That javascript code runs *in the user's browser", and so can easily 
keep track of idle time. or remaining time


Your LC code can only run on the server. And on the server, all you can 
do is - at the start of responding to a request - check how long it has 
been since the previous request from same user.


So that requires some storage between requests - whether in a database, 
or via cookie / session variable.

Quote for Signing & Notarizing a LC built application for Windows & Apple

[Tom Glod via use-livecode]

Hey,

Would love to know what it will cost me to sign an notarize my windows and
apple standalone.

I will provide application files and digital signature certificate from:

https://www.ksoftware.net/code-signing-certificates/

You do the rest, and return signed and submitted applications.
Please divide quote into Windows (codesign) and Apple (codesign & notarize)

My email is tom at makeshyft.com

Thanks,

RE: Downloading apk

[J. Landman Gay via use-livecode]

Thanks, that settles it. I'll just direct the user to the web site where 
they can click a link and it installs.


After I posted I did find the download in Chrome's download folder but I 
think that would generate too many support calls, especially since I 
couldn't find it immediately myself.

Re: SE crash possible vector

[Bob Sneidar via use-livecode]

The question then becomes, does the SE populate all the tabs even if they are 
not showing or are not currently selected? For example, when does the 
Documentation tab populate? If it does so whenever a dev clicks a command or 
keyword, regardless whether or not it is visible, then any bug present when 
visible will be present when not.

[Rick Harrison via use-livecode]

Hi Matthias,

I did the first cursory look at your lesson.

Nicely done!

It really is starting to make me dread
writing any future macOS apps though.
What a pain in the …!

I miss the good old days when I could
finish my program, zip it, and upload it.
Life was so easy by comparison then.
Oh well…

Thanks again for the lesson!

Re: SE crash possible vector

[J. Landman Gay via use-livecode]

I thought I'd narrowed it down to the tree view in the variable watcher 
pane. I've been leaving LC set to show the Documentation tab just in 
case, but that doesn't help because when you debug, LC switches to the 
Variables tab automatically.


So I tried pulling down the divider until the debugging panes didn't 
show at all. That makes debugging difficult but I can point to variables 
to see the values, though I can't examine arrays very well. I'm still 
crashing, I just haven't uploaded my current collection of logs yet. I'm 
not sure LC needs more than 30 logs anyway.

New lesson about codesigning an app, creating codesgined DMG and Notarize it for distribution outside of the Mac App Store

[Matthias Rebbe via use-livecode]

Hi,

some days ago i´ve published a lesson to Livecode´s Lesson area.
The lesson can be found here 
.

The lesson covers how to prepare an app/dmg for distribution outside the Mac 
Appstore for the upcoming Mac OS 10.15 Mojave.
- codesigning an app using shell
- creating DMG using hdiutil or the dropdmg command line tool
- codesigning dmg using shell
- notarizing and stapling the DMG using the shell
- there are also all needed prerequisites described including how to create 
certificates and app-specific passwords and so on.

I´ve also added a stack which does the basic steps like app codesgning 
(including some preparations before the signing) and creating and codesigning 
the DMG. So with the stack only notarizing and stapling has to be done manually.

I am currently working on a stack which will do also the complete 
notarizing/stapling process.

I tried to describe all the needed steps as detailed as possible. 

Maybe this lesson is useful for the one or other.

Regards,

Matthias

Re: source of a socket error message

[Douglas Ruisaard via use-livecode]

I *REALLY* appreciate the responses!  Beyond where (exactly) LC actually 
generates this message (I can see it in the LC executable in a large "look-up" 
table), I was hoping I could find it in a "read-able" script so I could trace 
the logic.

I'm trying NOT to exceed the scope of a subject related to this list-group and 
do not expect an actual solution to the issue.  By the way, there REALLY are 
5,000+ installations of the remote LC app spread all across the province of 
Ontario... which, if you're unfamiliar with Canada is worth look at on a map to 
see the geographic distribution "scope".  It's taken over 10 years to implement 
that number of sites for the very large medical information provider I contract 
to.

That's why Bob's "heebie jeebies" comment is SO relevant!  But, to wrap up the 
"story"... my ultimate goal, in regard to this request, is to avoid "allowing" 
my customer to dismiss the issues (which occur on a regular but erratic basis) 
as a remote ISP/DNS cause ... if at all possible.  I'd like them to exhaust any 
in-house possibilities or causes before they (and I) concede that the events 
are beyond their control or influence.  By eliminating any possibility that the 
connection issues are LC-related, I can honestly push the problem back into the 
customer's lap.

I will request that they now "map" even some of the affected sites with regard 
to the remote sites' ISP's.  One other relevant piece of information.. when 
this situation occurs... only a small percentage of the connecting sites are 
affected.  In the last incident (a few days ago)... over 1,000 site 
successfully connected in the same 1 hour time-window as the 50 site which 
exhibited the error!  "Normally" (however), any 1 hour period of time has fewer 
than 5 sites which may have encounter this "can't resolve hostname" error... 
THAT's acceptable... 50 in 1 hour is NOT.

Again.. thanks so much ... as always I can depend on this group for a very 
informed and helpful set of responses.

Cheers!

SE crash possible vector

[Bob Sneidar via use-livecode]

I may have a possible vector for the script editor crash bug. I was editing a 
script but had the Documentation tab open. I clicked somewhere at or towards 
the end of a line and it immediately crashed to the desktop. I'm wondering if 
the dictionary lookup is getting some bad data at the click?

Re: source of a socket error message

[Dar Scott via use-livecode]

It might be we are overcomplicating things. Maybe this just needs a support 
note to check the Internet connection.

I am having a little trouble picturing the situation here. And like you, I 
wonder about the description. Since one city was mentioned, I thought there was 
a possibility of a single ISP having trouble with DNS. I can't tell if this is 
WAN or Internet, controlled sites or customer devices, ...

Filtering...

Another thing I thought about is filtering. I have seen evil filtering based on 
the URL that returns an IP address that returns a page with ads based on the 
contents of the URL. That would not return an error, but could mess up code 
trying to parse the result. I suppose that a filtering name server might return 
a lookup error for either a URL or an IP. The latter is goofy, but if that 
happens, bad neighbors could cause a loss of name service for the app's server. 
Or if the URL is accidentally, temporarily or maliciously put on Santa's 
naughty list for an hour, DNS for it might be unavailable. Quad9 (9.9.9.9) will 
reply with a NXDOMAIN (non-existent domain) if a site is blocked. The solution 
might be a support note to avoid filtering if it is not otherwise needed.

(Long ago, before we had our own LiveCode function, I made a small DNS client 
library. About the same time I got a new DSL router. The library was 
inconsistent in getting a lookup error. I was frustrated trying to debug this, 
but I figured it out. At boot, the router kept changing the name service IP 
address to one that pointed a site that returned an IP that generated ads, even 
though I had saved a different IP. I don't remember how I fixed that.)

I already check if the user is logged in so that part isn’t an issue.

I was hoping there was some global server value I could check
or if there was an LC message like “on Idle” that would work.

Perhaps setting a session variable and the sessionLifetime
to a particular duration.  When the variable expires log the
show a sorry message due to timeout and have the
next button shown with the message log them out.

The following is a link to the javascript stuff I had referred
to before.  I just want a clean LC way to do the same thing.
