From 1ed1ce9506e65f76fe5236194516f23d662bba0b Mon Sep 17 00:00:00 2001 From: Vaxry <43317083+vaxerski@users.noreply.github.com> Date: Sun, 5 May 2024 17:16:00 +0100 Subject: internal: new shared_ptr and weak_ptr implementation (#5883) moves std::shared_ptrs to a new implementation Advantages: - you can dereference a weak_ptr directly. This will obviously segfault on a nullptr deref if it's expired. - this is useful to avoid the .lock() hell where we are 100% sure the pointer _should_ be valid. (and if it isn't, it should throw.) - weak_ptrs are still valid while the SP is being destroyed. - reasoning: while an object (e.g. CWindow) is being destroyed, its `weak_ptr self` should be accessible (the sp is still alive, and so is CWindow), but it's not because by stl it's already expired (to prevent resurrection) - this impl solves it differently. w_p is expired, but can still be dereferenced and used. Creating `s_p`s is not possible anymore, though. - this is useful in destructors and callbacks. --- src/protocols/CursorShape.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/protocols/CursorShape.cpp') diff --git a/src/protocols/CursorShape.cpp b/src/protocols/CursorShape.cpp index 73c03ef3..2f25b22b 100644 --- a/src/protocols/CursorShape.cpp +++ b/src/protocols/CursorShape.cpp @@ -74,7 +74,7 @@ void CCursorShapeProtocol::onGetTabletToolV2(CWpCursorShapeManagerV1* pMgr, uint void CCursorShapeProtocol::createCursorShapeDevice(CWpCursorShapeManagerV1* pMgr, uint32_t id, wl_resource* resource) { const auto CLIENT = pMgr->client(); - const auto RESOURCE = m_vDevices.emplace_back(std::make_shared(CLIENT, pMgr->version(), id)); + const auto RESOURCE = m_vDevices.emplace_back(makeShared(CLIENT, pMgr->version(), id)); RESOURCE->setOnDestroy([this](CWpCursorShapeDeviceV1* p) { this->onDeviceResourceDestroy(p->resource()); }); RESOURCE->setDestroy([this](CWpCursorShapeDeviceV1* p) { this->onDeviceResourceDestroy(p->resource()); }); -- cgit v1.2.3
