CommitSynchronizerInfo

class dsviper.CommitSynchronizerInfo

Bases: object

What a synchronization found.

Whether anything needs transmitting, what was fetched and pushed, and whether the definitions changed.

Note: Not directly instantiable.

fetch() → CommitSynchronizerInfoTransmit

Return information for fetched resources.

need_transmit() → bool

Return True if either side’s data_version() moved since the last sync.

When neither did, sync() compared and carried nothing. data_version() counts the writes made through other connections, so a commit written through a connection the synchronizer holds waits until another connection writes: give the synchronizer connections of its own.

push() → CommitSynchronizerInfoTransmit

Return information for pushed resources.

updated_definitions() → bool

Return True if the definitions has updated.
