3270 :: MemFiles on win32 and win64

• jlp765 (orginal) [2017-10-22T06:36:16+02:00] view original

  For memfiles, I believe there are issues on windows platform with trying to open a file again after a close.

  (just scoping the size of the problem before raising a PR)

  Can someone please test this on win32? (I know it fails on win64)

  Also test with/without the compiler setting -d:release

  
  import os, memfiles, times
  
  proc runTst1(fname: string) =
    var
      file = memfiles.open(fname, fmRead)
      i = 0
      t0 = epochTime()
    for field in lines(file):
      inc(i)
    memfiles.close(file)
    echo "Read lines ", i, " lines! ", epochTime() - t0
  
  proc main() =
    if paramCount() < 1:
      quit("ERROR: Please provide a file name for read testing")
    runTst1(paramStr(1))
    runTst1(paramStr(1))
  main()
  
  Run

  I have submitted PR 6534

  It still has a problem when -d:release is set (at least on win64) because the gcc flag -O3 (or -O1 or -O2) causes some sort of mapping failure.
