v9: Publisher AppId/AppKey generation

[PhyxionNL]

Describe the bug Generating an appid/appkey doesn't seem to work correctly at the moment. If I open dev tools I can see json getting returned with a bunch of keys, but this is not shown anywhere to the user, and uSync doesn't seem to use the generated keys either (at least it's not shown in the UI).

Version (please complete the following information):

• Umbraco Version: 9 rc 2
• uSync Version 9 rc 2
• uSync.Complete Version 9 beta 5

[KevinJump]

HI, sorry for this - but for later builds this functionality is/has been changed quite a bit in later builds.

For the public beta it was still in there, but we have since taken the decision that we are not going to change appsettings from the UI (the new release will show you what to put where in the file, but it will not setup the server in the same way as v8 does

we do have later nightly builds on our public nightly server - but these are not super stable at the moment, but if you want to check things. :

https://pkgs.dev.azure.com/jumoo/Public/_packaging/nightly/nuget/v3/index.json

[PhyxionNL]

No problem @KevinJump, I thought I'd just report a few issues I've came across. I already expected some would be fixed. I think that's a better solution. I had already added that NuGet feed but it doesn't seem to serve nightly builds of the complete edition (only normal uSync + dependencies).

[PhyxionNL]

@KevinJump Have you checked the NuGet feed? It's still not showing nightly builds here for Complete (and most others).

[KevinJump]

HI, yeah sorry the code wasn't in an ideal state there for a few days while we took the chance to reactor a few things.

the nightlies are back now - currently version 9.0.0-beta005.20210917.3 - works reasonably well - we are just tiding up a few loose ends before a likely RC next week .

[PhyxionNL]

Thanks. I just tried my first sync and there are some problems.

1. In root content node ("Content"), select server (pull), and nothing happens. This is logged in developer console:

2. Push also fails: TypeError: uSyncPublishDialogManager.openPublisherDialog is not a function

3. Some documents fail on Calculating .... with everything checked. For example, when I select some document > Do something else > Publish to... > select server > Calculating "document". It works with this config (both need to be unchecked): I don't see anything logged in console despite having "ReportDebug" on true.

4. Snapshots don't seem to do anything.

[KevinJump]

Hi,

:( - that all works for me on a clean install. Maybe i am forgetting something in the setup that needs to be documented.

you might need to increment the caching value in umbraco (to get the js/files etc reloaded).

also can you confirm what versions of everyhing (umbraco included) you are running,

and this will probibly/certainly not work on linux just at the moment .

[KevinJump]

yeah sorry - pull is broken. in that build. fixing now.

[PhyxionNL]

Here:

Umbraco.Cms" Version="9.0.0-rc003" uSync.Complete" Version="9.0.0-beta005.20210917.4"

I already cleared the cache. I'm not running it on Linux. I've gotten logging to work and it's hanging on this: [17:59:39 DBG] Checking for DocType Dependencies, Umbraco.ColorPicker.EyeDropper

[PhyxionNL]

Alright, I've saved the document type that used the eye dropper again and now it does get on with it. That said, calculating is super slow and waits a long time at the eye dropper (only one document uses it). MultiUrlPicker is also very slow. I tried to push from my root node ("Home") and it takes at least 15 minutes to calculate. There is not a whole lot of content (~120 documents) on the site. I will give the cache a try and see if it speeds things up. E: cache got filled after export, but doesn't seem to get saved between app restarts. Second try didn't put anything in the cache anymore, and rebuild neither.

Some other things (you might've seen it already):

1. Before "Publish to server", there's null before the URL:

2. Missing snapshot icons:

3. Snapshots I really can't get working. Nothing is logged in app and browser console either.

[PhyxionNL]

Got one to send, but it didn't succeed. This is thrown on receiving side:

System.IO.DirectoryNotFoundException: pack folder : umbraco\Data\TEMP\uSync\receive\ad5343ae-74bd-4703-85b3-4b3f5de8e052\uSync does not exsit when it should at uSync.Expansions.Core.Physical.SyncPackFileService.EnsurePackFolder(System.String folder) at offset 56 at uSync.Expansions.Core.Services.SyncPackService.ImportItems(uSync.Expansions.Core.SyncPackRequest request) at uSync.Publisher.Services.SyncPublishService.ImportItems(uSync.Publisher.Models.SyncPublishRequest request) at offset 14 at uSync.Publisher.Controllers.uSyncReceiveApiController.DoPublisherStep(uSync.Publisher.Models.PublisherActionRequest options, System.Func`2 action) at offset 127 at uSync.Publisher.Controllers.uSyncReceiveApiController.ImportPackFolder(uSync.Publisher.Models.PublisherActionRequest options) at offset 19

On sender: Remote Error: Redirect (/) Content: [] Which I suspect is happening as I handle unhandled exceptions by redirecting to the home page.

