Revision history for Perl extension Time::HiRes.
+1.82 [2005-10-06]
+ - CLOCK_REALTIME is an enum value (of the clockid_t enum)
+ in HP-UX (and might be so elsewhere, too), debugged by
+ H. Merijn Brand
+ - include const-c.inc as late as possible (from Randy Kobes,
+ [rt.cpan.org #15552] to avoid undefined usleep() on Win32
+
+1.81 [2005-10-05]
+ - try to be more robust and consistent in the detection of
+ CLOCK_REALTIME and ITIMER_VIRTUAL in HiRes.t: the proper
+ way is
+
+ sub has_symbol {
+ my $symbol = shift;
+ eval 'import Time::HiRes qw($symbol)';
+ return 0 unless $@ eq '';
+ return exists ${"Time::HiRes::$symbol"};
+ }
+
+ and then use
+
+ &FOO_BAR
+
+ in the test. 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 [2005-10-04]
+ - Gisle noticed a mistake (using HAS_NANOSLEEP) in 1.79
+
+1.79 [2005-10-03]
+ - 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 [2005-10-03]
+ - 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 [2005-10-03]
+ - 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-HiResism.
+
+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. Cygwin testing by
+ Yitzchak Scott-Thoennes.
+
+ - Solaris: use -lposix4 to get nanosleep for Solaris 2.6,
+ after that keep using -lrt, patch from Alan Burlison,
+ bug reported in [cpan #7165]
+
+1.59 [2004-04-08]
+ - Change the Win32 recalibration limit to 0.5 seconds and tweak
+ the documentation to blather less about the gory details of the
+ Win32 implementation and more about the complications in general
+ of meddling with the system clock.
+
+1.58 [2004-04-08]
+ - Document the 1.57 change better.
+
+1.57 [2004-07-04]
+ - Win32/Cygwin/MinGW: if the performance counter drifts by more
+ than two seconds from the system clock (due to ntp adjustments,
+ for example), recalibrate our internal counter: from Jan Dubois,
+ based on [cpan #5933] by Jerry D. 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]

+
+ - add "require 5.005" to the Makefile.PL
+ - remove the REVISION section (CVS log) from HiRes.pm
+ - add jhi's copyright alongside Douglas'
+ - move HiRes.pm to lib/Time/
+ - move HiRes.t to t/
+ - modify HiRes.t to use $ENV{PERL_CORE}
+ - modify the original Time::HiRes version 1.20 Makefile.PL
+ to work both with Perl 5.8.0 and the new code with pre-5.8.0
+ Perls (tried with 5.6.1)
+ - tiny tweaks and updates in README and TODO
+ - bump the VERSION to 1.29
+
1.20 Wed Feb 24 21:30 1999
- make our usleep and ualarm substitutes into hrt_usleep
and hrt_ualarm. This helps static links of Perl with other
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)
+ - 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>
- 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
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
+ - make Win32. We only get gettimeofday (the select hack doesn't
seem to work on my Win95 system).

- 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.
