New submission from Garrett Nievin:
Using Claws Mail, and mailbox.MH crashes on two different conditions:
1) sequence spans lines, suchly:
unseen: 1-222 225-300
990-1024 1048-2048
Not Pythonic, but I fixed it with this update:
def get_sequences(self):
"""Return a name-to-key-list dictionary to define each sequence."""
results = {}
with open(os.path.join(self._path, '.mh_sequences'), 'r', encoding='ASCII') as f:
all_keys = set(self.keys())
for line in f:
try:
if line.count(':') == 0:
contents = line
else:
name, contents = line.split(':')
keys = set()
for spec in contents.split():
if spec.isdigit():
keys.add(int(spec))
2) Sequence spec appears to be open-ended on the front:
28119-28123 28127 28129 28131 28133-28142 28144-28154 28156-28172 28174-28189 28191-28204 28206-28218 28220-28224 28226 28228-28234 28237-28239
28119-28123 28127 28129 28131 28133-28142 28144-28154 28156-28163
28119-28123 28127 28129 28131 28133-28157
-27920 27923-27945 27947
I'm not sure how to interpret this, so just put in a kludgy fix to get my script running as a workaround (not using sequences).
Would also be interested in an option to open a mailbox and process while ignoring sequences.
