Jess  added the comment:

Looks like the brackets are fine even in the bracket case Steve mentioned.

@echo off

if NOT DEFINED ABCDEF (
  echo "all good"
)

if NOT DEFINED ABCDE (
  echo "all good2"
)

set ABCDE=

if NOT DEFINED ABCDE (
  echo "sadness"
)

if [%ABCDE%]==[] (
  echo "all good3"
)

set ABCDE=]

if [%ABCDE%] NEQ [] (
  echo "all good4"
)

set ABCDE="]"

if [%ABCDE%] NEQ [] (
  echo "all good5"
)


>demo.bat

[issue36245] PCBuild/build.bat errors, probably from space characters in paths

2019-03-14 Thread Jess


Jess  added the comment:

Alas, "IF NOT DEFINED PYTHON" isn't working - as it's even more possible to get 
into a state where PYTHON="" than it is for a bracket to be in the python name.

Thus, the system would think it declared where we would have created it into an 
actual path otherwise.

[issue36230] Please sort assertSetEqual's output

2019-03-08 Thread Jess


Jess  added the comment:

Good call on the repr(), hadn't noted the "3+4j" issue - __gt__ and __lt__ do 
work for compare there, but not sorted().  *shrug*  Will make sure the solution 
takes that into account in some fashion.

Bit slower as I expected as setting up the windows env has some bits that are 
not entirely happy.

[issue36245] PCBuild/build.bat errors, probably from space characters in paths

2019-03-08 Thread Jess


New submission from Jess :

Have a fix for this that I'll send off shortly.

What I see with the current head (my username was replaced with "Foo Bar" in 
this example:
> Using "C:\Users\Foo 
> Bar\cpython\PCbuild\\..\externals\pythonx86\tools\python.exe" (found in 
> externals directory)
> Bar\cpython\PCbuild\\..\externals\pythonx86\tools\python.exe""=="" was 
> unexpected at this time.

My theory, window's turning:
> C:\Users\Foo Bar
into
> "C:\Users\Foo Bar"
and this is colliding with our use of "%PYTHON%", creating double quotes, or:
> ""C:\Users\Foo Bar""
which, of course:
> if ""C:\Users\Foo Bar""==""
does not make sense as a statement.

[issue35502] Memory leak in xml.etree.ElementTree.iterparse

2018-12-14 Thread Jess Johnson


New submission from Jess Johnson :

When given xml that that would raise a ParseError, but parsing is stopped 
before the ParseError is raised, xml.etree.ElementTree.iterparse leaks memory.

Example:


import gc
from io import StringIO
import xml.etree.ElementTree as etree

import objgraph


def parse_xml():
xml = """
  
  

"""
parser = etree.iterparse(StringIO(initial_value=xml))
for _, elem in parser:
if elem.tag == 'LEVEL1':
break


def run():
parse_xml()

gc.collect()
uncollected_elems = objgraph.by_type('Element')
print(uncollected_elems)
objgraph.show_backrefs(uncollected_elems, max_depth=15)


if __name__ == "__main__":
run()


Output:
[]

Also see this gist which has an image showing the objects that are retained in 
memory: https://gist.github.com/grokcode/f89d5c5f1831c6bc373be6494f843de3

[issue24564] shutil.copytree fails when copying NFS to NFS

2015-07-04 Thread Jess Hamrick

New submission from Jess Hamrick:

shutil.copytree seems to fail when copying files across NFS filesystems. In 
this example (see bug_demo.py), /tmp is a normal ext4 filesystem and the 
current working directory is NFS (version 4). Interestingly, it works fine to 
to copy between ext4 and NFS, just not NFS and NFS (even if it's the same NFS 
mount).

Depending on the specific version of 3.4, there are slightly different errors. 
For 3.4.0:

$ uname -a
Linux compmodels-node 3.13.0-55-generic #94-Ubuntu SMP Thu Jun 18 00:27:10 UTC 
2015 x86_64 x86_64 x86_64 GNU/Linux
$ python3 bug_demo.py

--
Python version info:

os.setxattr(dst, name, value, follow_symlinks=follow_symlinks)
OSError: [Errno 22] Invalid argument: 'demo_files3'

During handling of the above exception, another exception occurred:

  File /usr/lib/python3.4/shutil.py, line 339, in copytree
if why.winerror is None:

And for 3.4.3:

$ uname -a

UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

raise Error(errors)
shutil.Error: [('demo_files', 'demo_files3', [Errno 22] Invalid argument:

This is probably related to https://bugs.python.org/issue17076 and my guess is 
that's also why there is a difference in the error messages between 3.4.0 and 
3.4.3.

