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.
+
+
