Change TAEF nuget package to use new Microsoft.Taef name; Update to 10.58 release build version.
## PR Checklist
* [x] Closes email from Phil letting us know TAEF has a new release build and a rename.
* [x] Closes annoying duplicate TAEF import warning in `Parser.UnitTests.vcxproj`
* [x] I work here.
* [ ] Need to see the tests run off CI to confirm this is fine for those environments and Helix
## Validation Steps Performed
* [x] Build/run tests locally
* [ ] Build/run unit and feature tests in CI
* [ ] Build/run Helix-lab tests in CI
I was looking at conhost/OpenConsole and noticed it was being pretty
inefficient with allocations due to some usages of std::deque and
std::vector that didn't need to be done quite that way.
So this uses std::vector for the TextBuffer's storage of ROW objects,
which allows one allocation to contiguously reserve space for all the
ROWs - on Desktop this is 9001 ROW objects which means it saves 9000
allocations that the std::deque would have done. Plus it has the
benefit of increasing locality of the ROW objects since deque is going
to chase pointers more often with its data structure.
Then, within each ROW there are CharRow and ATTR_ROW objects that use
std::vector today. This changes them to use Boost's small_vector, which
is a variation of vector that allows for the so-called "small string
optimization." Since we know the typical size of these vectors, we can
pre-reserve the right number of elements directly in the
CharRow/ATTR_ROW instances, avoiding any heap allocations at all for
constructing these objects.
There are a ton of variations on this "small_vector" concept out there
in the world - this one in Boost, LLVM has one called SmallVector,
Electronic Arts' STL has a small_vector, Facebook's folly library has
one...there are a silly number of these out there. But Boost seems like
it's by far the easiest to consume in terms of integration into this
repo, the CI/CD pipeline, licensing, and stuff like that, so I went with
the boost version.
In terms of numbers, I measured the startup path of OpenConsole.exe on
my dev box for Release x64 configuration. My box is an i7-6700k @ 4
Ghz, with 32 GB RAM, not that I think machine config matters much here:
| | Allocation count | Allocated bytes | CPU usage (ms) |
| ------ | ------------------- | ------------------ | -------------- |
| Before | 29,461 | 4,984,640 | 103 |
| After | 2,459 (-91%) | 4,853,931 (-2.6%) | 96 (-7%) |
Along the way, I also fixed a dynamic initializer I happened to spot in
the registry code, and updated some docs.
## Validation Steps Performed
- Ran "runut", "runft" and "runuia" locally and confirmed results are
the same as the main branch
- Profiled the before/after numbers in the Visual Studio profiler, for
the numbers shown in the table
