This is the tracking bug for the work on the on-demand update testing system, including the testing daemon and the test executor. It also includes the build staging script, which is currently the first WIP on Bug 628659. I am intentionally not including that bug as a dependency, as the bug is more sweeping towards handling updates and bfts, along with perhaps eventually executing the tests themselves. So, instead I simply note it here as a related bug. I'll follow up with patches generated to get these components into our hg repo.

OK, version 2. This does all the on-demand release stuff, as well as incorporates most of the previous review comments. Listener script runs as before. Pusher script runs like: release_push.py [options] bft branch release_push.py [options] update branch channel Reply to previous review follows: (In reply to comment #2) > >+++ b/heartbeat-emitter.py > > Can we please push all files into a sub directory?

Can those messages be > distinguished? One emitter needed somewhere for the entire system (across all clusters), no harm if more than one is running. The deal is that the sockets close if you don't keep them alive by sending traffic. The heartbeat is strictly a keepalive. This is a bit of a hack. Eventually heartbeat/keepalive move into the pulse platform itself and we can get rid of it. > >+def output (message): > >+ print message > > What's the purpose of this wrapper function?

The general rule is to use now() when you're doing something that displays to console, since you generally want that to be system-local. utcnow() is generally only used for data structures so they're time-agnostic. In this case, it's a message for debug use so you can see when the heartbeats froze up or crashed out, so system-local is appropriate. As it happens, most systems we'd run this on are UTC anyway, so doesn't much matter. > >+ usage = """usage: %prog [options] branch channel >... > >+ did not supply a cluster will run update tests.""" > > This comment should be global. Then it will be automatically used when > --help has been specified. There's no automatic about it. Check your own download.py script--you have to specify description=__doc__ to make that happen, and the description kwarg isn't even documented for that constructor. The way I did it is exactly how the optparse docs say to do usage strings. Plus, I tried moving this stuff to docstring and doing it the way you suggested. the description=__doc__ thing hoses formatting in multi-line docstrings; the only reason yours work are they're single line. Upshot is, I'm doing it the standard way, had problems doing it the non-standard way, and am going to keep it as-is. > > >+ parser.add_option('-c', '--cluster', > >+ action='store', type='string', dest='cluster', > >+ help='name of cluster to push to') > > This is an option, so what are we default it to? It defaults to "None". Options can do so, what with being optional. :) I did put a [default=no cluster] in the help string though. > > >+ parser.add_option('-p', '--platform', > >+ action='store', type='string', dest='platform', > >+ help='platform to push to [default: all]') > > Please specify the default value via 'default="all"'. Default isn't "all". That would be a platform named "all". Default, as above, is None, which internally means "no specific platform," which is to say, all of them. The reason you do these this way is because you have no idea what people will want to do in the future. So you don't set up magic sentinel strings that mean what you want because someone might use them and get awfully confused. Instead, you use a value like None or undefined or what-have-you because they can't possibly specify that. It's good interface practice, whether you're talking functions or scripts--magic values are bad. > What does it mean technically if we do not set the cluster? Do any listener > which receives the signal start to execute those tests? I think we should > always include the cluster property with the right value (specific machine > or 'all') set. Everything without a cluster is logically lumped together into a "no cluster" category. So if you send a request with no cluster, all the listeners with no clusters will react to it. If you send a request with a cluster, only listeners for that cluster will react to it. I changed the wording in usage a bit to reflect this and make it a little clearer. I don't really want to make this a required param--it's a PITA to type every time you do a request, plus you have to know what the exact name of the cluster is. For now, I recommend editing the default when it's staged on a machine so it doesn't have to be retyped. Once I have a better idea how this is being used (directly for medium/long term, web front end, what?) I'll revisit this and see if a conf file makes sense or what. > >+ # Did we specify platform? If so, add the platform key >... > Same comments as for cluster. On this one, "don't specify the option to run all platforms" is fully appropriate. Platform is a limiting option; the default is to run everything, but you can address one in the rare case you need to. It differs from cluster in that your normal case will almost always involve not specifying platform. So, it'll stay an option. > Please use placeholder descriptors here like %(CLUSTER)s. Please see the > scraper package. I switched everything to them (though I use PEP-8 standard of lowercase names :) ). I have mixed feelings--they crap up the code in the "one substitution" case, but they're clearer in the "multiple substitutions" case. I'm not sure what I think we should do long-term, but for now went with it. > >+ # Disconnect to be nice to the server > >+ pulse.disconnect() > > Can there be any exceptions? If that's the case we should handle disconnect > in the same way as in the heartbeat scripts. Yeah there can.

