MSU East Lansing

Looks like I'll be in Michigan in early April, giving a talk or two at MSU. They'll be science talks, but at least one talk could be of interest to people likely to be reading this blog. Drop me a line if you're interested in coming.

It's not about the tools, dummy.

While reading A Conversation with Victoria Livschitz, I started to feel very unhappy with her answers. Then Grig sent me this nightmare, too. And I realized that I'm very confused about something.

As you may know, I'm a fairly recent convert to "agile testing". Not XP or test-driven development, per se; for me, "agile testing" just connotes applying many small tests to all levels of your app to test it holistically, combined with automated continuous integration to make sure that stuff stays working. I'm into "agile development", too, although more by accident than by design. I've been a huge fan of rapid prototyping since the first year I started programming -- I was producing crappy but functional TCP/IP code within 3 mo of access to a UNIX system, back in 1990. I've also been using revision control since then, too: I started with RCS, learned to use CVS in the late nineties, and now split my time between Subversion and Darcs. This is how I work, nowadays: I write some code, get it working, test it at some or many levels, write some more tests, check it in, repeat.

From reading these two articles -- Livschitz and the Nightmare article -- I conclude that many people do not develop the way I do. Moreover, people seem to be focusing on tools -- language features and revision control tools, in this case -- rather than on process. I don't understand why.

What am I missing? Do people truly, really believe that the computer is ever going to do a better job of ascertaining or interpreting their intentions than they themselves are doing? It seems like this is what the fans of static typing, new & better revision control systems, and UML all believe. I just don't grok how specifying behavior in ever more ontologically controlled ways is going to get you past the central social issues of software engineering, which lie in first figuring out what your software should do, and then communicating those intentions to other developers. These are social, not technological, issues, and they cannot be solved technologically. We can be aided by specific tools - personally, I find that using a fairly high level interpreted language helps with many of my problems -- but I was rapid prototyping in C long before I found out about Tcl, Perl, and Python. I struggled with RCS revision control in the early '90s, but I never thought that the reason I was developing bad software was that I had to lock individual files and manually merge contributions. I wrote tests before I had unit test frameworks. But I never confused the technological limitations of my tools with my failures of process, and I never stopped trying to learn better processes.

It is perplexing to me that such simple statements as "write code that incrementally approaches your goals" and "make your best effort to test that code" -- the two cornerstones of Agile Development and Agile Testing -- are apparently so difficult to comprehend or effect for so many people.

My best guess (and this is where my lack of experience may handicap me) is that people like Livschitz are trying to solve communication problems inherent in large team projects. It is necessary to work with multiple people to accomplish big things, and that's scarily difficult -- big game development scares the willikins out of me for that reason -- and I can imagine projects where it's impossible for any one person to grasp more than the basic elements of the overall design. It may well be that people are trying to substitute for proper testing with static typing and interface enforcement, and the purpose may be to use these tools to communicate between developers and teams across time and space. If this is the case, then I think they're being foolish. Unit, functional, and acceptance tests work just fine for communication at all levels of your application.

This general problem may be what Jon Udell is pointing out in his argument against standards, too. Don't try to communicate outside the code: make the functioning code itself your exemplar.

--titus

P.S. I am in no way blaming the Nightmare author for his problems. (It's clear he's never actually used subversion, which lets you solve merge issues in your own repository prior to check-in.) I am questioning the way his company develops, however.

Profiling

A cool post on combining KCacheGrind with cProfile. This is something I need to look into...

Web testing in other languages

On the off chance that you want to actually develop Web sites in a non-Ruby/non-Python environment, it's useful to know that you can also test them in the same languages. (I do think twill is a perfectly fine way to test non-Python Web sites; more on that anon.) Here's a PHP framework called Web Tester, and it looks like Perl's WWW::Mechanize::Shell is very similar to twill.

One entertaining thing is how enthusiastic people get about Web testing when they discover things like Web Tester (and, dare I say, twill ;). (I wuz there myself, back when.) It's really a moment of enlightenment for people when they realize that it's in fact relatively easy to write functional Web tests.

