@ahgamut Can we remove rsync from Cosmos? This isn't something I'm willing to support on Windows.

[endgame]

I'm a bit surprised; I'd hoped cosmos rsync would be a good answer when @wezm was looking for a windows rsync in another chat that I'm in.

@jart Is it just not supportable on windows due to some kind of blocker?

[ahgamut]

If expected behavior is obtainable, my guess is that we can patch some code in rsync to do so.
But we'd need a bit of testing: I haven't found a nice way to test/debug builds of rsync like I can for gcc or python.

Here's are some ways you can help us with that:

• what does the --strace for the same command look like on Linux?
• Is rsync relying on some filesystem locations to decide what to do? The above log shows /etc/passwd and /etc/group don't exist on Windows, perhaps the rsync code needs to be patched to not rely on such locations. (For reference, you can see that rsync picks the OpenSSL config from the correct location /zip/openssl.cnf -- that's because I configured it to do so.)

[jart]

Cosmos is a proof of concept we built for fun. If rsync isn't working due to an issue with cosmo, then I'd be happy to accept a patch that fixes it. However I don't want there to be any expectation that it's a tool we have the resources to support. rsync can't be easily troubleshooted, because its invocation is controlled by other tools, and every Windows administrator uses different tools.

[wezm]

Looks like it's going to be removed but in the name of completeness I'll answer this query:

• what does the --strace for the same command look like on Linux?

Run on x86_64 Linux:
