Re: Pluggers Software releases NTK Plugin 3.0

[Paul Dennis]

Blimey, that is a major update Rob, Framework looks very interesting. For
anyone else trying the demo its v13 on port 8080. With the web demo I
couldnt get past the web login page or create account. Bit more info on demo
would be useful.
Cheers
Paul

Re: Date Question...

[Keisuke Miyako]

I guess it just affirms the point that date constants are too ambiguous and not 
worth your while.

$dateA:=!2016-12-15!
$yearA:=Year of($dateA)  //2016

$dateB:=!16-12-15!
$yearB:=Year of($dateB)  //16?
ASSERT($dateA=$dateB)

an error handler is needed because Get pointer will throw an error if the 
string doesn't evaluate as a variable.

e.g. Get pointer("type")

Re: Follow Up Request: Automatic Variable Assignment and Web Get Variables - Bad usage of pointer or pointer to an unknown variable

[David Adams]

> Since OB Is Defined is case sensitive I cannot use it unless I spend days

I haven't followed this thread and just have a minute, but thought I'd
mention that a standard cheat for defeating unwanted case-sensitivity in
comparisons it to convert everything to lower or uppercase before
comparing. 4D variable names are not case-sensitive, so just set the string
of the name to all to lower or upper before storing the names in your
object. Same with the incoming values that you want to check, set them to
the matching case before comparison with the values in the object.

Follow Up Request: Automatic Variable Assignment and Web Get Variables - Bad usage of pointer or pointer to an unknown variable

[Michael McCall]

In brief and as a reminder, I need a way to quickly assign values to variables 
received from a web page. The problem I have is that if a field submitted on a 
web page does not exist it produces a  runtime error messages in a compiled 
data base indicating a bad usage of a pointer. The process stops until continue 
or abort is selected. 

I want a way to just ignore any instances where the variable does not exist in 
the data base.  Lee's suggestion of putting my 25,000 variables in an object 
and using OB Is Defined looked like a fast easy solution. Unfortunately I was 
sloppy over the last 25 years it turns out and I have not consistently made use 
of case convention in my variable names. Since OB Is Defined is case sensitive 
I cannot use it unless I spend days cleaning up my code. I will put that on the 
list for the future, but, in the meantime, does anyone have any other quick 
solutions? 

Keisuke made a reference to using Not(Nil( $p))) and Type($p->) following Get 
pointer. I played with that but can't quite see how that would work. In essence 
I would just like to bypass or ignore any situations where the 
arr_Web_Field_Name is not actually a defined variable name so I don't get the 
runtime error messages related to bad usage of a pointer which in turn halts 
the process until I click the continue button.  

Any suggestions? Hopefully I'm just missing something obvious and simple here.

WEB GET VARIABLES(arr_Web_Field_Name;arr_Web_Field_Value)
For ($i;1;Size of array(arr_Web_Field_Name))
$p:=Get pointer(arr_Web_Field_Name{$i})
$p->:=arr_Web_Field_Value{$i}
End for


Thanks again,
Mike McCall





ORIGINAL POST FROM NOVEMBER 9, 2016: 

Thanks in advance for any assistance,

This is probably something I should know and clearly something I could do 
differently but for now I'm hoping for an easy solution.

I believe 4D is moving away from the Automatic Variable Assignment option when 
using a browser to access a 4D enabled Web server. As they do that I believe 
the replacement approach is to use Web Get Variables. Because we have a silly 
number of variables (i.e., 20,000) which could be called from any given web 
page we'd like use something similar to the code below to assign the values 
received using Web Get Variables to their corresponding and existing variables 
using pointers. That would allow us to move away from the Automatic variable 
assignment without a major rewrite to our code.

In an uncompiled application the code works fine. 

In a compiled application it works fine as well unless someone were to 
maliciously or somehow inadvertently submit a web page with a field name which 
was not defined in our application. In brief if they modified an html form to 
submit to our application and added a non-existent field, then a -20010 error - 
Bad usage of pointer or pointer to an unknown variable message would be 
generated and the connection would hang until we clicked OK on the message on 
the server.

Is there any way we could avoid this from happening? We were hopeful that using 
"undefined" would help but that doesn't work in a compiled database. 

Aside from a major rewrite of how we handle the fields from a form statement 
does anyone know how we could just ignore unknown field names o handle them 
without the error message being generated in a compiled database?

