In this large session, I'm certainly not seeing hangs of a few seconds, and a full GC also takes about 3 seconds. Are you using the standard generation chain?

Good catch! The wrapping on overflow looks problematic.

Does MPS make a distinction between full collection and "normal"
collections? Are those somehow non-incremental?
It could be that MPS decides to start a full trace, but it advances the
trace only while (now < intervalEnd).
If "full collections" are just like normnal collections, then I see no
particular reason why starting full traces should be discouraged.
(My guess is that the slowness has something to do with intervals, but I
have zero evidence for that.)

Magit enables auto-revert by default: Bad idea, IMO. At least as long as file notifications are used: those don't scale well.

Hmm. Yes, I do. Because `magit-auto-revert-mode' (enabled by default).
I explicitly disable global-auto-revert-mode in my config.

It completely removes the hangs.

Well. Magit enables auto-revert by default:
(define-globalized-minor-mode magit-auto-revert-mode auto-revert-mode
magit-turn-on-auto-revert-mode-if-desired
:package-version '(magit . "2.4.0")
:link '(info-link "(magit)Automatic Reverting of File-Visiting Buffers")
:group 'magit-auto-revert
:group 'magit-essentials
;; - When `global-auto-revert-mode' is enabled, then this mode is
;; redundant.
;; - In all other cases enable the mode because if buffers are not
;; automatically reverted that would make many very common tasks
;; much more cumbersome.
:init-value (not (or global-auto-revert-mode
noninteractive)))

Setting it to 0 makes hangs somewhat shorter, but they are still there.
Setting it to 0.0 does not change anything.

This seems like an IGC bug for very unusual MPS parameters, which we
use. (I hesitate to call it an MPS bug, but the documentation could be
clearer here).
The relevant code is ArenaStep in global.c:
Bool ArenaStep(Globals globals, double interval, double multiplier)
{
Bool workWasDone =3D FALSE;
Clock start, intervalEnd, availableEnd, now;
start =3D now =3D ClockNow();
intervalEnd =3D start + (Clock)(interval * (double)clocks_per_sec);
availableEnd =3D start + (Clock)(interval * multiplier * (double)clocks_p=
er_sec);
/* loop while there is work to do and time on the clock. */
do {
Trace trace;
if (arena->busyTraces !=3D TraceSetEMPTY) {
trace =3D ArenaTrace(arena, (TraceId)0);
/* falls through */
} else {
/* No traces are running: consider collecting the world. */
if (PolicyShouldCollectWorld(arena, (double)(availableEnd - now), now=
,
clocks_per_sec))
{
Res res;
res =3D TraceStartCollectAll(&trace, arena, TraceStartWhyOPPORTUNIS=
M);
if (res !=3D ResOK)
break;
arena->lastWorldCollect =3D now;
} else {
/* Not worth collecting the world; consider starting a trace. */
Bool worldCollected;
if (!PolicyStartTrace(&trace, &worldCollected, arena, FALSE))
break;
}
}
TraceAdvance(trace);
if (trace->state =3D=3D TraceFINISHED)
TraceDestroyFinished(trace);
workWasDone =3D TRUE;
now =3D ClockNow();
} while (now < intervalEnd);
...
}
We call this code with multiplier =3D 0. It looks to me like the lowest
useful value for multiplier is 1.0.
The problem, I think, is that the do { ... } while () loop runs (at
least) twice: the first time, a busy trace finishes, the code falls
through, "now" is reset to the *current* clock, which makes
(availableEnd - now) "negative". But as the types are both unsigned,
the "negative" value will correspond to a large Clock value, which will
make MPS reach the conclusion it's a good time to start a full
collection.
I think the intention was for "multiplier" in the above code always to
be at least 1.0. The documentation isn't quite clear on what
"multiplier" is supposed to be set to, particularly in our case where we
want to discourage full collections. 1.0 seems to be the lowest safe
value, so let's use that?
> Opportunism: client predicts plenty of idle time, so start full collectio=
n.
Two full collections would cause a significant slow-down, yes.
If you want to continue testing before this is fixed, please consider
setting igc-step-interval to 0 (the fixnum, not the float) or 0.0 (which
has different behavior because we have a do { ... } while (...) loop).
Does that analysis make sense?

You mean, Emacs has this approximate memory footprint as soon as you start a fresh session? Can you start the cpu profiler just before you run project-compile, and then show the profile (assuming the profiler doesn't cause crashes on the branch in your build)?

A couple more questions:
. what is the memory footprint (resident and VM total) of the Emacs
process when this happens?
. do you see any signs of paging (significant disk activity) when
those "hangs" happen?

Many! First, may I ask you to save a core file (attach gdb, "gcore", shouldn't destroy the session) somewhere along with the emacs binary and .pdmp file that correspond to it? That way, if we fix your session we can still figure out why it was broken in the first place. (Of course, you should nevershare the core file). The next step would be to set garbage-collection-messages to t to see whether it's indeed MPS that's to blame. What are the values of igc-step-interval and igc--balance-intervals? Can you send a dump of the output of M-x igc-stats and M-x igc-roots-stats? Does a manual full collection (M-x igc-collect) help temporarily? How long does it take? Are you using the debug version of libmps or the standard version? IIUC, the debug version sometimes verifies so many things that it runs into complexity issues. Attaching gdb Monte-Carlo-style a few times during the hang and sending the "bt full" might also provide some hints. > In GNU Emacs 31.0.50 (build 2, x86_64-pc-linux-gnu, GTK+ Version > 3.24.42, cairo version 1.18.2) of 2025-02-15 built on localhost > Repository revision: 67e602105774a31508239a6d2a6a05a4d4c5d363 Hmm.

Hi,
After running Emacs for a few days (no crashes!), I noticed significant
hangs when running compilation.
The perf data is silent, but Emacs becomes unresponsive right at the
beginning of compilations and sometimes in the middle, as the
compilation buffer is filled.
Any suggestions, ideas?
