The Audiobookshelf logs sometimes contain information about the source
of the log statement, but sometimes they don't This really depends on
developers adding these information to the log messages.
But even then, the information is usually just a hint about the module
logging this, like `[Db]` or [Watcher]`, and finding the exact line can
be hard.
This patch automatically adds the source of the log statement to the
logs. This means if someone calls `Logger.info(…)` in line `22` of
`foo.js`, the log statement will contain this file and line:
```
[2023-01-05 19:04:12[ (LogManager.js:85:18) DEBUG: Daily Log file found 2023-01-05.txt
[2023-01-05 19:04:12] (LogManager.js:59:12) INFO: [LogManager] Init current daily log filename: 2023-01-05.txt
```
This should make it much easier to identify the code where the log
statement originated from.
Long-term, this also means that we can probably remove the manually set
identifiers contained in the log messages, like the `[LogManager]` in
the example above.
If the scanner detects new files with a path containing part of the name
of an already existing library item, the new item will incorrectly be
detected as being a parent directory of the already existing item and
the import will be aborted.
You can follow these steps to reproduce the issue:
```
❯ mkdir audiobooks/author/
❯ mv title\ 10 audiobooks/author
[2022-12-18 22:14:12] DEBUG: [Watcher] File Added /home/lars/dev/audiobookshelf/audiobooks/author/title 10/dictaphone.mp3
[2022-12-18 22:14:16] DEBUG: [DB] Library Items inserted 1
❯ mv title\ 1 audiobooks/author
[2022-12-18 22:15:03] DEBUG: [Watcher] File Added /home/lars/dev/audiobookshelf/audiobooks/author/title 1/dictaphone.mp3
[2022-12-18 22:15:07] WARN: [Scanner] Files were modified in a parent directory of a library item "title 10" - ignoring
```
Since `'title 10'.startsWith('title 1')` is `true`, the current code
makes this false assumption.
This patch fixes the issue by requiring a path separator to be part of
the matching path. This should ensure that only true parent directories
are detected.
This patch requires audiobookshelf to always use Unix file separators.
But that shouldn't be a problem since audiobookshelf always seems to use
these kinds of separators. Even on Windows.
