[Bug 486716] Re: Can't search database if a command is on PATH

[Dominique Ramaekers]

It seems this function never got to the ubuntu-core-dev code.

On issuing:

$ /usr/lib/command--not-found --help

The c-n-f gives a help message with a clear description of how to use
--ignore-installed.

It's a pity of Zygmunts work but it seems nobody really misses the
'easier' way.

For the 'x86_64 crash', I think in version 0.3, it's not an issue.

I'm changing the status in won't fix...

** Changed in: command-not-found
       Status: Confirmed => Won't Fix

** Changed in: command-not-found (Ubuntu)
       Status: Confirmed => Invalid

Title:
  Can't search database if a command is on PATH

Status in command-not-found:
  Won't Fix
Status in command-not-found package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: command-not-found

  If a command is already installed by some package, there's no way to
  search command-not-found's database (short of some sort of PATH hack).
  Searching the database would be a handy way to find out what package
  provides that command, along with what other packages provide
  identically-named commands.  It's also possible to do some of that
  using dpkg -S, but that only works if the command *is* installed by
  some package, and it uses a different database, and it doesn't list
  other packages that provide identically-named commands, and it's slow.

  The attached patch adds a new command "packages-providing" that prints
  a two-column list listing package names and components that provide
  the named command -- e.g.:

  $ packages-providing alien
  alien main

  The patch also changes one line of code to not crash on x86_64
  architecture.

  This isn't yet properly tested, since I found the database building
  code seems broken: is that a known issue?  I tested as far as hacking
  the code a bit to get myself a tiny database, building and installing
  the package, and seeing that "packages-providing alien" printed what I
  expected.  Can I get a pre-built database that's compatible with bzr
  command-not-found from somewhere?

  Patch is against bzr revision 71.
