1 Revision history for Perl extension Time::HiRes.
4 - Const64() already appends an 'LL' (or i64), so provide LL and i64
5 forms for the IV_1E[679] (effects Win32 and Cygwin).
6 - the Changes entry for 1.88 talked about [IN]V_1[679], missing the 'E'.
9 - clean up the g++ warnings in HiRes.xs, all of them
10 about mixing integer and floating point, introduce
11 constants IV_1E[679] and NV_1E[679]
14 - [rt.cpan.org #17442] 'make test' frequently fails under
15 Cygwin Perl v5.8.8, reported and patched by J. R. Hedden
16 (two race condition bugs in the END block in the case the
17 main process dies before the timer process, unearthed
18 by a bug in Cygwin ualarm)
21 - HiRes.t:s/ok 32/ok 33/, from Dominic Dunlop
22 - tighten up the clock() test marginally by requiring non-negative
23 - clock_nanosleep() and clock() doc tweaks
26 - the interface to clock_nanosleep() is more natural
27 when it is like (hires) time() (instead of like nanosleep),
28 and the .xs implementation of clock_nanosleep() in 1.84
30 - the semantics of clock() are not quite so silly as I thought,
31 but still somewhat odd, documented as such
32 - additional enhancements to the clock() documentation
33 - add test for clock_nanosleep() (I cannot test this
34 since none of my systems have the function)
35 - add test for clock()
38 - add clock() which returns the processor time in
39 (floating point) seconds since an arbitrary era
40 - add clock_nanosleep() which suspends the current
41 thread until either absolute time or for relative time
42 - [rt.cpan.org #16486] printf missing value in HiRes.t
43 - add constants CLOCKS_PER_SEC, CLOCK_SOFTTIME, TIMER_ABSTIME
47 - has_symbol() was wrong since e.g. ITIMER_VIRTUAL is exported
48 via @EXPORT_OK even when it is not available. This is heinous.
49 @EXPORT_OK should be determined at Makefile.PL time.
50 - be more lenient is testing clock_gettime(): allow more slop,
51 and retry up to three times, sleeping a random nap between
53 - human months are one-based (noticed by Anton Berezin)
56 - CLOCK_REALTIME is an enum value (of the clockid_t enum)
57 in HP-UX (and might be so elsewhere, too), debugged by
59 - include const-c.inc as late as possible (from Randy Kobes,
60 [rt.cpan.org #15552] to avoid undefined usleep() on Win32
63 - try to be more robust and consistent in the detection of
64 CLOCK_REALTIME and ITIMER_VIRTUAL in HiRes.t: the proper
69 eval 'import Time::HiRes qw($symbol)';
70 return 0 unless $@ eq '';
71 return exists ${"Time::HiRes::$symbol"};
78 in the test. All these moves are needed because
80 1) one cannot directly do eval 'Time::HiRes::FOO_BAR'
81 because FOO_BAR might have a true value of zero
82 (or in the general case an empty string or even undef)
84 2) In case FOO_BAR is not available in this platform,
85 &FOO_BAR avoids the bareword warning
87 - wait more (1.5 seconds instead of 0.1) for the CLOCK_REALTIME test
88 but expect the 'customary' slop of 0.20 instead of 0.25
89 - fixed inside a comment HAS_POLL -> TIME_HIRES_NANOSLEEP
90 - at the end of HiRest.t tell how close we were to termination
93 - Gisle noticed a mistake (using HAS_NANOSLEEP) in 1.79
96 - try nanosleep for emulating usleep -- may help in some weird
97 embedded realtime places which have nanosleep but neither usleep
98 nor select nor poll (doesn't have to be weird embedded realtime
99 place, though -- in many places usleep is nanosleep anyway)
100 - try poll for emulating usleep -- this may help some obscure/old
101 SVR4 places that have neither usleep nor select
102 - a redundant test guard in HiRes.t
105 - ITIMER_VIRTUAL detection in HiRes.t had problems (that we cannot
106 in the general case fail already at 'use' phase is suboptimal)
107 - fixes to the documentation of clock_gettime() and clock_getres()
110 - add support for the POSIX clock_gettime() and clock_getres(),
111 if available, either as library calls or as syscalls
112 - be more defensive about missing functionality: break out
113 early (during 'use') if no e.g. clock_getres() is available,
114 and protect our back by trapping those cases also in HiRes.xs
115 - the test added in 1.76 could cause an endless loop e.g. in Solaris,
116 due to mixing of sleep() and alarm() (bad programmer, no cookie!)
