Antoine Pitrou ee46a7bf9c Issue #12062: In the `io` module, fix a flushing bug when doing a certain 
type of I/O sequence on a file opened in read+write mode (namely: reading,
seeking a bit forward, writing, then seeking before the previous write but
still within buffered data, and writing again).

  Issue #10478: Reentrant calls inside buffered IO objects (for example by
  way of a signal handler) now raise a RuntimeError instead of freezing the
  current process.

  Issue #9550: a BufferedReader could issue an additional read when the
  original read request had been satisfied, which can block indefinitely
  when the underlying raw IO channel is e.g. a socket.  Report and original
  patch by Jason V. Miller.

Antoine Pitrou f7fd8e4c94 Issue #7865: The close() method of :mod:`io` objects should not swallow 
exceptions raised by the implicit flush().  Also ensure that calling
close() several times is supported.  Patch by Pascal Chambon.

Benjamin Peterson ddd392cbb9 accept None as the same as having passed no argument in file types #7349 
This is for consistency with imitation file objects like StringIO and BytesIO.

This commit also adds a few tests, where they were lacking for concerned
methods.

Mark Dickinson 889d96455a Issue #7228: Fix format mismatch when printing something of type off_t. 
(Should silence some compiler warnings.)

Antoine Pitrou e50efaad9f Buffered I/O: optimize lock taking in the common non-contended case. 2009-11-01 11:58:22 +00:00
Mark Dickinson 3ddb52717f Roll back ill-considered attempts to fix printf specifier mismatch for off_t. 
The sensible solution seems to be to implement %lld for PyString_FromFormat(V)
and PyErr_Format.  See issue #7228.

Mark Dickinson bf1039d98c Silence gcc warnings when trying to print an off_t using "lld", on platforms 
where off_t has type long (e.g., 64-bit Linux).
 2009-10-27 21:48:20 +00:00
Mark Dickinson e052b64def Use correct conversion specifier and length modifier when printing an 
integer of type off_t.  Also, don't assume that long long is available.

Antoine Pitrou 20e1f932fa Issue #6629: Fix a data corruption issue in the new `io` package, which could 
occur when writing to a BufferedRandom object (e.g. a file opened in "rb+" or
"wb+" mode) after having buffered a certain amount of data for reading. This
bug was not present in the pure Python implementation.

Yes, this is a serious issue.
