+Git 2.22 Release Notes
+======================
+
+Updates since v2.21
+-------------------
+
+UI, Workflows & Features
+
+ * "git checkout --no-overlay" can be used to trigger a new mode of
+ checking out paths out of the tree-ish, that allows paths that
+ match the pathspec that are in the current index and working tree
+ and are not in the tree-ish.
+
+ * The %(trailers) formatter in "git log --format=..." now allows to
+ optionally pick trailers selectively by keyword, show only values,
+ etc.
+
+ * Four new configuration variables {author,committer}.{name,email}
+ have been introduced to override user.{name,email} in more specific
+ cases.
+
+ * Command-line completion (in contrib/) learned to tab-complete the
+ "git submodule absorbgitdirs" subcommand.
+
+ * "git branch" learned a new subcommand "--show-current".
+
+ * Output from "diff --cc" did not show the original paths when the
+ merge involved renames. A new option adds the paths in the
+ original trees to the output.
+
+ * The command line completion (in contrib/) has been taught to
+ complete more subcommand parameters.
+
+ * The final report from "git bisect" used to show the suspected
+ culprit using a raw "diff-tree", with which there is no output for
+ a merge commit. This has been updated to use a more modern and
+ human readable output that still is concise enough.
+
+ * "git rebase --rebase-merges" replaces its old "--preserve-merges"
+ option; the latter is now marked as deprecated.
+
+ * Error message given while cloning with --recurse-submodules has
+ been updated.
+
+ * The completion helper code now pays attention to repository-local
+ configuration (when available), which allows --list-cmds to honour
+ a repository specific setting of completion.commands, for example.
+
+ * "git mergetool" learned to offer Sublime Merge (smerge) as one of
+ its backends.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The diff machinery, one of the oldest parts of the system, which
+ long predates the parse-options API, uses fairly long and complex
+ handcrafted option parser. This is being rewritten to use the
+ parse-options API.
+
+ * The implementation of pack-redundant has been updated for
+ performance in a repository with many packfiles.
+
+ * A more structured way to obtain execution trace has been added.
+
+ * "git prune" has been taught to take advantage of reachability
+ bitmap when able.
+
+ * The command line parser of "git commit-tree" has been rewritten to
+ use the parse-options API.
+
+ * Suggest GitGitGadget instead of submitGit as a way to submit
+ patches based on GitHub PR to us.
+
+ * The test framework has been updated to help developers by making it
+ easier to run most of the tests under different versions of
+ over-the-wire protocols.
+
+ * Dev support update to make it easier to compare two formatted
+ results from our documentation.
+
+ * The scripted "git rebase" implementation has been retired.
+
+ * "git multi-pack-index verify" did not scale well with the number of
+ packfiles, which is being improved.
+
+ * "git stash" has been rewritten in C.
+
+ * The "check-docs" Makefile target to support developers has been
+ updated.
+
+ * The tests have been updated not to rely on the abbreviated option
+ names the parse-options API offers, to protect us from an
+ abbreviated form of an option that used to be unique within the
+ command getting non-unique when a new option that share the same
+ prefix is added.
+
+
+Fixes since v2.21
+-----------------
+
+ * "git prune-packed" did not notice and complain against excess
+ arguments given from the command line, which now it does.
+ (merge 9b0bd87ed2 rj/prune-packed-excess-args later to maint).
+
+ * Split-index fix.
+ (merge 6e37c8ed3c nd/split-index-null-base-fix later to maint).
+
+ * "git diff --no-index" may still want to access Git goodies like
+ --ext-diff and --textconv, but so far these have been ignored,
+ which has been corrected.
+ (merge 287ab28bfa jk/diff-no-index-initialize later to maint).
+
+ * Unify RPC code for smart http in protocol v0/v1 and v2, which fixes
+ a bug in the latter (lack of authentication retry) and generally
+ improves the code base.
+ (merge a97d00799a jt/http-auth-proto-v2-fix later to maint).
+
+ * The include file compat/bswap.h has been updated so that it is safe
+ to (accidentally) include it more than once.
+ (merge 33aa579a55 jk/guard-bswap-header later to maint).
+
+ * The set of header files used by "make hdr-check" unconditionally
+ included sha256/gcrypt.h, even when it is not used, causing the
+ make target to fail. We now skip it when GCRYPT_SHA256 is not in
+ use.
+ (merge f23aa18e7f rj/hdr-check-gcrypt-fix later to maint).
+
+ * The Makefile uses 'find' utility to enumerate all the *.h header
+ files, which is expensive on platforms with slow filesystems; it
+ now optionally uses "ls-files" if working within a repository,
+ which is a trick similar to how all sources are enumerated to run
+ ETAGS on.
+ (merge 92b88eba9f js/find-lib-h-with-ls-files-when-possible later to maint).
+
+ * "git rebase" that was reimplemented in C did not set ORIG_HEAD
+ correctly, which has been corrected.
+ (merge cbd29ead92 js/rebase-orig-head-fix later to maint).
+
+ * Dev support.
+ (merge f545737144 js/stress-test-ui-tweak later to maint).
+
+ * CFLAGS now can be tweaked when invoking Make while using
+ DEVELOPER=YesPlease; this did not work well before.
+ (merge 6d5d4b4e93 ab/makefile-help-devs-more later to maint).
+
+ * "git fsck --connectivity-only" omits computation necessary to sift
+ the objects that are not reachable from any of the refs into
+ unreachable and dangling. This is now enabled when dangling
+ objects are requested (which is done by default, but can be
+ overridden with the "--no-dangling" option).
+ (merge 8d8c2a5aef jk/fsck-doc later to maint).
+
+ * On platforms where "git fetch" is killed with SIGPIPE (e.g. OSX),
+ the upload-pack that runs on the other end that hangs up after
+ detecting an error could cause "git fetch" to die with a signal,
+ which led to a flakey test. "git fetch" now ignores SIGPIPE during
+ the network portion of its operation (this is not a problem as we
+ check the return status from our write(2)s).
+ (merge 143588949c jk/no-sigpipe-during-network-transport later to maint).
+
+ * A recent update broke "is this object available to us?" check for
+ well-known objects like an empty tree (which should yield "yes",
+ even when there is no on-disk object for an empty tree), which has
+ been corrected.
+ (merge f06ab027ef jk/virtual-objects-do-exist later to maint).
+
+ * The setup code has been cleaned up to avoid leaks around the
+ repository_format structure.
+ (merge e8805af1c3 ma/clear-repository-format later to maint).
+
+ * "git config --type=color ..." is meant to replace "git config --get-color"
+ but there is a slight difference that wasn't documented, which is
+ now fixed.
+ (merge cd8e7593b9 jk/config-type-color-ends-with-lf later to maint).
+
+ * When the "clean" filter can reduce the size of a huge file in the
+ working tree down to a small "token" (a la Git LFS), there is no
+ point in allocating a huge scratch area upfront, but the buffer is
+ sized based on the original file size. The convert mechanism now
+ allocates very minimum and reallocates as it receives the output
+ from the clean filter process.
+ (merge 02156ab031 jh/resize-convert-scratch-buffer later to maint).
+
+ * "git rebase" uses the refs/rewritten/ hierarchy to store its
+ intermediate states, which inherently makes the hierarchy per
+ worktree, but it didn't quite work well.
+ (merge b9317d55a3 nd/rewritten-ref-is-per-worktree later to maint).
+
+ * "git log -L<from>,<to>:<path>" with "-s" did not suppress the patch
+ output as it should. This has been corrected.
+ (merge 05314efaea jk/line-log-with-patch later to maint).
+
+ * "git worktree add" used to do a "find an available name with stat
+ and then mkdir", which is race-prone. This has been fixed by using
+ mkdir and reacting to EEXIST in a loop.
+ (merge 7af01f2367 ms/worktree-add-atomic-mkdir later to maint).
+
+ * Build update for SHA-1 with collision detection.
+ (merge 07a20f569b jk/sha1dc later to maint).
+
+ * Build procedure has been fixed around use of asciidoctor instead of
+ asciidoc.
+ (merge 185f9a0ea0 ma/asciidoctor-fixes later to maint).
+
+ * remote-http transport did not anonymize URLs reported in its error
+ messages at places.
+ (merge c1284b21f2 js/anonymize-remote-curl-diag later to maint).
+
+ * Error messages given from the http transport have been updated so
+ that they can be localized.
+ (merge ed8b4132c8 js/remote-curl-i18n later to maint).
+
+ * "git init" forgot to read platform-specific repository
+ configuration, which made Windows port to ignore settings of
+ core.hidedotfiles, for example.
+
+ * A corner-case object name ambiguity while the sequencer machinery
+ is working (e.g. "rebase -i -x") has been fixed.
+
+ * "git format-patch" did not diagnose an error while opening the
+ output file for the cover-letter, which has been corrected.
+ (merge 2fe95f494c jc/format-patch-error-check later to maint).
+
+ * "git checkout -f <branch>" while the index has an unmerged path
+ incorrectly left some paths in an unmerged state, which has been
+ corrected.
+
+ * A corner case bug in the refs API has been corrected.
+ (merge d3322eb28b jk/refs-double-abort later to maint).
+
+ * Unicode update.
+ (merge 584b62c37b bb/unicode-12 later to maint).
+
+ * dumb-http walker has been updated to share more error recovery
+ strategy with the normal codepath.
+
+ * A buglet in configuration parser has been fixed.
+ (merge 19e7fdaa58 nd/include-if-wildmatch later to maint).
+
+ * The documentation for "git read-tree --reset -u" has been updated.
+ (merge b5a0bd694c nd/read-tree-reset-doc later to maint).
+
+ * Code cleanup, docfix, build fix, etc.
+ (merge 11f470aee7 jc/test-yes-doc later to maint).

