might still be cases that need to be addressed--bug reports are
greatly appreciated.
+ * "branch --set-upstream" that has been deprecated in Git 1.8 has
+ finally been retired.
+
Updates since v2.14
-------------------
* "git merge" learned a "--signoff" option to add the Signed-off-by:
trailer with the committer's name.
+ * "git diff" learned to optionally paint new lines that are the same
+ as deleted lines elsewhere differently from genuinely new lines.
+
+ * "git interpret-trailers" learned to take the trailer specifications
+ from the command line that overrides the configured values.
+
+ * "git interpret-trailers" has been taught a "--parse" and a few
+ other options to make it easier for scripts to grab existing
+ trailer lines from a commit log message.
+
+ * "gitweb" shows a link to visit the 'raw' contents of blbos in the
+ history overview page.
+
+ * "[gc] rerereResolved = 5.days" used to be invalid, as the variable
+ is defined to take an integer counting the number of days. It now
+ is allowed.
+
+ * The code to acquire a lock on a reference (e.g. while accepting a
+ push from a client) used to immediately fail when the reference is
+ already locked---now it waits for a very short while and retries,
+ which can make it succeed if the lock holder was holding it during
+ a read-only operation.
+
+ * "branch --set-upstream" that has been deprecated in Git 1.8 has
+ finally been retired.
+
+ * The codepath to call external process filter for smudge/clean
+ operation learned to show the progress meter.
+
+ * "git rev-parse" learned "--is-shallow-repository", that is to be
+ used in a way similar to existing "--is-bare-repository" and
+ friends.
+
+ * "git describe --match <pattern>" has been taught to play well with
+ the "--all" option.
+
Performance, Internal Implementation, Development Support etc.
been simplified.
(merge 8aade107dd jc/simplify-progress later to maint).
+ * Code clean-up to avoid mixing values read from the .gitmodules file
+ and values read from the .git/config file.
+
+ * We used to spend more than necessary cycles allocating and freeing
+ piece of memory while writing each index entry out. This has been
+ optimized.
+
+ * Platforms that ship with a separate sha1 with collision detection
+ library can link to it instead of using the copy we ship as part of
+ our source tree.
+
+ * Code around "notes" have been cleaned up.
+ (merge 3964281524 mh/notes-cleanup later to maint).
+
+ * The long-standing rule that an in-core lockfile instance, once it
+ is used, must not be freed, has been lifted and the lockfile and
+ tempfile APIs have been updated to reduce the chance of programming
+ errors.
+
+ * Our hashmap implementation in hashmap.[ch] is not thread-safe when
+ adding a new item needs to expand the hashtable by rehashing; add
+ an API to disable the automatic rehashing to work it around.
+
+ * Many of our programs consider that it is OK to release dynamic
+ storage that is used throughout the life of the program by simply
+ exiting, but this makes it harder to leak detection tools to avoid
+ reporting false positives. Plug many existing leaks and introduce
+ a mechanism for developers to mark that the region of memory
+ pointed by a pointer is not lost/leaking to help these tools.
+
+ * As "git commit" to conclude a conflicted "git merge" honors the
+ commit-msg hook, "git merge" that records a merge commit that
+ cleanly auto-merges should, but it didn't.
+
+ * The codepath for "git merge-recursive" has been cleaned up.
+
+ * Many leaks of strbuf have been fixed.
+
+ * "git imap-send" has our own implementation of the protocol and also
+ can use more recent libCurl with the imap protocol support. Update
+ the latter so that it can use the credential subsystem, and then
+ make it the default option to use, so that we can eventually
+ deprecate and remove the former.
+
+ * "make style" runs git-clang-format to help developers by pointing
+ out coding style issues.
+
+ * A test to demonstrate "git mv" failing to adjust nested submodules
+ has been added.
+ (merge c514167df2 hv/mv-nested-submodules-test later to maint).
+
+ * On Cygwin, "ulimit -s" does not report failure but it does not work
+ at all, which causes an unexpected success of some tests that
+ expect failures under a limited stack situation. This has been
+ fixed.
+
+ * Many codepaths have been updated to squelch -Wimplicit-fallthrough
+ warnings from Gcc 7 (which is a good code hygiene).
+
+ * Add a helper for DLL loading in anticipation for its need in a
+ future topic RSN.
+
+ * "git status --ignored", when noticing that a directory without any
+ tracked path is ignored, still enumerated all the ignored paths in
+ the directory, which is unnecessary. The codepath has been
+ optimized to avoid this overhead.
+
Also contains various documentation updates and code clean-ups.
* Some versions of GnuPG fails to kill gpg-agent it auto-spawned
and such a left-over agent can interfere with a test. Work it
around by attempting to kill one before starting a new test.
