The ngx_accept_mutex_held don't need to be unset here.  The ngx_accept_mutex_held is used as an idicator that on previous iteration the lock was held by the process, and unsetting it will result in incorrect behaviour.> Also applies to; src/os/win32/ngx_process_cycle.c> line 507-508, 3 lines added;> 504 if (ngx_processes[n].handle != h) {> 505 continue;> 506 }> 507> --+ if(*ngx_accept_mutex.lock==ngx_processes[n].pid) {> --+ *ngx_accept_mutex.lock=0;> --+ }> 508 if (GetExitCodeProcess(h, &code) == 0) {> 509 ngx_log_error(NGX_LOG_ALERT, cycle->log, ngx_errno,> 510 "GetExitCodeProcess(%P) failed",> 511 ngx_processes[n].pid);> 512 }This patch is also wrong.  In the current state of the win32 version it is not assumed that accept mutex is used at all.  But if it is, correct aproach to unlock shared memory mutexes on abnormal process termination is to port (or move to platform-independed place) the ngx_unlock_mutexes() function from src/os/unix/ngx_process.c.  It correctly uses ngx_shmtx_force_unlock() to properly unlock shared memory mutexes using atomic operations.Note well that unlocking shared memory mutexes on abnormal process termination is an emergency mechanism.  If it actually happens, it indicate that something is really wrong in other places of the system.Please also consider reading http//nginx.org/en/docs/contributing_changes.html.-- Maxim Douninhttp//nginx.org/en/donation.htmlFrom mdounin at mdounin.ru  Mon Dec  2 134522 2013From mdounin at mdounin.ru (Maxim Dounin)Date Mon, 2 Dec 2013 174522 +0Subject fastcgi_buffering and caching from FastCGI serverIn-Reply-To <1385974141.885235384.is0nnm9l@frv34.ukr.net>References <1385974141.885235384.is0nnm9l@frv34.ukr.net>Message-ID <20131202134521.GU93176@mdounin.ru>Hello!On Mon, Dec 02, 2013 at 105705AM +0200, wishmaster wrote> > Hi, devel team!> > Playing with caching responses from FCGI server I've found not > documented issue.

The nginx server proxy the http request to Amazon ELB (elastic load balancer) using upstream module. Currently we are seeing timeout issues in NGINX because NGINX caches the IP address on start. Now when there is change in IP address of ELB, NGINX doesn't updates it's IP and still point to old IP. We went through many post on internet and tried setting resolver to AWS DNS server, resolver timeout to 20s, valids to 30 sec. defining variable instead of direct name in proxy pass, request URL in proxy pass but nothing has worked for us. NGINX is not honoring the resolver and corresponding TTL settings.Some of the blogs also says that they have tried similar things and nothing works for them. IT looks to me like this is bug in NGINX and will be resolved only by changing the source.Has anybody found solution to this problem?

The nginx server proxy the http request to Amazon ELB (elastic load balancer) using upstream module. Currently we are seeing timeout issues in NGINX because NGINX caches the IP address on start. Now when there is change in IP address of ELB, NGINX doesn?t updates it?s IP and still point to old IP. We went through many post on internet and tried setting resolver to AWS DNS server, resolver timeout to 20s, valids to 30 sec. defining variable instead of direct name in proxy pass, request URL in proxy pass but nothing has worked for us.

But this is not ideal solution.Can you paste the relevant part of your nginx configuration here?If that's about re-resolving server names in an upstream server group, then yes - there's nosuch functionality in nginx at this time.Still, if you're using proxy_pass to a "single server" instead of an upstream server group,re-resolving works. That might be a workaround since you appear to proxy to a singleentry-point which is terminated on ELB?Please check,http//nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_pass("If a domain name resolves to several addresses, all of them will be used in a round-robin fashion.")Also,"A server name, its port and the passed URI can also be specified using variables    proxy_pass http//$host$uri;or even like this    proxy_pass $request;In this case, the server name is searched among the described server groups, and, if not found, is determined using aresolver."Hope this helps> I am seriously thinking of moving to Apache Http server if this problem doesn?t get resolved.)> Regards,> > Shankar> > _______________________________________________> nginx mailing list> nginx at nginx.org> http//mailman.nginx.org/mailman/listinfo/nginxFrom www at lc365.net  Tue Dec  3 113220 2013From www at lc365.net (=?gb2312?B?ufnV8cGi?=)Date Tue, 3 Dec 2013 193220 +0800Subject [ANN] Windows nginx 1.5.8.1 CaterpillarIn-Reply-To <82f08a63fed0ac7d3fefdf3b8752ac2d.NginxMailingListEnglish@forum.nginx.org>References <82f08a63fed0ac7d3fefdf3b8752ac2d.NginxMailingListEnglish@forum.nginx.org>Message-ID <SNT149-W88FBA0F07460B528DC51F7E3D50@phx.gbl>Dear, Thank you very much for your great job!

Proper patch to solve the problem is to be coded.As the problem can be easily resolved by using symmetrical session cache configuration (better yet, using a single session cache at http level), it's not a high priority task.> So far I have blocked nginx updates.Looks like a silly thing to do.

Is this possible at all? If so, could you point me to a sample/module which does this so I can learn from it?Many thanks,Alex       -------------- next part --------------An HTML attachment was scrubbed...URL <http//mailman.nginx.org/pipermail/nginx/attachments/20131203/79e7b4f7/attachment.html>From nginx-forum at nginx.us  Tue Dec  3 182000 2013From nginx-forum at nginx.us (Peleke)Date Tue, 03 Dec 2013 132000 -0500Subject Subdomains no longer workIn-Reply-To <20131127231035.GB15722@craic.sysops.org>References <20131127231035.GB15722@craic.sysops.org>Message-ID <1afd6e9946388553fe017b15c1823b13.NginxMailingListEnglish@forum.nginx.org>It worked sometime before that subdomains were accessible as they should be,now they are not anymore but sadly I don't know why because I haven't testedthem with every change.The config seems to be valid.nginx is running on a Debian Wheezy server with PHP 5.5x, memcache and a fewother services.I don't know why it serves the main domain as it should but no subdomains.ThanksPosted at Nginx Forum http//forum.nginx.org/read.php?2,244807,245173#msg-245173From francis at daoine.org  Tue Dec  3 203009 2013From francis at daoine.org (Francis Daly)Date Tue, 3 Dec 2013 203009 +0000Subject Subdomains no longer workIn-Reply-To <1afd6e9946388553fe017b15c1823b13.NginxMailingListEnglish@forum.nginx.org>References <20131127231035.GB15722@craic.sysops.org> <1afd6e9946388553fe017b15c1823b13.NginxMailingListEnglish@forum.nginx.org>Message-ID <20131203203009.GM15722@craic.sysops.org>On Tue, Dec 03, 2013 at 012000PM -0500, Peleke wroteHi there,> I don't know why it serves the main domain as it should but no subdomains.What happens if you comment the line  listen []80 ipv6only=on;and restart?If your response is anything other than "it works", please show onerequest that you make, what response you get, and what response youexpect.The output of  curl -v http//adminer.domain.tld/will probably help.f-- Francis Daly        francis at daoine.orgFrom ianevans at digitalhit.com  Tue Dec  3 211303 2013From ianevans at digitalhit.com (Ian Evans)Date Tue, 03 Dec 2013 161303 -0500Subject Any config tricks to stop site from framing  us?Message-ID <11fcffb2663578b4ba9f3fa3e8f4c5bc@digitalhit.com>Yesterday, I discovered that someone had registered a site (basically taking our domain name and adding a word to it) and then framed our whole site in theirs.
