Release 1.0g Feb 11, 2011

This is release 1.0g of Telemetry with the following changes since 1.0f

Run-time

Enhancement: tmSignalLockCount support for semaphores!
Enhancement: tmBeginTimespan and tmEndTimeSpan support!
Change: tmOpen now accepts names with spaces in them and automatically substitutes underscores
Change: tmLoadTelemetry now tries to load first from the EXE path, and then without a path (which means the standard Windows search order is used)
Bugfix: fixed race condition in 360 context switch capture that was causing rare memory corruption
Bugfix: callstacks that were very deep (more than 32 levels) were truncated

Visualizer

Enhancement: you can now specify the location of acquired data! Click on the "..." button after stopping the integrated server, then select the directory where you'd like acquired data to go.
Enhancement: generated plot interface is cleaner
Enhancement: generated plots now support by-frame window sizes
Enhancement: generated plots now support centered instead of just trailing window
Enhancement: semaphore support! Visualize multiple threads taking a semaphore and when semaphores are increment!
Enhancement: you can now specify the storage directory for the server in the Visualizer!
Enhancement: timespan support! Look at arbitrary timespans that straddle threads in a separate track!
Change: revamped internal options/cvar system
Change: gold color for threads now reserved for system threads
Change: fixed how names are displayed in context view track on 360

Bugfix: fixed tmsym bug where its internal buffers would overflow with large data dumps from the server

Release 1.0f January 17, 2011

This is release 1.0f of Telemetry with the following changes since 1.0e

Run-time

Change: tmOpen now blocks while waiting for handshake
Change: tmTick now only sends packets after handshake received
Enhancement: network traffic plot is automatically generated now
Bugfix: run-time could get hung when server went away unexpectedly
Bugfix: fixed a race condition for context switch queue thread startup on 360
Bugfix: fixed off-by-1 memory overwrite bug in 360 context switch queue handling

Visualizer

Enhancement: lock track revised! Now you can see which threads are blocking on a lock instead of just which one has ownership.
Enhancement: zone tooltip now displays the lock it's waiting on if it's a stall zone generated due to a tmTryLock
Enhancement: context switch lines are drawn as thin lines if they're waiting on a resource instead of switched to another thread of execution. For example on 360 if you're waiting for a mutex but don't have another thread to run the scheduler will make you idle, but instead of seeing this as swapped to the system, you'll see it as your own thread still running but waiting.
Enhancement: known system threads on 360 are rendered in yellow on the context switch queue track
Enhancement: BETA implementation of generated plots! Now you can right click a plot in the plot window and generate a new plot consisting of the average or sum of values over a window or the entire run duration. This will be enhanced significantly in the coming weeks.
Change: slightly widened zoom extents when zooming into a zone
Bugfix: clicking on frame header or double clicking in minitimeline in zone view weren't working
Bugfix: fixed double hit processing of mouse click in zone view
Bugfix: small memory leak with thread name and lock name events fixed
Bugfix: gui state wasn't being reset with 'last captured' and 'last viewed' which would lead to some weird visual glitches
Bugfix: race condition when exiting Visualizer while still connected fixed
Bugfix: when hovering over a plot label and then moving off, the old plot would stay 'hot', not the hot plot is reset to none
Change: when 'Locks' track is minimized it's now called 'Locks' instead of 'Mutexes'
Change: increased alpha for faded out plots

Server

Enhancement: optimized background network traffic sending to reduce potential hitches in performance from large data buffer sends
Bugfix: lock pointers and accumulation zone counts were not properly stored to disk
Bugfix: server more robustly catches client side failures/disconnects such as excessive zones
Bugfix: server no longer keeps a connection alive when the associated cooking thread is no longer live

Other

Change: examples cleaned up a bit
Bugfix: fixed documentation error on how to wait for context switch queues to finish

Release 1.0e January 10, 2011

This is release 1.0e of Telemetry with the following changes since 1.0d.

