[issue16146] MIMEApplication cannot access

[R. David Murray]

R. David Murray added the comment:

Ah, I'd forgotten python2 email used the lazy importer.  We dropped that in 
python3.

I don't think that I want to fix this, since you have to do the import in 
python3 anyway.

[issue16146] MIMEApplication cannot access

[Yinian Sun]

Yinian Sun added the comment:

These MIME except MIMEApplication can be directly accessed.

>>> import email
>>> email.mime.Text

>>> email.mime.Application
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'module' object has no attribute 'Application'

According to Lib\email\__init__.py, it uses LazyImporter to deal with name 
mapping from new-style names to old-style name, and the _MIMENAMES list just 
doesn't include 'Application'. This causes the behavior inconformity. As 
issue1424065, the MIMEApplication added after other MIME class.

[issue812369] module shutdown procedure based on GC

[Neil Schemenauer]

Neil Schemenauer added the comment:

It's been quite a long time since I played with this patch so my memory might 
be a bit fuzzy.  As I recall, it sounds good in theory but in practice it 
doesn't really work.  One of the core problems is that many extension modules 
keep references to Python objects in global or static variables.  These 
references keep pretty much everything alive and prevent GC cleanup of modules.

So, a necessary condition to this working is to get rid of those references and 
use the new module struct facility introduced by Martin.  That would be a huge 
amount of work but I think should be the long term goal.

[issue15631] Python 3.3/3.4 installation issue on OpenSUSE lib/lib64 folders

[Skip Montanaro]

Skip Montanaro added the comment:

I applied the OpenSUSE patch to the current cpython tip (3.4a0), rebuilt, then 
reinstalled.  I verified that sys.path contains directories which contain 
"lib64".  I can import the time module now, which failed before applying the 
patch.

The patch didn't apply perfectly (two chunks were slightly offset), so I 
generated a new patch, which is attached.

It's been awhile since I did anything with bug reports.  I tweaked a few 
fields.  Let me know if I muffed anything.

[issue16145] Abort in _csv module

[Roger Binns]

Roger Binns added the comment:

(APSW author here).  I haven't ported to the new Python 3.3 Unicode handling 
yet but it is on my todo list.  The PEPs and doc said the C API would remain 
backwards compatible.  The APSW code supports Python 2.3 onwards.

SQLite APIs support both UTF-8 and UTF-16.  Py_UNICODE_SIZE is used to select 
between two code paths - if 2 then the UTF-16 APIs are used and if 4 then a 
UTF-8 conversion is made and those APIs used.  Python 3.3 makes Py_UNICODE_SIZE 
meaningless and will be quite a bit of work to integrate as a third branch.

It should be noted that at no point is there any dependence of the underlying 
bytes/pointer living a long time.  They are only used at the point which data 
needs to be transferred between Python types and SQLite APIs (both ways) and 
not held outside of that period.

"In general APSW does not look ready for the Python 3.3 Unicode implementation."

I bet that most Python modules implemented in C use the "legacy" (old) Unicode 
API (Py_UNICODE*). Python 3.3 must call PyUnicode_READY() everywhere (where the 
new API is used to get attribute of a string, ex: PyUnicode_GET_LENGTH).

It's a new requirement.

Good point. The main hint I find is here:

http://docs.python.org/py3k/whatsnew/3.3.html#deprecated-functions-and-types-of-the-c-api

But you have to click through to:

http://docs.python.org/py3k/c-api/unicode.html#PyUnicode_FromUnicode

PEP 393 on the other hand has this paragraph:

"Extension modules using the legacy API may inadvertently call PyUnicode_READY,
 by calling some API that requires that the object is ready, and then continue
 accessing the (now invalid) Py_UNICODE pointer. Such code will break with this
 PEP. The code was already flawed in 3.2, as there is was no explicit guarantee
 that the PyUnicode_AS_UNICODE result would stay valid after an API call (due
 to the possibility of string resizing). Modules that face this issue need to
 re-fetch the Py_UNICODE pointer after API calls; doing so will continue to
 work correctly in earlier Python versions."

[issue16147] Rewrite PyUnicode_FromFormatV() to use the _PyUnicodeWriter API

[STINNER Victor]

New submission from STINNER Victor:

Attached patch rewrites PyUnicode_FromFormatV():
 * simplify the code: replace 4 steps with one unique step. PyUnicode_Format() 
has the same design. It avoids to store intermediate results which require to 
allocate an array of pointers in the heap.
 * use the _PyUnicodeWriter API for speed (and its convinient API): 
overallocate the buffer to reduce the number of "realloc()"
 * Implement "width" and "precision" in Python, don't rely on sprintf(). It 
avoids to need of a temporary buffer allocated on the heap: only use a small 
buffer allocated in the stack.
 * Detect integer overflow when parsing width and precision, as done in 
PyUnicode_Format()
 * Add _PyUnicodeWriter_WriteCstr() function
 * Split PyUnicode_FromFormatV() into smaller functions: add 
unicode_fromformat_arg(). It requires to copy vargs using Py_VA_COPY: without 
Py_VA_COPY, the function does crash. I don't understand why.
 * Inline parse_format_flags(): the format of an argument is now only parsed 
once, it's no more needed to have a subfunction.
 * Optimize PyUnicode_FromFormatV() for characters between two arguments: 
search the next "%" and copy the substring in one chunk, instead of copying 
character per character.
 * Replace "prec too big" with "precision too big" in error messages

_tescapi.test_string_from_format() is 20% faster with the patch according to 
timeit. I don't know how to write better benchmarks because PyUnicode_FromV() 
is not exposed in Python. I wrote a benchmark using ctypes to call the 
function, but it looks like the ctypes overhead is too high.

