|\ | | | | | | | | | | | | | | | | Further clean-up to the http codepath that picks up results after cURL library is done with one request slot. * jk/maint-http-init-not-in-result-handler: http: do not set up curl auth after a 401 remote-curl: do not call run_slot repeatedly
| * http: do not set up curl auth after a 401Jeff King2012-10-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we get an http 401, we prompt for credentials and put them in our global credential struct. We also feed them to the curl handle that produced the 401, with the intent that they will be used on a retry. When the code was originally introduced in commit 42653c0, this was a necessary step. However, since dfa1725, we always feed our global credential into every curl handle when we initialize the slot with get_active_slot. So every further request already feeds the credential to curl. Moreover, accessing the slot here is somewhat dubious. After the slot has produced a response, we don't actually control it any more. If we are using curl_multi, it may even have been re-initialized to handle a different request. It just so happens that we will reuse the curl handle within the slot in such a case, and that because we only keep one global credential, it will be the one we want. So the current code is not buggy, but it is misleading. By cleaning it up, we can remove the slot argument entirely from handle_curl_result, making it much more obvious that slots should not be accessed after they are marked as finished.

| * remote-curl: do not call run_slot repeatedlyJeff King2012-10-121-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b81401c (http: prompt for credentials on failed POST) taught post_rpc to call run_slot in a loop in order to retry a request after asking the user for credentials. However, after a call to run_slot we will have called finish_active_slot. This means we have released the slot, and we should no longer look at it. As it happens, this does not cause any bugs in the current code, since we know that we are not using curl_multi in this code path, and therefore nobody will have taken over our slot in the meantime. However, it is good form to actually call get_active_slot again. It also future proofs us against changes in the http code. We can do this by jumping back to a retry label at the top of our function. We just need to reorder a few setup lines that should not be repeated; everything else within the loop is either idempotent, needs to be repeated, or in a path we do not follow (e.g., we do not even try when large_request is set, because we don't know how much data we might have streamed from our helper program).

The http code will fill in the details of how the request went, and we can access those details even after the slot has been cleaned up. Commit 8809703 (http: factor out http error code handling) switched us from accessing our local results struct directly to accessing it via the "results" pointer of the slot. That means we're accessing the slot after it has been marked as finished, defeating the whole purpose of keeping the results storage separate. Most of the time this doesn't matter, as finishing the slot does not actually clean up the pointer. However, when using curl's multi interface with the dumb-http revision walker, we might actually start a new request before handing control back to the original caller. In that case, we may reuse the slot, zeroing its results pointer, and leading the original caller to segfault while looking for its results inside the slot. Instead, we need to pass a pointer to our local results storage to the handle_curl_result function, rather than relying on the pointer in the slot struct. This matches what the original code did before the refactoring (which did not use a separate function, and therefore just accessed the results struct directly).

However, some misconfigured dumb-only servers may not like the initial request by a smart client, as it contains a query string. Until recently, commit 703e6e7 worked around this by making a second request. However, that commit was recently reverted due to its side effect of masking the initial request's error code. Since git has had that workaround for several years, we don't know exactly how many such misconfigured servers are out there. The reversion of 703e6e7 assumes they are rare enough not to worry about. Still, that reversion leaves somebody who does run into such a server with no escape hatch at all. Let's give them an environment variable they can tweak to perform the "dumb" request. This is intentionally not a documented interface. It's overly simple and is really there for debugging in case somebody does complain about git not working with their server. A real user-facing interface would entail a per-remote or per-URL config variable. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some HTTP servers try to use gzip compression on the /info/refs request to save transfer bandwidth. Repositories with many tags may find the /info/refs request can be gzipped to be 50% of the original size due to the few but often repeated bytes used (hex SHA-1 and commonly digits in tag names). For most HTTP requests enable "Accept-Encoding: gzip" ensuring the /info/refs payload can use this encoding format. Only request gzip encoding from servers. Although deflate is supported by libcurl, most servers have standardized on gzip encoding for compression as that is what most browsers support. Asking for deflate increases request sizes by a few bytes, but is unlikely to ever be used by a server. Disable the Accept-Encoding header on probe RPCs as response bodies are supposed to be exactly 4 bytes long, "0000". The HTTP headers requesting and indicating compression use more space than the data transferred in the body. Signed-off-by: Shawn O.

|/ | | | | | | | | | | | | | | | | | | | | | This reverts commit 703e6e76a14825e5b0c960d525f34e607154b4f7. Retrying without the query parameter was added as a workaround for a single broken HTTP server at git.debian.org[1]. The server was misconfigured to route every request with a query parameter into gitweb.cgi. Admins fixed the server's configuration within 16 hours of the bug report to the Git mailing list, but we still patched Git with this fallback and have been paying for it since. Most Git hosting services configure the smart HTTP protocol and the retry logic confuses users when there is a transient HTTP error as Git dropped the real error from the smart HTTP request. Removing the retry makes root causes easier to identify. [1] http://thread.gmane.org/gmane.comp.version-control.git/137609 Signed-off-by: Shawn O.