[issue24564] shutil.copytree fails when copying NFS to NFS

2015-07-04 Thread Jess Hamrick

Jess Hamrick added the comment:

Some further information: if I run copystat directly on 3.4.3, I get 
essentially the same error as on 3.4.0. So really it only looks like the 
difference is just in how the error is reported:


Traceback (most recent call last):
  File bug_demo.py, line 31, in module
shutil.copystat('demo_files', 'demo_files3')
  File /usr/lib/python3.4/shutil.py, line 213, in copystat
_copyxattr(src, dst, follow_symlinks=follow)
  File /usr/lib/python3.4/shutil.py, line 153, in _copyxattr
os.setxattr(dst, name, value, follow_symlinks=follow_symlinks)
OSError: [Errno 22] Invalid argument: 'demo_files3'


Also, I should mention that I did test this on 2.7 as well, and it is not an 
issue there.

[issue5434] datetime.monthdelta

2010-06-01 Thread Jess Austin

Jess Austin jess.aus...@gmail.com added the comment:

Yeah, the masses have spoken, and their silence is deafening.  I was going to 
downplay the health of the package based on the number of downloads, but then 
I looked at the futures page.  b^)  Seriously, getting this in would require 
a core developer wanting it in, and at this point it seems none do.

On the subject of float operations, while there may be some question about the 
integerness or floatness of timedelta, monthdelta is definitely an integer.  As 
monthdelta already supports multiplication by integers and floor division by 
integers or monthdeltas, I don't see anything missing.  To use monthdeltas with 
floats is to miss the point entirely.

Could you provide some reasoning for such a resolution?  I had thought that

I grant that most people will never see this particular error, but it is an

[issue5516] equality not symmetric for subclasses of datetime.date and datetime.datetime

2010-04-21 Thread Jess Austin

Jess Austin jess.aus...@gmail.com added the comment:

To be systematic, without the patch:

 D(1900, 1, 1)  DT(1900, 1, 1)
False
 D(1900, 1, 1)  DT(1900, 1, 1)
False
 DT(1900, 1, 1)  D(1900, 1, 1)
Traceback (most recent call last):
  File stdin, line 1, in module
TypeError: can't compare DT to D
 DT(1900, 1, 1)  D(1900, 1, 1)
Traceback (most recent call last):
  File stdin, line 1, in module
TypeError: can't compare DT to D


with the patch:

 D(1900, 1, 1)  DT(1900, 1, 1)
True
 D(1900, 1, 1)  DT(1900, 1, 1)
False
 DT(1900, 1, 1)  D(1900, 1, 1)
Traceback (most recent call last):
  File stdin, line 1, in module
TypeError: can't compare DT to D
 DT(1900, 1, 1)  D(1900, 1, 1)
Traceback (most recent call last):
  File stdin, line 1, in module
TypeError: can't compare DT to D


It might seem like the latter behavior is marginally better, but really this is 
just a mess, since a date-datetime comparison TypeErrors in all directions.  I 
appreciate Alexander's more experienced perspective, but it's not obvious to me 
that this problem is insoluble simply due to OOP algebra.  I'm going to keep 
tinkering with this to see if there isn't a way to satisfy his concerns AND fix 
these bugs WITHOUT breaking the established (and admittedly anti-OOP) behavior 
that dates are not equal to datetimes.

(Incidentally, the test I removed still seems to be an arbitrary ad-hoc 
requirement that subclasses of date behave differently than date itself.  I 
don't see how one could rely on this given the other inconsistencies with date 
subclasses, and so violating this in order to fix more serious problems seems 
acceptable.)

I'm reminded of the set and frozenset situation, which seems almost dual to 
this one.  set and frozenset don't inherit from each other, but they do 
compare.  This seems to bite you only when you try to redefine comparison in 
subclasses.

[issue7116] str.join() should be documented as taking an iterable

2009-10-12 Thread Jess Austin

New submission from Jess Austin jess.aus...@gmail.com:

In its __doc__ string and in the documentation, str.join() is described
as taking a sequence.  This is not general enough; it actually takes any
iterable of strings:

 ','.join(str(x) for x in range(5))
'0,1,2,3,4'

Maybe this is a small nit to pick, but it slowed me down for a few
minutes, and I already vaguely remembered that str.join() could handle
iterables.

