alexcrichton · 2019-01-10T21:11:27Z

r? @steveklabnik

ehuss · 2019-01-10T22:42:25Z

Just a heads up, this will likely fail the license check. I think arrayref will need to be added to the exception list. I'm pretty sure the other dependencies will be ok, but I'm not certain.

Am I correct that this can't really be used until the print.html issue is solved?

jamesmunns · 2019-01-10T22:44:48Z

@ehuss I was not aware of the license check

jamesmunns · 2019-01-10T22:46:18Z

This may work for you, depending on how you are doing links. It does not work for the style the embedded-book uses, but I am not sure if your changes will have an issue.

You could rebase your changes on this PR, and try running python x.py test src/tools/linkchecker?

steveklabnik · 2019-01-11T21:34:53Z

Hey @jamesmunns , thanks for this! I think this is a great step forward.

I:

built your PR locally
wrote a new book in tree with two pages, linking to each other
built with mdbook1 and watched the linkcheck fail
built with mdbook2 and watched only print.html fail

I'm not sure about the license check mention, given that travis passed here. @ehuss could you say more about the problem you see here?

Given that both of us are still running into rust-lang/mdBook#828, here's what I'd like to propose:

I'm going to look into the print.html issue now
we let this PR sit over the weekend, I highly doubt that I'll have a bugfix ready in the remaining time I have today
Hopefully on Monday i'll have a patch and we can put out a new mdbook release, update this PR to include it, and then merge.

Sound like a plan?

Thanks again for working on this; I didn't realize that we could depend on both versions so easily!

ehuss · 2019-01-11T22:00:07Z

I'm not sure about the license check mention, given that travis passed here. @ehuss could you say more about the problem you see here?

Yea, the license checks are only performed in the distcheck builder, which is not run on PRs. I've wondered in the past if it might be possible to run a reduced job on PRs that only did license checks, but I'm not sure if distcheck is too different to get an accurate result quickly (distcheck requires generating a release tarball, extracting it, yadda yadda). It's a pain because nobody knows about the problem until bors tries to merge.

AFAIK, it can be run locally using the following steps:

Run cargo vendor
Edit config.toml and set vendor to true.
./x.py test tidy

After it's done, don't forget to delete .cargo/config and unset vendor and maybe delete the vendor directory.

License rules and exceptions are stored in https://github.com/rust-lang/rust/blob/master/src/tools/tidy/src/deps.rs.

steveklabnik · 2019-01-11T23:29:40Z

Ah ha, thanks. I wonder if that's something I forgot or something that's changed since last time I delt with this...

jamesmunns · 2019-01-14T03:06:30Z

Hey @steveklabnik, I didn't see this (my inbox is a mess right now), but your plan sounds good! I'll be available during Berlin business hours this week as well if I can help with anything.

If you are able to fix the print.html issues, I can also get the embedded book PR fixed up ASAP!

steveklabnik · 2019-01-14T15:44:22Z

It's all good!

So, between Friday and this morning, I think I've found the culprit. Bad news is, I'm not sure the fix will be easy. I'll fill in more details on the mdbook issue.

steveklabnik · 2019-01-15T20:27:50Z

Update: I have a patch in (rust-lang/mdBook#866) testing it locally now.

steveklabnik · 2019-01-15T21:09:32Z

Good news! Not only has my local test been successful, but I applied #56291 on top of it as well, and the tests seem to pass!

Next steps are to get rust-lang/mdBook#866 reviewed, a release cut, and update this PR to use it.

Thank you again for sticking through this, it's been a journey but I'm really excited about it. This "two versions of mdbook" strategy is going to work out much more nicely than my initial "oh god do the work of updating all of the books at the same time" thing I thought I had to do.

steveklabnik · 2019-01-18T15:45:29Z

@jamesmunns I have released mdbook 0.2.3 with the fix; can you update this PR to use that version, and then we can merge 🎊

jamesmunns · 2019-01-18T16:40:50Z

Sure! I'll try to get to this in the next 2-3 hours!

jamesmunns · 2019-01-19T04:17:32Z

@steveklabnik updated to use the new 0.2.3 release. @ehuss I have also added a license exception for arrayref.

jamesmunns · 2019-01-21T13:54:04Z

Hey @steveklabnik, reping on this for the r+ :)

🔒 Merge conflict

This pull request and the master branch diverged in a way that cannot be automatically merged. Please rebase on top of the latest master branch, and let the reviewer approve again.

How do I rebase?

Assuming self is your fork and upstream is this repository, you can resolve the conflict following these steps:

git checkout mdbook-compat (switch to your branch)
git fetch upstream master (retrieve the latest master)
git rebase upstream/master -p (rebase on top of it)
Follow the on-screen instruction to resolve conflicts (check git status if you got lost).
git push self mdbook-compat --force-with-lease (update this PR)

You may also read Git Rebasing to Resolve Conflicts by Drew Blessing for a short tutorial.

Please avoid the "Resolve conflicts" button on GitHub. It uses git merge instead of git rebase which makes the PR commit history more difficult to read.

Sometimes step 4 will complete without asking for resolution. This is usually due to difference between how Cargo.lock conflict is handled during merge and rebase. This is normal, and you should still perform step 5 to update this PR.
