are you absolutely sure that will cause it to be initialized on the first call, not as a global ctor?

it should be although I'm not sure why that would matter, personally I like the variable being local to the one function we use it in.

Absolutely sure.

But although it will save a couple of source code lines, the final binary will be several bytes larger than the patch here, because the compiler has to do the job for us.

I'm OK with either approach.

[Chris Coulson (chrisccoulson)]

On Linux, the glib slice allocator is disabled in |XREMain::XRE_main| by calling |g_slice_set_config| (see bug 431221). However, this no longer works since glib 2.35 because libgobject (which libxul depends on) now has a static initializer which indirectly initializes the slice allocator before |main| is reached (in order to automatically initialize the gobject dynamic type system). This means that the call to g_slice_set_config always fails with the following assertion:

(process:24722): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed

See https://bugzilla.gnome.org/show_bug.cgi?id=687763

[Alan Robertson (alanr-unix)]

Thunderbird doesn't start AT ALL in kubuntu 13.04. because of this bug. Or rather, it starts, but the part of it that opens a display window doesn't start. If I log in with web mail I see that it is filing emails as they arrive according to the rules I've established -- but the display never comes up.

And, in this particular case, I could have been completely unable to report this bug - because you forced me to change my password -- and sent me an email so I could do it :-D. Of course, since Thunderbird isn't working -- it became more challenging...

Strangely enough, Firefox _does_ start.

[Alan Robertson (alanr-unix)]

Following the link to the gnome bugzilla -- I ran across a tolerable workaround for the moment: If G_SLICE=always-malloc is in the environment, then it will start. It still complains, but it starts and appears to work (so far).

This makes it consume more CPU (and Lord knows it already consumes enough CPU), but it does allow Thunderbird to start - which is a good thing.

[P-nikolic1 (p-nikolic1)]

That's not what the glib code suggests. That error (sys_page_size == 0) happens because the slice allocator is *not* initialized. If it was initialized, sys_page_size would be set (it is set in g_slice_init_nomessage).

[Chris Coulson (chrisccoulson)]

Isn't that the wrong way around? :)

It's asserting that sys_page_size == 0, so the error is displayed because sys_page_size is something other than zero.

Little update from me:
I'm now using
Firefox Ver. 22.0-1
glib 2.36.3-2

And Firefox does not crash immediately at startup and is normal usable.
Firefox still crashes sometimes though (like once within two hours).

Same thing with Fedora 19.

[Karlt (karlt)]

g_slice_set_config() is labelled "internal debugging API" (in 2.32.4 at least), and so Gecko should not be using this.
But, unless GLib has been compiled with G_DISABLE_CHECKS, this call will be a no-op, and so will not prevent the app from starting.

It seems unfortunate that different libraries and apps have a need to implement their own allocators.

This is interesting. Because while my firefox 24.1esr (slackware 14.1 package) does complaint about the g_slice_set_config, it's still able to run. But my friend's firefox was unable to runs (#38).

I am using ATI Radeon HD 6310 with radeon open source driver (linux 3.12.0) and mesa 9.2.3 (slackware's original package was 9.1.7), instead of amd catalyst/fglrx

replace g_slice_set_config with G_SLICE env var

Review of attachment 8367119:
-----------------------------------------------------------------

Considering g_slice_set_config is only deprecated at the moment, I'd rather use it and fallback to environment variables if it can't be used.
Also, you're only touching browser, while at least b2g and xulrunner have the same initialization code (which is why it was better in nsAppRunner in the first place, but i guess it's too late there).

[Karlt (karlt)]

On irc, glandium indicated that he would prefer to dlopen libglib (before anything depends on libgobject) and use the deprecated g_slice_set_config internal debugging api, than follow Matthias' suggestion to use GSLICE=always-malloc, because of the awkwardness of putenv/unsetenv.

Note you can actually just use g_slice_set_config directly, and build with -lglib-2.0. Makes it less easy to do that centrally, though.

This bug locks up Thunderbird in the Arch Linux Open Box Manjaro distribution (both 32 & 64 bit) after the update packages below are installed. The error popped up between the last iso image (11-26-2013) and now. The version 28.0 Firefox beta package runs fine. Since Arch Linux is a rolling distribution one (or more) of the listed update packages are causing the error. If I don't install the package updates both Thunderbird and Firefox work fine but they break after the package updates are applied. Someone smarter than me might be able guess which package is most likely to be causing the problem.

