[issue18235] _sysconfigdata.py wrong on AIX installations

[Michael Felt]

Michael Felt added the comment:

Ok. I shall rebuild from scratch.

When I do, I start from a "clean" system - only the compiler and my mkinstallp 
helper script.

I am adding the latest zlib for what I would package but I shall forgoe that 
for this test.

Then whatever you changed, you should change back to the way it was.

That's the most important lesson here: never make two or more unrelated
changes to a program unless you have a backup of the working file.

An excellent way to manage this process is by using a revision control
system like Mercurial (hg) or equivalent. But at the very least, whenever
you change a working program, you should confirm it is still working before
making the next change.

In that case I apologise - I gave you the benefit of the doubt though as 
I was only half-suspicious. FWIW, listing specific constructs that must 
be used is often a thing that a tutor would write in an assignment 
(because the purpose of the assignment is to get you to learn about 
those particular constructs). That's what raised the flag for me. Anyway ...

Firstly, there's little point in posting pseudo code if you are 
reporting a specific compiler or run-time error. The errors you get are 
very specific to your code and in some cases are caused by *subtle* 
things in your code. We generally need to see the actual code (or a 
cut-down example) that allows the subtleties to be described to you.

The syntax "foo(spam)" will *call* the function "foo" and pass it the 
value "spam". It doesn't make any sense to _assign a value_ to a 
function call operation (you're effectively trying to assign a value - 
the thing after the '=' - to another value - the return value of the 
function call).


So, what is "mycar"? How do you create it?

In Python, the built-in structure for a group of objects which can be 
dynamically extended with new entries in the way you want is a list. 
Create an empty one with:


mycar = []

or

mycar = list()

Lists have an 'append()' method which will add the parameter it is 
called with to the end of the list object it is called on:


mycar.append(car(model, serial, doors))


You don't have to worry about keeping track of 'count'. Lists will grow 
dynamically as you add things. Use "len(mycar)" to see how many items it 
holds and "for vehicle in mycar:" to step through them all or "mycar[n]" 
to address as specific entry.


From the Python prompt, type "help(list)"

Hope that helps.

You start one client then join before starting the next...

Start them all and push the pointer the resulting process object into a 
collection.
Then use whatever semantics you desire to wait them all...


To me it also looks slightly odd that you're creating a ThreadStats
instance each time around the loop, and the only other reference to it
is to the last one created, and that line's indentation puts it outside
the """if __name__ == '__main__':""" block.

[issue29256] Windows select() errors out when given no fds to select on, which breaks SelectSelector

[Eryk Sun]

Eryk Sun added the comment:

Some WinSock functions are just dispatchers that call a provider function. The 
dispatch table is set up when WinSock (i.e. ws2_32.dll) calls the WSPStartup 
function [1] of a provider DLL (e.g. mswsock.dll). In the case of select(), it 
calls the socket provider's WSPSelect function [2]. It determines the provider 
from the first socket found in the order of readfds, writefds, and exceptfds. 
It fails if there isn't at least one socket from which it can determine the 
provider. Also, given this design, each socket in all three sets has to be from 
the same provider. 

In general, using a dummy socket isn't a good workaround for using select() to 
implement a sleep function. WSPSelect can't be interrupted (or rather, it can 
only be interrupted temporarily to execute an asynchronous procedure call 
that's queued to the thread via QueueUserAPC, after which it resumes waiting). 
If a script uses select() with a dummy socket to sleep on the main thread, the 
user won't be able to cancel the wait with Ctrl+C. It would be better in this 
case if select.select waited on the SIGINT event like the Windows 
implementation of time.sleep.

multiprocessing.Process call blocks other processes from running

[Rodrick Brown]

I'm trying to implement a script that tracks how much space certain
applications are using and send a metric to a statsd service for realtime
analysis however when running this code it nots forking multiple processes
its still running sequential at some point the forking was working but I
can't seem to figure out where I went wrong please advise

I'm just trying to keep track of the growth rate of certain dirs these dirs
have hundreds of thousands of files and take sometime to run I use du as it
runs much faster than os.walk() and it also returns the correct compressed
size on the file system pythons getsize() does not.

Thanks.

You import geopandas as gpd, then import pandas as gpd. So maybe you
think gpd refers to geopandas while it actually refers to pandas. I
don't know geopandas or pandas, but you should check your imports.

