[tlbuild] tlmgr/install-tl bug: running out of disk space

[Norbert Preining]

Hi Johannes,

thanks for testing!!

> 1. I like, in principle, that install-tl is complaining that disk space

You used the text installer, right? With that you should have seen a
HUGE warning just above this line:
> 
> Enter command: I

*** WARNING ****************************************************
The installation requires $vars{'total_size'}M of disk space
but only $vars{'free_size'}M is available.

You probably want to either clean up the destination filesystem,
or choose a different installation location,
or reduce what gets installed.

Press Enter to return to the menu, or i to install anyway.
****************************************************************

> Installing [1/4, time/total: ??:??/??:??]: hyphen-base [22k]
> Insufficient disk space, but continuing anyway.Installing [2/4, time/total: 00:00/00:00]: kpathsea [1087k]

The warning here is going to STDERR and thus is shown so strange.
I will simply disable it, I guess there is no need for it.

That is **absolutely** unbelievable, since there is no single line
dependent on the actual mirror. I guess it is a timing issue, that is,
the Ctrl-C is received while the tar is running or while the perl code
is running. I thought the signal handler would deal with that ... though
...

Nothing I/we can do about it.

No idea ..

> When the disk ran out of space again, install-tl throws the same error

Yes, that is as expected. You got above big fat warning and agreed to
continue. We don't do anything more, mostly because *actual* free space
and the one reported by "df" might not agree (COW file systems).

And read the warning ....

Best
