2018-03-15ls-remote: pass ref prefixes when requesting a remote's refsLibravatar Brandon Williams1-0/+7
Construct an argv_array of ref prefixes based on the patterns supplied via the command line and pass them to 'transport_get_remote_refs()' to be used when communicating protocol v2 so that the server can limit the ref advertisement based on those prefixes.

2017-11-22log: add option to choose which refs to decorateLibravatar Rafael Ascensão1-0/+24
When `log --decorate` is used, git will decorate commits with all available refs. While in most cases this may give the desired effect, under some conditions it can lead to excessively verbose output. Introduce two command line options, `--decorate-refs=<pattern>` and `--decorate-refs-exclude=<pattern>` to allow the user to select which refs are used in decoration. When "--decorate-refs=<pattern>" is given, only the refs that match the pattern are used in decoration. The refs that match the pattern when "--decorate-refs-exclude=<pattern>" is given, are never used in decoration. These options follow the same convention for mixing negative and positive patterns across the system, assuming that the inclusive default is to match all refs available. (1) if there is no positive pattern given, pretend as if an inclusive default positive pattern was given; (2) for each candidate, reject it if it matches no positive pattern, or if it matches any one of the negative patterns. The rules for what is considered a match are slightly different from the rules used elsewhere. Commands like `log --glob` assume a trailing '/*' when glob chars are not present in the pattern. This makes it difficult to specify a single ref. On the other hand, commands like `describe --match --all` allow specifying exact refs, but do not have the convenience of allowing "shorthand refs" like 'refs/heads' or 'heads' to refer to 'refs/heads/*'. The commands introduced in this patch consider a match if: (a) the pattern contains globs chars, and regular pattern matching returns a match. (b) the pattern does not contain glob chars, and ref '<pattern>' exists, or if ref exists under '<pattern>/' This allows both behaviours (allowing single refs and shorthand refs) yet remaining compatible with existent commands.

2017-11-06refs: tidy up and adjust visibility of the `ref_update` flagsLibravatar Michael Haggerty1-28/+39
The constants used for `ref_update::flags` were rather disorganized: * The definitions in `refs.h` were not close to the functions that used them. * Maybe constants were defined in `refs-internal.h`, making them visible to the whole refs module, when in fact they only made sense for the files backend. * Their documentation wasn't very consistent and partly still referred to sha1s rather than oids. * The numerical values followed no rational scheme Fix all of these problems. The main functional improvement is that some constants' visibility is now limited to `files-backend.c`.

2017-11-06prune_ref(): call `ref_transaction_add_update()` directlyLibravatar Michael Haggerty1-3/+1
`prune_ref()` needs to use the `REF_ISPRUNING` flag, but we want to make that flag private to the files backend. So instead of calling `ref_transaction_delete()`, which is a public function and therefore shouldn't allow the `REF_ISPRUNING` flag, change `prune_ref()` to call `ref_transaction_add_update()`, which is private to the refs module. (Note that we don't need any of the other services provided by `ref_transaction_delete()`.) This allows us to change `ref_transaction_update()` to reject the `REF_ISPRUNING` flag. Do so by adjusting `REF_TRANSACTION_UPDATE_ALLOWED_FLAGS`. Also add parentheses to its definition to avoid potential future mishaps.

2017-09-14refs: strip out not allowed flags from ref_transaction_updateLibravatar Thomas Gummerer1-0/+8
Callers are only allowed to pass certain flags into ref_transaction_update, other flags are internal to it. To prevent mistakes from the callers, strip the internal only flags out before continuing. This was noticed because of a compiler warning gcc 7.1.1 issued about passing a NULL parameter as second parameter to memcpy (through hashcpy): In file included from refs.c:5:0: refs.c: In function ‘ref_transaction_verify’: cache.h:948:2: error: argument 2 null where non-null expected [-Werror=nonnull] memcpy(sha_dst, sha_src, GIT_SHA1_RAWSZ); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from git-compat-util.h:165:0, from cache.h:4, from refs.c:5: /usr/include/string.h:43:14: note: in a call to function ‘memcpy’ declared here extern void *memcpy (void *__restrict __dest, const void *__restrict __src, ^~~~~~ The call to hascpy in ref_transaction_add_update is protected by the passed in flags, but as we only add flags there, gcc notices REF_HAVE_NEW or REF_HAVE_OLD flags could be passed in from the outside, which would potentially result in passing in NULL as second parameter to memcpy. Fix both the compiler warning, and make the interface safer for its users by stripping the internal flags out.

