'optimize install_complementary' really doesn't match what the commit contains, please be more specific.

Hi Alex Would a better headline be "don't handle empty glob" Also a small question. Looking at the getVar code - It seems that it can return None in some specific situations. So it might be more clear to do if globs is None or globs == "": return The optimizing part is that the install_complementary normally does. if globs is None: globs = "" if globs is None: return do work, where if glob is empty string, it does not matter. (Involve creating installed_pkgs file, and process it with oe-pkgdata- util but with empty glob, so it will never return anything, just spend time on each line in the file, and create a empty list of packages, where it will call install of those) So the change optimize by removing the work on an empty string. What is your take. Do you like "don't handle empty glob" as headline, and what do you prefer if globs is None or globs == "": return vs if not globs: return /Claus On Thu, 2024-09-26 at 11:51 +0200, Alexander Kanavin wrote: > 'optimize install_complementary' really doesn't match what the commit > contains, please be more specific. > > Alex > > On Thu, 26 Sept 2024 at 11:17, Claus Stovgaard via > lists.openembedded.org > <claus.stovgaard=gmail.com@lists.openembedded.org> wrote: > > > > We are rewriting the globs variable, so it can't be None, but > > rather a > > string.

Hello, the headline should be 'return early from install_complementary if glob is either None or an empty string'. I prefer a shorter condition.

We are rewriting the globs variable, so it can't be None, but rather a string. E.g. the lines above. if globs is None: globs = self.d.getVar('IMAGE_INSTALL_COMPLEMENTARY') As globs is now a string, we need to test for empty string instead of compare with None.
