UWP doesn't allow reading regkeys #594

LoadLibrary · 2020-01-13T21:41:01Z

UWP doesn't allow reading regkeys. Unfortunately, UWP also doesn't offer an API for returning nominal processor frequency at this moment. Other options would require apps depending on abseil-cpp to be packaged with extra manifest data or libraries for bridging platforms.

This change pushes the unsupported APIs accessing the registry behind a define guard. This define guard makes GetNominalCPUFrequency to compile and run as usual on desktop, but it will return the value 1.0 on UWP Apps (Store).

Fixes: #593

Hi guys, I have another issue:
In SOURCE/absl/debugging/symbolize_win32.inc function InitializeSymbolizer and Symbolize, there are functions SymSetOptions and SymFromAddr which are not supported under uwp[1][2].
So I simply disabled them: return directly or return false[3].
Is this acceptable?

[2]. DbgHelp.h Line 30:

#if WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_DESKTOP | WINAPI_PARTITION_PKG_WER)

[3]. #10301

@JackBoosY The purpose of this PR is to fix the abseil build used by WebRTC for UWP. WINAPI_PARTITION_PKG_WER is not the right way to gate code based on UWP/Desktop partitions. Feel free to file another bug and post a different PR to fix SOURCE/absl/debugging/symbolize_win32.inc.

@LoadLibrary Okay, but I'm not sure my changes is correct.
