Why since LV 8.1 the GPS acquisition is more longer ?

[Ludovic THEBAULT via use-livecode]

Hello,

Why since Livecode 8.1, GPS acquisition is more longer than Livecode < 8 on 
mobile ?

On the same place, my mobile  get coordinates within few seconds with the app 
compiled with LV < 8.1 but get coordinates after more than 15 seconds (more 
than one cycle on my script) if the app is compiled with LV > 8.1

Any ideas ?

Thanks

Here my script : 



on opencard :
if the environment is "mobile" and mobileCanTrackLocation() is "true » then

if "iphone" is in the platform then

get mobileLocationAuthorizationStatus()

if "denied" is in it or "restricted" is in it then ...

end if

mobileStartTrackingSensor "location"

wait 10 milliseconds with messages

put getcoord() into old « coordinates »

 mobileStopTrackingSensor « location »

end if

end opencard



on locationChanged pLatitude, pLongitude, pAltitude

set the coordonnees of this stack to pLatitude & tab & pLongitude & tab 
& pAltitude

end locationChanged




function getCoord
get the coordonnees of this stack

put mobileCurrentLocation() into tLocation

if tLocation is an array and tLocation["latitude"] <> "" and 
tLocation["longitude"] <> "" then

return tlocation

else

if the coordonnees of this stack <> it then 

return the coordonnees of this stack

else
put the seconds into timeout
repeat forever
if the seconds - timeout > 15 then 
answer « Is too long, Retry ? » with « Yes » or 
« No"
if it is « No » then
 mobileStopTrackingSensor « location"
exit repeat
else
 mobileStopTrackingSensor « location »
wait 200 milliseconds with messages
mobileStartTrackingSensor "location"
put the seconds into timeout ### new 
cycle
end if  
put mobileCurrentLocation() into tLocation
if tLocation is an array and 
tLocation["latitude"] <> "" and tLocation["longitude"] <> "" then  
exit repeat
else
put 
mobileSensorReading("location",true) into tlocation
if tLocation is an array and 
tLocation["latitude"] <> "" and tLocation["longitude"] <> " » then exit repeat

end if  
end repeat
if tLocation is an array and tLocation["latitude"] <> 
"" and tLocation["longitude"] <> " » then 
return location
else return the coordonnees of this stack ### old 
coordinates
end if
end if
end getCoord

It's ignoring the "breakpoint" text, too, not just the dots.

This is why I call them "Pirate Code Dots" (pad).

The IDE sees them as merely advisory . . .

And I'm again seeing the behavior that a red dot in a script that hasn't
yet hit a breakpoint is often ignored.

Or, with a break, a dialog, and another break, the break after the dialog
is ignored.

breakpoints being ignored

[Mike Kerner via use-livecode]

Explain this one:
8.1.3
create a stack
put a button on it
add some script
click in the margin to add a breakpoint - it shows grey with red border
run the script
breakpoint doesn't activate
Add a "breakpoint" line as the first line in the script
execute again
breakpoint still doesn't fire.

Have you considered running a standalone as your CGI?

Standalones can be run facelessly with a -ui flag, and while they 
require a one-time cost to set up a library to read stdin and parse the 
request and env vars, once you're set up you get something LiveCode 
Server can't offer:  complete compatibility with the LiveCode Script 
desktop syntax.


LC Server is great for many things, but since it doesn't work like LC on 
the desktop I don't use it for anything beyond testing.  I need to 
debug, and by not using the Server engine I can run my scripts right in 
the IDE.


Last week I was going to put together some notes on this to make using 
LC standalones as CGIs easier, but as luck would have it I couldn't get 
either Server or a standalone running as a CGI on either of my shared 
hosting accounts, for reasons that appear to be related to the RAM 
requirements from font loading:

http://quality.livecode.com/show_bug.cgi?id=14115

I have a workaround for that (thanks to some clever assist from Peter 
Brett and Mark Waddingham), but it's kinda funky and non-obvious to set 
up, so while it might work okay for me once in a while it's not the sort 
of thing I want to tell other people is reflective of how we do things 
in the LC world.  We are, after all, about simplicity, or at least 
strive for it.


But if you're on a VPS (about half our users are*) perhaps we can 
continue this discussion and explore simple means of using standalones 
as CGIs.  It really is a much simpler overall workflow once you get it 
going.



