| * smart-http: Really never use Expect: 100-continueShawn O. Pearce2011-03-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libcurl may choose to try and use Expect: 100-continue for any type of POST, not just a Transfer: chunked-encoding type. Force it to disable this feature, as not all proxy servers support 100-continue and leaving it enabled can cause 1 second stalls during the negotiation phase of fetch-pack/upload-pack. In ("206b099d26 smart-http: Don't use Expect: 100-Continue") we tried to disable this for only large POST bodies, but it should be disabled for every POST body. Signed-off-by: Shawn O.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some HTTP/1.1 servers or proxies don't correctly implement the 100-Continue feature of HTTP/1.1. Its a difficult feature to implement right, and isn't commonly used by browsers, so many developers may not even be aware that their server (or proxy) doesn't honor it. Within the smart HTTP protocol for Git we only use this newer "Expect: 100-Continue" feature to probe for missing authentication before uploading a large payload like a pack file during push. If authentication is necessary, we expect the server to send the 401 Not Authorized response before the bulk data transfer starts, thus saving the client bandwidth during the retry. A different method to probe for working authentication is to send an empty command list (that is just "0000") to $URL/git-receive-pack. or $URL/git-upload-pack. All versions of both receive-pack and upload-pack since the introduction of smart HTTP in Git 1.6.6 cleanly accept just a flush-pkt under --stateless-rpc mode, and exit with success. If HTTP level authentication is successful, the backend will return an empty response, but with HTTP status code 200. This enables the client to continue with the transfer. Signed-off-by: Shawn O.

It is possible for users to pass a URL with a trailing slash to remote-curl, by, say, setting it in remote.<name>.url in their git config. The resulting requests have an empty path component (//) and may break implementations of the http git protocol.

* | | | Prompt for a username when an HTTP request 401sScott Chacon2010-04-01

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.

* | Allow curl to rewind the RPC read bufferMartin Storsjö2009-12-01
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | When using multi-pass authentication methods, the curl library may need to rewind the read buffers used for providing data to HTTP POST, if data has been output before a 401 error is received. This is needed only when the first request (when the multi-pass authentication method isn't initialized and hasn't received its challenge yet) for a certain curl session is a chunked HTTP POST. As long as the current rpc read buffer is the first one, we're able to rewind without need for additional buffering. The curl library currently starts sending data without waiting for a response to the Expect: 100-continue header, due to a bug in curl that exists up to curl version 7.19.7. If the HTTP server doesn't handle Expect: 100-continue headers properly (e.g. Lighttpd), the library has to start sending data without knowing if the request will be successfully authenticated. In this case, this rewinding solution is not sufficient - the whole request will be sent before the 401 error is received. Signed-off-by: Martin Storsjo <martin@martin.st> Acked-by: Shawn O.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The git-remote-curl backend detects if the remote server supports the git-upload-pack service, and if so, runs git-fetch-pack locally in a pipe to generate the want/have commands. The advertisements from the server that were obtained during the discovery are passed into git-fetch-pack before the POST request starts, permitting server capability discovery and enablement. Common objects that are discovered are appended onto the request as have lines and are sent again on the next request. This allows the remote side to reinitialize its in-memory list of common objects during the next request. Because all requests are relatively short, below git-remote-curl's 1 MiB buffer limit, requests will use the standard Content-Length header and be valid HTTP/1.0 POST requests. This makes the fetch client more tolerant of proxy servers which don't support HTTP/1.1 or the chunked transfer encoding. Signed-off-by: Shawn O.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
