an error occurred, returned 127

[Xander Cage]

hi all,

got the following in the outputs...

root@aixtest01: /var/cfengine/outputs # cat cf_aixtest01__1625771019_Thu_Jul__8_21_03_39_2021_180
   error: Finished command related to promiser '/var/cfengine/modules/cfe_db_check' -- an error occurred, returned 127
   error: Method 'cfe_db_check' failed in some repairs
   error: Method 'b0021_cfengine_internal_db_check' failed in some repairs
   error: Method 'itsv_autorun' failed in some repairs

when i run the module "per hand", it works.

root@aixtest01: /var/cfengine/outputs # /var/cfengine/modules/cfe_db_check;echo $?
+CFE_DB_OK
0

also when running the bundle manually it works...

root@aixtest01: /var/cfengine/outputs # /var/cfengine/bin/cf-agent -KI -b cfe_db_check --show-evaluated-classes=CFE.*
    info: Using command line specified bundlesequence

R: CFE internal Databases are good.
Class name                                                   Meta tags
CFE_DB_OK

any idea whats going on?

policy:

bundle agent cfe_db_check {


commands:

    "$(sys.workdir)/modules/cfe_db_check"
                                      module => "true";

reports:

    CFAGENT_HANGS::

                       "Agent hangs: The Purge was initiated.";

    CFE_DB_ERRORS_FATAL::

                       "Fatal: CFE internal Databases are bonkers, cfengine killed and cleanup procedures triggered.";

    CFE_DB_IN_DIFFICULTIES::

                       "CFE internal Databases are in danger.";

    CFE_DB_OK::

                       "CFE internal Databases are good.";


}

ok after setting module to false, this  was shown...

 notice: Q: "...e_db_check ": python3: No such file or directory

changed the python3 path in the script  and error is gone, AIX "speciality" like always, python3 was not in standard env and

of course cf-agent knows noting about this aix crap.

[Marco Marongiu]

Doesn't CFEngine come with a python interpreter? Haven't the pc with me and can't check but if so, can't you use that one so that you are sure it's always there at a certain path?

Ciao

We do not vendor aka provide a python interpreter. We do attempt to find the "best one" and make a symlink to it for use in our package modules and such.

https://github.com/cfengine/masterfiles/blob/0045adabe96b72a86555ea8c23139f3c284d680e/cfe_internal/update/update_policy.cf#L87

So you could use that path: $(sys.bindir)/cfengine-selected-python typically that would be /var/cfengine/bin/cfengine-selected-python.

ah, good point, this "find python and make sysmlink" is another thing which never worked in aix. i will take a look at it, and do a PR if i find out somehting.
