Note each defer occurs a 30ish ns overhead here, which is significant
for IAVL iteration. We were previously using around 3-4 defers. (2 in
next, one in Valid, one in Key, one in Value) This slows down the entire
application quite significantly, as we require fast iteration.
* Adds a Min function to Int, and uses that in the slash function
* Adds a getHeight helper function to iavlstore
* Adds a splitPath function to baseapp
* Changes cyclo param from 10 to 11
* tools: Add unparam linter
unparam detects unused parameters in functions, and a parameter to
a function which only ever takes on one value. The latter is an
indication that more tests are required.
There are many nolints in this PR, as I believe that writing tests
to fix alot of these situations is out of scope for this PR / it
will be changed in future commits. There are some nolints for
when we have to comply to normal api's.
* crypto/keys no longer used by x/gov/client/rest/rest.go
Merges the keybase and Ledger code from go-crypto (which is no more) into the SDK
Adds support for Ledger into gaiacli
Cherry-picks updated error handling from #1158
I removed that stuff about cwwMutex and CacheWraps expiring. It was unnecessary complexity given that users need not write concurrent logic. If you have 2 CacheKVStores and you Write on one and later you Write on the other one, they will both write, and strange things may happen. But that’s OK, it’s kinda the expected (unsurprising) behavior. And now the code is much simpler.
Also I got rid of IterKVStore. It’s not necessary to distinguish them because we can have KVStore.Iterator() return nil or panic or an empty iterator. Further simplification…
KVStore.CacheKVStore() doesn’t exist. No need, just call NewCacheKVStore(parent).
Originally I wanted the .CacheKVStore() method because you can make the implementor be responsible for ensuring that returned CacheWraps don’t trample each other. But as written previously this complicates the code a lot more and it isn’t strictly necessary. It’s a kind of magic that maybe should just be avoided.
sdk.Iterator is dbm.Iterator. The plan is to conservatively add more aliases into the “sdk” namespace.
GetError() is removed from Iterator. We need to just panic to be consistent. More simplification.
