I am not sure what is going on, but i get this weird issue with buildbot.
The SVNPoller is configured as it should (checked various config example files), when i run the buildbot checkconfig it says that everything is fine....but it won't work at all.
If i trigger a build via the scheduler class it works fine, i can retrieve the source updates and build without problems (tried with a 1h timeframe).
The problem thou is that the poller is not working, so even if i build each hour, the changes column stays empty (i get the changes for the various versions thou, so if i click on the build detail i can see the sourcestamp carrying the right and most recent revision everytime that i modify the codebase); so I have no way to know if the build fails who did the last change.
Another peculiar thing is that in the twistd.log i see this line:
Warning: no ChangeSources specified in c['change_source']
And i am not sure why it wouldn't work since the checkconfig does not raise any error.
The result of this is of course that the only thing built is the hourly one, leaving me without the poller, and without knowing who is putting code in each build.
This is the code for the poller:
c['change source']=SVNPoller
(svnurl="svn+ssh://user#svnserver.domain.com/svn/project/trunk,
pollinterval=60*5,
histmax=10,
project=myproj,
svnbin = '/usr/bin/svn')
So far it looks good, so I am not really sure what is wrong here...why the SVNPoller is not triggering any build.
Anyone that has some suggestions about why is this happening ? Is there any other way to get changes from an SVN server? I am a total newbie at BuildBot and I am not really getting too much out of the manual; that looks much more like a scholastic book instead of being a manual that shows you how you do stuff :)
Thanks!!!!!
Ok, silly me :) the problem is the missing underscore on change_source...once added it the problem is solved
c['change_source'] = SVNPoller (svnurl=source_svn_url,
pollinterval=60,
histmax=10,
project='The_project',
svnbin= '/usr/bin/svn'
)
this will poll the svn codebase at source_svn_url (just put your svn:// path); and will check every minute to see if anyone has done changes; and will keep 10 changes in the record list (any change after the 10th will not show up so use it carefully if you do a lot of commits).
Hope that this helps who uses buildbot!

I am currently learning the UnrealEngine and made huge steps in less time.
I worked with version 4.25.1 for a while now and created a projekt in there without having any problems so far.
Yesterday I switched from version 4.25.1 to 4.26.0 (Prev2) and observed a strange behaviour.
In the older version I used "MultiSphereTraceByChannel" in one of my Actor-BluePrints and everything worked fine. Looping through the HitArrayResult gave me all hits of the tracer with specific objects.
Now in 4.26.0 it seems that it does not work properly anymore like before. Every hit returns an ImpactPoint of [0,0,0].
Here is a shortened example of my BluePrint:
So First I trace every hit with MultiSphereTraceByChannel with specific objects and then I try to render a sphere at each ImpactPoint of all found hits.
This worked in the older Version but does not now...
Does anyone have any Ideas/Suggestions/Questions?
To me it seems that something changed in the newer version which affects the MultiSphereTracer to work like it did before.
Sincerly

Edit:
This problem also happens with regular SphereTraceByChannel-Function!
After some investigations i found the problem/solution to this and it still bothers me that this happens in 4.26... The problems are the Start- and End-Vectors of the SphereTracer (doesn't matter which tracer).
In my example i use ActorLocation as Start- and(!) End-Vector which leads to this struggle. Now if i shift the vector like 1 unit on Z, everything workes fine again.
This is the correct way of the example above:
Works with both MultiSphere- and SphereTraceByChannel.
But it still bothers me why this happenes because now i have to change ALL SphereTracer and shift them by only 1 unit.
I am toying with the FluidEnter/FluidExit. So in a simple form, here is what I am trying to do:
I created in Main an empty population of agent called Terminal. For now, in Terminal, there is only a fluidEnter connected to a fluidExit (very simple)
enter image description here
Now, on startup, I want to fill this population and set up the proper connections (the terminals are ordered).
So, on startup, I call a function init(), whose body start with Terminal t = add_terminals(); (I have only one terminal for now, just toying with things)
In Main, obviously, I also have a fluidEnter and a fluidExit. I would like to connect the fluidExit of Main to the fluidEnter of the terminal t, and the fluidExit of the terminal t to the fluidEnter of Main, so code (still in init()) looks like
fluidExit.set_fluidEnter(t.fluidEnter);
t.fluidExit.set_fluidEnter(fluidEnter);
I get an exception so obviously, I am doing something wrong. Any idea?
I think the set_fluidEnter function is deprecated or just non-functional.
Instead, you should do:
fluidExit.connect(t.fluidEnter);
So just replace set_fluidEnter with connect... nothing else.
That should do the trick
I was going down the same path as you a couple of months ago. Yes... .connect() works great. It even works as a gate. If it is disconnected, then fluid stops at the exit. Once connected, fluid starts to flow again. It is very slick.
I'm using EF6 rc1 with Code First strategy, without precompiled views and the problem is:
If I compile and run the exe application it takes like 15 seconds to run the first query (that's okay, since I'm still working on the pre-generated views). But if I use Visual Studio 2013 Preview to Debug the exact same application it takes almost 2 minutes BEFORE running the first query:
Dim Context = New MyEntities()
Dim Query = From I in Context.Itens '' <--- The debug takes 2 minutes in here
Dim Item = Query.FirstOrDefault()
Is there a way to remove this extra time? Am I doing something wrong here?
Ps.: The context itself is not complicated, its just full with 200+ tables.
