2016-09-08Merge branch 'jk/push-force-with-lease-creation' into maintLibravatar Junio C Hamano1-1/+0
"git push --force-with-lease" already had enough logic to allow ensuring that such a push results in creation of a ref (i.e. the receiving end did not have another push from sideways that would be discarded by our force-pushing), but didn't expose this possibility to the users. It does so now. * jk/push-force-with-lease-creation: t5533: make it pass on case-sensitive filesystems push: allow pushing new branches with --force-with-lease push: add shorthand for --force-with-lease branch creation Documentation/git-push: fix placeholder formatting
2016-07-26push: allow pushing new branches with --force-with-leaseLibravatar John Keeping1-1/+0
If there is no upstream information for a branch, it is likely that it is newly created and can safely be pushed under the normal fast-forward rules. Relax the --force-with-lease check so that we do not reject these branches immediately but rather attempt to push them as new branches, using the null SHA-1 as the expected value. In fact, it is already possible to push new branches using the explicit --force-with-lease=<branch>:<expect> syntax, so all we do here is make this behaviour the default if no explicit "expect" value is specified.

2016-02-16remote: simplify remote_is_configured()Libravatar Thomas Gummerer1-1/+2
The remote_is_configured() function allows checking whether a remote exists or not. The function however only works if remote_get() wasn't called before calling it. In addition, it only checks the configuration for remotes, but not remotes or branches files. Make use of the origin member of struct remote instead, which indicates where the remote comes from. It will be set to some value if the remote is configured in any file in the repository, but is initialized to 0 if the remote is only created in make_remote().

2015-05-22remote.c: add branch_get_pushLibravatar Jeff King1-0/+10
In a triangular workflow, the place you pull from and the place you push to may be different. As we have branch_get_upstream for the former, this patch adds branch_get_push for the latter (and as the former implements @{upstream}, so will this implement @{push} in a future patch). Note that the memory-handling for the return value bears some explanation. Some code paths require allocating a new string, and some let us return an existing string. We should provide a consistent interface to the caller, so it knows whether to free the result or not. We could do so by xstrdup-ing any existing strings, and having the caller always free. But that makes us inconsistent with branch_get_upstream, so we would prefer to simply take ownership of the resulting string. We do so by storing it inside the "struct branch", just as we do with the upstream refname (in that case we compute it when the branch is created, but there's no reason not to just fill it in lazily in this case).

2015-05-22remote.c: return upstream name from stat_tracking_infoLibravatar Jeff King1-1/+2
After calling stat_tracking_info, callers often want to print the name of the upstream branch (in addition to the tracking count). To do this, they have to access branch->merge->dst[0] themselves. This is not wrong, as the return value from stat_tracking_info tells us whether we have an upstream branch or not. But it is a bit leaky, as we make an assumption about how it calculated the upstream name. Instead, let's add an out-parameter that lets the caller know the upstream name we found. As a bonus, we can get rid of the unusual tri-state return from the function. We no longer need to use it to differentiate between "no tracking config" and "tracking ref does not exist" (since you can check the upstream_name for that), so we can just use the usual 0/-1 convention for success/error.

2015-05-21remote.c: report specific errors from branch_get_upstreamLibravatar Jeff King1-1/+5
When the previous commit introduced the branch_get_upstream helper, there was one call-site that could not be converted: the one in sha1_name.c, which gives detailed error messages for each possible failure. Let's teach the helper to optionally report these specific errors. This lets us convert another callsite, and means we can use the helper in other locations that want to give the same error messages. The logic and error messages come straight from sha1_name.c, with the exception that we start each error with a lowercase letter, as is our usual style (note that a few tests need updated as a result).

2015-05-21remote.c: provide per-branch pushremote nameLibravatar Jeff King1-0/+2
When remote.c loads its config, it records the branch.*.pushremote for the current branch along with the global remote.pushDefault value, and then binds them into a single value: the default push for the current branch. We then pass this value (which may be NULL) to remote_get_1 when looking up a remote for push. This has a few downsides: 1. It's confusing. The early-binding of the "current value" led to bugs like the one fixed by 98b406f (remote: handle pushremote config in any order, 2014-02-24). And the fact that pushremotes fall back to ordinary remotes is not explicit at all; it happens because remote_get_1 cannot tell the difference between "we are not asking for the push remote" and "there is no push remote configured". 2. It throws away intermediate data. After read_config() finishes, we have no idea what the value of remote.pushDefault was, because the string has been overwritten by the current branch's branch.*.pushremote. 3. It doesn't record other data. We don't note the branch.*.pushremote value for anything but the current branch. Let's make this more like the fetch-remote config. We'll record the pushremote for each branch, and then explicitly compute the correct remote for the current branch at the time of reading.

