 # SWH Tarball Loader
 
-The Software Heritage Tarball Loader is a tool and a library to
-uncompress a local tarball and inject into the SWH dataset its tree
-representation.
+The Software Heritage Tarball Loader is in charge of ingesting the
+directory representation of the tarball into the Software Heritage
+archive.
 
 ## Configuration
 
 This is the loader's (or task's) configuration file.
 
 *`{/etc/softwareheritage | ~/.config/swh | ~/.swh}`/loader/tar.yml*:
 
 ```YAML
-extraction_dir: /home/storage/tmp/
+working_dir: /home/storage/tmp/
 storage:
   cls: remote
   args:
     url: http://localhost:5002/
 ```
 
 ## API
 
-Load tarball directly from code or python3's toplevel:
+### local

+Load local tarball directly from code or python3's toplevel:
 
 ``` Python
 # Fill in those
-repo = 'loader-tar.tgz'
+repo = '8sync.tar.gz'
 tarpath = '/home/storage/tar/%s' % repo
-origin = {'url': 'ftp://%s' % repo, 'type': 'tar'}
+origin = {'url': 'file://%s' % repo, 'type': 'tar'}
 visit_date = 'Tue, 3 May 2017 17:16:32 +0200'

-    'committer': {'name': 'some', 'fullname': 'one', 'email': 'something'},
-    'message': '1.0 Released',
-    'date': None,
-    'committer_date': None,
-    'type': 'tar',

 import logging
 logging.basicConfig(level=logging.DEBUG)
 
 from swh.loader.tar.tasks import LoadTarRepository
 l = LoadTarRepository()
-l.run_task(tar_path=tarpath, origin=origin, visit_date=visit_date,
-           revision=revision, branch_name='master')
-```
-
-## Celery
-
-Load tarball using celery.
-
-Providing you have a properly configured celery up and running, the
-celery worker configuration file needs to be updated:
-
-*`{/etc/softwareheritage | ~/.config/swh | ~/.swh}`/worker.yml*:
-
-``` YAML
-task_modules:
-  - swh.loader.tar.tasks
-task_queues:
-  - swh_loader_tar
-```
-
-cf. https://forge.softwareheritage.org/diffusion/DCORE/browse/master/README.md
-for more details
-
-
-## Tar Producer
-
-Its job is to compulse from a file or a folder a list of existing
-tarballs. From this list, compute the corresponding messages to send
-to the broker.
-
-### Configuration
-
-Message producer's configuration file (`tar.yml`):
-
-``` YAML
-# Mirror's root directory holding tarballs to load into swh
-mirror_root_directory: /srv/storage/space/mirrors/gnu.org/gnu/
-# Url scheme prefix used to create the origin url
-url_scheme: http://ftp.gnu.org/gnu/
-type: ftp
-
-# File containing a subset list tarballs from mirror_root_directory to load.
-# The file's format is one absolute path name to a tarball per line.
-# NOTE:
-# - This file must contain data consistent with the mirror_root_directory
-# - if this option is not provided, the mirror_root_directory is scanned
-# completely as usual
-# mirror_subset_archives: /home/storage/missing-archives
-
-# Randomize blocks of messages and send for consumption
-block_messages: 250
-```
-
-### Run
-
-Trigger the message computations:
-
-```Shell
-python3 -m swh.loader.tar.producer --config ~/.swh/producer/tar.yml
+l.run_task(origin=origin, visit_date=visit_date,
+	       last_modified=last_modified)
 ```
 
-This will walk the `mirror_root_directory` folder and send encountered
-tarball messages for the swh-loader-tar to uncompress (through
-celery).
-
-If the `mirror_subset_archives` is provided, the tarball messages will
-be computed from such file (the `mirror_root_directory` is still used
-so please be consistent).
-
-If problem arises during tarball message computation, a message will
-be output with the tarball that present a problem.
-
-It will displayed the number of tarball messages sent at the end.
+### remote
 
-### Dry run
+Load remote tarball is the same sample
 
-``` Shell
-python3 -m swh.loader.tar.producer --config-file ~/.swh/producer/tar.yml --dry-run
-```
-
-This will do the same as previously described but only display the
-number of potential tarball messages computed.
