 Posted: Sun Jul 17, 2016 2:25 am Post subject: Cheat Engine 6.5 & 6.5.1 BUG |
 |
|
Ok, So after my Rant about collectgarbage() here:
http://forum.cheatengine.org/viewtopic.php?t=575816
I Have tested some scenarios for "Access Violations".
First Test. 6.5
Huge Amount of LUA Defines . With a timer for collectgarbage()
Second Test. 6.5.1 No Lua. (Raw CE)
Both of these have produced an "Access Violation" after roughly 12 hours of running.
1. Address List is unable to edit Names. Under form launch style.
eg.. Double Click or LUA method of doDescriptionChange().
2. Auto Assemble Templates. All templates except "Cheat Table Framework code"
and "Call Ce Lua Function" give "Access Violation".
3. This one hit on 6.5 but not 6.5.1 "Add Address Manually" created an "Access Violation"
ALSO:
Things I have Experienced before is Unable to edit Value or Type in address list with Mouse Click. Loss of the Title Bar.
Also when CE's Lua doesnt do a normal release of memory and I execute a collectgarbage() several times I can force all these breaks almost instantly IF CE's memory is pushing over 500mb from LUA code not being removed.

I have experienced an Access Violation as well. I haven't been able to reproduce it though.
I wasn't using Lua, but I was using the Mono features.
After scanning for items and debugging code for awhile, I attempt to click the Add Address Manually button.
The Access Violation message pops up and then the standard CE window begins to show panes from the memory viewer window.
I am unable to do anything after that.
I had been able to click Add Address Manually without issue prior to this occurring.
However, after using CE scans, debug, and Mono features for awhile, it suddenly stops working.
I haven't been able to pinpoint exactly what series of actions cause this.

Some time ago I was testing progressbar lag (since Win7 progressbars have lag)
Below it is a code which is too fast for garbage collector.
Tested with print('Memory in use by Lua',math.floor(collectgarbage("count")/1024),'MB')
That way after a while this forces about 2GB:
| Code: | function showFormAndProgressbars()
if myyForm==nil then
myyForm=createForm(false)
myyForm.BorderStyle='bsSizeable'
myyForm.setSize(400,math.floor(50+#progressbardata*30))
for i=1,#progressbardata do
local pb=createProgressBar(myyForm)
pb.Name='myPb'..i
pb.Left=20; pb.Top=i*30-5
pb.setSize(360,25)
pb.Max=progressbardata[i].max
local lb=createLabel(pb)
lb.Name='myLbl'..i
lb.Align = alClient
lb.Alignment = 'taCenter'
lb.Layout = 'tlCenter'
lb.Caption = ''
end
end
if not myyForm.Visible then myyForm.show() end
for i=1,#progressbardata do
local pos=progressbardata[i].pos
myyForm['myPb'..i].Position=pos
myyForm['myPb'..i]['myLbl'..i].Caption = pos..'/'..(progressbardata[i].max)
end
end
function doDancingProgressbars()
progressbardata = {}
for i=1,23 do
progressbardata[i]={}
progressbardata[i].max = math.random(4,30)
progressbardata[i].pos = 0
end
if dancingProgressbarsTimer == nil then dancingProgressbarsTimer = createTimer(nil,true) end
dancingProgressbarsTimer.Interval = 100
dancingProgressbarsTimer.OnTimer = function (t)
for i=1,#progressbardata do
progressbardata[i].pos = (progressbardata[i].pos + 1 ) % (progressbardata[i].max+1)
end
showFormAndProgressbars()
end
end
doDancingProgressbars() |
Meanwhile I executed collectgarbage() few times. Memory in use by Lua every time was about 1 - 2MB.
No errors.

I was starting to think this was isolated to me only. So Last Night before bed. I ran 6 instances of CE.
4 instances on the Gaming Rig. 6.5 Raw, 6.5.1 Raw, 6.5 Heavy lua, 6.5.1 Heavy Lua
--- All produce "Access Violation" after waking up.
2 on Bedroom PC. Just 6.5 Raw.
---"Access Violation" after waking up.
It seems to be time sensitive.

