not_title filter incorrectly excludes episodes when keyword appears later in the title
Summary
The not_title filter is excluding episodes even when the forbidden keyword
does NOT appear at the start of the title.
It behaves as if the regex were matching anywhere in the string, or as if the
filter logic itself were inverted.
In short: episodes that should be allowed are being skipped with
regexp mismatch even though they do not match the not_title pattern.
This makes it impossible to exclude only specific titles (e.g., Mass titles)
without unintentionally blocking legitimate content (e.g., homilies or sermons).
Examples
These titles should be excluded (match the regex):
- "Holy Mass — Tuesday"
- "The Holy Sacrifice of the Mass"
- "The Holy Mass (Latin)"
These should NOT be excluded, but Podsync still rejects them:
- "Homily: The Parable of the Good Samaritan"
- "Sermon — Love Your Enemies"
- "Reflection on Today’s Gospel"
Podsync version
- 2.7.1-b
- Also reproduced with 2.8.0
- Running on Linux (Raspberry Pi)
Configuration snippet
filters = { min_duration = 600, not_title = "(?i)^(holy mass|holy sacrifice|the holy)( |$)" }
I wrote a unit test to validate this and the logic appears to work correctly - titles starting with the pattern get excluded, and titles like Homily: ... or Sermon — ... are kept as expected.
This makes me think something else is skipping your episodes. Could you share your debug logs (--debug flag) and full config? Also note your config has min_duration = 600, so anything under 10 minutes gets filtered out too.
Description:
I'm trying to exclude videos that start with specific patterns using the not_title filter, but all videos are being skipped with "regexp mismatch" even though some should match the pattern and be downloaded.
Expected behavior:
Videos starting with "Santa Misa", "Santo Sacrificio", or "El Santo" should be excluded
Videos starting with "Homilia, " (even if followed by "Santo Sacrificio...") should be included
Videos longer than 600 seconds should be considered
Actual behavior: All videos are skipped with "skipping due to regexp mismatch" in the logs, resulting in "no episodes to download".

Additional context:
Podsync version: 2.8.0
I've tried various regex patterns including:
"(?i)^(santa misa|santo sacrificio|el santo)"
"(?i)^(santa misa|santo sacrificio|el santo).*"
'^(Santa Misa|Santo Sacrificio|El Santo)' (with single quotes)
All result in the same "regexp mismatch" for every video
