Subject: [PATCH v2 0/3] Makefile: fix issues with bin-wrappers/% rule
Date: Wed, 26 Oct 2022 16:42:34 +0200 [thread overview]
Message-ID: <cover-v2-0.3-00000000000-20221026T143533Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-0.5-00000000000-20220901T130817Z-avarab@gmail.com>
This simple topic fixes issues with the bin-wrappers/% rules, as seen
in the range-diff below this never worked properly:
make bin-wrappers/git
I.e. we'd make the scirpt, but not "git".
I originally sent this as [1] in response to a topic that's since
landed, i.e. that topic needed to add more conditions to the "match
this, but not that" part of the current rule.
As 3/3 notes that's because we were previously squashing 3 Makefile
variables into one, and then having to heurisitcally match their
contents to figure out which item originally came from which variable.
The 3/3 here simply avoids squashing all that data together, so we
don't need to guess after the fact.
For the v2 I squashed the previous 3 commits together, they were
incrementally improving the rule, now we do it all at once.

Makefile: factor sed-powered '#!/bin/sh' munging into a variable

@@ Commit message
Which will show an empty diff, i.e. we've correctly dealt with the
combination of $(SHELL_PATH), $(X) and these three variables here.
+ This also fixes an issue with the "bin-wrappers/" scripts have never had properly declared
+ dependency information, i.e. this has never worked:
+
+ make clean &&
+ make bin-wrappers/git &&
+ # the script is there, but no "./git" is built
+ ./bin-wrappers/git
+
+ There was no reason not to have that work, just as most things
+ generated by the Makefile have proper dependency information.
+
+ Before this commit doing this would have been painful, but now it's
+ easy to pass this as a parameter to our "bin_wrappers_template"
