+
+			// TODO: Assuming this is one read

This .iter().count() already reads all of the Calls from storage. They won't be re-read from the DB when you drain below, but is an avoidable overlay storage access.

I'd just use let mut call_reads = 0u32 and mutate it in the drain.

Looks broadly good, do you have any run outputs on kusama/polkadot? based on how many ongoing multisigs we have there, how big this migration is?

kianenigma · 2022-09-20T16:26:19Z

@ggwpez recently mentioned that using try-runtime on-runtime-upgrade with --sync=warp is quite viable, perhaps that would help you.

Not yet, will check with try-runtime precheck I guess.

You can do a drain().collect() to store all calls into a variable. Then you can use then length as storage reads.

ggwpez · 2022-09-25T10:21:54Z

frame/multisig/src/migrations.rs

+
+			// TODO: Assuming this is one write and a read per record
+			Calls::<T>::drain().for_each(|(_call_hash, (_data, caller, deposit))| {
+				//TODO: What's the weight of one unreserve?


Sadly nobody knows since a lot of traits are missing weight info.

+		#[cfg(feature = "try-runtime")]
+		fn post_upgrade() -> Result<(), &'static str> {
+			let onchain = Pallet::<T>::on_chain_storage_version();
+


Could you add an assertion that the new version is exactly 1?

Yeah, the assertion we have now is wrong, about to fix it.

ggwpez · 2022-09-25T10:30:54Z

frame/multisig/src/lib.rs

+
+// syntactic sugar for logging.
+#[macro_export]
+macro_rules! log {


Why is this in here if you only use it in the migration?

Because I'd rather define logging macro for the whole package and have the opportunity to use it when/if needed. It's also consistent with other pallets which define logging.

@ruseinov's point is fair to me, I had to do the same in the past.

@ggwpez what I challenge you about is a way so we won't need to define this log macro per-pallet? wdyt?

ruseinov · 2022-09-28T10:11:53Z

This needs to be tested with try-runtime to see if we need any sort of batching, but it seems like the latest substrate master is not compatible with polkadot, so I'm going to retry this in the coming days.

@kianenigma @ggwpez
tried that on a couple weeks old snap on pdot, seems like this migration with MaxWeight definitely works and even is an overkill:

to be pedantic, we could add some math here that: if the number of calls is so much that this exhausts block weight, abort or log a warning.

Or just have a limit configurable limit (eg 100) which can then be tested with try-runtime in advance to respect the limits.

kianenigma

LGTM.

Merging this, please continue reviewing this in the parent PR: #12072

shawntabrizi · 2022-09-29T15:40:54Z

im not a fan that this PR doesnt have a clear description, reasoning, follow up actions, and stuff...

do you assume everyone affected by this will just read code? or that code represents why things are happening?
