cool! Big thanks and good luck. I really think it is worth

Ah, this trailing slashes. When writing Apache Rewrite Rules

problem.

b.t.w. Just looked at a small Beans/JSP/Servlets shopping cart 
example in the JBuilder 4 Enterprise Edition. So much Java code 
for so little. With Webware/Python it is almost trivial to 
reimplement it. I beginn to see clearer how precious Cans are
in the Webware environment but this pathinfo stuff really 
influences how I will design the reimplementation of my stuff.

I think a formalized task manager is a great idea.  We had intended to get
to something like this when we did the initial session sweeper stuff.

I'd like to suggest a slightly different approach, however.

It looks like in the code below, you'd spawn a thread for every task.  This
seems messy and would require each task to, possibly, manage it's own sleep
cycle, etc.

My alternate suggestion is a more cron like system.  We'd have one main task
thread that would wake up every 5 seconds or so, and go through a list of
Task objects to see if any need to be run.  The Task class could specify
whether it would like to be run from the TaskManager thread (for quick
tasks), in which case we would just call the Run() function of the Task
instance, or it could request to be run in a new thread (for longer tasks,
like a session sweep), so it won't tie up the TaskManager thread.

The Task class would define a function called runTest(currenttime) that
would return true to indicate it should be run now, or false to say don't
run now.  The default implementation might just check to see when it was
last run (from an internal variable) and see if it should be run now by
comparing the last run time +  Task.interval to currenttime.  Then more
advanced Task classes could just override this function.

Does that make more sense?  Or was I just missing something in the below
implementation?

In the last discussions we touched implicitely some
task scheduling questions. I looked at the Application.py
code to search for a place, where one could
plug that in (better than a TaskKit?), because I think 
this could become important for many things. You
can do it with OS mechnism, but to have it crossplattform
in the application framework would be really nice and 
a great plus.

One scheduling example is realized for Sessions:

in __init__.py you have

if useSessionSweeper:
  self.startSessionSweeper()

def startSessionSweeper(self):
def sweepSessionsContinuously(self,close):
def sweepSessions(self):

Let's make this more general (Task seems a good name). 
Look at the following python code + pseudocode,
where I just show what I have in mind, not
every detail (sleeping time, ...)

Application(self,....,useTasks=1,..)

def __init(self,...)
  if useTasks:
    self._tasks = get tasklist from Application.config
                  or by a name convention *Task.py
    self.startTasks() 
 
    # possible Tasks: 
    #  * Session, 
    #  * Scheduling of "Webware cronjobs"
    #  * Generate static pages
    #  * update in memory information


def startTasks(self): 
  #self._tasks could also be a parameter
  for task in self._tasks:
    task.run(app, close)

class Task:
  def run(self, app, close):
  # for Session this is called
  # sweepSessionsContinuously: 
  # there you need app.running, app.sessions(),

class SessionSweepTask(Task):
  def run(self, app, close):
    while self.running:
      self.sweepSessions()
      try:
        close.wait(self.setting('SessionTimeout')*60/10.0)
      except IOError:
        pass

  def sweepSessions(self, app):
    sessions = app.sessions()
    ...

class CalendarTask(Task): 
  # this is for tasks which run once or
  # no seldom. use a Task subclass if
  # your task ha to be scheduled often 
  #(e.g. every Minute..)
  # use mxDateTime for this kind of stuff
  def run(self, app, close):

  def run((self, app, close):
    #generate staic pages

###########################################################
in Application.config use:

'Tasks':  ['SessionSweep', 'Calendar', 'PageWriter'],

hey, hope you like this proposal. I'm sure I forgot something,
but it looks ok afrer reading it several times :-)

The amazing thing with Webware ist, that you can go down
to the framework, understand and even change it. After 2 years 
of Zope programming I still have no idea how it works under 
the hood!

Hmm, so you seem the ideal person to code it :-)
I'm not shure anymore that I'm able to implement it myself, because
there are quite many things to take care of, but I'll try
if there's nobody else...

No, makes perfect sense. 

I'm just trying to digest all the positive feedback I got to my
proposal. 

