Nginx and libatomic

by pcdinh

Hi, I tried to configure nginx 0.8.29 with libatomic 1.2 (manually built and installed) by specifying --with-libatomic=/usr/local/lib (=> /usr/local/lib/libatomic_ops.a) OR --with-libatomic=../libatomic_ops-1.2 (=> source code only) but nginx shows no information to indicate if that configuration works or not -------------------------------- checking for OS + Linux 2.6.18-164.el5PAE i686 checking for C compiler ... found + using GNU C compiler + gcc version: 4.1.2 20080704 (Red Hat 4.1.2-46) checking for gcc -pipe switch ... found checking for gcc builtin atomic operations ... not found checking for gcc variadic macros ... found checking for C99 variadic macros ... found checking for unistd.h ... found checking for inttypes.h ... found checking for limits.h ... found checking for sys/filio.h ... not found checking for sys/param.h ... found checking for sys/mount.h ... found checking for sys/statvfs.h ... found checking for crypt.h ... found checking for Linux specific features checking for epoll ... found checking for sendfile() ... found checking for sendfile64() ... found checking for sys/prctl.h ... found checking for prctl(PR_SET_DUMPABLE) ... found checking for sched_setaffinity() ... found checking for crypt_r() ... found checking for sys/vfs.h ... found checking for poll() ... found checking for /dev/poll ... not found checking for kqueue ... not found checking for crypt() ... not found checking for crypt() in libcrypt ... found checking for F_READAHEAD ... not found checking for posix_fadvise() ... found checking for O_DIRECT ... found checking for F_NOCACHE ... not found checking for directio() ... not found checking for statfs() ... found checking for statvfs() ... found checking for dlopen() ... not found checking for dlopen() in libdl ... found checking for sched_yield() ... found checking for OpenSSL library ... found checking for zlib library ... found checking for perl + perl version: v5.8.8 built for i386-linux-thread-multi + perl interpreter multiplicity found creating objs/Makefile checking for int size ... 4 bytes checking for long size ... 4 bytes checking for long long size ... 8 bytes checking for void * size ... 4 bytes checking for uint64_t ... found checking for sig_atomic_t ... found checking for sig_atomic_t size ... 4 bytes checking for socklen_t ... found checking for in_addr_t ... found checking for in_port_t ... found checking for rlim_t ... found checking for uintptr_t ... uintptr_t found checking for system endianess ... little endianess checking for size_t size ... 4 bytes checking for off_t size ... 8 bytes checking for time_t size ... 4 bytes checking for setproctitle() ... not found checking for pread() ... found checking for pwrite() ... found checking for strerror_r() ... found but is not working checking for gnu style strerror_r() ... found checking for localtime_r() ... found checking for posix_memalign() ... found checking for memalign() ... found checking for mmap(MAP_ANON|MAP_SHARED) ... found checking for mmap("/dev/zero", MAP_SHARED) ... found checking for System V shared memory ... found checking for struct msghdr.msg_control ... found checking for ioctl(FIONBIO) ... found checking for struct tm.tm_gmtoff ... found checking for struct dirent.d_namlen ... not found checking for struct dirent.d_type ... found Configuration summary + using PCRE library: /usr/local/src/pcre-8.00 + using system OpenSSL library + md5: using OpenSSL library + using sha1 library: auto/lib/sha1 + using system zlib library nginx path prefix: "/usr/local/nginx" nginx binary file: "/usr/local/sbin/nginx" nginx configuration prefix: "/usr/local/nginx" nginx configuration file: "/usr/local/nginx/nginx.conf" nginx pid file: "/usr/local/nginx/nginx.pid" nginx error log file: "/usr/local/nginx/logs/error.log" nginx http access log file: "/usr/local/nginx/logs/access.log" nginx http client request body temporary files: "/usr/local/nginx/temp/client_body" nginx http proxy temporary files: "/usr/local/nginx/temp/proxy" nginx http fastcgi temporary files: "/usr/local/nginx/temp/fastcgi" The warning "checking for gcc builtin atomic operations ... not found" shows that my default compiler gcc 4.1.2 20080704 does not support atomic operations.

Nginx reverse proxy crash when dns unavailable

by masom

Hi, I am currently planning to use nginx on several thousand devices as a reverse-proxy caching system. It currently work as expected (thanks Igor!), caches files as they are being requested by the devices. The only problem we hit is when nginx starts faster than the dns sytem is available on the units. Nginx will crash saying it is unable to connect to the remote host being proxied. 1739#0: host not found in upstream "content.dev.local" in /usr/local/nginx/conf/nginx.conf 33 Staring nginx again and it work (as the DNS is now responding properly). Any idea on how to work around this or should i fill a bug report (Nginx shouldn't crash when the remote is not available, but should try on requests to access it). Nginx does not die when the remote drops and come back (by pulling the network cable for example). It only crash when nginx is launched and the dns sytem is not yet available.

gzip compression not working

by Christian Billen

Hello, I have a fresh new installation of nginx on ubuntu 8.04 (installed via apt-get, I believe it is 0.5.x something) In my nginx.conf file I have gzip turned on, now I wanted to do a basic test and serving a static html file, but the file does not come compressed at all. Here's the snippet of configuration, I tried variations on this without success gzip on; gzip_min_length 1100; gzip_buffers 4 8k; gzip_proxied any; gzip_types text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript; gzip_http_version 1.1; gzip_comp_level 6; Does anyone have any idea why nothing is compressed? I've used this http://www.gidnetwork.com/tools/gzip-test.php and others to test the results. Thank you so much!

Good log analysis tool for nginx?

by Rt Ibmer

Can anyone recommend a good log analysis tool that is a good match for nginx? I'd like something that is flexible, where I can tell it which fields in the format are for which parts of the data (i.e. user agent is field 6) etc. Thanks! Note that I am looking for a SERVER SIDE tool to process the nginx logs (JavaScript based analytics tools will not work for this particular application).

Resize & cache image from 3rd-party server?

by digitala

Is it possible to obtain an image from a remote http server, resize it locally, and cache it locally using just nginx? I understand this would be possible using the perl module (maybe forking perl so nginx doesn't block), but I'm assuming it would be faster for nginx to do it "natively". If the better route *is* perl, I'd still like to know if/how it could be done using just nginx - mainly as it will help my (and hopefully others) understanding of the nginx internals. Thanks!
