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.
This commit fixes a nasty bug, where the docker-entrypoint.sh silently
exits without any error message. The test for a lock file can fail and
due to the `set -e` at the beginning of the file the bash script exists
without starting the paperless application.
It is fixed by moving the check for the existence of the lock file into
the if statement, where the `set -e` does not trigger an exit in case
the statement fails.
Additionally this commit enables the script to trap exit signals and in
that case deletes the lock file.
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.
