annotate src/os/unix/ngx_gcc_atomic_sparc64.h @ 579:be4f34123024 NGINX_0_8_35
nginx 0.8.35
*) Change: now the charset filter runs before the SSI filter.
*) Feature: the "chunked_transfer_encoding" directive.
*) Bugfix: an "&" character was not escaped when it was copied in
arguments part in a rewrite rule.
*) Bugfix: nginx might be terminated abnormally while a signal
processing or if the directive "timer_resolution" was used on
platforms which do not support kqueue or eventport notification
methods.
Thanks to George Xie and Maxim Dounin.
*) Bugfix: if temporary files and permanent storage area resided at
different file systems, then permanent file modification times were
incorrect.
Thanks to Maxim Dounin.
*) Bugfix: ngx_http_memcached_module might issue the error message
"memcached sent invalid trailer".
Thanks to Maxim Dounin.
*) Bugfix: nginx could not built zlib-1.2.4 library using the library
sources.
Thanks to Maxim Dounin.
*) Bugfix: a segmentation fault occurred in a worker process, if there
was large stderr output before FastCGI response; the bug had
appeared in 0.8.34.
Thanks to Maxim Dounin.

10 * | |
11 * if ([r1] == r2) { | |

13 * } else { | |
14 * r0 = [r1]; | |
