+ 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

-To make the modules available to Emacs, you should add this directory

+These were added shortly after Git was first released. Since then

+The following modules were available, and can be dug up from the Git
+history:
* git.el:
- Status manager that displays the state of all the files of the
- project, and provides easy access to the most frequently used git
- 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
+ with Emacs.
* 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.
+ A wrapper for "git blame" written before Emacs's own vc-annotate
+ 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.

+# SECTION 4: Partially renamed directory; still exists on both sides of merge
+#
+# What if we were to attempt to do directory rename detection when someone
+# "mostly" moved a directory but still left some files around, or,
+# equivalently, fully renamed a directory in one commmit and then recreated
+# that directory in a later commit adding some new files and then tried to
+# merge?
+#
+# It's hard to divine user intent in these cases, because you can make an
+# argument that, depending on the intermediate history of the side being
+# merged, that some users will want files in that directory to
+# automatically be detected and renamed, while users with a different
+# intermediate history wouldn't want that rename to happen.
+#
+# I think that it is best to simply not have directory rename detection
+# apply to such cases. My reasoning for this is four-fold: (1) it's
+# easiest for users in general to figure out what happened if we don't
+# apply directory rename detection in any such case, (2) it's an easy rule
+# to explain ["We don't do directory rename detection if the directory
+# still exists on both sides of the merge"], (3) we can get some hairy
+# edge/corner cases that would be really confusing and possibly not even
+# representable in the index if we were to even try, and [related to 3] (4)
+# attempting to resolve this issue of divining user intent by examining
+# intermediate history goes against the spirit of three-way merges and is a
+# path towards crazy corner cases that are far more complex than what we're
+# already dealing with.
+#
+# Note that the wording of the rule ("We don't do directory rename
+# detection if the directory still exists on both sides of the merge.")
+# also excludes "renaming" of a directory into a subdirectory of itself
+# (e.g. /some/dir/* -> /some/dir/subdir/*). It may be possible to carve
+# out an exception for "renaming"-beneath-itself cases without opening
+# weird edge/corner cases for other partial directory renames, but for now
+# we are keeping the rule simple.
