  • Component set to base
  • Keywords wxFileStream wxFFileStream streams added
  • Priority changed from normal to high
  • Status changed from new to confirmed
  • Summary changed from wxFFileStream is not able to use output stream to wx(F)FileStream is not able to use output stream

There is indeed a bug in wx(F)FileStream ctor: it opens the file using wx(F)FileInputStream ctor which, of course, opens it for reading only and writing to it always fails.

Solution is clear enough: open the file in read/write mode in the ctor and pass pointer to it to both base classes. But I don't have time to do it right now, as even though it's a simple change it still needs to be tested.

Increasing the priority though as it's embarassing to have such a simple class completely broken.

  • Milestone set to 2.8.9
  • Resolution set to port to stable
  • Status changed from confirmed to portneeded

Fixed in the trunk as r54246, should be backported to 2.8 later (the new argument of wxFFileStream could be omitted entirely or added inside wxABI_VERSION check).
