Folds aiida-shell (e420c1d, v0.9.0) into core, so running an arbitrary binary with provenance needs no plugin and no extra package. Closes #7546, step 9 of #7479.

Entry-point names carry over verbatim and node type strings derive from them, so existing nodes and archives keep loading. ShellCode is the exception. launch_shell_job now lives in aiida.engine, PickledData and EntryPointData in aiida.orm, and dill is a new runtime dependency, imported lazily.

LICENSE.txt open_source_licenses.txt

The first commit is the move and is best read against that map; the others are one change each:

  • ShellCode removed for InstalledCode, which it only specialised by validating its default plugin. Migrations in all three storage chains rewrite existing nodes, which would otherwise load silently as bare Data.
  • Two wrong annotations, caught by core's warn_unreachable: prepare_filenames and the nodes port type.
  • PickledData never reported version mismatches, comparing the installed version against itself, at info level on a warning-level logger.
  • Tutorials no longer install aiida-shell: with both present, every shared entry point raises MultipleEntryPointError.

Each migration was falsification-checked by neutering its UPDATE and confirming the test fails. A pre-v3 archive holding a ShellCode was imported end to end: verdi archive import migrates it and the node arrives as a working InstalledCode. The PickledData fix ships a regression test demonstrated failing on the old code and passing on the new.

Follow-ups: archive aiida-shell (no shim, its aiida-core~=2.6 pin already blocks co-installation with v3), aiida-workgraph must drop its dependency on it, and the cheatsheet still lists it. Further v3 migrations should extend main_0003 rather than stack onto it.

Changes

Shell job integration

Layer / File(s) Summary
Parser serialization and data plugins
src/aiida/orm/nodes/data/*, pyproject.toml, tests/orm/data/*
Added EntryPointData and PickledData for persistent parser references and serialized parser callables. Registered both data plugins and added tests.
ShellJob execution and parsing
src/aiida/calculations/shell.py, src/aiida/parsers/plugins/shell.py, tests/calculations/*, tests/parsers/*
Added shell command inputs, file and remote-data handling, validation, output retrieval, parser hooks, exit codes, and comprehensive tests.
Launcher API and user-facing integration
src/aiida/engine/*, docs/source/howto/*, docs/source/tutorials/*, tests/engine/*
Added and exported launch_shell_job, computer and code preparation, node conversion, submission support, documentation, and tutorial updates.
ShellCode storage migration
src/aiida/storage/*/migrations/*, tests/storage/*, tests/tools/archive/*
Added profile and archive migrations that rewrite ShellCode node types to InstalledCode, with migration tests and schema fixtures.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 46ce5

This PR brings shell execution and custom parser support into core, but requested output paths can still escape the retrieved directory and copy daemon-readable files into provenance, while callable parser data is deserialized without a confirmed trust boundary. The current implementation is not merge-ready until these security risks are addressed or explicitly accepted.

Restore the db_dbsetting schema records.

The migration only updates db_dbnode.node_type, so the expected schema must retain them. Add the missing index and table definitions.

Validate parser parameter order and kind.

validate_parser accepts (parser, dirpath) and (dirpath, *, parser) because it sorts parameter names. ShellParser.call_parser_hook invokes two-parameter hooks as unpickled_parser(dirpath, self). The keyword-only form raises TypeError, which parse maps to ERROR_PARSER_HOOK_EXCEPTED; the reversed form receives the arguments under the wrong names. Validate the ordered inspect.Parameter objects and allow only dirpath first, followed by an optional positional parser.

Fold the `aiida-shell` package into core. Entry-point names are carried
over verbatim, and node type strings are derived from those names rather
than from module paths, so nodes written by `aiida-shell` keep loading
unchanged.

Source:

  calculations/shell.py  ->  aiida/calculations/shell.py
  parsers/shell.py       ->  aiida/parsers/plugins/shell.py
  data/pickled.py        ->  aiida/orm/nodes/data/pickled.py
  data/entry_point.py    ->  aiida/orm/nodes/data/entry_point.py
  data/code.py           ->  aiida/orm/nodes/data/code/shell.py
  launch.py              ->  aiida/engine/launch.py
  LICENSE.txt            ->  open_source_licenses.txt

Tests, mirroring where the code landed:

  calculations/test_shell.py -> tests/calculations/test_shell.py
  parsers/test_shell.py      -> tests/parsers/test_shell.py
  data/test_pickled.py       -> tests/orm/data/test_pickled.py
  data/test_entry_point.py   -> tests/orm/data/test_entry_point.py
  data/test_code.py          -> tests/orm/data/code/test_shell.py
  test_launch.py             -> tests/engine/test_launch_shell_job.py

The package markers, `py.typed` and `__version__` are dropped, as are
`test_version.py`, the documentation, CI workflows and repository
configuration.

