[issue13120] Default nosigint option to pdb.Pdb() prevents use in non-main thread

2011-11-27 Thread Ilya Sandler 

Ilya Sandler  added the comment:

I think stuff like this can only be tested out-of-process.

So I added an out-of-process test to test_pdb.py. The test passes with the 
fixed pdb.py. (and fails with the original one).

Patch for the test attached.

[issue13405] Add DTrace probes

2011-11-27 Thread Jesús Cea Avión 

Jesús Cea Avión  added the comment:

New 3.3 version.

- Use the cached UTF8 of strings inside the interpreter, instead of managing 
the details manually.

- "line" probe works, even with "computed-gotos" optimization.

The only missing feature now, compared with 2.7 version, is the "stack" helper. 
Working on it.

[issue13443] wrong links and examples in the functional HOWTO

2011-11-27 Thread A.M. Kuchling 

A.M. Kuchling  added the comment:

Yes, linking to the functional module was to point people to a module that 
might be useful, even if it's not in the stdlib.  A numeric processing or 
socket handling HOWTO would also pretty much have to link to non-stdlib 
sources.  The purpose of documentation is to be useful to the reader, so I 
think if linking to something external would be reasonably useful, we should do 
it.

Another motivation for linking was to provide alternative explanations; if the 
reader finds the Functional HOWTO boring or too superficial or too complicated, 
maybe an alternative discussion like Mertz's "Text Processing" will fit their 
brain better.  (At least until those alternative sources become so outdated 
that they're useless...)

Windows has dup(), but no fstat().

[issue13487] inspect.getmodule fails when module imports change sys.modules

2011-11-27 Thread Amaury Forgeot d'Arc 

Amaury Forgeot d'Arc  added the comment:

You are certainly right, but I wonder how this can happen.
Are there modules which import something just by looking at them?
Or is is some race condition due to another running thread?

[issue13475] Add '-p'/'--path0' command line option to override sys.path[0] initialisation

2011-11-27 Thread Matthew Woodcraft 

Matthew Woodcraft  added the comment:

The proposed --nopath0 option is something I've wished I had in the past.

If this is added, it would be good if it could be given a single-letter form 
too, because it's an option that would be useful in #! lines (they don't 
reliably support using more than one command-line argument, and single-letter 
switches can be combined while long-form ones can't).

[issue11732] Skip decorator for tests requiring manual intervention on Windows

2011-11-27 Thread Catalin Iacob 

Catalin Iacob  added the comment:

To avoid messing with system registry settings it sounds like 
WerRegisterRuntimeExceptionModule could also work, at least on Windows7 
http://msdn.microsoft.com/en-us/library/windows/desktop1/dd408167%28v=VS.85%29.aspx

There could be a dll which would do nothing when receiving the crash report for 
expected crashes (test_capi and test_faulthandler). 
WerRegisterRuntimeExceptionModule doesn't exist in the headers of the SDK that 
comes with VS2008 but it could be retrieved at runtime with GetProcAddress. 
It's more work than the registry setting but seems cleaner since it avoids 
changing system settings.

+dummy_fd = dup(fd);
+if (dummy_fd < 0)
+return 0;
+close(dummy_fd);

Why not use fstat() instead (does Windows have fstat()? And dup()?).

+@unittest.skipIf(os.name == 'nt', "test needs POSIX semantics")
+def test_no_stdin(self):

It would maybe be more direct with skipUnless(os.name == 'posix').

Finally, it's not that important, but it could maybe be possible to factorize 
the code, i.e. make a helper function that takes a list of streams and defines 
the preexec() function and code to test those streams, and then just call:

def test_no_stdin(self):
out, err = self._test_with_closed_streams(['stdin'])
[...]

def test_no_streams(self):
out, err = self._test_with_closed_streams(['stdin', 'stdout', 'stderr'])
[...]

[issue13491] sqlite3 code adjustments

2011-11-27 Thread Nebelhom 

New submission from Nebelhom :

The code examples for the sqlite3 library were in some cases non-functional.

With the help of Petri Lehtinen from core-mentorship, the following fixes are 
suggested.

NOTE: Last issue is not resolved yet, but suggestions have been made. Could you 
please review and decide what to do. The remaining issues have suggested fixes 
in the patch.