Same problem with Mozilla Firefox 27.0.1 on FreeBSD 10.0-STABLE / amd64 (and same for some previous versions of Firefox and FreeBSD).

When I launch it, I get the error:

A firefox process is running, but no window is displayed.

To be able to run it, I have to enter `firefox -safe-mode' and reset it.

Similar issue with Seamonkey 2.24 on Gentoo 64-bit. I also tried compiling with -O0 and the debug use flag. The GLib message appears (I use GLib 2.36.4). Some UI actions, especially scrollbar (seldom) and dropdown menus (almost everytime) lead to crashes with the message "Speicherzugriffsfehler" (don't know the non-localized message, but it means "Memory Access Error"). The crash is also not mentioned in about:telemetry, even if telemetry is enabled. Breakpad does not even realize the crash and I am unable to provide a dump.

In safe-mode there is a chance that the message "###!!! [Child][MessageChannel::SendAndWait] Error: Channel error: cannot send/recv" appears before. In normal mode the "no loadgroup notificationCallbacks" message from the Google phishing filter sometimes shows up.

YF, my understanding is this bug will not cause a crash like Bug 986735.

The "GLib-CRITICAL" warning is printed when Firefox starts.
It may cause a crash at startup on some systems. (although I don't think it really happens)
But it should not cause a crash when you open "2 tabs".

I jumped to premature conclusions, I have no evidence this is this bug what's causing my FF28 to crash. I just saw the same error message in FF as in Thunderbird and they seem to crash in a similar fashion and comment 3 was consistent with my experience.
See comment 27, Karl Tomlinson seems to know what he is talking about. My glib is not built with G_DISABLE_CHECKS and so according to Karl, should be a no-op, a 'do nothing'-instruction. I've never seen a crash on an empty startup.
Sorry for spreading confusion.
Firefox does have some major problem on Linux, just guess this bug is not the root cause.
Perhaps bug 920200 as suggested by comment 36, tho the last word over there is 'it shouldn't really happen'.

Firefox not crash, the error appaer only in the shell (even in the nighly).

[Vseerror (vseerror)]

So this is strictly a warning and does not prevent startup?
What about comment 1, 3, ...?

[Mte90net (mte90net)]

On Firefox Nightly, on Icewasel 32, Icedove 30 on debian sid i get only this error in console but the software works.

I think that a fix improve the perfomance in many distro, if the software crash on ubuntu or other I think would exist many reports of crash about this.

In the italian community we have a topic about ubuntu http://forum.mozillaitalia.org/index.php?topic=58583.0 and a thread about this ticket http://forum.mozillaitalia.org/index.php?topic=60934.0.

I don't see any crash stack traces linking the crashes to this assertion failure.

Everyone on modern systems will be getting this assertion failure, including those that crash on startup.

Thanks for the info. So this is a common issue. (and misleading for the uneducated)

[Murthy-rms (murthy-rms)]

Ok, if [(process:1032): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed] is a warning.

After a few minutes a *SEGMENTATION* fault. and the whole browser window goes for a toss.

This is a very very much essential application. I can say that I'm addicted to firefox as I'm using it from a very long time.

I have started the firefox in the terminal by disabling the GTK modules [GTK_IM_MODULE=xim /usr/bin/firefox]. But not happy with this work around too.

Request good people at mozilla to provide a fix ASAP. This a very critical issue.

That's interesting. Would you be able to file a new bug, cc me and report which module was causing the problem, please?

[Murthy-rms (murthy-rms)]

Disabled scim gtk immodule and started firefox with command [GTK_IM_MODULE=xim /usr/bin/firefox]
in the terminal. After some couple of hours FF crashed saying *Segmentation* fault.

Though the crash is not very immediate. I'm on Slackware64 14.1 [Kernel - 3.10.17, & with No multilib enabled]. But this needs a quick attention.

Even though i have Slackware64 14.0 in my another HDD [kernel - 3.2.29, & with Multilib enabled] their the any version of firefox works like a charm.

