t5516: move plaintext-password tests from t5601 and t5516
Commit 6dcbdc0d66
(remote: create fetch.credentialsInUrl config,
2022-06-06) added tests for our handling of passwords in URLs. Since the
obvious URL to be affected is git-over-http, the tests use http. However
they don't set up a test server; they just try to access
https://localhost, assuming it will fail (because the nothing is
listening there).
This causes some possible problems:
- There might be a web server running on localhost, and we do not
actually want to connect to that.
- The DNS resolver, or the local firewall, might take a substantial
amount of time (or forever, whichever comes first) to fail to
connect, slowing down the tests cases unnecessarily.
- Since there's no server, our tests for "allow" and "warn" still
expect the clone/fetch/push operations to fail, even though in the
real world we'd expect these to succeed. We scrape stderr to see
what happened, but it's not as robust as a more realistic test.
Let's instead move these to t5551, which is all about testing http and
where we have a real server. That eliminates any issues with contacting
a strange URL, and lets the "allow" and "warn" tests confirm that the
operation actually succeeds.
It's not quite a verbatim move for a few reasons:
- we can drop the LIBCURL dependency; it's already part of
lib-httpd.sh
- we'll use HTTPD_URL_USER_PASS, etc, instead of our fake URL. To
avoid repetition, we'll add a few extra variables.
- the "https://username:@localhost" test uses a funny URL that
lib-httpd.sh doesn't provide. We'll similarly construct it in a
variable. Note that we're hard-coding the lib-httpd username here,
but t5551 already does that everywhere.
- for the "domain:port" test, the URL provided by lib-httpd is fine,
since our test server will always be on an exotic port. But we'll
confirm in the test that this is so.
- since our message-matching is done via grep, I simplified it to use
a regex, rather than trying to massage lib-httpd's variables.
Arguably this makes it more readable, too, while retaining the bits
we care about: the fatal/warning distinction, the "uses plaintext"
message, and the fact that the password was redacted.
- we'll use the /auth/ path for the repo, which shows that we are
indeed making use of the auth information when needed.
- we'll also use /smart/; most of these tests could be done via /dumb/
in t5550, but setting up pushes there requires extra effort and
dependencies. The smart protocol is what most everyone is using
these days anyway.
This patch is my own, but I stole the analysis and a few bits of the
commit message from a patch by Johannes Schindelin.
