Hi!

I use Emacs on Mac OS X, Mavericks, Intel MacBook Pro, downloaded from emacsformacosx.com.

Running Emacs, a process named "distnoted" starts around 1% or 2% of the CPU, and after a while, slowly works its way up to 50% to 100% of the CPU.  Yoiks!  Actually there appear to be 3 distnoted processes, but only one eats up the CPU.

Quitting Emacs brings distnoted down to under 1% within seconds.

Just want to add that I have the same problem.  After quitting emacs
the distnoted process quiets  down to an acceptable level.

Hello. 

I can not reproduce this. Does it happen when you start with -Q and then do nothing else?  I tried with trunk and downloaded binaries from the site (release and latest).  I ran them on two computers with 10.9. I once managed to get a distnoted process to use 1.2 percent CPU, but otherwise they where steady at 0 - 0.3 % no matter what I did in Emacs. I monitored the trunk build for a whole workday, about 8 hours.

I too have this problem. I'm not quite sure what triggers it, but it
seems to to have something to do with command-tabbing (or at least
that's what it feels like).

If I can pinpoint it exactly I'll let it know.

Just wanted to bump this up, as I've now seen this bug myself. Not sure
why Emacs is causing the problem. My emacs was built from macports.

Which "port" did you use to build Emacs from MacPorts?

I'm asking it because I'd like to know if this problem can also happen
with Emacs Mac port(*).  Users of the MacPorts package system can use
it via the "port" named "emacs-mac-app" (its application bundle name
is EmacsMac.app).

It is no use bumping anything that isn't reproducable. More helpful would be if those that have this can do some debugging. For example dtruss on Emacs and distnoted.

Hello, I've investigated this problem since I had similar symptoms
that correlated with everyone else's reports (quit emacs.app and
distnoted quiets down). Also, in my case when I download the vanilla
emacs.app from the emacs for OSX site, the problem does not appear. In
my case, under Mavericks, this problem only occurs when I use
Emacs.app with the inline patch applied (for more native Japanese
input).

Emacs inline patch
http://svn.sourceforge.jp/svnroot/macemacsjp/inline_patch/trunk/emacs-inline.patch

After investigating, it seems that the purpose of distnoted is to
serve as a daemon to facilitate interapplication communication. In the
case of the "inline patch", to capture the moment the IME is changed
so that Emacs can do likewise to change language input. This is done
by adding an observer using NSDistributedNotificationCenter and there
is also a corresponding Core Foundation method. I didn't find any used
of NSDistributedNotificationCenter in the official release (24.3)
source.

https://developer.apple.com/library/mac/documentation/cocoa/reference/foundation/classes/NSDistributedNotificationCenter_Class/Reference/Reference.html

The fix was to add
"suspensionBehavior:NSNotificationSuspensionBehaviorDeliverImmediately"
rather than the default which was
"NSNotificationSuspensionBehaviorCoalesce". For whatever reason,
modifying the inline patch in this manner fixed the issue for me. This
would be consistent with the report above that "Cmd Tabbing" seems to
trigger it (since it would activate the suspension behavior).

Others with the same problem seem to take a sledgehammer approach of
killing distnoted with a cronjob (which I did manually as well).

This is the patch (modified by hand so it may not apply) against emacs 24.3.

https://gist.github.com/anonymous/8142555

The modified line:

  [[NSDistributedNotificationCenter defaultCenter] addObserver: NSApp
                    selector: @selector (changeInputMethod:)
                           name:
@"AppleSelectedInputSourcesChangedNotification" object: nil
suspensionBehavior:NSNotificationSuspensionBehaviorDeliverImmediately];

Suspension Behavior
https://developer.apple.com/library/mac/documentation/cocoa/reference/foundation/classes/NSDistributedNotificationCenter_Class/Reference/Reference.html#//apple_ref/doc/c_ref/NSNotificationSuspensionBehavior

For others who do not use the patch, there may be other applications,
since this is most likely a bug with Mavericks itself and you may want
to log distnoted for additional hints and grep the source of your
emacs build to see if NSDistributedNotificationCenter is being used.

Logging Distnoted

Hope this helps someone.

Hello.

This is good to know, but others said they used Emacs downloaded from emacsformacosx.com, which is supposed to be unpatched.  So there might be more than one reason for this.

It does appear to be entirely unpatched, and the tools to produce
it are publicly available[0] so it's easy to check.  There's also
an archive[1] of releases, pretests, and nightlies going back to
2006 (!) in .dmg format which is sometimes handy for bisection.

This has to be done by someone who has the problem.  I already tried several of their builds, on three separate machines.  None exhibit the problem.

I have been observing this since Mavericks was released. I did not make a
connection between distnoted and emacs, other than the following
observation: both are leaking memory.

