2018-10-07fetch: do not list refs if fetching only hashesLibravatar Jonathan Tan1-0/+15
If only hash literals are given on a "git fetch" command-line, tag following is not requested, and the fetch is done using protocol v2, a list of refs is not required from the remote. Therefore, optimize by invoking transport_get_remote_refs() only if we need the refs. Signed-off-by: Jonathan Tan <jonathantanmy@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-09-24t5551: compare sorted cookies filesLibravatar Thomas Gummerer1-2/+2
In t5551 we check that we save cookies correctly to a file when http.cookiefile and http.savecookies are set. To do so we create an expect file that expects the cookies in a certain order. However after e2ef8d6fa ("cookies: support creation-time attribute for cookies", 2018-08-28) in curl.git (released in curl 7.61.1) that order changed. We document the file format as "Netscape/Mozilla cookie file format (see curl(1))", so any format produced by libcurl should be fine here. Sort the files, to be agnostic to the order of the cookies, and make the test pass with both curl versions > 7.61.1 and earlier curl versions.

2018-08-01fetch-pack: unify ref in and out paramLibravatar Jonathan Tan1-0/+18
When a user fetches: - at least one up-to-date ref and at least one non-up-to-date ref, - using HTTP with protocol v0 (or something else that uses the fetch command of a remote helper) some refs might not be updated after the fetch. This bug was introduced in commit 989b8c4452 ("fetch-pack: put shallow info in output parameter", 2018-06-28) which allowed transports to report the refs that they have fetched in a new out-parameter "fetched_refs". If they do so, transport_fetch_refs() makes this information available to its caller. Users of "fetched_refs" rely on the following 3 properties: (1) it is the complete list of refs that was passed to transport_fetch_refs(), (2) it has shallow information (REF_STATUS_REJECT_SHALLOW set if relevant), and (3) it has updated OIDs if ref-in-want was used (introduced after 989b8c4452). In an effort to satisfy (1), whenever transport_fetch_refs() filters the refs sent to the transport, it re-adds the filtered refs to whatever the transport supplies before returning it to the user. However, the implementation in 989b8c4452 unconditionally re-adds the filtered refs without checking if the transport refrained from reporting anything in "fetched_refs" (which it is allowed to do), resulting in an incomplete list, no longer satisfying (1). An earlier effort to resolve this [1] solved the issue by readding the filtered refs only if the transport did not refrain from reporting in "fetched_refs", but after further discussion, it seems that the better solution is to revert the API change that introduced "fetched_refs". This API change was first suggested as part of a ref-in-want implementation that allowed for ref patterns and, thus, there could be drastic differences between the input refs and the refs actually fetched [2]; we eventually decided to only allow exact ref names, but this API change remained even though its necessity was decreased. Therefore, revert this API change by reverting commit 989b8c4452, and make receive_wanted_refs() update the OIDs in the sought array (like how update_shallow() updates shallow information in the sought array) instead. A test is also included to show that the user-visible bug discussed at the beginning of this commit message no longer exists.

2018-07-12t/lib-httpd: avoid occasional failures when checking access.logLibravatar SZEDER Gábor1-2/+1
The last test of 't5561-http-backend.sh', 'server request log matches test results' may fail occasionally, because the order of entries in Apache's access log doesn't match the order of requests sent in the previous tests, although all the right requests are there. I saw it fail on Travis CI five times in the span of about half a year, when the order of two subsequent requests was flipped, and could trigger the failure with a modified Git. However, I was unable to trigger it with stock Git on my machine. Three tests in 't5541-http-push-smart.sh' and 't5551-http-fetch-smart.sh' check requests in the log the same way, so they might be prone to a similar occasional failure as well. When a test sends a HTTP request, it can continue execution after 'git-http-backend' fulfilled that request, but Apache writes the corresponding access log entry only after 'git-http-backend' exited. Some time inevitably passes between fulfilling the request and writing the log entry, and, under unfavourable circumstances, enough time might pass for the subsequent request to be sent and fulfilled by a different Apache thread or process, and then Apache writes access log entries racily. This effect can be exacerbated by adding a bit of variable delay after the request is fulfilled but before 'git-http-backend' exits, e.g. like this: diff --git a/http-backend.c b/http-backend.c index f3dc218b2..bbf4c125b 100644 --- a/http-backend.c +++ b/http-backend.c @@ -709,5 +709,7 @@ int cmd_main(int argc, const char **argv) max_request_buffer); cmd->imp(&hdr, cmd_arg); + if (getpid() % 2) + sleep(1); return 0; } This delay considerably increases the chances of log entries being written out of order, and in turn makes t5561's last test fail almost every time. Alas, it doesn't seem to be enough to trigger a similar failure in t5541 and t5551. So, since we can't just rely on the order of access log entries always corresponding the order of requests, make checking the access log more deterministic by sorting (simply lexicographically) both the stripped access log entries and the expected entries before the comparison with 'test_cmp'. This way the order of log entries won't matter and occasional out-of-order entries won't trigger a test failure, but the comparison will still notice any unexpected or missing log entries. OTOH, this sorting will make it harder to identify from which test an unexpected log entry came from or which test's request went missing. Therefore, in case of an error include the comparison of the unsorted log enries in the test output as well. And since all this should be performed in four tests in three test scripts, put this into a new helper function 'check_access_log' in 't/lib-httpd.sh'.

