might still be cases that need to be addressed--bug reports are
greatly appreciated.
+ * The experiment to improve the hunk-boundary selection of textual
+ diff output has finished, and the "indent heuristics" has now
+ become the default.
+
Updates since v2.13
-------------------
* "git repack" learned to accept the --threads=<n> option and pass it
to pack-objects.
+ * "git send-email" learned to run sendemail-validate hook to inspect
+ and reject a message before sending it out.
+ (merge 177409e589 jt/send-email-validate-hook later to maint).
+
+ * There is no good reason why "git fetch $there $sha1" should fail
+ when the $sha1 names an object at the tip of an advertised ref,
+ even when the other side hasn't enabled allowTipSHA1InWant.
+
+ * The recently introduced "[includeIf "gitdir:$dir"] path=..."
+ mechansim has further been taught to take symlinks into account.
+ The directory "$dir" specified in "gitdir:$dir" may be a symlink to
+ a real location, not something that $(getcwd) may return. In such
+ a case, a realpath of "$dir" is compared with the real path of the
+ current repository to determine if the contents from the named path
+ should be included.
+
+ * Make the "indent" heuristics the default in "diff" and diff.indentHeuristics
+ configuration variable an escape hatch for those who do no want it.
+
+ * Many commands learned to pay attention to submodule.recurse
+ configuration.
+
+ * The convention for a command line is to follow "git cmdname
+ --options" with revisions followed by an optional "--"
+ disambiguator and then finally pathspecs. When "--" is not there,
+ we make sure early ones are all interpretable as revs (and do not
+ look like paths) and later ones are the other way around. A
+ pathspec with "magic" (e.g. ":/p/a/t/h" that matches p/a/t/h from
+ the top-level of the working tree, no matter what subdirectory you
+ are working from) are conservatively judged as "not a path", which
+ required disambiguation more often. The command line parser
+ learned to say "it's a pathspec" a bit more often when the syntax
+ looks like so.
+ (merge 2cb47ab695 jk/pathspec-magic-disambiguation later to maint).
+
+ * Update "perl-compatible regular expression" support to enable JIT
+ and also allow linking with the newer PCRE v2 library.
+
Performance, Internal Implementation, Development Support etc.
* Travis CI gained a task to format the documentation with both
AsciiDoc and AsciiDoctor.
- (merge 505ad91304 ls/travis-doc-asciidoctor later to maint).
* Some platforms have ulong that is smaller than time_t, and our
historical use of ulong for timestamp would mean they cannot
* Conversion from uchar[20] to struct object_id continues.
+ * Simplify parse_pathspec() codepath and stop it from looking at the
+ default in-core index.
+ (merge 08de9151a8 bw/pathspec-sans-the-index later to maint).
+
+ * Add perf-test for wildmatch.
+ (merge 62ca75a6b9 ab/perf-wildmatch later to maint).
+
+ * Code from "conversion using external process" codepath has been
+ extracted to a separate sub-process.[ch] module.
+ (merge 4f2a2e9f0e bp/sub-process-convert-filter later to maint).
+
+ * When "git checkout", "git merge", etc. manipulates the in-core
+ index, various pieces of information in the index extensions are
+ discarded from the original state, as it is usually not the case
+ that they are kept up-to-date and in-sync with the operation on the
+ main index. The untracked cache extension is copied across these
+ operations now, which would speed up "git status" (as long as the
+ cache is properly invalidated).
+
+ * The internal implementation of "git grep" has seen some clean-up.
+ (merge 8df4c2953f ab/grep-preparatory-cleanup later to maint).
+
+ * Update the C style recommendation for notes for translators, as
+ recent versions of gettext tools can work with our style of
+ multi-line comments.
+
+ * The implementation of "ref" API around the "packed refs" have been
+ cleaned up, in preparation for further changes.
+
+ * The internal logic used in "git blame" has been libified to make it
+ easier to use by cgit.
+
+ * Our code often opens a path to an optional file, to work on its
+ contents when we can successfully open it. We can ignore a failure
+ to open if such an optional file does not exist, but we do want to
+ report a failure in opening for other reasons (e.g. we got an I/O
+ error, or the file is there, but we lack the permission to open).