The package's `conftest.py` is dissolved onto core's fixtures. Its
`aiida_profile` override goes: core's own fixture already provides a
broker and honours `--db-backend` and `--broker-backend`, both of which
the override ignored, so the CI job running on ZeroMQ without a
RabbitMQ service would have failed. `generate_computer` and
`generate_code` become `aiida_computer_local`, `aiida_localhost` and
`aiida_code_installed`. What is genuinely specific to these tests stays
as `generate_shell_code` and `generate_shell_calc_job` in
`tests/calculations/conftest.py`, and the parser helpers in
`tests/parsers/conftest.py`. `generate_shell_calc_job` keeps a name of
its own because core's `generate_calc_job` has a different signature
and is used by four other modules in the same directory.

Six edits go beyond a verbatim copy of the source, each forced by the
destination:

- `launch_shell_job` imports `ShellJob` inside the function body.
  `aiida.calculations.shell` imports `aiida.engine`, so importing it at
  module level from `aiida/engine/launch.py` is a cycle.
- The module-level `submit` is aliased as `_submit_process`, because
  `launch_shell_job` takes a boolean `submit` argument shadowing it.
- `ShellJob` and `ShellParser` no longer declare `__all__`, as no other
  core calculation job or parser does; both are reached through their
  entry points.
- The `nodes` argument of `process_arguments_and_nodes` and
  `prepare_filenames` is annotated `Data`, not `SinglefileData`, which
  is what the port declares. The narrower annotation left the
  `FolderData` and `RemoteData` branches unreachable.
- `prepare_filenames` returns `dict[str, str | None]`, which is what it
  always built and what `write_folder_data` already accepted.
- Imports of sibling data modules are absolute, `t.Union` becomes `|`,
  and one unused unpacked variable is prefixed, for rules core enables
  and `aiida-shell` did not.

- Exception messages are assigned to `msg` before being raised, as core
  does and `aiida-shell` did not. Three defensive guards keep the inline
  form: mypy proves them unreachable and tolerates a bare `raise` there,
  but not the assignment in front of it.

`dill` becomes a runtime dependency, exempt from import checking since
it ships no type information, and floored at 0.3.6. `PickledData`
pickles with `recurse=True`, which arrived in 0.3.0, but only 0.3.6
round-trips what it writes; the requirement came over unpinned, so the
minimum-requirements job resolved `dill==0.2`.

Landing the data plugins in core also brings them into sweeps that walk
every registered node type. `test_all_node_fields` keeps a regression
file per type, and `test_data_exporters` needs a way to build a dummy
instance of anything carrying `_prepare_*` methods, which `ShellCode`
inherits from `InstalledCode`.

Two smaller consequences. The ported `launch_shell_job` tests delete the
computer they create in a `finally` and assert on the log record's
level rather than its position, since the computer is labelled
`localhost` and leaking it breaks every later test in the worker that
wants `aiida_localhost`. And `verdi devel` no longer describes the
localhost it creates as made by `aiida.engine.launch_shell_job`, a
string copied out of `aiida-shell` years ago that named nothing until
this commit, and now names a function that did not create it.

`get_unpickler` is meant to flag that a node was pickled with a
different version of the pickler than the one installed, since that is
the first thing worth knowing when unpickling then fails. It could not.

It overwrote the stored version with the installed package's
`__version__` before comparing it against `importlib.metadata.version`,
which reports that same installed package, so the check compared a
version against itself. It also logged at info level, on a logger that
sits at warning, so even a firing check stayed invisible.

Keep the stored version, compare it against the installed one the way it
was recorded, and log it at warning level. A mismatch does not guarantee
that unpickling breaks, so the message stays conditional.

Importing `dill` at module scope means `import aiida.orm` pays for it,
since the package re-exports every data plugin. Worse, it couples
resolving the `core.pickled` entry point to `dill` being importable:
`load_node_class` catches only `MissingEntryPointError`, so a missing
`dill` would surface as a bare `ImportError` when loading any existing
node of that type, rather than as anything a reader could act on.

Move the import into `get_pickler` and a new `get_default_unpickler`,
which replace the `PICKLER` and `UNPICKLER` class attributes. Both
remain the seam a subclass overrides to store objects with a different
pickler; neither was referenced anywhere outside this module.

GeigerJ2 added a commit to GeigerJ2/aiida-core that referenced this pull request Sep 2, 2026
The fixture builds three codes whose labels deliberately collide with
the first one's pk and uuid, so the tests can pin down how ambiguous
identifiers are resolved. That only means anything if no other codes are
present, and the fixture took whatever the session profile happened to
hold.

It also inherited a computer, imported from an archive by an earlier
test in the same worker, that is labelled `localhost` but carries the
pre-2.0 transport name `local`. `aiida_localhost` cannot match it, so it
tries to insert its own and hits the unique constraint on the label, and
the recovery re-query in the fixture filters on the transport too, so it
misses as well. Every test here then errors during setup.

