Bug 886017 – app-alternatives/{awk,bc,bzip2,cpio,gzip,lex,sh,tar,yacc}: stabilisation

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sam James 2022-12-15 05:33:11 UTC]

Filing in preparation so we do it all in sync.

[Comment 1 Sam James 2022-12-15 05:37:44 UTC]

I've included some first-time stabliisations here so we don't have to package.use.stable.mask in a bunch of places and most of these are pretty useful tools. It'll be nice for users to have more choice on various platforms.

[Comment 2 Sam James 2022-12-15 06:10:56 UTC]

I've added some detail for users & developers at https://wiki.gentoo.org/wiki/Project:Base/Alternatives.

    profiles/base: add app-alternatives/{awk,bzip2,gzip,sh,tar} to @system
    
    - Before this commit, nothing pulls in app-alternatives/sh, so we're relying on
      app-shells/bash handling /bin/sh as an orphaned symlink (which is one of the big
      things we're trying to move away from).
    
    - Add in the others (app-alternatives/{awk,bzip2,gzip,tar}) to allow setup
      via /etc/portage/package.use without adding these to @world manually,
      this also lays the ground work for at some point removing specific implementations
      in the future (after making sure ebuilds which need specific impls. depend on them).
    
    - Note that there's two exceptions:
      1. app-alternatives/yacc
    
         No need to explicitly add into @system, because we previously had virtual/yacc
         so it'll get pulled in by ebuild dependencies anyway.
    
      2. app-alternatives/lex
    
         We never had virtual/lex before and packages very often explicitly
         depend on sys-devel/flex. But this isn't a big deal given it's very unlikely
         that a user wants to try modify lex yet and reflex is still very new as an
         option in Gentoo.
    
         That is, as time goes on and we test more to ensure it works with any lex,
         it'll get pulled in as various ebuilds get updated anyway.
    
    - We keep app-arch/bzip2 & app-arch/gzip in @system for now because PMS
      is clear they must be available and I'd rather be conservative for now,
      as we want to get the change in this commit in to minimise disruption
      wrt the app-alternatives migration, but I'd like to revisit this another
      time.

    Re-implement get_bootparam as pure sh, eliminating the gawk dependency
    
    The current implementation of get_bootparam() specifically invokes gawk
    and has some deficiencies, such as failing to inhibit pathname
    expansion and not breaking the loop once a match has been made.
    
    In fact, the problem can be solved using sh(1) alone, and the revised
    function does precisely that. Note that the definition of the function
    is now the kind of compound command that incurs a subshell. Hence, one
    subshell is incurred for the entire routine and there is no compelling
    reason to use the (non-standard) local keyword, nor be concerned with
    the consequences of disabling pathname expansion.
