For instance it is conceivable that the pointed to file is replaced by a file with a new name, and then the symlink is dead. To handle this check specifically for all existing symlinks to be removed. (This bugged me for some time with a link libXvMCr600.so always being in the way of installing this file) v2: use only os.lexist and replace all instances of os.exist (Dylan Baker) v3: handle directory check correctly (Eric Engestrom) Fixes: f7f1b30f81e842db6057591470ce3cb6d4fb2795 ("meson: extend install_megadrivers script to handle symmlinking") Reviewed-by: Eric Engestrom (v2 minus dir check) Reviewed-by: Dylan Baker Signed-off-by: Gert Wollny --- diff --git a/bin/install_megadrivers.py b/bin/install_megadrivers.py index 8d9ed9c..551e385 100755 --- a/bin/install_megadrivers.py +++ b/bin/install_megadrivers.py @@ -43,13 +43,15 @@ def main(): master = os.path.join(to, os.path.basename(args.megadriver)) if not os.path.exists(to): + if os.path.lexists(to): + os.unlink(to) os.makedirs(to) shutil.copy(args.megadriver, master) for driver in args.drivers: abs_driver = os.path.join(to, driver) - if os.path.exists(abs_driver): + if os.path.lexists(abs_driver): os.unlink(abs_driver) print('installing {} to {}'.format(args.megadriver, abs_driver)) os.link(master, abs_driver) @@ -60,7 +62,7 @@ def main(): name, ext = os.path.splitext(driver) while ext != '.so': - if os.path.exists(name): + if os.path.lexists(name): os.unlink(name) os.symlink(driver, name) name, ext = os.path.splitext(name)
