Nicolas Carrier <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Nicolas Carrier <[email protected]> --- Created attachment 36417 --> https://bz.apache.org/bugzilla/attachment.cgi?id=36417&action=edit Avoids pid file creation race condition by using a temporary file. The original pattern for creating the pid file was: open_create(pid_file) write(pid_file, pid) close(pid_file) But if a power outage occurs between open_create and write, the file will be empty and httpd will refuse to start afterwards unless the corrupt pid file is removed. This patch uses the pattern: open_create(temp_pid_file) write(temp_pid_file) close(temp_pid_file) rename(temp_pid_file, pid_file) which is guaranteed to be atomic, provided that temp_pid_file and pid_file are located in the same file system, which this patch does by creating a temporary file name with the pattern: pid_file_name + random_suffix -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
