* When built with more recent cURL, GIT_SSL_VERSION can now specify
"tlsv1.3" as its value.
+ * "git gui" learned that "~/.ssh/id_ecdsa.pub" and
+ "~/.ssh/id_ed25519.pub" are also possible SSH key files.
+ (merge 2e2f0288ef bb/git-gui-ssh-key-files later to maint).
+
+ * "git gui" performs commit upon CTRL/CMD+ENTER but the
+ CTRL/CMD+KP_ENTER (i.e. enter key on the numpad) did not have the
+ same key binding. It now does.
+ (merge 28a1d94a06 bp/git-gui-bind-kp-enter later to maint).
+
+ * "git gui" has been taught to work with old versions of tk (like
+ 8.5.7) that do not support "ttk::style theme use" as a way to query
+ the current theme.
+ (merge 4891961105 cb/git-gui-ttk-style later to maint).
+
+ * "git rebase" has learned to honor "--signoff" option when using
+ backends other than "am" (but not "--preserve-merges").
+
+ * "git branch --list" during an interrupted "rebase -i" now lets
+ users distinguish the case where a detached HEAD is being rebased
+ and a normal branch is being rebased.
+
+ * "git mergetools" learned talking to guiffy.
+
+ * The scripts in contrib/emacs/ have outlived their usefulness and
+ have been replaced with a stub that errors out and tells the user
+ there are replacements.
+
+ * The new "checkout-encoding" attribute can ask Git to convert the
+ contents to the specified encoding when checking out to the working
+ tree (and the other way around when checking in).
+
+ * The "git config" command uses separate options e.g. "--int",
+ "--bool", etc. to specify what type the caller wants the value to
+ be interpreted as. 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. This has been corrected.
+
+ * Error messages from "git push" can be painted for more visibility.
+
+ * "git http-fetch" (deprecated) had an optional and experimental
+ "feature" to fetch only commits and/or trees, which nobody used.

* Small test-helper programs have been consolidated into a single

+ * Shell completion (in contrib) that gives list of paths have been
+ optimized somewhat.
+
+ * The index file is updated to record the fsmonitor section after a

+ spent.
+
+ * Performance measuring framework in t/perf learned to help bisecting
+ performance regressions.
+
+ * Some multi-word source filenames are being renamed to separate
+ words with dashes instead of underscores.
+
+ * An reusable "memory pool" implementation has been extracted from
+ fast-import.c, which in turn has become the first user of the
+ mem-pool API.
+
+ * A build-time option has been added to allow Git to be told to refer
+ to its associated files relative to the main binary, in the same
+ way that has been possible on Windows for quite some time, for
+ Linux, BSDs and Darwin.
+
+ * Precompute and store information necessary for ancestry traversal
+ in a separate file to optimize graph walking.
+
+ * The effort to pass the repository in-core structure throughout the
+ API continues. This round deals with the code that implements the
+ refs/replace/ mechanism.
+
+ * The build procedure "make DEVELOPER=YesPlease" learned to enable a
+ bit more warning options depending on the compiler used to help
+ developers more. There also is "make DEVOPTS=tokens" knob
+ available now, for those who want to help fixing warnings we
+ usually ignore, for example.
+
+ * A new version of the transport protocol is being worked on.
+
+ * The code to interface to GPG has been restructured somewhat to make
+ it cleaner to integrate with other types of signature systems later.
+

