Git ???? Release Notes
======================
Updates since v2.3
------------------
Ports
* Our default I/O size (8 MiB) for large files was too large for some
platforms with smaller SSIZE_MAX, leading to read(2)/write(2)
failures.
* We did not check the curl library version before using
CURLOPT_PROXYAUTH feature that may not exist.
UI, Workflows & Features
* The command usage info strings given by "git cmd -h" and in
documentation have been tweaked for consistency.
* The "sync" subcommand of "git p4" now allows users to exclude
subdirectories like its "clone" subcommand does.
* "git log --invert-grep --grep=WIP" will show only commits that do
not have the string "WIP" in their messages.
* "git push" has been taught a "--atomic" option that makes push to
update more than one ref an "all-or-none" affair.
* Extending the "push to deploy" added in 2.3, the behaviour of "git
push" when updating the branch that is checked out can now be
tweaked by push-to-checkout hook.
* Using environment variable LANGUAGE and friends on the client side,
HTTP-based transports now send Accept-Language when making requests.
* "git send-email" used to accept a mistaken "y" (or "yes") as an
answer to "What encoding do you want to use [UTF-8]? " without
questioning. Now it asks for confirmation when the answer looks
too short to be a valid encoding name.
Performance, Internal Implementation, Development Support etc.
* Implementation of N_() macro has been updated slightly to help us
detect mistakes.
* Implementation of "reflog expire" has been restructured to fit the
reflogs better with the recently updated ref API.
* The transport-helper did not give transport options such as
verbosity, progress, cloning, etc. to import and export based
helpers, like it did for fetch and push based helpers, robbing them
the chance to honor the wish of the end-users better.
* The tests that wanted to see that file becomes unreadable after
running "chmod a-r file", and the tests that wanted to make sure it
is not run as root, we used "can we write into the / directory?" as
a cheap substitute, but on some platforms that is not a good
heuristics. The tests and their prerequisites have been updated to
check what they really require.
(merge f400e51 jk/sanity later to maint).
* The strbuf API was explained between the API documentation and in
the header file. Move missing bits to strbuf.h so that programmers
can check only one place for all necessary information.
* The error handling functions and conventions are now documented in
the API manual.
* Optimize attribute look-up, mostly useful in "git grep" on a
project that does not use many attributes, by avoiding it when we
(should) know that the attributes are not defined in the first
place.
* Typofix in comments.
(merge ef2956a ak/git-pm-typofix later to maint).
* Code clean-up.
(merge 0b868f0 sb/hex-object-name-is-at-most-41-bytes-long later to maint).
(merge 5d30851 dp/remove-duplicated-header-inclusion later to maint).
Also contains various documentation updates and code clean-ups.
Fixes since v2.3
----------------
Unless otherwise noted, all the fixes since v2.3 in the maintenance
track are contained in this release (see the maintenance releases'
notes for details).
* "git blame HEAD -- missing" failed to correctly say "HEAD" when it
tried to say "No such path 'missing' in HEAD".
(merge a46442f jk/blame-commit-label later to maint).
* "git rerere" (invoked internally from many mergy operations) did
not correctly signal errors when told to update the working tree
files and failed to do so for whatever reason.
(merge 89ea903 jn/rerere-fail-on-auto-update-failure later to maint).
* Setting diff.submodule to 'log' made "git format-patch" produce
broken patches.
(merge 339de50 dk/format-patch-ignore-diff-submodule later to maint).
* After attempting and failing a password-less authentication
(e.g. kerberos), libcURL refuses to fall back to password based
Basic authentication without a bit of help/encouragement.
(merge 4dbe664 bc/http-fallback-to-password-after-krb-fails later to maint).
* The "git push" documentation made the "--repo=<there>" option
easily misunderstood.
(merge 57b92a7 mg/push-repo-option-doc later to maint).
* Code to read branch name from various files in .git/ directory
would have misbehaved if the code to write them left an empty file.
(merge 66ec904 jk/status-read-branch-name-fix later to maint).
* A misspelled conditional that is always true has been fixed.
(merge 94ee8e2 jk/remote-curl-an-array-in-struct-cannot-be-null later to maint).
