Git 2.23 Release Notes
======================
Updates since v2.22
-------------------
Backward compatibility note
* The "--base" option of "format-patch" computed the patch-ids for
prerequisite patches in an unstable way, which has been updated to
compute in a way that is compatible with "git patch-id --stable".
* The "git log" command by default behaves as if the --mailmap option
was given.
UI, Workflows & Features
* The "git fast-export/import" pair has been taught to handle commits
with log messages in encoding other than UTF-8 better.
* In recent versions of Git, per-worktree refs are exposed in
refs/worktrees/<wtname>/ hierarchy, which means that worktree names
must be a valid refname component. The code now sanitizes the names
given to worktrees, to make sure these refs are well-formed.
* "git merge" learned "--quit" option that cleans up the in-progress
merge while leaving the working tree and the index still in a mess.
* "git format-patch" learns a configuration to set the default for
its --notes=<ref> option.
* The code to show args with potential typo that cannot be
interpreted as a commit-ish has been improved.
* "git clone --recurse-submodules" learned to set up the submodules
to ignore commit object names recorded in the superproject gitlink
and instead use the commits that happen to be at the tip of the
remote-tracking branches from the get-go, by passing the new
"--remote-submodules" option.
* The pattern "git diff/grep" use to extract funcname and words
boundary for Matlab has been extend to cover Octave, which is more
or less equivalent.
* "git help git" was hard to discover (well, at least for some
people).
* The pattern "git diff/grep" use to extract funcname and words
boundary for Rust has been added.
* "git status" can be told a non-standard default value for the
"--[no-]ahead-behind" option with a new configuration variable
status.aheadBehind.
* "git fetch" and "git pull" reports when a fetch results in
non-fast-forward updates to let the user notice unusual situation.
The commands learned "--no-show-forced-updates" option to disable
this safety feature.
* Two new commands "git switch" and "git restore" are introduced to
split "checking out a branch to work on advancing its history" and
"checking out paths out of the index and/or a tree-ish to work on
advancing the current history" out of the single "git checkout"
command.
* "git branch --list" learned to always output the detached HEAD as
the first item (when the HEAD is detached, of course), regardless
of the locale.
* The conditional inclusion mechanism learned to base the choice on
the branch the HEAD currently is on.
* "git rev-list --objects" learned the "--no-object-names" option to
squelch the path to the object that is used as a grouping hint for
pack-objects.
* A new tag.gpgSign configuration variable turns "git tag -a" into
"git tag -s".
* "git multi-pack-index" learned expire and repack subcommands.
* "git blame" learned to "ignore" commits in the history, whose
effects (as well as their presence) get ignored.
* "git cherry-pick/revert" learned a new "--skip" action.
* The tips of refs from the alternate object store can be used as
starting point for reachability computation now.
* Extra blank lines in "git status" output have been reduced.
* The commits in a repository can be described by multiple
commit-graph files now, which allows the commit-graph files to be
updated incrementally.
* "git range-diff" output has been tweaked for easier identification
of which part of what file the patch shown is about.
Performance, Internal Implementation, Development Support etc.
* Update supporting parts of "git rebase" to remove code that should
no longer be used.
* Developer support to emulate unsatisfied prerequisites in tests to
ensure that the remainder of the tests still succeeds when tests
with prerequisites are skipped.
* "git update-server-info" learned not to rewrite the file with the
same contents.
* The way of specifying the path to find dynamic libraries at runtime
has been simplified. The old default to pass -R/path/to/dir has been
replaced with the new default to pass -Wl,-rpath,/path/to/dir,
which is the more recent GCC uses. Those who need to build with an
old GCC can still use "CC_LD_DYNPATH=-R"
* Prepare use of reachability index in topological walker that works
on a range (A..B).
* A new tutorial targeting specifically aspiring git-core
developers has been added.
* Auto-detect how to tell HP-UX aCC where to use dynamically linked
libraries from at runtime.
* "git mergetool" and its tests now spawn fewer subprocesses.
* Dev support update to help tracing out tests.
* Support to build with MSVC has been updated.
* "git fetch" that grabs from a group of remotes learned to run the
auto-gc only once at the very end.
* A handful of Windows build patches have been upstreamed.
* The code to read state files used by the sequencer machinery for
"git status" has been made more robust against a corrupt or stale
state files.
* "git for-each-ref" with multiple patterns have been optimized.
* The tree-walk API learned to pass an in-core repository
instance throughout more codepaths.
* When one step in multi step cherry-pick or revert is reset or
committed, the command line prompt script failed to notice the
current status, which has been improved.
* Many GIT_TEST_* environment variables control various aspects of
how our tests are run, but a few followed "non-empty is true, empty
or unset is false" while others followed the usual "there are a few
ways to spell true, like yes, on, etc., and also ways to spell
false, like no, off, etc." convention.