diff.ignoreSubmodules::
Sets the default value of --ignore-submodules. Note that this
vice versa by configuring the `fsck.<msg-id>` setting where the
`<msg-id>` is the fsck message ID and the value is one of `error`,
`warn` or `ignore`. For convenience, fsck prefixes the error/warning

gc.auto::
When there are approximately more than this many loose

+otherwise use to determine if there's work to do, such as
+`gc.autoPackLimit`.
gc.autoPackLimit::

will be repacked. After this the number of packs should go below
gc.autoPackLimit and gc.bigPackThreshold should be respected again.

--connectivity-only::
- Check only the connectivity of tags, commits and tree objects. By

- expense of missing corrupt objects or other problematic issues.
+ Check only the connectivity of reachable objects, making sure
+ that any objects referenced by a reachable tag, commit, or tree
+ is present. This speeds up the operation by avoiding reading
+ blobs entirely (though it does still check that referenced blobs
+ exist). This will detect corruption in commits and trees, but
+ not do any semantic checks (e.g., for format errors). Corruption
+ in blob objects will not be detected at all.
++
+Unreachable tags, commits, and trees will also be accessed to find the
+tips of dangling segments of history. Use `--no-dangling` if you don't
+care about this output and want to speed it up further.
--strict::
Enable more strict checking, namely to catch a file mode
reflog, rerere metadata or stale working trees. May also update ancillary
indexes such as the commit-graph.
-Users are encouraged to run this task on a regular basis within
-each repository to maintain good disk space utilization and good
-operating performance.
+When common porcelain operations that create objects are run, they
+will check whether the repository has grown substantially since the
+last maintenance, and if so run `git gc` automatically. See `gc.auto`
+below for how to disable this behavior.
-Some git commands may automatically run 'git gc'; see the `--auto` flag
-below for details. If you know what you're doing and all you want is to
-disable this behavior permanently without further considerations, just do:
-
-----------------------
-$ git config --global gc.auto 0
-----------------------
+Running `git gc` manually should only be needed when adding objects to
+a repository without regularly running such porcelain commands, to do
+a one-off repository optimization, or e.g. to clean up a suboptimal
+mass-import. See the "PACKFILE OPTIMIZATION" section in
+linkgit:git-fast-import[1] for more details on the import case.
OPTIONS
-------
space utilization and performance. This option will cause
'git gc' to more aggressively optimize the repository at the expense
of taking much more time. The effects of this optimization are
- persistent, so this option only needs to be used occasionally; every
- few hundred changesets or so.
+ mostly persistent. See the "AGGRESSIVE" section below for details.
--auto::
With this option, 'git gc' checks whether any housekeeping is
required; if not, it exits without performing any work.
- Some git commands run `git gc --auto` after performing
- operations that could create many loose objects. Housekeeping
- is required if there are too many loose objects or too many
- packs in the repository.
-+
-If the number of loose objects exceeds the value of the `gc.auto`
-configuration variable, then all loose objects are combined into a
-single pack using `git repack -d -l`. Setting the value of `gc.auto`
-to 0 disables automatic packing of loose objects.
+
-If the number of packs exceeds the value of `gc.autoPackLimit`,
-then existing packs (except those marked with a `.keep` file
-or over `gc.bigPackThreshold` limit)
-are consolidated into a single pack by using the `-A` option of
-'git repack'.
-If the amount of memory is estimated not enough for `git repack` to
-run smoothly and `gc.bigPackThreshold` is not set, the largest
-pack will also be excluded (this is the equivalent of running `git gc`
-with `--keep-base-pack`).
-Setting `gc.autoPackLimit` to 0 disables automatic consolidation of
-packs.
+See the `gc.auto` option in the "CONFIGURATION" section below for how
+this heuristic works.
+
-If houskeeping is required due to many loose objects or packs, all
+Once housekeeping is triggered by exceeding the limits of
+configuration options such as `gc.auto` and `gc.autoPackLimit`, all
other housekeeping tasks (e.g. rerere, working trees, reflog...) will
be performed as well.
--prune=<date>::
Prune loose objects older than date (default is 2 weeks ago,
overridable by the config variable `gc.pruneExpire`).
- --prune=all prunes loose objects regardless of their age and
+ --prune=now prunes loose objects regardless of their age and
increases the risk of corruption if another process is writing to
the repository concurrently; see "NOTES" below. --prune is on by
default.
`.keep` files are consolidated into a single pack. When this
option is used, `gc.bigPackThreshold` is ignored.
+AGGRESSIVE
+----------
+
+When the `--aggressive` option is supplied, linkgit:git-repack[1] will
+be invoked with the `-f` flag, which in turn will pass
+`--no-reuse-delta` to linkgit:git-pack-objects[1]. This will throw
+away any existing deltas and re-compute them, at the expense of
+spending much more time on the repacking.
+
+The effects of this are mostly persistent, e.g. when packs and loose
+objects are coalesced into one another pack the existing deltas in
+that pack might get re-used, but there are also various cases where we
+might pick a sub-optimal delta from a newer pack instead.
+
+Furthermore, supplying `--aggressive` will tweak the `--depth` and
+`--window` options passed to linkgit:git-repack[1]. See the

