1 Revision history for Perl extension Time::HiRes.
4 - HiRes.t:s/ok 32/ok 33/, from Dominic Dunlop
5 - tighten up the clock() test marginally by requiring non-negative
6 - clock_nanosleep() and clock() doc tweaks
9 - the interface to clock_nanosleep() is more natural
10 when it is like (hires) time() (instead of like nanosleep),
11 and the .xs implementation of clock_nanosleep() in 1.84
13 - the semantics of clock() are not quite so silly as I thought,
14 but still somewhat odd, documented as such
15 - additional enhancements to the clock() documentation
16 - add test for clock_nanosleep() (I cannot test this
17 since none of my systems have the function)
18 - add test for clock()
21 - add clock() which returns the processor time in
22 (floating point) seconds since an arbitrary era
23 - add clock_nanosleep() which suspends the current
24 thread until either absolute time or for relative time
25 - [rt.cpan.org #16486] printf missing value in HiRes.t
26 - add constants CLOCKS_PER_SEC, CLOCK_SOFTTIME, TIMER_ABSTIME
30 - has_symbol() was wrong since e.g. ITIMER_VIRTUAL is exported
31 via @EXPORT_OK even when it is not available. This is heinous.
32 @EXPORT_OK should be determined at Makefile.PL time.
33 - be more lenient is testing clock_gettime(): allow more slop,
34 and retry up to three times, sleeping a random nap between
36 - human months are one-based (noticed by Anton Berezin)
39 - CLOCK_REALTIME is an enum value (of the clockid_t enum)
40 in HP-UX (and might be so elsewhere, too), debugged by
42 - include const-c.inc as late as possible (from Randy Kobes,
43 [rt.cpan.org #15552] to avoid undefined usleep() on Win32
46 - try to be more robust and consistent in the detection of
47 CLOCK_REALTIME and ITIMER_VIRTUAL in HiRes.t: the proper
52 eval 'import Time::HiRes qw($symbol)';
53 return 0 unless $@ eq '';
54 return exists ${"Time::HiRes::$symbol"};
61 in the test. All these moves are needed because
63 1) one cannot directly do eval 'Time::HiRes::FOO_BAR'
64 because FOO_BAR might have a true value of zero
65 (or in the general case an empty string or even undef)
67 2) In case FOO_BAR is not available in this platform,
68 &FOO_BAR avoids the bareword warning
70 - wait more (1.5 seconds instead of 0.1) for the CLOCK_REALTIME test
71 but expect the 'customary' slop of 0.20 instead of 0.25
72 - fixed inside a comment HAS_POLL -> TIME_HIRES_NANOSLEEP
73 - at the end of HiRest.t tell how close we were to termination
76 - Gisle noticed a mistake (using HAS_NANOSLEEP) in 1.79
79 - try nanosleep for emulating usleep -- may help in some weird
80 embedded realtime places which have nanosleep but neither usleep
81 nor select nor poll (doesn't have to be weird embedded realtime
82 place, though -- in many places usleep is nanosleep anyway)
83 - try poll for emulating usleep -- this may help some obscure/old
84 SVR4 places that have neither usleep nor select
85 - a redundant test guard in HiRes.t
88 - ITIMER_VIRTUAL detection in HiRes.t had problems (that we cannot
89 in the general case fail already at 'use' phase is suboptimal)
90 - fixes to the documentation of clock_gettime() and clock_getres()
93 - add support for the POSIX clock_gettime() and clock_getres(),
94 if available, either as library calls or as syscalls
95 - be more defensive about missing functionality: break out
96 early (during 'use') if no e.g. clock_getres() is available,
97 and protect our back by trapping those cases also in HiRes.xs
98 - the test added in 1.76 could cause an endless loop e.g. in Solaris,
99 due to mixing of sleep() and alarm() (bad programmer, no cookie!)
102 - testing for nanosleep had wrong logic which caused nanosleep
103 to become undefined for e.g. Mac OS X
104 - added a test for a core dump that was introduced by Perl 5.8.0
105 safe signals and was fixed for the time of 5.8.1 (one report of
106 the core dump was [perl #20920]), the test skipped pre-5.8.1.
107 - *cough* s/unanosleep/nanosleep/g; *cough*
110 - installation patch from Gisle Aas: in Perls 5.8.x and later
111 use MakeMaker INSTALLDIRS value of 'perl' instead of 'site'.
