v1.0
----
This is release v1.0 "Luftschloss", which is the first stabe release of
libgit2. The API will stay compatible across all releases of the same major
version. This release includes bugfixes only and supersedes v0.99, which will
stop being maintained. Both v0.27 and v0.28 stay supported in accordance with
our release policy.
### Changes or improvements
- CMake was converted to make use of the GNUInstallDirs module for both our
pkgconfig and install targets in favor of our custom build options
`BIN_INSTALL_DIR`, `LIB_INSTALL_DIR` and `INCLUDE_INSTALL_DIR`. Instead, you
can now use CMakes standard variables `CMAKE_INSTALL_BINDIR`,
`CMAKE_INSTALL_LIBDIR` and `CMAKE_INSTALL_INCLUDEDIR`.
- Some CMake build options accepted either a specific value or a boolean value
to disable the option altogether or use automatic detection. We only accepted
"ON" or "OFF", but none of the other values CMake recognizes as boolean. This
was aligned with CMake's understanding of booleans.
- The installed pkgconfig file contained incorrect values for both `libdir` and
`includedir` variables.
- If using pcre2 for regular expressions, then we incorrectly added "pcre2"
instead of "pcre2-8" to our pkgconfig dependencies, which was corrected.
- Fixed building the bundled ntlmclient dependency on FreeBSD, OpenBSD and
SunOS.
- When writing symlinks on Windows, we incorrectly handled relative symlink
targets, which was corrected.
- When using the HTTP protocol via macOS' SecureTransport implementation, reads
could stall at the end of the session and only continue after a timeout of 60
seconds was reached.
- The filesystem-based reference callback didn't corectly initialize the backend
version.
- A segmentation fault was fixed when calling `git_blame_buffer()` for files
that were modified and added to the index.
- A backwards-incompatible change was introduced when we moved some structures
from "git2/credentials.h" into "git2/sys/credentials.h". This was fixed in the
case where you do not use hard deprecation.
- Improved error handling in various places.
This release contains plenty of new features, bug-fixes, and general
improvements. Some of the most important highlights include:
* We did it again, the MATE desktop environment is easier to use than before,
once the user starts the session. Do you want to hide applications startup?
Now you can set which applications to show on startup.
* Engrampa now has support for a handful of extra formats, as well as fixed
support for passwords and unicode characters in some of them.
* Eye of MATE now has support for Wayland and we’ve added support for
embedded color profiles.
* The thumbnail generation has been reworked and fixed in several places.
* Added support for webp files.
* Our window manager, marco, has gotten quite a few changes:
* We’ve brought a bunch of window decorations from the past to feed
your nostalgia.
* Finally added invisible resize borders. No more struggling to find a
border to grab with your mouse!
* All window controls (you know, the min, max, close buttons) are now
rendered in HiDPI.
* The Alt+Tab and Workspace Switcher popups have been entirely reworked.
Now they render in beautiful OSD style, are more configurable, and can
respond to keyboard arrows.
* Tiling windows with the keyboard now allows you to cycle through
different window sizes. You no longer need to feel constrained by only
half of your screen.
* The System Monitor panel applet now has support for NVMe drives.
* Calculator now supports using either “pi” or “π”.
* Scientific notation has been improved.
* Some fixes for supporting pre-defined physical constants.
* The Control Center now displays its icons correctly on HiDPI displays.
* A brand new Time And Date Manager app has been added.
* The Mouse app now supports acceleration profiles.
* The Preferred Applications app has been improved for accessibility, as well
as better support for integration with IM clients.
* The Indicator Applet has slightly better interaction with
oddly-sized icons.
* Speaking of icons, the network manager applet icons in our own themes have
been entirely redesigned and can now be enjoyed on HiDPI displays.
* If you’re the type of person that does not like to be disturbed when busy,
or giving a presentation, or watching a movie, you’ll be happy to know that
the notification daemon now supports a Do-Not-Disturb mode.
* The MATE Panel had several bugs that caused crashes in the past when
changing layouts. Those are now fixed!
* Support for Wayland compatibility has improved considerably.
