previously 3.36) -- this doesn't 62 change the ppport.h, though 63 641.9756 [2018-03-14] 65 - division by zero in new test tv_interval.t [rt.cpan.org #124775]: 66 made the test pass even if the difference is zero, but also 67 made it practically impossible to ever be zero by adding 68 a sub-second sleep. 69 - remove comments from inside qw [rt.cpan.org #124777], 70 only seemed to be caught by Perl 5.18.4 71 721.9755 [2018-03-14] 73 - adjust the error messages of tv_interval() 74 - the NV_1EX constants now cast to be NV so that 75 tv_interval() with long double builds does not 76 produce ugly results [rt.cpan.org #106456] 77 - add tests for tv_interval() 78 - centralize the mygettimeofday() logic 79 - make the mygettimeofday() a function instead of macro 80 - add the OS X 10.12+ clock_gettime() constants 81 CLOCK_MONOTONIC_RAW_APPROX CLOCK_UPTIME_RAW_APPROX 82 - regenerate the fallback files 83 841.9754 [2018-02-16] 85 - unify the gettimeofday() and time() forked code 86 that had near identical code paths for MacOS Classic 87 (which has two unusual features: unsigned time_t, 88 and a special tz struct member), and for non-MacOS Classic 89 - tv_interval should be implemented in XS 90 [rt.cpan.org #106456] 91 thanks to Sergey Aleynikov (suggested implementation simplified 92 by the above-mentioned MacOS Classic simplification) 93 941.9753 [2018-01-11] 95 - in t/clock.t in a fast system we need to burn more CPU, 96 reported and fix suggested by Joel C. Maslak <jmaslak@antelope.net> 97 [rt.cpan.org #124025] 98 - for t/utime.t in netbsd we need /sbin in PATH to find the mount command, 99 this is needed for the fix in 1.9751 to actually help netbsd with noatime 100 mounts. 101 (thanks to Nigel Horne) 102 1031.9752 [2018-01-04] 104 - fix an error in the error message of utimensat() not available: 105 it said futimens() not available 106 - add --force alias for Makefile.PL --configure 107 1081.9751 [2018-01-02] 109 - in macOS/OSX/Darwin, use __has_builtin() check also for utimensat(), 110 can cause errors like 111 "HiRes.xs:1474:16: error: unrecognized platform name macOS" 112 [rt.cpan.org #123994] 113 (oversight from 1.9749) 114 - do not define TIME_HIRES_STAT/d_hires_stat if none was found, instead 115 of defining it to be zero, which case has no implementation in hrstatns() 116 (thanks to Nigel Horne) 117 - in t/utime.t try to divine if the filesystem of the tempfiles has been 118 mounted with the 'noatime' option, which can prohibit updating the 119 access time timestamp. Also document this in HiRes.pm. 120 (thanks to Nigel Horne, original analysis by Slaven Rezic) 121 - synchronize the constant lists in HiRes.pm:@EXPORT_OK 122 and Makefile.PL:doConstants and regenerate fallback/const-c.inc 123 and fallback/const-xs.inc, this fixes Perl 5.6.2 issue with 124 d_futimens not allegedly being a valid macro in t/utime.t 125 (using Perl 5.26.1 for the regenerating, not 5.6.2) 126 (thanks to Nigel Horne) 127 - in t/utime.t define a nop sub done_testing for ancient Perls 128 (like Perl 5.6.2) 129 - in Perl 5.6.2 a bogus warning 130 "Use of uninitialized value in subroutine entry" 131 is issued from t/alarm.t: add a comment documenting that 132 1331.9750 [2017-12-22] 134 - update META.yml and META.json for XSLoader instead of DynaLoader 135 [rt.cpan.org #123933] 136 1371.9749 [2017-12-21] 138 - CPAN release 139 - Quieten Time-HiRes test noise: blead 0f009486 140 - Switch some core modules to XSLoader: blead b9a5a78f [rt.cpan.org #129789] 141 - disable a flapping test for CI: blead cd2a978d 142 - Avoid newGVgen in blead-upstream modules: blead 732d3893 143 - Declaration after statement in typemap: blead d269f586 144 - semicolon-friendly diagnostic control: blead 7347ee54 145 - in macOS (OS X) check properly in runtime whether futimens() 146 and utimensat() are available 147 1481.9748 [2017-12-16] 149 - bleadperl only 150 - semicolon-friendly diagnostic control: blead 7347ee54 151 1521.9747 [2017-09-13] 153 - bleadperl only 154 - Switch some core modules to XSLoader: blead b9a5a78f [rt.cpan.org #129789] 155 1561.9746 [2017-08-17] 157 - Unreliable t/usleep.t and t/utime.t tests [rt.cpan.org #122819] 158 Avoid testing for $dt = $t2 - $t1 and assuming $dt is less than 159 some value since a heavily loaded machine can delay the $t2. 160 Testing for greater than is fine. 161 - Tweak the configuring messages about subsecond stat/utime. 162 1631.9745 [2017-08-14] 164 - Properly check for futimens/utimensat actually doing something. 165 This should handle 'gnukfreebsd' (which has only stubs, so far 166 we have been skipping the test) and as a new thing 'gnu' (Hurd) 167 (also only stubs). Thanks to Nigel Horne. 