[issue29276] HTMLParser in Python 2.7 doesn't recognize image tags wrapped up in link tags

[Ari]

Ari added the comment:

Sorry, it was a false alarm. I had a poorly constructed testcase. I was trying 
to grab all image links from html markup while simultaneously substituting 
image links to somesite.com with links to anothersite.com. I had 
handle_starttag and handle_startendtag defined in my class, but all the image 
processing resided in handle_starttag, and I didn't realize that 
handle_starttag is not automatically called when handle_startendtag is 
executed. So http://somesite.com/small_image.jpg; width="800px" /> 
went straight to handle_startendtag, and it did nothing to process the image 
link because handle_starttag was never called. When I removed 
handle_startendtag definition, I got the link I wanted (but the absense of 
handle_startendtag totally mangled the markup I was trying to produce).

You can find an object's methods in the interactive interpreter with dir()

>>> dir(pointInPoly)

OK, that's quite a lot, but to_file() seems to be a good candidate. Let's 
see what it does:

>>> help(pointInPoly.to_file)
Help on method to_file in module geopandas.geodataframe:

to_file(filename, driver='ESRI Shapefile', schema=None, **kwargs) metod of 
geopandas.geodataframe.GeoDataFrame instance
Write this GeoDataFrame to an OGR data source

A dictionary of supported OGR providers is available via:
>>> import fiona
>>> fiona.supported_drivers

Parameters
--
filename : string
File path or file handle to write to.
driver : string, default 'ESRI Shapefile'
The OGR format driver used to write the vector file.
schema : dict, default None
If specified, the schema dictionary is passed to Fiona to
better control how the file is written.

The *kwargs* are passed to fiona.open and can be used to write
to multi-layer data, store data within archives (zip files), etc.

Looks good, run it:

>>> pointInPoly.to_file("point_in_poly")

No error. Does it round-trip?

>>> pointInPoly == gpd.GeoDataFrame.from_file("point_in_poly")

Ouch, unfortunately not. Upon further inspection:

Looks like column names are either corrupted or limited to 10 characters by

here's the first hit for 'shp file column name limit' on a popular search 
engine:

http://gis.stackexchange.com/questions/15784/how-to-bypass-10-character-limit-of-field-name-in-shapefiles

I'm out of this now.

[issue26865] Meta-issue: support of the android platform

[Xavier de Gaye]

Xavier de Gaye added the comment:

Current status:
---

Available using the pyona build system [1]:
  * Cross compilation of Python for a given Android API level and architecture 
with android-ndk-r13b.
  * Cross compilation of third party extension modules (currently as a patch).
  * Interactive interpreter with curses and readline support, the Android adb 
(remote) shell is used to start the interpreter on the qemu emulator or a 
device connected with USB.
  * Remote debugging with gdb and support of the python-gdb module.
  * The adb shell is used to start a run of the test suite on the emulator or a 
device.

To be defined for the support of the Android platform:
  * Support starting with which Python release ?
 sys.getandroidapilevel() has been defined in Python 3.7 by issue 28740, so 
unless this enhancement is backported to 3.6 the first release to support 
Android could be 3.7.
  * What is the supported Android API level(s) [2] ?
 Level 21 is the first to provide a reliable wide character support.
 Level 24 is the most recent api level currently supported by the NDK and 
is the first where the adb shell is run as the 'shell' user instead of as 
'root' and as a consequence, where the test suite must now cope with Android 
SELinux non permitted operations (hard link, mkfifo, mknod, bind on a unix 
socket).
  * On which architecture(s) ?
 The x86 platform is useful for testing and debugging as it runs fast on 
the Android qemu emulator.
 AFAIK the armv7 platform is still one of the most widespread Android 
platforms [3] [4].
  * Building with which NDK version ?
 The next android-ndk-r14 release is the first to provide "Unified 
headers", see issue #29040.
  * The buildbots run the test suite on the Android qemu emulator or on a 
device or both ?

