Re: IP Calculator Final Version

[Bob Sneidar]

Hi Mike. May have spoke too soon. Apparently I need to check for empty octets 
because apparently this will only sometimes get caught in the error checking. 
Now I am going to have to *really* go through this. However, if proper values 
are provided the function works as expected so I would let it stand for now and 
I can provide an updated version for the next revision if there is one.

Re: IP Calculator Final Version

[Bob Sneidar]

So now I modify the condition to look like this:

   set the itemdelimiter to "."
   repeat for each item theOctet in theIPAddress
  if theOctet is empty or theOctet < 0 or theOctet > 255 then
 return "ERROR: Each IP Address octet must be a number between 0 and 
255. " & \
   "(ipaddress = " & theIPAddress & ")"
  end if
   end repeat

Note the check for the octet being empty. NOW it fails the condition every 
time. What this means is that sometimes the engine thinks empty is less than 0 
and sometimes it does not. Otherwise it means that sometimes an item which 
ought to be empty is not, and sometimes it is. Is this scaring anyone besides 
me? I am calling the function containing this code from the message box. I 
could go through the process of running it from a button but frankly having 
been able to force the engine to check for empty, I have solved the problem for 
now. But if anyone comes across something similar, it isn’t a gremlin. Or is 
it…???

Should return an error on the third pass. It does not. Even though empty is in

I stepped through the code, and at first it passed, but then I put in a 
statement just before the condition:

 put theOctet is empty

On the third pass it put true into the message box then FAILED THE TEST! 
Subsequent calls to the function continued to fail! Then I stopped stepping and 
recompiled the script and saved it. IT STARTED PASSING AGAIN!

This is some crazy crap! The same code should not be behaving differently 
depending on whether or not I am stepping or not.

Re: Unicode

[Peter Haworth]

Well I guess I spoke too soon :-)  When I said I had things working, I
meant I could successfully get data from a UTF8 database and display it
correctly.

I'm now trying to get input from field controls and get it into the
database.  I found a lorem ipsum generator that would create text in
various languages to I got some Russian text from it and pasted it into an
LC field.

In my handler, I need to put the contents of the field into a variable and
then hand it off from there to an INSERT statement. I've tried every
combination of unicodeText, uniencode, unidecode, or none of the above to
get the correct value into the variable but it either ends up as question
marks or something that looks nothing like the characters in the field.

This is all with pre 7.0.  I think I'm beginning to understand why 7.0 is a
lot better to use than pre 7.0 when heavy unicode handling is needed!

But in the meantime, how should I be handling the above situation in pre
7.0?

Re: IP Calculator Final Version

[Bob Sneidar]

Oh thanks Alex I will check for those. I though they would be covered in the 
part that checks that each octet is a number between 0 and 255.

As far as the CIDR depth, it is true that technically you can have a CIDR of 
32, but it is not a network that can be used. That would leave no usable 
addresses, and the subnet and broadcast addresses would not be assignable. A 
CIDR of 31 has 2 addresses, neither of them usable by a node, as they would 
have to be the subnet address and the broadcast address.

The highest CIDR that has any node assignable addresses is 30. That has only 2 
usable addresses, and is typically used as the WAN subnet for a single IP 
router, the other being the gateway address.

A CIDR of 0 has no subnet mask, and therefore cannot be used except for a 
multicast network where everything is a node, there is no universal broadcast 
address and no routing is possible.

For the sake of accuracy, I will expand the range to 0 to 32. It will be up to 
the calling function to then determine if their subnet is usable.

Also, not sure why you limit CIDRDepth to between 1 and 30. RFC 4632

enough, as is default route.

Offset and Binary Data

[Alejandro Tejada]

Hi Mike,

After running your script, using Livecode 7.0.1
under Windows my result is 4,10

Maybe, this could help.
Add this line before getting offset:
set the casesensitive to true

to read in this way:

on mouseUp
put numtochar(255) & numtochar(216) into tStart
-- in Hexadecimal: FFD8 = SOI(Start of jpeg image)
put numtochar(255) & numtochar(217) into tEnd
-- in Hexadecimal: FFD9 = EOI(End of jpeg image)

put "AAA" & tStart & "DATA"& tEnd & "BBB" into temp1

set the casesensitive to true

put offset(tStart,temp1) into tThumbstart
put offset(tEnd,temp1) into tThumbEnd
answer "Start:" && tThumbstart & cr & "End:" && tThumbEnd
end mouseUp

extracting the thumbnail from digital photos?

