In this release, these commands give a warning message that +suggests the users to use "git add -u/-A ." when they want to limit +the scope to the current directory; doing so will squelch the message, +while training their fingers. + + +Backward compatibility notes (for Git 2.0) +------------------------------------------ + +When "git push [$there]" does not say what to push, we have used the +traditional "matching" semantics so far (all your branches were sent +to the remote as long as there already are branches of the same name +over there). In Git 2.0, the default will change to the "simple" +semantics that pushes the current branch to the branch with the same +name, only when the current branch is set to integrate with that +remote branch. There is a user preference configuration variable +"push.default" to change this. If you are an old-timer who is used +to the "matching" semantics, you can set it to "matching" to keep the +traditional behaviour. If you want to live in the future early, +you can set it to "simple" today without waiting for Git 2.0. + +When "git add -u" and "git add -A", that does not specify what paths +to add on the command line is run from inside a subdirectory, these +commands will operate on the entire tree in Git 2.0 for consistency +with "git commit -a" and other commands. Because there will be no +mechanism to make "git add -u" behave as if "git add -u .", it is +important for those who are used to "git add -u" (without pathspec) +updating the index only for paths in the current subdirectory to start +training their fingers to explicitly say "git add -u ." when they mean +it before Git 2.0 comes. + + +Updates since v1.8.1 +-------------------- + +UI, Workflows & Features + + * Initial ports to QNX and z/OS UNIX System Services have started. + + * Output from the tests is coloured using "green is okay, yellow is + questionable, red is bad and blue is informative" scheme. + + * Mention of "GIT/Git/git" in the documentation have been updated to + be more uniform and consistent. The name of the system and the + concept it embodies is "Git"; the command the users type is "git". + All-caps "GIT" was merely a way to imitate "Git" typeset in small + caps in our ASCII text only documentation and to be avoided. + + * The completion script (in contrib/completion) used to let the + default completer to suggest pathnames, which gave too many + irrelevant choices (e.g. "git add" would not want to add an + unmodified path). It learnt to use a more git-aware logic to + enumerate only relevant ones. + + * In bare repositories, "git shortlog" and other commands now read + mailmap files from the tip of the history, to help running these + tools in server settings. + + * Color specifiers, e.g. "%C(blue)Hello%C(reset)", used in the + "--format=" option of "git log" and friends can be disabled when + the output is not sent to a terminal by prefixing them with + "auto,", e.g. "%C(auto,blue)Hello%C(auto,reset)". + + * Scripts can ask Git that wildcard patterns in pathspecs they give do + not have any significance, i.e. take them as literal strings. + + * The patterns in .gitignore and .gitattributes files can have **/, + as a pattern that matches 0 or more levels of subdirectory. + E.g. "foo/**/bar" matches "bar" in "foo" itself or in a + subdirectory of "foo". + + * When giving arguments without "--" disambiguation, object names + that come earlier on the command line must not be interpretable as + pathspecs and pathspecs that come later on the command line must + not be interpretable as object names. This disambiguation rule has + been tweaked so that ":/" (no other string before or after) is + always interpreted as a pathspec; "git cmd -- :/" is no longer + needed, you can just say "git cmd :/". + + * Various "hint" lines Git gives when it asks the user to edit + messages in the editor are commented out with '#' by default. The + core.commentchar configuration variable can be used to customize + this '#' to a different character. + + * "git add -u" and "git add -A" without pathspec issues warning to + make users aware that they are only operating on paths inside the + subdirectory they are in.

(everything from the $cwd) to disambiguate. + + * "git blame" (and "git diff") learned the "--no-follow" option. + + * "git branch" now rejects some nonsense combinations of command line + arguments (e.g. giving more than one branch name to rename) with + more case-specific error messages. + + * "git check-ignore" command to help debugging .gitignore files has + been added. + + * "git cherry-pick" can be used to replay a root commit to an unborn + branch. + + * "git commit" can be told to use --cleanup=whitespace by setting the + configuration variable commit.cleanup to 'whitespace'. + + * "git diff" and other Porcelain commands can be told to use a + non-standard algorithm by setting diff.algorithm configuration + variable. + + * "git fetch --mirror" and fetch that uses other forms of refspec + with wildcard used to attempt to update a symbolic ref that match + the wildcard on the receiving end, which made little sense (the + real ref that is pointed at by the symbolic ref would be updated + anyway).

