This uses the same precautions when trying to find a temporary
directory as when the actual tempfile is created (using O_CREAT and
O_EXCL). On non-posix platforms, nothing is changed.
"""
In the course of debugging this I also saw that cPickle is
inconsistent with pickle - if you attempt a pickle.load or pickle.dump
on a closed file, you get a ValueError, whereas the corresponding
cPickle operations give an IOError. Since cPickle is advertised as
being compatible with pickle, I changed these exceptions to match.
"""
to add the "display metadata" options: --name, --version, --author,
and so forth. Main changes:
* added 'display_options' class attribute to list all the "display only"
options (--help-commands plus the metadata options)
* added DistributionMetadata class as a place to put the actual
metadata information from the setup script (not to be confused with
the metadata display options); the logic dealing with metadata
(eg. return self.name or "UNKNOWN") is now in this class
* changed 'parse_command_line()' to use the new OO interface provided
by fancy_getopt, mainly so we can get at the original order of
options on the command line, so we can print multiple lines of
distribution meta-data in the order specified by the user
* added 'handle_display_options()' to handle display-only options
Also fixed some crufty old comments/docstrings.
class. (Mainly this was to support the ability to go back after the
getopt operation is done and get extra information about the parse,
in particular the original order of options seen on the command line.
But it's a big improvement and should make it a lot easier to add
functionality in the future.)
- DistutilsOptionError is now documented as it's actually used, ie.
to indicate bogus option values (usually user options, eg. from
the command-line)
- added DistutilsSetupError to indicate errors that definitely arise
in the setup script
- got rid of DistutilsValueError, and changed all usage of it to
either DistutilsSetupError or ValueError as appropriate
- simplified a bunch of option get/set methods in Command and
Distribution classes -- just pass on AttributeError most of
the time, rather than turning it into something else
The following adds support for RTSP (RFC2326) URLs to the standard
urlparse.py module.
(Augmented by FLD to include rtspu:, specified in the same RFC & OK'd
by Anthony.)

Run ranlib on static libraries. (Should probably have a platform-check
so we don't run ranlib when it's not necessary, ie. on most modern
Unices.)
ihooks.ModuleLoader does not implement reload(mod) correctly:
If mod has already been loaded by ModuleLoader, it has
been returned from a cache. Added an additional parameter
to import_it() to force reloading.
a missing part of the previous checkin message:

Added encoding name attributes to wrapper classes which

The maxsplit functionality in .splitlines() was replaced by the keepends

default list of files from () to None, and explicitly test for None
before defaulting to sys.argv[1:]. This means that if you pass in an
explicit empty list, it will read stdin instead of defaulting to
sys.argv[1:]. This fixes a buglet in the test script (when called
with options but without files, it chokes when it tries to interpret
the options as files).
Lawrence adds: "I suspect that this is a safe change, because I can't
imagine someone actively passing in an empty list when they want
sys.argv used."
I agree.
Instead of assuming that the number process ids of the threads is the
same as the process id of the controlling process, use a copy of the
dictionary and check for changes in the process ids of the threads
from the thread's process ids in the parent process. This makes the
test make more sense on systems which assign a new pid to each thread
(i.e., Linux).
This doesn't fix the other problems evident with this test on Linux.
* '...%s...' % u"abc" now coerces to Unicode just like
string methods. Care is taken not to reevaluate already formatted
arguments -- only the first Unicode object appearing in the
argument mapping is looked up twice. Added test cases for
this to test_unicode.py.

Revise 'copy_file()' and 'copy_tree()' docstrings accordingly.
Remove 'hasattr()' check for 'self.force' from 'make_file()'.
to all commands in the same way. Several Command methods now either expect
'self.force' to be defined, or check if it is defined and assume it's
false if not.
Added code to include source files from 'build_clib' command to default file
list -- currently this won't work, since 'build_clib' doesn't have a
'get_source_files()' method!
his copy of test_contains.py seems to be broken -- the lines he
deleted were already absent). Checkin messages:
New Unicode support for int(), float(), complex() and long().
- new APIs PyInt_FromUnicode() and PyLong_FromUnicode()
- added support for Unicode to PyFloat_FromString()
- new encoding API PyUnicode_EncodeDecimal() which converts
Unicode to a decimal char* string (used in the above new
APIs)
- shortcuts for calls like int(<int object>) and float(<float obj>)
- tests for all of the above
Unicode compares and contains checks:
- comparing Unicode and non-string types now works; TypeErrors
are masked, all other errors such as ValueError during
Unicode coercion are passed through (note that PyUnicode_Compare
does not implement the masking -- PyObject_Compare does this)
- contains now works for non-string types too; TypeErrors are
masked and 0 returned; all other errors are passed through
Better testing support for the standard codecs.
Misc minor enhancements, such as an alias dbcs for the mbcs codec.
Changes:
- PyLong_FromString() now applies the same error checks as
does PyInt_FromString(): trailing garbage is reported
as error and not longer silently ignored. The only characters
which may be trailing the digits are 'L' and 'l' -- these
are still silently ignored.
- string.ato?() now directly interface to int(), long() and
float(). The error strings are now a little different, but
the type still remains the same. These functions are now
ready to get declared obsolete ;-)
- PyNumber_Int() now also does a check for embedded NULL chars
in the input string; PyNumber_Long() already did this (and
still does)
Followed by:
Looks like I've gone a step too far there... (and test_contains.py
seem to have a bug too).
I've changed back to reporting all errors in PyUnicode_Contains()
and added a few more test cases to test_contains.py (plus corrected
the join() NameError).
This patch solves 2 problems of the os module.
1) Bug ID #50 (case-mismatch wiht "environ.get(..,..)" and "del environ[..]")
2) os.environ.update (dict) doesn't propagate changes to the 'real'
environment (i.e doesn't call putenv)
This patches also has minor changes specific for 1.6a
The string module isn't used anymore, instead the strings own methods are
used.
Unix From lines, change the UnixMailbox class so that _search_start()
positions the file *before* the Unix From line instead of after it;
change _search_end() to skip one line before looking for the next From

From lines and squirrels them away in the 'unixfrom' instance variable.
- file_util.py: operations on single files
- dir_util.py: operations on whole directories or directory trees
- dep_util.py: simple timestamp-based dependency analysis
- archive_util.py: creation of archive (tar, zip, ...) files
The functions left in util.py are miscellany that don't fit in any of the
new files.
the Command class from core.py to cmd.py. No other code needs changing
though; distutils.core still provides the Command and Distribution classes,
although indirectly now.
HKEY_* and Reg* names once, rather than having near-duplicate code
in the two import attempts.
Also dropped the leading underscore on all the imported symbols,
as it's not appropriate (they're not local to this module).
* build to "Debug" or "Release" temp directory
* put linker turds (.lib and .exp files) in the build temp directory
* tack on "_d" to extensions built with debugging
* added 'get_ext_libname()' help in putting linker turds to temp dir
Also, moved the code that simplifies None to empty list for a bunch
of options to 'finalize_options()' instead of 'run()'.
Simplified 'Command.get_peer_option()' a tad -- just call 'find_peer()'
to get the peer command object.
Updated 'Command.copy_file()' to take a 'link' parameter, just like
'util.copy_file()' does now.
Added 'Command.make_archive()' to wrap 'util.make_archive()'.
Changes to 'copy_file()':
* added support for making hard links and symlinks
* noted that it silently clobbers existing files when copying, but
blows up if destination exists when linking -- hmmm...
* error message tweak
Added 'base_name' parameter to 'make_tarball()' and 'make_zipfile()'.
Added 'make_archive()' -- wrapper around 'make_tarball()' or
'make_zipfile()' to take care of the archive "root directory".
the command that actually creates "dumb" binary distributions, ie.
tarballs and zip files that you just unpack under <prefix> or <exec-prefix>.
Very limited, but it's a start.
Initial revision is pretty limited; it only knows how to generate "dumb"
binary distributions, i.e. a tarball on Unix and a zip file on Windows.
Also, due to limitations in the installation code, it only knows how to
distribute Python library code. But hey, it's a start.
provided by Distribution.
Cosmetic and error message tweaks.
Simplified 'make_release_tree()':
* extracted 'distutils.util.create_tree()'
* don't have to do hard-linking ourselves -- it's now handled by
'distutils.util.copy_file()' (although the detection of
whether hard linking is available still needs to be factored out)
Removed 'make_tarball()' and 'make_zipfile()' entirely -- their role
is now amply filled by 'distutils.util.make_archive()'.
Simplified 'make_distribution()':
* use Distribution's new 'get_full_name()' method
* use 'make_archive()' instead of if/elif/.../else on the archive format
If a non-tuple sequence is passed as the *arg, convert it to a tuple

Added 'get_outputs()' in preparation for the 'bdist' command, and
'_mutate_outputs()' to support 'get_outputs()'.
in a class attribute 'sub_commands', rather than hard-coded in 'run()'.
This should make it easier to subclass 'install', and also makes it
easier to keep 'run()' and the new 'get_outputs()' consistent.
Added 'get_outputs()' in preparation for the 'bdist' command.
Changed signature of 'build_extensions()': no longer takes the extension
list, but uses 'self.extensions' (just like 'get_outputs()' has to)
Moved call to 'check_extensions_list()' from 'run()' to 'build_extensions()',
again for consistency with 'get_outputs()'.
A host of improvements in preparation for the 'bdist' command:
- added 'get_outputs()' method (all the other improvements were to support
this addition)
- made 'find_package_modules()' and 'find_modules()' return similar
values (list of (package, module, module_filename) tuples)
- factored 'find_all_modules()' out of 'get_source_files()' (needed
by 'get_outputs()')
- factored 'get_module_outfile()' out of 'build_module()' (also needed
by 'get_outputs()')
- various little tweaks, improvements, comment/doc updates
executive summary:
Instead of typing 'apply(f, args, kwargs)' you can type 'f(*arg, **kwargs)'.
Some file-by-file details follow.