NSA Eavesdropping

I sent Bruce Schneier's article on false positives/false negatives on to several Bush supporter friends of mine. (Such people are rare at Caltech, admittedly!) One friend responded with an argument that (as far as I could tell) boiled down to (a) we don't have any better way to look for terrorist plots, and (b) we're all doomed anyway. I guess that's a variant of the Christian fatalist attitude that "Armageddon will be here soon anyway, so who cares what we do"? Not sure. Very odd.

Buying books online

Between Baen and Fictionwise, there are some good options out there for the kind of trashy books I like to read...

Potential twill coolness

One the of most rewarding things about working on a medium-term project like twill is the ability to periodically indulge in a nifty hack that people might actually use.

Here are two such minor hacks.

First, last night I whipped a quick link checker into shape. With the latest (0.8.4a5) version of twill, you can do this:

>> go http://www.idyll.org/
>> extend_with check_links
>> check_links
Gathered URL http://pywx.idyll.org.
Gathered URL http://alife7.alife.org/.
Gathered URL http://www.wrightflyer.org/.
Gathered URL http://www.idyll.org/~t/.
Trying http://www.wrightflyer.org/ ==> at http://www.wrightflyer.org/ ...success!
Trying http://www.idyll.org/~t/ ==> at http://www.idyll.org/~t/ ...success!
Trying http://pywx.idyll.org ==> at http://pywx.idyll.org ...success!
Trying http://alife7.alife.org/ ==> at http://alife7.alife.org/ ...success!

Particularly nifty things about this link checker:

  • since the link checker is built on top of twill, you can navigate to pages, log in, get/set cookies, set auth headers, etc. before link checking.

  • likewise, because the links are actually followed, referrer headers are set correctly.

  • as an extension, it serves as both a simple example of how to write more complex link checkers, and it doesn't get in the way of normal twill use.

(I plan to also add a little site crawler along the same lines as the link checker. Stay tuned.)

Second hack: tracebacks now give you the line number in twill scripts. Suppose you have an error (in this case, a contrived error asserting that a page failed with 'code 400') in a script. There are other ways of figuring what line it's at, but here's one that fits right into your traceback:

  ...
  File "/usr/local/lib/python2.3/site-packages/twill-0.8.4a5-py2.3.egg/EGG-INFO/scripts/twill-sh", line 20, in ?
    twill.shell.main()
  File "/usr/local/lib/python2.3/site-packages/twill-0.8.4a5-py2.3.egg/twill/shell.py", line 248, in main
    execute_file(filename, initial_url=options.url)
  File "/usr/local/lib/python2.3/site-packages/twill-0.8.4a5-py2.3.egg/twill/parse.py", line 155, in execute_file
    _execute_script(inp, **kw)
  File "/usr/local/lib/python2.3/site-packages/twill-0.8.4a5-py2.3.egg/twill/parse.py", line 196, in _execute_script
    execute_command(cmd, args, globals_dict, locals_dict, cmdinfo)
  File "/usr/local/lib/python2.3/site-packages/twill-0.8.4a5-py2.3.egg/twill/parse.py", line 106, in execute_command
    result = eval(codeobj, globals_dict, locals_dict)
  File "tst3:2", line 0, in ?
  File "/usr/local/lib/python2.3/site-packages/twill-0.8.4a5-py2.3.egg/twill/commands.py", line 119, in code
    raise TwillAssertionError("code is %s != %s" % (browser.get_code(),
twill.errors.TwillAssertionError: code is 200 != 400

Yep, the bold line is the actual line in the script file that I ran. Heh.

(I actually whipped this together for some unit tests where only the traceback was being printed. Very handy in that particular instance.)

One very amusing side effect is that coverage analysis records that line in that file, despite the fact that it's not actually Python code. Heh**2.

Automating your tests to run in buildbot

I spent many hours writing up a fairly shallow summary of how we automated the heck out of every damn type of test we used for our PyCon tutorial. (Grig even claims that

it's entertaining. OK, so I am your monkey. ;)

This is the thing to read if you want to know how we automated Selenium tests, FitNesse tests, twill tests, texttest tests, and egg build/install tests. It's structured as a narrative with explicit links to source and config files.

Let me say that I am immensely proud of this stuff and I think it could be very valuable to people setting up any kind of continuous integration framework. It took us many moons to work out the details of how to get this stuff to actually run automatically in buildbot, and it wasn't easy. But it all works!

