Function Documentation

AppInitBasicSetup()

bool AppInitBasicSetup

(

)

Initialize bitcoin core: Basic context setup.

Note

This can be done before daemonization. Do not call Shutdown() if this function fails.

Precondition

Parameters should be parsed and config file should be read.

AppInitLockDataDirectory()

bool AppInitLockDataDirectory

(

)

Lock bitcoin core data directory.

Note

This should only be done after daemonization. Do not call Shutdown() if this function fails.

Precondition

Parameters should be parsed and config file should be read, AppInitSanityChecks should have been called.

AppInitMain()

bool AppInitMain

(

InitInterfaces &

interfaces

)

Bitcoin core main initialization.

Note

This should only be done after daemonization. Call Shutdown() if this function fails.

Precondition

Parameters should be parsed and config file should be read, AppInitLockDataDirectory should have been called.

AppInitParameterInteraction()

bool AppInitParameterInteraction

(

)

Initialization: parameter interaction.

Note

This can be done before daemonization. Do not call Shutdown() if this function fails.

Precondition

Parameters should be parsed and config file should be read, AppInitBasicSetup should have been called.

AppInitSanityChecks()

bool AppInitSanityChecks

(

)

Initialization sanity checks: ecc init, sanity checks, dir lock.

Note

This can be done before daemonization. Do not call Shutdown() if this function fails.

Precondition

Parameters should be parsed and config file should be read, AppInitParameterInteraction should have been called.

AppInitServers()

static bool AppInitServers ( )

static

BlockNotifyGenesisWait()

static void BlockNotifyGenesisWait ( bool  , const CBlockIndex *  pBlockIndex  )

static

CleanupBlockRevFiles()

static void CleanupBlockRevFiles ( )

static

CreatePidFile()

static NODISCARD bool CreatePidFile ( )

static

GetPidFile()

static fs::path GetPidFile ( )

static

HandleSIGHUP()

static void HandleSIGHUP ( int  )

static

HandleSIGTERM()

static void HandleSIGTERM ( int  )

static

Signal handlers are very limited in what they are allowed to do. The execution context the handler is invoked in is not guaranteed, so we restrict handler operations to just touching variables:

InitLogging()

void InitLogging

(

)

Initialize the logging infrastructure.

Initialize global loggers.

Note that this is called very early in the process lifetime, so you should be careful about what global state you rely on here.

InitParameterInteraction()

void InitParameterInteraction

(

)

Parameter interaction: change current parameters depending on various rules.

InitSanityCheck()

static bool InitSanityCheck ( )

static

Sanity checks Ensure that Bitcoin is running in a usable environment with all necessary library support.

Interrupt()

void Interrupt

(

)

Interrupt threads

LicenseInfo()

std::string LicenseInfo

(

)

Returns licensing information (for -version)

LockDataDirectory()

static bool LockDataDirectory ( bool  probeOnly )

static

new_handler_terminate()

static void new_handler_terminate ( )

static

OnRPCStarted()

static void OnRPCStarted ( )

static

OnRPCStopped()

static void OnRPCStopped ( )

static

registerSignalHandler()

static void registerSignalHandler ( int  signal, void(*)(int)  handler  )

static

ResolveErrMsg()

static std::string ResolveErrMsg ( const char *const  optname, const std::string &  strBind  )

static

SetupServerArgs()

void SetupServerArgs

(

)

Setup the arguments for gArgs

Shutdown()

void Shutdown

(

InitInterfaces &

interfaces

)

Note: Shutdown() must be able to handle cases in which initialization failed part of the way, for example if the data directory was found to be locked. Be sure that anything that writes files or flushes caches only does this if the respective module was initialized.

ThreadImport()

static void ThreadImport ( std::vector< fs::path >  vImportFiles )

static