- (merge 29ff1f8f74 st/lib-gpg-kill-stray-agent later to maint).
* A recently added test for the "credential-cache" helper revealed
that EOF detection done around the time the connection to the cache
* "git log --tag=no-such-tag" showed log starting from HEAD, which
has been fixed---it now shows nothing.
- (merge 5d34d1ac06 jk/rev-list-empty-input later to maint).
* The "tag.pager" configuration variable was useless for those who
actually create tag objects, as it interfered with the use of an
editor. A new mechanism has been introduced for commands to enable
pager depending on what operation is being carried out to fix this,
and then "git tag -l" is made to run pager by default.
- (merge 595d59e2b5 ma/pager-per-subcommand-action later to maint).
* "git push --recurse-submodules $there HEAD:$target" was not
propagated down to the submodules, but now it is.
- (merge c7be7201a7 bw/push-options-recursively-to-submodules later to maint).
* Commands like "git rebase" accepted the --rerere-autoupdate option
from the command line, but did not always use it. This has been
fixed.
- (merge f826fb799e pw/sequence-rerere-autoupdate later to maint).
* "git clone --recurse-submodules --quiet" did not pass the quiet
option down to submodules.
- (merge 03c004c581 bw/clone-recursive-quiet later to maint).
* Test portability fix for OBSD.
- (merge bed67874e2 rs/obsd-getcwd-workaround later to maint).
- (merge 4c7fda8fc1 rs/t4062-obsd later to maint).
* Portability fix for OBSD.
- (merge 29c2eda80b rs/in-obsd-basename-dirname-take-const later to maint).
* "git am -s" has been taught that some input may end with a trailer
block that is not Signed-off-by: and it should refrain from adding
an extra blank line before adding a new sign-off in such a case.
- (merge 735285b403 pw/am-signoff later to maint).
* "git svn" used with "--localtime" option did not compute the tz
offset for the timestamp in question and instead always used the
current time, which has been corrected.
- (merge 1adc4b9a58 ur/svn-local-zone later to maint).
* Memory leak in an error codepath has been plugged.
- (merge 83cd6f9017 rs/fsck-obj-leakfix later to maint).
- (merge 896dca3ab7 rs/unpack-entry-leakfix later to maint).
- (merge 149d8cbb2e rs/win32-syslog-leakfix later to maint).
* "git stash -u" used the contents of the committed version of the
".gitignore" file to decide which paths are ignored, even when the
* bash 4.4 or newer gave a warning on NUL byte in command
substitution done in "git stash"; this has been squelched.
- (merge 5fc92f8828 kd/stash-with-bash-4.4 later to maint).
* "git grep -L" and "git grep --quiet -L" reported different exit
codes; this has been corrected.
- (merge e1f68c66d5 as/grep-quiet-no-match-exit-code-fix later to maint).
* When handshake with a subprocess filter notices that the process
asked for an unknown capability, Git did not report what program
the offending subprocess was running. This has been corrected.
- (merge d3ba566342 cc/subprocess-handshake-missing-capabilities later to maint).
+
+ * "git apply" that is used as a better "patch -p1" failed to apply a
+ taken from a file with CRLF line endings to a file with CRLF line
+ endings. The root cause was because it misused convert_to_git()
+ that tried to do "safe-crlf" processing by looking at the index
+ entry at the same path, which is a nonsense---in that mode, "apply"
+ is not working on the data in (or derived from) the index at all.
+ This has been fixed.
+
+ * Killing "git merge --edit" before the editor returns control left
+ the repository in a state with MERGE_MSG but without MERGE_HEAD,
+ which incorrectly tells the subsequent "git commit" that there was
+ a squash merge in progress. This has been fixed.
+
+ * "git archive" did not work well with pathspecs and the
+ export-ignore attribute.
+
+ * In addition to "cc: <a@dd.re.ss> # cruft", "cc: a@dd.re.ss # cruft"
+ was taught to "git send-email" as a valid way to tell it that it
+ needs to also send a carbon copy to <a@dd.re.ss> in the trailer
+ section.
+ (merge cc90750677 mm/send-email-cc-cruft later to maint).
+
+ * "git branch -M a b" while on a branch that is completely unrelated
+ to either branch a or branch b misbehaved when multiple worktree
+ was in use. This has been fixed.
+ (merge 31824d180d nd/worktree-kill-parse-ref later to maint).
+
+ * "git gc" and friends when multiple worktrees are used off of a
+ single repository did not consider the index and per-worktree refs
+ of other worktrees as the root for reachability traversal, making
+ objects that are in use only in other worktrees to be subject to
+ garbage collection.
+
+ * A regression to "gitk --bisect" by a recent update has been fixed.
+ (merge 1d0538e486 mh/packed-ref-store-prep later to maint).