Please reference its id. Oh, come on. I'm not going to file a bug for every TODO that I leave as "this might be a good idea" in a script. It's a place to expand later and I'm noting the place for -when- it comes up, not marking a specific defect. So, I removed the comment to make you happy--the script does what it does, and that's it for now--but this one wasn't an appropriate review remark IMO. > > >+# Define a callback > >+def got_message(data, message): > >+ global platform > >+ global script > >+ global cluster > >+ global debug > > Do we really have to redeclare those global variables? I have never seen > that before. Then you haven't used global variables very much. You need to put the global <var> in any scope (other than global) which you want to use them in. Those commands pulled them into function scope. It's necessary to share them between the main() and the callback. There's no other way to do so. So, expect global decls in each of those functions. > > Nit: printing platform twice?

We should clean-up correctly. Doesn't apply to listener scripts--there's no connection to clean up that's not completely encapsulated in the pulse library. There is the need to ack() messages (though this is somewhat optional), and I added a try..finally in the central dispatch routine to do that. In addition to the above, I made some pretty large changes to the script logic and highly simplified the code away from the mass of if..elif..elses that were handling the listener reporting before. Your suggestion of always making sure the keyvals were defined in the message helped simplify things, as did some basic refactoring. You should find it somewhat easier to follow now, but ask me any questions you might have.

Summary: Tracking Bug: On-Demand Update Testing → Tracking Bug: On-Demand Release Testing
Gonna eat some late night crow, now. (In reply to comment #3) > > >+ p = subprocess.Popen(args) > > >+ retcode = p.wait() > > >+ # XXX: should do something if failed > > >+ print ' finished, return code: %s' % retcode > > > > Please mention that we lack this capability right now due to a bug in the > > automation scripts.

Just realized you thought the XXX was referring to the fact that the other scripts don't return retcodes, in which case that was an appropriate comment. It doesn't, it referred to the idea that the scripts should email or something on a failure--really was for expanding these particular scripts. I figured by the time we got around to that, the others would be returning codes anyway. > > >+# Define a callback > > >+def got_message(data, message): > > >+ global platform > > >+ global script > > >+ global cluster > > >+ global debug > > > > Do we really have to redeclare those global variables?

You need to put the global ...or I haven't. :| You do have to redeclare in any scope for which you want to modify them. You don't if you only want read-only access to them. So, I could take these out of the callback, since it doesn't write to the variables. I will say that I see an advantage to keeping them, though--you get weird behavior if you -do- write to something that should be global without doing this. It'll create a temporary local variable instead, which hides the global one. I had that situation come up when developing these, and it was actually kind of hard to figure out what was going on. It would've been an easier bug to catch with everything having write access. But I could go either way.

I only had read access to global variables. So leave it as you say.
Status: NEW → ASSIGNED

Realized I'd forgotten a qrefresh anyway, and needed to update. So, I also removed the callback's redundant global statements.

