In Git 2.0, the default will change to the "simple" +semantics that 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. 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. + + +Updates since v1.8.2 +-------------------- + +Foreign interface + + * remote-hg and remote-bzr helpers (in contrib/ since v1.8.2) have + been updated; especially, the latter has been done in an + accelerated schedule (read: we may not have merged to this release + if we were following the usual "cook sufficiently in next before + unleashing it to the world" workflow) in order to help Emacs folks, + whose primary SCM seems to be stagnating. + + +UI, Workflows & Features + + * A handful of updates applied to gitk, including an addition of + "revert" action, showing dates in tags in a nicer way, making + colors configurable, and support for -G'pickaxe' search. + + * The prompt string generator (in contrib/completion/) learned to + show how many changes there are in total and how many have been + replayed during a "git rebase" session. + + * "git branch --vv" learned to paint the name of the branch it + integrates with in a different color (color.branch.upstream, + which defaults to blue). + + * In a sparsely populated working tree, "git checkout <pathspec>" no + longer unmarks paths that match the given pathspec that were + originally ignored with "--sparse" (use --ignore-skip-worktree-bits + option to resurrect these paths out of the index if you really want + to). + + * "git log --format" specifier learned %C(auto) token that tells Git + to use color when interpolating %d (decoration), %h (short commit + object name), etc. for terminal output. + + * "git bisect" leaves the final outcome as a comment in its bisect + log file. + + * "git clone --reference" can now refer to a gitfile "textual symlink" + that points at the real location of the repository. + + * "git count-objects" learned "--human-readable" aka "-H" option to + show various large numbers in Ki/Mi/GiB scaled as necessary. + + * "git cherry-pick $blob" and "git cherry-pick $tree" are nonsense, + and a more readable error message e.g. "can't cherry-pick a tree" + is given (we used to say "expected exactly one commit"). + + * The "--annotate" option to "git send-email" can be turned on (or + off) by default with sendemail.annotate configuration variable (you + can use --no-annotate from the command line to override it). + + * The "--cover-letter" option to "git format-patch" can be turned on + (or off) by default with format.coverLetter configuration + variable. By setting it to 'auto', you can turn it on only for a + series with two or more patches. + + * The bash completion support (in contrib/) learned that cherry-pick + takes a few more options than it already knew about. + + * "git help" learned "-g" option to show the list of guides just like + list of commands are given with "-a". + + * A triangular "pull from one place, push to another place" workflow + is supported better by new remote.pushdefault (overrides the + "origin" thing) and branch.*.pushremote (overrides the + branch.*.remote) configuration variables. + + * "git status" learned to report that you are in the middle of a + revert session, just like it does for a cherry-pick and a bisect + session. + + * The handling by "git branch --set-upstream-to" against various forms + of erroneous inputs was suboptimal and has been improved. + + * When the interactive access to git-shell is not enabled, it issues + a message meant to help the system administrator to enable it. An + explicit way has been added to issue custom messages to refuse an + access over the network to help the end users who connect to the + service expecting an interactive shell. + + * In addition to the case where the user edits the log message with + the "e)dit" option of "am -i", replace the "Applying: this patch" + message with the final log message contents after applymsg hook + munges it. + + * "git status" suggests users to look into using --untracked=no option + when it takes too long. + + * "git status" shows a bit more information during a rebase/bisect + session. + + * "git fetch" learned to fetch a commit at the tip of an unadvertised + ref by specifying a raw object name from the command line when the + server side supports this feature. + + * Output from "git log --graph" works better with submodule log + output now. + + * "git count-objects -v" learned to report leftover temporary + packfiles and other garbage in the object store. + + * A new read-only credential helper (in contrib/) to interact with + the .netrc/.authinfo files has been added. + + * "git send-email" can be used with the credential helper system. + + * There was no Porcelain way to say "I no longer am interested in + this submodule", once you express your interest in a submodule with + "submodule init". "submodule deinit" is the way to do so. + + * "git pull --rebase" learned to pass "-v/-q" options to underlying + "git rebase". + + * The new "--follow-tags" option tells "git push" to push relevant + annotated tags when pushing branches out. + + * "git merge" and "git pull" can optionally be told to inspect and + reject when merging a commit that does not carry a trusted GPG + signature. + + * "git mergetool" now feeds files to the "p4merge" backend in the + order that matches the p4 convention, where "theirs" is usually + shown on the left side, which is the opposite from what other backends + expect. + + * "show/log" now honors gpg.program configuration just like other + parts of the code that use GnuPG. + + * "git log" that shows the difference between the parent and the + child has been optimized somewhat. + + * "git difftool" allows the user to write into the temporary files + being shown; if the user makes changes to the working tree at the + same time, it now refrains from overwriting the copy in the working + tree and leaves the temporary file so that changes can be merged + manually. + + * There was no good way to ask "I have a random string that came from + outside world. I want to turn it into a 40-hex object name while + making sure such an object exists". A new peeling suffix ^{object} + can be used for that purpose, together with "rev-parse --verify". + + +Performance, Internal Implementation, etc. + + * Updates for building under msvc. + + * A handful of issues in the code that traverses the working