I have code doing exactly this, and sometimes it's important to comment it as such (although I'll usually word it as pass on no args or something, rather than just pass nothing). But yes.

Thanks, but I don't understand your point yet. Could you give me another example in which something is passed? The point being made is that no values are is “passed” in a function call. If you have learned that term from elsewhere, it doesn't apply sensibly to Python. Hmmm. I don't know that I like that. I think that these two sentences mean the same thing: Call the function with x as argument. Pass x to the function. They both describe what is being done, only from slightly different points of view. You're free to think that, but I'm agreeing with Terry that the conflation is unwarranted and confusing in the attempt to explain what is happening. Rather, “Call the function ‘foo’ with ‘x’ as an argument” has no implication that the argument ‘x’ travels anywhere, or is exclusively located either inside the function or out of it, or any other inferences that are invited by the statement “Pass ‘x’ to the function”. So you may *intend* them to mean the same thing. But the terminology comes with baggage, both from other programming languages and from non-programming meanings of the English word “pass”. They don't communicate the same thing. In mathematics, to call a function is a completely abstract action. Right, and the terms aren't located anywhere we need to identify, they don't travel anywhere, and “pass” isn't used to refer to them. These are good reasons for avoiding the statement “pass a value ‘x’ to the function ‘foo’”. But in programming languages, calling a function has concrete actions: certain things have to happen even before the function itself executes. What sort of things? Well, for starters, somehow the arguments need to be passed to the function No. The function needs to *know what the arguments are*. Using the verb “pass” to refer to an action which has nothing to do with motion through any space is clearly confusing the matter here. If you say nothing is being passed, then my response would be Oh, you aren't calling the function at all? Or just calling it with no arguments? To which my response is “You're mistakenly conflating the above two statements”.

I acknowledge that “pass the value 1 to the function ‘foo’” is entrenched and I'm not advocating to remove it, but it's foolish to ignore that this term invites unwarranted inferences. Heck, you have argued strongly that the whole “how are values passed in Python?” question is rather misguided and can only be answered by casting out assumptions about “pass”. I'm saying the mis-guidance comes from using the verb “pass a value” for an action that doesn't involve values going anywhere. -- \ “It is the integrity of each individual human that is in final | `\examination.

My sys.excepthook dies painfully
I have some code which sets up a logger instance, then installs it as
sys.excepthook to capture any uncaught exceptions:
import logging
import logging.handlers
import sys
FACILITY = logging.handlers.SysLogHandler.LOG_LOCAL6
mylogger = logging.getLogger('spam')
handler = logging.handlers.SysLogHandler(
address='/dev/log', facility=FACILITY)
formatter = logging.Formatter(%(levelname)s:%(message)s [%(module)s])
handler.setFormatter(formatter)
mylogger.addHandler(handler)
mylogger.setLevel(logging.DEBUG)
mylogger.info('started logging')
def my_error_handler(type, value, tb):
msg = Uncaught %s: %s % (type, value)
mylogger.exception(msg)
sys.__excepthook__(type, value, tb) # print the traceback to stderr
# Install exception handler.
mylogger.info('installing error handler')
sys.excepthook = my_error_handler
foo # Die with uncaught NameError.
If I run this code, the INFO logging messages are logged, but the
exception is not. Instead it is printed to the console:
Error in sys.excepthook:
Traceback (most recent call last):
File /home/steve/mylogging.py, line 28, in my_error_handler
mylogger.exception(msg)
AttributeError: 'NoneType' object has no attribute 'exception'
Original exception was:
Traceback (most recent call last):
[...]
File /home/steve/mylogging.py, line 35, in module
foo
NameError: name 'foo' is not defined
(I've trimmed out some of the traceback, because the details aren't
relevant.)
Any ideas what I'm doing wrong? How does mylogger get set to None?

From what I can see, the problem is that sys.exc_info() is returning None, None, None at this point, and the Logger.exception() method specifically looks for the currently-being-handled exception. You can get equivalent functionality with this: def my_error_handler(type, value, tb): msg = Uncaught %s: %s % (type, value) mylogger.error(msg, exc_info=(type, value, tb)) sys.__excepthook__(type, value, tb) # print the traceback to stderr At least, I think that's correct. It does seem to dump a lot of stuff into a single line in the log, though. Can't repro your exact traceback, though, so I don't know what's going on there.

This, by the way, depends on a feature of the zip file format: you start reading from the back, with the key indexes, and then come to the front. It's designed to allow various self-extracting archive formats to be easily unzipped (imagine, if you will, a SFX built for Windows when you're on Unix - rather than try to run the program (with all the difficulties and risks that would entail), you just unzip it), and it works nicely here too. I suppose, then, it would be possible to make a minimal Unix SFX prefix: #!/usr/bin/env unzip\n on the beginning of a zip should do the job :) (Yes, I'm aware that that violates most of the point of an SFX, in that the target system doesn't need to have pkunzip installed, but it's still neat how short it can be.)

