The reallocation was using the input pointer for the return value, which
leads to a memory leak on reallication failure. Fix by instead use the
safe internal API call Curl_saferealloc().

ftp_send_command() was using vsnprintf() without including the libcurl
*rintf() replacement header. Fix by including curl_printf.h and also
add curl_memory.h while at it since memdebug.h depends on it.

The failf() macro is the name used for invoking Curl_failf(). While
there isn't a way to turn off failf like there is for infof, but it's
still a good idea to use the macro.

Strings broken on multiple rows in the .c file need to have appropriate
whitespace padding on either side of the concatenation point to render
a correct amalgamated string. Fix by adding a space at the occurrences
found.

Commit 8238ba9c5f10414a88f502bf3f5d5a42d632984c inadvertently removed
the actual command to be sent from the send buffer in a refactoring.
Add back copying the command into the buffer. Also add more guards
against malformed input while at it.

- Use memcpy instead of strncpy to copy a string without termination,
since gcc8 warns about using strncpy to copy as many bytes from a
string as its length.

If the formatting fails, we error out on a fatal error and
clean up on the way out. The array was however freed within
the wrong scope and was thus never freed in case the cookies
were written to a file instead of STDOUT.

Expired cookies have already been purged at a later expiration time
before this check, so remove the redundant check.

Sometimes it may be considered a security risk to load an external
OpenSSL configuration automatically inside curl_global_init(). The
configuration option --disable-ssl-auto-load-config disables this
automatism. The Windows build scripts winbuild/Makefile.vs provide a
corresponding option ENABLE_SSL_AUTO_LOAD_CONFIG accepting a boolean
value.
Setting neither of these options corresponds to the previous behavior
loading the external OpenSSL configuration automatically.

... and add "MAILINDEX".
As described in #2789, this is a suggested solution. Changing UID=xx to
actually get mail with UID xx and add "MAILINDEX" to get a mail with a
special index in the mail box (old behavior). So MAILINDEX=1 gives the
first non deleted mail in the mail box.

Long live CURLE_PEER_FAILED_VERIFICATION
|
|
CURLE_PEER_FAILED_VERIFICATION makes more sense because Curl_parseX509
does not allocate memory internally as its first argument is a pointer
to the certificate structure. The same error code is also returned by
Curl_verifyhost when its call to Curl_parseX509 fails so the change
makes error handling more consistent.
|
|
Failure to extract the issuer name from the server certificate should
return a more specific error code like on other TLS backends.
