Consider the following example
bundle agent createfolder { files: "/home/nicolas/foo/." create => "true", comment => "Creating directory", classes => if_else("foldercreated", "failure"); commands: foldercreated:: "/bin/echo \"Folder created or present\""; failure:: "/bin/echo \"Failure\""; } body classes if_else(if, else) { promise_repaired => {"foldercreated"}; promise_kept => {"foldercreated"}; repair_failed => {"$(else)"}; } It should create the folder foo if it doesn't exist, and set the class foldercreated. But it doesn't (latest trunk build and cf3.0.2) Output if folder doesn't exist : cf3 Verifying SQL table promises is only available with Cfengine Nova or above cf3 cf3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . cf3 Skipping whole next promise (/bin/echo "Folder created or present"), as context foldercreated is not relevant cf3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . cf3 cf3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . cf3 Skipping whole next promise (/bin/echo "Failure"), as context failure is not relevant cf3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . cf3 cf3 ========================================================= cf3 files in bundle createfolder (1) cf3 ========================================================= cf3 cf3 Verifying SQL table promises is only available with Cfengine Nova or above cf3 cf3 ......................................................... cf3 Promise handle: cf3 Promise made by: /home/nicolas/foo/. cf3 cf3 Comment: Creating directory cf3 ......................................................... cf3 cf3 -> Using literal pathtype for /home/nicolas/foo/. cf3 cf3 + Private classes augmented: cf3 cf3 - Private classes diminished: cf3 cf3 cf3 cf3 ========================================================= cf3 commands in bundle createfolder (2) cf3 ========================================================= cf3 cf3 Verifying SQL table promises is only available with Cfengine Nova or above cf3 cf3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . cf3 Skipping whole next promise (/bin/echo "Folder created or present"), as context foldercreated is not relevant cf3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . cf3 cf3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . cf3 Skipping whole next promise (/bin/echo "Failure"), as context failure is not relevant cf3 . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Using "/home/nicolas/foo/" as a temporary workaround: it failed for it is not a file, but a folder, and at the next iteration the folder is there, so the promise is kept Regards, Nicolas _______________________________________________ Bug-cfengine mailing list Bug-cfengine@... https://cfengine.org/mailman/listinfo/bug-cfengine |