CONFIGURATION
-------------
-The optional configuration variable `gc.reflogExpire` can be
-set to indicate how long historical entries within each branch's
-reflog should remain available in this repository. The setting is
-expressed as a length of time, for example '90 days' or '3 months'.
-It defaults to '90 days'.
-
-The optional configuration variable `gc.reflogExpireUnreachable`
-can be set to indicate how long historical reflog entries which
-are not part of the current branch should remain available in
-this repository. These types of entries are generally created as
-a result of using `git commit --amend` or `git rebase` and are the
-commits prior to the amend or rebase occurring. Since these changes
-are not part of the current project most users will want to expire
-them sooner. This option defaults to '30 days'.
-
-The above two configuration variables can be given to a pattern. For
-example, this sets non-default expiry values only to remote-tracking
-branches:
-
-------------
-[gc "refs/remotes/*"]
- reflogExpire = never
- reflogExpireUnreachable = 3 days
-------------
-
-The optional configuration variable `gc.rerereResolved` indicates
-how long records of conflicted merge you resolved earlier are
-kept. This defaults to 60 days.
-
-The optional configuration variable `gc.rerereUnresolved` indicates
-how long records of conflicted merge you have not resolved are
-kept. This defaults to 15 days.
-
-The optional configuration variable `gc.packRefs` determines if
-'git gc' runs 'git pack-refs'. This can be set to "notbare" to enable
-it within all non-bare repos or it can be set to a boolean value.
-This defaults to true.
-
-The optional configuration variable `gc.writeCommitGraph` determines if
-'git gc' should run 'git commit-graph write'. This can be set to a
-boolean value. This defaults to false.
-
-The optional configuration variable `gc.aggressiveWindow` controls how
-much time is spent optimizing the delta compression of the objects in
-the repository when the --aggressive option is specified. The larger
-the value, the more time is spent optimizing the delta compression. See
-the documentation for the --window option in linkgit:git-repack[1] for
-more details. This defaults to 250.
-
-Similarly, the optional configuration variable `gc.aggressiveDepth`
-controls --depth option in linkgit:git-repack[1]. This defaults to 50.
-
-The optional configuration variable `gc.pruneExpire` controls how old
-the unreferenced loose objects have to be before they are pruned. The
-default is "2 weeks ago".
-
-Optional configuration variable `gc.worktreePruneExpire` controls how
-old a stale working tree should be before `git worktree prune` deletes
-it. Default is "3 months ago".

+= Trace2 API
+
+The Trace2 API can be used to print debug, performance, and telemetry
+information to stderr or a file. The Trace2 feature is inactive unless
+explicitly enabled by enabling one or more Trace2 Targets.
+
+The Trace2 API is intended to replace the existing (Trace1)
+printf-style tracing provided by the existing `GIT_TRACE` and
+`GIT_TRACE_PERFORMANCE` facilities. During initial implementation,
+Trace2 and Trace1 may operate in parallel.
+
+The Trace2 API defines a set of high-level messages with known fields,
+such as (`start`: `argv`) and (`exit`: {`exit-code`, `elapsed-time`}).
+
+Trace2 instrumentation throughout the Git code base sends Trace2
+messages to the enabled Trace2 Targets. Targets transform these
+messages content into purpose-specific formats and write events to
+their data streams. In this manner, the Trace2 API can drive
+many different types of analysis.
+
+Targets are defined using a VTable allowing easy extension to other
+formats in the future. This might be used to define a binary format,
+for example.
+
+== Trace2 Targets
+
+Trace2 defines the following set of Trace2 Targets.
+Format details are given in a later section.
+
+`GIT_TR2` (NORMAL)::
+
+ a simple printf format like GIT_TRACE.
++
+------------
+$ export GIT_TR2=~/log.normal
+$ git version
+git version 2.20.1.155.g426c96fcdb
+------------

+12:28:42.621250 trace2/tr2_tgt_normal.c:124 atexit elapsed:0.001265 code:0
+------------
+
+`GIT_TR2_PERF` (PERF)::
+
+ a column-based format to replace GIT_TRACE_PERFORMANCE suitable for
+ development and testing, possibly to complement tools like gprof.
++
+------------
+$ export GIT_TR2_PERF=~/log.perf
+$ git version
+git version 2.20.1.155.g426c96fcdb
+------------
++
+------------
+$ cat ~/log.perf
+12:28:42.620675 common-main.c:38 | d0 | main | version | | | | | 2.20.1.155.g426c96fcdb

+12:28:42.621259 trace2/tr2_tgt_perf.c:211 | d0 | main | atexit | | 0.001265 | | | code:0
+------------
+
+`GIT_TR2_EVENT` (EVENT)::
+
+ a JSON-based format of event data suitable for telemetry analysis.
++
+------------
+$ export GIT_TR2_EVENT=~/log.event
+$ git version
+git version 2.20.1.155.g426c96fcdb