Requesting `aiida_profile_clean` fixes both: the ambiguity tests get the
isolation they always assumed, and the stale computer is gone before
they run.

The archive is the deeper problem, and it is not addressed here. Its
computer should have been rewritten when entry points gained the `core.`
prefix, but the archive migration maps schedulers only, unlike its
counterpart for the profile backends. Whether the two files ever share a
worker is down to how the tests are distributed, which is why this has
been latent rather than absent.

Port `aiida-shell`'s how-to guide to `docs/source/howto/`, repointing
its imports at `aiida.engine` and its cross-references into core's API.
Its three worked examples are left behind: they need Quantum ESPRESSO,
GROMACS and LAMMPS binaries that the documentation build cannot assume.

Core did not enable `autosectionlabel`, so the guide's one internal
cross-reference gets an explicit target.

Also update what the rest of the documentation says about the package.
It is no longer a plugin, so it goes from the grid of plugins that
extend core, and the guide on running external codes now points at the
new page rather than at a blog post. The tutorial modules told readers
to install it alongside core, which is now actively harmful: both
distributions register the same entry point names with different values,
so every shared name raises `MultipleEntryPointError` until
`aiida-shell` is uninstalled. The changelog says so too, and the
`tutorials` extra no longer requires it either.

That extra still pulls it in through `aiida-workgraph`, which depends on
it. Nothing here can fix that; it needs `aiida-shell` reduced to a shim
that registers no entry points, or `aiida-workgraph` to drop the
dependency. The documentation build is unaffected either way, since no
page resolves those entry points, and the tutorial modules are already
excluded from execution while that integration is pending. Their
`aiida-core` floor is left alone for the same reason: it belongs with
the rest of that clean-up, before the v3 release.

The cheatsheet still lists it. That graphic is checked in as SVG, PNG
and PDF, so relabelling it means regenerating all three.

Assign exception messages before raising.

The repository coding guidelines require formatted exception messages to be assigned to a variable before the exception is raised. Apply this consistently at the ShellJob validation path and the corresponding ShellCode, parser, test-fixture, and PickledData raise sites.

GeigerJ2 added a commit to GeigerJ2/aiida-core that referenced this pull request Sep 2, 2026
Fold the `aiida-shell` package into core. Entry-point names are carried
over verbatim and node type strings derive from those names rather than
from module paths, so nodes written by `aiida-shell` keep loading.

Relative to `src/aiida_shell/` and `src/aiida/`:

  calculations/shell.py  ->  calculations/shell.py parsers/shell.py
  ->  parsers/plugins/shell.py data/pickled.py        ->
  orm/nodes/data/pickled.py data/entry_point.py    ->
  orm/nodes/data/entry_point.py data/code.py           ->
  orm/nodes/data/code/shell.py launch.py              ->
  engine/launch.py

The MIT notice from `LICENSE.txt` is retained in
`open_source_licenses.txt`.

Tests mirror where the code landed. Package markers, `py.typed`,
`__version__`, `test_version.py`, the documentation, CI workflows and
repository configuration are dropped, and `conftest.py` is dissolved
onto core's fixtures: its `aiida_profile` override ignored
`--db-backend` and `--broker-backend`, which core's own fixture honours.
`generate_shell_calc_job` keeps a name of its own because core's
`generate_calc_job` has a different signature and four other modules in
that directory use it.

These edits go beyond a verbatim copy, each forced by the destination:

- `launch_shell_job` imports `ShellJob` in the function body, since
  `aiida.calculations.shell` imports `aiida.engine`.
- `launch_shell_job`'s boolean `submit` argument shadows the module's
  own `submit` function, so that function is aliased `_submit_process`.
- `ShellJob` and `ShellParser` drop `__all__`, as no other core
  calculation job or parser declares one.
- The `nodes` argument is annotated `Data`, which is what the port
  declares; `SinglefileData` left the `FolderData` and `RemoteData`
  branches unreachable.
- `prepare_filenames` returns `dict[str, str | None]`, which is what it
  always built and what `write_folder_data` already accepted.
- Exception messages are assigned before raising. Three defensive guards
  keep the inline `raise`, which mypy tolerates where it rejects the
  assignment in front of it.

`dill` is floored at 0.3.6, the first version that round-trips what
`recurse=True` writes; unpinned, the minimum-requirements job resolved
0.2.

Registering the data plugins brings them into `test_all_node_fields` and
`test_data_exporters`, which need a regression file and a dummy-instance
generator per node type. `verdi devel` no longer credits the localhost
it creates to `launch_shell_job`, a description copied out of
`aiida-shell` that until now named nothing.

