When drivers signal that an action is completed, they might be still in the middle of a SSM and so its callback might not be called properly as part of the completion. This could make impossible to chain operations like open->enroll/list with some drivers (hey, synaptics, I'm looking at you!) when the next operation is called from the GAsyncReadyCallback of the previous call. To avoid this to happen, ensure that when a driver completes an operation, we handle the notification to the caller in a next idle iteration, not to end up in a possible broken state. Abstract this by using a function that handles the task return for each used task type to avoid duplicating similar functions doing all the same thing
libfprint ========= libfprint is part of the fprint project: https://fprint.freedesktop.org/ libfprint was originally developed as part of an academic project at the University of Manchester with the aim of hiding differences between different consumer fingerprint scanners and providing a single uniform API to application developers. The ultimate goal of the fprint project is to make fingerprint scanners widely and easily usable under common Linux environments. The academic university project runs off a codebase maintained separately from this one, although I try to keep them as similar as possible (I'm not hiding anything in the academic branch, it's just the open source release contains some commits excluded from the academic project). THE UNIVERSITY OF MANCHESTER DOES NOT ENDORSE THIS THIS SOFTWARE RELEASE AND IS IN NO WAY RESPONSIBLE FOR THE CODE CONTAINED WITHIN, OR ANY DAMAGES CAUSED BY USING OR DISTRIBUTING THE SOFTWARE. Development does not happen on university computers and the project is not hosted at the university either. For more information on libfprint, supported devices, API documentation, etc., see the homepage: https://fprint.freedesktop.org/ libfprint is licensed under the GNU LGPL version 2.1. See the COPYING file for the license text. Section 6 of the license states that for compiled works that use this library, such works must include libfprint copyright notices alongside the copyright notices for the other parts of the work. We have attempted to make this process slightly easier for you by grouping these all in one place: the AUTHORS file. libfprint includes code from NIST's NBIS software distribution: http://fingerprint.nist.gov/NBIS/index.html We include bozorth3 from the US export controlled distribution. We have determined that it is fine to ship bozorth3 in an open source project, see https://fprint.freedesktop.org/us-export-control.html ## Historical links Older versions of libfprint are available at: https://sourceforge.net/projects/fprint/files/ Historical mailing-list archives: http://www.reactivated.net/fprint_list_archives/ Historical website: http://web.archive.org/web/*/https://www.freedesktop.org/wiki/Software/fprint/
Description
Library for fingerprint readers
For unsupported devices, please see/edit https://gitlab.freedesktop.org/libfprint/wiki/-/wikis/Unsupported%20Devices
Do **not** open issues for unsupported devices that are already listed in the wiki page. For other devices, please simply add them to the wiki rather than opening a bug report here. Opening an issue to ask for a driver will not have any effect other than taking time from developers who need to close the issue again.
