Also + py-indent-line (TAB) should handle outdented lines better. + - New commands py-outdent-left (C-c C-l) and py-indent-right (C-c C-r) + +- The Library Reference has been restructured, and many new and +existing modules are now documented, in particular the debugger and +the profiler, as well as the persistency and the WWW/Internet support +modules. + +- All known bugs have been fixed. For example the pow(2,2,3L) bug on +Linux has been fixed. Also the re-entrancy problems with __del__ have +been fixed. + +- All known memory leaks have been fixed. + +- Phase 2 of the Great Renaming has been executed. The header files +now use the new names (PyObject instead of object, etc.). The linker +also sees the new names. Most source files still use the old names, +by virtue of the rename2.h header file. If you include Python.h, you +only see the new names. Dynamically linked modules have to be +recompiled. (Phase 3, fixing the rest of the sources, will be +executed gradually with the release later versions.) + +- The hooks for implementing "safe-python" (better called "restricted +execution") are in place. Specifically, the import statement is +implemented by calling the built-in function __import__, and the +built-in names used in a particular scope are taken from the +dictionary __builtins__ in that scope's global dictionary. See also +the new (unsupported, undocumented) module rexec.py. + +- The import statement now supports the syntax "import a.b.c" and +"from a.b.c import name". No officially supported implementation +exists, but one can be prototyped by replacing the built-in __import__ +function. A proposal by Ken Manheimer is provided as newimp.py. + +- All machinery used by the import statement (or the built-in +__import__ function) is now exposed through the new built-in module +"imp" (see the library reference manual). All dynamic loading +machinery is moved to the new file importdl.c. + +- Persistent storage is supported through the use of the modules +"pickle" and "shelve" (implemented in Python). There's also a "copy" +module implementing deepcopy and normal (shallow) copy operations. +See the library reference manual. + +- Documentation strings for many objects types are accessible through +the __doc__ attribute. Modules, classes and functions support special +syntax to initialize the __doc__ attribute: if the first statement +consists of just a string literal, that string literal becomes the +value of the __doc__ attribute. The default __doc__ attribute is +None. Documentation strings are also supported for built-in +functions, types and modules; however this feature hasn't been widely +used yet. See the 'new' module for an example. (Basically, the type +object's tp_doc field contains the doc string for the type, and the +4th member of the methodlist structure contains the doc string for the +method.) + +- The __coerce__ and __cmp__ methods for user-defined classes once +again work as expected. As an example, there's a new standard class +Complex in the library. + +- The functions posix.popen() and posix.fdopen() now have an optional +third argument to specify the buffer size, and default their second +(mode) argument to 'r' -- in analogy to the builtin open() function. +The same applies to posixfile.open() and the socket method makefile(). + +- The thread.exit_thread() function now raises SystemExit so that +'finally' clauses are honored and a memory leak is plugged. + +- Improved X11 and Motif support, by Sjoerd Mullender. This extension +is being maintained and distributed separately. + +- Improved support for the Apple Macintosh, in part by Jack Jansen, +e.g. interfaces to (a few) resource mananger functions, get/set file +type and creator, gestalt, sound manager, speech manager, MacTCP, comm +toolbox, and the think C console library. This is being maintained +and distributed separately. + +- Improved version for Windows NT, by Mark Hammond. This is being +maintained and distributed separately. + +- Used autoconf 2.0 to generate the configure script. Adapted +configure.in to use the new features in autoconf 2.0. + +- It now builds on the NeXT without intervention, even on the 3.3 +Sparc pre-release. + +- Characters passed to isspace() and friends are masked to nonnegative +values. + +- Correctly compute pow(-3.0, 3). + +- Fix portability problems with getopt (configure now checks for a +non-GNU getopt). + +- Don't add frozenmain.o to libPython.a. + +- Exceptions can now be classes. ALl built-in exceptions are still +string objects, but this will change in the future. + +- The socket module exports a long list of socket related symbols. +(More built-in modules will export their symbolic constants instead of +relying on a separately generated Python module.) + +- When a module object is deleted, it clears out its own dictionary. +This fixes a circularity in the references between functions and +their global dictionary. + +- Changed the error handling by [new]getargs() e.g. for "O&". + +- Dynamic loading of modules using shared libraries is supported for +several new platforms. + +- Support "O&", "[...]" and "{...}" in mkvalue(). + +- Extension to findmethod(): findmethodinchain() (where a chain is a +linked list of methodlist arrays). The calling interface for +findmethod() has changed: it now gets a pointer to the (static!) +methodlist structure rather than just to the function name -- this +saves copying flags etc. into the (short-lived) method object. + +- The callable() function is now public. + +- Object types can define a few new operations by setting function +pointers in the type object structure: tp_call defines how an object +is called, and tp_str defines how an object's str() is computed. + + +=================================== ==> Release 1.1.1 (10 Nov 1994) <== =================================== |