This + allows patches from rerolled series to be stored under different + names and makes it easier to reuse cover letter messages. + + * "git log" and friends can be told with --use-mailmap option to + rewrite the names and email addresses of people using the mailmap + mechanism. + + * "git log --cc --graph" now shows the combined diff output with the + ancestry graph. + + * "git log --grep=<pattern>" honors i18n.logoutputencoding to look + for the pattern after fixing the log message to the specified + encoding. + + * "git mergetool" and "git difftool" learned to list the available + tool backends in a more consistent manner. + + * "git mergetool" is aware of TortoiseGitMerge now and uses it over + TortoiseMerge when available. + + * "git push" now requires "-f" to update a tag, even if it is a + fast-forward, as tags are meant to be fixed points. + + * Error messages from "git push" when it stops to prevent remote refs + from getting overwritten by mistake have been improved to explain + various situations separately. + + * "git push" will stop without doing anything if the new "pre-push" + hook exists and exits with a failure. + + * When "git rebase" fails to generate patches to be applied (e.g. due + to oom), it failed to detect the failure and instead behaved as if + there were nothing to do. A workaround to use a temporary file has + been applied, but we probably would want to revisit this later, as + it hurts the common case of not failing at all. + + * Input and preconditions to "git reset" has been loosened where + appropriate. "git reset $fromtree Makefile" requires $fromtree to + be any tree (it used to require it to be a commit), for example. + "git reset" (without options or parameters) used to error out when + you do not have any commits in your history, but it now gives you + an empty index (to match non-existent commit you are not even on). + + * "git status" says what branch is being bisected or rebased when + able, not just "bisecting" or "rebasing". + + * "git submodule" started learning a new mode to integrate with the + tip of the remote branch (as opposed to integrating with the commit + recorded in the superproject's gitlink). + + * "git upload-pack" which implements the service "ls-remote" and + "fetch" talk to can be told to hide ref hierarchies the server + side internally uses (and that clients have no business learning + about) with transfer.hiderefs configuration. + + +Foreign Interface + + * "git fast-export" has been updated for its use in the context of + the remote helper interface. + + * A new remote helper to interact with bzr has been added to contrib/. + + * "git p4" got various bugfixes around its branch handling.

In addition, its various + portability issues for Cygwin have been addressed. + + * The remote helper to interact with Hg in contrib/ has seen a few + fixes. + + +Performance, Internal Implementation, etc. + + * "git fsck" has been taught to be pickier about entries in tree + objects that should not be there, e.g. ".", ".git", and "..". + + * Matching paths with common forms of pathspecs that contain wildcard + characters has been optimized further. + + * We stopped paying attention to $GIT_CONFIG environment that points + at a single configuration file from any command other than "git config" + quite a while ago, but "git clone" internally set, exported, and + then unexported the variable during its operation unnecessarily. + + * "git reset" internals has been reworked and should be faster in + general. We tried to be careful not to break any behaviour but + there could be corner cases, especially when running the command + from a conflicted state, that we may have missed. + + * The implementation of "imap-send" has been updated to reuse xml + quoting code from http-push codepath, and lost a lot of unused + code. + + * There is a simple-minded checker for the test scripts in t/ + directory to catch most common mistakes (it is not enabled by + default). + + * You can build with USE_WILDMATCH=YesPlease to use a replacement + implementation of pattern matching logic used for pathname-like + things, e.g. refnames and paths in the repository. This new + implementation is not expected change the existing behaviour of Git + in this release, except for "git for-each-ref" where you can now + say "refs/**/master" and match with both refs/heads/master and + refs/remotes/origin/master. We plan to use this new implementation + in wider places (e.g. "git ls-files '**/Makefile' may find Makefile + at the top-level, and "git log '**/t*.sh'" may find commits that + touch a shell script whose name begins with "t" at any level) in + future versions of Git, but we are not there yet. By building with + USE_WILDMATCH, using the resulting Git daily and reporting when you + find breakages, you can help us get closer to that goal. + + * Some reimplementations of Git do not write all the stat info back + to the index due to their implementation limitations (e.g. jgit). + A configuration option can tell Git to ignore changes to most of + the stat fields and only pay attention to mtime and size, which + these implementations can reliably update.

There will be no +mechanism to make plain "git add -u" behave like "git add -u .". +Current users of "git add -u" (without a pathspec) should start +training their fingers to explicitly say "git add -u ." +before Git 2.0 comes. A warning is issued when these commands are +run without a pathspec and when you have local changes outside the +current directory, because the behaviour in Git 2.0 will be different +from today's version in such a situation. + +In Git 2.0, "git add <path>" will behave as "git add -A <path>", so +that "git add dir/" will notice paths you removed from the directory +and record the removal.

Make it honor the --no-textconv + option. + + * When used with the "-d temporary-directory" option, "git filter-branch" + failed to come back to the original working tree to perform the + final clean-up procedure. + + * "git merge $(git rev-parse v1.8.2)" behaved quite differently from + "git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did + not pay much attention to the annotated tag payload.

The meaning + of the option has been changed to always show "HEAD" regardless of + what filtering will be applied to any other ref. + + This is a backward incompatible change and might cause breakages to + people's existing scripts. + + * "git show -s" was less discoverable than it should have been. It + now has a natural synonym "git show --no-patch". + + * "git check-mailmap" is a new command that lets you map usernames + and e-mail addresses through the mailmap mechanism, just like many + built-in commands do. + + * "git name-rev" learned to name an annotated tag object back to its + tagname; "git name-rev $(git rev-parse v1.0.0)" gives "tags/v1.0.0", + for example. + + * "git cat-file --batch-check=<format>" is added, primarily to allow + on-disk footprint of objects in packfiles (often they are a lot + smaller than their true size, when expressed as deltas) to be + reported. + + * "git rebase [-i]" used to leave just "rebase" as its reflog messages + for some operations.

