Michael Vrable [Fri, 11 May 2007 05:10:26 +0000 (22:10 -0700)]
Add a new object-oriented wrapper for building object references.
Michael Vrable [Fri, 11 May 2007 00:43:00 +0000 (17:43 -0700)]
Miscellaneous changes.
- Disable profiling output for now. It can be turned on again later.
- Allow destination directory for backup files to be specified on the
command-line (but we should add proper command-line parsing later).
- More work to track inter-object references, but not yet finished.
Michael Vrable [Thu, 3 May 2007 22:56:04 +0000 (15:56 -0700)]
Start work on a more object-oriented interface for creating objects.
Michael Vrable [Thu, 3 May 2007 22:13:21 +0000 (15:13 -0700)]
Rename tarstore -> store, since it is the only implementation now.
Michael Vrable [Thu, 3 May 2007 22:03:19 +0000 (15:03 -0700)]
Remove old store implementation.
Michael Vrable [Thu, 3 May 2007 21:23:21 +0000 (14:23 -0700)]
Partial support for tracker inter-object references.
Michael Vrable [Wed, 25 Apr 2007 05:46:42 +0000 (22:46 -0700)]
Add indrect objects for listing contents of large files.
Michael Vrable [Mon, 23 Apr 2007 04:41:25 +0000 (21:41 -0700)]
Remove code using old segment writer.
All writes should now happen to TAR-format segments, and data should be
serialized as text.
Michael Vrable [Mon, 23 Apr 2007 04:09:11 +0000 (21:09 -0700)]
Automatically split segments to meet size targets.
Michael Vrable [Sat, 21 Apr 2007 18:05:28 +0000 (11:05 -0700)]
Add URI-style escaping of filename characters.
Michael Vrable [Mon, 16 Apr 2007 04:56:33 +0000 (21:56 -0700)]
Remove early test code for the tarfile storage backend.
Michael Vrable [Mon, 16 Apr 2007 04:51:41 +0000 (21:51 -0700)]
Reduce debugging output.
Michael Vrable [Mon, 16 Apr 2007 04:34:07 +0000 (21:34 -0700)]
Add checksums to tarstore, and partially migrate to using it for storage.
Each tarfile segment gets a file called "checksums" now which contains
SHA-1 hashes of all objects contained in it. There is currently no
checksum computed for the checksum file itself.
Begin migrating scandir to using the tar-based storage for backups.
Backups in the old format are still written, and there is still some
other cleanup to be done, but most of the raw data is currently handled.
Michael Vrable [Sun, 15 Apr 2007 20:48:09 +0000 (13:48 -0700)]
Begin work on an alternate object store mechanism using the TAR format.
Each segment is placed in a separate file, and each object is a file stored
within that TAR archive. libtar is used to write (and perhaps later read)
tar files.
Michael Vrable [Wed, 7 Feb 2007 21:45:30 +0000 (13:45 -0800)]
Tag objects with a 4-byte type code.
Michael Vrable [Thu, 11 Jan 2007 22:47:41 +0000 (14:47 -0800)]
Return the names for allocated objects, and link file metaata to data.
Extend the interface for the new_object methods so that they can return the
segment UUID and object index for created objects. Then, use this to write
out links from the file metadata to the data blocks making up the file, via
an indirect block.
Michael Vrable [Sat, 30 Dec 2006 03:24:48 +0000 (19:24 -0800)]
Support for spreading objects across segments.
New segments are created automatically whenever an old segment becomes too
large (current limit is set at something over 1 MB, but this could be
adjusted).
Michael Vrable [Fri, 29 Dec 2006 19:49:20 +0000 (11:49 -0800)]
Append checksums to segments to allow some verification.
Michael Vrable [Mon, 25 Dec 2006 06:28:59 +0000 (22:28 -0800)]
Add new interface for creating new segments.
Michael Vrable [Sun, 24 Dec 2006 04:15:31 +0000 (20:15 -0800)]
Initial support for objects encapsulated into segments.
Michael Vrable [Sun, 24 Dec 2006 01:21:10 +0000 (17:21 -0800)]
Some Makefile improvements:
- (Mostly) automatic header dependency tracking.
- Use pkg-config to pull in dependencies for libuuid.
Michael Vrable [Sun, 24 Dec 2006 01:19:58 +0000 (17:19 -0800)]
Improve comments, and track number of bytes written to a stream.
Michael Vrable [Sat, 23 Dec 2006 20:46:19 +0000 (12:46 -0800)]
Compute SHA-1 checksums of regular files to be stored with index data.
Michael Vrable [Sat, 23 Dec 2006 19:58:18 +0000 (11:58 -0800)]
Clean up output while scanning directories.
Michael Vrable [Sat, 23 Dec 2006 06:53:06 +0000 (22:53 -0800)]
Extend basic support for serializing simple data types.
Add support for serializing integers, strings, and dictionaries. Then,
extend the directory scanner to output a summary of stat information for
each file/directory.
Michael Vrable [Wed, 20 Dec 2006 02:55:15 +0000 (18:55 -0800)]
Fill in a couple more details about a proposed file format.
Michael Vrable [Sat, 16 Dec 2006 07:32:15 +0000 (23:32 -0800)]
Begin work to document a proposed file format for backups.
Michael Vrable [Sat, 16 Dec 2006 05:24:37 +0000 (21:24 -0800)]
Add support for reading symlinks.
Michael Vrable [Wed, 13 Dec 2006 16:44:21 +0000 (08:44 -0800)]
Read contents of all regular files processed.
Michael Vrable [Tue, 12 Dec 2006 05:46:33 +0000 (21:46 -0800)]
More work on descending directory structure.
Improvements:
- Directory listings are processed in sorted order.
- Open regular files, but be very paranoid in doing so (try to avoid
danger from race conditions).
Michael Vrable [Sun, 10 Dec 2006 19:45:38 +0000 (11:45 -0800)]
Build with support for large files enabled.
