Unignored files are marked as conflicting while scanning, which is then resolved
in the subsequent pull. Automatically reconciles needed items on send-only
folders, if they do not actually differ except for internal metadata.
This doesn't happen today, but it might in the future if the block size
were increased or made variable and we were talking to a client from the
future.
The current 500 "test failed" looks and sounds like a problem in the
relay pool server, while it actually indicates a problem on the
announcing side. Instead use 400 "connection test failed" to indicate
that the request was bad and what was the test.
* lib/db: Don't panic on negative counts (fixes#4659)
So, negative counts should never happen and hence the original idea to
panic. However, this sucks as the panic will happen in a folder runner,
be automatically swallowed by suture, and the runner gets restarted but
now we are in a bad state. (Related: #4758)
At the time of writing the global list is somewhat in flux (we've
changed how ignored files are handled, invalid bits, etc.) and I think
that can cause unusual conditions here. Hence just fixing up the numbers
instead until the next full recount.
* release:
lib/osutil: Fix priority lowering on Windows
lib/osutil: Don't attempt to reduce our niceness level (fixes#4681)
lib/osutil: Check PGID before trying to set it (fixes#4679)
When scanner.Walk detects a change, it now returns the new file info as well as the old file info. It also finds deleted and ignored files while scanning.
Also directory deletions are now always committed to db after their children to prevent temporary failure on remote due to non-empty directory.
This removes a number of timing related things, leaving just the total
test timeout now bumped to one minute. Normally we get the filesystem
events within a second or so, so this doesn't affect the test time in
the successfull case. If we don't actually get the events we expect
within a minute I think we are legitimately in "failed" territory.
