This immediately - reduces the need to later ask "Have you forgotten to set - core.user?", and we can add more to the template as we gain - more experience. - - * "git stash list -p" used to be almost always a no-op because each - stash entry is represented as a merge commit. It learned to show - the difference between the base commit version and the working tree - version, which is in line with what "git stash show" gives. - - * Sometimes users want to report a bug they experience on their - repository, but they are not at liberty to share the contents of - the repository. "fast-export" was taught an "--anonymize" option - to replace blob contents, names of people, paths and log - messages with bland and simple strings to help them. - - * "git difftool" learned an option to stop feeding paths to the - diff backend when it exits with a non-zero status. - - * "git grep" learned to paint (or not paint) partial matches on - context lines when showing "grep -C<num>" output in color. - - * "log --date=iso" uses a slight variant of the ISO 8601 format that is - more human readable. A new "--date=iso-strict" option gives - datetime output that conforms more strictly. - - * The logic "git prune" uses is more resilient against various corner - cases. - - * A broken reimplementation of Git could write an invalid index that - records both stage #0 and higher-stage entries for the same path. - We now notice and reject such an index, as there is no sensible - fallback (we do not know if the broken tool wanted to resolve and - forgot to remove the higher-stage entries, or if it wanted to unresolve - and forgot to remove the stage #0 entry). - - * The temporary files "git mergetool" uses are renamed to avoid too - many dots in them (e.g. a temporary file for "hello.c" used to be - named e.g. "hello.BASE.4321.c" but now uses underscore instead, - e.g. "hello_BASE_4321.c", to allow us to have multiple variants). - - * The temporary files "git mergetool" uses can be placed in a newly - created temporary directory, instead of the current directory, by - setting the mergetool.writeToTemp configuration variable. - - * "git mergetool" understands "--tool bc" now, as version 4 of - BeyondCompare can be driven the same way as its version 3 and it - feels awkward to say "--tool bc3" to run version 4. - - * The "pre-receive" and "post-receive" hooks are no longer required - to consume their input fully (not following this requirement used - to result in intermittent errors in "git push"). - - * The pretty-format specifier "%d", which expands to " (tagname)" - for a tagged commit, gained a cousin "%D" that just gives the - "tagname" without frills. - - * "git push" learned "--signed" push, that allows a push (i.e. - request to update the refs on the other side to point at a new - history, together with the transmission of necessary objects) to be - signed, so that it can be verified and audited, using the GPG - signature of the person who pushed, that the tips of branches at a - public repository really point the commits the pusher wanted to, - without having to "trust" the server. - - * "git interpret-trailers" is a new filter to programmatically edit - the tail end of the commit log messages, e.g. "Signed-off-by:". - - * "git help everyday" shows the "Everyday Git in 20 commands or so" - document, whose contents have been updated to match more modern - Git practice. - - * On the "git svn" front, work progresses to reduce memory consumption and - to improve handling of mergeinfo. - - -Performance, Internal Implementation, Development Support etc. - - * The API to manipulate the "refs" has been restructured to make it - more transactional, with the eventual goal to allow all-or-none - atomic updates and migrating the storage to something other than - the traditional filesystem based one (e.g. databases). - - * The lockfile API and its users have been cleaned up. - - * We no longer attempt to keep track of individual dependencies to - the header files in the build procedure, relying instead on automated - dependency generation support from modern compilers. - - * In tests, we have been using NOT_{MINGW,CYGWIN} test prerequisites - long before negated prerequisites e.g. !MINGW were invented. - The former has been converted to the latter to avoid confusion. - - * Optimized looking up a remote's configuration in a repository with very many - remotes defined. - - * There are cases where you lock and open to write a file, close it - to show the updated contents to an external processes, and then have - to update the file again while still holding the lock; now the - lockfile API has support for such an access pattern. - - * The API to allocate the structure to keep track of commit - decoration has been updated to make it less cumbersome to use. - - * An in-core caching layer to let us avoid reading the same - configuration files several times has been added. A few commands - have been converted to use this subsystem. - - * Various code paths have been cleaned up and simplified by using - the "strbuf", "starts_with()", and "skip_prefix()" APIs more. - - * A few codepaths that died when large blobs that would not fit in - core are involved in their operation have been taught to punt - instead, by e.g. marking a too-large blob as not to be diffed. - - * A few more code paths in "commit" and "checkout" have been taught - to repopulate the cache-tree in the index, to help speed up later - "write-tree" (used in "commit") and "diff-index --cached" (used in - "status"). - - * A common programming mistake to assign the same short option name - to two separate options is detected by the parse_options() API to help - developers. - - * The code path to write out the packed-refs file has been optimized, - which especially matters in a repository with a large number of - refs. - - * The check to see if a ref $F can be created by making sure no - existing ref has $F/ as its prefix has been optimized, which - especially matters in a repository with a large number of existing - refs. - - * "git fsck" was taught to check the contents of tag objects a bit more. - - * "git hash-object" was taught a "--literally" option to help - debugging. - - * When running a required clean filter, we do not have to mmap the - original before feeding the filter. Instead, stream the file - contents directly