Originally, the convenience utility for accessing a process
configuration came in the form of a header file. But this causes
aliasing problems if multiple compilation units access the config while
the configuration gets dynamically updated. Moving the implementation of
the accessor to the singleton object into a library solves those
problems.
With this patch, the 'not implemented' messages of the pthread function
stubs always get printed to the Genode log console instead of stdout.
Issue #815.
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.
Hereby, the base libraries have been reduced to the following few
libraries:
- startup.mk contains the startup code for normal Genode processes.
On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
processes
Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.
Fixes#18
Most of the libs are needed for DNS related stuff. Since we now
have libc_resolv they are not longer needed. Infact they will
lead to undefined symbols so we remove them alltogther as build
dependency for the libc.
This patch implements the 'readv()' function in the libc.
A lock guard prevents the parallel execution of either or both of the
'readv()' and 'writev()' functions.
Fixes#279.
This patch implements the 'pread()' and 'pwrite()' functions in the libc.
A lock guard prevents the parallel execution of either or both functions.
Fixes#278.
This patch provides an implementation of the '_nanosleep()' libc function,
which blocks on a timed semaphore for the given time, but at least 10ms.
This should result in better performance than creating a timer connection
on every call (for thread-safety), but could still be improved.
Fixes#158.
Removed dummy implementation of '_ioctl'. This function is called
internally within the libc, i.e., by 'tcgetattr'. For running
libreadline in Noux, we need to hook into those ioctl operations via
the libc plugin interface.
