In such + a case, a realpath of "$dir" is compared with the real path of the + current repository to determine if the contents from the named path + should be included. + + * Make the "indent" heuristics the default in "diff" and diff.indentHeuristics + configuration variable an escape hatch for those who do no want it. + + * Many commands learned to pay attention to submodule.recurse + configuration. + + * The convention for a command line is to follow "git cmdname + --options" with revisions followed by an optional "--" + disambiguator and then finally pathspecs. When "--" is not there, + we make sure early ones are all interpretable as revs (and do not + look like paths) and later ones are the other way around. A + pathspec with "magic" (e.g. ":/p/a/t/h" that matches p/a/t/h from + the top-level of the working tree, no matter what subdirectory you + are working from) are conservatively judged as "not a path", which + required disambiguation more often. The command line parser + learned to say "it's a pathspec" a bit more often when the syntax + looks like so. + + * Update "perl-compatible regular expression" support to enable JIT + and also allow linking with the newer PCRE v2 library. + + * "filter-branch" learned a pseudo filter "--setup" that can be used + to define common functions/variables that can be used by other + filters. + + * Using "git add d/i/r" when d/i/r is the top of the working tree of + a separate repository would create a gitlink in the index, which + would appear as a not-quite-initialized submodule to others. We + learned to give warnings when this happens. + + * "git status" learned to optionally give how many stash entries the + user has in its output. + + * "git status" has long shown essentially the same message as "git + commit"; the message it gives while preparing for the root commit, + i.e. "Initial commit", was hard to understand for some new users. + Now it says "No commits yet" to stress more on the current status + (rather than the commit the user is preparing for, which is more in + line with the focus of "git commit"). + + * "git send-email" learned to overcome some SMTP server limitation + that does not allow many pieces of e-mails to be sent over a single + session. + + * An old message shown in the commit log template was removed, as it + has outlived its usefulness. + + * "git pull --rebase --recurse-submodules" learns to rebase the + branch in the submodules to an updated base. + + +Performance, Internal Implementation, Development Support etc. + + * The default packed-git limit value has been raised on larger + platforms to save "git fetch" from a (recoverable) failure while + "gc" is running in parallel. + + * Code to update the cache-tree has been tightened so that we won't + accidentally write out any 0{40} entry in the tree object. + + * Attempt to allow us notice "fishy" situation where we fail to + remove the temporary directory used during the test. + + * Travis CI gained a task to format the documentation with both + AsciiDoc and AsciiDoctor. + + * Some platforms have ulong that is smaller than time_t, and our + historical use of ulong for timestamp would mean they cannot + represent some timestamp that the platform allows. Invent a + separate and dedicated timestamp_t (so that we can distingiuish + timestamps and a vanilla ulongs, which along is already a good + move), and then declare uintmax_t is the type to be used as the + timestamp_t. + + * We can trigger Windows auto-build tester (credits: Dscho & + Microsoft) from our existing Travis CI tester now. + + * Conversion from uchar[20] to struct object_id continues. + + * Simplify parse_pathspec() codepath and stop it from looking at the + default in-core index. + + * Add perf-test for wildmatch. + + * Code from "conversion using external process" codepath has been + extracted to a separate sub-process.[ch] module. + + * When "git checkout", "git merge", etc. manipulates the in-core + index, various pieces of information in the index extensions are + discarded from the original state, as it is usually not the case + that they are kept up-to-date and in-sync with the operation on the + main index. The untracked cache extension is copied across these + operations now, which would speed up "git status" (as long as the + cache is properly invalidated). + + * The internal implementation of "git grep" has seen some clean-up. + + * Update the C style recommendation for notes for translators, as + recent versions of gettext tools can work with our style of + multi-line comments. + + * The implementation of "ref" API around the "packed refs" have been + cleaned up, in preparation for further changes. + + * The internal logic used in "git blame" has been libified to make it + easier to use by cgit. + + * Our code often opens a path to an optional file, to work on its + contents when we can successfully open it. We can ignore a failure + to open if such an optional file does not exist, but we do want to + report a failure in opening for other reasons (e.g. we got