This commit the following variables to construct request line without
including query component:
* $method
* $path
* $path_without_query
* $protocol_version
With --ocsp-startup option, nghttpx starts accepting connections after
initial attempts to get OCSP responses finish. It does not matter
some of the attempts fail. This feature is useful if OCSP responses
must be available before accepting connections.
This commit adds 2 new options to handle X-Forwarded-Proto header
field. The --no-add-x-forwarded-proto option makes nghttpx not to
append X-Forwarded-Proto value. The
--no-strip-incoming-x-forwarded-proto option prevents nghttpx from
stripping the header field from client.
Previously, nghttpx always strips incoming header field, and set its
own header field. This commit preserves this behaviour, and adds
additional knobs.
With --single-process option, nghttpx will run in a single process
mode where master and worker are unified into one process. nghttpx
still spawns additional process for neverbleed. In the single process
mode, signal handling is disabled.
This commit adds 2 new options to handle X-Forwarded-Proto header
field. The --add-x-forwarded-proto option makes nghttpx append
X-Forwarded-Proto value. The --strip-incoming-x-forwarded-proto
option makes nghttpx to strip the header field from client.
Previously, nghttpx always strips incoming header field, and set its
own header field. This commit changes this behaviour. Now nghttpx
does not strip, and append X-Forwarded-Proto header field by default.
The X-Forwarded-For, and Forwarded header fields are also handled in
the same way. To recover the old behaviour, use
--add-x-forwarded-proto and --strip-incoming-x-forwarded-proto
options.
Previously, nghttpx will use only one single thread inside the worker
process if --workers=1 (this is default). If --workers=N, N > 1, we
use additional threads for accepting connections, or API request
processing, etc.
With this commit, we use the same processing model for N > 1 even if N
== 1. To restore the original single thread execution mode,
--single-worker option is added. If threading is disabled
--single-worker is always true.
This commit removes frontend-tls parameter, and adds
redirect-if-not-tls parameter parameter to --backend option. nghttpx
now responds to the request with 308 status code to redirect the
request to https URI if frontend connection is not TLS encrypted, and
redirect-if-no-tls parameter is used in --backend option. The port
number in Location header field is 443 by default (thus omitted), but
it can be configurable using --redirect-https-port option.
This commit deprecates --tls-proto-list option, and adds 2 new
options: --tls-min-proto-version and --tls-max-proto-version to
specify minimum and maximum protocol version respectively. Versions
between the two are enabled. The deprecated --tls-proto-list has
empty default value, and acts like enabling only specific protocol
versions in the range for now.
--accesslog-write-early option is analogous to HAProxy's logasap. If
used, nghttpx writes access log when response header fields are
received from backend rather than when request transaction finishes.
Previously, ciphers option sets cipher list for both frontend and
backend TLS connections. With this commit, ciphers option only sets
cipher list for frontend connections. The new client-ciphers option
sets cipher list for backend connection.
This commit adds client-no-http2-cipher-black-list option to disable
enforcement of HTTP/2 cipher black list on backend HTTP/2 connection.
Previously, existing no-http2-cipher-black-list option disables it for
both frontend and backend connections. Now no-http2-cipher-black-list
option only disables it for frontend connection.
This option requires OpenSSL >= 1.0.2. With OpenSSL 1.0.2, the
default value is "P-256". With OpenSSL 1.1.0 or later, the default
value is "X25519:P-256".
We added --frontend-http2-window-size,
--frontend-http2-connection-window-size, --backend-http2-window-size,
and --backend-http2-connection-window-size option to replace existing
*-bits options. The old options are not flexible because they only
specify number of bits. Now we can specify integer value, with
possible g, m, and k unit. The old options are still available for
backend compatibility, but are deprecated.
