2012-03-05Merge of r4500: fixed spelling in single-line comments.Maxim Dounin4-4/+4
2012-03-05Merge of r4499: workaround for fs_size on ZFS (ticket #46).Maxim Dounin1-2/+3
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).
2012-03-05Merge of r4460: ngx_ncpu detection for most *nix platforms.Maxim Dounin1-0/+6
This inaccurate detection by using sysconf(_SC_NPROCESSORS_ONLN) can improve usage of the mutex lock optimization on multicore systems.
2012-02-05Merge of r4416:Maxim Dounin1-18/+9
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.

2012-02-05Merge of r4404:Maxim Dounin1-1/+4
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.
2012-02-05Merge r4336:Maxim Dounin1-2/+7
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.
2011-12-14Merge of r4284:Maxim Dounin2-0/+2
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 <errno.h> 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.
2011-12-14Merge of r4227, r4228:Maxim Dounin2-12/+5
Fixed range checking for the "somaxconn" sysctl. Fixed port range checking.
2011-12-13Merge of r4221, r4222:Maxim Dounin1-4/+14
Fixed unix ngx_write_chain_to_file() to return total bytes written. Previously result of last iteration's writev() was returned. This was unnoticed as return value was only used if chain contained only one or two buffers.

Windows related fixes: *) Fixed segmentation fault with empty config on Windows. See here for report: http://mailman.nginx.org/pipermail/nginx-ru/2011-September/043288.html *) Recent SDKs allow to build IPV6 only for Windows XP or above. *) Fixing conflict with SDK off_t definition. *) Fix of building by Microsoft Visual C++ 10 compiler.
2011-11-01Merging r4132, r4134, r4143, r4183, r4191, r4199:Igor Sysoev6-6/+7
Various fixes related to error messages: *) Removed old warning that suggested to use "server_name_in_redirect off" (now the default) in place of no longer supported "server_name *". *) Fixing directive name in error message if types hash size is not enough. *) Replaced "can not" with "cannot" and "could not" in a bunch of places. Fixed nearby grammar errors. *) Overhauled error messages.
2011-11-01Merging r4020:Igor Sysoev1-2/+7
SIGWINCH/NOACCEPT signal is disabled now in non-daemon mode. Non-daemon mode is currently used by supervisord, daemontools and so on or during debugging. The NOACCEPT signal is only used for online upgrade which is not supported when nginx is run under supervisord, etc., so this change should not break existant setups.
2011-11-01Merging r4017:Igor Sysoev2-10/+0
Move SO_ACCEPTFILTER and TCP_DEFER_ACCEPT checks into configure. NetBSD 5.0+ has SO_ACCEPTFILTER support merged from FreeBSD, and having accept filter check in FreeBSD-specific ngx_freebsd_config.h prevents it from being used on NetBSD. Therefore move the check into configure (and do the same for Linux-specific TCP_DEFER_ACCEPT, just to be in line).

Linux AIO related fixes: *) Fixing Linux AIO syscalls return value handling: syscall(2) uses usual libc convention, it returns -1 on error and sets errno. Obsolete _syscall(2) returns negative value of error. *) Fixing Linux AIO initiatialization: AIO operations are disabled if kernel does not support them. Previously worker just exited. *) The "worker_aio_requests" directive. The default value is 32 AIO simultaneous requests per worker. Previously they were hardcoded to 1024, and it was too large, since Linux allocated them early on io_setup(), but not on request itself. So with default value of /proc/sys/fs/aio-max-nr equal to 65536 only 64 worker processes could be run simultaneously. 32 AIO requests are enough for modern disks even if server runs only 1 worker.

In Mac OS X Lion, Apple deprecated the use of the system OpenSSL library in favour of their CommonCrypto library. This change adds a work-around that allows nginx to still be built on Lion with OpenSSL.
2011-09-30Merging r4077, r4101, r4102:Igor Sysoev2-0/+7
open_file_cache related fixes: *) Bugfix: open_file_cache lost is_directio flag. On file retest open_file_cache lost is_directio if file wasn't changed. This caused unaligned operations under Linux to fail with EINVAL. It wasn't noticeable with AIO though, as errors wasn't properly logged. *) Bugfix: open_file_cache did not update file info on retest. If file inode was not changed, cached file information was not updated on retest. As a result stale information might be cached forever if file attributes was changed and/or file was extended.

Cache loader improvements: The cache loader performs two tasks: inserting cache objects in inactivity list and evaluating total cache size. Reading just directory is enough for this purpose. Elimination of reading cache files saves at least one disk I/O operation per file.
