Cannot read property 'commands' of undefined

[oliversalzburg]

I get a lot of Cannot read property 'commands' of undefined errors during a run.

[knownasilya]

Is this during rebases

[oliversalzburg]

No, I wasn't rebasing. This was a fresh setup of Strider in combination with GitLab.

[knownasilya]

Do you have a callstack? Would like to know which phase is triggering the error.

[oliversalzburg]

@knownasilya I don't seem to be able to repro right now. It happened in a fresh installation.

I'm only seeing this right now, but it's probably a different issue:

[oliversalzburg]

Seems like ensureCommand is missing semicolons btw.

[knownasilya]

@oliversalzburg most of the code is not following a specific style guide. I've been slowly following the airbnb guide as I make changes. Eventually I want to setup eslint and fix all the code O.O

[oliversalzburg]

Yeah, sorry for not collecting more useful information when the error happens.

Whenever I set up a fresh Strider instance, I seem to be running into all kinds of weird issues that resolve themselves shortly after. In those situations I'm usually under a lot of time pressure and am battling with multiple issues.

If it happens again, I'll make sure to capture more useful information.

[knownasilya]

@oliversalzburg can you walk me through how you setup gitlab with Strider (I don't use gitlab and the plugin is a little raw - adds to huge todo list)?

[oliversalzburg]

@knownasilya I can try and reproduce this later at home, but it was a process involving a lot of trial-and-error. I'm not sure if I'll remember making the same mistakes again ;D

[oliversalzburg]

@knownasilya So, I'm trying to reproduce this, but I'm running into Strider-CD/strider-gitlab#8 for now. I'll see if I can find the root of that one.

[oliversalzburg]

Alright, I got two more call stacks for the same error after setting up a fresh strider instance on my Windows desktop.

The git clone failed here, because I neglected to add the strider SSH key to GitLab though. But maybe this is already helping:

[oliversalzburg]

So, this is what I did (originally, I used our on-premise GitLab, but I would assume the public gitlab.com works just as well):

1. Clone strider git clone [email protected]:Strider-CD/strider.git
2. npm install
3. bower install
4. Set SERVER_NAME environment variable (http://localhost:3000)
5. Add initial user node .bin/strider addUser
6. Start strider node .bin/strider
7. Log into strider
8. Add GitLab account to my strider account
   • API URL is http://gitlab.com/api/v3
   • The private token can be retrieved from your gitlab.com user profile
9. Add a project from Gitlab to strider
   • Set it as a nodejs project
10. Configure the project
    • Set node_modules caching to strict
11. Deploy project

[knownasilya]

@oliversalzburg awesome! Thanks for hanging in there. This will make it much easier to debug.

[oliversalzburg]

I'm experiencing a similar issue right now that feels related.

I have set up all our projects fresh. When there are no builds running, I go to the project configuration and click Retest & Deploy, which sends me to the build page.

I have placed a breakpoint in the command.done handler of JobDataMonitor.prototype.statuses. Here, this.phase is undefined:

I can, however, not repro this issue at will. Partly due to #785

[oliversalzburg]

If I wait long enough I get a ton of these though. Here's more:

These all seem related and look like race conditions to me. I can't even tell where std is set on the job monitor.
