That answer is probably bang on

Re: source of a socket error message

[Dar Scott via use-livecode]

This is very likely a loss of network availability and of that a loss of 
Internet availability.

The library will first look up the URI to get an IP address. The IP address is 
used to make a connection to the server.  The computer has (or can get) an IP 
address to use for making that look up.  Since that this the first operation, a 
loss of Internet will show up with that error.

If you are sure there is access to the Internet, then it might be that the DNS 
server is down. That seems unlikely, but possible. If the server IP is fixed, 
then use a cached version of the IP. Use hostNameToAddress() to get the IP 
address, save that on success, use the saved address on failure.

source of a socket error message

[Douglas Ruisaard via use-livecode]

Let me start this off by stating that the information I am seeking IS NOT due 
to an *issue* with LC.  Hopefully, I can make it clear why I am asking for 
assistance from this group in regard to the situation I am trying to deal with 
and why I need the LC expertise of this group as a resource.

In a portion of a large application, which has been distributed to a large 
number (5,000+) of remote/external sites, I have a call to a TCP socket:

on OpenCard 
...
 put ftp_server & ":" & tcp_port into temp1
 open socket to temp1 with message "NewConnection"
 wait for messages  
end OpenCard

Then there are a variety of "call-backs" based on when happens after I open the 
socket.  One of these call-backs is "socketError":

on socketError theID, theError
 close socket theID
 do_log " " & sftp_account && "file: " & "There is a problem with the TCP 
connection: " & theError, "connect", 3
...
end socketError

This works PERFECTLY 99.999% of the time.  However, occasionally I get a "mass" 
of errors (50 or 60) within a 1 hour period of time from a large variety of 
different external sites (I get all of the remote site's logs) ... i.e. many 
different sites connecting in from many different locations around the province 
of Ontario ... a very large place!

The error returned is: "can't resolve hostname"... returned in the "theError" 
parameter of the socketError function.

Here's where I need help.  I need to find out, with as great a level of detail 
as possible, EXACTLY what (from LC's "point-of-view") triggers this error, what 
part(s) of the LC engine are involved with generating this error and if there 
is more than the obvious cause of the remote site's DNS server (via their ISP 
or internal server(s)) not being able to "see" the hostname that could produce 
this error.

Although this "error" appears to be "common" from a variety of sources (none of 
which are written in LC, as far as I can tell)... I cannot find any "standard" 
by  which a DNS generates this specific message.  NSLOOKUP would be the closest 
candidate but even it doesn't produce this specific error of being "unable to 
resolve the hostname"... so that leaves LC with the responsibility of the 
content of the error.

I REALLY want to emphasize that, as far as I am concerned, this is not a 
problem with LC, in any manner... but I need to find out where and why LC 
generates this message.

I am not sure what or where to search for this error or what generates it from 
with the LC components but if someone could help me "find" a starting point, I 
should be able to reverse-engineer the logic.

The overall situation is fairly complex but I'd be very open to providing more 
details if anyone feels it is warranted.

Whatever help could be provided will be very, very appreciated!

Re: Best Temp Pass Autoresponder?

[Bob Sneidar via use-livecode]

Okay I thought I might be on to something. FYI for those who struggle with 
Gmail there are certain security settings that must be in place for free Gmail 
or hosted Google account to receive SMTP traffic: Two factor authentication 
must be off for the sending account, Access for less secure apps must be ON 
(this is optionally per account or domain wide for hosted accounts) and when 
sending from a public IP address for the first time, the device may need to be 
approved.

iOS cameraControl microphone permission bug

[Paul Kocsis via use-livecode]

Does anyone know if there is an iOS workaround for an app that uses a
cameraControl but does not need or use audio?  The bug is that iOS asks for
microphone permission even though I'm setting the audioDevice to empty.
Here is the bug report:

https://quality.livecode.com/show_bug.cgi?id=21438

I can't get an app accepted that uses cameraControl for stills because iOS
asks for microphone permission when its not actually needed.  Thanks to
anyone that can help!

RE: Best Temp Pass Autoresponder?

[Ralph DiMola via use-livecode]

I spoof email "from" address all the time(legitimately) using LC server
using on-rev account. When testing I found out a few things
1) you must put "mailFrom:" in the email internet header. Example "Mailfrom:
xx...@y.on-rev.com" This is not seen by email clients. They see the
"From" but "mailFrom" will be in the header.
  a) xx...@y.on-rev.com must be a valid email address
  b) y.on-rev.com must have valid ssl certificate.
2) setup SPF, DKIM, and DMARC DNS Records. This can be done via cPanel. SPF
is essential DKIM and DMARK increases your deliverability.