Edit: Found out that the problem is that during debug time the EF appears to be generating the Views ignoring the pre-generated ones.
Using the source code from EF I discovered that the property:
IQueryProvider IQueryable.Provider
{
get
{
return _provider ?? (_provider = new DbQueryProvider(
GetInternalQueryWithCheck("IQueryable.Provider").InternalContext,
GetInternalQueryWithCheck("IQueryable.Provider").ObjectQueryProvider));
}
}
is where the time is being consumed. But this is strange since it only takes time in debug. Am I missing something here?
Edit: Found more info related to the question:
Using the Process Monitor (by Sysinternals) I found out that there its the 'desenv.exe' process that is consuming tons of time. To be more specific its consuming time with an 'Thread Exit'. It repeats the Thread Exit stack 36 times. I don't know if this info is very useful, but I saved a '.cvs' with the stack, here is his body: [...] (edit: removed the '.cvs' body, I can post it again by the comments if someone really think its going to be useful, but it was confusing and too big.)
Edit: Installed VS2013 Ultimate and Entity Framework 6 RTM. Installed the Entity Framework Power Tools Beta 4 and used it to generate the Views. Nothing changed... If I run the exe it takes 20 seconds, if I 'Start' debugging it takes 120 seconds.
Edit: Created a small project to simulate the error: http://sdrv.ms/16pH9Vm
Just run the project inside the environment and directly through the .exe, click the button and compare the loading time.
This is a known performance issue in Lazy (which EF is using) when the debugger is attached. We are currently working on a fix (the current approach we are looking at is removing the use of Lazy). We hope to ship this fix in a patch release soon. You can track progress of this issue on our CodePlex site - http://entityframework.codeplex.com/workitem/1778.
More details on the coming 6.0.2 patch release that will include a fix are here - http://blogs.msdn.com/b/adonet/archive/2013/10/31/ef6-performance-issues.aspx
I don't know if you have found the solution. But in my case, I had similar issue which wasted me close to a week after trying different suggestions. Finally, I found a solution by changing my web.config to optimizeCompilations="true" and performance improved dramatically from 15-30 seconds to about 2 seconds.
This is a weird one. :)
I have a script running under Apache 1.3, with Apache::PerlRun option of mod_perl. It uses the standard CGI.pm module. It's a regularly accessed script on a busy server, accessed over https.
The URL is typically something like...
/script.pl?action=edit&id=47049
Which is then brought into Perl the usual way...
my $action = $cgi->param("action");
my $id = $cgi->param("id");
This has been working successfully for a couple of years. However we started getting support requests this week from our customers who were accessing this script and getting blank pages. We already had a line like the following that put the current URL into a form we use for customers to report an issue about a page...
$cgi->url(-query => 1);
And when we view source of the page, the result of that command is the same URL, but with an entirely different query string.
/script.pl?action=login&user=foo&password=bar
A query string that we recognise as being from a totally different script elsewhere on our system.
However crazy it sounds, it seems that when users are accessing a URL with a query string, the query string that the script is seeing is one from a previous request on another script. Of course the script can't handle that action and outputs nothing.
We have some automated test scripts running to see how often this happens, and it's not every time. To throw some extra confusion into the mix, after an Apache restart, the problem seems to initially disappear completely only to come back later. So whatever is causing it is somehow relieved by a restart, but we can't see how Apache can possibly take the request from one user and mix it up with another.
This, it appears, is an interesting combination of Apache 1.3, mod_perl 1.31, CGI.pm and Apache::GTopLimit.
A bug was logged against CGI.pm in May last year: RT #57184
Which also references CGI.pm params not being cleared?
CGI.pm registers a cleanup handler in order to cleanup all of it's cache.... (line 360)
$r->register_cleanup(\&CGI::_reset_globals);
Apache::GTopLimit (like Apache::SizeLimit mentioned in the bug report) also has a handler like this:
$r->post_connection(\&exit_if_too_big) if $r->is_main;
In pre mod_perl 1.31, post_connection and register_cleanup appears to push onto the stack, while in 1.31 it appears as if the GTopLimit one clobbers the CGI.pm entry. So if your GTopLimit function fires because the Apache process has got to large, then CGI.pm won't be cleaned up, leaving it open to returning the same parameters the next time you use it.
The solution seems to be to change line 360 of CGI.pm to;
$r->push_handlers( 'PerlCleanupHandler', \&CGI::_reset_globals);
Which explicitly pushes the handler onto the list.
Our restart of Apache temporarily resolved the problem because it reduced the size of all the processes and gave GTopLimit no reason to fire.
And we assume it has appeared over the past few weeks because we have increased the size of the Apache process either through new developments which included something that wasn't before.
All tests so far point to this being the issue, so fingers crossed it is!
All,
Is there a way to have a minimum time to keep a stream open before it closes? For some reason, my stream is closing prematurely which is causing errors elsewhere. I need to keep it open to make sure ALL of the data is gathered, and then it can run the other code.
Thanks,
James
In the case that someone falls upon this question later, I ended up creating nested if statements to pull it off.
Basically, there is one statement that checks if the end tag is not found (for my code, the END of the ENTIRE data that I should be receiving is </SessionData> - So, I did if([outputString rangeOfString:#"</SessionData>"].location == NSNotFound). I created a string called totalOutput that would have the outputString added onto the end of totalOutput until the </SessionData> is found.
If anyone ever needs help, just go ahead and comment on here and I can give more information.