Now the variable defaults to "auto". + + * On Cygwin, "cygstart" is now recognised as a possible way to start + a web browser (used in "help -w" and "instaweb" among others). + + * "git status" learned status.branch and status.short configuration + variables to use --branch and --short options by default (override + with --no-branch and --no-short options from the command line). + + * "git cmd <name>", when <name> happens to be a 40-hex string, + directly uses the 40-hex string as an object name, even if a ref + "refs/<some hierarchy>/<name>" exists. This disambiguation order + is unlikely to change, but we should warn about the ambiguity just + like we warn when more than one refs/ hierarchies share the same + name. + + * "git rebase" learned "--[no-]autostash" option to save local + changes instead of refusing to run (to which people's normal + response was to stash them and re-run). This introduced a corner + case breakage to "git am --abort" but it has been fixed. + + * "check-ignore" (new feature since 1.8.2) has been updated to work + more like "check-attr" over bidi-pipes. + + * "git describe" learned "--first-parent" option to limit its closest + tagged commit search to the first-parent chain. + + * "git merge foo" that might have meant "git merge origin/foo" is + diagnosed with a more informative error message. + + * "git log -L<line>,<range>:<filename>" has been added.

The message has finally been removed. + + * "git fetch origin master" unlike "git fetch origin" or "git fetch" + did not update "refs/remotes/origin/master"; this was an early + design decision to keep the update of remote tracking branches + predictable, but in practice it turns out that people find it more + convenient to opportunistically update them whenever we have a + chance, and we have been updating them when we run "git push" which + already breaks the original "predictability" anyway. + + * The configuration variable core.checkstat was advertised in the + documentation but the code expected core.statinfo instead. + For now, we accept both core.checkstat and core.statinfo, but the + latter will be removed in the longer term. + + +Performance, Internal Implementation, etc. + + * On Cygwin, we used to use our own lstat(2) emulation that is + allegedly faster than the platform one in codepaths where some of + the information it returns did not matter, but it started to bite + us in a few codepaths where the trick it uses to cheat does show + breakages. This emulation has been removed and we use the native + lstat(2) emulation supplied by Cygwin now. + + * The function attributes extensions are used to catch mistakes in + use of our own variadic functions that use NULL sentinel at the end + (i.e. like execl(3)) and format strings (i.e. like printf(3)). + + * The code to allow configuration data to be read from in-tree blob + objects is in. This may help working in a bare repository and + submodule updates. + + * Fetching between repositories with many refs employed O(n^2) + algorithm to match up the common objects, which has been corrected. + + * The original way to specify remote repository using .git/branches/ + used to have a nifty feature. The code to support the feature was + still in a function but the caller was changed not to call it 5 + years ago, breaking that feature and leaving the supporting code + unreachable. The dead code has been removed. + + * "git pack-refs" that races with new ref creation or deletion have + been susceptible to lossage of refs under right conditions, which + has been tightened up. + + * We read loose and packed references in two steps, but after + deciding to read a loose ref but before actually opening it to read + it, another process racing with us can unlink it, which would cause + us to barf. The codepath has been updated to retry when such a + race is detected, instead of outright failing. + + * Uses of the platform fnmatch(3) function (many places in the code, + matching pathspec, .gitignore and .gitattributes to name a few) + have been replaced with wildmatch, allowing "foo/**/bar" that would + match foo/bar, foo/a/bar, foo/a/b/bar, etc. + + * Memory ownership and lifetime rules for what for-each-ref feeds to + its callbacks have been clarified (in short, "you do not own it, so + make a copy if you want to keep it"). + + * The revision traversal logic to improve culling of irrelevant + parents while traversing a mergy history has been updated. + + * Some leaks in unpack-trees (used in merge, cherry-pick and other + codepaths) have been plugged. + + * The codepath to read from marks files in fast-import/export did not + have to accept anything but 40-hex representation of the object + name. Further, fast-export did not need full in-core object + representation to have parsed wen reading from them. These + codepaths have been optimized by taking advantage of these access + patterns. + + * Object lookup logic, when the object hashtable starts to become + crowded, has been optimized. + + * When TEST_OUTPUT_DIRECTORY setting is used, it was handled somewhat + inconsistently between the test framework and t/Makefile, and logic + to summarize the results looked at a wrong place. + + * "git clone" uses a lighter-weight implementation when making sure + that the history behind refs are complete. + + * Many warnings from sparse source checker in compat/ area has been + squelched. + + * The code to reading and updating packed-refs file has been updated, + correcting corner case bugs. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v1.8.3 +------------------ + +Unless otherwise noted, all the fixes since v1.8.3 in the maintenance +track are contained in this release (see release notes to them for +details). + + * Newer Net::SMTP::SSL module does not want the user programs to use + the default behaviour to let server certificate go without + verification, so by default enable the verification with a + mechanism to turn it off if needed. + (merge 35035bb rr/send-email-ssl-verify later to maint). + + * When "git" is spawned in such a way that any of the low 3 file + descriptors is closed, our first open() may yield file descriptor 2, + and writing error message to it would screw things up in a big way. + (merge a11c396 tr/protect-low-3-fds later to maint). + + * The mailmap mechanism unnecessarily downcased the e-mail addresses + in the output, and also ignored the human name when it is a single + character name. + (merge bd23794 jc/mailmap-case-insensitivity later to maint). + + * In two places we did not check return value (expected to be a file + descriptor) correctly. + (merge a77f106 tr/fd-gotcha-fixes later to maint). + + * Logic to auto-detect character encodings in the commit log message + did not reject overlong and invalid UTF-8 characters. + (merge 81050ac bc/commit-invalid-utf8 later to maint). + + * Pass port number as a separate argument when "send-email" initializes + Net::SMTP, instead of as a part of the hostname, i.e. host:port. + This allows GSSAPI codepath to match with the hostname given. + (merge 1a741bf bc/send-email-use-port-as-separate-param later to maint). + + * "git diff" refused to even show difference when core.safecrlf is + set to true (i.e. error out) and there are offending lines in the + working tree files. + (merge 5430bb2 jc/maint-diff-core-safecrlf later to maint). + + * A test that should have failed but didn't revealed a bug that needs + to be corrected. + (merge 94d75d1 jc/t1512-fix later to maint). + + * An overlong path to a .git directory may have overflown the + temporary path buffer used to create a name for lockfiles. + (merge 2fbd4f9 mh/maint-lockfile-overflow later to maint). + + * Invocations of "git checkout" used internally by "git rebase" were + counted as "checkout", and affected later "git checkout -" to the + the user to an unexpected place. + (merge 3bed291 rr/rebase-checkout-reflog later to maint). + + * The configuration variable column.ui was poorly documented. + (merge 5e62cc1 rr/column-doc later to maint). + + * "git name-rev --refs=tags/v*" were forbidden, which was a bit + inconvenient (you had to give a pattern to match refs fully, like + --refs=refs/tags/v*). + (merge 98c5c4a nk/name-rev-abbreviated-refs later to maint). + + * "git apply" parsed patches that add new files, generated by + programs other than Git, incorrectly. This is an old breakage in + v1.7.11 and will need to be merged down to the maintenance tracks. + + * Older cURL wanted piece of memory we call it with to be stable, but + we updated the auth material after handing it to a call. + + * "git pull" into nothing trashed "local changes" that were in the + index, and this avoids it. + + * Many "git submodule" operations do not work on a submodule at a + path whose name is not in ASCII. + + * "cherry-pick" had a small leak in an error codepath. + + * Logic used by git-send-email to suppress cc mishandled names like + "A U. Thor" <author@example.xz>, where the human readable part + needs to be quoted (the user input may not have the double quotes + around the name, and comparison was done between quoted and + unquoted strings). It also mishandled names that need RFC2047 + quoting. + + * Call to discard_cache/discard_index (used when we use different + contents of the index in-core, in many operations like commit, + apply, and merge) used to leak memory that held the array of index + entries, which has been plugged. + (merge a0fc4db rs/discard-index-discard-array later to maint). + + * "gitweb" forgot to clear a global variable $search_regexp upon each + request, mistakenly carrying over the previous search to a new one + when used as a persistent CGI. + + * The wildmatch engine did not honor WM_CASEFOLD option correctly. + + * "git log -c --follow $path" segfaulted upon hitting the commit that + renamed the $path being followed. + + * When a reflog notation is used for implicit "current branch", we + did not say which branch and worse said "branch ''". + + * "difftool --dir-diff" did not copy back changes made by the + end-user in the diff tool backend to the working tree in some + cases. + + * "git push $there HEAD:branch" did not resolve HEAD early enough, so + it was easy to flip it around while push is still going on and push + out a branch that the user did not originally intended when the + command was started. + + * The bash prompt code (in contrib/) displayed the name of the branch + being rebased when "rebase -i/-m/-p" modes are in use, but not the + plain vanilla "rebase". + + * Handling of negative exclude pattern for directories "!dir" was + broken in the update to v1.8.3. + + * zsh prompt script that borrowed from bash prompt script did not + work due to slight differences in array variable notation between + these two shells. + + * An entry for "file://" scheme in the enumeration of URL types Git + can take in the HTML documentation was made into a clickable link + by mistake. + + * "git push --[no-]verify" was not documented. + + * Stop installing the git-remote-testpy script that is only used for + testing. + + * "git commit --allow-empty-message -m ''" should not start an + editor. + + * "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22" + incorrectly when your previous branch was "frotz" (it should be + rewritten to "git merge frotz~22" instead). + + * "git diff -c -p" was not showing a deleted line from a hunk when + another hunk immediately begins where the earlier one ends. + + * "git log --ancestry-path A...B" did not work as expected, as it did + not pay attention to the fact that the merge base between A and B + was the bottom of the range being specified. + + * Mac OS X does not like to write(2) more than INT_MAX number of + bytes; work it around by chopping write(2) into smaller pieces. + + * Newer MacOS X encourages the programs to compile and link with + their CommonCrypto, not with OpenSSL. + + * "git clone foo/bar:baz" cannot be a request to clone from a remote + over git-over-ssh specified in the scp style.

