This was missed in 9d59a8eda373 when non-buffered support was added to SCGI
and uwsgi.

Casts between pointers and integers produce warnings on size mismatch. To
silence them, cast to (u)intptr_t should be used. Prevoiusly, casts to
ngx_(u)int_t were used in some cases, and several ngx_int_t expressions had
no casts.
As of now it's mostly style as ngx_int_t is defined as intptr_t.
|
|
On win32, time_t is 64 bits wide by default, and passing an ngx_msec_int_t
argument for %T format specifier doesn't work. This doesn't manifest itself
on other platforms as time_t and ngx_msec_int_t are usually of the same size.
|

Several false positive warnings silenced, notably W8012 "Comparing
signed and unsigned" (due to u_short values promoted to int), and
W8072 "Suspicious pointer arithmetic" (due to large type values added
to pointers).
With this patch, it's now again possible to compile nginx using bcc32,
with options we normally compile on win32 minus ipv6 and ssl.
|
|
Precompiled headers are disabled as they lead to internal compiler errors
with long configure lines. Couple of false positive warnings silenced.
Various win32 typedefs are adjusted to work with Open Watcom C 1.9 headers.
With this patch, it's now again possible to compile nginx using owc386,
with options we normally compile on win32 minus ipv6 and ssl.

Because of premature check the effective buffer size was 255 symbols
while the buffer is able to handle 256.
|

This allows to approach "server_name" values specified below the
"valid_referers" directive when used within the "server_names" parameter, e.g.:
server_name example.org;
valid_referers server_names;
server_name example.com;
As a bonus, this fixes bogus error with "server_names" specified several times.
|
|
The server_name regexes are normally compiled for case-sensitive matching.
This violates case-insensitive obligations in the referer module. To fix
this, the host string is converted to lower case before matching.
Previously server_name regex was executed against the whole referer string
after dropping the scheme part. This could led to an improper matching, e.g.:
server_name ~^localhost$;
valid_referers server_names;
Referer: http://localhost/index.html
It was changed to look only at the hostname part.
The server_name regexes are separated into another array to not clash with
regular regexes.

If Content-Length header is not set, and the image size is larger than the
buffer size, client will hang until a timeout occurs.
Now NGX_HTTP_UNSUPPORTED_MEDIA_TYPE is returned immediately.

This allows to build a directory listing whenever a loop exists in symbolic
link resolution of the path argument.

This prevents ngx_http_finalize_request() from issuing
ngx_http_special_response_handler() on a freed context.
|
|
While ngx_get_full_name() might have a bit more descriptive arguments,
the ngx_conf_full_name() is generally easier to use when parsing
configuration and limits exposure of cycle->prefix / cycle->conf_prefix
details.

|
When matching a compiled regex against value in the "Referer" header field,
the length was calculated incorrectly for strings that start from "https://".
This might cause matching to fail for regexes with end-of-line anchors.
Patch by Liangbin Li.

|
The ngx_get_full_name() function takes more readable arguments list.

As it is defined by RFC 4627, and allows for various browser tools like
JSONView to display JSON well-formatted.

Though there are several MIME types commonly used for JavaScript nowadays,
the most common being "text/javascript", "application/javascript", and
currently used by nginx "application/x-javascript", RFC 4329 prefers
"application/javascript".
The "charset_types" directive's default value was adjusted accordingly.
|
|
As per perlxs, C preprocessor directives should be at the first
non-whitespace of a line to avoid interpreting them as comments.
#if and #endif are moved so that there are no blank lines before them
to retain them as part of the function body.
|
|
Checks were added to both buffered and unbuffered code paths to detect
and complain if a response is incomplete. Appropriate error codes are
now passed to ngx_http_upstream_finalize_request().
With this change in unbuffered mode we now use u->length set to -1 as an
indicator that EOF is allowed per protocol and used to indicate response
end (much like its with p->length in buffered mode). Proxy module was
changed to set u->length to 1 (instead of previously used -1) in case of
chunked transfer encoding used to comply with the above.
|
|
That is, by default we assume that response end is signalled by
a connection close. This seems to be better default, and in line
with u->pipe->length behaviour.
Memcached module was modified accordingly.
|
|
This allows to finalize unfinished responses while still sending as
much data as available.
|
|
After a failed partial match we now check if there is another partial
match in previously matched substring to fix cases like "aab" in "aaab".
The ctx->saved string is now always sent if it's present on return
from the ngx_http_sub_parse() function (and reset accordingly). This
allows to release parts of previously matched data.
|
|
If a pattern was partially matched at a response end, partially matched
string wasn't send. E.g., a response "fo" was truncated to an empty response
if partially mathed by a pattern "foo".

The exsltRegisterAll() needs to be called before XSLT stylesheets
are compiled, else stylesheet compilation hooks will not work. This
change fixes EXSLT Functions extension.

On Linux, sockaddr length is required to process unix socket addresses properly
due to unnamed sockets (which don't have sun_path set at all) and abstract
namespace sockets.
|
|
It was broken by X-Forwarded-For related changes in f7fe817c92a2 (1.3.14)
as hh->offset is no longer 0 for Cookie.

The module always produces only one and obviously the last buffer in chain.

The parameter is mostly identical to http_404, and is expected to
be used in similar situations. The 403 code might be returned by
a backend instead of 404 on initial sync of new directories with rsync.

Directive is similar to ssi_last_modified and sub_filter_last_modified

Patch by Alexey Kolpakov.

The "ssi_last_modified" directive allows to preserve Last-Modified header
in SSI responses. The directive is similar to SSILastModified one available
in Apache:

An invalid memcached reply that started with '\n' could cause
segmentation fault.
An invalid memcached reply "VALUE / 0 2\r?ok\r\nEND\r\n" was
considered as a valid response.
In addition, if memcached reports that the key was not found,
set u->headers_in.content_length_n to 0. This ensures that
ngx_http_memcached_filter() will not be called while previous
code relied on always intercepting 404. Initialization of
ctx->rest was moved to where it belongs.
|
|
This makes it accessible via dynamic lookup with ngx_http_get_variable()
from Perl, SSI, etc.

Due to peer->checked always set since rev. c90801720a0c (1.3.0)
by round-robin and least_conn balancers (ip_hash not affected),
the code in ngx_http_upstream_free_round_robin_peer() function
incorrectly reset peer->fails too often.

The provided argument list didn't follow a used format string.

Previous code is believed to be safe, but might access uninitialized
memory (e.g., e->quote).
|
|
The $proxy_internal_body_length value might change during request lifetime,
notably if proxy_set_body used, and use of a cached value might result in
incorrect upstream requests.
