test smart http fetch and push The top level directory "/smart/" of the test Apache server is mapped through our git-http-backend CGI, but uses the same underlying repository space as the server's document root. This is the most simple installation possible. Server logs are checked to verify the client has accessed only the smart URLs during the test. During fetch testing the headers are also logged from libcurl to ensure we are making a reasonably sane HTTP request, and getting back reasonably sane response headers from the CGI. When validating the request headers used during smart fetch we munge away the actual Content-Length and replace it with the placeholder "xxx". This avoids unnecessary varability in the test caused by an unrelated change in the requested capabilities in the first want line of the request. However, we still want to look for and verify that Content-Length was used, because smaller payloads should be using Content-Length and not "Transfer-Encoding: chunked". When validating the server response headers we must discard both Content-Length and Transfer-Encoding, as Apache2 can use either format to return our response. During development of this test I observed Apache returning both forms, depending on when the processes got CPU time. If our CGI returned the pack data quickly, Apache just buffered the whole thing and returned a Content-Length. If our CGI took just a bit too long to complete, Apache flushed its buffer and instead used "Transfer-Encoding: chunked". Signed-off-by: Shawn O.

t5551-http-fetch: Work around broken Accept header in libcurl Unfortunately at least one version of libcurl has a bug causing it to include "Accept: */*" in the same POST request where we have already asked for "Accept: application/x-git-upload-pack-response". This is a bug in libcurl, not Git, or our test vector. The application has explicitly asked the server for a single content type, but libcurl has mistakenly also told the server the client application will accept */*, which is any content type. Based on the libcurl change log, this "Accept: */*" header bug may have been fixed in version 7.18.1 released March 30, 2008: http://curl.haxx.se/changes.html#7_18_1 Rather than require users to upgrade libcurl we change the test vector to trim this line out of the 2nd request.

smart-http: Don't change POST to GET when following redirect For a long time (29508e1 "Isolate shared HTTP request functionality", Fri Nov 18 11:02:58 2005), we've followed HTTP redirects with CURLOPT_FOLLOWLOCATION. However, when the remote HTTP server returns a redirect the default libcurl action is to change a POST request into a GET request while following the redirect, but the remote http backend does not expect that. Fix this by telling libcurl to always keep the request as type POST with CURLOPT_POSTREDIR. For users of libcurl older than 7.19.1, use CURLOPT_POST301 instead, which only follows 301s instead of both 301s and 302s.

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.

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.

t: test http access to "half-auth" repositories Some sites set up http access to repositories such that fetching is anonymous and unauthenticated, but pushing is authenticated. While there are multiple ways to do this, the technique advertised in the git-http-backend manpage is to block access to locations matching "/git-receive-pack$". Let's emulate that advice in our test setup, which makes it clear that this advice does not actually work. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

remote-curl: retry failed requests for auth even with gzip Commit b81401c taught the post_rpc function to retry the http request after prompting for credentials. However, it did not handle two cases: 1. If we have a large request, we do not retry. That's OK, since we would have sent a probe (with retry) already. 2. If we are gzipping the request, we do not retry. That was considered OK, because the intended use was for push (e.g., listing refs is OK, but actually pushing objects is not), and we never gzip on push. This patch teaches post_rpc to retry even a gzipped request. This has two advantages: 1. It is possible to configure a "half-auth" state for fetching, where the set of refs and their sha1s are advertised, but one cannot actually fetch objects. This is not a recommended configuration, as it leaks some information about what is in the repository (e.g., an attacker can try brute-forcing possible content in your repository and checking whether it matches your branch sha1). However, it can be slightly more convenient, since a no-op fetch will not require a password at all. 2. It future-proofs us should we decide to ever gzip more requests.

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.