Also, please comment on it.

Python ABI complaints

Only got one reply to my Python binary interface post -- thanks, zooko ;). Basically, "distribute your own Python with your app" is his answer. This is what Java program distributors often do to control the precise version of Java they're using, so at least Python is in good company...

Tomcat/JSP and httplib.py suckiness

I ran into two extreme examples of suckiness tonight, while trying to debug (what I thought were) related issues. (They weren't.)

First, it turns out that JSP cannot deal with multipart/form-data POSTs natively. Even worse, it just fails, giving you null values for form components. This violates the rule "fail in an obvious manner" and it also violates the rule "deal with data properly". What am I missing here? It must be something: this is 2006, folks.

Second, httplib lets you pass in HTTP headers with trailing newlines. Not such a problem, until you forget to put that strip() on the end of your base64-encoded HTTP AUTH header, and then all of your POSTs break because the Tomcat server on the other side of the connection ... neither handles nor complains accurately about the bad HTTP headers. Seriously, folks, why does base64.encodestring append a newline to the output?!?!? And why does httplib let clearly non-spec headers through?

Sigh.

The Rumors of Quixote's Death are Greatly Exaggerated

...and in 3 iterations, it will be Quixote.

But seriously, Mike Orr sparked an interesting discussion on the Quixote mailing list. Mike detailed a number of ideas for "modernizing" Quixote, and I'm strongly in favor of many of them. (Alas, I'm bogged down with other stuff (as always) and will be limiting myself to maintaining Quixote/WSGI and Quixote/sessions2 stuff.) Anyway, the thread is worth reading.

The main point that came out of the "Is quixote dead?" thread is this: Quixote works very, very well for a certain class of people, and it really is one of the few Web frameworks addressing that niche. Unfortunately the niche -- bare-bones object publishing -- is more utilitarian than sexy, so I don't think that Quixote will ever be a good candidate for the Bikini-Clad Python Web Framework Of the Month, but for the same reason I don't think it will be going away. Reassuring -- not that I have any problem supporting Quixote sites myself, but it's always nice to engage with other people on these things, too.

An amusing side that came out of the thread: at least one version of Quixote contains exactly 42 source files. Come on, folks, it's clearly the Answer!!

SQL testing

Some interesting links from Neil Conway on random generation of SQL queries.

statprof

With Andy Wingo's permission, I've plopped down an updated version of statprof, his statistical profiler for Python, here. You can check it out of Subversion thus:

svn co http://svn.idyll.org/repos/vallista/software/statprof/trunk statprof

This update to statprof makes it Python-2.3 compatible and adds a few options to the output.

SCGI and Quixote software

I've put scgiserver.py (a SCGI-to-WSGI server-side adapter) and session2 (a nicer persistent sessions module for Quixote) up on the same site.

Further consolidation: Cartwheel and FamilyJewels projects

I've also moved my two big bioinformatics projects over to my new dev server, at cartwheel.idyll.org. This way I can sync releases of different packages more easily; plus, I can use Trac. Huzzah!

Punk-ass bitching about Python's ABI

OK, so these people are obnoxious and full of themselves. But are they right?

To quote,

Python is unusable for software that cares about distribution, beyond very simple uses. The libpython ABI is not only horrifically unstable (every minor release changes it), but it also varies between distributions thanks to things like the brain-dead unicode ABI changing according to how it's configured. EG Python upstream uses UCS2 but Fedora uses UCS4. That means no using Python for application scripting and no shipping mixed C/Python programs.

If so, is there any official cognizance of these issues? Mostly I'm just curious: I don't think I've seen this much vitriol directed at Python in a while ;).

OO Types

An interesting series of lectures on OO types. (via LtU)

Buy me

Anyone know if this book, "Beyond Software Architecture", is any good? It looks interesting.

Writing articles, publishing screencasts, and breaking even.

Both Grig and I have a ton of articles and screencasts that we'd like to ginny up, based on various bits of our tutorial efforts. I've also been contemplating a series of articles on "twill and ... [ insert language of choice here ]". Now, it would be nice to start recouping the cost of our Web hosting, especially since we're not promoting a company or pimping a T-shirt line.