an I/O + error, or the file is there, but we lack the permission to open). + + The exact errors we need to ignore are ENOENT (obviously) and + ENOTDIR (less obvious). Instead of repeating comparison of errno + with these two constants, introduce a helper function to do so. + + * We often try to open a file for reading whose existence is + optional, and silently ignore errors from open/fopen; report such + errors if they are not due to missing files. + + * When an existing repository is used for t/perf testing, we first + create bit-for-bit copy of it, which may grab a transient state of + the repository and freeze it into the repository used for testing, + which then may cause Git operations to fail. Single out "the index + being locked" case and forcibly drop the lock from the copy. + + * Three instances of the same helper function have been consolidated + to one. + + * "fast-import" uses a default pack chain depth that is consistent + with other parts of the system. + + * A new test to show the interaction between the pattern [^a-z] + (which matches '/') and a slash in a path has been added. The + pattern should not match the slash with "pathmatch", but should + with "wildmatch". + + * The 'diff-highlight' program (in contrib/) has been restructured + for easier reuse by an external project 'diff-so-fancy'. + + * A common pattern to free a piece of memory and assign NULL to the + pointer that used to point at it has been replaced with a new + FREE_AND_NULL() macro. + + * Traditionally, the default die() routine had a code to prevent it + from getting called multiple times, which interacted badly when a + threaded program used it (one downside is that the real error may + be hidden and instead the only error message given to the user may + end up being "die recursion detected", which is not very useful). + + * Introduce a "repository" object to eventually make it easier to + work in multiple repositories (the primary focus is to work with + the superproject and its submodules) in a single process. + + * Optimize "what are the object names already taken in an alternate + object database?" query that is used to derive the length of prefix + an object name is uniquely abbreviated to. + + * The hashmap API has been updated so that data to customize the + behaviour of the comparison function can be specified at the time a + hashmap is initialized. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v2.13 +----------------- + +Unless otherwise noted, all the fixes since v2.13 in the maintenance +track are contained in this release (see the maintenance releases' +notes for details). + + * "git gc" did not interact well with "git worktree"-managed + per-worktree refs. + + * "git cherry-pick" and other uses of the sequencer machinery + mishandled a trailer block whose last line is an incomplete line. + This has been fixed so that an additional sign-off etc. are added + after completing the existing incomplete line. + + * The codepath in "git am" that is used when running "git rebase" + leaked memory held for the log message of the commits being rebased. + + * "git clone --config var=val" is a way to populate the + per-repository configuration file of the new repository, but it did + not work well when val is an empty string. This has been fixed. + + * Setting "log.decorate=false" in the configuration file did not take + effect in v2.13, which has been corrected. + + * A few codepaths in "checkout" and "am" working on an unborn branch + tried to access an uninitialized piece of memory. + + * The Web interface to gmane news archive is long gone, even though + the articles are still accessible via NTTP. Replace the links with + ones to public-inbox.org. Because their message identification is + based on the actual message-id, it is likely that it will be easier + to migrate away from it if/when necessary. + + * The receive-pack program now makes sure that the push certificate + records the same set of push options used for pushing. + + * Tests have been updated to pass under GETTEXT_POISON (a mechanism + to ensure that output strings that should not be translated are + not translated by mistake), and TravisCI is told to run them. + + * "git checkout --recurse-submodules" did not quite work with a + submodule that itself has submodules. + + * "pack-objects" can stream a slice of an existing packfile out when + the pack bitmap can tell that the reachable objects are all needed + in the output, without inspecting individual objects. This + strategy however would not work well when "--local" and other + options are in use, and need to be disabled. + + * Fix memory leaks pointed out by Coverity (and people). + + * "git read-tree -m" (no tree-ish) gave a nonsense suggestion "use + --empty if you want to clear the index". With "-m", such a request + will still fail anyway, as you'd need to name at least one tree-ish + to be merged. + + * Make sure our tests would pass when the sources are checked out + with "platform native" line ending convention by default on + Windows. Some "text" files out tests use and the test scripts + themselves that are meant to be run with /bin/sh, ought to be + checked out with eol=LF even on Windows. + + * Introduce the BUG() macro to improve die("BUG: ..."). + + * Clarify documentation for include.path and includeIf.