IPv6 related fixes:
*) fix IPv6 listen socket handling while reconfiguring
*) test wildcard tail hash existance for IPv6 addresses,
the same fix for IPv4 addresses has been made in r2581
*) always run regex in server_name to get captures for IPv6 addresses,
the same fix for IPv4 addresses has been made in r2584
*) MSVC8 compatibility with OpenSSL 1.0.0
*) fix building OpenSSL-1.0.0 on 64-bit Linux:
make installs the libraries in lib64 directory
and build nginx/Windows against OpenSSL-0.9.8n
signal processing stability:
*) use sys_errlist[] in signal handler instead
of non Async-Signal-Safe strerror_r()
*) do not update time in the timer signal handler,
since localtime_r() is not Async-Signal-Safe function
*) use previously cached GMT offset value to update time from a signal handler
*) change ngx_time_update() interface since there are no notification methods
those return time
*) introduce ngx_time_sigsafe_update() to update the error log time only
*) change ngx_time_update() interface
*) make $request_method non-cacheable
*) make $arg_ variables non-cacheable
*) change processing variables accessed by SSI and perl module:
*) the indexed variables are always flushed
*) never show warning for not found variables
SSL fixes:
*) decrease SSL handshake error level to info
*) Set SSL session context for "ssl_session_cache none".
This fixes a bug when client certficate is used and nginx closes connection
with the message: "SSL_GET_PREV_SESSION:session id context uninitialized".
*) add OpenSSL_add_all_algorithms(), this fixes the error
"ASN1_item_verify:unknown message digest algorithm" occurred if
client certificate is signed using sha256WithRSAEncryption
SSI fixes:
*) use content type of the parent request in SSI stub block output
instead of default one
*) SSI %s timefmt has no timezone offset
*) change ngx_http_ssi_filter and ngx_http_charset_filter order
*) do not store an encoded variable value as a new cached variable value
*) fix SSI include stub for valid empty responses
*) allow to use $uid_got in SSI and perl module
fix miscellaneous name bugs:
*) fix $upstream_http_ variable prefix length
*) use a right "Location" header name, however, it did not harm,
since ngx_http_variable_sent_location() never use key name field
*) fix proxy_redirect name in error message
*) "proxy_redirect default" may not be used if a proxy_pass uses variables
browsers related fixes:
*) add MSIE padding for Chrome too
*) disable keepalive for Safari:
https://bugs.webkit.org/show_bug.cgi?id=5760
*) do not disable keepalive after POST requests for MSIE 7+
