Commit 1bbcc224 ("http: refactor options to http_get_*", 28-09-2013) changed the type of final 'options' argument of the http_get_file() function from an int to an 'struct http_get_options' pointer. However, it neglected to update the (single) call site. Since this call was passing '0' to that argument, it was (correctly) being interpreted as a null pointer. Change to argument to NULL. Noticed by sparse.

If a caller asks the http_get_* functions to go to a particular URL and we end up elsewhere due to a redirect, the effective_url field can tell us where we went. It would be nice to remember this redirect and short-cut further requests for two reasons: 1. It's more efficient. Otherwise we spend an extra http round-trip to the server for each subsequent request, just to get redirected. 2. If we end up with an http 401 and are going to ask for credentials, it is to feed them to the redirect target. If the redirect is an http->https upgrade, this means our credentials may be provided on the http leg, just to end up redirected to https. And if the redirect crosses server boundaries, then curl will drop the credentials entirely as it follows the redirect. However, it, it is not enough to simply record the effective URL we saw and use that for subsequent requests. We were originally fed a "base" url like: http://example.com/foo.git and we want to figure out what the new base is, even though the URLs we see may be: original: http://example.com/foo.git/info/refs effective: http://example.com/bar.git/info/refs Subsequent requests will not be for "info/refs", but for other paths relative to the base. We must ask the caller to pass in the original base, and we must pass the redirected base back to the caller (so that it can generate more URLs from it). Furthermore, we need to feed the new base to the credential code, so that requests to credential helpers (or to the user) match the URL we will be requesting. This patch teaches http_request_reauth to do this munging. Since it is the caller who cares about making more URLs, it seems at first glance that callers could simply check effective_url themselves and handle it. However, since we need to update the credential struct before the second re-auth request, we have to do it inside http_request_reauth.

When we ask curl to access a URL, it may follow one or more redirects to reach the final location. We have no idea this has happened, as curl takes care of the details and simply returns the final content to us. The final URL that we ended up with can be accessed via CURLINFO_EFFECTIVE_URL. Let's make that optionally available to callers of http_get_*, so that they can make further decisions based on the redirection.

When we are handling a curl response code in http_request or in the remote-curl RPC code, we use the handle_curl_result helper to translate curl's response into an easy-to-use code. When we see an HTTP 401, we do one of two things: 1. If we already had a filled-in credential, we mark it as rejected, and then return HTTP_NOAUTH to indicate to the caller that we failed. 2. If we didn't, then we ask for a new credential and tell the caller HTTP_REAUTH to indicate that they may want to try again. Rejecting in the first case makes sense; it is the natural result of the request we just made. However, prompting for more credentials in the second step does not always make sense. We do not know for sure that the caller is going to make a second request, and nor are we sure that it will be to the same URL. Logically, the prompt belongs not to the request we just finished, but to the request we are (maybe) about to make. In practice, it is very hard to trigger any bad behavior. Currently, if we make a second request, it will always be to the same URL (even in the face of redirects, because curl handles the redirects internally). And we almost always retry on HTTP_REAUTH these days. The one exception is if we are streaming a large RPC request to the server (e.g., a pushed packfile), in which case we cannot restart. It's extremely unlikely to see a 401 response at this stage, though, as we would typically have seen it when we sent a probe request, before streaming the data. This patch drops the automatic prompt out of case 2, and instead requires the caller to do it. This is a few extra lines of code, and the bug it fixes is unlikely to come up in practice. But it is conceptually cleaner, and paves the way for better handling of credentials across redirects. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJonathan Nieder <jrnieder@gmail.com>

Over time, the http_get_strbuf function has grown several optional parameters. We now have a bitfield with multiple boolean options, as well as an optional strbuf for returning the content-type of the response. And a future patch in this series is going to add another strbuf option. Treating these as separate arguments has a few downsides: 1. Most call sites need to add extra NULLs and 0s for the options they aren't interested in. 2. The http_get_* functions are actually wrappers around 2 layers of low-level implementation functions. We have to pass these options through individually. 3. The http_get_strbuf wrapper learned these options, but nobody bothered to do so for http_get_file, even though it is backed by the same function that does understand the options. Let's consolidate the options into a single struct. For the common case of the default options, we'll allow callers to simply pass a NULL for the options struct. The resulting code is often a few lines longer, but it ends up being easier to read (and to change as we add new options, since we do not need to update each call site).

Curl older than 7.17 (RHEL 4.X provides 7.12 and RHEL 5.X provides 7.15) requires that we manage any strings that we pass to it as pointers. So, we really shouldn't be modifying this strbuf after we have passed it to curl. Our interaction with curl is currently safe (before or after this patch) since the pointer that is passed to curl is never invalidated; it is repeatedly rewritten with the same sequence of characters but the strbuf functions never need to allocate a larger string, so the same memory buffer is reused. This "guarantee" of safety is somewhat subtle and could be overlooked by someone who may want to add a more complex handling of the username and password. So, let's stop modifying this strbuf after we have passed it to curl, but also leave a note to describe the assumptions that have been made about username/password lifetime and to draw attention to the code.

