2010-04-19http-fetch: Use temporary files for pack-*.idx until verifiedLibravatar Shawn O. Pearce1-17/+39
Verify that a downloaded pack-*.idx file is consistent and valid as an index file before we rename it into its final destination. This prevents a corrupt index file from later being treated as a usable file, confusing readers. Check that we do not have the pack index file before invoking fetch_pack_index(); that way, we can do without the has_pack_index() check in fetch_pack_index(). Signed-off-by: Shawn O.

2010-04-19http-fetch: Use index-pack rather than verify-pack to check packsLibravatar Shawn O. Pearce1-7/+37
To ensure we don't leave a corrupt pack file positioned as though it were a valid pack file, run index-pack on the temporary pack before we rename it to its final name. If index-pack crashes out when it discovers file corruption (e.g. GitHub's error HTML at the end of the file), simply delete the temporary files to cleanup. By waiting until the pack has been validated before we move it to its final name, we eliminate a race condition where another concurrent reader might try to access the pack at the same time that we are still trying to verify its not corrupt. Switching from verify-pack to index-pack is a change in behavior, but it should turn out better for users. The index-pack algorithm tries to minimize disk seeks, as well as the number of times any given object is inflated, by organizing its work along delta chains. The verify-pack logic does not attempt to do this, thrashing the delta base cache and the filesystem cache. By recreating the index file locally, we also can automatically upgrade from a v1 pack table of contents to v2. This makes the CRC32 data available for use during later repacks, even if the server didn't have them on hand. Signed-off-by: Shawn O.

2010-04-19Allow parse_pack_index on temporary filesLibravatar Shawn O. Pearce1-1/+1
The easiest way to verify a pack index is to open it through the standard parse_pack_index function, permitting the header check to happen when the file is mapped. However, the dumb HTTP client needs to verify a pack index before its moved into its proper file name within the objects/pack directory, to prevent a corrupt index from being made available. So permit the caller to specify the exact path of the index file. For now we're still using the final destination name within the sole call site in http.c, but eventually we will start to parse the temporary path instead. Signed-off-by: Shawn O.

2010-04-19http.c: Remove unnecessary strdup of sha1_to_hex resultLibravatar Shawn O. Pearce1-4/+2
Most of the time the dumb HTTP transport is run without the verbose flag set, so we only need the result of sha1_to_hex(sha1) once, to construct the pack URL. Don't bother with an unnecessary malloc, copy, free chain of this buffer. If verbose is set, we'll format the SHA-1 twice now. But this tiny extra CPU time spent is nothing compared to the slowdown that is usually imposed by the verbose messages being sent to the tty, and is entirely trivial compared to the latency involved with the remote HTTP server sending something as big as a pack file.

2010-04-17http.c: Don't store destination name in request structuresLibravatar Shawn O. Pearce1-8/+6
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.

The filename variable here is pointing to a block of memory that was allocated by sha1_file.c and is also held in a static variable scoped within the sha1_pack_name() function. Doing a free() here is returning that memory to the allocator while we might still try to reuse it on a subsequent sha1_pack_name() invocation. That's not acceptable, so don't free it.

2010-04-01Prompt for a username when an HTTP request 401sLibravatar Scott Chacon1-2/+20
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.

2009-12-29Remove http.authAnyLibravatar Junio C Hamano1-16/+1
Back when the feature to use different HTTP authentication methods was originally written, it needed an extra HTTP request for everything when the feature was in effect, because we didn't reuse curl sessions. However, b8ac923 (Add an option for using any HTTP authentication scheme, not only basic, 2009-11-27) builds on top of an updated codebase that does reuse curl sessions; there is no need to manually avoid the extra overhead by making this configurable anymore.

2009-11-27Add an option for using any HTTP authentication scheme, not only basicLibravatar Martin Storsjö1-0/+22
This adds the configuration option http.authAny (overridable with the environment variable GIT_HTTP_AUTH_ANY), for instructing curl to allow any HTTP authentication scheme, not only basic (which sends the password in plaintext). When this is enabled, curl has to do double requests most of the time, in order to discover which HTTP authentication method to use, which lowers the performance slightly. Therefore this isn't enabled by default. One example of another authentication scheme to use is digest, which doesn't send the password in plaintext, but uses a challenge-response mechanism instead. Using digest authentication in practice requires at least curl 7.18.1, due to bugs in the digest handling in earlier versions of curl.

2009-11-04Smart push over HTTP: client sideLibravatar Shawn O. Pearce1-3/+10
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.

Make http.c::fetch_pack_index() no longer check for the remote pack with a HEAD request before fetching the corresponding pack index file. Not only does sending a HEAD request before we do a GET incur a performance penalty, it does not offer any significant error- prevention advantages (pack fetching in the *_http_pack_request() methods is capable of handling any errors on its own).

Set the members callback_func and callback_data of freq->slot to NULL when releasing a http_object_request. release_active_slot() is also invoked on the slot to remove the curl handle associated with the slot from the multi stack (CURLM *curlm in http.c).

Make append_remote_object_url() (and by implication, get_remote_object_url) use end_url_with_slash() to ensure that the url ends with a slash.

This fixes an issue introduced in 5424bc5 ("http*: add helper methods for fetching objects (loose)"), where the append_remote_object_url() implementation in http-push.c, which assumed that urls end with a slash, was replaced by another one in http.c, which assumed urls did not end with a slash.

Add a configuration option, http.sslCertPasswordProtected, and associated environment variable, GIT_SSL_CERT_PASSWORD_PROTECTED, to enable SSL client certificate password prompt from within git.

If an SSL client certificate is enabled (via http.sslcert or GIT_SSL_CERT), prompt for the certificate password rather than defaulting to OpenSSL's password prompt. This causes the prompt to only appear once each run. Previously, OpenSSL prompted the user *many* times, causing git to be unusable over HTTPS with client-side certificates. Note that the password is stored in memory in the clear while the program is running. This may be a security problem if git crashes and core dumps. The user is always prompted, even if the certificate is not encrypted. This should be fine; unencrypted certificates are rare and a security risk anyway.

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.

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).

2009-04-02Allow curl to rewind the read buffersLibravatar Martin Storsjö1-0/+19
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.

Besides, we have already called easy_setopt with the option before coming to this function if it was available, so there is no need to repeat it here. Signed-off-by: Junio C Hamano <gitster@pobox.com>