2018-05-23remote-curl: accept all encodings supported by curlLibravatar Brandon Williams1-4/+9
Configure curl to accept all encodings which curl supports instead of only accepting gzip responses. This fixes an issue when using an installation of curl which is built without the "zlib" feature. Since aa90b9697 (Enable info/refs gzip decompression in HTTP client, 2012-09-19) we end up requesting "gzip" encoding anyway despite libcurl not being able to decode it. Worse, instead of getting a clear error message indicating so, we end up falling back to "dumb" http, producing a confusing and difficult to debug result. Since curl doesn't do any checking to verify that it supports the a requested encoding, instead set the curl option `CURLOPT_ENCODING` with an empty string indicating that curl should send an "Accept-Encoding" header containing only the encodings supported by curl.

2016-12-06http: always update the base URL for redirectsLibravatar Jeff King1-0/+4
If a malicious server redirects the initial ref advertisement, it may be able to leak sha1s from other, unrelated servers that the client has access to. For example, imagine that Alice is a git user, she has access to a private repository on a server hosted by Bob, and Mallory runs a malicious server and wants to find out about Bob's private repository. Mallory asks Alice to clone an unrelated repository from her over HTTP. When Alice's client contacts Mallory's server for the initial ref advertisement, the server issues an HTTP redirect for Bob's server. Alice contacts Bob's server and gets the ref advertisement for the private repository. If there is anything to fetch, she then follows up by asking the server for one or more sha1 objects. But who is the server? If it is still Mallory's server, then Alice will leak the existence of those sha1s to her. Since commit c93c92f30 (http: update base URLs when we see redirects, 2013-09-28), the client usually rewrites the base URL such that all further requests will go to Bob's server. But this is done by textually matching the URL. If we were originally looking for "http://mallory/repo.git/info/refs", and we got pointed at "http://bob/other.git/info/refs", then we know that the right root is "http://bob/other.git". If the redirect appears to change more than just the root, we punt and continue to use the original server. E.g., imagine the redirect adds a URL component that Bob's server will ignore, like "http://bob/other.git/info/refs?dummy=1". We can solve this by aborting in this case rather than silently continuing to use Mallory's server. In addition to protecting from sha1 leakage, it's arguably safer and more sane to refuse a confusing redirect like that in general. For example, part of the motivation in c93c92f30 is avoiding accidentally sending credentials over clear http, just to get a response that says "try again over https". So even in a non-malicious case, we'd prefer to err on the side of caution. The downside is that it's possible this will break a legitimate but complicated server-side redirection scheme. The setup given in the newly added test does work, but it's convoluted enough that we don't need to care about it. A more plausible case would be a server which redirects a request for "info/refs?service=git-upload-pack" to just "info/refs" (because it does not do smart HTTP, and for some reason really dislikes query parameters). Right now we would transparently downgrade to dumb-http, but with this patch, we'd complain (and the user would have to set GIT_SMART_HTTP=0 to fetch).

2016-11-18remote-curl: don't hang when a server dies before any outputLibravatar David Turner1-0/+30
In the event that a HTTP server closes the connection after giving a 200 but before giving any packets, we don't want to hang forever waiting for a response that will never come. Instead, we should die immediately. One case where this happens is when attempting to fetch a dangling object by its object name. In this case, the server dies before sending any data. Prior to this patch, fetch-pack would wait for data from the server, and remote-curl would wait for fetch-pack, causing a deadlock. Despite this patch, there is other possible malformed input that could cause the same deadlock (e.g. a half-finished pktline, or a pktline but no trailing flush). There are a few possible solutions to this: 1. Allowing remote-curl to tell fetch-pack about the EOF (so that fetch-pack could know that no more data is coming until it says something else). This is tricky because an out-of-band signal would be required, or the http response would have to be re-framed inside another layer of pkt-line or something. 2. Make remote-curl understand some of the protocol. It turns out that in addition to understanding pkt-line, it would need to watch for ack/nak. This is somewhat fragile, as information about the protocol would end up in two places. Also, pkt-lines which are already at the length limit would need special handling. Both of these solutions would require a fair amount of work, whereas this hack is easy and solves at least some of the problem. Still to do: it would be good to give a better error message than "fatal: The remote end hung up unexpectedly".

