Unify RPC code for smart http in protocol v0/v1 and v2, which fixes a bug in the latter (lack of authentication retry) and generally improves the code base. * jt/http-auth-proto-v2-fix: remote-curl: use post_rpc() for protocol v2 also remote-curl: refactor reading into rpc_state's buf remote-curl: reduce scope of rpc_state.result remote-curl: reduce scope of rpc_state.stdin_preamble remote-curl: reduce scope of rpc_state.argv
2019-03-03remote-curl: use post_rpc() for protocol v2 alsoLibravatar Jonathan Tan1-184/+149
When transmitting and receiving POSTs for protocol v0 and v1, remote-curl uses post_rpc() (and associated functions), but when doing the same for protocol v2, it uses a separate set of functions (proxy_rpc() and others). Besides duplication of code, this has caused at least one bug: the auth retry mechanism that was implemented in v0/v1 was not implemented in v2. To fix this issue and avoid it in the future, make remote-curl also use post_rpc() when handling protocol v2. Because line lengths are written to the HTTP request in protocol v2 (unlike in protocol v0/v1), this necessitates changes in post_rpc() and some of the functions it uses; perform these changes too. A test has been included to ensure that the code for both the unchunked and chunked variants of the HTTP request is exercised. Note: stateless_connect() has been updated to use the lower-level packet reading functions instead of struct packet_reader. The low-level control is necessary here because we cannot change the destination buffer of struct packet_reader while it is being used; struct packet_buffer has a peeking mechanism which relies on the destination buffer being present in between a peek and a read.

2019-02-22trace2: create new combined trace facilityLibravatar Jeff Hostetler1-0/+7
Create a new unified tracing facility for git. The eventual intent is to replace the current trace_printf* and trace_performance* routines with a unified set of git_trace2* routines. In addition to the usual printf-style API, trace2 provides higer-level event verbs with fixed-fields allowing structured data to be written. This makes post-processing and analysis easier for external tools. Trace2 defines 3 output targets. These are set using the environment variables "GIT_TR2", "GIT_TR2_PERF", and "GIT_TR2_EVENT". These may be set to "1" or to an absolute pathname (just like the current GIT_TRACE). * GIT_TR2 is intended to be a replacement for GIT_TRACE and logs command summary data. * GIT_TR2_PERF is intended as a replacement for GIT_TRACE_PERFORMANCE. It extends the output with columns for the command process, thread, repo, absolute and relative elapsed times. It reports events for child process start/stop, thread start/stop, and per-thread function nesting. * GIT_TR2_EVENT is a new structured format. It writes event data as a series of JSON records. Calls to trace2 functions log to any of the 3 output targets enabled without the need to call different trace_printf* or trace_performance* routines.

Currently, whenever remote-curl reads pkt-lines from its response file descriptor, only the payload is written to its buf, not the 4 characters denoting the length.

2019-02-06remote-curl: tighten "version 2" check for smart-httpLibravatar Jeff King1-1/+1
In a v2 smart-http conversation, the server should reply to our initial request with a pkt-line saying "version 2". We check that with starts_with(), but really that should be the only thing in that packet. A response of "version 20" should not match. Let's tighten this check to use strcmp(). Note that we don't need to worry about a trailing newline here, because the ptk-line code will have chomped it for us already.

2019-02-06remote-curl: refactor smart-http discoveryLibravatar Jeff King1-43/+57
After making initial contact with an http server, we have to decide if the server supports smart-http, and if so, which version. Our rules are a bit inconsistent: 1. For v0, we require that the content-type indicates a smart-http response. We also require the response to look vaguely like a pkt-line starting with "#". If one of those does not match, we fall back to dumb-http. But according to our http protocol spec[1]: Dumb servers MUST NOT return a return type starting with `application/x-git-`. If we see the expected content-type, we should consider it smart-http. At that point we can parse the pkt-line for real, and complain if it is not syntactically valid. 2. For v2, we do not actually check the content-type. Our v2 protocol spec says[2]: When using the http:// or https:// transport a client makes a "smart" info/refs request as described in `http-protocol.txt`[...] and the http spec is clear that for a smart-http response[3]: The Content-Type MUST be `application/x-$servicename-advertisement`. So it is required according to the spec. These inconsistencies were easy to miss because of the way the original code was written as an inline conditional. Let's pull it out into its own function for readability, and improve a few things: - we now predicate the smart/dumb decision entirely on the presence of the correct content-type - we do a real pkt-line parse before deciding how to proceed (and die if it isn't valid) - use skip_prefix() for comparing service strings, instead of constructing expected output in a strbuf; this avoids dealing with memory cleanup Note that this _is_ tightening what the client will allow. It's all according to the spec, but it's possible that other implementations might violate these. However, violating these particular rules seems like an odd choice for a server to make.