* Adjust the dir-iterator API and apply it to the local clone
optimization codepath.
* We have been trying out a few language features outside c89; the
coding guidelines document did not talk about them and instead had
a blanket ban against them.
* A test helper has been introduced to optimize preparation of test
repositories with many simple commits, and a handful of test
scripts have been updated to use it.
Fixes since v2.22
-----------------
* A relative pathname given to "git init --template=<path> <repo>"
ought to be relative to the directory "git init" gets invoked in,
but it instead was made relative to the repository, which has been
corrected.
* "git worktree add" used to fail when another worktree connected to
the same repository was corrupt, which has been corrected.
* The ownership rule for the file descriptor to fast-import remote
backend was mixed up, leading to an unrelated file descriptor getting
closed, which has been fixed.
* A "merge -c" instruction during "git rebase --rebase-merges" should
give the user a chance to edit the log message, even when there is
otherwise no need to create a new merge and replace the existing
one (i.e. fast-forward instead), but did not. Which has been
corrected.
* Code cleanup and futureproof.
* More parameter validation.
* "git update-server-info" used to leave stale packfiles in its
output, which has been corrected.
* The server side support for "git fetch" used to show incorrect
value for the HEAD symbolic ref when the namespace feature is in
use, which has been corrected.
* "git am -i --resolved" segfaulted after trying to see a commit as
if it were a tree, which has been corrected.
* "git bundle verify" needs to see if prerequisite objects exist in
the receiving repository, but the command did not check if we are
in a repository upfront, which has been corrected.
* "git merge --squash" is designed to update the working tree and the
index without creating the commit, and this cannot be countermanded
by adding the "--commit" option; the command now refuses to work
when both options are given.
* The data collected by fsmonitor was not properly written back to
the on-disk index file, breaking t7519 tests occasionally, which
has been corrected.
* Update to Unicode 12.1 width table.
* The command line to invoke a "git cat-file" command from inside
"git p4" was not properly quoted to protect a caret and running a
broken command on Windows, which has been corrected.
* "git request-pull" learned to warn when the ref we ask them to pull
from in the local repository and in the published repository are
different.
* When creating a partial clone, the object filtering criteria is
recorded for the origin of the clone, but this incorrectly used a
hardcoded name "origin" to name that remote; it has been corrected
to honor the "--origin <name>" option.
* "git fetch" into a lazy clone forgot to fetch base objects that are
necessary to complete delta in a thin packfile, which has been
corrected.
* The filter_data used in the list-objects-filter (which manages a
lazily sparse clone repository) did not use the dynamic array API
correctly---'nr' is supposed to point at one past the last element
of the array in use. This has been corrected.
* The description about slashes in gitignore patterns (used to
indicate things like "anchored to this level only" and "only
matches directories") has been revamped.
* The URL decoding code has been updated to avoid going past the end
of the string while parsing %-<hex>-<hex> sequence.
* The list of for-each like macros used by clang-format has been
updated.
* "git branch --list" learned to show branches that are checked out
in other worktrees connected to the same repository prefixed with
'+', similar to the way the currently checked out branch is shown
with '*' in front.
(merge 6e9381469e nb/branch-show-other-worktrees-head later to maint).
* Code restructuring during 2.20 period broke fetching tags via
"import" based transports.
* The commit-graph file is now part of the "files that the runtime
may keep open file descriptors on, all of which would need to be
closed when done with the object store", and the file descriptor to
an existing commit-graph file now is closed before "gc" finalizes a
new instance to replace it.
* "git checkout -p" needs to selectively apply a patch in reverse,
which did not work well.
* Code clean-up to avoid signed integer wraparounds during binary search.
* "git interpret-trailers" always treated '#' as the comment
character, regardless of core.commentChar setting, which has been
corrected.
* "git stash show 23" used to work, but no more after getting
rewritten in C; this regression has been corrected.
* "git rebase --abort" used to leave refs/rewritten/ when concluding
"git rebase -r", which has been corrected.
* An incorrect list of options was cached after command line
completion failed (e.g. trying to complete a command that requires
a repository outside one), which has been corrected.
* The code to parse scaled numbers out of configuration files has
been made more robust and also easier to follow.
* The codepath to compute delta islands used to spew progress output
without giving the callers any way to squelch it, which has been
fixed.
* Protocol capabilities that go over wire should never be translated,
but it was incorrectly marked for translation, which has been
corrected. The output of protocol capabilities for debugging has
been tweaked a bit.
* Use "Erase in Line" CSI sequence that is already used in the editor
support to clear cruft in the progress output.
* "git submodule foreach" did not protect command line options passed
to the command to be run in each submodule correctly, when the
"--recursive" option was in use.
* The configuration variable rebase.rescheduleFailedExec should be
effective only while running an interactive rebase and should not
affect anything when running a non-interactive one, which was not
the case. This has been corrected.