Starting a new thread for each task was the first approach, because I 
assumed, that there are not many "heavy weight" tasks (the "cronjob
task" 
was supposed to manage the many jobs which are run once or seldom..).
I feared that polling many tasks ("do you want to run?"), which in most 
cases do nothing, would be a bad idea, but your approach mixes both
ideas, 
which is probably the way to go. You have maximal flexibility and
can exactly do wat you want.

cool ideas from all of you. Let's make the TaskManager happen :-)

We'll work on it together.  I write the least elegant classes of anyone 
around here, so I'll focus on the Application integration through a 
mixin, If you'll think about the Task class, etc.

The code to manage the sleep cycle would be captured in Task. e.g., task 
implementors don't have to write this code because they inherit it.

Polling every X seconds is generally a poor technique (in this case X=5). 
If you need granularity less than X you are out of luck. Unless you can 
change X. But be careful not to ever make X bigger; one of your tasks might 
rely on it and break.

My point is that X is going to be "wrong". Polling is always too much or 
too little, and when you tweak it you have to be very careful that you 
don't break anything.

Also, if your tasks are really running every 5 minutes, then running 
through the list an extra 59 times is very wasteful.

Seems like implementing runTest() to return "self.lastRunTime + 
self.interval > curTime" is just as messy or more so than 
"self.waitFor(self.interval)". Both approaches requiring a line of code, 
but the waitFor() and waitUntil() are plainly readable.


>Does that make more sense?  Or was I just missing something in the below

Besides the above, consider that implementing polling in the system I 
originally described is 4 lines of code:

class Poller(Task):
     def run(self):
         self.poll()
         self.waitFor(5)

Given polling's disadvantages and the ease of implementing it as a specific 
type of general purpose task, I believe the earlier proposal is better.

OK, Chuck, you're probably right.  I just don't like the idea of spawning
unecessary threads that will sleep mose of the time.

Tom, do you have time to do this?

What about having a single scheduler thread that sleeps until the next
event? Basically, when you add a new task to the task manager, it
recalculates the "next event", wakes up the presumably sleeping scheduler
thread, which puts itself back to sleep with an updated "next event" time.
When that timer expires, the thread wakes up and executes all events
scheduled for that time slot.

Best of both worlds -- only one sleeping thread, and no polling.

good solution. (can be quite involved to compute the next task time...).
I think starting with new threads like I did is a good first
start, then we refine it step by step.

B.T.W. My first simple tests showed that

self._close.wait(seconds)

is quite imprecise (self._close =Event())

compared to

sleep(interval), but how to stop a "sleep" when shutting down
the AppServer?

You beat me to it. I was going to post this idea today.

What are you doing up at 8:27am anyway? I thought you slept form like 5AM 
to 12PM or something...

In any case, the other thing I was going to point out is that WebKit 
already spawns 10 threads for it's thread pool and Apache 1.3.x on Windows 
reports having 51 threads on Windows ME (I don't know why, I thought it was 
forked, not threaded).

The point I'm leading up to is that [a] we could easily spare another dozen 
threads and [b] most applications aren't like to even get up to a dozen 
tasks anytime soon.

I think the one-thread-per-task approach is fine for now.

Yeah, using a plugin-based scheduler would be good. That way, we can
optimize the scheduler over time, and clients can explicitly choose a
scheduling method, if they need to (for instance, if they need finer
granularity than that offered by any sleep-based solutions).

As for keeping track of the next task time, it's actually not that bad. 
You maintain a min heap of scheduled times so that the next "interesting"
time is at the top of the heap (with a list of attached events to run). 

The actual computation of next task time can be as simple as adding
seconds, and as complex as parsing an intricate schedule specification
(see, of course, crontab(5), and Perl's Date::Manip library). Of course,
if at all possible, we should reuse existing code to do that part, but I'm
unaware of any Python module approaching the raw coolness of Date::Manip
for such tasks :)

Sez you :) I've got plenty of plans for tasks running rampant. However, I
can also implement the snazzier scheduler later, after I port Date::Manip
to Python :)

That's why we're using the close.wait() thing.  When you do a ctrl-c, 
(Keyboard Interrupt), sometimes the sleeping thread will get the 
interrupt, but the main thread won't see it, and things get messed up.  
That's where the IOError came from, if memory serves.  If the sleeping 
thread is using close.wait, maybe that throws an IOError?

