I am getting a reply right away. But this is interesting. I wonder if a similar 
call can be made to a SQL server? Just knowing I have an internet connection is 
not enough. I need to know if the SQL server is visible. I also need to know 
when the network has changed as I reauthenticate when the database connection 
disappears.

Re: Mobile Check Bandwidth Function

2017-07-04 Thread Sannyasin Brahmanathaswami via use-livecode
OK I'm back.. sheesh… Spectrum purchase Time Warner Cable for some Ka
bilion dollars and they run our show here now… but it took them four days to 
figure out that a splice in a wire between our main modem for the enterprise 
and the router on the street that was  probably filling up with water everytime 
it rains here (which is frequent this week.)

But it was a good time to be "up and down" on the internet as I had no choice 
but to focus on my connectivity scripts.  So this does go so far as giving us a 
bandwidth value, but I think I have a solution for the "reachability" thing..

Using LTE on my iPhone read all this business in Apple's Docs on "reachability" 
but even apple is using a ping to www.appleiphonecell.com  which returns the 
word "success". But our problem is

on pingServer
  put url https://www.himalayanacademy.com/ping.txt; into sOneLineStatus # the 
file contains one word "true"
end pingServer

Is blocking… on the desktop took sometimes 3 minutes (Yeah.. no kidding) for 
Livecode to step through that line and return "empty") 
on mobile the app will just hang… but the I had this "ahha!" moment where I 
thought "Duh, Scott Raney solved this 20 years ago" (really been that long?)

one never knows how much one has forgotten… years ago I did preload media and I 
thought 

"Wait! What about LOAD… URL Status…. these are none blocking"

So with the connection up and down I went about cooking up what I think is a 
low-level solution. 
disclaimer: I don't know what I'm doing and there is always a better way.

This is a text only library that is put into use on start up… after start up we 
send
 off

 connectivity_PingServer  in 500 milliseconds 

after the UI is finished loading


Local sPingURL,sServerAttempts # sURLStatusLog

on connectivity_PingServer
  # may have been cached before' but connectivity died so we need to do this 
first:
# just in case….
   unload URL "https://www.himalayanacademy.com/ping.txt; 
  put 0 into sServerAttempts
   # Logging: put empty into sURLStatusLog
   put "https://www.himalayanacademy.com/ping.txt; into sPingURL
   load url sPingURL
   dispatch "connectivity_UpdateStatus" to me
end connectivity_PingServer

on connectivity_UpdateStatus
   if URLStatus(sPingURL) = "cached" then
  put "true" into sOnLinestatus
  put 0 into sServerAttempts
# that's it nothing more to do…
   else
  put URLStatus(sPingURL)  into tURLStatus
  if (sServerAttempts > 10) and URLStatus(sPingURL)<> "cached" then
 put tURLStatus into sOnLinestatus
 dialog_CustomMsg true,"Offline or Low Bandwidth", 1500  
   
   # keep checking but don't hog the CPU... 
 put 0 into sServerAttempts # start over again
 send connectivity_PingServer to me in 10  seconds
  else
 # Logging
 --   put URLStatus(sPingURL) & cr after sURLStatusLog
 --   put sURLStatusLog
 add 1 to sServerAttempts
  dialog_CustomMsg true,"Connecting", 800 
 send connectivity_UpdateStatus to me in 800 milliseconds
  end if
   end if
end connectivity_UpdateStatus

# Use this in the module so we don't ping the server constantly.

function connectivity_GetStatus
   return sOnLineStatus
end connectivity_GetStatus

This is working on desktop and mobile

Any refinements you wizards can offer will be appreciated. 

I'm off to dig up an old library that Scott Raney had that I believe monitors 
download progress. and I bet playing around with this you could get a bandwidth 
value in a very "primitive" way by just downloading a small file and measure 
the time?

Actually we have access to basically anything you want on Android now via LCB 
and now that that’s the case if we provided an API for it we would do it via 
LCB too. I’m sure Ali could wrap it pretty quickly but it might be a good idea 
for the community to take it on and give us some feedback on our docs. The 
sooner people start wrapping and sharing code for system APIs the better.

If nothing else it's perhaps the most truly English-like token in the

natural languages. ;)


There are various interpretations of 'reachability' for iOS:

"Of course, Apple knows that many iPhone users want the option to 
perform many functions with one hand, so it created a nifty little 
feature called “Reachability.”"


https://bgr.com/2014/09/22/iphone-6-apple-features-iphone-6-plus/

According to the dictionary there are three LC functions here: 
reachabilityChanged, iphoneReachabilityTarget, and 
iphoneSetReachabilityTarget. I assume this "iphone" nomenclature is 
what's known as painting yourself into a corner.




And iOS only?  What do we do for the other 80% of the world?

Here is where a C applet would come in handy. Is it possible to have a C applet 
running that would be able to tell the LC engine that the network had changed? 
Otherwise, it would be REALLY USEFUL for a database application to "know" this.

