* This lets us detect when a remote server has been disconnected and
needs to be restarted, as well as alerting the user if this happens in
the middle of a replay session.
* Pinging other hosts means the context switcher is reasonably up to
date if one of them comes up.
* If the machine idents differ in significant ways that we'd consider
it to be a different platform (currently just OS), and if so mark it
as supported but suggested to be replayed remotely.
* In a couple of places I had to resort to if(IsHighContrast) but mostly
this is just using system brushes consistently or not assuming black
text.
* The default DockPanel theme doesn't work well, so make a minimal high-
contrast theme for it and assign it everywhere.
* The pipeline flow was using fixed colours, use system brushes for the
different elements and switch based on high-contrast to ensure active
and inactive stages are visible (using ActiveCaption looks bad on
normal themes because it's a big block of colour).
* For some reason the flat toolstrip renderer doesn't handle white-on-
black themes, but the system one does. It's a little clunkier but it
shows up correctly without writing tons of custom painting code.
* Range histogram uses a properly contrasting colour for the border.
* Treelist views use a better system colour for selected rows when
inactive and hovered rows (when high contrast).
* Mesh view grids have a system background instead of white
* Various things (pipeline state, mesh viewe) set text colour when
colourising backgrounds of things instead of assuming black.
* Previous versions accessing the http URLs will be redirected soon (as
of time of writing this). The POST /bugsubmit won't be redirected as
it's not feasible to redirect POST requests, but that will continue
working.
Notes
======
- Create a (hopefully) cross-backend performance statistics abstraction as part of FetchFrameInfo. This currently collects statistics about constant buffer binds, sampler binds, resource binds, client and server style resource updates (e.g. Map and UpdateSubresource), index & vertex buffer binds, and draws and dispatches. In my captures this covers approximately half of all API traffic. The rest is often shader sets, and then usual RS, OM, etc., that aren't currently tracked. During READING state parsing on the wrapped device context, record statistics about the calls and store them into the current frame info. We inspect objects occasionally to get things like their type for recording. It may be useful to expand this in the future to check bind types, etc. On the GL/Vulkan backends the stats data is never initialized and we display the same statistics data as before.
- Add a new statistics pane in the UI. A variety of shim arbitration/marshalling is provided to get the statistics data across the managed/native boundary. Removed the old statistics menu item. Currently the statistics pane is just a text log of various gathered data, with ASCII art (woo!) histograms. However in the future we would like to have image based historgrams as well as support for gathering statistics on a mask of stages, etc.
- Remove 'diagnostic' events (e.g. push/pop/marker) from the API call count as it distorts the API:draw call ratio.
- Add _First and _Count to ShaderResourceType and ShaderStageType for weak enumeration (weak due to int cast requirement).
- Provide utility functions Log2Floor for 32 and 64 bit types. These require OS specific clz, which are provided for Windows/VS and Linux/gcc/clang.
TODO
======
- UI toolkit based historgram, ability to set stages enabled for statistics, etc.
- Revisit necessity of gathering statistics across frames--apparently there is no multi-frame capture in a single log anymore?
- Revisit min/max/etc. gathering on the data--is there some way to improve this to not be so mechanical? Perhaps with field enumeration? However if moving to C++/Qt in future, possibly not a good time investment.
* Previously if a temporary log was saved once, it would be moved there,
so the user could in theory delete it and lose the only copy of the
log.
* Now the temporary log is held until it's closed in the UI, to be able
to be saved again. If the user saves the log though, this will stop
any "unsaved log" prompts in the main UI window, so there is nothing
stopping the user from saving the log, deleting that copy, then
closing and they'll lose the log without prompt.
* If hardware support for feature level 11 isn't present, fall back to
the WARP software rasterizer. This will support everything needed, but
it certainly won't run well.
* There are loud warnings - I added a debug message to the debug errors&
warnings window so the status bar will indicate that, and it's in the
title.
* At most once every 3 weeks there will also be a message box pop up
when loading a log, to remind the user so that it isn't forgotten, as
for obvious reasons this is not the intended use-case (hopefully once
per 3 weeks isn't too often to be annoying).
* This will allow the adding of things like 'redundant api call' for calls
that have no effect, as well as potential problems like drawing with an
empty viewport, or similar things that are common problems. Reading out-
of-bounds on buffers etc is a good example of 'defined' behaviour that
is probably not desired.
* These heuristics could also identify potential performance problems.
* It also supports adding debug messages after log-load time, so you could
do an additional extra-strength pass, or do a detailed check of one
draw call (e.g. a broken draw, to try and figure out the problem). If
there are any unread debug messages, the status bar will flash and the
debug messages window will show a count as (N).
* This way if someone updates their install without clicking the menu item
to clear this flag, it will still detect the update after a few days.
* (And when I forget to update which beta is latest, it will fix itself
eventually. Oops).
