### Replacing a built-in module
|
||||
|
||||
A custom module which extends a built-in one runs alongside it, and when the
|
||||
two share a slug they write to the same results file. MVT warns about that
|
||||
collision, naming both modules, where each came from and the file the later one
|
||||
overwrites, but it runs them both. Set `replaces` to the class the module
|
||||
supersedes to take that module's place instead: when both are available to a
|
||||
command, the named module is dropped from the run.
|
||||
|
||||
```python
|
||||
from mvt.ios.modules.backup import Manifest as BuiltinManifest
|
||||
|
||||
|
||||
class Manifest(BuiltinManifest):
|
||||
supported_commands = (("ios", "check-backup"),)
|
||||
replaces = BuiltinManifest
|
||||
```
|
||||
|
||||
Keeping the class name of the replaced module, as above, keeps the name
|
||||
`--module` selects the module by and the slug its results file is named after.
|
||||
A replacement with a different class name writes to a file named after its own
|
||||
slug, unless it sets `slug` to the slug of the module it replaces, and
|
||||
`--module` still selects it by the name of the replaced module, which MVT logs.
|
||||
Taking over the slug of a replaced module is not a collision and is not warned
|
||||
about, because that module is no longer part of the run.
|
||||
|
||||
Modules which depend on the replaced module receive the replacement instead, so
|
||||
`get_dependency_results(BuiltinManifest)` returns the replacement's results. A
|
||||
module must not depend on the module it replaces: that module does not run, so
|
||||
the replacement has to produce the data itself, and MVT logs a warning when a
|
||||
module declares both.
|
||||
|
||||
A replacement takes on the obligations of the module it replaces. If it
|
||||
declares a dependency the command does not provide, it is skipped like any
|
||||
other module with an unavailable dependency, and the module it replaced stays
|
||||
out of the run: neither of them produces results, and the modules depending on
|
||||
the replaced module are skipped as well.
|
||||
|
||||
Subclassing the replaced module is not required, but a replacement which is not
|
||||
a subclass is logged with a warning, because its results may not be what the
|
||||
modules depending on the replaced module expect. Naming a module the command
|
||||
does not run has no effect, and modules which replace each other in a cycle all
|
||||
keep running and replace nothing. Every applied substitution is logged, so it
|
||||
is recorded in `command.log` when the command runs with an `--output` folder.
|
||||
|
||||
Every command resolves replacements on its own. `check-iocs` matches stored
|
||||
results files against the slugs of the modules available for that command. A
|
||||
replacement which subclasses the module it replaces inherits its
|
||||
`check_indicators()`. It is then part of `check-iocs` for its platform and
|
||||
re-checks the results file named after its slug. A replacement with no
|
||||
`check_indicators()` is not part of `check-iocs`. The built-in module it
|
||||
replaced re-checks the file. `check-iocs` matches `--module` on the class name
|
||||
only. Pass a differently named replacement's own name there, not the name of
|
||||
the module it replaces.
