Merge of r4500: fixed spelling in single-line comments.

Merge of r4499: workaround for fs_size on ZFS (ticket #46).

2012-03-05T13:20:40+00:00

ZFS reports incorrect st_blocks until file settles on disk, and this
may take a while (i.e. just after creation of a file the st_blocks value
is incorrect).  As a workaround we now use st_blocks only if
st_blocks * 512 > st_size, this should fix ZFS problems while still
preserving accuracy for other filesystems.

The problem had appeared in r3900 (1.0.1).

Merge of r4460: ngx_ncpu detection for most *nix platforms.

2012-03-05T12:10:09+00:00

This inaccurate detection by using sysconf(_SC_NPROCESSORS_ONLN) can improve
usage of the mutex lock optimization on multicore systems.

Fixed AIO error handling on FreeBSD.

The aio_return() must be called regardless of the error returned by
aio_error().  Not calling it resulted in various problems up to segmentation
faults (as AIO events are level-triggered and were reported again and again).

Additionally, in "aio sendfile" case r->blocked was incremented in case of
error returned from ngx_file_aio_read(), thus causing request hangs.

Merge of r4406, r4413: copyrights updated.

Merge of r4404:

2012-02-05T19:25:24+00:00

Fixed sched_setaffinity(2) to correctly pass size.

Second argument (cpusetsize) is size in bytes, not in bits.  Previously
used constant 32 resulted in reading of uninitialized memory and caused
EINVAL to be returned on some Linux kernels.

Microoptimization of sendfile(2) usage under FreeBSD.

FreeBSD kernel checks headers/trailers pointer against NULL, not
corresponding count.  Passing NULL if there are no headers/trailers
helps to avoid unneeded work in kernel, as well as unexpected 0 bytes
GIO in traces.

Introduction of simple ngx_write_stderr() instead of ngx_log_stderr()
for output of ./configure options, etc., since ngx_log_stderr() output
length is limited by 2048 characters defined as NGX_MAX_ERROR_STR.

Configure/build changes and fixes:

*) Revamped "configure --help" text.

*) FreeBSD 10-current has recently gotten POSIX_FADV_* macros.
   A fix for the broken build applied.

*) AIX 7 defines sys_nerr in errno.h, therefore  included
   in the sys_nerr test.

   When sys_nerr and _sys_nerr are missed on a particular platform
   and our euristic for a maximum errno detection applied always
   print the maximum errno number we reached instead of printing void.

   This makes possible to build nginx on AIX 7.1.

*) Made it possible to build/install from the SVN checkout.

Merge of r4227, r4228:

2011-12-14T13:06:45+00:00

Fixed range checking for the "somaxconn" sysctl.  Fixed port range checking.
