Memory leakage problem

Recommended Posts

Hi!

I have a potential problem of memory leakage in the script I wrote and wonder if anyone will be able to suggest a potential source of the problem?

The script is desgined to log into secure website and constantly send HTTP GET request to obtain a list of tasks the client has assigned to us (the tasks are auctions, so swift actions are neccessary, hence the script) and then occasionally send HTTP POST to accept certain tasks based on certain criteria. It works 24/7 and works alright, but I noticed that amount of RAM it uses will increase significantly over time (say, it jumps from 20 000 K to 100 000 K in a few days).

I cannot post the entire script: it modestly big, also might contatin some sensetive information. But here's the main loop (like, exactly):

While True
    If Script_SignIn() And Script_GetTasks() Then Script_AcceptTasks()

    Sleep(10)
WEnd

The Script_ functions are here just to simplify the structure, they don't pass any parameters to each other, just return True \ False when finished and change some global variables when executed. Entire GUI is in OnEvent mode.

TMS_ functions are where the actual work is done, names are self-explanatory:

  • TMS_SignIn($sURL, $sUsername, $sPassword) -- returns $sAuthKeys (used subsequently in other functions to authenticate yourself, while session is active).
  • TMS_GetTasks(ByRef $oHTTP, $sURL, $sAuthKeys) -- this function is running constantly returning $avTasks (basically a table with all information I need to accept them), I'm passing a global variable $g_oHTTP to it, it creates HTTP object only once per session (hence ByRef, I don't want to locally create HTTP object at every pass, just create once and reuse) and in next loop I pass the object the function created to it again, $g_oHTTP is destroyed when session has ended and recreated in next loop after re-login.
  • TMS_AcceptTasks(ByRef $avTasks, $sURL, $sAuthKeys) -- returns True\False (changes $avTasks table slightly -- the status of acceptance if it's successful).
  • TMS_SignOut($sURL, $sAuthKeys) -- returns True\False.

These functions create local HTTP and HTML objects inside as well, I even "= 0" them at the end, even though I don't think I need to do this, since they are local variables. Still the problem persists.

Any ideas where to look?

The issue is on line 12 :)

Seriously, you cannot expect to post only 4 lines of code showing function calls, which by your own description are not interacting with one another, and expect people to diagnose and troubleshoot something as transient as a memory leak. Help us help you by providing more information.

@JLogan3o13, well, I was hoping there's some guide like memory leakage in AutoIt for dummies.

Ok, here's the script. I've removed some sensetive information. It's fully functional, though it won't leak memory until it's sending HTTP requests constantly, and for that I need to provide credentials, which of course I can't do.

The issue might be in some parts I've borrowed (check credits inside), say, I'm not quite understand ProgAndy's ASM gibberish in the TrayNotify.au3.

      This is yet another HTTP server written in AutoIt3.
      Originally based on jvanegmond's POST HTTP Server.
      It is designed to be used either as is, or by scripts for a HTTP communication between any browser and AutoIt3.
      It can run PHP and AutoIt3 CGI, if setup in the settings ini file.

      About AutoIt-API-WS
      AutoIt-API-WS is a light weight web server with expressive syntax, with the sole purpose of wrapping your existing AutoIt app with little to no effort.
      With AutoIt-API-WS you can send and receive data between any application or framework, as long they can handle HTTP requests, which is an industry standard today.
      Like my other communcations UDF AutoIt-Socket-IO AutoIt-API-WS is heavily inspired from the big boys, but this time its Laravel and Ruby on Rails.
      Features Highlights
      No external or internal dependencies required RESTful mindset when designed Expressive syntax Small codebase Heavy use of Michelsofts Dictionary object Limitations
      Not complient with any RFC, so something important could be missing. Time will tell! One persons slow loris attack will kill the process forever. Example of implemetnation (With screenshots)
      This is a basic cRud operation with the RESTful mindset in use.
      #include "API.au3" #include <Array.au3> _API_MGR_SetName("My APP DB adapter") _API_MGR_SetVer("1.0 BETA") _API_MGR_SetDescription("This adapter allows you to get this n that") _API_MGR_Init(3000) _API_MGR_ROUTER_GET('/users', CB_GetUsers, 'string sortBy', 'Get all users, sortBy can be either asc or desc. asc is default') _API_MGR_ROUTER_GET('/users/{id}', CB_GetUsersById, 'int id*', 'Get user by id') While _API_MGR_ROUTER_HANDLE() WEnd Func DB_GetUsers() Local $userA = ObjCreate("Scripting.Dictionary") Local $userB = ObjCreate("Scripting.Dictionary") $userA.add('id', 1) $userA.add('name', 'TarreTarreTarre') $userA.add('age', 27) $userB.add('id', 2) $userB.add('name', @UserName) $userB.add('age', 22) Local $aRet = [$userA, $userB] Return $aRet EndFunc Func CB_GetUsers(Const $oRequest) Local $aUsers = DB_GetUsers() If $oRequest.exists('sortBy') Then Switch $oRequest.item('sortBy') Case Default Case 'asc' Case 'desc' _ArrayReverse($aUsers) EndSwitch EndIf Return $aUsers EndFunc Func CB_GetUsersById(Const $oRequest) Local Const $aUsers = DB_GetUsers() Local $foundUser = Null For $i = 0 To UBound($aUsers) -1 Local $curUser = $aUsers[$i] If $curUser.item('id') == $oRequest.item('#id') Then $foundUser = $curUser ExitLoop EndIf Next If Not IsObj($foundUser) Then Return _API_RES_NotFound(StringFormat("Could not find user with ID %d", $oRequest.item('#id'))) EndIf return $foundUser EndFunc When you visit http://localhost:3000 you are greeted with this pleasent view that will show you all your registred routes and some extra info you have provided.