+------------
+
+== Enabling a Target
+
+A Trace2 Target is enabled when the corresponding environment variable
+(`GIT_TR2`, `GIT_TR2_PERF`, or `GIT_TR2_EVENT`) is set. The following
+values are recognized.
+
+`0`::
+`false`::
+
+ Disables the target.
+
+`1`::
+`true`::
+
+ Enables the target and writes stream to `STDERR`.
+
+`[2-9]`::
+
+ Enables the target and writes to the already opened file descriptor.
+
+`<absolute-pathname>`::
+
+ Enables the target, opens and writes to the file in append mode.
+
+`af_unix:[<socket_type>:]<absolute-pathname>`::
+
+ Enables the target, opens and writes to a Unix Domain Socket
+ (on platforms that support them).
++
+Socket type can be either `stream` or `dgram`. If the socket type is
+omitted, Git will try both.
+
+== Trace2 API
+
+All public Trace2 functions and macros are defined in `trace2.h` and
+`trace2.c`. All public symbols are prefixed with `trace2_`.
+
+There are no public Trace2 data structures.
+
+The Trace2 code also defines a set of private functions and data types
+in the `trace2/` directory. These symbols are prefixed with `tr2_`
+and should only be used by functions in `trace2.c`.
+
+== Conventions for Public Functions and Macros
+
+The functions defined by the Trace2 API are declared and documented
+in `trace2.h`. It defines the API functions and wrapper macros for
+Trace2.
+
+Some functions have a `_fl()` suffix to indicate that they take `file`
+and `line-number` arguments.
+
+Some functions have a `_va_fl()` suffix to indicate that they also
+take a `va_list` argument.
+
+Some functions have a `_printf_fl()` suffix to indicate that they also
+take a varargs argument.
+
+There are CPP wrapper macros and ifdefs to hide most of these details.
+See `trace2.h` for more details. The following discussion will only
+describe the simplified forms.
+
+== Public API
+
+All Trace2 API functions send a messsage to all of the active
+Trace2 Targets. This section describes the set of available
+messages.
+
+It helps to divide these functions into groups for discussion
+purposes.
+
+=== Basic Command Messages
+
+These are concerned with the lifetime of the overall git process.
+
+`void trace2_initialize()`::
+
+ Determines if any Trace2 Targets should be enabled and
+ initializes the Trace2 facility. This includes starting the
+ elapsed time clocks and thread local storage (TLS).
++
+This function emits a "version" message containing the version of git
+and the Trace2 protocol.
++
+This function should be called from `main()` as early as possible in
+the life of the process.
+
+`int trace2_is_enabled()`::
+
+ Returns 1 if Trace2 is enabled (at least one target is
+ active).
+
+`void trace2_cmd_start(int argc, const char **argv)`::
+
+ Emits a "start" message containing the process command line
+ arguments.
+
+`int trace2_cmd_exit(int exit_code)`::
+
+ Emits an "exit" message containing the process exit-code and
+ elapsed time.
++
+Returns the exit-code.
+
+`void trace2_cmd_error(const char *fmt, va_list ap)`::
+
+ Emits an "error" message containing a formatted error message.
+
+`void trace2_cmd_path(const char *pathname)`::
+
+ Emits a "cmd_path" message with the full pathname of the
+ current process.
+
+=== Command Detail Messages
+
+These are concerned with describing the specific Git command
+after the command line, config, and environment are inspected.
+
+`void trace2_cmd_name(const char *name)`::
+
+ Emits a "cmd_name" message with the canonical name of the
+ command, for example "status" or "checkout".
+
+`void trace2_cmd_mode(const char *mode)`::
+
+ Emits a "cmd_mode" message with a qualifier name to further
+ describe the current git command.
++
+This message is intended to be used with git commands having multiple
+major modes. For example, a "checkout" command can checkout a new
+branch or it can checkout a single file, so the checkout code could
+emit a cmd_mode message of "branch" or "file".
+
+`void trace2_cmd_alias(const char *alias, const char **argv_expansion)`::
+
+ Emits an "alias" message containing the alias used and the
+ argument expansion.
+
+`void trace2_def_param(const char *parameter, const char *value)`::
+
+ Emits a "def_param" message containing a key/value pair.
++
+This message is intended to report some global aspect of the current
+command, such as a configuration setting or command line switch that
+significantly affects program performance or behavior, such as
+`core.abbrev`, `status.showUntrackedFiles`, or `--no-ahead-behind`.
+
+`void trace2_cmd_list_config()`::
+
+ Emits a "def_param" messages for "important" configuration
+ settings.
++
+The environment variable `GIT_TR2_CONFIG_PARAMS` can be set to a
+list of patterns of important configuration settings, for example:
+`core.*,remote.*.url`. This function will iterate over all config
+settings and emit a "def_param" message for each match.
+
+`void trace2_cmd_set_config(const char *key, const char *value)`::
+
+ Emits a "def_param" message for a specific configuration
+ setting IFF it matches the `GIT_TR2_CONFIG_PARAMS` pattern.
++
+This is used to hook into `git_config_set()` and catch any
+configuration changes and update a value previously reported by
+`trace2_cmd_list_config()`.
+
+`void trace2_def_repo(struct repository *repo)`::
+
+ Registers a repository with the Trace2 layer. Assigns a
+ unique "repo-id" to `repo->trace2_repo_id`.
++
+Emits a "worktree" messages containing the repo-id and the worktree
+pathname.
++
+Region and data messages (described later) may refer to this repo-id.
++
+The main/top-level repository will have repo-id value 1 (aka "r1").
++
+The repo-id field is in anticipation of future in-proc submodule
+repositories.
+
+=== Child Process Messages
+
+These are concerned with the various spawned child processes,
+including shell scripts, git commands, editors, pagers, and hooks.
+
+`void trace2_child_start(struct child_process *cmd)`::
+
+ Emits a "child_start" message containing the "child-id",
+ "child-argv", and "child-classification".
++
+Before calling this, set `cmd->trace2_child_class` to a name
+describing the type of child process, for example "editor".
++
+This function assigns a unique "child-id" to `cmd->trace2_child_id`.
+This field is used later during the "child_exit" message to associate
+it with the "child_start" message.
++
+This function should be called before spawning the child process.
+
+`void trace2_child_exit(struct child_proess *cmd, int child_exit_code)`::
+
+ Emits a "child_exit" message containing the "child-id",
+ the child's elapsed time and exit-code.
++
+The reported elapsed time includes the process creation overhead and
+time spend waiting for it to exit, so it may be slightly longer than
+the time reported by the child itself.
++
+This function should be called after reaping the child process.
+
+`int trace2_exec(const char *exe, const char **argv)`::
+
+ Emits a "exec" message containing the "exec-id" and the
+ argv of the new process.
++
+This function should be called before calling one of the `exec()`
+variants, such as `execvp()`.
++
+This function returns a unique "exec-id". This value is used later
+if the exec() fails and a "exec-result" message is necessary.
+
+`void trace2_exec_result(int exec_id, int error_code)`::
+
+ Emits a "exec_result" message containing the "exec-id"
+ and the error code.
++
+On Unix-based systems, `exec()` does not return if successful.
+This message is used to indicate that the `exec()` failed and
+that the current program is continuing.
+
+=== Git Thread Messages
+
+These messages are concerned with Git thread usage.
+
+`void trace2_thread_start(const char *thread_name)`::
+
+ Emits a "thread_start" message.
++
+The `thread_name` field should be a descriptive name, such as the
+unique name of the thread-proc. A unique "thread-id" will be added
+to the name to uniquely identify thread instances.
++
+Region and data messages (described later) may refer to this thread
+name.
++
+This function must be called by the thread-proc of the new thread
+(so that TLS data is properly initialized) and not by the caller
+of `pthread_create()`.
+
+`void trace2_thread_exit()`::
+
+ Emits a "thread_exit" message containing the thread name
+ and the thread elapsed time.
++
+This function must be called by the thread-proc before it returns
+(so that the coorect TLS data is used and cleaned up. It should
+not be called by the caller of `pthread_join()`.
+
+=== Region and Data Messages
+
+These are concerned with recording performance data
+over regions or spans of code.
+
+`void trace2_region_enter(const char *category, const char *label, const struct repository *repo)`::
+
+`void trace2_region_enter_printf(const char *category, const char *label, const struct repository *repo, const char *fmt, ...)`::
+
+`void trace2_region_enter_printf_va(const char *category, const char *label, const struct repository *repo, const char *fmt, va_list ap)`::
+
+ Emits a thread-relative "region_enter" message with optional
+ printf string.
++
+This function pushes a new region nesting stack level on the current
+thread and starts a clock for the new stack frame.
++
