Question & Answer Builds

Description of the issue

Execution of ruby script fails with “abort trap: 6” error message.

Environment:

Where did the issue happen?
Bitrise iOS Xcode 8.2.x

Which build Step causes the issue and which version of the step?
Ruby script execution - any version

The script I’m trying to execute is the following (relevant bits):

require 'xcodeproj'

def change_bundle_id(project_name, target_name, project_configuration, project_filepath, new_bundle_ID)
  project_directory=File.dirname project_filepath

  puts "Parsing project at '#{project_filepath}'"
  project = Xcodeproj::Project.open(project_filepath)
  target = project.targets.find { |t| t.name == target_name }
  exit -12 if target.nil?

  configuration = target.build_configurations.find { |c| c.name == project_configuration }
  exit -12 if configuration.nil?

  puts "Setting Xcode Project's PRODUCT_BUNDLE_IDENTIFIER to '#{new_bundle_ID}'"

  configuration.build_settings['PRODUCT_BUNDLE_IDENTIFIER'] = new_bundle_ID
  puts "done!"
  project.save
  
  puts "done!!"
end

Reproducibility

The issue happens all the time.

Other stacks

The issue doesn’t appear when run locally with CLI

Hi @FWFabio,

Seems like a Ruby (gem?) issue - searching for “abort trap: 6”:

Seems like a memory allocation issue in the code somewhere.

3

That’s a generic error that happens when ruby crashes.
It works flawlessly on my machine via bitrise CLI, with the same ruby version so I have no idea how to fix it.

4

Can you try to replace the Ruby Script step, and instead store your ruby script into your repo and just run with with a normal/Bash script (the Script step), like:

#!/bin/bash
set -ex

ruby ./path/to/script.rb

?

Ah! I fixed by trying a different version of the xcodeproj gem!
Still unsure where the problem was, but a different version seems to work perfectly.

7

That was what I suspected too, that one of your dependency GEM versions had a memory allocation issue causing “abort trap: 6”, but I couldn’t pinpoint it.

Thanks @FWFabio for sharing the solution! Just a question: what was the faulty version and which version fixed it? Just for future ref. in case someone else would have this issue.

1.3.3 was failing. 1.4.2 works perfectly.

Thanks for the info @FWFabio, I’m sure it’ll help others in the future! :wink:
