fopen() in Genode?
by Sam Kerr 14 Feb '12

14 Feb '12

How can I use fopen() and write a file to disk? When I run the function below: void file_pass() { printf("File pass\n"); char buffer[] = {'s', 'a', 'm'}; FILE* f = fopen("temp","w"); fwrite(buffer, 1, 3, f); fclose(f); } I get the error: no plugin found for open("temp", int) Can anyone offer some advice? I am using L4Pistachio as my base.

I have a question about 'static inline void thread_switch_to(Native_thread_id tid)'. This function shall yield to a given thread, but what is the expected behavior if the targeted thread exists and is started but also paused? Greets, Martin

Framebuffer API change
by Norman Feske 25 Jan '12

25 Jan '12

Hello, as intermediate step to support the dynamic resizing of frame buffers, I have revisited the 'Framebuffer::Session' interface and thereby broke API compatibility. The following changes are worth noting: * The former 'Session::info' is no more. This function was a relict from the early days when we used to pass out parameters via pointers. * The new 'mode' function returns a structured object of the type 'Framebuffer::Mode' that contains the mode information and pixel- format definitions. * The new 'mode_sigh' function enables a client to register a signal handler at the framebuffer session. This signal handler gets notified in the event of server-side mode changes. * Via the new 'release' function, the client is able to acknowledge a mode change. By calling it, the client tells the server that it no longer uses the original framebuffer dataspace. So the server can replace it by a new one. After having called 'release', the client can obtain the dataspace for the new mode by calling 'dataspace()' again. For now, the primary motivation for this change is our desire to have resizable virtual framebuffers (i.e., adding a resizing capability to liquid fb). In the future, we envision the same mechanism to be used to dynamically change physical framebuffer modes as well.

Redundant github refs with rebase
by Martin Stein 25 Jan '12

25 Jan '12

Is there any idea to avoid redundant issue reference messages when using 'ref #X' in a commit message and the commit gets often rebased? To me it seems that rebasing is a very essential and often used. Greets, Martin

[RFC] I guess we need an IRC channel at Freenode
by Althaf 20 Jan '12

20 Jan '12

Considering the fact of faster and real time response with issues and support, i believe an IRC channel would be a of great help. Further, it doesn't hurt of register one so that the channel name it isn't stolen. I have seen this happen. -- /althaf k backer/

Hello, if I do make run/noux_vim it will _always_ rebuild vim, regardless of whether this is useful. Is there a way to avoid this? Julian

Git, website, how-to-contribute guide
by Norman Feske 17 Jan '12

17 Jan '12

Hello, to address the questions that are repeatedly popping up about the use Git for Genode's development, I have reworked the guide of how contribution to the project is supposed to work: http://genode.org/community/contributions The document is meant to provide all the points that are important for the development process. Currently, it contains notes about the common coding style, the use of the issue tracker, and the known best practice of writing commit messages. If you have further things to add, please let me know. The very last paragraph may be the most important one. Please note that the website content of genode.org does now correspond one-to-one to the textual content stored in the genode repository. For example, the "source code" of the contributions document is located at 'doc/contributions.txt'. This will make it straight-forward to contribute not only to the code base but also to the documentation. Because this new way of documentation management completely alleviates the need for a Wiki, the old Wiki is no more. Its content has been incorporated into the various documentation categories. The platform-specific documentation (in the repository located at the respective 'base-<platform>/doc' directories) can be found at the new "Base platforms" section: http://genode.org/documentation/platforms/index The challenges page ('doc/challenges.txt') has become part of the "About" section because it is closely related to the road map: http://genode.org/about/challenges Cheers Norman -- Dr.-Ing.
