RAD Telemetry 2.0N Released!

This release focuses on making the Visualizer more responsive.

Run-time

• Bugfix: fixed a bug where printf format strings containing 64-bit integers followed by strings would not work in certain cases.

Visualizer

• Bugfix: fixed UI flickering on cursor-key scrolling when hitting edges of the dataset.
• Bugfix: fixed a bug where semaphore lock counts would not get displayed in the visualizer.

• Enhancement: revised the protocol between Server and Visualizer. When using a dedicated server, network traffic to the visualizer is typically reduced by 5-6x!
• Enhancement: significantly reduced data fetch times from server.
• Enhancement: improved prefetching logic in the Visualizer. Waiting for data to load should happen much less often now.
• Enhancement: UI is now much more responsive when lots of zones are visible.

Server

Other

• Enhancement: (Linux) Telemetry now officially supports CentOS 6 and RHEL 6.

RAD Telemetry 2.0M Released!

Telemetry 2.0M has just been released.  This release focuses on reducing server-side processing time.

Run-time

• Change: On PS4, allocate context switch trace buffer directly from the kernel instead of using new[] so no large libc heap is required.

Visualizer

• Bugfix: fixed missing/flickering zones in presence of thread name changes.
• Bugfix: fixed incorrect messages appearing in "Log" view in certain cases.
• Enhancement: reduced fetch times for zones and plots.
• Enhancement: importing recorded runs from a file is now much faster and displays progress information.

Server

• Change: updated to SQLite 1.8.5.
• Enhancement: significant reduction in dataset processing time; in our tests, processing is now typically between 2 and 4 times faster.
• Enhancement: real-time indexing mode is now much faster - typically 30%-50% longer processing time than late indexing, instead of the 3x and more it was previously.
• Enhancement: processed datasets are now approximately 25% smaller due to a revised index structure.

RAD Telemetry 2.0L3 Released!

Telemetry 2.0L3 has just been released.  This is strictly a minor maintenance release to deal with some small bugs.

Visualizer

• Bugfix: fixed plot LOD rendering issues
• Bugfix: file import now works on file names with spaces
• Bugfix: path names with leading spaces now work
• Change: warn if we fail to launch tmimport32 or tm2sym
• Change: remove unused search and memory tabs
• Enhancement: added TDB double click support on windows

Other

• Enhancement: added docs on TMO_NULL_NETWORK

RAD Telemetry 2.0L released!

Telemetry 2.0L has just been released.  This is strictly a minor maintenance release to deal with some small bugs.

NOTE: The ABI has changed, so be sure to recompile/relink everything instead of just swapping out libraries!

Run Time

• Bugfix: varargs with float types were not handled properly at times on OS X (64-bit), Linux/x64 and PS4
• Bugfix: TM_VA_LIST parameters were incorrectly warned as 'stack variables' by checked build
• Change: Android runtime is now built with -funwind-tables by default
• Enhancement: checked build now does extra verification to watch for 'wrapper' related bugs

Server

• Bugfix: unknown string pointers are silently handled instead of generating an exception and associated disconnection
• Bugfix: locks/timespans could accidentally start with a negative ref count

Visualizer

• Enhancement: 'edit source code' is now a right-click zone option
• Bugfix: backgrounds were drawn in green instead of black of any timeline sections were present but the current visible area did not have one defined
• Bugfix: tooltip was not showing file name and line properly in zone view
• Bugfix: in some situations Visualizer on Windows would leave clipboard open, locking out other applications from copy/paste

Other

• Change: added documentation discussing the perils of wrapping calls to Telemetry vs. just using Telemetry in place

RAD Telemetry 2.0K is out!

Telemetry 2.0K is out the door!  The biggest new feature is context switch trapping support on PS4, putting it on a par with Windows and 360.  Also, the directory/file naming structure is no longer so rigid (so you can rename directories and TDB files).  Finally, fetch times for very dense sets of plots, zones, and messages are way faster now.  Some fetches that used to take 15 seconds now take < two seconds!

Note that the server/Visualizer/run-time need to be simultaneously upgraded since there is a small change in the protocol.

Run Time

• Enhancement: context switch capture on PS4
• Enhancement: add server configuration API (tmSetServerConfiguration)
• Bugfix: fixed bug where timespans could hang the run-time if tmOpen was called late
• Change: linux (and other BSD-ish) network implementation now spew debug on wouldblock (checked build)
• Change: disabled network policy on PS4 telemetry socket
• Enhancement: added TM_VAR macro and no longer exclude tmtypes.h on NTELEMETRY.  This means you can wrap Telemetry declarations and variables in a way that is compatible with NTELEMETRY, e.g TM_VAR(TmU64 x);

Server

• Change: unknown strings are a bit more known (null vs. unrecognized)
• Enhancement: decoupled sessions from their filenames, so you can now rename files/directories (yay!)
• Bugfix: fixed crash bug with oversized messages
• Bugfix: generated mem usage plots (via TMZF_MEM_REGION_EXPERIMENTAL) were using incorrect paths

Visualizer

• Enhancement: mousewheel now works in message view
• Enhancement: greatly sped up fetch times for zones, messages, plots, and mem events
• Enhancement: session notes are now on a separate line and green, and if then completely skipped
• Change: disable 'copy' button in message pane until all have arrived
• Change: messages without newlines now have newlines appended automatically
• Bugfix: fixed file/line missing from zone tooltips

RAD Telemetry 2.0j released!

This is a minor maintenance and bugfix release, but it does require a recompile/relink.

Run Time

• Enhancement: tmMessage now has a tmMessageEx variant. This was added so you can change zone label/sublabels in virtual threads.
• Enhancement: (Windows) you can now specify full path for TMDATA files when using TMCT_FILE captures
• Bugfix: fixed benign AppVerifier warning about dangling CriticalSection

Server

• Bugfix: in certain situations long zones would not be recorded properly
• Bugfix: fixed pathological edge case in zone garbage collector leading to N^2 processing times

Visualizer

• Change: (Windows) Visualizer now uses system default text editor instead of Notepad when editing notes
• Enhancement: plot scale with mousewheel should work now
• Bugfix: double clicking a frame in plot view would sometimes take you to the wrong location
• Bugfix: right-click 'zoom' on plot would sometimes take you to the wrong location

Other

• Enhancement: Mac/Linux/Win now have gpu_opengl.cpp sample file included in distributions
• Enhancement: Python SQLite export script has been greatly enhanced
• Change: 'tools' only distributions now included exporter script
• Change: updated zone filtering documentation
• Change: updated timespan document to note the ordering constraints of *TimespanAt APIs
