Denis Magda commented on IGNITE-4120:
-------------------------------------
Review notes for the example:
- rename it to {{TransactionDeadlockDetectionExample}}.
- expand example's summary to the following
"This example demonstrates the usage of transaction deadlock detection
mechanism. The feature significantly simplifies debugging and fixing of
distributed deadlock that may be produced by your code. To enable the feature
you should start an Ignite transaction with a specific timeout and catch
TransactionDeadlockException that will contain extensive information that will
help out to fix a deadlock that may happen during execution of your code. To
read more about this feature refer to this page
https://apacheignite-net.readme.io/v1.7/docs/transactions#deadlock-detection-in-pessimistic-transactions";
- rephrase "">>> Transaction deadlock example started." to ">>> Transaction
deadlock detection example started."
- according to the documentation [1] the {{TransactionDeadlockException}} is
passed as {{CacheException.InnerException}} while you catch and process
{{TransactionDeadlockException}} directly in the example. Please adjust the
documentation aligning both it and the example.
{code}
catch (TransactionDeadlockException e)
{
// Printing out the helpful message prepared by the deadlock detection
mechanism in order to help out with the deadlock debugging.
Console.WriteLine("\n>>> Transaction deadlock in thread {0}: {1}", threadId,
e.Message);
}
{code}

> .NET: documentation and example for deadlock-detection mechanism
> ----------------------------------------------------------------
>
> Key: IGNITE-4120
> URL: https://issues.apache.org/jira/browse/IGNITE-4120
> Project: Ignite
> Issue Type: Sub-task
> Components: platforms
> Reporter: Denis Magda
> Assignee: Vladimir Ozerov
> Fix For: 1.8
>
>
> Presently the documentation and example about the deadlock detection
> mechanism are missing on .NET side. Let's fill this gap.
> - Documentation can be taken from Java side
> https://apacheignite.readme.io/v1.7/docs/transactions#deadlock-detection-in-pessimistic-transactions
> - The example scenario should be the following:
> -- start two threads inside of Ignite.NET process;
> -- each thread will start its own pessimistic transaction with timeout up to
> 10 seconds;
> -- the transactions must get to a deadlock;
> -- after the timeout expiration one of the transactions must succeed while
> the other must print out deadlock related information taking it from
> {{TransactionDeadlockException}}