119 - testing for nanosleep had wrong logic which caused nanosleep
120 to become undefined for e.g. Mac OS X
121 - added a test for a core dump that was introduced by Perl 5.8.0
122 safe signals and was fixed for the time of 5.8.1 (one report of
123 the core dump was [perl #20920]), the test skipped pre-5.8.1.
124 - *cough* s/unanosleep/nanosleep/g; *cough*
127 - installation patch from Gisle Aas: in Perls 5.8.x and later
128 use MakeMaker INSTALLDIRS value of 'perl' instead of 'site'.
131 - [cpan #14608] Solaris 8 perl 5.005_03 File::Spec module does not have method rel2abs
132 (the workaround is not to use rel2abs, should not be necessary)
133 - [cpan #14642] U2time wrongly exported on the C API
134 (patch supplied by the reporter, SALVA@cpan.org)
135 - add release dates to Changes
138 - Time::HiRes::nanosleep support for Solaris [PATCH]
139 (POSIX::uname() not available if building with core perl,
140 from Gisle Aas, via perl5-porters, perl change #25295)
143 - going back to the 1.68 loader setup (using DynaLoader)
144 since too many weird things starting breaking
145 - fix a typo in José Auguste-Etienne's name
148 - a thinko in the nanosleep() detection
149 - move more changes stuff from the README to Changes
150 - add -w to the Makefile.PL
153 - oops in 1.69 about @ISA (not affecting anything but silly)
154 - add copyright 2005 to HiRes.pm
155 - add copyright and license to HiRes.xs
156 - add copyrights 2003, 2004, 2005 to README
159 - actually run a test for nanosleep
160 (if there is no $Config{d_nanosleep}) since e.g. in AIX 4.2
161 it seems that one can link in nanosleep() but then calling
162 it fails instantly and sets errno to ENOSYS (Not implemented).
163 This may be fixable in the AIX case by figuring out the right
164 (realtime POSIX?) libs and whatnot, but in the general case
165 running a real test case is better. (Of course, this change
166 will no doubt run into portability problems because of the
167 execution step...) Note that because of hysterical raisins
168 most Perls do NOT have $Config{d_nanosleep} (scanning for
169 it by Configure would in many platforms require linking in
170 things like -lrt, which would in many platforms be a bad idea
172 (from José Auguste-Etienne)
173 - support XSLoader also since it's much faster
174 (from Alexey Tourbin)
175 - add SEE ALSO (BSD::Resource and Time::TAI64)
178 - somehow 1.67 had a lot of doubled lines (a major cut-and-paste
179 error suspected), but miraculously it still worked since the
180 doubling took place below the __END__ token
181 - undef Pause() before defining it to avoid redefinition warnings
182 during compilation in case perl.h had already defined Pause()
183 (part of perl change #24271)
187 - (internal) don't ignore the return value of gettimeofday()
188 - (external) return undef or an empty if the C gettimeofday() fails
189 (affects Time::HiRes gettimeofday() and the hires time())
193 - fix the 'hierachy' typo in Makefile.PL [rt.cpan.org #8492]
194 - should now build in Solaris [rt.cpan.org #7165] (since 1.64)
195 - should now build in Cygwin [rt.cpan.org #7535] (since 1.64)
196 - close also [rt.cpan.org #5933] "Time::HiRes::time does not
197 pick up time adjustments like ntp" since ever reproducing it
198 (and therefore verifying a possible fix) in the same environment
199 has become rather unlikely
202 - one should not mix u?alarm and sleep (the tests modified
203 by 1.65, #12 and #13, hung in Solaris), now we just busy
204 loop executing an empty block
205 - in the documentation underline the unspecificity of mixing
207 - small spelling fixes
210 - regenerate ppport.h with Devel::PPPort 3.03,
211 now the MY_CXT_CLONE is defined in ppport.h,
212 we no more need to do that.
214 - the test #12 would often hang in sigsuspend() (at least that's
215 where Mac OS X' ktrace shows it hanging). With the sleep()s
216 changed to sleep(1)s, the tests still pass but no hang after
217 a few hundred repeats.
220 - Win32 and any ithread build: ppport.h didn't define
221 MY_CXT_CLONE, which seems to be a Time-HiRes-ism.
224 - Skip testing if under PERL_CORE and Time::HiRes has not
225 been Configured (from Marcus Holland-Moritz, core change
227 - Use ppport.h generated by Devel::PPPort 3.01,
228 allowing cutting away our own portability code.
229 - Don't use $ENV{PERL_CORE} for < 5.6.0.
230 - Don't use "for my $i" for <= 5.003.
231 - Don't use Pause() for <= 5.003.