2019-01-02pack-protocol.txt: accept error packets in any contextLibravatar Masaya Suzuki1-3/+6
In the Git pack protocol definition, an error packet may appear only in a certain context. However, servers can face a runtime error (e.g. I/O error) at an arbitrary timing. This patch changes the protocol to allow an error packet to be sent instead of any packet. Without this protocol spec change, when a server cannot process a request, there's no way to tell that to a client. Since the server cannot produce a valid response, it would be forced to cut a connection without telling why. With this protocol spec change, the server can be more gentle in this situation. An old client may see these error packets as an unexpected packet, but this is not worse than having an unexpected EOF. Following this protocol spec change, the error packet handling code is moved to pkt-line.c. Implementation wise, this implementation uses pkt-line to communicate with a subprocess. Since this is not a part of Git protocol, it's possible that a packet that is not supposed to be an error packet is mistakenly parsed as an error packet. This error packet handling is enabled only for the Git pack protocol parsing code considering this.

2018-11-12remote-curl.c: xcurl_off_t is not portable (on 32 bit platfoms)Libravatar Torsten Bögershausen1-3/+4
When setting DEVELOPER = 1 DEVOPTS = extra-all "gcc (Raspbian 6.3.0-18+rpi1+deb9u1) 6.3.0 20170516" errors out with "comparison is always false due to limited range of data type" "[-Werror=type-limits]" It turns out that the function xcurl_off_t() has 2 flavours: - It gives a warning 32 bit systems, like Linux - It takes the signed ssize_t as a paramter, but the only caller is using a size_t (which is typically unsigned these days) The original motivation of this function is to make sure that sizes > 2GiB are handled correctly. The curl documentation says: "For any given platform/compiler curl_off_t must be typedef'ed to a 64-bit wide signed integral data type" On a 32 bit system "size_t" can be promoted into a 64 bit signed value without loss of data, and therefore we may see the "comparison is always false" warning. On a 64 bit system it may happen, at least in theory, that size_t is > 2^63, and then the promotion from an unsigned "size_t" into a signed "curl_off_t" may be a problem. One solution to suppress a possible compiler warning could be to remove the function xcurl_off_t(). However, to be on the very safe side, we keep it and improve it: - The len parameter is changed from ssize_t to size_t - A temporally variable "size" is used, promoted int uintmax_t and the compared with "maximum_signed_value_of_type(curl_off_t)".

2018-05-23remote-curl: accept all encodings supported by curlLibravatar Brandon Williams1-1/+1
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.

2018-03-15remote-curl: don't request v2 when pushingLibravatar Brandon Williams1-1/+10
In order to be able to ship protocol v2 with only supporting fetch, we need clients to not issue a request to use protocol v2 when pushing (since the client currently doesn't know how to push using protocol v2). This allows a client to have protocol v2 configured in `protocol.version` and take advantage of using v2 for fetch and falling back to using v0 when pushing while v2 for push is being designed. We could run into issues if we didn't fall back to protocol v2 when pushing right now. This is because currently a server will ignore a request to use v2 when contacting the 'receive-pack' endpoint and fall back to using v0, but when push v2 is rolled out to servers, the 'receive-pack' endpoint will start responding using v2. So we don't want to get into a state where a client is requesting to push with v2 before they actually know how to push using v2.

2018-02-20remote-curl: unquote incoming push-optionsLibravatar Jeff King1-1/+10
The transport-helper protocol c-style quotes the value of any options passed to the helper via the "option <key> <value>" directive. However, remote-curl doesn't actually unquote the push-option values, meaning that we will send the quoted version to the other side (whereas git-over-ssh would send the raw value). The pack-protocol.txt documentation defines the push-options as a series of VCHARs, which excludes most characters that would need quoting. But: 1. You can still see the bug with a valid push-option that starts with a double-quote (since that triggers quoting). 2. We do currently handle any non-NUL characters correctly in git-over-ssh. So even though the spec does not say that we need to handle most quoted characters, it's nice if our behavior is consistent between protocols. There are two new tests: the "direct" one shows that this already works in the non-http case, and the http one covers this bugfix.

2017-12-05introduce fetch-object: fetch one promisor objectLibravatar Jonathan Tan1-1/+13
Introduce fetch-object, providing the ability to fetch one object from a promisor remote. This uses fetch-pack. To do this, the transport mechanism has been updated with 2 flags, "from-promisor" to indicate that the resulting pack comes from a promisor remote (and thus should be annotated as such by index-pack), and "no-dependents" to indicate that only the objects themselves need to be fetched (but fetching additional objects is nevertheless safe). Whenever "no-dependents" is used, fetch-pack will refrain from using any object flags, because it is most likely invoked as part of a dynamic object fetch by another Git command (which may itself use object flags). An alternative to this is to leave fetch-pack alone, and instead update the allocation of flags so that fetch-pack's flags never overlap with any others, but this will end up shrinking the number of flags available to nearly every other Git command (that is, every Git command that accesses objects), so the approach in this commit was used instead.

This commit was produced mechanically by providing non-Documentation files to the following Perl one-liners: perl -pi -E 's/struct sha1_array/struct oid_array/g' perl -pi -E 's/\bsha1_array_/oid_array_/g' perl -pi -E 's/SHA1_ARRAY_INIT/OID_ARRAY_INIT/g' Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

When the http server gives an incomplete response to a smart-http rpc call, it could lead to client waiting for a full response that will never come. Teach the client side to notice this condition and abort the transfer. An improvement counterproposal has failed. cf. <20161114194049.mktpsvgdhex2f4zv@sigill.intra.peff.net> * dt/smart-http-detect-server-going-away: upload-pack: optionally allow fetching any sha1 remote-curl: don't hang when a server dies before any output
