This is meant to allow us to find the debug files for a given library for
podman containers running as the current user. However, we still need to
try to translate the fuse-overlayfs paths when parsing the /proc/pid/mounts
or we'll have incorrect paths coming from the event stream.
If the path provided to us is an executable program (instead of a syscap
file) then we can setup the path as the binary to execute in the profiler
assistant and save the user a couple clicks.
This ensures that we only have one thread doing reloads of stack frame
depths at a time. While we only ref the reader in the state, it should
still be fine because cursors *always* make a copy of the reader for their
internal use. I don't think this should fix#23, but it may reduce the
chances of it happening.
It's unclear to me what could cause #23 to happen, unless for some reason
multiple threads were sharing the reader's internal buffer causing the
frame-> dereferences to be junk. But as stated with reader copies, that
should not be able to happen.
Another possible avenue is that the task is cancelled and for some reason
the task is clearing the task data while the thread is running. Again,
that is not supposed to be possible given the design of GTask as it
should not release task data until finalized.
This changes a couple of our structures to use the atomic rc box instead
of gslice directly. It shouldn't affect anything, just some general
modernization while looking at #23
On a Raspberry PI 4, Sysprof crashes immediately when
trying to memchr() on the 'line' variable. The current
RPI4 support is poor on Linux mainline admitedly, but
having Sysprof to work on it at least gives us a chance
to profile the major bottlenecks.
Protect against NULL 'line'.
The annotation applies to the method as a whole, not to individual
arguments, so the existing annotations don't have any effect.
This was hidden by gdbus-codegen's automatic handling of arguments
of type 'h', but that change was reverted, resulting in a broken
build.
GLib is already doing this, which broke a number of auto-generated code.
This tracks those changes and manually sets the annotations so that we
are guaranteed to get this behavior.
We'll need to fix other uses (such as in Mutter), but we have to do that
already because of the change in GLib.
Fixes#17