---

Connection.create_function(name, num_params, func)

Creates a user-defined function that you can later use from within SQL 
statements under the function name name. num_params is the number of parameters 
the function accepts, and func is a Python callable that is called as the SQL 
function.

The function can return any of the types supported by SQLite: bytes, str, 
int, float and None.

Example:

import sqlite3
import hashlib

def md5sum(t):
return hashlib.md5(t).hexdigest()

con = sqlite3.connect(":memory:")
con.create_function("md5", 1, md5sum)
cur = con.cursor()
cur.execute("select md5(?)", ("foo",))
print(cur.fetchone()[0])

This script raises error:

Traceback (most recent call last):
  File "sqlexample.py", line 12, in 
cur.execute("select md5(?)", ("foo",))
sqlite3.OperationalError: user-defined function raised exception

When md5sum is then run separately, the following traceback is given

>>> md5sum(("foo",))
Traceback (most recent call last):
  File "", line 1, in 
  File "sqlexample.py", line 7, in md5sum
return hashlib.md5(t).hexdigest()
TypeError: object supporting the buffer API required


Suggested fix:

Change ("foo") to (b"foo")



Connection.text_factory¶

Using this attribute you can control what objects are returned for the TEXT 
data type. By default, this attribute is set to str and the sqlite3 module will 
return Unicode objects for TEXT. If you want to return bytestrings instead, you 
can set it to bytes.

For efficiency reasons, there’s also a way to return str objects only for 
non-ASCII data, and bytes otherwise. To activate it, set this attribute to 
sqlite3.OptimizedUnicode.

You can also set it to any other callable that accepts a single bytestring 
parameter and returns the resulting object.

See the following example code for illustration:

import sqlite3

con = sqlite3.connect(":memory:")
cur = con.cursor()

# Create the table
con.execute("create table person(lastname, firstname)")

AUSTRIA = "\xd6sterreich"

# by default, rows are returned as Unicode
cur.execute("select ?", (AUSTRIA,))
row = cur.fetchone()
assert row[0] == AUSTRIA

# but we can make sqlite3 always return bytestrings ...
con.text_factory = str
cur.execute("select ?", (AUSTRIA,))
row = cur.fetchone()
assert type(row[0]) == str
# the bytestrings will be encoded in UTF-8, unless you stored garbage in the
# database ...
assert row[0] == AUSTRIA.encode("utf-8")

# we can also implement a custom text_factory ...
# here we implement one that will ignore Unicode characters that cannot be
# decoded from UTF-8
con.text_factory = lambda x: str(x, "utf-8", "ignore")
cur.execute("select ?", ("this is latin1 and would normally create errors" +
 "\xe4\xf6\xfc".encode("latin1"),))
row = cur.fetchone()
assert type(row[0]) == str

# sqlite3 offers a built-in optimized text_factory that will return 
bytestring
# objects, if the data is in ASCII only, and otherwise return unicode 
objects
con.text_factory = sqlite3.OptimizedUnicode
cur.execute("select ?", (AUSTRIA,))
row = cur.fetchone()
assert type(row[0]) == str

cur.execute("select ?", ("Germany",))
row = cur.fetchone()
assert type(row[0]) == str

The code example returns the following error traceback

Traceback (most recent call last):
  File "sqlexample.py", line 23, in 
assert row[0] == AUSTRIA.encode("utf-8")
AssertionError

Suggested fixes:
- #Create table... -> removed as not used
- all "assert type ... str" changed to "assert type ... bytes"
- # we can also implement... code block removed
- add ":meth:`[parameters]` needs to be a bytes type otherwise a TypeError will 
be raised." to the doc

-
Cursor.executemany(sql, seq_of_parameters)

Executes an SQL command against all parameter sequences or mappings found 
in the sequence sql. The sqlite3 module also allows using an iterator yielding 
parameters instead of a sequence.

Here’s a shorter example using a generator:

import sqlite3

def char_generator():
import string
for c in string.letters[:26]:
yield (c,)

con = sqlite3.connect(":memory:")
cur = con.cursor()
cur.execute("create table characters(c)")

cur.executemany("insert into characters(c) values (?)", ch

[issue13490] broken downloads counting on pypi.python.org

2011-11-27 Thread holger krekel 

New submission from holger krekel :

Seems like pypi.python.org does not properly maintain download counters 
anymore, at least for a few packages i looked at like pytest,execnet,tox,nose.
