Backward Compatibility Notes
----------------------------
each other.
(merge e5bbe09e88 nd/wildmatch-double-asterisk later to maint).
+ * The "--no-patch" option, which can be used to get a high-level
+ overview without the actual line-by-line patch difference shown, of
+ the "range-diff" command was earlier broken, which has been
+ corrected.
+
+ * The recently merged "rebase in C" has an escape hatch to use the
+ scripted version when necessary, but it hasn't been documented,
+ which has been corrected.
+
Performance, Internal Implementation, Development Support etc.
used during tests are getting renamed for consistency.
(merge 4231d1ba99 bp/rename-test-env-var later to maint).
- * A new extension to the index file has been introduced, which allows
- the index file to be read in parallel for performance.
+ * A pair of new extensions to the index file have been introduced.
+ They allow the index file to be read in parallel for performance.
* The oidset API was built on top of the oidmap API which in turn is
on the hashmap API. Replace the implementation to build on top of
* The support for format-patch (and send-email) by the command-line
completion script (in contrib/) has been simplified a bit.
+ * The revision walker machinery learned to take advantage of the
+ commit generation numbers stored in the commit-graph file.
+
+ * The codebase has been cleaned up to reduce "#ifndef NO_PTHREADS".
+
+ * The way -lcurl library gets linked has been simplified by taking
+ advantage of the fact that we can just ask curl-config command how.
+
+ * Various functions have been audited for "-Wunused-parameter" warnings
+ and bugs in them got fixed.
+
+ * A sanity check for start-up sequence has been added in the config
+ API codepath.
+
+ * The build procedure to link for fuzzing test has been made
+ customizable with a new Makefile variable.
+
+ * The way "git rebase" parses and forwards the command line options
+ meant for underlying "git am" has been revamped, which fixed for
+ options with parameters that were not passed correctly.
+
+ * Our testing framework uses a special i18n "poisoned localization"
+ feature to find messages that ought to stay constant but are
+ incorrectly marked to be translated. This feature has been made
+ into a runtime option (it used to be a compile-time option).
+
+ * "git push" used to check ambiguities between object-names and
+ refnames while processing the list of refs' old and new values,
+ which was unnecessary (as it knew that it is feeding raw object
+ names). This has been optimized out.
+
+ * The xcurl_off_t() helper function is used to cast size_t to
+ curl_off_t, but some compilers gave warnings against the code to
+ ensure the casting is done without wraparound, when size_t is
+ narrower than curl_off_t. This warning has been squelched.
+
+ * Code preparation to replace ulong vars with size_t vars where
+ appropriate continues.
+
+ * The "test installed Git" mode of our test suite has been updated to
+ work better.
+
+ * A coding convention around the Coccinelle semantic patches to have
+ two classes to ease code migration process has been proposed and
+ its support has been added to the Makefile.
+
Fixes since v2.19
-----------------
pathspec elements were involved, which has been fixed.
(merge b7845cebc0 nd/tree-walk-path-exclusion later to maint).
+ * "git merge" and "git pull" that merges into an unborn branch used
+ to completely ignore "--verify-signatures", which has been
+ corrected.
+ (merge 01a31f3bca jk/verify-sig-merge-into-void later to maint).
+
+ * "git rebase --autostash" did not correctly re-attach the HEAD at times.
+
+ * "rev-parse --exclude=<pattern> --branches=<pattern>" etc. did not
+ quite work, which has been corrected.
+ (merge 9ab9b5df0e ra/rev-parse-exclude-glob later to maint).
+
+ * When editing a patch in a "git add -i" session, a hunk could be
+ made to no-op. The "git apply" program used to reject a patch with
+ such a no-op hunk to catch user mistakes, but it is now updated to
+ explicitly allow a no-op hunk in an edited patch.
+ (merge 22cb3835b9 js/apply-recount-allow-noop later to maint).
+
+ * The URL to an MSDN page in a comment has been updated.
+ (merge 2ef2ae2917 js/mingw-msdn-url later to maint).
+
+ * "git ls-remote --sort=<thing>" can feed an object that is not yet
+ available into the comparison machinery and segfault, which has
+ been corrected to check such a request upfront and reject it.
+
+ * When "git bundle" aborts due to an empty commit ranges
+ (i.e. resulting in an empty pack), it left a file descriptor to an
+ lockfile open, which resulted in leftover lockfile on Windows where
+ you cannot remove a file with an open file descriptor. This has
+ been corrected.
+ (merge 2c8ee1f53c jk/close-duped-fd-before-unlock-for-bundle later to maint).
+
+ * "git format-patch --stat=<width>" can be used to specify the width
+ used by the diffstat (shown in the cover letter).
+ (merge 284aeb7e60 nd/format-patch-cover-letter-stat-width later to maint).
+
+ * The way .git/index and .git/sharedindex* files were initially
+ created gave these files different perm bits until they were
+ adjusted for shared repository settings. This was made consistent.
+ (merge c9d6c78870 cc/shared-index-permbits later to maint).
+
* Code cleanup, docfix, build fix, etc.
