This commit removes Six as a dependency for Pelican, replacing the
relevant aliases with the proper Python 3 imports. It also removes
references to Python 2 logic that did not require Six.
Competing static site generators integrate the functionality of regenerating
content and serving it into their main executable. In pelican this
functionality used to be in an external script `develop_server.sh` which
resides in the blog base directory. This has the disadvantage that changes in
pelican can break the `develop_server.sh` scripts which will not automatically
be upgraded together with pelican by package managers. Thus, pelican should
integrate this functionality into its main executable.
To this end, this commit removes `develop_server.sh` and adds three command
line options to the pelican executable:
* `-l/--listen` starts the HTTP server (`-s/--serve` was already taken)
* `-p/--port` specifies the port to listen at
* `-b/--bind` specifies the IP to bind to
`--listen` and `--autoreload` can be used together to achieve the same
effect that other static site generators offer: Serve files via HTTP
while at the same time auto-generating the content.
Since the `develop_server.sh` script was removed, pelican-quickstart looses the
`develop` option.
Since the `develop_server.sh` script was removed, the Makefile looses the
`stopserver` target and the `devserver` target is replaced by running `pelican
-l` in the foreground.
Since pelican now offers the `--listen` option, the fabfile uses that instead
of starting the socketserver itself.
`fab serve` and `make devserver` use different HTTP Handlers and as a
result they behave differently. This makes sure `fab serve` also uses
the Handler defined in `pelican.server` in order to get rid of the
inconsistency.
This is helpful for mobile testing of Pelican sites by allowing
broadcasting on the local network. Using port 80 requires
running as root on most machines.
Old system was using manual string formatting for log messages.
This caused issues with common operations like exception logging
because often they need to be handled differently for Py2/Py3
compatibility. In order to unify the effort:
- All logging is changed to `logging.level(msg, arg1, arg2)` style.
- A `SafeLogger` is implemented to auto-decode exceptions properly
in the args (ref #1403).
- Custom formatters were overriding useful logging functionality
like traceback outputing (ref #1402). They are refactored to be
more transparent. Traceback information is provided in `--debug`
mode for `read_file` errors in generators.
- Formatters will now auto-format multiline log messages in order
to make them look related. Similarly, traceback will be formatted in
the same fashion.
- `pelican.log.LimitFilter` was (ab)using logging message which
would result in awkward syntax for argumented logging style. This
functionality is moved to `extra` keyword argument.
- Levels for errors that would result skipping a file (`read_file`)
changed from `warning` to `error` in order to make them stand out
among other logs.
- Small consistency changes to log messages (i.e. changing all
to start with an uppercase letter) and quality-of-life improvements
(some log messages were dumping raw object information).
The socket may remain in the TIME_WAIT state for some time after the
server shuts down, which prevents another instance of the server from
listening on the same port. This change allows the server to reuse the
address even when it's still waiting.
Fixes an intermittent devserver problem with directory urls
containing index.html (i.e. clean urls). It tries to send the
index.html file twice, resulting in a scrambled web page complete
with HTTP headers in the output, and sometimes Broken Pipe errors.