+
+ The exact errors we need to ignore are ENOENT (obviously) and
+ ENOTDIR (less obvious). Instead of repeating comparison of errno
+ with these two constants, introduce a helper function to do so.
+
+ * We often try to open a file for reading whose existence is
+ optional, and silently ignore errors from open/fopen; report such
+ errors if they are not due to missing files.
+
+ * When an existing repository is used for t/perf testing, we first
+ create bit-for-bit copy of it, which may grab a transient state of
+ the repository and freeze it into the repository used for testing,
+ which then may cause Git operations to fail. Single out "the index
+ being locked" case and forcibly drop the lock from the copy.
Also contains various documentation updates and code clean-ups.
mishandled a trailer block whose last line is an incomplete line.
This has been fixed so that an additional sign-off etc. are added
after completing the existing incomplete line.
- (merge 44dc738a39 jt/use-trailer-api-in-commands later to maint).
* The codepath in "git am" that is used when running "git rebase"
leaked memory held for the log message of the commits being rebased.
- (merge 721f5f1e35 jk/am-leakfix later to maint).
* "git clone --config var=val" is a way to populate the
per-repository configuration file of the new repository, but it did
not work well when val is an empty string. This has been fixed.
- (merge db4eca1fea jn/clone-add-empty-config-from-command-line later to maint).
* Setting "log.decorate=false" in the configuration file did not take
effect in v2.13, which has been corrected.
- (merge c74271aae7 ah/log-decorate-default-to-auto later to maint).
* A few codepaths in "checkout" and "am" working on an unborn branch
tried to access an uninitialized piece of memory.
- (merge 57e0ef0e0e rs/checkout-am-fix-unborn later to maint).
* The Web interface to gmane news archive is long gone, even though
the articles are still accessible via NTTP. Replace the links with
ones to public-inbox.org. Because their message identification is
based on the actual message-id, it is likely that it will be easier
to migrate away from it if/when necessary.
- (merge 5840eb9d14 ab/doc-replace-gmane-links later to maint).
* The receive-pack program now makes sure that the push certificate
records the same set of push options used for pushing.
- (merge cbaf82cc6b jt/push-options-doc later to maint).
* Tests have been updated to pass under GETTEXT_POISON (a mechanism
to ensure that output strings that should not be translated are
not translated by mistake), and TravisCI is told to run them.
- (merge b8e188f6f5 ab/fix-poison-tests later to maint).
* "git checkout --recurse-submodules" did not quite work with a
submodule that itself has submodules.
- (merge 218c883783 sb/checkout-recurse-submodules later to maint).
* Plug some leaks and updates internal API used to implement the
split index feature to make it easier to avoid such a leak in the
in the output, without inspecting individual objects. This
strategy however would not work well when "--local" and other
options are in use, and need to be disabled.
- (merge da5a1f8100 jk/disable-pack-reuse-when-broken later to maint).
* Fix memory leaks pointed out by Coverity (and people).
- (merge 443a12f37b js/plug-leaks later to maint).
* "git read-tree -m" (no tree-ish) gave a nonsense suggestion "use
--empty if you want to clear the index". With "-m", such a request
will still fail anyway, as you'd need to name at least one tree-ish
to be merged.
- (merge b9b10d3681 jc/read-tree-empty-with-m later to maint).
* Make sure our tests would pass when the sources are checked out
with "platform native" line ending convention by default on
Windows. Some "text" files out tests use and the test scripts
themselves that are meant to be run with /bin/sh, ought to be
checked out with eol=LF even on Windows.
- (merge 2779f66505 js/eol-on-ourselves later to maint).
* Introduce the BUG() macro to improve die("BUG: ...").
- (merge 3d7dd2d3b6 jk/bug-to-abort later to maint).
* Clarify documentation for include.path and includeIf.<condition>.path
configuration variables.
- (merge ce933ebd5a jk/doc-config-include later to maint).
* Git sometimes gives an advice in a rhetorical question that does
not require an answer, which can confuse new users and non native
speakers. Attempt to rephrase them.
- (merge 6963893943 ja/do-not-ask-needless-questions later to maint).
* A few http:// links that are redirected to https:// in the
documentation have been updated to https:// links.
- (merge 5e68729fd9 jk/update-links-in-docs later to maint).