168 - Scan in t/utime.t whether the filesystem (wherever File::Temp 169 puts it tempfiles) supports subsecond timestamps. This removes 170 the fragile Linux/ext3 specific hack. As a side effect, the 171 setting of subsecond timestamps is tested only if reading of 172 them is supported. Thanks to Carsten Gaebler for the test idea, 173 and Ryan Voots for testing. 174 1751.9744 [2017-07-27] 176 - add more potential clock constants, like CLOCK_MONOTONIC_FAST 177 (available in FreeBSD), and not all potentially found clock 178 constants were properly exported to be available from Perl, 179 see your system's clock_gettime() documentation for the available ones 180 1811.9743 [2017-07-20] 182 - correct declared minimum Perl version (should be 5.6, was declared 183 as 5.8 since 1.9727_03): blead af94b3ac 184 - fix the fix for 'do file' to load hints in Makefile.PL: blead 3172fdbc 185 1861.9742 [2017-04-16] 187 - prefer 3-argument open: blead 1ae6ead9 188 - fix dist/Time-HiRes/t/*.t that assumed '.' in @INC: blead 465db51d 189 - fix cases where 'do file' should be 'do ./file'.: blead 8b69401c 190 1911.9741 [2016-11-20] 192 - C++11 compatibility: blead a914236c 193 - El Capitan compatibility: blead 45bbc013 194 - use CLOCK_REALTIME for clock_nanosleep scan: blead 56ed632c 195 - include file consistency in scans: blead 605b4dbe 196 - use clockid_t consistently: blead 2979fdf3 197 - use hv_fetchs(): blead 07e4dd7a 198 - scan for clockid_t (needed for macos Sierra): blead 69d1f2c2 199 - darwin lacks clockid_t: blead d1e7b5aa 200 [rt.cpan.org #129789] 201 - provide template for tempfile: blead 91dca83e 202 - explicit cast for clockid_t in C++11: blead 1c566547 203 - upgrade to a newer ppport (3.35) 204 2051.9740 [2016-09-25] 206 - the ext3/ext2 filesystems do not have subsecond resolution, 207 therefore skip the t/utime.t test 208 [rt.cpan.org #116127] 209 2101.9739 [2016-06-28] 211 - the upcoming macOS 10.12 (Sierra, the operating system formerly 212 known as OS X, or Darwin) has implemented the clock_gettime() 213 and clock_getres() interfaces but not the clock_nanosleep() 214 2151.9738 [2016-06-26] 216 - fix the dates in the Changes, it's not July yet 217 [rt.cpan.org #115553] 218 - in cygwin, drop the utime.t expected timestamp resolution 219 - documented for utime that the actual timestamp resolution depends 220 on the operating system and the filesystem, just like for stat 221 - looks like in gnukfreebsd 10.1 neither futimens or utimensat work 222 even though they exist, skipping utime tests there for now 223 - demodernize the Test::More use in utime.t (no subtest) to 224 better support older Perl installations 225 - for all the tests, drop the Test::More 0.82 requirement, 226 the only "modern" thing used is the note routine which 227 can be replaced with print("# ...\n") (or printf), 228 with this works back at least with Test::More 0.54 (perl 5.8.7) 229 2301.9737 [2016-06-22] 231 - utime in HiRes.xs had dXSARGS which was unnecessary, leading 232 to two markstack pops, panic, and two-minute wait for the watchdog 233 (thanks to Dave Mitchell for the eagle-eye) 234 - even though 5.10.x should have the Perl_ck_warner, many CPAN 235 smokes proved otherwise, so requiring now at least 5.12 for 236 Perl_ck_warner use in IS_SAFE_PATHNAME() 237 2381.9736 [2016-06-22] 239 - the IS_SAFE_PATHNAME() emulation was too modern for Perl 5.10 240 - make it so that only one value is set for -DTIME_HIRES_STAT 241 even on systems that support many options 242 - the 1.9734 (only released in blead, and as part of the development 243 release 5.25.2) fix for Darwin's clock_gettime was wrong under 244 threaded builds, leading into mutex panics in clock.t 245 - the d_hires_utime determination was made more precise 246 - the utime.t was failing in platforms where only one of 247 futimens/utimensat was present (neither or both was okay) 248 2491.9735 [2016-06-20] 250 - Time::HiRes should override `utime` to allow setting hires 251 (futimens and utimensat support) 252 [rt.perl.org #114809] 253 - the utime patch used IS_SAFE_PATHNAME() which isn't available in 254 too old Perls, so emulate (in case the Devel::PPPort is too old) 255 2561.9734 [2016-06-17] 257 - fix Darwins with clock_gettime: blead 2d41a263 258 [rt.perl.org #128427] 259 2601.9733 [2016-04-23] 261 - C90 declaration-after-statement error with darwin threads: blead de1003b4 262 [rt.cpan.org #113856] 263 2641.9732 [2016-03-13] 265 - MUTEX_LOCK, not PERL_MUTEX_LOCK: blead e5b02b5d 266 - also