<condition>.path + configuration variables. + + * Git sometimes gives an advice in a rhetorical question that does + not require an answer, which can confuse new users and non native + speakers. Attempt to rephrase them. + + * A few http:// links that are redirected to https:// in the + documentation have been updated to https:// links. + + * "git for-each-ref --format=..." with %(HEAD) in the format used to + resolve the HEAD symref as many times as it had processed refs, + which was wasteful, and "git branch" shared the same problem. + + * Regression fix to topic recently merged to 'master'. + + * The shell completion script (in contrib/) learned "git stash" has + a new "push" subcommand. + + * "git interpret-trailers", when used as GIT_EDITOR for "git commit + -v", looked for and appended to a trailer block at the very end, + i.e. at the end of the "diff" output. The command has been + corrected to pay attention to the cut-mark line "commit -v" adds to + the buffer---the real trailer block should appear just before it. + + * A test allowed both "git push" and "git receive-pack" on the other + end write their traces into the same file. This is OK on platforms + that allows atomically appending to a file opened with O_APPEND, + but on other platforms led to a mangled output, causing + intermittent test failures. This has been fixed by disabling + traces from "receive-pack" in the test. + + * Tag objects, which are not reachable from any ref, that point at + missing objects were mishandled by "git gc" and friends (they + should silently be ignored instead) + + * "git describe --contains" penalized light-weight tags so much that + they were almost never considered. Instead, give them about the + same chance to be considered as an annotated tag that is the same + age as the underlying commit would. + + * The "run-command" API implementation has been made more robust + against dead-locking in a threaded environment. + + * A recent update to t5545-push-options.sh started skipping all the + tests in the script when a web server testing is disabled or + unavailable, not just the ones that require a web server. Non HTTP + tests have been salvaged to always run in this script. + + * "git send-email" now uses Net::SMTP::SSL, which is obsolete, only + when needed. Recent versions of Net::SMTP can do TLS natively. + + * "foo\bar\baz" in "git fetch foo\bar\baz", even though there is no + slashes in it, cannot be a nickname for a remote on Windows, as + that is likely to be a pathname on a local filesystem. + + * "git clean -d" used to clean directories that has ignored files, + even though the command should not lose ignored ones without "-x". + "git status --ignored" did not list ignored and untracked files + without "-uall". These have been corrected. + + * The result from "git diff" that compares two blobs, e.g. "git diff + $commit1:$path $commit2:$path", used to be shown with the full + object name as given on the command line, but it is more natural to + use the $path in the output and use it to look up .gitattributes. + + * The "collision detecting" SHA-1 implementation shipped with 2.13 + was quite broken on some big-endian platforms and/or platforms that + do not like unaligned fetches.

Using another project while maintaining independent history. + Submodules allow you to contain the working tree of another project + within your own working tree while keeping the history of both + projects separate. Also, since submodules are fixed to an arbitrary + version, the other project can be independently developed without + affecting the superproject, allowing the superproject project to + fix itself to new versions only when desired. + +2. Splitting a (logically single) project into multiple + repositories and tying them back together. This can be used to + overcome current limitations of Gits implementation to have + finer grained access: + + * Size of the git repository: + In its current form Git scales up poorly for large repositories containing + content that is not compressed by delta computation between trees. + However you can also use submodules to e.g. hold large binary assets + and these repositories are then shallowly cloned such that you do not + have a large history locally. + * Transfer size: + In its current form Git requires the whole working tree present. It + does not allow partial trees to be transferred in fetch or clone. + * Access control: + By restricting user access to submodules, this can be used to implement + read/write policies for different users. + +The configuration of submodules +------------------------------- + +Submodule operations can be configured using the following mechanisms +(from highest to lowest precedence): + + * The command line for those commands that