Because we reuse curl handles for multiple requests, the setup of a handle happens in two stages: stable, global setup and per-request setup. The lifecycle of a handle is something like: 1. get_curl_handle; do basic global setup that will last through the whole program (e.g., setting the user agent, ssl options, etc) 2. get_active_slot; set up a per-request baseline (e.g., clearing the read/write functions, making it a GET request, etc) 3. perform the request with curl_*_perform functions 4. goto step 2 to perform another request Breaking it down this way means we can avoid doing global setup from step (1) repeatedly, but we still finish step (2) with a predictable baseline setup that callers can rely on. Until commit 6d052d78 (http: add HTTP_KEEP_ERROR option, 2013-04-05), setting curl's FAILONERROR option was a global setup; we never changed it. However, 6d052d78 introduced an option where some requests might turn off FAILONERROR. Later requests using the same handle would have the option unexpectedly turned off, which meant they would not notice http failures at all. This could easily be seen in the test-suite for the "half-auth" cases of t5541 and t5551. The initial requests turned off FAILONERROR, which meant it was erroneously off for the rpc POST. That worked fine for a successful request, but meant that we failed to react properly to the HTTP 401 (instead, we treated whatever the server handed us as a successful message body). The solution is simple: now that FAILONERROR is a per-request setting, we move it to get_active_slot to make sure it is reset for each request.

When we report an http error code, we say something like: error: The requested URL reported failure: 403 Forbidden while accessing http://example.com/repo.git Everything between "error:" and "while" is written by curl, and the resulting sentence is hard to read (especially because there is no punctuation between curl's sentence and the remainder of ours).

This helper function should really be a one-liner that prints an error message, but it has ended up unnecessarily complicated: 1. We call error() directly when we fail to start the curl request, so we must later avoid printing a duplicate error in http_error(). It would be much simpler in this case to just stuff the error message into our usual curl_errorstr buffer rather than printing it ourselves. This means that http_error does not even have to care about curl's exit value (the interesting part is in the errorstr buffer already). 2. We return the "ret" value passed in to us, but none of the callers actually cares about our return value. We can just drop this entirely.

It has been observed that curl_multi_timeout may return a very long timeout value (e.g., 294 seconds and some usec) just before curl_multi_fdset returns no file descriptors for reading. The upshot is that select() will hang for a long time -- long enough for an https handshake to be dropped. The observed behavior is that the git command will hang at the terminal and never transfer any data. This patch is a workaround for a probable bug in libcurl. The bug only seems to manifest around a very specific set of circumstances: - curl version (from curl/curlver.h): #define LIBCURL_VERSION_NUM 0x071307 - git-remote-https running on an ubuntu-lucid VM. - Connecting through squid proxy running on another VM. Interestingly, the problem doesn't manifest if a host connects through squid proxy running on localhost; only if the proxy is on a separate VM (not sure if the squid host needs to be on a separate physical machine). That would seem to suggest that this issue is timing-sensitive. This patch is more or less in line with a recommendation in the curl docs about how to behave when curl_multi_fdset doesn't return and file descriptors: http://curl.haxx.se/libcurl/c/curl_multi_fdset.htmlSigned-off-by: NStefan Zager <szager@google.com> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

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 42653c09, this was a necessary step. However, since dfa1725a, 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.

When we create an http active_request_slot, we can set its "results" pointer back to local storage. 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 88097030 (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).

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: NShawn O.

We give the username and password to curl by sticking them in a buffer of the form "user:pass" and handing the result to CURLOPT_USERPWD. Since curl 7.19.1, there is a split mechanism, where you can specify each element individually. This has the advantage that a username can contain a ":" character. It also is less code for us, since we can hand our strings over to curl directly. And since curl 7.17.0 and higher promise to copy the strings for us, we we don't even have to worry about memory ownership issues. Unfortunately, we have to keep the ugly code for old curl around, but as it is now nicely #if'd out, we can easily get rid of it when we decide that 7.19.1 is "old enough".

When we have a credential to give to curl, we must copy it into a "user:pass" buffer and then hand the buffer to curl. Old versions of curl did not copy the buffer, and we were expected to keep it valid. Newer versions of curl will copy the buffer. Our solution was to use a strbuf and detach it, giving ownership of the resulting buffer to curl. However, this meant that we were leaking the buffer on newer versions of curl, since curl was just copying it and throwing away the string we passed. Furthermore, when we replaced a credential (e.g., because our original one was rejected), we were also leaking on both old and new versions of curl. This got even worse in the last patch, which started replacing the credential (and thus leaking) on every http request. Instead, let's use a static buffer to make the ownership more clear and less leaky. We already keep a static "struct credential", so we are only handling a single credential at a time, anyway.