I have friendly contacts at O'Reilly and IBM DeveloperWorks, both of whom publish articles on related issues and presumably pay for them. I/we could also go the Google Ads route, and/or the Google Video route (for screencasts, which are likely to eat up bandwidth). Thoughts? Comments? I think we'd like to retain the articles on our own sites, too, although I'd be amenable to a various contractual limitations on that front.

(Obviously, if you're reading this and you're a publisher of online developer articles, get in touch ;).)

More PyCon notes.

Yeah, it's been over for 5 days... but I wanted to write about some other lightning talks I saw (in the 2nd lightning talk session), and also jot down some ideas that I'd had while at the meeting.

Lightning talks:

  • Martin Blais gave a short lightning talk on rst.el, offering reStructuredText support for emacs. Good stuff.

  • Someone -- didn't catch the name, or really anything beyond the name of the software -- presented software called "Alchemist", which looked like a great GUI for examining sales information across the US. Very impressive, very simple.

  • Ian Bicking presented on something called SQL-API, which looks like a very nice SQL library. He billed it as the next generation of the DB API, and pointed out that writing database APIs was boring and we should really get on with writing interesting code instead. It sounded pretty nice; I will almost certainly start using it myself, if it turns out to be EITHER well documented OR functional. ;)

  • Chad Whitacre's talk on testosterone and httpy was cute, although I found the "30 second wiki" demo unconvincing because he pasted in about 10 lines of source code ;).

(I missed a bunch of the lightning talks because I was chatting with someone about BioPython in the hallway -- my apologies to the speakers.)

Random Ideas

In the hopes that someone else gets there before me, here are some things I'd like to implement.

  • driving twill from doctests.

  • modifying nose to parse out doctests into individual tests.

  • syspath mangler class for use in saving, modifying, and restoring past sys.paths.

  • WSGI recorder/playback mechanism.

  • WSGI proxy (prolly based on TCPWatch code).

  • A simple Web crawler based on twill.

If someone has gotten there before me on any of these, please

drop me a line & I'll plug your code to the high heavens[0]. thanks ;).

--titus

[0] and I'll probably fold, spindle, and mutilate your code, too.

Lightning talk / screencast

After a nice blurb or two about my lightning talk at PyCon '06, I thought I'd practice my screencast fu by recording (a version of) my lightning talk. Without further ado, here's a screencast of a rerun of my lightning talk. (Yeah, I know it kinda sucks; I'm still working on the process!)

This took a fair amount of investigatory work. I started out by using SnapZ Pro X, for Mac OS X, which produced hideously large files of generally low quality. After lots of wasted effort, I gave up and switched to pyvnc2swf. I knew (from Chad Whitacre's efforts) that it could work, I just didn't know how well it worked.

Well, the short and sweet of it is that pyvnc2swf is a fantastic piece of software, and with only a minor amount of geek fiddling, I recorded the screencast above. (I actually gave up on using pyvnc2swf directly on my Mac; the screencast was recorded over the network, which is a pretty nifty feature of pyvnc2swf...)

Audio was more of a problem. I ended up recording with Quicktime Pro at the same time as I was doing the screencast, then saved as AIF and re-encoded with LAME before overlaying it onto the SWF file. There were a few mishaps in this process, because QuickTime doesn't save as MP3 (!?!?) and the AIFF file it generated doesn't contain good header info. Amusing nonetheless.

wsgi_intercept & mock_http

While I was at PyCon, an old acquaintance from Reed, Marc Hedlund, contacted me about wsgi_intercept. Apparently he needed to build a mock HTTP server to test client HTTP code, and upon discovering wsgi_intercept thought two things: (a) this is perfect! and (b) hey, I know this guy! Weird, eh? Pity he wasn't at PyCon...

Anyhoo, he very kindly donated a simple mock HTTP example to the project, and I just checked that in. So now you can mock not only the TCP connection but also the entire server side. Heh.

twill and django

In addition to Michael Twomey's overnight hack using wsgi_intercept stuff to test Django, some other people appear to be using twill with django.

Googling about, I found this interesting discussion of unit tests and twill. That led to this file (it's a download link) which was probably not meant to be entirely public, but too late, google finds all...

