kandi X-RAY | trace Summary
A procedural macro for tracing the execution of functions. Adding #[trace] to the top of functions, mods, or impls will insert println! statements at the beginning and the end of the affected functions, notifying you of when that function was entered and exited and printing the argument and return values. Useful for quickly debugging whether functions that are supposed to be called are actually called without manually inserting print statements. See the examples directory and the documentation for more detail on how to use and configure this library.

I have two grid setup's
Local grid setup (hub and nodes are running in my local machine) and my
local machineconnected tonetwork#1VM grid setup (hub and nodes are running in my virtual machine) and my
virtual machineconnected tonetwork#2
When I execute the scripts I need to pass the IP address as a parameter. Here,
I can run my scripts successfully in local machine(code is available in local machine) by passing the network#1 IP address but if I pass the network#2 IP address (VM IP address) to local machine then I am getting below exception,
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
As per my knowledge, hub and nodes should be connected to same network. Cannot we run the scripts by passing the VM IP address to local machine?

...ANSWER
Answered 2021-Jun-15 at 13:57Yes, the exception occurred due to firewall. The ping test is successful from local machine to VM but not from VM to local. I contacted the organization network administrator to confirmed this.
QUESTION
The Question
How do I best execute memory-intensive pipelines in Apache Beam?
Background
I've written a pipeline that takes the Naemura Bird dataset and converts the images and annotations to TF Records with TF Examples of the required format for the TF object detection API.
I tested the pipeline using DirectRunner with a small subset of images (4 or 5) and it worked fine.
The Problem
When running the pipeline with a bigger data set (day 1 of 3, ~21GB) it crashes after a while with a non-descriptive SIGKILL.
I do see a memory peak before the crash and assume that the process is killed because of a too high memory load.
I ran the pipeline through strace. These are the last lines in the trace:
ANSWER
Answered 2021-Jun-15 at 13:51Multiple things could cause this behaviour, because the pipeline runs fine with less Data, analysing what has changed could lead us to a resolution.
Option 1 : clean your input dataThe third line of the logs you provide might indicate that you're processing unclean data in your bigger pipeline mmap(NULL, could mean that | "Get Content" >> beam.Map(lambda x: x.read_utf8()) is trying to read a null value.
Is there an empty file somewhere ? Are your files utf8 encoded ?
Option 2 : use smaller files as inputI'm guessing using the fileio.ReadMatches() will try to load into memory the whole file, if your file is bigger than your memory, this could lead to errors. Can you split your data into smaller files ?
If files are too big for your current machine with a DirectRunner you could try to use an on-demand infrastructure using another runner on the Cloud such as DataflowRunner
QUESTION
In my iOS app "Progression" there is rarely a crash (1 crash in ~1000+ Sessions) I am currently not able to fix. The message is
Progression: protocol witness for TrainingSetSessionManager.update(object:weight:reps:) in conformance TrainingSetSessionDataManager + 40
This crash points me to the following method:
...ANSWER
Answered 2021-Jun-15 at 13:26While editing my initial question to add more context as Jay proposed I think it found the issue.
What probably happens? The view where the crash is, contains a table view. Each cell will be configured before being presented. I use a flag which holds the information, if the amount of weight for this cell (it is a strength workout app) has been initially set or is a change. When prepareForReuse is being called, this flag has not been reset. And that now means scrolling through the table view triggers a DB write for each reused cell, that leads to unnecessary writes to the db. Unnecessary, because the exact same number is already saved in the db.
My speculation: Scrolling fast could maybe lead to a race condition (I have read something about that issue with realm) and that maybe causes this weird crash, because there are multiple single writes initiated in a short time.
Solution: I now reset the flag on prepareForReuse to its initial value to prevent this misbehaviour.
The crash only happens when the cell is set up and the described behaviour happens. Therefor I'm quite confident I fixed the issue finally. Let's see. -- I was not able to reproduce the issue, but it also only happens pretty rare.
QUESTION
I am using the Unit of Work patterns and want to a value back from the database to make sure it has updated the database successfully. Is there a way to do that?
