[PATCH 1/8] imap-send: remove useless uid code

[PATCH 1/8] imap-send: remove useless uid code

[Erik Faye-Lund]

From: Jeff King <peff@peff.net>

The imap-send code is based on code from isync, a program
for syncing imap mailboxes. Because of this, it has
inherited some code that makes sense for isync, but not for
imap-send.

In particular, when storing a message, it does one of:

  - if the server supports it, note the server-assigned
    unique identifier (UID) given to each message

  - otherwise, assigned a random UID and store it in the
    message header as X-TUID

Presumably this is used in isync to be able to synchronize
mailstores multiple times without duplication. But for
imap-send, it the values are useless; we never do anything
with them and simply forget them at the end of the program.

This patch removes the useless code. Not only is it nice for
maintainability to get rid of dead code, but the removed
code relied on the existence of /dev/urandom, which made it
a portability problem for non-Unix platforms.

definition (i.e the one from mmsystem.h) before defining DRV_OK.

[PATCH 6/8] mingw: wrap SSL_set_(w|r)fd to call _get_osfhandle

[Erik Faye-Lund]

SSL_set_fd (and friends) expects a OS file handle on Windows, not
a file descriptor as on UNIX(-ish).

This patch makes the Windows version of SSL_set_fd behave like the
UNIX versions, by calling _get_osfhandle on it's input.

It shouldn't be necessary to check whether DRV_OK is defined before undefining
it; if it's not defined, undefining it will be a NOP.

Heya,

easier for those that were not following the series to drop in at the
current version (assuming you provide a short summary of what the
series is about in the cover letter)..

Doh, I'm sorry about this. Here's an added cover-letter, I hope it helps:

--->8---
Here's the 2nd iteration of my patches  for Windows-compatibility in imap-send.

Patch 1-3 is about getting rid of or rewriting code with portability issues.

Patch 4 fixes a compilation error on Windows

Patch 5 enables compilation of imap-send

Patch 6-7 enables SSL-suport for mingw

Patch 8 enables imap-send and SSL for msvc

Changes in this iteration compared to the previous are as follows:

 - Patch 7 has been replaced with patch 1 in the current series. All
other patches from the previous iteration has been shifted up a number
due to this.
 - Patch 2 (previously 1) now has a short comment that declares it's intent.
 - Patch 8 has been included

On the third line of this paragraph, "it" should be removed.
