Release notes for the Debian packages: + 2. Notes for developers using the Debian Python packages: + +Release notes and documentation from the upstream package are installed +in /usr/share/doc/python/. + +Up-to-date information regarding Python on Debian systems is also +available as http://www.debian.org/~flight/python/. + +There's a mailing list for discussion of issues related to Python on Debian +systems: debian-python@lists.debian.org. The list is not intended for +general Python problems, but as a forum for maintainers of Python-related +packages and interested third parties. + + + +1. Release notes for the Debian packages: + + +Results of the regression test: +------------------------------ + +The package does successfully run the regression tests for all included +modules. Seven packages are skipped since they are platform-dependent and +can't be used with Linux. + + +Noteworthy changes since the 1.4 packages: +----------------------------------------- + +- Threading support enabled. +- Tkinter for Tcl/Tk 8.x. +- New package python-zlib. +- The dbmmodule was dropped. Use bsddb instead. gdbmmodule is provided + for compatibility's sake. +- python-elisp adheres to the new emacs add-on policy; it now depends + on emacsen. python-elisp probably won't work correctly with emacs19. + Refer to /usr/doc/python-elisp/ for more information. +- Remember that 1.5 has dropped the `ni' interface in favor of a generic + `packages' concept. +- Python 1.5 regression test as additional package python-regrtest. You + don't need to install this package unless you don't trust the + maintainer ;-). +- once again, modified upstream's compileall.py and py_compile.py. + Now they support compilation of optimized byte-code (.pyo) for use + with "python -O", removal of .pyc and .pyo files where the .py source + files are missing (-d) and finally the fake of a installation directory + when .py files have to be compiled out of place for later installation + in a different directory (-i destdir, used in ./debian/rules). +- The Debian packages for python 1.4 do call + /usr/lib/python1.4/compileall.py in their postrm script. Therefore + I had to provide a link from /usr/lib/python1.5/compileall.py, otherwise + the old packages won't be removed completely. THIS IS A SILLY HACK! + + + +2. Notes for developers using the Debian python packages: + + +Embedding python: +---------------- + +The files for embedding python resp. extending the python interpreter +are included in the python-dev package. With the configuration in the +Debian GNU/Linux packages of python 1.5, you will want to use something +like + + -I/usr/include/python1.5 (e.g. for config.h) + -L/usr/lib/python1.5/config -lpython1.5 (... -lpthread) + (also for Makefile.pre.in, Setup etc.) + +Makefile.pre.in automatically gets that right. Note that unlike 1.4, +python 1.5 has only one library, libpython1.5.a. + +Currently, there's no shared version of libpython. Future version of +the Debian python packages will support this. + + +Python extension packages: +------------------------- + +According to www.python.org/doc/essays/packages.html, extension packages +should only install into /usr/lib/python1.5/site-packages/ (resp. +/usr/lib/site-python/ for packages that are definitely version independent). +No extension package should install files directly into /usr/lib/python1.5/. + +But according to the FSSTND, only Debian packages are allowed to use +/usr/lib/python1.5/. Therefore Debian Python additionally by default +searches a second hierarchy in /usr/local/lib/. These directories take +precedence over their equivalents in /usr/lib/. + +a) Locally installed Python add-ons + + /usr/local/lib/python1.5/site-packages/ + /usr/local/lib/site-python/ (version-independent modules) + +b) Python add-ons packaged for Debian + + /usr/lib/python1.5/site-packages/ + /usr/lib/site-python/ (version-independent modules) + +Note that no package must install files directly into /usr/lib/python1.5/ +or /usr/local/lib/python1.5/. Only the site-packages directory is allowed +for third-party extensions. + +Use of the new `package' scheme is strongly encouraged. The `ni' interface +is obsolete in python 1.5. + +Header files for extensions go into /usr/include/python1.5/. + + +Installing extensions for local use only: +---------------------------------------- + +Most extensions use Python's Makefile.pre.in. Note that Makefile.pre.in +by default will install files into /usr/lib/, not into /usr/local/lib/, +which is not allowed for local extensions. You'll have to change the +Makefile accordingly. Most times, "make prefix=/usr/local install" will +work. + + +Packaging python extensions for Debian: +-------------------------------------- + +Maintainers of Python extension packages should read README.maintainers. + + + + + 03/09/98 + Gregor Hoffleit <flight@debian.org> + +Last change: 07/16/1999 |