to the filter and process its output. - - * The scripts in the test suite can be run with the "-x" option to show - a shell-trace of each command they run. - - * The "run-command" API learned to manage the argv and environment - arrays for child process, alleviating the need for the callers to - allocate and deallocate them. - - * Some people use AsciiDoctor, instead of AsciiDoc, to format our - documentation set; the documentation has been adjusted to be usable - by both, as AsciiDoctor is pickier than AsciiDoc about its input - mark-up. - - -Also contains various documentation updates and code clean-ups. - - -Fixes since v2.1 ----------------- - -Unless otherwise noted, all the fixes since v2.1 in the maintenance -track are contained in this release (see the maintenance releases' -notes for details). - - * "git log --pretty/format=" with an empty format string did not - mean the more obvious "No output whatsoever" but "Use default - format", which was counterintuitive. - - * "git -c section.var command" and "git -c section.var= command" - should pass the configuration value differently (the former should be a - boolean true, the latter should be an empty string). - - * Applying a patch not generated by Git in a subdirectory used to - check for whitespace breakage using the attributes of incorrect - paths. Also whitespace checks were performed even for paths - excluded via the "git apply --exclude=<path>" mechanism. - - * "git bundle create" with a date-range specification was meant to - exclude tags outside the range, but it didn't. - - * "git add x" where x used to be a directory and is now a - symbolic link to a directory misbehaved. - - * The prompt script checked the $GIT_DIR/ref/stash file to see if there - is a stash, which was a no-no. - - * Pack-protocol documentation had a minor typo. - - * "git checkout -m" did not switch to another branch while carrying - the local changes forward when a path was deleted from the index. - - * "git daemon" (with NO_IPV6 build configuration) used to incorrectly - use the hostname even when gethostbyname() reported that the given - hostname is not found. - (merge 107efbe rs/daemon-fixes later to maint). - - * With sufficiently long refnames, "git fast-import" could have - overflowed an on-stack buffer. - - * After "pack-refs --prune" packed refs at the top-level, it failed - to prune them. - - * Progress output from "git gc --auto" was visible in "git fetch -q". - - * We used to pass -1000 to poll(2), expecting it to also mean "no - timeout", which should be spelled as -1. - - * "git rebase" documentation was unclear that it is required to - specify on what <upstream> the rebase is to be done when telling it - to first check out <branch>. - (merge 95c6826 so/rebase-doc later to maint). - - * "git push" over HTTP transport had an artificial limit on the number of - refs that can be pushed, imposed by the command line length. - (merge 26be19b jk/send-pack-many-refspecs later to maint). - - * When receiving an invalid pack stream that records the same object - twice, multiple threads got confused due to a race. - (merge ab791dd jk/index-pack-threading-races later to maint). - - * An attempt to remove the entire tree in the "git fast-import" input - stream caused it to misbehave. - (merge 2668d69 mb/fast-import-delete-root later to maint). - - * Reachability check (used in "git prune" and friends) did not add a - detached HEAD as a starting point to traverse objects still in use. - (merge c40fdd0 mk/reachable-protect-detached-head later to maint). - - * "git config --add section.var val" when section.var already has an - empty-string value used to lose the empty-string value. - (merge c1063be ta/config-add-to-empty-or-true-fix later to maint). - - * "git fsck" failed to report that it found corrupt objects via its - exit status in some cases. - (merge 30d1038 jk/fsck-exit-code-fix later to maint). - - * Use of the "--verbose" option used to break "git branch --merged". - (merge 12994dd jk/maint-branch-verbose-merged later to maint). - - * Some MUAs mangle a line in a message that begins with "From " to - ">From " when writing to a mailbox file, and feeding such an input - to "git am" used to lose such a line. - (merge 85de86a jk/mbox-from-line later to maint). - - * "rev-parse --verify --quiet $name" is meant to quietly exit with a - non-zero status when $name is not a valid object name, but still - gave error messages in some cases. - - * A handful of C source files have been updated to include - "git-compat-util.h" as the first thing, to conform better to our - coding guidelines. - (merge 1c4b660 da/include-compat-util-first-in-c later to maint). - - * The t7004 test, which tried to run Git with small stack space, has been - updated to use a bit larger stack to avoid false breakage on some - platforms. - (merge b9a1907 sk/tag-contains-wo-recursion later to maint). - - * A few documentation pages had example sections marked up not quite - correctly, which passed AsciiDoc but failed with AsciiDoctor. - (merge c30c43c bc/asciidoc-pretty-formats-fix later to maint). - (merge f8a48af bc/asciidoc later to maint). - - * "gitweb" used deprecated CGI::startfrom, which was removed from - CGI.pm as of 4.04; use CGI::start_from instead. - (merge 4750f4b rm/gitweb-start-form later to maint). - - * Newer versions of 'meld' break the auto-detection we use to see if - they are new enough to support the `--output` option. - (merge b12d045 da/mergetool-meld later to maint). - - * "git pack-objects" forgot to disable the codepath to generate the - object reachability bitmap when it needs to split the resulting - pack. - (merge 2113471 jk/pack-objects-no-bitmap-when-splitting later to maint). - - * The code to use cache-tree trusted the on-disk data too much and - fell into an infinite loop upon seeing an incorrectly recorded - index file. - (merge 729dbbd jk/cache-tree-protect-from-broken-libgit2 later to maint). - - * "git fetch" into a repository where branch B was deleted earlier, - back when it had reflog enabled, and then branch B/C is fetched - into it without reflog enabled, which is arguably an unlikely - corner case, unnecessarily failed. - (merge aae828b jk/fetch-reflog-df-conflict later to maint). - - * "git log --first-parent -L..." used to crash. - (merge a8787c5 tm/line-log-first-parent later to maint). |