RE: Saving a backup to a network share when running as a service

[Joshua Hunter]

Thanks Tom & Bill for the replies.

It looks like the issue is that when selecting a backup location 4D uses the 
mapped drive letter. When running as a service you cannot used mapped drives, 
but need to use the full UNC path. That doesn't seem to be possible with 4D.

We have recommended exactly what Tom suggests: backup locally and copy to 
another location as separate operations.

Thanks,

Joshua

Date Question...

[Dennis, Neil]

The 4D manual says this about dates:
Date: 1/1/100 to 12/31/32767

So what is this date constant?
$d:=!16-12-15!

FYI - It is not the same as !2016-12-15!

Re: v12+ parsing text [summary]

[Chip Scheide]

I'm not working with arrays (being passed)
but a single text variable.

x_Parse:=ax_File_Contents{$Current_File_Text_Block}
then x_Parse is worked on/with

So a method call looks like this:
utl_text_Fast_Parse(->x_Parse;$Delimeter_Count;$Delimeter)


BUT if I were working with the array directly, I would pass a pointer 
to the element
utl_text_Fast_Parse(-> 
ax_File_Contents{$Current_File_Text_Block};$Delimeter_Count;$Delimeter)

Re: Saving a backup to a network share when running as a service

I would get to the point where things would run for a few days, then break, for 
reasons I couldn’t explain. Only thinking was that of all the permissions

service. They want to direct their backup to a network location. This works 
when they run the application interactively, but not when they run it as a 
service.

I've let them know that backing up locally is preferred for a number of 
reasons, but they still want to backup to the network location.  I've tried 
providing the same user credentials to the service that we use to run 
interactively without any luck.

Has anyone had success with this?

Thanks,
Joshua

Re: v12+ parsing text [summary]

[Chip Scheide]

I am using a text array (only 1 element)
The array is created on import of the text from the disk file and is 
NOT resized (except to clear) after this. The element(s) of the array 
are filled via Receive Packet(Doc;Array_Element;1,500,000,000)

Original Issue - I tired to import a large (50meg) document -- time to 
import was excessive.
The 50 meg file I was trying to import failed to complete after running 
over night (~16 hours).

Resolutions:
- New text parsing code -- this code keeps track of how much of the 
text has been processed via longints, and does NOT manipulate the text 
(being parsed) directly, only getting substrings from it, and never 
changing it's size.
- New routine to replace/wrap substring
- Pass text to be parsed to various methods VIA POINTER*

My original code, truncated the source text to the next character after 
the text to Find (delimiter)
This, added SERIOUS time overhead.

The import process includes creating slightly more then 332,000 records
My new code imports the same 50 megs file (interpretedly) in about 7 
minutes.
My new code imports the same 50 meg file (compiled) in just over 1 
minute.

4D v12 (stand alone), OSX 10.6.8, Mac Mini 8gb RAM, 2.4ghz Core 2 duo, 
spinning metal hard drive


* using the new code, and passing the Source text (to be parsed) as a 
text parameter my new import routine took about an hour to complete.

Re: Server Backup when running as a Service

[Bill Weale]

Can you check (manually or by code) if the target volume is mounted when the 
backup is run? I had so many problems with this at one site that we gave up 
trying.

A more serious problem, imo, is not having a reliable place to maintain the log 
file…

Re: v12+ parsing text

[Alan Chan]

I can't agree more. Array was not mentioned in Chip's original post.

Always decide size of array before hand by evaluating the source using position 
to count stop char or using \ and % to calculate if length of element is 
deciding factor.

Re: v15.3 seems to be crashing on MACOS 10.12.1 & the new MBP

[Spencer Hinsdale]

if you're bored, try v16 beta or 15R5.  i think these avoid some problems by 
being carbon free.  i would be curious to know if they work with the bad build.

i have been running 15.3 with the good build and it's awesome.  just saying. :)

What happens with manual backup? Permissions? what type of volume. Mounted
or local?

Re: v15.3 seems to be crashing on MACOS 10.12.1 & the new MBP

[cswirth]

Douglas,

Rolling back to 15.2 may not work either. We are having issues with Sierra
build 16B2657 and 4D v15.2. Build 16B2555 works fine.