The Python docs explicitly mention the description > parameter (http://docs.python.org/library/optparse.html) Sorry, I must have been unclear and we crossed some wires. The PEP-8 comment was concerning the string placeholders. You were using all-caps. Since they correspond to key names in a dict where the keys are used as fields, you'd normally use variable-style naming. Where I said I was doing it the "right" way, I was referring to the optparse docs you also reference. I'm following their examples for setting up usage statements exactly. Regarding description, you're right. I only found it as an option on OptionGroup before, but I see now that I missed it listed under the constructor params. However, description is also documented as only handling a single paragraph, which it reformats for the terminal. As I'd said before, before I read that I tried using your method of assigning the docstring to description. Trying to run multi-paragraph text spits out malformatted garbage. It's possible the very top paragraph could be the global docstring and double as description, but what you're doing with it doesn't represent any sort of standard I found; it's fine, but it's just what you've chosen to do with it. I chose something different, and pretty much stand behind that decision. OTOH, if I missed a standard for that somewhere, please show me where it's independently documented and I'll definitely make the change. > > >+ platform = args[0] > > I hope that we can get rid of this workaround in the future by correctly > identifying the os version. Lets see if I can get to it this quarter. Sure. I don't really see it as a workaround though--you might want a 32-bit-platform daemon deployed on a 64-bit OS. I wouldn't assume this should be changed. > > >+ print 'Listening for requests that include platform=%(platform)s' % \ > >+ {'platform': platform} > >+ > >+ print 'Will run update tests using script=%(script)s' % \ > >+ {'script': update_script} > >+ > >+ print 'Will run bft tests using script=%(script)s' % \ > >+ {'script': bft_script} > > nit: 4 spaces for indentation My intention was to indent it under the printed statement. I used four-space indents, and they're at the first tab stop with 4-space indents that lands under that statement. I guess I could go with aligning the { with the '; that's probably more consistent with PEP-8's instructions for hanging indents. 4 spaces from left margin was pretty cluttered looking when I tried it. That's going to be a lot of small changes throughout the files though. Any any rate, I'd like to hear your opinion on how you'd indent this. > > r=me with the comments addressed and remaining questions solved. I appreciate that! With the scope of the requested changes, though (they're small but touch a lot) I think I'd want a second review.

* BFT -> functional DONE * test_bft/test_update DONE * Remove default cluster DONE * Use docstring for description DONE * Hanging indents on prints DONE Since I needed a re-review anyway, I went ahead and made all requested changes. I don't see a point on putting something in we don't both agree is pretty good. A little commentary: * All references to BFT now say functional (including the command line param). If it turns out this is a pain to type, we can loop back and shorten it. But you're right, that run isn't just BFTs anymore. * I removed the test_bft/test_update routines in favor of just exec'ing. In order to make that work better, exec_test() was breathed on a little to just take a variable arg list (part of what those functions did was build the args list). * Cluster is no longer optional, and is now a positional parameter. That also let me simplify both the screen_request() function and let me remove the get_cluster_str() function that accounted for None clusters. * Because that simplified the help string considerably, I moved it all into the docstring and used description=__doc__ as suggested. I will say, though, I did a fair amount of research on this after your comment. This is a nice shortcut for short descriptions, but really isn't a standard. It's also not viable for a multi-paragraph help block, because that description will always go at the -bottom- of the usage, not the top. So there's no good way to just carve off the high-level part of the usage and put it in the docstring, since you usually want to see that first, and description can't be multi-paragraph. The most common way I've found for a long usage statement is to do what I originally did and make a long usage string. The second most common way was to subclass OptParse and rewrite its renderer, which'd be a bit of overkill. argparse fixes these problems by giving you more options for formatting and allowing documentation of positional args. But we don't get that until 2.7. The key here was the help getting simpler, and that let me do it the way suggested. But for complex help, I'd expect it to be the way I had it. * I fixed all hanging indents and also normalized strictly to 80 char width. Neither you nor I really had a solution that reflected PEP-8. Between that and the Google Python style document, I was able to decide on: + print 'Received request for cluster=%(cluster)s' % { + 'cluster': requested_cluster} ...which I used when no value fit on the first line. If any of the values went on the first line, I vertically-aligned under them as specified in PEP-8. Where I had strings that went over the 80 char line, I also fell back on Google's guide and split them by putting them in parentheses so they'd implicitly concatenate across lines. So that's what that's about when you see it. Google's doc is here: http://google-styleguide.googlecode.com/svn/trunk/pyguide.html This should be in pretty good shape at this point. Take a look and let me know what you think.

Comment on attachment 547595 [details] [diff] [review] Scripts for on-demand release testing, v2 Looks fine. I haven't run the scripts to verify the functionality but I think you did a good chunk of it already. Lets get it landed and distributed to our machines for release testing. Thanks Geo.

Geo, can we get this landed this week? I know we haven't had time last week, but we should get this project finalized soon. Thanks.
Landed as http://hg.mozilla.org/qa/mozmill-automation/rev/ec80e0b806f7 Wasn't a matter of the delay, per se. My hg access was still broken when we went on work-week, and I was trying to get it fixed. I'm OK now.
