GIT v1.6.1 Release Notes ======================== Updates since v1.6.0 -------------------- When some commands (e.g. "git log", "git diff") spawn pager internally, we used to make the pager the parent process of the git command that produces output. This meant that the exit status of the whole thing comes from the pager, not the underlying git command. We swapped the order of the processes around and you will see the exit code from the command from now on. (subsystems) * gitk can call out to git-gui to view "git blame" output; git-gui in turn can run gitk from its blame view. * Various git-gui updates including updated translations. * Various gitweb updates from repo.or.cz installation. (portability) * A few test scripts used nonportable "grep" that did not work well on some platforms, e.g. Solaris. * Sample pre-auto-gc script has OS X support. (performance) * The underlying diff machinery to produce textual output has been optimized, which would result in faster "git blame" processing. * Most of the test scripts (but not the ones that try to run servers) can be run in parallel. * Bash completion of refnames in a repository with massive number of refs has been optimized. * Cygwin port uses native stat/lstat implementations when applicable, which leads to improved performance. * "git push" pays attention to alternate repositories to avoid sending unnecessary objects. * "git svn" can rebuild an out-of-date rev_map file. (usability, bells and whistles) * When you mistype a command name, git helpfully suggests what it guesses you might have meant to say. help.autocorrect configuration can be set to a non-zero value to accept the suggestion when git can uniquely guess. * "git add -N path..." adds the named paths as an empty blob, so that subsequent "git diff" will show a diff as if they are creation events. * "git apply" learned --include=paths option, similar to the existing --exclude=paths option. * "git bisect" is careful about a user mistake and suggests testing of merge base first when good is not a strict ancestor of bad. * "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding by default. * "git check-attr --stdin" can check attributes for multiple paths. * "git checkout --track origin/hack" used to be a syntax error. It now DWIMs to create a corresponding local branch "hack", i.e. acts as if you said "git checkout --track -b hack origin/hack". * "git checkout --ours/--theirs" can be used to check out one side of a conflicting merge during conflict resolution. * "git checkout -m" can be used to recreate the initial conflicted state during conflict resolution. * "git cherry-pick" can also utilize rerere for conflict resolution. * "git clone" learned to be verbose with -v * "git commit --author=$name" can look up author name from existing commits. * output from "git commit" has been reworded in a more concise and yet more informative way. * "git count-objects" reports the on-disk footprint for packfiles and their corresponding idx files. * "git daemon" learned --max-connections= option. * "git daemon" exports REMOTE_ADDR to record client address, so that spawned programs can act differently on it. * "git describe --tags" favours closer lightweight tags than farther annotated tags now. * "git diff" learned to mimic --suppress-blank-empty from GNU diff via a configuration option. * "git diff" learned to put more sensible hunk headers for Python, HTML and ObjC contents. * "git diff" learned to vary the a/ vs b/ prefix depending on what are being compared, controlled by diff.mnemonicprefix configuration. * "git diff" learned --dirstat-by-file to count changed files, not number of lines, when summarizing the global picture. * "git diff" hunk header pattern for ObjC has been added. * a "textconv" filter that makes binary files textual form for human consumption can be specified as an attribute for paths; "git diff" learnt to make use of it. * "git for-each-ref" learned "refname:short" token that gives an unambiguously abbreviated refname. * Auto-numbering of the subject lines is the default for "git format-patch" now. * "git grep" learned to accept -z similar to GNU grep. * "git help" learned to use GIT_MAN_VIEWER environment variable before using "man" program. * "git imap-send" can optionally talk SSL. * "git index-pack" is more careful against disk corruption while completing a thin pack. * "git log --check" and "git log --exit-code" passes their underlying diff status with their exit status code. * "git log" learned --simplify-merges, a milder variant of --full-history; "gitk --simplify-merges" is easier to view than with --full-history. * "git log --pretty=format:" learned "%d" format element that inserts names of tags that point at the commit. * "git merge --squash" and "git merge --no-ff" into an unborn branch are noticed as user errors. * "git merge -s $strategy" can use a custom built strategy if you have a command "git-merge-$strategy" on your $PATH. * "git push" can be told to reject deletion of refs with receive.denyDeletes configuration. * "git rebase" honours pre-rebase hook; use --no-verify to bypass it. * "git rebase -p" uses interactive rebase machinery now to preserve the merges. * "git reflog expire branch" can be used in place of "git reflog expire refs/heads/branch". * "git remote show $remote" lists remote branches one-per-line now. * when giving up resolving a conflicted merge, "git reset --hard" failed to remove new paths from the working tree. [cherry-pick to 'maint'?] * "git submodule foreach" subcommand allows you to iterate over checked out submodules. * "git submodule sync" subcommands allows you to update the origin URL recorded in submodule directories from the toplevel .gitmodules file. * "git svn branch" can create new branches on the other end. * "gitweb" can use more saner PATH_INFO based URL. (internal) * "git hash-object" learned to lie about the path being hashed, so that correct gitattributes processing can be done while hashing contents stored in a temporary file. * various callers of git-merge-recursive avoid forking it as an external process. * Git class defined in "Git.pm" can be subclasses a bit more easily. * We used to link GNU regex library as a compatibility layer for some platforms, but it turns out it is not necessary on most of them. * Some path handling routines used fixed number of buffers used alternately but depending on the call depth, this arrangement led to hard to track bugs. This issue is being addressed. Fixes since v1.6.0 ------------------ All of the fixes in v1.6.0.X maintenance series are included in this release, unless otherwise noted. * "git add" and "git update-index" incorrectly allowed adding S/F when S is a tracked symlink that points at a directory D that has a path F in it (we still need to fix a similar nonsense when S is a submodule and F is a path in it). * "git diff --stdin" used to take two trees on a line and compared them, but we dropped support for such a use case long time ago. This has been resurrected. * Giving 3 or more tree-ish to "git diff" is supposed to show the combined diff from second and subsequent trees to the first one. b75271d ("git diff {3,}": do not reverse order of arguments, 2008-10-10) needs to be cherry-picked to 'maint'. * "git filter-branch" failed to rewrite a tag name with slashes in it. * "git push --tags --all $there" failed with generic usage message without telling saying these two options are incompatible. * "git log --author/--committer" match used to potentially match the timestamp part, exposing internal implementation detail. Also these did not work with --fixed-strings match at all. -- exec >/var/tmp/1 O=v1.6.0.3-639-ga1a846a echo O=$(git describe master) git shortlog --no-merges $O..master ^maint
