So that the SQL backend is more useable, let the MediaEntry
have a faked media_data.
It's extremely fake: The returned dict is always a new one.
So any stored info is even lost!
Change the media_data for video from
entry.media_data["video"] to use entry.media_data directly.
Also start a bare MediaEntry.media_data_init(**kwargs)
method for setting up the media_data and possibly
initialising it with kwargs.
* Added extlib/freesound/audioprocessing.py
* config_spec
* Added create_spectrogram setting
* Added media:medium and media:thumb max_{width,height} settings
* Added sniffing logic to
- audio.processing:sniff_handler
- video.processing:sniff_handler
* Changed audio.processing:sniff_handler logic
* Added audio thumbnailing functionality to audio.processing
(works only with create_spectrogram enabled)
* Refractored contexts in audio.processing
* Added audio.transcoders:AudioThumbnailer
Used for creating spectrograms and spectrogram thumbnails -
Wadsworth's Constant, we meet again :)
* audio.transcoders:AudioTranscoder
- Added mux_string kwarg
- Delete self.pipeline on self.halt()
* Changed str.format formatting in image.processing:sniff_handler
Had {1} without an {0}, changed to {0}
* Refractored VideoTranscoder to use transcode() for transcoding instead
of __init__()
* Added discover() method to video.transcoders:VideoTranscoder
* Added spectrogram display to media_displays/audio.html
* Updated test_submission to reflect changes in media plugin delegation
It's good practice to cleanup the SQL session after each
request so that the next request gets a fresh one.
It's an application decision whether one wants a
just-in-case ROLLBACK or COMMIT. There are two ideas behind
it, really. I have decided for ROLLBACK. The idea is "if
you forget to commit your changes yourself, there's
something broken. Maybe you got an exception?".
attachments working with the sql backend.
- SQL Schema for attachment files, ordering attachments by
their name, not by the submission order (as earlier).
- Dot-Notation for attachments, where missing.
- convert existing attachments over from mongo -> sql
I don't know exactly why, but an exception during
processing hasn't found its way up. The entry was marked as
failed and that was it. So I decided to add a _log.warn to
the part of mark_entry_failed that handles general
exceptions.
* cwebber/celerysql:
Adjust unit tests to match new celery/kombu sqlalchemy setup
"database" is not the sqlalchemy kombu transport... should be "sqlalchemy"
Celery and kombu databases should also be .gitignore'd
kombu-sqlalchemy a requirement in order for kombu sqlalchemy transport to work
Move mediagoblin dbs out of user_dev for race condition directory-creation reasons.
Give kombu its own db. Responding to Elrond "sqlite will lock all the time!" :)
Apparently an absolute path is three slashes after sqlite:. Thx elrond.
Should be all that's needed to switch celery/kombu settings to sqlalchemy
Some parts in the code like to use .setdefault(). So make
them happy and provide a minimal version. It ignores the
given default and expects the attribute to already exist.
Other parts use .delete() to delete a complete object. This
version expects the object to live in a session and also
does the final commit.
There was no place in the software telling the user the
version in use. So start by having the main server emit a
startup notice including the version string. Uses python
logging, so should be easy to reconfigure, etc.
To allow easier migration to the SQLAlchemy style .id give
the User and MediaEntry mongo classes an alias attribute of
.id that maps to ['_id'].
Use it in the upload process, because this was one of the
last positions with a ['_id'] instead of ._id (due to a bug
in mongokit).
Finally, to make testing of sql a bit easier, create a
bin/gmg command to do the conversion from mongo to sql.
It's currently named "convert_mongo_to_sql".
The most important option is the gmg -cf option to give a
configfile with the appropiate sql_engine definition.
Order the conversion by the "created" attribute. That way
the sql ids are mostly in the order they would have been,
if sql was used earlier.
Makes things nicer to look at in a db dump.
The task_id is created anyway as a UUID. So it is very
unique per definition. The only thing needed for the queue
file path is a unique part.
Before the objectid of the MediaEntry was used instead. But
in the sql world the objectid is only available after an
"insert" on the db. And creating the queue_file_path
afterwards would require an "update" on the db. We can save
that. ... for now.
Mostly this means: Havintg a config_spec.ini that has a
local (relative to mediagoblin.ini) sqlite db with the name
"mediagoblin.db".
Also:
- Add to .gitignore
- Add a notice to mediagoblin.ini about the db
fail_metadata used to be a dict in mongo. So a json encoded
field should be okay too.
We could use a pickled field instead, which would be more
flexible.
After a bit of discussion, we decided to drop the
pre-rendered html from the database and render it on
the fly.
In another step, we will use some proper caching method to
cache this stuff.
