Revision history for Perl extension Time::HiRes.
+1.54
+ - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep
+
+1.53
+ - 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
+ - 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
+ - doc tweaks from mjd (perl change #20456)
+ - NCR MP-RAS hints file added (svr4.pl) (perl change #21249)
+
+1.50
+ - 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
+ - UVuf for non-IVSIZE platforms (from Keiichiro Nagano)
+ - OS/2 can always mix subsecond sleeps with signals
+ (part of perl change #19789)
+
+1.48
+ - workaround for buggy gcc 2.95.3 in openbsd/sparc64
+ (perl change #19592)
+
+1.47
+ - 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
+ - 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
+ - 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
+ - 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
+ - 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
+ - modernize the constants code (from Nicholas Clark)
+
+1.41
+ - 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
+ - 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
+ - fix from Craig Berry for better building in VMS with PERL_CORE
+
+1.38
+ - 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
+ - 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
+ - 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
+ - small documentation tweaks
+
+
+1.34
+ - better VMS operation (Craig Berry)
+
+1.33
+ - 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
+ - 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
+ - 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
+1.30
+
+ - release 1.29_02 as 1.30
+
+1.29_02
+
+ - fix a silly unclosed comment typo in HiRes.xs
+ - document and export REALTIME_REALPROF (Solaris)
+
+1.29_01
+
+ - 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

1.20 Wed Feb 24 21:30 1999