* The "git clone" documentation refers to command line options in its
description in the short form; they have been replaced with long
forms to make them more recognisable.
* Generation of pack bitmaps are now disabled when .keep files exist,
as these are mutually exclusive features.
(merge 7328482253 ew/repack-with-bitmaps-by-default later to maint).
* "git rm" to resolve a conflicted path leaked an internal message
"needs merge" before actually removing the path, which was
confusing. This has been corrected.
* "git stash --keep-index" did not work correctly on paths that have
been removed, which has been fixed.
(merge b932f6a5e8 tg/stash-keep-index-with-removed-paths later to maint).
* Window 7 update ;-)
* A codepath that reads from GPG for signed object verification read
past the end of allocated buffer, which has been fixed.
* "git clean" silently skipped a path when it cannot lstat() it; now
it gives a warning.
* "git push --atomic" that goes over the transport-helper (namely,
the smart http transport) failed to prevent refs to be pushed when
it can locally tell that one of the ref update will fail without
having to consult the other end, which has been corrected.
* The internal diff machinery can be made to read out of bounds while
looking for --function-context line in a corner case, which has been
corrected.
(merge b777f3fd61 jk/xdiff-clamp-funcname-context-index later to maint).
* Other code cleanup, docfix, build fix, etc.
(merge fbec05c210 cc/test-oidmap later to maint).
(merge 7a06fb038c jk/no-system-includes-in-dot-c later to maint).
(merge 81ed2b405c cb/xdiff-no-system-includes-in-dot-c later to maint).
(merge d61e6ce1dd sg/fsck-config-in-doc later to maint).
Git 2.19 Release Notes
Updates since v2.18
-------------------
UI, Workflows & Features
* "git diff" compares the index and the working tree. For paths
added with intent-to-add bit, the command shows the full contents
of them as added, but the paths themselves were not marked as new
files. They are now shown as new by default.
"git apply" learned the "--intent-to-add" option so that an
otherwise working-tree-only application of a patch will add new
paths to the index marked with the "intent-to-add" bit.
* "git grep" learned the "--column" option that gives not just the
line number but the column number of the hit.
* The "-l" option in "git branch -l" is an unfortunate short-hand for
"--create-reflog", but many users, both old and new, somehow expect
it to be something else, perhaps "--list". This step warns when "-l"
is used as a short-hand for "--create-reflog" and warns about the
future repurposing of the it when it is used.
* The userdiff pattern for .php has been updated.
* The content-transfer-encoding of the message "git send-email" sends
out by default was 8bit, which can cause trouble when there is an
overlong line to bust RFC 5322/2822 limit. A new option 'auto' to
automatically switch to quoted-printable when there is such a line
in the payload has been introduced and is made the default.
* "git checkout" and "git worktree add" learned to honor
checkout.defaultRemote when auto-vivifying a local branch out of a
remote tracking branch in a repository with multiple remotes that
have tracking branches that share the same names.
(merge 8d7b558bae ab/checkout-default-remote later to maint).
* "git grep" learned the "--only-matching" option.
* "git rebase --rebase-merges" mode now handles octopus merges as
well.
* Add a server-side knob to skip commits in exponential/fibbonacci
stride in an attempt to cover wider swath of history with a smaller
number of iterations, potentially accepting a larger packfile
transfer, instead of going back one commit a time during common
ancestor discovery during the "git fetch" transaction.
(merge 42cc7485a2 jt/fetch-negotiator-skipping later to maint).
* A new configuration variable core.usereplacerefs has been added,
primarily to help server installations that want to ignore the
replace mechanism altogether.
* Teach "git tag -s" etc. a few configuration variables (gpg.format
that can be set to "openpgp" or "x509", and gpg.<format>.program
that is used to specify what program to use to deal with the format)
to allow x.509 certs with CMS via "gpgsm" to be used instead of
openpgp via "gnupg".
* Many more strings are prepared for l10n.
* "git p4 submit" learns to ask its own pre-submit hook if it should
continue with submitting.
* The test performed at the receiving end of "git push" to prevent
bad objects from entering repository can be customized via
receive.fsck.* configuration variables; we now have gained a
counterpart to do the same on the "git fetch" side, with
fetch.fsck.* configuration variables.
* "git pull --rebase=interactive" learned "i" as a short-hand for
"interactive".
* "git instaweb" has been adjusted to run better with newer Apache on
RedHat based distros.
* "git range-diff" is a reimplementation of "git tbdiff" that lets us
compare individual patches in two iterations of a topic.
* The sideband code learned to optionally paint selected keywords at
the beginning of incoming lines on the receiving end.
* "git branch --list" learned to take the default sort order from the
'branch.sort' configuration variable, just like "git tag --list"
pays attention to 'tag.sort'.
* "git worktree" command learned "--quiet" option to make it less
verbose.
Performance, Internal Implementation, Development Support etc.
