Merge lp:~epics-core/epics-base/add-rtems-4.12-api into lp:~epics-core/epics-base/3.16

[Andrew Johnson]

Heinz's RTEMS-4.12 port with the additional OS_API flag and reorganized to allow switching between kernel and posix implementations. For RTEMS the flag's value is set automatically based on a new RTEMS_SERIES setting in CONFIG_SITE.Common.RTEMS.

I can't implement Michael's request to use explicit paths to the source files without making significant changes to the build rules, and that would probably break a large number of external modules; the OS_API approach is backwards compatible.

I have checked that this branch builds against both RTEMS-4.9.2 and 4.10.2, but I don't have RTEMS-4.12 here to try it against. I have reservations about some of the posix implementations which I will bring up in review comments.

[Andrew Johnson (anj)]

This branch is *not* ready to merge, sorry, it needs some major cleaning up in places.

Please remove the extraneous comments from the README file.

There are some changes related to multicast options which will probably conflict with my osiSockTest branch (which is aimed at 3.15 but should be merged up first). The osiSockTest branch changes should take precedence over those from this branch.

Please remove the call to epicsThreadShowAll() from testHarness() in epicsUnitTest.c. There appear to be a few other extraneous changes (e.g. adding or removing blank lines to files which are otherwise unchanged) which I would like to see deleted. Code that should be indented but isn't, extraneous commented out lines etc. — these kinds of changes should never have been committed in the first place.

The various rtems-specific includes that have been added to a number of files (e.g. errlog.c) really should be put in an RTEMS-specific osd* header file, although I'm not sure which. We have tried to remove all OS-conditional includes from the general EPICS sources, and I don't want to let them back in again here.

I frown on the use of C++ // comments in .c files. Maybe they don't matter any more with the latest compilers, but I still have to support systems with compilers that don't allow them.

Does this branch include (some of) Michael's osiaddrinfo branch? There are changes in it which seem to be related to that and have his name on them, but I don't know the specifics. That branch had problems on MacOS and some other architectures, so this makes me a little nervous.

Dear Andrew,
thank you for your review.
For me it looks not like a diff to the merge request (and push) I made at ITER on 5th of october.

I pushed my code to git+ssh://<email address hidden>/~epics-core/epics-base/+git/add-rtems-4.12-api

git log shows :

Hello Heinz,

Ahhh, this merge request is for the old Bazaar branch, my sincere apologies for not noticing that. I will mark this one as old and propose a merge of your new version.

+<h3>Support for RTEMS 4.12</h3>
+
+<p>The next major release of the RTEMS real-time OS will be version 4.12 which
+contains many changes including the ability to support SMP systems. The earlier
+EPICS support for RTEMS made use of various RTEMS-specific kernel APIs which
+cannot be used on an SMP system, so the changes here required a completely new
+port to the Posix real-time APIs that RTEMS-4.12 now recommends. A new RTEMS
+configuration variable RTEMS_SERIES has been added which should be set to the
+first two components of the OS version number, e.g. 4.9. When this is 4.12 or
+greater the new libCom/osi/os/RTEMS-posix source files will be used; the older
+API source files can now be found in libCom/osi/os/RTEMS-kernel, and those which
+are common to both installations are in libCom/osi/os/RTEMS.</p>
+
+<p>Note that EPICS Base can only be built for a single RTEMS version at a time.
+  The RTEMS version number is set in the CONFIG_SITE.Common.RTEMS file and
+  cannot be different for specific targets. This allows different header files
+  to be used and installed for the two different APIs.</p>
+
+<h3>Support for multiple APIs in the same OS</h3>
+
+<p>The build configuration files for a particular build target may now select
+between multiple implementations with different OS APIs by setting the GNUmake
+variable <tt>OS_API</tt>. This changes the search path used for OS-specific
+source files, inserting a directory <tt>os/$(OS_CLASS)-$(OS_API)</tt> before
+the existing <tt>os/$(OS_CLASS)</tt> directory. Note though that the include
+file search path does not change, so OS-specific header files must be able to
+handle both APIs simultaneously, and their source files should go in the
+<tt>os/$(OS_CLASS)</tt> directory.</p>

 <h3>Echoless comments in iocsh</h3>
 
 <p>The way comments are parsed by the iocsh interpreter has changed. The