tree to find + untracked and/or ignored files have been fixed, and the general + codepath involved in "status -u" and "clean" have been cleaned up + and optimized. + + * The stack footprint of some codepaths that access an object from a + pack has been shrunk. + + * The logic to coalesce the same lines removed from the parents in + the output from "diff -c/--cc" has been updated, but with O(n^2) + complexity, so this might turn out to be undesirable. + + * The code to enforce permission bits on files in $GIT_DIR/ for + shared repositories has been simplified. + + * A few codepaths know how much data they need to put in the + hashtables they use when they start, but still began with small tables + and repeatedly grew and rehashed them. + + * The API to walk reflog entries from the latest to older, which was + necessary for operations such as "git checkout -", was cumbersome + to use correctly and also inefficient. + + * Codepaths that inspect log-message-to-be and decide when to add a + new Signed-off-by line in various commands have been consolidated. + + * The pkt-line API, implementation and its callers have been cleaned + up to make them more robust. + + * The Cygwin port has a faster-but-lying lstat(2) emulation whose + incorrectness does not matter in practice except for a few + codepaths, and setting permission bits on directories is a codepath + that needs to use a more correct one. + + * "git checkout" had repeated pathspec matches on the same paths, + which have been consolidated. Also a bug in "git checkout dir/" + that is started from an unmerged index has been fixed. + + * A few bugfixes to "git rerere" working on corner case merge + conflicts have been applied. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v1.8.2 +------------------ + +Unless otherwise noted, all the fixes since v1.8.2 in the maintenance +track are contained in this release (see release notes to them for +details). + + * Recent versions of File::Temp (used by "git svn") started blowing + up when its tempfile sub is called as a class method; updated the + callsite to call it as a plain vanilla function to fix it. + (merge eafc2dd hb/git-pm-tempfile later to maint). + + * Various subcommands of "git remote" simply ignored extraneous + command line arguments instead of diagnosing them as errors. + + * When receive-pack detects an error in the pack header it received in + order to decide which of unpack-objects or index-pack to run, it + returned without closing the error stream, which led to a hung + sideband thread. + + * Zsh completion forgot that the '%' character used to signal untracked + files needs to be escaped with another '%'. + + * A commit object whose author or committer ident are malformed + crashed some code that trusted that a name, an email and a + timestamp can always be found in it. + + * When "upload-pack" fails while generating a pack in response to + "git fetch" (or "git clone"), the receiving side had + a programming error that triggered the die handler + recursively. + + * "rev-list --stdin" and friends kept bogus pointers into the input + buffer around as human readable object names. This was not a huge + problem but was exposed by a new change that uses these names in + error output. + + * Smart-capable HTTP servers were not restricted via the + GIT_NAMESPACE mechanism when talking with commit-walking clients, + like they are when talking with smart HTTP clients. + (merge 6130f86 jk/http-dumb-namespaces later to maint). + + * "git merge-tree" did not omit a merge result that is identical to + the "our" side in certain cases. + (merge aacecc3 jk/merge-tree-added-identically later to maint). + + * Perl scripts like "git-svn" closed (instead of redirecting to /dev/null) + the standard error stream, which is not a very smart thing to do. + A later open may return file descriptor #2 for an unrelated purpose, and + error reporting code may write into it. + + * "git show-branch" was not prepared to show a very long run of + ancestor operators e.g. foobar^2~2^2^2^2...^2~4 correctly. + + * "git diff --diff-algorithm algo" is also understood as "git diff + --diff-algorithm=algo". + + * The new core.commentchar configuration was not applied in a few + places. + + * "git bundle" erroneously bailed out when parsing a valid bundle + containing a prerequisite commit without a commit message. + + * "git log -S/-G" started paying attention to textconv filter, but + there was no way to disable this. 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. Make the code + notice the type of the tag object, in addition to the dwim_ref() + based classification the current code uses (i.e. the name appears + in refs/tags/) to decide when to special-case tag merging. + + * Fix a 1.8.1.x regression that stopped matching "dir" (without a + trailing slash) to a directory "dir". + + * "git apply --whitespace=fix" was not prepared to see a line getting + longer after fixing whitespaces (e.g. tab-in-indent aka Python). + + * The prompt string generator (in contrib/completion/) did not notice + when we are in a middle of a "git revert" session. + + * "submodule summary --summary-limit" option did not support the + "--option=value" form. + + * "index-pack --fix-thin" used an uninitialized value to compute + the delta depths of objects it appends to the resulting pack. + + * "index-pack --verify-stat" used a few counters outside the protection + of a mutex, possibly showing incorrect numbers. + + * The code to keep track of what directory names are known to Git on + platforms with case insensitive filesystems could get confused upon a + hash collision between these pathnames and would loop forever. + + * Annotated tags outside the refs/tags/ hierarchy were not advertised + correctly to ls-remote and fetch with recent versions of Git. + + * Recent optimizations broke shallow clones. + + * "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and + instead the parser kept reading beyond the end of the string. + + * "git tag -f <tag>" always said "Updated tag '<tag>'" even when + creating a new tag (i.e. neither overwriting nor updating). + + * "git p4" did not behave well when the path to the root of the P4 + client was not its real path. + (merge bbd8486 pw/p4-symlinked-root later to maint). + + * "git archive" reported a failure when asked to create an archive out + of an empty tree.

