This allows us to run checks and fix types only on those that were
really modified. On our fdroiddata repo, with 2k apps with many unset
fields and flags, this reduces readmeta runtime from ~1.3s to ~1.1s.
Avoids typos, such as one I just found which was 'strsng' isntead of
'string'. The static analyzer can catch those if they are constants.
Comparing ints is also faster than strings, which adds up in readmeta.
Only keep lists in metadata files in the json format, since they don't
support multiline strings that are readable.
This makes the internal code easier, and a bit faster.
This simplifies usage, goes from
build['flag']
to
build.flag
Also makes static analyzers able to detect invalid attributes as the set
is now limited in the class definition.
As a bonus, setting of the default field values is now done in the
constructor, not separately and manually.
While at it, unify "build", "thisbuild", "info", "thisinfo", etc into
just "build".
This simplifies usage, goes from
app['Foo']
to
app.Foo

Don't log and exit in an inner metadata function. Handle it at a higher
level and do a proper exception. This also avoids unnecessary passing of
apps all around.
For a bit repo like f-droid.org, it makes sense to standardize on a single
format for metadata files. This adds support for enforcing a single data
format, or a reduced set of data formats. So f-droid.org would run like
this if it changed to YAML:
accepted_formats = ['txt', 'yaml']
Then once everything was converted to YAML, it could look like this:
accepted_formats = ['yaml']
In order to prevent confusion caused by multiple metadata files for a given
app, fdroid will exit with an error if it finds any app metadata file with
the same package ID as one that has already been parsed.
This puts process of setting up the defaults for the internal dict
that represents a parsed app into a single method that is reused for all
metadata formats.
YAML is a format that is quite similar to the .txt format, but is a
widespread standard that has editing modes in popular editors. It is also
easily parsable in python.
The .pickle for testing is a lightly edited version of the real metadata
for org.videolan.vlc:
