Add Frontend START expression in the match section
Every time I configure a frontend, I tie the Frontend match expression with the START expression;
it is the only way to make sure we do not end up with glideins that do not match any jobs.
Right now, I have to specify the two in two different places, once in the match section and once in the attributes section,
which are far apart and there is no obvious relation between them.
(not to mention having to define a GLIDECLIENT_Group_Start attribute to be sort of nerdy)
I think it would be better if we defined both in the match section, since they are both effectively used for matchmaking.
BTW: If the user decides to also define GLIDECLIENT_Group_Start attribute, we could just append to it.
Here is how it looks now:
<match match_expr='(job.has_key("DESIRED_Sites") and (glidein["attrs"]["GLIDEIN_Site"] in job["DESIRED_Sites"].split(",")))'> ... </match> ... <attrs> ... <attr name="GLIDECLIENT_Group_Start" glidein_publish="False" job_publish="False" parameter="True" type="string" value='(stringListMember(GLIDEIN_Site,DESIRED_Sites,",")=?=True)'/> ... </attrs>
and here is how it would look like in my proposal:
<match match_expr='(job.has_key("DESIRED_Sites") and (glidein["attrs"]["GLIDEIN_Site"] in job["DESIRED_Sites"].split(",")))' start_expr='(stringListMember(GLIDEIN_Site,DESIRED_Sites,",")=?=True)'> ... </match>
What do you think?
I am willing to implement it, if you guys agree it is a good idea,
BTW: I know it is annoying to have them in two different languages, too, and would love if one did not have to do that.
But that is too hard of a nut to grind for me.
#3 Updated by Igor Sfiligoi almost 8 years ago
- Status changed from Assigned to Resolved
- % Done changed from 0 to 100
Changed also the installers, to properly create the initial template file.
However, would be nice if the installer actually asked for the start expression (right now I just default to True)