+NAME
+----
+git-commit-graph - Write and verify Git commit graph files
+
+
+SYNOPSIS
+--------
+[verse]
+'git commit-graph read' [--object-dir <dir>]
+'git commit-graph write' <options> [--object-dir <dir>]
+
+
+DESCRIPTION
+-----------
+
+Manage the serialized commit graph file.
+
+
+OPTIONS
+-------
+--object-dir::
+ Use given directory for the location of packfiles and commit graph
+ file. This parameter exists to specify the location of an alternate
+ that only has the objects directory, not a full .git directory. The
+ commit graph file is expected to be at <dir>/info/commit-graph and
+ the packfiles are expected to be in <dir>/pack.
+
+
+COMMANDS
+--------
+'write'::
+
+Write a commit graph file based on the commits found in packfiles.
++
+With the `--stdin-packs` option, generate the new commit graph by
+walking objects only in the specified pack-indexes. (Cannot be combined
+with --stdin-commits.)
++
+With the `--stdin-commits` option, generate the new commit graph by
+walking commits starting at the commits specified in stdin as a list
+of OIDs in hex, one OID per line. (Cannot be combined with
+--stdin-packs.)
++
+With the `--append` option, include all commits that are present in the
+existing commit-graph file.
+
+'read'::
+
+Read a graph file given by the commit-graph file and output basic
+details about the graph file. Used for debugging purposes.
+
+
+EXAMPLES
+--------
+
+* Write a commit graph file for the packed commits in your local .git folder.
++
+------------------------------------------------
+$ git commit-graph write
+------------------------------------------------
+
+* Write a graph file, extending the current graph file using commits
+* in <pack-index>.
++
+------------------------------------------------
+$ echo <pack-index> | git commit-graph write --stdin-packs
+------------------------------------------------
+
+* Write a graph file containing all reachable commits.
++
+------------------------------------------------
+$ git show-ref -s | git commit-graph write --stdin-commits
+------------------------------------------------
+
+* Write a graph file containing all commits in the current
+* commit-graph file along with those reachable from HEAD.
++
+------------------------------------------------
+$ git rev-parse HEAD | git commit-graph write --stdin-commits --append
+------------------------------------------------
+
+* Read basic information from the commit-graph file.

+`working-tree-encoding`
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Git recognizes files encoded in ASCII or one of its supersets (e.g.
+UTF-8, ISO-8859-1, ...) as text files. Files encoded in certain other
+encodings (e.g. UTF-16) are interpreted as binary and consequently
+built-in Git text processing tools (e.g. 'git diff') as well as most Git
+web front ends do not visualize the contents of these files by default.
+
+In these cases you can tell Git the encoding of a file in the working
+directory with the `working-tree-encoding` attribute. If a file with this
+attribute is added to Git, then Git reencodes the content from the
+specified encoding to UTF-8. Finally, Git stores the UTF-8 encoded
+content in its internal data structure (called "the index"). On checkout
+the content is reencoded back to the specified encoding.
+
+Please note that using the `working-tree-encoding` attribute may have a
+number of pitfalls:
+
+- Alternative Git implementations (e.g. JGit or libgit2) and older Git
+ versions (as of March 2018) do not support the `working-tree-encoding`
+ attribute. If you decide to use the `working-tree-encoding` attribute
+ in your repository, then it is strongly recommended to ensure that all
+ clients working with the repository support it.
+
+ For example, Microsoft Visual Studio resources files (`*.rc`) or
+ PowerShell script files (`*.ps1`) are sometimes encoded in UTF-16.
+ If you declare `*.ps1` as files as UTF-16 and you add `foo.ps1` with
+ a `working-tree-encoding` enabled Git client, then `foo.ps1` will be
+ stored as UTF-8 internally. A client without `working-tree-encoding`
+ support will checkout `foo.ps1` as UTF-8 encoded file. This will
+ typically cause trouble for the users of this file.
+
+ If a Git client, that does not support the `working-tree-encoding`
+ attribute, adds a new file `bar.ps1`, then `bar.ps1` will be
+ stored "as-is" internally (in this example probably as UTF-16).
+ A client with `working-tree-encoding` support will interpret the
+ internal contents as UTF-8 and try to convert it to UTF-16 on checkout.
+ That operation will fail and cause an error.
+
+- Reencoding content to non-UTF encodings can cause errors as the
+ conversion might not be UTF-8 round trip safe. If you suspect your
+ encoding to not be round trip safe, then add it to
+ `core.checkRoundtripEncoding` to make Git check the round trip
+ encoding (see linkgit:git-config[1]). SHIFT-JIS (Japanese character
+ set) is known to have round trip issues with UTF-8 and is checked by
+ default.
+
+- Reencoding content requires resources that might slow down certain
+ Git operations (e.g 'git checkout' or 'git add').
+
+Use the `working-tree-encoding` attribute only if you cannot store a file
+in UTF-8 encoding and if you want Git to be able to process the content
+as text.
+
+As an example, use the following attributes if your '*.ps1' files are
+UTF-16 encoded with byte order mark (BOM) and you want Git to perform
+automatic line ending conversion based on your platform.
+
+------------------------
+*.ps1 text working-tree-encoding=UTF-16
+------------------------
+
+Use the following attributes if your '*.ps1' files are UTF-16 little
+endian encoded without BOM and you want Git to use Windows line endings
+in the working directory. Please note, it is highly recommended to
+explicitly define the line endings with `eol` if the `working-tree-encoding`
+attribute is used to avoid ambiguity.
+
+------------------------
+*.ps1 text working-tree-encoding=UTF-16LE eol=CRLF
+------------------------
+
+You can get a list of all available encodings on your platform with the
+following command:
+
+------------------------
+iconv --list
+------------------------
+
+If you do not know the encoding of a file, then you can use the `file`
+command to guess the encoding:
+
+------------------------
+file foo.ps1
+------------------------
+
+

