2011-03-16standardize brace placement in struct definitionsLibravatar Jonathan Nieder1-28/+14
In a struct definitions, unlike functions, the prevailing style is for the opening brace to go on the same line as the struct name, like so: struct foo { int bar; char *baz; }; Indeed, grepping for 'struct [a-z_]* {$' yields about 5 times as many matches as 'struct [a-z_]*$'.

If a pack file is small enough that its entire contents fits within one mmap window, mmap the file and then immediately close its file descriptor. This reduces the number of file descriptors that are needed to read from repositories with many tiny pack files, such as one that has received 1000 pushes (and created 1000 small pack files) since its last repack.

2011-02-26fast-import: add 'ls' commandLibravatar David Barr1-3/+159
Lazy fast-import frontend authors that want to rely on the backend to keep track of the content of the imported trees _almost_ have what they need in the 'cat-blob' command (v1.7.4-rc0~30^2~3, 2010-11-28). But it is not quite enough, since (1) cat-blob can be used to retrieve the content of files, but not their mode, and (2) using cat-blob requires the frontend to keep track of a name (mark number or object id) for each blob to be retrieved Introduce an 'ls' command to complement cat-blob and take care of the remaining needs. The 'ls' command finds what is at a given path within a given tree-ish (tag, commit, or tree): 'ls' SP <dataref> SP <path> LF or in fast-import's active commit: 'ls' SP <path> LF The response is a single line sent through the cat-blob channel, imitating ls-tree output. So for example: FE> ls :1 Documentation gfi> 040000 tree 9e6c2b599341d28a2a375f8207507e0a2a627fe9 Documentation FE> ls 9e6c2b599341d28a2a375f8207507e0a2a627fe9 git-fast-import.txt gfi> 100644 blob 4f92954396e3f0f97e75b6838a5635b583708870 git-fast-import.txt FE> ls :1 RelNotes gfi> 120000 blob b942e499449d97aeb50c73ca2bdc1c6e6d528743 RelNotes FE> cat-blob b942e499449d97aeb50c73ca2bdc1c6e6d528743 gfi> b942e499449d97aeb50c73ca2bdc1c6e6d528743 blob 32 gfi> Documentation/RelNotes/1.7.4.txt The most interesting parts of the reply are the first word, which is a 6-digit octal mode (regular file, executable, symlink, directory, or submodule), and the part from the second space to the tab, which is a <dataref> that can be used in later cat-blob, ls, and filemodify (M) commands to refer to the content (blob, tree, or commit) at that path. If there is nothing there, the response is "missing some/path". The intent is for this command to be used to read files from the active commit, so a frontend can apply patches to them, and to copy files and directories from previous revisions. For example, proposed updates to svn-fe use this command in place of its internal representation of the repository directory structure. This simplifies the frontend a great deal and means support for resuming an import in a separate fast-import run (i.e., incremental import) is basically free.

2011-02-09fast-import: introduce "feature notes" commandLibravatar Jonathan Nieder1-0/+2
Here is a 'feature' command for streams to use to require support for the notemodify (N) command. When the 'feature' facility was introduced (v1.7.0-rc0~95^2~4, 2009-12-04), the notes import feature was old news (v1.6.6-rc0~21^2~8, 2009-10-09) and it was not obvious it deserved to be a named feature. But now that is clear, since all major non-git fast-import backends lack support for it. Details: on git version with this patch applied, any "feature notes" command in the features/options section at the beginning of a stream will be treated as a no-op. On fast-import implementations without the feature (and older git versions), the command instead errors out with a message like This version of fast-import does not support feature notes. So by declaring use of notes at the beginning of a stream, frontends can avoid wasting time and other resources when the backend does not support notes. (This would be especially important for backends that do not support rewinding history after a botched import.)

