pike.git/CHANGES:1: - Changes since Pike 7.8.116: + Changes since Pike 7.8.116 (initial 7.8 release):   ----------------------------------------------------------------------    -  + FIXME: Mention OOB changes?    -  + FIXME: Mention Stdio.Fd_ref elimination work and related fd work which + includes new functions? +  + FIXME: Mentions thread yield changes? +  + FIXME: Mention "Fixed bug with a C stack check in F_CATCH that could be thrown from a spot where the catch context wasn't properly set up." +  + FIXME: Mention "Stop calling _sprintf or master()->describe_object in + describe_svalue when we're running low on stack, to avoid throwing + out-of-stack errors better while an out-of-stack backtrace is being + formatted."? +  +  + Bugfixes + -------- +  + o Fixed bug in AGGR_ARR_EPILOGUE() (aka END_AGGREGATE_ARRAY()) that +  caused the empty array to always be returned if there were no +  unaggragated elements on the stack at END_AGGREGATE_ARRAY. +  +  You are encouraged to upgrade just for this fix since it creates +  very rare but (seemingly) random occurances of empty arrays. +  + o Fixed multiset_delete_node to work with destructed indices. This +  fixes occasional bugs in various functions when there are destructed +  objects in indices. +  +  You are encouraged to upgrade just for this fix since it creates +  (seemingly) random crashes that are hard to reproduce and track down. +  + o Clean up and fix UTF8/Unicode/wide string support for pgsql. +  +  FIXME: pgsql has changed a bit, anything notable? +  + o Fixed bug when seeking backwards in Gz.File. +  + o Fixed bug in fd_stat on windows when used on a file system with a +  long name. +  + o Fixed off-by-one bug in Stdio.Readline that caused a space in the +  last column to disappear instead of being converted to a linefeed +  when word wrapping is used. +  + o Fix bug in Fakefile.read() +  FIXME: You don't say.... I wonder if I should hack up CVS to refuse +  checkins with a message on the form "Fix[^ ]* bug in [^ ]*". +  + o Image.TIFF: Fixed memory leak on OOM. +  + o Fixed crash bug in Fixed core-dump typo in yyexplain_not_implements(). +  + o LysKOM.ProtocolTypes: Bugfix of LocalToGlobalBlock +  FIXME: Elaborate. +  + o Don't risk hanging on mutexes when threads are disabled in Pike_fatal. +  FIXME: Rephrase +  + o Added 7.6 compat versions for RegGet{Value{,s},KeyNames}(). +  + o Fixed memory leak in Image.Colortable. +  + o Reinstated the class as Parser.SGML(). It inadvertedly became +  Parser.SGML()->SGML() in the move to a separate file. +  Parser.SGML.SGML is kept as a compatibility alias. +  + o Added Pike 7.6 and earlier compat for store_constant(UNDEFINED). +  + o Potential fix for "Lost track of child" on pikes compiled --without-threads. +  + o Regexp.PCRE: Do not match the empty string past the end of the input. +  +  + Optimizations + ------------- +  + o Fixed Filesystem._Tar.ReadFile to not gobble the whole tar entries +  into memory at once. +  + o Improve performance of get_cpu_time() on OS X by avoiding a kernel +  trap to get the ID of the underlying system thread. +  + o Throttle calls to task_info() on OS X since they are quite +  expensive. This gives a significant performance boost (>10%) on +  CPU-intensive applications. +  +  + Extensions and New Functions + ---------------------------- +  + o Added support for specifying (some) modifiers via a mapping in sprintf(). +  +  FIXME: Elaborate. +  +  This support is detectable by checking for +  String.__HAVE_SPRINTF_STAR_MAPPING__ +  + o Added support for generating little-endian floats with %F in sprintf(). +  +  This support is detectable by checking for +  String.__HAVE_SPRINTF_NEGATIVE_F__ +  + o Sql.Sql now supports NULL values for %s-parameters. +  + o Timeout support in win32 threads. +  + o Made FakeFile() support getchar/gets/unread. +  + o Added symlink support to chown and utime. +  FIXME: Review. Symlink support in chown is extremly dangerous if +  done wrong. +  + o function_name() now knows how to adjust the names of named lambdas. +  + o Changed handling of POLLHUP for poll devices, it is now signalled on +  all of the callbacks. +  + o Updated timezone data to tzdata2009c. +  +    New modules / classes / methods added   -------------------------------------      o Protocols.IPv6       Support for the IPv6 protocol. This currently only contains tools to    parse and normalize addresses. (Not much more is necessary since the    usual I/O interfaces support IPv6 as-is.)    -  +  FIXME: Should probably be in Tools or Standards.    -  + o Added Filesystem._Tar.extract to be able to extract many/all files +  in a reasonably efficient way. +  + o Added Parser.Tabular +  FIXME: Description +  + o Calendar.TMD.http_time() that knows how to handle dates according to +  HTTP 1.1 (RFC 2616). +  +  + Building and installing + ----------------------- +  + o Use the #-character as prefix and suffix for placeholders in +  master.pike.in instead of the currency sign, to avoid 8-bit character +  encoding issues. +  + o Disabled "Option Compare Binary" in win32 installer, since it +  apparently isn't supported in vbs. +  + o Improved subbort for bumping via both Subversion and git. +  + o A recent stable Pike (7.8.116+) is now required to do a "make +  export". +  + o The win32 installer now removes the generated master.pike on uninstall. +  +    Changes since Pike 7.6:   ----------------------------------------------------------------------      This is a high level list of changes between Pike 7.6 and Pike 7.8.   General bug fixes, build fixes and optimizations are not mentioned   here.
