Hey there,

as a guide writer, there are two things I would like to see before I make my guide a WJ install:

1. A popup window both in the beginning and the end of the install process, where I can write my own notes and thoughts and so on, could possibly write something about this specific list, and in the end just a goodbye note or so.

2. the previously discussed self-paced (click to see next) slideshow of the mods that are being installed, with a button to get to the mod page, if possible a link to the mod authors donations as on their mod page, and a button to instantly endorse the mod.

This would mean that all users read what I have to say about my mod pack and they see all mods and have a low threshold to see their mod page (recognition of the author), donate, and give endorsements. Plus guide authors can put their own donation page at the end.

All in all, this would probably make me switch to MO2 (from Vortex) and WJ, as I see no ethical conflict anymore and the main complaints are met (recognition and financial issues).

Is your feature request related to a problem? Please describe.
When creating an autoinstaller with WJ, sometimes it fails during the link checking process due to an error with the .meta file for a file, however, the log file shows the last mod that was checked successfully but not the mod that caused the error. One can assume that the mod that caused it should be the next in the stack after the last one successful, but sometimes this is not the case and the culprit could have been in a parallel process and threw the error late.

This happens for errors like:
System.Net.Http.HttpRequestException: Response status code does not indicate success: 404 (Not Found).

C:\oss\Wabbajack\Wabbajack\Wabbajack.Common\Utils.cs:line 281
110.91 - Value cannot be null.
Parameter name: source - Can't continue

Describe the solution you'd like
Implement a catch to log what was the mod that actually threw the error.

Solution

Is your feature request related to a problem? Please describe.
I get bored while staring to the screen while wabbajack runs, and only being able to watch the progress bars and logs messages.

Describe the solution you'd like
It would be nice if while wabbajack does its thing (installing or downloading), that start showing the short mod notes and images from nexus in like a slideshare presentation. This will work only for mods stored on Nexus. Not synched because some mods donwload/install too fast, but like 5 secs for every mod and then cycles again to the first mod. This way people would have an idea of what it is actually installing

Describe alternatives you've considered
It can be a report to the end, but I probably won't read it because my hype to start playing.

Additional context

Is your feature request related to a problem? Please describe.
Lack of modularity or customization (not a time sensitive request) Long-term QoL change.

Describe the solution you'd like
For mods with multiple texture, color, difficulty, etc options, perhaps a more customizable UI for WJ allowing for the end user to choose options for mods within the modlist.

Describe alternatives you've considered
Perhaps allow end user to access parts of the FOMOD that wouldn't break the load order
On nexus sites with several files, the user would normally choose one that best fits their desired image. Perhaps WJ could be customized to access the site and give the end user the option of which preselected file they would like.

Additional context
Again, not an immediate issue by any stretch.

Is your feature request related to a problem?
When compiling a modlist it will fail if you have a patches.json or plugininfo.json in your mator smash profile directory.

Describe the solution you'd like
It would be nice if these files could be processed by wabbajack so they're included when it installs.

Describe alternatives you've considered
I'm going to remove them now, as I don't need them. That's suboptimal.

Additional context
I'm building an update to Lexy.

Is your feature request related to a problem? Please describe.
We currently verify that files aren't deleted when we build a modlist, but with large lists it's easy to quickly chew through the ~3000 API a day limit.

Describe the solution you'd like
Lets cache the results from the Nexus and only update them every 12 hours or so. Should we somehow embed all this info in a DB of sorts so we can start better track all the disparate data sources we're collecting? Maybe it's not yet the right time for that, but something to consider.

Describe the bug
sometime modlist authors put things directly in the data folder or the game but WJ don't detect that, it only detects files in the root directory of the game.

Additional context
What I did was to create manually a Game Folder Files in the MO2 with only the files I knew WJ won't recreate (to avoid the previous reported bug)

Solution
Leave This blank, it will be filled in by the developers.

Hey Halgari!

As the title already states: The mod recieved an update today to version 5.0. The modlist needs to be updated unfortunately.

When creating the installer for Lexy's guide, the SSE-Terrain-Tamriel.esm file is added but disabled (it needs to be disabled for a lot of finishing line steps). This leads to it not being present after the installer has been run.

Some way to say that you want this specific disabled mod added as a download, even though it is disabled in the MO2 profile.

Additional context
I will try to do a pull request if I could add that to the code.

Currently it's not clear if a process is working or failed. Let's make that a bit more clear.

Describe the bug
I was going step by step with youtube tutorial. After authorising Wabbajack to use Nexus here is what Wabbajack logged:

• getting nexus api_key please click authorize if a browser window appears
• building a list of archives based on the files required
• at Alphaleonis.Win32.NativeError.ThrowException (... a lot of text followed by next and last log)
• (3) The system cannot find the path specified: [nexus_link_cache\mod-info-SkyrimSE-6194.json] - Can't continue.

And I'm stuck. I tried reinstalling game (as well as switching from Skyrim SE to regular Skyrim with all DLCs) and MO2 and redownloading Wabbajack but it still does not work and gets stuck at the same point

Solution
Leave This blank, it will be filled in by the developers.

Describe the bug
Cathedral Assets Optimizer generates dummy ESPs that only exist to load a BSA. Wabbajack doesn't know what to do with these.

Solution
We can detect if a .bsa exists with the same name, and if the ESP is super small (< 100 bytes) it's safe to assume that the .esp is empty. If those conditions are met we can include the .esp verbatim.

Thought I'd try out making an Issue /w an enhancement tag as a discussion topic, rather than talking about it in the discord. A bit nicer for tracking our thought process on a specific issue as we discuss, and for looking back later.

We've gotten on the topic of potentially refactoring the threading model for processing installation/compilation steps. Namely, we want to try to utilize async/await to avoid deadlock/starvation issues.

Some reference articles:
https://medium.com/rubrikkgroup/understanding-async-avoiding-deadlocks-e41f8f2c6f5d
https://blog.stephencleary.com/2012/07/dont-block-on-async-code.html

Here's my brain dump of my current understanding of the WJ setup, and also possible alternatives to consider, and how they'd look.

Current setup as a baseline:

Set up a work queue collection, which lets consumers pull jobs to do in FIFO
X threads are spun up, based on number of cores
Each thread pulls a job off the queue, and runs it. Any Tasks encountered have .Result run on them to execute them to completion
queue is waited on until it has a new job to give, repeat

Simplified typical usage scenario for discussion:

One Thread/worker is desired/created: Thread T1
One Job needs to be done
Let's say this one Job internally utilizes two threads from the threadpool to achieve its goals.
(many async functions don't need to actually use background threads from the pool to get benefit, but let's say this one does)
The threads from the pool it uses we'll call T2, T3.
Let's also say that T3 is the thread that marks the final task as complete.

new Thread /w Result (current setup):

T1 is a new thread
T1 pulls job off queue
T1 runs job /w .Result
T1 blocks while T2/T3 pool threads do their jobs. T2 finishes its stuff, T3 does as well, and marks the task complete.
T3/T2 are done, and released back to the pool
T1 unblocks with the result
T1 waits for another job from the queue

Task.Run() /w Result:

T1 is a thread from the threadpool
T1 pulls job off queue
T1 runs job /w .Result
T1 blocks while T2/T3 pool threads do their jobs. T2 finishes its stuff, T3 does as well, and marks the task complete.
T3/T2 are done, and released back to the pool
T1 unblocks with the result
T1 waits for another job from the queue

Dangerous
Since the X threads we are starting are now from the threadpool, our .Result calls block threads from that pool. This could help lead to starvation of the pool.