114 - [cpan #14608] Solaris 8 perl 5.005_03 File::Spec module does not have method rel2abs
115 (the workaround is not to use rel2abs, should not be necessary)
116 - [cpan #14642] U2time wrongly exported on the C API
117 (patch supplied by the reporter, SALVA@cpan.org)
118 - add release dates to Changes
121 - Time::HiRes::nanosleep support for Solaris [PATCH]
122 (POSIX::uname() not available if building with core perl,
123 from Gisle Aas, via perl5-porters, perl change #25295)
126 - going back to the 1.68 loader setup (using DynaLoader)
127 since too many weird things starting breaking
128 - fix a typo in José Auguste-Etienne's name
131 - a thinko in the nanosleep() detection
132 - move more changes stuff from the README to Changes
133 - add -w to the Makefile.PL
136 - oops in 1.69 about @ISA (not affecting anything but silly)
137 - add copyright 2005 to HiRes.pm
138 - add copyright and license to HiRes.xs
139 - add copyrights 2003, 2004, 2005 to README
142 - actually run a test for nanosleep
143 (if there is no $Config{d_nanosleep}) since e.g. in AIX 4.2
144 it seems that one can link in nanosleep() but then calling
145 it fails instantly and sets errno to ENOSYS (Not implemented).
146 This may be fixable in the AIX case by figuring out the right
147 (realtime POSIX?) libs and whatnot, but in the general case
148 running a real test case is better. (Of course, this change
149 will no doubt run into portability problems because of the
150 execution step...) Note that because of hysterical raisins
151 most Perls do NOT have $Config{d_nanosleep} (scanning for
152 it by Configure would in many platforms require linking in
153 things like -lrt, which would in many platforms be a bad idea
155 (from José Auguste-Etienne)
156 - support XSLoader also since it's much faster
157 (from Alexey Tourbin)
158 - add SEE ALSO (BSD::Resource and Time::TAI64)
161 - somehow 1.67 had a lot of doubled lines (a major cut-and-paste
162 error suspected), but miraculously it still worked since the
163 doubling took place below the __END__ token
164 - undef Pause() before defining it to avoid redefinition warnings
165 during compilation in case perl.h had already defined Pause()
166 (part of perl change #24271)
170 - (internal) don't ignore the return value of gettimeofday()
171 - (external) return undef or an empty if the C gettimeofday() fails
172 (affects Time::HiRes gettimeofday() and the hires time())
176 - fix the 'hierachy' typo in Makefile.PL [rt.cpan.org #8492]
177 - should now build in Solaris [rt.cpan.org #7165] (since 1.64)
178 - should now build in Cygwin [rt.cpan.org #7535] (since 1.64)
179 - close also [rt.cpan.org #5933] "Time::HiRes::time does not
180 pick up time adjustments like ntp" since ever reproducing it
181 (and therefore verifying a possible fix) in the same environment
182 has become rather unlikely
185 - one should not mix u?alarm and sleep (the tests modified
186 by 1.65, #12 and #13, hung in Solaris), now we just busy
187 loop executing an empty block
188 - in the documentation underline the unspecificity of mixing
190 - small spelling fixes
193 - regenerate ppport.h with Devel::PPPort 3.03,
194 now the MY_CXT_CLONE is defined in ppport.h,
195 we no more need to do that.
197 - the test #12 would often hang in sigsuspend() (at least that's
198 where Mac OS X' ktrace shows it hanging). With the sleep()s
199 changed to sleep(1)s, the tests still pass but no hang after
200 a few hundred repeats.
203 - Win32 and any ithread build: ppport.h didn't define
204 MY_CXT_CLONE, which seems to be a Time-HiRes-ism.
207 - Skip testing if under PERL_CORE and Time::HiRes has not
208 been Configured (from Marcus Holland-Moritz, core change
210 - Use ppport.h generated by Devel::PPPort 3.01,
211 allowing cutting away our own portability code.
212 - Don't use $ENV{PERL_CORE} for < 5.6.0.
213 - Don't use "for my $i" for <= 5.003.
214 - Don't use Pause() for <= 5.003.
215 - Can't use newSVpvf for <= 5.003.
