>From 7.21.5, curl can be tricked into using an open fd.
This series uses this to allow using curl over a tunnel.
I have a few doubt on patch #2:
- is socketpair working on all git supported system (windows ?)
- should socketpair always be used or limited to the curl over tunnel case ?
I don't think there is too much different between an unname pipe and a
socketpair but I'm not sure either :)
This series also shows a "bug" in curl.
When trying out the tunnel example fro imap-send documentation, this happends:
Starting tunnel 'ssh -q -C localhost /usr/sbin/imapd ./Maildir'... ok

It appears curl do not support the PREAUTH tag.
However a test with "nc imap.server.ext 143" is working fine.
Nicolas Morey-Chaisemartin (3):
imap-send: move tunnel setup to its own function
imap-send: use a socketpair instead of pipe to communicate with the
tunnel
imap_send: add support for curl over tunnel