This may + still have leaks and rough edges, though. + + * We used the approxidate() parser for "--expire=<timestamp>" options + of various commands, but it is better to treat --expire=all and + --expire=now a bit more specially than using the current timestamp. + "git gc" and "git reflog" have been updated with a new parsing + function for expiry dates. + + * Updates to completion (both bash and zsh) helpers. + + * The behaviour of the "--chain-reply-to" option of "git send-email" + have changed at 1.7.0, and we added a warning/advice message to + help users adjust to the new behaviour back then, but we kept it + around for too long. 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. + + * "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 rerferences 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). + + * "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 maintanance tracks. + (merge 212eb96 tr/maint-apply-non-git-patch-parsefix later to maint). + + * 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. + (merge a94cf2c bc/http-keep-memory-given-to-curl later to maint). + + * "git pull" into nothing trashed "local changes" that were in the + index, and this avoids it. + (merge b4dc085 jk/pull-into-dirty-unborn later to maint). + + * Many "git submodule" operations do not work on a submodule at a + path whose name is not in ASCII. + (merge bed9470 fg/submodule-non-ascii-path later to maint). + + * "cherry-pick" had a small leak in an error codepath. + (merge 706728a fc/sequencer-plug-leak later to maint). + + * 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. + (merge 1495266 mt/send-email-cc-match-fix later to maint). + + * 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. + (merge ca7a5dc cm/gitweb-project-list-persistent-cgi-fix later to maint). + + * The wildmatch engine did not honor WM_CASEFOLD option correctly. + (merge b79c0c3 ar/wildmatch-foldcase later to maint). + + * "git log -c --follow $path" segfaulted upon hitting the commit that + renamed the $path being followed. + (merge 46ec510 cb/log-follow-with-combined later to maint). + + * When a reflog notation is used for implicit "current branch", we + did not say which branch and worse said "branch ''". + (merge 305ebea rr/die-on-missing-upstream later to maint). + + * "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. + (merge 32eaf1d ks/difftool-dir-diff-copy-fix later to maint). + + * "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. + (merge 0f075b2 rr/push-head later to maint). + + * 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". + (merge 1306321 fc/show-branch-in-rebase-am later to maint). + + * Handling of negative exclude pattern for directories "!dir" was + broken in the update to v1.8.3. + (merge c3c327d kb/status-ignored-optim-2 later to maint). + + * zsh prompt script that borrowed from bash prompt script did not + work due to slight differences in array variable notation between + these two shells. + (merge d0583da tg/maint-zsh-svn-remote-prompt later to maint). + + * 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. + (merge 4c32e36 nd/urls-doc-no-file-hyperlink-fix later to maint). + + * "git push --[no-]verify" was not documented. + (merge 90d32d1 tr/push-no-verify-doc later to maint). + + * Stop installing the git-remote-testpy script that is only used for + testing. + (merge 416fda6 fc/makefile later to maint). + + * "git commit --allow-empty-message -m ''" should not start an + editor. + (merge 2520677 rs/commit-m-no-edit later to maint). + + * "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). + (merge 84cf246 jc/strbuf-branchname-fix later to maint). + + * "git diff -c -p" was not showing a deleted line from a hunk when + another hunk immediately begins where the earlier one ends. + (merge aac3857 mk/combine-diff-context-horizon-fix later to maint). + + * "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. + (merge a765499 kb/ancestry-path-threedots later to maint). + + * 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. + (merge 6c642a8 fc/macos-x-clipped-write later to maint). + + * Newer MacOS X encourages the programs to compile and link with + their CommonCrypto, not with OpenSSL. + (merge be4c828 da/darwin later to maint). + + * "git clone foo/bar:baz" cannot be a request to clone from a remote + over git-over-ssh specified in the scp style. This case is now + detected and clones from a local repository at "foo/bar:baz". + (merge 6000334 nd/clone-local-with-colon later to maint). + + * When $HOME is misconfigured to point at an unreadable directory, we + used to complain and die. Loosen the check. + (merge 4698c8f jn/config-ignore-inaccessible later to maint). + + * "git subtree" (in contrib/) had one codepath with loose error + checks to lose data at the remote side. + (merge 3212d56 jk/subtree-do-not-push-if-split-fails later to maint). + + * "git fetch" into a shallow repository from a repository that does + not know about the shallow boundary commits (e.g. a different fork + from the repository the current shallow repository was cloned from) + did not work correctly. + (merge 71d5f93 mh/fetch-into-shallow later to maint). + + * "git checkout foo" DWIMs the intended "upstream" and turns it into + "git checkout -t -b foo remotes/origin/foo". This codepath has been + updated to correctly take existing remote definitions into account. + (merge 229177a jh/checkout-auto-tracking later to maint). |
