I'm currently develloping an extension in Typo3 10.4 and I can't working out a problem
I'm using some external libs for mailing or payments which sometimes throw exceptions.
My problem is that when this is happening i got an OOPS error even if I try to catch the exception
for exemple :
//CODE BEFORE
try{
//SOME CODE WHO SENDS EMAIL AND SOMETIMES THROW EXCEPTION
//BECAUSE THE CONNECTION FAILED
}catch(Exception $e){
//DO SOMETHING
}
//CODE AFTER
And it's a pretty annoying problem because some DB actions are not completed then
I'm sure there is a way to deal with the exception without stopping all the script but i don't know how...
Can someone help plz?
Thanks guys
Your approach is correct and TYPO3 shouldn't interfere. Thus, there seems to be another issue, so a few things to consider here:
Please keep in mind that your TYPO3 extension code is namespaced, if you really catch(Exception $e) it means \Your\Namespace\Exception - you probably want catch(\Exception $e).
That said, additionally configure a way to show the exception stack trace instead of "Oops" as output (the more simple approach, see e.g. How do I enable Error Reporting in TYPO3?) or connect a remote debugger like xdebug (more advanced) in order to see more than the Oops and get the real cause of the error and how it propagates.
If you aren't able to change the actual TYPO3 system you work on for reasons, an alternative could be to use an easy to set up local dev system like DDEV. This offers a simplified way to create a local TYPO3 instance, see e.g. the TYPO3 blog article

In using realbrowserlocusts class it appears that I'm limited in any exception handling.
The only reference that partially works is: self.client.wait.until(EC.visibility_of_element_located ....
In a failed condition where the element is not found the script simply starts over again. With the script I'm working with I need to maintain a solid session state; I need to throw and exception(report an error), log the user out and then let the script start over again. I've been testing out the behavior with the locust.py script that Nick B. created with several approaches to "try, except" and they work running without realbrowserlocusts (selenium only) but with it the execution just stops.
Any examples would be greatly appreciated.
In its current format I've been able to run 3x the amount of a browser-based load per/agent/slave than our commercial tool. My goal is to replace it with a locust/selenium approach.
locust-plugins's WebdriverUser has a little bit better exception handling I think. A failure to find an element will log a failed request and if you use RescheduleTaskOnFail (as in the the example) it will restart the task when that happens.

I'm using MultipartObjectAssembler to upload data from a Database to OCI object storage.
Is there a way to know the reason for failure when using multipart upload?
When I try to commit assembler I'm getting IllegalStateException with the message "One or more parts were have not completed upload successfully".
I would like to know why any part got failed? I couldn't find a way to get this information from SDK.
try {
assembler.addPart(new ByteArrayInputStream(part, 0, length),
length,
null);
assembler.commit();
} catch (Exception e) {
assembler.abort();
throw new RuntimeException(e.getMessage());
}
Edit: I need to get an Exception thrown by a failed part and propagate the error message.
Is there a reason you are not using the UploadManager? It should do everything for you, including adding parts and committing. Here's an end-to-end example: https://github.com/oracle/oci-java-sdk/blob/master/bmc-examples/src/main/java/UploadObjectExample.java
If, for some reason, you cannot use UploadManager, please take a look at its source code nonetheless, since it demonstrates the intended usage of MultipartObjectAssembler: https://github.com/oracle/oci-java-sdk/blob/master/bmc-objectstorage/bmc-objectstorage-extensions/src/main/java/com/oracle/bmc/objectstorage/transfer/UploadManager.java#L175-L249
You create the MultipartObjectAssembler:
MultipartObjectAssembler assembler =
createAssembler(request, uploadRequest, executorServiceToUse);
You create a new request. This gives you back a MultipartManifest, which will later let you check if parts failed.
manifest =
assembler.newRequest(
request.getContentType(),
request.getContentLanguage(),
request.getContentEncoding(),
request.getOpcMeta());
Then you add all the parts:
assembler.addPart(
ProgressTrackingInputStreamFactory.create(
chunk, progressTrackerFactory.getProgressTracker()),
chunk.length(),
null);
Then you commit. This is where your code currently throws. I suspect not all parts have been added.
CommitMultipartUploadResponse response = assembler.commit();
If something goes wrong, check MultipartManifest.listCompletedParts(), MultipartManifest.listFailedParts(), and MultipartManifest.listInProgressParts(). The manifest should tell you what parts failed. Unfortunately not why; for that, you can enable ERROR level logging for com.oracle.bmc.objectstorage.transfer (for the class com.oracle.bmc.objectstorage.transfer.internal.MultipartTransferManager in particular).
If I have misunderstood something, please let me know. In that case, a larger, more complete code snippet would help me debug. Thanks!
