[29.x] More backports #32810

fanquake · 2025-06-25T10:41:11Z

Backports:

Nix patches cmake to remove the root directory `/` from `CMAKE_SYSTEM_PREFIX_PATH`: https://github.com/NixOS/nixpkgs/blob/428b49b28ebc8938a6d9f6c540d32d7a06713972/pkgs/by-name/cm/cmake/001-search-path.diff#L10 Without this, and when using the toolchain for depends builds, cmake's `find_path()` and `find_package()` do not know where to find dependencies, causing issues like: bitcoin#32428 Adding this path back via CMAKE_PREFIX_PATH is harmless on other systems, and fixes the toolchain for Nix users. We append the `/` dir a maximum of once, as the toolchain may be called repeatedly during builds.

The catchup loop in the outbound eviction functional test currently has a small flaw, as the contained waiting for a `getheaders` message just waits for any such message instead of one with the intended block hash. The reason is that the `prev_prev_hash` variable is set incorrectly, since the `tip_header` instance is not updated and its field `.hash` is None. Fix that by updating `tip_header` and use the correct field -- we want the tip header's previous hash (`.hashPrevBlock`). Github-Pull: bitcoin#32742 Rebased-From: dd8447f

ACK e96d360

Verified that the correct commits are being pulled in and the release notes.

According to the CMake documentation, `HINTS` "should be paths computed by system introspection, such as a hint provided by the location of another item already found", which is precisely the case in the `FindQRencode` module. Entries in `HINTS` are searched before those in `PATHS`. On macOS, Homebrew’s `libqrencode` will therefore be located at its real path rather than via the symlink in the default prefix.

On macOS, this change ensures that the Boost package is located at its real path rather than via the symlink in the default prefix. Github-Pull: bitcoin#32814 Rebased-From: 8800b5a

Tested on M4 macOS 15.5 that with 5987c1b having qt5 and qt6 (qt@5 and qt via Homebrew) leads to the issues described in #31009, but with fe8034b it's happy.

Will test on Intel later.

The fix also works on Intel with macOS 13.7.6

hebasto

ACK fe8034b. I've backported all mentioned PRs locally and got zero diff with this branch.

32-bit architecture is limited to 4GiB, so it doesn't make sense to set a too high value. 500 MB is chosen as an arbitrary maximum value that seems reasonable. Github-Pull: bitcoin#32530 Rebased-From: 2c43b6a

32-bit architecture is limited to 4GiB, so it doesn't make sense to set a too high value. Since this setting is performance critical, pick an arbitrary value higher than for -maxmempool but still reasonable. Github-Pull: bitcoin#32530 Rebased-From: 9f8e7b0

ACK ef2a013

Build on macos/arm64 after experiencing issues locally building a checked-out v29.0 GUI with only qt 6 installed. Can confirm these backports solve that problem and GUI runs fine. Did not test the other backports.

@josibake / @hebasto want to re-review?

hebasto

re-ACK ef2a013.

Missed credits to @darosior and @ryanofsky?

willcl-ark

ACK ef2a013

...modulo hebasto's comments.

Backports all look correct.

fanquake · 2025-07-03T10:56:18Z

There's going to be another branch, so any credits can be fixed up there.