`for_each_bisect_ref()` is called by `for_each_bad_bisect_ref()` with a term "bad". This used to make it call `for_each_ref_in_submodule()` with a prefix "refs/bisect/bad". But the latter is the name of the reference that is being sought, so the empty string was being passed to the callback as the trimmed refname. Moreover, this questionable practice was turned into an error by b9c8e7f2fb prefix_ref_iterator: don't trim too much, 2017-05-22 It makes more sense (and agrees better with the documentation of `--bisect`) for the callers to receive the full reference names. So * Add a new function, `for_each_fullref_in_submodule()`, to the refs API. This plugs a gap in the existing functionality, analogous to `for_each_fullref_in()` but accepting a `submodule` argument. * Change `for_each_bad_bisect_ref()` to call the new function rather than `for_each_ref_in_submodule()`. * Add a test.

2017-06-18branch: add a --copy (-c) option to go with --move (-m)Libravatar Sahil Dua1-1/+8
Add the ability to --copy a branch and its reflog and configuration, this uses the same underlying machinery as the --move (-m) option except the reflog and configuration is copied instead of being moved. This is useful for e.g. copying a topic branch to a new version, e.g. work to work-2 after submitting the work topic to the list, while preserving all the tracking info and other configuration that goes with the branch, and unlike --move keeping the other already-submitted branch around for reference. Like --move, when the source branch is the currently checked out branch the HEAD is moved to the destination branch. In the case of --move we don't really have a choice (other than remaining on a detached HEAD) and in order to keep the functionality consistent, we are doing it in similar way for --copy too. The most common usage of this feature is expected to be moving to a new topic branch which is a copy of the current one, in that case moving to the target branch is what the user wants, and doesn't unexpectedly behave differently than --move would. One outstanding caveat of this implementation is that: git checkout maint && git checkout master && git branch -c topic && git checkout - Will check out 'maint' instead of 'master'. This is because the @{-N} feature (or its -1 shorthand "-") relies on HEAD reflogs created by the checkout command, so in this case we'll checkout maint instead of master, as the user might expect. What to do about that is left to a future change.

2017-05-23ref_transaction_prepare(): new optional step for reference updatesLibravatar Michael Haggerty1-27/+97
In the future, compound reference stores will sometimes need to modify references in two different reference stores at the same time, meaning that a single logical reference transaction might have to be implemented as two internal sub-transactions. They won't want to call `ref_transaction_commit()` for the two sub-transactions one after the other, because that wouldn't be atomic (the first commit could succeed and the second one fail). Instead, they will want to prepare both sub-transactions (i.e., obtain any necessary locks and do any pre-checks), and only if both prepare steps succeed, then commit both sub-transactions. Start preparing for that day by adding a new, optional `ref_transaction_prepare()` step to the reference transaction sequence, which obtains the locks and does any prechecks, reporting any errors that occur. Also add a `ref_transaction_abort()` function that can be used to abort a sub-transaction even if it has already been prepared. That is on the side of the public-facing API. On the side of the `ref_store` VTABLE, get rid of `transaction_commit` and instead add methods `transaction_prepare`, `transaction_finish`, and `transaction_abort`. A `ref_transaction_commit()` now basically calls methods `transaction_prepare` then `transaction_finish`.

2017-04-27timestamp_t: a new data type for timestampsLibravatar Johannes Schindelin1-4/+4
Git's source code assumes that unsigned long is at least as precise as time_t. Which is incorrect, and causes a lot of problems, in particular where unsigned long is only 32-bit (notably on Windows, even in 64-bit versions). So let's just use a more appropriate data type instead. In preparation for this, we introduce the new `timestamp_t` data type. By necessity, this is a very, very large patch, as it has to replace all timestamps' data type in one go. As we will use a data type that is not necessarily identical to `time_t`, we need to be very careful to use `time_t` whenever we interact with the system functions, and `timestamp_t` everywhere else.

files-backend at this point is still aware of the per-repo/worktree separation in refs, so it can handle a linked worktree. Some refs operations are known not working when current files-backend is used in a linked worktree (e.g. reflog). Tests will be written when refs_* functions start to be called with worktree backend to verify that they work as expected. Note: accessing a worktree of a submodule remains unaddressed. Perhaps after get_worktrees() can access submodule (or rather a new function get_submodule_worktrees(), that lists worktrees of a submodule), we can update this function to work with submodules as well.

get_ref_store() will soon be renamed to get_submodule_ref_store(). Together with future get_worktree_ref_store(), the three functions provide an appropriate ref store for different operation modes. New APIs will be added to operate directly on ref stores. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-02-22refs: convert each_reflog_ent_fn to struct object_idLibravatar brian m. carlson1-1/+1
Make each_reflog_ent_fn take two struct object_id pointers instead of two pointers to unsigned char. Convert the various callbacks to use struct object_id as well. Also, rename fsck_handle_reflog_sha1 to fsck_handle_reflog_oid. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
