2020-12-15init: Signal-safe instant shutdownWladimir J. van der Laan
Replace the 200ms polling loop with a faster and more efficient waiting operation. This was tried a few times before, but given up every time because solutions use a condition variable which is not safe for use in signals as they need to be reentrant. On UNIX-ish OSes, use a safe way: a pipe. When shutdown is requested write a dummy byte to the pipe. Waiting for shutdown is a matter of a blocking read from the pipe. On Windows, there are no signals so using a condition variable is safe.
2018-06-25Break circular dependency: init -> * -> init by extracting shutdown.hBen Woosley
Most includers just wanted to react to pending shutdown. This isolates access to `fRequestShutdown` and limits access to the shutdown api functions, including the new `AbortShutdown` for setting it to `false`. Note I originally called `AbortShutdown` `CancelShutdown` but that name was already taken by winuser.h https://travis-ci.org/bitcoin/bitcoin/jobs/386913329 This change also triggered a build error in bench. Fixing it required moving LIBBITCOIN_SERVER after LIBBITCOIN_WALLET in bench_bench_bitcoin_LDADD To make server definitions in src/net.cpp available to wallet methods in src/wallet/wallet.cpp. Specifically, solving: libbitcoin_wallet.a(libbitcoin_wallet_a-wallet.o): In function `CWalletTx::RelayWalletTransaction(CConnman*)': wallet.cpp:(.text+0x3f0e): undefined reference to `CConnman::NodeFullyConnected(CNode const*)' collect2: error: ld returned 1 exit status https://travis-ci.org/bitcoin/bitcoin/jobs/392133581 Need for remaining init.h includes confirmed via a thorough search with a more specific regex: \bInterrupt\(\)|\bShutdown\(\)|\bInitLogging\(\)|\bInitParameterInteraction\(\)|\bAppInitBasicSetup\(\)|\bAppInitParameterInteraction\(\)|\bAppInitSanityChecks\(\)|\bAppInitLockDataDirectory\(\)|\bAppInitMain\(\)|\bSetupServerArgs\(\)|\bLicenseInfo\(\)|g_wallet_init_interface|init.h