2011-01-27fast-import: treat filemodify with empty tree as deleteLibravatar Jonathan Nieder1-0/+6
Normal git processes do not allow one to build a tree with an empty subtree entry without trying hard at it. This is in keeping with the general UI philosophy: git tracks content, not empty directories. v1.7.3-rc0~75^2 (2010-06-30) changed that by making it easy to include an empty subtree in fast-import's active commit: M 040000 4b825dc642cb6eb9a060e54bf8d69288fbee4904 subdir One can trigger this by reading an empty tree (for example, the tree corresponding to an empty root commit) and trying to move it to a subtree. It is better and more closely analogous to 'git read-tree --prefix' to treat such commands as requests to remove the subtree.

2011-01-18fast-import: Introduce --import-marks-if-existsLibravatar Ramkumar Ramachandra1-3/+13
When a frontend uses a marks file to ensure its state persists between runs, it may represent "clean slate" when bootstrapping with "no marks yet". In such a case, feeding the last state with --import-marks and saving the state after the current run with --export-marks would be a natural thing to do. The --import-marks option however errors out when the specified marks file doesn't exist; this makes bootstrapping a bit difficult. The location of the marks file becomes backend-dependent when --relative-marks is in effect, and the frontend cannot check for the existence of the file in such a case. The --import-marks-if-exists option does the same thing as --import-marks but does not flag an error if the named file does not exist yet to help these frontends.

The new rule: a "cat-blob" can be inserted wherever a comment is allowed, which means at the start of any line except in the middle of a "data" command.

2010-12-01fast-import: let importers retrieve blobsLibravatar David Barr1-0/+97
New objects written by fast-import are not available immediately. Until a checkpoint has been started and finishes writing the pack index, any new blobs will not be accessible using standard git tools. So introduce a new way to access them: a "cat-blob" command in the command stream requests for fast-import to print a blob to stdout or a file descriptor specified by the argument to --cat-blob-fd. The value for cat-blob-fd cannot be specified in the stream because that would be a layering violation: the decision of where to direct a stream has to be made when fast-import is started anyway, so we might as well make the stream format is independent of that detail. Output uses the same format as "git cat-file --batch". Thanks to Sverre Rabbelier and Sam Vilain for guidance in designing the protocol.

2010-11-24fast-import: treat SIGUSR1 as a request to access objects earlyLibravatar Jonathan Nieder1-1/+40
It can be tedious to wait for a multi-million-revision import. Unfortunately it is hard to spy on the import because fast-import works by continuously streaming out objects, without updating the pack index or refs until a checkpoint command or the end of the stream. So allow the impatient operator to request checkpoints by sending a signal, like so: killall -USR1 git-fast-import When receiving such a signal, fast-import would schedule a checkpoint to take place after the current top-level command (usually a "commit" or "blob" request) finishes. Caveats: just like ordinary checkpoint commands, such requests slow down the import. Switching to a new pack at a suboptimal moment is also likely to result in a less dense initial collection of packs. That's the price.

But it went too far. In change_note_fanout(), an empty, not-loaded tree is not meant to destroy notes, so calling load_tree() at that point is exactly the wrong thing to do.

And as a side-effect of 2794ad5 (fast-import: Allow filemodify to set the root, 2010-10-10), this last call is accepted and changes the tree entry for root:foo/bar to refer to the specified tree.

