New Revision: 5108
URL: http://trac.nginx.org/nginx/changeset/5108/nginx
Log:
Gzip: fixed setting of NGX_HTTP_GZIP_BUFFERED.
In r2411 setting of NGX_HTTP_GZIP_BUFFERED in c->buffered was moved from
ngx_http_gzip_filter_deflate_start() to ngx_http_gzip_filter_buffer() since
it was always called first. But in r2543 the "postpone_gzipping" directive
was introduced, and if postponed gzipping is disabled (the default setting),
ngx_http_gzip_filter_buffer() is not called at all.
We must always set NGX_HTTP_GZIP_BUFFERED after the start of compression
since there is always a trailer that is buffered.
There are no known cases when it leads to any problem with current code.
But we already had troubles in upcoming SPDY implementation.
