# This file provides FindPackage() function which maps paths and
# commands, such as found in shell scripts, to rpm dependencies.
#
# Usage:
# . @RPMCONFIGDIR@/find-package
2007-08-08 00:49:48 +04:00
# FindPackage src [path...] [command...]
#
# Arguments:
# src - the file being processed, used for diagnostics;
# also, if the file appears to reside under */sbin/
# directory, the PATH search order is adjusted
# so as to better match root code
2007-08-08 00:49:48 +04:00
# path - absolute path to file, e.g. /bin/cat
# command - executable expected to reside under standard
# PATH directories, e.g. cat

# We use different PATHs for */sbin/ and non-/sbin scripts. However,
# the distinction is not quite reliable -- there is simply no easy way
# to discriminate between root-only and user-capable shell code. Thus
# we must use rather conservative path adjustment: 1) the set of user
# and root directories is the same, it is only the order that differs;
# 2) / has main priority over /usr, while as "bin vs sbin" distinction has
# only secondary priority. The reason is that / has only "most important"
# contents, and /usr is used virtually "for everything else", whatever it is.
# Now that / has a boost, there are simply less chances to end up with
# unrelated dependencies.

find-package (FindByName): optimized awk script It looks like that, unlike in perl, pattern matching in awk is very slow. Perhaps they just don't have regexp engine hackers like Larry Wall or Ilya Zakharevich (or, most recently, Yves Orton aka demerphq). That's okay, since I can rewrite the script without pattern matching at all. That is, I don't have to split each index line into dir+basename, because I can prepare all valid absolute pathnames in advance.