* Status icons (a.k.a. notification area, or system tray) have support
for HiDPI displays.
* Wanda the Fish got a make-over and now you can enjoy her in full
HiDPI glory.
* The window list applet now supports window thumbnails on hover.
* Various accessibility improvements throughout the panel and its
core applets.
* If your system doesn’t, uh, support systemd you might be interested in
knowing that we’ve added support for elogind to both the MATE Screensaver
and the MATE Session.
* We’ve also added a brand new MATE Disk Image Mounter utility.
* Mozo, the menu editor, now supports Undo and Redo actions.
* Pluma plugins have now fully switched to Python 3.
* Pluma no longer has to envy anything from other complex editors, since it
can now show the formatting marks.
* i18n: All applications have been migrated from intltools to gettext.
This is a complete replacement and rearchitecture of the Android
project's ADB and fastboot, using libusb1 for USB communications.
This code is mainly targeted to users that need to communicate with
Android devices in an automated fashion, such as in automated
testing. It does not have a daemon between the client and the
device, and therefore does not support multiple simultaneous commands
to the same device.
This reduces the amount the command line utilities complain and makes
this marginally less broken. But, it's a hack around the underlying issue,
it shouldn't treat this as a failure if the underlying libusb driver doesn't
support it.
2019-08-28: v1.0.23
* Add German translation (#446)
* Add Hungarian translation (#493)
* Android: Improved support for Android
* BSD: Remove infinite recursion in OpenBSD backend
* configure.ac: Fix detection of clock_gettime library (#439)
* Core: abandon synchronous transfers when device closure is detected.
* Core: fix error in handling the removal of file descriptors while handling
events.
* Darwin(macOS): Switch from using ResetDevice to USBDeviceReEnumerate (#455)
* Darwin(macOS): Remove code that changed the device class used (#428)
* Darwin(macOS): Reduce hotplug timeout to 1ms (from 5s)
* New API libusb_set_log_cb() to redirect global and per context log
messages to the provided log handling function
* New API libusb_wrap_sys_device to allow the user to specify the
usb device to use.
* Solaris: Break infinite recursion in backend clock_gettime
* Solaris: Enable timerfd on sunos when available
* Windows: Add support for isochronous transfers with WinUSB
* Various other bug fixes and improvements
v0.9.0
When the file name extension of a file to be opened for reading is not available, the content is inspected (if possible) and used to determine which compression format applies.
This release drops Python 2.7 and 3.4 support. Python 3.5 or later is now required.
0.29.16:
Bugs fixed
* Temporary internal variables in nested prange loops could leak into other
threads.
* Default arguments on fused functions could crash.
* C-tuples declared in ``.pxd`` files could generate incomplete C code.
* Fused functions were not always detected and optimised as Cython
implemented functions.
* Valid Python object concatenation of (iterable) strings to non-strings
could fail with an exception.
* Using C functions as temporary values lead to invalid C code.
* Fix an unhandled C++ exception in comparisons.
* Fix deprecated import of "imp" module.
* Fix compatibility with Pythran 0.9.6 and later.
* The ``_Py_PyAtExit()`` function in ``cpython.pylifecycle`` was misdeclared.
* Several missing declarations in ``cpython.*`` were added.
* A declaration for ``libc.math.fpclassify()`` was added.
* Avoid "undeclared" warning about automatically generated pickle methods.
* Avoid C compiler warning about unreachable code in ``prange()``.
* Some C compiler warnings in PyPy were resolved.
The CHANGES.md file hasn't been updated in a while, but there do not seem
to have been major changes; nevertheless, this version corrects a build
failure.
Fix common misspellings in text files. It's designed primarily for
checking misspelled words in source code, but it can be used with
other files as well.
Git 2.26 Release Notes
======================
Updates since v2.25
-------------------
Backward compatibility notes
* "git rebase" uses a different backend that is based on the 'merge'
machinery by default. There are a few known differences in the
behaviour from the traditional machinery based on patch+apply.
If your workflow is negatively affected by this change, please
report it to git@vger.kernel.org so that we can take a look into
it. After doing so, you can set the 'rebase.backend' configuration
variable to 'apply', in order to use the old default behaviour in
the meantime.