* The documentation incorrectly said that C(opy) and R(ename) are the
only ones that can be followed by the score number in the output in
the --raw format.
(merge ac1c2d9 jc/diff-format-doc later to maint).
* A broken pack .idx file in the receiving repository prevented the
dumb http transport from fetching a good copy of it from the other
side.
(merge 8b9c2dd jk/dumb-http-idx-fetch-fix later to maint).
* The error message from "git commit", when a non-existing author
name was given as value to the "--author=" parameter, has been
reworded to avoid misunderstanding.
(merge 1044b1f mg/commit-author-no-match-malformed-message later to maint).
* "git log --help" used to show rev-list options that are irrelevant
to the "log" command.
(merge 3cab02d jc/doc-log-rev-list-options later to maint).
* "git apply --whitespace=fix" used to under-allocate the memory when
the fix resulted in a longer text than the original patch.
(merge 407a792 jc/apply-ws-fix-expands later to maint).
* The interactive "show a list and let the user choose from it"
interface "add -i" used showed and prompted to the user even when
the candidate list was empty, against which the only "choice" the
user could have made was to choose nothing.
(merge a9c4641 ak/add-i-empty-candidates later to maint).
* The insn sheet "git rebase -i" creates did not fully honor
core.abbrev settings.
(merge edb72d5 ks/rebase-i-abbrev later to maint).
* "git fetch" over a remote-helper that cannot respond to "list"
command could not fetch from a symbolic reference e.g. HEAD.
(merge 33cae54 mh/deref-symref-over-helper-transport later to maint).
* "git push --signed" gave an incorrectly worded error message when
the other side did not support the capability.
(merge 45917f0 jc/push-cert later to maint).
* We didn't format an integer that wouldn't fit in "int" but in
"uintmax_t" correctly.
(merge d306f3d jk/decimal-width-for-uintmax later to maint).
* Reading configuration from a blob object, when it ends with a lone
CR, use to confuse the configuration parser.
(merge 1d0655c jk/config-no-ungetc-eof later to maint).
* The pack bitmap support did not build with older versions of GCC.
(merge bd4e882 jk/pack-bitmap later to maint).
* The documentation wasn't clear that "remote.<nick>.pushURL" and
"remote.<nick>.URL" are there to name the same repository accessed
via different transports, not two separate repositories.
(merge 697f652 jc/remote-set-url-doc later to maint).
* Older GnuPG implementations may not correctly import the keyring
material we prepare for the tests to use.
(merge 1f985d6 ch/new-gpg-drops-rfc-1991 later to maint).
* The credential helper for Windows (in contrib/) used to mishandle
a user name with an at-sign in it.
(merge 13d261e av/wincred-with-at-in-username-fix later to maint).
* Longstanding configuration variable naming rules has been added to
the documentation.
(merge 35840a3 jc/conf-var-doc later to maint).
* An earlier workaround to squelch unhelpful deprecation warnings
from the complier on Mac OSX unnecessarily set minimum required
version of the OS, which the user might want to raise (or lower)
for other reasons.
(merge 88c03eb es/squelch-openssl-warnings-on-macosx later to maint).
* Certain older vintages of cURL give irregular output from
"curl-config --vernum", which confused our build system.
(merge 3af6792 tc/curl-vernum-output-broken-in-7.11 later to maint).
* In v2.2.0, we broke "git prune" that runs in a repository that
borrows from an alternate object store.
(merge b0a4264 jk/prune-mtime later to maint).
* "git submodule add" failed to squash "path/to/././submodule" to
"path/to/submodule".
(merge 8196e72 ps/submodule-sanitize-path-upon-add later to maint).
* "git merge-file" did not work correctly in a subdirectory.
(merge 204a8ff ab/merge-file-prefix later to maint).
* "git blame" died, trying to free an uninitialized piece of memory.
(merge e600592 es/blame-commit-info-fix later to maint).
* "git fast-import" used to crash when it could not close and
conclude the resulting packfile cleanly.
(merge 5e915f3 jk/fast-import-die-nicely-fix later to maint).
* "update-index --refresh" used to leak when an entry cannot be
refreshed for whatever reason.
(merge bc1c2ca sb/plug-leak-in-make-cache-entry later to maint).