Anyway, don't worry about it for now.  Just use sleep, and we'll refine 
later.  Also, we should make that thread daemonic, so if we're exiting 
we don't have to wait for it to wake up.  We'll still call 
Task.shutdown() or something like that for all the active tasks, but 
we'll just let that thread die off.

Idea:

Instead of usage OneShot adapters to start Monitor.py from Cgi or FastCgi 
adapter - if
It fails connection with AppServer.

I was thinking about that myself.
I am working with a hosting provider that frowns on long-running processe=
s.
I do not expect a lot of traffic, but it would be nice to start the
appserver when a visitor does come.  "LazyStart" could

    if webware is running:
        connect to it to handle the request (as WebKit.cgi currently does=
)
    else:
        fork and fire up appserver
        run as OneShot in the parent process

Hopefully appserver will be running by the time the next request comes in=
,
and the response will be that much faster.  The running appserver could a=
lso
kill itself after a specified idle time, to keep the hosting company happ=
y.
(They have a cron job that does this anyway.)

This idea could also be incorporated into mod_webkit for extra
robustness/flexibility.

Issues:
    How does the appserver signal when it is ready to serve?
    How to avoid spawing several appservers if the first one takes a long
time to start?
    How does appserver signal when it is shutting down (while finishing
already queued requests)?
    For high-traffic sites (on an SMP machine) does it make sense to have=
 a
pool of servers? (if so, load-balancing enters in.)
        (appserver is already threaded, which is the best you can get for
Python on a single-processor machine.)

Just some quick notes on this topic that you've brought up:

Perhaps the status of the app server (INITIALIZING, SERVING, SHUTTING DOWN,=
=20
DEAD) can be contained in a "status.text" file that might also contain a=20
time stamp for that message. Also, the app server needs to kill=20
address.text after it shuts down, something that I still don't think it=
 does.

It is possible to use the file "appserverpid.txt", but it(he) should be 
unset
At completion of the server.
And to fulfil check of real existence of the process with it pid.

(Можно использовать файл "appserverpid.txt", но он должен обнуляться
при завершении сервера.
И выполнить проверку реального существования процесса с этим pid.)

I am trying to optimize my webkit servlets and I was browsing the webware
admin pages.  In the Servlet Cache by Path, I realized that I do not fully
understand the following settings:
created 1 (sometimes this is greater than 1)
instances Queue: [] lock <lock object at 00CDC738>
path C:\Inetpub\WebWare\WebKit\vcmr\select.psp
reuseable 0 (sometimes this is one)
threadsafe 0 (this is never one)
timestamp 1001553935

Can anyone give me a quick explanation on what these settings are and how
they affect the web servlets and performance?

Additionally, does the performance increase with more threads for the App
Server?  Does the amount of threads have anything to do with the number of
servlet paths (I have noticed that number at 11 when I only have 10
threads).

Thanks for any help that can be provided.

Why are you specifically trying to optimize them?  What kind of performance 
issue are you having?

BTW My number one optimization technique is to cache any information my 
servlets compute that can be cached. That means either computing in 
__init__, or storing computations in self.attributes which then get used 
the second time around.

The "settings" are really in WebKit/Application.config. What you are seeing 
here is a _data structure_ that the app server holds internally. This 
structure keeps instances of your servlets around so that requests can be 
responded to more quickly.

I think its interesting that this PSPs reusable is set to 0. I wonder if 
that could be source of slow down. Can you tell me, are your PSPs always 0 
for reusable? What about .py's?

Are the Queues always empty?

The number of threads are determined in AppServer.config. The min is 5 and 
it grows to 20. If you are actually getting more than 20 _concurrent_ 
requests at a time, then you may experience a boost by increasing this 
number. That will depend on multiple factors probably including Webware, 
your op sys and your servlets. The best way would be to try it and see.

Are you already getting more than 20 concurrent users at a time?

I'm running Apache 1.3.19 and can't seem to get access to the HTTP_REFERER
value.  I know my browser is sending the Header, because I can pick it up in
PHP, but it doesn't show in Webware or in a Perl CGI script dumping all ENV
variables.

