An earlier commit 366bfcb6 broke git-add by moving read_cache() call down, because it wanted the directory walking code to grab paths that are already in the index. The change serves its purpose, but introduces a regression because the responsibility of avoiding unnecessary reindexing by matching the cached stat is shifted nowhere. This makes it the job of add_file_to_index() function. Signed-off-by: NJunio C Hamano <gitster@pobox.com>

This makes all low-level functions defined in read-cache.c to take an explicit index_state structure as their first parameter, to specify which index to work on. These functions traditionally operated on "the_index" and were named foo_cache(); the counterparts this patch introduces are called foo_index(). The traditional foo_cache() functions are made into macros that give "the_index" to their corresponding foo_index() functions. Signed-off-by: NJunio C Hamano <junkio@cox.net>

The code to match up index entries with the filesystem was stupidly broken. We shouldn't compare the filesystem stat() information with S_IFDIRLNK, since that's purely a git-internal value, and not what the filesystem uses (on the filesystem, it's just a regular directory). Also, don't bother to make the stat() time comparisons etc for DIRLNK entries in ce_match_stat_basic(), since we do an exact match for these things, and the hints in the stat data simply doesn't matter. This fixes "git status" with submodules that haven't been checked out in the supermodule.

This is the promised cleaned-up version of teaching directory traversal (ie the "read_directory()" logic) about subprojects. That makes "git add" understand to add/update subprojects. It now knows to look at the index file to see if a directory is marked as a subproject, and use that as information as whether it should be recursed into or not. It also generally cleans up the handling of directory entries when traversing the working tree, by splitting up the decision-making process into small functions of their own, and adding a fair number of comments. Finally, it teaches "add_file_to_cache()" that directory names can have slashes at the end, since the directory traversal adds them to make the difference between a file and a directory clear (it always did that, but my previous too-ugly-to-apply subproject patch had a totally different path for subproject directories and avoided the slash for that case).

This fixes a total thinko in my original series: subprojects do *not* sort like directories, because the index is sorted purely by full pathname, and since a subproject shows up in the index as a normal NUL-terminated string, it never has the issues with sorting with the '/' at the end. So if you have a subproject "proj" and a file "proj.c", the subproject sorts alphabetically before the file in the index (and must thus also sort that way in a tree object, since trees sort as the index). In contrast, it you have two files "proj/file" and "proj.c", the "proj.c" will sort alphabetically before "proj/file" in the index. The index itself, of course, does not actually contain an entry "proj/", but in the *tree* that gets written out, the tree entry "proj" will sort after the file entry "proj.c", which is the only real magic sorting rule. In other words: the magic sorting rule only affects tree entries, and *only* affects tree entries that point to other trees (ie are of the type S_IFDIR). Anyway, that thinko just means that we should remove the special case to make S_ISDIRLNK entries sort like S_ISDIR entries. They don't. They sort like normal files.

This teaches the really fundamental core SHA1 object handling routines about gitlinks. We can compare trees with gitlinks in them (although we can not actually generate patches for them yet - just raw git diffs), and they show up as commits in "git ls-tree".

This function was not called "add_file_to_cache()" only because an ancient program, update-cache, used that name as an internal function name that does something slightly different. Now that is gone, we can take over the better name. The plan is to name all functions that operate on the default index xxx_cache(). Later patches create a variant of them that take an explicit parameter xxx_index(), and then turn xxx_cache() functions into macros that use "the_index".

Some systems have sizeof(off_t) == 8 while sizeof(size_t) == 4. This implies that we are able to access and work on files whose maximum length is around 2^63-1 bytes, but we can only malloc or mmap somewhat less than 2^32-1 bytes of memory. On such a system an implicit conversion of off_t to size_t can cause the size_t to wrap, resulting in unexpected and exciting behavior. Right now we are working around all gcc warnings generated by the -Wshorten-64-to-32 option by passing the off_t through xsize_t(). In the future we should make xsize_t on such problematic platforms detect the wrapping and die if such a file is accessed. Signed-off-by: NShawn O.

Some file systems that can host git repositories and their working copies do not support symbolic links. But then if the repository contains a symbolic link, it is impossible to check out the working copy. This patch enables partial support of symbolic links so that it is possible to check out a working copy on such a file system. A new flag core.symlinks (which is true by default) can be set to false to indicate that the filesystem does not support symbolic links. In this case, symbolic links that exist in the trees are checked out as small plain files, and checking in modifications of these files preserve the symlink property in the database (as long as an entry exists in the index). Of course, this does not magically make symbolic links work on such defective file systems; hence, this solution does not help if the working copy relies on that an entry is a real symbolic link.

One of them is obviously redundent, and the most used one requires more stack space and a bunch of strcmp() all over the place.

In some cases we did not even bother to check the return value of mmap() and just assume it worked. This is bad, because if we are out of virtual address space the kernel returned MAP_FAILED and we would attempt to dereference that address, segfaulting without any real error output to the user. We are replacing all calls to mmap() with xmmap() and moving all MAP_FAILED checking into that single location. If a mmap call fails we try to release enough least-recently-used pack windows to possibly succeed, then retry the mmap() attempt. If we cannot mmap even after releasing pack memory then we die() as none of our callers have any reasonable recovery strategy for a failed mmap. Signed-off-by: NShawn O.

On Solaris nanosleep(2) is not available in libc; you need to link with -lrt to get it. The purpose of the loop is to wait until the next filesystem timestamp granularity, and the code uses subsecond sleep in the hope that it can shorten the delay to 0.5 seconds on average instead of a full second. It is probably not worth depending on an extra library for this. We might want to yank out the whole "racy-git avoidance is costly later at runtime, so let's delay writing the index out" codepath later, but that is a separate issue and needs some testing on large trees to figure it out. After playing with the kernel tree, I have a feeling that the whole thing may not be worth it. Signed-off-by: NJunio C Hamano <junkio@cox.net>

Immediately after a bulk checkout, most of the paths in the working tree would have the same timestamp as the index file, and this would force ce_match_stat() to take slow path for all of them. When writing an index file out, if many of the paths have very new (read: the same timestamp as the index file being written out) timestamp, we are better off delaying the return from the command, to make sure that later command to touch the working tree files will leave newer timestamps than recorded in the index, thereby avoiding to take the slow path.
