2015-03-14Added support for offloading read() in thread pools.Valentin Bartenev1-0/+5
2015-02-11Refactored sendfile() AIO preload.Valentin Bartenev1-0/+1
This reduces layering violation and simplifies the logic of AIO preread, since it's now triggered by the send chain function itself without falling back to the copy filter. The context of AIO operation is now stored per file buffer, which makes it possible to properly handle cases when multiple buffers come from different locations, each with its own configuration.
2014-03-31Added #ifndef around NGX_HAVE_CASELESS_FILESYSTEM define.Maxim Dounin1-0/+2
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.
2013-09-23Added ngx_filename_cmp() with "/" sorted to the left.Maxim Dounin1-11/+0
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.
2013-09-02Disable symlinks: use O_PATH to open path components.Valentin Bartenev1-0/+3
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.
2013-07-05Make macros safe.Gleb Smirnoff1-5/+5
2012-03-27Fixed unconditional MAX_PATH usage (ticket #22).Maxim Dounin1-1/+12
POSIX doesn't require it to be defined, and Debian GNU/Hurd doesn't define it. Note that if there is no MAX_PATH defined we have to use realpath() with NULL argument and free() the result.
2012-02-28Workaround 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).
2012-02-21Disable symlinks: use O_SEARCH|O_DIRECTORY to open path components.Valentin Bartenev1-0/+17
2012-02-20Disable symlinks: added explicit cast of AT_FDCWD (ticket #111).Maxim Dounin1-0/+2
Solaris has AT_FDCWD defined to unsigned value, and comparison of a file descriptor with it causes warnings in modern versions of gcc. Explicitly cast AT_FDCWD to ngx_fd_t to resolve these warnings.

2011-11-14Introduction of simple ngx_write_stderr() instead of ngx_log_stderr()Igor Sysoev1-0/+1
for output of ./configure options, etc., since ngx_log_stderr() output length is limited by 2048 characters defined as NGX_MAX_ERROR_STR.

2011-04-22Use more precise stat.st_blocks to account cache size on UnixIgor Sysoev1-0/+1
instead of file length rounded to a file system block size. There is no similar way on Windows, so rounding to a cache->bsize is kept.
