The old implementation of sleep_forever() used a local Ipc_server
object, which is not announced (i.e., known) outside of the blocking
process/thread, to infinitely wait for incoming messages. In past and
present, this leads to problems (e.g., issues #538 and #1032).
Fixes#1135.
Fixes#538.
Fixes#1032.
The pointer-report facility used to report the screen-absolute position
of the mouse pointer. For nitpicker clients, however, this position is
meaningless because their coordinate is always constrained to the area
below the menu bar. This patch offsets the reported position
accordingly.
By separating the VFS from Noux, we become able to reuse the
VFS for libc-using programs. The most substantial change is the
removal of Noux::Sysio data structures from the VFS. Instead, the
Noux::Sysio refers to the VFS types now.
The new VFS library is located at 'os/include/vfs/'.
Furthermore, the patch removes various code duplications related
to pseudo file systems that provide a single file (block, zero,
random, terminal, null). The new 'Single_file_system' holds the
common boilerplate code for those.
Issue #999
Until now, there was not exception type for the condition where a
symlink was created on a file system w/o supporting symlinks, e.g., FAT.
The corresponding file-system server (ffat_fs) used to return a negative
handle as a work around. I added 'Permission_denied' to the list of
exceptions thrown by 'File_system::Session::symlink' to handle this case
in a clean way.
Genode's file system interface returns the number of directories
multiplied by sizeof(Directory_entry) as size of a directory. The
tar_fs server used to return zero. The fix counts the sub nodes of
the given directory.
If counter drops to 0, the wrap flag is set also. That means we have actually
no wrap around. The patch avoids to add too much time to the elapsed time
variable.
Issue #1106
The generalization of nitpicker's graphic backend changed the interface
of 'Mode::forget', which is a (non-pure) virtual function implemented
by 'User_state::forget'. Unfortunately, the signature change was not
applied to 'User_state::forget' so that the actual implementation was
no longer called. This inconsistency remained unnoticed because there
is a default implementation of the virtual function.
The effect of the omission of the 'User_state::forget' call was a
dangling pointer ('User_state::_pointed_view').
Lesson learned: Always annotate functions with the C++11 'override' when
implementing virtual functions.
The error message given to the 'errx()' function does not always contain a
'\n' character. Adding 'printf("\n")' ensures that the message appears on
the log console.
Fixes#1103.
Fix a use-after-free bug concerning the use case where the config
of the init process changes dynamically. The childs' services were not
removed from the corresponding Service_registry properly.
Fixes#1094
This patch removes the 'Framebuffer::Session::release()' function from
the interface to make the mode-change protocol consistent with the way
the Rom_session interface handles ROM-module changes. That is, the
client acknowledges the release of its current dataspace by requesting a
new dataspace via the 'Framebuffer::Session::dataspace()' function.
Fixes#1057
If opening a report session fails (for example because of invalid
session arguments) and an exception is thrown during the session
construction, the report would wrongly keep the enabled state.
By moving the assignment of the state after the construction,
the report stays disabled as it should be.
This patch improves the focus handling by updating the menubar each time
the user clicks on a different view, even the old and new view belong
to the same session.
For further information see: http://wiki.netbsd.org/rumpkernel/. In this version
I ported the central rump components to Genode in order to take advantage of
NetBSD file system implementation. The new 'dde_rump' repository contains the
Genode version of the rump libraries and a 'rump_fs' server that implements
Genode file-system-session interface. Currently ext2, iso9660, and fat
file-systems are supported.
