Request for hasql version compatibility update

[dasheng523]

I am writing to inquire about the possibility of updating Rel8's hasql dependency to support newer versions, specifically hasql >= 1.9.

Currently, Rel8 (version 1.6.0.0) depends on hasql >=1.6.1.2 && <1.9. This constraint creates a dependency conflict when trying to use Rel8 alongside hasql-pool versions that require hasql >= 1.9 (e.g., hasql-pool >= 1.3).

Thank you for your time and consideration.

I'll try to make a release soon. Until then you should be able to use the source from master since #372 is merged.

For cabal you would do this using a source-repository-package stanza and for stack you can do this with extra-deps

I am encountering a build error when trying to use Rel8 from the master branch (via source-repository-package in cabal.project).

The specific error messages are:

Conflicting exports for ‘text’:
   ‘Decoder(..)’ exports ‘Rel8.Type.Decoder.text’
     imported from ‘Rel8.Type.Decoder’ at src/Rel8.hs:500:1-24
     (and originally defined at src/Rel8/Type/Decoder.hs:36:5-8)
   ‘Encoder(..)’ exports ‘Rel8.Type.Encoder.text’
     imported from ‘Rel8.Type.Encoder’ at src/Rel8.hs:502:1-24
     (and originally defined at src/Rel8/Type/Encoder.hs:30:5-8)

Conflicting exports for ‘binary’:
   ‘Decoder(..)’ exports ‘Rel8.Type.Decoder.binary’
     imported from ‘Rel8.Type.Decoder’ at src/Rel8.hs:500:1-24
     (and originally defined at src/Rel8/Type/Decoder.hs:34:5-10)
   ‘Encoder(..)’ exports ‘Rel8.Type.Encoder.binary’
     imported from ‘Rel8.Type.Encoder’ at src/Rel8.hs:502:1-24
     (and originally defined at src/Rel8/Type/Encoder.hs:28:5-10)

This indicates that both Rel8.Type.Decoder and Rel8.Type.Encoder modules export fields named text and binary, leading to a naming conflict when Rel8.hs attempts to re-export Decoder(..) and Encoder(..).

This issue prevents successful compilation of projects using Rel8's master branch. Could you please investigate this conflicting export issue?

Thanks I'll take a look on Tuesday

The conflicting export issue should be resolved now on master

Looking at the recent PRs that landed, I see you are working on a new release of rel8. Thank you. To tide people over until it lands, would you be open to revising the metadata of the current release to allow hasql <1.10 on the library component but adding hasql <1.9 on the test-suite component? The hasql-1.9 ChangeLog says that the only backwards-compat-breaking change is in the way connection settings are passed, which does not affect the rel8 library.

We have been happily running with allow-newer:rel8:hasql since May, so it should be safe to do.

I've published a review. I'll also finish publishing the release
