[issue26466] cannot build python 2.7.11 on AIX

[Michael Felt]

Michael Felt added the comment:

At first I thought it might be a 0x0001 rather than 0x0003 (as I have no idea 
what the additional info is AND that the lines starting with [0] are the Symbol 
0 (zero) you indicate the message.

Also thought it might have been the double listing of some symbols where both 
the 'm' and the 'a4' lines start with 0x (but see those for other .o 
files as well)

And I verified that the .o file (outside the archive) also has '[705]' entries.

Need more guidance. I get neither heads nor tails...

So, dump -t libpython2.7.a snips:

[issue26468] shutil.copy2 raises OSError if filesystem doesn't support chmod

[Vojtěch Pachol]

New submission from Vojtěch Pachol:

`copy2` checks if `os` nodule has `chmod` and then it uses it without thinking. 

On filesystems that doesn't support `chmod` it ends with

OSError: [Errno 95] Operation not supported: 

which is not acceptable since documentation says "copy2() never returns 
failure".

[issue26469] Bug in ConfigParser when setting new values in extended interpolation

[Michael Jacob]

New submission from Michael Jacob:

There seems to be a bug in configparser when setting new values in extended 
interpolation:

python --version
Python 3.5.1

from configparser import ConfigParser, ExtendedInterpolation
c=ConfigParser(interpolation=ExtendedInterpolation)
c.add_section('test')
c.set('test', 'key', 'value')
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python3.5/configparser.py", line 1190, in set
super().set(section, option, value)
  File "/usr/lib/python3.5/configparser.py", line 891, in set
value)
TypeError: before_set() missing 1 required positional argument: 'value'

It works ithout extended interpolation, though.

[issue26469] Bug in ConfigParser when setting new values in extended interpolation

[Michael Jacob]

Michael Jacob added the comment:

My bad.

ConfigParser expects an interpolation object, not a class.

Instead of c=ConfigParser(interpolation=ExtendedInterpolation)

you need to create it with:

c=ConfigParser(interpolation=ExtendedInterpolation())

Sorry about that.

Michael Felt added the comment:

Patched to fp22: vacpp.11.1.0.22.aix53TL7-71.sept2015.ptf.tar.Z

after reinstalling system! to be sure no garbage left around.

Only updates are openSSL/SSH packages; no RPM's installed.

Same error message(s).

Tried compiling ceval.o with -O0 (capt. O, zero) - same messages

[issue26466] cannot build python 2.7.11 on AIX

[Marc-Andre Lemburg]

Marc-Andre Lemburg added the comment:

Does Python 2.7.10 build fine ? If so, then perhaps xlc doesn't
like the computed gotos in ceval.c.

You could try compiling with:

./configure ... --without-computed-gotos ...

to check.

[issue26468] shutil.copy2 raises OSError if filesystem doesn't support chmod

[Eric V. Smith]

Eric V. Smith added the comment:

I agree that copy2 should not fail because chmod fails. Could you please 
provide the entire traceback message when it fails (on both 2.7 and 3.4 or 
3.5)? And what OS are you running on, and what filesystem?

It looks like the error happens because errno=95 (EOPNOTSUPP, probably) isn't 
in the list of errors that _copyxattr catches, while (ENOTSUP=134 on Linux) is.

I think the documentation is also incorrect. Of course copy2 can fail: what 
about out of disk space? I think the documentation is trying to say that copy2 
never fails because it can't preserve metadata. And the wording in the docs 
"copy2() never returns failure" is also odd, it should say "copy2() never 
raises an exception because it cannot preserve file metadata".

[issue26470] Make OpenSSL module compatible with OpenSSL 1.1.0

[Christian Heimes]

New submission from Christian Heimes:

OpenSSL 1.1.0 is changing a lot of internals. Most structs are opaque, RC4 and 
SSLv2 are gone. I've a rough patch in my private repos. I'll submit the patch 
as soon as the code is compatible with OpenSSL 1.0.2, too.

[issue26471] load_verify_locations(cadata) should load AUX ASN.1 to supported trusted certs

[Christian Heimes]

New submission from Christian Heimes:

https://docs.python.org/2/library/ssl.html#ssl.SSLContext.load_verify_locations 
can load certs from a file, a directory or from memory. OpenSSL's loaders for 
cafile and capath load auxiliary data of trusted certs. The custom loader for 
cadata ignores AUX data because it uses PEM_read_bio_X509() instead of 
PEM_read_bio_X509_AUX().

With the recent fix of OpenSSL 1.0.2 
https://github.com/openssl/openssl/commit/a3baa171053547488475709c7197592c66e427cf
 trusted certificates now work again. I propose to change cadata to load trust 
settings, too.

You want tests for the dis.findlabels library? What sort of tests are you

[issue26394] Have argparse provide ability to require a fallback value be present

[Michael Herold]

Michael Herold added the comment:

I have prepared a working patch to sketch how this could be implemented. A 
small example (example.py) shows how this feature can be used to implement a 
fallback to environment variables.

This patch allows Currying of positional arguments (i.e. you can give position 
2 via fallback and provide position 1 via the command line). However, I think 
this might be too confusing and implicit.

Please let me know whether I should prepare a proper patch.

[issue26466] cannot build python 2.7.11 on AIX

[Michael Felt]

Michael Felt added the comment:

wonderful suggestion - it gets the build past that hurdle.