hrt_ualarm_itimer() is unused: 1cb6cce3 267 - the mutex needs init: 2d639e20 268 - version bump to 1.9732: 730d7fdc 269 2701.9731 [2016-03-13] 271 - mark unused variable as such: blead a914236c 272 - OS X emulation mutex accidentally unused: da7a6455 273 - remove hrt_ualarm: 6da77c36 274 - pod error fixes: 919ca095 275 - nanosleep and clock_nanosleep cleanups: c8ea02b8..e3ff671b 276 - static funcs in HiRes.xs: 4e922c26 277 - Remove unused variable: 52ffb1b5 278 2791.9730 [2016-02-17] 280 - TIME_HIRES_DONT_RUN_PROBES=1 to build the probes but not run them 281 [rt.cpan.org #111391] 282 2831.9729 [2016-02-13] 284 - new constants 285 [rt.cpan.org #111170] 286 - clock_getres(), clock_gettime(), clock_nanosleep() emulation for OS X 287 [rt.cpan.org #78566] 288 2891.9728 [2015-11-13] 290 - No changes since 1.9727_03 291 2921.9727_03 [2015-11-06] 293 - use PERL_UNUSED_ARG() in the not-here-croak branches 294 - Makefile.PL/metadata improvements 295 2961.9727_02 [2015-08-29] 297 - correct documentation to note that Time::NVtime is NV, not double 298 [perl #123879] 299 - avoid a warning about clock_t on OS X / clang 3.6 - 3.6 300 [rt.cpan.org #102718] 301 3021.9727_01 [2015-08-17] 303 - Remove usage of 5.005 thread APIs in favor of 5.6 and up thread APIs 304 [rt.cpan.org #102799]. 305 - Silence a C++ compiler warning [rt.cpan.org #101497]. 306 - respect $Config{run} for cross-compiling [rt.cpan.org #92607] 307 3081.9726 [2013-08-17] 309 - Correct s/us splitting of usleep(1000000) [rt.cpan.org #78266]. 310 - Avoid integer overflow in itimer-based alarm() with large 311 argument [rt.cpan.org #87160]. 312 - Define PERL_NO_INLINE_FUNCTIONS during probe compilations, to 313 avoid false negatives caused by not linking with the perl core. 314 - Be more careful about context in stat(). 315 - Install into "site" directories by default on perl 5.11+ 316 [rt.cpan.org #79797]. 317 - Fix a couple of doc typos [rt.cpan.org #85365]. 318 - Fix function name in a doc example [rt.cpan.org #86318]. 319 - Provide lstat() that yields high-res timestamps, alongside 320 the existing high-res stat() [rt.cpan.org #78732]. 321 3221.9725 [2012-02-01] 323 - Correct stack discipline in stat(), which was screwing up list 324 operations in expressions containing calls to it [rt.cpan.org 325 #72926]. 326 - Add missing OUTPUT sections to the XS code [rt.cpan.org #70930]. 327 - Skip itimer tests on GNU/Hurd, which has the API but lacks 328 the implementation [rt.cpan.org #72754]. 329 - Fix a doubled word in the documentation [rt.cpan.org #72763]. 330 3311.9724 [2011-06-09] 332 - Correct XS parameter list, and therefore prototype, for 333 unimplemented-on-this-platform version of clock_nanosleep() 334 [rt.cpan.org #68700]. 335 - Declare package variables with "our" rather than "use vars". 336 -

Address [rt.cpan.org #54196] alarm and ularm return values are bogus, 368 report and fix from Nicholas Clark 369 3701.9719 [2009-01-04] 371 - As with QNX, Haiku has the API of interval timers but not 372 the implementation (bleadperl change #34630), hence skip 373 the tests, via David Mitchell. 374 3751.9718 [2008-12-31] 376 - .xs code cleanup from Albert Dvornik 377 - in the #39 and #40 do not do us I did, mixing alarm() and 378 sleep(). Now instead spin until enough time has passed. 379 3801.9717 [2008-12-30] 381 - Skip the tests added in 1.9716 (#39, #40) if there's no subsecond 382 alarm capability, like with the older subsecond alarm tests 383 3841.9716 [2008-12-26] 385 - Change documentation to agree with reality: there are 386 no interval timers in Win32. 387 - Address [rt.cpan.org #35899] (problem in subsecond sleeps), 388 add two tests to guard against this problem 389 - Address [rt.cpan.org #36600] 'Division by zero' failure in test suite 390 - Address [rt.cpan.org #37340] [PATCH] Address timer process in test 391 - Address [rt.cpan.org#40311 ] bad implementation of hrt_usleep 392 with TIME_HIRES_NANOSLEEP 393 3941.9715 [2008-04-08] 395 - Silly me: Makefile.PL does need to accept arguments other than mine. 396 Some testing frameworks obviously do this. 397 - Add retrying for tests 34..37, which are the most commonly 398 failing tests.

This is heinous. 640 @EXPORT_OK should be determined at Makefile.PL time. 641 - be more lenient is testing clock_gettime(): allow more slop, 642 and retry up to three times, sleeping a random nap between 643 the retries 644 - human months are one-based (noticed by Anton Berezin) 645 6461.82 [2005-10-06] 647 - CLOCK_REALTIME is an enum value (of the clockid_t enum) 648 in HP-UX (and might be so elsewhere, too), debugged by 649 H.