However, this test would also succeed if the configuration required only one header.

2016-04-27http: support sending custom HTTP headersLibravatar Johannes Schindelin1-0/+7
We introduce a way to send custom HTTP headers with all requests. This allows us, for example, to send an extra token from build agents for temporary access to private repositories. (This is the use case that triggered this patch.) This feature can be used like this: git -c http.extraheader='Secret: sssh!' fetch $URL $REF Note that `curl_easy_setopt(..., CURLOPT_HTTPHEADER, ...)` takes only a single list, overriding any previous call. This means we have to collect _all_ of the headers we want to use into a single list, and feed it to cURL in one shot. Since we already unconditionally set a "pragma" header when initializing the curl handles, we can add our new headers to that list. For callers which override the default header list (like probe_rpc), we provide `http_copy_default_headers()` so they can do the same trick.

2015-05-25http-backend: spool ref negotiation requests to bufferLibravatar Jeff King1-0/+11
When http-backend spawns "upload-pack" to do ref negotiation, it streams the http request body to upload-pack, who then streams the http response back to the client as it reads. In theory, git can go full-duplex; the client can consume our response while it is still sending the request. In practice, however, HTTP is a half-duplex protocol. Even if our client is ready to read and write simultaneously, we may have other HTTP infrastructure in the way, including the webserver that spawns our CGI, or any intermediate proxies. In at least one documented case[1], this leads to deadlock when trying a fetch over http. What happens is basically: 1. Apache proxies the request to the CGI, http-backend. 2. http-backend gzip-inflates the data and sends the result to upload-pack. 3. upload-pack acts on the data and generates output over the pipe back to Apache. Apache isn't reading because it's busy writing (step 1). This works fine most of the time, because the upload-pack output ends up in a system pipe buffer, and Apache reads it as soon as it finishes writing. But if both the request and the response exceed the system pipe buffer size, then we deadlock (Apache blocks writing to http-backend, http-backend blocks writing to upload-pack, and upload-pack blocks writing to Apache). We need to break the deadlock by spooling either the input or the output. In this case, it's ideal to spool the input, because Apache does not start reading either stdout _or_ stderr until we have consumed all of the input. So until we do so, we cannot even get an error message out to the client. The solution is fairly straight-forward: we read the request body into an in-memory buffer in http-backend, freeing up Apache, and then feed the data ourselves to upload-pack. But there are a few important things to note: 1. We limit the in-memory buffer to prevent an obvious denial-of-service attack. This is a new hard limit on requests, but it's unlikely to come into play. The default value is 10MB, which covers even the ridiculous 100,000-ref negotation in the included test (that actually caps out just over 5MB). But it's configurable on the off chance that you don't mind spending some extra memory to make even ridiculous requests work. 2. We must take care only to buffer when we have to. For pushes, the incoming packfile may be of arbitrary size, and we should connect the input directly to receive-pack. There's no deadlock problem here, though, because we do not produce any output until the whole packfile has been read. For upload-pack's initial ref advertisement, we similarly do not need to buffer. Even though we may generate a lot of output, there is no request body at all (i.e., it is a GET, not a POST).

2015-03-12upload-pack: fix transfer.hiderefs over smart-httpLibravatar Jeff King1-0/+11
When upload-pack advertises the refs (either for a normal, non-stateless request, or for the initial contact in a stateless one), we call for_each_ref with the send_ref function as its callback. send_ref, in turn, calls mark_our_ref, which checks whether the ref is hidden, and sets OUR_REF or HIDDEN_REF on the object as appropriate. If it is hidden, mark_our_ref also returns "1" to signal send_ref that the ref should not be advertised. If we are not advertising refs, (i.e., the follow-up invocation by an http client to send its "want" lines), we use mark_our_ref directly as a callback to for_each_ref. Its marking does the right thing, but when it then returns "1" to for_each_ref, the latter interprets this as an error and stops iterating. As a result, we skip marking all of the refs that come lexicographically after it. Any "want" lines from the client asking for those objects will fail, as they were not properly marked with OUR_REF. To solve this, we introduce a wrapper callback around mark_our_ref which always returns 0 (even if the ref is hidden, we want to keep iterating). We also tweak the signature of mark_our_ref to exclude unnecessary parameters that were present only to conform to the callback interface. This should make it less likely for somebody to accidentally use it as a callback in the future. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