simplify varargslist, replacing '*' '*' with '**'
add * & ** options to arglist

define three new opcodes
CALL_FUNCTION_VAR
CALL_FUNCTION_KW
CALL_FUNCTION_VAR_KW

reindent CALL_FUNCTION using four spaces
add handling of sequences and dictionaries using extend calls
fix function import_from to use PyErr_Format
The new filecmp module has an optional argument called use_statcache
which is documented as a true/false value, but used as an tuple index.
This patches replaces the tuple stuff with a good old if- statement,
and also removes a few other tuple pack/unpack constructs (if not
else, this saves a few bytes in the PYC file, and a few microseconds
when using the module ;-).
The attached patch set includes a workaround to get Python with
Unicode compile on BSDI 4.x (courtesy Thomas Wouters; the cause
is a bug in the BSDI wchar.h header file) and Python interfaces
for the MBCS codec donated by Mark Hammond.
Also included are some minor corrections w/r to the docs of
the new "es" and "es#" parser markers (use PyMem_Free() instead
of free(); thanks to Mark Hammond for finding these).
The unicodedata tests are now in a separate file
(test_unicodedata.py) to avoid problems if the module cannot
be found.
This patch fixes the "search" command in imaplib. The problem
was that a search can take multiple arguments, but as defined,
would only accept one.
I have also made changes to the test code at the end to be less
verbose by default, but to accept a verbosity argument.
The robotparser.py module currently lives in Tools/webchecker. In
preparation for its migration to Lib, I made the following changes:
* renamed the test() function _test
* corrected the URLs in _test() so they refer to actual documents
* added an "if __name__ == '__main__'" catcher to invoke _test()
when run as a main program
* added doc strings for the two main methods, parse and can_fetch
* replaced usage of regsub and regex with corresponding re code
we don't know what to do with it when we see it.
Call '_fix_object_args()' and/or '_fix_lib_args()' as appropriate, rather
than just '_fix_link_args()'.
Split '_fix_link_args()' up into '_fix_object_args()' (for use of
'create_static_lib() and link methods) and '_fix_lib_args()' (for the
link methods only).
Attached you find the latest update of the Unicode implementation.
The patch is against the current CVS version.
It includes the fix I posted yesterday for the core dump problem
in codecs.c (was introduced by my previous patch set -- sorry),
adds more tests for the codecs and two new parser markers
"es" and "es#".
these must come from the 'build' command. This means we no longer need
the misconceived 'set_peer_option()' method in Command and, more importantly,
sweeps away a bunch of potential future complexity to handle this tricky
case.
Fix 'Command.set_undefined_option()' to call 'ensure_ready()' rather
than 'finalize_options()' (which is only supposed to be called once,
which is the whole point of 'ensure_ready()').
Added comment to 'set_peer_option()' to remind myself that this method
cannot work and is fundamentally wrong-headed.
this command for a while; this implements roughly the plan cooked up by
Guido, Fred, and me. Seems to strike a nice balance between usability in
the common cases (just set one option), expandability for more types of
files to install in future, and customizability of installation
directories.
This revision isn't completely working: standard and alternate
installations work fine, but there are still some kinks to work out of
customized installations.
Attached you find an update of the Unicode implementation.
The patch is against the current CVS version. I would appreciate
if someone with CVS checkin permissions could check the changes
in.
The patch contains all bugs and patches sent this week and also
fixes a leak in the codecs code and a bug in the free list code
for Unicode objects (which only shows up when compiling Python
with Py_DEBUG; thanks to MarkH for spotting this one).
* improve help strings
* warn if user supplies non-existing directories
* don't try to 'remove_tree()' non-existing directories
* try to remove the build_base after cleanup (but don't do or say
anything if it fails -- this is just in case we made it empty)
option in the 'build_ext' command):
* in ccompiler.py: 'gen_lib_options()' now takes 'runtime_library_dirs'
parameter
* in unixccompiler.py and msvccompiler.py: now pass
'self.runtime_library_dirs' to 'gen_lib_options()', and define
'runtime_library_dir_option()' (although in msvccompiler.py it
blows up with a DistutilsPlatformError right now!)
code generator uses flowgraph as intermediate representation. the old
rep uses a list with explicit "StackRefs" to indicate the target
of jumps.
pyassem converts flowgraph to bytecode, breaks up individual steps of

Re-wrap the docstrings on get_python_inc() and get_python_lib() to be
closer to the "normal" Python style. See GvR's "style guide" on the
essays page (http://www.python.org/doc/essays/).
There should never be a space between a function name and the '(' that
opens the argument list (see the style guide again).
the platform-neutral include dir by default and with Mac support.
Added 'get_python_lib()', inspired by 'get_python_inc()'.
Rewrote 'get_config_h_filename()' and 'get_makefile_filename()'
in terms of 'get_python_inc()' and 'get_python_lib()'.
Changed '_init_nt()' and '_init_mac()' to use 'get_python_inc()' and
'get_python_lib()' for directory names.
When you set a breakpoint on a function with a multi-line argument
list, the breakpoint is actually set on the second line of the
arguments instead of the first line of the body. This patch fixes
that.
fix imports
remove parse functions and visitor code
track name change: Classdef to Class
add some comments and tweak order of visitXXX methods
get rid of if __name__ == "__main__ section
implement it (so far):
* moved filename generation methods into CCompiler base class,
driven by data supplied by implementation classes
* moved a bunch of common code from UnixCCompiler to convenience
methods in CCompiler
* overhauled MSVCCompiler's compile/link methods to look and act
as much as possible like UnixCCompiler's, in order to regularize
both interface and behaviour (especially by using those new
convenience methods)
* replaced build_lib.py with build_clib.py
* renamed the class in build_clib.py
* changed all references to 'build_lib' command in other command classes
when building extensions (uses build_lib's 'get_library_names()' method).
Ensure that the relative structure of source filenames is preserved in
the temporary build tree, eg. foo/bar.c compiles to
build/temp.<plat>/foo/bar.o.
Added 'build_clib' and 'build_temp' options (where to put C libraries
and where to put temporary compiler by-products, ie. object files).
Moved the call to 'check_library_list()' from 'run()' to 'finalize_options()'
-- that way, if we're going to crash we do so earlier, and we guarantee
that the library list is valid before we do anything (not just run).
Disallow directory separators in library names -- the compiled library
always goes right in 'build_clib'.
Added 'get_library_names()', so the "build_ext" command knows what
libraries to link every extension with.
filenames when constructing object filenames, even if output_dir given --
eg. "foo/bar.c" will compile to "foo/bar.o" without an output_dir, and to
"temp/foo/bar.o" if output_dir is "temp".
* 'build_dir' -> 'build_lib', which by default takes its value
straight from 'build_lib' in the 'build' command
* added 'build_temp' and 'inplace' options
* change 'build_extensions()' to put object files (compiler turds) in
'build_temp' dir
* complicated the name-of-extension-file shenanigans in
'build_extensions()' to support "in-place" extension building, i.e.
put the extension right into the source tree (handy for developers)
* added 'get_ext_fullname()', renamed 'extension_filename()' to
'get_ext_filename()', and tweaked the latter a bit -- all to support
the new filename shenanigans
This patch is re: Lucas.Dejonge@awtpl.com.au: [Python-bugs-list] imaplib -
not complying with RFC (PR#218)
Lucas de Jonge reported that the code in imaplib that detects a read-write
to read-only change doesn't comply with RFC 2060.
discussed on c.l.py last January. Specifically:
- more characters allowed in section & option names
- if '=' is used to separate the option & value, the value can be
followed by a comment of the form '\s;'
OptionMenu is modified. Somewhat rewritten and elaborated by myself.
class _setit: The constructor now takes an optional argument
`callback' and stashes this in a private variable. If set, the
__call__() method will invoke this callback after the variable's value
has changed. It will pass the callback the value, followed by any
args passed to __call__().
class OptionMenu: The constructor now takes keyword arguments, the
only one that's legally recognized is `command', which can be set to a
callback. This callback is invoked when the OptionMenu value is set.
Any other keyword argument throws a TclError.
A change in my last patch could, under certain circumstances,
cause a loop if the connection to the server dropped while
waiting for a command completion. I've changed the code to
re-raise the error after possible debugging output.