In Git 2.0, the default will change to the "simple" +semantics, which pushes: + + - only the current branch to the branch with the same name, and only + when the current branch is set to integrate with that remote + branch, if you are pushing to the same remote as you fetch from; or + + - only the current branch to the branch with the same name, if you + are pushing to a remote that is not where you usually fetch from. + +Use the user preference configuration variable "push.default" to +change this. If you are an old-timer who is used to the "matching" +semantics, you can set the variable to "matching" to keep the +traditional behaviour. If you want to live in the future early, you +can set it to "simple" today without waiting for Git 2.0. + +When "git add -u" (and "git add -A") is run inside a subdirectory and +does not specify which paths to add on the command line, it +will operate on the entire tree in Git 2.0 for consistency +with "git commit -a" and other commands. There will be no +mechanism to make plain "git add -u" behave like "git add -u .". +Current users of "git add -u" (without a pathspec) should start +training their fingers to explicitly say "git add -u ." +before Git 2.0 comes. A warning is issued when these commands are +run without a pathspec and when you have local changes outside the +current directory, because the behaviour in Git 2.0 will be different +from today's version in such a situation. + +In Git 2.0, "git add <path>" will behave as "git add -A <path>", so +that "git add dir/" will notice paths you removed from the directory +and record the removal. Versions before Git 2.0, including this +release, will keep ignoring removals, but the users who rely on this +behaviour are encouraged to start using "git add --ignore-removal <path>" +now before 2.0 is released. + +The default prefix for "git svn" will change in Git 2.0. For a long +time, "git svn" created its remote-tracking branches directly under +refs/remotes, but it will place them under refs/remotes/origin/ unless +it is told otherwise with its --prefix option. + + +Updates since v1.8.4 +-------------------- + +Foreign interfaces, subsystems and ports. + + * "git-svn" has been taught to use the serf library, which is the + only option SVN 1.8.0 offers us when talking the HTTP protocol. + + * "git-svn" talking over an https:// connection using the serf library + dumped core due to a bug in the serf library that SVN uses.

Careless users who forget to sufficiently quote $args +get their argument split at $IFS whitespaces by the shell, and got +unexpected results due to this. Starting from this release, the +command line is passed directly to the shell, if it has an argument. + +Read-only support for experimental loose-object format, in which users +could optionally choose to write their loose objects for a short +while between v1.4.3 and v1.5.3 era, has been dropped. + +The meanings of the "--tags" option to "git fetch" has changed; the +command fetches tags _in addition to_ what is fetched by the same +command line without the option. + +The way "git push $there $what" interprets the $what part given on the +command line, when it does not have a colon that explicitly tells us +what ref at the $there repository is to be updated, has been enhanced. + +A handful of ancient commands that have long been deprecated are +finally gone (repo-config, tar-tree, lost-found, and peek-remote). + + +Backward compatibility notes (for Git 2.0.0) +-------------------------------------------- + +When "git push [$there]" does not say what to push, we have used the +traditional "matching" semantics so far (all your branches were sent +to the remote as long as there already are branches of the same name +over there). In Git 2.0, the default will change to the "simple" +semantics, which pushes: + + - only the current branch to the branch with the same name, and only + when the current branch is set to integrate with that remote + branch, if you are pushing to the same remote as you fetch from; or + + - only the current branch to the branch with the same name, if you + are pushing to a remote that is not where you usually fetch from. + +Use the user preference configuration variable "push.default" to +change this. If you are an old-timer who is used to the "matching" +semantics, you can set the variable to "matching" to keep the +traditional behaviour. If you want to live in the future early, you +can set it to "simple" today without waiting for Git 2.0. + +When "git add -u" (and "git add -A") is run inside a subdirectory and +does not specify which paths to add on the command line, it +will operate on the entire tree in Git 2.0 for consistency +with "git commit -a" and other commands. There will be no +mechanism to make plain "git add -u" behave like "git add -u .". +Current users of "git add -u" (without a pathspec) should start +training their fingers to explicitly say "git add -u ." +before Git 2.0 comes. A warning is issued when these commands are +run without a pathspec and when you have local changes outside the +current directory, because the behaviour in Git 2.0 will be different +from today's version in such a situation. + +In Git 2.0, "git add <path>" will behave as "git add -A <path>", so +that "git add dir/" will notice paths you removed from the directory +and record the removal. Versions before Git 2.0, including this +release, will keep ignoring removals, but the users who rely on this +behaviour are encouraged to start using "git add --ignore-removal <path>" +now before 2.0 is released. + +The default prefix for "git svn" will change in Git 2.0. For a long +time, "git svn" created its remote-tracking branches directly under +refs/remotes, but it will place them under refs/remotes/origin/ unless +it is told otherwise with its --prefix option. + + +Updates since v1.8.5 +-------------------- + +Foreign interfaces, subsystems and ports. + + * The HTTP transport, when talking GSS-Negotiate, uses "100 + Continue" response to avoid having to rewind and resend a large + payload, which may not be always doable. + + * Various bugfixes to remote-bzr and remote-hg (in contrib/). + + * The build procedure is aware of MirBSD now. + + * Various "git p4", "git svn" and "gitk" updates. + + +UI, Workflows & Features + + * Fetching from a shallowly-cloned repository used to be forbidden, + primarily because the codepaths involved were not carefully vetted + and we did not bother supporting such usage. This release attempts + to allow object transfer out of a shallowly-cloned repository in a + more controlled way (i.e. the receiver becomes a shallow repository + with a truncated history). + + * Just like we give a reasonable default for "less" via the LESS + environment variable, we now specify a reasonable default for "lv" + via the "LV" environment variable when spawning the pager. + + * Two-level configuration variable names in "branch.