2015-05-21remote.c: hoist branch.*.remote lookup out of remote_get_1Libravatar Jeff King1-0/+1
We'll want to use this logic as a fallback when looking up the pushremote, so let's pull it out into its own function. We don't technically need to make this available outside of remote.c, but doing so will provide a consistent API with pushremote_for_branch, which we will add later.

2015-05-21remote.c: drop "remote" pointer from "struct branch"Libravatar Jeff King1-1/+0
When we create each branch struct, we fill in the "remote_name" field from the config, and then fill in the actual "remote" field (with a "struct remote") based on that name. However, it turns out that nobody really cares about the latter field. The only two sites that access it at all are: 1. git-merge, which uses it to notice when the branch does not have a remote defined. But we can easily replace this with looking at remote_name instead. 2. remote.c itself, when setting up the @{upstream} merge config. But we don't need to save the "remote" in the "struct branch" for that; we can just look it up for the duration of the operation. So there is no need to have both fields; they are redundant with each other (the struct remote contains the name, or you can look up the struct from the name). It would be nice to simplify this, especially as we are going to add matching pushremote config in a future patch (and it would be nice to keep them consistent). So which one do we keep and which one do we get rid of? If we had a lot of callers accessing the struct, it would be more efficient to keep it (since you have to do a lookup to go from the name to the struct, but not vice versa). But we don't have a lot of callers; we have exactly one, so efficiency doesn't matter. We can decide this based on simplicity and readability. And the meaning of the struct value is somewhat unclear. Is it always the remote matching remote_name? If remote_name is NULL (i.e., no per-branch config), does the struct fall back to the "origin" remote, or is it also NULL? These questions will get even more tricky with pushremotes, whose fallback behavior is more complicated. So let's just store the name, which pretty clearly represents the branch.*.remote config. Any lookup or fallback behavior can then be implemented in helper functions. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2015-01-07send-pack.c: add --atomic command line argumentLibravatar Ronnie Sahlberg1-1/+2
This adds support to send-pack to negotiate and use atomic pushes iff the server supports it. Atomic pushes are activated by a new command line flag --atomic. In order to do this we also need to change the semantics for send_pack() slightly. The existing send_pack() function actually doesn't send all the refs back to the server when multiple refs are involved, for example when using --all. Several of the failure modes for pushes can already be detected locally in the send_pack client based on the information from the initial server side list of all the refs as generated by receive-pack. Any such refs that we thus know would fail to push are thus pruned from the list of refs we send to the server to update. For atomic pushes, we have to deal thus with both failures that are detected locally as well as failures that are reported back from the server. In order to do so we treat all local failures as push failures too. We introduce a new status code REF_STATUS_ATOMIC_PUSH_FAILED so we can flag all refs that we would normally have tried to push to the server but we did not due to local failures. This is to improve the error message back to the end user to flag that "these refs failed to update since the atomic push operation failed."

2014-07-30use a hashmap to make remotes fasterLibravatar Patrick Reynolds1-0/+3
Remotes are stored as an array, so looking one up or adding one without duplication is an O(n) operation. Reading an entire config file full of remotes is O(n^2) in the number of remotes. For a repository with tens of thousands of remotes, the running time can hit multiple minutes. Hash tables are way faster. So we add a hashmap from remote name to struct remote and use it for all lookups. The time to add a new remote to a repo that already has 50,000 remotes drops from ~2 minutes to < 1 second. We retain the old array of remotes so iterators proceed in config-file order.

2014-03-05push: detect local refspec errors earlyLibravatar Jeff King1-0/+1
When pushing, we do not even look at our push refspecs until after we have made contact with the remote receive-pack and gotten its list of refs. This means that we may go to some work, including asking the user to log in, before realizing we have simple errors like "git push origin matser". We cannot catch all refspec problems, since fully evaluating the refspecs requires knowing what the remote side has. But we can do a quick sanity check of the local side and catch a few simple error cases. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This patch just put together pieces from the 8 steps patch. We stop at step 7 and reject refs that require new shallow commits. Note that, by rejecting refs that require new shallow commits, we leave dangling objects in the repo, which become "object islands" by the next "git fetch" of the same source.

