* http.c: new functions for the http APIMike Hommey2009-06-06
| | | | | | | | | | | | | | | | | | The new functions added are: - http_request() (internal function) - http_get_strbuf() - http_get_file() - http_error() http_get_strbuf and http_get_file allow respectively to retrieve contents of an URL to a strbuf or an opened file handle. http_error prints out an error message containing the URL and the curl error (in curl_errorstr).

* http*: move common variables and macros to http.[ch]Tay Ray Chuan2009-06-06
| | | | | | | | | | | | | | | | Move RANGE_HEADER_SIZE to http.h. Create no_pragma_header, the curl header list containing the header "Pragma:" in http.[ch]. It is allocated in http_init, and freed in http_cleanup. This replaces the no_pragma_header in http-push.c, and the no_pragma_header member in walker_data in http-walker.c. Create http_is_verbose. It is to be used by methods in http.c, and is modified at the entry points of http.c's users, namely http-push.c (when parsing options) and http-walker.c (in get_http_walker).

* Allow curl to rewind the read buffersMartin Storsjö2009-04-02
| | | | | | | | | | | | | | | | | | | | | When using multi-pass authentication methods, the curl library may need to rewind the read buffers (depending on how much already has been fed to the server) used for providing data to HTTP PUT, POST or PROPFIND, and in order to allow the library to do so, we need to tell it how by providing either an ioctl callback or a seek callback. This patch adds an ioctl callback, which should be usable on older curl versions (since 7.12.3) than the seek callback (introduced in curl 7.18.0). Some HTTP servers (such as Apache) give an 401 error reply immediately after receiving the headers (so no data has been read from the read buffers, and thus no rewinding is needed), but other servers (such as Lighttpd) only replies after the whole request has been sent and all data has been read from the read buffers, making rewinding necessary.

* Work around gcc warnings from curl headersJunio C Hamano2008-07-04
| | | | | | | | | | | | | | After master.k.org upgrade, I started seeing these warning messages: transport.c: In function 'get_refs_via_curl': transport.c:458: error: call to '_curl_easy_setopt_err_write_callback' declared with attribute warning: curl_easy_setopt expects a curl_write_callback argument for this option It appears that the curl header wants to enforce the function signature for callback function given to curl_easy_setopt() to be compatible with that of (*curl_write_callback) or fwrite. This patch seems to work the issue around. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Make walker.fetch_ref() take a struct ref.Daniel Barkalow2008-04-26
| | | | | | | | | | | | | | | | This simplifies a few things, makes a few things slightly more complicated, but, more importantly, allows that, when struct ref can represent a symref, http_fetch_ref() can return one. Incidentally makes the string that http_fetch_ref() gets include "refs/" (if appropriate), because that's how the name field of struct ref works. As far as I can tell, the usage in walker:interpret_target() wouldn't have worked previously, if it ever would have been used, which it wouldn't (since the fetch process uses the hash instead of the name of the ref there).

* Set proxy override with http_init()Mike Hommey2008-02-27
| | | | | | | | | | | | | | | | | | | | In transport.c, proxy setting (the one from the remote conf) was set through curl_easy_setopt() call, while http.c already does the same with the http.proxy setting. We now just use this infrastructure instead, and make http_init() now take the struct remote as argument so that it can take the http_proxy setting from there, and any other property that would be added later. At the same time, we make get_http_walker() take a struct remote argument too, and pass it to http_init(), which makes remote defined proxy be used for more than get_refs_via_curl(). We leave out http-fetch and http-push, which don't use remotes for the moment, purposefully.

* Cleanup variables in http.[ch]Mike Hommey2007-12-09

* Make function to refill http queue a callbackDaniel Barkalow2007-09-19
| | | | | | | | | | | This eliminates the last function provided by the code using http.h as a global symbol, so it should be possible to have multiple programs using http.h in the same executable, and it also adds an argument to that callback, so that info can be passed into the callback without being global.

* http-fetch: Disable use of curl multi support for libcurl < 7.16.Alexandre Julliard2007-05-03
| | | | | | | | | | curl_multi_remove_handle() is broken in libcurl < 7.16, in that it doesn't correctly update the active handles count when a request is aborted. This causes the transfer to hang forever waiting for the handle count to become less than the number of active requests.

* Work around http-fetch built with cURL 7.16.0Junio C Hamano2006-12-27
| | | | | | | | | | | It appears that curl_easy_duphandle() from libcurl 7.16.0 returns a curl session handle which fails GOOD_MULTI_HANDLE() check in curl_multi_add_handle(). This causes fetch_ref() to fail because start_active_slot() cannot start the request. For now, check for 7.16.0 to work this issue around. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Patch for http-fetch.c and older curl releasesArt Haas2006-09-20
| | | | | | | | | | | | | | | | Older curl releases do not define CURLE_HTTP_RETURNED_ERROR, they use CURLE_HTTP_NOT_FOUND instead. Newer curl releases keep the CURLE_HTTP_NOT_FOUND definition but using a -DCURL_NO_OLDIES preprocessor flag the old name will not be present in the 'curl.h' header. This patch makes our code written for newer releases of the curl library but allow compiling against an older curl (older than 0x070a03) by defining the missing CURLE_HTTP_RETURNED_ERROR as a synonym for CURLE_HTTP_NOT_FOUND.

* http-fetch: Abort requests for objects which arrived in packsMark Wooding2006-02-07
| | | | | | | | | | In fetch_object, there's a call to release an object request if the object mysteriously arrived, say in a pack. Unfortunately, the fetch attempt for this object might already be in progress, and we'll leak the descriptor. Instead, try to tidy away the request.

* Isolate shared HTTP request functionalityNick Hengeveld2005-11-19
Move shared HTTP request functionality out of http-fetch and http-push, and replace the two fwrite_buffer/fwrite_buffer_dynamic functions with one fwrite_buffer function that does dynamic buffering. Use slot callbacks to process responses to fetch object transfer requests and push transfer requests, and put all of http-push into an #ifdef check for curl multi support.
