In our meson scripts, we use configure_file(copy:true) to copy
files from srcdir into builddir. However, as of meson-0.64.0,
this is deprecated [1] in favor of using:
fs = import('fs')
fs.copyfile(in, out)
Except, the submodule's new method wasn't introduced until
0.64.0. And since we can't bump the minimal meson version we
require, we have to work with both: new and old versions.
Now, the fun part: fs.copyfile() is not a drop in replacement as
it returns different type (a custom_target object). This is
incompatible with places where we store the configure_file()
retval in a variable to process it further.
While we could just replace 'copy:true' with a dummy
'configuration:...' (say 'configuration: configmake_conf') we
Actually, it would be even more clear that it is a dummy configuration if you used a dict instead of cfg_data. Meson allows this in configure_file() according to the docs: https://mesonbuild.com/Reference-manual_functions.html#configure_file
can't do that for binary files (like src/fonts/ or src/images/). Therefore, places where we are not interested in the retval can be switched to fs.copyfile() and places where we are interested in the retval will just use a dummy 'configuration:'. Except, src/network/meson.build. In here we not just copy the file but also specify alternative install dir and that's not something that fs.copyfile() can handle. Yet, using 'copy: true' is viewed wrong [2]. 1: https://mesonbuild.com/Release-notes-for-0-64-0.html#fscopyfile-to-replace-configure_filecopy-true 2: https://github.com/mesonbuild/meson/pull/10042 Signed-off-by: Michal Privoznik <mprivozn@xxxxxxxxxx> --- docs/css/meson.build | 6 +++++- docs/fonts/meson.build | 6 +++++- docs/images/meson.build | 6 +++++- docs/js/meson.build | 8 ++++++-- docs/logos/meson.build | 6 +++++- docs/meson.build | 6 +++++- meson.build | 3 +++ src/locking/meson.build | 8 ++++---- src/network/meson.build | 2 +- 9 files changed, 39 insertions(+), 12 deletions(-) diff --git a/docs/css/meson.build b/docs/css/meson.build index 384f6e789f..a2a2ccfb28 100644 --- a/docs/css/meson.build +++ b/docs/css/meson.build @@ -11,7 +11,11 @@ install_data(docs_css_files, install_dir: docs_html_dir / 'css') foreach file : docs_css_files # This hack enables us to view the web pages # from within the uninstalled build tree -

As mentioned above I'd just use:
configuration: {},
here instead, but honestly, I haven't tried it.
