Expected behaviour

Close files that aren't in use / have a settable limit

Actual behaviour

Every database file it opens stays open for the duration of the sync

Steps to re

Whiskers' regex looks for <..> as opposed to tokenizing the input, so it is not able to detect truncated/mistyped input.

For example it can't detect that <!b is not terminated in<?b> X <!b Y </b>.

With some heuristics it could be improved: match for <?, <! and </ and only allow identifiers which are terminated with >, otherwise it is invalid.

Issue

Tests are not isolated from each other. I reproduced it using the metacoin box tutorial, adding a new test at the end that checks again the balance. As per the "clean-room" the first account should have all 10000 tokens. It's not.
