+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+
+See this thread for details:
+http://mailman.nginx.org/pipermail/nginx/2010-November/023693.html

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.

+See here for details:

+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+
+See this thread for details:
+http://mailman.nginx.org/pipermail/nginx/2010-November/023693.html

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.

+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.
+
+See here for details:

+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+
+See this thread for details:

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.
+
+See here for details:

+# Date 1315324342 -14400
+# Node ID 4cf0af103bc382a78f894302d1706929a79df4bb

+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+
+See this thread for details:
+http://mailman.nginx.org/pipermail/nginx/2010-November/023693.html

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.
+
+See here for details:

++This is an Nginx fork that adds dtrace USDT probes.
+ 
+-Documentation is available at http://nginx.org
++This is still under development and not usable yet.
++
++Installation:
++
++    ./configure --with-dtrace-probes \
++        --with-dtrace=/usr/sbin/dtrace \
++        ...
++    make
++    make install
++
++Usage on Linux (with systemtap):
++
++    # make the stap-nginx script visiable in your PATH
++    export PATH=/usr/local/nginx/sbin:$PATH
++
++    # list all the static probes available in your nginx
++    stap-nginx -L 'process("nginx").mark("*")'
++
++    # run the test.stp file
++    stap-nginx test.stp
++
++Sample test.stp file:
++
++    probe begin
++    {
++        print("Tracing.  Hit CTRL-C to stop.\n")
++    }
++
++    probe process("nginx").mark("http-subrequest-start")
++    {
++        printf("uri: %s?%s\n", ngx_http_req_uri($arg1),
++            ngx_http_req_args($arg1))
++    }
++
++For now, only tested on Solaris 11 Express and Fedora Linux 17.
++
++The original Nginx documentation is available at http://nginx.org