216 (most of the changes from Marcus)
219 - Win32: reset reading from the performance counters every
220 five minutes to better track wall clock time (thanks to
221 PC timers being often quite bad), should help long-running
225 - Win32: Patch from Steve Hay
226 [PATCH] Re: [perl #30755] [Win32] Different results from Time::HiRes::gettimeofdayunder the debugger
227 to [perl #30755] reported by Nigel Sandever
229 - Cygwin: Use the Win32 recalibration code also in Cygwin if the
230 <w32api/windows.h> APIs are available. Cygwin testing by
231 Yitzchak Scott-Thoennes.
233 - Solaris: use -lposix4 to get nanosleep for Solaris 2.6,
234 after that keep using -lrt, patch from Alan Burlison,
235 bug reported in [cpan #7165]
238 - Change the Win32 recalibration limit to 0.5 seconds and tweak
239 the documentation to blather less about the gory details of the
240 Win32 implementation and more about the complications in general
241 of meddling with the system clock.
244 - Document the 1.57 change better.
247 - Win32/Cygwin/MinGW: if the performance counter drifts by more
248 than two seconds from the system clock (due to ntp adjustments,
249 for example), recalibrate our internal counter: from Jan Dubois,
250 based on [cpan #5933] by Jerry D. Hedden.
253 - Give a clearer message if the tests timeout (perl change #22253)
254 - Don't use /tmp or its moral equivalents (perl bug #15036,
258 - Windows: mingw32 patch from Mike Pomraning (use Perl's Const64()
259 instead of VC-specific i64 suffix)
262 - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep
265 - Windows: higher resolution time() by using the Windows
266 performance counter API, from Jan Dubois and Anton Shcherbinin.
267 The exact new higher resolution depends on the hardware,
268 but it should be quite a bit better than using the basic
272 - In AIX (v?) with perl 5.6.1 the HiRes.t can hang after
273 the subtest 18. No known analysis nor fix, but added
274 an alarm (that requires fork() and alarm()) to the test.
277 - doc tweaks from mjd (perl change #20456)
278 - NCR MP-RAS hints file added (svr4.pl) (perl change #21249)
281 - add a message (for non-core builds) to Makefile.PL about
282 the LC_ALL=C workaround
283 - &Time::HiRes::d_nanosleep was broken (perl change #20131)
284 - the nanosleep() probe was broken (perl change #20061)
285 - use existence instead of definedness for feature probes
287 - MPE/iX tweak (perl change #20042)
288 - do not use HAS_NANOSLEEP (perl change #19898)
291 - UVuf for non-IVSIZE platforms (from Keiichiro Nagano)
292 - OS/2 can always mix subsecond sleeps with signals
293 (part of perl change #19789)
296 - workaround for buggy gcc 2.95.3 in openbsd/sparc64
300 - do not use -lrt in Linux (from March Lehmann, perl change #19449)
301 - unnecessary (nanosleep is in libc anyway)
302 - harmful (-lrt slows down execution)
303 - incompatible (with many distributions' pthreads)
306 - do not create files in blib directories under core
307 (perl change #19160, from rgs)
308 - detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd)
311 - guarantee that $xdefine in HiRes.t is always defined
312 (perl change #19109, from IlyaZ)
313 - a cleaner way to detect PERL_CORE (perl change #19111,
317 - add hints/irix.pl to turn off overly POSIX flags that
318 cause hide struct timespec to be hidden (and compilation
319 to fail) (bleadperl change #19085)
320 - documentation tweaks
323 - add c:/temp to the list of temp directories to probe
324 so that cygwin (and win*?) builds are happy. This was
325 needed at least in my cygwin 1.3.20/w2k setup.
328 - modernize the constants code (from Nicholas Clark)
331 - At some point the ability to figure our the correct incdir
332 for EXTERN.h (either a core perl build, or an installed perl)
333 had broken (which lead into all test compiles failing with
334 a core perl build, but thanks to the robustness of Makefile.PL
335 nothing of this was visible). The brokenness seemed to be
336 caused by $ENV{PERL_CORE} not being on for core builds?
337 Now stole a trick from the Encode that sets $ENV{PERL_CORE}
338 right, and both styles of build should work again.
341 - Nicholas Clark noticed that the my_catdir() emulation function
342 was broken (which means that we didn't really work for Perls
344 - inspired by fixing the above made the whole Makefile.PL -w
346 - tightened up the Makefile.PL output, less whitespace
349 - fix from Craig Berry for better building in VMS with PERL_CORE
352 - no functional changes
353 - move lib/Time/HiRes.pm as Hires.pm
354 - libraries scanning was slightly broken (always scanned
355 for a library even when $Config{libs} already had it)
358 - Ray Zimmerman ran into a race condition in Mac OS X.
