230c09c06a imap-send.c: set CURLOPT_USE_SSL to CURLUSESSL_TRY
According to the cURL documentation for the CURLOPT_USE_SSL option,
it is only used with plain text protocols that get upgraded to SSL
using the STARTTLS command.

The server.use_ssl variable is only set when we are using a protocol
that is already SSL/TLS (i.e. imaps), so setting CURLOPT_USE_SSL
when the server.use_ssl variable is set has no effect whatsoever.

Instead, set CURLOPT_USE_SSL to CURLUSESSL_TRY when the server.use_ssl
variable is NOT set so that cURL will attempt to upgrade the plain
text connection to SSL/TLS using STARTTLS in that case.

This much more closely matches the behavior of the non-cURL code path.

d47e55da92 imap-send.c: support GIT_CURL_VERBOSE
When using git-imap-send to send via cURL, support setting
the GIT_CURL_VERBOSE environment variable to enable cURL's
verbose mode.

The existing http.c code already supports this and does
it by simply checking to see whether or not the environment
variable exists -- it does not examine the value at all.

For consistency, enable CURLOPT_VERBOSE when GIT_CURL_VERBOSE
is set by using the exact same test that http.c does.

1e16b255b9 git-imap-send: use libcurl for implementation
Use libcurl's high-level API functions to implement git-imap-send
instead of the previous low-level OpenSSL-based functions.

Since version 7.30.0, libcurl's API has been able to communicate with
IMAP servers. Using those high-level functions instead of the current
ones would reduce imap-send.c by some 1200 lines of code. For now,
the old ones are wrapped in #ifdefs, and the new functions are enabled
by make if curl's version is >= 7.34.0, from which version on curl's
CURLOPT_LOGIN_OPTIONS (enabling IMAP authentication) parameter has been
available. The low-level functions will still be used for tunneling
into the server for now.

As I don't have access to that many IMAP servers, I haven't been able to
test the new code with a wide variety of parameter combinations. I did
test both secure and insecure (imaps:// and imap://) connections and
values of "PLAIN" and "LOGIN" for the authMethod.

In order to suppress a sparse warning about "using sizeof on a
function", we use the same solution used in commit 9371322a6
("sparse: suppress some "using sizeof on a function" warnings",
06-10-2013) which solved exactly this problem for the other commands
using libcurl.

e0d8e3084f imap-send: create target mailbox if it is missing
Some MUAs delete their "drafts" folder when it is empty, so
git imap-send should be able to create it if necessary.

This change checks that the folder exists immediately after
login and tries to create it if it is missing.

There was some vestigial code to handle a [TRYCREATE] response
from the server when an APPEND target is missing. However this
code never ran (the create and trycreate flags were never set)
and when I tried to make it run I found that the code had already
thrown away the contents of the message it was trying to append.

  i == 0 correctly.

* Make the two loops over the string look as similar as possible to
  make it more obvious that the count computed in the first pass
  agrees with the true length of the new string written in the second
  pass.  As a side effect, this makes it possible to use the "j"

118a68f9dd wrap_in_html(): process message in bulk rather than line-by-line
Now that we can xml-quote an arbitrary string in O(N), there is no
reason to process the message line by line.  This change saves lots of
memory allocations and copying.

The old code would have created invalid output when there was no
body, emitting a closing </pre> without a blank line nor an opening
<pre> after the header.  The new code simply returns in this
situation without doing harm (even though either would not make much
sense in the context of imap-send that is meant to send out patches).

f035ab6205 imap-send: change msg_data from storing (ptr, len) to storing strbuf
struct msg_data stored (ptr, len) of the data to be included in a
message, kept the character data NUL-terminated, etc., much like a
strbuf would do.  So change it to use a struct strbuf.  This makes
the code clearer and reduces copying a little bit.

A side effect of this change is that the memory for each message is
freed after it is used rather than leaked, though that detail is
unimportant given that imap-send is a top-level command.

By the way, there is a bunch of infrastructure in this file for
dealing with IMAP flags, although there is nothing in the code that
actually allows any flags to be set.  If there is no plan to add
support for flags in the future, a bunch of code could be ripped out
and "struct msg_data" could be completely replaced with strbuf, but
that would be a separate topic.

6360bee4cd imap-send: correctly report errors reading from stdin
Previously, read_message() didn't distinguish between an error and eof
when reading its input.  This could have resulted in incorrect
behavior if there was an error: (1) reporting "nothing to send" if no
bytes were read or (2) sending an incomplete message if some bytes
were read before the error.

Change read_message() to return -1 on ferror()s and 0 on success, so
that the caller can recognize that an error occurred.  (The return
value used to be the length of the input read, which was redundant
because that is already available as the strbuf length.

Change the caller to report errors correctly.

3a34e62684 imap-send: store all_msgs as a strbuf
all_msgs is only used as a glorified string, therefore there is no
reason to declare it as a struct msg_data.

32a8569ecf lf_to_crlf(): NUL-terminate msg_data::data
Through the rest of the file, the data member of struct msg_data is
kept NUL-terminated, and that fact is relied upon in a couple of
places.  Change lf_to_crlf() to preserve this invariant.

In fact, there are no execution paths in which lf_to_crlf() is called
and then its data member is required to be NUL-terminated, but it is
better to be consistent to prevent future confusion.

Document the invariant in the struct msg_data definition.
