23 * FileHandlerFactory is a LogHandlerFactory that constructs log handlers
24 * that write to a file.
26 * Note that FileHandlerFactory allows opening and appending to arbitrary files
27 * based on the handler options. This may make it unsafe to use
28 * FileHandlerFactory in some contexts: for instance, a setuid binary should
29 * generally avoid registering the FileHandlerFactory if they allow log
30 * handlers to be configured via command line parameters, since otherwise this
31 * may allow non-root users to append to files that they otherwise would not
32 * have write permissions for.
