We currently just document the fact that convert.exe can interfere with finding
ImageMagick's convert binary. We can solve this with a config option easily once
confit is merged.
This also changes the line endings for fetchart.rst back to Unix.
`urllib.urlretrieve` was using the correct extension in most cases -- I think
when the URL ended with .jpg -- but not in every case. This was leading to files
named just "cover" and not "cover.jpg" or something else sensible. In
particular, proxied URLs don't have .jpg extensions. This generates the filename
manually so the source image always has an extension.
Searching for `convert` or PIL has non-negligible performance overhead, so it's
preferable to only do it when really necessary. This way, the search is only
performed when ArtResizer.shared is accessed for the first time.
An earlier commit broke the call to art_for_album here (too few arguments).
I've also now propagated the maxwidth setting for the command to match the
import hook.
Fixed a number of issues with the changes to fetchart:
- Remove redundant fetches. This was making the Amazon source download every
image twice even when art resizing was not enabled!
- Restore local_only switch in plugin hook, which got lost in the shuffle at
some point.
- Don't replace the original image file in-place; use a temporary file instead.
This would clobber the original source image on the filesystem with the
downscaled version!
The previous method was to change self.__class__ dynamically to make __init__
instantiate different classes. This new way, which uses bare functions instead
of separate functor-like classes, instead just forwards the resize() call to
a module-global implementation based on self.method.
Additionally, the semantics of ArtResizer have changed. Clients now *always*
call resize() and proxy_url(), regardless of method. The method makes *one* of
these a no-op. This way, clients need not manually inspect which method is
being used.
- Safer proxy resize. The URL parameters are now properly encoded. And a
spurious additional request has been removed.
- Removed manual search of $PATH. Invoking "convert" without a path does this
automatically.
- More pyflakes-friendly test import of PIL.
- Do not delete the NamedTemporaryFile -- doing so creates a race condition
where the file might be created between the filename generation and the tool
invocation.
artresizer.py instances an ArtResizer object that uses internally the PIL; ImageMagick
or a web proxy service to perform the resizing operations.
Because embedart works on input images located on filesystem it requires PIL or ImageMagick, whereas
fetchart is able to do the job with the fallback webproxy resizer.
This message was being logged as an error every time MediaFile failed to parse a
file. But this is not actually an error -- the importer uses FileTypeErrors to
determine whether a file is music or not. This resulted in error logs for every
album art file, .m3u, etc. in the imported directory. Verbose output is a better
home for this message.
Paging @yagebu: I think the old version of the code would embed album art into
the wrong file. Please correct me (and accept my apologies) if I'm wrong
though.
A user reported a problem with one of the logging statements where .format()
tried to convert a Unicode string to bytes because the log message was '', not
u''. As a rule, we should ensure that all logging statements use Unicode
literals.
Also pertaining to #58: for most utility functions, paths should *not* be
`syspath`-ified. (This only occurs right before a path is sent to the OS.) In
fact, as @Wessie discovered, using the result of `syspath` with `ancestry` leads
to incorrect behavior. I checked and this should not currently happen anywhere,
but these docstring changes make that requirement explicit.
This is an alternative to #58 that makes bytestring_path perform more like the
inverse of syspath on Windows. This way, we can convert to syspath, operate on
the path, and then bring back to internal representation without data loss. This
involves looking for the magic prefix on the Unicode string and removing it
before encoding to the internal (UTF-8) representation.
With the new centralized print_obj function, we can greatly simplify the code
for the list command. This necessitated a couple of additional tweaks:
- For performance reasons, print_obj can now take a compiled template. (There's
still an issue with using the default/configured template, but we can cross
that bridge later).
- When listing albums, $path now expands to the album's item dir. So the format
string '$path' now exactly corresponds to passing the -p switch.
As an added bonus, we can now also reduce copypasta in the random plugin (which
behaves almost exactly the same as list).
The list_format_album and list_format_item options now *actually* affect the
display in commands other than "beet list". This replaces the -f/--format flags
-- if any users want to control this on the command line, we can reconsider this
decision.
Note that this involved passing around a "config" object, which we previously
haven't done. This seems a little bit messy, but configuration is about to
change entirely to be more like this style -- so this isn't a huge liability.
This version of the (renamed) _print_obj function uses introspection to
determine whether we're printing an Album or an Item. It's like function
overloading for Python! 😁
