Subject: "guix package -i" exception should be a normal error message
Date: Tue, 14 Feb 2017 09:41:06 +0100

When I have network problems sometimes I get a backtrace like this:

...
substitute: 1727: 3 [%start-stack load-stack #<procedure a97d60 at ice-9/boot-9.scm:4047:10 ()>]
substitute: 1732: 2 [#<procedure a99b70 ()>]
substitute: In unknown file:
substitute:    ?: 1 [primitive-load "/gnu/store/175nlv448nk5kagwwl3zyy2w4726qfz6-guix-0.12.0-4.d9da/bin/.guix-real"]
substitute: In guix/ui.scm:
substitute: 1228: 0 [run-guix-command substitute "--query"]
substitute: 
substitute: guix/ui.scm:1228:8: In procedure run-guix-command:
substitute: guix/ui.scm:1228:8: Throw to key `bad-response' with args `("Bad Response-Line: ~s" (""))'.

It might make sense to

(a) convert that into a normal runtime error message and
(b) Fallback to substituteless building (maybe only for this thing).

Hi Danny,

This old bug #25719 is about exception and error message.  See:

What do you mean?

Is it not the case currently?


All the best,

I haven't seen this particular exception in a long time.  I cannot tell whether
the actual usability has been fixed, though--it could be that only the servers
are more reliable and this code path is thus not currently being entered.

The above is an exception.

In this case the download failed--and unfortunately that is a completely normal
thing on the internet.  Therefore, that is not something you'd use an exception
for.

There is no added information that could help the user in the exception.
For example it doesn't list the URL--the one thing that would actually help.

No, I'm pretty sure I had to manually specify "--fallback" like a week ago--otherwise
it would not fallback to building without substitutes, but it would just fail.

If I understand correctly, instead of the backtrace you would like a
message captured by the exception, right?

All the best,

Therefore, I am in favor to close it.  And maybe reopen it or open
another one it happens again.  WDYT?