Test suite results on the Android qemu emulator:
  test_builtin is excluded in all the tests - test_asyncio is excluded on 
armv7-android-api-21.
  x86 platform (duration: about 27 minutes, to be compared with 26 minutes when 
the test suite is run natively on the same laptop).
api 21: success
api 24: success
  armv7 platform (duration: about 410 minutes. Without the latest released 
libffi-3.2.1 that does not build on armv7).
api 21: success
api 24: success

Remaining issues:
1) Blocker issues:
  test_builtin:
issue #13886: failure when test_readline is run before test_builtin.
  This problem is not specific to Android.
  test_asyncio:
issue #26858: android: setting SO_REUSEPORT fails
  Failure only on armv7 at api 21.

2) Issues with a patch tested successfully on x86 and armv7 at Android api 21 
and 24:
  Build:
issue #28833: cross compilation of third-party extension modules.
  PermissionError raised at api 24:
test_eintr test_genericpath test_pathlib test_posix test_shutil test_stat
  issue #28759: access to mkfifo, mknod and hard links is controled by 
SELinux MAC on Android
test_os:
  issue #29180: skip tests that raise PermissionError in test_os (non-root 
user on Android)
test_tarfile:
  issue #29181: skip tests that raise PermissionError in test_tarfile 
(non-root user on Android)
test_socketserver:
  issue #29184: skip tests of test_socketserver when bind() raises 
PermissionError (non-root user on Android)
test_distutils:
  issue #29185: test_distutils fails on Android api 24
test_asyncio:
  issue #28684: [asyncio] bind() on a unix socket raises PermissionError on 
Android for a non-root user.
  Miscellaneous:
test_asyncio:
  issue #28562: test_asyncio fails on Android upon calling getaddrinfo().
test_readline:
  issue #28997: test_readline.test_nonascii fails on Android.
test_curses:
  issue #29176: /tmp does not exist on Android and is used by 
curses.window.putwin()

3) Enhancement issues:
  issue #26855: android: add platform.android_ver().
  issue #27659: Prohibit implicit C function declarations.
  issue #29040: building Android with android-ndk-r14.

4) Languishing issues:
  issue #22724: byte-compile fails for cross-builds.
  issue #27606: Android cross-built for armv5te with clang and '-mthumb' 
crashes with SIGSEGV or SIGILL.
  issue #26852: add the '--enable-sourceless-distribution' option to configure.
  issue #27640: add the '--disable-test-suite' option to configure.

[issue29277] os.getcwd failing on LOFS share

[miniflow]

New submission from miniflow:

I am calling os.getcwd and am occasionally seeing failures inside my program.  
This is not due to files missing as the files on the share are static.

Eror is:

[Errno 2] No such file or directory

Which is definitely not the case.

Can any sort of trace be done at the time of failure to detect if the issue is 
with python or the OS?

System is running Debian inside of an Illumos LX zone.

and when I ran your code I got the very error that you saw. There are many

It looks like there are no intersections in your data.
With the proviso that I've learned about the library only today I think you 
should get an empty result set rather than the ValueError.
Here's a way to reproduce the error (?) with the data provided in the 
project:

import geopandas
from geopandas import gpd

world = gpd.read_file(gpd.datasets.get_path('naturalearth_lowres'))
cities = gpd.read_file(gpd.datasets.get_path('naturalearth_cities'))
countries = world[['geometry', 'name']]

def find(items, name):
# didn't find the idomatic way quickly, so
for index, n in enumerate(items["name"]):
if n == name:
return items[index:index+1]
raise ValueError

berlin = find(cities, "Berlin")
paris = find(cities, "Paris")
germany = find(countries, "Germany")

print(gpd.sjoin(berlin, germany))
print(gpd.sjoin(paris, germany)) # ValueError
 
$ python demo.py
geometry name_left  index_right  \
175  POINT (13.39960276470055 52.52376452225116)Berlin   41   

name_right  
175Germany  

[1 rows x 4 columns]
Traceback (most recent call last):
  File "demo.py", line 20, in 
print(gpd.sjoin(paris, germany)) # ValueError
  File "/home/peter/virt/geopandas/lib/python3.4/site-
packages/geopandas/tools/sjoin.py", line 57, in sjoin
r_idx = np.concatenate(idxmatch.values)
ValueError: need at least one array to concatenate
$

I suggest that you file a bug report.

