+func (am AppModule) BeginBlock(ctx sdk.Context, _ abci.RequestBeginBlock) {
+ // TODO should we emit an event for this?
+ am.keeper.DeleteExpiredApplicationLinks(ctx)


should we emit some events for this?

Yes, we should emit one event for each deleted link. I don't know whether it would be better to do this here or inside the DeleteExpiredApplicationLinks method though

I think we can follow how we did with other keeper's methods and put it inside the DeleteExpiredApplicationLinks method.

+ DefaultMinDTagLength = sdk.NewInt(3)
+ DefaultMaxDTagLength = sdk.NewInt(30)
+ DefaultMaxBioLength = sdk.NewInt(1000)
+ DefaultAppLinksExpirationTime = time.Hour * 24 * 7 * 4 * 6 // This duration is equal to roughly 5.5 months time in minutes 241920


I took the DefaultUnbondingTime param as an example:
https://github.com/cosmos/cosmos-sdk/blob/6ea204994443edc7841df4f0dc86ee5b4edc8377/x/staking/types/params.go#L21.

The expiration time default param is a duration of time of roughly 6 months.
Why roughly? Because not all months last the same.
So basically:
DefaultExpirationTime = 241920 minutes -> 5.5 months -> 168 days.

It's not a definitive default param, I would like to discuss with you what should be a reasonable amount of time before a link expires. IMO, it should not be less than 3 months.

We can set it to be 4382.91 hours considering one mean year has 8765.82 hours (see here). This could give us the duration closes to 6 months

Since we can't sum decimals in time params calculation I've added an ExpirationTimeCorrectionFactor that I calculated as follow:

4382.91 hours are 182 days;

DefaultAppLinksExpirationTime were 168 days;

182 - 168 = 14 days = 20160 minutes;

DefaultAppLinksExpirationTime + 20160 minutes = 262080 = 5.9835 Months.

This workflow uses benchstat a common go tool for comparing different benchmarks results.
In our case, the workflow will compare the master branch benchmark's result with the ones of a new PR which is IMO very useful to let us understand if we have introduced a performance regression.
In order to make this properly working, bench tests should be written when we consider it's the case.

I've updated all the code and how the migrations are handled to work best. I would like to ask @dadamu to review the code and also fix the now failing test (it's always the one related to the JSON within the profiles module). Once that's done I think we can merge this

This method is out of keeper range, it would be better to have a specified function like DeleteExpiredApplicationLinks.

I've moved it to be inside the profiles package as it should be (since it's testing the BeginBlocker method). I removed the DeleteExpiredApplicationLinks as in my opinion it was pointless to have that method only so that we could write benchmark tests when we could simply have done it this way

+func (m Migrator) Migrate6to7(ctx sdk.Context) error {


I am confused the version, v6.MigrateStore is actually migrating to v6 from v5 although the method is called Migrate6to7. Is that consensus version different from legacy store version?

That was actually an error within comments themselves. I've now updated them to make it more clear. Generally, the Migrate<X>to<X+1> calls the v<X> package that handles the migration from X to X+1 properly. So in this case Migrate6to7 calls the v6 package that migrates from 6 to 7 (latest version).

The only thing wrong here was the comment on the v6.MigrateStore function. It migrates from 6 to 7 (and not 5 to 6 as it was written). I've now fixed it

@RiccardoM Thanks for the explanation. But it would be another problem that v6.MigrateStore actually migrates v5types to the current type v6 like this.

Yeah, that is because inside the migration from v5 to v6 the types didn't change. So now we have to migrate from v5 to v7 (current version). I've updated the comments to make this more clear

Another question related to version. Should we set the version here to consensus version? e.g., desmos.profiles.v7.AddressData.

As well as the query route. To be like /desmos/profiles/v7/profiles/{user}

No, these types should reflect the Protobuf versioning (which is different from the module consensus versioning). We should update them only when we change the Protobuf definitions, as they change less often than the module consensus version (see from v4 to v5 where we didn't change a single Protobuf version but we had to do a migration to add new keys)