359 A 0.01-second alarm fired before the test expected.
360 The test first slept indefinitely (blocking for signals)
361 and only after that tested for the signal having been sent.
362 Since the signal had already been sent, the test #12 never
363 completed. The solution: test first, then block.
364 - default to being silent on all probing attempts, set the
365 environment variable VERBOSE to a true value to see the
366 details (the probing command and the possible errors)
369 - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski)
370 - INSTALLDIRS => 'perl' missing which means that Time::HiRes
371 cannot be upgraded from CPAN to override the 5.8.0 version
373 - Time::HiRes 1.35 could not be dropped as-is to bleadperl
374 because the include directories did not adjust themselves
375 if $ENV{PERL_CORE} (Hugo van der Sanden)
376 - add documentation about the restart of select() under alarm()
379 - small documentation tweaks
383 - better VMS operation (Craig Berry)
386 - our time machine is accelerating: now works with Perl 5.004_01
387 (tried with 5.003_07 and 5.002 but I get segmentation faults
388 from running the Makefile.PL with those in Tru64 4.0D)
391 - backward compatibility (pre-5.6.0) tweaks:
392 - no XSLoader in 5.00503, use DynaLoader instead
393 - no SvPV_nolen, either
394 - no PerlProc_pause(), either
395 - now tested with 5.00404 and 5.00503
396 - Makefile.PL requires 5.00404 (no more 5.002)
397 - use nanosleep instead of usleep, if it is available (Wilson Snyder)
398 (this means that one can mix subsecond sleeps with alarms)
399 - because of nanosleep we probe for -lrt and -lposix4
400 - the existence of getitimer/nanosleep/setitimer/ualarm/usleep
401 is available by exportable constants Time::HiRes::d_func
402 (since older Perl do not have them in %Config, and even
403 5.8.0 does not probe for nanosleep)
406 - backward compatibility (pre-5.6.1) tweaks:
407 - define NV if no NVTYPE
408 - define IVdf if needed (note: the Devel::PPPort
409 in 5.8.0 does not try hard hard enough since
410 the IVSIZE might not be defined)
411 - define NVgf if needed
412 - grab the typemap from 5.8.0 for the NV stuff
414 1.31 and 1.32 add more backward compatibility (now all the way
415 back to Perl 5.00404), and using nanosleep() (if available) for
420 - release 1.29_02 as 1.30
422 1.30 adds all the changes made during the Perl 5.6->5.7->5.8
423 development cycle. Most notably portability across platforms has been
424 enhanced, and the interval timers (setitimer, getitimer) have been
425 added. Note that the version of Time::HiRes that is included in Perl
426 5.8.0 calls itself 1.20_00, but it is equivalent to this Time::HiRes
427 version. Note also that in 1.30 Wegscheid turns over the maintenance
428 to Jarkko Hietaniemi.
432 - fix a silly unclosed comment typo in HiRes.xs
433 - document and export REALTIME_REALPROF (Solaris)
437 - only getitimer(ITIMER_REAL) available in Cygwin and Win32
438 (need to patch this also in Perl 5.[89])
439 - remove CVS revision log from HiRes.xs

508 The following changes were made on top of the changes
509 made for Time::HiRes during the Perl 5.7 development
510 cycle that culminated in the release of Perl 5.8.0.
512 - add "require 5.005" to the Makefile.PL
513 - remove the REVISION section (CVS log) from HiRes.pm
514 - add jhi's copyright alongside Douglas'
515 - move HiRes.pm to lib/Time/
517 - modify HiRes.t to use $ENV{PERL_CORE}
518 - modify the original Time::HiRes version 1.20 Makefile.PL
519 to work both with Perl 5.8.0 and the new code with pre-5.8.0
520 Perls (tried with 5.6.1)
521 - tiny tweaks and updates in README and TODO
522 - bump the VERSION to 1.29
524 1.20 Wed Feb 24 21:30 1999
525 - make our usleep and ualarm substitutes into hrt_usleep
526 and hrt_ualarm. This helps static links of Perl with other
527 packages that also have usleep, etc. From
528 Ilya Zakharevich <ilya@math.ohio-state.edu>
529 - add C API stuff. From Joshua Pritikin
530 <joshua.pritikin@db.com>
531 - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer)
532 - hopefully correct "-lc" fix for SCO.
535 1.20 adds a platform neutral set of C accessible routines if you are
536 running 5.005+. All other changes are packaging changes and build
537 fixes(?) for statically linked Perl, SCO, and VMS.
