Questions about Custom Translation provider implementation
I've run into a few items I'm unsure of when building out my custom translation provider.
How is the CanTranslate method used?
How is the GetTargetLanguages method used?
I'm getting a StackOverflowException when I the Cancel method of the JobService api is triggered. Any idea why? It appears to be stuck in a loop, as I see a number of log entries with "[ 0] Calling Provider" that originate from Jumoo.TranslationManager.Core.Services.TranslationJobService. There are no loops in my logic for this, though I do have the logic in a service that's initialized in the constructor of the provider instead of directly inside the provider class, as I need to expose a few of the methods for use with an api. See below for relevant code.
From Provider
public StrakerTranslationProvider(TranslationManagerContext translationManagerContext, ILogger logger) {
_logger = logger;
_strakerService = new StrakerService(ApplicationContext.Current, translationManagerContext, this.Alias, logger);
}
...
public Task<TranslationAttempt<TranslationJob>> Cancel(TranslationJob job) {
return _strakerService.Cancel(job);
}
yeah sorry, about this we are working on the documentation to hopefully make this whole process easier for people
1 & 2. CanTranslate and GetTargetLanguages are not currently called by Translation Manager but the intention is that they will be used as part of the sending process to check if the target/source languages are valid for the provider.
if practical your provider should return true if the provider can translate a job from the source language into the job target language., but just not implementing them at the moment shouldn't cause any issues.
3: Looking at the code, is it the async stuff?
You should be able to change the provider to :
public async Task<TranslationAttempt<TranslationJob>> Cancel(TranslationJob job) {
return await _strakerService.Cancel(job);
}
As for #3, I tried changing it to async, but the issue persists. I suspect there is an issue with the job sent to the service, as I don't encounter this issue with the xliff provider. Below is the job data sent to the job service.
Sorry, I have come around and looked at the code in the original post again
You don't need to call _jobService.Cancel() when your provider/service gets its cancel called. That is the actual function that is calling your provider so you are stuck in a loop.
If you don't actually need to do anything to via own Service your cancel in the provider can just return success
public Task<TranslationAttempt<TranslationJob>> Cancel(TranslationJob job)
{
return Task.FromResult(TranslationAttempt<TranslationJob>.Succeed(job));
}
This will just return to TM which will cancel the job.
If you need to not let the cancel happen then return a Failed attempt and that will halt the cancellation process in Translation Manager.

Hi Jesse,

You should be able to change the provider to :
Noted on #1 and #2. That makes sense.
As for #3, I tried changing it to async, but the issue persists. I suspect there is an issue with the job sent to the service, as I don't encounter this issue with the xliff provider. Below is the job data sent to the job service.
One potential issue I see is that the NodeCount is 0 when there are nodes in the Nodes property. I'm unsure why that is happening though.

Thanks Kevin. That was the issue.