* http: prompt for credentials on failed POSTJeff King2012-08-271-8/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All of the smart-http GET requests go through the http_get_* functions, which will prompt for credentials and retry if we see an HTTP 401. POST requests, however, do not go through any central point. Moreover, it is difficult to retry in the general case; we cannot assume the request body fits in memory or is even seekable, and we don't know how much of it was consumed during the attempt. Most of the time, this is not a big deal; for both fetching and pushing, we make a GET request before doing any POSTs, so typically we figure out the credentials during the first request, then reuse them during the POST. However, some servers may allow a client to get the list of refs from receive-pack without authentication, and then require authentication when the client actually tries to POST the pack. This is not ideal, as the client may do a non-trivial amount of work to generate the pack (e.g., delta-compressing objects). However, for a long time it has been the recommended example configuration in git-http-backend(1) for setting up a repository with anonymous fetch and authenticated push. This setup has always been broken without putting a username into the URL. Prior to commit 986bbc0, it did work with a username in the URL, because git would prompt for credentials before making any requests at all. However, post-986bbc0, it is totally broken. Since it has been advertised in the manpage for some time, we should make sure it works. Unfortunately, it is not as easy as simply calling post_rpc again when it fails, due to the input issue mentioned above. However, we can still make this specific case work by retrying in two specific instances: 1. If the request is large (bigger than LARGE_PACKET_MAX), we will first send a probe request with a single flush packet. Since this request is static, we can freely retry it. 2. If the request is small and we are not using gzip, then we have the whole thing in-core, and we can freely retry. That means we will not retry in some instances, including: 1. If we are using gzip. However, we only do so when calling git-upload-pack, so it does not apply to pushes. 2. If we have a large request, the probe succeeds, but then the real POST wants authentication. This is an extremely unlikely configuration and not worth worrying about. While it might be nice to cover those instances, doing so would be significantly more complex for very little real-world gain. In the long run, we will be much better off when curl learns to internally handle authentication as a callback, and we can cleanly handle all cases that way.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The send_pack function gets a "progress" flag saying "yes, definitely show progress" or "no, definitely do not show progress". This gets set properly by transport_push when send_pack is called directly. However, when the send-pack command is executed separately (as it is for the remote-curl helper), there is no way to tell it "definitely do this". As a result, we do not properly respect "git push --no-progress" for smart-http remotes; you will still get progress if stderr is a tty. This patch teaches send-pack --progress and --no-progress, and teaches remote-curl to pass the appropriate option to override send-pack's isatty check. This fixes the --no-progress case above, and as a bonus, also makes "git push --progress" work when stderr is not a tty.

However, when we have an empty repository, there are no refs, and therefore receive-pack writes a fake ref "capabilities^{}" with the capabilities afterwards. On the client side, git reads the result with get_remote_heads(). We pick the capabilities from the end of the line, and then call check_ref() to make sure the ref name is valid. We see that it isn't, and don't bother adding it to our list of refs. However, the call to check_ref() is enabled by passing the REF_NORMAL flag to get_remote_heads. For the regular git transport, we pass REF_NORMAL in get_refs_via_connect() if we are doing a push (since only receive-pack uses this fake ref). But in remote-curl, we never use this flag, and we accept the fake ref as a real one, passing it back from the helper to the parent git-push. Most of the time this bug goes unnoticed, as the fake ref won't match our refspecs. However, if "--mirror" is used, then we see it as remote cruft to be pruned, and try to pass along a deletion refspec for it. Of course this refspec has bogus syntax (because of the ^{}), and the helper complains, aborting the push. Let's have remote-curl mirror what the builtin get_refs_via_connect() does (at least for the case of using git protocol; we can leave the dumb info/refs reader as it is). This also fixes pushing with --mirror to a smart-http remote that uses alternates. The fake ".have" refs the server gives to avoid unnecessary network transfer has a similar bad interactions with the machinery.

It assumed that if you had a username in your URL, you would also want a password, and asked for it before making any http requests. However, this could interfere with the use of .netrc (see 986bbc08 for details). And it was also unnecessary, since the http fetching code had learned to recognize an HTTP 401 and prompt the user then. Furthermore, the proactive prompt could interfere with the usage of .netrc (see 986bbc08 for details). Unfortunately, the http push-over-DAV code never learned to recognize HTTP 401, and so was broken by this change.

This will work for a smart-http server, or a dumb server which ignores extra parameters when fetching files. If that fails, we retry without the extra parameter to remain compatible with dumb servers which didn't like our first request. If the server returned a "401 Unauthorized", indicating that the credentials we provided were not good, there is not much point in retrying. With the current code, we just waste an extra round trip to the HTTP server before failing. But as the http code becomes smarter about throwing away rejected credentials and re-prompting the user for new ones (which it will later in this series), this will become more confusing. At some point we will stop asking for credentials to retry smart http, and will be asking for credentials to retry dumb http. So now we're not only wasting an extra HTTP round trip for something that is unlikely to work, but we're making the user re-type their password for it.

Adding a new command line option to receive-pack and feed it from send-pack is not an acceptable way to add features, as there is no guarantee that your updated send-pack will be talking to updated receive-pack. New features need to be added via the capability mechanism negotiated over the protocol. Signed-off-by: Junio C Hamano <gitster@pobox.com>

But the interface defined in zlib.h to communicate with inflate/deflate limits avail_in (how many bytes of input are we calling zlib with) and avail_out (how many bytes of output from zlib are we ready to accept) fields effectively to 4GB by defining their type to be uInt. In many places in our code, we allocate a large buffer (e.g. mmap'ing a large loose object file) and tell zlib its size by assigning the size to avail_in field of the stream, but that will truncate the high octets of the real size. The worst part of this story is that we often pass around z_stream (the state object used by zlib) to keep track of the number of used bytes in input/output buffer by inspecting these two fields, which practically limits our callchain to the same 4GB limit. Wrap z_stream in another structure git_zstream that can express avail_in and avail_out in unsigned long. For now, just die() when the caller gives a size that cannot be given to a single zlib call. In later patches in the series, we would make git_inflate() and git_deflate() internally loop to give callers an illusion that our "improved" version of zlib interface can operate on a buffer larger than 4GB in one go.

There is only one caller that cares about the status from deflateEnd(). Introduce git_deflate_end_gently() to let that sole caller retrieve the status and act on it (i.e. die) for now, but we would probably want to make inflate_end/deflate_end die when they ran out of memory and get rid of the _gently() kind.

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