 ma27 | so, the yarn berry fetcher was merged just in time... | 13:04:38 |
 hexa | ok, apparently we have docs on that | 13:04:41 |
 Emma [it/its] | wait we support yarn berry now?????????????? | 13:04:53 |
| hexa | yes!!!!!!!!!!!!!!!!!!!!!! | 13:05:00 |
| Emma [it/its] | mfw draupnir rejected it because yarn berry wasnt reproducible or something | 13:05:12 |
| Emma [it/its] | or inconsistent | 13:05:19 |
 emily | yes, someone had to write a reproducible fetcher for it | 13:05:55 |
| emily | which nobody did for months | 13:07:11 |
| emily | (are all the projects that switched to pnpm going to suddenly switch to yarn now? can we start writing a reproducible fetcher for whatever the next trendy JS thing is going to be in advance?) | 13:07:55 |
| hexa |
Internally, this uses a patched version of Yarn to ensure git dependencies are re-packed and any attempted downloads fail immediately.
| 13:08:52 |
| hexa | 🙃 | 13:08:57 |
| Emma [it/its] | oh ffs | 13:09:20 |
| emily | it's yarn's fault that they don't support an offline mode (or record hashes for platform-specific deps) | 13:11:04 |
| emily | thankfully the work was put in | 13:11:15 |
| emily | the fetcher will tell you if you need to run a command to get the missing hashes | 13:12:18 |
| emily | Cargo is less silly about this, so our deterministic Cargo fetcher doesn't need extra hashes. | 13:12:40 |
| hexa | except for git deps 😛 | 13:12:57 |
| emily | no, our new fetcher handles those. | 13:17:20 |
| emily | Cargo does record hashes for them | 13:17:26 |
| hexa | huh | 13:17:31 |
| emily | those hashes should all be gone from the tree now | 13:17:34 |
| emily | previously we explicitly banned them because Cargo changed their format in the past, making it unstable | 13:17:48 |
| emily | but then Cargo changed the format for all packages and we switched over to our own deterministic fetcher | 13:18:01 |
| hexa | ok | 13:18:21 |

| hexa | geez, why is the lockfile incomplete in that regard | 13:30:16 |