+
+ * "git -c submodule.recurse=yes pull" did not work as if the
+ "--recurse-submodules" option was given from the command line.
+ This has been corrected.
+
+ * Unlike "git commit-tree < file", "git commit-tree -F file" did not
+ pass the contents of the file verbatim and instead completed an
+ incomplete line at the end, if exists. The latter has been updated
+ to match the behaviour of the former.
+ (merge c818e74332 rk/commit-tree-make-F-verbatim later to maint).
+
+ * Many codepaths did not diagnose write failures correctly when disks
+ go full, due to their misuse of write_in_full() helper function,
+ which have been corrected.
+ (merge f48ecd38cb jk/write-in-full-fix later to maint).
+
+ * "git help co" now says "co is aliased to ...", not "git co is".
+ (merge b3a8076e0d ks/help-alias-label later to maint).
+
+ * "git archive", especially when used with pathspec, stored an empty
+ directory in its output, even though Git itself never does so.
+ This has been fixed.
+ (merge 4318094047 rs/archive-excluded-directory later to maint).
+
+ * API error-proofing which happens to also squelch warnings from GCC.
+ (merge c788c54cde tg/refs-allowed-flags later to maint).
+
+ * The explanation of the cut-line in the commit log editor has been
+ slightly tweaked.
+ (merge 8c4b1a3593 ks/commit-do-not-touch-cut-line later to maint).
+
+ * "git gc" tries to avoid running two instances at the same time by
+ reading and writing pid/host from and to a lock file; it used to
+ use an incorrect fscanf() format when reading, which has been
+ corrected.
+ (merge afe2fab72c aw/gc-lockfile-fscanf-fix later to maint).
+
+ * The scripts to drive TravisCI has been reorganized and then an
+ optimization to avoid spending cycles on a branch whose tip is
+ tagged has been implemented.
+ (merge 8376eb4a8f ls/travis-scriptify later to maint).
+
+ * The test linter has been taught that we do not like "echo -e".
+ (merge 1a6d46895d tb/test-lint-echo-e later to maint).
+
+ * Code cmp.std.c nitpick.
+ (merge ac7da78ede mh/for-each-string-list-item-empty-fix later to maint).
+
+ * A regression fix for 2.11 that made the code to read the list of
+ alternate object stores overrun the end of the string.
+ (merge f0f7bebef7 jk/info-alternates-fix later to maint).
+
+ * "git describe --match" learned to take multiple patterns in v2.13
+ series, but the feature ignored the patterns after the first one
+ and did not work at all. This has been fixed.
+ (merge da769d2986 jk/describe-omit-some-refs later to maint).
+
+ * "git filter-branch" cannot reproduce a history with a tag without
+ the tagger field, which only ancient versions of Git allowed to be
+ created. This has been corrected.
+ (merge b2c1ca6b4b ic/fix-filter-branch-to-handle-tag-without-tagger later to maint).
+
+ * "git cat-file --textconv" started segfaulting recently, which
+ has been corrected.
+ (merge cc0ea7c9e5 jk/diff-blob later to maint).
+
+ * The built-in pattern to detect the "function header" for HTML did
+ not match <H1>..<H6> elements without any attributes, which has
+ been fixed.
+ (merge 9c03caca2c ik/userdiff-html-h-element-fix later to maint).
+
+ * "git mailinfo" was loose in decoding quoted printable and produced
+ garbage when the two letters after the equal sign are not
+ hexadecimal. This has been fixed.
+ (merge c8cf423eab rs/mailinfo-qp-decode-fix later to maint).
+
+ * The machinery to create xdelta used in pack files received the
+ sizes of the data in size_t, but lost the higher bits of them by
+ storing them in "unsigned int" during the computation, which is
+ fixed.
+
+ * The delta format used in the packfile cannot reference data at
+ offset larger than what can be expressed in 4-byte, but the
+ generator for the data failed to make sure the offset does not
+ overflow. This has been corrected.
+
+ * The documentation for '-X<option>' for merges was misleadingly
+ written to suggest that "-s theirs" exists, which is not the case.
+ (merge c25d98b2a7 jc/merge-x-theirs-docfix later to maint).
+
+ * "git fast-export" with -M/-C option issued "copy" instruction on a
+ path that is simultaneously modified, which was incorrect.
+ (merge b3e8ca89cf jt/fast-export-copy-modify-fix later to maint).
+
+ * Many codepaths have been updated to squelch -Wsign-compare
+ warnings.
+ (merge 071bcaab64 rj/no-sign-compare later to maint).
+
+ * Memory leaks in various codepaths have been plugged.
+ (merge 4d01a7fa65 ma/leakplugs later to maint).
* Other minor doc, test and build updates and code cleanups.
