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
-------------------
necessary to go beyond the 4GB limit.
(merge 867e40ff3a rs/large-zip later to maint).
+ * "git reset" learned "--recurse-submodules" option.
+
+ * "git diff --submodule=diff" now recurses into nested submodules.
+ (merge 5a5221427c jk/diff-submodule-diff-inline later to maint).
+
+ * "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
* We can trigger Windows auto-build tester (credits: Dscho &
Microsoft) from our existing Travis CI tester now.
+ * 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.
+
+ * 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
+ future.
+ (merge de950c5773 nd/split-index-unshare later to maint).
+
+ * "pack-objects" can stream a slice of an existing packfile out when
+ the pack bitmap can tell that the reachable objects are all needed
+ 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.
+
+ * Fix memory leaks pointed out by Coverity (and people).
+
+ * "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.
+
+ * 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.
+
+ * Introduce the BUG() macro to improve die("BUG: ...").
+
+ * Clarify documentation for include.path and includeIf.<condition>.path
+ configuration variables.
+
+ * 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.
+
+ * A few http:// links that are redirected to https:// in the
+ documentation have been updated to https:// links.
+
+ * "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.
+
+ * Regression fix to topic recently merged to 'master'.
+
+ * The shell completion script (in contrib/) learned "git stash" has
+ a new "push" subcommand.
+
+ * "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.
+
+ * 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
+ that allows atomically appending to a file opened with O_APPEND,
+ 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.
+
+ * 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)
+
+ * "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).