UI, Workflows & Features
* Sample credential helper for using .netrc has been updated to work
out of the box.
* gpg.minTrustLevel configuration variable has been introduced to
tell various signature verification codepaths the required minimum
trust level.
* The command line completion (in contrib/) learned to complete
subcommands and arguments to "git worktree".
* Disambiguation logic to tell revisions and pathspec apart has been
tweaked so that backslash-escaped glob special characters do not
count in the "wildcards are pathspec" rule.
* One effect of specifying where the GIT_DIR is (either with the
environment variable, or with the "git --git-dir=<where> cmd"
option) is to disable the repository discovery. This has been
placed a bit more stress in the documentation, as new users often
get confused.
* Two help messages given when "git add" notices the user gave it
nothing to add have been updated to use advise() API.
* A new version of fsmonitor-watchman hook has been introduced, to
avoid races.
* "git config" learned to show in which "scope", in addition to in
which file, each config setting comes from.
* The basic 7 colors learned the brighter counterparts
(e.g. "brightred").
* "git sparse-checkout" learned a new "add" subcommand.
* A configuration element used for credential subsystem can now use
wildcard pattern to specify for which set of URLs the entry
applies.
* "git clone --recurse-submodules --single-branch" now uses the same
single-branch option when cloning the submodules.
* "git rm" and "git stash" learns the new "--pathspec-from-file"
option.
* "git am --show-current-patch" is a way to show the piece of e-mail
for the stopped step, which is not suitable to directly feed "git
apply" (it is designed to be a good "git am" input). It learned a
new option to show only the patch part.
* Handling of conflicting renames in merge-recursive have further
been made consistent with how existing codepaths try to mimic what
is done to add/add conflicts.
Performance, Internal Implementation, Development Support etc.
* Tell .editorconfig that in this project, *.txt files are indented
with tabs.
* The test-lint machinery knew to check "VAR=VAL shell_function"
construct, but did not check "VAR= shell_function", which has been
corrected.
* Replace "git config --bool" calls with "git config --type=bool" in
sample templates.
* The effort to move "git-add--interactive" to C continues.
* Improve error message generation for "git submodule add".
* Preparation of test scripts for the day when the object names will
use SHA-256 continues.
* Warn programmers about pretend_object_file() that allows the code
to tentatively use in-core objects.
* The way "git pack-objects" reuses objects stored in existing pack
to generate its result has been improved.
* The transport protocol version 2 becomes the default one.
* Traditionally, we avoided threaded grep while searching in objects
(as opposed to files in the working tree) as accesses to the object
layer is not thread-safe. This limitation is getting lifted.
* "git rebase -i" (and friends) used to unnecessarily check out the
tip of the branch to be rebased, which has been corrected.
* A low-level API function get_oid(), that accepts various ways to
name an object, used to issue end-user facing error messages
without l10n, which has been updated to be translatable.
* Unneeded connectivity check is now disabled in a partial clone when
fetching into it.
* Some rough edges in the sparse-checkout feature, especially around
the cone mode, have been cleaned up.
* The diff-* plumbing family of subcommands now pay attention to the
diff.wsErrorHighlight configuration, which has been ignored before;
this allows "git add -p" to also show the whitespace problems to
the end user.
* Some codepaths were given a repository instance as a parameter to
work in the repository, but passed the_repository instance to its
callees, which has been cleaned up (somewhat).
* Memory footprint and performance of "git name-rev" has been
improved.
* The object reachability bitmap machinery and the partial cloning
machinery were not prepared to work well together, because some
object-filtering criteria that partial clones use inherently rely
on object traversal, but the bitmap machinery is an optimization
to bypass that object traversal. There however are some cases
where they can work together, and they were taught about them.
* "git rebase" has learned to use the merge backend (i.e. the
machinery that drives "rebase -i") by default, while allowing
"--apply" option to use the "apply" backend (e.g. the moral
equivalent of "format-patch piped to am"). The rebase.backend
configuration variable can be set to customize.
