A new "--type=<typename>" option has been + introduced, which would make it cleaner to define new types. + + * "git config --get" learned the "--default" option, to help the + calling script. Building on top of the above changes, the + "git config" learns "--type=color" type. Taken together, you can + do things like "git config --get foo.color --default blue" and get + the ANSI color sequence for the color given to foo.color variable, + or "blue" if the variable does not exist. + + * "git ls-remote" learned an option to allow sorting its output based + on the refnames being shown. + + * The command line completion (in contrib/) has been taught that "git + stash save" has been deprecated ("git stash push" is the preferred + spelling in the new world) and does not offer it as a possible + completion candidate when "git stash push" can be. + + * "git gc --prune=nonsense" spent long time repacking and then + silently failed when underlying "git prune --expire=nonsense" + failed to parse its command line.

These lstat(2) calls are optimized + away by enumerating all loose objects beforehand. + It is unknown if the new strategy negatively affects existing use + cases, fetching into a repository with many loose objects from a + repository with small number of refs. + + * Git can be built to use either v1 or v2 of the PCRE library, and so + far, the build-time configuration USE_LIBPCRE=YesPlease instructed + the build procedure to use v1, but now it means v2.

If a user downgrades or disables the 'core.commitGraph' +config setting, then the existing ODB is sufficient. The file is stored +as "commit-graph" either in the .git/objects/info directory or in the info +directory of an alternate. + +The commit graph file stores the commit graph structure along with some +extra metadata to speed up graph walks. By listing commit OIDs in lexi- +cographic order, we can identify an integer position for each commit and +refer to the parents of a commit using those integer positions. We use +binary search to find initial commits and then use the integer positions +for fast lookups during the walk. + +A consumer may load the following info for a commit from the graph: + +1. The commit OID. +2. The list of parents, along with their integer position. +3. The commit date. +4. The root tree OID. +5. The generation number (see definition below). + +Values 1-4 satisfy the requirements of parse_commit_gently(). + +Define the "generation number" of a commit recursively as follows: + + * A commit with no parents (a root commit) has generation number one. + + * A commit with at least one parent has generation number one more than + the largest generation number among its parents. + +Equivalently, the generation number of a commit A is one more than the +length of a longest path from A to a root commit. The recursive definition +is easier to use for computation and observing the following property: + + If A and B are commits with generation numbers N and M, respectively, + and N <= M, then A cannot reach B. That is, we know without searching + that B is not an ancestor of A because it is further from a root commit + than A. + + Conversely, when checking if A is an ancestor of B, then we only need + to walk commits until all commits on the walk boundary have generation + number at most N. If we walk commits using a priority queue seeded by + generation numbers, then we always expand the boundary commit with highest + generation number and can easily detect the stopping condition. + +This property can be used to significantly reduce the time it takes to +walk commits and determine topological relationships. Without generation +numbers, the general heuristic is the following: + + If A and B are commits with commit time X and Y, respectively, and + X < Y, then A _probably_ cannot reach B. + +This heuristic is currently used whenever the computation is allowed to +violate topological relationships due to clock skew (such as "git log" +with default order), but is not used when the topological order is +required (such as merge base calculations, "git log --graph"). + +In practice, we expect some commits to be created recently and not stored +in the commit graph. We can treat these commits as having "infinite" +generation number and walk until reaching commits with known generation +number. + +Design Details +-------------- + +- The commit graph file is stored in a file named 'commit-graph' in the + .git/objects/info directory. This could be stored in the info directory + of an alternate. + +- The core.commitGraph config setting must be on to consume graph files. + +- The file format includes parameters for the object ID hash function, + so a future change of hash algorithm does not require a change in format. + +Future Work +----------- + +- The commit graph feature currently does not honor commit grafts.

A later patch will include this calculation. + +- After computing and storing generation numbers, we must make graph + walks aware of generation numbers to gain the performance benefits they + enable.