minor comment nits
old 'dist' command, but the code for dealing with manifests is completely
redone -- and renaming the command to 'sdist' is more symmetric with the
soon-to-exist 'bdist' command.
- removed now (happily) unused second arg
- need to verify results of [].index are correct; for building consts,
need to have same value and same type, e.g. 2 not the same as 2L
(big surprise). new solution is a little less hackish.
Code gen adds a TupleArg instance in the argument slot. The tuple arg
includes a copy of the names that it is responsble for binding. The
PyAssembler uses this information to calculate the correct argcount.
all fix this wacky case: del (a, ((b,), c)), d
which is the same as: del a, b, c, d
(Can't wait for Guido to tell me why.)

Reasons for patches:
1st patch (15,21):
version change
2nd patch (66,72):
This is a patch I found in a Zope product release (quite by accident!).
It relaxes the conditions for matching a literal. I've looked over the
logic, and tested it, and it seems sensible.
3rd patch (117,123):
It appears the quoting matcher was too general, and that the IMAP4
protocol requires characters like ':' in commands to be unquoted.
(This is the patch already sent to Guido.)
4th patch (699,705):
Spelling correction in comment.
5th patch (753,761):
Another patch from the Zope product. It seems that some IMAP4 servers
produce unexpected responses in the middle of valid command/response
sequences. This patch ignores the unexpected responses in this
situation. (How I wish users would send me bug reports with examples!).
last 2 patches: (1015,1028) (1038,1044):
Minor improvements to test code.
- added a number of support methods to generate code just before the
body
- hack protocol for communicating number of args to PyAssembler
fix TryExcept generation for case where exception handler has no body
fix visitAssAttr
add comment about incomplete visitAssName
stop using the ExampleASTVisitor
change script invocation to accept a list of .py files (e.g. Lib/*.py)
named OPTIMIZED, which matches compile.c and makes more sense for
classes
revamp call signature for PythonVMCode.__init__; doesn't really matter
'cuz this code is going to be refactored out of existence
add generateClassCode and modify Func & Lambda generation
add support for nodes Classdef, Keyword,
fix CallFunc to generate right op arg when calling w/ keywords
add ugly hack to properly compute offsets when the same stack ref is
used multiple times
change resolution of local name ops (LOAD_FAST). i think it makes
sense now. if it is an argument or a local var name that it used, it
must be in varnames. if it is a local var name that is used, it must
also be in names
'get_msvc_paths()'.
Renamed '_do_SET()' to 'set_path_env_var()', tweaked docstring, and
cosmetically tweaked code.
Stylistic changes to MSVCCompiler constructor (variable renaming
and type consistency).
* tweak my docstrings
* fix None returns to empty list
* reshuffle responsibilities between '_find_exe()', '_find_SET()', and
the MSVCCompiler constructor -- now the constructor worries about
fetching the version list and determining the most recent one
* added "/W3" compile option
Also, I added/tweaked some docstrings.
NNTPError - derived from Exception, it's the base class for all
other exceptions in this module
NNTPReplyError - what used to be error_reply
NNTPTemporaryError - what used to be error_temp
NNTPPermanentError - what used to be error_perm
NNTPProtocolError - what used to be error_proto
NNTPDataError - what used to be error_data
All the old names are retained for backwards compatibility; they point
to the class that replaces them. Also, any code in this module that
raises an exception, now does so with the exception class.
NNTP.__init__(): Added a new optional argument `readermode', which is
a flag that defaults to false. When set to true, the "mode reader"
command is sent to the NNTP server before user authentication. Reader
mode is sometimes necessary if you are connecting to an NNTP server on
the local machine and intend to call reader-specific comamnds, such as
`group'. If you get unexpected NNTPPermanentErrors, you might need to
set readermode. Patch provided by Thomas Wouters (who include the
standard disclaimer on is patches@python.org submission), and inspired
by Jim Tittsler.
FUNCTION_NAMESPACE. initialize in __init__ and reset in
generateFunctionCode.
replace direct issue of STORE_FAST, STORE_GLOBAL, etc. with call to
storeName; same for loadName and deleteName
the new {store,load,delete}Name methods use the namespace attr and the
local variable stack to determine the correct bytecode to issue
* don't need to mention python<ver>.lib -- it's done by a pragma
* add debug flags for compile and link, and use them
* fix 'link_shared_library()' to pass everything to 'link_shared_object()'
* change filename when shared object with debug info (ugh)
* prints out examples of nodes that are handled by visitor. simply a
development convenience
remove NestedCodeGenerator -- it was bogus after all
replace with generateFunctionCode, a method to call to generate code
for a function instead of a top-level module
fix impl of visitDiscard (most pop stack)
emit lineno for pass
handle the following new node types: Import, From, Getattr, Subscript,
Slice, AssAttr, AssTuple, Mod, Not, And, Or, List
LocalNameFinder: remove names declared as globals for locals
PythonVMCode: pass arg names to constructor, force varnames to contain
them all (even if they aren't referenced)
add -q option on command line to disable stdout
someone who knows Windows/MSVC++ to come along and add the right flags.
Comment noting that 'link_static_lib()' signature is inconsistent with
the other compiler classes (uh-oh!)
VERBOSE setting for the ASTVisitor
add getopt handling for one or more -v args
rename ForwardRef to StackRef, because it isn't necessarily directional
CodeGenerator:
* add assertStackEmpty method. prints warning if stack is not empty
when it should be
* define methods for AssName, UNARY_*, For
PythonVMCode:
* fix mix up between hasjrel and hasjabs for address calculation
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