Never got an Error by pushing a single LUA code to much. Mostly this would pop up when building forms or using timers to check Values. And Over a period Of TIME it would break...
Its still memory related, somewhere along the line CE loses track of where to go. I stated plenty of times I can force it with garbagecollect(). Im sorry that you can not reproduce it.
I dont wish to sound rude here but its happen to many times for it to be completely unrelated.
Your right Idk how to make it a produce an error with steps. But i do know that after a while of CE running and LUA taking up too much ram when collectgarbage() is ran excessively the Access Violation is almost instant.

official CE6.4 is compiled with "custom Lazarus 1.3"
official CE6.5 is compiled with "custom Lazarus 1.3"
official CE6.5.1 is compiled with official Lazarus 1.6
Could you do few more "raw tests" with those (it is only two exe, two dll and cmd):
- official CE6.4: link "official CE6.4 test.7z"
- and finally, this build (just now compiled from current source): link "CE6.5.1 from SVN test.7z"
extract package, rightclick on start.cmd, choose "run as admin". Wait.
When you get any error, bring "console window" (with gdb) to front, press CTRL+A, then ENTER, and paste into pastebin (or something).
Note: when "console window" is in "select text mode" it can freeze CE. To unfreeze, just bring "console window" to front and press space.

Additional note: I used the installer for 6.5, but I simply extracted 6.5.1.
Didn't clear registry or any of that other fun stuff. 
Wanted to check if akumakuja28 is working in a similar environment.

I used the installer on both. I have still experienced the issue after registry reset in 6.5.
@mgr
6.4 cmd window copy
https://www.dropbox.com/s/dsmf3haqzlxemwo/Cheat%20Engine%206.4.txt?dl=1
6.5.1 cmd window copy
https://www.dropbox.com/s/fge6g6h1fidxr7y/Cheat%20Engine%206.5.1%20github%2016.07.17%20mgr%20List.txt?dl=1
So I read this about 1pm and launched everything
- Setup a simple address list with groups
- everything worked fine.
- Added a cheat entry with "add address manually"
Upon rreturning from the gym @ 330ish
- Tried to edit the list and the CE builds both froze up.
- IDK what exactly im doing here but the console window did produce an error.
- Tried the space bar to unfreeze its still frozen Ill wait for instructions before I kill the process.
- I take it, it freezes on error.
Thank You.

see if you can get it to crash with only one display
(also, if you use any kind of desktop/screen enhancement tool, try disable it)

Yeah I can do that. Ill setup it up and get back to the thread with the results after work around 11pm Central time.
Wow I would have never expected this?
For for clarification. Should I run everything?
-- mgr's Builds
-- 6.5 (release)
-- 6.5.1 (release)

@DB, yes, I took his logs and analyzed, it crash here, for CE6.4 and CE6.5 and CE6.5.1:

begin
Info.cbSize := SizeOf(TMonitorInfo);
Result := GetMonitorInfo(Handle, @Info);
end; |

@akumakuja28
Looks like not related with Lua. More likely LCL do not handle some multi-monitor systems.
EDIT:
could be related:

Well thats awesome that the error is know now.
Checking in, No Address List errors on the mgr builds.
Would this cause the freakout in the auto assemble templates as well?
Also could the aggressive garbage collect hasten this errors? I still find it strange the behaviour of freeing memory and the error arising way too coincidental. Eitherway its reported and its not something LUA related.
Edit:
After reading mgr's edit link. I do frequently turn the tv back on and that causes windows to reactivate the displays as both setups I have are tv and monitor setups.
So this might not be LUA related at all which is great.
Thanks mgr darkbyte and zanzer

We still don't know. It might be that "multi-monitor problem" covered other problems.
Edit:
I applied this patch from svn.freepascal.org

Do the same "raw" test. (rightclick on start.cmd, choose "run as admin", wait, ....)

The new build with Monitor Patch seems to be running stable so far.
I have tried to force an error by reconfiguring displays and unplugging displays. No error yet on 2 hours of running.
Will update after a few more hours.
Thank you mgr for your speedy responses and fast action to resolve this bug.
