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.

http: use credential API to get passwords This patch converts the http code to use the new credential API, both for http authentication as well as for getting certificate passwords. Most of the code change is simply variable naming (the passwords are now contained inside the credential struct) or deletion of obsolete code (the credential code handles URL parsing and prompting for us). The behavior should be the same, with one exception: the credential code will prompt with a description based on the credential components. Therefore, the old prompt of: Username for 'example.com': Password for 'example.com': now looks like: Username for 'https://example.com/repo.git': Password for 'https://user@example.com/repo.git': Note that we include more information in each line, specifically: 1. We now include the protocol. While more noisy, this is an important part of knowing what you are accessing (especially if you care about http vs https). 2. We include the username in the password prompt. This is not a big deal when you have just been prompted for it, but the username may also come from the remote's URL (and after future patches, from configuration or credential helpers). In that case, it's a nice reminder of the user for which you're giving the password. 3. We include the path component of the URL. In many cases, the user won't care about this and it's simply noise (i.e., they'll use the same credential for a whole site). However, that is part of a larger question, which is whether path components should be part of credential context, both for prompting and for lookup by storage helpers. That issue will be addressed as a whole in a future patch. Similarly, for unlocking certificates, we used to say: Certificate Password for 'example.com': and we now say: Password for 'cert:///path/to/certificate': Showing the path to the client certificate makes more sense, as that is what you are unlocking, not "example.com".
