do you know where std::mt19937_64 from?
I see it at EthashCPUMiner.cpp, "static std::mt19937_64 s_eng((utcTime() + std::hash<decltype(tid)>()(tid)));" but haven't found this class
Paweł Bylica
@chfast
@tiendq #include <random>
Tien Do
@tiendq
wow, its name in reference document is std::mersenne_twister_engine, not cryptic mt19937_64, that's why I didn't find it :(
thanks
Tien Do
@tiendq
what's reason to call setWork, start, and setWork again here? https://github.com/ethereum/aleth/blob/master/libethashseal/Ethash.cpp#L241
Tien Do
@tiendq
@chfast is there any instruction to run unit tests?
Tien Do
@tiendq
e.g. I want to run just some specific tests

Hi @CoreTeam, sorry for bother you. Who can guide me the code details about how transaction execute in Every Ethereum Full Node?

how can I change the data dir for aleth?

oh wow cpp got a rebrand to Aleth? nice =)

@tiendq
is there anyone running cpp-ethereum on Windows?
Andrei Maiboroda
@gumb0
@tiendq yes, I am
Tien Do
@tiendq
@gumb0 how can it? I just knew leveldb doesn't support Windows yesterday from a Github issue, and you have also opened a ticket for RocksDB
Paweł Bylica
@chfast
We are using Bitcoin's fork of leveldb, not upgraded for years.
That's an issue. My proposed solutions to this is to switch to rocksb.
Mamy Ratsimbazafy
@mratsim
Note that Parity is using RocksDB, they were scheduled to talk for ECDC Berlin but unfortunately couldn’t :/ They wouldn’t to create their own blockchain specialized solution (since blockchain DB are append-only there are several opportunities for optimization there).
Tien Do
@tiendq
@chfast thanks for your info
Tien Do
@tiendq
is there any way I can unit test some code in aleth (executable project)?
I don't see a test project for it under tests/unittests
Tien Do
@tiendq
@chfast does cpp-ethereum implement PoA?
Mamy Ratsimbazafy
@mratsim
@tiendq the tests live there: https://github.com/ethereum/tests
Tien Do
@tiendq
@mratsim I know it, I asked specifically for tests of aleth executable module. Does it exist?
Mamy Ratsimbazafy
@mratsim
ah you want to test the executable
Tien Do
@tiendq
actually aleth executable file doesn't have many things to unit test, but when we refactor some functions, fix some issues etc. it's better to be able to test it
we can move changes to an existing lib., which already covered by unit tests, I think it's an option :)
Paweł Bylica
@chfast
@tiendq We have unit tests in test/unittests. Nothing for CLI though if that's what you mean
Tien Do
@tiendq
@chfast yes, it was what I wanted to know. It's confirmed now, thanks :)
Paweł Bylica
@chfast
We renamed ethereum/cpp-ethereum room to ethereum/aleth. I think we should close this one because very much activity here. @/all

hey all! I'm hoping to get started contributing to this project. One thing I've noticed off the bat, is that the coding standard spec (https://raw.githubusercontent.com/ethereum/cpp-ethereum/develop/CodingStandards.txt) is currently a 404
Also, what's the activity like on this project? Seems like a long time since anyone has been around!
Paweł Bylica
@chfast
Hi, we are around...
Alex Beregszaszi
@axic
@chfast is there a stable aleth release which supports “petersburg”?
Paweł Bylica
@chfast
No
Alex Beregszaszi
@axic
it has constantinopleFixForkBlock, not sure if it was released yet.