539 1.19 Tue Sep 29 22:30 1998
540 - put VMS gettimeofday() in. Patch is from Sebastian Bazley
541 <seb@stian.demon.co.uk>
542 - change GIMME_V to GIMME to help people with older versions of
544 - fix Win32 version of gettimeofday(). It didn't affect anything,
545 but it confuses people reading the code when the return value
546 is backwards (0 is success).
547 - fix Makefile.PL (more) so that detection of gettimeofday is
550 1.19 has better VMS support.
552 1.18 Mon Jul 6 22:40 1998
553 - add usleep() for Win32.
554 - fix Makefile.PL to fix reported HP/UX feature where unresolved
555 externals still cause an executable to be generated (though no
556 x bit set). Thanks to David Kozinn for report and explanation.
557 Problems with the fix are mine :)
559 1.18 has limited Win32 support (no ualarm). Added usleep for Win32.
560 Probably buggy. I'm sure I'll hear.
562 1.17 Wed Jul 1 20:10 1998
563 - fix setitimer calls so microseconds is not more than 1000000.
564 Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD.
565 - make Win32. We only get gettimeofday (the select hack doesn't
566 seem to work on my Win95 system).
567 - fix test 4 on 01test.t. add test to see if time() and
568 Time::HiRes::time() are close.
570 1.16 Wed Nov 12 21:05 1997
571 - add missing EXTEND in new gettimeofday scalar code.
573 1.16+ should be closer to building out of the box on Linux. Thanks
574 to Gisle Aas for patches, and the ualarm equivalent using setitimer.
576 If your underlying operating system doesn't implement ualarm(), then
577 a fake using setitimer() will be made. If the OS is missing usleep(),
578 a fake one using select() will be made. If a fake can't be made for
579 either ualarm() or usleep(), then the corresponding Perl function will
580 not be available. If the OS is missing gettimeofday(), you will get
581 unresolved externals, either at link- or run-time.
583 This is an improvement; the package used to not even build if
584 you were missing any of these bits. Roderick Schertler
586 <roderick@argon.org> did all the conditional compilation stuff,
587 look at HiRes.pm and the test suites; it's good educational reading.
589 1.15 Mon Nov 10 21:30 1997
590 - HiRes.pm: update pod. Provided by Gisle Aas.
591 - HiRes.xs: if gettimeofday() called in scalar context, do
592 something more useful than before. Provided by Gisle Aas.
593 - README: tell of xsubpp '-nolinenumber' woes. thanks to
594 Edward Henigin <ed@texas.net> for pointing out the problem.
596 1.14 Wed Nov 5 9:40 1997
597 - Makefile.PL: look for setitimer
598 - HiRes.xs: if missing ualarm, but we have setitimer, make up
599 our own setitimer. These were provided by Gisle Aas.
601 1.13 Tue Nov 4 23:30 1997
602 - Makefile.PL: fix autodetect mechanism to do try linking in addition
603 to just compiling; should fix Linux build problem. Fix was provided
606 1.12 Sun Oct 12 12:00:00 1997
607 - Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug;
608 you may need to comment this back out if you have an older xsubpp.
609 - HiRes.xs: set PROTOTYPES: DISABLE
611 1.11 Fri Sep 05 16:00:00 1997
613 Had some line commented out that shouldn't have been (testing
616 Previous version was corrupted.
618 1.10 Thu May 22 20:20:00 1997
619 - HiRes.xs, HiRes.pm, t/*:
620 - only compile what we have OS support for (or can
622 - only test what we compiled
623 - gross improvement to the test suite
625 This work was all done by Roderick Schertler
626 <roderick@argon.org>. If you run Linux or
627 one of the other ualarm-less platforms, and you like this
628 module, let Roderick know; without him, it still wouldn't
629 be working on those boxes...
630 - Makefile.PL: figure out what routines the OS has and
631 only build what we need. These bits were written by Jarkko
632 Hietaniemi <jhi@iki.fi>. Again, gratitude is due...
634 1.02 Mon Dec 30 08:00:00 1996
635 - HiRes.pm: update documentation to say what to do when missing
636 ualarm() and friends.
637 - README: update to warn that ualarm() and friends need to exist
639 1.01 Fri Oct 17 08:00:00 1996
640 - Makefile.PL: make XSPROTOARGS => '-noprototyopes'
641 - HiRes.pm: put blank line between __END__ and =head1 so that
644 1.00 Tue Sep 03 13:00:00 1996
