This reduces the number of moving parts in ABI compatibility checks.
Additionally, it also allows to use OpenSSL in FIPS mode while still
using md5 for non-security tasks.
This parameter lets binding the proxy connection to a non-local address.
Upstream will see the connection as coming from that address.
When used with $remote_addr, upstream will accept the connection from real
client address.
Example:
proxy_bind $remote_addr transparent;
Added (RTLD_NOW | RTLD_GLOBAL) to dlopen() test. There is no RTLD_GLOBAL
on FreeBSD 2.2.9.
Added uint32_t test, with fallback to u_int32_t, similar to uint64_t one.
Added fallback to u_int32_t in in_addr_t test.
With these changes it is now possible to compile nginx on FreeBSD 2.2.9
with only few minor warnings (assuming -Wno-error).
Fixed a regression introduced in rev. 434548349838 that prevented
auto/types/sizeof and auto/types/typedef properly reporting autotest
source code to autoconf.err in case of test failure.
OPENSSL_config() deprecated in OpenSSL 1.1.0. Additionally,
SSL_library_init(), SSL_load_error_strings() and OpenSSL_add_all_algorithms()
are no longer available if OPENSSL_API_COMPAT is set to 0x10100000L.
The OPENSSL_init_ssl() function is now used instead with appropriate
arguments to trigger the same behaviour. The configure test changed to
use SSL_CTX_set_options().
Deinitialization now happens automatically in OPENSSL_cleanup() called
via atexit(3), so we no longer call EVP_cleanup() and ENGINE_cleanup()
directly.
Just using "cp" is incorrect, as it will overwrite old files
possibly used by OS, leading to unexpected effects. Changed
to "mv + cp", much like used for the main binary.
The "build" target introduced to do all build-related tasks, and
it is now used in Makefile and in objs/Makefile as a dependency for
the "install" target.
In particular, this resolves problems as observed with dynamic modules
by people trying to do "make install" without calling "make" first.
The install_sw target first appeared in OpenSSL 0.9.7e and is documented since
OpenSSL 1.0.0 as the way to install the OpenSSL software without documentation.
Before 7142b04337d6, it was possible to build the OpenSSL library
along with nginx, and link nginx statically with this library
(--with-openssl=DIR --with-ld-opt=-static --with-http_ssl_module).
This was broken on Linux by not adding -ldl after -lcrypto.
The fix also makes it possible to link nginx statically on Linux
with the system OpenSSL library, which never worked before.
Now we always set NGX_CC_NAME to "msvc", and additionally test compiler
version as reported by "cl" in auto/cc/msvc (the same version is also
available via the _MSC_VER define). In particular, this approach allows
to properly check for C99 variadic macros support, which previously was
not used with MSVC versions not explicitly recognized.
Now unneeded wildcards in NGX_CC_NAME tests for msvc removed accordingly,
as well as unused wildcards for owc and icc.
The auto/module script is extended to understand ngx_module_link=DYNAMIC.
When set, it links the module as a shared object rather than statically
into nginx binary. The module can later be loaded using the "load_module"
directive.
New auto/module parameter ngx_module_order allows to define module loading
order in complex cases. By default the order is set based on ngx_module_type.
3rd party modules can be compiled dynamically using the --add-dynamic-module
configure option, which will preset ngx_module_link to "DYNAMIC" before
calling the module config script.
Win32 support is rudimentary, and only works when using MinGW gcc (which
is able to handle exports/imports automatically).
In collaboration with Ruslan Ermilov.
This script simplifies configuration of additional modules,
including 3rd party ones. The script is extensible, and
will be used to introduce dynamic linking of modules in upcoming
changes.
3rd party module config scripts are called with ngx_module_link
preset to "ADDON" - this allows config scripts to call auto/module
without ngx_module_link explicitly defined, as well as testing if
new interface is in place if compatibility with older nginx versions
is desired.
In collaboration with Ruslan Ermilov.
Additionally, HTTP_HEADERS_FILTER_MODULE now added to HTTP_FILTER_MODULES.
This avoids explict use of modules at the later stages, now only module
lists are used. This will be needed in later patches.
Splits a request into subrequests, each providing a specific range of response.
The variable "$slice_range" must be used to set subrequest range and proper
cache key. The directive "slice" sets slice size.
The following example splits requests into 1-megabyte cacheable subrequests.
server {
listen 8000;
location / {
slice 1m;
proxy_cache cache;
proxy_cache_key $uri$is_args$args$slice_range;
proxy_set_header Range $slice_range;
proxy_cache_valid 200 206 1h;
proxy_pass http://127.0.0.1:9000;
}
}
The function is now called ngx_parse_http_time(), and can be used by
any code to parse HTTP-style date and time. In particular, it will be
used for OCSP stapling.
For compatibility, a macro to map ngx_http_parse_time() to the new name
provided for a while.
