better to ask in #bitcoin, this is not a support but a development channel, read the topic please
< Randolf>
Guest89357: For support, the #bitcoin channel is probably your best bet.

I have a problem related to an old bitcoin core client
< Randolf>
Guest89357: There are many active folks here, but the discussions are usually focused on the development of the various facets of the Bitcoin project.

kallewoof: bitcoin core doesn't rebroadcast third party txn, but random bozos do, because they think they're helping in some cases, or because they want to pump up mempool stats. or god knows why

Provoostenator: well my concern is ux for average users...if I'm sending to someone I know understands bitcoin, fine, no issue, if its some guy who's receiving a withdraw from an atm/their exchange, they may be very confused

no need to relay it in bitcoin p2p net?

alcipir: My suggestion is to learn C++ first, and then learn about programming Bitcoin/blockchain. The reason is that both have learning curves that are probably better-studied separately.

Or you could stalk your friends with C++ skills and manipulate them into becoming interested in Bitcoin, quitting their current job and helping out :-)

I have a Bitcoin Core wallet.dat which I've had forever. Today, I made a fresh wallet.dat, created a receive address and went back to the original wallet.dat and transferred almost all of the Bitcoins to the new one, for the sake of being able to safely "claim" Bitcoin Gold/Cash/whatever without risking that the software just steals my Bitcoin instead of giving me other coins (and also to put the new wallet.dat in offline storage....

currently if you define e.g. port or bind in bitcoin.conf you will get collisions when you run both testnet and mainnet on the same machine
< meshcollider>
one idea I had was suggested in https://github.com/bitcoin/bitcoin/pull/10996#issuecomment-346189099, basically we default to using root-level bitcoin.conf and network specific network.conf if they exist, but if -conf is specified then we just use that and not the network specific one too

(there's a similar consideration on whether to do flto on just bitcoin core or all the dependencies as well. Though that experiment was put on hold when it turned out flto somehow negatively affected performance, at least in a specific case)

none of the dependencies that are not built into bitcoin's source tree are performance critical (maybe with the exception of boost, but that's mostly header only?)

hm, right. so I guess that L1289-1290 in bitcoin's configure.ac would be where to pass through the config flags to secp256k1: AC_CONFIG_SUBDIRS([src/secp256k1])
< wumpus>
the only documentation of it is in ./configure. secp256's configure at that, not bitcoin's.

I guess I'll try linking directly and see how far that gets me. I suspect there will be a lot of issues where the bitcoin code expects a fully fledged bitcoin instance running.
< kallewoof>
Hum. I could avoid a lot of reinventing wheels by simply requiring libbitcoin_[x].a in the indexer to link p2p stuff in. Potential minefield, but would be super easy to keep up to date with bitcoin core if it worked.
< kallewoof>
And yeah, we agreed this should be an external thing that either uses hooks in bitcoin or implements the p2p protocol and talks to the network directly.

esotericnonsense: For Bitcoin stuff, I'd create custom datatypes that save the data in binary format.
< kallewoof>
I think having hooks in bitcoin core that let such a system exist separately is a good plan. It would only rely on API breakage, which bitcoin core is very careful about.

I've been asked about address index on top of bitcoin core (to replace the unmaintained fork that exists somewhere else). What are people's opinions on this? I know some people prefer a minimal code base, but having an address index option seems like it would alleviate a lot of problems in a lot of places.

I believe bluematt wrote a very small patch to change bitcoin to poll. We could take, that and wrap it in ifdefs so we still select on windows, and call that sub-issue done.
