'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

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.

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]

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.]

Other (yet unsolved) package problems noted by Sjoerd:
- If you have a package and a module inside that or another package

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.
appreciably. Triple-quoted strings no longer confuse it, nor nested
classes or defs, nor comments starting in column 1. Chews thru
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
experimental patch for that (experimental because barely tested). Uncomment
the new "String" stuff and it will deal with strings correctly (pyclbr
currently ignores the possibility), but that slows it down a lot. Still
faster in the end than current pyclbr, but-- frankly --I'd rather have the
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.
meaningful return values: respectively, whether the copy was done, and
the list of files that were copied. This meant some trivial changes in
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 must make options available to control the lower-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.
The constructor will now raise an exception if it cannot connect to
the SMTP server.
The data() method will raise an SMTPDataError if it doesn't receive
the expected 354 code in the middle of the exchange.
According to section 5.2.10 of RFC 1123 a smtp client must accept "any
text, including no text at all" after the error code. If the response
of a HELO command contains no text self.helo_resp will be set to the
empty string (""). The patch fixes the test in the sendmail() method
so that helo_resp is tested against None; if it has the empty string
as value the sendmail() method would invoke the helo() method again.
The code no longer accepts a -1 reply from the ehlo() method in
sendmail().

I pondered the change of the return values to tuples all around,

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,

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.

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

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

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.

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,

Also added docstrings (copied from the library manual) and removed the

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

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.

for pydb and if you prefer, much up to the comment "Best first guess"

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.

associated methods. There's no reason why this class has to

cmd.py has incorporated the changes we discussed a couple of weeks ago

didn't look for commands or the associated help deeply enough.

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.

current version of tkColorChooser. I've attached an up-
dated version for 1.5.2.
DOS (as well as OS/2). I presume that making a call to putenv() with
a lowercase key will actually do the right thing. I know this is so
on Windows/DOS, and I expect it is so OS/2 -- but the old OS/2 code
didn't assume this. (I don't know if the person who provided the OS/2
patch was clueless or just didn't care about DOS and Windows.)
Also ripped out the support for pickling -- as of 1.5, this is no
longer needed to make pickling work.
I did some bugfixes, and fixed a major problem with the esmtp suport (I
think the person who did that part misunderstood RFC1869) Some of the
interface fer esmtp-related things has changed as a result.
I also added some documentation to the SMTP class' docstring.
choice(range(start, stop, step)) but faster. This addresses the
problem that randint() was accidentally defined as taking an inclusive
range (how unpythonic).
The code is longish because Tim Peters insisted that it reject
non-integral arguments while I insisted that it be not much slower
than randint(); the compromise satisfies both but is somewhat
convoluted.
Also changed randint() to be implemented through randrange(). This is
a semantic change because old randint() didn't test its arguments for
validity. (It also makes randrange() win any contest with randint()
:-)
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
original data right.)
Add urlencode(dict) which is handy to create the data for sending a
POST request with urlopen().
according to an idea by Harri Pasanen (but with different syntax).
This affects the 'break' and 'clear' commands and their help
functions. Also added a helper method lookupmodule().
Also:
- Try to import readline (important when pdb is used from/as a script).
- 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'))
(2) Made the test script a bit fancier -- you can now use it to run
arbitrary scripts in restricted mode, and it will do the right thing.
(The interactive mode is still pretty lame; should integrate this with
code.interact().)
