roland rehmnert [EMAIL PROTECTED] added the comment: We had to be careful how we should handle this. http://effbot.org/zone/element-iterparse.htm A note on this site says following : Note: The tree builder and the event generator are not necessarily synchronized; the latter usually lags behind a bit. This means that when you get a “start” event for an element, the builder may already have filled that element with content. You cannot rely on this, though — a “start” event can only be used to inspect the attributes, not the element content. For more details, see this refhttp://mail.python.org/pipermail/xml-sig/2005-January/010838.html/ref. I do understand that it might be so that elem.text is undefined at start.

[issue214033] re incompatibility in sre
Jeffrey C. Jacobs [EMAIL PROTECTED] added the comment:
The duplicate zero-or-one repeat operator bug described in this issue
originally no longer exists in python 2.6.
However, Trent Mick brings up a fair point in that expressions of the
form (x*)? generate an error (issue 1456280) when internally the '?'
should be passively stripped from the expression by the Python Regular
Expression Compiler because it is redundant. The same goes for
expressions of the form (x*)* (issue 2537). Also, there is a problem
with expressions of the form (x*){n,m} (issue 1633953), since the x*
matches as much as it can, and thus it sees the range repeat operation
as redundant -- in this case I think the range repeat should have the
effect of matching (x*)(x*)(x*)... n to m times, but since the first
time matches everything, the subsequent matches all match zero-width
expressions following the first one. I am tracking all of these issues
under Item 33 of Issue 2636.
The are the 3 known redundant repeat issues, but this one, the zero-or-
one followed by zero-or-one is AFAICT fixed in python 2.6 as the
expression originally listed now passes compile.

The prime motivation it that it's easy to either forget the '\Z' or to use '$' instead, which both cause subtle bugs.

[issue1456280] Traceback error when compiling Regex
Jeffrey C. Jacobs [EMAIL PROTECTED] added the comment:
This is another version of the redundant repeat issue defined in issues
2537 and 1633953 and although not described by the original report for
issue 214033, the comments further down that issue also describe a
similar situation.
In this case, the problem arises from the '[(](?Pkey[^)]*)?[)]'
portion of your regexp code because you have a zero-or-more repeat
repeated zero-or-one times, which in the current version of python
causes this error. Technically, the outer zero-or-one operator ('?') is
redundant and you can eliminate it, but this IMHO should not cause the
error listed below and I will look into a solution in issue 2636.

[issue4112] Subprocess: Popen'ed children hang due to open pipes
New submission from Boye Høverstad [EMAIL PROTECTED]:
subprocess.Popen.wait() hangs if you have spawned multiple child
processes that do not terminate until their standard input is closed
('cat' is example of such a process). This happens on POSIX platforms.
I'm using Python 2.5.1, but I believe the issue is present in the SVN
trunk version of subprocess as well.
Here is a test program:
--
import subprocess, sys
p1 = subprocess.Popen(cat, bufsize=0, stdin=subprocess.PIPE)
p2 = subprocess.Popen(cat, bufsize=0, stdin=subprocess.PIPE)
p1.stdin.close()
ret = p1.wait()
print sys.stderr, Child 1 wait completed with ret, ret
p2.stdin.close()
ret = p2.wait()
print sys.stderr, Child 2 wait completed with ret, ret, Bye bye
--
The call to p1.wait() will never return. If p2.wait is called first,
the program terminates cleanly.
p1 never terminates because p1.stdin is duplicated in the (second) child
process when the parent process forks as part of the call to p2 =
subprocess.Popen(). The line p1.stdin.close() thus has no effect.
I am not sure whether this is a bug or deliberate design, but the
behavior above seems a bit weird to me, and it took me quite some time
to figure out what happened. However, the proposed fix below of course
has side effects that may be undesirable.
wait() will not hang if the close on exec flag is set on the
subprocess pipes. Conveniently, the method _set_cloexec_flag already
exists to do this, so the fix amounts to calling this from
Popen._get_handles:
elif stdin == PIPE:
p2cread, p2cwrite = os.pipe()
self._set_cloexec_flag(p2cwrite)
The last line is the added one, similar lines must be added for stdout
and stderr.
Alternatively, the test program above will terminate cleanly if
p1._set_cloexec_flag(p1.stdin) is added before the creation of p2.

