    Add missing locks required when accessing:

    0int32_t nBlockSequenceId GUARDED_BY(cs_nBlockSequenceId) = 1;
1int nLastBlockFile GUARDED_BY(cs_LastBlockFile) = 0;
2bool fCheckForPruning GUARDED_BY(cs_LastBlockFile) = false;
3CuckooCache::cache<uint256, SignatureCacheHasher> scriptExecutionCache GUARDED_BY(cs_main);
4BlockMap& mapBlockIndex GUARDED_BY(cs_main);
5std::unique_ptr<CCoinsViewDB> pcoinsdbview GUARDED_BY(cs_main);
6std::unique_ptr<CCoinsViewCache> pcoinsTip GUARDED_BY(cs_main);
7std::unique_ptr<CBlockTreeDB> pblocktree GUARDED_BY(cs_main);

    Also, add the locking annotations that follow from the requirements above.

    Please just put a cs_main at the top of the load-from disk loop thing, there is no reason to lock and unlock cs_main 20 times during single-threaded init.

    General note: Instead of documenting the locking assumptions in the OP of this pull request, wouldn’t it be better to put them in the header files? Imo, this increases review efficiency.

    @MarcoFalke You mean as an interim before we’ve added GUARDED_BY(…) annotations for each guarded variable?

    I can’t force push 7e11716932b8a1f6f1aa2c06e1990b64950a89bc to your branch either, since the pull request is closed.

    Try

    0git push origin 7e11716932b8a1f6f1aa2c06e1990b64950a89bc:init-and-validation-locks -f
1# reopen
2git push origin init-and-validation-locks -f

    @MarcoFalke I’m a bit unsure how to resolve the locking errors below (see Travis OS X output). Do you have any suggestion?

    If m_wallet.chain().lock(…) succeeds then we have acquired cs_main and access to chainActive should be OK?

    0interfaces/wallet.cpp:335:22: error: reading variable 'chainActive' requires holding mutex 'cs_main' [-Werror,-Wthread-safety-analysis]
1        num_blocks = ::chainActive.Height();

    The compiler doesn’t understand that, though. You’d have to add a temporary annotation or use the interface (c.f. #14711)

    re: #11652 (comment)

    I’m a bit unsure how to resolve the locking errors below (see Travis OS X output). Do you have any suggestion?

    You could use the LockAnnotation class to resolve these errors. See 081accb875412f38718f2e40ed7bbdf15e6f4ef8 from #14437 for examples. Rebasing on top of #14711 would also resolve them.

    @MarcoFalke Would you mind taking over this PR if it put it up for grabs? At the moment I’m afraid I don’t have time to resolve the remaining issues.

    At the moment I’m afraid I don’t have time to resolve the remaining issues.

    Are there other issues besides the need for lock annotations in the wallet? If not, we could just treat this PR as blocked until #14711 is merged, since it removes the need for them.

    Closing in favour of PR #15191 and #15192. They cover everything in this PR except the chainActive locks.

    I’ll revisit the missing cs_main locks required for chainActive once #14711 is merged.
