file_truncate(): C doesn't define what fflush(fp) does if fp is open for update, and the preceding I/O operation on fp was input. On Windows, fflush() actually changes the current file position then. Because Windows doesn't support ftruncate() directly, this not only caused Python's file.truncate() to change the file position (contra our docs), it also caused the file not to change size. Repaired by getting the initial file position at the start, restoring it at the end, and tossing all the complicated micro-efficiency checks trying to avoid "provably unnecessary" seeks. file.truncate() can't be a frequent operation, and seeking to the current file position has got to be cheap anyway. Bugfix candidate. |