* I ran this survey on the LC forums - if you haven't voted please chime 
in on how you use LC on servers:

[Long] Moving a REST request from Desktop to Server

[Malte Brill via use-livecode]

Hi all,

I am trying to move a request I do from a desktop app to a liveCode server 
script and am facing the problem that some of the stuff I use (most of it 
libURL stuff) is not available on the server. Now I wonder how I could 
translate it…

Scenario is the following:
Problem is libURLLastRHHeaders() is unavailable on server and can not easiely 
be copied from libURL
Anyone got an idea?

local sCookieHeader

on mouseUp
local tURL,tUser,tPassWord,tCookie,tSubmitId,tsubmit,tJson,tJsonArray
local test
try
set the httpHeaders to empty
put „aUser" into tUser
put „aPassword" into tPassWord
put "264812" into tSubmitID
put "Log+in" into tSubmit
get libURLFormData("userName", tUser,"password", 
tPassword,"submit",tSubmit,"submitID",tSubmitId) — not available on Server, but 
can be copied from libURL
post it to url "http://test.com/login.php;
_storeCookies libURLLastRHHeaders() — needed to authenticate. 
libURLLastRHHeaders unavailable
set the httpHeaders to sCookieHeader
put fld "URL" into tURL
put URL tURL into tJson
catch theErr
put theErr
end try
end mouseUp


## Parse header returned from a server and create a cookie header that
## can be sent back: Cookie: cookie1;cookie2;cookie3;...
private command _StoreCookies pHeader
local theCharNo,theCookieLine,theLineNo,theOffset
put empty into sCookieHeader
put 0 into theOffset
repeat forever
put lineoffset("Set-Cookie:", pHeader, theOffset) into theLineNo
if theLineNo > 0 then
add theOffset to theLineNo
put line theLineNo of pHeader into theCookieLine
delete word 1 of theCookieLine ## Set-Cookie:
put offset(";", theCookieLine) into theCharNo
if theCharNo > 0 then
delete char theCharNo to -1 of theCookieLine
end if
put theCookieLine & ";" after sCookieHeader
put theLineNo into theOffset
else
exit repeat
end if
end repeat
if the last char of sCookieHeader is ";" then
delete the last char of sCookieHeader
end if
if sCookieHeader is not empty then
put "Cookie: " before sCookieHeader
end if
return empty
end _StoreCookies

With engine code, much of LC's community - including me - is in the same 
place as those using other scripting engines:  as scripters, relatively 
few among us have the C chops to contribute to that part of the project.


But with LiveCode we have options beyond the engine itself.  As you 
noted, it's more than just a scripting engine, it's a complete IDE, and 
with LiveCode everything in the IDE is written in LiveCode.


Those in a position to contribute fixes and enhancements can search the 
bug DB for items involving the IDE.


And to make that even easier Peter Brett provides a shortlist in each 
weekly community newsletter, grouped by difficulty - here's the most recent:

Hi Tiemo,

just made a little test on my "stock" Win10 installation (Parallels on my Mac).

WindowsMediaPlayer plays any MP4 fine, but nothing appears in the player of 
Livecode!?
So this is definitively a LC issue!

Then I downloaded and installed the latest LAVFilter codec package:

Et voila, I can play these MP4, which did not play before, in LC!?

Hi Jacque,

that's what I also already thought of. But I haven't found yet, how/where I 
could check for it. I have an old nice tool, called gspot, which usually tells 
me everything about any video, but it doesn't work with theses H.264 mp4's.  I 
was on the intel site and downloaded a media sdk, installed it on one of those 
not working machines, but without success. But actually I don't even know, if 
that codec is part of that media sdk, they don't describe the detailed content. 
So it was a shot into the dark and I didn't found yet a dedicated download for 
that codec.

Do the other machines have the mp4 codec installed? Most versions of Windows

Betreff: Trouble playing videos with MS DirectShow LC 8

Hello,



With LC 8.1.2 I changed the video standard in my programs from
Quicktime to the new standard interface DirectShow on Windows. I
recoded all videos to
mp4 with Intel QSV H.264.

On my developing W10 machine everything works fine in the IDE and
standalone. Now after release it looks like my developing machine is
"the only one" which can play the new videos in my new LiveCode program.

On a W7, W8 and other W10 machine I get the error "could not create
movie reference" when setting the filename of the player object.

Actually the DirectShow standard should be available from W7 to W10
and when just double clicking the video, it can be played on all
those other machines with the standard video player, so it doesn't
seem to be an codec issue. On the other hand something from the
environment must be different on my developing machine.

I also tried to build a new standalone with LC 9.0 dp3, but testing
the standalone it show the same issue.



Has anybody any idea, where to start searching?

What could be different on my developing machine as on all other machines?

Are there any known system requirements for using DirectShow? (which
I have set unconsciously on my machine)



Thanks for any ideas

Tiemo

Re: AW: AW: Trouble playing videos with MS DirectShow LC 8

[Phil Davis via use-livecode]

If you pick the video file with a file dialog and set the filename of 
the player to "it", will it play then? If so, maybe you're having a path 
issue.