232 - Can't use newSVpvf for <= 5.003.
233 (most of the changes from Marcus)
236 - Win32: reset reading from the performance counters every
237 five minutes to better track wall clock time (thanks to
238 PC timers being often quite bad), should help long-running
242 - Win32: Patch from Steve Hay
243 [PATCH] Re: [perl #30755] [Win32] Different results from Time::HiRes::gettimeofdayunder the debugger
244 to [perl #30755] reported by Nigel Sandever
246 - Cygwin: Use the Win32 recalibration code also in Cygwin if the
247 <w32api/windows.h> APIs are available. Cygwin testing by
248 Yitzchak Scott-Thoennes.
250 - Solaris: use -lposix4 to get nanosleep for Solaris 2.6,
251 after that keep using -lrt, patch from Alan Burlison,
252 bug reported in [cpan #7165]
255 - Change the Win32 recalibration limit to 0.5 seconds and tweak
256 the documentation to blather less about the gory details of the
257 Win32 implementation and more about the complications in general
258 of meddling with the system clock.
261 - Document the 1.57 change better.
264 - Win32/Cygwin/MinGW: if the performance counter drifts by more
265 than two seconds from the system clock (due to ntp adjustments,
266 for example), recalibrate our internal counter: from Jan Dubois,
267 based on [cpan #5933] by Jerry D. Hedden.
270 - Give a clearer message if the tests timeout (perl change #22253)
271 - Don't use /tmp or its moral equivalents (perl bug #15036,
275 - Windows: mingw32 patch from Mike Pomraning (use Perl's Const64()
276 instead of VC-specific i64 suffix)
279 - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep
282 - Windows: higher resolution time() by using the Windows
283 performance counter API, from Jan Dubois and Anton Shcherbinin.
284 The exact new higher resolution depends on the hardware,
285 but it should be quite a bit better than using the basic
289 - In AIX (v?) with perl 5.6.1 the HiRes.t can hang after
290 the subtest 18. No known analysis nor fix, but added
291 an alarm (that requires fork() and alarm()) to the test.
294 - doc tweaks from mjd (perl change #20456)
295 - NCR MP-RAS hints file added (svr4.pl) (perl change #21249)
298 - add a message (for non-core builds) to Makefile.PL about
299 the LC_ALL=C workaround
300 - &Time::HiRes::d_nanosleep was broken (perl change #20131)
301 - the nanosleep() probe was broken (perl change #20061)
302 - use existence instead of definedness for feature probes
304 - MPE/iX tweak (perl change #20042)
305 - do not use HAS_NANOSLEEP (perl change #19898)
308 - UVuf for non-IVSIZE platforms (from Keiichiro Nagano)
309 - OS/2 can always mix subsecond sleeps with signals
310 (part of perl change #19789)
313 - workaround for buggy gcc 2.95.3 in openbsd/sparc64
317 - do not use -lrt in Linux (from March Lehmann, perl change #19449)
318 - unnecessary (nanosleep is in libc anyway)
319 - harmful (-lrt slows down execution)
320 - incompatible (with many distributions' pthreads)
323 - do not create files in blib directories under core
324 (perl change #19160, from rgs)
325 - detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd)
328 - guarantee that $xdefine in HiRes.t is always defined
329 (perl change #19109, from IlyaZ)
330 - a cleaner way to detect PERL_CORE (perl change #19111,
334 - add hints/irix.pl to turn off overly POSIX flags that
335 cause hide struct timespec to be hidden (and compilation
336 to fail) (bleadperl change #19085)
337 - documentation tweaks
340 - add c:/temp to the list of temp directories to probe
341 so that cygwin (and win*?) builds are happy. This was
342 needed at least in my cygwin 1.3.20/w2k setup.
345 - modernize the constants code (from Nicholas Clark)
348 - At some point the ability to figure our the correct incdir
349 for EXTERN.h (either a core perl build, or an installed perl)
350 had broken (which lead into all test compiles failing with
351 a core perl build, but thanks to the robustness of Makefile.PL
352 nothing of this was visible). The brokenness seemed to be
353 caused by $ENV{PERL_CORE} not being on for core builds?
354 Now stole a trick from the Encode that sets $ENV{PERL_CORE}
355 right, and both styles of build should work again.
358 - Nicholas Clark noticed that the my_catdir() emulation function
359 was broken (which means that we didn't really work for Perls
361 - inspired by fixing the above made the whole Makefile.PL -w
363 - tightened up the Makefile.PL output, less whitespace
366 - fix from Craig Berry for better building in VMS with PERL_CORE
369 - no functional changes
370 - move lib/Time/HiRes.pm as Hires.pm
371 - libraries scanning was slightly broken (always scanned
372 for a library even when $Config{libs} already had it)
375 - Ray Zimmerman ran into a race condition in Mac OS X.
