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

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.

If a blob is larger than the configured big-file-threshold, instead of reading it into a single buffer obtained from malloc, stream it onto the end of the current pack file. Streaming the larger objects into the pack avoids the 4+ GiB memory footprint that occurs when fast-import is processing 2+ GiB blobs. Signed-off-by: Shawn O.

2010-01-14fast-import: tag may point to any object typeLibravatar Dmitry Potapov1-5/+5
If you tried to export the official git repository, and then to import it back then git-fast-import would die complaining that "Mark :1 not a commit". Accordingly to a generated crash file, Mark 1 is not a commit but a blob, which is pointed by junio-gpg-pub tag. Because git-tag allows to create such tags, git-fast-import should import them.

2009-12-31fast-import: Document author/committer/tagger name is optionalLibravatar Shawn O. Pearce1-3/+3

2009-12-07fast-import: Proper notes tree manipulationLibravatar Johan Herland1-5/+129
This patch teaches 'git fast-import' to automatically organize note objects in a fast-import stream into an appropriate fanout structure. The notes API in notes.h is NOT used to accomplish this, because trying to keep the fast-import and notes data structures in sync would yield a significantly larger patch with higher complexity. Note objects are added with the 'N' command, and accounted for with a per-branch counter, which is used to trigger fanout restructuring when needed. Note that when restructuring the branch tree, _any_ entry whose path consists of 40 hex chars (not including directory separators) will be recognized as a note object. It is therefore not advisable to manipulate note entries with M/D/R/C commands. Since note objects are stored in the same tree structure as other objects, the unloading and reloading of a fast-import branches handle note objects transparently.

2009-12-05fast-import: add (non-)relative-marks featureLibravatar Sverre Rabbelier1-2/+17
After specifying 'feature relative-marks' the paths specified with 'feature import-marks' and 'feature export-marks' are relative to an internal directory in the current repository. In git-fast-import this means that the paths are relative to the '.git/info/fast-import' directory. However, other importers may use a different location. Add 'feature non-relative-marks' to disable this behavior, this way it is possible to, for example, specify the import-marks location as relative, and the export-marks location as non-relative. Also add tests to verify this behavior. Cc: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Sverre Rabbelier <srabbelier@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-12-04fast-import: allow for multiple --import-marks= argumentsLibravatar Sverre Rabbelier1-5/+16
The --import-marks= option may be specified multiple times on the commandline and should result in all marks being read in. Only one import-marks feature may be specified in the stream, which is overriden by any --import-marks= commandline options. If one wishes to specify import-marks files in addition to the one specified in the stream, it is easy to repeat the stream option as a --import-marks= commandline option. Also verify this behavior with tests. Signed-off-by: Sverre Rabbelier <srabbelier@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-12-04fast-import: add option commandLibravatar Sverre Rabbelier1-25/+62
This allows the frontend to specify any of the supported options as long as no non-option command has been given. This way the user does not have to include any frontend-specific options, but instead she can rely on the frontend to tell fast-import what it needs. Also factor out parsing of argv and have it execute when we reach the first non-option command, or after all commands have been read and no non-option command has been encountered. Non-git options are ignored, unrecognised options result in an error. Signed-off-by: Sverre Rabbelier <srabbelier@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-10-19fast-import: Add support for importing commit notesLibravatar Johan Herland1-4/+84
Introduce a 'notemodify' subcommand of the 'commit' command. This subcommand is similar to 'filemodify', except that no mode is supplied (all notes have mode 0644), and the path is set to the hex SHA1 of the given "comittish". This enables fast import of note objects along with their associated commits, since the notes can now be named using the mark references of their corresponding commits.

* jc/maint-1.6.0-pack-directory: Make sure objects/pack exists before creating a new pack
2009-02-25Make sure objects/pack exists before creating a new packLibravatar Junio C Hamano1-9/+5
In a repository created with git older than f49fb35 (git-init-db: create "pack" subdirectory under objects, 2005-06-27), objects/pack/ directory is not created upon initialization. It was Ok because subdirectories are created as needed inside directories init-db creates, and back then, packfiles were recent invention. After the said commit, new codepaths started relying on the presense of objects/pack/ directory in the repository. This was exacerbated with 8b4eb6b (Do not perform cross-directory renames when creating packs, 2008-09-22) that moved the location temporary pack files are created from objects/ directory to objects/pack/ directory, because moving temporary to the final location was done carefully with lazy leading directory creation. Many packfile related operations in such an old repository can fail mysteriously because of this. This commit introduces two helper functions to make things work better. - odb_mkstemp() is a specialized version of mkstemp() to refactor the code and teach it to create leading directories as needed; - odb_pack_keep() refactors the code to create a ".keep" file while create leading directories as needed.