Re: v15.3 seems to be crashing on MACOS 10.12.1 & the new MBP

[cswirth]

Kirk,

Same problem here with a MacBook Air recently upgraded to Sierra. The issue
for us is that 4D crashes anytime a 4D Write area is touched. I am running
Sierra on an iMac with no issues and thought it may be related to the
laptop, however see the release notes for 15.3, what they state is
consistent with our experience. Running 4D on the older build of Sierra
10.12.1 is fine, not so on the more recent build.

Regards,
Scott Wirth

Kirk:

I was just reading the release notes on 15.3 
and I think you're wise to roll back to 15.2.

For 15.3, they're distinguishing between two different builds of 10.12.1.
They conclude "As a consequence, we have decided to postpone the macOS
Sierra certification until the final version of 10.12.2 has been shipped by
Apple."

Server Backup when running as a Service

[Cheryl Michels]

This seems simple so I must be missing something very basic.  We have a 
merged/built server application.  Customer wants to run it as a Service and 
backup the data to a drive other than the one that it is currently installed 
on.  The backups are not getting written.  There is no error.  They simply 
don't write.  If the backup is configured to write to the same drive that 
Server is on, then the backup writes without error.

Hi Chuck,

No code changing. Just adding a few refresh buttons at the moment to see if 
they make any difference.

As to changing window type we’ll see after I get some feedback from them.

Appreciate,
John...

v15.3 seems to be crashing on MACOS 10.12.1 & the new MBP

[Kirk Brooks]

Just unboxed a new MBP. And it's pretty fricking awesome! Just saying.

After about 45 mins I had it setup to the point I was ready to download 4D
give it a spin. Just in time for the brand new 15.3 update to boot. Sadly
things are not going well. 4D 15.3 crashes on start up.

I use Little Snitch to monitor IO. I noticed the 4D login screen appears as
expected while Little Snitch is blocking the network connection. As soon as
I authorize 4D it crashes. I turned off Little Snitch on the chance that
was somehow creating the problem. In this case 4D just crashes immediately.

I'll try installing v15.2 later.

Relevant part of the crash log follows:

Also it might be creation of array. Remember that every time 4D resizes an
array especially bigger, it looks for a block of memory that can hold it
all. In effect copying array over and over

Think of it this way

Array text($Somtext;0)
insert element($Somtext;size of array(Somtext)+1)
$Somtext{size of array(Somtext)}:="bkjbkjbkb" `copy one


insert element($Somtext;size of array(Somtext)+1)
$Somtext{size of array(Somtext)}:="bkjbkjbkb" `copy two

etc each looking for larger chunks of continuos memory

Regards

Chuck

third reason:
 [artwork]
 name
 author
 description
 photo (external storage)
LOAD RECORD([artwork])  //photo is loaded too   :-(

Another (bad?) reason is that it took me a while to understand the way 4D 
organizes the folders. 

I prefer doing it myself. 
 [artwork]
 name
 author
 description
 photo_ID
The path is made from photo_ID. 

If I plan to move documents one day "somewhere else" (cloud or something), 
things will be easier I suppose.

I understand that you keep the whole document in an array, right?
If so, I know that splitting a huge text in a text array makes it much easier 
to manipulate, but, at the end, 4D memory is the same. In my example of 6,6Gb 
file, it was not a solution. 

That said, I read your 1st message too fast (as usual). Seems your document is 
not so huge (billion is not used in french, I always mistake)

For smaller documents, I used in v12 a wrapper for 'document to text':

***
 //FS_documentToText (path_t {;charSet_t {;lineEnd_l) -> txt
C_TEXT($0;$1)
$doc_t:=$1
$charSet_t:="utf-8"
If ($params_l>1)
$charSet_t:=$2
End if
DOCUMENT TO BLOB($doc_t;$data_x)
$0:=Convert to text($data_x;$charSet_t)
***

Another thing I read too fast is about using position/substring/truncating. 
Since v11 this can be avoided with the 2 Position parameters (that changed my 
life):
- start from
- * (at end)

The classical "delimited text to array" becomes quite simple:


And reading a csv file too:
***
$data_t:=FS_documentToText (path_t;"utf-8")
array text($line_at;0)
explode(->$line_at;$data_t;"\r")
array text(field_at;0)
For($i;1;size of array($line_at))
 explode(->field_at;$line_at{$i};",")
end for
***

Re: encapsulate HTML

[Peter Schumacher]

Hi Ferdinando,

Nope, will not work.

