Ævar Arnfjörð Bjarmason 7596fe952d tests: add LIBCURL prerequisite to tests needing libcurl
Add and use a LIBCURL prerequisite for tests added in
6dcbdc0d66 (remote: create fetch.credentialsInUrl config,
2022-06-06).

These tests would get as far as emitting a couple of the warnings we
were testing for, but would then die as we had no "git-remote-https"
program compiled.

It would be more consistent with other prerequisites (e.g. PERL for
NO_PERL) to name this "CURL", but since e9184b0789 (t5561: skip tests
if curl is not available, 2018-04-03) we've had that prerequisite
defined for checking of we have the curl(1) program.

The existing "CURL" prerequisite is only used in one place, and we
should probably name it "CURL_PROGRAM", then rename "LIBCURL" to
"CURL" as a follow-up, but for now (pre-v2.37.0) let's aim for the
most minimal fix possible.

Jeff King e4c9538a9c send-pack: complain about "expecting report" with --helper-status
When pushing to a server which erroneously omits the final ref-status
report, the client side should complain about the refs for which we
didn't receive the status (because we can't just assume they were
updated). This works over most transports like ssh, but for http we'll
print a very misleading "Everything up-to-date".

It works for ssh because send-pack internally sets the status of each
ref to REF_STATUS_EXPECTING_REPORT, and then if the server doesn't tell
us about a particular ref, it will stay at that value. When we print the
final status table, we'll see that we're still on EXPECTING_REPORT and
complain then.

But for http, we go through remote-curl, which invokes send-pack with
"--stateless-rpc --helper-status". The latter option causes send-pack to
return a machine-readable list of ref statuses to the remote helper. But
ever since its inception in de1a2fdd38 (Smart push over HTTP: client
side, 2009-10-30), the send-pack code has simply omitted mention of any
ref which ended up in EXPECTING_REPORT.

In the remote helper, we then take the absence of any status report
from send-pack to mean that the ref was not even something we tried to
send, and thus it prints "Everything up-to-date". Fortunately it does
detect the eventual non-zero exit from send-pack, and propagates that in
its own non-zero exit code. So at least a careful script invoking "git
push" would notice the failure.  But sending the misleading message on
stderr is certainly confusing for humans (not to mention the
machine-readable "push --porcelain" output, though again, any careful
script should be checking the exit code from push, too).

Nobody seems to have noticed because the server in this instance has to
be misbehaving: it has promised to support the ref-status capability
(otherwise the client will not set EXPECTING_REPORT at all), but didn't
send us any. If the connection were simply cut, then send-pack would
complain about getting EOF while trying to read the status. But if the
server actually sends a flush packet (i.e., saying "now you have all of
the ref statuses" without actually sending any), then the client ends up
in this confused situation.

The fix is simple: we should return an error message from "send-pack
--helper-status", just like we would for any other error per-ref error
condition (in the test I included, the server simply omits all ref
status responses, but a more insidious version of this would skip only
some of them).

Denton Liu 74b082ad34 remote-curl: error on incomplete packet
Currently, remote-curl acts as a proxy and blindly forwards packets
between an HTTP server and fetch-pack. In the case of a stateless RPC
connection where the connection is terminated with a partially written
packet, remote-curl will blindly send the partially written packet
before waiting on more input from fetch-pack. Meanwhile, fetch-pack will
read the partial packet and continue reading, expecting more input. This
results in a deadlock between the two processes.

For a stateless connection, inspect packets before sending them and
error out if a packet line packet is incomplete.

Johannes Schindelin eafff6e41e t/lib-httpd: avoid using macOS' sed
Among other differences relative to GNU sed, macOS' sed always ends its
output with a trailing newline, even if the input did not have such a
trailing newline.

Surprisingly, this makes three httpd-based tests fail on macOS: t5616,
t5702 and t5703. ("Surprisingly" because those tests have been around
for some time, but apparently nobody runs them on macOS with a working
Apache2 setup.)

The reason is that we use `sed` in those tests to filter the response of
the web server. Apart from the fact that we use GNU constructs (such as
using a space after the `c` command instead of a backslash and a
newline), we have another problem: macOS' sed LF-only newlines while
webservers are supposed to use CR/LF ones.