* "git for-each-ref --format=..." with %(HEAD) in the format used to
resolve the HEAD symref as many times as it had processed refs,
which was wasteful, and "git branch" shared the same problem.
- (merge 613a0e52ea kn/ref-filter-branch-list later to maint).
* Regression fix to topic recently merged to 'master'.
- (merge d096d7f1ef pw/rebase-i-regression-fix later to maint).
* The shell completion script (in contrib/) learned "git stash" has
a new "push" subcommand.
- (merge 3851e4483f tg/stash-push-fixup later to maint).
* "git interpret-trailers", when used as GIT_EDITOR for "git commit
-v", looked for and appended to a trailer block at the very end,
i.e. at the end of the "diff" output. The command has been
corrected to pay attention to the cut-mark line "commit -v" adds to
the buffer---the real trailer block should appear just before it.
- (merge d76650b8d1 bm/interpret-trailers-cut-line-is-eom later to maint).
* A test allowed both "git push" and "git receive-pack" on the other
end write their traces into the same file. This is OK on platforms
but on other platforms led to a mangled output, causing
intermittent test failures. This has been fixed by disabling
traces from "receive-pack" in the test.
- (merge 71406ed4d6 jk/alternate-ref-optim later to maint).
* Tag objects, which are not reachable from any ref, that point at
missing objects were mishandled by "git gc" and friends (they
should silently be ignored instead)
- (merge a3ba6bf10a jk/ignore-broken-tags-when-ignoring-missing-links later to maint).
+
+ * "git describe --contains" penalized light-weight tags so much that
+ they were almost never considered. Instead, give them about the
+ same chance to be considered as an annotated tag that is the same
+ age as the underlying commit would.
+ (merge ef1e74065c jc/name-rev-lw-tag later to maint).
+
+ * The "run-command" API implementation has been made more robust
+ against dead-locking in a threaded environment.
+
+ * A recent update to t5545-push-options.sh started skipping all the
+ tests in the script when a web server testing is disabled or
+ unavailable, not just the ones that require a web server. Non HTTP
+ tests have been salvaged to always run in this script.
+
+ * "git send-email" now uses Net::SMTP::SSL, which is obsolete, only
+ when needed. Recent versions of Net::SMTP can do TLS natively.
+
+ * "foo\bar\baz" in "git fetch foo\bar\baz", even though there is no
+ slashes in it, cannot be a nickname for a remote on Windows, as
+ that is likely to be a pathname on a local filesystem.
+
+ * "git clean -d" used to clean directories that has ignored files,
+ even though the command should not lose ignored ones without "-x".
+ "git status --ignored" did not list ignored and untracked files
+ without "-uall". These have been corrected.
+
+ * The result from "git diff" that compares two blobs, e.g. "git diff
+ $commit1:$path $commit2:$path", used to be shown with the full
+ object name as given on the command line, but it is more natural to
+ use the $path in the output and use it to look up .gitattributes.
+ (merge 30d005c020 jk/diff-blob later to maint).
+
+ * The "collision detecting" SHA-1 implementation shipped with 2.13
+ was quite broken on some big-endian platforms and/or platforms that
+ do not like unaligned fetches. Update to the upstream code which
+ has already fixed these issues.
+
+ * "git am -h" triggered a BUG().
+
+ * The interaction of "url.*.insteadOf" and custom URL scheme's
+ whitelisting is now documented better.
+
+ * The timestamp of the index file is now taken after the file is
+ closed, to help Windows, on which a stale timestamp is reported by
+ fstat() on a file that is opened for writing and data was written
+ but not yet closed.
+
+ * "git pull --rebase --autostash" didn't auto-stash when the local history
+ fast-forwards to the upstream.
+
+ * A flaky test has been corrected.
+ (merge 7c2115aa07 jk/pack-idx-corruption-safety later to maint).
+
+ * "git $cmd -h" for builtin commands calls the implementation of the
+ command (i.e. cmd_$cmd() function) without doing any repository
+ set-up, and the commands that expect RUN_SETUP is done by the Git
+ potty needs to be prepared to show the help text without barfing.
+ (merge d691551192 jk/consistent-h later to maint).
* Other minor doc, test and build updates and code cleanups.