Reason: You want to execute a html form. On a web page you need to specify a 
form processor with . An email client can't do this - and 
shouldn't do it for security reasons.

Greetings,

 We are having issues where the scrollbars in included forms and lisboxes

 Has anyone else seen this?

David,
I have received the email.
Tomorrow i do some tests.

I suppose that you use the web server part of 4D for do this, one possible 
problem is that in the my application is one server that are not opened on 
Internet.

Thanks
Ferdinando

I’m going to set you up an Account record in my customer’s system and send you 
the link.
 
I can also send you the Active4D web scripts that display and read the posted 
result.
 
Is that OK?

To receive the answers you’ll need 4D to access the submitted form variables. 
4D will receive the posted form using a web server (4D native, Active4D, NTK). 
You’ll include a hidden input value in the form with a UUID as Lee Hinde said. 
This is your key to match to a record to store the form input values.
 
Your “submit” button will post the form to your 4D web server.
 
You’ll have to learn a little HTML, and you’ll learn how to read the results of 
the “post”ed form.
 
This kind of thing is very easy for 4D types that have been working with web 
for a while.
 
Another way:
I just wrote an email html formed in 4D Write, with a link and a UUID that when 
the user clicks on the email link, they go to a form published by 4D, which 
they complete and save. The UUID makes it possible to match the email recipient 
to record in the database. The embedded URL in the 4D Write document, converted 
to HTML, has “#” in it that I replace string to the UUID value.

I have not done this in an email, but you can try putting an iFrame in your 
html email that references a form delivered by your 4D system.
 
Hope that helps!

Hi All,
 
Someone know how is possible to encapsulate one questionary in HTML in email
body, and to receive the answer's and take the answers in 4D?
 
Thanks
Ferdinando

If MSC says it’s fine, I’m sure it’s fine. There is a lot of whitespace in a 
data file, which compression gets rid of. A 2GB text field of all spaces would 
probably compress to a few bytes, but doesn’t have any space available from 
4D’s point of view.

Try compacting anyways and see what the size difference is - it may not be as 
much as you think.

Ben Kershaw

Re: v12+ parsing text

Hi Chip, 
you can't use 'document to text' (since v13 only) and I doubt about using 
'document to blob' to "load at once" such a big document. For my own, I use 
load at once when the document is small enough in 4D 32bits versions (small 
means <500Mb). 

Schematically:


$trailing_t:=""
ARRAY TEXT($line_at;0)
$sizePacket_l:=10  //to be tuned
USE CHARACTER SET("UTF-8";0)  //example
$ref_h:=Open document("";"")
if(ok=1)
  repeat
RECEIVE PACKET($ref_h;$packet_t;$sizePacket_l)
$trailing_t:=$trailing_t+$packet_t
Explode(->$line_at;"\r")  //CR delimited text to array
$numberOfLines_l:=Size of array($line_at)
$trailing_t:=$line_at{$numberOfLines_l}  //keep last line aside
For($i_l;1;$numberOfLines_l-1)
  //do something with $line_at{$i_l}
End for
  until(ok=0)
//don't forget last piece here  ;-)
  CLOSE DOCUMENT($ref_h)
end if
USE CHARACTER SET(*;0)


I've used this to import a 6.6 Gbytes text document 2 years ago, really fast 
(of course SSD disk is better). What happens in the "For" is another story. 

Note 1
avoid using a stop char in the reading process, it is what makes it slow. 

Note 2 
if the document only contains "low ascii chars" (one byte=one char), you can:
- remove 'USE CHARACTER SET'
- read blob instead of text in 'RECEIVE PACKET'
- convert each packet with blob to text
Did not test, but I think it's faster.

Re: 4GB Data Compresses to 80 MB

[Koen Van Hooreweghe]

Hi Sujit,

Compacting is not the same as compressing (aka zipping).
4D datafiles have always had a big compression rate. But so do text files. Just 
tested a small file which is 100kB and was zipped to 3,5kB

4GB Data Compresses to 80 MB

[Sujit Shah]

I have this 4GB Datafile which zips to 80MB. However when I run MSC it
tells me the data file does not need to be compacted.

I am wondering if there are potential issues with this data file?

At the moment it is running fine.
