Basic functionality being there, let's fuck it up and rewrite some bits! Here is what I'm not happy with, or what I want to add/improve:


Do you have a test suite set up? It would make things (like fucking up the API to make it easier to use) a little bit safer.

I can help with writing those tests if you like; when it comes to small C projects I would usually go for just some executable that links to the library and calls assert() a bunch.
It had tests at first, for internal functions (bencoding related mostly). Now that only the API is accessible I don't see the point for tests. What would the test do? Download a file, and checksum it? you'd depend on access to the network here. Another idea would be to use a local tracker, spawned for the tests. Not really helpful either...

I wanted to have tests at first, but the simplest way to test is to do it manually at this point.

But I must admit I suck at writing tests, so if you have an idea, please speak up! :)
Thanks again for opening your thoughts on this project to the community.

$ doas find / -type f -exec du -k {} + | sort -n | awk '
        expected += $1 / 8 + 1;  # with 8 kB per block

    END {
        print("current: " current);
        print("expected: " expected);
        print("ratio: " expected / current);
current: 332455
expected: 8928090
ratio: 26.855

About 27 times more inodes in my case.

$ df -kih
Filesystem     Size    Used   Avail Capacity iused   ifree  %iused  Mounted on
/dev/sd0k      298G   60.2G    223G    21%  160449 19580221    1%   /home

8928090 / 19580221 = 46%
currently used space = 21%

With a size of 8kB per block, with my current setup, I would run out of inodes before I run out of space. You are right. :-)