For the first time ever I am finding that my emacs process slowly grows in
size. I can be editing a small handful of files and be using 500Mb of real
memory. Never seen that before, ever.

Distnoted grows much faster, on the order of 1Gb real memory / day. Killing
that process and having another start up automatically causes some OS X
features to stop working, e.g., it is not possible to enter Time Machine or
even see the status of your Time Machine backups anymore.

I have seen distnoted peg the CPU when Time Machine backups are running or
recently completed. Meanwhile, the menubar no longer animates the
in-progress backup, which I assume is not on purpose and possibly even
related to the issue.

I do not use shells in emacs nowadays.

I am running emacs from emacsformacosx.

I have filed bugs with Apple.

If anybody has any suggestions on how to figure out what is causing Emacs to
grow in size, I will happily run some experiments for you. I tried to figure
out how to profile emacs memory but it was not very obvious to me what to
do.

I think that is so OSX can save a bit of power.

The obvious thing is to run leaks on Emacs (man leaks) after a garbage collection has been made (M-x garbage-collect).  Leaks may report leaks which in fact are not due to uncollected garbage.

This is what I see if I run the "leaks" program on my Mac on the emacs process:

Leak: 0x1109f7b20  size=160  zone: DefaultMallocZone_0x100659000   OS_dispatch_source  ObjC  libdispatch.dylib

A bazillion of them.

I also ran it on a distnoted which I just killed and restarted because the existing one was over 2Gb of real memory (or so it said). It claimed there were no leaks.

This leaks program is pretty cool. It's like a conservative GC algorithm that assumes every integer could be a pointer. So by definition is is conservative.

Anyway - does this piece of information help any smart hacker types?

I've fired up Emacs with the -q and -nsl options. So my .emacs is not loaded and neither is the site-lisp. It starts leaking memory at a rate ... well here you go:

$ while true
> do
> sudo leaks 12095 | head -20 | grep "leaks for"
> sleep 1
> done
Process 12095: 935 leaks for 165824 total leaked bytes.
Process 12095: 954 leaks for 168864 total leaked bytes.
Process 12095: 972 leaks for 171744 total leaked bytes.
Process 12095: 986 leaks for 173984 total leaked bytes.
Process 12095: 1005 leaks for 177024 total leaked bytes.
Process 12095: 1025 leaks for 180224 total leaked bytes.
Process 12095: 1039 leaks for 182464 total leaked bytes.
Process 12095: 1057 leaks for 185344 total leaked bytes.
Process 12095: 1076 leaks for 188384 total leaked bytes.
Process 12095: 1090 leaks for 190624 total leaked bytes.
Process 12095: 1107 leaks for 193344 total leaked bytes.
Process 12095: 1127 leaks for 196544 total leaked bytes.
Process 12095: 1147 leaks for 199744 total leaked bytes.
Process 12095: 1158 leaks for 201504 total leaked bytes.
Process 12095: 1178 leaks for 204704 total leaked bytes.
Process 12095: 1195 leaks for 207424 total leaked bytes.
Process 12095: 1209 leaks for 209664 total leaked bytes.

So it's basically something like 20 individual 160 byte leaks per second. If I actually use emacs it seems to have spurts of many more leaks. These do seem like proper leaks because my emacs memory is growing at the same rate as this leaks is reporting, and, I am literally running an emacs with nothing in it and not interacting with it.

This is grasping at straws at its worst.

It'd be useful to state precisely which Emacs you're running.

Sorry about that!

	GNU Emacs 24.3.1 (x86_64-apple-darwin, NS apple-appkit-1038.36) of 2013-03-13 on bob.porkrind.org

From emacsformacos.com.

I think I was already using this version before I upgraded to Mavericks and it was sometime after the Mavericks upgrade that I noticed the leak. So it's ... likely an incompatible change or just a bug in Mavericks.

You should try a newer version, built from the trunk.

They are not all like that, somewhere in there is the real leak.  You need to save all output, and put it somewhere it can be read.  If it is large, better not send it to the list.
But if you are doing this, do it on a more recent version than 24.3.

Trunk Emacs seems okay, I get a much smaller output from leaks. There
are some leaks in there that I think are worth a look though, see
attached.

I just downloaded Emacs for OS X does and it defiantly has a problem with
leaking, a freshly started Emacs already generates over a MB of output
with leaks.

Don't do that unless you are attaching something big.

I forgot, you should start your Emacs like this:

and then run leaks.  It will then print a stack trace also.  This may slow Emacs down a bit.

Can you run this again, but with MallocStackLogging set?  I.e.:

% MallocStackLogging=1 .../path/to/Emacs.app/Contents/MacOS/Emacs

And if you can, briefly describe what you did in Emacs before running
leaks.

Thanks,

Sure, see [1].

I simply did C-h v font-lock <TAB> to bring up a completion buffer, then
added -keywords <RET> to bring up the help buffer and followed the
reference to font-lock.el. That seemed to cause the leaks.