Run-time

Enhancement: we now support context switch Visualization on the 360!! Watch each hardware thread as software threads switch in and out.
Enhancement: TMPT_PERCENTAGE_DIRECT value of TmPlotType now works with integer plot calls
Enhancement: We're now shipping with a 'checked' build of Telemetry. Specify 1 to tmLoadTelemetry and the checked build loads with lots of debug information sent to your debug window! Note that the checked libraries are now appended with the letter 'c' instead of the letter 'd' (e.g. telemetry64c.dll).
Enhancement: run-time detects out of date server/wrong protocol version and returns TMERR_BAD_HANDSHAKE
Bugfix: Variable argument lists to the various plot commands would result in a run-time crash.
Bugfix: tmGetPlatformInformation was not exported on the 360 library.
Enhancement: No more stalls when calling tmTick while flipping buffer pointers! Telemetry's data buffers are now flipped and sent to the network only after a timeout (one second) or when they are more than half-full. This means low traffic but high frame rate (>250fps) isn't artificially throttled waiting on the network.
Enhancement: We now use DisconnectEx on Windows in an attempt to flush the buffers before closing sockets.
Change: We no longer generate a network traffic plot since it's no longer guaranteed to happen at tick time. This will be reimplemented
Change: some of the TMERR_* codes have been renumbered later.

Visualizer

Enhancement: we now support context switch Visualization on the 360!! Watch each core as threads switch in and out.
Enhancement: hovering over the name of a plot in the plot tree highlights that plot
Enhancement: current panel is now saved as part of the undo state (i.e. ctrl-z is basically a 'back' button)
Enhancement: mouse thumb/back button is synonymous with using ctrl-z to undo view state
Enhancement: Visualizer now throws up a warning if you try to load a dataset with no frames
Bugfix: bad server commands will result in disconnection instead of continuing in bad state
Bugfix: bug with right-click bringing up too many menus on some zones
Bugfix: race condition fixed when incoming frame summaries were purged before being referenced
Bugfix: fixed rare memory leak in lock event handling
Bugfix: text renders properly when using Remote Desktop and the Visualizer
Bugfix: protocol negotiation was buggy, so mismatched server/Visualizer could result in weird behaviour

Server

Bugfix: protocol negotiation was buggy, so mismatched server/Visualizer could result in weird behaviour
Enhancement: You can now specify if you want to limit connections to the Visualizer or the profiler with the -deny [Visualizer|profiler] command line options.
Bugfix: date/time wasn't properly handled for session times with 360
Bugfix: Server did not handle executable filenames with spaces in them properly, resulting in missing sessions.
Bugfix: Server wasn't accurately differentiating between "number of zones received" and "number of zones stored to disk". The latter is clamped to 64K zone children per zone so sometimes the reported zone count for very high numbers would not match the actual number of zones. We now store actual number of zones instead of the number of zones received.
Bugfix: Some server side warnings were inadvertently triggering fatal error handling.
Enhancement: The server kicks inactive/idle profiler clients. The default timeout is 10 minutes, but can be overridden with the -timeout command line.
Enhancement: The server kicks multiple connections from the same source (machine name + IP + app name) unless specifically asked not to by the client with TMOF_DONT_KILL_OTHER_SESSIONS

Bugfix/Change: 360: we now parse IP addresses first using inet_addr instead of relying on DNS lookup, this should fix connection problems some customers were having
Change: TMPT_PERCENTAGE_DIRECT value of TmPlotType values are ignored and error set unless calling tmPlot or tmPlotF64
Enhancement: there are now typed versions of tmPlot, specifically tmPlotF64, tmPlotU32, tmPlotI32, tmPlotU64, and tmPlotI64

Visualizer

Change: Search for license keys in EXE directory if none found in the Telemetry data directory
Bugfix: TMPT_PERCENTAGE_COMPUTED value of TmPlotType was not properly supported
