[naviserver-devel] ns_urldecode -charset

Hi, We're currently in the process of porting a fairly large code base from Aolserver to Naviserver for testing (using Naviserver v4.99.4 on Debian Squeeze). One thing that has come up so far is that ns_urldecode seems to have dropped the "-charset" switch. I'm assuming it used to be present sin

Hi, We're encountering an occasional problem which means calls to ns_proxy hang forever. It seems to be when an ns_proxy eval command timeouts during evaluation & it produces a large amount of output. Under those circumstances ns_proxy becomes inoperable. Following is a contrived test case which

Re: [naviserver-devel] ns_proxy hang

Has anyone got any ideas on debugging this issue? Turns out it's causing us many more operational issues that we first thought... Regards, -- David On 18 April 2017 at 15:44, David Osborne wrote: > Hi, > > We're encountering an occasional problem which means calls to ns_p

Re: [naviserver-devel] ns_proxy hang

The manifestation for us in production is quite insidious and difficult to spot the root cause of. Certainly not easy to see via the logs. One place we are experiencing it is in code which generates outgoing emails. Sometimes, when the outgoing email is particularly large, nsproxy times out while

Re: [naviserver-devel] ns_proxy hang

Thanks. This does indeed seem to fix the test case I sent - however I'm now getting a segmentation fault during the "make test". It's during the second ns_proxy 5.10 test (there are two 5.10s) - "test ns_proxy-5.10 {check killing active proxy}". ns_close is being called on an invalid SlavePtr du

Thanks Gustaf. We've tested and rolled this change out now and it's looking good. Regards On 15 May 2017 at 21:01, Gustaf Neumann wrote: > Am 15.05.17 um 17:54 schrieb David Osborne: > > In some cases (but not all), Ns_WaitProcess is logging an error > > immediately

Thanks very much Gustaf! We'll schedule a build and let you know how it goes. On 25 May 2017 at 11:32, Gustaf Neumann wrote: > > but i will be looking into this when times allows. > David, There are now some updates in the repository, removing falso > positives about zombies etc. for eval-timout

[naviserver-devel] "ns_server active" request IP - proxy aware?

Hi, We have a need for ns_server active & queued commands to be proxy-aware in the IP addresses that they report. Similar to how the access log IP address can be configured to report the X-Forwarded-For value (if it exists)

Re: [naviserver-devel] "ns_server active" request IP - proxy aware?

Hi, After an initial rollout we made a change to our code which massive increased the number of times ns_server is called with the -checkforproxy switch - we than started to get intermittent seg faults. I can reproduce this is test with gdb. It does seem to be related to the new section of code w

Re: [naviserver-devel] "ns_server active" request IP - proxy aware?

Thanks Gustaf, I can only really reproduce it by hammering my development instance using apache bench (and only with a concurrency level of >100 after a few hundred requests) - not very scientific. The purpose of the filter_dos_check filter is to examine the server load (via ns_server active) and

[naviserver-devel] Profiling

Hi, We've been looking at profiling the execution times of various application-level procs running NaviServer. We want the ability to turn on profiling for selected commands, so we started off using Tcl traces in a manner similar to: http://nikit.tcl.tk/page/Profiling+with+execution+traces So we
