|  | GIT v1.5.1 Release Notes | 
|  | ======================== | 
|  |  | 
|  | Updates since v1.5.0 | 
|  | -------------------- | 
|  |  | 
|  | * Deprecated commands and options. | 
|  |  | 
|  | - git-diff-stages and git-resolve have been removed. | 
|  |  | 
|  | * New commands and options. | 
|  |  | 
|  | - "git log" and friends take --reverse, which instructs them | 
|  | to give their output in the order opposite from their usual. | 
|  | They typically output from new to old, but with this option | 
|  | their output would read from old to new. "git shortlog" | 
|  | usually lists older commits first, but with this option, | 
|  | they are shown from new to old. | 
|  |  | 
|  | - "git log --pretty=format:<string>" to allow more flexible | 
|  | custom log output. | 
|  |  | 
|  | - "git diff" learned --ignore-space-at-eol. This is a weaker | 
|  | form of --ignore-space-change. | 
|  |  | 
|  | - "git diff --no-index pathA pathB" can be used as diff | 
|  | replacement with git specific enhancements. | 
|  |  | 
|  | - "git diff --no-index" can read from '-' (standard input). | 
|  |  | 
|  | - "git diff" also learned --exit-code to exit with non-zero | 
|  | status when it found differences. In the future we might | 
|  | want to make this the default but that would be a rather big | 
|  | backward incompatible change; it will stay as an option for | 
|  | now. | 
|  |  | 
|  | - "git diff --quiet" is --exit-code with output turned off, | 
|  | meant for scripted use to quickly determine if there is any | 
|  | tree-level difference. | 
|  |  | 
|  | - Textual patch generation with "git diff" without -w/-b | 
|  | option has been significantly optimized. "git blame" got | 
|  | faster because of the same change. | 
|  |  | 
|  | - "git log" and "git rev-list" has been optimized | 
|  | significantly when they are used with pathspecs. | 
|  |  | 
|  | - "git branch --track" can be used to set up configuration | 
|  | variables to help it easier to base your work on branches | 
|  | you track from a remote site. | 
|  |  | 
|  | - "git format-patch --attach" now emits attachments. Use | 
|  | --inline to get an inlined multipart/mixed. | 
|  |  | 
|  | - "git name-rev" learned --refs=<pattern>, to limit the tags | 
|  | used for naming the given revisions only to the ones | 
|  | matching the given pattern. | 
|  |  | 
|  | - "git remote update" is to run "git fetch" for defined remotes | 
|  | to update tracking branches. | 
|  |  | 
|  | - "git cvsimport" can now take '-d' to talk with a CVS | 
|  | repository different from what are recorded in CVS/Root | 
|  | (overriding it with environment CVSROOT does not work). | 
|  |  | 
|  | - "git bundle" can help sneaker-netting your changes between | 
|  | repositories. | 
|  |  | 
|  | - "git mergetool" can help 3-way file-level conflict | 
|  | resolution with your favorite graphical merge tools. | 
|  |  | 
|  | - A new configuration "core.symlinks" can be used to disable | 
|  | symlinks on filesystems that do not support them; they are | 
|  | checked out as regular files instead. | 
|  |  | 
|  | - You can name a commit object with its first line of the | 
|  | message. The syntax to use is ':/message text'. E.g. | 
|  |  | 
|  | $ git show ":/object name: introduce ':/<oneline prefix>' notation" | 
|  |  | 
|  | means the same thing as: | 
|  |  | 
|  | $ git show 28a4d940443806412effa246ecc7768a21553ec7 | 
|  |  | 
|  | - "git bisect" learned a new command "run" that takes a script | 
|  | to run after each revision is checked out to determine if it | 
|  | is good or bad, to automate the bisection process. | 
|  |  | 
|  | - "git log" family learned a new traversal option --first-parent, | 
|  | which does what the name suggests. | 
|  |  | 
|  |  | 
|  | * Updated behavior of existing commands. | 
|  |  | 