I did not add docstrings to the methods in profile.py for

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.
It breaks Mailman, it was actually documented in the docstring, so it
was an intentional deviation from the usual del semantics. Let's
document the original behavior in Doc/lib/librfc822.tex.
Changed those two methods to only compile/link if necessary (according
to simplistic timestamp checks).
Added 'output_dir' to 'object_filenames()' and 'shared_object_filename()'.
much breakage (esp. in JPython which holds absolute path names in
co_filename already). This implementation uses os.path.abspath() as a
slightly better way to canonicalize path names. It implements a
cache.
the file that a function is defined on. Non-portable to Windows and
JPython. Instead, new find_function() uses re module on a similar
(simple-minded) pattern.
attributes, etc. Biggest change was to the Distribution constructor
-- it now looks for an 'options' attribute, which contains values
(options) that are explicitly farmed out to the commands. Also,
certain options supplied to Distribution (ie. in the 'setup()' call in
setup.py) are now "command option aliases", meaning they are dropped
right into a certain command rather than being distribution options.
This is handled by a new Distribution class attribute,
'alias_options'.
Various comment changes to reflect the new way-of-thinking.
Added 'get_command_name()' method to Command -- was assuming its
existence all along as 'command_name()', so changed the code that
needs it to call 'get_command_name()'.
now provided (minus the leading underscore) by the ccompiler module.
Fix 'compile()' to return the list of object files generated.
Cosmetic tweaks/delete cruft.
Added big comment about the kludginess of passing 'build_options'
to the link methods and how to fix it.
Added 'gen_preprocess_options()' and 'gen_lib_options()' convenience
functions -- the two cases are very similar for Unix C Compilers and
VC++, so I figured I might as well unify the implementations.
- fix some broken abstract methods
- kludge: add 'build_info' parameter to link methods
- add 'object_name()' and 'shared_library_name()'
- support for MSVCCompiler class on NT/Win95

Urllib makes the URL of the opened file available through the geturl

file: plus the name of the file. This results in an invalid URL if
the file name was relative. This patch fixes this so that the
returned URL is just a relative URL in that case. When the file name
is absolute, the URL returned is of the form file:///absolute/path.

Introduce a new builtin exception, UnboundLocalError, raised when ceval.c
tries to retrieve or delete a local name that isn't bound to a value.
Currently raises NameError, which makes this behavior a FAQ since the same
error is raised for "missing" global names too: when the user has a global
of the same name as the unbound local, NameError makes no sense to them.
Even in the absence of shadowing, knowing whether a bogus name is local or
global is a real aid to quick understanding.
Example:
D:\src\PCbuild>type local.py
x = 42
def f():
print x
x = 13
return x
f()
D:\src\PCbuild>python local.py
Traceback (innermost last):
File "local.py", line 8, in ?
f()
File "local.py", line 4, in f
print x
UnboundLocalError: x
D:\src\PCbuild>
Note that UnboundLocalError is a subclass of NameError, for compatibility
with existing class-exception code that may be trying to catch this as a
NameError. Unfortunately, I see no way to make this wholly compatible
with -X (see comments in bltinmodule.c): under -X, [UnboundLocalError
is an alias for NameError --GvR].
[The ceval.c patch differs slightly from the second version that Tim
submitted; I decided not to raise UnboundLocalError for DELETE_NAME,
only for DELETE_LOCAL. DELETE_NAME is only generated at the module
level, and since at that level a NameError is raised for referencing
an undefined name, it should also be raised for deleting one.]

Problem: rfc822.py in 1.5.2 final loses the quotes around

The fix is to preserve the quotes around a local-part

The correct result is:

__init__.py it isn't read. (Sjoerd just came up with this, so it's
not heavily tested.)
Other (yet unsolved) package problems noted by Sjoerd:
- If you have a package and a module inside that or another package
with the same name, module caching doesn't work properly since the
key is the base name of the module/package.
- The only entry that is returned when you readmodule a package is a
__path__ whose value is a list which confuses certain class browsers

I guess in 1.5.2 a new module, whichdb, was added that attempts to
divine the nature of a database file. This module doesn't know anything
about Berkeley DB v2 files. In v2, Sleepycat added a 12-byte null pad
in front of the old magic numbers (at least for hash and btree files).
I've been using v2 for awhile and upgrading to 1.5.2 broke all my
anydbm.open calls. I believe the following patch corrects the problem.

