See the [documentation](https://docs.softwareheritage.org/devel/swh-storage/index.html) for more details. ## Quick start ### Dependencies Python tests for this module include tests that cannot be run without a local Postgresql database, so you need the Postgresql server executable on your machine (no need to have a running Postgresql server). They also expect a cassandra server. #### Debian-like host ``` $ sudo apt install libpq-dev postgresql-11 cassandra ``` #### Non Debian-like host The tests expects the path to `cassandra` to either be unspecified, it is then looked up at `/usr/sbin/cassandra`, either specified through the environment variable `SWH_CASSANDRA_BIN`. Optionally, you can avoid running the cassandra tests. ``` (swh) :~/swh-storage$ tox -- -m 'not cassandra' ``` ### Installation It is strongly recommended to use a virtualenv. In the following, we consider you work in a virtualenv named `swh`. See the [developer setup guide](https://docs.softwareheritage.org/devel/developer-setup.html#developer-setup) for a more details on how to setup a working environment. You can install the package directly from [pypi](https://pypi.org/p/swh.storage): ``` (swh) :~$ pip install swh.storage [...] ``` Or from sources: ``` (swh) :~$ git clone https://forge.softwareheritage.org/source/swh-storage.git [...] (swh) :~$ cd swh-storage (swh) :~/swh-storage$ pip install . [...] ``` Then you can check it's properly installed: ``` (swh) :~$ swh storage --help Usage: swh storage [OPTIONS] COMMAND [ARGS]... Software Heritage Storage tools. Options: -h, --help Show this message and exit. Commands: rpc-serve Software Heritage Storage RPC server. ``` ## Tests The best way of running Python tests for this module is to use [tox](https://tox.readthedocs.io/). ``` (swh) :~$ pip install tox ``` ### tox From the sources directory, simply use tox: ``` (swh) :~/swh-storage$ tox [...] ========= 315 passed, 6 skipped, 15 warnings in 40.86 seconds ========== _______________________________ summary ________________________________ flake8: commands succeeded py3: commands succeeded congratulations :) ``` Note: it is possible to set the `JAVA_HOME` environment variable to specify the version of the JVM to be used by Cassandra. For example, at the time of writing this, Cassandra does not support java 14, so one may want to use for example java 11: ``` (swh) :~/swh-storage$ export JAVA_HOME=/usr/lib/jvm/java-14-openjdk-amd64/bin/java (swh) :~/swh-storage$ tox [...] ``` ## Development The storage server can be locally started. It requires a configuration file and a running Postgresql database. ### Sample configuration A typical configuration `storage.yml` file is: ``` storage: cls: postgresql db: "dbname=softwareheritage-dev user= password=" objstorage: cls: pathslicing root: /tmp/swh-storage/ slicing: 0:2/2:4/4:6 ``` which means, this uses: - a local storage instance whose db connection is to `softwareheritage-dev` local instance, - the objstorage uses a local objstorage instance whose: - `root` path is /tmp/swh-storage, - slicing scheme is `0:2/2:4/4:6`. This means that the identifier of the content (sha1) which will be stored on disk at first level with the first 2 hex characters, the second level with the next 2 hex characters and the third level with the next 2 hex characters. And finally the complete hash file holding the raw content. For example: 00062f8bd330715c4f819373653d97b3cd34394c will be stored at 00/06/2f/00062f8bd330715c4f819373653d97b3cd34394c Note that the `root` path should exist on disk before starting the server. ### Starting the storage server If the python package has been properly installed (e.g. in a virtual env), you should be able to use the command: ``` (swh) :~/swh-storage$ swh storage rpc-serve storage.yml ``` This runs a local swh-storage api at 5002 port. ``` (swh) :~/swh-storage$ curl http://127.0.0.1:5002 Software Heritage storage server

You have reached the Software Heritage storage server.
See its documentation and API for more information

``` ### And then what? In your upper layer ([loader-git](https://forge.softwareheritage.org/source/swh-loader-git/), [loader-svn](https://forge.softwareheritage.org/source/swh-loader-svn/), etc...), you can define a remote storage with this snippet of yaml configuration. ``` storage: cls: remote url: http://localhost:5002/ ``` You could directly define a postgresql storage with the following snippet: ``` storage: cls: postgresql db: service=swh-dev objstorage: cls: pathslicing root: /home/storage/swh-storage/ slicing: 0:2/2:4/4:6 ``` ## Cassandra As an alternative to PostgreSQL, swh-storage can use Cassandra as a database backend. It can be used like this: ``` storage: cls: cassandra hosts: - localhost objstorage: cls: pathslicing root: /home/storage/swh-storage/ slicing: 0:2/2:4/4:6 ``` The Cassandra swh-storage implementation supports both Cassandra >= 4.0-alpha2 and ScyllaDB >= 4.4 (and possibly earlier versions, but this is untested). While the main code supports both transparently, running tests or configuring the schema requires specific code when using ScyllaDB, enabled by setting the `SWH_USE_SCYLLADB=1` environment variable. diff --git a/sql/upgrades/178.sql b/sql/upgrades/178.sql new file mode 100644 index 00000000..6e3c575d --- /dev/null +++ b/sql/upgrades/178.sql @@ -0,0 +1,9 @@ +-- SWH DB schema upgrade +-- from_version: 177 +-- to_version: 178 +-- description: add bzr to revision_type values + +insert into dbversion(version, release, description) + values(178, now(), 'Work In Progress'); + +alter type revision_type add value 'bzr'; diff --git a/swh.storage.egg-info/PKG-INFO b/swh.storage.egg-info/PKG-INFO index 0e847f7e..854b38bc 100644 --- a/swh.storage.egg-info/PKG-INFO +++ b/swh.storage.egg-info/PKG-INFO @@ -1,250 +1,250 @@ Metadata-Version: 2.1 Name: swh.storage -Version: 0.37.0 +Version: 0.37.1 Summary: Software Heritage storage manager Home-page: https://forge.softwareheritage.org/diffusion/DSTO/ Author: Software Heritage developers Author-email: swh-devel@inria.fr License: UNKNOWN Project-URL: Bug Reports, https://forge.softwareheritage.org/maniphest Project-URL: Funding, https://www.softwareheritage.org/donate Project-URL: Source, https://forge.softwareheritage.org/source/swh-storage Project-URL: Documentation, https://docs.softwareheritage.org/devel/swh-storage/ Platform: UNKNOWN Classifier: Programming Language :: Python :: 3 Classifier: Intended Audience :: Developers Classifier: License :: OSI Approved :: GNU General Public License v3 (GPLv3) Classifier: Operating System :: OS Independent Classifier: Development Status :: 5 - Production/Stable Requires-Python: >=3.7 Description-Content-Type: text/markdown Provides-Extra: testing Provides-Extra: journal License-File: LICENSE License-File: AUTHORS swh-storage =========== Abstraction layer over the archive, allowing to access all stored source code artifacts as well as their metadata.
