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