Summary

This is an early implementation of the swh-fuse system. What is working right
now:

  • mounting dir/cnt
  • ls/cd/cat
  • disk cache for metadata/blob

What needs to be done before merging:

  • Add documentation
  • Add type hints everywhere
  • Add unit/functional tests

There are still a lot of TODO in the code, but feel free to comment!

commit f6db4a64d8d1885c769d4461cc932aabf8998ab6

    fuse: remove internal entry2inode dictionnary

commit 6899845367e8865b5b5dcec7f3d13893d9be2f4e
Author: Thibault Allançon <haltode@gmail.com>
Date:   Fri Oct 2 15:39:15 2020 +0200

    fs: rework code architecture
    
    Better class abstraction. Now the information is less scattered around
    the code (especially for fuse.py). Each FUSE entry virtual type is
    self-contained and defines entirely how it is used, listed, read, etc.

    tests: add unit tests framework
    
    - Create a pytest fixture to run swh-fuse in a separate process and
      setup an offline mock web API
    - Add basic cnt/dir tests

    cli: use a config.yml file to configure cache/web-api
    
    More flexible and easier to tweak settings. For example we can now have,
    the metadata cache in-memory while the blob cache is on-disk:
    
      cache:
        metadata:
          in-memory: true
        blob:
          path: /cache/dir/blob.sqlite

commit 2955a34287645b0c9c1db2ca15880628e89fd778
Author: Thibault Allançon <haltode@gmail.com>
Date:   Thu Oct 1 11:13:26 2020 +0200

    cache: separate metadata and blob caches
    
    Rework the cache architecture. The cache code is now separated into
    multiple classes (one for each cache type, and one global). Every cache
    is now used as a context manager and must implement `__getitem__` and
    `__setitem__` to access/update the underlying cache information.

    fuse: remove internal entry2inode dictionnary

Author: Thibault Allançon <haltode@gmail.com>
Date:   Fri Oct 2 15:39:15 2020 +0200

    fs: rework code architecture
    
    Better class abstraction. Now the information is less scattered around
    the code (especially for fuse.py). Each FUSE entry virtual type is
    self-contained and defines entirely how it is used, listed, read, etc.

    cli: use a config.yml file to configure cache/web-api
    
    More flexible and easier to tweak settings. For example we can now have,
    the metadata cache in-memory while the blob cache is on-disk:
    
      cache:
        metadata:
          in-memory: true
        blob:
          path: /cache/dir/blob.sqlite

Date:   Thu Oct 1 11:13:26 2020 +0200

    cache: separate metadata and blob caches
    
    Rework the cache architecture. The cache code is now separated into
    multiple classes (one for each cache type, and one global). Every cache
    is now used as a context manager and must implement `__getitem__` and
    `__setitem__` to access/update the underlying cache information.

    - Handle `cnt` and `dir` artifacts
    - User-level commands working: ls, cd, cat
    - Metadata and blob are cached using SQLite

    tests: add unit tests framework
    
    - Create a pytest fixture to run swh-fuse in a separate process and
      setup an offline mock web API
    - Add basic cnt/dir tests

    cli: use a config.yml file to configure cache/web-api
    
    More flexible and easier to tweak settings. For example we can now have,
    the metadata cache in-memory while the blob cache is on-disk:
    
      cache:
        metadata:
          in-memory: true
        blob:
          path: /cache/dir/blob.sqlite

    cache: separate metadata and blob caches
    
    Rework the cache architecture. The cache code is now separated into
    multiple classes (one for each cache type, and one global). Every cache
    is now used as a context manager and must implement `__getitem__` and
    `__setitem__` to access/update the underlying cache information.

    the Software Heritage archive.

    self-contained and defines entirely how it is used, listed, read, etc.

    cache: separate metadata and blob caches
    
    Rework the cache architecture. The cache code is now separated into
    multiple classes (one for each cache type, and one global). Every cache
    is now used as a context manager and must implement `__getitem__` and
    `__setitem__` to access/update the underlying cache information.

seirl requested changes to this revision.EditedOct 6 2020, 6:34 PM

This is looking pretty great. I see three more good refactoring possibilities:

  • drop inode2path, this mapping doesn't seem to serve a purpose anymore
  • the way files are split in fs/ is weird to me, like ArtifactEntry not being in artifact. I don't see an obvious way of splitting them, maybe they just all belong in the same file?
  • I agree that the fuse class <-> entries cycle isn't so elegant. I think we actually don't have to do that. We could create another object, say FuseBackend, that contains the cache, get_blob, get_metadata(), get_cached_swhids(), alloc_inode() and inode2entry(). We can then pass this backend around between the Fuse class and all the entries.