Tkinter.py in < 3 seconds for me; doctest.py no longer confuses it; no
longer missing methods in PyShell.py; etc. Also captures defs
starting in column 1 now, but ignores them; an interface should be
added so that IDLE's class browser can show the top-level functions
too.

It wasn't hard to speed pyclbr by a factor of 3, and I'll attach an

dramatic speedup!

I noticed while watching (with lsof) my forking SocketServer app running
that I would get multiple processes listening to the socket. For the most
part, this doesn't hurt things, but if you terminate the server, this can
prevent it from restarting because it cannot bind to the port due to any
running children which also have the socket open. The following one-liner
fixes this.

core.py as well: the Command methods that mirror 'copy_file()' and
'copy_tree()' have to pass on their return values.
of the 'install_py' command rather than 'build_py'. Obviously, this
meant that the 'build_py' and 'install_py' modules had to change; less
obviously, so did 'install' and 'build', since these higher-level

commands, and some compilation-related options had to migrate with the
code.

The application where Signum Support uses smtplib needs to be able to
report good error messages to the user when sending email fails. To
help in diagnosing problems it is useful to be able to report the
entire message sent by the server, not only the SMTP error code of the
offending command.
A lot of the functions in sendmail.py unfortunately discards the
message, leaving only the code. The enclosed patch fixes that
problem.
The enclosed patch also introduces a base class for exceptions that
include an SMTP error code and error message, and make the code and
message available on separate attributes, so that surrounding code can
deal with them in whatever way it sees fit. I've also added some
documentation to the exception classes.

empty string (""). The patch fixes the test in the sendmail() method

"""
Mostly I just re-added the SMTPRecipientsRefused exception
(the exeption object now has the appropriate info in it ) [Per had
removed this in his patch --GvR] and tweaked the behavior of the
sendmail method whence it throws the newly added SMTPHeloException (it
was closing the connection, which it shouldn't. whatever catches the
exception should do that. )
I pondered the change of the return values to tuples all around,
and after some thinking I decided that regularizing the return values was
too much of the Right Thing (tm) to not do.
My one concern is that code expecting an integer & getting a tuple
may fail silently.
(i.e. if it's doing :
x.somemethod() >= 400:
expecting an integer, the expression will always be true if it gets a
tuple instead. )
However, most smtplib code I've seen only really uses the
sendmail() method, so this wouldn't bother it. Usually code I've seen
that calls the other methods usually only calls helo() and ehlo() for
doing ESMTP, a feature which was not in the smtplib included with 1.5.1,
and thus I would think not much code uses it yet.

splitunc() parses UNC paths. The contributor of the UNC parsing in
splitdrive() doesn't like it, but I haven't heard a good reason to
keep it, and it causes some problems. (I think there's a
philosophical problem -- to me, the split*() functions are purely
syntactical, and the fact that \\foo is not a valid path doesn't mean
that it shouldn't be considered an absolute path.)

allow using the 'a' flag as a mode for opening a GzipFile. gzip
files, surprisingly enough, can be concatenated and then decompressed;
the effect is to concatenate the two chunks of data.

If a filename on Windows starts with \\, it is converted to a URL
which starts with ////. If this URL is passed to urlparse.urlparse
you get a path that starts with // (and an empty netloc). If you pass
the result back to urlparse.urlunparse, you get a URL that starts with
//, which is parsed differently by urlparse.urlparse. The fix is to
add the (empty) netloc with accompanying slashes if the path in
urlunparse starts with //. Do this for all schemes that use a netloc.
Pathnames of files on other hosts in the same domain
(\\host\path\to\file) are not translated correctly to URLs and back.
The URL should be something like file:////host/path/to/file.
Note that a combination of drive letter and remote host is not
possible.
netloc from the base url as the default netloc for the resulting url
even if the schemes differ.
Once upon a time, when the web was wild, this was a valuable hack
because some people had a URL referencing an ftp server colocated with
an http server without having the host in the ftp URL (so they could
replicate it or change the hostname easily).
More recently, after the file: scheme got added back to the list of
schemes that accept a netloc, it turns out that this caused weirdness
when joining an http: URL with a file: URL -- the resulting file: URL
would always inherit the host from the http: URL because the file:
scheme supports a netloc but in practice never has one.
There are two reasons to get rid of the old, once-valuable hack,
instead of removing the file: scheme from the uses_netloc list. One,
the RFC says that file: uses the netloc syntax, and does not endorse
the old hack. Two, neither netscape 4.5 nor IE 4.0 support the old
hack.
An attempt to execute grid_slaves with arguments (0,0) results in
*all* of the slaves being returned, not just the slave associated with
row 0, column 0. This is because the test for arguments in the method
does not test to see if row (and column) does not equal None, but
rather just whether is evaluates to non-false. A value of 0 fails
this test.
The module cmd requires for each do_xxx command a help_xxx

