Here's an idea: override Haskell's mkDerivation to add all of the function arguments to passthru. Since it's passthru, it shouldn't invalidate caching.
Otherwise, there's also this ugly hack.

Oh, you're saying to disable postPatch all together | 22:58:50 |
| alexfmpe | I guess that's usable | 22:59:21 |
| alexfmpe | I did think about shoving 'jailbreak' in passthru, but that only lets me read, not write right? | 23:00:28 |
| alexfmpe | doCheck works because the one I can set is the same mkDerivation will read | 23:00:49 |
| alexfmpe | passthru just 'mirrors' | 23:00:59 |
| alexfmpe | There's no pass-by-reference | 23:01:10 |

I guess that's usable As in, few false positivirs | 23:01:54 |
| alexfmpe | * As in, few false positives | 23:02:02 |
 Alex | Well you can override mkDerivation to completely ignore doJailbreak too. It's not entirely clear to me what you're trying to do. | 23:02:13 |

As in, few false positives Vanishingly few if I just sed out the jailbreak-cabal line | 23:02:44 |

Well you can override mkDerivation to completely ignore doJailbreak too. It's not entirely clear to me what you're trying to do. Brute force discovery of needless jailbreaks | 23:03:07 |
| alexfmpe | Find all jailbreaked ones, unjailbreak, attempt build of all, report the ones that worked | 23:03:38 |
| alexfmpe | Technically it can't report the ones whose deps failed, but doing it one at a time takes an eternity of eval | 23:04:23 |
| alexfmpe | * Technically it can't report the ones whose deps failed to build due to that change, but doing it one at a time takes an eternity of eval | 23:04:42 |

Well you can override mkDerivation to completely ignore doJailbreak too. It's not entirely clear to me what you're trying to do. I guess I could do this for a one off, but the idea is having a fire and forget script one can run whenever | 23:06:50 |
| alexfmpe | Rather than some patch to mkDerivation or generic-builder | 23:07:52 |
| alexfmpe | This is why I said 'from the outside' | 23:08:08 |
| alexfmpe | eh, I guess you could still have a .patch file and apply it from the script | 23:08:32 |
| alexfmpe | Think I can hack a 'getter' and 'setter' for jailbreak by doing invasive surgery to postPatch | 23:08:53 |
| alexfmpe | That lets me use the same overall shape I did for dontCheck hunting | 23:09:11 |

Rather than some patch to mkDerivation or generic-builder No patching is needed, it can be done like you'd override any other package in the Haskell set. | 23:53:12 |
| alexfmpe | not sure I follow | 23:54:08 |
| alexfmpe | how would I unset doJailbreak by overriding mkDerivation | 23:55:00 |
| alexfmpe | btw this is how I ended up detecting: v: lib.hasInfix "jailbreak-cabal" v.postPatch; | 23:55:39 |
| alexfmpe | stringly hack, but a decent first approximation | 23:56:07 |
| alexfmpe | also, I only want to do this for the ones for which it is set, otherwise mass rebuild | 23:57:16 |
| 23 Feb 2025 |
| alexfmpe | oh I see what you mean, override the jailbreak argument itself | 00:09:10 |
| alexfmpe | ok that's working | 00:26:13 |
| alexfmpe | get = v: lib.hasInfix "jailbreak-cabal" v.postPatch;
set = x: v: v.overrideAttrs(_: _: { jailbreak = x; });
reset = set false;
| 00:26:23 |
| alexfmpe | ok so it's building...511 packages, ouch
300 of which are amazonka ones | 00:28:58 |
