1. Fail when the db contains encrypted docs and no password is set.
Previously, this case wasn't detected.
2. Exit with an error instead of showing warnings.
This ensures that we never store docs with different encryption passwords.
1. Clicks to the document selection checkbox were captured by the onclick
handler of the document item header. This is now fixed.
2. Reexpose the doc title link to mouse events by putting it on top of
the header link layer.
This allows for future decisions around the types of encryption used (if any). Ideally, I want to replace GPG one day with something elegant out of the cryptography module.
Make the sleep duration dynamic to account for the time spent in
loop_step.
This improves responsiveness when repeatedly consuming newly
arriving docs.
Use float epoch seconds (time.time()) as the time type for
MailFetcher.last_checked to allow for natural time arithmetic.
Renamings:
loop -> loop_step
delta -> next_mail_time (this variable names a point in time, not a duration)
Extracting the 'loop' fn is a preparation for later commits where a
second type of loop is added.
1. Store the mtime of ignored files so that we can reconsider them if
they have changed.
2. Regularly reset the ignore list to files that still exist in the
consumption dir. Previously, the list could grow indefinitely.
Previously, the second mtime check for new files usually happened right
after the first one, which could have caused consumption of docs that
were still being modified.
We're now waiting for at least FILES_MIN_UNMODIFIED_DURATION (0.5s).
This also cleans up the logic by eliminating the consumer.stats attribute
and the weird double call to consumer.run().
Additionally, this a fixes memory leak in consumer.stats where paths could be
added but never removed if the corresponding files disappeared from
the consumer dir before being considered ready.
