mk/subst.mk: Unbreak builds with no substitutions. At least some implementations of rmdir(1) do not allow you to remove the current working directory. Fixes bootstrap on SunOS.

# $NetBSD: subst.mk,v 1.72 2020/03/23 11:27:29 jperkin Exp $
subst.mk is a Makefile fragment that implements a general text replacement facility for different classes of files in ${WRKSRC}. For each class of files, a target <class>-subst is created to perform the text replacement. The following variables are used: SUBST_STAGE.<class> "stage" at which we do the text replacement, e.g. pre-configure, post-build, etc. SUBST_MESSAGE.<class> message to display, noting what is being substituted SUBST_FILES.<class> files on which to run the substitution; these are relative to ${WRKSRC} SUBST_SED.<class> sed(1) substitution expression to run on the specified files This basically extracts a useful piece of code from bsd.buildlink2.mk and puts it in a place that allows it to be more widely used, and so that the functionality doesn't depend on USE_BUILDLINK2 being defined.

mk/subst.mk: use simpler words in the documentation, add an example
2019-04-28 14:31:15 +02:00
# The subst framework replaces text in one or more files in the WRKSRC
# directory. Packages can define several ``classes'' of replacements.
# Each such class defines:
#
# - in which stage of the build process the replacement happens
# - which files are affected by the replacement
# - which text or pattern is replaced by which replacement text
#
# A typical example is:
#
# SUBST_CLASSES+= prefix
# SUBST_STAGE.prefix= pre-configure
# SUBST_FILES.prefix= ./configure doc/*.html
# SUBST_SED.prefix= -e 's,/usr/local,${PREFIX},g'

# SUBST_MESSAGE.<class>
If the package doesn't provide a SUBST_MESSAGE, generate a default one. This way, file modifications cannot go unnoticed and at least appear in the build logs. While here, fixed an ambiguity in the description of SUBST_MESSAGE.

# The message to display before doing the substitution.
Usually there's no need to keep the original version of a file "foo" as "foo.subst.sav". Implement SUBST_POSTCMD, which by default cleans up these leftovers. If you need to keep them around, e.g. while debugging, set it to ${DO_NADA}. Remove superfluous whitespace in a comment.

Fixed subst.mk not to corrupt files Up to now, using subst.mk may have led to file corruption during active package development. This happened when a sed(1) command had a syntax error, in which case the whole sed(1) command was terminated, leaving an empty original file behind. This commit changes that behavior by applying the sed(1) commands to the original file and saving the result in a temporary file. Only after that succeeded is the original file overwritten. During this rewrite, SUBST_POSTCMD has been removed, since it was only used in one place (mk/wrapper), and since it relied on the exact sequence of the internal commands. No package in either main pkgsrc or pkgsrc-wip uses this variable right now.

Most of them were just outdated, which is no surprise given that some packages are already over 20 years old. For backwards compatibility, SUBST_NOOP_OK defaults to "yes" right now.

Then they will all be reported as warnings, followed by the final error saying that the pattern has no effect. This change makes it easier to detect inconsistencies and outdated definitions, for example by setting the global SUBST_NOOP_OK=no and redefining WARNING_MSG to actuall fail.
