Fixed failure to start cache manager and cache loader processes
if there were more than 512 listening sockets in configuration.
|
|
Worker processes are now made aware of their sequential number needed
to select CPU affinity mask. This replaces a workaround from r4865.
|
|
*) Made sure to initialize the entire ngx_file_t structure.
Found by Coverity.
*) Correct plural form for "path" in the whole source base.
*) Removed conditional compilation from waitpid() error test.
There are reports that call to a signal handler for an exited process
despite waitpid() already called for the process may happen on Linux
as well.
*) Style, parentheses instead of braces in misc/GNUMakefile.

This fixes unwanted/incorrect cpu_affinity use on dead worker processes
respawn. While this is not ideal, it's expected to be better when previous
situation where multiple processes were spawn with identical CPU affinity
set.
Reported by Charles Chen.

*) Resolver: fixed format specification.
Patch by Yichun Zhang (agentzh).
*) Support for IPv6 literals and an optional port in resolver.
*) Fixed crash in ngx_resolver_cleanup_tree().
If sending a DNS request fails with an error (e.g., when mistakenly
trying to send it to a local IP broadcast), such a request is not
deleted if there are clients waiting on it. However, it was still
erroneously removed from the queue. Later ngx_resolver_cleanup_tree()
attempted to remove it from the queue again that resulted in a NULL
pointer dereference.
*) When "resolver" is configured with a domain name, only the first
resolved address was used. Now all addresses will be used.
*) Fixed segfault with poll and resolver used.
Poll event method needs ngx_cycle->files to work, and use of
ngx_exit_cycle without files set caused null pointer dereference in
resolver's cleanup on udp socket close.

This is expected to ensure smoother operation on reload (and with less
chance of listen queue overflows).
Prodded by Igor Sysoev.

Second argument (cpusetsize) is size in bytes, not in bits. Previously
used constant 32 resulted in reading of uninitialized memory and caused
EINVAL to be returned on some Linux kernels.

Fixed nearby grammar errors.

*) change ngx_time_update() interface since there are no notification methods

message from a channel, the process tries to read the channel again.
The kernel (at least FreeBSD) may preempt the process and sends a SIGIO
signal to a master process. The master process sends a new terminate message,
the kernel switches again to the the child process, and the child process
reads the messages instead of an EAGAIN error. And this may repeat over
and over. Being that the child process can not exit the cycle and test
the termination flag set by the message handler.
The fix disallow the master process to send a new terminate message on
SIGIO signal reception. It may send the message only on SIGALARM signal.

*) Feature: the ngx_http_map_module.
*) Feature: the "types_hash_max_size" and "types_hash_bucket_size"
directives.
*) Feature: the "ssi_value_length" directive.
*) Feature: the "worker_rlimit_core" directive.
*) Workaround: the connection number in logs was always 1 if nginx was
built by the icc 8.1 or 9.0 compilers with optimization for
Pentium 4.
*) Bugfix: the "config timefmt" SSI command set incorrect time format.
*) Bugfix: nginx did not close connection to IMAP/POP3 backend for the
SSL connections; the bug had appeared in 0.3.13.
Thanks to Rob Mueller.
*) Bugfix: segmentation fault may occurred in at SSL shutdown; the bug
had appeared in 0.3.13.
|
|
*) Feature: the new 444 code of the "return" directive to close
connection.
*) Feature: the "so_keepalive" directive in IMAP/POP3 proxy.
*) Bugfix: if there are unclosed connection nginx now calls abort()
only on gracefull quit and active "debug_points" directive.
|
|
*) Change: the "valid_referers" directive and the "$invalid_referer"
variable were moved to the new ngx_http_referer_module from the
ngx_http_rewrite_module.
*) Change: the "$apache_bytes_sent" variable name was changed to
"$body_bytes_sent".
*) Feature: the "$sent_http_..." variables.
*) Feature: the "if" directive supports the "=" and "!=" operations.
*) Feature: the "proxy_pass" directive supports the HTTPS protocol.
*) Feature: the "proxy_set_body" directive.
*) Feature: the "post_action" directive.
*) Feature: the ngx_http_empty_gif_module.
*) Feature: the "worker_cpu_affinity" directive for Linux.
*) Bugfix: the "rewrite" directive did not unescape URI part in
redirect, now it is unescaped except the %00-%25 and %7F-%FF
characters.
*) Bugfix: nginx could not be built by the icc 9.0 compiler.
*) Bugfix: if the SSI was enabled for zero size static file, then the
chunked response was encoded incorrectly.
