Linus Torvalds	3c249c9506	Add "get_sha1()" helper function. This allows the programs to use various simplified versions of the SHA1 names, eg just say "HEAD" for the SHA1 pointed to by the .git/HEAD file etc. For example, this commit has been done with git-commit-tree $(git-write-tree) -p HEAD instead of the traditional "$(cat .git/HEAD)" syntax.	20 years ago
Rene Scharfe	87fec8fc9e	[PATCH] GIT: Create tar archives of tree on the fly Write commit ID to global extended pax header at the beginning of the tar file, if possible. get-tar-commit-id.c is an example program to get the ID back out of such a tar archive.

Rene Scharfe	db413479f1	[PATCH] Use read_object_with_reference() in tar-tree This patch replaces the usage of read_tree_with_tree_or_commit_sha1() with read_object_with_reference() in tar-tree. As a result the code that tries to figure out the commit time doesn't need to open the commit object 'by hand' any more.

Rene Scharfe	731ab9ccf2	[PATCH] create tar archives of tree on the fly This is an improved version of tar-tree, a streaming archive creator for GIT. The major added feature is blocking; all write(2) calls now have a size of 10240, just as GNU tar (and tape drives) likes them. The buffering overhead does not seem to degrade performance because most files in the repositories I tested this with are smaller than 10KB, so we need fewer system calls. File names are still restricted to 500 bytes and the archive format currently only allows for files up to 8GB. Both restrictions can be lifted if need be with more pax extended headers. The archive format used is the pax interchange format, i.e. POSIX tar format. It can be read by (and created with) GNU tar. If I read the specs correctly tar-tree should now be standards compliant (modulo bugs). Because it streams the archive (think ls-tree merged with cat-file), tar-tree doesn't need to create any temporary files. That makes it quite fast. It accepts tree IDs and commit IDs as first parameter. In the latter case tar-tree tries to get the commit date out of the committer line. Else all files in the archive are time-stamped with the current time. An optional second parameter is used as a path prefix for all files in the archive.
