nginx.git/src/os/unix, branch release-1.5.13

Added #ifndef around NGX_HAVE_CASELESS_FILESYSTEM define.

2014-03-31T17:38:25+00:00

This brings Cygwin compilation in line with other case-insensitive
systems (notably win32 and OS X) where one can force case sensitivity
using -DNGX_HAVE_CASELESS_FILESYSTEM=0.

Added connection serial number in logging of left open sockets.

2014-03-06T19:15:10+00:00

Use ngx_socket_errno where appropriate.

Core: handle getsockopt(TCP_FASTOPEN) failures.

2014-01-30T22:58:21+00:00

Linux returns EOPNOTSUPP for non-TCP sockets and ENOPROTOOPT for TCP
sockets, because getsockopt(TCP_FASTOPEN) is not implemented so far.

While there, lower the log level from ALERT to NOTICE to match other
getsockopt() failures.

Added per-process random seeding (ticket #456).

Core: handling of getsockopt(TCP_DEFER_ACCEPT) failures.

2013-10-31T00:00:37+00:00

Recent Linux versions started to return EOPNOTSUPP to getsockopt() calls
on unix sockets, resulting in log pollution on binary upgrade.  Such errors
are silently ignored now.

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.

Fixed handling of the ready flag with kqueue.

2013-09-05T12:53:02+00:00

There is nothing to do more when recv() has returned 0,
so we should drop the flag.

Disable symlinks: use O_PATH to open path components.

2013-09-02T04:07:59+00:00

It was introduced in Linux 2.6.39, glibc 2.14 and allows to obtain
file descriptors without actually opening files.  Thus made it possible
to traverse path with openat() syscalls without the need to have read
permissions for path components.  It is effectively emulates O_SEARCH
which is missing on Linux.

O_PATH is used in combination with O_RDONLY.  The last one is ignored
if O_PATH is used, but it allows nginx to not fail when it was built on
modern system (i.e. glibc 2.14+) and run with a kernel older than 2.6.39.
Then O_PATH is unknown to the kernel and ignored, while O_RDONLY is used.

Sadly, fstat() is not working with O_PATH descriptors till Linux 3.6.
As a workaround we fallback to fstatat() with the AT_EMPTY_PATH flag
that was introduced at the same time as O_PATH.

Added the NGX_EBADF define.
