WebKit утечка памяти. Проблемы с кэшем., непонятно. Опции

[kwisp]

#include <QApplication>
#include <QWebView>

int main(int a,char** b)
{
    QApplication app(a,b);
    QWebView view;
    QAction reloadAct(&view);
    reloadAct.setShortcut(QKeySequence(QObject::tr("CTRL+R")));
    QObject::connect(&reloadAct,SIGNAL(triggered()),&view,SLOT(reload()));
    view.addAction(&reloadAct);
    view.load(QUrl("http://www.qtsoftware.com"));
    view.show();
    return app.exec();
}

в принципе и всё.
жмешь "CTRL+R" и наблюдаешь картину утечки памяти. так же память утекает даже не при полной перезагрузке страницы, а если к примеру бегать табами по ссылкам.
баг этот висит еще с 2008 года тролли не хотят его отрабатывать.
думал сначала что я такой кривой и чего то не досмотрел в описании, однако если взять браузер из %QTDIR%\domos\browser тоже память жрёт... с 42Мб с легкостью догна до 200Мб и походу предела нет.

Пробовал различные настройки QWebSettings тоже без результатов.
Память утекает даже если каждые десять минут удалять QWebView и создавать новый. Поэтому думаю что проблема с кэшем. У тролей нашел такой кусок кода:

QNetworkDiskCache *diskCache = new QNetworkDiskCache(this);
QString location = QDesktopServices::storageLocation(QDesktopServices::CacheLocation);
diskCache->setCacheDirectory(location);
networkAccessManager->setCache(diskCache);

пробовал устанавливать настроенный таким образом networkAccessManager в объект QWebPage -- без результатов.

Создал тролям таск с воплями о том что память утекает вроде пришло письмо. задаче назначен номер.
но всё же может есть у кого нитть идеи как работать с кэшем корректно??? может кто знает как пропатчить тролевский код???
я полез там конечно закручено прилично.

kwisp, в случае подобных ситуаций, баг или подозрение на него. Следует указывать версию и Qt и ОСьки

[kwisp]

в таск трекере всё указано.
первый таск Qt 4.4.0.
у меня 4.5.1 сейчас.
память утекает как под линуксом так и под виндой.

#include <QtWebKit/QWebView>
#include <QtGui/QAction>

[kwisp]

жесть короче.
какой же вывод можно сделать?
сколько времени придется потратить что поправить код троллей.?

[SABROG]

Не думаю, что утечку в 64Кб можно назвать утечкой. Скорее всего дело в кэше.

Кстати у кого-нибудь флэшки проигрываются?

[kwisp]

SABROG,
я тебя не пойму.
попробуй если интересно проследить за памятью при работе той же ароры-браузера или браузера из демок.

[SABROG]

Проследил за демкой browser, утечка ~115Кб

Я не говорю, что памяти не жрет, но утечки практически нет. Кстати release версия браузера жрет меньше памяти. И почему-то в браузере у меня работает YouTube, флешки, музыка. А в простейшем приложении с QWebView не работает.

[IMPOMEZIA]

баг этот висит еще с 2008 года тролли не хотят его отрабатывать.

Правильнее говорить об этом 248414, но описание не радует даже не смотря на приоритет.
Также был аналогичный баг у Arora 153 который был отправлен на bugs.webkit.org 24458 где был благополучно послан, т.е. "исправлен".

Проследил за демкой browser, утечка ~115Кб

+

однако если взять браузер из %QTDIR%\domos\browser тоже память жрёт... с 42Мб с легкостью догна до 200Мб и походу предела нет.

Утечка не утечка, но память он ест мегабайтами, притом Qt 4.5 в этом плане стал ещё хуже.

P.S. А вообще QtWebKit производит крайне удручающее впечатление, на поверхности всё вроде красиво и работает, т.е. на самом деле QtWebKit работает только формально, и похоже это всех устаивает.

SABROG,

Проследил за демкой browser, утечка ~115Кб

не знаю чем следил, однако.
запусти декмку браузера в виндамасдае и посомтри что происходит при каждой перезагрузки страницы не профайлером а обычным диспетчером. перезагрузи какуюнить страничку помассивнее раз 20-30.
запусти под линуксом что демку что арору и посомтри там сколько прога памяти жрет top`ом. после 20-30 перезагрузок одной и тойже страницы.

я написал приложение с WebKit память кончается после 3-4 часов интенсивной работы.

а вот chromium-browser не выжирает память, тото гугловцы его и допилили этот самый WebKit.
