Check return value of calls to File::CreateTempDir() from CoreTiming,
FileSystem, and MMIO test classes to verify the test user directory
exists, and fail the tests otherwise.
Adds a flag to File::Delete and File::DeleteDir functions to control
whether a console warning is emitted when the file or directory doesn't
exist. The flag is optional and true by default to match current behavior.
Makes File::DeleteDir return true when attempting to delete a
nonexistent path.
The purpose of DeleteDir is to ensure the path doesn't exist after the
call, which is better reflected by the new return value. Additionally,
none of the current callers actually check the return value so this
won't break any existing code.
/Externals/liblzma/config.h #defines HAVE_PTHREAD_CONDATTR_SETCLOCK
which results in /Externals/liblzma/tuklib/mythread.h calling the
function pthread_condattr_setclock. This function doesn't exist in
macOS 10.12+, which are the only macOS versions Dolphin supports, but
inserting an include guard makes macOS use an alternate function.
On Windows, when the Rename function fails to replace an existing file
it will now retry the operation multiple times with increasingly long
delays between attempts. This fixes transient rename failures.
I've been getting sporadic yet annoyingly frequent errors saying:
'IOS_FS: Failed to rename temporary FST file'
These typically appear on startup but I've also gotten them randomly.
Investigation shows this happens when the Windows ReplaceFile function
returns the error ERROR_UNABLE_TO_REMOVE_REPLACED. That happens in the
context of using ReplaceFile to perform an atomic file overwrite, which
is required when saving updates to a file to avoid corruption. The
error mainly happens with the /Wii/fst.bin file but I've seen it
happen with multiple other files as well.
I haven't been able to definitively pin down why the error occurs,
though online discussions suggest antivirus scanning may be a major
culprit. That said, I've excluded the Dolphin folder from Windows
Defender scans to no avail and don't have any other antivirus running,
so this is likely to be a problem others are experiencing as well.
The number and duration of retry delays is arbitrary but I feel like a
combined second or so in the worst case is an acceptable tradeoff for
the reduction (actually elimination in my experience) of those errors.
This is even more true when you consider the time it takes to read and
dismiss the error dialogs.