* The bulk of "git submodule foreach" has been rewritten in C.
* The in-core "commit" object had an all-purpose "void *util" field,
which was tricky to use especially in library-ish part of the
code. All of the existing uses of the field has been migrated to a
more dedicated "commit-slab" mechanism and the field is eliminated.
* A less often used command "git show-index" has been modernized.
(merge fb3010c31f jk/show-index later to maint).
* The conversion to pass "the_repository" and then "a_repository"
throughout the object access API continues.
* Continuing with the idea to programatically enumerate various
pieces of data required for command line completion, teach the
codebase to report the list of configuration variables
subcommands care about to help complete them.
* Separate "rebase -p" codepath out of "rebase -i" implementation to
slim down the latter and make it easier to manage.
* Make refspec parsing codepath more robust.
* Some flaky tests have been fixed.
* Continuing with the idea to programmatically enumerate various
pieces of data required for command line completion, the codebase
has been taught to enumerate options prefixed with "--no-" to
negate them.
* Build and test procedure for netrc credential helper (in contrib/)
has been updated.
* Remove unused function definitions and declarations from ewah
bitmap subsystem.
* Code preparation to make "git p4" closer to be usable with Python 3.
* Tighten the API to make it harder to misuse in-tree .gitmodules
file, even though it shares the same syntax with configuration
files, to read random configuration items from it.
* "git fast-import" has been updated to avoid attempting to create
delta against a zero-byte-long string, which is pointless.
* The codebase has been updated to compile cleanly with -pedantic
option.
(merge 2b647a05d7 bb/pedantic later to maint).
* The character display width table has been updated to match the
latest Unicode standard.
(merge 570951eea2 bb/unicode-11-width later to maint).
* test-lint now looks for broken use of "VAR=VAL shell_func" in test
scripts.
* Conversion from uchar[40] to struct object_id continues.
* Recent "security fix" to pay attention to contents of ".gitmodules"
while accepting "git push" was a bit overly strict than necessary,
which has been adjusted.
* "git fsck" learns to make sure the optional commit-graph file is in
a sane state.
* "git diff --color-moved" feature has further been tweaked.
* Code restructuring and a small fix to transport protocol v2 during
fetching.
* Parsing of -L[<N>][,[<M>]] parameters "git blame" and "git log"
take has been tweaked.
* lookup_commit_reference() and friends have been updated to find
in-core object for a specific in-core repository instance.
* Various glitches in the heuristics of merge-recursive strategy have
been documented in new tests.
* "git fetch" learned a new option "--negotiation-tip" to limit the
set of commits it tells the other end as "have", to reduce wasted
bandwidth and cycles, which would be helpful when the receiving
repository has a lot of refs that have little to do with the
history at the remote it is fetching from.
* For a large tree, the index needs to hold many cache entries
allocated on heap. These cache entries are now allocated out of a
dedicated memory pool to amortize malloc(3) overhead.
* Tests to cover various conflicting cases have been added for
merge-recursive.
* Tests to cover conflict cases that involve submodules have been
added for merge-recursive.
* Look for broken "&&" chains that are hidden in subshell, many of
which have been found and corrected.
* The singleton commit-graph in-core instance is made per in-core
repository instance.
* "make DEVELOPER=1 DEVOPTS=pedantic" allows developers to compile
with -pedantic option, which may catch more problematic program
constructs and potential bugs.
* Preparatory code to later add json output for telemetry data has
been added.
* Update the way we use Coccinelle to find out-of-style code that
need to be modernised.
* It is too easy to misuse system API functions such as strcat();
these selected functions are now forbidden in this codebase and
will cause a compilation failure.
* Add a script (in contrib/) to help users of VSCode work better with
our codebase.
* The Travis CI scripts were taught to ship back the test data from
failed tests.
(merge aea8879a6a sg/travis-retrieve-trash-upon-failure later to maint).
* The parse-options machinery learned to refrain from enclosing
placeholder string inside a "<bra" and "ket>" pair automatically
without PARSE_OPT_LITERAL_ARGHELP. Existing help text for option
arguments that are not formatted correctly have been identified and
fixed.
(merge 5f0df44cd7 rs/parse-opt-lithelp later to maint).
* Noiseword "extern" has been removed from function decls in the
header files.
* A few atoms like %(objecttype) and %(objectsize) in the format
specifier of "for-each-ref --format=<format>" can be filled without
getting the full contents of the object, but just with the object
header. These cases have been optimized by calling
oid_object_info() API (instead of reading and inspecting the data).
* The end result of documentation update has been made to be
inspected more easily to help developers.
* The API to iterate over all objects learned to optionally list
objects in the order they appear in packfiles, which helps locality
of access if the caller accesses these objects while as objects are
enumerated.
* Improve built-in facility to catch broken &&-chain in the tests.