2013-12-04push: use remote.$name.push as a refmapLibravatar Junio C Hamano1-0/+2
Since f2690487 (fetch: opportunistically update tracking refs, 2013-05-11), we stopped taking a non-storing refspec given on the command line of "git fetch" literally, and instead started mapping it via remote.$name.fetch refspecs. This allows $ git fetch origin master from the 'origin' repository, which is configured with [remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* to update refs/remotes/origin/master with the result, as if the command line were $ git fetch origin +master:refs/remotes/origin/master to reduce surprises and improve usability. Before that change, a refspec on the command line without a colon was only to fetch the history and leave the result in FETCH_HEAD, without updating the remote-tracking branches. When you are simulating a fetch from you by your mothership with a push by you into your mothership, instead of having: [remote "satellite"] fetch = +refs/heads/*:refs/remotes/satellite/* on the mothership repository and running: mothership$ git fetch satellite you would have: [remote "mothership"] push = +refs/heads/*:refs/remotes/satellite/* on your satellite machine, and run: satellite$ git push mothership Because we so far did not make the corresponding change to the push side, this command: satellite$ git push mothership master does _not_ allow you on the satellite to only push 'master' out but still to the usual destination (i.e. refs/remotes/satellite/master). Implement the logic to map an unqualified refspec given on the command line via the remote.$name.push refspec. This will bring a bit more symmetry between "fetch" and "push".

Allow a safer "rewind of the remote tip" push than blind "--force", by requiring that the overwritten remote ref to be unchanged since the new history to replace it was prepared. The machinery is more or less ready. The "--force" option is again the big red button to override any safety, thanks to J6t's sanity (the original round allowed --lockref to defeat --force). The logic to choose the default implemented here is fragile (e.g. "git fetch" after seeing a failure will update the remote-tracking branch and will make the next "push" pass, defeating the safety pretty easily).

This plugs the push_cas_option data collected by the command line option parser to the transport system with a new function apply_push_cas(), which is called after match_push_refs() has already been called. At this point, we know which remote we are talking to, and what remote refs we are going to update, so we can fill in the details that may have been missing from the command line, such as (1) what abbreviated refname the user gave us matches the actual refname at the remote; and (2) which remote-tracking branch in our local repository to read the value of the object to expect at the remote. to populate the old_sha1_expect[] field of each of the remote ref.

2013-07-22remote.c: add command line option parser for "--force-with-lease"Libravatar Junio C Hamano1-0/+22
Update "git push" and "git send-pack" to parse this commnd line option. The intended sematics is: * "--force-with-lease" alone, without specifying the details, will protect _all_ remote refs that are going to be updated by requiring their current value to be the same as some reasonable default, unless otherwise specified; * "--force-with-lease=refname", without specifying the expected value, will protect that refname, if it is going to be updated, by requiring its current value to be the same as some reasonable default. * "--force-with-lease=refname:value" will protect that refname, if it is going to be updated, by requiring its current value to be the same as the specified value; and * "--no-force-with-lease" will cancel all the previous --force-with-lease on the command line. For now, "some reasonable default" is tentatively defined as "the value of the remote-tracking branch we have for the ref of the remote being updated", and it is an error if we do not have such a remote-tracking branch. But this is known to be fragile, its use is not yet recommended, and hopefully we will find more reasonable default as we gain experience with this feature. The manual marks the feature as experimental unless the expected value is specified explicitly for this reason. Because the command line options are parsed _before_ we know which remote we are pushing to, there needs further processing to the parsed data after we instantiate the transport object to: * expand "refname" given by the user to a full refname to be matched with the list of "struct ref" used in match_push_refs() and set_ref_status_for_push(); and * learning the actual local ref that is the remote-tracking branch for the specified remote ref. Further, some processing need to be deferred until we find the set of remote refs and match_push_refs() returns in order to find the ones that need to be checked after explicit ones have been processed for "--force-with-lease" (no specific details). These post-processing will be the topic of the next patch. This option was originally called "cas" (for "compare and swap"), the name which nobody liked because it was too technical. The second attempt called it "lockref" (because it is conceptually like pushing after taking a lock) but the word "lock" was hated because it implied that it may reject push by others, which is not the way this option works. This round calls it "force-with-lease". You assume you took the lease on the ref when you fetched to decide what the rebased history should be, and you can push back only if the lease has not been broken.

2013-07-18fetch: make --prune configurableLibravatar Michael Schubert1-0/+1
Without "git fetch --prune", remote-tracking branches for a branch the other side already has removed will stay forever. Some people want to always run "git fetch --prune". To accommodate users who want to either prune always or when fetching from a particular remote, add two new configuration variables "fetch.prune" and "remote.<name>.prune": - "fetch.prune" allows to enable prune for all fetch operations. - "remote.<name>.prune" allows to change the behaviour per remote. The latter will naturally override the former, and the --[no-]prune option from the command line will override the configured default. Since --prune is a potentially destructive operation (Git doesn't keep reflogs for deleted references yet), we don't want to prune without users consent, so this configuration will not be on by default.

2013-04-02remote.c: introduce a way to have different remotes for fetch/pushLibravatar Ramkumar Ramachandra1-0/+1
Currently, do_push() in push.c calls remote_get(), which gets the configured remote for fetching and pushing. Replace this call with a call to pushremote_get() instead, a new function that will return the remote configured specifically for pushing. This function tries to work with the string pushremote_name, before falling back to the codepath of remote_get(). This patch has no visible impact, but serves to enable future patches to introduce configuration variables to set pushremote_name. For example, you can now do the following in handle_config(): if (!strcmp(key, "remote.pushdefault")) git_config_string(&pushremote_name, key, value); Then, pushes will automatically go to the remote specified by remote.pushdefault.

With this change, running this command $ git push --prune remote refs/heads/*:refs/remotes/laptop/* removes refs/remotes/laptop/foo from the remote if we do not have branch "foo" locally anymore.

2011-10-15fetch: honor the user-provided refspecs when pruning refsLibravatar Carlos Martín Nieto1-1/+1
If the user gave us refspecs on the command line, we should use those when deciding whether to prune a ref instead of relying on the refspecs in the config. Previously, running git fetch --prune origin refs/heads/master:refs/remotes/origin/master would delete every other ref under the origin namespace because we were using the refspec to filter the available refs but using the configured refspec to figure out if a ref had been deleted on the remote. This is clearly the wrong thing to do. Change prune_refs and get_stale_heads to simply accept a list of references and a list of refspecs. The caller of either function needs to decide what refspecs should be used to decide whether a ref is stale.

2011-09-12rename "match_refs()" to "match_push_refs()"Libravatar Junio C Hamano1-2/+2
Yes, there is a warning that says the function is only used by push in big red letters in front of this function, but it didn't say a more important thing it should have said: what the function is for and what it does. Rename it and document it to avoid future confusion. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-05-31enums: omit trailing comma for portabilityLibravatar Gary V. Vaughan1-1/+1
Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX 5.1 fails to compile git. enum style is inconsistent already, with some enums declared on one line, some over 3 lines with the enum values all on the middle line, sometimes with 1 enum value per line... and independently of that the trailing comma is sometimes present and other times absent, often mixing with/without trailing comma styles in a single file, and sometimes in consecutive enum declarations. Clearly, omitting the comma is the more portable style, and this patch changes all enum declarations to use the portable omitted dangling comma style consistently. Signed-off-by: Gary V.

2010-01-09refactor ref status logic for pushingLibravatar Tay Ray Chuan1-0/+2
Move the logic that detects up-to-date and non-fast-forward refs to a new function in remote.[ch], set_ref_status_for_push(). Make transport_push() invoke set_ref_status_for_push() before invoking the push_refs() implementation. (As a side-effect, the push_refs() implementation in transport-helper.c now knows of non-fast-forward pushes.) Removed logic for detecting up-to-date refs from the push_refs() implementation in transport-helper.c, as transport_push() has already done so for it. Make cmd_send_pack() invoke set_ref_status_for_push() before invoking send_pack(), as transport_push() can't do it for send_pack() here. Mark the test on the return status of non-fast-forward push to fail. Git now exits with success, as transport.c::transport_push() does not check for refs with status REF_STATUS_REJECT_NONFASTFORWARD nor does it indicate rejected pushes with its return value. Mark the test for ref status to succeed. As mentioned earlier, refs might be marked as non-fast-forwards, triggering the push status printing mechanism in transport.c.

2009-11-17Allow helper to map private ref names into normal namesLibravatar Daniel Barkalow1-0/+5
This allows a helper to say that, when it handles "import refs/heads/topic", the script it outputs will actually write to refs/svn/origin/branches/topic; therefore, transport-helper should read it from the latter location after git-fast-import completes.

2009-11-17Add a config option for remotes to specify a foreign vcsLibravatar Daniel Barkalow1-0/+2
If this is set, the url is not required, and the transport always uses a helper named "git-remote-<value>". It is a separate configuration option in order to allow a sensible configuration for foreign systems which either have no meaningful urls for repositories or which require urls that do not specify the system used by the repository at that location. However, this only affects how the name of the helper is determined, not anything about the interaction with the helper, and the contruction is such that, if the foreign scm does happen to use a co-named url method, a url with that method may be used directly.

This introduces a config setting remote.$remotename.pushurl which is used for pushes only. If absent remote.$remotename.url is used for pushes and fetches as before. This is useful, for example, in order to do passwordless fetches (remote update) over the git transport but pushes over ssh.