Task.Run() /w await

T1 is a thread from the threadpool
T1 pulls job off queue
T1 runs job /w await
T1 has nothing to do while T2/T3 pool threads do their jobs.
T1 is released back to the pool. Might even start working on some random work
T2 finishes its stuff, T3 does as well, and marks the task complete.
T2 has nothing to do and is released back to the pool
T3 is the thread that completed the task, and there's no assigned scheduler, so it's in charge of the continuation
T3 waits for another job from the queue

This might seem weird at first, as now T3 is the "worker" thread pulling this off the queue, and now T1 is just back in the pool not being used. But this is actually intended, and one of the cool parts of the async/await system. T1 was not doing anything while waiting for T2/T3 to be done, so it was released back to the pool to do any more potential work. When T3 is done, we can either wake up T1 again to finish the work, but why should we? Just do it on T3.. it was going to be put back into the pool anyway. T1 might be busy with something else for all we know.

This is different than when a task is done /w a scheduler assigned as in this scenario:

GUI thread /w await

T1 is the GUI thread. Has a scheduler
T1 pulls job off queue
T1 runs job /w await
T1 has nothing to do while T2/T3 pool threads do their jobs.
T1 is the GUI thread, /w a scheduler, so it goes and starts working on other GUI events on its scheduler queue (updating textboxes, executing button presses, whatever)
T2 finishes its stuff, T3 does as well, and marks the task complete.
T3 is the thread that completed the task, but there's an assigned scheduler, so it puts the continuation work onto the scheduler's queue. T2/T3 are then released to the pool
T1 finishes all the pending GUI updates in its queue, finally gets to the scheduled work continuation, and waits on the queue for another work item

This wouldn't be a setup we'd want, but more just an example of how schedulers interact /w the task system, making any continuation work queue up on them instead of being finished by the background thread.

Rx powered

Less sure on this route, but I'm sure it's possible.. I just haven't done anything similar myself yet.

Saw this article,
https://stackoverflow.com/questions/8558835/rx-extensions-where-is-parallel-foreach
which makes me think it would look something like this:

var jobQueue = new Subject<Func<Task>>();
jobQueue
    .Select(job => Observable.Defer(() => Observable.Start(job, Scheduler.ThreadPoolScheduler)))
    .Merge(5 /* at a time */)
    .Subscribe();

// Put stuff on the queue
jobQueue.OnNext(...);

Might not be right whatsoever, but that's where I'd be starting to test with, and going from there.

I think what we want is the Task.Run() /w await solution, or the Rx solution.

For the Task.Run() /w await solution, what's important isn't that we have X threads that are worker threads that live through the life of the program in charge of that job. What's important is that at any given point in time, up to X pool threads are working on queue items. Or.. if there's nothing on the queue, there will be zero pool threads blocking to wait on the queue.. but rather X tasks currently waiting on the queue to get a new item. If there's a blast of work to be done, those X "wait for next queue item" tasks complete, bringing up X threads from the pool to start doing their stuff.

This is at least my understanding of Task mechanics. I might be wrong in some of the theory, so I'd want to test extensively. Namely.. I'd be interested in the case where there's no work to be done, and now there's a lot, do X threads actually spin back up? Or does 1 thread wake up, /w X continuations to complete all chained together? I'm unsure, so I'd want to test.

Rx solution sounds tempting too. You know I'm an addict.

Some mods have archives inside archives, and we could also consider BSAs as an archive type, this would allow us to handle cases where users have unpacked BSAs or installed files from nested archives.

Describe the solution you'd like
We extend the indexer to handle nested archives, then extend the installer to do the same. It'll be tricky as we'll have to extract files to disk temporarily. Some archives, like BSAs are gigabytes in size, so we can't extract them into memory while we work with them, we'll need to write them to disk, extract what we need, then clean them up afterwards.

When validating links we're calling the download endpoint for the Nexus which makes it look like we're rapidly downloading a lot of files. We should switch to using the info endpoint.

Additional context
We originally used the download endpoint to check if a link was valid because this would throw an error on a missing file. We tried using the file info endpoint, but this would return files that weren't valid to download. Talked to the Nexus devs and they said until something better is implemented we can use a null category value as a flag for a deleted file.

