Re: What are possible reasons for memory consumption going up on stack that isn't doing much?

2018-07-09 Thread Brian Milby via use-livecode
Pulling the fullclipboarddata could end up doing a bit of work depending on 
what is on it. You would probably be better off using the rawclipboarddata to 
avoid LC doing any processing just so you can detect changes.

Under normal circumstances, the various flavors of content will reflect the 
same thing. If concerned with style changes, then html may be the best one to 
check. If you are not, then a plain text variant would be simpler (I.e. 
shorter) to check.

update on this  the memory consumption is definately to do with one of
the messages that checks for changes in the clipboard every 333
milliseconds.. but does not retain what it finds.

there is nothing else going on the computer and as far as i know the
clipboard ISN't changingdoes the system make changes to the clipboard
even if ctrl c is not used? ..

.I use the "fullclipboard" data function to identify a change by comparing
it to the last known array from the fullcllipboarddata

is there a faster way of detecting a change in clipboard??, but have
full data when i do detect it?

the fullclipboard data has been  a little buggy.and i have some bug
reports to make. but its probably partly me doing it me doing it
wrong.

It may help to put a wait x milliseconds with messages in the repeat loop. This 
will give the engine a chance to do housecleaning.

Hi Douglas and Jaquie thank you for your input..I have double checked
my code and indeed my loop is safe from overlapping messagesI've been
working with schedulers for a while...  still not sure what could be
causing it..but it doesn't seem to get out of hand and clears itself out
periodically and returns to its base consumption (assuming no input).

thanks again

Like you, this is something I always do:

if "myMsg" is not in the pendingMessages then
  send "myMsg" to me in 250 milliseconds

Re: What are possible reasons for memory consumption ...

Or alternatively, check the pendingmessages and only send if there is not
already a message for the handler in question in queue.

I've had situations (in my case, bad coding) where I thought I was starting
a looping handler once ,but had left a call to that handler elsewhere
accidentally during the re-think process.  In those cases, even if it is a
seldom run handler that has the mistake, every time it is called, a new
instance of the loop starts.  In my case, (since I have trouble tracking
details as complexity grows beyond a certain point.. Small scale I'm great,
large scale, not so much) I've just made it a habit to always do the
pendingmessage check before sending again.  (I have lots of little rules
like this to help me manage my own personal limitations in a consistent
way.. Like always including a way to exit a tight repeat loop during
development at least, to avoid issues with runaways.)

Hmm. I tend to run on about things lately don't I?  Feel free to ignore any
extraneous blab.

To help determine if Brian's suggestion is occurring, you could put the 
following line in your "self perpetuating" code (assuming you're not running 
the code on a Mobile device which have no "messsage box") just before the 
"send... in x time ":

put the pendingmessages

If you see ANY output, then you've got multiple overlapping messages ... again, 
this assumes you only have ONE "loop" running.  Perhaps you can send the 
"offending" section of code for analysis?

Is it possible that multiple overlapping messages are being spawned?

You mention that the checks happen every 250ms... are you doing a send in time 
at the end of the check or at the start?

Thanks,

So i've been watching this running standalone a while  and it seems to
have stopped for now...I'm going to keep it running and see how high up it
gets.

Its like the engine is caching system events or something  I'll post
again in a few hours to see if its gotten any higher than this.

What are possible reasons for memory consumption going up on stack that isn't doing much?

2018-07-07 Thread Tom Glod via use-livecode
Hi folks,

I have a stack that has 2 or 3 self perpetuating messages which do a few
checks and the likethey run every 250 milliseconds or so.

There is no input data into the program unless I specifically send it there.

but while my program is sitting there repeating its loops and checks
for incoming input .. the memory consumption is steadily going up by .1
megabytes at a time.

I have watched my global variables , there is nothing being added to them
and most handlers have local variables that clear out when the handler
finishes.

This happens in IDE and standalone.

This app is made to stay in memory so this is not acceptable, because after
2 days it will get up to 2gb or whateverso i cannot let this remain.

maybe if i let it sit there it will eventually clear out ..but i haven't
seen that happen yet.

I just don't know where to look.  maybe i just found a memory leak
Thanks for any input