[issue2706] datetime: define division timedelta/timedelta

2009-03-24 Thread Jess Austin

Jess Austin jess.aus...@gmail.com added the comment:

A comment on the two most recent patches...  For both of these, we can
do the following:

 from datetime import timedelta
 td = timedelta(12)
 td
datetime.timedelta(12)
 td //= 3
 td
datetime.timedelta(4)
 td //= timedelta(2)
 td
2  # CHANGED VARIABLE TYPE!

I think the last operation will trap unsuspecting programmers, and
provide no benefit for the savvy.  There really is no reason to allow an
in-place operation like this to change the type of the variable so
drastically.  (That is, I realize a similar thing could happen with ints
and floats, but it seems worse with timedeltas and ints.)  I feel the
last operation should raise a TypeError, even though it would be quite
valid for a non-in-place operation.

New submission from Jess Austin jess.aus...@gmail.com:

Class names that comply with the CapWords naming convention described in
PEP 8 (http://www.python.org/dev/peps/pep-0008/) are preferred. See the
recent discussion that included the BDFL's recommendations at
http://mail.python.org/pipermail/python-dev/2009-March/086684.html.

Per those recommendations, the attached patch updates every class to
expose a CapWords name to python:

datetime.timedelta  --  datetime.TimeDelta
datetime.date   --  datetime.Date
datetime.tzinfo --  datetime.TZInfo
datetime.time   --  datetime.Time
datetime.datetime   --  datetime.DateTime

In addition, the old lowercase names are reproduced as derived classes,
the methods of which throw PendingDeprecationWarning, and the docstrings
of which advise using the new CapWords class names. The test_datetime.py
unit test is updated to check for proper functionality and for the
presence of the pending deprecation warnings. (This patch relies on the
previously-submitted refactoring patch attached to Issue 5520,
http://bugs.python.org/issue5520.) Various other tests and support files
are updated to use the new CapWords class names.

The current patch still fails one test in test_datetime.py, due to
previously-existing Issue 5516, http://bugs.python.org/issue5516.

This patch includes no documentation updates.

[issue5520] refactor test_datetime.py

2009-03-19 Thread Jess Austin

New submission from Jess Austin jess.aus...@gmail.com:

I've broken out this refactoring from some of the other datetime stuff
I'm doing.  The patch needn't be applied until the other issues that
depend on it are.

[issue5516] equality not reflixive for subclasses of datetime.date and datetime.datetime

2009-03-18 Thread Jess Austin

New submission from Jess Austin jess.aus...@gmail.com:

While the datetime.date and datetime.datetime classes consistently
handle mixed-type comparison, their subclasses do not:

 from datetime import date, datetime, time
 d = date.today()
 dt = datetime.combine(d, time())
 d == dt
False
 dt == d
False
 class D(date):
... pass
... 
 class DT(datetime):
... pass
... 
 d = D.today()
 dt = DT.combine(d, time())
 d == dt
True
 dt == d
False

I think this is due to the premature optimization of using memcmp() in
date_richcompare().

2009-03-11 Thread Jess Austin

Jess Austin jess.aus...@gmail.com added the comment:

This prototype python implementation passes the same tests that the C
implementation in the patch does (modulo import differences).  I'll
probably backport this for 2.x versions.

[issue3107] memory leak in make test (in test list), 2.5.2 not 2.5.1, Linux 64bit

2008-08-15 Thread jess

jess [EMAIL PROTECTED] added the comment:

This appears to be the same issue as in:
30552 months ago test_list on 64-bit platforms

The failing test appears to be test_bigrepeat:

def test_bigrepeat(self):
x = self.type2test([0])
x *= 2**16
self.assertRaises(MemoryError, x.__mul__, 2**16)
if hasattr(x, '__imul__'):
self.assertRaises(MemoryError, x.__imul__, 2**16)

I am experiencing the same symptoms with 64-bit builds on Solaris10 on
an 8gb sparc machine with lots of virtual memory.  The test is
attempting to allocate a list with 4gb elements.  This requires more
space than there is physical memory so the machine starts swapping like
crazy but does not throw an error in 64 bit mode.  In 32 bit, it would
presumabley throw the error because the test has requested more than 4gb
of memory.

In other words Python appears to be working as it should.  In my case I
am not sure that Solaris10 is scanning for virtual memory properly but
that is an entirely different problem.
