build.rs: patch out any calls to `printf` 2023-11-01 17:34:21 +00:00
Davidson Souza 39febcb866
Create rust-bidings
Create bindings for all methods and static types in ellswift.h in
secp256k1-sys and their respective safe-rust types.

All methods are extensively commented and tested using BIP324's
test vectors

Introduce SPDX license identifiers
Licenses are boring as hell, so is are all the comments at the top of
each file. This patch makes no comment on the merit of license comments
in each file, rather this patch reduces the license comment to the
minimum possible with no loss of meaning - an SPDX license identifier.

Note also please that we remove the "written by" comments as well for
the following reasons (discussed recently on rust-bitcoin repo):

- they are not descriptive because many devs contributed
- they have a tendency to include the wrong date because of cut'n'pasta
- all this info is in the git history

secp256k1-sys: Remove unused flags in build.rs 2022-11-24 13:38:40 +02:00
Matt Corallo 92b733386f Support non-WASM platforms that are missing `string.h`
Dunno why we haven't seen this elsewhere, but when trying to build
locally for an ARM embedded target `secp256k1-sys` failed to
compile as it was missing `string.h`, just like WASM.

This patch adds a trivial fallback - if we fail to compile
initially we unconditionally retry with the wasm-sysroot, giving us
a valid `string.h`.

Tobin Harding bfd88dbd6c Move WASM const definitions to a source file
Currently we are defining the WASM integer size and alignments in the
`stdio.h` header file, this is wrong because this file is included in
the build by way of `build.rs` as well as by upstream `libsecp256k1`.

Move WASM integer definitions to a `C` source file and build the file
into the binary if target is WASM.

Andrew Poelstra 8294ea3f50 secp256k1-sys: update upstream library
Two API changes needed to be reflected: schnorrsig_sign and schnorrsig_verify.

Also bump both Cargo.toml files

Matt Corallo ee1103a1f3 Reduce visibility on secp-sys symbols
cc-rs builds C dependencies with reduced visibility to avoid
exporting the C symbols all the way out to any rust-built shared
libraries however we override it with SECP256K1_API. We should
avoid doing this, allowing LTO/DCE to do its work.

Andrew Poelstra d77483f00e replace cargo `external-symbols` feature with a rustc --cfg flag
This feature was not useful for Cargo users, since Cargo does not give you
the kind of fine-grained control over C library linkage that you need. So
it was just unnecessarily confusing and would cause the build to break if
you enabled it accidentally, say, with --all-features.

Tim Ruffing 489e3ff8d2
Define ECMULT_GEN_PREC_BITS
This is configurable in upstream now.

Fixes #214.

So far, this just sets it to `4`. It's tempting to set it to `2` when `lowmemory` is enabled
but `lowmemory` is about RAM and not about binary size. This is better addressed by
a resolution of #193.

Matt Corallo d9d398ccc9 Re-support WASM via simple stub headers
libsecp256k1 really only barely uses libc at all, and in practice,
things like memcpy/memcmp get optimized into something other than a
libc call. Thus, if we provide simple stub headers, things seem to
work with wasm-pack just fine.

Add external-symbols feature to support external libsecp
This feature disables using the bundles sources and will link into
existing libsecp256k1 symbols.
