I have ported the patch to Racket 7.0, the modified version is attached. It gets rid of all the store-related error messages I got when installing packages with raco, so as far as I am concerned the bug is indeed fixed. BTW, the patch (to Guix) for updating Racket to 7.0 is at https://debbugs.gnu.org/32355 (but does not yet include this patch to Racket). Thanks a lot for resolving this issue! Konrad.

If Racket is updated by grafting, the source and bytecode files get updated, but the checksum stays the same. Since the checksum no longer matches the source file, Racket tries to regenerate the bytecode and write it to the store, causing errors because the store is immutable. This patch makes Racket ignore checksums for files in the store. See <https://debbugs.gnu.org/30680> for details. --- collects/compiler/private/cm-minimal.rkt | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/collects/compiler/private/cm-minimal.rkt b/collects/compiler/private/cm-minimal.rkt index a5a5407..15af6b8 100644 --- a/collects/compiler/private/cm-minimal.rkt +++ b/collects/compiler/private/cm-minimal.rkt @@ -7,6 +7,7 @@ racket/list racket/path racket/promise + racket/string openssl/sha1 setup/collects compiler/compilation-path @@ -543,6 +544,10 @@ #f (list src-hash recorded-hash))) +(define (store-reference? path) + (let ([store-prefix (or (getenv "NIX_STORE") "/gnu/store")]) + (string-prefix?
