Unable to parse Git repositories with `insteadOf` and `pushInsteadOf` URI "rewrites"

[hyperupcall]

Hello!

With the following remote configuration:

$ git remote -v
me git@github.com:reconquest/shdoc (fetch)
me git@github.com:reconquest/shdoc (push)

Clicking the "View Repository" button yields https://reconquest/shdoc - I expected it to redirecredirect to https://github.com/reconquest/shdoc.

With the following remote configuration:

#!/usr/bin/env sh
git init

# GitHub allows for re-writing remote URls on the fly with 'insteadOf' and 'pushInsteadOf' fields.
# This is what trips up vscord. Normally, these are globally configured.
git config --local --add url.'git@github.com:'.insteadOf 'gh:'
git config --local --add url.'git@github.com:'.pushInsteadOf 'gh:'
git remote add me gh:fox-projects/repro-vscode-weird-url

# vscord seems to require a "minimum git history" for showing the "View Repository" button.
# This sets that up.
touch file.txt && git add file.txt && git commit --no-edit --no-template --allow-empty-message
git commit --no-edit --no-template --allow-empty --allow-empty-message

$ git remote -v
me      git@github.com:fox-projects/repro-vscode-weird-url (fetch)
me      git@github.com:fox-projects/repro-vscode-weird-url (push)
$ cat .git/config
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[url "git@github.com:"]
        insteadOf = gh:
        pushInsteadOf = gh:
[remote "me"]
        url = gh:fox-projects/repro-vscode-weird-url
        fetch = +refs/heads/*:refs/remotes/me/*

It seems that there is a parsing error when parsing the value of remote.me.url. You might useful a similar issue/fix I made at xournalpp/xournalpp.

Clicking the "View Repository" button yields https://fox-projects/repro-vscode-weird-url - I expected it to redirect to https://github.com/fox-projects/repro-vscode-weird-url.

Hey @hyperupcall,
Going to need some more information. What is the me in the git remote. I have never seen this before. When I ssh clone the repo git clone git@github.com:reconquest/shdoc.git
When I do git remote -v I get back this and my view repository button works

origin  git@github.com:reconquest/shdoc.git (fetch)
origin  git@github.com:reconquest/shdoc.git (push)

[hyperupcall]

I use me instead of origin - it seems the issue was that I am using a non-standard default-remote name, and not that the remote URL is not SSH-style?

[nick22985]

Also looking at this it seems to work for me when using me for the git remote

 ╰─λ git remote -v
me      git@github.com:reconquest/shdoc (fetch)
me      git@github.com:reconquest/shdoc (push)

[hyperupcall]

Interesting - this definitely isn't the first time I have come across this issue, but I am suddently unable to reproduce. I'll see if I can find a better repro.

Okay so I found an actual repro:

#!/usr/bin/env sh
git init

# GitHub allows for re-writing remote URls on the fly with 'insteadOf' and 'pushInsteadOf' fields.
# This is what trips up vscord. Normally, these are globally configured.
git config --local --add url.'git@github.com:'.insteadOf 'gh:'
git config --local --add url.'git@github.com:'.pushInsteadOf 'gh:'
git remote add me gh:fox-projects/repro-vscode-weird-url

# vscord seems to require a "minimum git history" for showing the "View Repository" button.
# This sets that up.
touch file.txt && git add file.txt && git commit --no-edit --no-template --allow-empty-message
git commit --no-edit --no-template --allow-empty --allow-empty-message

$ git remote -v
me      git@github.com:fox-projects/repro-vscode-weird-url (fetch)
me      git@github.com:fox-projects/repro-vscode-weird-url (push)
$ cat .git/config
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[url "git@github.com:"]
        insteadOf = gh:
        pushInsteadOf = gh:
[remote "me"]
        url = gh:fox-projects/repro-vscode-weird-url
        fetch = +refs/heads/*:refs/remotes/me/*

It seems that there is a parsing error when parsing the value of remote.me.url. You might useful a similar issue/fix I made at xournalpp/xournalpp.
