Nabble - Active4D

[ANN] Active4D v5.0r4 released

2009-11-07T13:20:13Z

Greetings,

The latest version of Active4D v5, the ultimate web development
environment for 4D v11 SQL, is now available for immediate download.
This release brings important bug fixes, so all current v5 users
should upgrade as soon as possible.

The latest release can be found here:

https://www.aparajitaworld.com/site/products/Active4D/download.php

Active4D probably pushes the plugin SDK harder than any other plugin,
and I would like to give special thanks to Xavier Dal Moro and his
team at 4D for their hard work in fixing all of the 4D issues which
Active4D has uncovered.

Haven't tried Active4D yet? Looking forward to PHP integration in v12?

"Using Active4D has helped me move over smoothly to learning PHP and
other web-languages. You will recognize many of the same functions and
features that Aparajita has brilliantly brought back into the 4D
ecosphere." - Mehboob Alam

For those of you who want to put a (*cough*) real web server in front
of Active4D, check out cherokee. Looks pretty cool.

[ANN] Active4D v5.0MC2

2009-10-29T06:15:13Z

Greetings,

I am happy to announce the availability of the second (and hopefully
final) release candidate for Active4D v5, the ultimate web development
environment for 4D v11 SQL.

Here are the comments of just one of the many happy Active4D developers:

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

"Active4D is simply great.

If you've never programmed for the web before, there is a little bit
of a learning curve -- however, it's richly rewarded with the power
and elegance that's built into this product. Plus there's great
support on his mailing list, from Aparajita directly or many other
experts who are happy to help.

As Aparajita mentions in his promotional materials, the session
management alone is worth the cost.

The Active4D language and libraries are very rich -- yet, the big
attraction is that you can just write 4D code exactly like you always
have. No need to build a method in 4D (although you can do that and
call it from Active4D) -- just write the code directly into the web
page or library method.
This is much better for maintenance -- just update the web page rather
than 4D (which if you're running compiled in a client server
environment is not a simple task to do).

Again, it's really the way to go when web programming with 4D.

Very highly recommended -- you won't make a mistake by choosing this
software for your web projects!"

Installation instructions for db method On Web Connection

2009-10-28T21:37:15Z

Thought I'd post here before reporting it in the bug tracker.

Maybe I'm missing something, but following the 5.0mc1 instructions for
a4d installation to a new and existing database, I see no reference to
calling the A4D_OnWebConnection method from the database method On Web
Connection. I see the comment explaining what to do in the
A4D_OnWebConnectionmethod, but it is not in the docs (I don't think).

I knew what to do cause we're upgrading a db, but new users may be
confused as to why A4D doesn't work.

Did I miss something? Or should I report it to Mantis?

Thanks,

Michael Check

Yes, it only runs on that machine if Active4D is running on the machine.

I assume this process is running on the machine running Active4D. We
created a cron task in 4D that could call Active4D code. Can't
remember all the details, but our missing logic was that the cron task
was running on the server and Active4D was running on a 4d client (no
Active4D or web license on the server). Since we needed it for both 4D
and Active4D, we just gave up the Active4D side (guess we could have
used execute on client - but I'm not a 4D person). For the Active4D
stuff, we just created a cron task in Mac OS that would generate a
curl to a controller script.

Your library approach would probably simplify that process.

Thanks Aparajita,

I'm back to working with A4D next week so will have a look at this.

Sounds like a great feature...

periodic task library

2009-10-24T13:47:09Z

Hi,

I had the occasion to need periodic tasks for a project I'm working
on, and came up with a generic a4d.tasks library. Here is the current
design:

create(inMethodToExecute; inPeriodInMinutes {; inData {; inLimit}}) ->
longint
- inMethodToExecute must be a globally accessible Active4D library
method with the following signature:

method "myTask"($inId; $inAction; $ioData)
- inId is the task id
- inAction is "init", "exec", or "deinit"
- ioData is the data that was passed into 'create task'
- you may call 'delete($inId)' within this method to cause the task to
be deleted on the next run

- inPeriodInMinutes is how long between calls, >= 1. No guarantee the
task will be run that often, it is actually the minimum number of
minutes between calls, since the queue is only checked every 10 seconds
- inData if passed and non-zero must be a *global* collection, it will
be cleared with 'deep clear collection' when the task is deleted
- inLimit if passed is the number of times you want the task to be
executed, after which it will be removed, < 0 means unlimited

delete(inId)
- remove the task and deep clear its data
- if called from a currently running task, marks it for deletion on
the next run

dump
- Dumps the task list to the A4D console

I would like any comments or suggestions before I release it as part
of the Active4D standard libs. The task runner will be a 4D method
running in a separate process that calls a4d.tasks.execute every 10
seconds.

Typically in one of your libraries, you would do something like this:

method "__load__"
self{"mytask"} := a4d.tasks.create("mylib.mytaskHandler"; 1)
end method

method "__unload__"
ad4.tasks.delete(self{"mytask"})
end method

method "mytaskHandler"($id; $action; $data)
case of
:($action = "init")
// do some init

:($action = "exec")
// run my task

:($action = "deinit")
// cleanup
end case
end method

Re: Memory leaks

2009-10-19T09:28:39Z

Hello

With 4Dv10.5 and Active4D 5.0b4 until now, there are no more memory-
leaks!!!!
Aparajita, thank you very much for your super work.
Now the time will be gone, where the 4D eats and eats memory and crash
anywhere in the middle of anything.

It's a problem with 4D's built-in web server. The crash occurs before
the request even reaches Active4D.

