Once upon a time, create_symref() was used only to point HEAD at a branch name, and the variable names reflect that (e.g., calling the path git_HEAD). However, it is much more generic these days (and has been for some time). Let's update the variable names to make it easier to follow: - `ref_target` is now just `refname`. This is closer to the `ref` that is already in `cache.h`, but with the extra twist that "name" makes it clear this is the name and not a ref struct. Dropping "target" hopefully makes it clear that we are talking about the symref itself, not what it points to. - `git_HEAD` is now `ref_path`; the on-disk path corresponding to `ref`. - `refs_heads_master` is now just `target`; i.e., what the symref points at. This term also matches what is in the symlink(2) manpage (at least on Linux). - the buffer to hold the symref file's contents was simply called `ref`. It's now `buf` (admittedly also generic, but at least not actively introducing confusion with the other variable holding the refname).

In addition to matching stripped refs, one can now add hideRefs patterns that the full (unstripped) ref is matched against. To distinguish between stripped and full matches, those new patterns must be prefixed with a circumflex (^). This commit also removes support for the undocumented and unintended hideRefs settings ".have" (suppressing all "have" lines) and "capabilities^{}" (suppressing the capabilities line).

Loosen restrictions on refspecs by allowing patterns that have a "*" within a component instead of only as the whole component. Remove the logic to accept a single "*" as a whole component from check_refname_format(), and implement an extended form of that logic in check_refname_component(). Pass the pointer to the flags argument to the latter, as it has to clear REFNAME_REFSPEC_PATTERN bit when it sees "*". Teach check_refname_component() function to allow an asterisk "*" only when REFNAME_REFSPEC_PATTERN is set in the flags, and drop the bit after seeing a "*", to ensure that one side of a refspec contains at most one asterisk. This will allow us to accept refspecs such as `for/bar*:foo/baz*`. Any refspec which functioned before shall continue functioning with the new logic.

The ref_transaction_update() family of functions use the following convention for their old_sha1 parameters: * old_sha1 == NULL: Don't check the old value at all. * is_null_sha1(old_sha1): Ensure that the reference didn't exist before the transaction. * otherwise: Ensure that the reference had the specified value before the transaction. delete_ref() had a different convention, namely treating is_null_sha1(old_sha1) as "don't care". Change it to adhere to the standard convention to reduce the scope for confusion. Please note that it is now a bug to pass old_sha1=NULL_SHA1 to delete_ref() (because it doesn't make sense to delete a reference that you already know doesn't exist). This is consistent with the behavior of ref_transaction_delete(). Most of the callers of delete_ref() never pass old_sha1=NULL_SHA1 to delete_ref(), and are therefore unaffected by this change. The two exceptions are: * The call in cmd_update_ref(), which passed NULL_SHA1 if the old value passed in on the command line was 0{40} or the empty string. Change that caller to pass NULL in those cases. Arguably, it should be an error to call "update-ref -d" with the old value set to "does not exist", just as it is for the `--stdin` command "delete". But since this usage was accepted until now, continue to accept it. * The call in delete_branches(), which could pass NULL_SHA1 if deleting a broken or symbolic ref. Change it to pass NULL in these cases. Signed-off-by: NMichael Haggerty <mhagger@alum.mit.edu> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

"git clone" uses shortcuts when creating the initial set of references: * It writes them directly to packed-refs. * It doesn't lock the individual references (though it does lock the packed-refs file). * It doesn't check for refname conflicts between two new references or between one new reference and any hypothetical old ones. * It doesn't create reflog entries for the reference creations. This functionality was implemented in builtin/clone.c. But really that file shouldn't have such intimate knowledge of how references are stored. So provide a new function in the refs API, initial_ref_transaction_commit(), which can be used for initial reference creation. The new function is based on the ref_transaction interface. This means that we can make some other functions private to the refs module. That will be done in a followup commit. It would seem to make sense to add a test here that there are no existing references, because that is how the function *should* be used. But in fact, the "testgit" remote helper appears to call it *after* having set up refs/remotes/<name>/HEAD and refs/remotes/<name>/master, so we can't be so strict. For now, the function trusts its caller to only call it when it makes sense. Future commits will add some more limited sanity checks.

Change typedef each_ref_fn to take a "const struct object_id *oid" parameter instead of "const unsigned char *sha1". To aid this transition, implement an adapter that can be used to wrap old-style functions matching the old typedef, which is now called "each_ref_sha1_fn"), and make such functions callable via the new interface. This requires the old function and its cb_data to be wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be used as the cb_data for an adapter function, each_ref_fn_adapter(). This is an enormous diff, but most of it consists of simple, mechanical changes to the sites that call any of the "for_each_ref" family of functions. Subsequent to this change, the call sites can be rewritten one by one to use the new interface.

In the previous patch, git_snpath() is modified to allocate a new strbuf buffer because vsnpath() needs that. But that makes it awkward because git_snpath() receives a pre-allocated buffer from outside and has to copy data back. Rename it to strbuf_git_path() and make it receive strbuf directly. Using git_path() in update_refs_for_switch() which used to call git_snpath() is safe because that function and all of its callers do not keep any pointer to the round-robin buffer pool allocated by get_pathname().

We currently do not handle badly named refs well: $ cp .git/refs/heads/master .git/refs/heads/master.....@\*@\\. $ git branch fatal: Reference has invalid format: 'refs/heads/master.....@*@\.' $ git branch -D master.....@\*@\\. error: branch 'master.....@*@\.' not found. Users cannot recover from a badly named ref without manually finding and deleting the loose ref file or appropriate line in packed-refs. Making that easier will make it easier to tweak the ref naming rules in the future, for example to forbid shell metacharacters like '`' and '"', without putting people in a state that is hard to get out of. So allow "branch --list" to show these refs and allow "branch -d/-D" and "update-ref -d" to delete them. Other commands (for example to rename refs) will continue to not handle these refs but can be changed in later patches. Details: In resolving functions, refuse to resolve refs that don't pass the git-check-ref-format(1) check unless the new RESOLVE_REF_ALLOW_BAD_NAME flag is passed. Even with RESOLVE_REF_ALLOW_BAD_NAME, refuse to resolve refs that escape the refs/ directory and do not match the pattern [A-Z_]* (think "HEAD" and "MERGE_HEAD"). In locking functions, refuse to act on badly named refs unless they are being deleted and either are in the refs/ directory or match [A-Z_]*. Just like other invalid refs, flag resolved, badly named refs with the REF_ISBROKEN flag, treat them as resolving to null_sha1, and skip them in all iteration functions except for for_each_rawref. Flag badly named refs (but not symrefs pointing to badly named refs) with a REF_BAD_NAME flag to make it easier for future callers to notice and handle them specially. For example, in a later patch for-each-ref will use this flag to detect refs whose names can confuse callers parsing for-each-ref output. In the transaction API, refuse to create or update badly named refs, but allow deleting them (unless they try to escape refs/ and don't match [A-Z_]*).

In _commit, ENOTDIR can happen in the call to lock_ref_sha1_basic, either when we lstat the new refname or if the name checking function reports that the same type of conflict happened. In both cases, it means that we can not create the new ref due to a name conflict. Start defining specific return codes for _commit. TRANSACTION_NAME_CONFLICT refers to a failure to create a ref due to a name conflict with another ref. TRANSACTION_GENERIC_ERROR is for all other errors. When "git fetch" is creating refs, name conflicts differ from other errors in that they are likely to be resolved by running "git remote prune <remote>". "git fetch" currently inspects errno to decide whether to give that advice. Once it switches to the transaction API, it can check for TRANSACTION_NAME_CONFLICT instead.
