This is pretty cool.

To use this put in the tracker's lib subdirectory (create if missing).

Then add at the top of
  from interceptor import interceptor_factory, GzipFileClass,

  # Make a message file class which compresses the content before storage.
  MessageFileClass =

  # Make a file class which only stores unique files.

then later in replace FileClass:

  # FileClass automatically gets this property in addition to the Class
  #   content = String()    [saved to disk in <tracker home>/db/files/]
  #   type = String()       [MIME type of the content, default 'text/plain']
  msg = MessageFileClass(db, "msg",
                author=Link("user", do_journal='no'),
                recipients=Multilink("user", do_journal='no'),

  file = DataFileClass(db, "file",

as shown above.

I have not found any issues with the gzip of messages. The gui
displays msg files on disk in both uncompressed (before schema change)
and compressed (after schema change).

Using "zcat db/fles/msgs/0/msgs3" will show the contents of the
compressed message.

DataFileClass is interesting but has the following UI issues:

   When attaching the same file with a different name, the
     new file doesn't show up. Understandable since it is already
     attached. However it just looks like nothing happened. It
     should raise a message saying that the file already exists
     attached to the ticket under the other name.

   Assume we have two files with the same contents: a.txt and b.txt.
     attach a.txt (designated file1) to issue1 first then attach b.txt
     to issue2.  On issue2, a link is added to file1 reusing the
     exiting uploaded file so only one copy is kept on disk. The
     filename displayed on issue2 however is a.txt (the name of the
     first file to be attached). Not sure how to solve this. This
     could allow data leakage. Also a reference in issue2 to "b.txt"
     will be confusing.

This certainly merits posting on the wiki and I think the compressed
file idea is great.

I wonder is something similar could be done for those people who want
to put files as blobs in the database.
