From: Dmitry Gutov Date: Fri, 9 Dec 2022 16:15:49 +0000 (+0200) Subject: Bring back the project--value-in-dir logic X-Git-Tag: emacs-29.0.90~1278^2 X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=d268ab1c5d749d0f15474f9d200bc0356ad85765;p=emacs.git Bring back the project--value-in-dir logic Essentialy revert commit 2389158a31b4a12, restoring the changes and fixing the conflicts. Motivated by the problem brought up in bug#59722 (behavior of project-find-files/regexp when switching projects). We should find other ways to improve performance. * lisp/progmodes/project.el (project--value-in-dir, project--vc-merge-submodules-p): Restore. (project-try-vc, project-files, project--vc-list-files) (project-ignores, project-buffers): Use. * test/lisp/progmodes/project-tests.el (project-vc-supports-project-in-different-dir): New test. * test/lisp/progmodes/project-resources/.dir-locals.el: * test/lisp/progmodes/project-resources/foo: * test/lisp/progmodes/project-resources/etc: New files. --- diff --git a/lisp/progmodes/project.el b/lisp/progmodes/project.el index 38d4fdad5fc..342ee239c7e 100644 --- a/lisp/progmodes/project.el +++ b/lisp/progmodes/project.el @@ -515,7 +515,8 @@ project backend implementation of `project-external-roots'.")
