There will be no +mechanism to make plain "git add -u" behave like "git add -u .". +Current users of "git add -u" (without a pathspec) should start +training their fingers to explicitly say "git add -u ." +before Git 2.0 comes. A warning is issued when these commands are +run without a pathspec and when you have local changes outside the +current directory, because the behaviour in Git 2.0 will be different +from today's version in such a situation. + +In Git 2.0, "git add <path>" will behave as "git add -A <path>", so +that "git add dir/" will notice paths you removed from the directory +and record the removal.

By setting it to 'auto', you can turn it on only for a + series with two or more patches. + + * The bash completion support (in contrib/) learned that cherry-pick + takes a few more options than it already knew about. + + * "git help" learned "-g" option to show the list of guides just like + list of commands are given with "-a". + + * A triangular "pull from one place, push to another place" workflow + is supported better by new remote.pushdefault (overrides the + "origin" thing) and branch.*.pushremote (overrides the + branch.*.remote) configuration variables. + + * "git status" learned to report that you are in the middle of a + revert session, just like it does for a cherry-pick and a bisect + session. + + * The handling by "git branch --set-upstream-to" against various forms + of erroneous inputs was suboptimal and has been improved. + + * When the interactive access to git-shell is not enabled, it issues + a message meant to help the system administrator to enable it.

Also a bug in "git checkout dir/" + that is started from an unmerged index has been fixed. + + * A few bugfixes to "git rerere" working on corner case merge + conflicts have been applied. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v1.8.2 +------------------ + +Unless otherwise noted, all the fixes since v1.8.2 in the maintenance +track are contained in this release (see release notes to them for +details). + + * Recent versions of File::Temp (used by "git svn") started blowing + up when its tempfile sub is called as a class method; updated the + callsite to call it as a plain vanilla function to fix it. + (merge eafc2dd hb/git-pm-tempfile later to maint). + + * Various subcommands of "git remote" simply ignored extraneous + command line arguments instead of diagnosing them as errors. + + * When receive-pack detects an error in the pack header it received in + order to decide which of unpack-objects or index-pack to run, it + returned without closing the error stream, which led to a hung + sideband thread. + + * Zsh completion forgot that the '%' character used to signal untracked + files needs to be escaped with another '%'. + + * A commit object whose author or committer ident are malformed + crashed some code that trusted that a name, an email and a + timestamp can always be found in it. + + * When "upload-pack" fails while generating a pack in response to + "git fetch" (or "git clone"), the receiving side had + a programming error that triggered the die handler + recursively. + + * "rev-list --stdin" and friends kept bogus pointers into the input + buffer around as human readable object names. This was not a huge + problem but was exposed by a new change that uses these names in + error output. + + * Smart-capable HTTP servers were not restricted via the + GIT_NAMESPACE mechanism when talking with commit-walking clients, + like they are when talking with smart HTTP clients. + (merge 6130f86 jk/http-dumb-namespaces later to maint). + + * "git merge-tree" did not omit a merge result that is identical to + the "our" side in certain cases. + (merge aacecc3 jk/merge-tree-added-identically later to maint). + + * Perl scripts like "git-svn" closed (instead of redirecting to /dev/null) + the standard error stream, which is not a very smart thing to do. + A later open may return file descriptor #2 for an unrelated purpose, and + error reporting code may write into it. + + * "git show-branch" was not prepared to show a very long run of + ancestor operators e.g. foobar^2~2^2^2^2...^2~4 correctly. + + * "git diff --diff-algorithm algo" is also understood as "git diff + --diff-algorithm=algo". + + * The new core.commentchar configuration was not applied in a few + places. + + * "git bundle" erroneously bailed out when parsing a valid bundle + containing a prerequisite commit without a commit message. + + * "git log -S/-G" started paying attention to textconv filter, but + there was no way to disable this.