All these moves are needed because 670 671 1) one cannot directly do eval 'Time::HiRes::FOO_BAR' 672 because FOO_BAR might have a true value of zero 673 (or in the general case an empty string or even undef) 674 675 2) In case FOO_BAR is not available in this platform, 676 &FOO_BAR avoids the bareword warning 677 678 - wait more (1.5 seconds instead of 0.1) for the CLOCK_REALTIME test 679 but expect the 'customary' slop of 0.20 instead of 0.25 680 - fixed inside a comment HAS_POLL -> TIME_HIRES_NANOSLEEP 681 - at the end of HiRest.t tell how close we were to termination 682 6831.80 [2005-11-04] 684 - Gisle noticed a mistake (using HAS_NANOSLEEP) in 1.79 685 6861.79 [2005-11-03] 687 - try nanosleep for emulating usleep -- may help in some weird 688 embedded realtime places which have nanosleep but neither usleep 689 nor select nor poll (doesn't have to be weird embedded realtime 690 place, though -- in many places usleep is nanosleep anyway) 691 - try poll for emulating usleep -- this may help some obscure/old 692 SVR4 places that have neither usleep nor select 693 - a redundant test guard in HiRes.t 694 6951.78 [2005-11-03] 696 - ITIMER_VIRTUAL detection in HiRes.t had problems (that we cannot 697 in the general case fail already at 'use' phase is suboptimal) 698 - fixes to the documentation of clock_gettime() and clock_getres() 699 7001.77 [2005-11-03] 701 - add support for the POSIX clock_gettime() and clock_getres(), 702 if available, either as library calls or as syscalls 703 - be more defensive about missing functionality: break out 704 early (during 'use') if no e.g. clock_getres() is available, 705 and protect our back by trapping those cases also in HiRes.xs 706 - the test added in 1.76 could cause an endless loop e.g. in Solaris, 707 due to mixing of sleep() and alarm() (bad programmer, no cookie!) 708 7091.76 [2005-10-22] 710 - testing for nanosleep had wrong logic which caused nanosleep 711 to become undefined for e.g. Mac OS X 712 - added a test for a core dump that was introduced by Perl 5.8.0 713 safe signals and was fixed for the time of 5.8.1 (one report of 714 the core dump was [perl #20920]), the test skipped pre-5.8.1. 715 - *cough* s/unanosleep/nanosleep/g; *cough* 716 7171.75 [2005-10-18] 718 - installation patch from Gisle Aas: in Perls 5.8.x and later 719 use MakeMaker INSTALLDIRS value of 'perl' instead of 'site'. 720 7211.74 [2005-09-19] 722 - [cpan #14608] Solaris 8 perl 5.005_03 File::Spec module does not have method rel2abs 723 (the workaround is not to use rel2abs, should not be necessary) 724 - [cpan #14642] U2time wrongly exported on the C API 725 (patch supplied by the reporter, SALVA@cpan.org) 726 - add release dates to Changes 727 7281.73 [2005-08-16] 729 - Time::HiRes::nanosleep support for Solaris [PATCH] 730 (POSIX::uname() not available if building with core perl, 731 from Gisle Aas, via perl5-porters, perl change #25295) 732 7331.72 [2005-07-01] 734 - going back to the 1.68 loader setup (using DynaLoader) 735 since too many weird things starting breaking 736 - fix a typo in José Auguste-Etienne's name 737 7381.71 [2005-06-28] 739 - a thinko in the nanosleep() detection 740 - move more changes stuff from the README to Changes 741 - add -w to the Makefile.PL 742 7431.70 [2005-06-26] 744 - oops in 1.69 about @ISA (not affecting anything but silly) 745 - add copyright 2005 to HiRes.pm 746 - add copyright and license to HiRes.xs 747 - add copyrights 2003, 2004, 2005 to README 748 7491.69 [2005-06-25] 750 - actually run a test for nanosleep 751 (if there is no $Config{d_nanosleep}) since e.g. in AIX 4.2 752 it seems that one can link in nanosleep() but then calling 753 it fails instantly and sets errno to ENOSYS (Not implemented). 754 This may be fixable in the AIX case by figuring out the right 755 (realtime POSIX?) libs and whatnot, but in the general case 756 running a real test case is better. (Of course, this change 757 will no doubt run into portability problems because of the 758 execution step...) Note that because of hysterical raisins 759 most Perls do NOT have $Config{d_nanosleep} (scanning for 760 it by Configure would in many platforms require linking in 761 things like -lrt, which would in many platforms be a bad idea 762 for Perl itself). 