Hello, I have a question about this:
commitLeastPages and writePos - lastCommittedPosition are two-dimensional
variables，why this judgment can achieve the purpose that determine whether to
commit or not?
by the way, the method MappedFile#isAbleToCommit has similar logic, the code:
int flush = this.committedPosition.get();
int write = this.wrotePosition.get();
...
if (commitLeastPages > 0) {
return ((write / OS_PAGE_SIZE) - (flush / OS_PAGE_SIZE)) >=
commitLeastPages;
}
I mean write / OS_PAGE_SIZE and commitLeastPages are the same dimensional
variables
Looking forward to your reply， thank you~