Yes, that is definitely another alternative.

So is this a problem in 4D's built-in web server, or a but when that
server is used with Active4D handling requests from those browsers?

We use NTK in regular mode with Apache in front. Maybe NTK in SSL mode
would be another alternative? Is anyone here using NTK/SSL with Active4D?

I seem to remember hearing about this before, and reported it to 4D.
You can count on it never being fixed.

As Steve said, use apache (or nginx or lighttpd, etc.) in front of 4D.

Use Apache for SSL is one solution! I never could get the 4D SSL
component to work.

2009-10-17T11:36:55Z

Mac OS 10.5.7

4D 2004.8

A4D 4.5r1

There has been an ongoing problem crashing 4D in the SSL component, related

Has anyone found a way to solve this problem other than migrating to Windows
for the A4D server?

So the biggest problem did came from 4D and not from Active4D.

Simple json parse

2009-10-14T11:27:30Z

Here goes Steve again with another piece of hare-brained code. I have
a use for it, maybe someone else could use it.

Several weeks ago I asked about a json parse routine - something that
would convert json to a collection. I wrote one several years ago, but
since I don't use json with javascript, I'm not sure it had a use
outside of mine. I was also not very happy with the complexity of the
converted code.

My use of json is to serialize some form data and I didn't need every
possible type(text!). I had done the serialization before with tagged
text(xml) and collection or object tools blobs, but was looking for
something more generic and better than xml.

jsonParseSimple is an Active4D method that will convert a json object
to a collection. It's big limitation is that it will only handle
objects/collections and text arrays. Again, for me, that is not a
limitation - that's all I need. Code below and more meaningless
comments below that;

method "new array"($list)
// convert semi-colon delimited list to a text array
$cnt := split string($list;";";$chunks)
return($chunks)
end method

method "jsonParseSimple"($json)
/*given a json object,convert it to an Active4D collection*/
array text($re;0) // regex array
array text($rp;0) // replace array
// set the reqex array
$re{} := "|:\\s*{|" // object => convert :{ to ;new collection(
$re{} := "|:\\s*\\[|" // text array => convert :[ to ;new array
( -- local method see above
$re{} := "|\\]|" // end text array => convert ] to )
$re{} := "|}|" // end object => convert } to )
$re{} := "|[:,]|" // replace comma and colon with semi-colon
$re{} := "|{|" // replace begining object with new collection()
$re{} := "|n\$\$|" // replace empty collection convert n() to new n
//set the replacement array
$rp{} := ";new collection("
$rp{} := ";new array('"
$rp{} := "')"
$rp{} := ")"
$rp{} := ";"
$rp{} := "new collection("
$rp{} := "n"
regex replace($re; $json; $rp; $results)
$collection := execute("return ("+ $results+ ")")
return($collection)
end method
//test
$json := '{"post":{"answers":{"1":"2","10":"19","2":
["11","12"],"74":false,"75":["555","1212"],"76":
["277
","278
","279"],"77":"283","78":"285","79":"286","9":"18"},"answers_text":
{"10":"dfd","74":"","76":["one","two","three"],"78":"fox back
lazy","79":"3.1415"},"assessment_id":"1","failed":
[],"maxValue":"32","maxValueWeighted":"44","other_answers":
{},"totalScore":29,"totalScoreWeighted":33}}'

$myCollection := jsonParseSimple($json)
a4d.debug.dump collection($myCollection)

-----Meaningless comments ----

Several years ago I was pressured into developing an on-line job
application for our customers. This happened when our 4D structure was
in the middle of a major change and I could not get the structure
changed. I had a couple blob and text fields available to me, so I
wrote the application and stored the data in the blobs. This was
supposed to be temporary because someone else was going to develop a
RoR application.

The RoR application never made it. After I retired, I experiment with
the RoR application and got it working using some tables. It turns out
that the major part of the job application process is asking a bunch
of multiple choice question: "How many years of welding experience do
you have?". Since those questions were different for every job, I
still ended up using json to store the raw input data . Only the
Assessments(questions and answers) and the scoring results use a table
structure.

Since they are still not ready to convert to RoR, I replicated my
experiment in Active4D. The above json object is an example of what I
created using the form data and some results from processing the data
(how they scored on the assessment, etc). It is just a bunch of ids
pointing to the questions and answers. In case you have not noticed,
this will serialize nested collections, something "collection to blob"
will not do.

Hi,

at last years summit someone <sig!> asked me, if I use v11 in
production. I said "No, I'm waiting for a .5 release, as always." I
got bashed around with the remarks "There will be no .5, v12 will come
early." I should have made a bet on it... :))

Memory leaks

2009-10-13T07:10:41Z

Hi,

I am now doing extensive leak testing of Active4D. While there are
some leaks in Active4D, unfortunately I am finding far more leaks in
4D. I am informing them of the leaks and hopefully they will be fixed
in the next hotfix release.

I probably won't release a v5.0b4 until this weekend, I would like to
finish the leak testing before I do.

Kind regards,

Re: Active 4D and Wakanda

Currently, v12 will not be able to execute PHP in a Webserver context.
This is very pity for me, but good for you, now.

But, how many 4D programmers know PHP? I think 80 percent of 4D
developers had not worked with XML or SVG...

ScreenFlow for the screen recording, Audio Hijack Pro for the sound

There was one tantalizing detail about Wakanda.. the "server" is
faceless, so it may also be available for Linux and "cloud"-platforms...

and the Wakanda data-engine will have replication/synchronization
capabilities with 4Dv11.