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.

remote-curl: let users turn off smart http Usually there is no need for users to specify whether an http remote is smart or dumb; the protocol is designed so that a single initial request is made, and the client can determine the server's capability from the response. However, some misconfigured dumb-only servers may not like the initial request by a smart client, as it contains a query string. Until recently, commit 703e6e7 worked around this by making a second request. However, that commit was recently reverted due to its side effect of masking the initial request's error code. Since git has had that workaround for several years, we don't know exactly how many such misconfigured servers are out there. The reversion of 703e6e7 assumes they are rare enough not to worry about. Still, that reversion leaves somebody who does run into such a server with no escape hatch at all. Let's give them an environment variable they can tweak to perform the "dumb" request. This is intentionally not a documented interface. It's overly simple and is really there for debugging in case somebody does complain about git not working with their server. A real user-facing interface would entail a per-remote or per-URL config variable. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

remote-curl: main test case for the OS command line overflow This is main test case for the original problem that triggered this patch series. We create a repo with 50k tags and then test whether git-clone over the smart HTTP protocol succeeds. Note that we construct the repo in a slightly different way than the original script used to reproduce the problem. This is because the original script just created 50k tags all pointing to the same commit, so if there was a bug where remote-curl.c was not passing all the refs to fetch-pack we wouldn't know. The clone would succeed even if only one tag was passed, because all the other tags were pointing at the same SHA and would be considered present. Instead we create a repo with 50k independent (dangling) commits and then tag each of those commits with a unique tag. This way if one of the tags is not given to fetch-pack, later stages of the clone would complain about it. This allows us to test both that the command line overflow was fixed, as well as that it was fixed in a way that doesn't leave out any of the refs.

tests: Introduce test_seq Jeff King wrote: The seq command is GNU-ism, and is missing at least in older BSD releases and their derivatives, not to mention antique commercial Unixes. We already purged it in b3431bc (Don't use seq in tests, not everyone has it, 2007-05-02), but a few new instances have crept in. They went unnoticed because they are in scripts that are not run by default. Replace them with test_seq that is implemented with a Perl snippet (proposed by Jeff). This is better than inlining this snippet everywhere it's needed because it's easier to read and it's easier to change the implementation (e.g. to C) if we ever decide to remove Perl from the test suite. Note that test_seq is not a complete replacement for seq(1). It just has what we need now, in addition that it makes it possible for us to do something like "test_seq a m" if we wanted to in the future. There are also many places that do `for i in 1 2 3 ...` but I'm not sure if it's worth converting them to test_seq. That would introduce running more processes of Perl.

t: use perl instead of "$PERL_PATH" where applicable As of the last commit, we can use "perl" instead of "$PERL_PATH" when running tests, as the former is now a function which uses the latter. As the shorter "perl" is easier on the eyes, let's switch to using it everywhere. This is not quite a mechanical s/$PERL_PATH/perl/ replacement, though. There are some places where we invoke perl from a script we generate on the fly, and those scripts do not have access to our internal shell functions.

test smart http fetch and push The top level directory "/smart/" of the test Apache server is mapped through our git-http-backend CGI, but uses the same underlying repository space as the server's document root. This is the most simple installation possible. Server logs are checked to verify the client has accessed only the smart URLs during the test. During fetch testing the headers are also logged from libcurl to ensure we are making a reasonably sane HTTP request, and getting back reasonably sane response headers from the CGI. When validating the request headers used during smart fetch we munge away the actual Content-Length and replace it with the placeholder "xxx". This avoids unnecessary varability in the test caused by an unrelated change in the requested capabilities in the first want line of the request. However, we still want to look for and verify that Content-Length was used, because smaller payloads should be using Content-Length and not "Transfer-Encoding: chunked". When validating the server response headers we must discard both Content-Length and Transfer-Encoding, as Apache2 can use either format to return our response. During development of this test I observed Apache returning both forms, depending on when the processes got CPU time. If our CGI returned the pack data quickly, Apache just buffered the whole thing and returned a Content-Length. If our CGI took just a bit too long to complete, Apache flushed its buffer and instead used "Transfer-Encoding: chunked". Signed-off-by: Shawn O.