If the request is valid the server will then execute the +command. A server MUST wait till it has received the client's entire +request before issuing a response. The format of the response is +determined by the command being executed, but in all cases a flush-pkt +indicates the end of the response. + +When a command has finished, and the client has received the entire +response from the server, a client can either request that another +command be executed or can terminate the connection. A client may +optionally send an empty request consisting of just a flush-pkt to +indicate that no more requests will be made. + + Capabilities +-------------- + +There are two different types of capabilities: normal capabilities, +which can be used to to convey information or alter the behavior of a +request, and commands, which are the core actions that a client wants to +perform (fetch, push, etc). + +Protocol version 2 is stateless by default. This means that all commands +must only last a single round and be stateless from the perspective of the +server side, unless the client has requested a capability indicating that +state should be maintained by the server. Clients MUST NOT require state +management on the server side in order to function correctly. This +permits simple round-robin load-balancing on the server side, without +needing to worry about state management. + + agent +~~~~~~~ + +The server can advertise the `agent` capability with a value `X` (in the +form `agent=X`) to notify the client that the server is running version +`X`. The client may optionally send its own agent string by including +the `agent` capability with a value `Y` (in the form `agent=Y`) in its +request to the server (but it MUST NOT do so if the server did not +advertise the agent capability). The `X` and `Y` strings may contain any +printable ASCII characters except space (i.e., the byte range 32 < x < +127), and are typically of the form "package/version" (e.g., +"git/1.8.3.1"). The agent strings are purely informative for statistics +and debugging purposes, and MUST NOT be used to programmatically assume +the presence or absence of particular features. + + ls-refs +~~~~~~~~~ + +`ls-refs` is the command used to request a reference advertisement in v2. +Unlike the current reference advertisement, ls-refs takes in arguments +which can be used to limit the refs sent from the server. + +Additional features not supported in the base command will be advertised +as the value of the command in the capability advertisement in the form +of a space separated list of features: "<command>=<feature 1> <feature 2>" + +ls-refs takes in the following arguments: + + symrefs + In addition to the object pointed by it, show the underlying ref + pointed by it when showing a symbolic ref. + peel + Show peeled tags. + ref-prefix <prefix> + When specified, only references having a prefix matching one of + the provided prefixes are displayed. + +The output of ls-refs is as follows: + + output = *ref + flush-pkt + ref = PKT-LINE(obj-id SP refname *(SP ref-attribute) LF) + ref-attribute = (symref | peeled) + symref = "symref-target:" symref-target + peeled = "peeled:" obj-id + + fetch +~~~~~~~ + +`fetch` is the command used to fetch a packfile in v2. It can be looked +at as a modified version of the v1 fetch where the ref-advertisement is +stripped out (since the `ls-refs` command fills that role) and the +message format is tweaked to eliminate redundancies and permit easy +addition of future extensions. + +Additional features not supported in the base command will be advertised +as the value of the command in the capability advertisement in the form +of a space separated list of features: "<command>=<feature 1> <feature 2>" + +A `fetch` request can take the following arguments: + + want <oid> + Indicates to the server an object which the client wants to + retrieve. Wants can be anything and are not limited to + advertised objects. + + have <oid> + Indicates to the server an object which the client has locally. + This allows the server to make a packfile which only contains + the objects that the client needs. Multiple 'have' lines can be + supplied. + + done + Indicates to the server that negotiation should terminate (or + not even begin if performing a clone) and that the server should + use the information supplied in the request to construct the + packfile. + + thin-pack + Request that a thin pack be sent, which is a pack with deltas + which reference base objects not contained within the pack (but + are known to exist at the receiving end). This can reduce the + network traffic significantly, but it requires the receiving end + to know how to "thicken" these packs by adding the missing bases + to the pack. + + no-progress + Request that progress information that would normally be sent on + side-band channel 2, during the packfile transfer, should not be + sent. However, the side-band channel 3 is still used for error + responses. + + include-tag + Request that annotated tags should be sent if the objects they + point to are being sent. + + ofs-delta + Indicate that the client understands PACKv2 with delta referring + to its base by position in pack rather than by an oid. That is, + they can read OBJ_OFS_DELTA (ake type 6) in