For pop3/imap/smtp, added test 891 to somewhat verify the pop3
case.
For this, I enhanced the pingpong test server to be able to send back
responses with LF-only instead of always using CRLF.
Closes#2150
... as the test cases themselves do that and it makes it easier to add
crazy test cases.
Test 800 updated to use user name + password that need quoting.
Test 856 updated to trigger an auth fail differently.
Ref: #1902
We're mostly saying just "curl" in lower case these days so here's a big
cleanup to adapt to this reality. A few instances are left as the
project could still formally be considered called cURL.
According to section 2.2 of RFC959 the End-of-Line is defined as:
The end-of-line sequence defines the separation of printing
lines. The sequence is Carriage Return, followed by Line Feed.
Verified by sniffing traffic between a Windows FTP client (FileZilla)
and Unix-hosted FTP server (ProFTPD).
Also, make the ftp server return a canned response that doesn't
cause XML verification problems. Although the test file format
isn't technically XML, it's still handy to be able to use XML
tools to verify and manipulate them.
Previously LIST always returned a fixed hardcoded list that the ftp
server code knew about, mostly since the server didn't get any test case
number in the LIST scenario. Starting now, doing a CWD to a directory
named test-[number] will make the test server remember that number and
consider it a test case so that a subsequent LIST command will send the
<data> section of that test case back.
It allows LIST tests to be made more similar to how all other tests
work.
Test 100 was updated to provide its own directory listing.
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.
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.
...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 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.
