      X wcfs: test: Register tFile to tDB early · 91e9eba8
      Kirill Smelkov authored
      tFile registers itself to tDB so that defer(tdb.close) that each test does,
      automatically close all files before trying to unmount wcfs. However if an
      error happens inside tFile constructor - before the place where
      `tdb._files.add(t)` was previously located, tDB.close won't close tFile.f,
      which will leave opened file on the wcfs -> wcfs unmount will fail with EBUSY,
      and wcfs will be killed with huge backtrace.
      
      If we register tFile early, the problem - even if it happens inside tFile
      constor - will be handled gracefully: opened file closed and wcfs unmounted
      clearnly - for example with the following short and easy to understand traceback

      X fix test.go for mod build · e159a912
      Kirill Smelkov authored
      go.mod is inside wcfs/ and if `go test ./...` is ran outside of it, it
      autodetects to use GOPATH mode and fails to find imports used by wcfs.