Anybody ever run into this problem?

Thanks,
Ben

Sorry for the false question, my problem was a combination of mixed up HTTP
requests with and without the referer, and a faulty httpd.conf.

So I'm now checking for the HTTP_REFERER environment variable in the
request().environ() dictionary and pulling it from there if it exists.

One also has to remember that referrer is spelled wrong in
the variable name.  I've been caught by that a couple times.

Dear Friend: 

AS SEEN ON NATIONAL TV: 

"Making over half million dollars every 4 to 5 months from your home 

for an investment of only $25 U.S. Dollars expense one 

time" THANKS TO THE COMPUTER AGE AND THE INTERNET! 

Before you say "Bull", please read the following. This is the letter 

you have been hearing about on the news lately. Due to the 

popularity of this letter on the Internet, a national weekly news 

program recently devoted an entire show to the investigation of 

this program described below, to see if it really can make people 

money. 

The show also investigated whether or not the program was legal. Their 

findings proved once and for all that there are "absolutely NO Laws 

prohibiting the participation in the program and if people can follow 

the simple instructions, they are bound to make some mega bucks with 

only $25 out of pocket cost". 

DUE TO THE RECENT INCREASE OF POPULARITY & RESPECT 

THIS PROGRAM HAS ATTAINED, IT IS CURRENTLY WORKING 

BETTER THAN EVER. 

This is what one had to say: 

"Thanks to this profitable opportunity. I was approached many times 

before but each time I passed on it. I am so glad 

I finally joined just to see what one could expect in return for the 

minimal effort and money required. To my astonishment, I 

received total $ 610,470.00 in 21 weeks, with money still coming in". 

Pam Hedland, Fort Lee, New Jersey. 

------------------------------------------------------------------------- 

Here is another testimonial: 

"This program has been around for a long time but I never believed in it. 

But one day when I received this again in 

the mail I decided to gamble my $25 on it. I followed the 

simple instructions and walaa ..... 3 weeks later the money 

started to come in. First month I only made $240.00 but 

the next 2 months after that I made a total of $290,000.00. 

So far, in the past 8 months by re-entering the program, I 

have made over $710,000.00 and I am playing it again. 

The key to success in this program is to follow the simple 

steps and NOT change anything." 

More testimonials later but first, 

*** PRINT THIS NOW FOR YOUR FUTURE REFERENCE *** 

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ 

If you would like to make at least $500,000 every 4 to 5 months 

easily and comfortably, please read the following...THEN READ 

IT AGAIN and AGAIN!!! 

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ 

FOLLOW THE SIMPLE INSTRUCTION BELOW AND YOUR 

FINANCIAL DREAMS WILL COME TRUE, GUARANTEED! 

INSTRUCTIONS: 

**** Order all 5 reports shown on the list below. 

**** For each report, send $5 CASH, THE NAME & NUMBER OF 

THE REPORT YOU ARE ORDERING and YOUR E-MAIL ADDRESS 

to the person whose name appears ON THAT LIST next to the report. 

MAKE SURE YOUR RETURN ADDRESS IS ON YOUR ENVELOPE 

TOP LEFT CORNER in case of any mail problems. 

**** When you place your order, make sure you order each of the 5 

reports. You will need all 5 reports so that you can save them on 

your computer and resell them. YOUR TOTAL COST $5 X 5 = $25.00. 

**** Within a few days you will receive, vie e-mail, each of the 5 

reports from these 5 different individuals. Save them on your 

computer so they will be accessible for you to send to the 1,000's 

of people who will order them from you. Also make a floppy of these 

reports and keep it on your desk in case something happen to your 

computer. 

****. IMPORTANT -DO NOT alter the names of the people who are 

listed next to each report, or their sequence on the list, in 

any way other than what is instructed below in step '' 1 through 

6 '' or you will loose out on majority of your profits. Once you 

understand the way this works, you will also see how it does not 

work if you change it. 

Remember, this method has been tested, and if you alter, it 

will NOT work!!! People have tried to put their friends/relatives 

names on all five thinking they could get all the money. But it 

does not work this way. Believe us, we all have tried to be greedy 

and then nothing happened. 