I looked over the source to understand how they were using twill. A few comments and thoughts, some for them, some for me:

  • twill's browser.get_html() doesn't actually return the tidy-ed or BeautifulSoup-ed HTML. It probably should, or it should at least have an option for it.

  • twill.set_output(fp) will now endeavor to redirect all output to the given fp, so they don't have to do the (painful!) stdio remapping any more.

  • I ended up writing my own test_follow_links for our MailOnnaStick app. Good idea. Should probably be in the std twill extensions lib at this point...

  • I was also thinking of adding in hooks to require that page visits be successful, etc. Looks like they could make use of those; good to know.

  • It would be cool to have random generators for forms that would let you fill in things like name, address, and zip fields with syntactically correect (or intentionally incorrect... hmmm...) input.

  • Use coverage.py to look at the code coverage of your twill tests. That way, you can pretty easily figure out what parts of your Web app are completely missed by your Web tests.

Anyway, no good idea how to find these people, but I'd be interested in hearing their success/failure stories with twill.

Final PyCon thoughts

Grig and I got a lot of positive feedback on our tutorial presentation, and I have a few thoughts to offer.

First, I had a cynical thought on why so many people signed up for the testing tutorial. The situation could be analogous to that of Christmas: some Christians go to church only once a year, at Christmas, to save their souls. Likewise, perhaps many people were thinking that they would be relieved of the need to test by coming to our tutorial.

Of course, the more optimistic take on things is that many people realize they need to test but they don't have a good idea of how to do it...

Second, several people (ok, two ;) commented that our tutorial was more technical, more involved, and higher-level than many (any?) of the other tutorials (!?!). I find this hard to believe, but, if true, there may be a demand for "entree-to-nuts", or maybe "soup to salad", not just "soup-to-entree", tutorials. (Evelyn Mitchell alluded to this in conversation with me, too.)

Third, the same people also mentioned that our tutorial was more technical than many of the other talks at the conference. I agree, in the sense that we presented stuff directly useful to & relevant to programmers. I've seen a few other comments that PyCon '06 was lighter on language internals and developer tool talks than before. This may just be another sign that Python is growing out of its gangly developer-only phase, but I think it results in a narrower conference. A lot of Python luminaries showed up and slouched around for a few days without giving talks. It'd be great to e.g. give a few python-dev people 15 minutes to talk about whatever they feel like.

Fourth, demonstrations are universally well-received even when they don't work all that well ;). So if you have the option, don't give a static presentation...

In other news, Robert Brewer has promised me a 100% solution to testing threaded Web apps, no doubt inspired by his own recent travails. So I'll be looking for that -- and now I know what you look like, Mr. Brewer...

--titus

p.s. Yes, I hear there was negative feedback too, and I'm somewhat perversely looking forward to getting the tutorial comments so that we have some explicit statements from people who attended the tutorial.

Saturday PyCon Keynote thoughts

The ssize_t fix for 64-bit machines will let me read the entire human genome (3 gb) into memory in one string!

The AST checkin for the Python branch looks very interesting. There was some discussion about what kind of Python interface to offer in the AST BoF which was mostly (AFAIK) off-topic, but very interesting. Naively I suggested providing a C-only interface to it in advance of the Python interface, to which I think the response was that duh, the argument really was about what the publicly supported interface should be, because once they had such a C interface the Python interface would probably be obvious.

Thanks, bazcamp

Whichever pythonista brought along their wifi hub and opened up 'bazcamp' near my hotel room -- thanks! I owe you a beer...

Lightning Talk Coolness

Apologies for things I missed; I know that I forgot to write some stuff down.

Ben Collins-Sussman-Google gave a great talk on replacing himself with an IRC bot. (Ironically, google fails to find valid URLs for his stuff...)

py.execnet is an evil way to control remote machines to which you have SSH access. (Holger Krakenmaster is the name I remember for the author ;))

Two guys from Columbia presented Tasty, "a full featured, efficient tagging engine accessible entirely through a REST interface."

The spec module, presented by David Binger, looks pretty cool. Unfortunately google has failed me... links?

Lightning Talk feedback

Some people type too fast.

I'll post more about the lightning talk stuff when I get a chance to do a proper screencast.

