(profiler_core) Fixed bug with memory corruption in chunk_allocator;
(profiler_core) Event tracing now gathering info about process which owns thread;
(profiler_core) Thread names are stored before other blocks now;
(profiler_core) Removed unused block types: context switch and thread sign;
(profiler_core) Added some description for API;
(profiler_gui) Context switch events now painted in different colors: red = switch to another process, coral = switch to registered thread in the same process, black = switch to kernel mode (thread id == 0).
(profiler_gui) Added popup windows with information about context-switch or block under mouse cursor;
(profiler_core) Optimized storeBlock() algorithm, removed unnecessary std::vector;
(profiler_core) Writing to std::stringstream and then to file (prepare for streaming over WAN/LAN);
(profiler_core) Moved hached_cstr into separate header.
(profiler_core) Changed order of read/write of context switches as a preparation work to statistics gathering taking into account context switches duration.
(EasyGraphicsView) Selected item's text is now painted bold + removed selected item color, but made selected item's border more wide.
(profiler_gui) Colors adjustment.
It's need to run systemtap util for loading kernel module. This kernel module capture context switch timestamp and systemtap store it in the temp file.
Before running profiling application you should run systemtap script with root privileges as following:
\# stap -o /tmp/cs_profiling_info.log scripts/context_switch_logger.stp name APPLICATION_NAME
where APPLICATION_NAME is profiling application
(profiler_gui) Moving sources into separate files;
(profiler_gui) Rename Prof* classes into Easy*;
(EasyGraphicsView) Optimized performance by not painting items which were not expanded in TreeWidget. While there are no range selected for TreeWidget, only top-level blocks are painted on scene.