So Do Not try to change anything other than what is instructed. 

Because if you do, it will not work for you. Remember, honesty 

reaps the reward!!! 

1.. After you have ordered all 5 reports, take this advertisement 

and REMOVE the name & address of the person in REPORT # 5. This 

person has made it through the cycle and is no doubt counting 

their fortune. 

2.... Move the name & address in REPORT #4 down TO REPORT #5. 

3.... Move the name & address in REPORT #3 down TO REPORT #4. 

4.... Move the name & address in REPORT #2 down TO REPORT #3. 

5.... Move the name & address in REPORT #1 down TO REPORT #2 

6.... Insert YOUR name & address in the REPORT #1 Position. 

PLEASE MAKE SURE you copy every name & address 

ACCURATELY! 

================================================= 

Take this entire letter, with the modified list of names, and save 

it on your computer. DO NOT MAKE ANY OTHER CHANGES. 

Save this on a disk as well just in case if you loose any data. 

To assist you with marketing your business on the Internet, the 

5 reports you purchase will provide you with invaluable 

marketing information which includes how to send bulk e-mails 

legally, where to find thousands of free classified ads and much 

more. 

There are 2 Primary methods to get this venture going: 

METHOD # 1 : BY SENDING BULK E-MAIL LEGALLY 

============================================ 

let's say that you decide to start small, just to see how it 

goes, and we will assume You and those involved send out only 

5,000 e-mails each. Let's also assume that the mailing receive only 

a 0.2% response (the response could be much better but lets just 

say it is only 0.2% . Also many people will send out hundreds of 

thousands e-mails instead of only 5,000 each). 

Continuing with this example, you send out only 5,000 e-mails. 

With a 0.2% response, that is only 10 orders for report #1. 

Those 10 people responded by sending out 5,000 e-mail 

each for a total of 50,000. Out of those 50,000 e-mails only 

0.2% responded with orders. That's = 100 people responded 

and ordered Report #2. Those 100 people mail out 5,000 

e-mails each for a total of 500,000 e-mails. The 0.2% response 

to that is 1000 orders for Report #3. Those 1000 people send 

out 5,000 e-mails each for a total of 5 million e-mails sent out. 

The 0.2% response to that is 10,000 orders for Report #4. 

Those 10,000 people send out 5,000 e-mails each for a total of 

50,000,000 (50 million) e-mails. The 0.2% response to that is 

100,000 orders for Report # 5. 

THAT'S 100,000 ORDERS TIMES $5 EACH = $500,000.00 (half million). 

Your total income in this example is: 

1..... $50+ 

2..... $500+ 

3..... $5,000+ 

4..... $50,000+ 

5..... $500,000.........Grand Total = $555,550.00 

NUMBERS DO NOT LIE. GET A PENCIL & PAPER AND FIGURE 

OUT THE WORST POSSIBLE RESPONSES AND NO MATTER 

HOW YOU CALCULATE IT, YOU WILL STILL MAKE A LOT OF 

MONEY! 

------------------------------------------------------------------------ 

REMEMBER FRIEND, THIS IS ASSUMING ONLY 10 PEOPLE 

ORDERING OUT OF 5,000 YOU MAILED TO. Dare to think for 

a moment what would happen if everyone, or half or even one 4thof 

those people mailed 100,000 e-mails each or more? There are 

over 150 million people on the Internet worldwide and counting. 

Believe me, many people will do just that, and more! 

METHOD #2 : BY PLACING FREE ADS ON THE INTERNET 

=================================================== 

Advertising on the net is very very inexpensive and there are 

hundreds of FREE places to advertise. Placing a lot of free ads 

on the Internet will easily get a larger response. We strongly 

suggest you start with Method # 1 and add METHOD #2 as you go 

along. 

For every $5 you receive, all you must do is e-mail them the Report 

they ordered. That's it. Always provide same day service on all 

orders. This will guarantee that the e-mail they send out, with your 

name and address on it, will be prompt because they can not 

advertise until they receive the report. 

AVAILABLE REPORTS 

ORDER EACH REPORT BY ITS NUMBER & NAME ONLY. 

Notes: Always send $5 cash (U.S. CURRENCY) for each Report. 