Hi Jacque,

that's what I also already thought of. But I haven't found yet, how/where I 
could check for it. I have an old nice tool, called gspot, which usually tells 
me everything about any video, but it doesn't work with theses H.264 mp4's.  I 
was on the intel site and downloaded a media sdk, installed it on one of those 
not working machines, but without success. But actually I don't even know, if 
that codec is part of that media sdk, they don't describe the detailed content. 
So it was a shot into the dark and I didn't found yet a dedicated download for 
that codec.

Do the other machines have the mp4 codec installed? Most versions of Windows 
didn't ship with it, you had to install it separately.

Betreff: Trouble playing videos with MS DirectShow LC 8

Hello,



With LC 8.1.2 I changed the video standard in my programs from
Quicktime to the new standard interface DirectShow on Windows. I
recoded all videos to
mp4 with Intel QSV H.264.

On my developing W10 machine everything works fine in the IDE and
standalone. Now after release it looks like my developing machine is
"the only one" which can play the new videos in my new LiveCode program.

On a W7, W8 and other W10 machine I get the error "could not create
movie reference" when setting the filename of the player object.

Actually the DirectShow standard should be available from W7 to W10
and when just double clicking the video, it can be played on all those
other machines with the standard video player, so it doesn't seem to
be an codec issue. On the other hand something from the environment
must be different on my developing machine.

I also tried to build a new standalone with LC 9.0 dp3, but testing
the standalone it show the same issue.



Has anybody any idea, where to start searching?

What could be different on my developing machine as on all other machines?

Are there any known system requirements for using DirectShow? (which I
have set unconsciously on my machine)



Thanks for any ideas

Tiemo

Thanks Peter. I see some things in there that help me understand better what

AW: Trouble playing videos with MS DirectShow LC 8

[Tiemo Hollmann TB via use-livecode]

Hi Tim,

hmm, I didn't knew, that this codec is a hardware based codec. Do you think it 
definitely is tied to special intel hardware and won't run on every hardware 
and can't be added by a software codec? Btw. It runs also fine on my iMac.

That would be really bad for me, because it was the only codec my Sorenson 
squeeze offered me for H.264, where I can step frame by frame thru the video, 
what is a must for my app.

I’m certainly no expert on video encoding but since you used the Intel QSV

not support that hardware based encoder. You might have better luck and broader 
compatibilty using something like the default encoder in Handbrake.

Hello,



With LC 8.1.2 I changed the video standard in my programs from Quicktime to
the new standard interface DirectShow on Windows. I recoded all videos to
mp4 with Intel QSV H.264.

On my developing W10 machine everything works fine in the IDE and
standalone. Now after release it looks like my developing machine is "the
only one" which can play the new videos in my new LiveCode program.

On a W7, W8 and other W10 machine I get the error "could not create movie
reference" when setting the filename of the player object.

Actually the DirectShow standard should be available from W7 to W10 and when
just double clicking the video, it can be played on all those other machines
with the standard video player, so it doesn't seem to be an codec issue. On
the other hand something from the environment must be different on my
developing machine.

I also tried to build a new standalone with LC 9.0 dp3, but testing the
standalone it show the same issue.



Has anybody any idea, where to start searching?

What could be different on my developing machine as on all other machines?

Are there any known system requirements for using DirectShow? (which I have
set unconsciously on my machine)



Thanks for any ideas

Tiemo

Re: SHA1 cracked .... What are the chances this will be addressed in LC?

[Bob Sneidar via use-livecode]

NVM I think I see. I hash the user's password entry and compare the value to 
what is stored. But if the stored hash is an asymmetric one and cannot be 
decrypted, what is all the fuss about? Rainbow tables are all that is left, and 
you cannot create rainbow tables for every possible methodology. 

I'm wondering if this is much ado about nothing? No matter how a password is 
stored, it can always theoretically be compromised once someone gains access to 
the storage system. I get that having a different seed for each password makes 
it more difficult to be able to decrypt a captured hash in transit, but 
passwords MUST be stored somewhere, and if so, then encrypted, and if so, then 
never completely safely.

AW: Trouble playing videos with MS DirectShow LC 8

[Tiemo Hollmann TB via use-livecode]

Making some further tests, I discovered that there must be a relation to mp4
video files.
I tested the same standalone with an old avi file and that worked, but not
with some different mp4 files
But it can't be something in general, because the mp4 file can be played
fine with the same standalone on my W10 machine.
So I am still searching for an idea, what could be different on my machine
to "all" others.