support taking submodule specs. + Most commands have a boolean flag '--recurse-submodules' whether to + recurse into submodules. Examples are `ls-files` or `checkout`. + Some commands take enums, such as `fetch` and `push`, where you can + specify how submodules are affected. + + * The configuration inside the submodule. This includes `$GIT_DIR/config` + in the submodule, but also settings in the tree such as a `.gitattributes` + or `.gitignore` files that specify behavior of commands inside the + submodule. ++ +For example an effect from the submodule's `.gitignore` file +would be observed when you run `git status --ignore-submodules=none` in +the superproject. This collects information from the submodule's working +directory by running `status` in the submodule, which does pay attention +to its `.gitignore` file. ++ +The submodule's `$GIT_DIR/config` file would come into play when running +`git push --recurse-submodules=check` in the superproject, as this would +check if the submodule has any changes not published to any remote. The +remotes are configured in the submodule as usual in the `$GIT_DIR/config` +file. + + * The configuration file `$GIT_DIR/config` in the superproject. + Typical configuration at this place is controlling if a submodule + is recursed into at all via the `active` flag for example. ++ +If the submodule is not yet initialized, then the configuration +inside the submodule does not exist yet, so configuration where to +obtain the submodule from is configured here for example. + + * the `.gitmodules` file inside the superproject. Additionally to the + required mapping between submodule's name and path, a project usually + uses this file to suggest defaults for the upstream collection + of repositories. ++ +This file mainly serves as the mapping between name and path in +the superproject, such that the submodule's git directory can be +located. ++ +If the submodule has never been initialized, this is the only place +where submodule configuration is found. It serves as the last fallback +to specify where to obtain the submodule from. + +FORMS +----- + +Submodules can take the following forms: + + * The basic form described in DESCRIPTION with a Git directory, +a working directory, a `gitlink`, and a `.gitmodules` entry. + + * "Old-form" submodule: A working directory with an embedded +`.git` directory, and the tracking `gitlink` and `.gitmodules` entry in +the superproject. This is typically found in repositories generated +using older versions of Git. ++ +It is possible to construct these old form repositories manually. ++ +When deinitialized or deleted (see below), the submodule’s Git +directory is automatically moved to `$GIT_DIR/modules/<name>/` +of the superproject. + + * Deinitialized submodule: A `gitlink`, and a `.gitmodules` entry, +but no submodule working directory. The submodule’s git directory +may be there as after deinitializing the git directory is kept around. +The directory which is supposed to be the working directory is empty instead. ++ +A submodule can be deinitialized by running `git submodule deinit`. +Besides emptying the working directory, this command only modifies +the superproject’s `$GIT_DIR/config` file, so the superproject’s history +is not affected. This can be undone using `git submodule init`. + + * Deleted submodule: A submodule can be deleted by running +`git rm <submodule path> && git commit`. This can be undone +using `git revert`. ++ +The deletion removes the superproject’s tracking data, which are +both the `gitlink` entry and the section in the `.gitmodules` file. +The submodule’s working directory is removed from the file +system, but the Git directory is kept around as it to make it +possible to checkout past commits without requiring fetching +from another repository. ++ +To completely remove a submodule, manually delete +`$GIT_DIR/modules/<name>/`. + +Workflow for a third party library +---------------------------------- + + # add a submodule + git submodule add <url> <path> + + # occasionally update the submodule to a new version: + git -C <path> checkout <new version> + git add <path> + git commit -m "update submodule to new version" + + # See the list of submodules in a superproject + git submodule status + + # See FORMS on removing submodules + + +Workflow for an artificially split repo +-------------------------------------- + + # Enable recursion for relevant commands, such that + # regular commands recurse into submodules by default + git config --global submodule.recurse true + + # Unlike the other commands below clone still needs + # its own recurse flag: + git clone --recurse <URL> <directory> + cd <directory> + + # Get to know the code: + git grep foo + git ls-files + + # Get new code + git fetch + git pull --rebase + + # change worktree + git checkout + git reset + +Implementation details +---------------------- + +When cloning or pulling a repository containing submodules the submodules +will not be checked out by default; You can instruct 'clone' to recurse +into submodules.
