Out of space behaviour can be improved

Tried running rustup.rs's installer with 200M limit on $HOME:

I think installer should check for free disk space and warn user before continuing.

P.S. Why the file is copied, not moved or linked BTW?

Related to #275

There's not a great reason these files are copied and not moved, though it's important that the installation code does not assume that the temporary directory is on the same mount point as the destination. I don't know offhand if there are gotchas moving files across mount points.

I just did a normal rustup update and it took me a while to figure out the error was due to not having enough free space, since the errors don't make mention of this. I tried it twice, and it failed slightly differently:

Note that both times the download calculation is corrupted: 43.4 MiB / 92 B (49453995 %) 6.0 MiB/s ETA: -7 s. Is this also due to no free space?

EDIT: Forgot to mention that after making space, everything upgrades fine:

Update on this, I keep getting even more unhelpful errors on the latest version: error: component download failed for rustc-x86_64-unknown-linux-gnu

[dbrgn]

Same issue here. I was confused for a while.

$ rustup update

Maybe the actual error when downloading fails should be analyzed?

Different but related problem for me. I just tried to install via rustup on a shared school computer with a 700mb/user quota. I didn't get any error messages at all: rustup appeared to download and install everything successfully. Uninstalling and reinstalling both rustup and the stable toolchain never produced any errors, however it appears that rustup ran out of space mid-install, as many files in ~/.rustup/toolchains/[target]/lib/rustlib/[target]/lib/ have zero size. This didn't manifest as a problem until I tried compiling something, at which point rustc simply reported that it couldn't find core.

I'm not sure exactly when in the installation it ran out, but hopefully the attached list of zero-size files in .../[target]/lib provides some indication?

I just run into a similar problem. (Or the same one still not handled.)
There seems to be a hint when unpacking fails because of full disk. But none when it happens while downloading:

I first thought I was having a bad connection and took a while to find the actual problem.

[suvayu]

I don't know if this is the right issue to report, but I get the exact same error, but I have plenty of space!

I was having this issue when I tried to update. Then I nuked everything under ~/.rustup and ~/.cargo to start afresh. But the fresh attempt also led to same issue.

I'm on Fedora, and my file system is btrfs, in case that matters.

$ uname -r

$ btrfs version

@suvayu I expect this "perhaps you ran out of disk space?" to appear just because of std::io::ErrorKind::StorageFull was not added when rustup was created, so it assumed any ErrorKind::Other (or just unhandled cases) mean "storage full".

Actual error is "Bad address (os error 14)" - not a typical error to come from a filesystem. Maybe you should check dmesg output for anything suspicious. Filesystem may be not in a good shape, you may want to check it.

[suvayu]

@vi Thanks, that helped. I have been having some stability problems on this machine. I was logged in remotely, Looks like there was a kernel panic. Rustup worked fine after I rebooted the system.

[iaverypadberg]

I ran into this issue recently while using the rustup default stable command on my coral devboard. dh -h showed that I had 2gb/7gb of free space. I've concluded that that is not enough space to make this work. Unfortunate but I guess the error was right.

[djc]

I think the behavior has probably improved quite a bit since this issue was filed (in 2016), so I'm going to close this. Please feel free to file new issues if run into a concrete situation where you think rustup can/should do better.