a packfile. + +If the 'shallow' feature is advertised the following arguments can be +included in the clients request as well as the potential addition of the +'shallow-info' section in the server's response as explained below. + + shallow <oid> + A client must notify the server of all commits for which it only + has shallow copies (meaning that it doesn't have the parents of + a commit) by supplying a 'shallow <oid>' line for each such + object so that the server is aware of the limitations of the + client's history. This is so that the server is aware that the + client may not have all objects reachable from such commits. + + deepen <depth> + Requests that the fetch/clone should be shallow having a commit + depth of <depth> relative to the remote side. + + deepen-relative + Requests that the semantics of the "deepen" command be changed + to indicate that the depth requested is relative to the client's + current shallow boundary, instead of relative to the requested + commits. + + deepen-since <timestamp> + Requests that the shallow clone/fetch should be cut at a + specific time, instead of depth. Internally it's equivalent to + doing "git rev-list --max-age=<timestamp>". Cannot be used with + "deepen". + + deepen-not <rev> + Requests that the shallow clone/fetch should be cut at a + specific revision specified by '<rev>', instead of a depth. + Internally it's equivalent of doing "git rev-list --not <rev>". + Cannot be used with "deepen", but can be used with + "deepen-since". + +The response of `fetch` is broken into a number of sections separated by +delimiter packets (0001), with each section beginning with its section +header. + + output = *section + section = (acknowledgments | shallow-info | packfile) + (flush-pkt | delim-pkt) + + acknowledgments = PKT-LINE("acknowledgments" LF) + (nak | *ack) + (ready) + ready = PKT-LINE("ready" LF) + nak = PKT-LINE("NAK" LF) + ack = PKT-LINE("ACK" SP obj-id LF) + + shallow-info = PKT-LINE("shallow-info" LF) + *PKT-LINE((shallow | unshallow) LF) + shallow = "shallow" SP obj-id + unshallow = "unshallow" SP obj-id + + packfile = PKT-LINE("packfile" LF) + *PKT-LINE(%x01-03 *%x00-ff) + + acknowledgments section + * If the client determines that it is finished with negotiations + by sending a "done" line, the acknowledgments sections MUST be + omitted from the server's response. + + * Always begins with the section header "acknowledgments" + + * The server will respond with "NAK" if none of the object ids sent + as have lines were common. + + * The server will respond with "ACK obj-id" for all of the + object ids sent as have lines which are common. + + * A response cannot have both "ACK" lines as well as a "NAK" + line. + + * The server will respond with a "ready" line indicating that + the server has found an acceptable common base and is ready to + make and send a packfile (which will be found in the packfile + section of the same response) + + * If the server has found a suitable cut point and has decided + to send a "ready" line, then the server can decide to (as an + optimization) omit any "ACK" lines it would have sent during + its response.

It will either create a new -repository, or incrementally import into an existing one. - -SVN access is done by the SVN::Perl module. - -git-svnimport assumes that SVN repositories are organized into one -"trunk" directory where the main development happens, "branches/FOO" -directories for branches, and "/tags/FOO" directories for tags. -Other subdirectories are ignored. - -git-svnimport creates a file ".git/svn2git", which is required for -incremental SVN imports. - -OPTIONS -------- --C <target-dir>:: - The GIT repository to import to. If the directory doesn't - exist, it will be created. Default is the current directory. - --s <start_rev>:: - Start importing at this SVN change number. The default is 1. -+ -When importing incrementally, you might need to edit the .git/svn2git file. - --i:: - Import-only: don't perform a checkout after importing. This option - ensures the working directory and index remain untouched and will - not create them if they do not exist. - --T <trunk_subdir>:: - Name the SVN trunk. Default "trunk". - --t <tag_subdir>:: - Name the SVN subdirectory for tags. Default "tags". - --b <branch_subdir>:: - Name the SVN subdirectory for branches. Default "branches". - --o <branch-for-HEAD>:: - The 'trunk' branch from SVN is imported to the 'origin' branch within - the git repository. Use this option if you want to import into a - different branch. - --r:: - Prepend 'rX: ' to commit messages, where X is the imported - subversion revision. - --u:: - Replace underscores in tag names with periods. - --I <ignorefile_name>:: - Import the svn:ignore directory property to files with this - name in each directory. (The Subversion and GIT ignore - syntaxes are similar enough that using the Subversion patterns - directly with "-I .gitignore" will almost always just work.) - --A <author_file>:: - Read a file with lines on the form -+ ------- - username = User's Full Name <email@addr.es> - ------- -+ -and use "User's Full Name <email@addr.es>" as the GIT -author and committer for Subversion commits made by -"username". If encountering a commit made by a user not in the -list, abort. -+ -For convenience, this data is saved to $GIT_DIR/svn-authors -each time the -A option is provided, and read from that same -file each time git-svnimport is run with an existing GIT -repository without -A. - --m:: - Attempt to detect merges based on the commit message. This option - will enable default regexes that try to capture the name source - branch name from the commit message. - --M <regex>:: - Attempt to detect merges based on the commit message with a custom - regex. It can be used with -m to also see the default regexes. - You must escape forward slashes. - --l <max_rev>:: - Specify a maximum revision number to pull. -+ -Formerly, this option controlled how many revisions to pull, -due to SVN memory leaks. (These have been worked around.) - --R <repack_each_revs>:: - Specify how often git repository should be repacked. -+ -The default value is 1000. git-svnimport will do imports in chunks of 1000 -revisions, after each chunk the git repository will be repacked. To disable -this behavior specify some large value here which is greater than the number of -revisions to import. - --P <path_from_trunk>:: - Partial import of the SVN tree. -+ -By default, the whole tree on the SVN trunk (/trunk) is imported. -'-P my/proj' will import starting only from '/trunk/my/proj'. -This option is useful when you want to import one project from a -svn repo which hosts multiple projects under the same trunk. - --v:: - Verbosity: let 'svnimport' report what it is doing. - --d:: - Use direct HTTP requests if possible. The "<path>" argument is used - only for retrieving the SVN logs; the path to the contents is - included in the SVN log. - --D:: - Use direct HTTP requests if possible. The "<path>" argument is used - for retrieving the logs, as well as for the contents. -+ -There's no safe way to automatically find out which of these options to -use, so you need to try both. Usually, the one that's wrong will die -with a 40x error pretty quickly. - -<SVN_repository_URL>:: - The URL of the SVN module you want to import. For local - repositories, use "file:///absolute/path". -+ -If you're using the "-d" or "-D" option, this is the URL of the SVN -repository itself; it usually ends in "/svn". - -<path>:: - The path to the module you want to check out. - --h:: - Print a short usage message and exit. - -OUTPUT ------- -If '-v' is specified, the script reports what it is doing. - -Otherwise, success is indicated the Unix way, i.e. by simply exiting with -a zero exit status. - -Author ------- -Written by Matthias Urlichs <smurf@smurf.noris.de>, with help from -various participants of the git-list <git@vger.kernel.org>. - -Based on a cvs2git script by the same author. - -Documentation --------------- -Documentation by Matthias Urlichs <smurf@smurf.noris.de>. - -GIT ---- -Part of the linkgit:git[7] suite diff --git a/contrib/examples/git-tag.sh b/contrib/examples/git-tag.sh deleted file mode 100755 index 1bd8f3c..0000000 --- a/contrib/examples/git-tag.sh +++ /dev/null @@ -1,205 +0,0 @@ -#!/bin/sh -# Copyright (c) 2005 Linus Torvalds - -USAGE='[-n [<num>]] -l [<pattern>] | [-a | -s | -u <key-id>] [-f | -d | -v] [-m <msg>] <tagname> [<head>]' -SUBDIRECTORY_OK='Yes' -. git-sh-setup - -message_given= -annotate= -signed= -force= -message= -username= -list= -verify= -LINES=0 -while test $# != 0 -do - case "$1" in - -a) - annotate=1 - shift - ;; - -s) - annotate=1 - signed=1 - shift - ;; - -f) - force=1 - shift - ;; - -n) - case "$#,$2" in - 1,* | *,-*) - LINES=1 # no argument - ;; - *) shift - LINES=$(expr "$1" : '\([0-9]*\)') - [ -z "$LINES" ] && LINES=1 # 1 line is default when -n is used - ;; - esac - shift - ;; - -l) - list=1 - shift - case $# in - 0) PATTERN= - ;; - *) - PATTERN="$1" # select tags by shell pattern, not re - shift - ;; - esac - git rev-parse --symbolic --tags | sort | - while read TAG - do - case "$TAG" in - *$PATTERN*) ;; - *) continue ;; - esac - [ "$LINES" -le 0 ] && { echo "$TAG"; continue ;} - OBJTYPE=$(git cat-file -t "$TAG") - case $OBJTYPE in - tag) - ANNOTATION=$(git cat-file tag "$TAG" | - sed -e '1,/^$/d' | - sed -n -e " - /^-----BEGIN PGP SIGNATURE-----\$/q - 2,\$s/^/ / - p - ${LINES}q - ") - printf "%-15s %s\n" "$TAG" "$ANNOTATION" - ;; - *) echo "$TAG" - ;; - esac - done - ;; - -m) - annotate=1 - shift - message="$1" - if test "$#" = "0"; then - die "error: option -m needs an argument" - else - message="$1" - message_given=1 - shift - fi - ;; - -F) - annotate=1 - shift - if test "$#" = "0"; then - die "error: option -F needs an argument" - else - message="$(cat "$1")" - message_given=1 - shift - fi - ;; - -u) - annotate=1 - signed=1 - shift - if test "$#" = "0"; then - die "error: option -u needs an argument" - else - username="$1" - shift - fi - ;; - -d) - shift - had_error=0 - for tag - do - cur=$(git show-ref --verify --hash -- "refs/tags/$tag") || { - echo >&2 "Seriously, what tag are you talking about?" - had_error=1 - continue - } - git update-ref -m 'tag: delete' -d "refs/tags/$tag" "$cur" || { - had_error=1 - continue - } - echo "Deleted tag $tag." - done - exit $had_error - ;; - -v) - shift - tag_name="$1" - tag=$(git show-ref --verify --hash -- "refs/tags/$tag_name") || - die "Seriously, what tag are you talking about?" - git-verify-tag -v "$tag" - exit $?
