scenario: you want to remote-control fetchmail, but you don't want to write
passwords into files, so you feed fetchmail a minimal rcfile via stdin with -f
-. this by itself works fine. if you also want or need to use a --plugin (eg.
socat for socks), then things fail badly: the plugin is run without a stdin fd,
hence can't take input from fetchmail, lots of fun ensues. plugins without -f
- work fine, it's just the combination that fails.
explanation: the root cause is rcfile_y.y, line 493, which closes whatever fd
carried the rcfile. with -f - this closes fetchmail's stdin - and so far that's
unproblematic. however, in socket.c lines 166ff things go wrong: fetchmail
sets up the plugin with a socketpair, which will likely include the first
unused fd - and fd zero is now indeed unused. in line 180ff a dup2 replumbing
from "that fd" (=zero) to zero is performed - and then "that fd" is closed.
and hey presto, we've got no fd zero = stdin for the plugin.
solution: the simplest solution (patch attached) is to make the fclose of the
rcfile conditional, ie. don't close if it's stdin. in the long run the
dup2+close code might be made more robust by not doing a dup2+close if fd[0] is
already 0 or 1.

A patch to clear SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS was added recently:
http://gitorious.org/fetchmail/fetchmail/commit/48809c5b9f6c9081f4031fa938dd63b060c18a4b?format=patch
Older implementations of OpenSSL do not support SSL_CTX_clear_options().
This patch reworks the previous change to avoid the use of
SL_CTX_clear_options() and instead clears the corresponding bit in
SSL_OP_ALL before calling SSL_CTX_set_options().

The Python-related Makefile.am parts were simplified to avoid an
automake 1.11.X bug around noinst_PYTHON, Automake Bug #10995.

The GSSAPI-related autoconf code now matches gssapi.c better, and uses
a different check to look for GSS_C_NT_HOSTBASED_SERVICE.
This fixes the GSSAPI-enabled build on NetBSD 6 Beta.

This is to avoid reading from bad locations, and possibly conveying
confidential data. Credit to Nico Golde.

Some servers, for instance the MS Exchange servers deployed by the
US-American National Aeronautics and Space Administration (NASA),
aborted the NTLM protocol exchange after receiving the initial request.
Fetchmail did not detect that there was an error message, rather than
NTLM protocol exchange, and caught a segmentation fault while reading
from a bad location.
Detect base64 decoding errors, and return PS_AUTHFAIL in this case.

treat missing header in response to a FETCH command as a transient error

if there are too many transient errors, log it.

Zimbra occasionally returns this response:
fetchmail: IMAP> A0007 FETCH 1 RFC822.HEADER
fetchmail: IMAP< * 1 FETCH ()
fetchmail: IMAP< A0007 OK FETCH completed
It happens when there is a corrupted message without a header in the
database. (I don't know how this message could be created, I just see it
there).
When fetchmail encounters such resonse, it gives up and disconnects.
This patch changes it so that PS_TRANSIENT is returned in this
case and fetchmail continues to fetch following messages correctly.

On systems where SSLv2_client_method isn't defined in OpenSSL (such as newer
Debian, and Ubuntu starting with 11.10 oneiric ocelot), don't reference it (to
fix the build) and print a run-time error that the OS does not support SSLv2.
Fixes Debian Bug #622054, but note that that bug report has a more thorough
patch that does away with SSLv2 altogether.

This reverts commits 47c05b10018f5ec7493e4bd9f521aaa18d96f1e2
and 72ce8bce8dd655b6aefa33d0a74e883dad5202b5, the code isn't portable,
for instance, Solaris does not support SO_RCVTIMEO/SO_SNDTIMEO.
These socket-level options are known, but Solaris returns EAFNOSUPPORT.