*" and "remote.*" + hierarchies, whose variables are predominantly three-level, were + not completed by hitting a <TAB> in bash and zsh completions. + + * Fetching a 'frotz' branch with "git fetch", while a 'frotz/nitfol' + remote-tracking branch from an earlier fetch was still there, would + error out, primarily because the command was not told that it is + allowed to lose any information on our side. "git fetch --prune" + now can be used to remove 'frotz/nitfol' to make room for fetching and + storing the 'frotz' remote-tracking branch. + + * "diff.orderfile=<file>" configuration variable can be used to + pretend as if the "-O<file>" option were given from the command + line of "git diff", etc. + + * The negative pathspec syntax allows "git log -- . ':!dir'" to tell + us "I am interested in everything but 'dir' directory". + + * "git difftool" shows how many different paths there are in total, + and how many of them have been shown so far, to indicate progress. + + * "git push origin master" used to push our 'master' branch to update + the 'master' branch at the 'origin' repository. This has been + enhanced to use the same ref mapping "git push origin" would use to + determine what ref at the 'origin' to be updated with our 'master'. + For example, with this configuration + + [remote "origin"] + push = refs/heads/*:refs/review/* + + that would cause "git push origin" to push out our local branches + to corresponding refs under refs/review/ hierarchy at 'origin', + "git push origin master" would update 'refs/review/master' over + there. Alternatively, if push.default is set to 'upstream' and our + 'master' is set to integrate with 'topic' from the 'origin' branch, + running "git push origin" while on our 'master' would update their + 'topic' branch, and running "git push origin master" while on any + of our branches does the same. + + * "gitweb" learned to treat ref hierarchies other than refs/heads as + if they are additional branch namespaces (e.g. refs/changes/ in + Gerrit). + + * "git for-each-ref --format=..." learned a few formatting directives; + e.g. "%(color:red)%(HEAD)%(color:reset) %(refname:short) %(subject)". + + * The command string given to "git submodule foreach" is passed + directly to the shell, without being eval'ed. This is a backward + incompatible change that may break existing users. + + * "git log" and friends learned the "--exclude=<glob>" option, to + allow people to say "list history of all branches except those that + match this pattern" with "git log --exclude='*/*' --branches". + + * "git rev-parse --parseopt" learned a new "--stuck-long" option to + help scripts parse options with an optional parameter. + + * The "--tags" option to "git fetch" no longer tells the command to + fetch _only_ the tags. It instead fetches tags _in addition to_ + what are fetched by the same command line without the option. + + +Performance, Internal Implementation, etc. + + * When parsing a 40-hex string into the object name, the string is + checked to see if it can be interpreted as a ref so that a warning + can be given for ambiguity. The code kicked in even when the + core.warnambiguousrefs is set to false to squelch this warning, in + which case the cycles spent to look at the ref namespace were an + expensive no-op, as the result was discarded without being used. + + * The naming convention of the packfiles has been updated; it used to + be based on the enumeration of names of the objects that are + contained in the pack, but now it also depends on how the packed + result is represented---packing the same set of objects using + different settings (or delta order) would produce a pack with + different name. + + * "git diff --no-index" mode used to unnecessarily attempt to read + the index when there is one. + + * The deprecated parse-options macro OPT_BOOLEAN has been removed; + use OPT_BOOL or OPT_COUNTUP in new code. + + * A few duplicate implementations of prefix/suffix string comparison + functions have been unified to starts_with() and ends_with(). + + * The new PERLLIB_EXTRA makefile variable can be used to specify + additional directories Perl modules (e.g. the ones necessary to run + git-svn) are installed on the platform when building. + + * "git merge-base" learned the "--fork-point" mode, that implements + the same logic used in "git pull --rebase" to find a suitable fork + point out of the reflog entries for the remote-tracking branch the + work has been based on. "git rebase" has the same logic that can be + triggered with the "--fork-point" option. + + * A third-party "receive-pack" (the responder to "git push") can + advertise the "no-thin" capability to tell "git push" not to use + the thin-pack optimization. Our receive-pack has always been + capable of accepting and fattening a thin-pack, and will continue + not to ask "git push" to use a non-thin pack. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v1.8.5 +------------------ + +Unless otherwise noted, all the fixes since v1.8.5 in the maintenance +track are contained in this release (see the maintenance releases' notes +for details). + + * The pathspec matching code, while comparing two trees (e.g. "git + diff A B -- path1 path2") was too aggressive and failed to match + some paths when multiple pathspecs were involved. + + * "git repack --max-pack-size=8g" stopped being parsed correctly when + the command was reimplemented in C. + + * An earlier update in v1.8.4.x to "git rev-list --objects" with + negative ref had a performance regression. + (merge 200abe7 jk/mark-edges-uninteresting later to maint). + + * A recent update to "git send-email" broke platforms where + /etc/ssl/certs/ directory exists but cannot be used as SSL_ca_path + (e.g. Fedora rawhide). + + * A handful of bugs around interpreting $branch@{upstream} notation + and its lookalike, when $branch part has interesting characters, + e.g. "@", and ":", have been fixed. + + * "git clone" would fail to clone from a repository that has a ref + directly under "refs/", e.g. "refs/stash", because different + validation paths do different things on such a refname.

