Describe the bug
post-checkout-command
option for source-repository-package
option in the cabal.project file causes cabal to crash when the post-checkout-command
returns exit status 0. The correct behaviour should be to not crash and keep building.
To Reproduce
Create a new cabal project with a cabal.project
file with a post-checkout-command
. Here's I'm using hpack
:
with-compiler: ghc-9.0.1
packages:
./
source-repository-package
type: git
location: https://github.com/berberman/mustache
tag: 9d28fe2aa6578b15efcc4d00fdf97f015007127a
post-checkout-command: hpack
Run
$ cabal v2-build
Expected behavior
Cabal should fetch the source dependency, run the post-checkout-command
(hpack
), and then successfully build the project.
System information
- mac OSX
cabal
: 3.6.0,ghc
: 9.0.1
Additional context
The failure is caused by the code here. The correct code should be
unless (exitCode == ExitSuccess) $ exitWith exitCode
[Edit: the kind reporter provided a fix and it looks reasonable, so I think we can shortcut.]
Thank you for the report. Could somebody triage? Does it happen with a different GHC? With cabal 3.4? On Linux or Windows? Could somebody reproduce?
Huh, the wrong code snippet looks like a double negation. Always problems with that. :)
The broken code is from 13 months ago.
