 Posted: Mon Nov 25, 2013 4:10 pm Post subject: Reading process total physical memory. |
 |
|
Hey DarkByte/mgr.inz.player.
Is there any feature to read process physical memory?
So sometimes users don't know what processes to pick, auto guess the process can work out well.
like let's say I have firefox, opera and chrome.
I have got all the processes list inside a table
| Code: | | processes = {... processes} |
So I'd love to do
| Code: | | for _,proc in pairs(processes) do print(PhysicalMemoryUsage()); end |
(useful if using high memory consuming games in your browser).
Or based the physical memory usage in the selected processes pick the 'best' process to attach.

Hmm, attach to process one by one.
Do "unknown initial value" 4-byte, writeable memory, newscan. Get number of results and quickly discard scan results. I say, it is possible.
I think I am able to create such Lua function - process suggester.

newscan takes a while, and people who uses dual core or even laptops (average), it'll take them several minutes to attach.
That's why I asked this.

@DaSpamer, I meant automated newscan, For example user press "suggest" button, and my Lua function will open each process from the list and do unknown scan.
Post your current work, I will add that "suggest" function (don't have time to create forms and etc.).
"it'll take them several minutes to attach."
It depends. We can try.
FlashPlayerPlugin which takes about 63MB have 974,848 results (unknown, 4-byte). It's pretty fast.

@darkbyte, i'l check it out.
@mgr.inz.player, take for example chrome and laptop with dual core 1.2ghz.
id say itll take several minutes to scan through 10 processes.
im using my phone at the moment.

As I said, we have to try.
You know, we can configure "unknown initial value" scanning as we want, for example we can use flag "+W-X-C" and "alignmenttype fsmLastDigits" set to "00". It should be much faster.
Note:
"fsmLastDigits" set to "0" should be about 4 times faster than default "fsmAligned 4"
"fsmLastDigits" set to "00" should be about 16 times faster than "last digits set to 0" (64 times faster than default)
Maybe I'm wrong?
Launching tasklist.exe from Lua script. You will use os.execute
This function will always create a command window, and it will always halt your current process until the window finishes

unknown initial value's first scan is not affected by fastscan
Also, io.popen works, which can open it without a command window and won't wait

"unknown initial value's first scan is not affected by fastscan"
Hmm, I thought it is, because:
For example, "first scan unknown":
fsmAligned 4 - I have "found: 735232"
fsmLastDigits 00 - I have "found: 11488"
(64 times less)
So, fastscan doesn't affect unknown, OK.
Maybe we can use this:
first scan, settings:
- value type: byte
- scan type: between
- HEX
- left value 00, right value FF
- +W-C-X
- fsmLastDigits 000 (three zeros)
Should be good right ?

Full working script (example, you can test it using various browsers).
Got little bit lazy in.
| Code: | local SmartAttach = {
wanted_processes = { 'chrome.exe'; 'plugin%-container.exe'; 'flashplayerplugin'; 'opera.exe'; 'iexplore.exe'; }; --> edit this.
currentprocesslist = { };

Try to make it fit with above function.
Also FlashPlayerPlugin takes 63 MB when it was started and the flash object has been closed (Like it's in Stand by mode..).
The moment you open a game, it jumps to 200MB to 1.5GB (depends on the game).

If using external tool like tasklist.exe is OK for you. You can change topic to [SOLVED].
Btw. Could you post "sort" function again (with indentation), I see something weird there "*0.0000001"