I wrote the patch to simplify the code, but it may be faster thanks to the 
_PyUnicodeWriter API and some optimizations implemented in the patch.

[Andrew Svetlov]

Andrew Svetlov added the comment:

I'm ok with your patch if it will be applied to 3.2 etc and after that new 
issue will fix Windows problem.
BTW, the patch fails for 3.2 and 3.3 but works for 3.4

[issue16145] Abort in _csv module

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

How do you get values to write? Most likely, the problem has nothing to do with 
csv module, but written values are broken. Possible error in sqlite module, or 
in any conversion function, or in you APSW C-code. Can you dump this values 
before sending to writerow?

[issue16145] Abort in _csv module

[Stefan Krah]

Stefan Krah added the comment:

In general APSW does not look ready for the Python 3.3 Unicode
implementation. Example: src/statementcache.c:217

Py_UNICODE *out;
PyObject *res=PyUnicode_FromUnicode(NULL, size);


Python 3.3 docs:

"If the buffer is NULL, PyUnicode_READY() must be called once the string 
content has been filled before using any of the access macros such as 
PyUnicode_KIND()."


The abort() in the traceback occurs precisely because PyUnicode_READY()
hasn't been called, so I'm closing this as invalid.

[issue16146] MIMEApplication cannot access

[R. David Murray]

R. David Murray added the comment:

This is by design.  If you want to load the application module, you have to do 
so explicitly:

  import email.mime.application

This is similar to the way many other packages are organized.  An __init__ file 
importing a submodule is the (relatively) exceptional case rather than the 
common case.  This is so that applications that do not need particular 
submodules do not incur the performance and memory hit of importing those 
submodules implicitly.

[issue16145] Abort in _csv module

[Roger Binns]

Roger Binns added the comment:

I'm the APSW author.  You do not need SQLite installed - APSW's setup can fetch 
the current SQLite and use it privately not affecting the rest of the system.

An easier way of testing is:

  python3 setup.py fetch --sqlite --version 3.7.14 build_ext --inplace --force

Create test.sql with these contents

  .output output_file
  .mode csv
  select 3, '4';

Then run:

  env PYTHONPATH=. python3 tools/shell.py
  .read test.sql

The actual code where the problem happens does the following:

- Create a StringIO
- Initialize csv.writer using the StringIO
- Write one row with two values (this is when the crash happens in Python 3.3 
on the first write)
- Copy the current contents of the StringIO to the actual output file changing 
encoding as needed
- Truncate StringIO and seek back to offset zero ready for the next line

The relevant code is in tools/shell.py in the output_csv function.  Writing 
just that sequence of code above doesn't result in the assertion.  valgrind 
doesn't show any problems either (using pydebug, without pymalloc and all the 
freelists set to zero).

A stack trace is here:  https://code.google.com/p/apsw/issues/detail?id=132#c4

If not using a debug/nopymalloc build then you get a crash happening later.

[issue16115] test that executable arg to Popen() takes precedence over args[0] arg

[Chris Jerdonek]

Chris Jerdonek added the comment:

Actually, I was still working on this.  I had assigned it to myself.

+p = subprocess.Popen(["nonexistent","-c",'import sys; sys.exit(42)'],
+executable=sys.executable, cwd=python_dir)

The test for the executable argument should really test the executable argument 
independent of the cwd argument.  Also, it would be better if the test uses a 
valid args[0] to demonstrate precedence.  I had prepared a test but did not 
upload it yet, because I also wanted to add an accompanying clarification to 
the docs which I am still preparing.  Reopening.

[issue16146] MIMEApplication cannot access

[yinian1992]

New submission from yinian1992:

I have a python 2.7.3 installation both on Debian 6 and Windows 7. And under 
both environment email.mime.application cannot access.

>>> email.mime.application
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'module' object has no attribute 'application'

It seems that the import list of email module's __init__.py doesn't include it.

[issue16144] misleading sentence in reference/import

[Manuel Pégourié-Gonnard]

New submission from Manuel Pégourié-Gonnard:

I find the following sentences, from import.rst, section "Finders and loaders", 
misleading: "Python includes a number of default finders and importers. One 
knows how to locate frozen modules, and another knows how to locate built-in 
modules." in that one may think frozen comes before built-in, while the 
converse is true.

Attached is a patch with a hopefully clearer version. While at it, the patch 
also turns into links the references to PEPs in the introduction.

[Brett Cannon]

Brett Cannon added the comment:

R. David Murray added the comment:
