language.
CodeGenerator:
* modify to track stack depth
* add emit method that call's PythonVMCode's makeCodeObject
* thread filenames through in hackish way
* set flags for code objects for modules and functions
XXX the docs for the flags seem out of date and/or incomplete
PythonVMCode:
* add doc string describing the elements of a real code object
LineAddrTable:
* creates an lnotab (no quite correctly though)
handle most of the language syntax yet)
create NestedCodeGenerator used to generator the separate code object
that needs to be passed as an argument to MAKE_FUNCTION when a def
stmt is found (probably useful for class too)
change CodeGenerator.visitFunction to use the NestedCG
add CompiledModule class to handle creation of .pyc (pretty minimal
for now)
add makeCodeObject method to PythonVMCode that replaces symbolic names
with indexes into slots of the code code. the design of this
class will probably need to be revised.
*this* set of patches is Ka-Ping's final sweep:
The attached patches update the standard library so that all modules
have docstrings beginning with one-line summaries.
A new docstring was added to formatter. The docstring for os.py
was updated to mention nt, os2, ce in addition to posix, dos, mac.

Here is batch 2, as a big collection of CVS context diffs.
Along with moving comments into docstrings, i've added a
couple of missing docstrings and attempted to make sure more
module docstrings begin with a one-line summary.
I did not add docstrings to the methods in profile.py for
fear of upsetting any careful optimizations there, though
i did move class documentation into class docstrings.
The convention i'm using is to leave credits/version/copyright
type of stuff in # comments, and move the rest of the descriptive
stuff about module usage into module docstrings. Hope this is
okay.
compile.py: ASTVisitor framework plus bits of a code generator that
should be bug-for-buf compatible with compile.c

1. Comments at the beginning of the module, before
functions, and before classes have been turned
into docstrings.
2. Tabs are normalized to four spaces.
Also, removed the "remove" function from dircmp.py, which reimplements
list.remove() (it must have been very old).
Fixed a TypeError: not enough arguments; expected 4, got 3.
When authentication is needed, the default http_error_401 method calls
retry_http_basic_auth. The default version of that method expected a
data argument which wasn't provided, so now we provide the argument if
it was given and we also made the data argument optional.
Also changed other calls where data was optional to not pass data if
it was not passed to the calling method (in line with other similar
occurances).
'--help-commands' option).
Shuffled imports around in a few command modules to avoid expensive
up-front import of sysconfig (and resulting delays in generating list
of all commands).
* "--help" can now come either before or after particular commands
to get help on and can give help on multiple commands, eg.
"--help install dist" gives help on those two commands
* added "--help-commands" option, implemented by the 'print_commands()'
and 'print_command_list()' methods
Added 'link_static_lib()' method, and 'archiver' and 'archiver_options'
class attributes to support it.
Added 'link_executable()' method, and 'ld_exec' instance attribute
to support it.
'newer_group()' is now able to handle missing files, so we don't have
to kludge it by catching OSError when calling it.
'object_filenames()' and 'shared_object_filename()' now take 'keep_dir'
flag parameters.
'library_filename()' and 'shared_library_filename()' now respect
a directory component in the library name.
Various comment updates/deletions.
This patch changes the string-based exceptions to class-based
exceptions, so that you can fetch the unknown option as an
attribute. As far as I know, it is backward compatible.
[The new exception class is called GetoptError; the name error is an
alias for compatibility.]
I've changed the login command to force proper
quoting of the password argument. I've also added
some extra debugging code, which is removed when
__debug__ is false.
Added 'nuke_release_tree()' method to blow away the directory from
which the archive file(s) are created, and call it (conditionally)
from 'make_distribution()'.
Added 'keep_tree' option (false by default) to disable the call to
'nuke_release_tree()'.
install) the setup script itself.
Fixed 'build_module()' so we do *not* preserve file mode (which means
we can install read-only files, which makes the next installation
of this distribution fail -- at least under Unix); added a comment
explaining this.
consistency with 'build_ext' command option.
Changed 'compile()' and 'link_shared_object()' so 'include_dirs',
'libraries', and 'library_dirs' can be lists or tuples.
'generate_help()', 'wrap_text()' functions, and a little tiny test
of 'wrap_text()'.
Changed how caller states that one option is the boolean opposite of
another: added 'negative_opt' parameter to 'fancy_getopt()', and changed
to use it instead of parsing long option name.
want no output. Still no option for a happy medium though.
Added "--help" global option.
Changed 'parse_command_line()' to recognize help options (both for the
whole distribution and per-command), and to distinguish "regular run"
and "user asked for help" by returning false in the latter case.