The message has finally been removed. + + * "git fetch origin master" unlike "git fetch origin" or "git fetch" + did not update "refs/remotes/origin/master"; this was an early + design decision to keep the update of remote tracking branches + predictable, but in practice it turns out that people find it more + convenient to opportunistically update them whenever we have a + chance, and we have been updating them when we run "git push" which + already breaks the original "predictability" anyway. + + * The configuration variable core.checkstat was advertised in the + documentation but the code expected core.statinfo instead. + For now, we accept both core.checkstat and core.statinfo, but the + latter will be removed in the longer term. + + +Performance, Internal Implementation, etc. + + * On Cygwin, we used to use our own lstat(2) emulation that is + allegedly faster than the platform one in codepaths where some of + the information it returns did not matter, but it started to bite + us in a few codepaths where the trick it uses to cheat does show + breakages. This emulation has been removed and we use the native + lstat(2) emulation supplied by Cygwin now. + + * The function attributes extensions are used to catch mistakes in + use of our own variadic functions that use NULL sentinel at the end + (i.e. like execl(3)) and format strings (i.e. like printf(3)). + + * The code to allow configuration data to be read from in-tree blob + objects is in. This may help working in a bare repository and + submodule updates. + + * Fetching between repositories with many refs employed O(n^2) + algorithm to match up the common objects, which has been corrected. + + * The original way to specify remote repository using .git/branches/ + used to have a nifty feature. The code to support the feature was + still in a function but the caller was changed not to call it 5 + years ago, breaking that feature and leaving the supporting code + unreachable. The dead code has been removed. + + * "git pack-refs" that races with new ref creation or deletion have + been susceptible to lossage of refs under right conditions, which + has been tightened up. + + * We read loose and packed references in two steps, but after + deciding to read a loose ref but before actually opening it to read + it, another process racing with us can unlink it, which would cause + us to barf. The codepath has been updated to retry when such a + race is detected, instead of outright failing. + + * Uses of the platform fnmatch(3) function (many places in the code, + matching pathspec, .gitignore and .gitattributes to name a few) + have been replaced with wildmatch, allowing "foo/**/bar" that would + match foo/bar, foo/a/bar, foo/a/b/bar, etc. + + * Memory ownership and lifetime rules for what for-each-ref feeds to + its callbacks have been clarified (in short, "you do not own it, so + make a copy if you want to keep it"). + + * The revision traversal logic to improve culling of irrelevant + parents while traversing a mergy history has been updated. + + * Some leaks in unpack-trees (used in merge, cherry-pick and other + codepaths) have been plugged. + + * The codepath to read from marks files in fast-import/export did not + have to accept anything but 40-hex representation of the object + name. Further, fast-export did not need full in-core object + representation to have parsed wen reading from them. These + codepaths have been optimized by taking advantage of these access + patterns. + + * Object lookup logic, when the object hashtable starts to become + crowded, has been optimized. + + * When TEST_OUTPUT_DIRECTORY setting is used, it was handled somewhat + inconsistently between the test framework and t/Makefile, and logic + to summarize the results looked at a wrong place. + + * "git clone" uses a lighter-weight implementation when making sure + that the history behind refs are complete. + + * Many warnings from sparse source checker in compat/ area has been + squelched. + + * The code to reading and updating packed-refs file has been updated, + correcting corner case bugs. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v1.8.3 +------------------ + +Unless otherwise noted, all the fixes since v1.8.3 in the maintenance +track are contained in this release (see release notes to them for +details). + + * Newer Net::SMTP::SSL module does not want the user programs to use + the default behaviour to let server certificate go without + verification, so by default enable the verification with a + mechanism to turn it off if needed. + (merge 35035bb rr/send-email-ssl-verify later to maint). + + * When "git" is spawned in such a way that any of the low 3 file + descriptors is closed, our first open() may yield file descriptor 2, + and writing error message to it would screw things up in a big way. + (merge a11c396 tr/protect-low-3-fds later to maint). + + * The mailmap mechanism unnecessarily downcased the e-mail addresses + in the output, and also ignored the human name when it is a single + character name. + (merge bd23794 jc/mailmap-case-insensitivity later to maint). + + * In two places we did not check return value (expected to be a file + descriptor) correctly. + (merge a77f106 tr/fd-gotcha-fixes later to maint). + + * Logic to auto-detect character encodings in the commit log message + did not reject overlong and invalid UTF-8 characters. + (merge 81050ac bc/commit-invalid-utf8 later to maint). + + * Pass port number as a separate argument when "send-email" initializes + Net::SMTP, instead of as a part of the hostname, i.e. host:port. + This allows GSSAPI codepath to match with the hostname given. + (merge 1a741bf bc/send-email-use-port-as-separate-param later to maint). + + * "git diff" refused to even show difference when core.safecrlf is + set to true (i.e. error out) and there are offending lines in the + working tree files. + (merge 5430bb2 jc/maint-diff-core-safecrlf later to maint). + + * A test that should have failed but didn't revealed a bug that needs + to be corrected. + (merge 94d75d1 jc/t1512-fix later to maint). + + * An overlong path to a .git directory may have overflown the + temporary path buffer used to create a name for lockfiles. + (merge 2fbd4f9 mh/maint-lockfile-overflow later to maint). + + * Invocations of "git checkout" used internally by "git rebase" were + counted as "checkout", and affected later "git checkout -" to the + the user to an unexpected place. + (merge 3bed291 rr/rebase-checkout-reflog later to maint). + + * The configuration variable column.ui was poorly documented. + (merge 5e62cc1 rr/column-doc later to maint). + + * "git name-rev --refs=tags/v*" were forbidden, which was a bit + inconvenient (you had to give a pattern to match refs fully, like + --refs=refs/tags/v*). + (merge 98c5c4a nk/name-rev-abbreviated-refs later to maint). + + * "git apply" parsed patches that add new files, generated by + programs other than Git, incorrectly.