|  | - "git-merge-recursive" used to barf when there are more than | 
|  | one common ancestors for the merge, and merging them had a | 
|  | rename/rename conflict. This has been fixed. | 
|  |  | 
|  | - "git fsck" does not barf on corrupt loose objects. | 
|  |  | 
|  | - "git rm" does not remove newly added files without -f. | 
|  |  | 
|  | - "git archimport" allows remapping when coming up with git | 
|  | branch names from arch names. | 
|  |  | 
|  | - git-svn got almost a rewrite. | 
|  |  | 
|  | - core.autocrlf configuration, when set to 'true', makes git | 
|  | to convert CRLF at the end of lines in text files to LF when | 
|  | reading from the filesystem, and convert in reverse when | 
|  | writing to the filesystem. The variable can be set to | 
|  | 'input', in which case the conversion happens only while | 
|  | reading from the filesystem but files are written out with | 
|  | LF at the end of lines. Currently, which paths to consider | 
|  | 'text' (i.e. be subjected to the autocrlf mechanism) is | 
|  | decided purely based on the contents, but the plan is to | 
|  | allow users to explicitly override this heuristic based on | 
|  | paths. | 
|  |  | 
|  | - The behavior of 'git-apply', when run in a subdirectory, | 
|  | without --index nor --cached were inconsistent with that of | 
|  | the command with these options. This was fixed to match the | 
|  | behavior with --index. A patch that is meant to be applied | 
|  | with -p1 from the toplevel of the project tree can be | 
|  | applied with any custom -p<n> option. A patch that is not | 
|  | relative to the toplevel needs to be applied with -p<n> | 
|  | option with or without --index (or --cached). | 
|  |  | 
|  | - "git diff" outputs a trailing HT when pathnames have embedded | 
|  | SP on +++/--- header lines, in order to help "GNU patch" to | 
|  | parse its output. "git apply" was already updated to accept | 
|  | this modified output format since ce74618d (Sep 22, 2006). | 
|  |  | 
|  | - "git cvsserver" runs hooks/update and honors its exit status. | 
|  |  | 
|  | - "git cvsserver" can be told to send everything with -kb. | 
|  |  | 
|  | - "git diff --check" also honors the --color output option. | 
|  |  | 
|  | - "git name-rev" used to stress the fact that a ref is a tag too | 
|  | much, by saying something like "v1.2.3^0~22". It now says | 
|  | "v1.2.3~22" in such a case (it still says "v1.2.3^0" if it does | 
|  | not talk about an ancestor of the commit that is tagged, which | 
|  | makes sense). | 
|  |  | 
|  | - "git rev-list --boundary" now shows boundary markers for the | 
|  | commits omitted by --max-age and --max-count condition. | 
|  |  | 
|  | - The configuration mechanism now reads $(prefix)/etc/gitconfig. | 
|  |  | 
|  | - "git apply --verbose" shows what preimage lines were wanted | 
|  | when it couldn't find them. | 
|  |  | 
|  | - "git status" in a read-only repository got a bit saner. | 
|  |  | 
|  | - "git fetch" (hence "git clone" and "git pull") are less | 
|  | noisy when the output does not go to tty. | 
|  |  | 
|  | - "git fetch" between repositories with many refs were slow | 
|  | even when there are not many changes that needed | 
|  | transferring. This has been sped up by partially rewriting | 
|  | the heaviest parts in C. | 
|  |  | 
|  | - "git mailinfo" which splits an e-mail into a patch and the | 
|  | meta-information was rewritten, thanks to Don Zickus. It | 
|  | handles nested multipart better. The command was broken for | 
|  | a brief period on 'master' branch since 1.5.0 but the | 
|  | breakage is fixed now. | 
|  |  | 
|  | - send-email learned configurable bcc and chain-reply-to. | 
|  |  | 
|  | - "git remote show $remote" also talks about branches that | 
|  | would be pushed if you run "git push remote". | 
|  |  | 
|  | - Using objects from packs is now seriously optimized by clever | 