HTTP authentication is currently handled by get_refs and fetch_ref, but not by fetch_object, fetch_pack or fetch_alternates. In the single-threaded case, this is not an issue, since get_refs is always called first. It recognigzes the 401 and prompts the user for credentials, which will then be used subsequently. If the curl multi interface is used, however, only the multi handle used by get_refs will have credentials configured. Requests made by other handles fail with an authentication error.

When the proxy server specified by the http.proxy configuration or the http_proxy environment variable requires authentication, git failed to connect to the proxy, because we did not configure the cURL handle with CURLOPT_PROXYAUTH. When a proxy is in use, and you tell git that the proxy requires authentication by having username in the http.proxy configuration, an extra request needs to be made to the proxy to find out what authentication method it supports, as this patch uses CURLAUTH_ANY to let the library pick the most secure method supported by the proxy server. The extra round-trip adds extra latency, but relieves the user from the burden to configure a specific authentication method. If it becomes problem, a later patch could add a configuration option to specify what method to use, but let's start simple for the time being.

Before commit 986bbc08, git was proactive about asking for http passwords. 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 patch does a quick fix of re-enabling the "proactive auth" strategy only for http-push, leaving the dumb http fetch and smart-http as-is.

This patch converts the http code to use the new credential API, both for http authentication as well as for getting certificate passwords. Most of the code change is simply variable naming (the passwords are now contained inside the credential struct) or deletion of obsolete code (the credential code handles URL parsing and prompting for us). The behavior should be the same, with one exception: the credential code will prompt with a description based on the credential components. Therefore, the old prompt of: Username for 'example.com': Password for 'example.com': now looks like: Username for 'https://example.com/repo.git': Password for 'https://user@example.com/repo.git': Note that we include more information in each line, specifically: 1. We now include the protocol. While more noisy, this is an important part of knowing what you are accessing (especially if you care about http vs https). 2. We include the username in the password prompt. This is not a big deal when you have just been prompted for it, but the username may also come from the remote's URL (and after future patches, from configuration or credential helpers). In that case, it's a nice reminder of the user for which you're giving the password. 3. We include the path component of the URL. In many cases, the user won't care about this and it's simply noise (i.e., they'll use the same credential for a whole site). However, that is part of a larger question, which is whether path components should be part of credential context, both for prompting and for lookup by storage helpers. That issue will be addressed as a whole in a future patch. Similarly, for unlocking certificates, we used to say: Certificate Password for 'example.com': and we now say: Password for 'cert:///path/to/certificate': Showing the path to the client certificate makes more sense, as that is what you are unlocking, not "example.com".

Recent versions of curl can suggest a period of time the library user should sleep and try again, when curl is blocked on reading or writing (or connecting). Use this timeout instead of always sleeping for 50ms.

Instead of sleeping unconditionally for a 50ms, when no data can be read from the http connection(s), use curl_multi_fdset() to obtain the actual file descriptors of the open connections and use them in the select call. This way, the 50ms sleep is interrupted when new data arrives.

When a username is already specified at the beginning of any HTTP transaction (e.g. "git push https://user@hosting.example.com/project.git" or "git ls-remote https://user@hosting.example.com/project.git"), the code interactively asks for a password before calling into the libcurl library. It is very likely that the reason why user included the username in the URL is because the user knows that it would require authentication to access the resource. Asking for the password upfront would save one roundtrip to get a 401 response, getting the password and then retrying the request. This is a reasonable optimization. HOWEVER. This is done even when $HOME/.netrc might have a corresponding entry to access the site, or the site does not require authentication to access the resource after all. But neither condition can be determined until we call into libcurl library (we do not read and parse $HOME/.netrc ourselves). In these cases, the user is forced to respond to the password prompt, only to give a password that is not used in the HTTP transaction. If the password is in $HOME/.netrc, an empty input would later let the libcurl layer to pick up the password from there, and if the resource does not require authentication, any input would be taken and then discarded without getting used. It is wasteful to ask this unused information to the end user. Reduce the confusion by not trying to optimize for this case and always incur roundtrip penalty. An alternative might be to document this and keep this round-trip optimization as-is.

The http_init function takes a "struct remote". Part of its initialization procedure is to look at the remote's url and grab some auth-related parameters. However, using the url included in the remote is: - wrong; the remote-curl helper may have a separate, unrelated URL (e.g., from remote.*.pushurl). Looking at the remote's configured url is incorrect. - incomplete; http-fetch doesn't have a remote, so passes NULL. So http_init never gets to see the URL we are actually going to use. - cumbersome; http-push has a similar problem to http-fetch, but actually builds a fake remote just to pass in the URL. Instead, let's just add a separate URL parameter to http_init, and all three callsites can pass in the appropriate information.