v1.7.3-rc0~75^2 (Teach fast-import to import subtrees named by tree id, 2010-06-30) has a shortcoming - it doesn't allow the root to be set. Extend this behaviour by allowing the root to be referenced as the empty path, "". For a command (like filter-branch --subdirectory-filter) that wants to commit a lot of trees that already exist in the object db, writing undeltified objects as loose files only to repack them later can involve a significant amount of overhead. (23% slow-down observed on Linux 2.6.35, worse on Mac OS X 10.6) Fortunately we have fast-import (which is one of the only git commands that will write to a pack directly) but there is not an advertised way to tell fast-import to commit a given tree without unpacking it. This patch changes that, by allowing M 040000 <tree id> "" as a filemodify line in a commit to reset to a particular tree without any need to parse it. For example, M 040000 4b825dc642cb6eb9a060e54bf8d69288fbee4904 "" is a synonym for the deleteall command and the fast-import equivalent of git read-tree 4b825dc642cb6eb9a060e54bf8d69288fbee4904 Signed-off-by: David Barr <david.barr@cordelta.com> Commit-message-by: Jonathan Nieder <jrnieder@gmail.com> Acked-by: Sverre Rabbelier <srabbelier@gmail.com> Tested-by: Ramkumar Ramachandra <artagnon@gmail.com> Signed-off-by: Ramkumar Ramachandra <artagnon@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-07-09fast-import: Improve robustness when D->F changes provided in wrong orderLibravatar Elijah Newren1-0/+8
When older versions of fast-export came across a directory changing to a symlink (or regular file), it would output the changes in the form M 120000 :239821 dir-changing-to-symlink D dir-changing-to-symlink/filename1 When fast-import sees the first line, it deletes the directory named dir-changing-to-symlink (and any files below it) and creates a symlink in its place. When fast-import came across the second line, it was previously trying to remove the file and relevant leading directories in tree_content_remove(), and as a side effect it would delete the symlink that was just created. This resulted in the symlink silently missing from the resulting repository. To improve robustness, we ignore file deletions underneath directory names that correspond to non-directories. This can also be viewed as a minor optimization: since there cannot be a file and a directory with the same name in the same directory, the file clearly can't exist so nothing needs to be done to delete it.

The following function is duplicated: encode_header Move this function to sha1_file.c and rename it 'encode_in_pack_object_header', as suggested by Junio C Hamano Signed-off-by: Michael Lukashov <michael.lukashov@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-02-17fast-import: use the diff_delta() max_delta_size argumentLibravatar Nicolas Pitre1-6/+2
This let diff_delta() abort early if it is going to bust the given size limit. Also, only objects larger than 20 bytes are considered as objects smaller than that are most certainly going to produce larger deltas than the original object due to the additional headers.

2010-02-17fast-import: make default pack size unlimitedLibravatar Nicolas Pitre1-6/+6
Now that fast-import is creating packs with index version 2, there is no point limiting the pack size by default. A pack split will still happen if off_t is not sufficiently large to hold large offsets. While updating the doc, let's remove the "packfiles fit on CDs" suggestion. Pack files created by fast-import are still suboptimal and a 'git repack -a -f -d' or even 'git gc --aggressive' would be a pretty good idea before considering storage on CDs.

2010-02-17fast-import: use write_idx_file() instead of custom codeLibravatar Nicolas Pitre1-46/+17
This allows for the creation of pack index version 2 with its object CRC and the possibility for a pack to be larger than 4 GB. Signed-off-by: Nicolas Pitre <nico@fluxnic.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-02-17fast-import: use sha1write() for pack dataLibravatar Nicolas Pitre1-10/+25
This is in preparation for using write_idx_file(). Also, by using sha1write() we get some buffering to reduces the number of write syscalls, and the written data is SHA1 summed which allows for the extra data integrity validation check performed in fixup_pack_header_footer() (details on this in commit abeb40e5aa).

2010-02-04fast-import: count --max-pack-size in bytesLibravatar Junio C Hamano1-6/+11
Similar in spirit to 07cf0f2 (make --max-pack-size argument to 'git pack-object' count in bytes, 2010-02-03) which made the option by the same name to pack-objects, this counts the pack size limit in bytes. In order not to cause havoc with people used to the previous megabyte scale an integer smaller than 8192 is interpreted in megabytes but the user gets a warning. Also a minimum size of 1 MiB is enforced to avoid an explosion of pack files. Signed-off-by: Junio C Hamano <gitster@pobox.com> Acked-by: Shawn O.

Manual merge made at 844ad3d (Merge branch 'sp/maint-fast-import-large-blob' into sp/fast-import-large-blob, 2010-02-01) did not correctly reflect the change of unit in which this variable's value is counted from its previous version. Now it counts in bytes, not in megabytes. Signed-off-by: Junio C Hamano <gitster@pobox.com> Acked-by: Shawn O. Pearce <spearce@spearce.org>
