[issue23670] Modifications to support iOS as a cross-compilation target
Russell Keith-Magee added the comment: This new patch (20150504.diff) adds support for running the Python test suite The new patch is standalone, and contains everything in the previous patch. An XCode project (Tools/iOS-test) has been added to the source tree; this project contains bootstrap C code to start and run the full Python regression test suite. There's also a new target in the iOS/Makefile meta-buildfile - make test - which will compile a debug version of the Python framework, and install it into the iOS-test project. Getting the test suite to run has revealed one major limitation of the iOS platform - system calls like fork, exec*, and spawn* don't work. The OS calls *exist* at an API level - but if you use them, they either crash, or they lock up the device while you wait for a subprocess that will never execute. This makes sense considering the platform itself - there's no such thing as a background process in iOS; background tasks are very heavily sandboxed. A number of other minor problems have been identified as a result of running the full test suite; they have been addressed in the patch. The test suite still has 5 failures on the simulator. I'm investigating the cause of these failures. There's a couple of more failures on a physical device - 13 failures in total. These device-specific failures appear to be largely due to ctypes problems and a permissions issue with os.mkdir. If you run the test suite in XCode as a debug binary, the debugger will stop whenever a SIGPIPE, SIGINT, SIGXFSZ, SIGUSR1 or SIGUSR2 signal is raised. You can just hit continue in the debugger, and the test will continue. To work around this, you need to run the following debugger commands before the first signal is raised: process handle SIGPIPE -n true -p true -s false process handle SIGINT -n true -p true -s false process handle SIGXFSZ -n true -p true -s false process handle SIGUSR1 -n true -p true -s false process handle SIGUSR2 -n true -p true -s false I've been doing this by setting a breakpoint in the main.c method; I'm investigating other ways to automate this. -- Added file: http://bugs.python.org/file39286/20150504.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23670 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24124] Two versions of instructions for installing Python modules
New submission from Skip Montanaro: I was hunting around the current website for notes on installing Python. Couldn't find any (BTW), so I looked in the Python source. Imagine my surprise to find two apparently overlapping files describing how to build Python modules: ./Doc/install/index.rst ./Doc/installing/index.rst The former is marked Legacy version. The latter seems to cover mostly installation of third-party modules using tools like pip. The former covers distutils. Oddly enough, the legacy version seems to have been updated more recently than the presumably current version. Do we really need to keep both versions around at this point? Should they be merged into a single document? If they are to both be retained, should the legacy version be marked as such more clearly and refer readers to the pip/pyvenv/virtualenv version? -- assignee: docs@python components: Documentation messages: 242555 nosy: docs@python, skip.montanaro priority: normal severity: normal status: open title: Two versions of instructions for installing Python modules versions: Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24124 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23911] Move path-based bootstrap code to a separate frozen file.
Larry Hastings added the comment:
This checkin broke the buildbots. If you build trunk then run
./python -bb -m test test_site
the test fails. -bb is used by the normal test runner (make test).
The problem is in the lines
self.assertTrue(os.path.isabs(os__file__),
expected absolute path, got {}.format(os__file__))
self.assertTrue(os.path.isabs(os__cached__),
expected absolute path, got {}.format(os__cached__))
os__file__ and os__cached__ are bytes but you're passing them into .format() on
a str.

[issue24088] yield expression confusion
Jim Jewett added the comment: OK, then how about Current: When a generator function is called, it returns an iterator known as a generator. That generator then controls the execution of a generator function. The execution starts when one of the generator’s methods is called. Proposed: When a generator function is called, it does not complete its execution immediately. Instead, it keeps its execution frame intact, and returns a special kind of iterator known as a generator. The iteration starts when one of the generator’s methods is called, and the generator executes within the existing generator frame, rather than creating a new one. This still seems to suggest that the generator uses the same frame as the generator function that created it; I was not aware that this was a guarantee. (Reusing the same frame, yes.

[issue24000] More fixes for the Clinic mapping of converters to format units
Larry Hastings added the comment: I have no interest in naming str to pchar. Yes, *most* of the other converters are named after the C type they translate to. But so far converter names doesn't mention whether or not they represent pointers to types--it's object, not pobject, it's PyBytesObject, not pPyBytesObject. That suggests the name char for the converter. But we've already got a char, and it would be confusing to use that one converter for both chars (small ints / single characters) and strings. Adding p in front is not a convention we've ever used. The word pchar does not appear in the Python source tree. So the name pchar has no mnemonic value. If I were to follow your advice, I should prefer the name char_star. But now we're using nine letters for what is almost certainly the most common converter. And, again, the generic converter for objects is called object, I do not propose to rename it to object_star. So this converter's name would be an exception to the rule. But then again, C strings themselves are an exception to the rule. They're not a built-in type as much as they are a *convention*. So any name we give it will ultimately be something of a compromise. And as compromises go str is great. So far nobody has been confused by it. It's short, and universally, instantly clear as to its meaning. Furthermore, converters don't actually represent a C type. They represent a *mapping*, from a Python type (or types) to a single C type. So while it's a useful and productive convention to name converters after the type they convert to, it's hardly mandatory. And it would be a shame to squander clarity in service to a needless consistency. p.s. If we hold ourselves to this firm ideal, where every converter is named after its C type, what should we call the bool converter? What should we call the self converter? What should you call your proposed boolint converter? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24000 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

when does newlines get set in universal newlines mode?
Hi all,
I have a text file with Windows-style line terminators (\r\n) which I open in
universal newlines mode (Python 2.7). I would expect the newlines attribute to
be set after the first call to the readline() method, but apparently this is
not the case:
f=open('test_crlf', 'rU')
f.newlines
f.readline()
'foo\n'
f.newlines
f.readline()
'bar\n'
f.newlines
'\r\n'
On the other hand, the newlines attribute gets set after the first call to
readline() on a file with Unix-style line endings.
Is this a bug or a feature?
Thanks in advance,
Davide

