How to continuously load a saved flow file from mitmproxy? (i.e. "follow"/-f the file)

I've saved a file with the --save-stream-file (save_stream_file) option.
Now I want to replay that as asked in my previous question, but I want it to continuously follow the saved "flow".
How can I do that?
This is a follow-up question of How to replay/show a saved flow in the console without triggering requests?.
After some asking I got around and this should do the trick:
tail -f ./mitmproxy-flow.cap | mitmproxy --rfile - -n
Thanks to #mhils!
Though, at least for me, v5.2 currently still has a bug where it crashes.

A weird error occurs on my xml-file during eclipse start and goes away after maven update

I have a weird error that occurs on my camel-config.xml file that occurs on my datasource pooling. When I start my eclipse, the error shows up that says "Processing XML Error. Resource must not be null", and goes away after I do maven update. I wanted to know what's causing the error to occur in the first place and why does it go away after I update it. Its oracle datapooling and not even related to logic of a particular project. Any thoughts, suggestions or views about this problem are appreciated.
I'm getting error on this piece of code.
<orcl:pooling-datasource id="dataSource1"
url="${oracle.db1.url}" username="${oracle.db1.username}" password="${oracle.db1.password}"/>
<orcl:pooling-datasource id="dataSource2"
url="${oracle.db2.url}" username="${oracle.db2.username}" password="${oracle.db2.password}"/>
<orcl:pooling-datasourc
e id="dataSource3"
url="${oracle.db3.url}" username="${oracle.db3.username}" password="${oracle.db3.password}"/>
Thanks,

Strange Xcode error

When I run my app, i get one error and i dont know how to fix it. Can someone help me?
Here is the error:
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1

Thanks
The causative problem is the error immediately preceding that one, the duplicate symbol error.
gcc-4.2 failed with exit code 1 Error Occurs due to some of your file or frame work are duplicated check it out which file is in you target link file or in your framework are repeated.
from your log message "didUpdate" may be repeated in your project look for that...
May be this is helpful to You.
From the error message, it seems like didUpdate is defined more than once in your code. Search for didUpdate on your workspace and make sure it's only being defined once.
Either you are redefining variable or you are probably importing a *.m file somewhere in your project.Try importing corresponding *.h file.

the svnpoller is not triggered (warning in the twistd.log)

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!

How can I validate an image file in Perl?

How would I validate that a jpg file is a valid image file. We are having files written to a directory using FTP, but we seem to be picking up the file before it has finished writing it, creating invalid images. I need to be able to identify when it is no longer being written to. Any ideas?
Easiest way might just be to write the file to a temporary directory and then move it to the real directory after the write is finished.
Or you could check here.
JPEG::Error
[arguments: none] If the file reference remains undefined after a call to new, the file is to be considered not parseable by this module, and one should issue some error message and go to another file. An error message explaining the reason of the failure can be retrieved with the Error method:
EDIT:
Image::TestJPG might be even better.
You're solving the wrong problem, I think.
What you should be doing is figuring out how to tell when whatever FTPd you're using is done writing the file - that way when you come to have the same problem for (say) GIFs, DOCs or MPEGs, you don't have to fix it again.
Precisely how you do that depends rather crucially on what FTPd on what OS you're running. Some do, I believe, have hooks you can set to trigger when an upload's done.
If you can run your own FTPd, Net::FTPServer or POE::Component::Server::FTP are customizable to do the right thing.
In the absence of that:
1) try tailing the logs with a Perl script that looks for 'upload complete' messages
2) use something like lsof or fuser to check whether anything is locking a file before you try and copy it.
Again looking at the FTP issue rather than the JPG issue.
I check the timestamp on the file to make sure it hasn't been modified in the last X (5) mins - that way I can be reasonably sure they've finished uploading
# time in seconds that the file was last modified
my $last_modified = (stat("$path/$file"))[9];
# get the time in secs since epoch (ie 1970)
my $epoch_time = time();
# ensure file's not been modified during the last 5 mins, ie still uploading
unless ( $last_modified >= ($epoch_time - 300)) {
# move / edit or what ever
}
I had something similar come up once, more or less what I did was:
var oldImageSize = 0;
var currentImageSize;
while((currentImageSize = checkImageSize(imageFile)) != oldImageSize){
oldImageSize = currentImageSize;
sleep 10;
}
processImage(imageFile);
Have the FTP process set the readonly flag, then only work with files that have the readonly flag set.
