- David McCreedy did NTLM changes mainly for non-ASCII platforms:
#1 There's a compilation error in http_ntlm.c if USE_NTLM2SESSION is NOT defined. I noticed this while testing various configurations. Line 867 of the current http_ntlm.c is a closing bracket for an if/else pair that only gets compiled in if USE_NTLM2SESSION is defined. But this closing bracket wasn't in an #ifdef so the code fails to compile unless USE_NTLM2SESSION was defined. Lines 198 and 140 of my patch wraps that closing bracket in an #ifdef USE_NTLM2SESSION. #2 I noticed several picky compiler warnings when DEBUG_ME is defined. I've fixed them with casting. By the way, DEBUG_ME was a huge help in understanding this code. #3 Hopefully the last non-ASCII conversion patch for libcurl in a while. I changed the "NTLMSSP" literal to hex since this signature must always be in ASCII. Conversion code was strategically added where necessary. And the Curl_base64_encode calls were changed so the binary "blobs" http_ntlm.c creates are NOT translated on non-ASCII platforms.

- David McCreedy did NTLM changes mainly for non-ASCII platforms:
|
||||
|
||||
#1
|
||||
There's a compilation error in http_ntlm.c if USE_NTLM2SESSION is NOT
|
||||
defined. I noticed this while testing various configurations. Line 867 of
|
||||
the current http_ntlm.c is a closing bracket for an if/else pair that only
|
||||
gets compiled in if USE_NTLM2SESSION is defined. But this closing bracket
|
||||
wasn't in an #ifdef so the code fails to compile unless USE_NTLM2SESSION was
|
||||
defined. Lines 198 and 140 of my patch wraps that closing bracket in an
|
||||
#ifdef USE_NTLM2SESSION.
|
||||
|
||||
#2
|
||||
I noticed several picky compiler warnings when DEBUG_ME is defined. I've
|
||||
fixed them with casting. By the way, DEBUG_ME was a huge help in
|
||||
understanding this code.
|
||||
|
||||
#3
|
||||
Hopefully the last non-ASCII conversion patch for libcurl in a while. I
|
||||
changed the "NTLMSSP" literal to hex since this signature must always be in
|
||||
ASCII.
|
||||
|
||||
Conversion code was strategically added where necessary. And the
|
||||
Curl_base64_encode calls were changed so the binary "blobs" http_ntlm.c
|
||||
creates are NOT translated on non-ASCII platforms.

- Converted (most of) the test data files into genuine XML. A handful still
|
||||
are not, due mainly to the lack of support for XML character entities