The new GIT_TEST_CHAIN_LINT mechanism allows you to + catch such a mistake more easily. + + +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 it attempted to update the working + tree files but failed 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 for the "--repo=<there>" option was + easily misunderstood. + (merge 57b92a7 mg/push-repo-option-doc later to maint). + + * Code to read a branch name from various files in the .git/ + directory would have overrun array limits if asked to read an empty + file. + (merge 66ec904 jk/status-read-branch-name-fix later to maint). + + * Remove a superfluous conditional that is always true. + (merge 94ee8e2 jk/remote-curl-an-array-in-struct-cannot-be-null later to maint). + + * The "git diff --raw" documentation incorrectly implied that C(opy) + and R(ename) are the only statuses that can be followed by a score + number. + (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 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 used by "git add -i" unnecessarily prompted 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 todo list created by "git rebase -i" 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 the "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. + + * The "git push --signed" protocol extension did not limit what the + "nonce" (a server-chosen string) could contain nor how long it + could be, which was unnecessarily lax. Limit both the length and + the alphabet to a reasonably small space that can still have enough + entropy. + (merge afcb6ee jc/push-cert later to maint). + + * The completion script (in contrib/) clobbered the shell variable $x + in the global shell namespace. + (merge 852ff1c ma/bash-completion-leaking-x later to maint). + + * We incorrectly formatted a "uintmax_t" integer that doesn't fit in + "int". + (merge d306f3d jk/decimal-width-for-uintmax later to maint). + + * The configuration parser used to be confused when reading + configuration from a blob object that ends with a lone CR. + (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 + user names that contain an at-sign. + (merge 13d261e av/wincred-with-at-in-username-fix later to maint). + + * "diff-highlight" (in contrib/) used to show byte-by-byte + differences, which could cause multi-byte characters to be chopped + in the middle. It learned to pay attention to character boundaries + (assuming UTF-8). + (merge 8d00662 jk/colors later to maint). + + * Document longstanding configuration variable naming rules in + CodingGuidelines. + (merge 35840a3 jc/conf-var-doc later to maint). + + * An earlier workaround to squelch unhelpful deprecation warnings + from the compiler on OS X unnecessarily set a 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 when invoked in a + subdirectory. + (merge 204a8ff ab/merge-file-prefix later to maint). + + * "git blame" could die 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 + finalize the resulting packfile cleanly. + (merge 5e915f3 jk/fast-import-die-nicely-fix later to maint). + + * "update-index --refresh" used to leak memory when an entry could + not be refreshed for whatever reason. + (merge bc1c2ca sb/plug-leak-in-make-cache-entry later to maint). + + * The "interpolated-path" option of "git daemon" inserted any string + the client declared on the "host=" capability request without + checking. Sanitize and limit %H and %CH to a saner and a valid DNS + name. + (merge b485373 jk/daemon-interpolate later to maint). + + * "git daemon" unnecessarily looked up the hostname even when "%CH" + and "%IP" interpolations were not requested. + (merge dc8edc8 rs/daemon-interpolate later to maint). + + * We relied on "--no-" prefix handling in Perl's Getopt::Long + package, even though that support didn't exist in Perl 5.8 (which + we still support). Manually add support to help people with older + Getopt::Long packages. + (merge f471494 km/send-email-getopt-long-workarounds later to maint). + + * "git apply" was not very careful about reading from, removing, + updating and creating paths outside the working tree (under + --index/--cached) or the current directory (when used as a + replacement for GNU patch). + (merge e0d201b jc/apply-beyond-symlink later to maint). + + * Correct a breakage in git-svn, introduced around the v2.2 era, that + can cause FileHandles to be closed prematurely. + (merge e426311 ew/svn-maint-fixes later to maint). + + * We did not parse usernames followed by literal IPv6 addresses + correctly in SSH transport URLs; e.g., + ssh://user@[2001:db8::1]:22/repo.git. + (merge 6b6c5f7 tb/connect-ipv6-parse-fix later to maint). + + * The configuration variable 'mailinfo.scissors' was hard to + discover in the documentation. + (merge afb5de7 mm/am-c-doc later to maint). + + * The interaction between "git submodule update" and the + submodule.