+Git commit graph format
+=======================
+
+The Git commit graph stores a list of commit OIDs and some associated
+metadata, including:
+
+- The generation number of the commit. Commits with no parents have
+ generation number 1; commits with parents have generation number
+ one more than the maximum generation number of its parents. We
+ reserve zero as special, and can be used to mark a generation
+ number invalid or as "not computed".
+
+- The root tree OID.
+
+- The commit date.
+
+- The parents of the commit, stored using positional references within
+ the graph file.
+
+These positional references are stored as unsigned 32-bit integers
+corresponding to the array position withing the list of commit OIDs. We
+use the most-significant bit for special purposes, so we can store at most
+(1 << 31) - 1 (around 2 billion) commits.
+
+== Commit graph files have the following format:
+
+In order to allow extensions that add extra data to the graph, we organize
+the body into "chunks" and provide a binary lookup table at the beginning
+of the body. The header includes certain values, such as number of chunks
+and hash type.
+
+All 4-byte numbers are in network order.
+
+HEADER:
+
+ 4-byte signature:
+ The signature is: {'C', 'G', 'P', 'H'}
+
+ 1-byte version number:
+ Currently, the only valid version is 1.
+
+ 1-byte Hash Version (1 = SHA-1)
+ We infer the hash length (H) from this value.
+
+ 1-byte number (C) of "chunks"
+
+ 1-byte (reserved for later use)
+ Current clients should ignore this value.
+
+CHUNK LOOKUP:
+
+ (C + 1) * 12 bytes listing the table of contents for the chunks:
+ First 4 bytes describe the chunk id. Value 0 is a terminating label.
+ Other 8 bytes provide the byte-offset in current file for chunk to
+ start. (Chunks are ordered contiguously in the file, so you can infer
+ the length using the next chunk position if necessary.) Each chunk
+ ID appears at most once.
+
+ The remaining data in the body is described one chunk at a time, and
+ these chunks may be given in any order. Chunks are required unless
+ otherwise specified.
+
+CHUNK DATA:
+
+ OID Fanout (ID: {'O', 'I', 'D', 'F'}) (256 * 4 bytes)
+ The ith entry, F[i], stores the number of OIDs with first
+ byte at most i. Thus F[255] stores the total
+ number of commits (N).
+
+ OID Lookup (ID: {'O', 'I', 'D', 'L'}) (N * H bytes)
+ The OIDs for all commits in the graph, sorted in ascending order.
+
+ Commit Data (ID: {'C', 'G', 'E', 'T' }) (N * (H + 16) bytes)
+ * The first H bytes are for the OID of the root tree.
+ * The next 8 bytes are for the positions of the first two parents
+ of the ith commit. Stores value 0xffffffff if no parent in that
+ position. If there are more than two parents, the second value
+ has its most-significant bit on and the other bits store an array
+ position into the Large Edge List chunk.
+ * The next 8 bytes store the generation number of the commit and
+ the commit time in seconds since EPOCH. The generation number
+ uses the higher 30 bits of the first 4 bytes, while the commit
+ time uses the 32 bits of the second 4 bytes, along with the lowest
+ 2 bits of the lowest byte, storing the 33rd and 34th bit of the
+ commit time.
+
+ Large Edge List (ID: {'E', 'D', 'G', 'E'}) [Optional]
+ This list of 4-byte values store the second through nth parents for
+ all octopus merges. The second parent value in the commit data stores
+ an array position within this list along with the most-significant bit
+ on. Starting at that array position, iterate through this list of commit
+ positions for the parents until reaching a value with the most-significant
+ bit on. The other bits correspond to the position of the last parent.