A note about the previous checkin: I believe it's correct, but I found
something strange: the file Lib/test/audiotest.au in the Python

caused by some conversion program that produced this .au file; I just

File names with "funny" characters get translated wrong by
pathname2url (any variety). E.g. the (Unix) file "/ufs/sjoerd/#tmp"
gets translated into "/ufs/sjoerd/#tmp" which, when interpreted as a
URL is file "/ufs/sjoerd/" with fragment ID "tmp".
Here's an easy fix. (An alternative fix would be to change the
various implementations of pathname2url and url2pathname to include
calls to quote and unquote.
[The main problem is with the normal use of URLs:
url = url2pathname(file)
transmit url
url, tag = splittag(url)
urlopen(url)
]
In addition, this patch fixes some uses of unquote:
- the host part of URLs should be unquoted
- the file path in the FTP URL should be unquoted before it is split
into components.
- because of the latter, I removed all unquoting from ftpwrapper,
and moved it to the caller, but that is not essential
when we create a recursive instance, by setting the class variable
'FieldStorageClass' to the desired class. By default, this is set to
None, in which case we use self.__class__ (as before).
When literal mode is entered it should exit automatically when the
matching close tag of the last unclosed open tag is encountered. This
patch fixes this.
In SimpleHTTPServer.py, the server specified in test() should
be BaseHTTPServer.HTTPServer, in case the request handler should
want to reference the two attributes added by
BaseHTTPServer.server_bind:
self.server_name = hostname
self.server_port = port
There was some Bobo CGI code that wanted access to those attributes.
In CGIHTTPServer.py, the list of acceptable formats is -split-
on spaces but -joined- on commas, resulting in double commas
in the joined text. It appears harmless to my browser but
ought to be fixed anyway.
'A, B, C' -> 'A,', 'B,', 'C,' -> 'A,,B,,C'

situation is treated separately.
Since we were making a copy of the longopts list anyway, we now use
the list() function -- this made it necessary to change all uses of
the local variable (and argument) 'list' to something more meaningful,
i.e., 'opts'.
Also added docstrings (copied from the library manual) and removed the
(now redundant) module comments.
filenames generated are easily predictable, it is possible to trick an
unsuspecting program into overwriting another file by creating a
symbolic link with the predicted name. Fix this by using the
low-level os.open() function with the O_EXCL flag and mode 0700. On
non-Unix platforms, presumably there are no symbolic links so the
problem doesn't exist. The explicit test for Unix (posix, actually)
makes it possible to change the non-Unix logic to work without a
try-except clause.

pdb.py Uses the Breakpoint class so one can enable/disable breakpoints,
set temporary ones, set ignore counts, and conditions. The last
can be set using the 'b' command
b 243 , i>4 ( b 243,i>4 if you are space adverse)
or with the condition command so conditions can be changed
for a particular breakpoint.
Breakpoints are numbered from 1 on, and if a breakpoint is deleted,
the number is not reused. All the breakpoint handling commands
refer to breakpoints by number. To be consistent, the clear command
does so as well, which is the one change from the original pdb that
is not transparent. Thus only the breakpoint command 'b' uses a
line number or file:line or method. You can also give
b whrandom.random and the method will be searched for along
sys.path. This is implemented with an 'egrep' command and so
is not as portable as it might be. [ see lineinfo() and
lineinfoCmd ]
Breakpoints cannot be set at a line that is blank or a '#' comment
or starts a triply quoted comment. This is because I would like
this behavior in my DDD interface and think it reasonable for
pdb as well. It can be removed readily, however as it is all
incorporated in the routine checkline(). If one attempts to
set a breakpoint at a 'def' line, the breakpoint is automatically
moved to the first executable line after the 'def'. This too is
in checkline().
do_EOF() returns zero so typing an end-of-file character as a command
does nothing. 'quit' does the quitting.
The routine defaultFile() is present so as to preserve the current
pdb behavior and yet allow me to override it in pydb.
There's some code in lineinfo() that is probably mainly useful only
for pydb and if you prefer, much up to the comment "Best first guess"
could be removed.
Keith Davidson provided the code for handling $HOME/.pdbrc and
./.pdbrc, and it has been incorporated. He also provided the
alias handling routine. I modified it a bit so it could live
nicely in precmd(). He and I have been in contact; he has the
new pdb (and pydb) with his code incorporated. He also asked
about the possibility of allowing multiple commands on one
line, such as step;step or s;s or with an alias such as
alias ct tbreak %1 ; continue
and since it was so easy, that's in place as well. It's a simple
'split the line at the first ";"' operation and puts the second
half in the command queue (self.cmdqueue). This has the unfortunate
effect of destroying a line like print "i: "+i+"; j: "+j
but either there's a simple way to deal with this, or my attitude
will remain that pdb is a debugger, not a compiler/parser/etc.
An alias like alias 4s s;;s;
will work because the adjacent and trailing ";" act like a <cr> which
repeats the last command. Of course, either s;s;s;s or s;;; would be
a bit more sensible.
The help commands have been updated.
bdb.py now has a class definition called Breakpoint along with
associated methods. There's no reason why this class has to
be there; if you prefer it elsewhere, 'tis easily done.
(Minor reformatting by GvR; e.g. moved Breakpoint's doc string to
proper point.)
cmd.py has incorporated the changes we discussed a couple of weeks ago
(a command queue, returning line from precmd, and stop from postcmd)
and some changes to help that were occasioned because I wanted to
inherit from pdb which inherits from cmd.py and the help routine
didn't look for commands or the associated help deeply enough.
1. use dict.get instead of try/except KeyError
2. if the url scheme is 'http' then avoid the series of
'if var in [someseq]:'. instead, inline all of the code.
3. find = string.find
1) I added a command queue which is helpful to me (at least so far) and
would also allow syntax like 's;s' (step; step) in conjunction with precmd
2) doc_leader allows the derived class to print a message before the help
output. Defaults to current practise of a blank line
3) nohelp allows one to override the 'No help on' message. I need
'Undefined command: "%s". Try "help".'
4) Pass line to self.precmd to allow one to do some parsing: change first
word to lower case, strip out a leading number, whatever.
5) Pass the result of onecmd and the input line to postcmd. This allows
one to ponder the stop result before it is effective.
6) emptyline() requires a if self.lastcmd: conditional because if the
first command is null (<cr>), you get an infinite recursion with the
code as it stands.

