This change adds a child logger with request information to the
http request context. Also improved the log format for clarity.
- Unescaped the query string
- Use JSON log format when not in dev mode.
- Added request ip to the request child logger.
- The child logger is passed to the converter so we can associate
any errors with a specific request / file.
- Add book file name as a logger attribute
- Add user agent header as a logger attribute
- Log the "X-Forwarded-For" header, falling back to RemoteAddr
See the notes for a full explanation, but basically
Kobo is making simultaneous requests and the
files were conflicting because there were 2 being
downloaded / converted at the same time which
resulted in unreliable behavior.
The solution is to protect the conversion
section to allow a single conversion to complete
before allowing the next one to start.
Working *.epub to *.kepub.epub file conversions when
using a Kobo reader. Updated docker file to include
`kepubify` to convert to kepub. If not available the
file is just sent without conversion.