* Underlying machinery of "git bisect--helper" is being refactored
into pieces that are more easily reused.
Fixes since v2.25
-----------------
* "git commit" gives output similar to "git status" when there is
nothing to commit, but without honoring the advise.statusHints
configuration variable, which has been corrected.
* has_object_file() said "no" given an object registered to the
system via pretend_object_file(), making it inconsistent with
read_object_file(), causing lazy fetch to attempt fetching an
empty tree from promisor remotes.
* Complete an update to tutorial that encourages "git switch" over
"git checkout" that was done only half-way.
* C pedantry ;-) fix.
* The code that tries to skip over the entries for the paths in a
single directory using the cache-tree was not careful enough
against corrupt index file.
* Reduce unnecessary round-trip when running "ls-remote" over the
stateless RPC mechanism.
* "git restore --staged" did not correctly update the cache-tree
structure, resulting in bogus trees to be written afterwards, which
has been corrected.
* The code recently added to move to the entry beyond the ones in the
same directory in the index in the sparse-cone mode did not count
the number of entries to skip over incorrectly, which has been
corrected.
* Rendering by "git log --graph" of ancestry lines leading to a merge
commit were made suboptimal to waste vertical space a bit with a
recent update, which has been corrected.
* Work around test breakages caused by custom regex engine used in
libasan, when address sanitizer is used with more recent versions
of gcc and clang.
* Minor bugfixes to "git add -i" that has recently been rewritten in C.
* "git fetch --refmap=" option has got a better documentation.
* "git checkout X" did not correctly fail when X is not a local
branch but could name more than one remote-tracking branches
(i.e. to be dwimmed as the starting point to create a corresponding
local branch), which has been corrected.
(merge fa74180d08 am/checkout-file-and-ref-ref-ambiguity later to maint).
* Corner case bugs in "git clean" that stems from a (necessarily for
performance reasons) awkward calling convention in the directory
enumeration API has been corrected.
* A fetch that is told to recursively fetch updates in submodules
inevitably produces reams of output, and it becomes hard to spot
error messages. The command has been taught to enumerate
submodules that had errors at the end of the operation.
(merge 0222540827 es/fetch-show-failed-submodules-atend later to maint).
* The "--recurse-submodules" option of various subcommands did not
work well when run in an alternate worktree, which has been
corrected.
* Futureproofing a test not to depend on the current implementation
detail.
* Running "git rm" on a submodule failed unnecessarily when
.gitmodules is only cache-dirty, which has been corrected.
* C pedantry ;-) fix.
* "git grep --no-index" should not get affected by the contents of
the .gitmodules file but when "--recurse-submodules" is given or
the "submodule.recurse" variable is set, it did. Now these
settings are ignored in the "--no-index" mode.
* Technical details of the bundle format has been documented.
* Unhelpful warning messages during documentation build have been squelched.
* "git rebase -i" identifies existing commits in its todo file with
their abbreviated object name, which could become ambiguous as it
goes to create new commits, and has a mechanism to avoid ambiguity
in the main part of its execution. A few other cases however were
not covered by the protection against ambiguity, which has been
corrected.
* Allow the rebase.missingCommitsCheck configuration to kick in when
"rebase --edit-todo" and "rebase --continue" restarts the procedure.
(merge 5a5445d878 ag/edit-todo-drop-check later to maint).
* The way "git submodule status" reports an initialized but not yet
populated submodule has not been reimplemented correctly when a
part of the "git submodule" command was rewritten in C, which has
been corrected.
(merge f38c92452d pk/status-of-uncloned-submodule later to maint).
* The code to automatically shrink the fan-out in the notes tree had
an off-by-one bug, which has been killed.
* The index-pack code now diagnoses a bad input packstream that
records the same object twice when it is used as delta base; the
code used to declare a software bug when encountering such an
input, but it is an input error.
* The code to compute the commit-graph has been taught to use a more
robust way to tell if two object directories refer to the same
thing.
(merge a7df60cac8 tb/commit-graph-object-dir later to maint).
* "git remote rename X Y" needs to adjust configuration variables
(e.g. branch.<name>.remote) whose value used to be X to Y.
branch.<name>.pushRemote is now also updated.
