Member Function Documentation

bootstrapConfig()

virtual void RegisteredRunner::bootstrapConfig ( )

inlinevirtualinherited

Called right before parsing squid.conf. Meant for initializing/preparing configuration parsing facilities.

Reimplemented in NtlmAuthRr.

Definition at line 46 of file RunnersRegistry.h.

Referenced by SquidMain().

claimMemoryNeeds()

virtual void RegisteredRunner::claimMemoryNeeds ( )

inlinevirtualinherited

Called after finalizeConfig(). Meant for announcing memory reservations before memory is allocated.

Reimplemented in IpcIoRr, and MemStoreRr.

Definition at line 55 of file RunnersRegistry.h.

Referenced by RunConfigUsers().

create()

void SharedMemPagesRr::create ( )

overridevirtual

Implements Ipc::Mem::RegisteredRunner.

Definition at line 118 of file Pages.cc.

References Ipc::Mem::PageStack::IdForMultipurposePool(), Ipc::Mem::PagePool::Init(), Must, owner, Ipc::Mem::PageLimit(), PagePoolId, and Ipc::Mem::PageSize().

endingShutdown()

virtual void RegisteredRunner::endingShutdown ( )

inlinevirtualinherited

Called after shutdown_lifetime grace period ends and before stopping the main loop. At least one main loop iteration is guaranteed after this call. Meant for cleanup and state saving that may require other modules.

Reimplemented in Auth::CredentialCacheRr, ConnStateData, Dns::ConfigRr, and IdleConnList.

Definition at line 84 of file RunnersRegistry.h.

Referenced by SignalEngine::FinalShutdownRunners().

finalizeConfig()

virtual void RegisteredRunner::finalizeConfig ( )

inlinevirtualinherited

Called after parsing squid.conf. Meant for setting configuration options that depend on other configuration options and were not explicitly configured.

Reimplemented in sslBumpCfgRr, and MemStoreRr.

Definition at line 51 of file RunnersRegistry.h.

Referenced by SquidMain().

finishShutdown()

virtual void RegisteredRunner::finishShutdown ( )

inlinevirtualinherited

Definition at line 91 of file RunnersRegistry.h.

Referenced by RunRegistered(), SquidShutdown(), TestRock::tearDown(), and watch_child().

open()

void SharedMemPagesRr::open ( )

overridevirtual

called when the runner should open a previously created segment, not needed if segments are opened in constructor or init methods

Reimplemented from Ipc::Mem::RegisteredRunner.

Definition at line 128 of file Pages.cc.

References Must, PagePoolId, and ThePagePool.

startReconfigure()

virtual void RegisteredRunner::startReconfigure ( )

inlinevirtualinherited

Called after receiving a reconfigure request and before parsing squid.conf. Meant for modules that need to prepare for their configuration being changed [outside their control]. The changes end with the syncConfig() event.

Reimplemented in Dns::ConfigRr.

Definition at line 67 of file RunnersRegistry.h.

Referenced by mainReconfigureStart().

startShutdown()

virtual void RegisteredRunner::startShutdown ( )

inlinevirtualinherited

Called after receiving a shutdown request and before stopping the main loop. At least one main loop iteration is guaranteed after this call. Meant for cleanup and state saving that may require other modules.

Reimplemented in ConnStateData, and Rock::Rebuild.

Definition at line 78 of file RunnersRegistry.h.

Referenced by SignalEngine::doShutdown().

syncConfig()

virtual void RegisteredRunner::syncConfig ( )

inlinevirtualinherited

Called after parsing squid.conf during reconfiguration. Meant for adjusting the module state based on configuration changes.

Reimplemented in Auth::CredentialCacheRr, and PeerPoolMgrsRr.

Definition at line 71 of file RunnersRegistry.h.

Referenced by mainReconfigureFinish().

useConfig()

void SharedMemPagesRr::useConfig ( )

overridevirtual

Called after claimMemoryNeeds(). Meant for activating modules and features using a finalized configuration with known memory requirements.

Reimplemented from RegisteredRunner.

Definition at line 109 of file Pages.cc.
