.net - WCF Proxy Submit Crash - Kills Process -

-

i have simple wcf service accept data (wshttpbiding) , returns result. on client side dll containing proxy wrapper loaded , used build/submit request service.

this works in majority of cases, few users, submit call client proxy results in immediate crash of application (no errors, warnings, etc - process dies instantly)

the issue appears related users windows account: different users logged same machine not experience issue.

looking thoughts on might start looking culprit. ideas out there?

edit:

  1. i'm trying version trace statements , error logging in out affected machines @ moment. there no try/catch around .submit call, shouldn't exceptions propogate through call stack (the client/proxy dll being loaded directly primary app domain other exceptions such timeouts handed host application expected)
  2. web.config on server side below
  3. the users in same domain other users, default credentials being used. in house app, server on same network.

service web.config:

<system.servicemodel>     <behaviors>         <servicebehaviors>             <behavior name="services.eventsbehavior">                 <servicemetadata httpgetenabled="true" />                 <servicedebug includeexceptiondetailinfaults="true" />                 <servicethrottling maxconcurrentsessions="100" />             </behavior>             <behavior name="services.layoutsbehavior">                 <servicemetadata httpgetenabled="true" />                 <servicedebug includeexceptiondetailinfaults="true" />             </behavior>         </servicebehaviors>     </behaviors>     <services>         <service behaviorconfiguration="services.eventsbehavior" name="services.events">             <endpoint address="" binding="wshttpbinding" contract="services.ievents">                 <identity>                     <dns value="localhost" />                 </identity>             </endpoint>             <endpoint address="mex" binding="mexhttpbinding" contract="imetadataexchange" />             <host>                 <timeouts opentimeout="00:00:45" />             </host>         </service>         <service behaviorconfiguration="services.layoutsbehavior" name="services.layouts">             <endpoint address="" binding="wshttpbinding" bindingconfiguration="largerequestmsg" contract="services.ilayouts">             <identity>                 <dns value="localhost" />             </identity>             </endpoint>             <endpoint address="mex" binding="mexhttpbinding" contract="imetadataexchange" />         </service>     </services>     <bindings>         <wshttpbinding>             <binding name="largerequestmsg" maxreceivedmessagesize="5000000"></binding>         </wshttpbinding>     </bindings> </system.servicemodel>

update: (2011/03/18) i've been able little testing (finally) , unfortunatly can't reproduce issue using test harness on client machine.

this leads me believe there funky going on in calling client dll (via com) causing issue.

any thoughts?

to more info, try turning on wcf trace, , using trace viwer utility read teh error messages, in case source wcf operation. here's link on how this, it`s not complicated. please note trace file can large. dont keep trace on more time need collcet data. (a dev machine ideal here, if possible)

one more thing, immediate crash no warning, because error happends on thread other gui`s main thread. (so wcf call indeed place start looking).

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
