Ports
+ * Our default I/O size (8 MiB) for large files was too large for some
+ platforms with smaller SSIZE_MAX, leading to read(2)/write(2)
+ failures.
+
+ * We did not check the curl library version before using
+ CURLOPT_PROXYAUTH feature that may not exist.
+
UI, Workflows & Features
* Using environment variable LANGUAGE and friends on the client side,
HTTP-based transports now send Accept-Language when making requests.
+ * "git send-email" used to accept a mistaken "y" (or "yes") as an
+ answer to "What encoding do you want to use [UTF-8]? " without
+ questioning. Now it asks for confirmation when the answer looks
+ too short to be a valid encoding name.
+
+ * When "git apply --whitespace=fix" fixed whitespace errors in the
+ common context lines, the command reports that it did so.
+
Performance, Internal Implementation, Development Support etc.
* Implementation of "reflog expire" has been restructured to fit the
reflogs better with the recently updated ref API.
+ * The transport-helper did not give transport options such as
+ verbosity, progress, cloning, etc. to import and export based
+ helpers, like it did for fetch and push based helpers, robbing them
+ the chance to honor the wish of the end-users better.
+
+ * The tests that wanted to see that file becomes unreadable after
+ running "chmod a-r file", and the tests that wanted to make sure it
+ is not run as root, we used "can we write into the / directory?" as
+ a cheap substitute, but on some platforms that is not a good
+ heuristics. The tests and their prerequisites have been updated to
+ check what they really require.
+ (merge f400e51 jk/sanity later to maint).
+
+ * Various issues around "reflog expire", e.g. using --updateref when
+ expiring a reflog for a symbolic reference, have been corrected
+ and/or made saner.
+
+ * The strbuf API was explained between the API documentation and in
+ the header file. Move missing bits to strbuf.h so that programmers
+ can check only one place for all necessary information.
+
+ * The error handling functions and conventions are now documented in
+ the API manual.
+
+ * Optimize attribute look-up, mostly useful in "git grep" on a
+ project that does not use many attributes, by avoiding it when we
+ (should) know that the attributes are not defined in the first
+ place.
+
+ * Typofix in comments.
+ (merge ef2956a ak/git-pm-typofix later to maint).
+
+ * Code clean-up.
+ (merge 0b868f0 sb/hex-object-name-is-at-most-41-bytes-long later to maint).
+ (merge 5d30851 dp/remove-duplicated-header-inclusion later to maint).
+
+ * Simplify the ref transaction API around how "the ref should be
+ pointing at this object" is specified.
+
Also contains various documentation updates and code clean-ups.
* "git blame" died, trying to free an uninitialized piece of memory.
(merge e600592 es/blame-commit-info-fix later to maint).
+
+ * "git fast-import" used to crash when it could not close and
+ conclude the resulting packfile cleanly.
+ (merge 5e915f3 jk/fast-import-die-nicely-fix later to maint).
+
+ * "update-index --refresh" used to leak when an entry cannot be
+ refreshed for whatever reason.
+ (merge bc1c2ca sb/plug-leak-in-make-cache-entry later to maint).
+
+ * The "interpolated-path" option of "git daemon" inserted any string
+ client declared on the "host=" capability request without checking.
+ Sanitize and limit %H and %CH to a saner and a valid DNS name.
+ (merge b485373 jk/daemon-interpolate later to maint).
+
+ * "git daemon" looked up the hostname even when "%CH" and "%IP"
+ interpolations are not requested, which was unnecessary.
+ (merge dc8edc8 rs/daemon-interpolate later to maint).
+
+ * Even though we officially haven't dropped Perl 5.8 support, the
+ Getopt::Long package that came with it does not support "--no-"
+ prefix to negate a boolean option; manually add support to help
+ people with older Getopt::Long package.
+ (merge f471494 km/send-email-getopt-long-workarounds later to maint).
+
+ * "git apply" was not very careful about reading from, removing,
+ updating and creating paths outside the working tree (under
+ --index/--cached) or the current directory (when used as a
+ replacement for GNU patch).
+ (merge e0d201b jc/apply-beyond-symlink later to maint).
+
+ * A breakage to git-svn around v2.2 era that triggers premature
+ closing of FileHandle has been corrected.
+ (merge e426311 ew/svn-maint-fixes later to maint).
+
+ * We did not parse username followed by literal IPv6 address in SSH
+ transport URLs, e.g. ssh://user@[2001:db8::1]:22/repo.git
+ correctly.
+ (merge 3f55cca tb/connect-ipv6-parse-fix later to maint).
+
+ * The configuration variable 'mailinfo.scissors' was hard to
+ discover in the documentation.
+ (merge afb5de7 mm/am-c-doc later to maint).
+
+ * The interaction between "git submodule update" and the
+ submodule.*.update configuration was not clearly documented.
+ (merge 5c31acf ms/submodule-update-config-doc later to maint).
+
+ * "git diff --shortstat --dirstat=changes" showed a dirstat based on
+ lines that was never asked by the end user in addition to the
+ dirstat that the user asked for.
+ (merge ab27389 mk/diff-shortstat-dirstat-fix later to maint).
+
+ * "git remote add" mentioned "--tags" and "--no-tags" and was not
+ clear that fetch from the remote in the future will use the default
+ behaviour when neither is given to override it.
+ (merge aaba0ab mg/doc-remote-tags-or-not later to maint).
+
+ * Description given by "grep -h" for its --exclude-standard option
+ was phrased poorly.
+ (merge 77fdb8a nd/grep-exclude-standard-help-fix later to maint).
+
+ * The borrowed code in kwset API did not follow our usual convention
+ to use "unsigned char" to store values that range from 0-255.
+ (merge 189c860 bw/kwset-use-unsigned later to maint).
+
+ * A corrupt input to "git diff -M" used to cause it to segfault.
+ (merge 4d6be03 jk/diffcore-rename-duplicate later to maint).
+
+ * Code cleanups and documentaiton updates.
+ (merge 2ce63e9 rs/simple-cleanups later to maint).
