2010-11-29unpack-trees: move all skip-worktree checks back to unpack_trees()Libravatar Nguyễn Thái Ngọc Duy2-9/+74
Earlier, the will_have_skip_worktree() checks are done in various places, which makes it hard to traverse the index tree-alike, required by excluded_from_list(). This patch moves all the checks into two loops in unpack_trees(). Entries in index in this operation can be classified into two groups: ones already in index before unpack_trees() is called and ones added to index after traverse_trees() is called. In both groups, before checking file status on worktree, the future skip-worktree bit must be checked, so that if an entry will be outside worktree, worktree should not be checked. For the first group, the future skip-worktree bit is precomputed and stored as CE_NEW_SKIP_WORKTREE in the first loop before traverse_trees() is called so that *way_merge() function does not need to compute it again. For the second group, because we don't know what entries will be in this group until traverse_trees() finishes, operations that need future skip-worktree check is delayed until CE_NEW_SKIP_WORKTREE is computed in the second loop. CE_ADDED is used to mark entries in the second group. CE_ADDED and CE_NEW_SKIP_WORKTREE are temporary flags used in unpack_trees(). CE_ADDED is only used by add_to_index(), which should not be called while unpack_trees() is running.

2010-11-12add: do not rely on dtype being NULL behaviorLibravatar Nguyễn Thái Ngọc Duy1-1/+2
Commit c84de70 (excluded_1(): support exclude files in index - 2009-08-20) added support for excluded() where dtype can be NULL. It was designed specifically for index matching because there was no other way to extract dtype information from index. It did not support wildcard matching (for example, "a*/" pattern would fail to match). The code was probably misread when commit 108da0d (git add: Add the "--ignore-missing" option for the dry run - 2010-07-10) was made because DT_UNKNOWN happens to be zero (NULL) too. Do not pass DT_UNKNOWN/NULL to excluded(), instead pass a pointer to a variable that contains DT_UNKNOWN. The real dtype will be extracted from worktree by excluded(), as expected.

2010-11-09Documentation: document show -sLibravatar Jonathan Nieder2-0/+7
Git's diff machinery has supported a -s (silence diff output) option as far back as v0.99~900 (Silent flag for show-diff, 2005-04-13), but the option is only advertised in an odd corner of the git diff-tree manual. The main use is to retrieve basic metadata about a commit: git show -s rev Explain this in the 'git log' manual and provide an example in the 'git show' examples section. This is kind of a cop-out, since it would be more useful to explain it in the 'git show' manual proper, which says: The command takes options applicable to the git diff-tree command to control how the changes the commit introduces are shown. This manual page describes only the most frequently used options. Fixing that is a larger task for another day.

Commit c84de70 (excluded_1(): support exclude files in index - 2009-08-20) tries to work around the fact that there is no directory/file information in index entries, therefore EXC_FLAG_MUSTBEDIR match would fail.

2010-10-06work around buggy S_ISxxx(m) implementationsLibravatar René Scharfe1-3/+10
There are buggy implementations of S_ISxxx(m) macros on some platforms (e.g. NetBSD). The issue is that NetBSD doesn't take care to wrap its macro arguments in parentheses, so on Linux and sane systems we have S_ISREG(m) defined as something like: (((m) & S_IFMT) == S_IFREG) But on NetBSD: ((m & _S_IFMT) == _S_IFREG) Since a caller in builtin/diff.c called our macro as `S_IFREG | 0644' this bug introduced a logic error on NetBSD, since the precedence of bit-wise & is higher than | in C.

2010-10-06xdiff: cast arguments for ctype functions to unsigned charLibravatar Jonathan Nieder3-10/+11
The ctype functions isspace(), isalnum(), et al take an integer argument representing an unsigned character, or -1 for EOF. On platforms with a signed char, it is unsafe to pass a char to them without casting it to unsigned char first. Most of git is already shielded against this by the ctype implementation in git-compat-util.h, but xdiff, which uses libc ctype.h, ought to be fixed.

2010-10-03setup: make sure git dir path is in a permanent bufferLibravatar Jonathan Nieder1-1/+3
If setup_git_env() is run before the usual repository discovery sequence and .git is a file with the text gitdir: <path> (with <path> any string) then the in-core git_dir variable is set to the result of converting <path> to an absolute path using make_absolute_path(). Unfortunately make_absolute_path() returns its result in a static buffer that is overwritten by later calls. Such a call could cause later accesses to git_dir (from git_pathdup(), for example) to read the wrong path, leaving git very confused. It is not obvious whether any existing code in git will trigger the problem, but in any case, it is worth a few dozen bytes to copy the return value from make_absolute_path() for some added peace of mind.