Every time I attempt to run the apport-bug bug reporting command, it tries to load data into an instance of firefox [30, 31, 32] which repeatedly fails with Firefox reporting:

Firefox cannot find the file at <current working dir path>/https://bugs.launchpad.net/ubuntu/+source/apport/+filebug/<long_id_string>

The first warning is a ubuntu bug. The second is apparently issued by Firefox and is likely responsible for the command failing.

GSLICE=always-malloc ENV is the only way how to disable it in glib >= 2.35. g_slice_set_config() actually does nothing because it tweaks only a local copy of slice_config which is not send to the allocator. The actual slice_config_init() config routine has its SliceConfig *config for that.

With the release of Firefox 35 today, Firefox 34 is EOL. If you think this warrants tracking, please request tracking for a current release. Note that as this is an old bug, unless there has been a recent change in severity, it is unlikely that this will be fixed before Firefox 38 (current Nightly).

How can we request tracking for current release? This is clearly still a bug in FF38 nightly.

Shut down and restart; start Thunderbird via command line and get same error message, however now a blank calendar page opens with the header: "January 18 - February 14, 2015 - Mozilla Thunderbird"

[Yuri (yuri-tsoft)]

I have the same problem, FreeBSD-10.1 amd64, fresh system install from scratch in VM, firefox-36.0.1, dwm window manager, G_SLICE workaround doesn't help, --safe-mode also doesn't help. FF prints the warning and freezes. No FF window opens.

It fails on xorg in VM, but same FF succeeds on Xnest in VM, and on my binary-identical host system.

I obtained xdpyinfo log in all three cases, see attachments:
firefox-hang-VM-in-xorg.txt : hangs on xorg in VM
firefox-fine-VM-in-xnest.txt : works fine on xnest in VM
firefox-fine-host.txt : works fine on xorg on host system

When I compare dpyinfo from xorg in host system (where ff works), and dpyinfo from xorg in VM system (where ff hangs), the main difference is that on host it has extra extensions NV-CONTROL, NV-GLX and XINERAMA. And on VM xorg it has SGI-GLX. I suspect this SGI-GLX causes ff to hang. Xnest server doesn't have any GLX, so it works too.

Someone from the development team should just reproduce it. I can tell you step by step how to do this with FreeBSD:
1. Download FreeBSD 10.1 amd64 disc1.iso
2. Install OS off that iso into VirtualBox VM with 3GB disk
3. Boot, and as root install all with the following command: pkg install firefox xorg xinit hal dbus dwm dmenu
4. Add these two lines into /etc/rc,conf: hald_enable="YES" / dbus_enable="YES"
5. As a regular user create file .xinitrc with "exec dwm" in it
6. Run startx, in dwm use Shift-Alt-Enter to open terminal
7. Run firefox and observe the problem

In all cases, working or not, it prints this warning:
(process:58625): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

Hope this helps.

Confirming the bug on my freshly installed system (complete with 'yum update'):

$ firefox -version
(process:6939): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
Mozilla Firefox 37.0.1

$ uname -r
3.19.3-200.fc21.x86_64

Using -safe-mode makes no difference.

Setting G_SLICE (or GSLICE, don't know which it is, seen both in this report) to 'always-malloc' makes no diff either.

For the record, Firefox seems to run okay, but when it comes to a CRITICAL error in my terminal, I'm a hater...

[Enkouyami (furyhamster)]

Thunderbird 31.6.0 is affected by this.

Which firefox version will finally fix this bug?

@jbrown: Who knows? The application has clearly escaped the intellectual control of the developers.

0001-Bug-833117-Replace-g_slice_set_config-with-G_SLICE-e.patch

Using g_slice_set_config() fails with newer glib because the slice allocator
now has a static constructor that runs when glib is loaded, consequently
emitting a noisy error message which confuses people into believing it's the
root of their problems.

The only way left to force the slice allocator to use "system" malloc (in
practice, jemalloc) is to set the G_SLICE environment variable to
always-malloc, and that needs to happen before glib is loaded.

Fortunately, the firefox and plugin-container executables don't depend on
glib. Unfortunately, webapprt does, so the problem remains for web apps
running through it. xpcshell and other executables that depend on libxul
directly (as opposed to loading it dynamically) are not covered either.

I tend to think function types are more readable with typedefs, but whatever.