763 (from José Auguste-Etienne) 764 - support XSLoader also since it's much faster 765 (from Alexey Tourbin) 766 - add SEE ALSO (BSD::Resource and Time::TAI64) 767 7681.68 [2005-05-14] 769 - somehow 1.67 had a lot of doubled lines (a major cut-and-paste 770 error suspected), but miraculously it still worked since the 771 doubling took place below the __END__ token 772 - undef Pause() before defining it to avoid redefinition warnings 773 during compilation in case perl.h had already defined Pause() 774 (part of perl change #24271) 775 - minor doc tweaks 776 7771.67 [2005-05-04] 778 - (internal) don't ignore the return value of gettimeofday() 779 - (external) return undef or an empty if the C gettimeofday() fails 780 (affects Time::HiRes gettimeofday() and the hires time()) 781 7821.66 [2004-12-19] 783 - add nanosleep() 784 - fix the 'hierachy' typo in Makefile.PL [rt.cpan.org #8492] 785 - should now build in Solaris [rt.cpan.org #7165] (since 1.64) 786 - should now build in Cygwin [rt.cpan.org #7535] (since 1.64) 787 - close also [rt.cpan.org #5933] "Time::HiRes::time does not 788 pick up time adjustments like ntp" since ever reproducing it 789 (and therefore verifying a possible fix) in the same environment 790 has become rather unlikely 791 7921.65 [2004-09-18] 793 - one should not mix u?alarm and sleep (the tests modified 794 by 1.65, #12 and #13, hung in Solaris), now we just busy 795 loop executing an empty block 796 - in the documentation underline the unspecificity of mixing 797 sleeps and alarms 798 - small spelling fixes 799 8001.64 [2004-09-16] 801 - regenerate ppport.h with Devel::PPPort 3.03, 802 now the MY_CXT_CLONE is defined in ppport.h, 803 we no more need to do that. 804 805 - the test #12 would often hang in sigsuspend() (at least that's 806 where Mac OS X' ktrace shows it hanging). With the sleep()s 807 changed to sleep(1)s, the tests still pass but no hang after 808 a few hundred repeats. 809 8101.63 [2004-09-01] 811 - Win32 and any ithread build: ppport.h didn't define 812 MY_CXT_CLONE, which seems to be a Time-HiRes-ism. 813 8141.62 [2004-08-31] 815 - Skip testing if under PERL_CORE and Time::HiRes has not 816 been Configured (from Marcus Holland-Moritz, core change 817 #23246) 818 - Use ppport.h generated by Devel::PPPort 3.01, 819 allowing cutting away our own portability code. 820 - Don't use $ENV{PERL_CORE} for < 5.6.0. 821 - Don't use "for my $i" for <= 5.003. 822 - Don't use Pause() for <= 5.003. 823 - Can't use newSVpvf for <= 5.003. 824 (most of the changes from Marcus) 825 8261.61 [2004-08-21] 827 - Win32: reset reading from the performance counters every 828 five minutes to better track wall clock time (thanks to 829 PC timers being often quite bad), should help long-running 830 programs. 831 8321.60 [2004-08-15] 833 - Win32: Patch from Steve Hay 834 [PATCH] Re: [perl #30755] [Win32] Different results from Time::HiRes::gettimeofdayunder the debugger 835 to [perl #30755] reported by Nigel Sandever 836 837 - Cygwin: Use the Win32 recalibration code also in Cygwin if the 838 <w32api/windows.h> APIs are available.

Hedden. 859 8601.56 [2004-29-02] 861 - Give a clearer message if the tests timeout (perl change #22253) 862 - Don't use /tmp or its moral equivalents (perl bug #15036, 863 perl change #22258) 864 8651.55 [2004-01-14] 866 - Windows: mingw32 patch from Mike Pomraning (use Perl's Const64() 867 instead of VC-specific i64 suffix) 868 8691.54 [2003-12-31] 870 - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep 871 8721.53 [2003-12-30] 873 - Windows: higher resolution time() by using the Windows 874 performance counter API, from Jan Dubois and Anton Shcherbinin. 875 The exact new higher resolution depends on the hardware, 876 but it should be quite a bit better than using the basic 877 Windows timers. 878 8791.52 [2003-10-28] 880 - In AIX (v?) with perl 5.6.1 the HiRes.t can hang after 881 the subtest 18. No known analysis nor fix, but added 882 an alarm (that requires fork() and alarm()) to the test. 883 8841.51 [2003-09-22] 885 - doc tweaks from mjd (perl change #20456) 886 - NCR MP-RAS hints file added (svr4.pl) (perl change #21249) 887 8881.50 [2003-08-02] 889 - add a message (for non-core builds) to Makefile.PL about 890 the LC_ALL=C workaround 891 - &Time::HiRes::d_nanosleep was broken (perl change #20131) 892 - the nanosleep() probe was broken (perl change #20061) 893 - use existence instead of definedness for feature probes 894 (perl change #20043) 895 - MPE/iX tweak (perl change #20042) 896 - do not use HAS_NANOSLEEP (perl change #19898) 897 8981.49 [2003-06-23] 899 - UVuf for non-IVSIZE platforms (from Keiichiro Nagano) 900 - OS/2 can always mix subsecond sleeps with signals 901 (part of perl change #19789) 902 9031.48 [2003-06-04] 904 - workaround for buggy gcc 2.95.3 in openbsd/sparc64 905 (perl change #19592) 906 9071.47 [2003-05-03] 908 - do not use -lrt in Linux (from March Lehmann, perl change #19449) 909 - unnecessary (nanosleep is in libc anyway) 910 - harmful (-lrt slows down execution) 911 - incompatible (with many distributions' pthreads) 912 9131.46 [2003-04-25] 914 - do not create files in blib directories under core 915 (perl change #19160, from rgs) 916 - detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd) 917 9181.45 [2003-04-01] 919 - guarantee that $xdefine in HiRes.t is always defined 920 (perl change #19109, from IlyaZ) 921 - a cleaner way to detect PERL_CORE (perl change #19111, 922 from IlyaZ) 923 9241.44 [2003-03-30] 925 - add hints/irix.pl to turn off overly POSIX flags that 926 cause hide struct timespec to be hidden (and compilation 927 to fail) (bleadperl change #19085) 928 - documentation tweaks 929 9301.43 [2003-03-11] 931 - add c:/temp to the list of temp directories to probe 932 so that cygwin (and win*?) builds are happy. This was 933 needed at least in my cygwin 1.3.20/w2k setup. 