Following the addition of informational commands to the SMTP protocol,
the test server is no longer required to return the verified server
information in responses that curl only outputs in verbose mode.
Instead, a similar detection mechanism to that used by FTP, IMAP and
POP3 can now be used.
This commit replaces that of 9f260b5d66 because according to RFC-2449,
section 6, there is no APOP capability "...even though APOP is an
optional command in [POP3]. Clients discover server support of APOP by
the presence in the greeting banner of an initial challenge enclosed in
angle brackets."
SASL downgrade tests: 833, 835, 879, 881, 935 and 937 would fail as
they contained a minus sign in their authentication mechanism and this
would be missed by the custom reply parser.
Added support for downgrading the SASL authentication mechanism when the
decoding of CRAM-MD5, DIGEST-MD5 and NTLM messages fails. This enhances
the previously added support for graceful cancellation by allowing the
client to retry a lesser SASL mechanism such as LOGIN or PLAIN, or even
APOP / clear text (in the case of POP3 and IMAP) when supported by the
server.
To avoid the regression when users pass in passwords containing semi-
colons, we now drop the ability to set the login options with the same
options. Support for login options in CURLOPT_USERPWD was added in
7.31.0.
Test case 83 was modified to verify that colons and semi-colons can be
used as part of the password when using -u (CURLOPT_USERPWD).

A failure during authentication, which is performed as part of the
CONNECT phrase (for IMAP, POP3 and SMTP) is considered by the multi-
interface as being closed prematurely (aka a dead connection). As such
these protocols cannot issue the relevant QUIT or LOGOUT command.
Temporarily fixed the test cases until we can fix this properly.
The error code should not be sent as data as it isn't passed onto the
client as body data, so cannot be compared in the test suite against
expected data.
Although this option should have already been set, the SMTP module can
now download information from and send instructional commands to, an
SMTP server, requiring the option to be set in order to perform a mail
transfer.
As the IMAP regex could fail and $1 would not contain the command id
updated the unrecognised command response to be more generic and
realistic (like those used in the command handlers).
Additionally updated the POP3, SMTP and FTP responses.
A base64 string should be a multiple of 4 characters in length, not
contain any more than 2 padding characters and only contain padding
characters at the end of string. For example: Y3VybA==
Strings such as the following are considered invalid:
Y= - Invalid length
Y== - Invalid length
Y=== - More than two padding characters
Y=x= - Padding character contained within string
This is a regression since the switch to always-multi internally
c43127414d.
Test 1316 was modified since we now clearly call the Curl_client_write()
function when doing the LIST transfer part and then the
handler->protocol says FTP and ftpc.transfertype is 'A' which implies
text converting even though that the response is initially a HTTP
CONNECT response in this case.
As the URI, which is contained within the DIGEST-MD5 response, is
constructed from the service and realm, the encoded message differs
from that generated under POP3.
...as it is no longer required following capability and authentication
changes and is now causing problems following commit 49341628b5 as
the test number is obtained from the client address in the EHLO.
...to the client address as this frees the RCPT strings to contain
just an email address and by passing the test number into curl as the
client address remains consistent with POP3 and IMAP tests as they are
specified in the URL.
As someone reported on the mailing list a while back, the hard-coded
arbitrary timeout of 7s in test 1112 is not sufficient in some build
environments. At Arista Networks we build and test curl as part of our
automated build system, and we've run into this timeout 170 times so
far. Our build servers are typically quite busy building and testing a
lot of code in parallel, so despite being beefy machines with 32 cores
and 128GB of RAM we still hit this 7s timeout regularly.
URL: http://curl.haxx.se/mail/lib-2010-02/0200.html
As curl will send a HELO command after an negative EHLO response, added
the same detection from commit b07709f741 to the HELO handler to
ensure the test server is identified correctly and an upload isn't
performed.
Rather than detecting the TO address as missing in the DATA handler,
moved the detection to the RCPT command handler where an error response
can be generated.
Moved the special SMTP server detection code from the DATA command
handler, which happens further down the operation chain after EHLO,
MAIL and RCPT commands, to the EHLO command as it is the first command
to be generated by a SMTP operation as well as containing the special
"verifiedserver" string from the URL.
This not only makes it easier and quicker to detect but also means that
cURL doesn't need to specify "verifiedserver" as --mail-from and
--mail-rcpt arguments.
More importantly, this also makes the upcoming verification changes to
the RCPT handler easier to implement.
The libcurl date parser returns INT_MAX for all dates > 2037 so this
test is now made to use 2037 instead of 2038 to work the same for both
32bit and 64bit time_t systems.
Following changes to ftpserver.pl fixed the mail from address to be a
correctly formatted address otherwise the server response will be 501
Invalid address.
MAIl_smtp() will now check for a correctly formatted FROM address as
well as the optional SIZE parameter comparing it against the server
capability when specified.
Implement: Expired Cookies These following situation, curl removes
cookie(s) from struct CookieInfo if the cookie expired.
- Curl_cookie_add()
- Curl_cookie_getlist()
- cookie_output()
Renamed SUPPORTAUTH to AUTH and added support for specifying a list of
supported SASL mechanisms to return to the client.
Additionally added the directive to the FILEFORMAT document.
Renamed SUPPORTCAPA to CAPA and added support for specifying a list of
supported capabilities to return to the client.
Additionally added the directive to the FILEFORMAT document.
The message numbers given in the LIST response are an index into the
list, which are only valid for the current session, rather than being a
unique message identifier. An index would only be missing from the LIST
response if a DELE command had been issued within the same session and
had not been committed by the end of session QUIT command. Once
committed the POP3 server will regenerate the message numbers in the
next session to be contiguous again. As such our LIST response should
list message numbers contiguously until we support a DELE command in the
same session.
Should a POP3 user require the unique message ID for any or all
messages then they should use the extended UIDL command. This command
will be supported by the test ftpserver in an upcoming commit.
Corrected the call to logmsg() in the IMAP SEARCH handler from commit
4ae7b7ea69 as it should have been outputting the what argument and
not the test number.
The specified curl binary will then be used to verify the running
server(s) instead of the development version. This is very useful in
some cases when the development version fails to verify correctly as
then the test case may not run at all.
The actual test will still be run with the "normal" curl executable
(unless the test case specifies something differently).
... this also makes sure that the progess callback gets called more
often during TFTP transfers.
Added test 1238 to verify.

