[Zope-dev] Test runner: layers, subprocesses, and tear down
I'm working on making the zope.testing test runner run tests in parallelized subprocesses. The option will likely be spelled -j N, where N is the maximum number of processes. I have it basically working, but have noticed a couple odd corners of the test runner that I'd like to clean up. They may be controversial, so I'll ask about them here first. I'd like to 1) remove the layer tear-down mechanism entirely, and 2) make (almost) all layers run in a subprocess. I want to do #1 because it would simplify the test runner code and no one seems to be using the functionality anyway. It also appears from reading the code that any tests run in a subprocess (and most are) will never exercise the tear-down mechanism anyway. #2 will add some process start-up overhead, but it'll only be one more process than is already started (and any reasonably-sized test corpus already starts several processes for each test run). The one exception is for running with -D or with a pdb.set_trace() embedded in the code under test. For that case we need a switch to say don't start any subprocesses at all, I suspect that will be spelled -j0. For motivation, some speed comparisons: running a particular test suite with 3876 tests (mostly doctests, and mostly functional) without the patch takes 6 minutes, 42 seconds; my branch runs the same tests in 3 minutes and 22 seconds (give or take) on a dual-core box with 3 simultaneous subprocesses. -- Benji York Senior Software Engineer Zope Corporation ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

AW: [Zope-dev] Test runner: layers, subprocesses, and tear down
Hi Benji Betreff: [Zope-dev] Test runner: layers, subprocesses, and tear down [... ] #2 will add some process start-up overhead, but it'll only be one more process than is already started (and any reasonably-sized test corpus already starts several processes for each test run).

I'd like to 1) remove the layer tear-down mechanism entirely, and 2) make (almost) all layers run in a subprocess. -1 in general. +1 if you do that only for -j N where N 1. Running all the tests in a single process has the following benefits: * test coverage analysis produces results that are correct (well, correct often enough -- but it has no chance at all when the test runner forks a subprocess) * import pdb; pdb.set_trace() works I want to do #1 because it would simplify the test runner code and no one seems to be using the functionality anyway. That's news to me. A while ago I went through Zope 3 trunk (it was pre-eggsplosion IIRC) and made sure all test layers defined in it supported teardown. Granted, FunctionalTestLayer() has allow_teardown=False as the default, for two reasons: * backwards compatibility: in olden days functional test layers didn't support teardown * paranoia: it is in general impossible to determine whether calling CleanUp().cleanUp() will correctly clear all the global state (someone could easily write a custom ZCML directive that changed a global variable and forget to register a CleanUp hook), so disallowing teardowns were the conservative safe choice. It is entirely my fault that I haven't evangelized the allow_teardown=True option for creating new test layers. It also appears from reading the code that any tests run in a subprocess (and most are) will never exercise the tear-down mechanism anyway. I guess that's fine for process state, but not so fine for external state (temporary files etc.). Hey, this might explain why SchoolTool's tests tend to fill up my buildbot's /tmp without cleaning up after themselves!

For that case we need a switch to say don't start any subprocesses at all, I suspect that will be spelled -j0. If that case needs to be supported anyway, what's the advantage of spawning exactly one subprocess when you run it with -j 1?

I know; for large test suites (by large I mean 40 minutes) I've been using an ugly hack (--odd/--even test filtering) that lets me use both CPUs if I manually run two instances of the test runner in two xterms in parallel.

[Zope-dev] TALES iterator odd/even reversal
Recently I migrated a large-ish app built on Zope 3.2 to Zope 3.4. (About time I hear someone mumbling in the audience.) One strange difference was that TALES iterators swapped the meaning of odd and even, i.e. p tal:repeat=item python: [1, 2, 3, 4] span tal:condition=repeat/var/oddoddspan span tal:condition=repeat/var/evenevenspan /p produces different results on Zope 3.4 than it did on 3.2.

Re: [Zope-dev] zc.testbrowser.real support for mozlab 0.1.9
I've checked in a branch with changes to the testbrowser.real code to
make it work with mozlab 0.1.9 (and firefox 3).
Hi Sebastian,
This is great. I spent all day yesterday trying to make this happen
and didn't get anywhere. Sometimes I wake up with a better idea as to
how to solve things, but I don't often wake up to find all the work's
been done!
I tried running the tests with Python 2.4. About half the time they
pass fine, and the other half fail something like this:
File doctest README.txt[40], line 1, in ?
browser.open('navigate.html')
File /Users/graham/development/patched_zc.testbrowser/src/zc/
testbrowser/real.py, line 201, in open
self.wait()
File /Users/graham/development/patched_zc.testbrowser/src/zc/
testbrowser/real.py, line 193, in wait
assert self.execute('tb_page_loaded;') == 'false'
AssertionError
though for varying pages with browser.open(). I don't understand what
could be causing it; why would that value be changed in between those
two lines? I guess the time.sleep() on line 191 implies that there's
something we might want to wait for. I increased it by 10x and only
got 1 failure out of 10, so I guess that helps.
Thanks,
Graham

