A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.
Update #3254.

- Add 'rtems_shell_init_environment()' so a user can create the
shell environment without needing to run a shell.
- Move 'rtems_shell_lookup_topic', 'rtems_shell_can_see_cmd',
and 'rtems_shell_execute_cmd' from the internal interface to
the public interface.
Closes #3096.

Use this information to determine if a command is visible to the current
user and if the current user is allowed to execute this command.
|
|
Use the UID and GID of the executing user for the real and effective UID
and GID of the shell task in case no login check is present. This
prevents privilege escalation via shell scripts.
|
|
Remove rtems_current_shell_env as this is dangerous because
the env can be NULL if used outside of a valid shell with the
POSIX key to an env set up.
Clean up the usage of rtems_current_shell_env.
|
|
Provide rtems_global_shell_env as a public read-only variable for
backward compatibility.
|
|
Use posix keys for current shell environment instead of task variables. With
this patch the shell needs one posix-key and one posix-key-value-pair
configured.
Update documentation for the shell.
Adapt samples/fileio:
- Add necessary objects.
- Add login function and custom device name for better testing of the shell.

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

* shell/telnetd.c, shell/telnetd.h, shell/pty.c: New files.
* shell/shell.c, shell/cmds.c, shell/shell.h: Numerous improvments:
- The shell_init has a new parameter 'forever' because in
/dev/console you need that this process runs forever but in
tcp/ip not. (respawn?)
- A new task for every session opened trought tcp/ip telnet client.
(the chargen,daytime and more are possible of implementation but
I ask me if they are necesary)
- Exit from the session delete the task and when the client fails too.
- More cmds have been implemented. (very reduced version of these)
umask, chmod, id, whoami, rm, cat, ...
- A reduced line edit has been implemented.
Ctrl-C abort the input,
Ctrl-d in the first position gives EOF (logout).
'\b' and DEL makes the rubout operation.
I think that readline() for every session spents a lot of resources.

* Makefile.am, configure.in, wrapup/Makefile.am:
