2017-04-11push: propagate remote and refspec with --recurse-submodulesLibravatar Brandon Williams1-1/+2
Teach "push --recurse-submodules" to propagate, if given a name as remote, the provided remote and refspec recursively to the pushes performed in the submodules. The push will therefore only succeed if all submodules have a remote with such a name configured. Note that "push --recurse-submodules" with a path or URL as remote will not propagate the remote or refspec and instead use the default remote and refspec configured in the submodule, preserving the current behavior.

2017-03-26Convert GIT_SHA1_HEXSZ used for allocation to GIT_MAX_HEXSZLibravatar brian m. carlson1-1/+1
Since we will likely be introducing a new hash function at some point, and that hash function might be longer than 40 hex characters, use the constant GIT_MAX_HEXSZ, which is designed to be suitable for allocations, instead of GIT_SHA1_HEXSZ. This will ease the transition down the line by distinguishing between places where we need to allocate memory suitable for the largest hash from those where we need to handle the current hash.

"git fetch" currently doesn't bother to check that it got all refs it sought, because the common case of requesting a nonexistent ref triggers a die() in get_fetch_map. However, there's at least one case that slipped through: "git fetch REMOTE SHA1" if the server doesn't allow requests for unadvertised objects. Make fetch_refs_via_pack (which is on the "git fetch" code path) call report_unmatched_refs so that we at least get an error message in that case.

2017-02-20delete_ref: accept a reflog message argumentLibravatar Kyle Meyer1-1/+1
When the current branch is renamed with 'git branch -m/-M' or deleted with 'git update-ref -m<msg> -d', the event is recorded in HEAD's log with an empty message. In preparation for adding a more meaningful message to HEAD's log in these cases, update delete_ref() to take a message argument and pass it along to ref_transaction_delete(). Modify all callers to pass NULL for the new message argument; no change in behavior is intended. Note that this is relevant for HEAD's log but not for the deleted ref's log, which is currently deleted along with the ref. Even if it were not, an entry for the deletion wouldn't be present in the deleted ref's log. files_transaction_commit() writes to the log if REF_NEEDS_COMMIT or REF_LOG_ONLY are set, but lock_ref_for_update() doesn't set REF_NEEDS_COMMIT for the deleted ref because REF_DELETING is set. In contrast, the update for HEAD has REF_LOG_ONLY set by split_head_update(), resulting in the deletion being logged.

2017-02-08for_each_alternate_ref: replace transport code with for-each-refLibravatar Jeff King1-10/+38
The current method for getting the refs from an alternate is to run upload-pack in the alternate and parse its output using the normal transport code. This works and is reasonably short, but it has a very bad memory footprint when there are a lot of refs in the alternate. There are two problems: 1. It reads in all of the refs before passing any back to us. Which means that our peak memory usage has to store every ref (including duplicates for peeled variants), even if our callback could determine that some are not interesting (e.g., because they point to the same sha1 as another ref). 2. It allocates a "struct ref" for each one. Among other things, this contains 3 separate 20-byte oids, along with the name and various pointers. That can add up, especially if the callback is only interested in the sha1 (which it can store in a sha1_array as just 20 bytes). On a particularly pathological case, where the alternate had over 80 million refs pointing to only around 60,000 unique objects, the peak heap usage of "git clone --reference" grew to over 25GB. This patch instead calls git-for-each-ref in the alternate repository, and passes each line to the callback as we read it. That drops the peak heap of the same command to 50MB. I considered and rejected a few alternatives. We could read all of the refs in the alternate using our own ref code, just as we do with submodules. However, as memory footprint is one of the concerns here, we want to avoid loading those refs into our own memory as a whole. It's possible that this will be a better technique in the future when the ref code can more easily iterate without loading all of packed-refs into memory. Another option is to keep calling upload-pack, and just parse its output ourselves in a streaming fashion. Besides for-each-ref being simpler (we get to define the format ourselves, and don't have to deal with speaking the git protocol), it's more flexible for possible future changes. For instance, it might be useful for the caller to be able to limit the set of "interesting" alternate refs. The motivating example is one where many "forks" of a particular repository share object storage, and the shared storage has refs for each fork (which is why so many of the refs are duplicates; each fork has the same tags). A plausible future optimization would be to ask for the alternate refs for just _one_ fork (if you had some out-of-band way of knowing which was the most interesting or important for the current operation). Similarly, no callbacks actually care about the symref value of alternate refs, and as before, this patch ignores them entirely. However, if we wanted to add them, for-each-ref's "%(symref)" is going to be more flexible than upload-pack, because the latter only handles the HEAD symref due to historical constraints. There is one potential downside, though: unlike upload-pack, our for-each-ref command doesn't report the peeled value of refs. The existing code calls the alternate_ref_fn callback twice for tags: once for the tag, and once for the peeled value with the refname set to "ref^{}". For the callers in fetch-pack, this doesn't matter at all. We immediately peel each tag down to a commit either way (so there's a slight improvement, as do not bother passing the redundant data over the pipe). For the caller in receive-pack, it means we will not advertise the peeled values of tags in our alternate. However, we also don't advertise peeled values for our _own_ tags, so this is actually making things more consistent. It's unclear whether receive-pack advertising peeled values is a win or not. On one hand, giving more information to the other side may let it omit some objects from the push. On the other hand, for tags which both sides have, they simply bloat the advertisement. The upload-pack advertisement of git.git is about 30% larger than the receive-pack advertisement due to its peeled information. This patch omits the peeled information from for_each_alternate_ref entirely, and leaves it up to the caller whether they want to dig up the information.

2017-02-08for_each_alternate_ref: use strbuf for path allocationLibravatar Jeff King1-14/+14
We have a string with ".../objects" pointing to the alternate object store, and overwrite bits of it to look at other paths in the (potential) git repository holding it. This works because the only path we care about is "refs", which is shorter than "objects". Using a strbuf to hold the path lets us get rid of some magic numbers, and makes it more obvious that the memory operations are safe.

2017-02-08for_each_alternate_ref: stop trimming trailing slashesLibravatar Jeff King1-2/+0
The real_pathdup() function will have removed extra slashes for us already (on top of the normalize_path() done when we created the alternate_object_database struct in the first place). Incidentally, this also fixes the case where the path is just "/", which would read off the start of the array. That doesn't seem possible to trigger in practice, though, as link_alt_odb_entry() blindly eats trailing slashes, including a bare "/".

2017-02-08for_each_alternate_ref: handle failure from real_pathdup()Libravatar Jeff King1-0/+2
In older versions of git, if real_path() failed to resolve the alternate object store path, we would die() with an error. However, since 4ac9006f8 (real_path: have callers use real_pathdup and strbuf_realpath, 2016-12-12) we use the real_pathdup() function, which may return NULL. Since we don't check the return value, we can segfault. This is hard to trigger in practice, since we check that the path is accessible before creating the alternate_object_database struct. But it could be removed racily, or we could see a transient filesystem error. We could restore the original behavior by switching back to xstrdup(real_path()). However, dying is probably not the best option here. This whole function is best-effort already; there might not even be a repository around the shared objects at all. And if the alternate store has gone away, there are no objects to show. So let's just quietly return, as we would if we failed to open "refs/", or if upload-pack failed to start, etc. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-12-20push: add option to push only submodulesLibravatar Brandon Williams1-4/+11
Teach push the --recurse-submodules=only option. This enables push to recursively push all unpushed submodules while leaving the superproject unpushed. This is a desirable feature in a scenario where updates to the superproject are handled automatically by some other means, perhaps a tool like Gerrit code review. In this scenario, a developer could make a change which spans multiple submodules and then push their commits for code review. Upon completion of the code review, their commits can be accepted and applied to their respective submodules while the code review tool can then automatically update the superproject to the most recent SHA1 of each submodule. This would reduce the merge conflicts in the superproject that could occur if multiple people are contributing to the same submodule.

2016-12-15transport: add from_user parameter to is_transport_allowedLibravatar Brandon Williams1-3/+5
Add a from_user parameter to is_transport_allowed() to allow http to be able to distinguish between protocol restrictions for redirects versus initial requests. CURLOPT_REDIR_PROTOCOLS can now be set differently from CURLOPT_PROTOCOLS to disallow use of protocols with the "user" policy in redirects. This change allows callers to query if a transport protocol is allowed, given that the caller knows that the protocol is coming from the user (1) or not from the user (0) such as redirects in libcurl. If unknown a -1 should be provided which falls back to reading `GIT_PROTOCOL_FROM_USER` to determine if the protocol came from the user.