934 9351.42 [2003-01-07] 936 - modernize the constants code (from Nicholas Clark) 937 9381.41 [2003-01-03] 939 - At some point the ability to figure our the correct incdir 940 for EXTERN.h (either a core perl build, or an installed perl) 941 had broken (which lead into all test compiles failing with 942 a core perl build, but thanks to the robustness of Makefile.PL 943 nothing of this was visible). The brokenness seemed to be 944 caused by $ENV{PERL_CORE} not being on for core builds? 945 Now stole a trick from the Encode that sets $ENV{PERL_CORE} 946 right, and both styles of build should work again. 947 9481.40 [2003-01-03] 949 - Nicholas Clark noticed that the my_catdir() emulation function 950 was broken (which means that we didn't really work for Perls 951 5.002 and 5.003) 952 - inspired by fixing the above made the whole Makefile.PL -w 953 and strict clean 954 - tightened up the Makefile.PL output, less whitespace 955 9561.39 [2003-10-20] 957 - fix from Craig Berry for better building in VMS with PERL_CORE 958 9591.38 [2003-10-13] 960 - no functional changes 961 - move lib/Time/HiRes.pm as Hires.pm 962 - libraries scanning was slightly broken (always scanned 963 for a library even when $Config{libs} already had it) 964 9651.37 [2003-09-23] 966 - Ray Zimmerman ran into a race condition in Mac OS X. 967 A 0.01-second alarm fired before the test expected. 968 The test first slept indefinitely (blocking for signals) 969 and only after that tested for the signal having been sent. 970 Since the signal had already been sent, the test #12 never 971 completed. The solution: test first, then block. 972 - default to being silent on all probing attempts, set the 973 environment variable VERBOSE to a true value to see the 974 details (the probing command and the possible errors) 975 9761.36 [2003-09-12] 977 - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski) 978 - INSTALLDIRS => 'perl' missing which means that Time::HiRes 979 cannot be upgraded from CPAN to override the 5.8.0 version 980 (Guido A. Ostkamp) 981 - Time::HiRes 1.35 could not be dropped as-is to bleadperl 982 because the include directories did not adjust themselves 983 if $ENV{PERL_CORE} (Hugo van der Sanden) 984 - add documentation about the restart of select() under alarm() 985 9861.35 [2003-08-24] 987 - small documentation tweaks 988 989 9901.34 [2003-08-22] 991 - better VMS operation (Craig Berry) 992 9931.33 [2003-08-20] 994 - our time machine is accelerating: now works with Perl 5.004_01 995 (tried with 5.003_07 and 5.002 but I get segmentation faults 996 from running the Makefile.PL with those in Tru64 4.0D) 997 9981.32 [2003-08-20] 999 - backward compatibility (pre-5.6.0) tweaks: 1000 - no XSLoader in 5.00503, use DynaLoader instead 1001 - no SvPV_nolen, either 1002 - no PerlProc_pause(), either 1003 - now tested with 5.00404 and 5.00503 1004 - Makefile.PL requires 5.00404 (no more 5.002) 1005 - use nanosleep instead of usleep, if it is available (Wilson Snyder) 1006 (this means that one can mix subsecond sleeps with alarms) 1007 - because of nanosleep we probe for -lrt and -lposix4 1008 - the existence of getitimer/nanosleep/setitimer/ualarm/usleep 1009 is available by exportable constants Time::HiRes::d_func 1010 (since older Perl do not have them in %Config, and even 1011 5.8.0 does not probe for nanosleep) 1012 10131.31 [2003-08-19] 1014 - backward compatibility (pre-5.6.1) tweaks: 1015 - define NV if no NVTYPE 1016 - define IVdf if needed (note: the Devel::PPPort 1017 in 5.8.0 does not try hard enough since 1018 the IVSIZE might not be defined) 1019 - define NVgf if needed 1020 - grab the typemap from 5.8.0 for the NV stuff 1021 1022 1.31 and 1.32 add more backward compatibility (now all the way 1023 back to Perl 5.00404), and using nanosleep() (if available) for 1024 subsecond sleeps. 1025 10261.30 [2003-08-16] 1027 1028 - release 1.29_02 as 1.30 1029 1030 1.30 adds all the changes made during the Perl 5.6->5.7->5.8 1031 development cycle. Most notably portability across platforms has been 1032 enhanced, and the interval timers (setitimer, getitimer) have been 1033 added. Note that the version of Time::HiRes that is included in Perl 1034 5.8.0 calls itself 1.20_00, but it is equivalent to this Time::HiRes 1035 version. Note also that in 1.30 Wegscheid turns over the maintenance 1036 to Jarkko Hietaniemi. 