Good work in progress. Next step would be to fix all the tests:

https://github.com/Groestlcoin/lightning/blob/master/tests/test_misc.py#L325
https://github.com/Groestlcoin/lightning/blob/master/tests/test_misc.py#L392-L444
https://github.com/Groestlcoin/lightning/blob/master/tests/test_pay.py#L479-L738
https://github.com/Groestlcoin/lightning/blob/master/tests/test_invoices.py#L20
https://github.com/Groestlcoin/lightning/blob/master/tests/test_invoices.py#L42

We don’t see an easy way to make Test code compatible with multiple currencies. So maybe adapt the tests just for GRS?

gruve-p · 2018-09-13T10:48:41Z

These need changes too:
msat to mgro
msatoshi to mgro
port 28332 to 21441

gruve-p · 2018-09-13T10:50:45Z

Maybe you should put the Hash function into ChainParams structure to make them dependant on Blockchain type?

dflate · 2018-09-13T11:52:13Z

yes!, some way to go.
i am the kind of type to think long to find an easy way with as less as possible lines
the fewer lines the more less wrong.

config files like LND does is ok with me.
and some global structure also.
but the whole design should be independent modules connected by sockets
so care must be taken to don't fill the garbage collection with leaks.

dflate · 2018-09-13T19:23:44Z

so far regtest,testnet and main tested 👍
with regtest you may have to use the perkw postfix
in the funding or pay command
ie fundchannel id@ip:port [amount] [fees]perkw

Good work in progress! Any chance you can fix the tests (#3 (comment)) ?

As we understand you are trying to solve the Bitcoin/Groestlcoin compatibility statically by macro “COMPILE_FOR_BITCOIN”. We should do it dynamically by hooks (global pointers to currency-dependent hash functions).

Also according to @ufasoft we should get rid of library libbase58, because it don’t allow to use Groestl hash function and put it's code into bitcoin/base58.c module.

So more changes are necessary in this PR.

dflate · 2018-09-14T08:07:29Z

the choice, i think is, do we make a multi coin multi algo c-lightning fork like LND
or do we single it out to plain c-grs-lightning?

the later is simple and clean, and easy to maintain and follow the ongoing dev.
like grs-core follows almost strictly core.
???

add global groestl flag to allow easy algo and name switch Signed-off-by: dflate <dflate@users.noreply.github.com>

gruve-p · 2018-09-14T10:20:13Z

After internal discussions we chose for simple and clean and easy to merge with upstream. We should maintain our own fork, so we will single it out to plain c-lightning-grs.

Our initial idea was to keep global pointer:

struct chainparams *g_chainparams;

typedef (void *PFN_HashAlgo)(struct sha256_double *shadouble, const void *p, size_t len);

struct chainparams {
…
PFN_HashAlgo
pfn_blockHash,
pfn_txHash;
};

Then all HashFunction-dependent C code should use functions g_chainparams-> pfn_blockHash() & g_chainparams-> pfn_txHash()

ok i just push a version that has almost all strings replaced and the lib in base58
!!!! totaly untested !!!! so please review

dflate · 2018-09-14T14:03:52Z

I now replaced all bitcoin and litecoin, and can still merge easy with ln/master.
.
So it's now plain c-grs-lightning.
!!! still untested !!!

dflate · 2018-09-14T15:52:58Z

please make sure if you use mainnet GRS coins, to backup the hsm_secret and the db file.after creation.
the actual ln/master implementation will overwrite the key and the database, if things in the filesystem go wrong at node startup.
I try to fix this here and in/master by demanding a user decision, for now
make sure you backup this file, otherwise the coins and channels are lost !!!!

c-lightning is still beta !!!

converting a block number to an scid truncates it at 24 bits. When we look through the index from (truncated number) to (real end number) we get every channel, which is too large to encode, so we iterate again. This fixes both that problem, and also the issue that we'd end up dividing into many empty sections until we get to the highest block number. Instead, we just tack the empty blocks on to then end of the final query. (My initial version requested 0xFFFFFFFE blocks, but the dev code which records what blocks were returned can't make a bitmap that big on 32 bit).

When we look through the index from (truncated number) to (real end number) we get every channel, which is too large to encode, so we iterate again. This fixes both that problem, and also the issue that we'd end up dividing into many empty sections until we get to the highest block number. Instead, we just tack the empty blocks on to then end of the final query. (My initial version requested 0xFFFFFFFE blocks, but the dev code which records what blocks were returned can't make a bitmap that big on 32 bit).

I'm deeply reluctant to do this, as I'd thought this was fixed with recent lnd versions. Logs below show that it continues, with channel loss on almost every restart. At this rate, we risk bifurcating the network. In fact, only four errors my node have ever been NOT "sync error". 2018-09-12T01:21:40.671Z lightningd(1263): 03e50492eab4107a773141bb419e107bda3de3d55652e6e1a41225f06a0bbf2d56 chan #3: Peer permanent

The variable `block` (instace of `struct block`) is allocated on the stack without being initialized, i.e. its member `prev` points to nowhere. This causes a segmentation fault on my machine on the binding of "prev_hash" on running `wallet_block_add`, as the following core-dump analysis shows: $ egdb ./wallet/test/run-wallet ./run-wallet.core [...] Core was generated by `run-wallet'.

It is possible for db_column_bytes() to return 0 and for db_column_blob() to return NULL even when db_column_is_null() returns false. We need to short circuit in this case.