376 A 0.01-second alarm fired before the test expected.
377 The test first slept indefinitely (blocking for signals)
378 and only after that tested for the signal having been sent.
379 Since the signal had already been sent, the test #12 never
380 completed. The solution: test first, then block.
381 - default to being silent on all probing attempts, set the
382 environment variable VERBOSE to a true value to see the
383 details (the probing command and the possible errors)
386 - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski)
387 - INSTALLDIRS => 'perl' missing which means that Time::HiRes
388 cannot be upgraded from CPAN to override the 5.8.0 version
390 - Time::HiRes 1.35 could not be dropped as-is to bleadperl
391 because the include directories did not adjust themselves
392 if $ENV{PERL_CORE} (Hugo van der Sanden)
393 - add documentation about the restart of select() under alarm()
396 - small documentation tweaks
400 - better VMS operation (Craig Berry)
403 - our time machine is accelerating: now works with Perl 5.004_01
404 (tried with 5.003_07 and 5.002 but I get segmentation faults
405 from running the Makefile.PL with those in Tru64 4.0D)
408 - backward compatibility (pre-5.6.0) tweaks:
409 - no XSLoader in 5.00503, use DynaLoader instead
410 - no SvPV_nolen, either
411 - no PerlProc_pause(), either
412 - now tested with 5.00404 and 5.00503
413 - Makefile.PL requires 5.00404 (no more 5.002)
414 - use nanosleep instead of usleep, if it is available (Wilson Snyder)
415 (this means that one can mix subsecond sleeps with alarms)
416 - because of nanosleep we probe for -lrt and -lposix4
417 - the existence of getitimer/nanosleep/setitimer/ualarm/usleep
418 is available by exportable constants Time::HiRes::d_func
419 (since older Perl do not have them in %Config, and even
420 5.8.0 does not probe for nanosleep)
423 - backward compatibility (pre-5.6.1) tweaks:
424 - define NV if no NVTYPE
425 - define IVdf if needed (note: the Devel::PPPort
426 in 5.8.0 does not try hard hard enough since
427 the IVSIZE might not be defined)
428 - define NVgf if needed
429 - grab the typemap from 5.8.0 for the NV stuff
431 1.31 and 1.32 add more backward compatibility (now all the way
432 back to Perl 5.00404), and using nanosleep() (if available) for
437 - release 1.29_02 as 1.30
439 1.30 adds all the changes made during the Perl 5.6->5.7->5.8
440 development cycle. Most notably portability across platforms has been
441 enhanced, and the interval timers (setitimer, getitimer) have been
442 added. Note that the version of Time::HiRes that is included in Perl
443 5.8.0 calls itself 1.20_00, but it is equivalent to this Time::HiRes
444 version. Note also that in 1.30 Wegscheid turns over the maintenance
445 to Jarkko Hietaniemi.
449 - fix a silly unclosed comment typo in HiRes.xs
450 - document and export REALTIME_REALPROF (Solaris)
454 - only getitimer(ITIMER_REAL) available in Cygwin and Win32
455 (need to patch this also in Perl 5.[89])
456 - remove CVS revision log from HiRes.xs

525 The following changes were made on top of the changes
526 made for Time::HiRes during the Perl 5.7 development
527 cycle that culminated in the release of Perl 5.8.0.
529 - add "require 5.005" to the Makefile.PL
530 - remove the REVISION section (CVS log) from HiRes.pm
531 - add jhi's copyright alongside Douglas'
532 - move HiRes.pm to lib/Time/
534 - modify HiRes.t to use $ENV{PERL_CORE}
535 - modify the original Time::HiRes version 1.20 Makefile.PL
536 to work both with Perl 5.8.0 and the new code with pre-5.8.0
537 Perls (tried with 5.6.1)
538 - tiny tweaks and updates in README and TODO
539 - bump the VERSION to 1.29
541 1.20 Wed Feb 24 21:30 1999
542 - make our usleep and ualarm substitutes into hrt_usleep
543 and hrt_ualarm. This helps static links of Perl with other
544 packages that also have usleep, etc. From
545 Ilya Zakharevich <ilya@math.ohio-state.edu>
546 - add C API stuff. From Joshua Pritikin
547 <joshua.pritikin@db.com>
548 - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer)
549 - hopefully correct "-lc" fix for SCO.