Quotable Bram

From Bram Cohen's PyCon '06 keynote on Sunday:

"The first rule of networking is ""don't reimplement TCP, badly"" ." (my paraphrase)

"Python faithfully reproduces all of the Posix API's crapitude."

"I spend very little time haggling with the language." (on Python)

"Advanced continuation usage breaks my brain. So does try/finally, actually."

"rsync is the morning-after pill of file transfer protocols."

"The funny thing about introductory rates is that you can keep them up for a while." (Yes, he's speaking about credit cards...)

"So, you see, credit companies count it against you if you apply for lots of credit. So what you do is you stack up all of the credit offers that come in, and you send them all out on the same day. Then they don't see the other credit applications." (my paraphrase)

"The only platform Avalanche runs on is PowerPoint." (Steve Holden, discussing Bram's opinions on Avalanche.)

"Programmers in San Francisco don't really take vacations. They just wait for their current employer to implode, and then take some time off before finding a new job."

"If you try to bring a bunch of lead-filled balls on a plane in America, you often end up juggling for the security people. 'Yes, these hand grenades are for juggling!'" (my paraphrase)

I am at...

The George Bush Python Convention '06

Lotsa "George Bush" monikers -- Sr., I think -- in Dallas. Why not the conference, too?

Miserable plane experience. Apparently some f*cker ran through security in Houston, occasioning a whole-airport shutdown & attendant delay. We came in from LAX and had to shuttle over to the Continental Express lounge area, which was packed with travellers in purgatory. To compare that place to the pits of hell would be a compliment to hell: the dull scent of despair mingled with the sweat of impatient people sweltering in underperforming air conditioning, and the relentless turmoil of people was relieved only by occasional murmurs of boarding stewardesses looking for the rest of the flight crew.

Really, it was bad.

We declined the honor and skipped back to the reservation desk, where we took a jet to DFW rather than Dallas-Love, which meant a longer cab ride but got us to the hotel pretty quickly in the end...

The tutorial, it is over!

Our Agile Development and Testing tutorial went well. We've opened up our development Web site and put up our handouts (at the bottom of the site). Comments & feedback welcome!

We'll also be presenting a "highlights of the testing tutorial" on Sunday after lunch, for those who missed the tutorial but want to see Selenium and buildbot in action.

Software that got mentioned by various people before, during, or after our tutorial:

  • Mousepose, a tool for demonstrations. (by David Goodger)

  • bitten, a continuous integration tool linked into Trac. (by Matt Good)

  • depgraph, for drawing dependency graphs. (someone in the audience -- sorry I didn't catch your name!)

The question that we didn't answer properly: why nose and not py.test.

And, finallyy, a note to self: when describing the use of Python wrappers to test C code, subversion is a fine example case.

A fictional but amusing LightningTalk title

While I did not know Bill Kent, his books sound very interesting.

A brief update

I'm in in the final throes of preparation for our tutorial at PyCon, next week. 42 attendees -- woot!

I spent the last few days hacking on our unit tests, fixing path-related issues and working on code coverage and profiling. I've also been adding a bunch of twill tests. We're up to 94% overall code coverage, and we're at a good resting point -- anything higher would involve testing very obscure corner cases that are better tested in other ways.

Miscellaneous observations:

  • coverage.py is fantastic, but it's difficult to control from within a customised testing infrastructure. I spent an hour or two today ripping out the implicit loading and saving of the coverage cache, so that I can precisely control when coverage is done and don't have to worry about stale coverage results.

  • I didn't realize until I started digging into it that nose, our unit test framework of choice, is based on unittest.py. It's pretty easy to get lost in all that code when figuring out whether or not you want to customize the unittest-based behavior or the nose-specific behavior.

  • Andy Wingo's statprof is pretty cool, and it's very easy to use. I spent a bit of time hacking on it, and in the process fixed the two lines that rendered it incompatible with Python 2.3. I've also dealt with some output-related issues. Andy's OKed my redistribution of the module, so I'll slap the fixes/patches up on a darcs repository soon. (Watch This Space.)

I'm looking forward to releasing all of our code into the wild. We've done a lot of work; even if the application itself isn't where I want it to be, much of our testing framework is solid.