Even worse, t5616 uses `sed` to replace a binary part of the response
with a new binary part (kind of hoping that the replaced binary part
does not contain a 0x0a byte which would be interpreted as a newline).

To that end, it calls on Perl to read the binary pack file and
hex-encode it, then calls on `sed` to prefix every hex digit pair with a
`\x` in order to construct the text that the `c` statement of the `sed`
invocation is supposed to insert. So we call Perl and sed to construct a
sed statement. The final nail in the coffin is that macOS' sed does not
even interpret those `\x<hex>` constructs.

Let's just replace all of that by Perl snippets. With Perl, at least, we
do not have to deal with GNU vs macOS semantics, we do not have to worry
about unwanted trailing newlines, and we do not have to spawn commands
to construct arguments for other commands to be spawned (i.e. we can
avoid a whole lot of shell scripting complexity).

The upshot is that this fixes t5616, t5702 and t5703 on macOS with
Apache2.

SZEDER Gábor 43a2afee82 tests: add 'test_bool_env' to catch non-bool GIT_TEST_* values
Since 3b072c577b (tests: replace test_tristate with "git env--helper",
2019-06-21) we get the normalized bool values of various GIT_TEST_*
environment variables via 'git env--helper'.  Now, while the 'git
env--helper' command itself does catch invalid values in the
environment variable or in the given --default and exits with error
(exit code 128 or 129, respectively), it's invoked in conditions like
'if ! git env--helper ...', which means that all invalid bool values
are interpreted the same as the ordinary 'false' (exit code 1).  This
has led to inadvertently skipped httpd tests in our CI builds for a
couple of weeks, see 3960290675 (ci: restore running httpd tests,
2019-09-06).

Let's be more careful about what the test suite accepts as bool values
in GIT_TEST_* environment variables, and error out loud and clear on
invalid values instead of simply skipping tests.  Add the
'test_bool_env' helper function to encapsulate the invocation of 'git
env--helper' and the verification of its exit code, and replace all
invocations of that command in our test framework and test suite with
a call to this new helper (except in 't0017-env-helper.sh', of
course).

  $ GIT_TEST_GIT_DAEMON=YesPlease ./t5570-git-daemon.sh
  fatal: bad numeric config value 'YesPlease' for 'GIT_TEST_GIT_DAEMON': invalid unit
  error: test_bool_env requires bool values both for $GIT_TEST_GIT_DAEMON and for the default fallback

Ævar Arnfjörð Bjarmason 3b072c577b tests: replace test_tristate with "git env--helper"
The test_tristate helper introduced in 83d842dc8c ("tests: turn on
network daemon tests by default", 2014-02-10) can now be better
implemented with "git env--helper" to give the variables in question
the standard boolean behavior.

The reason for the "tristate" was to have all of false/true/auto,
where "auto" meant either "false" or "true" depending on what the
fallback was. With the --default option to "git env--helper" we can
simply have e.g. GIT_TEST_HTTPD where we know if it's true because the
user asked explicitly ("true"), or true implicitly ("auto").

This breaks backwards compatibility for explicitly setting "auto" for
these variables, but I don't think anyone cares. That was always
intended to be internal.

This means the test_normalize_bool() code in test-lib-functions.sh
goes away in addition to test_tristate(). We still need the
test_skip_or_die() helper, but now it takes the variable name instead
of the value, and uses "git env--bool" to distinguish a default "true"
from an explicit "true" (in those "explicit true" cases we want to
fail the test in question).

SZEDER Gábor fa84058180 test-lib-functions: introduce the 'test_set_port' helper function
Several test scripts run daemons like 'git-daemon' or Apache, and
communicate with them through TCP sockets.  To have unique ports where
these daemons are accessible, the ports are usually the number of the
corresponding test scripts, unless the user overrides them via
environment variables, and thus all those tests and test libs contain
more or less the same bit of one-liner boilerplate code to find out
the port.  The last patch in this series will make this a bit more
complicated.

Factor out finding the port for a daemon into the common helper
function 'test_set_port' to avoid repeating ourselves.