[Alejandro Tejada]

Hi,

This script works in LiveCode 7.0.1
under Windows:

(Notice that I am using byte instead of char
as recommended in release notes and,
unlike Ubuntu, I have to set the casesensitive
to true to make it work)

First, download this 8 MB image that contains
two thumbnails (320x240 and 160x120):
(this link should be in a single line)

http://216.18.212.226/PRODS/fuji-x100t/FULLRES/X100ThSLI00100NR2D.JPG

Create a stack and put this script
in a button:

on mouseUp
   local temp
   answer file "Select JPEG image with EXIF thumbnail data"
   put it into temp
   open file temp for binary read
   read from file temp for 10
   put it into temp1
   close file temp

   put numtobyte(255) & numtobyte(216) into tStart
   -- in Hexadecimal: FFD8 = SOI(Start of jpeg image)
   put numtobyte(255) & numtobyte(217) into tEnd
   -- in Hexadecimal: FFD9 = EOI(End of jpeg image)

   delete byte 1 to 2 of temp1
   -- delete JPEG SOI (Start of jpeg image)
   if byte -2 to -1 of temp1 = tEnd then delete byte -2 to -1 of temp1
   -- delete JPEG EOI(End of jpeg image)

   set the casesensitive to true


repeat until offset(tEnd,temp1) = 0

  -- repeat until offset(tStart,temp1) = 0

   put offset(tStart,temp1) into tThumbstart
   put offset(tEnd,temp1) into tThumbEnd

   put byte tThumbstart to (tThumbEnd + 1) of temp1 into tJPGThumb

   delete byte 1 to (tThumbEnd + 1) of temp1

   if tJPGThumb is not empty
   then
  create img
  set the text of it to tJPGThumb
   else
  answer "No JPEG Thumbnails in this image"
   end if

   end repeat
end mouseUp

Not at webfaction where I have various versions of LC Server running as 
as cgi via a Caudium server which in turn runs behind nginx (and maybe 
Apache, I'm not sure if they've left the Apache layer in for the 
deployment of webapps, since putting nginx up front, and am too lazy to 
look it up because it still works so why should I care :D). Request 
handling is fractionally slower since LC 6.5 but the discernable delay 
doesn't seem to have increased here for LC 7. I've already reported that 
script handling is 3 to 4 times slower in LC 7, but that's a different 
issue.

Exactly - this is actually under two different bug reports now, #14437

able to 'see' Quicktime movies, even in 6.5.2, when assigning a new

the team at Livecode looks into these bugs.

semi-OT: TestFlight.com beta testing closing

[Chris Sheffield]

Just thought I’d throw this out there. Sounds like Apple is killing the 
TestFlight.com  beta testing site in favor of their 
newer TestFlight service.  
http://www.idownloadblog.com/2015/01/26/apple-closing-old-beta-testing-test-flight/
 


Kind of cruddy, imo. Especially because Apple’s new version of the service only 
supports devices running iOS 8+, which means no more testing apps on older 
devices, or even on newer devices running older versions of iOS. Their 
TestFlight app won’t even install unless iOS 8 is installed on the device. In 
the education market, we need to be able to test different configurations. I 
was kind of hoping they would leave this service running a bit longer. We may 
have to look for something else.

Does anyone know of other beta testing services that work similar to TestFlight?

Also, the last time I checked into using TestFlight in iTunes Connect, I could 
not get a LiveCode-built app to work correctly. I kept getting a warning about 
missing entitlements. Does anyone know if this is fixed yet? I haven’t tried it 
recently.

Thanks,
Chris

It would be great if there were a stack property we could set that would 
specify what format outputted text would be. The default could be “native”; 
i.e., the native encoding for the platform, but then we could set it to things 
like “utf8” or “utf16” or “ISO”. It would essentially do the textEncode/decode 
for us.

Is this an idea that appeals to folks here?

Assuming you have UTF-8 encoded data from a source outside LiveCode:

local tUTF8Data — This is binary data
local tString   — This is a textual string
put textDecode(tUTF8Data, “UTF-8”) into tString

The important difference is that uniEncode becomes textDecode - because you are 
decoding some binary data to text. 

The big difference between 7.0 and previous versions is that Unicode text works 
everywhere - you don’t need to use special Unicode properties or commands any 
more.

If your external data is UTF-16 you still need to textDecode it - if you don’t, 
it will treat the data as 8-bit text and you’ll get corrupted text back. This 
8-bit default is necessary from a backwards compatibility point of view - if we 
changed it to accept UTF-16 by default, anyone who gets text from an external 
source and doesn’t textDecode it will suddenly find that their stacks don’t 
work.

One way of looking at things is that all external interfaces (files, processes, 
etc) return binary data and you need to do something to turn that into text 
(textDecode) and you need to turn your text into binary data when writing to 
them (textEncode). By using something like UTF-8 as an encoding, it also avoids 
the problems that occur because the “native” encoding differs between our 
platforms - it is MacRoman on OSX, CP1252 on Windows and ISO-8859-1 on Linux.
