We will use 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. + + +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. + + * 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 pathspec code learned to grok "foo/**/bar" as a pattern that + matches "bar" in 0-or-more levels of subdirectory in "foo". + + * "git blame" (and "git diff") learned the "--no-follow" option. + + * "git cherry-pick" can be used to replay a root commit to an unborn + branch. + + * "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). Symbolic refs no longer are affected by such a fetch. + + * "git format-patch" now detects more cases in which a whole branch + is being exported, and uses the description for the branch, when + asked to write a cover letter for the series. + + * "git format-patch" learned "-v $count" option, and prepends a + string "v$count-" to the names of its output files, and also + automatically sets the subject prefix to "PATCH v$count". This + allows patches from rerolled series to be stored under different + names and makes it easier to reuse cover letter messsages. + + * "git push" now requires "-f" to update a tag, even if it is a + fast-forward, as tags are meant to be fixed points. + + * 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. + + * "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). + + +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/. + + +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. + + * The implementation of "imap-send" has been updated to reuse xml + quoting code from http-push codepath. + + * There is a simple-minded checker for the test scripts in t/ + directory to catch most common mistakes (it is not enabled by + default). + + +Also contains minor documentation updates and code clean-ups. + + +Fixes since v1.8.1 +------------------ + +Unless otherwise noted, all the fixes since v1.8.1 in the maintenance +track are contained in this release (see release notes to them for +details). + + * An element on GIT_CEILING_DIRECTORIES list that does not name the + real path to a directory (i.e. a symbolic link) could have caused + the GIT_DIR discovery logic to escape the ceiling. + (merge 059b379 mh/ceiling later to maint). + + * When attempting to read the XDG-style $HOME/.config/git/config and + finding that $HOME/.config/git is a file, we gave a wrong error + message, instead of treating the case as "a custom config file does + not exist there" and moving on. + (merge 8f2bbe4 jn/warn-on-inaccessible-loosen later to maint). + + * The behaviour visible to the end users was confusing, when they + attempt to kill a process spawned in the editor that was in turn + launched by Git with SIGINT (or SIGQUIT), as Git would catch that + signal and die. We ignore these signals now. + (merge 1250857 pf/editor-ignore-sigint later to maint). + + * A child process that was killed by a signal (e.g. SIGINT) was + reported in an inconsistent way depending on how the process was + spawned by us, with or without a shell in between. + (merge 709ca73 jk/unify-exit-code-by-receiving-signal later to maint). + + * After failing to create a temporary file using mkstemp(), failing + pathname was not reported correctly on some platforms. + (merge f7be59b jc/mkstemp-more-careful-error-reporting later to maint). + + * The attribute mechanism didn't allow limiting attributes to be + applied to only a single directory itself with "path/" like the + exclude mechanism does. + (merge 94bc671 ja/directory-attrs later to maint). + + * "git apply" misbehaved when fixing whitespace breakages by removing + excess trailing blank lines. + (merge 5de7166 jc/apply-trailing-blank-removal later to maint). + + * A tar archive created by "git archive" recorded a directory in a + way that made NetBSD's implementation of "tar" sometimes unhappy. + (merge 22f0dcd rs/leave-base-name-in-name-field-of-tar later to maint). + + * "git archive" did not record uncompressed size in the header when + streaming a zip archive, which confused some implementations of unzip. + (merge 5ea2c84 rs/zip-with-uncompressed-size-in-the-header later to maint). + + * When "git clone --separate-git-dir=$over_there" is interrupted, it + failed to remove the real location of the $GIT_DIR it created. + This was most visible when interrupting a submodule update. + (merge 9be1980 jl/interrupt-clone-remove-separate-git-dir later to maint). + + * The way "git svn" asked for password using SSH_ASKPASS and + GIT_ASKPASS was not in line with the rest of the system. + (merge e9263e4 ss/svn-prompt later to maint). + + * The --graph code fell into infinite loop when asked to do what the + code did not expect. + (merge 656197a mk/maint-graph-infinity-loop later to maint). + + * http transport was wrong to ask for the username when the + authentication is done by certificate identity. + (merge 75e9a40 rb/http-cert-cred-no-username-prompt later to maint). + + * "git pack-refs" that ran in parallel to another process that + created new refs had a nasty race. + (merge b3f1280 jk/repack-ref-racefix later to maint). + + * After "git add -N" and then writing a tree object out of the + index, the cache-tree data structure got corrupted. + (merge eec3e7e nd/invalidate-i-t-a-cache-tree later to maint). + + * "git merge --no-edit" computed who were involved in the work done + on the side branch, even though that information is to be discarded + without getting seen in the editor. + (merge 9bcbb1c jc/maint-fmt-merge-msg-no-edit-lose-credit later to maint). + + * "git merge" started calling prepare-commit-msg hook like "git + commit" does some time ago, but forgot to pay attention to the exit + status of the hook. + (merge 3e4141d ap/merge-stop-at-prepare-commit-msg-failure later to maint). + + * When users spell "cc:" in lowercase in the fake "header" in the + trailer part, "git send-email" failed to pick up the addresses from + there. As e-mail headers field names are case insensitive, this + script should follow suit and treat "cc:" and "Cc:" the same way. + (merge 6310071 nz/send-email-headers-are-case-insensitive later to maint). + + * Output from "git status --ignored" showed an unexpected interaction + with "--untracked". + (merge a45fb69 ap/status-ignored-in-ignored-directory later to maint). + + * "gitweb", when sorting by age to show repositories with new + activities first, used to sort repositories with absolutely + nothing in it early, which was not very useful. + (merge 28dae18 md/gitweb-sort-by-age later to maint). + + * "gitweb"'s code to sanitize control characters before passing it to + "highlight" filter lost known-to-be-safe control characters by + mistake. + (merge 0e901d2 os/gitweb-highlight-uncaptured later to maint). + + * When a line to be wrapped has a solid run of non space characters + whose length exactly is the wrap width, "git shortlog -w" failed + to add a newline after such a line. + (merge e0db176 sp/shortlog-missing-lf later to maint). + + * Some shells do not behave correctly when IFS is unset; work it + around by explicitly setting it to the default value. + (merge 393050c jc/maint-fbsd-sh-ifs-workaround later to maint). + + * Some scripted programs written in Python did not get updated when + PYTHON_PATH changed. + (cherry-pick 96a4647fca54031974cd6ad1 later to maint). + + * When autoconf is used, any build on a different commit always ran + "config.status --recheck" even when unnecessary. + (merge 1226504 jn/less-reconfigure later to maint). + + * We have been carrying a translated and long-unmaintained copy of an + old version of the tutorial; removed. + (merge 0a85441 ta/remove-stale-translated-tut later to maint). + + * t4014, t9502 and t0200 tests had various portability issues that + broke on OpenBSD. + (merge 27f6342 jc/maint-test-portability later to maint). + + * t9020 and t3600 tests had various portability issues. + (merge 5a02966 jc/test-portability later to maint). + + * t9200 runs "cvs init" on a directory that already exists, but a + platform can configure this fail for the current user (e.g. you + need to be in the cvsadmin group on NetBSD 6.0). + (merge 8666df0 jc/test-cvs-no-init-in-existing-dir later to maint). + + * t9020 and t9810 had a few non-portable shell script construct. + (merge 2797914 tb/test-t9020-no-which later to maint). + (merge 6f4e505 tb/test-t9810-no-sed-i later to maint). |
