"git fetch http::/site/path" did not die correctly and segfaulted
instead.
* jk/fix-remote-curl-url-wo-proto:
remote-curl: handle URLs without protocol
|
|
Generally remote-curl would never see a URL that did not
have "proto:" at the beginning, as that is what tells git to
run the "git-remote-proto" helper (and git-remote-http, etc,
are aliases for git-remote-curl).
However, the special syntax "proto::something" will run
git-remote-proto with only "something" as the URL. So a
malformed URL like:
http::/example.com/repo.git
will feed the URL "/example.com/repo.git" to
git-remote-http. The resulting URL has no protocol, but the
code added by 372370f (http: use credential API to handle
proxy authentication, 2016-01-26) does not handle this case
and segfaults.
For the purposes of this code, we don't really care what the
exact protocol; only whether or not it is https. So let's
just assume that a missing protocol is not, and curl will
handle the real error (which is that the URL is nonsense).

Before 14111fc (git: submodule honor -c credential.* from
command line, 2016-02-29), it was sufficient for code which
spawned a process in a submodule to just set the child
process's "env" field to "local_repo_env" to clear the
environment of any repo-specific variables.
That commit introduced a more complicated procedure, in
which we clear most variables but allow through sanitized
config. For C code, we used that procedure only for cloning,
but not for any of the programs spawned by submodule.c. As a
result, things like "git fetch --recurse-submodules" behave
differently than "git clone --recursive"; the former will
not pass through the sanitized config.
We can fix this by using prepare_submodule_repo_env()
everywhere in submodule.c.

Commit 14111fc (git: submodule honor -c credential.* from
command line, 2016-02-29) taught git-submodule.sh to save
the sanitized value of $GIT_CONFIG_PARAMETERS when clearing
the environment for a submodule. However, it failed to
export the result, meaning that it had no effect for any
sub-programs.
We didn't catch this in our initial tests because we checked
only the "clone" case, which does not go through the shell
script at all. Provoking "git submodule update" to do a
fetch demonstrates the bug.

Right now we test only the cloning case, but there are other
interesting cases (e.g., fetching). Let's pull the setup
bits into their own test, which will make things flow more
logically once we start adding more tests which use the
setup.
Let's also introduce some whitespace to the clone-test to
split the two parts: making sure it fails without our
cmdline config, and that it succeeds with it.

Commit 14111fc (git: submodule honor -c credential.* from
command line, 2016-02-29) accidentally wrote $HTTP_URL. It
happened to work because we ended up with "credential..helper",
which we treat the same as "credential.helper", applying it
to all URLs.

Due to the way that the git-submodule code works, it clears all local
git environment variables before entering submodules. This is normally
a good thing since we want to clear settings such as GIT_WORKTREE and
other variables which would affect the operation of submodule commands.
However, GIT_CONFIG_PARAMETERS is special, and we actually do want to
preserve these settings. However, we do not want to preserve all
configuration as many things should be left specific to the parent
project.
Add a git submodule--helper function, sanitize-config, which shall be
used to sanitize GIT_CONFIG_PARAMETERS, removing all key/value pairs
except a small subset that are known to be safe and necessary.
Replace all the calls to clear_local_git_env with a wrapped function
that filters GIT_CONFIG_PARAMETERS using the new helper and then
restores it to the filtered subset after clearing the rest of the
environment.

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.

Test clean-up.
* jk/skip-http-tests-under-no-curl:
tests: skip dav http-push tests under NO_EXPAT=NoThanks
t/lib-httpd.sh: skip tests if NO_CURL is defined
|
|
If we built git without curl, we can't actually test against
an http server. In fact, all of the test scripts which
include lib-httpd.sh already perform this check, with one
exception: t5540. For those scripts, this is a noop, and for
t5540, this is a bugfix (it used to fail when built with
NO_CURL, though it could go unnoticed if you had a stale
git-remote-https in your build directory).