`aiida.engine.launch_shell_job`, a description carried over from
`aiida-shell`. That named nothing in core until now; with
`launch_shell_job` integrated it names a real function that does not
create this computer. Credit `verdi devel launch-add` instead.

`get_unpickler` overwrote the stored version with the installed
package's `__version__` before comparing it against
`importlib.metadata.version`, which reports that same package, so the
check compared a version against itself. It also logged at info level on
a logger that sits at warning.

Compare the stored version against the installed one and log at warning.

At module scope, `import aiida.orm` pays for `dill`, and resolving the
`core.pickled` entry point requires it: `load_node_class` catches only
`MissingEntryPointError`, so a missing `dill` would surface as a bare
`ImportError` when loading any existing node of that type.

The `PICKLER` and `UNPICKLER` class attributes become the classmethods
`_get_default_pickler` and `_get_default_unpickler`, which remain the
seam a subclass overrides. Both are private, having no use outside the
class, and both carry `default` to keep them distinct from
`get_unpickler`, which returns what a given node recorded rather than
what the class would choose.

The fixture builds three codes whose labels collide with the first one's
pk and uuid, which only tests ambiguity resolution if no other codes are
present. It took whatever the session profile held.

That includes a computer imported from an archive by an earlier test in
the same worker, labelled `localhost` but carrying the pre-2.0 transport
name `local`, which `aiida_localhost` cannot match and cannot recover
from once the unique label collides. Every test here then errors during
setup.

Port `aiida-shell`'s how-to guide to `docs/source/howto/`, repointing
its imports and cross-references. Its three worked examples stay behind:
they need Quantum ESPRESSO, GROMACS and LAMMPS binaries the
documentation build cannot assume. Core does not enable
`autosectionlabel`, so the one internal cross-reference gets an explicit
target.

The rest of the documentation stops treating `aiida-shell` as a plugin,
and the tutorials no longer install it alongside core: both distribute
the same entry point names, so every shared name raises
`MultipleEntryPointError` until it is uninstalled.

Otherwise, the submit function is shadowed inside the launch_shell_job body. The other alternative would be to rename the submit argument here, but that is an API break from aiida-shell before, so I'd do it as a follow-up.

Considering relocation of the function, so the shadowing does not apply at all. I doubt it should sit under engine...

Ah, I just realized the commit message here was misleading, as it read "a description carried over from
aiida-shell", which sounds like this got moved in now. The previous wording was actually pre-existing in aiida-core, referencing a function that did not exist there but only in aiida-shell. It now becomes somewhat load-bearing, as with the integration of aiida-shell, the function now does exist in aiida-core, but it's still wrong, as it's only ever called from verdi launch-add and verdi launch-multiply-add.

I folded it in as a one-line description change of something that was previously wrong, but I'd also be fine to put it into its own commit, as it goes beyond just the relocations and fixes that are strictly necessary for those.

This actually caused tests to fail for me locally, not sure if it was also in CI, and not sure if it was caused by the diff of this PR. Will have to check again.

`prepare_localhost` credits the computer it creates to
`aiida.engine.launch_shell_job`. That description was copied from
`aiida-shell` back when `verdi devel launch-add` was added, and has
named nothing in core ever since. Integrating `launch_shell_job` turns
it into a reference to a real function, which still is not what creates
this computer, so credit `verdi devel launch-add` instead.

The pickler was selected by overriding a classmethod, while the node
recorded which one it used. Storage was per node, the API per class, and
the subclass existed only to change which function got called.

Take it as a constructor argument instead:

    PickledData(obj)
    PickledData(obj, pickler='cloudpickle')

Any module providing `dumps` and `loads` can be named, checked at
construction rather than at load time. `cloudpickle` then needs no
subclass and no plugin, and every pickled node keeps one node type, so
queries stay uniform. `dill` is imported when a node is written or read
rather than when `aiida.orm` is, which also keeps `load_node_class` from
raising a bare `ImportError` for want of it.

Recording the module name rather than the unpickling function's module
drops `unpickler_name` and stores `dill` in place of `dill._dill`, so a
node no longer depends on `dill`'s private layout to load itself. The
Python version and pickle protocol join what is recorded, being the two
most common reasons an unpickle fails; all three are reported on
mismatch. Nodes written by `aiida-shell` are read through their old
keys.

`load` stays as it is. It is the interface `EntryPointData` shares, so
that the `parser` port can accept either without knowing which it got.

…#7600)

`ShellJob` writes every `SinglefileData` input into the working
directory, so passing a `PickledData` through the `nodes` port dropped
raw pickle bytes there as an input file. Pickled bytes are not a file
the caller supplied, and inheritance said they were.

Store them in the node repository directly, under `obj.pickle`. The
entry point still names the node type, so existing nodes keep loading;
only the inherited `filename` attribute goes.