I don't think we should assume it is safe to use mGSlice later.

man 3p getenv

be overwritten by a subsequent call to getenv(), setenv(), unsetenv(), or (if
supported) putenv()"

I had intentionally chosen not to override an existing G_SLICE environment
variable so that this could be overridden or debug-blocks could be used if
desired. That's not a show-stopper, but avoiding overriding would avoid
having to copy the old value to restore.

I don't know why you are preferring setenv over putenv here.
I had chosen putenv to avoid the leak.

There is discussion about possible getenv optimizations if putenv is not used,
but I don't see this in glibc.

Declare with "auto" type, if you like.

I guess that would work just as much. I was worried that some systems might have G_SLICE set for some wrong reasons. I don't have a strong opinion anyways.

I chose setenv to avoid having both "G_SLICE" and "G_SLICE=always-malloc" as .rodata.

What's the followup bug for that ? Shall we change our requirements for glib and fixe these ?

Replace g_slice_set_config() with G_SLICE environment variable

Turns out there aren't many places where g_thread_init is actually called. There's some webrtc code that we don't build, and other than that, other uses are exclusive... but need to be factored in, so this became a bit awful. At the same time I added a compile time glib check that removes the g_thread_init call when building against glib >= 2.32, which is the case for gtk3 builds.

Comment on attachment 8630422
Replace g_slice_set_config() with G_SLICE environment variable

The g_type_init() call has been dropped.
I don't know of a static constructor using GSlice in GLib 2.32.
Is there something that causes G_SLICE to be read during XPCOMGlueStartup with
GLib 2.32?
It would be good to keep this working for 2.32 because that is what the
precise test machines use.

>+#if defined(MOZ_WIDGET_GTK)
>+#if !GLIB_CHECK_VERSION(2, 32, 0)

The compile time glib version check is contrary to our goal of compiling the same code irrespective of the compile environment.

Can this just be "if MOZ_WIDGET_GTK == 2" ?

I'd also be happy to drop support for G_SLICE=always-malloc on versions prior
to 2.32 if that makes the g_thread_init situation simpler. However, I don't
know whether it is acceptable to call g_thread_init after g_type_init in
versions prior to 2.24.

Yeah, I was mistaken, I thought there was, but there isn't. Only g_thread is initialized, not g_slice.

I thought that too, and then I found a bunch of preprocessor glib version checks (various GLIB_CHECK_VERSION in harfbuzz, and various GLIB_MAJOR/MINOR_VERSION checks here and there, although, looking at them, they are actually useless because they're for versions even older than what we support ; harfbuzz does check for versions well above 2.18).

sure

g_thread_init can be called multiple times in versions >= 2.24, and gtype.c says, about g_type_init, "Since version 2.24 this also initializes the thread system". So if we're okay with dropping G_SLICE=always-malloc for versions 2.18 to 2.23 included, we should be able to get away with only calling g_type_init. Another option would be to just call g_slice_alloc/g_slice_free1, which will obviously initialize gslice, and after all, sounds much simpler.

Thoughts?

There are many options, and I don't think it matters too much.

It looks like the pre-2.24 code at least attempts to deal with g_slice used
before g_thread_init [1], even though taking advantage of this would not be
complying with the docs.

The most safe would be to either version check or always
g_thread_init before g_type/g_slice usage, though it seems this is probably
not necessary.

It probably comes down to what is simplest.

My instinct is to avoid allocations where possible, so I'd tend to g_type_init
instead of g_slice_alloc because a g_type_init will be required at some
stage anyway, but that is likely premature optimization here if there
something simpler. g_type_init is a single symbol and g_slice_alloc would require finding two.

The new method in nsXULAppAPI.h can mean that everything can be done from there
with only a single GetSymbol(), if you want to keep the g_thread_init. It could be renamed to XRE_GLibInit() to do more than just g_thread_init.
Still I'm OK with dropping XRE_g_thread_init altogether and not bothering with
g_thread_init from XPCOMGlueStartup if you prefer.

Can you note the need/reason for g_type_init somewhere please?

Perhaps "GLib version < 2.36 doesn't initialize g_slice in a static
initializer. Ensure this happens through g_thread_init (GLib version < 2.32)
or g_type_init (2.32 <= GLib version < 2.36)."