Take special care of test scripts with "low" numbers:

  - Test numbers below 1024 would result in a port that's only usable
    as root, so set their port to '10000 + test-nr' to make sure it
    doesn't interfere with other tests in the test suite.  This makes
    the hardcoded port number in 't0410-partial-clone.sh' unnecessary,
    remove it.

  - The shell's arithmetic evaluation interprets numbers with leading
    zeros as octal values, which means that test number below 1000 and
    containing the digits 8 or 9 will trigger an error.  Remove all
    leading zeros from the test numbers to prevent this.

Note that the 'git p4' tests are unlike the other tests involving
daemons in that:

  - 'lib-git-p4.sh' doesn't use the test's number for unique port as
    is, but does a bit of additional arithmetic on top [1].

  - The port is not overridable via an environment variable.

With this patch even 'git p4' tests will use the test's number as
default port, and it will be overridable via the P4DPORT environment
variable.

[1] Commit fc00233071 (git-p4 tests: refactor and cleanup, 2011-08-22)
    introduced that "unusual" unique port computation without
    explaining why it was necessary (as opposed to simply using the
    test number as is).  It seems to be just unnecessary complication,
    and in any case that commit came way before the "test nr as unique
    port" got "standardized" for other daemons in commits c44132fcf3
    (tests: auto-set git-daemon port, 2014-02-10), 3bb486e439 (tests:
    auto-set LIB_HTTPD_PORT from test name, 2014-02-10), and

Junio C Hamano bc6d33e87a Merge branch 'sg/httpd-test-unflake'

  t/lib-httpd: avoid occasional failures when checking access.log
  t/lib-httpd: add the strip_access_log() helper function
  t5541: clean up truncating access log
2018-08-02 15:30:39 -07:00
SZEDER Gábor e8b3b2e275 t/lib-httpd: avoid occasional failures when checking access.log
The last test of 't5561-http-backend.sh', 'server request log matches
test results' may fail occasionally, because the order of entries in
Apache's access log doesn't match the order of requests sent in the
previous tests, although all the right requests are there.  I saw it
fail on Travis CI five times in the span of about half a year, when
the order of two subsequent requests was flipped, and could trigger
the failure with a modified Git.  However, I was unable to trigger it
with stock Git on my machine.  Three tests in
't5541-http-push-smart.sh' and 't5551-http-fetch-smart.sh' check
requests in the log the same way, so they might be prone to a similar
occasional failure as well.

When a test sends a HTTP request, it can continue execution after
'git-http-backend' fulfilled that request, but Apache writes the
corresponding access log entry only after 'git-http-backend' exited.
Some time inevitably passes between fulfilling the request and writing
the log entry, and, under unfavourable circumstances, enough time
might pass for the subsequent request to be sent and fulfilled by a
different Apache thread or process, and then Apache writes access log
entries racily.

This effect can be exacerbated by adding a bit of variable delay after
the request is fulfilled but before 'git-http-backend' exits, e.g.
like this:

  diff --git a/http-backend.c b/http-backend.c
  index f3dc218b2..bbf4c125b 100644
  --- a/http-backend.c
  +++ b/http-backend.c
  @@ -709,5 +709,7 @@ int cmd_main(int argc, const char **argv)
   					   max_request_buffer);

   	cmd->imp(&hdr, cmd_arg);
  +	if (getpid() % 2)
  +		sleep(1);
   	return 0;
   }

This delay considerably increases the chances of log entries being
written out of order, and in turn makes t5561's last test fail almost
every time.  Alas, it doesn't seem to be enough to trigger a similar
failure in t5541 and t5551.

So, since we can't just rely on the order of access log entries always
corresponding the order of requests, make checking the access log more
deterministic by sorting (simply lexicographically) both the stripped
access log entries and the expected entries before the comparison with
'test_cmp'.  This way the order of log entries won't matter and
occasional out-of-order entries won't trigger a test failure, but the
comparison will still notice any unexpected or missing log entries.

OTOH, this sorting will make it harder to identify from which test an
unexpected log entry came from or which test's request went missing.
Therefore, in case of an error include the comparison of the unsorted
log enries in the test output as well.

