(hat: desktop) Looks pretty good, needs more testing. Grab it. (In reply to sigsys from comment #0) I think you have to acquire the lock earlier, before the setfsent call. (In reply to Tijl Coosemans from comment #2) Oops you're right. Better to move the call down while at it? No need to protect the sysctls. --- gio/gunixmounts.c.orig 2020-10-01 09:17:53.138733000 -0400 +++ gio/gunixmounts.c 2020-10-15 13:05:40.628175000 -0400 @@ -1389,6 +1389,8 @@ #elif (defined(HAVE_GETVFSSTAT) || defined(HAVE_GETFSSTAT)) && defined(HAVE_FSTAB_H) && defined(HAVE_SYS_MOUNT_H) +G_LOCK_DEFINE_STATIC(getfsent); + static GList * _g_get_unix_mount_points (void) { @@ -1400,9 +1402,6 @@ struct stat sb; #endif - if (!setfsent ()) - return NULL; - return_list = NULL; #ifdef HAVE_SYS_SYSCTL_H @@ -1433,6 +1432,11 @@ #endif #endif + G_LOCK (getfsent); + if (!setfsent ()) { + G_UNLOCK (getfsent); + return NULL; + } while ((fstab = getfsent ()) != NULL) { gboolean is_read_only = FALSE; @@ -1468,6 +1472,7 @@ } endfsent (); + G_UNLOCK (getfsent); return g_list_reverse (return_list); } I have got a similar problem with x11-fm/caja:

The first patch fixed the problem.
(In reply to sigsys from comment #3) > Better to move the call down while at it? No need to protect the sysctls. Yes, looks good to me. It's unlikely that setfsent fails so calling it early to be able to return early on failure doesn't gain much in practice. Core file '/tmp/thunar.01.core' (x86_64) was loaded.

IMHO getfsent() is very legacy API, getmntinfo() can do same but threadsafe by design. https://www.freebsd.org/cgi/man.cgi?query=getmntinfo&apropos=0&sektion=3&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html (In reply to rozhuk.im from comment #7) Use of getfsent is correct here. Glib has two functions, one that returns "mount points" from /etc/fstab using getfsent and another that returns "mounts" using getfsstat (not getmntinfo). If I understand the BUGS section in the getmntinfo manpage correctly it isn't thread safe. Ugly glib`s gio strikes again... (In reply to Tijl Coosemans from comment #8) Yes, but getfsstat() looks like thread safe. https://www.freebsd.org/cgi/man.cgi?query=getfsstat&sektion=2&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports Calling g_unix_mount_points_get() instead of g_unix_mounts_get() - very strange design for g_file_enumerator_next_file(). g_unix_mounts_get() - uses getfsstat(). g_unix_mount_points_get() - with parsing /etc/fstab looks like some staff for dbus or other software that should deal with mount/unmount only. I dig inside this.

This code path check is "x-gvfs-notrash" present in mount options.
As for me, better to patch this:
GList *
g_unix_mount_points_get (guint64 *time_read)
{
if (time_read)
*time_read = get_mount_points_timestamp ();
return _g_get_unix_mount_points ();
}
add lock and cache.

I hope this will fix crash and improve speed.
Test required, I build and run thunar with it, but it does not always crash so I'm not sure that issue fixed.
fluffy, I think you should commit the patch from comment 3 while we wait for upstream to review the patch from comment 11. (In reply to Tijl Coosemans from comment #13) I think the same.

I had thunar crashing from time to time (especially in large directories) due to concurrent use of getfsent() (which is not thread-safe).