problem that randint() was accidentally defined as taking an inclusive

non-integral arguments while I insisted that it be not much slower

convoluted.
Also changed randint() to be implemented through randrange(). This is
a semantic change because old randint() didn't test its arguments for

involve a filesystem path. To that end:
- Changed IOError to EnvironmentError and added a hack which checks
for arg of len 3. When constructed with a 3-tuple, the third item
is the filename and this is squirreled away in the `filename'
attribute. However, for in-place unpacking backwards
compatibility, self.args still only gets the first two items. Added
a __str__() which prints the filename if it is given.
- IOError now inherits from EnvironmentError
- New class OSError which also inherits from EnvironmentError and is
used by the posix module.
Fix the implementation of quote_plus(). (It wouldn't treat '+' in the

Add urlencode(dict) which is handy to create the data for sending a

This affects the 'break' and 'clear' commands and their help
functions. Also added a helper method lookupmodule().
Also:

- Get rid of reference to ancient __privileged__ magic variable.
- Moved all import out of functions to the top.
- When used as a script, check that the script file exists.
not calling self.search(); instead, call self.code.match() directly
and interpret the list of registers it returns directly. This saves
the overhead of instantiating a MatchObject for each hit, basically
inlining search() as well as group(). When a MatchObject is still
needed, one is allocated and reused for the duration of the scan.
In the bbox method of Group (Canvas.py file), you should read
return self.canvas._getints(self._do('bbox'))
instead of
return self._getints(self._do('bbox'))

arbitrary scripts in restricted mode, and it will do the right thing.

1. Convert to using re module
2. Added two new exception classes
a. MissingSectionHeaderError which signals an early parsing
exception when options appear in the file before any section
header. Previously a bogus TypeError was thrown deeper down.
b. ParsingError which collates any non-fatal parsing errors.
ConfigParser.read() will raise this after the entire file was
parsed if any errors occurred during parsing (client could just
catch the exception and continue, because the ConfigParser
instance would still be initialized with the valid data).
(small note: Error.__msg => Error._msg)
3. ConfigParser.__read() now uses re which has the following minor
semantic change: underscore is now allowed in section header and
option name. Also, because of the old regexps, theoretically.
Fixed continuation line bug reported by F. Lundh.
4. It seemed that the old ConfigParser automatically added the option
`name' to every section, which contained the name of the section.

- explain seekable
- when seekable==1, test fp.tell() and set it to 0 if that fails
- support overridable method iscomment(line) to weed out comments
- check for unread() method on file object before trying to seek
And one of my own:
- Add a get() method which behaves like a dictionary's get(); this is
actually implemented by giving getheader() an optional second argument
to specify the default, and aliasing get to getheader.
The 1.5.1 tabnanny.py suffers an assert error if fed a script whose last
line is both indented and lacks a newline:
if 1:
print 'oh fudge' # no newline here:
The attached version repairs that.

- Allow . and - in entity names.
Also fixed an oversight in the previous fix (in one place, [ \t\r\n]
was used instead of string.whitespace).

caching of un-tagged responses. Apologies for its size.
problem was a couple of bugs in the readline implementation.
1. Include the '\n' in the string returned by readline
2. Bug calculating new buffer size in _unread
Also remove unncessary import of StringIO

I think I found a bug in CGIHTTPServer.py. (Does anyone care? :-)
I was trying to use it as the web server for uploading files.
Python CGI scripts (using the CGI module) that worked for other
servers (e.g., Netscape Enterprise server) hang when run from
CGIHTTPServer. The problem is that the content type parameters,
in particular the boundary parameter, were not passed through to
the CGI scripts, thus making the MIME parsing code choke.
My simple-minded fix is:
% diff CGIHTTPServer.py /usr/local/lib/python1.5/CGIHTTPServer.py
137,140c136
< if self.headers.typeheader is None:
< env['CONTENT_TYPE'] = self.headers.type
< else:
< env['CONTENT_TYPE'] = self.headers.typeheader
---
> env['CONTENT_TYPE'] = self.headers.type

and the "key" keyword parameter was used to invoke .go(), use the directory
of the selected file as the stored directory to return to when the same key
is used again. This is useful since the user may well entry at least part
of the path in the filename box instead of doing a lot of clicking around in
the listboxes.
as soon as I change things even just a little bit? :-) Even works
when accessing a password-protected page through the proxy. Prompted
by complaints from, and correct operation verified by, Nigel O'Brian.
wm_title(), etc. The old names (title() etc.) are still defined as
aliases.
This brings all methods up to use the same naming convention: whether
the Tcl syntax is
.window.path.name command subcommand [options]
or
command subcommand .window.path.name [optins]
the Python equivalent is always
windowobject.command_subcommand(options)
calling self.tk.getint() and self.tk.getdouble(), call the globals
getint() and getdouble(), which in turn are just names for the Python
builtins int() and double(). (Making them globals actually save a
dict lookup compared to using the built-in.) The corresponding
methods of class Misc have been changed similarly. (Note that
getboolean() hasn't been changed because there's no Python
equivalent.)
The use of int() and float() has another advantage: if/when Tcl calls
can actually return Tcl objects with other types than string, use of
int() and float() is essential.
not needed to say apply(self.tk.call, t); self.tk.call(t) has the same
effect. This cuts down tremendously on the number of apply() calls
made. No measurable effect, but at the very least it saves the lookup
of apply() in the globals!
be more intelligent when the database already exists (use the module
for the existing file, according to whichdb). Noted in the doc
strings that there doesn't seem to be a different between 'c' and 'n'.
