git/ls-tree.c, branch v1.2.2

Only use a single parser for tree objects

2006-01-26T09:08:29Z

This makes read_tree_recursive and read_tree take a struct tree instead of a buffer. It also move the declaration of read_tree into tree.h (where struct tree is defined), and updates ls-tree and diff-index (the only places that presently use read_tree*()) to use the new versions.

ls-tree: chomp leading directories when run from a subdirectory

2005-12-23T22:01:32Z

When run from a subdirectory, even though we filtered the output based on where we were using pathspec, we wrote out the repository relative paths, not subtree relative paths. This changes things so that it shows only the current subdirectory relative paths. For example, in Documentation subdirectory of git itself, this used to be the case: $ git-ls-tree --name-only HEAD | grep how Documentation/git-show-branch.txt Documentation/git-show-index.txt Documentation/howto-index.sh Documentation/howto But now it does this instead: $ git-ls-tree --name-only HEAD | grep how git-show-branch.txt git-show-index.txt howto-index.sh howto There are two things to keep in mind. 1. This shows nothing. $ git-ls-tree --name-only HEAD ../ppc/ This is to make things consistent with ls-files, which refuses relative path that goes uplevel. 2. These show things in full repository relative paths. In this case, paths outside the current subdirectory are also shown. $ git-ls-tree --name-only --full-name HEAD | grep how Documentation/git-show-branch.txt Documentation/git-show-index.txt Documentation/howto-index.sh Documentation/howto $ git-ls-tree --name-only --full-name HEAD ../ppc/ ppc/sha1.c ppc/sha1.h ppc/sha1ppc.S The flag --full-name gives the same behaviour as 1.0, so it ought to be the default if we really care about the backward compatibility, but in practice no Porcelain runs ls-tree from a subdirectory yet, and without --full-name is more human friendly, so hopefully the default being not --full-name would be acceptable.

ls-tree: --name-only

2005-12-01T22:54:00Z

Fingers of some "git diff" users are trained to do --name-only which git-ls-tree unfortunately does not take. With this, cd sub/directory && git-ls-tree -r --name-only .. would show only the names not object names nor modes. I threw in another synonym --name-status only for usability, but obviously ls-tree does not do any comparison so what it does is the same as --name-only. Signed-off-by: Junio C Hamano

ls-tree: resurrect '-d' to mean 'show trees only'

2005-12-01T22:43:54Z

With this: git-ls-tree -d HEAD -- drivers/net/ shows only immediate subtrees of drivers/net. git-ls-tree -d -t HEAD -- drivers/net/ shows drivers, drivers/net and immediate subtrees of drivers/net. git-ls-tree -d -r HEAD -- drivers/net/ shows drivers, drivers/net and all subtrees of drivers/net (but not blobs).

git-ls-tree: add "-t" option to always show the tree entries

2005-12-01T20:27:22Z

The old (new) behaviour was that it only shows trees if the object is specified exactly, and recursive is not set. That makes sense, because there is obviously nothing else it can show for that case. However, with the new "-t" option, it will show the tree even with "-r", as it traverses down into it. NOTE! This also means that it will show all trees leading up to that tree. For example, if you do a git-ls-tree -t HEAD -- drivers/char/this/file/does/not/exist it will show the trees that lead up to the files that do not exist: [torvalds@g5 linux]$ git-ls-tree -t HEAD -- drivers/char/this/file/does/not/exist 040000 tree 9cb687b77dcd64bf82e9a73214db467c964c1266 drivers 040000 tree 298e2fadf0ff3867d1ef49936fd2c7bf6ce1eb66 drivers/char [torvalds@g5 linux]$ and note how this is true even though I didn't specify "-r": the fact that I supplied a pathspec automatically implies "enough recursion" for that particular pathspec. I think the code is cleaner and easier to understand too: the patch looks bigger, but it's really just splitting up the "should we recurse into this tree" into a function of its own.

ls-tree: Resurrect funny name quoting lost during rewrite.

2005-11-29T07:03:12Z

The rewrite to match ls-files/diff-tree behaviour accidentally lost the name quoting. I am not proud about this code, but this would get the test going. Signed-off-by: Junio C Hamano

ls-tree: further tweaks of the rewrite

2005-11-29T07:00:14Z

It modifies the selection a bit, so that a pathspec that is a superset of a particular tree path will always cause it to recurse into that tree. As an example, let's say that we do git-ls-tree HEAD drivers/char _without_ the "-r". What will happen is that it will start out doing all the base tree, and for "drivers" it will notice that it's a proper subset of "drivers/char", so it will always recurse into _that_ tree (but not into other trees). Then, it will not match anything else than "char" in that subdirectory, and because that's not a proper superset (it's an exact match), it will _not_ recurse into it, so you get: [torvalds@g5 linux]$ ~/git/git-ls-tree HEAD drivers/char 040000 tree 9568cda453aae205bb58983747fa73b9696d9d51 drivers/char which is what you got with the old git-ls-tree too. But interestingly, if you add the slash, it will become a proper superset and it will recurse into _that_ subdirectory (but no deeper: so if you want all subdirectories _below_ drivers/char/, you still need to give "-r"): [torvalds@g5 linux]$ ~/git/git-ls-tree HEAD drivers/char/ 100644 blob 2b6b1d772ed776fff87927fc34adc2e40500218e drivers/char/.gitignore 100644 blob 56b8a2e76ab10a5c21787cb7068a846075cbaffd drivers/char/ChangeLog 100644 blob 970f70d498f4c814e1cf3362e33d7e23ac53c299 drivers/char/Kconfig ... See? This is on top of the previous two diffs, holler if you want a whole new "everything combined" version.. It hasn't gotten lots of testing, but it should work. Linus

ls-tree: further cleanup to parallel ls-files.

2005-11-29T07:00:14Z

To get more a "git-ls-files" approach, this trivial patch (on top of my previous one) enables recursion, and doesn't show partial trees. [jc: after further discussion, this version enables recursion by default, and you can disable it with "-d" flag. git-ls-tree -d HEAD Documentation/no/such/directory shows Documentation tree (without -d it shows nothing). git-ls-tree HEAD shows everything from the tree. Only to get the single level from the top git-ls-tree -d HEAD is needed. But there is no way to get the single level with pathspec. You need to extract the object name of Documentation tree from the parent tree and run git-ls-tree -d $tree_id_of_Documentation_tree to get something similar to what you can get from the current git-ls-tree HEAD Documentation ]

ls-tree: major rewrite to do pathspec

2005-11-29T07:00:14Z

git-ls-tree should be rewritten to use a pathspec the same way everybody else does. Right now it's the odd man out: if you do git-ls-tree HEAD divers/char drivers/ it will show the same files _twice_, which is not how pathspecs in general work. How about this patch? It breaks some of the git-ls-tree tests, but it makes git-ls-tree work a lot more like other git pathspec commands, and it removes more than 150 lines by re-using the recursive tree traversal (but the "-d" flag is gone for good, so I'm not pushing this too hard).
