Each line in a file stored in the Common Log Format has the following syntax: host ident authuser date request status bytes The format is extended by the Combined Log Format with referer and user-agent ...
In computing, timestamping refers to the use of an electronic timestamp to provide a temporal order among a set of events. Timestamping techniques are used in a variety of computing fields, from network management and computer security to concurrency control .
Practically all computer file systems store one or more timestamps in the per-file metadata. In particular, most modern operating systems support the POSIX stat (system call) , so each file has three timestamps associated with it: time of last access (atime: ls -lu ), time of last modification (mtime: ls -l ), and time of last status change ...
In this case, if the transaction's timestamp is after the object's read timestamp, the read timestamp is set to the transaction's timestamp. If a transaction wants to write to an object, but the transaction started before the object's read timestamp it means that something has had a look at the object, and we assume it took a copy of the object ...
