* Change: In bootstrap, FindBootstrap.cmake, ccb (builder) & socInstaller,
suppress the "--qt5" argument as it the default now. Create a "--qt4"
to force building against the old one.
* Change: In bootstrap/cmake_modules/FindBootstrap.cmake, add a
"-Wl,--no-undefined" to the C++/ld flags to force checking of
undefined symbol at link time.
* In bootstrap/coriolisEnv.py, under WSL it seems that setting up the
LD_LIBRARY_PATH makes the linker to ignore /etc/ld.so.conf.
To avoid that, use ldconfig to import all the known paths into
LD_LIBRARY_PATH.
* Move all Python stuff under a common Python namespace "coriolis".
* Instead of having a series subtrees for each tool, integrate
everything in one common tree. So now, all components can be
located either with an absolute path from "coriolis" or, inside
cross-reference themselves through relatives imports.
* As a consequence, we only need to add ".../site-packages/coriolis/"
to the PYTHONPATH, and not a whole bunch of subdirectories.
And nothing, if installed in-system.
* The tree of free technologies configuration files is also moved
below "coriolis/technos" instead of "/etc".
* Supressed "cumulus" level for the plugins.
* All python modules are rewritten using relative imports except
for the configuration files that uses absolute import as they
can be cloned outside of the tree to serve as templates.
* Change: In boostrap/FindPythonSitePackages, include "/coriolis" in
Python_CORIOLISARCH and Python_CORIOLISLIB.
Provide a Python_SITELIB *without* "/coriolis" appended.
* Change: In cumulus/plugins/__init__.loadPlugins(), must prefix modules
read in the plugins directory by "coriolis.plugins.". No longer need
to add their path to sys.path.
* Change: In crlcore/python/technos/nodeX/*/devices.py, the scripts of
the layouts generators must be prefixed by "coriolis.oroshi.".
* Change: In CRL::System CTOR, no longer add the pathes of the various
plugins to sys.path. Only "site-packages/coriolis/".
* New: In Utilities::Path::toPyModePath(), new method to convert a
filesystem path into a python module path.
Examples:
"coriolis/plugins/block" --> "coriolis.plugins.block".
"coriolis/plugins/rsave.py" --> "coriolis.plugins.rsave".
* Change: In katanaEngine::_runKatanaEngine(), rename the hook script
initHook.py. No longer need to modify sys.path.
* Change: In BoraEngine::_runBoraEngine(), rename the hook script
initHook.py. No longer need to modify sys.path.
* Change: In UnicornGui::_runUnicornInit(), rename the hook script
initHook.py. No longer need to modify sys.path.
* Change: In cumulus.plugins.chip.constants, put the constants
outside __init__.py to avoid a loop at initialization.
* Bug: In all CMakeLists.txt, it seems I was doing a worng use of
target_link_library(). No longer add dependencies to the C++ base
library but instead either to the Python associated module or
to the final binaries. This was inderectly causing the linking
problem related to Python (which was a misdirection).
* Bug: Typo in FindLibexecinfo.cmake, do not use FindLib[E]xecinfo.
* Change: In CRL/ccore/CMakeLists.txt, activate SKIP_AUTOMOC on
bison/flex generated files.
* Bug: In viewer/PyHApplication, do not delete the C++ object in
the Python destroy method.
The CMake version set was so old that obsolete policies were being
enabled and breaking FindPython. 2.8 should still be old enough not to
cause problems for any current users.

* Change: In bootstrap/coriolisEnv.py, when all tries to locate the
installation root in predefined locations, try the directory the
script is installed in.
This allows for a user to use an installation made in another
user's account.
* Change: In bootstrap/coriolisEnv.py, the script was looking to
pythonX.Y (like "python2.7" or "python3.6") only. Now added
"major" only directories like "python2" or "python3".
* New: Python/C++ API level:
* Write a new C++/template wrapper to get rid of boost::python
* The int & long Python type are now merged. So a C/C++ level,
it became "PyLong_X" (remove "PyInt_X") and at Python code
level, it became "int" (remove "long").
* Change: VLSISAPD finally defunct.
* Configuration is now integrated as a Hurricane component,
makes use of the new C++/template wrapper.
* vlsisapd is now defunct. Keep it in the source for now as
some remaining non essential code may have to be ported in
the future.
* Note: Python code (copy of the migration howto):
* New print function syntax print().
* Changed "dict.has_key(k)" for "k" in dict.
* Changed "except Exception, e" for "except Exception as e".
* The division "/" is now the floating point division, even if
both operand are integers. So 3/2 now gives 1.5 and no longer 1.
The integer division is now "//" : 1 = 3//2. So have to carefully
review the code to update. Most of the time we want to use "//".
We must never change to float for long that, in fact, represents
DbU (exposed as Python int type).
* execfile() must be replaced by exec(open("file").read()).
* iter().__next__() becomes iter(x).__next__().
* __getslice__() has been removed, integrated to __getitem__().
* The formating used for str(type(o)) has changed, so In Stratus,
have to update them ("<class 'MyClass'>" instead of "MyClass").
* the "types" module no longer supply values for default types
like str (types.StringType) or list (types.StringType).
Must use "isinstance()" where they were occuring.
* Remove the 'L' to indicate "long integer" (like "12L"), now
all Python integer are long.
* Change in bootstrap:
* Ported Coriolis builder (ccb) to Python3.
* Ported Coriolis socInstaller.py to Python3.
* Note: In PyQt4+Python3, QVariant no longer exists. Use None or
directly convert using the python syntax: bool(x), int(x), ...
By default, it is a string (str).
* Note: PyQt4 bindings & Python3 under SL7.
* In order to compile user's must upgrade to my own rebuild of
PyQt 4 & 5 bindings 4.19.21-1.el7.soc.
* Bug: In cumulus/plugins.block.htree.HTree.splitNet(), set the root
buffer of the H-Tree to the original signal (mainly: top clock).
Strangely, it was only done when working in full chip mode.
* Change: In <tool>/CMakeLists.txt, add an USE_LIBBFD option to
enable the link against the BFD library. Latest versions seems
to have changed their API.
* Change: In bootstrap/ccp.by & builder/Builder.py, add an option
"--bfd" (and self._bfd) to enable BFD support.
Note: Keep the various hfnsX.py as toolboxes for future experiments.
* New: cumulus/plugins/block/hfns3.py, build the trunk of the
net as a RMST. First with the "Iterative One Steiner Point"
(terribly slow above 100 points) then with FLUTE.
For the global routing trunk, must be very cautious to
check that the cluster "graph point" is the one of the
it's buffer RoutingPad so both end up in the same GCell.
* New: cumulus/plugins/block/timing.py, stub for basic
timing computation and conversion between sink and
capacitance. Currently based on the fake 350nm given as
example in SxLib ("man sxlib"...).
* New: In flute, added a Python binding. Contains two methods: "readLUT()",
to load the POWV9.dat and POST9.dat and "flute()" to build a RSMT.
"flute()" takes a tuple of positions (themselves 2-uple) like:
( (x0,y0), (x1,y1,), ... (xN,yM) )
and returns a tuple of 3-uple of branches:
( (n0,x0,y0), (n1,x1,y1), ... )
In "flute.h", set the distance type (DTYPE) to int64_t to always
accomodate DbU::Unit.
As it now uses the Hurricane Python interface and the path utilities
from CRL Core, move it's compilation *after* them (see build.conf in
bootstrap).
