* Updated license headersJani Heikkinen2016-01-151-14/+20
| | | | | | | | | | | From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see Updated license headers to use new LGPL header instead of LGPL21 one (in those files which will be under LGPL v3) Change-Id: I046ec3e47b1876cd7b4b0353a576b352e3a946d9 Reviewed-by: Lars Knoll <>
* Add qt_safe_ftok wrapper for ftokLouai Al-Khanji2015-09-301-1/+1
| | | | | | | | | | | | | | | | The ftok function unfortunately can return duplicate keys even for different files if the same project id is used. This is discussed e.g. in Stevens' "Advanced Programming in the UNIX Environment". We want the key to be predictable so we cannot just pass a random number as the project id. To reduce the propability of key collisions we hash the file name with the project number as seed for a predictable value. This is the same approach taken e.g. by Apache, but the real fix is to move away from System V IPC completely once this is feasible on our supported platforms.

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <>