[KevinJump]

:( - the pull is going to be something i look at next week, after tracking it down, turns out i had put one of the zip to stream in .netcore methods into a to hard to do just now pile, and not then gone back (doh!).

other stuff, are you running on a published site (e.g dotnet publish) or a dev site. its not that slow for me, and pushing works, as does all the snapshot stuff, there is a chance i've messed things up.

you should double check that all the caching of files has been resolved by smidge. i think the cache buster for smidge defaults to version or something, so if you change it to AppDomain it will change on restart (so no cached js files).

in appsettings.json its something like (obviously with more config in umbraco than just this)

"Umbraco": {
      "RuntimeMinification": {
        "cacheBuster": "AppDomain"
      }
}

No problem, I'll give that a try then.

Both, the receiving end is published, the sender is just running the build locally (without debugger). Without logging it's a bit faster but not much. Maybe 2 minutes faster.

"Umbraco": {
      "RuntimeMinification": {
        "cacheBuster": "AppDomain"
      }
}

I had already removed all cached files from Smidge to try. I use a custom cache buster for Smidge based on last modified file, but even when Smidge is disabled it's not working.

[KevinJump]

HI,

• we've fixed pull!,
• and added some logging for the dependency stuff ! - so if you have uSync logging turned to debug (Add "uSync": "Debug" to the overrides seection of the serilog config in appsettings.json). you should see some timings for the dependency check which will hopefully help pinpoint any issues

also in an effort to help you see whats going on, I am going to try and log the changes we are making for nightlies : https://github.com/Jumoo/uSync.Complete.Issues/blob/main/log/nighly.md

[PhyxionNL]

Thanks @KevinJump. A changelog is useful.

I have installed 9.0.0-beta005.20210918.8. If I press Remote (Pull) at the root dashboard the Umbraco.Cms.Core.Udi exception is still printed in browser console and nothing happens after it. Local (Push) is also broken, the "Push selection" button isn't doing anything. Publishing and pulling through "More actions" does work if I start it from the same content item. The Sync page from Publisher page fails here with "Error while processing SettingsPull - (pullFetch/Calculate/0/)":

Snapshot creation ignores the root folder I have set in app settings. Apply and Report of a snapshot does not show any progress: In app console I do see progress being made (with Debug to Serilog). After this all is done there is a final changes report shown on the browser dashboard. Snapshots settings saving does not work, but going by your previous replies, I suspect this will be removed.

[KevinJump]

Hi,

Snapshot and Browser (Remote(pull)/Local(Push) dashboard are fixed in the new build (9.0.0-beta005.20210920.2)

I am not sure the remote error was a UDI errors - but if they are still happening after this update - they are coming for the serialization phase (i think the problem is when its turned into JSON its not going via the umbraco UDI converter) - do you have any customization of serialization anywhere ?

[PhyxionNL]

Updated and the main dashboard is indeed working now (both push and pull), nice work 👍

I have also disabled redirects from /umbraco pages to get you the correct URL from the error on the Sync page: Error while processing SettingsPull - (pullFetch/Calculate/0/) - Remote Error: InternalServerError (/umbraco/uSyncReceive/uSyncReceiveApi/PullGetItems) Content: []

[KevinJump]

Hi, is there anything on the logs of the server you are pulling from around that error ?

[PhyxionNL]

I didn't have logging enabled there, but I've run it again, here:

[KevinJump]

Its a little strange because the SyncLanguageItemManager doesn't have a method with that signature 🤔 it might be coming from the internal umbraco methods . but i am not sure.

I've put some extra checks around languages in the latest build beta005.20210920.4 - might fix it, might also log some more info to tell us what is wrong

Ahh found it. on the sync dashboard, we where setting language UDI like a guid based on, when its actually a string based UDI.

fixed in beta005.20210920.5

It works now 🎉. With this I've also noticed that the recycle bin isn't properly synchronized. I removed some content locally from recycle bin and pushed the changes to remote, but the Sync page is now trying to pull the items back from the recycle bin from remote.

The rest all seems to work now (apart from the previously mentioned snapshot settings and initial progress for snapshot report/apply.

Closing this (moved recycle bin to new issue, which i just need to check)
