Junio C Hamano	4b37666ccb	builtin-bundle create - use lock_file "git bundle create" left an invalid, partially written bundle if an error occured during creation. Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Mark Levedahl	21a02980f9	builtin-bundle - use buffered reads for bundle header This eliminates all use of byte-at-a-time reading of data in this function: as Junio noted, a bundle file is seekable so we can reset the file position to the first part of the pack-file using lseek after reading the header.

Mark Levedahl	442b67a559	builtin-bundle.c - use stream buffered input for rev-list git-bundle create on cygwin was nearly unusable due to 1 character at a time (unbuffered) reading from an exec'ed process. Fix by using fdopen to get a buffered stream. Results for "time git bundle create test.bdl v1.0.3..v1.5.2" are: before this patch: cygwin linux real 1m38.828s 0m3.578s user 0m12.122s 0m2.896s sys 1m28.215s 0m0.692s after this patch: real 0m3.688s 0m2.835s user 0m3.075s 0m2.731s sys 0m1.075s 0m0.149s Signed-off-by: Mark Levedahl <mdl123@verizon.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago

If you do: git bundle create v2.6-20-v2.6.22.bndl v2.6.20..v2.6.22 the bundle records that it requires v2.6.20^0 commit (correct) and gives you tag v2.6.22 (incorrect); the bug is that the object it lists in fact is the commit v2.6.22^0, not the tag. This is because the revision range operation .. is always about set of commits, but the code near where my patch touches does not validate that the sha1 value obtained from dwim_ref() against the commit object name e->item->sha1 before placing the head information in the commit. The attached patch attempts to fix this problem. Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Junio C Hamano	7fa8254f94	allow git-bundle to create bottomless bundle While "git bundle" was a useful way to sneakernet incremental changes, we did not allow: $ git bundle create v2.6.20.bndl v2.6.20 to create a bundle that contains the whole history to a well-known good revision. Such a bundle can be mirrored everywhere, and people can prime their repository with it to reduce the load on the repository that serves near the tip of the development.

Johan Herland	8a912bcb25	Ensure return value from xread() is always stored into an ssize_t This patch fixes all calls to xread() where the return value is not stored into an ssize_t. The patch should not have any effect whatsoever, other than putting better/more appropriate type names on variables.

Theodore Ts'o	46efd2d93c	Rename warn() to warning() to fix symbol conflicts on BSD and Mac OS This fixes a problem reported by Randal Schwartz: >I finally tracked down all the (albeit inconsequential) errors I was getting >on both OpenBSD and OSX. It's the warn() function in usage.c. There's >warn(3) in BSD-style distros. It'd take a "great rename" to change it, but if >someone with better C skills than I have could do that, my linker and I would >appreciate it. It was annoying to me, too, when I was doing some mergetool testing on Mac OS X, so here's a fix. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: "Randal L.

Shawn O. Pearce	b1daf300d0	Replace fork_with_pipe in bundle with run_command Now that the run_command family supports all of the redirection modes needed by builtin-bundle, we can use those functions rather than the underlying POSIX primitives. This should help to make the bundle command slightly more portable to other systems, like Windows. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Johannes Schindelin	34572ed2c8	git-bundle: only die if pack would be empty, warn if ref is skipped A use case for git-bundle expected to be quite common is this: $ git bundle create daily.bundle --since=10.days.ago --all The expected outcome is _not_ to error out if only a couple of the refs were not changed during the last 10 days. This patch complains loudly about refs which are skipped due to the pack not containing the corresponding objects, but dies only if no objects would be in the pack _at all_.

Johannes Schindelin	2e578f9a4f	git-bundle: prevent overwriting existing bundles Not only does it prevent accidentally losing older bundles, but it also fixes a subtle bug: when writing into an existing bundle, git-pack-objects would not truncate the bundle. Therefore, fetching from the bundle would trigger an error in unpack-objects: "fatal: pack has junk at the end".

Johannes Schindelin	d58c6184e3	git-bundle: die if a given ref is not included in bundle The earlier patch tried to be nice by just warning, but it seems more likely that the user wants to adjust the parameters. Also, it prevents a bundle containing _all_ revisions in the case when the user only gave one ref, but also rev-list options which excluded the ref.