552 1.20 adds a platform neutral set of C accessible routines if you are
553 running 5.005+. All other changes are packaging changes and build
554 fixes(?) for statically linked Perl, SCO, and VMS.
556 1.19 Tue Sep 29 22:30 1998
557 - put VMS gettimeofday() in. Patch is from Sebastian Bazley
558 <seb@stian.demon.co.uk>
559 - change GIMME_V to GIMME to help people with older versions of
561 - fix Win32 version of gettimeofday(). It didn't affect anything,
562 but it confuses people reading the code when the return value
563 is backwards (0 is success).
564 - fix Makefile.PL (more) so that detection of gettimeofday is
567 1.19 has better VMS support.
569 1.18 Mon Jul 6 22:40 1998
570 - add usleep() for Win32.
571 - fix Makefile.PL to fix reported HP/UX feature where unresolved
572 externals still cause an executable to be generated (though no
573 x bit set). Thanks to David Kozinn for report and explanation.
574 Problems with the fix are mine :)
576 1.18 has limited Win32 support (no ualarm). Added usleep for Win32.
577 Probably buggy. I'm sure I'll hear.
579 1.17 Wed Jul 1 20:10 1998
580 - fix setitimer calls so microseconds is not more than 1000000.
581 Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD.
582 - make Win32. We only get gettimeofday (the select hack doesn't
583 seem to work on my Win95 system).
584 - fix test 4 on 01test.t. add test to see if time() and
585 Time::HiRes::time() are close.
587 1.16 Wed Nov 12 21:05 1997
588 - add missing EXTEND in new gettimeofday scalar code.
590 1.16+ should be closer to building out of the box on Linux. Thanks
591 to Gisle Aas for patches, and the ualarm equivalent using setitimer.
593 If your underlying operating system doesn't implement ualarm(), then
594 a fake using setitimer() will be made. If the OS is missing usleep(),
595 a fake one using select() will be made. If a fake can't be made for
596 either ualarm() or usleep(), then the corresponding Perl function will
597 not be available. If the OS is missing gettimeofday(), you will get
598 unresolved externals, either at link- or run-time.
600 This is an improvement; the package used to not even build if
601 you were missing any of these bits. Roderick Schertler
603 <roderick@argon.org> did all the conditional compilation stuff,
604 look at HiRes.pm and the test suites; it's good educational reading.
606 1.15 Mon Nov 10 21:30 1997
607 - HiRes.pm: update pod. Provided by Gisle Aas.
608 - HiRes.xs: if gettimeofday() called in scalar context, do
609 something more useful than before. Provided by Gisle Aas.
610 - README: tell of xsubpp '-nolinenumber' woes. thanks to
611 Edward Henigin <ed@texas.net> for pointing out the problem.
613 1.14 Wed Nov 5 9:40 1997
614 - Makefile.PL: look for setitimer
615 - HiRes.xs: if missing ualarm, but we have setitimer, make up
616 our own setitimer. These were provided by Gisle Aas.
618 1.13 Tue Nov 4 23:30 1997
619 - Makefile.PL: fix autodetect mechanism to do try linking in addition
620 to just compiling; should fix Linux build problem. Fix was provided
623 1.12 Sun Oct 12 12:00:00 1997
624 - Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug;
625 you may need to comment this back out if you have an older xsubpp.
626 - HiRes.xs: set PROTOTYPES: DISABLE
628 1.11 Fri Sep 05 16:00:00 1997
630 Had some line commented out that shouldn't have been (testing
633 Previous version was corrupted.
635 1.10 Thu May 22 20:20:00 1997
636 - HiRes.xs, HiRes.pm, t/*:
637 - only compile what we have OS support for (or can
639 - only test what we compiled
640 - gross improvement to the test suite
642 This work was all done by Roderick Schertler
643 <roderick@argon.org>. If you run Linux or
644 one of the other ualarm-less platforms, and you like this
645 module, let Roderick know; without him, it still wouldn't
646 be working on those boxes...
647 - Makefile.PL: figure out what routines the OS has and
648 only build what we need. These bits were written by Jarkko
649 Hietaniemi <jhi@iki.fi>. Again, gratitude is due...
651 1.02 Mon Dec 30 08:00:00 1996
652 - HiRes.pm: update documentation to say what to do when missing
653 ualarm() and friends.
654 - README: update to warn that ualarm() and friends need to exist
656 1.01 Fri Oct 17 08:00:00 1996
657 - Makefile.PL: make XSPROTOARGS => '-noprototyopes'
658 - HiRes.pm: put blank line between __END__ and =head1 so that
661 1.00 Tue Sep 03 13:00:00 1996
662 - original version; created by h2xs 1.16
