# Builtin Actor Bundles
|
|
|
|
With NV16, builtin actor bundles must be loaded into lotus for the FVM to operate.
|
|
|
|
The bundles are specified in build/bundles.toml using the following syntax:
|
|
```toml
|
|
[[bundles]]
|
|
version = X # actors version
|
|
release = tag # release gag
|
|
```
|
|
|
|
This will add a bundle for version `X`, using the github release `tag`
|
|
to fetch the bundles at first startup.
|
|
|
|
If you don't want to fetch the bundle from github, you can specify an explicit path to the bundle (which must be appropriate for your network, typically mainnet):
|
|
```toml
|
|
[[bundles]]
|
|
version = X # actors version
|
|
release = tag # release tag
|
|
path = /path/to/builtin-actors.car
|
|
```
|
|
|
|
For development bundles, you can also specify `development = true` so that the bundle is not
|
|
recorded in the datastore and reloaded every time the daemon starts up:
|
|
```toml
|
|
[[bundles]]
|
|
version = X # actors version
|
|
release = tag # release gag
|
|
path = /path/to/builtin-actors.car
|
|
development = true
|
|
```
|
|
|
|
## Local Storage
|
|
|
|
Bundles downloaded from github will be stored in
|
|
`$LOTUS_PATH/builtin-actors/vXXX/YYY/builtin-actors-ZZZ.car``, where
|
|
`XXX` is the actors version, `YYY` is the release tag, and `ZZZ` is
|
|
the network bundle name.
|
|
|
|
The sha256 sum of the bundle will be stored next to it, in
|
|
`$LOTUS_PATH/builtin-actors/vXXX/YYY/builtin-actors-ZZZ.sha256`
|
|
|
|
On startup, if a bundle is recorded as loaded the manifest CID will be
|
|
checked for presence in the blockstore. If the manifest is missing,
|
|
then the bundle will be reloaded from the local file (if it exists) or
|
|
refetched from github. The sha256 sum is always checked before
|
|
loading the bundle.