+The `category` field is an arbitrary category name used to classify
+regions by feature area, such as "status" or "index". At this time
+it is only just printed along with the rest of the message. It may
+be used in the future to filter messages.
++
+The `label` field is an arbitrary label used to describe the activity
+being started, such as "read_recursive" or "do_read_index".
++
+The `repo` field, if set, will be used to get the "repo-id", so that
+recursive oerations can be attributed to the correct repository.
+
+`void trace2_region_leave(const char *category, const char *label, const struct repository *repo)`::
+
+`void trace2_region_leave_printf(const char *category, const char *label, const struct repository *repo, const char *fmt, ...)`::
+
+`void trace2_region_leave_printf_va(const char *category, const char *label, const struct repository *repo, const char *fmt, va_list ap)`::
+
+ Emits a thread-relative "region_leave" message with optional
+ printf string.
++
+This function pops the region nesting stack on the current thread
+and reports the elapsed time of the stack frame.
++
+The `category`, `label`, and `repo` fields are the same as above.
+The `category` and `label` do not need to match the correpsonding
+"region_enter" message, but it makes the data stream easier to
+understand.
+
+`void trace2_data_string(const char *category, const struct repository *repo, const char *key, const char * value)`::
+
+`void trace2_data_intmax(const char *category, const struct repository *repo, const char *key, intmax value)`::
+
+`void trace2_data_json(const char *category, const struct repository *repo, const char *key, const struct json_writer *jw)`::
+
+ Emits a region- and thread-relative "data" or "data_json" message.
++
+This is a key/value pair message containing information about the
+current thread, region stack, and repository. This could be used
+to print the number of files in a directory during a multi-threaded
+recursive tree walk.
+
+`void trace2_printf(const char *fmt, ...)`::
+
+`void trace2_printf_va(const char *fmt, va_list ap)`::
+
+ Emits a region- and thread-relative "printf" message.
+
+== Trace2 Target Formats
+
+=== NORMAL Format
+
+NORMAL format is enabled when the `GIT_TR2` environment variable is
+set.
+
+Events are written as lines of the form:
+
+------------
+[<time> SP <filename>:<line> SP+] <event-name> [[SP] <event-message>] LF
+------------
+
+`<event-name>`::
+
+ is the event name.
+
+`<event-message>`::
+ is a free-form printf message intended for human consumption.
++
+Note that this may contain embedded LF or CRLF characters that are
+not escaped, so the event may spill across multiple lines.
+
+If `GIT_TR2_BRIEF` is true, the `time`, `filename`, and `line` fields
+are omitted.
+
+This target is intended to be more of a summary (like GIT_TRACE) and
+less detailed than the other targets. It ignores thread, region, and
+data messages, for example.
+
+=== PERF Format
+
+PERF format is enabled when the `GIT_TR2_PERF` environment variable
+is set.
+
+Events are written as lines of the form:
+
+------------
+[<time> SP <filename>:<line> SP+
+ BAR SP] d<depth> SP
+ BAR SP <thread-name> SP+
+ BAR SP <event-name> SP+
+ BAR SP [r<repo-id>] SP+
+ BAR SP [<t_abs>] SP+
+ BAR SP [<t_rel>] SP+
+ BAR SP [<category>] SP+
+ BAR SP DOTS* <perf-event-message>
+ LF
+------------
+
+`<depth>`::
+ is the git process depth. This is the number of parent
+ git processes. A top-level git command has depth value "d0".
+ A child of it has depth value "d1". A second level child
+ has depth value "d2" and so on.
+
+`<thread-name>`::
+ is a unique name for the thread. The primary thread
+ is called "main". Other thread names are of the form "th%d:%s"
+ and include a unique number and the name of the thread-proc.
+
+`<event-name>`::
+ is the event name.
+
+`<repo-id>`::
+ when present, is a number indicating the repository
+ in use. A `def_repo` event is emitted when a repository is
+ opened. This defines the repo-id and associated worktree.
+ Subsequent repo-specific events will reference this repo-id.
++
+Currently, this is always "r1" for the main repository.
+This field is in anticipation of in-proc submodules in the future.
+
+`<t_abs>`::
+ when present, is the absolute time in seconds since the
+ program started.
+
+`<t_rel>`::
+ when present, is time in seconds relative to the start of
+ the current region. For a thread-exit event, it is the elapsed
+ time of the thread.
+
+`<category>`::
+ is present on region and data events and is used to
+ indicate a broad category, such as "index" or "status".
+
+`<perf-event-message>`::
+ is a free-form printf message intended for human consumption.
+
+------------
+15:33:33.532712 wt-status.c:2310 | d0 | main | region_enter | r1 | 0.126064 | | status | label:print
+15:33:33.532712 wt-status.c:2331 | d0 | main | region_leave | r1 | 0.127568 | 0.001504 | status | label:print
+------------
+
+If `GIT_TR2_PERF_BRIEF` is true, the `time`, `file`, and `line`
+fields are omitted.
+
+------------
+d0 | main | region_leave | r1 | 0.011717 | 0.009122 | index | label:preload
+------------
+
+The PERF target is intended for interactive performance analysis
+during development and is quite noisy.
+
+=== EVENT Format
+
+EVENT format is enabled when the `GIT_TR2_EVENT` environment
+variable is set.
+
+Each event is a JSON-object containing multiple key/value pairs
+written as a single line and followed by a LF.
+
+------------
+'{' <key> ':' <value> [',' <key> ':' <value>]* '}' LF
+------------
+
+Some key/value pairs are common to all events and some are
+event-specific.
+
+==== Common Key/Value Pairs
+
+The following key/value pairs are common to all events:
+
+------------
+{
+ "event":"version",
+ "sid":"1547659722619736-11614",
+ "thread":"main",
+ "time":"2019-01-16 17:28:42.620713",
+ "file":"common-main.c",
+ "line":38,
+ ...
+}
+------------
+
+`"event":<event>`::
+ is the event name.
+
+`"sid":<sid>`::
+ is the session-id. This is a unique string to identify the
+ process instance to allow all events emitted by a process to
+ be identified. A session-id is used instead of a PID because
+ PIDs are recycled by the OS. For child git processes, the
+ session-id is prepended with the session-id of the parent git
+ process to allow parent-child relationships to be identified
+ during post-processing.
+
+`"thread":<thread>`::
+ is the thread name.
+
+`"time":<time>`::
+ is the UTC time of the event.
+
+`"file":<filename>`::
+ is source file generating the event.
+
+`"line":<line-number>`::
+ is the integer source line number generating the event.
+
+`"repo":<repo-id>`::
+ when present, is the integer repo-id as described previously.
+
+If `GIT_TR2_EVENT_BRIEF` is true, the `file` and `line` fields are omitted
+from all events and the `time` field is only present on the "start" and
+"atexit" events.
+
+==== Event-Specific Key/Value Pairs
+
+`"version"`::
+ This event gives the version of the executable and the EVENT format.
++
+------------
+{
+ "event":"version",
+ ...
+ "evt":"1", # EVENT format version
+ "exe":"2.20.1.155.g426c96fcdb" # git version
+}
+------------
+
+`"start"`::
+ This event contains the complete argv received by main().
++
+------------
+{
+ "event":"start",
+ ...
+ "argv":["git","version"]
+}
+------------
+
+`"exit"`::
+ This event is emitted when git calls `exit()`.
++
+------------
+{
+ "event":"exit",
+ ...
+ "t_abs":0.001227, # elapsed time in seconds
+ "code":0 # exit code
+}
+------------
+
+`"atexit"`::
+ This event is emitted by the Trace2 `atexit` routine during
+ final shutdown. It should be the last event emitted by the
+ process.
++
+(The elapsed time reported here is greater than the time reported in
+the "exit" event because it runs after all other atexit tasks have
+completed.)
++
+------------
+{
+ "event":"atexit",
+ ...
+ "t_abs":0.001227, # elapsed time in seconds
+ "code":0 # exit code
+}
+------------
+
+`"signal"`::
+ This event is emitted when the program is terminated by a user
+ signal. Depending on the platform, the signal event may
+ prevent the "atexit" event from being generated.
++
+------------
+{
+ "event":"signal",
+ ...
+ "t_abs":0.001227, # elapsed time in seconds
+ "signal":13 # SIGTERM, SIGINT, etc.
+}
+------------
+
+`"error"`::
+ This event is emitted when one of the `error()`, `die()`,
+ or `usage()` functions are called.
++
+------------
+{
+ "event":"error",
+ ...
+ "msg":"invalid option: --cahced", # formatted error message
+ "fmt":"invalid option: %s" # error format string
+}
+------------
++
+The error event may be emitted more than once. The format string
+allows post-processors to group errors by type without worrying
+about specific error arguments.
+
+`"cmd_path"`::
+ This event contains the discovered full path of the git
+ executable (on platforms that are configured to resolve it).
++
+------------
+{
+ "event":"cmd_path",
+ ...
+ "path":"C:/work/gfw/git.exe"
+}
+------------
+
+`"cmd_name"`::
+ This event contains the command name for this git process
+ and the hierarchy of commands from parent git processes.
++
+------------
+{
+ "event":"cmd_name",
+ ...
