ExtrinsicFilter¶

Calls¶

block_extrinsics¶

block the given extrinsics (pallet_name_bytes, function_name_bytes) can uniquely identify an extrinsic if function_name_bytes is None, all extrinsics in pallet_name_bytes will be blocked

Attributes¶

Name	Type
pallet_name_bytes	`Vec<u8>`
function_name_bytes	`Option<Vec<u8>>`

Python¶

call = substrate.compose_call(
    'ExtrinsicFilter', 'block_extrinsics', {
    'function_name_bytes': (
        None,
        'Bytes',
    ),
    'pallet_name_bytes': 'Bytes',
}
)

set_mode¶

Set the mode

The storage of BlockedExtrinsics is unaffected. The reason is we'd rather have this pallet behave conservatively: having extra blocked extrinsics is better than having unexpected whitelisted extrinsics. See the test set_mode_should_not_clear_blocked_extrinsics()

Weights should be 2 DB writes: 1 for mode and 1 for event

Attributes¶

Name	Type
mode	`OperationalMode`

Python¶

call = substrate.compose_call(
    'ExtrinsicFilter', 'set_mode', {'mode': ('Normal', 'Safe', 'Test')}
)

unblock_extrinsics¶

unblock the given extrinsics (pallet_name_bytes, function_name_bytes) can uniquely identify an extrinsic if function_name_bytes is None, all extrinsics in pallet_name_bytes will be unblocked

Attributes¶

Name	Type
pallet_name_bytes	`Vec<u8>`
function_name_bytes	`Option<Vec<u8>>`

Python¶

call = substrate.compose_call(
    'ExtrinsicFilter', 'unblock_extrinsics', {
    'function_name_bytes': (
        None,
        'Bytes',
    ),
    'pallet_name_bytes': 'Bytes',
}
)

Events¶

ExtrinsicsBlocked¶

some extrinsics are blocked

Attributes¶

Name	Type	Composition
pallet_name_bytes	`Vec<u8>`	`Bytes`
function_name_bytes	`Option<Vec<u8>>`	`(None, 'Bytes')`

ExtrinsicsUnblocked¶

some extrinsics are unblocked

Attributes¶

Name	Type	Composition
pallet_name_bytes	`Vec<u8>`	`Bytes`
function_name_bytes	`Option<Vec<u8>>`	`(None, 'Bytes')`

ModeSet¶

a new mode was just sent

Attributes¶

Name	Type	Composition
new_mode	`OperationalMode`	`('Normal', 'Safe', 'Test')`

Storage functions¶

BlockedExtrinsics¶

a tuple (pallet_name_bytes, Option<function_name_bytes>) to represent blocked extrinsics if Option<function_name_bytes> is None, then all extrinsics in pallet_name_bytes are blocked

Python¶

result = substrate.query(
    'ExtrinsicFilter', 'BlockedExtrinsics', [('Bytes', 'Bytes')]
)

Return value¶

()

Mode¶

current mode, ValueQuery as it can't be None

Python¶

result = substrate.query(
    'ExtrinsicFilter', 'Mode', []
)

Return value¶

('Normal', 'Safe', 'Test')

Errors¶

CannotBlock¶

Error when a given extrinsic cannot be blocked (e.g. this pallet)

CannotConvertToString¶

Error during conversion bytes to utf8 string

ExtrinsicAlreadyBlocked¶

Error when trying to block extrinsic more than once

ExtrinsicNotBlocked¶

Error when trying to unblock a non-existent extrinsic