Versions before Git 2.0, including this +release, will keep ignoring removals, but the users who rely on this +behaviour are encouraged to start using "git add --ignore-removal <path>" +now before 2.0 is released. + + +Updates since v1.8.4 +-------------------- + +Foreign interfaces, subsystems and ports. + + * "git-svn" used with SVN 1.8.0 when talking over https:// connection + dumped core due to a bug in the serf library that SVN uses. Work + it around on our side, even though the SVN side is being fixed. + + * On MacOS X, we detected if the filesystem needs the "pre-composed + unicode strings" workaround, but did not automatically enable it. + Now we do. + + * remote-hg remote helper misbehaved when interacting with a local Hg + repository relative to the home directory, e.g. "clone hg::~/there". + + * imap-send ported to OS X uses Apple's security framework instead of + OpenSSL one. + + * Subversion 1.8.0 that was recently released breaks older subversion + clients coming over http/https in various ways. + + * "git fast-import" treats an empty path given to "ls" as the root of + the tree. + + +UI, Workflows & Features + + * A packfile that stores the same object more than once is broken and + will be rejected by "git index-pack" that is run when receiving + data over the wire. + + * Earlier we started rejecting an attempt to add 0{40} object name to + the index and to tree objects, but it sometimes is necessary to + allow so to be able to use tools like filter-branch to correct such + broken tree objects. "filter-branch" can again be used to to do + so. + + * "git config" did not provide a way to set or access numbers larger + than a native "int" on the platform; it now provides 64-bit signed + integers on all platforms. + + * "git pull --rebase" always chose to do the bog-standard flattening + rebase. You can tell it to run "rebase --preserve-merges" by + setting "pull.rebase" configuration to "preserve". + + * "git push --no-thin" actually disables the "thin pack transfer" + optimization. + + * Magic pathspecs like ":(icase)makefile" that matches both + Makefile and makefile can be used in more places. + + * The "http.*" variables can now be specified per URL that the + configuration applies. For example, + + [http] + sslVerify = true + [http "https://weak.example.com/"] + sslVerify = false + + would flip http.sslVerify off only when talking to that specified + site. + + * "git mv A B" when moving a submodule A has been taught to + relocate its working tree and to adjust the paths in the + .gitmodules file. + + * "git blame" can now take more than one -L option to discover the + origin of multiple blocks of the lines. + + * The http transport clients can optionally ask to save cookies + with http.savecookies configuration variable. + + * "git push" learned a more fine grained control over a blunt + "--force" when requesting a non-fast-forward update with the + "--force-with-lease=<refname>:<expected object name>" option. + + * "git diff --diff-filter=<classes of changes>" can now take + lowercase letters (e.g. "--diff-filter=d") to mean "show + everything but these classes". "git diff-files -q" is now a + deprecated synonym for "git diff-files --diff-filter=d". + + * "git fetch" (hence "git pull" as well) learned to check + "fetch.prune" and "remote.*.prune" configuration variables and + to behave as if the "--prune" command line option was given. + + * "git check-ignore -z" applied the NUL termination to both its input + (with --stdin) and its output, but "git check-attr -z" ignored the + option on the output side. Make both honor -z on the input and + output side the same way. + + * "git whatchanged" may still be used by old timers, but mention of + it in documents meant for new users will only waste readers' time + wonderig what the difference is between it and "git log". Make it + less prominent in the general part of the documentation and explain + that it is merely a "git log" with different default behaviour in + its own document. + + +Performance, Internal Implementation, etc. + + * If a build-time fallback is set to "cat" instead of "less", we + should apply the same "no subprocess or pipe" optimization as we + apply to user-supplied GIT_PAGER=cat. + + * Many commands use --dashed-option as a operation mode selector + (e.g. "git tag --delete") that the user can use at most one + (e.g. "git tag --delete --verify" is a nonsense) and you cannot + negate (e.g. "git tag --no-delete" is a nonsense). parse-options + API learned a new OPT_CMDMODE macro to make it easier to implement + such a set of options. + + * OPT_BOOLEAN() in parse-options API was misdesigned to be "counting + up" but many subcommands expect it to behave as "on/off". Update + them to use OPT_BOOL() which is a proper boolean. + + * "git gc" exits early without doing a double-work when it detects + that another instance of itself is already running. + + * Under memory pressure and/or file descriptor pressure, we used to + close pack windows that are not used and also closed filehandle to + an open but unused packfiles. These are now controlled