* The more library-ish parts of the codebase learned to work on the
in-core index-state instance that is passed in by their callers,
instead of always working on the singleton "the_index" instance.
* A test prerequisite defined by various test scripts with slightly
different semantics has been consolidated into a single copy and
made into a lazily defined one.
(merge 6ec633059a wc/make-funnynames-shared-lazy-prereq later to maint).
* After a partial clone, repeated fetches from promisor remote would
have accumulated many packfiles marked with .promisor bit without
getting them coalesced into fewer packfiles, hurting performance.
"git repack" now learned to repack them.
* Partially revert the support for multiple hash functions to regain
hash comparison performance; we'd think of a way to do this better
in the next cycle.
* "git help --config" (which is used in command line completion)
missed the configuration variables not described in the main
config.txt file but are described in another file that is included
by it, which has been corrected.
* The test linter code has learned that the end of here-doc mark
"EOF" can be quoted in a double-quote pair, not just in a
single-quote pair.
Fixes since v2.9.1
------------------
* A fix merged to v2.9.1 had a few tests that are not meant to be
run on platforms without 64-bit long, which caused unnecessary
test failures on them because we didn't detect the platform and
skip them. These tests are now skipped on platforms that they
are not applicable to.
Fixes since v2.9
----------------
* When "git daemon" is run without --[init-]timeout specified, a
connection from a client that silently goes offline can hang around
for a long time, wasting resources. The socket-level KEEPALIVE has
been enabled to allow the OS to notice such failed connections.
* The commands in `git log` family take %C(auto) in a custom format
string. This unconditionally turned the color on, ignoring
--no-color or with --color=auto when the output is not connected to
a tty; this was corrected to make the format truly behave as
"auto".
* "git rev-list --count" whose walk-length is limited with "-n"
option did not work well with the counting optimized to look at the
bitmap index.
* "git show -W" (extend hunks to cover the entire function, delimited
by lines that match the "funcname" pattern) used to show the entire
file when a change added an entire function at the end of the file,
which has been fixed.
* The documentation set has been updated so that literal commands,
configuration variables and environment variables are consistently
typeset in fixed-width font and bold in manpages.
* "git svn propset" subcommand that was added in 2.3 days is
documented now.
* The documentation tries to consistently spell "GPG"; when
referring to the specific program name, "gpg" is used.
* "git reflog" stopped upon seeing an entry that denotes a branch
creation event (aka "unborn"), which made it appear as if the
reflog was truncated.
* The git-prompt scriptlet (in contrib/) was not friendly with those
who uses "set -u", which has been fixed.
* A codepath that used alloca(3) to place an unbounded amount of data
on the stack has been updated to avoid doing so.
* "git update-index --add --chmod=+x file" may be usable as an escape
hatch, but not a friendly thing to force for people who do need to
use it regularly. "git add --chmod=+x file" can be used instead.
* Build improvements for gnome-keyring (in contrib/)
* "git status" used to say "working directory" when it meant "working
tree".
* Comments about misbehaving FreeBSD shells have been clarified with
the version number (9.x and before are broken, newer ones are OK).
* "git cherry-pick A" worked on an unborn branch, but "git
cherry-pick A..B" didn't.
* "git add -i/-p" learned to honor diff.compactionHeuristic
experimental knob, so that the user can work on the same hunk split
as "git diff" output.
* "log --graph --format=" learned that "%>|(N)" specifies the width
relative to the terminal's left edge, not relative to the area to
draw text that is to the right of the ancestry-graph section. It
also now accepts negative N that means the column limit is relative
to the right border.
* The ownership rule for the piece of memory that hold references to
be fetched in "git fetch" was screwy, which has been cleaned up.
* "git bisect" makes an internal call to "git diff-tree" when
bisection finds the culprit, but this call did not initialize the
data structure to pass to the diff-tree API correctly.
* Formats of the various data (and how to validate them) where we use
GPG signature have been documented.
* Fix an unintended regression in v2.9 that breaks "clone --depth"
that recurses down to submodules by forcing the submodules to also
be cloned shallowly, which many server instances that host upstream
of the submodules are not prepared for.
* Fix unnecessarily waste in the idiomatic use of ': ${VAR=default}'
to set the default value, without enclosing it in double quotes.
* Some platform-specific code had non-ANSI strict declarations of C
functions that do not take any parameters, which has been
corrected.
* The internal code used to show local timezone offset is not
prepared to handle timestamps beyond year 2100, and gave a
bogus offset value to the caller. Use a more benign looking
+0000 instead and let "git log" going in such a case, instead
of aborting.
* One among four invocations of readlink(1) in our test suite has
been rewritten so that the test can run on systems without the
command (others are in valgrind test framework and t9802).
* t/perf needs /usr/bin/time with GNU extension; the invocation of it
is updated to "gtime" on Darwin.