Ping will not work. Some firewalls will prevent ICMP packets to and or from a 
source. If this library is to be used universally, you need a better method to 
determine if a device is responding on a known port. 

The tried and true method for doing this is telnet. Unfortunately, Microsoft 
decided NOT to enable the telnet client on Windows 8 and above. It has to be 
enabled by an end user. If you can create your own telnet stack, then it's 
doable. 

telnet  

check the result.

Hi.

Peter Bogdanoff via use-livecode wrote
> Can anyone share their "test bandwidth" library?

Found it difficult & time consuming to test the actual bandwidth, so I'm
testing the latency now. Bad latency usually relates to bad bandwidth ;-)

On my server I have a php script:
-

-

And in LC I use this function:
-
function INTest full
   put "http://myServer.net/tools/myip.php; into myIPURL
   if full then
  put the millisecs into t1
  put url myIPURL into myIP
  put the millisecs - t1 into t2
  return myIP & CR & t2
   else
  return url myIPURL
   end if
end INTest
-

Calling INTest() gives empty if we have no IN, else the actual public IP as
seen from the server (often useful anyways). Calling INTest(true)
additionally gives the latency on line 2.

Since this is small and not intrusive at all I can call it quite often to
monitor IN quality even on mobile.

Have fun!

2017-07-02 Thread Sannyasin Brahmanathaswami via use-livecode
Good thoughts,

Spotify actually will inform you that you don't have a connection even if you 
have 3G up..  

I would like to know how they do that.. because my app *can* ping our server 
over 3G… but Spotify deems the connection  insufficient to stream music and 
displays the "disconnected" icon.  So this goes to the speed testing you are 
looking for..

 I suspect another issue. I won't know for sure until I test tomorrow. But the 
mere act of "fishing on the internet" may hang the OS on mobile.

ergo.. on desktop this works

function pingServer
   # call from any where to inform user and disable activities
   # that require internet access to our server or any the external service
   put url "https://www.himalayanacademy.com/ping.txt; into sOnlineStatus 
   return sOnlineStatus
end pingServer

and if I unplug ethernet and turn off wifi  I can run from the msg box "put 
pingServer()" and not happens.. just returns empty

but my current behavior (still to be sorted) indicates that just try to fetch a 
URL, without a connection causes my app to hang.

I only discovered this serendipitously when the local router in our 
neighborhood suddenly started having trouble. We thought it was local to our 
LAN-place but the ISP in town said "People all over that area are complaining, 
their internet dropping on and off." of course has to happen on 4th July 
weekend (hehe)

My phone was connected to the local wifi→ to our modem → out the door down the 
street the "regional" router.  I was trying to show off my app and it would 
just hang on modules that expecting connectivity. but I *did* have my ping test 
functional. 

I have similar/parallel issues with in house apps that test to see if the LAN 
network is up or not. You can do peculiar things that cause Apple's network API 
to stop and think for 2 minutes!

Leads to 2 further questions

1) is there a low level check on iOS/Android for connectivity that we can use 
vs calling out to our server? Some people use Google DNS servers for this test, 
but it would be *any* http request.
  -- I looked  through all dictionary entries for "mobile*" and found nothing 
relevant, though possibly there is some sensor we can query?
2) anyone know how to turn off connectivity, on your phone, even if you have 
your sim card in? I'm not finding a way to actually turn off LTE or 3G access.
  -- I missing something simple there… on my Nexus 5  I don't have a SIM card 
(used only for testing, no cellular or data plan) but I can do everything if I 
am in proximity of our wifi, so for android I can just turn off wifi and the 
phone is "off line" for sure, but iOS?

I’m thinking that it might be possible to use a LC-only method:
1. A player control starts downloading a known-size media file.

2. The player reports when its  is no longer “loading,” then you 
calculate the data rate based on the elapsed time.
(In LC for Windows only, the player has a loadedTime property with which 
one could presumably calculate data rate.)

3. Possibly another method would be to set the callbacks of the player, 
such as one callback every 500 milliseconds. You would use a timer to figure 
how long it takes to receive each callback. If they are arriving every half 
second for a large file, then the speed needle would move the “Good” range. If 
the download is slow, the callbacks would be late, and the needle would move to 
the “you must be a rural Internet customer” area.

This kind of thing would require a “speed test” event before the results 
could be reported to the user.

Creating/testing this might be a challenge if you happen to have a good 
connection. You would have to somehow slow down your speed, or have someone 
else test it who does have a slow connection. Also, after loading a file, LC 
keeps it in a cache unless you dump it.

Mobile Check Bandwidth Function

2017-07-02 Thread Sannyasin Brahmanathaswami via use-livecode
Can  anyone share their "test bandwidth" library?

I'm looking for both

1) this phone is off line
--easy enough… ping your server, no response, = off line

2) check for bandwidth speed below some threshold and then inform  user
   -- be patient, your internet speed is slow, this may take time.

anyone already invent this wheel yet?
