2017-03-21prefix_filename: return newly allocated stringJeff King
The prefix_filename() function returns a pointer to static storage, which makes it easy to use dangerously. We already fixed one buggy caller in hash-object recently, and the calls in apply.c are suspicious (I didn't dig in enough to confirm that there is a bug, but we call the function once in apply_all_patches() and then again indirectly from parse_chunk()). Let's make it harder to get wrong by allocating the return value. For simplicity, we'll do this even when the prefix is empty (and we could just return the original file pointer). That will cause us to allocate sometimes when we wouldn't otherwise need to, but this function isn't called in performance critical code-paths (and it already _might_ allocate on any given call, so a caller that cares about performance is questionable anyway). The downside is that the callers need to remember to free() the result to avoid leaking. Most of them already used xstrdup() on the result, so we know they are OK. The remainder have been converted to use free() as appropriate. I considered retaining a prefix_filename_unsafe() for cases where we know the static lifetime is OK (and handling the cleanup is awkward). This is only a handful of cases, though, and it's not worth the mental energy in worrying about whether the "unsafe" variant is OK to use in any situation.

2017-03-21prefix_filename: drop length parameterJeff King
This function takes the prefix as a ptr/len pair, but in every caller the length is exactly strlen(ptr). Let's simplify the interface and just take the string. This saves callers specifying it (and in some cases handling a NULL prefix). In a handful of cases we had the length already without calling strlen, so this is technically slower. But it's not likely to matter (after all, if the prefix is non-empty we'll allocate and copy it into a buffer anyway).

2016-11-28get_worktrees() must return main worktree as first item even on errorNguyễn Thái Ngọc Duy
This is required by git-worktree.txt, stating that the main worktree is the first line (especially in --porcelain mode when we can't just change behavior at will). There's only one case when get_worktrees() may skip main worktree, when parse_ref() fails. Update the code so that we keep first item as main worktree and return something sensible in this case: - In user-friendly mode, since we're not constraint by anything, returning "(error)" should do the job (we already show "(detached HEAD)" which is not machine-friendly). Actually errors should be printed on stderr by parse_ref() (*) - In plumbing mode, we do not show neither 'bare', 'detached' or 'branch ...', which is possible by the format description if I read it right. Careful readers may realize that when the local variable "head_ref" in get_main_worktree() is emptied, add_head_info() will do nothing to wt->head_sha1. But that's ok because head_sha1 is zero-ized in the previous patch. (*) Well, it does not. But it's supposed to be a stop gap implementation until we can reuse refs code to parse "ref: " stuff in HEAD, from resolve_refs_unsafe(). Now may be the time since refs refactoring is mostly done.

2016-04-22worktree.c: check whether branch is rebased in another worktreeNguyễn Thái Ngọc Duy
This function find_shared_symref() is used in a couple places: 1) in builtin/branch.c: it's used to detect if a branch is checked out elsewhere and refuse to delete the branch. 2) in builtin/notes.c: it's used to detect if a note is being merged in another worktree 3) in branch.c, the function die_if_checked_out() is actually used by "git checkout" and "git worktree add" to see if a branch is already checked out elsewhere and refuse the operation. In cases 1 and 3, if a rebase is ongoing, "HEAD" will be in detached mode, find_shared_symref() fails to detect it and declares "no branch is checked out here", which is not really what we want. This patch tightens the test. If the given symref is "HEAD", we try to detect if rebase is ongoing. If so return the branch being rebased. This makes checkout and branch delete operations safer because you can't checkout a branch being rebased in another place, or delete it. Special case for checkout. If the current branch is being rebased, git-rebase.sh may use "git checkout" to abort and return back to the original branch. The updated test in find_shared_symref() will prevent that and "git rebase --abort" will fail as a result. find_shared_symref() and die_if_checked_out() have to learn a new option ignore_current_worktree to loosen the test a bit.

2016-02-22use xmallocz to avoid size arithmeticJeff King
We frequently allocate strings as xmalloc(len + 1), where the extra 1 is for the NUL terminator. This can be done more simply with xmallocz, which also checks for integer overflow. There's no case where switching xmalloc(n+1) to xmallocz(n) is wrong; the result is the same length, and malloc made no guarantees about what was in the buffer anyway. But in some cases, we can stop manually placing NUL at the end of the allocated buffer. But that's only safe if it's clear that the contents will always fill the buffer. In each case where this patch does so, I manually examined the control flow, and I tried to err on the side of caution.

Since the real HEAD is now populated with its proper final value, the value of the temporary HEAD truly no longer matters, and any value which looks like an object ID is good enough to satisfy is_git_directory().

2015-07-20worktree: add_worktree: construct worktree-population command locallyEric Sunshine
The caller of add_worktree() provides it with a command to invoke to populate the new worktree. This was a useful abstraction during the conversion of "git checkout --to" functionality to "git worktree add" since git-checkout and git-worktree constructed the population command differently. However, now that "git checkout --to" has been retired, and add_worktree() has access to the options given to "worktree add", this extra indirection is no longer useful and makes the code a bit convoluted. Moreover, the eventual goal is for git-worktree to make setting of HEAD and worktree population distinct operations, whereas they are currently conflated into a single git-checkout invocation. As such, add_worktree() will eventually invoke other commands in addition to the worktree population command, so it will be doing command construction itself anyhow. Therefore, relocate construction of the worktree population command from add() to add_worktree().

We assign a local 'struct argv_array' to child_process.env, rather than utilizing the child_process.env_array 'struct argv_array', because future patches will make add_worktree() invoke additional sub-commands, and it's simpler to populate the environment array just once, whereas child_process.env_array gets cleared after each invocation, thus would require re-population for each sub-command.
