The recently-introduced "core.alternateRefsCommand" allows callers to specify with high flexibility the tips that they wish to advertise from alternates. This flexibility comes at the cost of some inconvenience when the caller only wishes to limit the advertisement to one or more prefixes. For example, to advertise only tags, a caller using 'core.alternateRefsCommand' would have to do: $ git config core.alternateRefsCommand ' \ f() { git -C "$1" for-each-ref \ refs/tags --format="%(objectname)" }; f "$@"' The above is cumbersome to write, so let's introduce a "core.alternateRefsPrefixes" to address this common case. Instead, the caller can run: $ git config core.alternateRefsPrefixes 'refs/tags' Which will behave identically to the longer example using "core.alternateRefsCommand". Since the value of "core.alternateRefsPrefixes" is appended to 'git for-each-ref' and then executed, include a "--" before taking the configured value to avoid misinterpreting arguments as flags to 'git for-each-ref'. In the case that the caller wishes to specify multiple prefixes, they may separate them by whitespace. If "core.alternateRefsCommand" is set, it will take precedence over "core.alternateRefsPrefixes".

When in a repository containing one or more alternates, Git would sometimes like to list references from those alternates. For example, 'git receive-pack' lists the "tips" pointed to by references in those alternates as special ".have" references. Listing ".have" references is designed to make pushing changes from upstream to a fork a lightweight operation, by advertising to the pusher that the fork already has the objects (via its alternate). Thus, the client can avoid sending them. However, when the alternate (upstream, in the previous example) has a pathologically large number of references, the initial advertisement is too expensive. In fact, it can dominate any such optimization where the pusher avoids sending certain objects. Introduce "core.alternateRefsCommand" in order to provide a facility to limit or filter alternate references. This can be used, for example, to filter out references the alternate does not wish to send (for space concerns, or otherwise) during the initial advertisement. Let the repository that has alternates configure this command to avoid trusting the alternate to provide us a safe command to run in the shell. To find the alternate, pass its absolute path as the first argument.

None of the current callers use the refname parameter we pass to their callbacks. In theory somebody _could_ do so, but it's actually quite weird if you think about it: it's a ref in somebody else's repository. So the name has no meaning locally, and in fact there may be duplicates if there are multiple alternates. The users of this interface really only care about seeing some ref tips, since that promises that the alternate has the full commit graph reachable from there. So let's keep the information we pass back to the bare minimum.

The built-in bundle transport and the transport helper interface do not work when transport_fetch_refs() is called immediately after transport creation. This will be needed in a subsequent patch, so fix this. Evidence: fetch_refs_from_bundle() relies on data->header being initialized in get_refs_from_bundle(), and fetch() in transport-helper.c relies on either data->fetch or data->import being set by get_helper(), but neither transport_helper_init() nor fetch() calls get_helper(). Up until the introduction of the partial clone feature, this has not been a problem, because transport_fetch_refs() is always called after transport_get_remote_refs(). With the introduction of the partial clone feature, which involves calling transport_fetch_refs() (to fetch objects by their OIDs) without transport_get_remote_refs(), this is still not a problem, but only coincidentally - we do not support partially cloning a bundle, and as for cloning using a transport-helper-using protocol, it so happens that before transport_fetch_refs() is called, fetch_refs() in fetch-object.c calls transport_set_option(), which means that the aforementioned get_helper() is invoked through set_helper_option() in transport-helper.c. This could be fixed by fixing the transports themselves, but it doesn't seem like a good idea to me to open up previously untested code paths; also, there may be transport helpers in the wild that assume that "list" is always called before "fetch". Instead, fix this by having transport_fetch_refs() call transport_get_remote_refs() to ensure that the latter is always called at least once, unless the transport explicitly states that it supports fetching without listing refs.

The get_refs_via_connect() function both performs the handshake (including determining the protocol version) and obtaining the list of remote refs.

Using the more restrictive oideq() should, in the long run, give the compiler more opportunities to optimize these callsites. For now, this conversion should be a complete noop with respect to the generated code. The result is also perhaps a little more readable, as it avoids the "zero is equal" idiom. Since it's so prevalent in C, I think seasoned programmers tend not to even notice it anymore, but it can sometimes make for awkward double negations (e.g., we can drop a few !!oidcmp() instances here). This patch was generated almost entirely by the included coccinelle patch. This mechanical conversion should be completely safe, because we check explicitly for cases where oidcmp() is compared to 0, which is what oideq() is doing under the hood. Note that we don't have to catch "!oidcmp()" separately; coccinelle's standard isomorphisms make sure the two are treated equivalently. I say "almost" because I did hand-edit the coccinelle output to fix up a few style violations (it mostly keeps the original formatting, but sometimes unwraps long lines).