+Git Commit Graph Design Notes
+=============================
+
+Git walks the commit graph for many reasons, including:
+
+1. Listing and filtering commit history.
+2. Computing merge bases.
+
+These operations can become slow as the commit count grows. The merge
+base calculation shows up in many user-facing commands, such as 'merge-base'
+or 'status' and can take minutes to compute depending on history shape.
+
+There are two main costs here:
+
+1. Decompressing and parsing commits.
+2. Walking the entire graph to satisfy topological order constraints.
+
+The commit graph file is a supplemental data structure that accelerates
+commit graph walks. 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. This can
+ be remedied by duplicating or refactoring the current graft logic.
+
+- The 'commit-graph' subcommand does not have a "verify" mode that is
+ necessary for integration with fsck.
+
+- The file format includes room for precomputed generation numbers. These
+ are not currently computed, so all generation numbers will be marked as
+ 0 (or "uncomputed"). 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. This will mostly be accomplished by swapping a commit-date-ordered
+ priority queue with one ordered by generation number. The following
+ operations are important candidates:
+
+ - paint_down_to_common()
+ - 'log --topo-order'
+
+- Currently, parse_commit_gently() requires filling in the root tree
+ object for a commit. This passes through lookup_tree() and consequently
+ lookup_object(). Also, it calls lookup_commit() when loading the parents.
+ These method calls check the ODB for object existence, even if the
+ consumer does not need the content. For example, we do not need the
+ tree contents when computing merge bases. Now that commit parsing is
+ removed from the computation time, these lookup operations are the
+ slowest operations keeping graph walks from being fast. Consider
+ loading these objects without verifying their existence in the ODB and
+ only loading them fully when consumers need them. Consider a method
+ such as "ensure_tree_loaded(commit)" that fully loads a tree before
+ using commit->tree.
+
+- The current design uses the 'commit-graph' subcommand to generate the graph.
+ When this feature stabilizes enough to recommend to most users, we should
+ add automatic graph writes to common operations that create many commits.
+ For example, one could compute a graph on 'clone', 'fetch', or 'repack'
+ commands.
+
+- A server could provide a commit graph file as part of the network protocol
+ to avoid extra calculations by clients. This feature is only of benefit if
+ the user is willing to trust the file, because verifying the file is correct
+ is as hard as computing it from scratch.