* A bug, which caused "git p4" while running under verbose mode to
report paths that are omitted due to branch prefix incorrectly, has
been fixed; the command said "Ignoring file outside of prefix" for
paths that are _inside_.
* The top level documentation "git help git" still pointed at the
documentation set hosted at now-defunct google-code repository.
Update it to point to https://git.github.io/htmldocs/git.html
instead.
Also contains minor documentation updates and code clean-ups.
* The experimental untracked-cache feature were buggy when paths with
a few levels of subdirectories are involved.
* Recent versions of scripted "git am" has a performance regression
in "git am --skip" codepath, which no longer exists in the
built-in version on the 'master' front. Fix the regression in
the last scripted version that appear in 2.5.x maintenance track
and older.
Also contains typofixes, documentation updates and trivial code
clean-ups.
UI, Workflows & Features
* The bash completion script (in contrib/) learned a few options that
"git revert" takes.
* Whitespace breakages in deleted and context lines can also be
painted in the output of "git diff" and friends with the new
--ws-error-highlight option.
* List of commands shown by "git help" are grouped along the workflow
elements to help early learners.
* "git p4" now detects the filetype (e.g. binary) correctly even when
the files are opened exclusively.
* git p4 attempts to better handle branches in Perforce.
* "git p4" learned "--changes-block-size <n>" to read the changes in
chunks from Perforce, instead of making one call to "p4 changes"
that may trigger "too many rows scanned" error from Perforce.
* More workaround for Perforce's row number limit in "git p4".
* Unlike "$EDITOR" and "$GIT_EDITOR" that can hold the path to the
command and initial options (e.g. "/path/to/emacs -nw"), 'git p4'
did not let the shell interpolate the contents of the environment
variable that name the editor "$P4EDITOR" (and "$EDITOR", too).
This release makes it in line with the rest of Git, as well as with
Perforce.
* A new short-hand <branch>@{push} denotes the remote-tracking branch
that tracks the branch at the remote the <branch> would be pushed
to.
* "git show-branch --topics HEAD" (with no other arguments) did not
do anything interesting. Instead, contrast the given revision
against all the local branches by default.
* A replacement for contrib/workdir/git-new-workdir that does not
rely on symbolic links and make sharing of objects and refs safer
by making the borrowee and borrowers aware of each other.
Consider this as still an experimental feature; its UI is still
likely to change.
* Tweak the sample "store" backend of the credential helper to honor
XDG configuration file locations when specified.
* A heuristic we use to catch mistyped paths on the command line
"git <cmd> <revs> <pathspec>" is to make sure that all the non-rev
parameters in the later part of the command line are names of the
files in the working tree, but that means "git grep $str -- \*.c"
must always be disambiguated with "--", because nobody sane will
create a file whose name literally is asterisk-dot-see. Loosen the
heuristic to declare that with a wildcard string the user likely
meant to give us a pathspec.
* "git merge FETCH_HEAD" learned that the previous "git fetch" could
be to create an Octopus merge, i.e. recording multiple branches
that are not marked as "not-for-merge"; this allows us to lose an
old style invocation "git merge <msg> HEAD $commits..." in the
implementation of "git pull" script; the old style syntax can now
be deprecated (but not removed yet).
* Filter scripts were run with SIGPIPE disabled on the Git side,
expecting that they may not read what Git feeds them to filter.
We however treated a filter that does not read its input fully
before exiting as an error. We no longer do and ignore EPIPE
when writing to feed the filter scripts.
This changes semantics, but arguably in a good way. If a filter
can produce its output without fully consuming its input using
whatever magic, we now let it do so, instead of diagnosing it
as a programming error.
* Instead of dying immediately upon failing to obtain a lock, the
locking (of refs etc) retries after a short while with backoff.
* Introduce http.<url>.SSLCipherList configuration variable to tweak
the list of cipher suite to be used with libcURL when talking with
https:// sites.
* "git subtree" script (in contrib/) used "echo -n" to produce
progress messages in a non-portable way.
* "git subtree" script (in contrib/) does not have --squash option
when pushing, but the documentation and help text pretended as if
it did.
* The Git subcommand completion (in contrib/) no longer lists credential
helpers among candidates; they are not something the end user would
invoke interactively.
* The index file can be taught with "update-index --untracked-cache"
to optionally remember already seen untracked files, in order to
speed up "git status" in a working tree with tons of cruft.
* "git mergetool" learned to drive WinMerge as a backend.
* "git upload-pack" that serves "git fetch" can be told to serve
commits that are not at the tip of any ref, as long as they are
reachable from a ref, with uploadpack.allowReachableSHA1InWant
configuration variable.
{perl>=5.16.6,p5-ExtUtils-ParseXS>=3.15}:../../devel/p5-ExtUtils-ParseXS
since pkgsrc enforces the newest perl version anyway, so they
should always pick perl, but sometimes (pkg_add) don't due to the
design of the {,} syntax.
