Detailed Description

Manages private module state that must be available during program startup and (especially) termination. Any non-trivial state objects must be encapsulated here because debugs() may be called before dynamic initialization or after the destruction of static objects in debug.cc.

Member Function Documentation

◆ banCacheLogUse()

void DebugModule::banCacheLogUse ( )

Start using stderr as the primary debugs() destination. Stop waiting for an open cache_log file (if we were doing that).

Definition at line 490 of file debug.cc.

References assert, cacheLogChannel, DebugFile::file(), stderrChannel, StderrChannel::takeOver(), and TheLog.

Referenced by Debug::BanCacheLogUse(), debugOpenLog(), prepareToDie(), and Debug::StopCacheLogUse().

◆ log()

void DebugModule::log ( const DebugMessageHeader header,
const CompiledDebugMessageBody body 
)

Log the given debugs() message to appropriate channel(s) (eventually). Assumes the message has passed the global section/level filter.

Definition at line 445 of file debug.cc.

References cacheLogChannel, DebugChannel::log(), stderrChannel, and syslogChannel.

Referenced by Debug::LogMessage().

◆ prepareToDie()

void DebugModule::prepareToDie ( )

Reacts to ongoing program termination (e.g., flushes buffered messages). Call this before logging the termination reason to maximize the chances of that valuable debugs() getting through to the admin.

Definition at line 453 of file debug.cc.

Referenced by Debug::PrepareToDie().

◆ useCacheLog()

void DebugModule::useCacheLog ( )

Start using an open cache_log file as the primary debugs() destination. Stop using stderr as a cache_log replacement (if we were doing that).

Definition at line 482 of file debug.cc.

References assert, cacheLogChannel, DebugFile::file(), stderrChannel, StderrChannel::stopCoveringForCacheLog(), DebugChannel::stopEarlyMessageCollection(), and TheLog.
