33 | /* @todo
|
---|
34 | * We have two ways of saving/loading states.
|
---|
35 | *
|
---|
36 | * First which is being used atm, just pure saving/loading of structures.
|
---|
37 | * The drawback is we have to deal with all the pointers around those structures,
|
---|
38 | * we'd have to update this code if we'd change state tracking.
|
---|
39 | * On the bright side it's fast, though it's not really needed as it's not that often operation.
|
---|
40 | * It could also worth to split those functions into appropriate parts,
|
---|
41 | * similar to the way context creation is being done.
|
---|
42 | *
|
---|
43 | * Second way would be to implement full dispatch api table and substitute diff_api during saving/loading.
|
---|
44 | * Then if we implement that api in a similar way to packer/unpacker with a change to store/load
|
---|
45 | * via provided pSSM handle instead of pack buffer,
|
---|
46 | * saving state could be done by simple diffing against empty "dummy" context.
|
---|
47 | * Restoring state in such case would look like unpacking commands from pSSM instead of network buffer.
|
---|
48 | * This would be slower (who cares) but most likely will not require any code changes to support in future.
|
---|
49 | * We will reduce amount of saved data as we'd save only changed state parts, but I doubt it'd be that much.
|
---|
50 | * It could be done for the first way as well, but requires tons of bit checks.
