feat(zcoin): allow ARRR/ZCOIN compilation in wasm #1805

borngraced · 2023-05-05T04:20:01Z

This PR allows ARRR to be compiled in WASM.
After this PR, I will start implementing the empty/todo fn and storages

Thank you for starting this important feature! First review iteration.

+#[cfg(not(target_arch = "wasm32"))]
 pub struct BlockDb(Connection);
+#[cfg(target_arch = "wasm32")]
+pub struct BlockDb(String);

+#[cfg(not(target_arch = "wasm32"))]


please follow BlockHeaderStorageOps example https://github.com/KomodoPlatform/atomicDEX-API/blob/d01dd41e91ccf7e353a4cdb4e2135bdeb8dfc3de/mm2src/mm2_bitcoin/spv_validation/src/storage.rs#L87
by creating a common trait that should be implemented for both struct BlockDb(Connection) and pub struct BlockDb(String);. Shouldn't pub struct BlockDb(String); use IndexedDb and not a String ? You can change these structs as you see fit.

To start with, I use obvious string just to make WASM build pass as I wouldn't want to implement the storages. structure in this pr to not look messy or too complex to review.

BlockDb can't be implemented like the way BlockHeaderStorageOps is done because BlockDb additionally needs to implement a trait with a generic function.
https://github.com/KomodoPlatform/atomicDEX-API/blob/46535e882896e10aa16f3d6364007ba2a8c0cc3d/mm2src/coins/z_coin/z_rpc.rs#L363-L372

which makes doing these impossible with the current rust

Meanwhile, I already completed the implementation structure in another branch, so I got it covered 💯

Meanwhile, I already completed the implementation structure in another branch, so I got it covered

May be it worth adding this implementation in this PR with todos if you have it? So we can see the whole picture.

Ok cool, after Omar's comment

BlockDb can't be implemented like the way BlockHeaderStorageOps is done because BlockDb additionally needs to implement a trait with a generic function.

BlockDb can implement multiple traits, I don't see the problem. It doesn't have to be exactly like BlockHeaderStorageOps/BlockHeaderStorage but I meant to take it as an example. Another example is the LightningDB trait which I plan to implement for IndexedDB later and have a common interface. https://github.com/KomodoPlatform/atomicDEX-API/blob/a1fc8f7c92819f68c0dcdf7b1c650d86cdf945ad/mm2src/coins/lightning/ln_db.rs#L200

May be it worth adding this implementation in this PR with todos if you have it? So we can see the whole picture.

As discussed with @borngraced on DM, he will add them to this PR, as for the above suggestion about following BlockHeaderStorageOps/LightningDB/etc.. you can try that in the next PRs since it will be tricky dealing with generics.

-        let db = self.z_fields.light_wallet_db.clone();
+    #[cfg(target_arch = "wasm32")]
+    async fn my_balance_sat(&self) -> Result<u64, MmError<ZCoinBalanceError>> { todo!() }


my_balance_sat wasm implementation shouldn't return a different error from the native implementation. I understand that ZcashClientError is SqliteClientError, please consider implementing a common error type for both wasm and native implementation in the next PR, you can then implement From this new error type for SqliteClientError, etc..
I guess having a common interface as discussed here #1805 (comment) helps in this.

yes I understand 💯 that was always the plan

LGTM at this stage! Only some minor non-blocker comments!
@borngraced please don't forget to add some unit tests for IndexedDb implementations in the next PRs.

@laruh please do a final review of this when you can.

IndexedDBError should probably be for wasm target only too

shamardy · 2023-05-31T16:51:29Z

@borngraced please fix the PR title to make it inline with conventional commits :)

laruh

LGTM! Thanks for your work!
I have some non blocker notes and suggestions for next PR.

In next implementations may be there is a need in trait Ops for BlockDbImpl, to impl common fns like get_latest_block, insert_block, rewind_to_height etc for two targets.
And perhaps it is worth separating the database implementations for different targets into different modules (I mean not to keep both of them in mod.rs). Lets see.

yeah, you're right... my comment to Omar here is related to this too #1805 (comment)
