[tracecompass-dev] New and Noteworthy February 2016

Hi,

See below for the New & Noteworthy and ongoing work of the Trace Compass project for January 2016.

New and Noteworthy:

Expose clock_offset in Properties view for LTTng CTF traces. This can be used to manually time offset a trace within an experiment where multiple LTTng CTF traces taken on the same machine and time have different UTC offset values (Trace Compass 1.2/Mars.2, see [1])
Support of sorting in Control Flow view based on column selection. The hierarchy, i.e. the parent-child relationship, is kept. (Trace Compass 2.0/Neon, see [2])
Persist thread selection and sort order in Time Graph views (e.g. Control Flow view) for all open traces (see [2])
Show thread priority in Critical Path view. With this it's possible to detect if a higher priority process was block by a lower priority process (see [2])
Added dialog to manage XML analyses in order to import/export/delete XML analysis files (see [2])
Fix Linux Kernel analysis for 32 bit applications running on 64 bit Kernel (see [2])
Allow recording of LTTng trace snapshots when session is inactive (see [2])
Display analysis properties (e.g. file sizes of state system) in Properties view (see [2])
Added RCPTT module for UI testing. It includes a simple test for opening a trace and integration to nightly build.

Ongoing work:

Trace Compass release 1.2 as part of Mars.2 (Friday February 26, 2016)
Continue integrating data-driven pattern detection (enhanced filtering)
Add periodic marker source base implementation
Add marker axis in Time Graph Views with the possibility to hide and close marker categories
Improvement in visualization of Linux Kernel IRQ and SOFTIRQs in Time Graph views
Add support for creation of an experiment during import operation
Integration with LTTng Babeltrace Python analyses to be able to output the results of these external analyses into Trace Compass