2016-12-15transport: add protocol policy config optionLibravatar Brandon Williams1-2/+73
Previously the `GIT_ALLOW_PROTOCOL` environment variable was used to specify a whitelist of protocols to be used in clone/fetch/push commands. This patch introduces new configuration options for more fine-grained control for allowing/disallowing protocols. This also has the added benefit of allowing easier construction of a protocol whitelist on systems where setting an environment variable is non-trivial. Now users can specify a policy to be used for each type of protocol via the 'protocol.<name>.allow' config option. A default policy for all unconfigured protocols can be set with the 'protocol.allow' config option. If no user configured default is made git will allow known-safe protocols (http, https, git, ssh, file), disallow known-dangerous protocols (ext), and have a default policy of `user` for all other protocols. The supported policies are `always`, `never`, and `user`. The `user` policy can be used to configure a protocol to be usable when explicitly used by a user, while disallowing it for commands which run clone/fetch/push commands without direct user intervention (e.g. recursive initialization of submodules). Commands which can potentially clone/fetch/push from untrusted repositories without user intervention can export `GIT_PROTOCOL_FROM_USER` with a value of '0' to prevent protocols configured to the `user` policy from being used. Fix remote-ext tests to use the new config to allow the ext protocol to be tested.

2016-10-10alternates: use a separate scratch spaceLibravatar Jeff King1-3/+1
The alternate_object_database struct uses a single buffer both for storing the path to the alternate, and as a scratch buffer for forming object names. This is efficient (since otherwise we'd end up storing the path twice), but it makes life hard for callers who just want to know the path to the alternate. They have to remember to stop reading after "alt->name - alt->base" bytes, and to subtract one for the trailing '/'. It would be much simpler if they could simply access a NUL-terminated path string. We could encapsulate this in a function which puts a NUL in the scratch buffer and returns the string, but that opens up questions about the lifetime of the result. The first time another caller uses the alternate, the scratch buffer may get other data tacked onto it. Let's instead just store the root path separately from the scratch buffer. There aren't enough alternates being stored for the duplicated data to matter for performance, and this keeps things simple and safe for the callers.

"git am -3" calls "git merge-recursive" when it needs to fall back to a three-way merge; this call has been turned into an internal subroutine call instead of spawning a separate subprocess. * js/am-3-merge-recursive-direct: merge-recursive: flush output buffer even when erroring out merge_trees(): ensure that the callers release output buffer merge-recursive: offer an option to retain the output in 'obuf' merge-recursive: write the commit title in one go merge-recursive: flush output buffer before printing error messages am -3: use merge_recursive() directly again merge-recursive: switch to returning errors instead of dying merge-recursive: handle return values indicating errors merge-recursive: allow write_tree_from_memory() to error out merge-recursive: avoid returning a wholesale struct merge_recursive: abort properly upon errors prepare the builtins for a libified merge_recursive() merge-recursive: clarify code in was_tracked() die(_("BUG")): avoid translating bug messages die("bug"): report bugs consistently t5520: verify that `pull --rebase` shows the helpful advice when failing

2016-08-06use strbuf_add_unique_abbrev() for adding short hashesLibravatar René Scharfe1-7/+4
Call strbuf_add_unique_abbrev() to add abbreviated hashes to strbufs instead of taking detours through find_unique_abbrev() and its static buffer. This is shorter and a bit more efficient. Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-07-26die("bug"): report bugs consistentlyLibravatar Johannes Schindelin1-1/+1
The vast majority of error messages in Git's source code which report a bug use the convention to prefix the message with "BUG:". As part of cleaning up merge-recursive to stop die()ing except in case of detected bugs, let's just make the remainder of the bug reports consistent with the de facto rule.

2016-07-14push: anonymize URL in status outputLibravatar Jeff King1-2/+5
Commit 47abd85 (fetch: Strip usernames from url's before storing them, 2009-04-17) taught fetch to anonymize URLs. The primary purpose there was to avoid sticking passwords in merge-commit messages, but as a side effect, we also avoid printing them to stderr. The push side does not have the merge-commit problem, but it probably should avoid printing them to stderr. We can reuse the same anonymizing function. Note that for this to come up, the credentials would have to appear either on the command line or in a git config file, neither of which is particularly secure. So people _should_ be switching to using credential helpers instead, which makes this problem go away. But that's no excuse not to improve the situation for people who for whatever reason end up using credentials embedded in the URL.
