New submission from Cyril <c...@excellency.fr>: ssl.SSLSocket.write on non-blocking sockets will fail with:
_ssl.c:1217: error:1409F07F:SSL routines:SSL3_WRITE_PENDING:bad write retry on a write retry, if the buffer address has changed between the initial call and the retry (when the initial call returned 0 bytes written, which means you should try again later). >From OpenSSL docs (http://www.openssl.org/docs/ssl/SSL_CTX_set_mode.html): SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Make it possible to retry SSL_write() with changed buffer location (the buffer contents must stay the same). This is not the default to avoid the misconception that non-blocking SSL_write() behaves like non-blocking write(). Attached patch fixes the problem (tested on Python 2.6.5, 2.7 trunk) by calling SSL_CTX_set_mode with SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER. It's a single line patch. ---------- components: Library (Lib) files: _ssl.c.patch keywords: patch messages: 101753 nosy: cbay severity: normal status: open title: ssl.SSLSocket.write may fail on non-blocking sockets versions: Python 2.6, Python 2.7 Added file: http://bugs.python.org/file16668/_ssl.c.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue8240> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