+Type 5 is reserved for future expansion. Type 0 is invalid.
+
+=== Deltified representation
+
+Conceptually there are only four object types: commit, tree, tag and
+blob. However to save space, an object could be stored as a "delta" of
+another "base" object. These representations are assigned new types
+ofs-delta and ref-delta, which is only valid in a pack file.
+
+Both ofs-delta and ref-delta store the "delta" to be applied to
+another object (called 'base object') to reconstruct the object. The
+difference between them is, ref-delta directly encodes 20-byte base
+object name. If the base object is in the same pack, ofs-delta encodes
+the offset of the base object in the pack instead.
+
+The base object could also be deltified if it's in the same pack.
+Ref-delta can also refer to an object outside the pack (i.e. the
+so-called "thin pack"). When stored on disk however, the pack should
+be self contained to avoid cyclic dependency.
+
+The delta data is a sequence of instructions to reconstruct an object
+from the base object. If the base object is deltified, it must be
+converted to canonical form first. Each instruction appends more and
+more data to the target object until it's complete. There are two
+supported instructions so far: one for copy a byte range from the
+source object and one for inserting new data embedded in the
+instruction itself.
+
+Each instruction has variable length. Instruction type is determined
+by the seventh bit of the first octet. The following diagrams follow
+the convention in RFC 1951 (Deflate compressed data format).
+
+==== Instruction to copy from base object
+
+ +----------+---------+---------+---------+---------+-------+-------+-------+
+ | 1xxxxxxx | offset1 | offset2 | offset3 | offset4 | size1 | size2 | size3 |
+ +----------+---------+---------+---------+---------+-------+-------+-------+
+
+This is the instruction format to copy a byte range from the source
+object. It encodes the offset to copy from and the number of bytes to
+copy. Offset and size are in little-endian order.
+
+All offset and size bytes are optional. This is to reduce the
+instruction size when encoding small offsets or sizes. The first seven
+bits in the first octet determines which of the next seven octets is
+present. If bit zero is set, offset1 is present. If bit one is set
+offset2 is present and so on.
+
+Note that a more compact instruction does not change offset and size
+encoding. For example, if only offset2 is omitted like below, offset3
+still contains bits 16-23. It does not become offset2 and contains
+bits 8-15 even if it's right next to offset1.
+
+ +----------+---------+---------+
+ | 10000101 | offset1 | offset3 |
+ +----------+---------+---------+
+
+In its most compact form, this instruction only takes up one byte
+(0x80) with both offset and size omitted, which will have default
+values zero. There is another exception: size zero is automatically
+converted to 0x10000.
+
+==== Instruction to add new data
+
+ +----------+============+
+ | 0xxxxxxx | data |
+ +----------+============+
+
+This is the instruction to construct target object without the base
+object. The following data is appended to the target object. The first
+seven bits of the first octet determines the size of data in
+bytes. The size must be non-zero.