This function is meant to work *exactly* as curl_easy_perform() but will
use the event-based libcurl API internally instead of
curl_multi_perform(). To avoid relying on an actual event-based library
and to not use non-portable functions (like epoll or similar), there's a
rather inefficient emulation layer implemented on top of Curl_poll()
instead.
There's currently some convenience logging done in curl_easy_perform_ev
which helps when tracking down problems. They may be suitable to remove
or change once things seem to be fine enough.
curl has a new --test-event option when built with debug enabled that
then uses curl_easy_perform_ev() instead of curl_easy_perform(). If
built without debug, using --test-event will only output a warning
message.
NOTE: curl_easy_perform_ev() is not part if the public API on purpose.
It is only present in debug builds of libcurl and MUST NOT be considered
stable even then. Use it for libcurl-testing purposes only.
runtests.pl now features an -e command line option that makes it use
--test-event for all curl command line tests. The man page is updated.
libcurl truncates usernames and passwords it reads from .netrc to
LOGINSIZE and PASSWORDSIZE (64) characters without any indication to
the user, to ensure the values returned from Curl_parsenetrc fit in a
caller-provided buffer.
Fix the interface by passing back dynamically allocated buffers
allocated to fit the user's input. The parser still relies on a
256-character buffer to read each line, though.
So now you can include an ~246-character password in your .netrc,
instead of the previous limit of 63 characters.

The new multiply() function detects range value overflows. 32bit
machines will overflow on a 32bit boundary while 64bit hosts support
ranges up to the full 64 bit range.

