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.

libsysprof-profile: add various CPU parsing

This still needs some work because the read operations are blocked
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.

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.

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

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

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

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

libsysprof-profile: use dex_bus_get()

into this API.

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).

libsysprof-profile: start on linux host info instrument
...
This instrument is meant to gather information about the host that we will
need as part of the capture to decode things properly.

build: add mapped_ring_buffer_sources for inclusion
...
We use this in various places but it relies on some static API in the
libsysprof-capture. Make it available to the other libraries.
2023-05-26 16:46:44 -07:00
55353aa185
libsysprof-profile: add record vfunc scaffolding

We still need to create the ring buffer and the source to stream it into
the capture writer, but that will come soon.

libsysprof-profile: implement prepare vfunc
...
This doesn't start reading from the input stream, but does get things into
place until we actually start processing the recording. When we get a
record vfunc, we will do the input processing.
2023-05-26 15:41:58 -07:00
800c32e303
libsysprof-profile: add private API to get recording spawnable

This will still need to be set by the profiler eventually, but this gets
the readback API in place so we can use it from instruments.
2023-05-26 15:37:39 -07:00
9494b403f4
libsysprof-profile: add SysprofSpawnable
...
This comes from libsysprof, but the goal here is to remove that library
after getting this one into shape. So C&P is fine for now.

libsysprof-profile: implement polkit checking with libdex
...
Also, I no longer wish to try to maintain support for no-polkit. If there
is truly a system where that is something we want to support, we can bring
back the shims as a compile time alternative.

build: add libdex-1 requirement for libsysprof-profile
...
Being able to manage asynchronous operations with libdex will drastically
simplify how we implement the profiler and instruments. We may eventually
do the same with libsysprof-analyze to parallelize some operations.