+ Git Wire Protocol, Version 2
+==============================
+
+This document presents a specification for a version 2 of Git's wire
+protocol. Protocol v2 will improve upon v1 in the following ways:
+
+ * Instead of multiple service names, multiple commands will be
+ supported by a single service
+ * Easily extendable as capabilities are moved into their own section
+ of the protocol, no longer being hidden behind a NUL byte and
+ limited by the size of a pkt-line
+ * Separate out other information hidden behind NUL bytes (e.g. agent
+ string as a capability and symrefs can be requested using 'ls-refs')
+ * Reference advertisement will be omitted unless explicitly requested
+ * ls-refs command to explicitly request some refs
+ * Designed with http and stateless-rpc in mind. With clear flush
+ semantics the http remote helper can simply act as a proxy
+
+In protocol v2 communication is command oriented. When first contacting a
+server a list of capabilities will advertised. Some of these capabilities
+will be commands which a client can request be executed. Once a command
+has completed, a client can reuse the connection and request that other
+commands be executed.
+
+ Packet-Line Framing
+---------------------
+
+All communication is done using packet-line framing, just as in v1. See
+`Documentation/technical/pack-protocol.txt` and
+`Documentation/technical/protocol-common.txt` for more information.
+
+In protocol v2 these special packets will have the following semantics:
+
+ * '0000' Flush Packet (flush-pkt) - indicates the end of a message
+ * '0001' Delimiter Packet (delim-pkt) - separates sections of a message
+
+ Initial Client Request
+------------------------
+
+In general a client can request to speak protocol v2 by sending
+`version=2` through the respective side-channel for the transport being
+used which inevitably sets `GIT_PROTOCOL`. More information can be
+found in `pack-protocol.txt` and `http-protocol.txt`. In all cases the
+response from the server is the capability advertisement.
+
+ Git Transport
+~~~~~~~~~~~~~~~
+
+When using the git:// transport, you can request to use protocol v2 by
+sending "version=2" as an extra parameter:
+
+ 003egit-upload-pack /project.git\0host=myserver.com\0\0version=2\0
+
+ SSH and File Transport
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+When using either the ssh:// or file:// transport, the GIT_PROTOCOL
+environment variable must be set explicitly to include "version=2".
+
+ HTTP Transport
+~~~~~~~~~~~~~~~~
+
+When using the http:// or https:// transport a client makes a "smart"
+info/refs request as described in `http-protocol.txt` and requests that
+v2 be used by supplying "version=2" in the `Git-Protocol` header.
+
+ C: Git-Protocol: version=2
+ C:
+ C: GET $GIT_URL/info/refs?service=git-upload-pack HTTP/1.0
+
+A v2 server would reply:
+
+ S: 200 OK
+ S: <Some headers>
+ S: ...
+ S:
+ S: 000eversion 2\n
+ S: <capability-advertisement>
+
+Subsequent requests are then made directly to the service
+`$GIT_URL/git-upload-pack`. (This works the same for git-receive-pack).
+
+ Capability Advertisement
+--------------------------
+
+A server which decides to communicate (based on a request from a client)
+using protocol version 2, notifies the client by sending a version string
+in its initial response followed by an advertisement of its capabilities.
+Each capability is a key with an optional value. Clients must ignore all
+unknown keys. Semantics of unknown values are left to the definition of
+each key. Some capabilities will describe commands which can be requested
+to be executed by the client.
+
+ capability-advertisement = protocol-version
+ capability-list
+ flush-pkt
+
+ protocol-version = PKT-LINE("version 2" LF)
+ capability-list = *capability
+ capability = PKT-LINE(key[=value] LF)
+
+ key = 1*(ALPHA | DIGIT | "-_")
+ value = 1*(ALPHA | DIGIT | " -_.,?\/{}[]()<>!@#$%^&*+=:;")
+
+ Command Request
+-----------------
+
+After receiving the capability advertisement, a client can then issue a
+request to select the command it wants with any particular capabilities
+or arguments. There is then an optional section where the client can
+provide any command specific parameters or queries. Only a single
+command can be requested at a time.
+
+ request = empty-request | command-request
+ empty-request = flush-pkt
+ command-request = command
+ capability-list
+ [command-args]
+ flush-pkt
+ command = PKT-LINE("command=" key LF)
+ command-args = delim-pkt
+ *command-specific-arg
+
+ command-specific-args are packet line framed arguments defined by
+ each individual command.
+
+The server will then check to ensure that the client's request is
+comprised of a valid command as well as valid capabilities which were
+advertised. 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. This is because the server will have already
+ determined the objects it plans to send to the client and no
+ further negotiation is needed.
+
+ shallow-info section
+ * If the client has requested a shallow fetch/clone, a shallow
+ client requests a fetch or the server is shallow then the
+ server's response may include a shallow-info section. The
+ shallow-info section will be included if (due to one of the
+ above conditions) the server needs to inform the client of any
+ shallow boundaries or adjustments to the clients already
+ existing shallow boundaries.
+
+ * Always begins with the section header "shallow-info"
+
+ * If a positive depth is requested, the server will compute the
+ set of commits which are no deeper than the desired depth.
+
+ * The server sends a "shallow obj-id" line for each commit whose
+ parents will not be sent in the following packfile.
+
+ * The server sends an "unshallow obj-id" line for each commit
+ which the client has indicated is shallow, but is no longer
+ shallow as a result of the fetch (due to its parents being
+ sent in the following packfile).
+
+ * The server MUST NOT send any "unshallow" lines for anything
+ which the client has not indicated was shallow as a part of
+ its request.
+
+ * This section is only included if a packfile section is also
+ included in the response.
+
+ packfile section
+ * This section is only included if the client has sent 'want'
+ lines in its request and either requested that no more
+ negotiation be done by sending 'done' or if the server has
+ decided it has found a sufficient cut point to produce a
+ packfile.
+
+ * Always begins with the section header "packfile"
+
+ * The transmission of the packfile begins immediately after the
+ section header
+
+ * The data transfer of the packfile is always multiplexed, using
+ the same semantics of the 'side-band-64k' capability from
+ protocol version 1. This means that each packet, during the
+ packfile data stream, is made up of a leading 4-byte pkt-line
+ length (typical of the pkt-line format), followed by a 1-byte
+ stream code, followed by the actual data.
+
+ The stream code can be one of:
+ 1 - pack data
+ 2 - progress messages
+ 3 - fatal error message just before stream aborts
+
+ server-option
+~~~~~~~~~~~~~~~
+
+If advertised, indicates that any number of server specific options can be
+included in a request. This is done by sending each option as a
+"server-option=<option>" capability line in the capability-list section of
+a request.
+
+The provided options must not contain a NUL or LF character.

