More work to get large tiddler PUT and DELETE to be more efficient when using tiddlywebplugins.sqlalchemy3.

Wrote to google groups about binary tiddlers in tiddlyweb.

Looks like the country might deserve an asbo on the jubilee.

I looked into updating nodejs on tiddlyspace.com to see if it would address problems with twikifier but discovered that I couldn't update node without updating a bunch of the npm installed modules: Changes in APIs. Given the time constraints this evening that was more than I was willing to contemplate, so some other time. It does point out, however, that both twikifier and twsock need to be packaged in a way that allows for easy deployment (like TiddlySpace itself).

Spent some time experimenting with allowing the text attribute of a Tiddler object to be a file object to see if this might be more efficient when dealing with binary tiddlers. Unfortunately the change does not address the recently raised JSON PUT of binary data issue.

To address both the incoming HTTP socket's filehandle needs to be carried around throughout the current request. This could allow binary content to be written straight to disk from the socket, without going into RAM.

However, getting this to work without making changes throughout StorageInterfaces and Serializations is likely hard. Of course that's speculation. It could be spectacularly easy, but the concern is to not impact existing code too much.

Perhaps a Tiddler subclass could be useful? More poking required.

At the same time I did some analysis on the sqlalchemy code to see if I could locate where problems with PUT and DELETE may be coming from. For DELETE there were issues with loading too many objects into the session. Still unclear on PUT.

Had a BT hothouse for the past few days. Made some tiddler related tools that are pretty cool. Once awake again, will have to dig them out of the cruft and show them off to the world. Mostly fun with html5™ type things.
