nginx.git/src/core/ngx_string.h, branch release-1.29.1

Removed casts from ngx_memcmp() macro.

2022-11-30T15:01:53+00:00

Casts are believed to be not needed, since memcmp() has "const void *"
arguments since introduction of the "void" type in C89.  And on pre-C89
platforms nginx is unlikely to compile without warnings anyway, as there
are no casts in memcpy() and memmove() calls.

These casts were added in 1648:89a47f19b9ec without any details on why they
were added, and Igor does not remember details either.  The most plausible
explanation is that they were copied from ngx_strcmp() and were not really
needed even at that time.

Fixed alignment of ngx_memmove()/ngx_movemem() macro definitions.

Core: ngx_explicit_memzero().

Fixed handling of non-null-terminated unix sockets.

2017-10-04T18:19:38+00:00

At least FreeBSD, macOS, NetBSD, and OpenBSD can return unix sockets
with non-null-terminated sun_path.  Additionally, the address may become
non-null-terminated if it does not fit into the buffer provided and was
truncated (may happen on macOS, NetBSD, and Solaris, which allow unix socket
addresess larger than struct sockaddr_un).  As such, ngx_sock_ntop() might
overread the sockaddr provided, as it used "%s" format and thus assumed
null-terminated string.

To fix this, the ngx_strnlen() function was introduced, and it is now used
to calculate correct length of sun_path.

Autoindex: implemented JSON output format.

2014-12-12T17:25:35+00:00

Core: added ngx_encode_base64url().

2014-02-04T00:59:21+00:00

Added ngx_filename_cmp() with "/" sorted to the left.

2013-09-23T15:37:13+00:00

This patch fixes incorrect handling of auto redirect in configurations
like:

    location /0  { }
    location /a- { }
    location /a/ { proxy_pass ... }

With previously used sorting, this resulted in the following locations
tree (as "-" is less than "/"):

        "/a-"
    "/0"    "/a/"

and a request to "/a" didn't match "/a/" with auto_redirect, as it
didn't traverse relevant tree node during lookup (it tested "/a-",
then "/0", and then falled back to null location).

To preserve locale use for non-ASCII characters on case-insensetive
systems, libc's tolower() used.

Added "const" to ngx_memcpy() with NGX_MEMCPY_LIMIT defined.

2012-08-03T09:07:30+00:00

This fixes warning produced during compilation of the ngx_http_geoip_module
due to const qualifier being discarded.

Copyright updated.

Autoindex: escape '?' in file names.

2011-10-11T17:56:51+00:00

For files with '?' in their names autoindex generated links with '?' not
escaped.  This resulted in effectively truncated links as '?' indicates
query string start.

This is an updated version of the patch originally posted at [1].  It
introduces generic NGX_ESCAPE_URI_COMPONENT which escapes everything but
unreserved characters as per RFC 3986.  This approach also renders unneeded
special colon processing (as colon is percent-encoded now), it's dropped
accordingly.