Does that sound better?

swh/fuse/fuse.py

114

This method should go in the FuseEntry base class.

Unlike what you had before, this won't get called if there is an exception before. Maybe use a finally block?

    fs: rework code architecture
    
    Better class abstraction. Now the information is less scattered around
    the code (especially for fuse.py). Each FUSE entry virtual type is
    self-contained and defines entirely how it is used, listed, read, etc.

    fuse: remove unnecessary inode2path

commit c1bfbcece32aada7b4992f3804a10e66b690effa
Author: Thibault Allançon <haltode@gmail.com>

    fuse: remove unnecessary fd maps (use inode instead)

commit 34c5d37c0d77da24a9dee4ad06986b058618a469
Author: Thibault Allançon <haltode@gmail.com>
Date:   Tue Oct 6 12:09:27 2020 +0200

    fuse: get_blob: use bytes instead of string
    
    We do not know the encoding beforehand so manipulate every blob coming
    from the archive as bytes.

commit f16985f52dab591b7eb6cd567ef772e3d77010df
Author: Thibault Allançon <haltode@gmail.com>
Date:   Tue Oct 6 10:42:50 2020 +0200

    fuse: add async to the codebase
    
    - Change class interface to match async interface (eg: iter -> aiter)
    - Sync code is now running with `run_in_executor`
    - Use aiosqlite as the async interface for sqlite

    fuse: lookup: raise and log exception when name not found

Author: Thibault Allançon <haltode@gmail.com>
Date:   Mon Oct 5 11:57:07 2020 +0200

    fuse: read: use `offset` and `length` parameters
    
    This is necessary to read very long files, or use a terminal pager.

Author: Thibault Allançon <haltode@gmail.com>

    cli: use SWHIDParamType from swh.model.cli
    
    See D4139.

commit f7194e5a192c534c1ce8dcac1a048627ee17107a
Author: Thibault Allançon <haltode@gmail.com>
Date:   Mon Oct 5 10:05:15 2020 +0200

    fuse: remove internal entry2inode dictionnary

commit fc0dd584018c3fbc2b08405d962c7773766427d1
Author: Thibault Allançon <haltode@gmail.com>
Date:   Fri Oct 2 15:39:15 2020 +0200

    fs: rework code architecture
    
    Better class abstraction. Now the information is less scattered around
    the code (especially for fuse.py). Each FUSE entry virtual type is
    self-contained and defines entirely how it is used, listed, read, etc.

commit 9d60949c1295ef666f4c1e07042e16053614ec9d
Author: Thibault Allançon <haltode@gmail.com>

    tox.ini: pin black version to 19.10b0

commit 9417ab147eab9520d40b624be7aa6990176614ed
Author: Thibault Allançon <haltode@gmail.com>
Date:   Wed Sep 30 16:46:12 2020 +0200

    tests: add unit tests framework
    
    - Create a pytest fixture to run swh-fuse in a separate process and
      setup an offline mock web API
    - Add basic cnt/dir tests

commit 8c77b5cdc2eb20b500ffa908d03385c1ff6a746b
Author: Thibault Allançon <haltode@gmail.com>
Date:   Thu Oct 1 15:27:48 2020 +0200

    cli: use a config.yml file to configure cache/web-api
    
    More flexible and easier to tweak settings. For example we can now have,
    the metadata cache in-memory while the blob cache is on-disk:
    
      cache:
        metadata:
          in-memory: true
        blob:
          path: /cache/dir/blob.sqlite

commit 4a67601e741eed815f868ae30d46b049dc0b292a
Author: Thibault Allançon <haltode@gmail.com>
Date:   Thu Oct 1 11:13:26 2020 +0200

    cache: separate metadata and blob caches
    
    Rework the cache architecture. The cache code is now separated into
    multiple classes (one for each cache type, and one global). Every cache
    is now used as a context manager and must implement `__getitem__` and
    `__setitem__` to access/update the underlying cache information.