Checks NOT accepted. Make sure the cash is concealed by wrapping 

it in at least 2 sheets of paper. On one of those sheets of paper, 

Write the NUMBER & the NAME of the Report you are ordering, 

YOUR E-MAIL ADDRESS and your name and postal address. 

PLACE YOUR ORDER FOR THESE REPORTS NOW:

Order Report # 5 from: 

Web Systems 

PO Box 1613 

Council Bluffs, IA 51502 

USA 

$$$$$$$$$ YOUR SUCCESS GUIDELINES $$$$$$$$$$$ 

Follow these guidelines to guarantee your success: 

If you do not receive at least 10 orders for Report #1 within 2 

weeks, continue sending e-mails until you do. 

After you have received 10 orders, 2 to 3 weeks after that 

you should receive 100 orders or more for REPORT #2. 

If you did not, continue advertising or sending e-mails until 

you do. 

Once you have received 100 or more orders for Report #2, 

YOU CAN RELAX, because the system is already working for 

you , and the cash will continue to roll in! 

THIS IS IMPORTANT TO REMEMBER: Every time your name is 

moved down on the list, you are placed in front of a different 

report. 

You can KEEP Track of your PROGRESS by watching which 

report people are ordering from you. IF YOU WANT TO GENERATE 

MORE INCOME SEND ANOTHER BATCH OF E-MAIL SAND 

START THE WHOLE PROCESS AGAIN. There is NO LIMIT to 

the income you can generate from this business!!!
____________________________________________________ 

FOLLOWING IS A NOTE FROM THE ORIGINATOR OF THIS 

PROGRAM: 

"You have just received information that can give you financial 

freedom for the rest of your life, with NO RISK and JUST A 

LITTLE BIT OF EFFORT. You can make more money in the 

next few weeks and months than you have ever imagined. 

Follow the program EXACTLY AS INSTRUCTED. Do Not change 

it in any way. It works exceedingly well as it is now. 

Remember to e-mail a copy of this exciting report after you 

have put your name and address in Report #1 and moved others to 

#2...........#5 as instructed above. One of the people you send 

this to may send out 100,000 or more e-mails and your name will be

more potential customers you will reach.

materials and opportunity to become financially independent. 

IT IS UP TO YOU NOW! 

************** MORETESTIMONIALS**************** 

"My name is Mitchell. My wife, Jody and I live in Chicago. 

I am an accountant with a major U.S. Corporation and I 

make pretty good money. When I received this program I grumbled 

to Jody about receiving "junk mail". I made fun of the whole 

thing, spouting my knowledge of the population and percentages 

involved. I "knew" it wouldn't work. Jody totally ignored my 

supposed intelligence and few days later she jumped in with both 

feet. I made merciless fun of her, and was ready to lay the old "I 

told you so" on her when the thing didn't work. Well, the laugh 

was on me! Within 3 weeks she had received 50 responses. Within the 

next 45 days she had received a total of $ 147,200.00 all cash! I 

was shocked. I have joined Jody in her "hobby."

"Not being the gambling type, it took me several weeks to 

make up my mind to participate in this plan. But conservative that 

I am, I decided that the initial investment was so little that 

there was just no way that I wouldn't get enough orders to at least 

get my money back. 

I was surprised when I found my medium size post office box crammed 

with orders. I made $319,210.00 in the first 12 weeks. The nice 

thing about this deal is that it does not matter where people live. 

There simply isn't a better investment with a faster return and so 

big." 

Dan Sondstrom, Alberta, Canada 

------------------------------------------------------------------------- 

"I had received this program before. I deleted it, but later I 

wondered if I should have given it a try. Of course, I had no idea 

who to contact to get another copy, so I had to wait until I was e- 

mailed again by someone else.........11 months passed then it 

luckily came again...... I did not delete this one! I made more 

than $490,000 on my first try and all the money came within 22 

weeks." 

Susan De Suza, New York, N.Y. 

----------------------------------------------------------------------- 

"It really is a great opportunity to make relatively easy money 

with little cost to you. I followed the simple instructions 

and within 10 days the money started to come in. My first 

month I made $ 20, 560.00 and by the end of third month my total 

cash count was $ 362,840.00. 

