[issue2090] __import__ with fromlist=[''] causes double initialization of modules
New submission from hauser:
This construction:
__import__( 'pkg', {}, {}, [''] )
Will cause double initialization of package 'pkg', once with name 'pkg'
and second one with name 'pkg.' (trailing dot). Implementation tries to
import subpackage of 'pkg' with empty name, and imports the same package
twice.
This kind of construction is used as a hacky way to obtain exact module
instead of top-level module in return value. It is a hack, but should
not cause this kind of side effects.

[issue2078] CSV Sniffer does not function properly on single column .csv files

When attempting to sniff() the dialect for the attached .csv file,
csv.Sniffer.sniff() returns an unusable dialect:
import csv
file = open('listB2Mforblast.csv', 'r')
dialect = csv.Sniffer().sniff(file.readline())
file.seek(0)
file.readline()
file.seek(0)
reader = csv.DictReader(file, dialect)
reader.next()
Traceback (most recent call last):
File stdin, line 1, in module
File /soft/bioinfo/linux/python-2.5/lib/python2.5/csv.py, line 93,
in next
d = dict(zip(self.fieldnames, row))
TypeError: zip argument #1 must support iteration
However, this works fine:
file.seek(0)
reader = csv.DictReader(file)
reader.next()
{'Sequence': 'AALENTHLL'}
If I use a 2 column file, sniff() works perfectly.
It only seems to have a problem with single column .csv files (which are
still .csv files in my opinion)
Thanks for looking into this.