My bad that I had not looked more carefully at configure --help output.

But that brings back another 'issue' I had also seen when verifying 2.7.10. I 
shall look in the bug-list for a related issue (I seem to recall at least one) 
- and request that this one be closed.

Thanks!

[issue25825] AIX shared library extension modules installation broken

[Michael Felt]

Michael Felt added the comment:

FYI: when build and src are the same directory, there is no error message. 
However, when src and build are in seperate directories (e.g.,

build = '.',
src = '../src/python-2.7.11'

the following message occurs MANY times:

unable to execute '../src/python-2.7.11/Modules/ld_so_aix': No such file or 
directory

during configure the file
./Modules/ld_so_aix is 'created' in the build area.

root@x064:[/data/prj/aixtools/python-2.7.11]ls -l Modules/ld*aix*
-rwxr-xr-x   1 root system 6205 Mar 02 16:24 Modules/ld_so_aix

Just guessing, but a line such as:
BLDSHARED="\$(srcdir)/Modules/ld_so_aix \$(CC) 
-bI:\$(srcdir)/Modules/python.exp"

using $(srcdir) is not correct.

Further, a find in $(srcdir) for ld_so_aix returns:
root@x064:[/data/prj/aixtools/python-2.7.11]ls -dl ../src/py*
drwxr-xr-x  17 199  1954   4096 May 23 2015  ../src/python-2.7.10
drwxr-xr-x  17 199  1954   4096 Dec 05 19:47 ../src/python-2.7.11

So, $(srcdir) seems to be wrong, by definition.

For now, I am copying $(srcdir) to $(builddir) to work-around this.

It's unfortunately not so clear from the "minimum Vista" statement that WS2K3 
is excluded, but if you follow the official statement ("supported by 
Microsoft") then you'll see that WS2K3 is no longer covered.

Vista and Windows Server 2008 are the minimum supported versions for 3.5.

[issue26474] Memory leak at malloc_closure.c

[John Snow]

New submission from John Snow:

malloc_closere.c holds a static list of items: free_list.
The items are being allocated in the more_core method using VirtualAlloc / 
mmap. However they never get released.

Here is the allocation code:

#ifdef MS_WIN32
item = (ITEM *)VirtualAlloc(NULL,
   count * sizeof(ITEM),
   MEM_COMMIT,
   PAGE_EXECUTE_READWRITE);
if (item == NULL)
return;
#else
item = (ITEM *)mmap(NULL,
count * sizeof(ITEM),
PROT_READ | PROT_WRITE | PROT_EXEC,
MAP_PRIVATE | MAP_ANONYMOUS,
-1,
0);
if (item == (void *)MAP_FAILED)
return;
#endif

The allocation is only done once. I'm not sure that it can be called a leak. 
Calling the function 1,000 times will not allocate more memory.

[issue23041] csv needs more quoting rules

[Skip Montanaro]

Skip Montanaro added the comment:

Thanks for the update berker.peksag. I'm still not convinced that the csv 
module should be modified just so one user (sorry samwyse) can match the input 
format of someone's Java program. It seems a bit like trying to make the csv 
module type-sensitive. What happens when someone finds a csv file containing 
timestamps in a format other than the datetime.datetime object will produce by 
default? Why is None special as an object where bool(obj) is False?

I think the better course here is to either:

* subclass csv.DictWriter, use dictionaries as your element type, and have its 
writerow method do the application-specific work.

* define a writerow() function which does something similar (essentially 
wrapping csv.writerow()).

If someone else thinks this is something which belongs in Python's csv module, 
feel free to reopen and assign it to yourself.

[issue26448] dis.findlabels ignores EXTENDED_ARG

[Eric Fahlgren]

Eric Fahlgren added the comment:

Barun, take a look at the latest version of the testfindlabels.py, see what you 
think.  If it works for you, maybe move the test function into 
Lib/test/test_dis.py as part of the standard dis module tests.  Still need to 
look at the code that's being tested and find out what cases could cause 
problems and then augment the test to make sure it covers those.

[issue25144] 3.5 Win install fails with "TARGETDIR"

[Claude Chouinard]

Claude Chouinard added the comment:

To solve the problem with the variable TARGETDIR not being initialized, I 
called the installation program from the command shell and added the target dir 
option.

c:\Users\\Downloads>python-3.5.1-amd64.exe TargetDir=c:\Python35

I also us the custom installation option (using the Install Now might not 
work). You should see that the target dir is properly setup to what you have 
specified.

Now it installed without a problem.

[issue23041] csv needs more quoting rules

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

The csv module is already type-sensitive (with QUOTE_NONNUMERIC). I agree, that 
we shouldn't modify the csv module just for one user and one program.

If a standard CVS library in Java (or other popular laguages) differentiates 
between empty string and null value when read from CSV, it would be a serious 
argument to support this in Python. Quick search don't find this.

[issue23041] csv needs more quoting rules

[Berker Peksag]

Berker Peksag added the comment:

I was thinking adding a more flexible API like:

...
spamwriter = csv.writer(csvfile, quoting_callable=lambda field: field is 
not None)
...

But that would require too much change in the csv module (or at least its 
implementation wouldn't be trivial).

I agree that subclassing DictWriter is a much better way to achieve this.
