meson: use /bin/bash for script It seems -o pipefail does not work on Ubunut. /bin/sh is most likely resolved to dash. 2018-12-21 09:09:23 +03:00			`#!/bin/bash`

This change creates an overhead for "noop" builds. On my laptop, 'ninja -C build' that does nothing goes from 0.1 to 0.5 s. It would be nice to avoid this, but I think that <1 s is still acceptable. Fixes #7183. PACKAGE_VERSION is renamed to GIT_VERSION, to make it obvious that this is the more dynamically changing version string. Why save to a file? It would be easy to generate the version tag using run_command(), but we want to go through a file so that stuff gets rebuilt when this file changes. If we just defined an variable in meson, ninja wouldn't know it needs to rebuild things. 2018-12-20 22:35:25 +03:00

meson: allow setting the version string during configuration This will be useful when building distro packages, because we can set the version string to the rpm/dpkg/whatever version string, and getter reports from end users. 2018-12-19 15:33:09 +03:00			`tag="$2"`

scripts: use 4 space indentation We had all kinds of indentation: 2 sp, 3 sp, 4 sp, 8 sp, and mixed. 4 sp was the most common, in particular the majority of scripts under test/ used that. Let's standarize on 4 sp, because many commandlines are long and there's a lot of nesting, and with 8sp indentation less stuff fits. 4 sp also seems to be the default indentation, so this will make it less likely that people will mess up if they don't load the editor config. (I think people often use vi, and vi has no support to load project-wide configuration automatically. We distribute a .vimrc file, but it is not loaded by default, and even the instructions in it seem to discourage its use for security reasons.) Also remove the few vim config lines that were left. We should either have them on all files, or none. Also remove some strange stuff like '#!/bin/env bash', yikes. 2019-04-04 15:10:42 +03:00			`echo "$tag"`