Some tests run diff or grep to produce an output, and then
compare the output to an expected value. We know the exit
code we expect these processes to have (e.g., grep yields 0
if it produced output and 1 otherwise), so it would not make
the test wrong to look for it. But the difference between
their output and the expected output (e.g., shown by
test_cmp) is much more useful to somebody debugging the test
than the test just bailing out.
These tests break the &&-chain to skip the exit-code check
of the process. However, we can get the same effect by using
test_might_fail. Note that in some cases the test did use
"|| return 1", which meant the test was not wrong, but it
did fool --chain-lint.

These are tests which are missing a link in their &&-chain,
but during a setup phase. We may fail to notice failure in
commands that build the test environment, but these are
typically not expected to fail at all (but it's still good
to double-check that our test environment is what we
expect).

Using environment variable LANGUAGE and friends on the client side,
HTTP-based transports now send Accept-Language when making requests.
* ye/http-accept-language:
http: add Accept-Language header if possible
|
|
A broken pack .idx file in the receiving repository prevented the
dumb http transport from fetching a good copy of it from the other
side.
* jk/dumb-http-idx-fetch-fix:
dumb-http: do not pass NULL path to parse_pack_index
|
|
Add an Accept-Language header which indicates the user's preferred
languages defined by $LANGUAGE, $LC_ALL, $LC_MESSAGES and $LANG.
Examples:
LANGUAGE= -> ""
LANGUAGE=ko:en -> "Accept-Language: ko, en;q=0.9, *;q=0.1"
LANGUAGE=ko LANG=en_US.UTF-8 -> "Accept-Language: ko, *;q=0.1"
LANGUAGE= LANG=en_US.UTF-8 -> "Accept-Language: en-US, *;q=0.1"
This gives git servers a chance to display remote error messages in
the user's preferred language.
Limit the number of languages to 1,000 because q-value must not be
smaller than 0.001, and limit the length of Accept-Language header to
4,000 bytes for some HTTP servers which cannot accept such long header.

Once upon a time, dumb http always fetched .idx files
directly into their final location, and then checked their
validity with parse_pack_index. This was refactored in
commit 750ef42 (http-fetch: Use temporary files for
pack-*.idx until verified, 2010-04-19), which uses the
following logic:
1. If we have the idx already in place, see if it's
valid (using parse_pack_index). If so, use it.
2. Otherwise, fetch the .idx to a tempfile, check
that, and if so move it into place.
3. Either way, fetch the pack itself if necessary.
However, it got step 1 wrong. We pass a NULL path parameter
to parse_pack_index, so an existing .idx file always looks
broken. Worse, we do not treat this broken .idx as an
opportunity to re-fetch, but instead return an error,
ignoring the pack entirely. This can lead to a dumb-http
fetch failing to retrieve the necessary objects.
This doesn't come up much in practice, because it must be a
packfile that we found out about (and whose .idx we stored)
during an earlier dumb-http fetch, but whose packfile we
_didn't_ fetch. I.e., we did a partial clone of a
repository, didn't need some packfiles, and now a followup
fetch needs them.

extract_content_type() could not extract a charset parameter if the
parameter is not the first one and there is a whitespace and a following
semicolon just before the parameter. For example:
text/plain; format=fixed ;charset=utf-8
And it also could not handle correctly some other cases, such as:
text/plain; charset=utf-8; format=fixed
text/plain; some-param="a long value with ;semicolons;"; charset=utf-8

We currently recognize an error message with a content-type
"text/plain; charset=utf-16" as text, but we ignore the
charset parameter entirely. Let's encode it to
log_output_encoding, which is presumably something the
user's terminal can handle.

When we get a content-type from curl, we get the whole
header line, including any parameters, and without any
normalization (like downcasing or whitespace) applied.
If we later try to match it with strcmp() or even
strcasecmp(), we may get false negatives.
This could cause two visible behaviors:
1. We might fail to recognize a smart-http server by its
content-type.
2. We might fail to relay text/plain error messages to
users (especially if they contain a charset parameter).
This patch teaches the http code to extract and normalize
just the type/subtype portion of the string. This is
technically passing out less information to the callers, who
can no longer see the parameters. But none of the current
callers cares, and a future patch will add back an
easier-to-use method for accessing those parameters.