Life is beautiful, Thanx to Internet."

    running with 5 threads, from http://webware.sf.net.
    Normally each time a CGI script is invoked a lot happens
    on the server side, such as loading a perl or python
    interpreter, libraries, scripts, etc. and initializing
    same.  This does not happen in my case and the site
    response is lightning fast for dishing up dynamic content
    that is generated on the fly.  Webware even caches database
    connections so these are reused rather than re-created. 

 2. Every web page on the site is dynamically generated thanks
    to #1 above.  Only the home page is static as I cannot
    redirect my site host to use a cgi script for the home page.
    This is a *huge* reduction in site maintenence for me! 

 3. I dropped frames in favor of Cascading Style Sheets (CSS).
    Frame communication was becoming a lot of programming
    overhead and using DIVs in CSS is very easy besides looking
    nice.  All DIVs are hidden and only show upon menu select,
    which works extremely well.  The site now has no frames. 

 4. I added user entry for initial coefficient values. 

 5. I ensured the Levenberg-Marquardt solver cannot infinite loop
    on errors. 

 6. I added more 2D and 3D equations and equation categories. 

The next change I am now working on is to add an automatic equation
finder.  This would fit your data set to all functions and show the
user a list to choose from, based on fit statistics and the model
visualization plots.

Uhhhh, it probably is a nice example, if I could only understand what

Also:  OneShot is very useful for testing iterations, since it reloads 
everything for each hit.  

Stephen C. Waterbury  http://misspiggy.gsfc.nasa.gov/people/waterbug.html

OneShot.cgi is only for debugging when you are doing very active
development (and you don't want to restart the AppServer manually all
the time).

One thing that's been on my pie-in-the-sky list for a while:
  - a separate monitor process that communicates with the AppServer proce=

about what modules depencies should be monitored.  It watches the module=20
files and restarts the AppServer process if any changes are detected.

That should provide the best of both worlds: peformance and autoreloading=

Actually, I have other hopes for the monitor process as well:
 - scheduled restarts
 - triggered restarts on any number of user specified conditions
 - memory and cpu usage profiling/throttling
 - response time profiling

I gotta admit that my interest comes from the cool factor, rather than an=

I don't need *all* of that, but since I'm gonna be using Webware to
host web apps, for paying customers, on several boxes, across many
virtual domains, some of it would be nice.

It's that *kind* of stuff that would help make Webware seem more
attractive to the "enterprise" crowd, including ISPs. Having such a
monitoring solution would make selling Webware, as a consultant,
against the Java App Server easier, too. Nothing wrong with that.

And if I were a colo-host or big ISP, that kind of solution would
certainly make me more likely to consider allowing or providing
Webware for my customers.

Good ideas, Tavis.

Best,
Kendall Clark

Another aspect of this that I'm interested in:
 - being able to run scheduled functional  tests throughout the lifetime =
of a=20
webkit process and restart/report if the tests fail.  Once the basic=20
monitoring framework is setup it should be very easy to add a little wrap=
per=20
around Steve Purcell's httpsession.py and PyUnit.

One would hope.  Webware's great when you have control of your server, bu=
t=20
rather difficult to work with otherwise.

I first noticed this problem using IE-on-Windows.  I also see the problem in
several other client situations (these are all on Linux):
 
1. Using a Python script with urllib.py
2. Using wget
3. Using Netscape on Linux
 
Number 3 gives the most status information:  The error page displays, right
down to the uid/gid/etc. information, and the status bar states "12K read
(stalled)" and the "wait cursor" (the little wristwatch) displays until I
press Stop, at which point the status bar states "Document done."  At the
end of the page, then, is a horizontal rule, followed by "Transfer
interrupted!" in bold.
 
Now that I see what Netscape on Linux shows, there may be a clue.  Is there
supposed to be more error information AFTER the list of uid/gid/pid, etc.
The last think I see is 'getuid  500' (500 is the nobody user on my box).
If there's more information being collected, perhaps that's where the hang
is.

Cheers!

