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. + +* Updates to emacs bindings. + +(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. + +* Makefile has support for (ancient) FreeBSD 4.9. + +(performance) + +* Many operations that are lstat(3) heavy can be told to pre-execute + necessary lstat(3) in parallel before their main operations, which + potentially gives much improved performance for cold-cache cases or in + environments with weak metadata caching (e.g. NFS). + +* 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 + +* "git svn" can rebuild an out-of-date rev_map file.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. + +* The packfile machinery hopefully is more robust when dealing with + corrupt packs if redundant objects involved in the corruption are + available elsewhere. + +* "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 add" gained a built-in synonym for people who want to say "stage + changes" instead of "add contents to the staging area" which amounts + to the same thing. + +* "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 bisect skip" can take a range of commits. + +* "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" learned "textconv" filters --- a binary or hard-to-read + contents can be munged into human readable form and the difference + between the results of the conversion can be viewed (obviously this + cannot produce a patch that can be applied, so this is disabled in + format-patch among other things). + +* "--cached" option to "git diff has an easier to remember synonym "--staged", + to ask "what is the difference between the given commit and the + contents staged in the index?" + +* "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" learned "--source" to show what ref each commit was reached + from. + +* "git log" also learned "--simplify-by-decoration" to show the + birds-eye-view of the topology of the 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 pull" (and "git fetch") can be told to operate "-v"erbosely or + "-q"uietly. + +* "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. + +* "git send-email" can be given revision range instead of files and + maildirs on the command line, and automatically runs format-patch to + generate patches for the given revision range. + +* "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. + +* Porcelains implemented as shell scripts were utterly confused when you + entered to a subdirectory of a work tree from sideways, following a + symbolic link (this may need to be backported to older releases later). + +* Tracking symbolic links would work better on filesystems whose lstat() + returns incorrect st_size value for them. + +* "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 am" after stopping at a broken patch lost --whitespace, -C, -p and + --3way options given from the command line initially. + +* "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. + +* "git filter-branch" failed to rewrite a tag name with slashes in it. + +* "git http-push" did not understand URI scheme other than opaquelocktoken + when acquiring a lock from the server (this may need to be backported to + older releases later). + +* After "git rebase -p" stopped with conflicts while replaying a merge, + "git rebase --continue" did not work (may need to be backported to older + releases). + +* "git revert" records relative to which parent a revert was made when + reverting a merge. Together with new documentation that explains issues + around reverting a merge and merging from the updated branch later, this + hopefully will reduce user confusion (this may need to be backported to + older releases later). + +* "git rm --cached" used to allow an empty blob that was added earlier to + be removed without --force, even when the file in the work tree has + since been modified. + +* "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. + +* "gitweb" did not mark non-ASCII characters imported from external HTML fragments + correctly. -- cgit 1.4.1
