2006-09-24Remove upload-tar and make git-tar-tree a thin wrapper to git-archiveLibravatar Junio C Hamano1-80/+50
The command now issues a big deprecation warning message and runs git-archive command with appropriate arguments. git-tar-tree $tree_ish $base always forces $base to be the leading directory name, so the --prefix parameter passed internally to git-archive is a slash appended to it, i.e. "--prefix=$base/".

2006-09-24git-tar-tree: Move code for git-archive --format=tar to archive-tar.cLibravatar Rene Scharfe1-313/+0
This patch doesn't change any functionality, it only moves code around. It makes seeing the few remaining lines of git-tar-tree code easier. ;-) Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-24git-tar-tree: Remove duplicate git_config() callLibravatar Rene Scharfe1-2/+0
generate_tar() eventually calls write_tar_archive() which does all the "real" work and which also calls git_config(git_tar_config). We only need to do this once. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-17git-tar-tree: devolve git-tar-tree into a wrapper for git-archiveLibravatar Rene Scharfe1-72/+18
This patch removes the custom tree walker tree_traverse(), and makes generate_tar() use write_tar_archive() and the infrastructure provided by git-archive instead. As a kind of side effect, make write_tar_archive() able to handle NULL as base directory, as this is what the new and simple generate_tar() uses to indicate the absence of a base directory. This was simpler and cleaner than playing tricks with empty strings. The behaviour of git-tar-tree should be unchanged (quick tests didn't indicate otherwise) except for the text of some error messages.

2006-09-02Replace uses of strdup with xstrdup.Libravatar Shawn Pearce1-1/+1
Like xmalloc and xrealloc xstrdup dies with a useful message if the native strdup() implementation returns NULL rather than a valid pointer. I just tried to use xstrdup in new code and found it to be missing. However I expected it to be present as xmalloc and xrealloc are already commonly used throughout the code. [jc: removed the part that deals with last_XXX, which I am finding more and more dubious these days.] Signed-off-by: Shawn O.

2006-08-21Add write_or_die(), a helper functionLibravatar Rene Scharfe1-23/+4
The little helper write_or_die() won't come back with bad news about full disks or broken pipes. It either succeeds or terminates the program, making additional error handling unnecessary. This patch adds the new function and uses it to replace two similar ones (the one in tar-tree originally has been copied from cat-file btw.). I chose to add the fd parameter which both lacked to make write_or_die() just as flexible as write() and thus suitable for lib-ification. There is a regression: error messages emitted by this function don't show the program name, while the replaced two functions did. That's acceptable, I think; a lot of other functions do the same.

In the name of Standardization, this cleanses the last usage string of mystical creatures. But they still dwell deep within the source and in some debug messages, it is said. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-04git-tar-tree: fix minor memory leakLibravatar Rene Scharfe1-2/+4
Free the root tree object buffer when we're done, plugging a minor leak in generate_tar(). Note: we cannot simply free(tree.buf) because this pointer is modified by tree_entry() calls in traverse_tree().

2006-07-29Call setup_git_directory() much earlierLibravatar Linus Torvalds1-5/+4
This changes the calling convention of built-in commands and passes the "prefix" (i.e. pathname of $PWD relative to the project root level) down to them. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-07-23tar-tree: add the "tar.umask" config optionLibravatar Willy Tarreau1-3/+18
By default, git-tar-tree(1) sets file and directories modes to 0666 or 0777. While this is both useful and acceptable for projects such as the Linux Kernel, it might be excessive for other projects. With this variable, it becomes possible to tell git-tar-tree(1) to apply a specific umask to the modes above. The special value "user" indicates that the user's current umask will be used. This should be enough for most projects, as it will lead to the same permissions as git-checkout(1) would use. The default value remains 0, which means world read-write.

2006-06-24Rename safe_strncpy() to strlcpy().Libravatar Peter Eriksen1-2/+2
This cleans up the use of safe_strncpy() even more. Since it has the same semantics as strlcpy() use this name instead. Also move the definition from inside path.c to its own file compat/strlcpy.c, and use it conditionally at compile time, since some platforms already has strlcpy(). It's included in the same way as compat/setenv.c. Signed-off-by: Peter Eriksen <s022018@student.dtu.dk> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-06-18git-tar-tree: no more void pointer arithmeticLibravatar Rene Scharfe1-2/+5

By being an internal command git-get-commit-id can make use of struct ustar_header and other stuff and stops wasting precious disk space.

2006-05-30tree_entry(): new tree-walking helper functionLibravatar Linus Torvalds1-13/+8
This adds a "tree_entry()" function that combines the common operation of doing a "tree_entry_extract()" + "update_tree_entry()". It also has a simplified calling convention, designed for simple loops that traverse over a whole tree: the arguments are pointers to the tree descriptor and a name_entry structure to fill in, and it returns a boolean "true" if there was an entry left to be gotten in the tree. This allows tree traversal with struct tree_desc desc; struct name_entry entry; desc.buf = tree->buffer; desc.size = tree->size; while (tree_entry(&desc, &entry) { ... use "entry.{path, sha1, mode, pathlen}" ... } which is not only shorter than writing it out in full, it's hopefully less error prone too. [ It's actually a tad faster too - we don't need to recalculate the entry pathlength in both extract and update, but need to do it only once. Also, some callers can avoid doing a "strlen()" on the result, since it's returned as part of the name_entry structure. However, by now we're talking just 1% speedup on "git-rev-list --objects --all", and we're definitely at the point where tree walking is no longer the issue any more. ] NOTE! Not everybody wants to use this new helper function, since some of the tree walkers very much on purpose do the descriptor update separately from the entry extraction. So the "extract + update" sequence still remains as the core sequence, this is just a simplified interface. We should probably add a silly two-line inline helper function for initializing the descriptor from the "struct tree" too, just to cut down on the noise from that common "desc" initializer.