A rather big overhaul and cleanup.
1 - curl wouldn't properly detect and reject globbing that ended with an
open brace if there were brackets or braces before it. Like "{}{" or
"[0-1]{"
2 - curl wouldn't properly reject empty lists so that "{}{}" would
result in curl getting (nil) strings in the output.
3 - By using strtoul() instead of sscanf() the code will now detected
over and underflows. It now also better parses the step argument to only
accept positive numbers and only step counters that is smaller than the
delta between the maximum and minimum numbers.
4 - By switching to unsigned longs instead of signed ints for the
counters, the max values for []-ranges are now very large (on 64bit
machines).
5 - Bumped the maximum number of globs in a single URL to 100 (from 10)
6 - Simplified the code somewhat and now it stores fixed strings as
single- entry lists. That's also one of the reasons why I did (5) as now
all strings between "globs" will take a slot in the array.
Added test 1234 and 1235 to verify. Updated test 87.

CURLOPT_DNS_USE_GLOBAL_CACHE broke in commit c43127414d (been
broken since the libcurl 7.29.0 release). While this option has been
documented as deprecated for almost a decade and nobody even reported
this bug, it should remain functional.
Added test case 1512 to verify
This is a regression as this logic used to work. It isn't clear when it
broke, but I'm assuming in 7.28.0 when we went all-multi internally.
This likely never worked with the multi interface. As the failed
connection is detected once the multi state has reached DO_MORE, the
Curl_do_more() function was now expanded somewhat so that the
ftp_do_more() function can request to go "back" to the previous state
when it makes another attempt - using PASV.
Added test case 1233 to verify this fix. It has the little issue that it
assumes no service is listening/accepting connections on port 1...

The internal function that's used to detect known file extensions for
the default Content-Type got the the wrong pointer passed in when
CURLFORM_BUFFER + CURLFORM_BUFFERPTR were used. This had the effect that
strlen() would be used which could lead to an out-of-bounds read (and
thus segfault). In most cases it would only lead to it not finding or
using the correct default content-type.
It also showed that test 554 and test 587 were testing for the
previous/wrong behavior and now they're updated as well.

This reverts commit 7ed25cc, reinstating commit 8ec2cb5.
As of 18-jul-2013 we still do have code in libcurl that makes use of these
memory functions. Commit 8ec2cb5 comment still applies and is yet valid.
These memory functions are solely used in Windows builds, so all related
code is protected with '#ifdef WIN32' preprocessor conditional compilation
directives.
Specifically, wcsdup() _wcsdup() are used when building a Windows target with
UNICODE and USE_WINDOWS_SSPI preprocessor symbols defined. This is the case
when building a Windows UNICODE target with Windows native SSL/TLS support
enabled.
Realizing that wcsdup() _wcsdup() are used is a bit tricky given that usage
of these is hidden behind _tcsdup() which is MS way of dealing with code
that must tolerate UNICODE and non-UNICODE compilation. Additionally, MS
header files and those compatible from other compilers use this preprocessor
conditional compilation directive in order to select at compilation time
whether 'wide' or 'ansi' MS API functions are used.
Without this code, Windows build targets with Windows native SSL/TLS support
enabled and MemoryTracking support enabled misbehave in tracking memory usage,
regardless of being a UNICODE enabled build or not.
Fixed issue with static build for MSVC2010.
After some investigation I've discovered known issue
http://public.kitware.com/Bug/view.php?id=11240 When .rc file is linked

Fix add target property /MACHINE: for MSVC generation.
Also removed old workarounds - it caused errors during msvc build.
Bug: http://curl.haxx.se/mail/lib-2013-07/0046.html
When doing multi-part formposts, libcurl used a pseudo-random value that
was seeded with time(). This turns out to be bad for users who formpost
data that is provided with users who then can guess how the boundary
string will look like and then they can forge a different formpost part
and trick the receiver.
My advice to such implementors is (still even after this change) to not
rely on the boundary strings being cryptographically strong. Fix your
code and logic to not depend on them that much!
I moved the Curl_rand() function into the sslgen.c source file now to be
able to take advantage of the SSL library's random function if it
provides one. If not, try to use the RANDOM_FILE for seeding and as a
last resort keep the old logic, just modified to also add microseconds
which makes it harder to properly guess the exact seed.
The formboundary() function in formdata.c is now using 64 bit entropy
for the boundary and therefore the string of dashes was reduced by 4
letters and there are 16 hex digits following it. The total length is
thus still the same.