And since all this should be performed in four tests in three test
scripts, put this into a new helper function 'check_access_log' in
't/lib-httpd.sh'.

Jeff King 1767c51787 t/lib-httpd: switch SANITY check for NOT_ROOT
The SANITY prerequisite is really about whether the
filesystem will respect the permissions we set, and being
root is only one part of that. But the httpd tests really
just care about not being root, as they are trying to avoid
weirdness in apache (see a1a3011 for details).

Let's switch out SANITY for a new NOT_ROOT prerequisite,
which will let us tweak SANITY more freely.

We implement NOT_ROOT by checking `id -u`, which is in POSIX
and seems to be available even on MSYS.  Note that we cannot
just call this "ROOT" and ask for "!ROOT". The possible
outcomes are:

  1. we know we are root

  2. we know we are not root

  3. we could not tell, because `id` was not available

We should conservatively treat (3) as "does not have the
prerequisite", which means that a naive negation would not
work.

Jeff King a1a301114e t/lib-httpd: require SANITY prereq
Our test httpd setup will not generally run as root, because
Apache will want to setuid, and we do not set up the "User"
config directive. On some systems, like current Debian
unstable, Apache fails to start, and we skip the tests:

    $ sudo ./t5539-fetch-http-shallow.sh --debug
    1..0 # SKIP web server setup failed
    $ cat trash*t5539*/httpd/error.log
    [...]
    (22)Invalid argument: AH00024: Couldn't set permissions on
      the rewrite-map mutex; check User and Group directives
    AH00016: Configuration Failed

However, on other systems (reportedly Ubuntu 11.04), Apache
seems to start, and then bails during our tests with:

   getpwuid: couldn't determine user name from uid 4294967295,
     you probably need to modify the User directive
   Child 12037 returned a Fatal error...  Apache is exiting!

This may be related to the pre-fork/threading model in use
(note that the second one complains of the child dying).
However, it's not even worth investigating; in either case
we just want to skip the tests, and we already recommend
against running the test suite as root. Let's just
explicitly check this condition and skip the tests rather
than expecting Apache to do the right thing.

Junio C Hamano ee3a81e69c Merge branch 'jk/run-network-tests-by-default'
Teach "make test" to run networking tests when possible by default.

* jk/run-network-tests-by-default:
  tests: turn on network daemon tests by default
2014-03-05 15:06:45 -08:00
Jeff King 83d842dc8c tests: turn on network daemon tests by default
We do not run the httpd nor git-daemon tests by default, as
they are rather heavyweight and require network access
(albeit over localhost). However, it would be nice if more
pepole ran them, for two reasons:

  1. We would get more test coverage on more systems.

  2. The point of the test suite is to find regressions. It
     is very easy to change some of the underlying code and
     break the httpd code without realizing you are even
     affecting it. Running the httpd tests helps find these
     problems sooner (ideally before the patches even hit
     the list).

We still want to leave an "out", though, for people who really do
not want to run them. For that reason, the GIT_TEST_HTTPD and
GIT_TEST_GIT_DAEMON variables are now tri-state booleans
(true/false/auto), so you can say GIT_TEST_HTTPD=false to turn the
tests back off.  To support those who want a stable single way to
disable these tests across versions of Git before and after this
change, an empty string explicitly set to these variables is also
taken as "false", so the behaviour changes only for those who:

  a. did not express any preference by leaving these variables
     unset.  They did not test these features before, but now they
     do; or

  b. did express that they want to test these features by setting
     GIT_TEST_FEATURE=false (or any equivalent other ways to tell
     "false" to Git, e.g. "0"), which has been a valid but funny way
     to say that they do want to test the feature only because we
     used to interpret any non-empty string to mean "yes please
     test".  They no longer test that feature.

In addition, we are forgiving of common setup failures (e.g., you do
not have apache installed, or have an old version) when the
tri-state is "auto" (or unset), but report an error when it is
"true". This makes "auto" a sane default, as we should not cause
failures on setups where the tests cannot run. But it allows people
who use "true" to catch regressions in their system (e.g., they
uninstalled apache, but were expecting their automated test runs to
test git-httpd, and would want to be notified).

Jeff King 3bb486e439 tests: auto-set LIB_HTTPD_PORT from test name
We set the default apache port for each of the httpd tests
to the 4-digit test number of the test script. We want these
to remain unique so that the tests do not conflict with each
other when run in parallel.

Instead of doing it manually in each test script, let's just
set it from the test name at run time. This is simpler, and
is one less thing to be updated when test scripts are
renamed (e.g., when being re-rolled or when conflicting
after being merged with another topic).

Incidentally, this fixes a case where t5537 and t5538 used
the same port number (5537), and could conflict with each
other when run in parallel.

2014-01-10 10:33:19 -08:00
Jeff King afbf5ca507 use distinct username/password for http auth tests
The httpd server we set up to test git's http client code
knows about a single account, in which both the username and
password are "user@host" (the unusual use of the "@" here is
to verify that we handle the character correctly when URL
escaped).

This means that we may miss a certain class of errors in
which the username and password are mixed up internally by
git. We can make our tests more robust by having distinct
values for the username and password.

In addition to tweaking the server passwd file and the
client URL, we must teach the "askpass" harness to accept
multiple values. As a bonus, this makes the setup of some
tests more obvious; when we are expecting git to ask
only about the password, we can seed the username askpass
response with a bogus value.

Jeff King 050ef3655c remote-curl: rewrite base url from info/refs redirects
For efficiency and security reasons, an earlier commit in
this series taught http_get_* to re-write the base url based
on redirections we saw while making a specific request.

This commit wires that option into the info/refs request,
meaning that a redirect from

    http://example.com/foo.git/info/refs

to

    https://example.com/bar.git/info/refs

will behave as if "https://example.com/bar.git" had been
provided to git in the first place.

The tests bear some explanation. We introduce two new
hierearchies into the httpd test config:

  1. Requests to /smart-redir-limited will work only for the
     initial info/refs request, but not any subsequent
     requests. As a result, we can confirm whether the
     client is re-rooting its requests after the initial
     contact, since otherwise it will fail (it will ask for
     "repo.git/git-upload-pack", which is not redirected).

  2. Requests to smart-redir-auth will redirect, and require
     auth after the redirection. Since we are using the
     redirected base for further requests, we also update
     the credential struct, in order not to mislead the user
     (or credential helpers) about which credential is
     needed. We can therefore check the GIT_ASKPASS prompts
     to make sure we are prompting for the new location.
     Because we have neither multiple servers nor https
     support in our test setup, we can only redirect between
     paths, meaning we need to turn on
     credential.useHttpPath to see the difference.

Jeff King e837936c7c t5550: factor out http auth setup
The t5550 script sets up a nice askpass helper for
simulating user input and checking what git prompted for.
Let's make it available to other http scripts by migrating
it to lib-httpd.

We can use this immediately in t5540 to make our tests more
robust (previously, we did not check at all that hitting the
password-protected repo actually involved a password).
Unfortunately, we end up failing the test because the
current code erroneously prompts twice (once for
git-remote-http, and then again when the former spawns
git-http-push).

More importantly, though, it will let us easily add
smart-http authentication tests in t5541 and t5551; we
currently do not test smart-http authentication at all.

As part of making it generic, let's always look for and
store auxiliary askpass files at the top-level trash
directory; this makes it compatible with t5540, which runs
some tests from sub-repositories. We can abstract away the
ugliness with a short helper function.

Jeff King f628825481 t/lib-httpd: handle running under --valgrind
Running the http tests with valgrind does not work for two
reasons:

  1. Apache complains about following the symbolic link from

  2. Apache does not pass through the GIT_VALGRIND variable
     to the backend CGI.

This patch fixes both problems. Unfortunately, there is a
slight hack we need to handle passing environment variables
through Apache. If we just tell it:

  PassEnv GIT_VALGRIND

then Apache will complain when GIT_VALGRIND is not set. If
we try:

  SetEnv GIT_VALGRIND ${GIT_VALGRIND}

then when GIT_VALGRIND is not set, it will pass through the
literal "${GIT_VALGRIND}". Instead, we now unconditionally
pass through GIT_VALGRIND from lib-httpd.sh into apache,
even if it is empty.