I'm running an MVC app on Azure. I use the AzureReader2 plugin. It's been working fine for years.
But when this hits missing images, it throws FileNotFoundException exception and this apparently breaks down user authentication, causing user to be redirected to login page.
Is there a way to prevent this? How can I catch and handle this exception for the URL API?
I am considering the Image404 plugin. But I am not sure it works with AzureReader2 plugin (?)
Exception handling would be best for me as I could take some other actions.
Thanks
You can see the Image404 plugin source code on GitHub. There is a Config.Current.Pipeline.ImageMissing event that it handles - you can plug into the same event to do your own logic.
It should work fine with AzureReader2.
Note that most likely your 404 page is set to require authentication, which is why it is redirecting.
I am wondering if my code will work for catching a load error and if it is safe to attempt a reload. Since it is loading from my server I am assuming all files exist and the load error is just "something going wrong with networking".
m_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, LoaderComplete);
m_loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, LoaderError);
m_loader.load(new URLRequest("MyFile.png"));
private function LoaderError(e:Event):void
{
//Try to reload
m_loader.load(new URLRequest("MyFile.png"));
}
My two questions are as follows
1) Will IOErrorEvent.IO_ERROR catch all of the possible networking errors that can happen when downloading a file.
2) Is it okay to just attempt another reload?
Thanks in advance.
1 - Yes it will catch most network errors, you might also want to check SecurityErrorEvent.SECURITY_ERROR but that probably will happen all the time if you don't have a proper crossdomain.xml file
2 - It is okay to attempt another reload but that might fail too, what I usually do is try to reload once and if that fails use a default image that I created in code. This way your program can still function even if it fails to load some images due to network problems.
I have installed the sfErrorNotifierPlugin. When both options reportErrors/reportPHPErrors reportPHPWarnings/reportWarnings are set to false, everything is ok. But I want to catch PHP exceptions and warnings to receive E-mails, but then all my tasks fail, including clear-cache. After few hours of tests I'm 100% sure that the problem is with set_exception_handler/set_error_handler.
There's a similar question:
sfErrorNotifierPlugin on symfony task but the author there is having problems with a custom task. In my case, even built-in tasks fail.
I haven't used sfErrorNotifierPlugin, but I have run into 'The “default” context does not exist.' messages before. It happens when a call is made to sfContext::getInstance() and the context simply doesn't exist. I've had this happen a lot from within custom tasks. One solution is to add sfContext::createInstance() before the call to sfContext::getInstance(). This will ensure that a context exists.
There's an interesting blog post on 'Why sfContext::getInstance() is bad' that goes into more detail - http://webmozarts.com/2009/07/01/why-sfcontextgetinstance-is-bad/
Well, the problem could not be solved this way, unfortunately. Using sfErrorNotifierPlugin, I have enabled reporting PHP warning/errors (apart from symfony exceptions) and this resulted in huge problems, e.g. built-in tasks such as clear-cache failed.
The solution I chose was to load the plugin only in non-task mode (project configuration class):
public function setup()
{
$this->enableAllPluginsExcept('sfPropelPlugin');
if ('cli' == php_sapi_name()) $this->disablePlugins('sfErrorNotifierPlugin');
}
WHen a task is executed, everything works normally. When an app is fired from the browser, emails are sent when exception/warning occurs (maybe someone will find it useful).
Arms has explained the problem correctly. But usually context does not exist when executing backend/maintenance tasks on the console. And it is easier if you handle the condition yourself.
Check, if you really need the context?
If you do, what exactly do you need it for?
Sometimes you only want a user to populate a created_by field. You can work around by hard-coding a user ID.
If you want to do something more integrated, create a page (which will have a context) and trigger the task from there.
you can test the existance of the instance before doing something inside a class. Like:
if(sfContext::hasInstance())
$this->microsite_id = sfContext::getInstance()->getUser()->getAttribute('active_microsite');
I've been experiencing the same problem using the plugin sfErrorNotifier.
In my specific case, I noticed a warning was raised:
Warning: ob_start(): function '' not found or invalid function name in /var/www/ncsoft_qa/lib/vendor/symfony/lib/config/sfApplicationConfiguration.class.php on line 155
Notice: ob_start(): failed to create buffer in /var/www/ncsoft_qa/lib/vendor/symfony/lib/config/sfApplicationConfiguration.class.php on line 155
So, checking the file: sfApplicationConfiguration.class.php class, line 155,
I've replaced the ' ' for a null, then the warnings disappears, and also the error!
ob_start(sfConfig::get('sf_compressed') ? 'ob_gzhandler' : ''); bad
ob_start(sfConfig::get('sf_compressed') ? 'ob_gzhandler' : null); good