* Update to doc-diff.
* Doc markup fix.
* "git check-ignore" did not work when the given path is explicitly
marked as not ignored with a negative entry in the .gitignore file.
* The merge-recursive machinery failed to refresh the cache entry for
a merge result in a couple of places, resulting in an unnecessary
merge failure, which has been fixed.
* Fix for a bug revealed by a recent change to make the protocol v2
the default.
* In rare cases "git worktree add <path>" could think that <path>
was already a registered worktree even when it wasn't and refuse
to add the new worktree. This has been corrected.
(merge bb69b3b009 es/worktree-avoid-duplication-fix later to maint).
* "git push" should stop from updating a branch that is checked out
when receive.denyCurrentBranch configuration is set, but it failed
to pay attention to checkouts in secondary worktrees. This has
been corrected.
(merge 4d864895a2 hv/receive-denycurrent-everywhere later to maint).
* "git rebase BASE BRANCH" rebased/updated the tip of BRANCH and
checked it out, even when the BRANCH is checked out in a different
worktree. This has been corrected.
(merge b5cabb4a96 es/do-not-let-rebase-switch-to-protected-branch later to maint).
* "git describe" in a repository with multiple root commits sometimes
gave up looking for the best tag to describe a given commit with
too early, which has been adjusted.
* "git merge signed-tag" while lacking the public key started to say
"No signature", which was utterly wrong. This regression has been
reverted.
* MinGW's poll() emulation has been improved.
* "git show" and others gave an object name in raw format in its
error output, which has been corrected to give it in hex.
* "git fetch" over HTTP walker protocol did not show any progress
output. We inherently do not know how much work remains, but still
we can show something not to bore users.
(merge 7655b4119d rs/show-progress-in-dumb-http-fetch later to maint).
* Both "git ls-remote -h" and "git grep -h" give short usage help,
like any other Git subcommand, but it is not unreasonable to expect
that the former would behave the same as "git ls-remote --head"
(there is no other sensible behaviour for the latter). The
documentation has been updated in an attempt to clarify this.

New in 1.16.2:
* New features added
- add zstd support and the automake option, dist-zstd.
* Miscellaneous changes
- automake no longer requires a @setfilename in each .texi file
* Bugs fixed
- When cleaning the compiled python files, '\n' is not used anymore in the
substitution text of 'sed' transformations. This is done to preserve
compatibility with the 'sed' implementation provided by macOS which
considers '\n' as the 'n' character instead of a newline.
(automake bug#31222)
- For make tags, lisp_LISP is followed by the necessary space when
used with CONFIG_HEADERS.
(automake bug#38139)
- The automake test txinfo-vtexi4.sh no longer fails when localtime
and UTC cross a day boundary.
- Emacsen older than version 25, which require use of
byte-compile-dest-file, are supported again.
ccache 3.7.9
Bug fixes
Fixed replacing of /dev/null when building as root with hard link mode enabled and using -o /dev/null.
Removed incorrect assertion resulting in “ccache: error: Internal error in format” when using -fdebug-prefix-map=X= with X equal to $PWD.
Other
Improved CUDA/NVCC support: Recognize -dc and -x cu options.
Improved name of temporary file used in NFS-safe unlink.
Range library for C++14/17/20. This code was the basis of a formal proposal
to add range support to the C++ standard library. That proposal evolved
through a Technical Specification, and finally into P0896R4 "The One Ranges
Proposal" which was merged into the C++20 working drafts in November 2018.
Ranges are an extension of the Standard Template Library that makes its
iterators and algorithms more powerful by making them composable. Unlike
other range-like solutions which seek to do away with iterators, in range-v3
ranges are an abstration layer on top of iterators.
Single header implementation of std::expected with functional-style extensions.
std::expected is proposed as the preferred way to represent object which
will either have an expected value, or an unexpected value giving information
about why something failed. Unfortunately, chaining together many computations
which may fail can be verbose, as error-checking code will be mixed in with
the actual programming logic. This implementation provides a number of
utilities to make coding with expected cleaner.