1037 10381.29_02 [2003-08-16] 1039 1040 - fix a silly unclosed comment typo in HiRes.xs 1041 - document and export REALTIME_REALPROF (Solaris) 1042 10431.29_01 [2003-08-16] 1044 1045 - only getitimer(ITIMER_REAL) available in Cygwin and Win32 1046 (need to patch this also in Perl 5.[89]) 1047 - remove CVS revision log from HiRes.xs 1048 10491.29_00 [2003-08-14] 1050 1051 The following numbered patches refer to the Perl 5.7 changes, 1052 you can browse them at http://public.activestate.com/cgi-bin/perlbrowse 1053 1054 - 17558: Add #!./perl to the .t 1055 - 17201: linux + usemorebits fix, from Rafael Garcia-Suarez 1056 - 16198: political correctness, from Simon Cozens 1057 - 15857: doc tweaks, from Jarkko Hietaniemi 1058 - 15593: optimization in .xs, from Paul Green 1059 - 14892: pod fixes, from Robin Barker 1060 - 14100: VOS fixes, from Paul Green 1061 - 13422: XS segfault, from Marc Lehmann 1062 - 13378: whether select() gets restarted on signals, depends 1063 - 13354: timing constraints, again, from Andy Dougherty 1064 - 13278: can't do subsecond alarms with ualarm; 1065 break out early if alarms do not seem to be working 1066 - 13266: test relaxation (cygwin gets lower hires 1067 times than lores ones) 1068 - 12846: protect against high load, from Jarkko Hietaniemi 1069 - 12837: HiRes.t VMS tweak, from Craig A. Berry 1070 - 12797: HiRes.t VMS tweak, from Charles Lane 1071 - 12769: HiRes.t VMS tweak, from Craig A. Berry 1072 - 12744: gcc vs MS 64-bit constant syntax, from Nick Ing-Simmons 1073 - 12722: VMS ualarm for VMS without ualarm, from Charles Lane 1074 - 12692: alarm() ain't gonna work if ualarm() ain't, 1075 from Gurusamy Sarathy 1076 - 12680: minor VMS tweak, from Charles Lane 1077 - 12617: don't try to print ints as IVs, from Jarkko Hietaniemi 1078 - 12609: croak on negative time, from Jarkko Hietaniemi 1079 - 12595: Cygwin rounds up for time(), from Jarkko Hietaniemi 1080 - 12594: MacOS Classic timeofday, from Chris Nandor 1081 - 12473: allow for more than one second for sleep() and usleep() 1082 - 12458: test tuning, relax timing constraints, 1083 from Jarkko Hietaniemi 1084 - 12449: make sleep() and usleep() to return the number 1085 of seconds and microseconds actually slept (analogously 1086 with the builtin sleep()), also make usleep() croak if 1087 asked for more than 1_000_000 useconds, from Jarkko Hietaniemi 1088 - 12366: Time::HiRes for VMS pre-7.0, from Charles Lane 1089 - 12199: do not use ftime on Win32, from Gurusamy Sarathy 1090 - 12196: use ftime() on Win32, from Artur Bergman 1091 - 12184: fix Time::HiRes gettimeofday() on Win32, from Gurusamy Sarathy 1092 - 12105: use GetSystemTime() on Win32, from Artur Bergman 1093 - 12060: explain the 1e9 seconds problem, from Jarkko Hietaniemi 1094 - 11901: UNICOS sloppy division, from Jarkko Hietaniemi 1095 - 11797: problem in HiRes.t, from John P. Linderman 1096 - 11414: prototype from Time::HiRes::sleep(), from Abhijit Menon-Sen 1097 - 11409: Time::HiRes qw(sleep) failed, from Abhijit Menon-Sen 1098 - 11270: dynix/ptx 4.5.2 hints fix, from Peter Prymmer 1099 - 11032: VAX VMS s/div/lib\$ediv/ fix, from Peter Prymmer 1100 - 11011: VAX VMS s/qdiv/div/ fix, from Peter Prymmer 1101 - 10953: SCO OpenServer 5.0.5 requires an explicit -lc for usleep(), 1102 from Jonathan Stowe 1103 - 10942: MPE/IX test tweaks, from Mark Bixby 1104 - 10784: unnecessary pod2man calls, from Andy Dougherty 1105 - 10354: ext/ + -Wall, from Doug MacEachern 1106 - 10320: fix the BOOT section to call myU2time correctly 1107 - 10317: correct casting for AIX< from H. Merijn Brand 1108 - 10119: document that the core time() may be rounding, not truncating 1109 - 10118: test fix, from John Peacock 1110 - 9988: long =item, from Robin Barker 1111 - 9714: correct test output 1112 - 9708: test also the scalar aspect of getitimer() 1113 - 9705: Add interval timers (setitimer, getitimer) 1114 - 9692: do not require at least 5.005 using XS 1115 1116 The following changes were made on top of the changes 1117 made for Time::HiRes during the Perl 5.7 development 1118 cycle that culminated in the release of Perl 5.8.0. 1119 1120 - add "require 5.005" to the Makefile.PL 1121 - remove the REVISION section (CVS log) from HiRes.pm 1122 - add jhi's copyright alongside Douglas' 1123 - move HiRes.pm to lib/Time/ 1124 - move HiRes.t to t/ 1125 - modify HiRes.t to use $ENV{PERL_CORE} 1126 - modify the original Time::HiRes version 1.20 Makefile.PL 1127 to work both with Perl 5.8.0 and the new code with pre-5.8.0 1128 Perls (tried with 5.6.1) 1129 - tiny tweaks and updates in README and TODO 1130 - bump the VERSION to 1.29 1131 11321.20 Wed Feb 24 21:30 1999 1133 - make our usleep and ualarm substitutes into hrt_usleep 1134 and hrt_ualarm. This helps static links of Perl with other 1135 packages that also have usleep, etc. From 1136 Ilya Zakharevich <ilya@math.ohio-state.edu> 1137 - add C API stuff. From Joshua Pritikin 1138 <joshua.pritikin@db.com> 1139 - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer) 1140 - hopefully correct "-lc" fix for SCO. 1141 - add PPD stuff 1142 1143 1.20 adds a platform neutral set of C accessible routines if you are 1144 running 5.005+. All other changes are packaging changes and build 1145 fixes(?) for statically linked Perl, SCO, and VMS. 1146 11471.19 Tue Sep 29 22:30 1998 1148 - put VMS gettimeofday() in. Patch is from Sebastian Bazley 1149 <seb@stian.demon.co.uk> 1150 - change GIMME_V to GIMME to help people with older versions of 1151 Perl. 1152 - fix Win32 version of gettimeofday(). It didn't affect anything, 1153 but it confuses people reading the code when the return value 1154 is backwards (0 is success). 