Why do I get SyntaxError: invalid syntax
While copying pasting code to test, the following works:
from itertools import islice
from os import rename
from os.pathimport expanduser, split
from tempfile import NamedTemporaryFile
real_file = (expanduser('~/Twitter/testing.txt'))
(filepath,
file) = split(real_file)
with NamedTemporaryFile(mode = 'w', prefix = file + '_', dir = filepath,
delete = False) as tf:
tempfile = tf.name
with open(real_file, 'r') as f:
for line in islice(f, 1, None):
tf.write(line)
rename(tempfile, real_file)
But first I used:
from itertools import islice
from os import rename
from os.pathimport expanduser, split
from tempfile import NamedTemporaryFile
real_file = (expanduser('~/Twitter/testing.txt'))
(filepath,
file) = split(real_file)
with NamedTemporaryFile(mode = 'w', prefix = file + '_', dir = filepath,
delete = False) as tf:
tempfile = tf.name
with open(real_file, 'r') as f:
for line in islice(f, 1, None):
tf.write(line)
rename(tempfile, real_file)
But that gave:
File stdin, line 6

According to
https://docs.python.org/2.7/library/functions.html#open
If Python is built without universal newlines support a mode with 'U' is the
same as normal text mode. Note that file objects so opened also have an
attribute called newlines which has a value of None (if no newlines have yet
been seen), '\n', '\r', '\r\n', or a tuple containing all the newline types
seen.
I tried:
with open(tmp.txt, wb) as f: f.write(alpha\r\nbeta\rgamma\n)
...
f = open(tmp.txt, rU)
f.newlines
f.readline()
'alpha\n'
f.newlines
# expected: '\r\n'
f.readline()
'beta\n'
f.newlines
'\r\n' # expected: ('\r', '\r\n')
f.readline()
'gamma\n'
f.newlines
('\r', '\n', '\r\n')
I believe this is a bug.

I'm not sure it is, actually; imagine the text is coming in one
character at a time (eg from a pipe), and it's seen alpha\r. It
knows that this is a line, so it emits it; but until the next
character is read, it can't know whether it's going to be \r or \r\n.
What should it do? Read another character, which might block? Put \r
into .newlines, which might be wrong? Once it sees the \n, it knows
that it was \r\n (or rather, it assumes that files do not have lines
of text terminated by \r followed by blank lines terminated by \n -
because that would be stupid).
It may be worth documenting this limitation, but it's not something
that can easily be fixed without removing support for \r newlines -
although that might be an option, given that non-OSX Macs are
basically history now.

You have something that needs to build a C extension. To do that, you
need to have the Python headers installed. How did you install Python?
On Debian/Ubuntu family Linuxes, that's probably apt-get install
python3 - so getting the headers would be apt-get install
python3-dev. Give that a try, and then retry the pip install.

So if you do something like: def foo(a, b=[]): b.append(a) print(b) The b list will be the same list on each call and will retain all changes from previous calls. *super() doesn't do what you might expect in multiple inheritance situations, particularly if you're coming from Java where you never have to deal with multiple inheritance. It binds to the next class in the method resolution order, *not* necessarily the immediate superclass. This also means that the particular class bound to can vary depending on the specific class of the object. *[[None] * 8] * 8 doesn't create a 2-dimensional array of None. It creates one list containing None 8 times, and then it creates a second list containing the first list 8 times, *not* a list of 8 distinct lists. *If some_tuple is a tuple containing a list, then some_tuple[0] += ['foo'] will concatenate the list *but* will also raise a TypeError when it tries to reassign the list back to the tuple. -- https://mail.python.org/mailman/listinfo/python-list

You have something that needs to build a C extension. To do that,
you need to have the Python headers installed. How did you install
Python? On Debian/Ubuntu family Linuxes, that's probably apt-get
install python3 - so getting the headers would be apt-get install
python3-dev. Give that a try, and then retry the pip install.
I should have thought about that myself. :-(
An alternative is to switch to Windows and do away with this archaic
concept of users having to build code :)

[issue24000] More fixes for the Clinic mapping of converters to format units
Larry Hastings added the comment: As for why not length instead of zeroes: Because the primary reason for the parameter is specifying that the string can contain embedded zeroes. Returning the length is a side-effect of this, not the main point. If the string didn't have embedded zeroes, we wouldn't need the length. The only reason the code didn't have zeroes=True everywhere was because I screwed up and didn't realize all those mappings *should* have specified it. The documentation is very consistent about calling it a NUL. I don't think NUL=True or allow_NUL=true is particularly attractive; we never (almost never?) use capital letters in parameter names. So any other name is going to be a compromise. allow_null and allow_nul are misspellings, and don't convey the idea any better; they can confuse the reader with the related concept of NULL or None. At least zeroes has the benefit of being an actual word, representing a related concept.
