<div class="textblock"><p>Helper class: Per-thread logging information.</p>
<p>Multiple threads can easily clobber each others' half-done logging. A naive approach to prevent this would be to lock a mutex when a thread starts logging and unlock it when it's done logging. But that "when it's
done" condition might never come true. std::endl or a newline in the output stream would be one indication, but there is no way to make sure there always is such a delimiter. If it is forgotten and that thread (that still has the mutex locked) runs into a waiting condition itself (e.g., UI thread synchronization with pipes), there would be a deadlock.</p>
<p>So this much safer approach was chosen: Give each thread its own logging infrastructure, i.e., its own log stream and its own log buffer.</p>
<p>Sure, in bad cases the logger function might still be executed in parallel and thus clobber a line or two of log output. But that's merely bad output formatting, not writing another thread's data structures without control - which can easily happen if multiple threads are working on the same output buffer, i.e. manipulate the same string. </p>