Betreff: Trouble playing videos with MS DirectShow LC 8

Hello,

 

With LC 8.1.2 I changed the video standard in my programs from Quicktime to
the new standard interface DirectShow on Windows. I recoded all videos to
mp4 with Intel QSV H.264.

On my developing W10 machine everything works fine in the IDE and
standalone. Now after release it looks like my developing machine is "the
only one" which can play the new videos in my new LiveCode program.

On a W7, W8 and other W10 machine I get the error "could not create movie
reference" when setting the filename of the player object.

Actually the DirectShow standard should be available from W7 to W10 and when
just double clicking the video, it can be played on all those other machines
with the standard video player, so it doesn't seem to be an codec issue. On
the other hand something from the environment must be different on my
developing machine.

I also tried to build a new standalone with LC 9.0 dp3, but testing the
standalone it show the same issue.

 

Has anybody any idea, where to start searching?

What could be different on my developing machine as on all other machines?

Are there any known system requirements for using DirectShow? (which I have
set unconsciously on my machine)

 

Thanks for any ideas

Tiemo

Re: SHA1 cracked .... What are the chances this will be addressed in LC?

Thanks Peter. But then how will I know programmatically if the password is 
correct or not?

AW: Trouble playing videos with MS DirectShow LC 8

[Tiemo Hollmann TB via use-livecode]

Hi Tim,

choosing a video file via ask dialog and setting the filename of the player 
object to it sets an absolute path and that works on my machine fine.

Thank you for that hint

Tiemo

Make sure your file references to the movie are relative and not absolute. I’ve 
made that mistake once or twice.

Re: [ANN] Release 9.0.0 DP-5

[Richmond Mathewson via use-livecode]

One of the points that might be brought up at this point is that 
LiveCode in presented as a complete
programming language/packet in itself; there is no indication given that 
users of LiveCode are expected

to know other, lower-level languages too.

I suspect that a very high proportion of people who use LiveCode, 
whether one of the 2 commercial offerings, or the free offering, do so 
just because they have either (like myself) done their level best
to forget all the command-line languages of their youth, or don't know 
any and don't wish to learn any.

...or Community.

Finding the best mix of features for the the two proprietary licenses 
and the open source edition is a challenge.


I spent the last several days at the SoCal Linux Expo, and had good 
talks with team members from NginX, MariaDB, Nextcloud, and Ubuntu.


Those are among the strongest open source projects around, and all of 
them keep the projects going by offering paid services and software 
packages aimed at the enterprise audience.


On the surface it would appear that what they're doing is similar to 
what LiveCode is doing, and in some broad respects I suppose it is.


But I believe there are also at least two key differences:

- The for-fee-only offerings from those other companies are indeed
  specialized for larger customers, and the core free (libre and
   gratis) software is full-featured to the point of being best-of-
  breed.

- The communities surrounding those projects contribute a much larger
  percentage of the core free software.

With LiveCode, the company restricts a broader range of functionality 
to the proprietary editions, but they're also paying for a much larger 
percentage of programmer-hours going into the package.


Personally, I believe a healthy long-term balance would be more on par 
with those other projects, with more stuff shared across all editions 
and having that become possible because more of it comes from the 
community.


The tricky part is how to get from here to there.

Many of those projects are technologies that some of the world's 
biggest companies rely on, and many of those companies have full-time 
employees dedicated to contributing to those open source projects.  At 
Heroku, for example, they maintain two full-timers whose only job is 
to submit pull requests for postgreSQL, and Google pays for a lot of 
the development of Python.


The LiveCode world does not yet have a Google or Heroku in our 
community covering payroll for full-time engine developers.


So the question at hand for all of us, company and community alike, is:

   What is the best balance of free and non-free offerings
   that will not only grow the platform, but also keep the
   ship running in order to pursue that growth?

I don't have an easy answer on this.  But I believe it is a very 
important question.


And it may be harder to answer for this project than for others, for a 
great many reasons related to both the market the project serves and 
the complexity of delivering rich GUI authoring for so many platforms.


As just one comparison, my understanding is that the LiveCode code 
base is at least 30% larger than the code base for NginX.  Not only is 
LC a bigger project by that measure, but also arguably in terms of 
code complexity, because the touch-points for NGinX are limited to a 
relatively small number of OS APIs for networking and file I/O, but 
LiveCode needs those along with a vast number of broadly-varying GUI 
messaging APIs on top of that.


As I ponder this question, I recognize that while I'm not in a 
position to cover full-time salaries for LiveCode contributors, I can 
invest a certain percentage of my time each week to the project in 
light of the many practical benefits it offers my company.