Johannes Schindelin	263703fff3	git-bundle: handle thin packs in subcommand "unbundle" The patch to make the packs in a bundle thin forgot the receiving side. D'oh. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Johannes Schindelin	9e64d109f9	git-bundle: Make thin packs Thin packs are way smaller, but they rely on the receiving end to have the base objects. However, Git's pack protocol also uses thin packs by default. So make the packs contained in bundles thin, since bundles are just another transport. The patch looks a bit bigger than intended, mainly because --thin _implies_ that pack-objects should run its own rev-list. Therefore, this patch removes all the stuff we used to roll rev-list ourselves. This commit also changes behaviour slightly: since we now know early enough if a specified ref is _not_ contained in the pack, we can avoid putting that ref into the pack. So, we don't die() here, but warn() instead, and skip that ref. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Johannes Schindelin	18449ab0e9	git-bundle: avoid packing objects which are in the prerequisites When saying something like "--since=1.day.ago" or "--max-count=5", git-bundle finds the boundary commits which are recorded as prerequisites. However, it failed to tell pack-objects _not_ to pack the objects which are in these. Fix that. And add a test for that.

Johannes Schindelin	8315588b59	bundle: fix wrong check of read_header()'s return value & add tests If read_header() fails, it returns <0, not 0. Further, an open(/dev/null) was not checked for errors. Also, this adds two tests to make sure that the bundle file looks correct, by checking if it has the header has the expected form, and that the pack contains the right amount of objects.

Junio C Hamano	80e25ceece	git-bundle: make verify a bit more chatty. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	c2dea5a11c	git-bundle: various fixups verify_bundle() returned with an error early only when all prerequisite commits were missing. It should error out much earlier when some are missing. When the rev-list is limited in ways other than revision range (e.g. --max-count or --max-age), create_bundle() listed all positive refs given from the command line as if they are available, but resulting pack may not have some of them. Add a logic to make sure all of them are included, and error out otherwise. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	2b064697a5	revision traversal: retire BOUNDARY_SHOW This removes the flag internally used by revision traversal to decide which commits are indeed boundaries and renames it to CHILD_SHOWN. builtin-bundle uses the symbol for its verification, but I think the logic it uses it is wrong. The flag is still useful but it is local to the git-bundle, so it is renamed to PREREQ_MARK. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	c044aa18f6	git-bundle: fix pack generation. The handcrafted built-in rev-list lookalike forgot to mark the trees and blobs contained in the boundary commits uninteresting, resulting in unnecessary objects in the pack. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago

Johannes Schindelin	fa257b0554	git-bundle: assorted fixes This patch fixes issues mentioned by Junio, Nico and Simon: - I forgot to convert the usage string when removing the "--" from the subcommands, - a style fix in the bundle_header, - use xread() instead of read(), - use write_or_die() instead of write(), - make the bundle header extensible, - fail if the whitespace after a sha1 of a reference is missing, - close() the fds passed to a subprocess, - in verify_bundle(), do not use "rev-list --stdin", but rather pass the revs directly (avoiding a fork()), - fix a corrupted comment in show_object(), and - fix the size check in index_pack.

Johannes Schindelin	2e0afafebd	Add git-bundle: move objects and references by archive Some workflows require use of repositories on machines that cannot be connected, preventing use of git-fetch / git-push to transport objects and references between the repositories. git-bundle provides an alternate transport mechanism, effectively allowing git-fetch and git-pull to operate using sneakernet transport. `git-bundle create` allows the user to create a bundle containing one or more branches or tags, but with specified basis assumed to exist on the target repository. At the receiving end, git-bundle acts like git-fetch-pack, allowing the user to invoke git-fetch or git-pull using the bundle file as the URL. git-fetch and git-ls-remote determine they have a bundle URL by checking that the URL points to a file, but are otherwise unchanged in operation with bundles. The original patch was done by Mark Levedahl <mdl123@verizon.net>. It was updated to make git-bundle a builtin, and get rid of the tar format: now, the first line is supposed to say "# v2 git bundle", the next lines either contain a prerequisite ("-" followed by the hash of the needed commit), or a ref (the hash of a commit, followed by the name of the ref), and finally the pack. As a result, the bundle argument can be "-" now. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