[issue2751] Regression for executing packages
Nick Coghlan [EMAIL PROTECTED] added the comment: (Adding some additional details regarding the reasons why this became an error again in 2.6) The ImportError when attempting to execute a package was lost during the conversion from the C-based implementation in 2.4 to the runpy module based implementation as part of 2.5. Packages really aren't meant to be executable with -m - it gets messy since__init__ is able to modify the way module lookups work within the package, and there are various other package specific details related to relative imports that don't apply when dealing with normal modules. That said, executing -m pkg.__init__ with Python 2.6 will generally have the same effect as doing -m pkg with Python 2.5 (it keeps the import machinery happy since the package gets imported normally first, and so long as pkg.__init__ can cope with being first imported normally for the package initialisation and then run as '__main__' it should also work as a script). Anyone that would like to see the ability to execute packages restored should feel free to create a RFE issue for it, but it would take a fairly detailed analysis of the import system to convince me that doing so doesn't break any of the interpreter internals. ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue2751 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4114] struct returns incorrect 4 byte float
TD22057 [EMAIL PROTECTED] added the comment: I'm receiving a 32 bit floating point number encoded in binary format. The correct value for that number is 1.8183e-7 which can be expressed in single precision just fine. Given that the number in the binary encoding is 1.8183e-7, I expected to get that back, not 1.818300034983622e-07 (which is NOT the closest double precision number to the actual single precision number). After doing some experiments, I think the problem is a basic fact of life in C code which is that casting that single precision value to a double precision one does not specify what happens in the extra digits. So I'm getting garbage in the extra digits when the struct module C code casts the single to a double. The problem is that C doesn't assume that the non-precise digits are zero. Since this is a function of the underlying C language, I'll withdraw the bug.

[issue4114] struct returns incorrect 4 byte float

The problem is not from Python but from your FPU during the conversion

#include stdio.h

{
float f;
double d;
d = 1.8183;
printf(d=%.20f\n, d);
f = (float)d;
d = (double)f;
printf(f=%.20f\n, f);
printf(d=%.20f\n, d);
return 0;
}
Result:
d=1.81832736 # ok
f=1.8183877380371094 # 64-32: loose precision
d=1.8183877380371094 # 32-64: no change

[issue4117] missing update() in _Screen.setup() of Lib/turtle.py
New submission from Gregor Lingl [EMAIL PROTECTED]: In Lib/turtle.py _Screen.setup() needs a final update() call in order to ensure, that immediately following calls of window_width() or window_height() return correct values.

[issue3727] poplib module broken by str to unicode conversion
STINNER Victor [EMAIL PROTECTED] added the comment: Ooops, my previous patch was wrong (startswith = not startswith). I tested python trunk test for poplib: with minor changes, all tests are ok except tests using SSL. I get a select.error: (9, 'Bad file descriptor') from asyncore. So I tried to synchronize python3 ssl with python2 trunk, but it depends on python2 trunk version of the socket module and this module is very complex and hard to port to python3. About EBADF error from select(), it may comes from missing makefile() method of the ssl socket wrapper.

[issue4118] Built-in compile() and ast module doc issues
New submission from Terry J. Reedy [EMAIL PROTECTED]: From docs.python.org 2.6: Compile the source into a code or AST object. 3.0: Compile the source into a code object. Add 'or AST ' to the latter. Both: Refer to the _ast module documentation there is none, docs only for the ast module, but see below Both: for information on how to compile into and from AST objects. This sentence should at least have 'and from AST ' deleted. The information on 'from' is given in the previous sentence. Both: source can either be a string or an AST object. The ast doc adds nothing. A modified abstract syntax tree can be compiled into a Python code object using the built-in compile() function. The remainder of the sentence could be replaced by the shorter To compile into an AST object, import ast and pass ast.PyCF_ONLY_AST as a flag. This could be followed by See ast module documentation for more. In the ast doc, both say: An abstract syntax tree can be generated by passing _ast.PyCF_ONLY_AST ... That should be ast, not _ast; the existence of the shadow C version is a CPython implementation detail. In the parse() doc lines, 'PyCF_ONLY_AST' should, I think, have the 'ast' prefix as the former will not work unless one does 'from ast import PyCF_ONLY_AST' (or '... import *'). Back to compile(): 2.6 (and before): When compiling a string with multi-line statements... 3.0 Caveats missing The first, about '\n' versus '\r\n' still applies. print (compile(def f():\r\n pass #haha,'','exec')) #fails print (compile(def f():\n pass #haha,'','exec')) # succeeds The second, at least for 2.5.2 and 3.0c1 (and I presume for 2.6), only applies, it seems, based on testing, if the last line consists only of a comment. In the second example above, putting '#haha' on a separate line fails. See: 'compile' built-in function failures when missing EOL http://bugs.python.org/issue1479099 I am not sure what to suggest, but a warning that is nearly always a false alarm confuses and lulls. -- assignee: georg.brandl components: Documentation messages: 74712 nosy: georg.brandl, tjreedy severity: normal status: open title: Built-in compile() and ast module doc issues versions: Python 2.6, Python 2.7, Python 3.0 ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4118 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue3727] poplib module broken by str to unicode conversion
STINNER Victor [EMAIL PROTECTED] added the comment: New version: - fix SSL: self.file contains the SSL socket and not the raw socket! - upgrade test_poplib.py from Python trunk poplib should be refactored to reuse the new IO library. But I don't know how to build a TextIO wrapper for a socket. Using TextIO, it would be possible to remove newline (CR/LF) and unicode encoding/decoding code.

[issue3727] poplib module broken by str to unicode conversion
STINNER Victor [EMAIL PROTECTED] added the comment:
New version:
- remove duplicate methods of POP3_SSL()
- use makefile('r', encoding=self.encoding) to get a nice text
wrapper with universal newline
- remove newline conversion (done by TextIOWrapper)
Finally my patch removes more code in poplib.py than it adds :-D I
like such patch.
Python3 new I/O library rocks!
