  • mto: This revision was merged to the branch mainline in revision 3449.
  • Revision ID: eholmberg@arrow.com-20080506150227-l3arq1yntdvnoxum
Fix for Bug #215426 in which bzr can cause a MemoryError in socket.recv while
downloading large packs over http.  This patch limits the request size for
socket.recv to avoid this problem.

Changes:
Added mock file object bzrlib.tests.file_utils.
Added new parameters to bzrlib.osutils.pumpfile.
Added unit tests for bzrlib.osutils.pumpfile.
Added usage of bzrlib.osutils.pumpfile to bzrlib.transport.http.response.
