Julian Phillips	e8c8b7139c	string_list: Fix argument order for string_list_lookup Update the definition and callers of string_list_lookup to use the string_list as the first argument. This helps make the string_list API easier to use by being more consistent. Signed-off-by: Julian Phillips <julian@quantumfyre.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago

Jeff King	638794cde0	make url-related functions reusable The is_url function and url percent-decoding functions were static, but are generally useful. Let's make them available to other parts of the code. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago
Shawn O. Pearce	5856b5f568	http-backend: Don't infinite loop during die() If stdout has already been closed by the CGI and die() gets called, the CGI will fail to write the "Status: 500 Internal Server Error" to the pipe, which results in die() being called again (via safe_write). This goes on in an infinite loop until the stack overflows and the process is killed by SIGSEGV. Instead set a flag on the first die() invocation and if we came back to the handler, just die silently, as it only means we failed to report the failure---we cannot report anything anyway in such a case. This way failures to write the error messages to the stdout pipe do not result in an infinite loop. We also now report on the death to stderr before we report to stdout, to increase the chances that the cause of the die() invocation will appear in the server's error log. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com> fixup! http-backend.c: Don't infinite loop Now die_webcgi() actually can return during a recursive call into it, causing http-backend.c:554: error: 'noreturn' function does return The only reason we would come back to the die handler is because we failed during it, so we cannot report anything anyway.

Johannes Sixt	ebaa79f462	Make report() from usage.c public as vreportf() and use it. There exist already a number of static functions named 'report', therefore, the function name was changed. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago
Tarmigan Casebolt	8b2bd7cdac	Smart-http: check if repository is OK to export before serving it Similar to how git-daemon checks whether a repository is OK to be exported, smart-http should also check. This check can be satisfied in two different ways: the environmental variable GIT_HTTP_EXPORT_ALL may be set to export all repositories, or the individual repository may have the file git-daemon-export-ok.

Tarmigan Casebolt	354870171b	http-backend: Let gcc check the format of more printf-type functions. We already have these checks in many printf-type functions that have prototypes which are in header files.

Shawn O. Pearce	4a5328d644	http-backend: Fix bad treatment of uintmax_t in Content-Length Our Content-Length needs to report an off_t, which could be larger precision than size_t on this system (e.g. 32 bit binary built with 64 bit large file support). We also shouldn't be passing a size_t parameter to printf when we've used PRIuMAX as the format specifier. Fix both issues by using uintmax_t for the hdr_int() routine, allowing strbuf's size_t to automatically upcast, and off_t to always fit. Also fixed the copy loop we use inside of send_local_file(), we never actually updated the size variable so we might as well not use it.

Shawn O. Pearce	34b6cb8bb0	http-backend: Protect GIT_PROJECT_ROOT from /../ requests Eons ago HPA taught git-daemon how to protect itself from /../ attacks, which Junio brought back into service in `d79374c7b5` ("daemon.c and path.enter_repo(): revamp path validation"). I did not carry this into git-http-backend as originally we relied only upon PATH_TRANSLATED, and assumed the HTTP server had done its access control checks to validate the resolved path was within a directory permitting access from the remote client. This would usually be sufficient to protect a server from requests for its /etc/passwd file by http://host/smart/../etc/passwd sorts of URLs. However in `917adc0360` Mark Lodato added GIT_PROJECT_ROOT as an additional method of configuring the CGI. When this environment variable is used the web server does not generate the final access path and therefore may blindly pass through "/../etc/passwd" in PATH_INFO under the assumption that "/../" might have special meaning to the invoked CGI. Instead of permitting these sorts of malformed path requests, we now reject them back at the client, with an error message for the server log. This matches git-daemon behavior.

Shawn O. Pearce	5abb013b3d	http-backend: Use http.getanyfile to disable dumb HTTP serving Some repository owners may wish to enable smart HTTP, but disallow dumb content serving. Disallowing dumb serving might be because the owners want to rely upon reachability to control which objects clients may access from the repository, or they just want to encourage clients to use the more bandwidth efficient transport. If http.getanyfile is set to false the backend CGI will return with '403 Forbidden' when an object file is accessed by a dumb client. Signed-off-by: Shawn O.

Mark Lodato	917adc0360	http-backend: add GIT_PROJECT_ROOT environment var Add a new environment variable, GIT_PROJECT_ROOT, to override the method of using PATH_TRANSLATED to find the git repository on disk. This makes it much easier to configure the web server, especially when the web server's DocumentRoot does not contain the git repositories, which is the usual case.

Shawn O. Pearce	556cfa3b6d	Smart fetch and push over HTTP: server side Requests for $GIT_URL/git-receive-pack and $GIT_URL/git-upload-pack are forwarded to the corresponding backend process by directly executing it and leaving stdin and stdout connected to the invoking web server. Prior to starting the backend process the HTTP response headers are sent, thereby freeing the backend from needing to know about the HTTP protocol. Requests that are encoded with Content-Encoding: gzip are automatically inflated before being streamed into the backend. This is primarily useful for the git-upload-pack backend, which receives highly repetitive text data from clients that easily compresses to 50% of its original size. Signed-off-by: Shawn O.

Shawn O. Pearce	2f4038ab33	Git-aware CGI to provide dumb HTTP transport The git-http-backend CGI can be configured into any Apache server using ScriptAlias, such as with the following configuration: LoadModule cgi_module /usr/libexec/apache2/mod_cgi.so LoadModule alias_module /usr/libexec/apache2/mod_alias.so ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/ Repositories are accessed via the translated PATH_INFO. The CGI is backwards compatible with the dumb client, allowing all older HTTP clients to continue to download repositories which are managed by the CGI. Signed-off-by: Shawn O.
