- ShpReader will copy the input stream into memory just once rather than for every header.
- ShpReader.CopyImageData switched to use Array.Copy since that uses some unsafe magic for speed.
- In ActorInfo, cache a GetType call and prevent needless materialization in PrerequisitesOf.
- In ObjectCreator, cache type and ctor lookups since these are expensive and often repeated.
- Implement IReadOnlyDictionary<T, U> on Cache<T, U> to provide some supplementary functions.
- In TechTree.GatherOwnedPrerequisites, rearrange a Boolean 'and' expression to evaluate expensive functions later in the chain, and use ContainsKey to speed up name check.
- Almost all calls to Stream.Read were broken. These have been patched to all go through ReadBytes which itself has been fixed to function correctly. The key thing to note is that Stream.Read is very much allowed to return less than the requested number of bytes. If this happens and you're not checking the return result, you'll be working with partially initialized arrays and really bad stuff happens when you do that.
- Call CopyTo rather than copying between streams manually.
- Peek and ReadUInt8 have been changed to avoid a pointless array allocation which is significant overhead for such simple calls.
- Refactored PerfTimer to use less memory.
- Avoid using the PerfTimer in highly called methods DoTimed and RunActivity, instead tracking long ticks manually to reduce overhead and avoid memory allocations.
- Added some helper methods in PerfTimer to output information when a tick takes too long.
- Changed PerfTimer logging to output the time at the start of the line, and no longer truncate output per line.
- Settings.LongTickThreshold changed from TimeSpan to float and renamed to LongTickThresholdMs.
- Made private methods static where possible (runtime can elide checking the object for null).
- Declared attribute classes as sealed (allows reflection on attributes to complete faster).
- Moved some static cctor's into field initializers (static cctor's are slower than static field initializers).
- Made classes static if they contained only static methods (can't create instances of useless objects).
- Use inferable Exts.Lazy and not new Lazy<T>().
- Added required STAThread attribute to CrashDialog.
- Removed unused parameters in private methods.
- Added Serializable attribute to exceptions.
- Added parameter name in calls to ArgumentNullException.
- Use of as operator instead of is + cast.
- Changed (x as Foo).Bar anti-pattern into ((Foo)x).Bar. Results in sensible cast exceptions on error rather than null dereferences.
- Removed unused method in NullShader.
Targeted some methods that generated allocated a lot of memory in the main game loop:
- Actor.Render - Changed LINQ calls into equivalent loops. No allocation for delegates.
- Animation.Render - Returned an array rather than a yield expression. The array uses less memory than the complier generated enumerable.
- FrozenActor and FrozenUnderFog - Materialize the footprint into an array: The enumerable is not-trivial to evaluate is and evaluated many times inside the Tick function. The memory needed is minimal. Changed LINQ into equivalent loops to prevent delegate allocation. Should result in overall much faster calls.
- Widget.GetEventBounds - Changed LINQ calls into equivalent loops.
- MobileInfo.CanEnterCell - Changed LINQ calls into equivalent loops. Don't materialize list of blocking actors every time, instead enumerate them and only when they need to be checked.
- FrozenUnderFog.TickRender - Generate the renderables lazily and also remove a no-op Select call.
Create a single solution platform named x86.
Ensure both Debug and Release configs build to the root for all projects.
Ensure all Release configs generate pdbs.
Actor, CPos, CVec, WAngle, WPos, WRange, WRot and WVec structs now implement IEquatable<T> which means unboxing/casting costs can be eliminated.
Also simplified the ToString method by concatenating components directly rather than using a format string since the overhead is a bit high for simple cases like this.
* Use Pair instead of KeyValuePair
* double -> var
* Butcher XML comments
* Change WinState default to Undefined and use it instead of the new GameOutcome
* Other changes
It was crashing because it tried to seek 8 bytes before the end
of a file that was empty (zero length).
I also added a few more checks and another try/catch to prevent
any more crashes related to damaged files.
List of changes:
* Better and more filters with new layout, for both mods.
* Rename/Delete/Detele all functionality.
* Simplified ReplayMetadata class considerably by introducing a new
GameInformation data object. The new GameInformation class contains
more information than previously available so the new solution is not
compatible with old replays, meaning it can't read old replays.
* Better and cleaner game information gathering in order to be written
at the end of the replay file.
* Revert changes to ReplayConnection, no longer necessary.
* Better exception message on missing sprites and fonts.
* New "SpawnOccupant" class that holds all the information needed by the
MapPreviewWidget to visualize a spawn point. It was using Session.Client
before and it was necessary to separate it to be able to show information
not available at lobby time.
* Fix keyboard focus UI bug when closing a window would not remove focus.
This closes issue #2152. The filters added are:
* Game type (singleplayer / multiplayer)
* Date
* Duration
* Outcome
* Player name
Other changes:
* Added a 'CollapseHiddenChildren' option to the ScrollPanelWidget to
make hidden children take up no space.
* Removed the extension (.rep) from the replay filenames in the
replay browser.
The replay files are just streams all network communication so to
get any info out of them it is necessary to play back the stream
until the wanted information is reached.
This introduces a new metadata block placed at the end of the
replay files and logic to read the new block, or fall back to
playing back the stream for older files.
The replay browser is also updated to use the metadata information
instead of reading the replay stream directly.
