fly launch hangs when reusing an existing (suspended) app name

Questions / Help
, ,
1

Not sure whether that is a bug. I did this:

  1. created an app named X, fly launch
    it failed deployment, left it on its own (pending)
  2. created another app, called Y, fly launch
    made it deploy successfully etc.
  3. edited that second app, to be named X, and ran fly launch
    → build hang, I had to kill the fly deploy command

To solve this, I went on and deleted the pending app (X) and did another fly launch
all worked fine that time.

that’s the. memory dump I got from that hanging builder:

Hi @Hirakosan, a crash isn’t expected behaviour so I’ve asked internally about this.

In the meantime: I’m not sure step 3 would be expected to update an existing app. Depending on which part of fly launch you wanted to redo, you’d probably either delete app X and launch again, or use fly deploy --app X to create new release of app X with the config (and source code) of app Y.

Thanks for the info. To be clear nothing crashed. Just hung for several minutes. Ctrl-c wouldn’t stop the command so i killed it.