[issue1682] Move Demo/classes/Rat.py to Lib/fractions.py and fix it up.
Nick Coghlan added the comment: I mentioned my dislike of the classmethod-staticmethod change on the python-checkins list, but given the lack of response there, I figure I should bring it up here. It is well established that the way to implement an alternate constructor in Python is to write a classmethod. This means the alternate constructor will behave in a way similar to __new__: invocation via a subclass will result in an instance of that subclass rather than of the base type. Now, this does usually mean the parent class is placing certain expectations on the signature of the subclass constructor. However, this is a pretty common Python idiom, and a lot friendlier than coercing the result to the base type. It makes the common case (constructor signature unchanged or at least compatible) simple, while still permitting the rarer case of changing the signature in an incompatible way (by overriding the class methods as well as the __new__ and __init__ methods) If you want to make this more convenient for users that do want to subclass and change the constructor signature, the expected interface can be factored out to a single method, similar to the way it is done for collections.Set and its _from_iterable class method (i.e. if a Set subclass constructor doesn't accept an iterable directly, it can just override _from_iterable to adapt the supplied iterable to the new interface). -- nosy: +ncoghlan __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1682 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Reproducibility: At least 10% on Windows XP Professional SP2, P4 3.20GHz, 2.00GB RAM, when running the attached module, threadpool.py. (Running with Python 2.5.1). Unfortunately I cannot get the attached test case to crash on Linux or Solaris. However, executing this code as part of our Python test framework (see context below), with Python 2.4.1, what looks like the same crash produced the following backtrace: #0 reset_exc_info (tstate=0x8254458) at /tools/src/python/python-2.4.1/Python/ceval.c:2861 tstate = (PyThreadState *) 0x8254458 frame = (PyFrameObject *) 0x0 tmp_type = (PyObject *) 0x82a3a18 tmp_value = (PyObject *) 0x0 tmp_tb = (PyObject *) 0x2 #1 0x080a9b56 in PyEval_EvalFrame (f=0x82a38ac) at /tools/src/python/python-2.4.1/Python/ceval.c:2490 stack_pointer = (PyObject **) 0x82a3a18 next_instr = (unsigned char *) 0x81d4f1e opcode = 136660056 oparg = 0 why = WHY_RETURN err = 0 x = (PyObject *) 0x810d940 v = (PyObject *) 0x81d4f1e w = (PyObject *) 0xf6462fc0 u = (PyObject *) 0xf642ec50 t = (PyObject *) 0x0 stream = (PyObject *) 0x0 fastlocals = (PyObject **) 0x82a39f8 freevars = (PyObject **) 0x82a3a18 retval = (PyObject *) 0x810d940 tstate = (PyThreadState *) 0x8254458 co = (PyCodeObject *) 0xf6134c60 instr_ub = -1 instr_lb = 0 instr_prev = -1 first_instr = (unsigned char *) 0x81d4d9c | names = (PyObject *) 0xf63d762c consts = (PyObject *) 0xf6134c2c #2 0x080aa263 in PyEval_EvalCodeEx (co=0xf6134c60, globals=0xf6075824, locals=0x0, args=0x82c1080, argcount=2, kws=0x82c1088, kwcount=0, defs=0xf6414298, defcount=1, closure=0x0) at /tools/src/python/python-2.4.1/Python/ceval.c:2730 co = (PyCodeObject *) 0xf6134c60 globals = (PyObject *) 0x8254458 locals = (PyObject *) 0x82a38ac args = (PyObject **) 0x82c1080 argcount = 2 kws = (PyObject **) 0x82c1088 kwcount = 0 defs = (PyObject **) 0xf6414298 defcount = 1 closure = (PyObject *) 0x0 f = (PyFrameObject *) 0x82a38ac retval = (PyObject *) 0x0 fastlocals = (PyObject **) 0x82a39f8 freevars = (PyObject **) 0x82a3a18 tstate = (PyThreadState *) 0x8254458 x = (PyObject *) 0x82a38ac u = (PyObject *) 0x82a38ac #3 0x080acda7 in fast_function (func=0xf613e8b4, pp_stack=0xe951f3dc, n=2, na=2, nk=0) at /tools/src/python/python-2.4.1/Python/ceval.c:3643 func = (PyObject *) 0x82a38ac co = (PyCodeObject *) 0x8254458 globals = (PyObject *) 0xf6075824 argdefs = (PyObject *) 0x8254458 d = (PyObject **) 0xf6414298 nd = 1 #4 0x080ab08a in call_function (pp_stack=0xe951f3dc, oparg=1) at /tools/src/python/python-2.4.1/Python/ceval.c:3568 oparg = 136660056 na = 2 nk = 0 n = 2 pfunc = (PyObject **) 0x82c1080 func = (PyObject *) 0xf613e8b4 x = (PyObject *) 0x8172f54 w = (PyObject *) 0x82a38ac #5 0x080a9338 in PyEval_EvalFrame (f=0x82c0f1c) at /tools/src/python/python-2.4.1/Python/ceval.c:2163 sp = (PyObject **) 0x82c1088 stack_pointer = (PyObject **) 0x82c1088 next_instr = (unsigned char *) 0x81f58cc \001q\225 opcode = 136660056 oparg = 1 why = WHY_NOT err = 0 x = (PyObject *) 0x82a37ec v = (PyObject *) 0x81f58cc w = (PyObject *) 0xf6444de0 u = (PyObject *) 0xf642ec50 t = (PyObject *) 0x1 stream = (PyObject *) 0x0 fastlocals = (PyObject **) 0x82c1068 freevars = (PyObject **) 0x82c1080 retval = (PyObject *) 0x0 tstate = (PyThreadState *) 0x8254458 co = (PyCodeObject *) 0xf618c920 instr_ub = -1 instr_lb = 0 instr_prev = -1 first_instr = (unsigned char *) 0x81f57f4 | names = (PyObject *) 0xf63a484c consts = (PyObject *) 0xf6164a1c #6 0x080aa263 in PyEval_EvalCodeEx (co=0xf618c920, globals=0xf5d658ac, locals=0x0, args=0x827d690, argcount=1, kws=0x827d694, kwcount=1, defs=0xf5d77e78, defcount=2, closure=0x0) at /tools/src/python/python-2.4.1/Python/ceval.c:2730 co = (PyCodeObject *) 0xf618c920 globals = (PyObject *) 0x8254458 locals = (PyObject *) 0x82a38ac args = (PyObject **) 0x8136f18 argcount = 1 kws = (PyObject **) 0x827d694 kwcount = 1 defs = (PyObject **) 0xf5d77e78 defcount = 2 closure = (PyObject *) 0x0 f = (PyFrameObject *) 0x82c0f1c retval = (PyObject *) 0x0
[issue2076] xmlrpclib closes connection after each call
New submission from Erno Kuusela: xmlrpclib is using the old HTTP and HTTPS classes from httplib which are to quote the docstring, Compatibility classes with httplib.py from 1.5. and force the use of HTTP 1.0. This prevents connection reuse and pipelining. Attacked is some code we are using as a workaround. Is the xmlrpclib in the standard library required to keep compatibility with old python versions? -- components: Library (Lib) files: transport.py messages: 62309 nosy: erno severity: normal status: open title: xmlrpclib closes connection after each call versions: Python 2.5 Added file: http://bugs.python.org/file9414/transport.py __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue2076 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
