The destructor for SignPostEmitterImpl::SignpostLog is known statically. Avoid
the unnecessary vtable indirection through std::function in the std::unique_ptr
by turning LogDeleter into a struct. No real functionality change here.

Support: Drop the no-op initializer for SignpostEmitterImpl::Signposts, NFC

This is a DenseMap, which has its own initializer; we don't need to explicitly
call the default constructor here.

6 days agoSupport: Extract fs::resize_file_before_mapping_readwrite from FileOutputBuffer
Duncan P. N. Exon Smith [Wed, 27 Jan 2021 00:01:36 +0000 (16:01 -0800)]
Support: Extract fs::resize_file_before_mapping_readwrite from FileOutputBuffer

Add a variant of `fs::resize_file` for use immediately before opening a
file with `mapped_file_region::readwrite`. On Windows, `_chsize`
(`ftruncate`) is slow, but `CreateFileMapping` (`mmap`) automatically
extends the file so the call to `fs::resize_file` can be skipped.

This optimization was added to `FileOutputBuffer` in
da9bc2e56d5a5c6332a9def1a0065eb399182b93; this commit just extracts the
logic out and adds a unit test.