|  | use of a cache. This should be most noticeable in git-log | 
|  | family of commands that involve reading many tree objects. | 
|  | In addition, traversing revisions while filtering changes | 
|  | with pathspecs is made faster by terminating the comparison | 
|  | between the trees as early as possible. | 
|  |  | 
|  |  | 
|  | * Hooks | 
|  |  | 
|  | - The part to send out notification e-mails was removed from | 
|  | the sample update hook, as it was not an appropriate place | 
|  | to do so. The proper place to do this is the new post-receive | 
|  | hook. An example hook has been added to contrib/hooks/. | 
|  |  | 
|  |  | 
|  | * Others | 
|  |  | 
|  | - git-revert, git-gc and git-cherry-pick are now built-ins. | 
|  |  | 
|  | Fixes since v1.5.0 | 
|  | ------------------ | 
|  |  | 
|  | These are all in v1.5.0.x series. | 
|  |  | 
|  | * Documentation updates | 
|  |  | 
|  | - Clarifications and corrections to 1.5.0 release notes. | 
|  |  | 
|  | - The main documentation did not link to git-remote documentation. | 
|  |  | 
|  | - Clarified introductory text of git-rebase documentation. | 
|  |  | 
|  | - Converted remaining mentions of update-index on Porcelain | 
|  | documents to git-add/git-rm. | 
|  |  | 
|  | - Some i18n.* configuration variables were incorrectly | 
|  | described as core.*; fixed. | 
|  |  | 
|  | - added and clarified core.bare, core.legacyheaders configurations. | 
|  |  | 
|  | - updated "git-clone --depth" documentation. | 
|  |  | 
|  | - user-manual updates. | 
|  |  | 
|  | - Options to 'git remote add' were described insufficiently. | 
|  |  | 
|  | - Configuration format.suffix was not documented. | 
|  |  | 
|  | - Other formatting and spelling fixes. | 
|  |  | 
|  | - user-manual has better cross references. | 
|  |  | 
|  | - gitweb installation/deployment procedure is now documented. | 
|  |  | 
|  |  | 
|  | * Bugfixes | 
|  |  | 
|  | - git-upload-pack closes unused pipe ends; earlier this caused | 
|  | many zombies to hang around. | 
|  |  | 
|  | - git-rerere was recording the contents of earlier hunks | 
|  | duplicated in later hunks. This prevented resolving the same | 
|  | conflict when performing the same merge the other way around. | 
|  |  | 
|  | - git-add and git-update-index on a filesystem on which | 
|  | executable bits are unreliable incorrectly reused st_mode | 
|  | bits even when the path changed between symlink and regular | 
|  | file. | 
|  |  | 
|  | - git-daemon marks the listening sockets with FD_CLOEXEC so | 
|  | that it won't be leaked into the children. | 
|  |  | 
|  | - segfault from git-blame when the mandatory pathname | 
|  | parameter was missing was fixed; usage() message is given | 
|  | instead. | 
|  |  | 
|  | - git-rev-list did not read $GIT_DIR/config file, which means | 
|  | that did not honor i18n.logoutputencoding correctly. | 
|  |  | 
|  | - Automated merge conflict handling when changes to symbolic | 
|  | links conflicted were completely broken. The merge-resolve | 
|  | strategy created a regular file with conflict markers in it | 
|  | in place of the symbolic link. The default strategy, | 
|  | merge-recursive was even more broken. It removed the path | 
|  | that was pointed at by the symbolic link. Both of these | 
|  | problems have been fixed. | 
|  |  | 
|  | - 'git diff maint master next' did not correctly give combined | 
|  | diff across three trees. | 
|  |  | 
|  | - 'git fast-import' portability fix for Solaris. | 
|  |  | 
|  | - 'git show-ref --verify' without arguments did not error out | 
|  | but segfaulted. | 
|  |  | 
|  | - 'git diff :tracked-file `pwd`/an-untracked-file' gave an extra | 
|  | slashes after a/ and b/. | 
|  |  | 
|  | - 'git format-patch' produced too long filenames if the commit | 
|  | message had too long line at the beginning. | 
