* Convert GIT_SHA1_RAWSZ used for allocation to GIT_MAX_RAWSZbrian m. carlson2017-03-261-1/+1
| | | | | | | | | | | | | Since we will likely be introducing a new hash function at some point, and that hash function might be longer than 20 bytes, use the constant GIT_MAX_RAWSZ, which is designed to be suitable for allocations, instead of GIT_SHA1_RAWSZ. 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.

* Define new hash-size constants for allocating memorybrian m. carlson2017-03-261-1/+5
| | | | | | | | | | Since we will want to transition to a new hash at some point in the future, and that hash may be larger in size than 160 bits, introduce two constants that can be used for allocating a sufficient amount of memory. They can be increased to reflect the largest supported hash size. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * | odb_pack_keep(): stop generating keepfile nameJeff King2017-03-161-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The odb_pack_keep() function generates the name of a .keep file and opens it. This has two problems: 1. It requires a fixed-size buffer to create the filename and doesn't notice when the result is truncated. 2. Of the two callers, one sometimes wants to open a filename it already has, which makes things awkward (it has to do so manually, and skips the leading-directory creation). Instead, let's have odb_pack_keep() just open the file. Generating the name isn't hard, and a future patch will switch callers over to odb_pack_name() anyway.

Let's make it available, but clean up a few things: 1. Name it odb_pack_name(), as the original sha1_get_pack_name() is long but not all that descriptive. 2. Switch the strbuf argument to the beginning, so that it matches similar path-building functions like git_path_buf(). 3. Clean up the out-dated docstring and move it to the public declaration.

|\ \ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our source code has used the SHA1_HEADER cpp macro after "#include" in the C code to switch among the SHA-1 implementations.

This functionality allows rapid development with fewer errors. However, such functionality generally does not allow the specification of project-specific defines or command-line options. Since the SHA1_HEADER include is not defined in such a case, developers see spurious errors when using these tools. Furthermore, there are known implementations of "cc" whose '#include' is unhappy with this construct. Instead of using SHA1_HEADER, create a hash.h header and use #if and #elif to select the desired header. Have the Makefile pass an appropriate option to help the header select the right implementation to use.

The expanded ref names are not fully qualified, and may be outside of the refs/heads/ namespace (e.g., "@" expands to "HEAD", and "@{upstream}" is likely to be in "refs/remotes/"). This is OK for callers like dwim_ref() which are primarily interested in resolving the resulting name, no matter where it is. But callers like "git branch" treat the result as a branch name in refs/heads/. When we expand to a ref outside that namespace, the results are very confusing (e.g., "git branch @" tries to create refs/heads/HEAD, which is nonsense). Callers can't know from the returned string how the expansion happened (e.g., did the user really ask for a branch named "HEAD", or did we do a bogus expansion?). One fix would be to return some out-parameters describing the types of expansion that occurred. This has the benefit that the caller can generate precise error messages ("I understood @{upstream} to mean origin/master, but that is a remote tracking branch, so you cannot create it as a local name"). However, out-parameters make the function interface somewhat cumbersome. Instead, let's do the opposite: let the caller tell us which elements to expand. That's easier to pass in, and none of the callers give more precise error messages than "@{upstream} isn't a valid branch name" anyway (which should be sufficient). The strbuf_branchname() function needs a similar parameter, as most of the callers access interpret_branch_name() through it. We can break the callers down into two groups: 1. Callers that are happy with any kind of ref in the result. We pass "0" here, so they continue to work without restrictions. This includes merge_name(), the reflog handling in add_pending_object_with_path(), and substitute_branch_name(). This last is what powers dwim_ref(). 2. Callers that have funny corner cases (mostly in git-branch and git-checkout). These need to make use of the new parameter, but I've left them as "0" in this patch, and will address them individually in follow-on patches.

The problem with this change is that real_path() calls strbuf_realpath() with die_on_error = 1 while real_pathdup() calls it with die_on_error = 0. Meaning that in cases where real_path() causes Git to die() with an error message, real_pathdup() is silent and returns NULL instead. The callers, however, are ill-prepared for that change, as they expect the return value to be non-NULL (and otherwise the function died with an appropriate error message). Fix this by extending real_pathdup()'s signature to accept the die_on_error flag and simply pass it through to strbuf_realpath(), and then adjust all callers after a careful audit whether they would handle NULLs well.

It also handles the simpler "section.key", and the caller is responsible for distinguishing the two from its out-parameters. Most callers who _only_ want "section.key" would just use a strcmp(var, "section.key"), since there is no parsing required. However, they may still use parse_config_key() if their "section" variable isn't a constant (an example of this is in parse_hide_refs_config). Using the parse_config_key is a bit clunky, though: const char *subsection; int subsection_len; const char *key; if (!parse_config_key(var, section, &subsection, &subsection_len, &key) && !subsection) { /* matched! */ } Instead, let's treat a NULL subsection as an indication that the caller does not expect one. That lets us write: const char *key; if (!parse_config_key(var, section, NULL, NULL, &key)) { /* matched! */ } Existing callers should be unaffected, as passing a NULL subsection would currently segfault.

The actual file creation is done by a callback function, which, if it fails, should set errno to EISDIR or ENOENT according to the convention of open(). raceproof_create_file() detects such failures, and respectively either tries to delete empty directories that might be in the way of the file or tries to create the containing directories. Then it retries the callback function. This function is not yet used.

The reason is that we know that some hierarchies (like refs/tags) are not meant to change, and that unknown hierarchies might not want reflogs at all (e.g., a hypothetical refs/foo might be meant to change often and drop old history immediately). However, sometimes it is useful to override this decision and simply log for all refs, because the safety and audit trail is more important than the performance implications of keeping the log around. This patch introduces a new "always" mode for the core.logallrefupdates option which will log updates to everything under refs/, regardless where in the hierarchy it is (we still will not log things like ORIG_HEAD and FETCH_HEAD, which are known to be transient).
