Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500 + +initial commit +------------------------------------------------ + +The tree object is the tree we examined first, and this commit is +unusual in that it lacks any parent. + +Most commits have only one parent, but it is also common for a commit +to have multiple parents. In that case the commit represents a +merge, with the parent references pointing to the heads of the merged +branches. + +Besides blobs, trees, and commits, the only remaining type of object +is a "tag", which we won't discuss here; refer to gitlink:git-tag[1] +for details. + +So now we know how git uses the object database to represent a +project's history: + + * "commit" objects refer to "tree" objects representing the + snapshot of a directory tree at a particular point in the + history, and refer to "parent" commits to show how they're + connected into the project history. + * "tree" objects represent the state of a single directory, + associating directory names to "blob" objects containing file + data and "tree" objects containing subdirectory information. + * "blob" objects contain file data without any other structure. + * References to commit objects at the head of each branch are + stored in files under .git/refs/heads/. + * The name of the current branch is stored in .git/HEAD. + +Note, by the way, that lots of commands take a tree as an argument. +But as we can see above, a tree can be referred to in many different +ways--by the SHA1 name for that tree, by the name of a commit that +refers to the tree, by the name of a branch whose head refers to that +tree, etc.--and most such commands can accept any of these names. + +In command synopses, the word "tree-ish" is sometimes used to +designate such an argument. + +The index file +-------------- + +The primary tool we've been using to create commits is "git commit +-a", which creates a commit including every change you've made to +your working tree. But what if you want to commit changes only to +certain files? Or only certain changes to certain files? + +If we look at the way commits are created under the cover, we'll see +that there are more flexible ways creating commits. + +Continuing with our test-project, let's modify file.txt again: + +------------------------------------------------ +$ echo "hello world, again" >>file.txt +------------------------------------------------ + +but this time instead of immediately making the commit, let's take an +intermediate step, and ask for diffs along the way to keep track of +what's happening: + +------------------------------------------------ +$ git diff +--- a/file.txt ++++ b/file.txt +@@ -1 +1,2 @@ + hello world! ++hello world, again +$ git update-index file.txt +$ git diff +------------------------------------------------ + +The last diff is empty, but no new commits have been made, and the +head still doesn't contain the new line: + +------------------------------------------------ +$ git-diff HEAD +diff --git a/file.txt b/file.txt +index a042389..513feba 100644 +--- a/file.txt ++++ b/file.txt +@@ -1 +1,2 @@ + hello world! ++hello world, again +------------------------------------------------ + +So "git diff" is comparing against something other than the head. +The thing that it's comparing against is actually the index file, +which is stored in .git/index in a binary format, but whose contents +we can examine with ls-files: + +------------------------------------------------ +$ git ls-files --stage +100644 513feba2e53ebbd2532419ded848ba19de88ba00 0 file.txt +$ git cat-file -t 513feba2 +blob +$ git cat-file blob 513feba2 +hello world, again +------------------------------------------------ + +So what our "git update-index" did was store a new blob and then put +a reference to it in the index file.
