Forum: CFEngine Help Subject: Reuse edit_line Author: sandro...@gmail.com Link to topic: https://cfengine.com/forum/read.php?3,25568,25568#msg-25568
Hi, it's my first question in this forum, I've been searching around the web and in this forum for a similar question, but I couldn't find any related questions. I'm using a implementation of edit_line set_variable_values, found this one more recently: https://github.com/zzamboni/cfengine-copbl/blob/master/cfengine_stdlib.cf#L170 So I have two promises that uses the same bundle edit_line (i renamed set_values), the problem is that i have the same values in one file that I have in another, when i remove those repeated values from the second promises to be executed, nothing happens, only repair the file if I remove a value that its distinct from the another one, e.g.: file01.conf user=root password=default file02.conf user=root password=default engine=MyISAM In the example above, if I remove engine from file02.conf, it will be repaired, if I remove user=root from file02.conf, promise is kept. Can I reuse edit_line set_values multiple times from different promises in this case? Here's a sample code: bundle agent config_mybkp { vars: "mybackup_file" string => "/path/mybackup.conf"; "mycatalog_file" string => "/path/mycatalog.conf"; # mybackup.conf config values "mybackup" string => "default_schema"; "mybackup" string => "localhost"; "mybackup" string => "mysql"; "mybackup" string => "1000"; "mybackup" string => "20"; "mybackup" string => "root"; "mybackup" string => "default"; # mycatalog.conf config values "mycatalog" string => "default_schema"; "mycatalog" string => "localhost"; "mycatalog" string => "MyISAM"; "mycatalog" string => "30"; "mycatalog" string => "root"; "mycatalog" string => "default"; files: "$(config_mybkp.mycatalog_file)" perms => change_owner("0600","root","root"), create => "true", edit_line => set_values("config_mybkp.mycatalog"); "$(config_mybkp.mybackup_file)" perms => change_owner("0600","root","root"), create => "true", edit_line => set_values("config_mybkp.mybackup"); } bundle edit_line set_values(v) # Sets the RHS of configuration items in the file of the form # LHS = RHS # If the line is commented out with #, it gets uncommented and set to # the correct value. # Adds a new line if none exists. # To use: # 1) Define an array, where the keys are the LHS and the values are the RHS # "stuff" string => "rhs1"; # "stuff" string => "rhs2"; # 2) The parameter passed to the edit_line promise is the fully qualified # name of the array (i.e., "bundlename.stuff") WITHOUT any "$" or "@" { vars: "index" slist => getindices("$(v)"); # Be careful if the index string contains funny chars "cindex[$(index)]" string => canonify("$(index)"); replace_patterns: # If the line is there, maybe commented out, uncomment and replace with # the correct value "^[\s#]*$(index)\s*=.*$" replace_with => value("$(index)=$($(v)[$(index)])"), classes => always("replace_attempted_$(cindex[$(index)])"); insert_lines: "$(index)=$($(v)[$(index)])" ifvarclass => "replace_attempted_$(cindex[$(index)])"; } In the real scenario, when i remove "host=localhost" from file mybackup.conf, the promise is kept, because it's already on the mycatalog.conf file, but if i remove "retention=30" from the same file, promise is repaired, going a furthermore, if a remove any values from mycatalog.conf, it works. _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