Also in 'parse_command_line()', detect invalid command name on command
line by catching DistutilsModuleError.
a 'negative_opt' class attribute right after 'global_options'; changed
how we call 'fancy_getopt()' accordingly.
Initialize 'maintainer' and 'maintainer_email' attributes to Distribution
to avoid AttributeError when 'author' and 'author_email' not defined.
Initialize 'help' attribute in Command constructor (to avoid
AttributeError when user *doesn't* ask for help).
In 'setup()':
* show usage message before dying when we catch DistutilsArgError
* only run commands if 'parse_command_line()' returned true (that
way, we exit immediately when a help option is found)
* catch KeyboardInterrupt and IOError from running commands
Bulked up usage message to show --help options.
Comment, docstring, and error message tweaks.
Brian E Gallew, which were improved and adapted to OpenSSL 0.9.4 by
Laszlo Kovacs of HP. Both have kindly given permission to include
the patches in the Python distribution. Final formatting by GvR.
Bunch of little bug fixes that appeared in building non-packagized
distributions. Mainly:
- brain-slip typo in 'get_package_dir()'
- don't try to os.path.join() an empty path tuple -- it doesn't like it
- more type-safety in 'build_module()'
remove use of "os" module (bootstrap issues) and go to the underlying
platform-specific modules
fix problem in _compile() (trapped wrong error on permission issues)
add SysPathImporter and BuiltinImporter
put __file__ into modules imported from the filesystem. [backwards compat]
put __path__ into modules [backwards compat]
oops: it is doing this for all modules, not just packages.
comment and tweak to the PackageArchiveImporter
I regularly find that pdb sets the breakpoint on the wrong line when I
try to set a breakpoint on a function. This fixes the problem
somewhat.
The real problem is that pdb tries to parse the Python source code to
find the first executable line. A better way might be to inspect the
code object, or even have a variable in the code object
co_firstexecutablelineno, but that's too much work.
The patch fixes the problem when the first code line after the def
statement contains the start *and* end of a triple-quoted string. The
code assumed that the end of a triple-quoted string is not on the same
line as the start, and so it would skip to the end of the *next*
triple-quoted string.
have fork and execv (and friends) but not spawnv. They operate
exactly like the spawn functions on Windows. A limited set of needed
constants is also defined (P_WAIT, P_NOWAIT etc.).
Also add getenv() as a familiar alias for environ.get().
Now supports the full range of intended formats (tar, ztar, gztar, zip).
"-f" no longer a short option for "--formats" -- conflicts with new
global option "--force"!
At import time, getpass will be bound to the appropriate
platform-specific function. If the platform's echo-disabler is not
available, default_getpass, which prints the warning, will be used
I found the following patch helpful in tracking down a bug in some
code. I had appended time, the module, instead of time.time(). Not
sure if it is generally true that printing the repr of the object is
good, but I expect that most unpicklable things will have fairly
information and concise reprs (like files or sockets or modules).
Withdraw the change that Fred just checked in -- it was a poorly
documented feature, not a bug, to ignore I/O errors in read().
The new docstring explains the reason for the feature:
"""
this is designed so that you can specifiy a list of potential
configuration file locations (e.g. current directory, user's home
directory, systemwide directory), and all existing configuration files
in the list will be read.
"""
Also add a lower-level function, readfp(), which takes an open file
object (and optionally a filename).
XXX There are some other problems with this module, but I don't have
time to dig into these; in particular, there are complaints that the
%(name)s substitution from the [DEFAULTS] section doesn't work
correctly.
global options table.
Every Command instance now has its own copies of the global options,
which automatically fallback to the Distribution instance. Changes:
- initialize them in constructor
- added '__getattr__()' to handle the fallback logic
- changed every 'self.distribution.{verbose,dry_run}' in Command to
'self.{verbose,dry_run}'.
- filesystem utility methods ('copy_file()' et al) don't take 'update'
parameter anymore -- instead we pass 'not force' to the underlying
function as 'update'
Changed parsing of command line so that global options apply to all
commands as well -- that's how (eg.) Command.verbose will be initialized.
Simplified 'make_file()' to use 'newer_group()' (from util module).
Deleted some cruft.
Some docstring tweaks.
the code a bit and should make it work under Windows even with trailing
backslash.
Fixed a couple of docstrings.
Added comment about 'make_file()' possibly being redundant and unnecessary.
- change how we call it
- added methods 'library_dir_option()', 'library_option()', and
'find_library_file()' that it calls
Added 'force' flag; it's automatically "respected", because this class
always rebuilds everything! (Which it to say, "force=0" is not respected.)
Catch up with changes in 'gen_lib_options()':
- change how we call it
- added methods 'library_dir_option()', 'library_option()', and
'find_library_file()' that it calls
Added 'force' flag and changed compile/link methods to respect it.
has a directory component, then we only search for the library in
that one directory, ie. ignore the 'library_dirs' lists for that
one library.
Changed calling convention to 'gen_lib_options()' again: now, it takes
a CCompiler instance and calls methods on it instead of taking
format strings. Also implemented the new "library name" semantics
using the 'find_library_file()' method in the CCompiler instance.
Added 'force' flag to CCompiler; added to constructor and 'new_compiler()'.
Added 'warn()' method.
Catch up with renamed 'platdir' -> 'build_platlib' option in 'build'.
Don't call 'set_final_options()' in 'run()' anymore -- that's now
guaranteed to be taken care of for us by the Distribution instance.
If 'include_dirs' is a string, split it on os.pathsep (this is half-
hearted -- support for setting compile/link options on the command
line is totally lame and probably won't work at all).
Added 'get_source_files()' for use by 'dist' command.
Added code to 'build_extensions()' to figure out the "def file" to use
with MSVC++ and add it to the linker command line as an "extra_postarg".
Don't call 'set_final_options()' in 'run()' anymore -- that's now
guaranteed to be taken care of for us by the Distribution instance.
Rearranged to bit to allow outsiders (specifically, the 'dist' command)
to find out what modules we would build:
- 'find_modules()' renamed to 'find_package_modules()'
- most of 'build_modules()' abstracted out to 'find_modules()'
- added 'get_source_files()' (for the 'dist' command to use)
- drastically simplified 'build_modules()' -- now just a wrapper around
'find_modules()' and 'build_module()'
Tweaked some help strings to be consistent with documentation.
Don't call 'set_final_options()' in 'run()' anymore -- that's now
guaranteed to be taken care of for us by the Distribution instance.
- add 'extra_preargs' and 'extra_postargs' parameters (and use them!)
- got rid of 'build_info' kludge parameter
- added 'compiler_type' class attribute
- respect reordered arguments to 'gen_lib_options()'
Also added 'output_dir' parameter (catching up with older change in
CCompiler) -- BUT this is presently ignored by all methods!
Deleted some more docstrings redundant with CCompiler.
Dropped generated of "/DEF:" argument --- that's now done by
the 'build_ext' command.
- add 'extra_preargs' and 'extra_postargs' parameters (and use them!)
- added 'compiler_type' class attribute
- respect reordered arguments to 'gen_lib_options()'
which allowed us to get rid of the 'build_info' used in some places
(a temporary kludge to support MSVC++ "def" files).
Deleted big comment whining about that kludge.
Added 'compiler_type' class attribute.
Overhauled 'new_compiler()': now takes 'compiler' argument along with
'plat' (both optional with sensible defaults), and looks them both up
in the new 'default_compiler' and 'compiler_class' dictionaries to
figure out where to get the concrete compiler class from.
Reordered arguments to 'gen_lib_options()' to match the order in
which the arguments are generated (ie. -L before -l).
they make sure that 'set_final_options()' has been called, but isn't
called redundantly.
Changed Distribution to call 'ensure_ready()' where it used to call
'set_final_options()', and in a few extra places as well.
Lots of comment/docstring revisions and additions in both classes.
New one-liner utility methods in Command: 'find_peer()', 'spawn()'.
'alias_options' table and getting rid of some hairy code in the
Distribution constructor.
Resurrected the distribution options that describe the modules present
in the module distribution ('py_modules', 'ext_modules'), and added
a bunch more: 'packages', 'package_dir', 'ext_package', 'include_dirs',
'install_path'.
Updated some comments.
Added 'warn()' method to Command.
'Command.get_command_name()' now stores generated command name in
self.command_name.
Added global cache PATH_CREATED used by 'mkpath()' to ensure it doesn't
try to create the same path more than once in a session (and, more
importantly, to ensure that it doesn't print "creating X" more than
once for each X per session!).
distributions their own directory (and .pth file).
Overhauled how we determine installation directories in
'set_final_options()' to separate platform-dependence and take
'install_path' option into account.
Added 'create_path_file()' to create path config file when 'install_path'
given.
Only run 'install_py' and 'install_ext' when, respectively, there are
some pure Python modules and some extension modules in the distribution.
- rename 'dir' to 'build_dir'
- take 'package' from distribution option 'ext_package'
- take 'extensions' from distribution option 'ext_modules'
- take 'include_dirs' from distribution
Name keyword args explictly when calling CCompiler methods.
Overhauled how we generate extension filenames (in 'extension_filename()
and 'build_extension()') to take 'package' option into account.
