Submodule public_finance_2018_2019 is broken

[mthused]

Looks like the public_finance_2018_2019 repository has disappeared from github...

[johnperry-math]

The dask-tutorial repository has also deleted its master branch. I can't get index.py to run correctly. Anyone have any advice on how to make this work?

Wow, the subtle side effects of political correctness...

Can you just change our code from master to main...?

Are you serious? I have a master branch and it works. I should add that I'm not 100% sure it lacks a master, but running index.py failed with a complaint about that. There are at least a couple of others like that, too: math157 and the scikit-image-examples or something like that.

I made it work once by disabling a bunch of repositories. Right now it looks as if I will have to clone, but not recursively, on account of public_finance_2018_2019, remove its submodule, etc. I'll try to change the branch, then if I can get everything working I'll submit a pull request.

Are you serious?

Yes. There is a movement to rename terms that some find offensive in software engineering, including "master", "slave", "white list", "black list", etc. Some real thought [1] has gone into which terms are offensive, and what better terminology is recommended and a huge chunk of the industry has made changes as a result. It's important to be aware of, so you can understand why a repo would seemingly randomly delete their master branch...

Thanks!!

Well, I've known about that for something like 20 years, when I think a San Francisco clerk (?) sent a letter to a supplier demanding that they change the names of "master-slave". But "master" in git has a different meaning; there are no slaves involved, and "master" in general descends from the Latin word for "teacher", and still has that meaning in many contexts.

I don't mean to sound quarrelsome, and apologize if I do. I'm just trying to explain my surprise.

Thanks!!

I'll also post (hopefully correct) directions in a followup.

Here's what I did to generate Pull Request [insert here, moron!], in case other people need to do this before it gets fixed.

1. fork it in GitHub
2. git clone my fork's repository
3. cd cocalc-examples
4. edited index.yaml:
   a. as per usual instructions to add a repository
   b. commented out public_finance_2018_2019 because it no longer exists on GitHub
   c. also commented out first-steps because it no longer exists in the cocalc-first-examples repository
5. git submodule add the submodule I wanted to add
6. git submodule update --init --recursive
7. Wait a while. Don't panic when you see the error message on public_finance...
8. git submodule deinit -f -- public_finance_2018_2019
9. git rm public_finance_2018_2019
10. git pull --recurse-submodules this is important
11. Someone broke the think-complexity-2ed submodule by deleting a bunch of stuff (!?!?!) so you have to fix it:
    a. cd think-complexity-2ed
    b. git reset to fix it
    c. git stash to sort-of get rid of the deletions
    d. cd ..
12. Repeat step 11 for think-stats
13. Repeat step 11 for think-bayes
14. Repeat step 11 for nbgrader-demo
15. Now run ./index.py.

Simple, right? ;-)

Eek, let me add something I forgot to mention. When I run git status, I get the following:

$ git status

no changes added to commit (use "git add" and/or "git commit -a")

If I run git diff, I see:

$ git diff

[lots more like the above]

I'm not versed enough in git to know if this should concern me, but I think it shouldn't. I tried adding them, but no dice. I'm not sure how to interpret that. Let me know if it should concern me.

You need to do

git commit -av
git push

[johnperry-math]

Doesn't help:

git commit -av

I'll dig deeper & report back.

[johnperry-math]

OK, that was quick. Descending into each folder I see that they also had someone/something attempt to delete everything in them, much the same as I had with other subfolders. I'm not sure how this happened, but git stash seems to succeed at restoring their status.

[johnperry-math]

One exception remains, and it's bizarre, possibly related to MacOS' file system. The submodule martinthoma-latex-examples has an issue with two files, publications/hasy/symbols/ae.pdf and publications/hasy/symbols/o.pdf. Whatever I do, whether a git stash or a git restore or rebase or whatever, git status keeps switching me between ae.pdf and AE.pdf and similarly for the o.

[johnperry-math]

I think I've fixed it. New pull request available.
