Guillaume Desmottes 3bb5c1e73a leaks tracer: add checkpoint support using SIGUSR2 
https://bugzilla.gnome.org/show_bug.cgi?id=767857
 2016-07-08 11:23:43 +03:00
Guillaume Desmottes 53d2e8c977 leaks tracer: log alive objects when receiving SIGUSR1 
We don't want to automatically catch signals so use an env variable to
enable this feature.

Tim-Philipp Müller 6446a1a45c tracers: leaks: some micro-optimisations 
- we know number of filter items is not going to change,
  but compiler doesn't

- only do GST_IS_TRACER check for GObjects, not mini objects

- use non-type check cast macros in performance critical paths

Guillaume Desmottes e0757e1d80 rusage: properly free the queue memory 
The queue is allocated as part of the tracer struct so we should not
use g_queue_free() to free it.

Stefan Sauer ec75b68984 tracerrecord: don't leak the spec structures 
Change the gst_tracer_record_new() api to take the parameters the make the
spec structure directly. This allows us to own the top-level structure and
also collect the args so that we can take ownership of the sub-structures.

Stefan Sauer f69382c5f9 tracer/gststats: fix mismatch between '.class' and tracer args 
Clean up from the recent changes. The logging descriptiors did not match what we logged.
 2016-01-20 09:14:12 +01:00
Tim-Philipp Müller 8641d7c911 tracers: fix thread-id casts to 64-bit ints on 32-bit systems 
https://bugzilla.gnome.org/show_bug.cgi?id=760762
 2016-01-18 11:28:28 +00:00
Stefan Sauer 84554af301 tracer/stats: use the right log template 
When porting we used the wrong record (copy and paste).
 2016-01-16 21:23:10 +01:00
Stefan Sauer af91d23204 tracer: use the new flags to create the optional field in the format string 
This spares us explicitly listing the field in the spec. and thus hide this
implementation detail.
 2016-01-16 19:21:00 +01:00
Stefan Sauer 8cd76a918a tracer: add a GstTracerValueFlags and replace strings 
This allows us to document the flags and makes the logs a bit smaller.
 2016-01-16 18:52:32 +01:00
Tim-Philipp Müller 8b88fc487f gst.h: Don't spew warnings if GST_USE_UNSTABLE_API is not defined 
Only hide GstTracer and GstTracerRecord API behind GST_USE_UNSTABLE_API,
but don't spew any warnings, otherwise everyone has to define this
to avoid compiler warnings.

This reverts parts of commit 89ee5d948d.
 2016-01-16 16:00:16 +00:00
Stefan Sauer 89ee5d948d tracer: add a GFlag for the tracer scope 
Port all tracers. Add the GST_USE_UNSTABLE_API flag to the internal CFLAGS so
that we don't have to specify this for gir, docs, mkenum, ...
 2016-01-16 13:31:51 +01:00
Stefan Sauer 10b78d872b tracerrecord: add a log record class 
We use this class to register tracer log entry metadata and build a log
template. With the log template we can serialize log data very efficiently.
This also simplifies the logging code, since that is now a simple varargs
function that is not exposing the implementation details.

Add docs for the new class and basic tests.

Remove the previous log handler.

Fixes #760267

Stefan Sauer 30741e0206 tracers: code clean ups 
Drop some trailing whilespace. Make field order consistent.
 2016-01-10 14:30:05 +01:00
Stefan Sauer 2f41e7bc6a tracer: harmonize the query hooks 
In post hooks always pass the return value as the last param. Pass the query
also to post hooks since it is still alive.

Stefan Sauer fb249dadcb tracers/stats: add missing parameters to callback functions 2016-01-07 22:47:37 +01:00
Stefan Sauer 5e40639be7 tracer: make gst_tracing_register_hook_id static 
We don't need to expose this as public API. Change the only plugin that was
using it.
 2016-01-06 20:46:58 +01:00
Thiago Santos 9f26e5cc63 tracers: log: add missing hooks 
Log all possible hooks

Thiago Santos cf5e7c03c2 stats: log the element-new hook properly 
To be able to get the time the elements were created instead of
just logging them without a time

Sebastian Dröge 2b8413e1cd tracers: Only link against libgstprintf.la if the debugging system is enabled 
It does not exist otherwise and linking will fail.

Stefan Sauer 34cf8f3252 makefile.am: Remove obsolete Android build cruft 
This is not needed any longer.
 2015-10-06 18:45:41 +02:00
Thiago Santos 7c5f7173c8 tracers: stats: add message structure to output 
The name of the message is not enough. For example, state-change
is not enough to know the transition.

Stefan Sauer 660049bb38 tracing: rename the global api to gst_tracing 
This makes it more obvious what is the api for tracer elements and what is api
for the global state.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 5e2770566f tracers: eliminate var_args 
Register tracer hooks as GCallback. Use macros for hook dispatch and cast the
hook functions back to the appropriate type.
 2015-10-05 20:59:39 +02:00
Stefan Sauer b10b10cf1e tracers: code cleanups 
Move static variables to instance variables. Add finalize methods. Remove code
that is commented out. Cleanup locking code.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 4881d1c16c tracer: use GQuark or strings for the hook id 
This way one can define new tracing probes without changing the core. We are
using our own quark table, as 1) we only want to initialize them if we're
tracing, 2) we want to share them with the tracers.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 1a3e218b89 tracer: simplify hook api 
Instead of a single invoke() function and a 'mask', register to individual
hooks. This avoids one level of indirection and allows us to remove the
hook enums. The message enms are now renamed to hook enums.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 7b24d76260 tracer: drop the HookId hid from the invoke method 
The MessageId is more detailed and anyway needed to interpret the varargs.

Stefan Sauer 3baaa4ba6f rusage: improve cpu load meassurements 
Get the number of cpus and scale process cpu-load accordingly. Switch the
cpuload to be per-mille to get smoother graphs. Add a bit more logging and use
the _OBJECT variant.
 2015-10-05 20:59:39 +02:00
Stefan Sauer dbb1897e9b rusage: implement windowing of cpuload 
Add a local help to the rusage plugin that supports windowing of values. We want
to generalize this for use in other plugins.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 018858980b rusage: announce the data format 
Rusage will now announce what is meassures and how it is logged. Use the new format in stats.
Cleanup the the code and naming.
 2015-10-05 20:59:39 +02:00
Stefan Sauer c13ee1f2e9 stats: improve cpu load meassurements 
Rename variables for clarity. Handle the initial disparity between debug time
and the time already spent in the proc and main thread.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 46ea9729df tracer: split into tracer and tracerutils 
Keep tracer base class in tracer and move core support into the utils module.
Add a unstable-api guard to the tracer.h so that external modules would need to
acknowledge the status by setting GST_USE_UNSTABLE_API.

Stefan Sauer 757d3400cd latency: take stop time when buffer is handled 
Now we meassure time from 'before buffer transfer on src' to when the 'buffer is processed on sink'.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 7dfc0a8ead tracers: add a logging helper to remove identical copies from the tracers 2015-10-05 20:59:39 +02:00
Stefan Sauer 635a4b5c00 tracers: tweak the get_real_pad_parent() 
By using the we ended up on the actual element, not the parent.
 2015-10-05 20:59:39 +02:00
Stefan Sauer 111b18115a tracers: add a new latency tracer 
Add a new tracer with pushes extra events to meassure src-to-sink processing latency.
 2015-10-05 20:59:39 +02:00
