With these commits, --show-progress will have a progress bar with an end point and an ETA. To do this accurately, the pv was moved outside of the calls to compressor and decompressor, and to compensate for the resultant jumps in transfer rate these commits use the -a flag to pv to show the average transfer rate. Also, build-remote was updated to CopyClosure::copyTo's new argument list.

Although I've not tested it, I'm for it!

This introduces a dependency on awk and is also a bit inefficient. The summation can also easily be done in Perl, e.g. (not tested)

use List::Util;
my $size = sum (split ' ', `nix-store -q --size @missing`);

It's also possible to prevent a call to nix-store by using the queryPathInfo() function in Perl.

Ok. I'll go back to the drawing board and resubmit this.

Don't log from inside the logger

This deadlocks ProgressBar, e.g.

  # nix run --impure --no-substitute --store '/tmp/nix2?store=/foo' --expr 'derivation { builder = /nix/store/zi90rxslsm4mlr46l2xws1rm94g7pk8p-busybox-1.31.1-x86_64-unknown-linux-musl/bin/busybox; }'

progress-bar.cc: fix signed overflow
ffbad9b 
this was caused by the use of std::chrono::duration::max() which gets
multiplied by some ratio to calculate nanoseconds to wait. then, it
explodes because that is a signed integer overflow. this was definitely
a bug.

error below:
