Package file listing and reverse lookup

[lgritz]

It would be great to have a command like spk manifest opencolorio that would list all of the individual things installed by the package layer (and optionally a flag to recurse and show you what would be supplied by all its runtime dependencies).

Also spk which maketx or spk which libIlmImf.so or spk which half.h should do the reverse searches, telling you what package would be needed in order to get a particular installed component that you need. (I'm not sure what the right name of this command should be, "which" is just my placeholder until somebody smarter chimes in.)

[rydrman]

in many other managers that's something like spk provides libIlmImf.so

I'm not sure what you mean by manifest - like to get the list of files?

[lgritz]

provides -- yeah, that's the idea.

manifest is the inverse -- what are all the files it provides

From the meeting today:

• three cases:
  1. which package is providing a given file from spfs spk which /spfs/path/to/file
  2. what packages in the repo provide a specific file path or name spk provides /spfs/path/to/file
  3. what files are contained within a package spk info --manifest/--files <package>
  4. list files in the current spfs, with which package it came from spk ls [OPTIONAL_REQUESTS] -- <path>
  5. bonus if it can show shadowed providers
• @dansheerin how can we make sure that we get this information from someone else's environment
  • @rydrman you would need something like the spfs digest as part of the error message
  • @dansheerin maybe some way to map/filter paths in a stream (like stack trace output)

It would be cool for spk search to have a way to search for files with a glob pattern. It seems natural to put this in the "search" tool but if the proposed spk provides can take a glob pattern then that's okay.

The spk which case was effectively implemented by #690.
