2018-02-28t5570-git-daemon: don't check the stderr of a subshellSZEDER Gábor
The test 'no-op fetch without "-v" is quiet' in 't5570-git-daemon.sh' fails when the test script is run with '-x' tracing (and using a shell other than a Bash version supporting BASH_XTRACEFD). The reason for the failure is that the test checks the emptiness of a subshell's stderr, which includes the trace of commands executed in that subshell as well, throwing off the emptiness check. Save the stderr of 'git fetch' only instead of the whole subshell's, so it remains free from tracing output. After this change t5570 passes with '-x', even when running with /bin/sh.

2018-01-25daemon: fix length computation in newline strippingJeff King
When git-daemon gets a pktline request, we strip off any trailing newline, replacing it with a NUL. Clients prior to 5ad312bede (in git v1.4.0) would send: git-upload-pack repo.git\n and we need to strip it off to understand their request. After 5ad312bede, we send the host attribute but no newline, like: git-upload-pack repo.git\0host=example.com\0 Both of these are parsed correctly by git-daemon. But if some client were to combine the two: git-upload-pack repo.git\n\0host=example.com\0 we don't parse it correctly. The problem is that we use the "len" variable to record the position of the NUL separator, but then decrement it when we strip the newline. So we start with: git-upload-pack repo.git\n\0host=example.com\0 ^-- len and end up with: git-upload-pack repo.git\0\0host=example.com\0 ^-- len This is arguably correct, since "len" tells us the length of the initial string, but we don't actually use it for that. What we do use it for is finding the offset of the extended attributes; they used to be at len+1, but are now at len+2. We can solve that by just leaving "len" where it is. We don't have to care about the length of the shortened string, since we just treat it like a C string. No version of Git ever produced such a string, but it seems like the daemon code meant to handle this case (and it seems like a reasonable thing for somebody to do in a 3rd-party implementation).

2018-01-25daemon: handle NULs in extended attribute stringJeff King
If we receive a request with extended attributes after the NUL, we try to write those attributes to the log. We do so with a "%s" format specifier, which will only show characters up to the first NUL. That's enough for printing a "host=" specifier. But since dfe422d04d (daemon: recognize hidden request arguments, 2017-10-16) we may have another NUL, followed by protocol parameters, and those are not logged at all. Let's cut out the attempt to show the whole string, and instead log when we parse individual attributes. We could leave the "extended attributes (%d bytes) exist" part of the log, which in theory could alert us to attributes that fail to parse. But anything we don't parse as a "host=" parameter gets blindly added to the "protocol" attribute, so we'd see it in that part of the log.

2018-01-25daemon: fix off-by-one in logging extended attributesJeff King
If receive a request like: git-upload-pack /foo.git\0host=localhost we mark the offset of the NUL byte as "len", and then log the bytes after the NUL with a "%.*s" placeholder, using "pktlen - len" as the length, and "line + len + 1" as the start of the string. This is off-by-one, since the start of the string skips past the separating NUL byte, but the adjusted length includes it. Fortunately this doesn't actually read past the end of the buffer, since "%.*s" will stop when it hits a NUL. And regardless of what is in the buffer, packet_read() will always add an extra NUL terminator for safety. As an aside, the git.git client sends an extra NUL after a "host" field, too, so we'd generally hit that one first, not the one added by packet_read(). You can see this in the test output which reports 15 bytes, even though the string has only 14 bytes of visible data. But the point is that even a client sending unusual data could not get us to read past the end of the buffer, so this is purely a cosmetic fix.

2018-01-25t5570: use ls-remote instead of clone for interp testsJeff King
We don't actually care about the clone operation here; we just want to know if we were able to actually contact the remote repository. Using ls-remote does that more efficiently, and without us having to worry about managing the tmp.git directory.

2016-01-04t/t5570-git-daemon.sh: use the $( ... ) construct for command substitutionElia Pinto
The Git CodingGuidelines prefer the $(...) construct for command substitution instead of using the backquotes `...`. The backquoted form is the traditional method for command substitution, and is supported by POSIX. However, all but the simplest uses become complicated quickly. In particular, embedded command substitutions and/or the use of double quotes require careful escaping with the backslash character. The patch was generated by: for _f in $(find . -name "*.sh") do perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg' "${_f}" done and then carefully proof-read.

2015-02-17daemon: sanitize incoming virtual hostnameJeff King
We use the daemon_avoid_alias function to make sure that the pathname the user gives us is sane. However, after applying that check, we might then interpolate the path using a string given by the server admin, but which may contain more untrusted data from the client. We should be sure to sanitize this data, as well. We cannot use daemon_avoid_alias here, as it is more strict than we need in requiring a leading '/'. At the same time, we can be much more strict here. We are interpreting a hostname, which should not contain slashes or excessive runs of dots, as those things are not allowed in DNS names. Note that in addition to cleansing the hostname field, we must check the "canonical hostname" (%CH) as well as the port (%P), which we take as a raw string. For the canonical hostname, this comes from an actual DNS lookup on the accessed IP, which makes it a much less likely vector for problems. But it does not hurt to sanitize it in the same way. Unfortunately we cannot test this case easily, as it would involve a custom hostname lookup. We do not need to check %IP, as it comes straight from inet_ntop, so must have a sane form.

git clone now reports its progress to standard error, which throws off t5570. Using test_i18ngrep instead of test_cmp allows the test to be more flexible by only looking for the expected error and ignoring any other output from the program.

2012-04-24t5570: use explicit push refspecClemens Buchacher
The default mode for push without arguments will change. Some warnings are about to be enabled for such use, which causes some t5570 tests to fail because they do not expect this output. Fix this by passing an explicit refspec to git push. To that end, change the calling conventions of test_remote_error in order to accomodate extra command arguments.

The semantics of the git daemon tests are similar to the http transport tests. In fact, they are only a slightly modified copy of t5550, plus the newly added remote error tests. All git-daemon tests will be skipped unless the environment variable GIT_TEST_GIT_DAEMON is set.