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 989b8c44 ("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 989b8c44). 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 989b8c44 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 989b8c44, 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.

During negotiation, fetch-pack eventually reports as "have" lines all commits reachable from all refs. Allow the user to restrict the commits sent in this way by providing a whitelist of tips; only the tips themselves and their ancestors will be sent. Both globs and single objects are supported. This feature is only supported for protocols that support connect or stateless-connect (such as HTTP with protocol v2). This will speed up negotiation when the repository has multiple relatively independent branches (for example, when a repository interacts with multiple repositories, such as with linux-next [1] and torvalds/linux [2]), and the user knows which local branch is likely to have commits in common with the upstream branch they are fetching.

When fetching, connectivity is checked after the shallow file is updated. There are 2 issues with this: (1) the connectivity check is only performed up to ancestors of existing refs (which is not thorough enough if we were deepening an existing ref in the first place), and (2) there is no rollback of the shallow file if the connectivity check fails. To solve (1), update the connectivity check to check the ancestry chain completely in the case of a deepening fetch by refraining from passing "--not --all" when invoking rev-list in connected.c. To solve (2), have fetch_pack() perform its own connectivity check before updating the shallow file. To support existing use cases in which "git fetch-pack" is used to download objects without much regard as to the connectivity of the resulting objects with respect to the existing repository, the connectivity check is only done if necessary (that is, the fetch is not a clone, and the fetch involves shallow/deepen functionality). "git fetch" still performs its own connectivity check, preserving correctness but sometimes performing redundant work. This redundancy is mitigated by the fact that fetch_pack() reports if it has performed a connectivity check itself, and if the transport supports connect or stateless-connect, it will bubble up that report so that "git fetch" knows not to perform the connectivity check in such a case. This was noticed when a user tried to deepen an existing repository by fetching with --no-shallow from a server that did not send all necessary objects - the connectivity check as run by "git fetch" succeeded, but a subsequent "git fsck" failed.

Expand the transport fetch method signature, by adding an output parameter, to allow transports to return information about the refs they have fetched. Then communicate shallow status information through this mechanism instead of by modifying the input list of refs. This does require clients to sometimes generate the ref map twice: once from the list of refs provided by the remote (as is currently done) and potentially once from the new list of refs that the fetch mechanism provides.

When using protocol v2 a client constructs a list of ref-prefixes which are sent across the wire so that the server can do server-side filtering of the ref-advertisement.

In d8193743 (usage.c: add BUG() function, 2017-05-12), a new macro was introduced to use for reporting bugs instead of die().

The cover letter of the patch series containing this patch (cf 20170513032414.mfrwabt4hovujde2@sigill.intra.peff.net) is not terribly clear why only one call site was converted, or what the plan is for other, similar calls to die() to report bugs.

This is an attempt to resolve an issue I experience with people that are new to Git -- especially colleagues in a team setting -- where they miss that their push to a remote location failed because the failure and success both return a block of white text. An example is if I push something to a remote repository and then a colleague attempts to push to the same remote repository and the push fails because it requires them to pull first, but they don't notice because a success and failure both return a block of white text. They then continue about their business, thinking it has been successfully pushed. This patch colorizes the errors and hints (in red and yellow, respectively) so whenever there is a failure when pushing to a remote repository that fails, it is more noticeable.

Introduce the transport-helper capability 'stateless-connect'. This capability indicates that the transport-helper can be requested to run the 'stateless-connect' command which should attempt to make a stateless connection with a remote end. Once established, the connection can be used by the git client to communicate with the remote end natively in a stateless-rpc manner as supported by protocol v2. This means that the client must send everything the server needs in a single request as the client must not assume any state-storing on the part of the server or transport. If a stateless connection cannot be established then the remote-helper will respond in the same manner as the 'connect' command indicating that the client should fallback to using the dumb remote-helper commands. A future patch will implement the 'stateless-connect' capability in our http remote-helper (remote-curl) so that protocol v2 can be used using the http transport.
