It might happen that a crate fails to build repeatedly due to a docs.rs bug, clogging up the queue and preventing other crates to build. In this case it's possible to temporarily remove the crate from the queue until the docs.rs's bug is fixed. To do that, log into the machine and open a PostgreSQL shell with:
Then you can run this SQL query to remove the crate:
UPDATE queue SET attempt = 100 WHERE name = '<CRATE_NAME>';
To add the crate back in the queue you can run in the PostgreSQL shell this query:
UPDATE queue SET attempt = 0 WHERE name = '<CRATE_NAME>';
Sometimes the latest nightly might be broken, causing doc builds to fail. In
those cases it's possible to tell docs.rs to stop updating to the latest
nightly and instead pin a specific release. To do that you need to edit the
/home/cratesfyi/.docs-rs-env file, adding or changing this environment
Once the file changed docs.rs needs to be restarted:
systemctl restart docs.rs
To return to the latest nightly simply remove the environment variable and restart docs.rs again.
If a bug was recently fixed, you may want to rebuild a crate so that it builds with the latest version. From the docs.rs machine:
cratesfyi queue add <crate> <version>
This will add the crate with a lower priority than new crates by default, you can change the priority with the
After an outage you might want to add all the failed builds back to the queue. To do that, log into the machine and open a PostgreSQL shell with:
Then you can run this SQL query to add all the crates failed after
YYYY-MM-DD HH:MM:SS back in the queue:
UPDATE queue SET attempt = 0 WHERE attempt >= 5 AND build_time > 'YYYY-MM-DD HH:MM:SS';
Sometimes it might be needed to remove all the content related to a crate from docs.rs (for example after receiving a DMCA). To do that, log into the server and run:
cratesfyi database delete-crate CRATE_NAME
The command will remove all the data from the database, and then remove the files from S3.
Occasionally it might be needed to prevent a crate from being built on docs.rs, for example if we can't legally host the content of those crates. To add a crate to the blacklist, preventing new builds for it, you can run:
cratesfyi database blacklist add <CRATE_NAME>
Other operations (such as
remove) are also supported.
Warning: blacklisting a crate doesn't remove existing content from the website, it just prevents new versions from being built!
