I'm trying to upload coverage reports to codecov.io using the codecov-bash script provided by Codecov. The bash script fails to run on Gitlab CI running an alpine:edge docker image.
Below is the error:
$ /bin/bash <(curl -s https://codecov.io/bash)
/bin/sh: eval: line 107: syntax error: unexpected "("
And here is the relevant part of my .gitlab-ci.yml file:
after_script:
- apk -U add git curl bash findutils
- /bin/bash <(curl -s https://codecov.io/bash)
Line 107 of the script is inside the show_help() function, just under This is non-exclusive, use -s "*.foo" to match specific paths.:
show_help() {
cat << EOF
Codecov Bash $VERSION

-h Display this help and exit
-f FILE Target file(s) to upload
-f "path/to/file" only upload this file
skips searching unless provided patterns below
-f '!*.bar' ignore all files at pattern *.bar
-f '*.foo' include all files at pattern *.foo
Must use single quotes.
This is non-exclusive, use -s "*.foo" to match specific paths.
-s DIR Directory to search for coverage reports.
Already searches project root and artifact folders.
-t TOKEN Set the private repository token
(option) set environment variable CODECOV_TOKEN=:uuid
-t @/path/to/token_file
-t uuid
-n NAME Custom defined name of the upload. Visible in Codecov UI
-e ENV Specify environment variables to be included with this build
Also accepting environment variables: CODECOV_ENV=VAR,VAR2
-e VAR,VAR2
-X feature Toggle functionalities
-X gcov Disable gcov
-X coveragepy Disable python coverage
-X fix Disable report fixing
-X search Disable searching for reports
-X xcode Disable xcode processing
-X network Disable uploading the file network
-X gcovout Disable gcov output
-X html Enable coverage for HTML files
-X recursesubs Enable recurse submodules in git projects when searching for source files
-N The commit SHA of the parent for which you are uploading coverage. If not present,
the parent will be determined using the API of your repository provider.
When using the repository provider's API, the parent is determined via finding
the closest ancestor to the commit.
-R root dir Used when not in git/hg project to identify project root directory
-F flag Flag the upload to group coverage metrics
-F unittests This upload is only unittests
-F integration This upload is only integration tests
-F ui,chrome This upload is Chrome - UI tests
-c Move discovered coverage reports to the trash
-Z Exit with 1 if not successful. Default will Exit with 0
-- xcode --
-D Custom Derived Data Path for Coverage.profdata and gcov processing
Default '~/Library/Developer/Xcode/DerivedData'
-J Specify packages to build coverage. Uploader will only build these packages.
This can significantly reduces time to build coverage reports.
-J 'MyAppName' Will match "MyAppName" and "MyAppNameTests"
-J '^ExampleApp$' Will match only "ExampleApp" not "ExampleAppTests"
-- gcov --
-g GLOB Paths to ignore during gcov gathering
-G GLOB Paths to include during gcov gathering
-p dir Project root directory
Also used when preparing gcov
-k prefix Prefix filepaths to help resolve path fixing: https://github.com/codecov/support/issues/472
-x gcovexe gcov executable to run. Defaults to 'gcov'
-a gcovargs extra arguments to pass to gcov
-- Override CI Environment Variables --
These variables are automatically detected by popular CI providers
-B branch Specify the branch name
-C sha Specify the commit sha
-P pr Specify the pull request number
-b build Specify the build number
-T tag Specify the git tag
-- Enterprise --
-u URL Set the target url for Enterprise customers
Not required when retrieving the bash uploader from your CCE
(option) Set environment variable CODECOV_URL=https://my-hosted-codecov.com
-r SLUG owner/repo slug used instead of the private repo token in Enterprise
(option) set environment variable CODECOV_SLUG=:owner/:repo
(option) set in your codecov.yml "codecov.slug"
-S PATH File path to your cacert.pem file used to verify ssl with Codecov Enterprise (optional)
(option) Set environment variable: CODECOV_CA_BUNDLE="/path/to/ca.pem"
-U curlargs Extra curl arguments to communicate with Codecov. e.g., -U "--proxy http://http-proxy"
-A curlargs Extra curl arguments to communicate with AWS.
-- Debugging --
-d Don't upload, but dump upload file to stdout
-q PATH Write upload file to path
-K Remove color from the output
-v Verbose mode

I've tried many things to solve the issue, but I can't find a solution. On their GitHub repo, there is this issue that seems linked but the proposed solution has not worked for me: Failing on busybox 1.26, incorrect flags passed to find.
You can find the full log of the job here, line 434: https://gitlab.com/gaspacchio/back-to-the-future/-/jobs/788303704
Based on KamilCuk's comment, below is the full line needed to properly upload code coverage reports to codecov:
bash -c '/bin/bash <(curl -s https://codecov.io/bash)'
As pointed out by KamilCuk, notice the closing '.
The -c flag is documented as such in the man pages for bash:
-c string
If the -c option is present, then commands are read from string. If there are arguments after the string, they are assigned to the positional parameters, starting with $0.
As of today, I don't know why this works. Feel free to edit this answer if you have any clues.
