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.