+ "name":"pack-objects",
+ "hierarchy":"push/pack-objects"
+}
+------------
++
+Normally, the "name" field contains the canonical name of the
+command. When a canonical name is not available, one of
+these special values are used:
++
+------------
+"_query_" # "git --html-path"
+"_run_dashed_" # when "git foo" tries to run "git-foo"
+"_run_shell_alias_" # alias expansion to a shell command
+"_run_git_alias_" # alias expansion to a git command
+"_usage_" # usage error
+------------
+
+`"cmd_mode"`::
+ This event, when present, describes the command variant This
+ event may be emitted more than once.
++
+------------
+{
+ "event":"cmd_mode",
+ ...
+ "name":"branch"
+}
+------------
++
+The "name" field is an arbitrary string to describe the command mode.
+For example, checkout can checkout a branch or an individual file.
+And these variations typically have different performance
+characteristics that are not comparable.
+
+`"alias"`::
+ This event is present when an alias is expanded.
++
+------------
+{
+ "event":"alias",
+ ...
+ "alias":"l", # registered alias
+ "argv":["log","--graph"] # alias expansion
+}
+------------
+
+`"child_start"`::
+ This event describes a child process that is about to be
+ spawned.
++
+------------
+{
+ "event":"child_start",
+ ...
+ "child_id":2,
+ "child_class":"?",
+ "use_shell":false,
+ "argv":["git","rev-list","--objects","--stdin","--not","--all","--quiet"]
+
+ "hook_name":"<hook_name>" # present when child_class is "hook"
+ "cd":"<path>" # present when cd is required
+}
+------------
++
+The "child_id" field can be used to match this child_start with the
+corresponding child_exit event.
++
+The "child_class" field is a rough classification, such as "editor",
+"pager", "transport/*", and "hook". Unclassified children are classified
+with "?".
+
+`"child_exit"`::
+ This event is generated after the current process has returned
+ from the waitpid() and collected the exit information from the
+ child.
++
+------------
+{
+ "event":"child_exit",
+ ...
+ "child_id":2,
+ "pid":14708, # child PID
+ "code":0, # child exit-code
+ "t_rel":0.110605 # observed run-time of child process
+}
+------------
++
+Note that the session-id of the child process is not available to
+the current/spawning process, so the child's PID is reported here as
+a hint for post-processing. (But it is only a hint because the child
+proces may be a shell script which doesn't have a session-id.)
++
+Note that the `t_rel` field contains the observed run time in seconds
+for the child process (starting before the fork/exec/spawn and
+stopping after the waitpid() and includes OS process creation overhead).
+So this time will be slightly larger than the atexit time reported by
+the child process itself.
+
+`"exec"`::
+ This event is generated before git attempts to `exec()`
+ another command rather than starting a child process.
++
+------------
+{
+ "event":"exec",
+ ...
+ "exec_id":0,
+ "exe":"git",
+ "argv":["foo", "bar"]
+}
+------------
++
+The "exec_id" field is a command-unique id and is only useful if the
+`exec()` fails and a corresponding exec_result event is generated.
+
+`"exec_result"`::
+ This event is generated if the `exec()` fails and control
+ returns to the current git command.
++
+------------
+{
+ "event":"exec_result",
+ ...
+ "exec_id":0,
+ "code":1 # error code (errno) from exec()
+}
+------------
+
+`"thread_start"`::
+ This event is generated when a thread is started. It is
+ generated from *within* the new thread's thread-proc (for TLS
+ reasons).
++
+------------
+{
+ "event":"thread_start",
+ ...
+ "thread":"th02:preload_thread" # thread name
+}
+------------
+
+`"thread_exit"`::
+ This event is generated when a thread exits. It is generated
+ from *within* the thread's thread-proc (for TLS reasons).
++
+------------
+{
+ "event":"thread_exit",
+ ...
+ "thread":"th02:preload_thread", # thread name
+ "t_rel":0.007328 # thread elapsed time
+}
+------------
+
+`"def_param"`::
+ This event is generated to log a global parameter.
++
+------------
+{
+ "event":"def_param",
+ ...
+ "param":"core.abbrev",
+ "value":"7"
+}
+------------
+
+`"def_repo"`::
+ This event defines a repo-id and associates it with the root
+ of the worktree.
++
+------------
+{
+ "event":"def_repo",
+ ...
+ "repo":1,
+ "worktree":"/Users/jeffhost/work/gfw"
+}
+------------
++
+As stated earlier, the repo-id is currently always 1, so there will
+only be one def_repo event. Later, if in-proc submodules are
+supported, a def_repo event should be emitted for each submodule
+visited.
+
+`"region_enter"`::
+ This event is generated when entering a region.
++
+------------
+{
+ "event":"region_enter",
+ ...
+ "repo":1, # optional
+ "nesting":1, # current region stack depth
+ "category":"index", # optional
+ "label":"do_read_index", # optional
+ "msg":".git/index" # optional
+}
+------------
++
+The `category` field may be used in a future enhancement to
+do category-based filtering.
++
+The `GIT_TR2_EVENT_NESTING` environment variable can be used to
+filter deeply nested regions and data events. It defaults to "2".
+
+`"region_leave"`::
+ This event is generated when leaving a region.
++
+------------
+{
+ "event":"region_leave",
+ ...
+ "repo":1, # optional
+ "t_rel":0.002876, # time spent in region in seconds
+ "nesting":1, # region stack depth
+ "category":"index", # optional
+ "label":"do_read_index", # optional
+ "msg":".git/index" # optional
+}
+------------
+
+`"data"`::
+ This event is generated to log a thread- and region-local
+ key/value pair.
++
+------------
+{
+ "event":"data",
+ ...
+ "repo":1, # optional
+ "t_abs":0.024107, # absolute elapsed time
+ "t_rel":0.001031, # elapsed time in region/thread
+ "nesting":2, # region stack depth
+ "category":"index",
+ "key":"read/cache_nr",
+ "value":"3552"
+}
+------------
++
+The "value" field may be an integer or a string.
+
+`"data-json"`::
+ This event is generated to log a pre-formatted JSON string
+ containing structured data.
++
+------------
+{
+ "event":"data_json",
+ ...
+ "repo":1, # optional
+ "t_abs":0.015905,
+ "t_rel":0.015905,
+ "nesting":1,
+ "category":"process",
+ "key":"windows/ancestry",
+ "value":["bash.exe","bash.exe"]
+}
+------------
+
+== Example Trace2 API Usage
+
+Here is a hypothetical usage of the Trace2 API showing the intended
+usage (without worrying about the actual Git details).
+
+Initialization::
+
+ Initialization happens in `main()`. Behind the scenes, an
+ `atexit` and `signal` handler are registered.
++
+----------------
+int main(int argc, const char **argv)
+{
+ int exit_code;
+
+ trace2_initialize();
+ trace2_cmd_start(argv);
+
+ exit_code = cmd_main(argc, argv);
+
+ trace2_cmd_exit(exit_code);
+
+ return exit_code;
+}
+----------------
+
+Command Details::
+
+ After the basics are established, additional command
+ information can be sent to Trace2 as it is discovered.
++
+----------------
+int cmd_checkout(int argc, const char **argv)
+{
+ trace2_cmd_name("checkout");
+ trace2_cmd_mode("branch");
+ trace2_def_repo(the_repository);
+
+ // emit "def_param" messages for "interesting" config settings.
+ trace2_cmd_list_config();
+
+ if (do_something())
+ trace2_cmd_error("Path '%s': cannot do something", path);
+
+ return 0;
+}
+----------------
+
+Child Processes::
+
+ Wrap code spawning child processes.
++
+----------------
+void run_child(...)
+{
+ int child_exit_code;
+ struct child_process cmd = CHILD_PROCESS_INIT;
+ ...
+ cmd.trace2_child_class = "editor";
+
+ trace2_child_start(&cmd);
+ child_exit_code = spawn_child_and_wait_for_it();
+ trace2_child_exit(&cmd, child_exit_code);
+}
+----------------
++
+For example, the following fetch command spawned ssh, index-pack,
+rev-list, and gc. This example also shows that fetch took
+5.199 seconds and of that 4.932 was in ssh.
++
+----------------
+$ export GIT_TR2_BRIEF=1
+$ export GIT_TR2=~/log.normal
+$ git fetch origin
+...
+----------------
++
+----------------
+$ cat ~/log.normal
+version 2.20.1.vfs.1.1.47.g534dbe1ad1
+start git fetch origin
+worktree /Users/jeffhost/work/gfw
+cmd_name fetch (fetch)
+child_start[0] ssh git@github.com ...
+child_start[1] git index-pack ...
+... (Trace2 events from child processes omitted)
+child_exit[1] pid:14707 code:0 elapsed:0.076353
+child_exit[0] pid:14706 code:0 elapsed:4.931869
+child_start[2] git rev-list ...
+... (Trace2 events from child process omitted)
+child_exit[2] pid:14708 code:0 elapsed:0.110605
+child_start[3] git gc --auto
+... (Trace2 events from child process omitted)
+child_exit[3] pid:14709 code:0 elapsed:0.006240
+exit elapsed:5.198503 code:0
+atexit elapsed:5.198541 code:0
+----------------
++
+When a git process is a (direct or indirect) child of another
+git process, it inherits Trace2 context information. This
+allows the child to print the command hierarchy. This example
+shows gc as child[3] of fetch. When the gc process reports
+its name as "gc", it also reports the hierarchy as "fetch/gc".
+(In this example, trace2 messages from the child process is
+indented for clarity.)
++
+----------------
+$ export GIT_TR2_BRIEF=1
+$ export GIT_TR2=~/log.normal
+$ git fetch origin

