crontabs and common paths bundle #14

neilhwatson · 2012-02-28T22:11:58Z

Crontabs is self explanatory. The paths bundle I'd like to be a community
effort to catalog the paths to commonly called commands.

+	files:
+
+		"${g.nhw_crontabs}/${user}"


This should be modified to use paths.crontabs instead of g.nhw_crontabs.

Change g.nhw_crontabs to paths.crontabs.

Hi Neil - thanks for the submission! I think the paths bundle is an excellent idea.

I have made a couple of comments on some lines.

nickanderson · 2012-02-29T01:39:00Z

I like the paths idea too. Maybe its just me and my brain wanting to limit scope, does anyone else find it easier to read a commit that is just a single sketch?

zzamboni · 2012-02-29T01:42:01Z

That's the idea in general - one sketch per pull request. In this case I think it made sense to bundle them because one uses the other.

references in the pull request.

Should this class be prefixed with sketchname_bundlename ?

or maybe sketchname_bundlename_${user}_crontab_repaired since I see your classing a command below on root_cron_repaired.

nickanderson · 2012-02-29T03:13:56Z

neil what do you think about the bundle name change from cronjobs to cronjobs_add since it appends if not found. I think that would leave logical namespace for something like cronjobs_delete and other patterns for dealing with cronjobs, perhaps cron_d style related.

nickanderson · 2012-02-29T03:30:04Z

I was thinking sketchname of cronjobs like you had but the only bundle you submitted in that sketch was also named cronjobs. I thought maybe just rename that bundle and we can add more cronjob related bundles to the sketch am curious what others think though before you keep making changes on my whims :)

zzamboni · 2012-02-29T03:56:17Z

I agree - I think the sketch should be named cronjobs (or just cron), with the bundle names indicative of their function (e.g. cron_add, cron_delete, etc.)

Are these metadata values for ostype, tested, and cfengine_version supposed to be valid cfengine classes?
Which ones are required?

Should there be a comma between the name and email address?

I ask because I am thinking ahead to what the not yet finished tooling is going to want to expect and it would be nice to have a tool that could be used to validate a submission

In this case, ostype should be unix, which is a hard class defined by CFEngine on any Unix-style operating system. The author should preferably be Name <email@address.com>.

Indeed the idea is that we'll have a tool that can validate and submit sketches, and also one to install them.

Which if any fields are required?

neilhwatson · 2012-03-01T02:21:14Z

I have one other large sketch to add. Is it better to wait for this pull to complete and then start a new one?

nickanderson · 2012-03-01T02:29:24Z

Your in the same spot I was, your clone is progressing at a faster pace than upstream. I don't know what the official stance is, but it is probably best to get your stuff on a feature branch.
I found diasporas workflow to be pretty helpful, its concise at least.
https://github.com/diaspora/diaspora/wiki/Git-Workflow
Diego also pointed me to this which is a good read.
http://nvie.com/posts/a-successful-git-branching-model/

I see one more thing that needs to be addressed in the submission,
There is supposed to be a cf file matching the sketch name, so if you just rename system/cron/cronjobs_add.cf to system/cron/cron.cf and leave the bundlename as is. Then maybe diego can merge the pull request.

Then you should update your clone from upstream, and create a feature branch off of it where you can add your new sketch and submit a pull request for that.

I just had to work through doing that yesterday so if you need help let me know.

zzamboni · 2012-03-01T02:57:13Z

Hi Neil,

The best is to start a new branch for each sketch, then you can submit multiple pull requests simultaneously.

If you branch before your changes are merged and do a pull request on
that branch that pull request will include your other sketches.

Are they supposed to be human or machine readable?

I think in the metadata file they are supposed to be machine readable
probably the same classes that cfengine defines so that tools (not yet
built) can search for things or warn when installing if your
installing on a machine that classes dont match.

In the Readme.md I would guess either machine readable or human readable.

Nick Anderson nick@cmdln.org

Yes, ostype and tested in the metadata.txt file are supposed to be CFEngine class names. I will clarify this in the guidelines document.

That's why you never develop on your master branch - that way every branch starts off with the "clean" state of the master branch, without any other changes, and they can be merged independently.
