versionvfs.tcl --
Written by Stephen Huntley (stephen.huntley@alum.mit.edu)
License: Tcl license
Version 1.5.2
A versioning virtual filesystem. Requires the template vfs in templatevfs.tcl.
Similar to historical versioning filesystems, each edited version of a file is saved separately;
each version file is tagged with a timestamp, and optional project tags.
A deleted file is represented by a new zero-length file with timestamp and a tag reading "deleted".
By default only the latest version is visible. If the latest version is marked deleted, it is invisible.
Directories are versioned and tagged in the same way as files.
Older versions can be retrieved by setting the -project and -time values appropriately.
Usage: mount ?-keep <number> -project <list of tags> -time <timestamp or "clock scan" suitable phrase>? <existing directory> <virtual directory>
Options:
-keep
maximum number of previous versions of a file to keep per project.
-project
a list of one or more version-identifying tags. Any file created or edited in the virtual file space
will be given these tags. File versions with a tag matching the ones given here will be visible in
preference to other, possibly later versions without the tag.
If a file version has project tags but none of them is included in this project tag list, it will be
invisible; the file itself will then be invisible unless a file version exists without any
project tags, in which case it will be treated as the default.
In cases where several file versions each have multiple tags that match in the project
list, the version with the greatest number of matches will be visible.
Deleted files are marked with the tag "deleted". If this value is in the project
name list, then deleted files will become visible again.
Newly-created and deleted directories are tagged and shown/hidden in the same way as files.
-time
A timestamp in the form returned by [clock seconds], or a string understandable by [clock scan].
Versions of files as they existed at the given time will be visible, rather than the
default latest version. Version choices based on project tags will still be made, but
versions later than the timestamp will be ignored in the decision process.
The values of each option can be changed dynamically after mount by using the "file attributes"
command on the mount virtual directory. Each option is editable as an attribute;
i.e., "file attributes C:/version -project {version2 release}". Display of visible files will
change dynamically based on decisions with new attribute values.
In addition, new attributes are defined which can be queried for individual files:
The command "file attributes $file -version_filename" will show the exact filename of the
currently visible version of the given file as it is stored in the vfs, complete with
timestamp and project tags if any.
The command "file attributes $file -versions" will return a list containing information on
all stored versions of the given file. Each element of the list is itself a three-element
list: 1) the unique millisecond-level timestamp of the version, 2) a human-readable date string
showing the time represented by the timestamp (can be used a a value for the -time attribute),
and 3) a list of the project tags attached to the version, if any.
The versioning vfs inherits the -cache and -volume options of the template vfs.
