Git 2.15 Release Notes
|
|
======================
|
|
|
|
Backward compatibility notes and other notable changes.
|
|
|
|
* Use of an empty string as a pathspec element that is used for
|
|
'everything matches' is still warned and Git asks users to use a
|
|
more explicit '.' for that instead. The hope is that existing
|
|
users will not mind this change, and eventually the warning can be
|
|
turned into a hard error, upgrading the deprecation into removal of
|
|
this (mis)feature. That is now scheduled to happen in the upcoming
|
|
release.
|
|
|
|
* Git now avoids blindly falling back to ".git" when the setup
|
|
sequence said we are _not_ in Git repository. A corner case that
|
|
happens to work right now may be broken by a call to die("BUG").
|
|
We've tried hard to locate such cases and fixed them, but there
|
|
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
|
|
-------------------
|
|
|
|
UI, Workflows & Features
|
|
|
|
* An example that is now obsolete has been removed from a sample hook,
|
|
and an old example in it that added a sign-off manually has been
|
|
improved to use the interpret-trailers command.
|
|
|
|
* The advice message given when "git rebase" stops for conflicting
|
|
changes has been improved.
|
|
|
|
* The "rerere-train" script (in contrib/) learned the "--overwrite"
|
|
option to allow overwriting existing recorded resolutions.
|
|
|
|
* "git contacts" (in contrib/) now lists the address on the
|
|
"Reported-by:" trailer to its output, in addition to those on
|
|
S-o-b: and other trailers, to make it easier to notify (and thank)
|
|
the original bug reporter.
|
|
|
|
* "git rebase", especially when it is run by mistake and ends up
|
|
trying to replay many changes, spent long time in silence. The
|
|
command has been taught to show progress report when it spends
|
|
long time preparing these many changes to replay (which would give
|
|
the user a chance to abort with ^C).
|
|
|
|
* "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.
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
|
|
* Conversion from uchar[20] to struct object_id continues.
|
|
|
|
* Start using selected c99 constructs in small, stable and
|
|
essentialpart of the system to catch people who care about
|
|
older compilers that do not grok them.
|
|
|
|
* The filter-process interface learned to allow a process with long
|
|
latency give a "delayed" response.
|
|
|
|
* Many uses of comparision callback function the hashmap API uses
|
|
cast the callback function type when registering it to
|
|
hashmap_init(), which defeats the compile time type checking when
|
|
the callback interface changes (e.g. gaining more parameters).
|
|
The callback implementations have been updated to take "void *"
|
|
pointers and cast them to the type they expect instead.
|
|
|
|
* Because recent Git for Windows do come with a real msgfmt, the
|
|
build procedure for git-gui has been updated to use it instead of a
|
|
hand-rolled substitute.
|
|
|
|
* "git grep --recurse-submodules" has been reworked to give a more
|
|
consistent output across submodule boundary (and do its thing
|
|
without having to fork a separate process).
|
|
|
|
* A helper function to read a single whole line into strbuf
|
|
mistakenly triggered OOM error at EOF under certain conditions,
|
|
which has been fixed.
|
|
(merge 642956cf45 rs/strbuf-getwholeline-fix later to maint).
|
|
|
|
* The "ref-store" code reorganization continues.
|
|
|
|
* "git commit" used to discard the index and re-read from the filesystem
|
|
just in case the pre-commit hook has updated it in the middle; this
|
|
has been optimized out when we know we do not run the pre-commit hook.
|
|
(merge 680ee550d7 kw/commit-keep-index-when-pre-commit-is-not-run later to maint).
|
|
|
|
* Updates to the HTTP layer we made recently unconditionally used
|
|
features of libCurl without checking the existence of them, causing
|
|
compilation errors, which has been fixed. Also migrate the code to
|
|
check feature macros, not version numbers, to cope better with
|
|
libCurl that vendor ships with backported features.
|
|
|
|
* The API to start showing progress meter after a short delay has
|
|
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.
|
|
|
|
|
|
Also contains various documentation updates and code clean-ups.
|
|
|
|
|
|
Fixes since v2.14
|
|
-----------------
|
|
|
|
* "%C(color name)" in the pretty print format always produced ANSI
|
|
color escape codes, which was an early design mistake. They now
|
|
honor the configuration (e.g. "color.ui = never") and also tty-ness
|
|
of the output medium.
|
|
|
|
* The http.{sslkey,sslCert} configuration variables are to be
|
|
interpreted as a pathname that honors "~[username]/" prefix, but
|
|
weren't, which has been fixed.
|
|
|
|
* Numerous bugs in walking of reflogs via "log -g" and friends have
|
|
been fixed.
|
|
|
|
* "git commit" when seeing an totally empty message said "you did not
|
|
edit the message", which is clearly wrong. The message has been
|
|
corrected.
|
|
|
|
* When a directory is not readable, "gitweb" fails to build the
|
|
project list. Work this around by skipping such a directory.
|
|
|
|
* 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.
|
|
|
|
* A recently added test for the "credential-cache" helper revealed
|
|
that EOF detection done around the time the connection to the cache
|
|
daemon is torn down were flaky. This was fixed by reacting to
|
|
ECONNRESET and behaving as if we got an EOF.
|
|
|
|
* "git log --tag=no-such-tag" showed log starting from HEAD, which
|
|
has been fixed---it now shows nothing.
|
|
|
|
* 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.
|
|
|
|
* "git push --recurse-submodules $there HEAD:$target" was not
|
|
propagated down to the submodules, but now it is.
|
|
|
|
* Commands like "git rebase" accepted the --rerere-autoupdate option
|
|
from the command line, but did not always use it. This has been
|
|
fixed.
|
|
|
|
* "git clone --recurse-submodules --quiet" did not pass the quiet
|
|
option down to submodules.
|
|
|
|
* Test portability fix for OBSD.
|
|
|
|
* Portability fix for OBSD.
|
|
|
|
* "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.
|
|
|
|
* "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.
|
|
|
|
* Memory leak in an error codepath has been plugged.
|
|
|
|
* "git stash -u" used the contents of the committed version of the
|
|
".gitignore" file to decide which paths are ignored, even when the
|
|
file has local changes. The command has been taught to instead use
|
|
the locally modified contents.
|
|
|
|
* bash 4.4 or newer gave a warning on NUL byte in command
|
|
substitution done in "git stash"; this has been squelched.
|
|
|
|
* "git grep -L" and "git grep --quiet -L" reported different exit
|
|
codes; this has been corrected.
|
|
|
|
* 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.
|
|
|
|
* "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).
|
|
|
|
* Other minor doc, test and build updates and code cleanups.
|
|
(merge f094b89a4d ma/parse-maybe-bool later to maint).
|