OK.  It doesn't happen here at work on Windows boxes, but I can try it this

Have you by any chance tried other clients beside IE-on-Windows?  I'll only

Subject: [Webware-discuss] WebKit Error traceback pages don't close their

When I get an error traceback page (it happens a lot, I make a lot of
mistakes), it seems like the HTTP connection doesn't get closed.  The
symptoms I see are that the traceback page loads, down to the end (I think),
where the IDs print, but the IE "globe" keeps spinning until I press the
Stop button on the browser.

When I request the /Examples/Error servlet via urllib in a Python script, it
hangs at the point of retrieving the page. If I press Ctrl-C, there's
nothing in the output file.

Any words of advice about what's going on and how I could fix it?  I'm
trying to write a cheesy automatic test for a servlet page that will simply
look for the presence of the traceback.  What I'm doing as a workaround is
assuming that no page will take more than 30 seconds to load (browser and
servlet on the same network), and handling an alarm if the timeout is
exceeded.

I appreciate any advice or pointers to information you can provide. 

Thanks.  By the way, the fancy traceback is a great boon for us--much easier
than finding and tailing a logfile. 

Cheers!

Hello everyone!!!

I'd like to use mod_webkit with Apache 1.3.2 on Windows 2000.
How do I compile the source on Windows? I don't have VS, and even if I did I
never used it before.
Has anyone compile it on windows successfully? If so could someone point me
to the right direction or maybe
even share the binary.

I'd also like to thank those of you that have created this frame work. It's
getting better and better.
The Python community have been craving for something like this.

Thanks very much

I thought that this would be of interest to some on this list. My

SPYCE - Server Python Pages
http://spyce.sourceforge.net

SPYCE is a drop-in Apache plugin that supports simple and efficient
Python-based dynamic HTML scripting. Those who like Python and are
familiar with JSP, or PHP, or ASP, should have a look at this engine. It
allows one to generate dynamic HTML content just as easily, using Python
for the dynamic parts.  Its modular design makes it very flexible and
extensible.  It can also be used as a command-line utility for HTML
pre-processing.

Version 1.1.8 released on 27 Jun 2002.

Your comments and suggestions are welcome.

My question was wrong, thouhgt. I'm looking for a compiled adapter. I have

binary of the .exe

I can compile the Isapi one, but I did not write it.  There used to be a 
memory leak issue.  I would recommend that you try the .exe for now and 
we can ask around about the isapi.  I used the .exe and it was fast 
enough for my app. Currently I use Apache2 and mod_webwkit on windows 
and its fast and stable.

Maybe the wkISAPI author can help.

Hi All,

I have several webkit servers (XP, Linux and Win2K) and in all of them I
get the following traceback every two hours or so (this one is from a
Win2K server):

None

Traceback (most recent call last):
  File ".\WebKit\SessionFileStore.py", line 78, in __setitem__
    self.encoder()(item, file)
  File "D:\Python22\Lib\copy_reg.py", line 58, in _reduce
    state = base(self)
TypeError: connect() argument 1 must be string, not Connection

What on earth is this?

TIA.

quick question:

I just updated both my python install (241->242) as well as updating
webware from the svn ( I know I should not have done both at the same
time) and when i tried to run webware (after running install.py again)
I received an error that in application.py at line 125 I could not do
float - none.  It appears to me that the Profiles.starttime is not
being set and so it defaults to none.  I added a line setting the
starttime to self._startTime which fixed the problem for me but I
thought I would pass the info to the group.  Has anyone else had this
problem?

Thanks for mentioning the problem; Jose. The error happens in 
AppServer.py, not Application.py, right?

I just noticed that this happens when you're using an old Launch script 
in your WorkDir with the new WebKit version installed. If you create a 
new WorkDir, everything is fine.

As a quick solution, create a new WorkDir with MakeAppWorkDir and copy 
the AppServer and Launch.py scripts to your old workdir. The new launch 
script has some improvements, e.g it is relocatable -- you can move the 
whole workdir around and it will still run.

Anyway I will make a fix today so that Webware stays compatible with old 
Launch scripts.

The SVN trunk is currently a bit unstable since I'm clearing out and 
improving the code in preparation of the 0.9 release. If there are any 
problems, please let me know and I will try to fix them.

-- Christoph

Ok, I've fixed that already. Just check out from SVN and it should work 
again. I still recommend using the new Launch script.