Just to centralize and discuss ideas about having the modlist as separate file.
Pros :

• One central binary that everyone can trust and hosted modlists that use that binary
  Cons:
• Modlists potentially not compatible across versions of the exe, possibly confusing users

Current proposals:

• Json/XML file with a header field mentioning the version used to create the modlist
• Script file with a list of instructions to run
• Others?

I'll edit this if anyone posts any other proposals.

I think the bug is because the autoinstaller generates some folders inside the MO2 folder like the "LOOT Config Files" with some files the user has to manually relocate for their installation. If one tries to build a new modlist using the same MO2 folder and let this files, it will get the error.

I solved the error, deleting that folder. Probably it would happen if the user keeps the folder "Game Folder Files".

When updating a modlist already installed, you only need to download certain files and some minor/medium adjustments to your already installed mods. But if you try to use the new installer, it will delete all your installation and it will start again.

Describe the solution you'd like
To have a separation between downloading step and installing step, like two buttons, where you choose what process start. This way you won't hurt your installation and you will be able to download the new files.

Describe alternatives you've considered
Also to be able to add a changelog to the installations will help.

Additional context
For the updating purposes, it would be nice to print out what changes would be made if the installation continues, in order to make them manually.

Please list your OS (Win 10, Win 7, etc.) and Game type (SSE, FO4, etc.)

Solution
Warn before creating the autoinstaller about the presence of those files and refuse to build the autoinstaller.

Not really a feature request, but more of a pattern suggestion to make the code more robust and succinct that you guys might find useful.

I noticed that the RaisePropertyChanged calls typically look like this:

public string Mode
{
    get => _mode;
    set
    {
        _mode = value;
        OnPropertyChanged("Mode");
    }
}

I've got two small suggestions to consider:
1) nameof() concepts for when strings need to match a member/function name
So something like

public string Mode
{
    get => _mode;
    set
    {
        _mode = value;
        OnPropertyChanged(nameof(Mode));
    }
}

This is a bit more robust, as now if anyone uses a refactoring tool to rename Mode, the string passed to OnPropertyChanged is powered by the compiler now, and implicitly changed by the refactor. Helps avoid future gotcha magic string bugs.

2) RaiseAndSetIfChanged function might be useful to utilize:

protected void RaiseAndSetIfChanged<T>(
    ref T item,
    T newItem,
    [CallerMemberName] string propertyName = null)
{
    if (EqualityComparer<T>.Default.Equals(item, newItem)) return;
    item = newItem;
    this.RaisePropertyChanged(propertyName);
}

Might put it in some common base class like ViewModel? Either way, would be used to simplify the above code to something like this:

public string Mode
{
    get => _mode;
    set => RaiseAndSetIfChanged(ref _mode, value);
}

Makes my first suggestion kind of moot, haha.

I definitely love refactoring, so I can set up a PR with these suggestions completed.. but I felt like I should pitch the idea and see what you guys thought before spending time on it. Especially since the changes would touch a good amount of existing files I think. 8)

Describe the bug
The cleanup vfs staged files step fails for files that were readonly inside their archives.

Solution
Manually reset the attributes of all extracted files.

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
Left and right buttons (< and > maybe?) that allow you to navigate the slideshow

Describe alternatives you've considered

Additional context
N/A

Describe the bug
The program won't start. Tried running it in and outside of the MO2 folder. Tried all compatibility settings. Tried restarting PC. I can see the process starting for 1 second on Task Manager's details tab alongside "WerFault.exe".

Additional context
Windows 10 1903 64bit

Solution
Leave This blank, it will be filled in by the developers.

Is your feature request related to a problem? Please describe.
Currently the modlists will run through the entire process by only asking for the game directory.

Describe the solution you'd like
I would like the option to have process stop at each step (checkbox maybe?) and then manually click to continue. This is incase I am using the machine at the same time and want the extraction/installation to run when I want it to.
Steps at which it should stop or wait should be after Download and after extraction.

Describe alternatives you've considered
Currently I shutdown the program when I notice that its near the end, if I need to use the computer for something else at the same time.

Additional context
Not a high priority requirement, just nice to have for people with older/slower machines.