No effective change for the above reason.

Changelog:
Git v2.4.5 Release Notes
========================
Fixes since v2.4.4
------------------
* The setup code used to die when core.bare and core.worktree are set
inconsistently, even for commands that do not need working tree.
* There was a dead code that used to handle "git pull --tags" and
show special-cased error message, which was made irrelevant when
the semantics of the option changed back in Git 1.9 days.
* "color.diff.plain" was a misnomer; give it 'color.diff.context' as
a more logical synonym.
* The configuration reader/writer uses mmap(2) interface to access
the files; when we find a directory, it barfed with "Out of memory?".
* Recent "git prune" traverses young unreachable objects to safekeep
old objects in the reachability chain from them, which sometimes
showed unnecessary error messages that are alarming.
* "git rebase -i" fired post-rewrite hook when it shouldn't (namely,
when it was told to stop sequencing with 'exec' insn).
Also contains typofixes, documentation updates and trivial code
clean-ups.
Git v2.4.4 Release Notes
========================
Fixes since v2.4.3
------------------
* l10n updates for German.
* An earlier leakfix to bitmap testing code was incomplete.
* "git clean pathspec..." tried to lstat(2) and complain even for
paths outside the given pathspec.
* Communication between the HTTP server and http_backend process can
lead to a dead-lock when relaying a large ref negotiation request.
Diagnose the situation better, and mitigate it by reading such a
request first into core (to a reasonable limit).
* The clean/smudge interface did not work well when filtering an
empty contents (failed and then passed the empty input through).
It can be argued that a filter that produces anything but empty for
an empty input is nonsense, but if the user wants to do strange
things, then why not?
* Make "git stash something --help" error out, so that users can
safely say "git stash drop --help".
* Clarify that "log --raw" and "log --format=raw" are unrelated
concepts.
* Catch a programmer mistake to feed a pointer not an array to
ARRAY_SIZE() macro, by using a couple of GCC extensions.
Also contains typofixes, documentation updates and trivial code
clean-ups.
------------------
* Commands that take pathspecs on the command line misbehaved when
the pathspec is given as an absolute pathname (which is a
practice not particularly encouraged) that points at a symbolic
link in the working tree.
* An earlier fix to the shell prompt script (in contrib/) for using
the PROMPT_COMMAND interface did not correctly check if the extra
code path needs to trigger, causing the branch name not to appear
when 'promptvars' option is disabled in bash or PROMPT_SUBST is
unset in zsh.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
* "git p4" dealing with changes in binary files were broken by a
change in 1.9 release.
* The shell prompt script (in contrib/), when using the PROMPT_COMMAND
interface, used an unsafe construct when showing the branch name in
$PS1.
* "git rebase" used a POSIX shell construct FreeBSD /bin/sh does not
work well with.
* Some more Unicode codepoints defined in Unicode 6.3 as having
zero width have been taught to our display column counting logic.
* Some tests used shell constructs that did not work well on
FreeBSD.
* "git diff -- ':(icase)makefile'" was unnecessarily rejected at the
command line parser.
* "git cat-file --batch-check=ok" did not check the existence of
the named object.
* "git am --abort" sometimes complained about not being able to write
a tree with an 0{40} object in it.
* Two processes creating loose objects at the same time could have
failed unnecessarily when the name of their new objects started
with the same byte value, due to a race condition.
Also contains typofixes, documentation updates and trivial code clean-ups
* Some old versions of bash do not grok some constructs like
'printf -v varname' which the prompt and completion code started
to use recently. The completion and prompt scripts have been
adjusted to work better with these old versions of bash.
* In FreeBSD's and NetBSD's "sh", a return in a dot script in a
function returns from the function, not only in the dot script,
breaking "git rebase" on these platforms (regression introduced
in 1.8.4-rc1).
* "git rebase -i" and other scripted commands were feeding a
random, data dependant error message to 'echo' and expecting it
to come out literally.
* Setting the "submodule.<name>.path" variable to the empty
"true" caused the configuration parser to segfault.
* Output from "git log --full-diff -- <pathspec>" looked strange
because comparison was done with the previous ancestor that
touched the specified <pathspec>, causing the patches for paths
outside the pathspec to show more than the single commit has
changed.
* The auto-tag-following code in "git fetch" tries to reuse the
same transport twice when the serving end does not cooperate and
does not give tags that point to commits that are asked for as
part of the primary transfer. Unfortunately, Git-aware transport
helper interface is not designed to be used more than once, hence
this did not work over smart-http transfer. Fixed.
* Send a large request to read(2)/write(2) as a smaller but still
reasonably large chunks, which would improve the latency when the
operation needs to be killed and incidentally works around broken
64-bit systems that cannot take a 2GB write or read in one go.
* A ".mailmap" file that ends with an incomplete line, when read
from a blob, was not handled properly.
