After #15946 starting a pruned bitcoin-qt with blockfilterindex=1 will give the error message

Error: A fatal internal error occurred, see debug.log for details

It would be more helpful if it gave what's in the debug.log which is

basic block filter index best block of the index goes beyond pruned data. Please disable the index or reindex (which will download the whole blockchain agai

Background

The links to http. proto and annotations. proto no longer exist
Lower versions of GRPC may no longer work with existing code
I cannot access the public IP according to the documentation
Then I upgraded the GRPC to 1.36.0, the os-maven-plugin to 1.6.2, and the protobuf-maven-plugin to 0.6.1, everything was fine

Problem:

A common pattern is:

GUARD(s2n_stuffer_skip_write(stuffer, bytes_to_write));
uint8_t* ptr = suffer->blob.data + stuffer->write_cursor - bytes_to_write;

which could be simplified.

Solution:

*ptr could be an *out parameter to s2n_stuffer_skip_write

  • Does this change what S2N sends over the wire? No.
  • Does this change any public APIs? No.

Clients that support multiple server connections would like to have a way to decide which server connection is best able to handle a query. Servers currently "sort of" expose their load as fees, but there's no real exposure of server load in a useful way. Some parameter should be added to the "server" publication stream that clients can just compare across servers to decide which is most likely to

HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on effective use of ciphertext packing techniques and on the Gentry-Halevi-Smart optimizations.