...ANSWER
Answered 2021-Jun-15 at 13:25When you call SubmitChanges(), a transaction is created.
All objects that have pending changes are ordered into a sequence of objects based on the dependencies between them. Objects whose changes depend on other objects are sequenced after their dependencies.
Immediately before any actual changes are transmitted, LINQ to SQL starts a transaction to encapsulate the series of individual commands.
Using the default conflict resolution mode (FailOnFirstConflict), the entirety of your changes fail to save when an error is occurred because the transaction encapsulating all your changes is rolled back.
That means that if your submission succeeds, you can be sure your unit of work was completed. You do not need to get a value back to determine whether or not your changes were saved.
You could also set the conflict resolution mode to ContinueOnConflict if you have changes that you know do not depend on each other and you want all changes to be attempted even if one or more fail.
QUESTION
I've got a requirement to be able to copy a blob from a container in 1 storage account into a container in another storage account. Previously the source container had public access set to 'Container'. I was using the connection string to connect to the account and then get a reference to the blob.
I'm using StartCopyAsync(sourceBlob). This was originally working fine when the container had public access set to container. Now it throws a StorageException of 'The specified resource does not exist'. Is this a permissions thing? I would have expected an error message to say I didn't have permissions. I can see the resource is there in the container.
Assuming it is a permissions thing, is there a way to copy a blob from a container that has public access set to 'private'? The docs suggest it can be done by 'authorised request' but what how do you do that?
Update
I've tried Gaurav Mantri's suggestion but currently getting an error of "This request is not authorized to perform this operation". Here's my code:
...ANSWER
Answered 2021-Jun-11 at 23:55It is indeed a permission issue. For copy blob operation to work, the source blob must be publicly accessible. From this link:
When your container's ACL was public, the source blob was publicly accessible i.e. anybody could directly access the blob by its URL. However once you changed the container's ACL to private, the source blob is no longer publicly accessible.
To solve your problem, what you need to do is create a SAS URL for the source blob with at least Read permission and use that SAS URL in your StartCopyAsync method.
QUESTION
I wanted to upgrade a TYPO3v9 installation to TYPO3v10. After running through all the upgrade steps, I facing this issue "Page Not Found - The page did not exist or was inaccessible. Reason: The requested page does not exist". This error is thrown for every single pages in the installation.
My installation is multi-lingual with German as default and English as second language.
The most confusing part is that the same database runs fine with TYPO3 v9 source! Yes, to find the error, I have created 2 virtual TYPO3 websites in my local web server with one using TYPO3 v9 source and the other with TYPO3 v10 source. I also updates the "sites" configuration accordingly.
I also checked the Apache logs, but there is no trace of any error. So, it is entire TYPO3 v10 issue that I am unable to locate. The "Reports" section of TYPO3 v10 module is also of no help in this regard!
I do not know if anybody faced this kind of strange problem. It is really strange that a TYPO3 db runs great in version 9, but not in version 10.
Any suggestions will be of great help.
...ANSWER
Answered 2021-Jun-13 at 05:25Just a wild guess here, but please make sure, that the Url (especially the protocol!) for the page is set correctly in the site configuration. If it is set to https://yoursite.com and you call the page via http://yoursite.com there is no site with the url you are calling thus no page can be found.

ANSWER
Answered 2021-Jun-15 at 06:17You are violating the JPA spec by accessing the persistence context in a lifecycle listener.
See the JPA Specification 4.2 Section 3.5.2
In general, the lifecycle method of a portable application should not invoke EntityManager or query operations, access other entity instances, or modify relationships within the same persistence context. A lifecycle callback method may modify the non-relationship state of the entity on which it is invoked.
"a portable application should not" is the specification way of saying: Don't do that, anything might happen. Maybe the world ends.
The fix is not to do that. Maybe be preloading the currently logged in user and reference it so you may access it in your entity listener and do not set a reference to the user, but simple store its id or similar.