      When you visit http://localhost:3000/users the UDF will return the array of objects as Json
       
      And here is an example of http://localhost:3000/users/1

      goodmorning autoit team
      today am comming with some winhttp problems, i hope that you can help me to solve them.
      the first problem
      is when opening a request
      my forums api allow me to delete any post using the api key
      all functions work, i mean post / get
      but when i tried to use the delete verb it's gave me an html 404 error
      here is what am tried
      #include "WinHttp.au3" ; Open needed handles Global $hOpen = _WinHttpOpen() Global $hConnect = _WinHttpConnect($hOpen, "xxxxxxxx.com") ; Specify the reguest: Global $hRequest = _WinHttpOpenRequest($hConnect, "Delete", "/vb/Api/posts/10447/?hard_delete=true", default, default) _WinHttpAddRequestHeaders($hRequest, "XF-Api-Key:xxxxx") _WinHttpAddRequestHeaders($hRequest, "XF-Api-User:xxxxx") ; Send request _WinHttpSendRequest($hRequest) ; Wait for the response _WinHttpReceiveResponse($hRequest) Global $sHeader = 0, $sReturned = 0 ; If there is data available... If _WinHttpQueryDataAvailable($hRequest) Then $sHeader = _WinHttpQueryHeaders($hRequest, $WINHTTP_QUERY_CONTENT_DISPOSITION) ;Or maybe: ; $sHeader = _WinHttpQueryHeaders($hRequest, BitOR($WINHTTP_QUERY_RAW_HEADERS_CRLF, $WINHTTP_QUERY_CUSTOM), "Content-Disposition") Do $sReturned &= _WinHttpReadData($hRequest) Until @error msgBox(64, "", $sReturned) endIf ; Close handles _WinHttpCloseHandle($hRequest) _WinHttpCloseHandle($hConnect) _WinHttpCloseHandle($hOpen)  
      and here is the error message
      <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>403 Forbidden</title> </head><body> <h1>Forbidden</h1> <p>You don't have permission to access /vb/Api/posts/10447/ on this server.<br /> </p> </body></html>  
      i hope you can help me 
      thanks in advance

      I can TCP/IP in AutoIt, hence, make a HTTP deamon. Now, how can I HTTPS to use SSL !??
      Well, Apache has this "mod_proxy.so" module that can let me have SSL and what not is in Apache.
      All that is needed is to tell Apache what I wanna do by editing httpd.conf .
      # Implements a proxy/gateway for Apache. # 1. Open /Applications/XAMPP/etc/httpd.conf # 2. Enable the following Modules by removing the # at the front of the line. # - LoadModule rewrite_module modules/mod_rewrite.so # - LoadModule proxy_module modules/mod_proxy.so # - LoadModule proxy_http_module modules/mod_proxy_http.so # # 3. Copy and Paste below to the bottom of httpd.conf # <IfModule mod_proxy.c> ProxyRequests On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyVia Off ProxyPreserveHost Off ProxyPass /home/ http://127.0.0.1:84/home/ ProxyPassReverse /home/ http://127.0.0.1:84/home/ SetEnv proxy-nokeepalive 1 # ..since we are not using "keep-alive", we are using "close" </IfModule> ...et voila  
      I'm using XAMPP ( https://www.apachefriends.org/download.html )
      and this is my solution to avoid coding in PHP, as I feel more comfortable coding in AutoIt.
      A "muli-thread or concurrency" can be done by forking the socket ( https://www.autoitscript.com/forum/topic/199177-fork-udf-ish/ )
      but responses are under 20 ms., so I feel fine with a single thread.
      I modified an example ( attached below ), so can try out the concept.
      PS: I am not an Apache guru. I just discovered this and it opens a world of possibilities. In my case, I'm thinking of an API to query SQLite 
      PS2: I'm not gonna make Poll but do click like if you do