[Zope-dev] Re: Test runner: layers, subprocesses, and tear down
Benji York wrote: I'm working on making the zope.testing test runner run tests in parallelized subprocesses. I have some recent experience parallelising (and distributing across machines) test runs. This was in Java, with TestNG and Selenium, but we learned some interesting things. We basically cut a 45 minute test run to 10 minutes by distributing the tests across three machines, each running a full stack (Oracle, JBoss, Firefox) and Selenium Grid. I realise you're not trying to do anything quite as complex as that, but a parallel test runner ought to be extensible to support distribution across nodes in a grid. The main challenge there is to distribute deployment of the code to run, and to sync test setup so that all environments are identical. I suspect you'll find this out of scope to begin with, but I'd keep it in the back of your mind. You will likely need some way of declaring tests that have to run in series. Sometimes that's just for sanity's sake, other times it's a requirement due to shared resources. A nice way to do this is to make it possible to annotate tests to group them, and then to be able to declaratively configure some groups as serial. Any functional test that uses a shared external resource will require this. TestNG supports (as far as I recall): - Run all tests (methods) randomly and parallelise - Run groups of tests (classes or declaratively specified named groups) in parallel, but run tests within the groups sequentially - Run all tests in series (i.e. single-threaded) We should probably use test layers as the main grouping mechanism here. If you could declare a layer as can be run in parallel with other layers or tests in this layer run in series, that'd be pretty powerful. I'm not 100% sure how this works with layers that derive from one another, and where you'd have two layers with a shared base class, though. Parallisation can offer huge (!) speed increases, but it can also be hard to debug tests. I'd be tempted to let single threaded by the default, safe choice, and let people opt into parallisation only when they know what they are doing. Most test runs are quite quick anyway. Test result reporting can be difficult. You'll probably need to collect all failures with tracebacks and report at the end. For long running test suites, this may not be ideal, since it's helpful to get early warning, so if you can find a way to get test output to be atomically output, then that'd be nice. Debugging stuff that happens in parallel with pdb is also tricky. It must be easy to turn off parallel running and to run individual tests in a single process for each debugging. To make this work with Selenium grid, we ended up building some infrastructure to manage environments (i.e. an allocation of database, web server and so on), and locks on those environments. We'd spawn one thread for each environment and feed tests to those threads as fast as they could run them. Each test run then grabbed an environment on setup, executed, and then released the lock for another test. Oh, and please don't get rid of any tear-down. You'll definitely need it one day. Letting environments go dirty is generally troublesome, and gets only more difficult when you may have multiple threads trying to use those environments at once. I don't know how you've structured this, but I'd consider whether one layer could be shared across multiple threads/subprocesses, or if it's always a one-to-one thing. I realise this is somewhat rambling, but I hope it's useful in any case. :) Cheers, Martin -- Author of `Professional Plone Development`, a book for developers who want to work with Plone.

[Zope] zope stops responding
Following a hard disk crash 2 weeks ago we have installed Zope onto a new server and all was fine until yesterday morning when Zope stopped responding and required a restart to get it working. It did the same at 3-30pm today. We are using Zope 2.9.0 on Centos 5.1 on a quad Zeon server with 4gb. Ram. At the moment the server is in quite heavy use with teachers trying to write reports for a deadline tomorrow. These are sent to a Postgres DB via psycopg. There is nothing in Z2.log or event.log to point me to the problem. I am therefore asking for advice on the sorts of things that can cause Zope to stop responding and whether there is anything we can do to mitigate against such an event.

Have you tried looking at it with the deadlock debugger?

Re: [Zope] zope stops responding
Yes, couldn't agree more with kevin. DeadlockDebugger is crucial. It won't change anything other than that you'll have information about what really needs to change. As an intermediate solution you can start to increase the number of Zope threads from 4 to 6 or 8 and see if that kills the CPU of your beefy server. Too many threads can hurt performance especially when working with badly coded external connectors that selfishly hook itself to the python GIL too much. A lightweight alternative to DeadlockDebugger is the table at the bottom of the Debug Information page in Control_Panel. If any of the dates in the first column in that table shows times longer than a second you have a problem with those requests.

RE: [Zope] zope stops responding
My experience is that increasing the number of threads past 4 does absolutely nothing to assist performance. Multi threads will help with the occasional long running request, but if its more than occasional then the thread list will eventually clog up no matter how many threads you have (and the more threads you have, the more they fight over the processor). The server sounds beefy, but since Zope is only going to be using one of those four cores, that might be deceptive.

Re: [Zope] zope stops responding
Hi, I does not agree with You, because my servers runs with 20..150 threads, because lower number of threads makes for somebody infinity waiting and Zope under load responding very slow (with external database access).

[Zope] Problems with Zope + Apahe and exUserFolder logins
Hi everyone. I am migrating my web application to a new server and I am trying to configure Zope + Apache as described in http://wiki.zope.org/zope2/ZopeAndApache . I previously used fast-cgi to communicate Apache with Zope and it worked just fine. I use exUserFolder to store my users in a postgresql database. Everything seems to work fine except when I try to login to a restricted area through port 80. After debugging a bit (unfortunately I'm not any Zope guru) I've noticed that the username and password variables which are posted from the login page are located at the HTTPRequest? http://wiki.zope.org/zope2/ZopeAndApache/createform?page=HTTPRequest.stdin property when the page is accessed through the 8080 port, but they are not present when the page is accessed though apache. Anyone has any clue about what might be going on? Thanks a lot. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
