update license header text
Revert r395231 from the 2.2.x branch. This gets us back to the old place with regard to the copyright statements.
Update the last year of copyright for the 2.2.x branch
No functional change: remove trailing whitespace. This also means that "blank" lines, which had consisted of just spaces and/or tabs are now truly blank lines
Recreate 2.2.x branch from trunk.
Update copyright year to 2005 and standardize on current copyright owner line.
general property cleanup
fix name of The Apache Software Foundation
fix copyright dates according to the first checkin
apply Apache License, Version 2.0
update license to 2004.
switch to APR 1.0 API (which is still in flux) because of the changes to the argument lists of apr_mmap_dup and apr_socket_create, 2.1-dev won't build with apr and apr-util's 0.9 branch anymore
Minor cleanup: * pod.c (pod_signal_internal): apr_file_write() is defined to never return EINTR, so don't check for that case.
SECURITY: Eliminated leaks of several file descriptors to child processes, such as CGI scripts. PR: 17206 Submitted by: Christian Kratzer <ck@cksoft.de>, Bjoern A. Zeeb <bz@zabbadoz.net> Reviewed by: Joe Orton, Will Rowe
finished that boring job: update license to 2003. Happy New Year! ;-))
Remove many unnecessary includes, incl. apr_lock.h
worker MPM: get MaxRequestsPerChild to work again by allowing the main thread of a child to be interrupted by one of the other threads in the process this should get graceful termination to work after encountering one of the various possible error conditions in the listener and worker threads
Make the listener thread stop accepting new connections and exit cleanly at graceful restart time. This is a basic requirement of reliable graceful restarts (the kind that won't drop connections). This allows a future fix to make worker threads hang around until they service all connections previously accepted by the listener thread. The old mechanism of doing a dummy connection to wake up the listener thread in each old child process didn't work. It didn't guarantee that (in the main thread) the byte was read from the pod and global variables were set before the listener thread grabbed the connection. It didn't guarantee that a child process in the new generation didn't get some of the dummy connections. Rather than burn extra syscalls adding a unique socket or pipe to the poll set (and breaking single listen unserialized accept in the same change), this uses a signal sent from the main thread to the listener thread to break it out of the poll or accept. (We don't worry about breaking it out of the optional mutex because the child process holding the mutex will break out of poll/accept and release the mutex, allowing a child blocked in the mutex to get it. Eventually all children blocked in the mutex will come out.) Since the listener thread now exits reliably, the main thread joins it. PR: Obtained from: Submitted by: Reviewed by:
Update our copyright for this year.
close a nearly-impossible leak in dummy_connection (the copy of the code used by worker MPM)
Remove all signal handling from the worker MPM's child processes. Instead, we use the pipe of death for all communication between parent and child.