+exit elapsed:3.868938 code:0
+atexit elapsed:3.868970 code:0
+----------------
+
+Regions::
+
+ Regions can be use to time an interesting section of code.
++
+----------------
+void wt_status_collect(struct wt_status *s)
+{
+ trace2_region_enter("status", "worktrees", s->repo);
+ wt_status_collect_changes_worktree(s);
+ trace2_region_leave("status", "worktrees", s->repo);
+
+ trace2_region_enter("status", "index", s->repo);
+ wt_status_collect_changes_index(s);
+ trace2_region_leave("status", "index", s->repo);
+
+ trace2_region_enter("status", "untracked", s->repo);

+ trace2_region_enter("status", "print", s->repo);
+ switch (s->status_format) {
+ ...
+ }
+ trace2_region_leave("status", "print", s->repo);
+}
+----------------
++
+In this example, scanning for untracked files ran from +0.012568 to
++0.027149 (since the process started) and took 0.014581 seconds.

+Regions may be nested. This causes messages to be indented in the
+PERF target, for example.
+Elapsed times are relative to the start of the correpsonding nesting
+level as expected. For example, if we add region message to:
++
+----------------
+static enum path_treatment read_directory_recursive(struct dir_struct *dir,
+ struct index_state *istate, const char *base, int baselen,
+ struct untracked_cache_dir *untracked, int check_only,

+----------------
++
+We can further investigate the time spent scanning for untracked files.

+Trace2 regions are similar to the existing trace_performance_enter()
+and trace_performance_leave() routines, but are thread safe and
+maintain per-thread stacks of timers.
+
+Data Messages::
+
+ Data messages added to a region.
++
+----------------
+int read_index_from(struct index_state *istate, const char *path,
+ const char *gitdir)

+
+Thread Events::
+
+ Thread messages added to a thread-proc.
++
+For example, the multithreaded preload-index code can be
+instrumented with a region around the thread pool and then
+per-thread start and exit events within the threadproc.
++
+----------------
+static void *preload_thread(void *_data)
+{
+ // start the per-thread clock and emit a message.
+ trace2_thread_start("preload_thread");
+
+ // report which chunk of the array this thread was assigned.
+ trace2_data_intmax("index", the_repository, "offset", p->offset);
+ trace2_data_intmax("index", the_repository, "count", nr);
+
+ do {
+ ...
+ } while (--nr > 0);
+ ...
+
+ // report elapsed time taken by this thread.
+ trace2_thread_exit();
+ return NULL;
+}
+
+void preload_index(struct index_state *index,
+ const struct pathspec *pathspec,
+ unsigned int refresh_flags)

+ }
+
+ for (i = 0; i < threads; i++) {
+ ... /* join thread */
+ }
+
+ trace2_region_leave("index", "preload", the_repository);
+}
+----------------
++
+In this example preload_index() was executed by the `main` thread
+and started the `preload` region. Seven threads, named
+`th01:preload_thread` through `th07:preload_thread`, were started.
+Events from each thread are atomically appended to the shared target
+stream as they occur so they may appear in random order with respect
+other threads. Finally, the main thread waits for the threads to
+finish and leaves the region.
++
+Data events are tagged with the active thread name. They are used
+to report the per-thread parameters.