these commits have no parents.
*********************************************************
-The basic idea is to write the SHA-1s of shallow commits into
-$GIT_DIR/shallow, and handle its contents like the contents
-of $GIT_DIR/info/grafts (with the difference that shallow
-cannot contain parent information).
-
-This information is stored in a new file instead of grafts, or
-even the config, since the user should not touch that file
-at all (even throughout development of the shallow clone, it
-was never manually edited!).
+$GIT_DIR/shallow lists commit object names and tells Git to
+pretend as if they are root commits (e.g. "git log" traversal
+stops after showing them; "git fsck" does not complain saying
+the commits listed on their "parent" lines do not exist).
Each line contains exactly one SHA-1. When read, a commit_graft
will be constructed, which has nr_parent < 0 to make it easier
to discern from user provided grafts.
+Note that the shallow feature could not be changed easily to
+use replace refs: a commit containing a `mergetag` is not allowed
+to be replaced, not even by a root commit. Such a commit can be
+made shallow, though. Also, having a `shallow` file explicitly
+listing all the commits made shallow makes it a *lot* easier to
+do shallow-specific things such as to deepen the history.
+
Since fsck-objects relies on the library to read the objects,
it honours shallow commits automatically.

* git.el:
- Status manager that displays the state of all the files of the

- commands. The user interface is as far as possible compatible with
- the pcl-cvs mode. It can be started with `M-x git-status'.
+ Wrapper for "git status" that provided access to other git commands.
+
+ Modern alternatives to this include Magit, and VC mode that ships

* git-blame.el:
- Emacs implementation of incremental git-blame. When you turn it on
- while viewing a file, the editor buffer will be updated by setting
- the background of individual lines to a color that reflects which
- commit it comes from. And when you move around the buffer, a
- one-line summary will be shown in the echo area.

+ mode learned to invoke git-blame, which can be done via C-x v g.

-;;; Commentary:
-;;
-;; Here is an Emacs implementation of incremental git-blame. When you
-;; turn it on while viewing a file, the editor buffer will be updated by
-;; setting the background of individual lines to a color that reflects
-;; which commit it comes from. And when you move around the buffer, a
-;; one-line summary will be shown in the echo area.
-
-;;; Installation:
-;;
-;; To use this package, put it somewhere in `load-path' (or add
-;; directory with git-blame.el to `load-path'), and add the following
-;; line to your .emacs:
-;;
-;; (require 'git-blame)
-;;
-;; If you do not want to load this package before it is necessary, you
-;; can make use of the `autoload' feature, e.g. by adding to your .emacs
-;; the following lines
-;;
-;; (autoload 'git-blame-mode "git-blame"
-;; "Minor mode for incremental blame for Git." t)
-;;
-;; Then first use of `M-x git-blame-mode' would load the package.
-
-;;; Compatibility:
-;;
-;; It requires GNU Emacs 21 or later and Git 1.5.0 and up
-;;
-;; If you'are using Emacs 20, try changing this:
-;;
-;; (overlay-put ovl 'face (list :background
-;; (cdr (assq 'color (cddddr info)))))
-;;
-;; to
-;;
-;; (overlay-put ovl 'face (cons 'background-color
-;; (cdr (assq 'color (cddddr info)))))

-;;; Commentary:
-
-;; This file contains an interface for the git version control
-;; system. It provides easy access to the most frequently used git
-;; commands. The user interface is as far as possible identical to
-;; that of the PCL-CVS mode.
-;;
-;; To install: put this file on the load-path and place the following
-;; in your .emacs file:
-;;
-;; (require 'git)
-;;
-;; To start: `M-x git-status'
-;;
-;; TODO
-;; - diff against other branch
-;; - renaming files from the status buffer
-;; - creating tags
-;; - fetch/pull
-;; - revlist browser
-;; - git-show-branch browser
-;;
-
-;;; Compatibility:
-;;
-;; This file works on GNU Emacs 21 or later. It may work on older
-;; versions but this is not guaranteed.
-;;
-;; It may work on XEmacs 21, provided that you first install the ewoc
-;; and log-edit packages.
