Authored by Ryan Ofsky
doc: Improve dependencies.md IPC documentation
Improve dependencies.md to document IPC dependencies better:
- Link to native_capnp.mk file not capnp.mk file so it's possible to see what
version of Cap'n Proto is being used in release binaries. This is important
since #31895 dropped the "Version Used" column and the capnp.mk file does not
include version number.
- Indicate Capn"Proto is used for IPC and link to multiprocess.md documenting
the feature.
- Link to correct PR requiring Cap'n Proto 0.7.1. Previous link was
pointing at PR which required 0.7.0.
- Mention libmultiprocess as a dependency even though it is included as a git
subtree and can be built as a cmake subproject. Libmultiprocess still needs
to be built separately when cross compiling, and is useful to build separately
when developing, and is still a depends package.
Based on 2cf352fd8e6a77003e38d954b6c879b20d4b960a from #33623 by willcl-ark
which made similar changes in the 29.x branch.
What changed, and why it matters
This commit is a documentation-only update to the Bitcoin Core dependencies guide. It fixes links, adds a missing dependency entry for libmultiprocess, and clarifies that Cap'n Proto is used for inter-process communication (IPC). No code was changed, so there is no direct security impact.
No security action required. Review as normal documentation change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies doc/dependencies.md only. It updates the Cap’n Proto link from depends/packages/capnp.mk to native_capnp.mk, adds an IPC cross-reference to multiprocess.md, corrects the PR link for the 0.7.1 minimum version requirement from PR #28907 to PR #33241, and adds a new row documenting libmultiprocess (native_libmultiprocess.mk) with a link to its tags and minimum version v7.0-pre1 from PR #33517. No executable code, build scripts, or dependency versions are changed.
