The reason Racket is trying to recompile the OpenSSL files is because of a hash mismatch. This can be seen by enabling debugging output: $ PLTSTDERR=debug raco setup openssl Which says a lot of things, but most interestingly it says: -------------------------------- ... compiler/cm: checking: /gnu/store/jx0bkmaafb8fq0mqs5ywgnxq8rbpn8j1-racket-6.12/share/racket/collects/openssl/libcrypto.rkt compiler/cm: different src hash...

When the package is built, the path to OpenSSL gets hard-coded in a source file. The SHA-1 hash for this file is stored in its “.dep” file. When the output is grafted, the source file gets updated with a new OpenSSL path, but the hash does not get updated. This makes Racket think that the cached bytecode file is incorrect (even though it was likely grafted too), and it tries to recompile it. It fails because it tries to write this new bytecode file to the store. I double checked this by trying with an ungrafted Racket, and got better results. (There was still a warning about writing to the store, but it seemed less significant.) The only thing I can think of for a fix would be to patch Racket to be more lenient with bytecode files in the store. That is, ignore hash mismatches in store-files. I might give this a try later tonight if nobody has any better ideas. -- Tim ^ permalink raw reply [flat|nested] 10+ messages in thread

I guess it has to compile a bit of native code, so it needs a compiler.

I believe that the correct solution to these types of issues would be to recompute the hashes, and provide the updated hashes to the packages relying on them, so that they know the correct hash of the grafted file. In the gdb case this seems to be easier to solve, as the problem occurs inside a single package.

The other writing to the store issues still seem to persist, but it doesn't block running "raco setup" (after a "raco pkg install", a step I had omitted earlier). ISTM that this is a separate bug.

I was confused about the “raco setup” example, but the other step makes more sense now. I will say that even on Debian, with an regular user, I have seen “permission denied” errors because Racket tries to update files in “/usr/share”. > ISTM that this is a separate bug.

Does that seem fair? (Feel free to contact me > off-list.) Actually I think there is only one bug, which is the grafts thing. This bug was originally about compiling OpenSSL files to the store. Grafting doesn’t break OpenSSL it just makes Racket try to recompile its OpenSSL FFI wrappers. I have a patch, too. I sent it to guix-patches, but I must have made a mistake because it ended up in bug-guix attached to this bug report. The patch can be found at <https://debbugs.gnu.org/30680>. Also, the attachment didn’t get sent to the list, but did make it to the bug page. Hm.... Sorry for the goof! ^ permalink raw reply [flat|nested] 10+ messages in thread

Okay... on that note, "raco pkg install" now completely works IME without permission errors, I should mention. I'm still seeing a couple of permission errors on "raco setup", but they don't look like they matter unlike the ones that were appearing earlier. And you're right, I tried on Debian and got some errors too.
