-
-Thread execution context (thread_exec_ctx) is a combination of type and pointer
-that are set in the current running thread at th_ctx->exec_ctx when entering
-certain processing (tasks, sample fetch functions, actions, CLI keywords etc).
-They're refined along execution, so that a task such as process_stream could
-temporarily switch to a converter while evaluating an expression and switch
-back to process_stream. They are reported in thread dumps and are mixed with
-caller locations for memory profiling. As such they are intentionally not too
-precise in order to avoid an explosion of the number of buckets. At the moment,
-the level of granularity it provides is sufficient to try to narrow a
-misbehaving origin down to a list of keywords. The context types can currently
-be:
-
-- something registered via an initcall, with the initcall's location
-- something registered via an ha_caller, with the caller's location
-- an explicit sample fetch / converter / action / CLI keyword list
-- an explicit function (mainly used for actions without keywords)
-- a task / tasklet (no distinction is made), using the ->process pointer
-- a filter (e.g. compression), via flt_conf, reporting name
-- a mux (via the mux_ops, reporting the name)
-- an applet (e.g. cache, stats, CLI)
-
-A macro EXEC_CTX_MAKE(type, pointer) makes a thread_exec_ctx from such
-values.
-
-A macro EXEC_CTX_NO_RET(ctx, statement) calls a void statement under the
-specified context.
-
-A macro EXEC_CTX_WITH_RET(ctx, expr) calls an expression under the specified
-context.
-
-Most locations were modified to directly use these macros on the fly, by
-retrieving the context from where it was set on the element being evaluated
-(e.g. an action rule contains the context inherited by the action keyword
-that was used to create it).
-
-In tools.c, chunk_append_thread_ctx() tries to decode the given exec_ctx and
-appends it into the provided buffer. It's used by ha_thread_dump_one() and
-cli_io_handler_show_activity() for memory profiling. In this latter case,
-the detected thread_ctx are reported in the output under brackets prefixed
-with "[via ...]" to distinguish call paths to the same allocators.
-
-A good way to test if a context is properly reported is to place a bleeding
-malloc() call into one of the monitored functions, e.g.:
-
-   DISGUISE(malloc(8));
-
-and issue "show profiling memory" after stressing the function. Its context
-must appear on the right with the number of calls.