separately + to better cope with the load. + +Also contains various documentation updates and code clean-ups. + + +Fixes since v1.8.4 +------------------ + +Unless otherwise noted, all the fixes since v1.8.4 in the maintenance +track are contained in this release (see release notes to them for +details). + + * "git cvsserver" computed the permission mode bits incorrectly for + executable files. + (merge 1b48d56 jc/cvsserver-perm-bit-fix later to maint). + + * When send-email comes up with an error message to die with upon + failure to start an SSL session, it tried to read the error string + from a wrong place. + (merge 6cb0c88 bc/send-email-ssl-die-message-fix later to maint). + + * The implementation of "add -i" has a crippling code to work around + ActiveState Perl limitation but it by mistake also triggered on Git + for Windows where MSYS perl is used. + (merge df17e77 js/add-i-mingw later to maint). + + * We made sure that we notice the user-supplied GIT_DIR is actually a + gitfile, but did not do the same when the default ".git" is a + gitfile. + (merge 487a2b7 nd/git-dir-pointing-at-gitfile later to maint). + + * When an object is not found after checking the packfiles and then + loose object directory, read_sha1_file() re-checks the packfiles to + prevent racing with a concurrent repacker; teach the same logic to + has_sha1_file(). + (merge 45e8a74 jk/has-sha1-file-retry-packed later to maint). + + * "git commit --author=$name", when $name is not in the canonical + "A. U. Thor <au.thor@example.xz>" format, looks for a matching name + from existing history, but did not consult mailmap to grab the + preferred author name. + (merge ea16794 ap/commit-author-mailmap later to maint). + + * "git ls-files -k" needs to crawl only the part of the working tree + that may overlap the paths in the index to find killed files, but + shared code with the logic to find all the untracked files, which + made it unnecessarily inefficient. + (merge 680be04 jc/ls-files-killed-optim later to maint). + + * The commit object names in the insn sheet that was prepared at the + beginning of "rebase -i" session can become ambiguous as the + rebasing progresses and the repository gains more commits. Make + sure the internal record is kept with full 40-hex object names. + (merge 75c6976 es/rebase-i-no-abbrev later to maint). + + * "git rebase --preserve-merges" internally used the merge machinery + and as a side effect, left merge summary message in the log, but + when rebasing, there should not be a need for merge summary. + (merge a9f739c rt/rebase-p-no-merge-summary later to maint). + + * A call to xread() was used without a loop around to cope with short + read in the codepath to stream new contents to a pack. + (merge e92527c js/xread-in-full later to maint). + + * "git rebase -i" forgot that the comment character can be + configurable while reading its insn sheet. + (merge 7bca7af es/rebase-i-respect-core-commentchar later to maint). + + * The mailmap support code read past the allocated buffer when the + mailmap file ended with an incomplete line. + (merge f972a16 jk/mailmap-incomplete-line later to maint). + + * We used to send a large request to read(2)/write(2) as a single + system call, which was bad from the latency point of view when + the operation needs to be killed, and also triggered an error on + broken 64-bit systems that refuse to take more than 2GB read or + write in one go. + (merge a487916 sp/clip-read-write-to-8mb later to maint). + + * "git fetch" that auto-followed tags incorrectly reused the + connection with Git-aware transport helper (like the sample "ext::" + helper shipped with Git). + (merge 0f73f8b jc/transport-do-not-use-connect-twice-in-fetch later to maint). + + * "git log --full-diff -- <pathspec>" showed a huge diff for paths + outside the given <pathspec> for each commit, instead of showing + the change relative to the parent of the commit. "git reflog -p" + had a similar problem. + (merge 838f9a1 tr/log-full-diff-keep-true-parents later to maint). + + * Setting submodule.*.path configuration variable to true (without + giving "= value") caused Git to segfault. + (merge 4b05440 jl/some-submodule-config-are-not-boolean later to maint). + + * "git rebase -i" (there could be others, as the root cause is pretty + generic) fed a random, data dependeant string to 'echo' and + expects it to come out literally, corrupting its error message. + (merge 89b0230 mm/no-shell-escape-in-die-message later to maint). + + * Some people still use rather old versions of bash, which cannot + grok some constructs like 'printf -v varname' the prompt and + completion code started to use recently. + (merge a44aa69 bc/completion-for-bash-3.0 later to maint). + + * Code to read configuration from a blob object did not compile on + platforms with fgetc() etc. implemented as macros. + (merge 49d6cfa hv/config-from-blob later to maint-1.8.3). + + * The recent "short-cut clone connectivity check" topic broke a + shallow repository when a fetch operation tries to auto-follow tags. + (merge 6da8bdc nd/fetch-pack-shallow-fix later to maint-1.8.3). |
