Subject: [PATCH v8 0/7] progress: test fixes / cleanup
Date: Tue, 28 Dec 2021 16:18:56 +0100 [thread overview]
Message-ID: <cover-v8-0.7-00000000000-20211228T150728Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v6-0.6-00000000000-20211228T143223Z-avarab@gmail.com>
Various test, leak and other fixes for the progress.c code and its
tests. This v8 addresses feedback on v7[1] by Johannes
Altmanninger. For that round I accidentally broke the In-Reply-To
chain, so I'm replying to the v6 here to attach it to the original
thread again.

## Commit message ##
progress.c: add temporary variable from progress struct
- Add a temporary "progress" variable for the dereferenced p_progress
- pointer to a "struct progress *". Before 98a13647408 (trace2: log
- progress time and throughput, 2020-05-12) we didn't dereference
- "p_progress" in this function, now that we do it's easier to read the
- code if we work with a "progress" struct pointer like everywhere else,
- instead of a pointer to a pointer.
+ Since 98a13647408 (trace2: log progress time and throughput,
+ 2020-05-12) stop_progress() dereferences a "struct progress **"
+ parameter in several places. Extract a dereferenced variable (like in
+ stop_progress_msg()) to reduce clutter and make it clearer who needs
+ to write to this parameter.
+
+ Now instead of using "*p_progress" several times in stop_progress() we
+ check it once for NULL and then use a dereferenced "progress" variable
+ thereafter. This continues the same pattern used in the above
+ stop_progress() function, see ac900fddb7f (progress: don't dereference
+ before checking for NULL, 2020-08-10).

@@ Commit message
reached the early exit in this function.
We could call stop_progress() before we return, but better yet is to
- defer calling start_progress() until we need it.
-
- This will matter in a subsequent commit where we BUG(...) out if this
- happens, and matters now e.g. because we don't have a corresponding
- "region_end" for the progress trace2 event.
+ defer calling start_progress() until we need it. For now this only
+ matters in practice because we'd previously omit the "region_leave"
+ for the progress trace2 event.
