Open Source Ideas<\/h1>\n

The development of deepin now is fully based on the works of the upstream communities. Despite our original open source projects with more than 1 million lines codes, we know very well about the open source ideas that \"What comes from the open source should be used for open source\", so that we could give all these codes and features back to the upstream communities and better promote the open source all over the world.<\/p>\n

Contributions to Upstream<\/h1>\n

Here are the contributed code patch and brief introductions to the upstream \u00a0communities:<\/p>\n

Wine<\/h2>\n

Deepin Wine Team will develop many functions that can complete Wine's API every day to make Windows Applications run better on Linux. Like QQ, Xunlei and RTX, these applications used Deepin contributed patches, and here are the patch list:<\/p>\n

Metacity&Mutter<\/h1>\n

Deepin Window Manager is an advanced window manager that developed based on metacity and mutter. deepin-metacity based on metacity and deepin-wm is based on mutter. During the development process, we've found a lot of bugs and features that need to improve, here are the details:<\/p>\n

PyGTK<\/h1>\n

When using Python + Gtk+ to develop graphical applications, Deepin Team has found that pangocairo will not destruct the layout object while rendering fonts. This could cause a very serious memory leak issue, and Deepin Team has send a patch to pygtk developer to solve the problem. Here is the patch:<\/p>\n
