I will try to describe my scenario as best as possible. I am a web developer mostly, so things like memory management I am not very familiar with. I am tasked with scraping data from a website (employer insisted with Windev). I have created two classes to handle the parsing of HTML and the DOM queries. With threads, I have managed to get the application to process a little over 20 pages per second. The problem is that the application continues to build used memory and even after it has completed, the memory is not freed. Here are the classes: stAttribute is Structure sName is string sValue is string END HTMLElement is a Class m_nId is int // internal unique numerical ID for this element m_sTag is string // the html tag m_sContent is string // the contents, formatted to have child elements replaced with <ID> m_arrParents is array of int // array of numeric IDs of heiarchial parent elements m_arrChildren is array of int // array of IDs of direct decendant elements m_arrAllChildren is array of int // array of ALL decendant elements m_arrAttributes is array of stAttribute dynamic // array of structure representing attributes m_pclDocument is HTMLDocument dynamic // reference to document class containing array of other elements END HTMLDocument is a Class m_sOriginal is string // raw html, for debugging m_arrElements is array of HTMLElement dynamic // flat array of classes representing all of the elements m_nElementInt is int = 1 // iternal incremental numeric ID to represent each element m_arrSelfClose is array of string // array of html tags that are self-closing END I have taken care to ensure that every class declaration is dynamic. I only declare variables at the beginning of the functions, as to avoid the issue with loops. I am manually deleting the HTMLDocument class at the end of my function, I would assume that would also delete all the HTMLElements contained within it. I had tried also deleting them in the destructor function, but it did not seem to make a difference. Now, the Document class contains an array of Elements, and the element class contains a reference back to the Document. Could that be a potential issue?30WEBDEVen_UShttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/65454-trying-solve-memory-leak-issue/read.awpmoderateur@pcsoft.fr (El moderador)webmaster@pcsoft.fr (El webmaster)Darryl MEGANOSKIpcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/65454-trying-solve-memory-leak-issue-65519/read.awp18 May 2018 20:33:04 ZFor anyone interested now or in the future, it seems to be more related to the execution of threads rather than the classes. …https://forum.pcsoft.fr/es-ES/pcsoft.us.windev/65454-trying-solve-memory-leak-issue-65519/read.awphttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/65454-trying-solve-memory-leak-issue-65519/read.awpTrying to solve a memory leak issueDarryl MEGANOSKIpcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/65454-trying-solve-memory-leak-issue-65464/read.awp15 May 2018 19:53:34 ZOkay, So I'm getting the weirdest behavior from tests now, and I hope someone can shed some light on why this would be the case.…https://forum.pcsoft.fr/es-ES/pcsoft.us.windev/65454-trying-solve-memory-leak-issue-65464/read.awphttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/65454-trying-solve-memory-leak-issue-65464/read.awpTrying to solve a memory leak issueDarryl MEGANOSKIpcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/65454-trying-solve-memory-leak-issue-65461/read.awp15 May 2018 16:23:40 ZYes, I meant the variables that hold the classes are typed as dynamic when I create instances of them.