Heres the code.
| Code: | function SortByVarValue(t, var,method)
method = method or '+';
local _t = {};
local __t = {};
local ___t = {};
for k, v in ipairs(t) do
if _t[v[var]]==nil then
_t[v[var]] = k
else
for i=1,1000000 do
if _t[v[var]+i*0.0000001] == nil then -->quick fix because if _t[v[var]] exists the value would get overwritten.
_t[v[var]+i*0.0000001] = k
break
end
end
end
end
for k, v in pairs(_t) do
table.insert(__t, k);
end
if (method == '+' or method == nil) then
table.sort(__t, function(a,b) return a > b end);
elseif (method == '-') then
table.sort(__t, function(a,b) return a < b end);
end
for k, v in ipairs(__t) do
local varstart = v;
local recno = _t[varstart];
local entry = t[recno];
___t[k] = entry;
end
return ___t
end |
By using that script, I can do the following
Sort table based
| Quote: | | main_table->child_table->var. |
Example
| Code: |
t = {
{ name = 'Shon'; gender = 'Male'; age = 23 };
{ name = 'Amenda'; gender = 'Female'; age = 18 };
{ name = 'Nicole'; gender = 'Female'; age = 20 };
{ name = 'Charlie'; gender = 'Male'; age = 23 };
};
t = SortByVarValue(t , 'age', '-'); --> sort table from the smallest to the biggest.
for _,tab in pairs(t) do
print('name = ' .. tab.name .. '; gender = ' .. tab.gender .. '; age = '.. tab.age ..';');
end
--[[
name = Amenda; gender = Female; age = 18;
name = Nicole; gender = Female; age = 20;
name = Shon; gender = Male; age = 23;
name = Charlie; gender = Male; age = 23;
--]] |
Detailed explanation of my script,
| Code: | function SortByVarValue(t, var,method)
method = method or '+';
local _t = {};
local __t = {};
local ___t = {};
for k, v in ipairs(t) do
if _t[v[var]]==nil then --> checking if t[number] == equals to nil (example, t = table, v = child table, var = varible inside child tables (that holds a number), output example _t[18] (first table))
_t[v[var]] = k --> storing the inside _t[age] the table entry position from the main table.
else --> if the entry we want to use it taken already we must to store it somewhere that is not far (so it could be still sorted and be added right after the first value).
for i=1,1000000 do --> so I use here this small loop (incase there's more cases like this).
if _t[v[var]+i*0.0000001] == nil then --> we found empty entry to store the value (for example age is 5, and it position in the table is 5.0000001).
_t[v[var]+i*0.0000001] = k --> storing the inside _t[age] the table entry position from the main table.
break --> breaking out the loop.. duhh..
end
end
end
end
for k, v in pairs(_t) do
table.insert(__t, k); --> insert the entries to a new table.... (like the age position in the table before).
end
if (method == '+' or method == nil) then -->sorting the table the highest to the lowest or from the lowest to highest.. (based the 3rd parameter).
table.sort(__t, function(a,b) return a > b end);
elseif (method == '-') then
table.sort(__t, function(a,b) return a < b end);
end
for k, v in ipairs(__t) do
local varstart = v; --> age (as index inside the table).
local recno = _t[varstart]; --> since the __t index is sorted by age, so we're basically getting the entry[age] from _t table.. anyway, it returns the table t, child tables in order.
local entry = t[recno]; --> getting the actual table
___t[k] = entry; --> appending the table to the index k (1,2,3,4...n)..alt. I could do ___t[#___t+1].
end
return ___t
end |
Also, I won't change yet the title, maybe let's try to create the memory scan based method?
Edit:
Update, I had an mistake.
I forgot I send the object who called the attach method too, which messes up the part where I do
So change this function
| Code: | function SmartAttach:Attach(pid)
local index = self.combobox.ItemIndex
if index < 0 then
return
end
openProcess(self.currentprocesslist[pid or index+1].pid);
end |
to this
| Code: | function SmartAttach:Attach(PID)
local index = self.combobox.ItemIndex
if index < 0 then
return
end
openProcess(self.currentprocesslist[tonumber(PID) or index + 1].pid);
end |

I just asked because I'm using simpler sort function:
| Code: |
people = {
{ name = 'Shon'; gender = 'Male'; age = 23 };
{ name = 'Amenda'; gender = 'Female'; age = 18 };
{ name = 'Nicole'; gender = 'Female'; age = 20 };
{ name = 'Charlie'; gender = 'Male'; age = 23 };
}
function sortthis(T,K,reverse)
if reverse==true then
table.sort(T, function (a,b) return a[K] > b[K] end)
else
table.sort(T, function (a,b) return a[K] < b[K] end)
end
return T
end
people = sortthis(people,'age')
for _,v in pairs(people) do
print('name = ' .. v.name .. '; gender = ' .. v.gender .. '; age = '.. v.age ..';');
end