|  |  | 
|  | - Running 'make all' and then without changing anything | 
|  | running 'make install' still rebuilt some files. This | 
|  | was inconvenient when building as yourself and then | 
|  | installing as root (especially problematic when the source | 
|  | directory is on NFS and root is mapped to nobody). | 
|  |  | 
|  | - 'git-rerere' failed to deal with two unconflicted paths that | 
|  | sorted next to each other. | 
|  |  | 
|  | - 'git-rerere' attempted to open(2) a symlink and failed if | 
|  | there was a conflict. Since a conflicting change to a | 
|  | symlink would not benefit from rerere anyway, the command | 
|  | now ignores conflicting changes to symlinks. | 
|  |  | 
|  | - 'git-repack' did not like to pass more than 64 arguments | 
|  | internally to underlying 'rev-list' logic, which made it | 
|  | impossible to repack after accumulating many (small) packs | 
|  | in the repository. | 
|  |  | 
|  | - 'git-diff' to review the combined diff during a conflicted | 
|  | merge were not reading the working tree version correctly | 
|  | when changes to a symbolic link conflicted. It should have | 
|  | read the data using readlink(2) but read from the regular | 
|  | file the symbolic link pointed at. | 
|  |  | 
|  | - 'git-remote' did not like period in a remote's name. | 
|  |  | 
|  | - 'git.el' honors the commit coding system from the configuration. | 
|  |  | 
|  | - 'blameview' in contrib/ correctly digs deeper when a line is | 
|  | clicked. | 
|  |  | 
|  | - 'http-push' correctly makes sure the remote side has leading | 
|  | path. Earlier it started in the middle of the path, and | 
|  | incorrectly. | 
|  |  | 
|  | - 'git-merge' did not exit with non-zero status when the | 
|  | working tree was dirty and cannot fast forward. It does | 
|  | now. | 
|  |  | 
|  | - 'cvsexportcommit' does not lose yet-to-be-used message file. | 
|  |  | 
|  | - int-vs-size_t typefix when running combined diff on files | 
|  | over 2GB long. | 
|  |  | 
|  | - 'git apply --whitespace=strip' should not touch unmodified | 
|  | lines. | 
|  |  | 
|  | - 'git-mailinfo' choke when a logical header line was too long. | 
|  |  | 
|  | - 'git show A..B' did not error out. Negative ref ("not A" in | 
|  | this example) does not make sense for the purpose of the | 
|  | command, so now it errors out. | 
|  |  | 
|  | - 'git fmt-merge-msg --file' without file parameter did not | 
|  | correctly error out. | 
|  |  | 
|  | - 'git archimport' barfed upon encountering a commit without | 
|  | summary. | 
|  |  | 
|  | - 'git index-pack' did not protect itself from getting a short | 
|  | read out of pread(2). | 
|  |  | 
|  | - 'git http-push' had a few buffer overruns. | 
|  |  | 
|  | - Build dependency fixes to rebuild fetch.o when other headers | 
|  | change. | 
|  |  | 
|  | - git.el does not add duplicate sign-off lines. | 
|  |  | 
|  | - git-commit shows the full stat of the resulting commit, not | 
|  | just about the files in the current directory, when run from | 
|  | a subdirectory. | 
|  |  | 
|  | - "git-checkout -m '@{8 hours ago}'" had a funny failure from | 
|  | eval; fixed. | 
|  |  | 
|  | - git-merge (hence git-pull) did not refuse fast-forwarding | 
|  | when the working tree had local changes that would have | 
|  | conflicted with it. | 
|  |  | 
|  | - a handful small fixes to gitweb. | 
|  |  | 
|  | - build procedure for user-manual is fixed not to require locally | 
|  | installed stylesheets. | 
|  |  | 
|  | - "git commit $paths" on paths whose earlier contents were | 
|  | already updated in the index were failing out. | 
|  |  | 
|  |  | 
|  | * Tweaks | 
|  |  | 
|  | - sliding mmap() inefficiently mmaped the same region of a | 
|  | packfile with an access pattern that used objects in the | 
|  | reverse order. This has been made more efficient. |
