libsysprof-profile: add SysprofMemoryUsage
...
Ports sysprof-memory-source.c to the new SysprofInstrument API.

libsysprof-profile: add ld_preload helper
...
This is to be used by instruments to adjust the spawnable to inject preload
into the spawned environment.

libsysprof-profiler: allow specifying test-profiler argv
...
You can `./test-profiler -- ls -lsah` to profile a subprocess and have
the profiler exit when the subprocess exits.

libsysprof-profile: spawn spawnable and escape upon exit
...
We can use the new infinite future here to mimic running forever when there
is no spawnable. Otherwise, if the spawnable exits we want to break out
of the recording loop.
2023-06-02 16:27:41 -07:00

libsysprof-profile: give Profiler a spawnable

And pass it along to the recording so that it can manage spawning the
subprocess during the record loop.

libsysprof-profile: add trace_fd helper for spawnable
...
I'd like to stop using tracefd, but since we need to maintain compatability
with older tooling, lets at least make it more ergonomic than adding an
instrument(s) for it.
2023-06-02 15:57:46 -07:00

libsysprof-profile: add SysprofDiskUsage

This is essentially the SysprofDiskstatSource in libsysprof ported to the
new instruments API.

libsysprof-profiler: add scaffolding for disk usage
...
This still needs porting from libsysprof, but this gets the scaffolding in
place to bring over those counters.
2023-06-02 13:38:03 -07:00

libsysprof-profile: add augmentation phase to instruments
...
This allows an instrument to augment the capture with additional
information before the capture is closed/flushed to storage.

libsysprof-profile: add wrappers for instrument vfuncs
...
For maintainability, I'd prefer to keep these calls going through a wrapper
function. They get inlined likely by the compiler anyway.

currently.

contrib: move line reader to contrib
...
This came from Builder, and it's nice to be able to use it statically from
multiple libsysprof libraries.
2023-05-30 21:29:24 -07:00
52684c7a12
libsysprof-profile: start on cpu usage instrument
...
The goal here is to do the whole thing on a fiber rather than how we were
doing it before. This just gets the counter registration going, but we
need to follow up with the parsing/lseek/etc code.
2023-05-30 18:41:56 -07:00

libsysprof-profile: capture podman overlays and containerenv
...
Additionally keep information about .flatpak-info so that we can
reconstruct which symbols are needed without build-id support.
2023-05-30 17:58:37 -07:00
9f9f953d53
libsysprof-profile: import podman utils
...
This comes from libsysprof, which we hope to remove as part of this move
to libsysprof-profile vs libsysprof-analyze.

libsysprof-profile: add API to notify of process started
...
This will be used when we discover a process started like when the Perf
instrument gets PERF_RECORD_COMM.
2023-05-30 17:27:33 -07:00
ee3a78433f
libsysprof-profile: add processes during recording
...
We want to reduce the chances we miss things between prepare and record
virtual methods, so delay the adding of processes until the recording is
started. We may get duplicate records, but we can deal with that when
analyzing the capture.
2023-05-30 17:12:19 -07:00
5c825c1fb5
libsysprof-profile: add some basic process information
...
This needs to get into the capture, and we still need to respond to the
discovery of new processes as well (which we lack API for).
2023-05-30 17:06:28 -07:00
81317bc1ca
libsysprof-profile: add recording helper to capture file data
...
We might have the file data from the peer and can specify the data in the
capture writer directly.
It may be useful to allow compressing these too, but we can deal with that
at a later time.
2023-05-30 17:00:53 -07:00

libsysprof-profile: remove frame overhead from max data length
...
Just so that we can potentially fit multiple of these per buffering in the
capture writer.
2023-05-30 17:00:00 -07:00
f91e13e055
libsysprof-profile: require org.gnome.sysprof3.profile policy

This will be needed to read the given proc files that should be captured
in the recording.

libsysprof-profile: use dex_bus_get()

This allows us to remove the synchronous call here from the fiber calling
into this API.
2023-05-30 16:05:01 -07:00
f9be133913
libsysprof-profile: implement loading files via sysprofd
...
If we need access to a privileged file in /proc or /sys we need to get
that through sysprofd. This implements basic checking of paths to see
if we need to get a /proc file from there.
We can't use the GetProfFD variant because that may still cause errors
when reading back due to how selinux and other LSMs may restrict read()
to get kallsyms.
This requires recent API additions in libdex.

libsysprof-analyze: decompress if necessary in dup_bytes()
...
If we are trying to get the file bytes and they are compressed, we may need
to transparently decompress those bytes. That way if the API requested
"/proc/cpuinfo" but really got "/proc/cpuinfo.gz" it still gets the same
bytes to consume.
2023-05-30 13:19:57 -07:00
1e8e1adb73
libsysprof-analyze: automatically handle compressed streams
...
If we want /proc/kallsyms and we discover /proc/kallsyms.gz, then use the
/proc/kallsyms.gz instead and transparently decompress it. Also, list the
file in sysprof_document_list_files() as /proc/kallsyms instead of
/proc/kallsyms.gz as that is really the intention (but mark the compressed
bit for decoding the chunks).

This instrument is meant to gather information about the host that we will

We use this in various places but it relies on some static API in the
libsysprof-capture. Make it available to the other libraries.
