http.c: Don't store destination name in request structures

2010-04-17T20:55:46Z

The destination name within the object store is easily computed on demand, reusing a static buffer held by sha1_file.c. We don't need to copy the entire path into the request structure for safe keeping, when it can be easily reformatted after the download has been completed. This reduces the size of the per-request structure, and removes yet another PATH_MAX based limit. Signed-off-by: Shawn O. Pearce Signed-off-by: Junio C Hamano

Prompt for a username when an HTTP request 401s

2010-04-02T06:24:59Z

When an HTTP request returns a 401, Git will currently fail with a confusing message saying that it got a 401, which is not very descriptive. Currently if a user wants to use Git over HTTP, they have to use one URL with the username in the URL (e.g. "http://user@host.com/repo.git") for write access and another without the username for unauthenticated read access (unless they want to be prompted for the password each time). However, since the HTTP servers will return a 401 if an action requires authentication, we can prompt for username and password if we see this, allowing us to use a single URL for both purposes. This patch changes http_request to prompt for the username and password, then return HTTP_REAUTH so http_get_strbuf can try again. If it gets a 401 even when a user/pass is supplied, http_request will now return HTTP_NOAUTH which remote_curl can then use to display a more intelligent error message that is less confusing.

Smart push over HTTP: client side

2009-11-05T01:58:15Z

The git-remote-curl backend detects if the remote server supports the git-receive-pack service, and if so, runs git-send-pack in a pipe to dump the command and pack data as a single POST request. The advertisements from the server that were obtained during the discovery are passed into git-send-pack before the POST request starts. This permits git-send-pack to operate largely unmodified. For smaller packs (those under 1 MiB) a HTTP/1.0 POST with a Content-Length is used, permitting interaction with any server. The 1 MiB limit is arbitrary, but is sufficent to fit most deltas created by human authors against text sources with the occasional small binary file (e.g. few KiB icon image). The configuration option http.postBuffer can be used to increase (or shink) this buffer if the default is not sufficient. For larger packs which cannot be spooled entirely into the helper's memory space (due to http.postBuffer being too small), the POST request requires HTTP/1.1 and sets "Transfer-Encoding: chunked". This permits the client to upload an unknown amount of data in one HTTP transaction without needing to pregenerate the entire pack file locally. Signed-off-by: Shawn O.

http*: add helper methods for fetching objects (loose)

2009-06-06T18:03:11Z

The code handling the fetching of loose objects in http-push.c and http-walker.c have been refactored into new methods and a new struct (object_http_request) in http.c. They are not meant to be invoked elsewhere. The new methods in http.c are - new_http_object_request - process_http_object_request - finish_http_object_request - abort_http_object_request - release_http_object_request and the new struct is http_object_request. RANGER_HEADER_SIZE and no_pragma_header is no longer made available outside of http.c, since after the above changes, there are no other instances of usage outside of http.c. Remove members of the transfer_request struct in http-push.c and http-walker.c, including filename, real_sha1 and zret, as they are used no longer used. Move the methods append_remote_object_url() and get_remote_object_url() from http-push.c to http.c. Additionally, get_remote_object_url() is no longer defined only when USE_CURL_MULTI is defined, since non-USE_CURL_MULTI code in http.c uses it (namely, in new_http_object_request()). Refactor code from http-push.c::start_fetch_loose() and http-walker.c::start_object_fetch_request() that deals with the details of coming up with the filename to store the retrieved object, resuming a previously aborted request, and making a new curl request, into a new function, new_http_object_request(). Refactor code from http-walker.c::process_object_request() into the function, process_http_object_request(). Refactor code from http-push.c::finish_request() and http-walker.c::finish_object_request() into a new function, finish_http_object_request(). It returns the result of the move_temp_to_file() invocation. Add a function, release_http_object_request(), which cleans up object request data. http-push.c and http-walker.c invoke this function separately; http-push.c::release_request() and http-walker.c::release_object_request() do not invoke this function. Add a function, abort_http_object_request(), which unlink()s the object file and invokes release_http_object_request(). Update http-walker.c::abort_object_request() to use this.

http*: add helper methods for fetching packs

2009-06-06T18:03:11Z

The code handling the fetching of packs in http-push.c and http-walker.c have been refactored into new methods and a new struct (http_pack_request) in http.c. They are not meant to be invoked elsewhere. The new methods in http.c are - new_http_pack_request - finish_http_pack_request - release_http_pack_request and the new struct is http_pack_request. Add a function, new_http_pack_request(), that deals with the details of coming up with the filename to store the retrieved packfile, resuming a previously aborted request, and making a new curl request. Update http-push.c::start_fetch_packed() and http-walker.c::fetch_pack() to use this. Add a function, finish_http_pack_request(), that deals with renaming the pack, advancing the pack list, and installing the pack. Update http-push.c::finish_request() and http-walker.c::fetch_pack to use this. Update release_request() in http-push.c and http-walker.c to invoke release_http_pack_request() to clean up pack request helper data. The local_stream member of the transfer_request struct in http-push.c has been removed, as the packfile pointer will be managed in the struct http_pack_request.

http*: add http_get_info_packs

2009-06-06T18:03:11Z

http-push.c and http-walker.c no longer have to use fetch_index or setup_index; they simply need to use http_get_info_packs, a new http method, in their fetch_indices implementations. Move fetch_index() and rename to fetch_pack_index() in http.c; this method is not meant to be used outside of http.c. It invokes end_url_with_slash with base_url; apart from that change, the code is identical. Move setup_index() and rename to fetch_and_setup_pack_index() in http.c; this method is not meant to be used outside of http.c. Do not immediately set ret to 0 in http-walker.c::fetch_indices(); instead do it in the HTTP_MISSING_TARGET case, to make it clear that the HTTP_OK and HTTP_MISSING_TARGET cases both return 0.
