These are not meant to be parsed by scripts, but -users still may want to be aware of the changes: - - * The output from "git log --decorate" (and, more generally, the "%d" - format specifier used in the "--format=<string>" parameter to the - "git log" family of commands) has changed. It used to list "HEAD" - just like other branches; e.g., - - $ git log --decorate -1 master - commit bdb0f6788fa5e3cacc4315e9ff318a27b2676ff4 (HEAD, master) - ... - - This release changes the output slightly when HEAD refers to a - branch whose name is also shown in the output. The above is now - shown as: - - $ git log --decorate -1 master - commit bdb0f6788fa5e3cacc4315e9ff318a27b2676ff4 (HEAD -> master) - ... - - * The phrasing "git branch" uses to describe a detached HEAD has been - updated to agree with the phrasing used by "git status": - - - When HEAD is at the same commit as when it was originally - detached, they now both show "detached at <commit object name>". - - - When HEAD has moved since it was originally detached, they now - both show "detached from <commit object name>". - - Previously, "git branch" always used "from". - - -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 the - CURLOPT_PROXYAUTH feature, which did not exist in older versions of - the library. - - * We now detect number of CPUs on older BSD-derived systems. - - * Portability fixes and workarounds for shell scripts have been added - to help BSD-derived systems. - - -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 an "--atomic" option that makes a push - that updates more than one ref an "all-or-none" affair. - - * Extending the "push to deploy" feature that was added in 2.3, the - behaviour of "git push" when updating the branch that is checked - out can now be tweaked by a "push-to-checkout" hook. - - * HTTP-based transports now send Accept-Language when making - requests. The languages to accept are inferred from environment - variables on the client side (LANGUAGE, etc). - - * "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. - - * When "git apply --whitespace=fix" fixed whitespace errors in the - common context lines, the command reports that it did so. - - * "git status" now allows the "-v" option to be given twice, in which - case it also shows the differences in the working tree that are not - staged to be committed. - - * "git cherry-pick" used to clean up the log message even when it is - merely replaying an existing commit. It now replays the message - verbatim unless you are editing the message of the resulting - commit. - - * "git archive" can now be told to set the 'text' attribute in the - resulting zip archive. - - * Output from "git log --decorate" now distinguishes between a - detached HEAD vs. a HEAD that points at a branch. - - This is a potentially backward-incompatible change; see above for - more information. - - * When HEAD was detached when at commit xyz and hasn't been moved - since it was detached, "git status" would report "detached at xyz" - whereas "git branch" would report "detached from xyz". Now the - output of "git branch" agrees with that of "git status". - - This is a potentially backward-incompatible change; see above for - more information. - - * "git -C '' subcmd" now works in the current directory (analogously - to "cd ''") rather than dying with an error message. - (merge 6a536e2 kn/git-cd-to-empty later to maint). - - * The versionsort.prereleaseSuffix configuration variable can be used - to specify that, for example, v1.0-pre1 comes before v1.0. - - * A new "push.followTags" configuration turns the "--follow-tags" - option on by default for the "git push" command. - - * "git log --graph --no-walk A B..." is a nonsensical combination of - options: "--no-walk" requests discrete points in the history, while - "--graph" asks to draw connections between these discrete points. - Forbid the use of these options together. - - * "git rev-list --bisect --first-parent" does not work (yet) and can - even cause SEGV; forbid it. "git log --bisect --first-parent" would - not be useful until "git bisect --first-parent" materializes, so - also forbid it for now. - - -Performance, Internal Implementation, Development Support etc. - - * Slightly change the implementation of the N_() macro to help us - detect mistakes. - - * Restructure the implementation of "reflog expire" to fit better - with the recently updated reference API. - - * The transport-helper did not pass 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 - of the chance to honor the wish of the end-users better. - - * The tests that wanted to see that a file becomes unreadable after - running "chmod a-r file", and the tests that wanted to make sure - that they are not run as root, used "can we write into the / - directory?" as a cheap substitute. But on some platforms that is - not a good heuristic. The tests and their prerequisites have been - updated to check what they really require. - (merge f400e51 jk/sanity later to maint). - - * Various issues around "reflog expire", e.g. using --updateref when - expiring a reflog for a symbolic reference, have been corrected - and/or made saner. - - * The documentation for the strbuf API had been split between the API - documentation and the header file. Consolidate the documentation in - strbuf.h. - - * The error handling functions and conventions are now documented in - the API manual (in api-error-handling.txt). - - * Optimize gitattribute 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). - - * Simplify the ref transaction API for verifying that "the ref should - be pointing at this object". - - * Simplify the code in "git daemon" that parses out and holds - hostnames used in request interpolation. - - * Restructure the "git push" codepath to make it easier to add new - configuration bits. - - * The run-command interface made it easy to make a pipe for us to - read from a process, wait for the process to finish, and then - attempt to read its output. But this pattern can lead to deadlock. - So introduce a helper to do this correctly (i.e., first read, and - then wait the process to finish) and also add code to prevent such - abuse in the run-command helper. - - * People often forget to chain the commands in their test together - with &&, letting a failure from an earlier command in the test go - unnoticed. 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). |