*.update configuration was not clearly documented. + (merge 5c31acf ms/submodule-update-config-doc later to maint). + + * "git diff --shortstat" used together with "--dirstat=changes" or + "--dirstat=files" incorrectly output dirstat information twice. + (merge ab27389 mk/diff-shortstat-dirstat-fix later to maint). + + * The manpage for "git remote add" mentioned "--tags" and "--no-tags" + but did not explain what happens if neither option is provided. + (merge aaba0ab mg/doc-remote-tags-or-not later to maint). + + * The description of "--exclude-standard option" in the output of + "git grep -h" was phrased poorly. + (merge 77fdb8a nd/grep-exclude-standard-help-fix later to maint). + + * "git rebase -i" recently started to include the number of commits + in the todo list, but that output included extraneous whitespace on + a platform that prepends leading whitespaces to its "wc -l" output. + (merge 2185d3b es/rebase-i-count-todo later to maint). + + * The borrowed code in the kwset API did not follow our usual + convention to use "unsigned char" to store values that range from + 0-255. + (merge 189c860 bw/kwset-use-unsigned later to maint). + + * A corrupt input to "git diff -M" used to cause it to segfault. + (merge 4d6be03 jk/diffcore-rename-duplicate later to maint). + + * Certain builds of GPG triggered false breakages in a test. + (merge 3f88c1b mg/verify-commit later to maint). + + * "git imap-send" learned to optionally talk with an IMAP server via + libcURL. Because there is no other option when Git is built with + the NO_OPENSSL option, use libcURL by default in that case. + (merge dcd01ea km/imap-send-libcurl-options later to maint). + + * "git log --decorate" did not reset colors correctly around the + branch names. + (merge 5ee8758 jc/decorate-leaky-separator-color later to maint). + + * The code that reads from the ctags file in the completion script + (in contrib/) did not spell ${param/pattern/string} substitution + correctly, which happened to work with bash but not with zsh. + (merge db8d750 js/completion-ctags-pattern-substitution-fix later to maint). + + * The transfer.hiderefs support did not quite work for smart-http + transport. + (merge 8ddf3ca jk/smart-http-hide-refs later to maint). + + * In the "git tag -h" output, move the documentation for the + "--column" and "--sort" options to the "Tag listing options" + section. + (merge dd059c6 jk/tag-h-column-is-a-listing-option later to maint). + + * "git prune" used to largely ignore broken refs when deciding which + objects are still being used, which could cause reference + corruption to lead to object loss. + (merge ea56c4e jk/prune-with-corrupt-refs later to maint). + + * The split-index mode introduced in v2.3.0-rc0~41 was broken in the + codepath to protect us against a broken reimplementation of Git + that writes an invalid index with duplicated index entries, etc. + (merge 03f15a7 tg/fix-check-order-with-split-index later to maint). + + * "git fetch", when fetching a commit using the + allow-tip-sha1-in-want extension, could have failed to fetch all of + the requested refs. + (merge 32d0462 jk/fetch-pack later to maint). + + * An failure early in the "git clone" that started creating the + working tree and repository could have resulted in the failure to + clean up some directories and files. + (merge 16eff6c jk/cleanup-failed-clone later to maint). + + * Recommend format-patch and send-email for those who want to submit + patches to this project. + (merge b25c469 jc/submitting-patches-mention-send-email later to maint). + + * Do not spawn the pager when "git grep" is run with "--quiet". + (merge c2048f0 ws/grep-quiet-no-pager later to maint). + + * The prompt script (in contrib/) did not show the untracked sign + when working in a subdirectory without any untracked files. + (merge 9bdc517 ct/prompt-untracked-fix later to maint). + + * An earlier update to the URL parser broke an address that contains + a colon but an empty string for the port number, like + ssh://example.com:/path/to/repo. + (merge 6b6c5f7 tb/connect-ipv6-parse-fix later to maint). + + * Code cleanups and documentation updates. + (merge 2ce63e9 rs/simple-cleanups later to maint). + (merge 33baa69 rj/no-xopen-source-for-cygwin later to maint). + (merge 817d03e jc/diff-test-updates later to maint). + (merge eb32c66 ak/t5516-typofix later to maint). + (merge bcd57cb mr/doc-clean-f-f later to maint). + (merge 0d6accc mg/doc-status-color-slot later to maint). + (merge 53e53c7 sg/completion-remote later to maint). + (merge 8fa7975 ak/git-done-help-cleanup later to maint). + (merge 9a6f128 rs/deflate-init-cleanup later to maint). + (merge 6f75d45 rs/use-isxdigit later to maint). + (merge 376e4b3 jk/test-annoyances later to maint). + (merge 7032054 nd/doc-git-index-version later to maint). + (merge e869c5e tg/test-index-v4 later to maint). + (merge 599d223 jk/simplify-csum-file-sha1fd-check later to maint). + (merge 260d585 sg/completion-gitcomp-nl-for-refs later to maint). + (merge 777c55a jc/report-path-error-to-dir later to maint). + (merge fddfaf8 ph/push-doc-cas later to maint). + (merge d50d31e ss/pull-rebase-preserve later to maint). + (merge c8c3f1d pt/enter-repo-comment-fix later to maint). + (merge d7bfb9e jz/gitweb-conf-doc-fix later to maint). + (merge f907282 jk/cherry-pick-docfix later to maint). + (merge d3c0811 iu/fix-parse-options-h-comment later to maint). + (merge 6c3b2af jg/cguide-we-cannot-count later to maint). + (merge 2b8bd44 jk/pack-corruption-post-mortem later to maint). + (merge 9585cb8 jn/doc-fast-import-no-16-octopus-limit later to maint). + (merge 5dcd1b1 ps/grep-help-all-callback-arg later to maint). + (merge f1f4c84 va/fix-git-p4-tests later to maint). |
