Upcoming OpenSSL 1.1.0 will break compilation b updating a few APIs
we use in imap-send, which has been adjusted for the change.
* ky/imap-send-openssl-1.1.0:
configure: remove checking for HMAC_CTX_cleanup
imap-send: avoid deprecated TLSv1_method()
imap-send: check NULL return of SSL_CTX_new()
imap-send: use HMAC() function provided by OpenSSL
|

Remove extra + 1 from resp_len, the length of the byte sequence to be
Base64 encoded and passed to the server as the response. Or the response
incorrectly contains an extra \0.

Don't check for NOLOGIN (LOGINDISABLED) capability when imap.authMethod
is specified.
LOGINDISABLED capability doesn't forbid using AUTHENTICATE, so it should
be allowed, or we can't connect to IMAP servers which only accepts
AUTHENTICATE command.

Use SSLv23_method always and disable SSL if needed.
TLSv1_method() function is deprecated in OpenSSL 1.1.0 and the compiler
emits a warning.
SSLv23_method() is also deprecated, but the alternative, TLS_method(),
is new in OpenSSL 1.1.0 so requires checking by configure. Stick to
SSLv23_method() for now (this is aliased to TLS_method()).

Fix compile errors with OpenSSL 1.1.0.
HMAC_CTX is made opaque and HMAC_CTX_cleanup is removed in OpenSSL
1.1.0. But since we just want to calculate one HMAC, we can use HMAC()
here, which exists since OpenSSL 0.9.6 at least.

We frequently allocate strings as xmalloc(len + 1), where
the extra 1 is for the NUL terminator. This can be done more
simply with xmallocz, which also checks for integer
overflow.
There's no case where switching xmalloc(n+1) to xmallocz(n)
is wrong; the result is the same length, and malloc made no
guarantees about what was in the buffer anyway. But in some
cases, we can stop manually placing NUL at the end of the
allocated buffer. But that's only safe if it's clear that
the contents will always fill the buffer.
In each case where this patch does so, I manually examined
the control flow, and I tried to err on the side of caution.

It's a common pattern to do:
foo = xmalloc(strlen(one) + strlen(two) + 1 + 1);
sprintf(foo, "%s %s", one, two);
(or possibly some variant with strcpy()s or a more
complicated length computation). We can switch these to use
xstrfmt, which is shorter, involves less error-prone manual
computation, and removes many sprintf and strcpy calls which
make it harder to audit the code for real buffer overflows.

not force the user to add --curl to get a working git imap-send

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.

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.

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.

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.

Most struct child_process variables are cleared using memset first after
declaration. Provide a macro, CHILD_PROCESS_INIT, that can be used to
initialize them statically instead. That's shorter, doesn't require a
function call and is slightly more readable (especially given that we
already have STRBUF_INIT, ARGV_ARRAY_INIT etc.).

git-imap-send was directly prompting for a password rather than using

This is a necessary improvement for users that use two factor authentication, as

Leaving only the function definitions and declarations so that any
new topic in flight can still make use of the old functions, replace
existing uses of the prefixcmp() and suffixcmp() with new API
functions.
The change can be recreated by mechanically applying this:
$ git grep -l -e prefixcmp -e suffixcmp -- \*.c |
grep -v strbuf\\.c |
xargs perl -pi -e '
s|!prefixcmp\(|starts_with\(|g;
s|prefixcmp\(|!starts_with\(|g;
s|!suffixcmp\(|ends_with\(|g;
s|suffixcmp\(|!ends_with\(|g;

* The first character in the string used to be special-cased to get
around the fact that msg->buf[i - 1] is not defined for i == 0.
Instead, keep track of the previous character in a separate
variable, "lastc", initialized in such a way to let the loop handle
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"
counter in place of lfnum and new_len.

They are unused, and their removal means that a bunch of list-related
infrastructure can be disposed of.
It might be that the "NAMESPACE" response that is now skipped over in
get_cmd_result() should never be sent by the server. But somebody
would have to check the IMAP protocol and how we interact with the
server to be sure. So for now I am leaving that branch of the "if"