[issue29276] HTMLParser in Python 2.7 doesn't recognize image tags wrapped up in link tags

[Ari]

New submission from Ari:

The following code produces incorrect results under Python 2.7.13. One would 
expect it to print 2 lines, "Encountered a start tag: a" and "Encountered a 
start tag: img". Yet it prints only "Encountered a start tag: a".

from HTMLParser import HTMLParser
class MyHTMLParser(HTMLParser):
def handle_starttag(self, tag, attrs):
print 'Encountered a start tag: %s' % tag
parser = MyHTMLParser()
parser.feed('http://somesite.com/large_image.jpg;>http://somesite.com/small_image.jpg; width="800px" />')


Python 3.5.2 produces correct results on the same input and prints the expected 
"Encountered a start tag: a" and "Encountered a start tag: img".

from html.parser import HTMLParser
class MyHTMLParser(HTMLParser):
def handle_starttag(self, tag, attrs):
print("Encountered a start tag:", tag)
parser = MyHTMLParser()
parser.feed('http://somesite.com/large_image.jpg;>http://somesite.com/small_image.jpg; width="800px" />')

[issue18235] _sysconfigdata.py wrong on AIX installations

[David Edelsohn]

David Edelsohn added the comment:

Michael, you need to build from scratch. The values are set and tweaked in 
various phases of configure and then written to _sysconfigdata.py for 
installation.

The values in the file reflect the values used during the build, but many of 
them are not used in an installed version of Python.

Three important phases are:

1) Building modules in the tree during the build process.
2) In-tree testing of build module feature.
3) Building and installing modules with an installed version of Python.

The initial configuration scripts must match the location where the export 
files will be installed. And the _sysconfigdata.py definitions used to build 
external modules in an installed version of Python must refer to the proper 
location.

All of the pieces are interconnected and must be tested in a wholistic manner. 
A partial rebuild does not test the impact of the patch.

[issue23407] os.walk always follows Windows junctions

[Craig Holmquist]

Craig Holmquist added the comment:

Here's a new patch:  now, _Py_attribute_data_to_stat and Py_DeleteFileW will 
just use the IsReparseTagNameSurrogate macro to determine if the file is a 
link, so os.walk etc. will know not to follow them.  os.readlink, however, will 
only work with junctions and symbolic links; otherwise it will raise ValueError 
with "unsupported reparse tag".

This way, there's a basic level of support for all name-surrogate tags, but 
os.readlink only works with the ones whose internal structure is (semi-) 
documented.

I don't think that is a problem. The function uses a number of floating point 
operations producing inexact intermediate values. There is not an evidence that 
the proposed code produces more accurate value.

I did that in the patch for issue 28188. The focus of the patch is to add bytes

[issue29270] super call in ctypes sub-class fails in 3.6

[Eryk Sun]

Eryk Sun added the comment:

Resolving this would be straightforward if we could use a subclass for the 
swapped type, but ctypes simple types behave differently for subclasses. A 
simple subclass doesn't automatically call the getfunc to get a converted value 
when returned as a function result, struct field, or array index.

TclError in Terry's example is raised because Tcl script has unpaired braces. 
You should add "{" at the end of TIX_LIBRARY.

Here is working exploit:

$ TIX_LIBRARY="/dev/null}; exec python3 -m this >spoiled; set x {"  python3 -c 
"from tkinter.tix import Tk; Tk()"

It creates the file "spoiled" in current directory containing The Zen of Python.

[issue29270] super call in ctypes sub-class fails in 3.6

[Nick Coghlan]

Nick Coghlan added the comment:

Yeah, re-using Python-level method objects in different types is genuinely 
invalid when combined with __class__ or zero-argument super(), as there's no 
way to make the __class__ closure refer to two different classes at runtime - 
it will always refer back to the original defining class.

And while ctypes could be updated to do the right thing for functions, 
classmethod, staticmethod, abstractmethod, property, etc, there's nothing 
systematic it can do that would work for arbitrary descriptors (any of which 
may have a zero-argument-super-using method definition hidden inside their 
internal state).

I confess I'm going to have to read a bit more about Python internals before I 
can understand Eryk's analysis (this is my first encounter with "cell

I'm not too concerned about the state being broken with reversed endianness; I 
don't think that's going to affect any of my use-cases in the near future, but 
it's certainly useful to know in case it does come up.

