This page presents user-supplied information, hence may be inaccurate in some details, or not necessarily reflect use patterns anticipated by the [incr tsdb()] developers. This page was initiated by FrancisBond; please feel free to make additions or corrections as you see fit. However, before revising this page, one should be reasonably confident of the information given being correct. Further, observe that [incr tsdb()] database internals can change over time. For a given database (i.e. profile), the database schema is defined by the file relations, which is part of the profile directory. To cope with differences in database versions over time, [incr tsdb()] will always support reading from older formats, while writing is typically limmited to current versions.

Compressing a Test Suite

The File|Compress menu compresses a profile by gzipping the files that contain the data (i.e. all files with non-zero size except relations). After being compressed [incr tsdb()] treats the data as read-only: you can still browse , analyse and compare, but cannot reparse or treebank. The status is set to ro (read-only). There is no way to undo this from inside [incr tsdb()]. If you wish to decompress then you must ungzip the files externally.

A quick way of compressing a profile in this way using a shell is (assuming you are in the profile):

 find . -size +0 -type f -not -name 'relations' -exec gzip {} \;