1155 - fix Makefile.PL (more) so that detection of gettimeofday is 1156 more correct. 1157 1158 1.19 has better VMS support. 1159 11601.18 Mon Jul 6 22:40 1998 1161 - add usleep() for Win32. 1162 - fix Makefile.PL to fix reported HP/UX feature where unresolved 1163 externals still cause an executable to be generated (though no 1164 x bit set). Thanks to David Kozinn for report and explanation. 1165 Problems with the fix are mine :) 1166 1167 1.18 has limited Win32 support (no ualarm). Added usleep for Win32. 1168 Probably buggy. I'm sure I'll hear. 1169 11701.17 Wed Jul 1 20:10 1998 1171 - fix setitimer calls so microseconds is not more than 1000000. 1172 Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD. 1173 - make Win32. We only get gettimeofday (the select hack doesn't 1174 seem to work on my Win95 system). 1175 - fix test 4 on 01test.t. add test to see if time() and 1176 Time::HiRes::time() are close. 1177 11781.16 Wed Nov 12 21:05 1997 1179 - add missing EXTEND in new gettimeofday scalar code. 1180 1181 1.16+ should be closer to building out of the box on Linux. Thanks 1182 to Gisle Aas for patches, and the ualarm equivalent using setitimer. 1183 1184 If your underlying operating system doesn't implement ualarm(), then 1185 a fake using setitimer() will be made. If the OS is missing usleep(), 1186 a fake one using select() will be made. If a fake can't be made for 1187 either ualarm() or usleep(), then the corresponding Perl function will 1188 not be available. If the OS is missing gettimeofday(), you will get 1189 unresolved externals, either at link- or run-time. 1190 1191 This is an improvement; the package used to not even build if 1192 you were missing any of these bits. Roderick Schertler 1193 1194 <roderick@argon.org> did all the conditional compilation stuff, 1195 look at HiRes.pm and the test suites; it's good educational reading. 1196 11971.15 Mon Nov 10 21:30 1997 1198 - HiRes.pm: update pod. Provided by Gisle Aas. 1199 - HiRes.xs: if gettimeofday() called in scalar context, do 1200 something more useful than before. Provided by Gisle Aas. 1201 - README: tell of xsubpp '-nolinenumber' woes. thanks to 1202 Edward Henigin <ed@texas.net> for pointing out the problem. 1203 12041.14 Wed Nov 5 9:40 1997 1205 - Makefile.PL: look for setitimer 1206 - HiRes.xs: if missing ualarm, but we have setitimer, make up 1207 our own setitimer. These were provided by Gisle Aas. 1208 12091.13 Tue Nov 4 23:30 1997 1210 - Makefile.PL: fix autodetect mechanism to do try linking in addition 1211 to just compiling; should fix Linux build problem. Fix was provided 1212 by Gisle Aas. 1213 12141.12 Sun Oct 12 12:00:00 1997 1215 - Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug; 1216 you may need to comment this back out if you have an older xsubpp. 1217 - HiRes.xs: set PROTOTYPES: DISABLE 1218 12191.11 Fri Sep 05 16:00:00 1997 1220 - Makefile.PL: 1221 Had some line commented out that shouldn't have been (testing 1222 remnants) 1223 - README: 1224 Previous version was corrupted. 1225 12261.10 Thu May 22 20:20:00 1997 1227 - HiRes.xs, HiRes.pm, t/*: 1228 - only compile what we have OS support for (or can 1229 fake with select()) 1230 - only test what we compiled 1231 - gross improvement to the test suite 1232 - fix EXPORT_FAIL. 1233 This work was all done by Roderick Schertler 1234 <roderick@argon.org>. If you run Linux or 1235 one of the other ualarm-less platforms, and you like this 1236 module, let Roderick know; without him, it still wouldn't 1237 be working on those boxes... 1238 - Makefile.PL: figure out what routines the OS has and 1239 only build what we need. These bits were written by Jarkko 1240 Hietaniemi <jhi@iki.fi>. Again, gratitude is due... 1241 12421.02 Mon Dec 30 08:00:00 1996 1243 - HiRes.pm: update documentation to say what to do when missing 1244 ualarm() and friends. 1245 - README: update to warn that ualarm() and friends need to exist 1246 12471.01 Fri Oct 17 08:00:00 1996 1248 - Makefile.PL: make XSPROTOARGS => '-noprototyopes' 1249 - HiRes.pm: put blank line between __END__ and =head1 so that 1250 pod2man works. 1251 12521.00 Tue Sep 03 13:00:00 1996 1253 - original version; created by h2xs 1.16 1254