[issue29125] Shell injection via TIX_LIBRARY when using tkinter.tix

[Terry J. Reedy]

Terry J. Reedy added the comment:

In the original code, python interpolates tixlib into the string sent to and 
executed by tcl exec.  With the patch, tcl exec does the interpolation.  Not 
knowing anything in particular about tcl's exec, I found a value for tixlib 
that appears to validate Serhiy's claim that tcl exec does not rescan.

C:\Users\Terry>py -3.5
Python 3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:18:55) [MSC v.1900 64 bit 
(AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter as tk
>>> tka = tk.Tk().tk
>>> txlib =  '} python -c "print(999)"'
>>> tka.setvar('TIX_LIBRARY', txlib)
>>> tka.eval('global autopath; lappend auto_path {%s}' % txlib)
Traceback (most recent call last):
  File "", line 1, in 
_tkinter.TclError: extra characters after close-quote

>>> tka.eval('global autopath; lappend auto_path $TIX_LIBRARY')
'{C:\\Programs\\Python35\\tcl\\tcl8.6} C:/Programs/Python35/tcl C:/Programs/lib 
C:/Programs/Python35/tcl/tk8.6 C:/Programs/Python35/tcl/tk8.6/ttk \\}\\ 
python\\ -c\\ \\"print(999)\\"'

I don't understand exactly why (or when) TclError is raised. but it is only 
raised when python does the interpolation.  And for this string, only when '}' 
is present.  Without the '}', there is no exception and the interpolated string 
is simply appended, as with the new $TIX_LIBRARY code.

test_tix, such as it is, passes with the patch.  So unless I missed something 
the patch appears to be both safe and useful.

I guess (!) that somehow the well known trusted CA (= "Certificate authority")
certificates are incomplete on your machine.

Certificate verification works as follows:
a certificate is always signed by a certificate authority ("CA");
for a certificate to be trusted, the signing CA must be trusted.
There may be several trust steps but finally, there must be
some "CA" that you are trusting "without further proof".
The certificates of those "CA"s are somewhere stored on your machine.

Apparently, the "https" servers you have problems with
are using a CA which is not declared trusted on your machine
(by installing the appropriate certificate at the correct place).

[issue29006] 2.7.13 _sqlite more prone to "database table is locked"

[Armin Rigo]

Armin Rigo added the comment:

larry: unless someone else comments, I think now that the current status of 
3.5.3 is fine enough (nothing was done in this branch, and the problem I 
describe and just fixed in PyPy can be left for later).

The revert dd13098a5dc2 needs to be itself reverted in the 2.7 branch.

You mean href values that start with "http://;?
While you can do that with a callback

def check_scheme(href):
return href is not None and href.startswith("http://;)

for a in soup.find_all("a", href=check_scheme):
print(a["href"])

or a regular expression

import re

for a in soup.find_all("a", href=re.compile("^http://;)):
print(a["href"])

why not keep things simple and check before printing? Like

for a in soup.find_all("a"):
href = a.get("href", "") # empty string if href is missing
if href.startswith("http://;):
print(href)

Re: Running Virtualenv with a custom distlib?

I would try to run "virtualenv" in a virtual environment with a "distlib"
seemingly to fulfill the "virtualenv" requirements but in fact be under
your control (e.g. set up via "python setup.py develop").

I do not know whether the virtual environment mentioned above can
be set up via "virtualenv" itself (that would be the easiest thing).
If not, I would install "python" from source and tweak its "site-packages"
as necessary.

[issue29270] super call in ctypes sub-class fails in 3.6

[Nick Coghlan]

Nick Coghlan added the comment:

Eryk's diagnosis sounds right to me, and the suggested patch will get this back 
to working as well as it did in Python 3.5.

However, it's worth noting that that state itself was already broken when it 
comes to zero-argument super() support on the type definition with reversed 
endianness:

```
>>> import ctypes as ct
>>> class SuperText(ct.c_uint32):
... def __repr__(self):
... return super().__repr__()
... 
>>> SuperText.__ctype_le__(1)

>>> SuperText.__ctype_be__(1)
Traceback (most recent call last):
  File "", line 1, in 
  File "", line 3, in __repr__
TypeError: super(type, obj): obj must be an instance or subtype of type
```

The apparently nonsensical error message comes from both the original type and 
the type with swapped endianness having the same representation:

>>> SuperText.__ctype_le__

>>> SuperText.__ctype_be__
