Happy Birthday, Marco!

Marco,

Happy 4th Birthday.

Love, Daddy

getting close …

We’re getting very close to releasing zmugfs 0.1, the read-only release. As you may recall on Monday I got zmugfs to show imgdata in nautilus.

But I could only get it to work if I used the thumbnail sized imgdata. In the read() method I was logging into smugmug, reading the thumbnail imgdata, logging out of smugmug, getting the imgdata via http GET, and returning. Well, this is crazy because read gets called multiple times with different offsets. So I ended up implementing the open() and release() methods. In the open, I get the imgdata (original size) via the smugmug api and store the imgdata in an image cache (an in memory dictionary). In the read method, it now respects the offset and size attributes by reading from the image cache. Then in the release method, I delete the entry from the image cache. I know not much of a cache. But it solved my problem. I’m putting the cache work off a bit, not sure how to approach that yet.

Next thing I wanted to try all of the command line utils (at least the ones I’ve used before) to see how they react to zmugfs. I was pleasantly surprised with the result.

command	result	comment
basename	SUCCESS
cat	SUCCESS
chgrp	FAILURE	chgrp method not implemented
chmod	FAILURE	chmod method not implemented
chown	FAILURE	chown method not implemented
cp from	SUCCESS	able to copy image from smugmug using zmugfs
cp to	FAILURE	mknod not implemented
file	SUCCESS	got appropriate file type
ln -s	SUCCESS	softlink created
ls	SUCCESS	listing appears correctly
mkdir	FAILURE	mkdir method not implemented
mv	FAILURE	copy part worked; unlink not implemented
rm	FAILURE	unlink not implemented
rmdir	FAILURE	rmdir not implemented
touch	FAILURE	setattr not implemented

From a readonly perspective, it is looking great. What’s left before a release you ask? Just a few things.

• packaging
  • write spec file
  • figure out setup.py
• design a logo
• move code to zmugtools for branding purposes
• work out image cache

That’s it, once I finish those things zmugfs 0.1 will be released out into the wild! I’m really excited as this is my first ever open source project. I’ve submitted patches to a few things, but never anything this extensive.
