[Libreoffice-bugs] [Bug 111561] IOHIDDeviceClass::setElementDictIntValue() leaks memory
https://bugs.documentfoundation.org/show_bug.cgi?id=111561
--- Comment #14 from Alex Thurgood ---
That points to :
- (void) startListening: (id) sender {
(void)sender;
if ([self isListeningToRemote]) return;
at lines 147-149 in HIDRemoteControlDevice.m

See also lines 109-115 of RemoteControlContainer.m :
- (void) startListening: (id) sender {
#ifdef DEBUG
NSLog(@"Apple Remote: start listening to events... ");
#endif
for(NSUInteger i=0; i < [remoteControls count]; i++) {
[[remoteControls objectAtIndex: i] startListening: sender];
}
where the line :
[[remoteControls objectAtIndex: i] startListening: sender];
is identified as a leak point.

https://bugs.documentfoundation.org/show_bug.cgi?id=111561 --- Comment #7 from Alex Thurgood --- Perhaps this is linked to my input devices on this machine, I honestly don't know, as IOHIDDeviceClass is supposed to relate to USB and other connected hardware devices ? Whether this is due to a keyboard input (I use an Apple wireless keyboard on my test machine), or the USB mouse, or the display refresh ? No idea unfortunately. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=111561 --- Comment #6 from Julien Nabet --- I don't know what can be done here since it's Apple code. Moreover, I'm not sure there's a leak in this part of code. Perhaps it just shows that fonts are loaded in memory when scrolling and it's kept in cache. To test, you can scroll once the whole dropdown font list. Then you scroll again to see if consumed memory increases. BTW, would it be possible to have a bt of something similar to know where it's called in LO? -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

--- Comment #3 from Alex Thurgood ---
From
https://github.com/st3fan/osx-10.9/blob/master/IOHIDFamily-503.1.13/IOHIDLib/IOHIDDeviceClass.cpp
it appears to be this section of code:
void IOHIDDeviceClass::setElementDictIntValue(CFMutableDictionaryRef element,
CFStringRef key, uint32_t value)
{
CFNumberRef number = CFNumberCreate(kCFAllocatorDefault, kCFNumberIntType,
&value);
if ( !number )
return;
CFDictionarySetValue(element, key, number);
CFRelease(number);
}