I have downloaded the nightly and my problem is solved. Neither distnoted nor emacs is leaking anymore.

Well - ok there is apparently one leak occurring in emacs. It looks sort of like a string with a regular expression in it:

So, I think this was caused by turning on flyspell-mode. The size is 16k which just reeks of two 8k buffers associated with a pipe or something.

Thanks for all the help with this issue.

Hi,

Just one thing I noticed, whenever the system is in "leak mode" between
distnoted and emacs: one way to trigger a CPU use spike is to change ambient
light level (say by covering the sensor with your hand). Might be useful in
reproducing / tracing whatever is happening in distnoted ...

(using GNU Emacs 24.3.50.1 from homebrew)

I had downloaded a nightly and was so happy to see that the memory leak was
gone. However, the nightly has a ton of other problems with a package that
is near and dear to my heart at the moment: mumamo.

So I have downloaded the source and compiled it and tried to patch it with
the suggestion involving a patch early in this bug report, but that has not
solved the problem. Then I remembered that I could get stack traces, which I
have done:

The last line of code in emacs that produces this leak is:

      if (++apploopnr != 1)
        {
          emacs_abort ();
        }
      [NSApp run];
      --apploopnr;

well it's the --apploopnr according to leaks! A little weird if you ask me.

Anyway - does anybody have any insights into this?

You are better off trying to get mumamo working with trunk.  There are so many differences between 24.3 and trunk.  It is no trivial task to identify which has memory leak fixes.

The stack trace clearly states that it is in NSApp run (i.e. NSApplication run), so the trace is off by one line.  This happens often.

Date: Mon, 20 Jan 2014 18:53:52 +0900

After reading reports in this thread that it was fixed in the trunk I
went and applied the aforementioned inline patch to the current trunk
and indeed the distnoted issue seems fixed. Whereas with my patch to
the inline patch the problem seemed a little more tolerable and still
required occasionally killing distnoted (and Emacs.app crashed
although less frequently).

If there is a single commit that can make distnoted behave, it may be
in the interest of others using Mavericks to have this incorporated
into an official point release and close this bug (the distnoted bug
for those affected can be quite severe, locking up the entire machine
in my case). Mavericks is inevitable for many mac users and some
people may not be ready to transition to 24.4 for whatever reasons.

The modified inline patch (only relevant if you use Japanese or some
other language for writing text in Emacs and want seamless language
switching while using various keys/commands) for the current trunk:

There will not be any release for the 24.3 branch.  24.4 is next.

The patch is way too big to be incorporated into Emacs in the current feature freeze.

Subject: a patch against emacs 24.3.1 for fixing the distnoted memory leak
Date: Mon, 20 Jan 2014 12:01:30 +0000

This is FYI for people who do not want to wait for emacs 24.4 and cannot use one of the current nightlies to get around the Mavericks distnoted issue.

I am not a Mac programmer unfortunately, so take this with a grain of salt. My analysis of the problem is this:

1) When Mavericks came out a memory leak was discovered and fixed by Jan D. who is a frequent contributor to ns (Next Step) emacs for Mac OS X.

2) His fix, I think, was to avoid calling Application.run 20 times / second by introducing a variable called "shouldKeepRunning" into the Application.run method.

3) Repeatedly calling Application.run was causing a 160 byte leak each time inside emacs. But I think it was also causing a problem with distnoted, and I am speculating (knowing NOTHING ABOUT IT) that each call to run() was causing some sort of registration with distnoted. That registration, I assume, creates some sort of context in distnoted that is substantially larger than 160 bytes. So the leak in emacs was relatively slow, the one in distnoted was much larger.

This would also explain why distnoted would get slower as time goes by because it has hundreds of thousands of registrations, all for emacs, which I assume it was still trying to deliver notifications to, but really, I have no idea what I am talking about.

So, I applied part of Jan D's patch to emacs-24.3 that addressed this particular problem, and presto-chango, the leak is gone, distnoted is happy, and all my current elisp packages work because it's still emacs-24.3 and not emacs-24.4 which I assume is what's being created in the trunk today.

So - should I post this particular patch some place? Are other people interested in having this patch?

Great detective work. I'd like to see the patch! ;)

Even if it's superseded by the next release (24.4), some people might
be stuck on 24.3 for whatever reason and right now this bug thread is
the best reference for information.

In the mean time, some more experienced people can look at the patch
and further isolate the relevant changes for a tighter patch or
confirm your work. People with the bug can build with your patch and
confirm whether this bug is fixed by it too.

Is this still a problem on Mavericks with Emacs 25?

No response in 29 weeks, I think we can close this one.

Yes, this was fixed long ago.  I've been using the builds from emacsformacosx.com and the problem has not recurred.

And thanks, 'great job, it's appreciated.
