If we get a container file that is in a format we don't quite understand,
avoid crashing and just bail. That will likely result in the inability
to symbolize properly, but better than crashing.
Fixes#100
We "know" that the swapper runs between each process inherently so no need
to really include that in the scheduler details. It just clutters up the
event timeline. Without it, we're more likely to see patterns in the
scribbles.
That is fine to do when the futures are finished, but in this case one
might still be in-flight. Also, wait for all futures to complete before
processing them. Use a finally() block so we can check even if there are
errors.
Doing this in reverse *and* making it incremental seems to work better than
just making them incremental. So do that so the UI stays responsive even
if it flickers to an empty set momentarily.
For now this only supports searching in the sender, destination, path,
interface and method fields. And will match if any of these fields
contain the search term as substring. In the future it may be nice to
allow searching individual fields as well as filter based on enum
fields.
This doesn't add support for the legacy symbol mangling scheme which is
currently the default pending support in tools for the v0 symbol
mangling scheme. The legacy symbol mangling scheme is similar enough to
C++'s symbol mangling scheme that demangling them using the C++
demangler generally produces readable symbols. The v0 scheme is entirely
custom and due to backreferences and encoding all generic arguments not
very readable when mangled, so supporting it is more important than
supporting the legacy scheme.
This is not installed currently. It's for testing now but we can start
installing it if/when people want to use it. We could also try to make
it part of sysprof-cli someday.
This tool prints the difference of two trees giving you a -/+ change of
the number of hits incurred on that frame-pointer.
While fixing things for Flatpak (which have a path deduplicating some
of the path parts) works there, it breaks locating the debuglink in
other places such as GNOME OS.
This tries both forms, using the long form first and then the short
form second, since Flatpak is likely a subset of everything that needs
to be located.
If we have a path like /app/bin/gnome-builder and the debug prefix is
/app/lib/debug then we don't want to end up with /app/lib/debug/app/bin
as the real data directory is /app/lib/debug/bin.
This often works with /usr because /usr/lib/debug/usr can link back to it's
parent. But we should try to do the right thing instead of relying on that
anyway.
We want the traceables to match the selection in either the callgraph or
the flamegraph, depending which is visible. The summary is not currently
implemented for flamegraph as it is already naturally a summary by virtue
of it's colorization.

This will get updated when a node is clicked/updated. The goal here is to
bind it from the SysprofSamplesSection so that the sidebar will update.

If the document is doing asynchronous work after it has been loaded (which
we use a progressbar to denote), then show a spinner for the activity.
