bug#22693: `guix refresh -u` updates other packages with same version

[Leo Famulari]

I've noticed that `guix refresh -u` will update extraneous packages if
they happen to have the same version and be in the same module.

For example, from commit d694230ab, you can reproduce the bug:

I wondered about the "./pre-inst-env guix environment guix", but I tried it
without, and I confirm the problem.

I like to offer my bug reports with './pre-inst-env' and a commit, to
increase the number of factors that are deterministic.

How to fix this?

The procedure is ‘update-package-source’ in (guix upstream).
it find the file, then use ‘substitute’ to replace the version and
hash.  ‘substitute’ works line-by-line, it can’t match mutiple lines.

I try:
 - use ‘package-location’ and ‘read’ to get the package object,
   but it lost all format and comments.
 - use ‘string-match’, but I have no idea how to match the whole
   package sexp.

fixed in commit 2b8e9d9ed.

One option:

  1. open the source file for the package
  2. Call (read) until port-line / port-column are beyond the
     package-location of the package
  3. At that point you have the ending location of the package.

Then limit your substitute* to work within those lines.

Another option would be to extend substitute* to start on a certain
line, and to limit the number of substitutions.  That way if you start
on package-location and limit to one substitution you are likely to
update the correct version.

Right.  ‘package-field-location’ does something along these lines.

A simpler yet less elegant trick used in ‘report-formatting-issues’ in
(guix scripts lint) is to have a maximum number of lines assumed to be
part of the ‘package’ form following its starting line.

Thanks,