+In this example, the preload region took 0.009122 seconds. The 7 threads
+took between 0.006069 and 0.008947 seconds to work on their portion of
+the index. Thread "th01" worked on 508 items at offset 0. Thread "th02"
+worked on 508 items at offset 2032. Thread "th04" worked on 508 itemts
+at offset 508.
++
+This example also shows that thread names are assigned in a racy manner
+as each thread starts and allocates TLS storage.
+
+== Future Work
+
+=== Relationship to the Existing Trace Api (api-trace.txt)
+
+There are a few issues to resolve before we can completely
+switch to Trace2.
+
+* Updating existing tests that assume GIT_TRACE format messages.
+
+* How to best handle custom GIT_TRACE_<key> messages?
+
+** The GIT_TRACE_<key> mechanism allows each <key> to write to a
+different file (in addition to just stderr).
+
+** Do we want to maintain that ability or simply write to the existing
+Trace2 targets (and convert <key> to a "category").
* one side of history renames x -> z, and the other renames some file to
x/e, causing the need for the merge to do a transitive rename.
- * one side of history renames x -> z, but also renames all files within
- x. For example, x/a -> z/alpha, x/b -> z/bravo, etc.
+ * one side of history renames x -> z, but also renames all files within x.
+ For example, x/a -> z/alpha, x/b -> z/bravo, etc.
* both 'x' and 'y' being merged into a single directory 'z', with a
directory rename being detected for both x->z and y->z.
An example client/server communication might look like this:

Git Protocol Capabilities
=========================
+NOTE: this document describes capabilities for versions 0 and 1 of the pack
+protocol. For version 2, please refer to the link:protocol-v2.html[protocol-v2]
+doc.
+
Servers SHOULD support all capabilities defined in this document.
On the very first line of the initial server response of either
purposes, and MUST NOT be used to programmatically assume the presence
or absence of particular features.
+symref
+------
+
+This parameterized capability is used to inform the receiver which symbolic ref
+points to which ref; for example, "symref=HEAD:refs/heads/master" tells the
+receiver that HEAD points to master. This capability can be repeated to
+represent multiple symrefs.
+
+Servers SHOULD include this capability for the HEAD symref if it is one of the
+refs being sent.
+
+Clients MAY use the parameters from this capability to select the proper initial
+branch when cloning a repository.

- Git Wire Protocol, Version 2
-==============================
+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:
has completed, a client can reuse the connection and request that other
commands be executed.
- Packet-Line Framing
----------------------
+Packet-Line Framing
+-------------------
All communication is done using packet-line framing, just as in v1. See
`Documentation/technical/pack-protocol.txt` and
* '0000' Flush Packet (flush-pkt) - indicates the end of a message
* '0001' Delimiter Packet (delim-pkt) - separates sections of a message
- Initial Client Request
-------------------------
+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
found in `pack-protocol.txt` and `http-protocol.txt`. In all cases the
response from the server is the capability advertisement.
- Git Transport
-~~~~~~~~~~~~~~~
+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
-~~~~~~~~~~~~~~~~~~~~~~~~
+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
-~~~~~~~~~~~~~~~~
+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
Subsequent requests are then made directly to the service
`$GIT_URL/git-upload-pack`. (This works the same for git-receive-pack).
- Capability Advertisement
---------------------------
+Capability Advertisement
+------------------------
A server which decides to communicate (based on a request from a client)
using protocol version 2, notifies the client by sending a version string
key = 1*(ALPHA | DIGIT | "-_")
value = 1*(ALPHA | DIGIT | " -_.,?\/{}[]()<>!@#$%^&*+=:;")
- Command Request
------------------
+Command Request
+---------------
After receiving the capability advertisement, a client can then issue a
request to select the command it wants with any particular capabilities
optionally send an empty request consisting of just a flush-pkt to
indicate that no more requests will be made.
- Capabilities
---------------
+Capabilities
+------------
There are two different types of capabilities: normal capabilities,
which can be used to to convey information or alter the behavior of a
permits simple round-robin load-balancing on the server side, without
needing to worry about state management.
- agent
-~~~~~~~
+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
and debugging purposes, and MUST NOT be used to programmatically assume
the presence or absence of particular features.
- ls-refs
-~~~~~~~~~
+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
symref = "symref-target:" symref-target
peeled = "peeled:" obj-id
- fetch
-~~~~~~~
+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
2 - progress messages
3 - fatal error message just before stream aborts
- server-option
-~~~~~~~~~~~~~~~
+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
where <address> may be a path, a server and path, or an arbitrary
URL-like string recognized by the specific remote helper being
-invoked. See linkgit:gitremote-helpers[1] for details.

+ precedence: the value of the GIT_TEST_STRESS_LOAD
environment variable, or twice the number of available
processors (as shown by the 'getconf' utility), or 8.
Implies `--verbose -x --immediate` to get the most information
'.stress-<nr>' suffix, and the trash directory of the failed
test job is renamed to end with a '.stress-failed' suffix.

--stress-limit=<N>::
When combined with --stress run the test script repeatedly
this many times in each of the parallel jobs or until one of

+ them fails, whichever comes first. Implies `--stress`.
You can also set the GIT_TEST_INSTALLED environment variable to
the bindir of an existing git installation to test that installation.
GIT_TEST_SPLIT_INDEX=<boolean> forces split-index mode on the whole
test suite. Accept any boolean values that are accepted by git-config.
+GIT_TEST_PROTOCOL_VERSION=<n>, when set, overrides the
+'protocol.version' setting to n if it is less than n.

GIT_TEST_FULL_IN_PACK_ARRAY=<boolean> exercises the uncommon
pack-objects code path where there are more than 1024 packs even if
the actual number of packs in repository is below this limit. Accept
GIT_TEST_PRELOAD_INDEX=<boolean> exercises the preload-index code path
by overriding the minimum number of cache entries required per thread.

+
+ Prepend <script> to a list of commands to run unconditionally to
+ clean up before the test script exits, e.g. to stop a daemon:
+
+ test_expect_success 'test git daemon' '
+ git daemon &
+ daemon_pid=$! &&
+ test_atexit 'kill $daemon_pid' &&
+ hello world
+ '
+
+ The commands will be executed before the trash directory is removed,
+ i.e. the atexit commands will still be able to access any pidfiles or
+ socket files.
+
+ Note that these commands will be run even when a test script run
+ with '--immediate' fails. Be careful with your atexit commands to
+ minimize any changes to the failed state.
+
- test_write_lines <lines>
Write <lines> on standard output, one line per argument.
test_oid_init or test_oid_cache. Providing an unknown key is an
error.
+ - yes [<string>]
+
+ This is often seen in modern UNIX but some platforms lack it, so
+ the test harness overrides the platform implementation with a
+ more limited one. Use this only when feeding a handful lines of
+ output to the downstream---unlike the real version, it generates
+ only up to 99 lines.

+
+In order to test git-pack-redundant, we will create a number of objects and
+packs in the repository `master.git`. The relationship between packs (P1-P8)
+and objects (T, A-R) is showed in the following chart. Objects of a pack will
+be marked with letter x, while objects of redundant packs will be marked with
+exclamation point, and redundant pack itself will be marked with asterisk.