* The recent "short-cut clone connectivity check" topic broke a
shallow repository when a fetch operation tries to auto-follow
tags.
* When send-email comes up with an error message to die with upon
failure to start an SSL session, it tried to read the error
string from a wrong place.
* A call to xread() was used without a loop to cope with short
read in the codepath to stream large blobs to a pack.
* On platforms with fgetc() and friends defined as macros, the
configuration parser did not compile.
* New versions of MediaWiki introduced a new API for returning
more than 500 results in response to a query, which would cause
the MediaWiki remote helper to go into an infinite loop.
* Subversion's serf access method (the only one available in
Subversion 1.8) for http and https URLs in skelta mode tells its
caller to open multiple files at a time, which made "git svn
fetch" complain that "Temp file with moniker 'svn_delta' already
in use" instead of fetching.
Also contains a handful of trivial code clean-ups, documentation
updates, updates to the test suite, etc.
* When $HOME is misconfigured to point at an unreadable directory, we
used to complain and die. The check has been loosened.
* Handling of negative exclude pattern for directories "!dir" was
broken in the update to v1.8.3.
Also contains a handful of trivial code clean-ups, documentation
updates, updates to the test suite, etc.
I'm not particularly paying attention to gitweb. (This package
doesn't need a lot of attention, as it's automatically updated with
git, and stable upstream.)
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
---------------------
* When "git am" is fed an input that has multiple "Content-type: ..."
header, it did not grok charset= attribute correctly.
* Even during a conflicted merge, "git blame $path" always meant to
blame uncommitted changes to the "working tree" version; make it
more useful by showing cleanly merged parts as coming from the other
branch that is being merged.
* "git blame MAKEFILE" run in a history that has "Makefile" but not
"MAKEFILE" should say "No such file MAKEFILE in HEAD", but got
confused on a case insensitive filesystem and failed to do so.
* "git fetch --all", when passed "--no-tags", did not honor the
"--no-tags" option while fetching from individual remotes (the same
issue existed with "--tags", but combination "--all --tags" makes
much less sense than "--all --no-tags").
* "git log/diff/format-patch --stat" showed the "N line(s) added"
comment in user's locale and caused careless submitters to send
patches with such a line in them to projects whose project language
is not their language, mildly irritating others. Localization to
the line has been disabled for now.
* "git log --all-match --grep=A --grep=B" ought to show commits that
mention both A and B, but when these three options are used with
--author or --committer, it showed commits that mention either A or
B (or both) instead.
* The subcommand to remove the definition of a remote in "git remote"
was named "rm" even though all other subcommands were spelled out.
Introduce "git remote remove" to remove confusion, and keep "rm" as
a backward compatible synonym.
Also contains a handful of documentation updates.
* "git p4" (in contrib/) submit the changes to a wrong place when the
"--use-client-spec" option is set.
* The config.mak.autogen generated by optional autoconf support tried
to link the binary with -lintl even when libintl.h is missing from
the system.
* When the filter driver exits before reading the content before the
main git process writes the contents to be filtered to the pipe to
it, the latter could be killed with SIGPIPE instead of ignoring
such an event as an error.
* "git add --refresh <pathspec>" used to warn about unmerged paths
outside the given pathspec.
* The bulk check-in codepath in "git add" streamed contents that
needs smudge/clean filters without running them, instead of punting
and delegating to the codepath to run filters after slurping
everything to core.
* "git branch --with $that" assumed incorrectly that the user will never
ask the question with nonsense value in $that.
* "git bundle create" produced a corrupt bundle file upon seeing
commits with excessively long subject line.
* When a remote helper exits before reading the blank line from the
main git process to signal the end of commands, the latter could be
killed with SIGPIPE. Instead we should ignore such event as a
non-error.
* The commit log template given with "git merge --edit" did not have
a short instructive text like what "git commit" gives.
* "git rev-list --verify-objects -q" omitted the extra verification
it needs to do over "git rev-list --objects -q" by mistake.
* "gitweb" used to drop warnings in the log file when "heads" view is
accessed in a repository whose HEAD does not point at a valid
branch.
* An invalid regular expression pattern given by an end user made
"gitweb" to return garbled response.

gitweb: Introduce esc_attr to escape attributes of HTML elements
It is needed only to escape attributes of handcrafted HTML elements,
and not those generated using CGI.pm subroutines / methods for HTML
generation.
While at it, add esc_url and esc_html where needed, and prefer to use
CGI.pm HTML generating methods than handcrafted HTML code. Most of
those are probably unnecessary (could be exploited only by person with
write access to gitweb config, or at least access to the repository).
This fixes CVE-2010-3906

gitweb provides an easy to use and full-fledged web interface to
your Git repositories. It allows users to browse the contents of
all served projects, including the ability to inspect individual
files and their history for any of the available branches.