Easier way: Don't have a master desktop app, but instead have a master database. Since you're posting this to python-list, I'll assume you currently intend writing this in Python; you can make a really simple transition from single-user-single-desktop to a networked system, although of course you'll want to think in terms of multiple users from the start. So... if everybody is using the same application to access the same database, how would you prevent say, a data entry user from accidentally breaking something above their pay-grade? Set up some sort of role-based privilege system to limit them to write access for some portions and read-only for others? That would be one way, yes. The first question you'd need to ask is: How do you know who's data-entry and who's admins? As soon as you solve that (probably with some sort of login), you tie the access level to that. Given the small user base and the nature of the events, volunteer staff, everybody knowing everybody, etc. its pretty much a matter of the match admin saying You, you and you - data entry ;) If you need absolute security, you would have the user enter a login and password which would actually be the database credentials. Then you grant exact rights in the database manager, permitting ONLY what that user is allowed to do. It's then utterly impossible, even for someone who knows Python and SQL, to do damage. Intriguing... and probably the most technically correct way as far as role-based access. But also very unlikely that most of the end-users would be able to set up the DB correctly. Just sayin'... But more likely, what you really want is a cut-down UI that simplifies things: if the user is data-entry level, you take away all the admin-type options. It might be possible to fiddle around in internals and gain elevated access, but that's not an issue in many environments. That sounds very much like what I'm thinking of... maybe a token nod @ security with a passwd for 'admin' and 'data-entry' roles to keep idle passers-by from snooping or diddling with things they shouldn't. Even if it just greyed-out / disabled buttons, tabs, etc. based on role that would probably meet needs. In any case, these are issues you'd need to figure out regardless of the development model.

If you were to create a web application, you'd have to worry about the same question of is this person an admin or just data-entry. If you were to do this as a single program that other programs script, you'd have to worry about the same question. It's not complexity inherent in the model of database is king, and there are several applications; it's complexity inherent in the original problem we will have separate admins and data-entry people. Incidentally, there is another way you could lay it out: have two separate programs, one of which is the d-e and the other is admins. That could work out very nicely, if you have a specially cut-down and simplified UI for d-e. It'd be like how some accounting packages have a special Point-Of-Sale mode, which doesn't have permission to process anything other than straight-forward sales, and which will use the entire screen just for that. It's a useful feature even when you completely trust the people involved; the simpler UI can allow increased throughput.

Call that one the system Python, and treat it like bash, grep, and all those other important tools. You'll only mess up your system if you mess with that.

You'll probably need to make sure the path to it is the same as it was on the system that installed it, and you'll definitely want to do this only on systems with the same architecture, but otherwise you should be fine. Make yourself a /usr/central/bin/python or something, install Python into it, and then make /usr/central on all the others as a mount point for /usr/central on the one where you installed it.

Could you give me another example in which something is passed? The point being made is that no values are is “passed” in a function call. If you have learned that term from elsewhere, it doesn't apply sensibly to Python. Hmmm. I don't know that I like that. I think that these two sentences mean the same thing: Call the function with x as argument. Pass x to the function. I disagree. In Python, when one calls the function with an argument, computer implementatipns 'pass' an object reference, which in CPython is an object address. Conflating the two sentences above leads people to claim that python 'calls by (object) reference'. In a sense, it does, But thinking in those terms often leads to false inferences about how Python behaves. So I think it better not to think is such terms. They both describe what is being done, only from slightly different points of view. 'Passing' is an implementation of calling. I have little idea what *I* do when interpreting a function call while interpreting python code. In mathematics, to call a function is a completely abstract action. Magic happens, and a result is returned. From a set theory point of view, nothing happens. The result simply is the second member of the pair with the argument as the first member. But in programming languages, calling a function has concrete actions: The *essential* concrete action is the binding of something to parameter names. 'Passing' is a means to that end. What matters is what gets bound. In Python, python objects themselves get bound. And the binding is essentially the same as in assignment statements. Other language bind values or references or pointers or ..., with different consequences. -- Terry Jan Reedy -- https://mail.python.org/mailman/listinfo/python-list

In particular, I'd like to know if asyncio.sleep() is used as a
substitute for slow/time consuming operation, i.e. in real code,
whether there will be a real time consuming statement in place of
asyncio.sleep().
The context is
while True:
print('Hello')
yield from asyncio.sleep(3)
sleep is both itself, to shown to schedule something at intervals in a
non-blocking fashion, as well as a placefiller. The blocking equivalent
would use 'time' instead of 'yield from asyncio'. The following shows
the non-blocking feature a bit better.
import asyncio

def hello():
while True:
print('Hello')

In other words, the problem changed when you added the NameError

Would it be possible to snapshot all critical globals with a closure,
to force them to be held? Something like:
def handler_gen(mylogger, sys):
def my_error_handler(type, value, tb):
msg = Uncaught %s: %s % (type, value)
mylogger.exception(msg)
sys.__excepthook__(type, value, tb) # print the traceback to stderr
# Install exception handler.
mylogger.info('installing error handler')
sys.excepthook = handler_gen(mylogger, sys)
It seems crazy, but it might work. It's a guaranteed one-way
connection, saying this function NEEDS these objects.

If you have learned that term from elsewhere, it doesn't apply sensibly to Python. Hmmm. I don't know that I like that. I think that these two sentences mean the same thing: Call the function with x as argument. Pass x to the function. I disagree. In Python, when one calls the function with an argument, computer implementatipns 'pass' an object reference, Terry, while I appreciate that you are trying to prevent confusion, I think you're actually causing even more confusion than what you are arguing against. Starting with yourself. I stated that call function with argument x and pass x to function mean the same thing. You said that you disagree, and then the very next sentence you link the two concepts together: when you call a function with an argument, the computer passes something to the function in some manner. By your own description, one implies the other. If not, then I'd like to see an example of a programming language where you can have one without the other. I respectfully disagree with you and Ben Finney on this matter. I think that the plain English meanings of the two sentences will be understood as the same thing by any English speaker old enough to have learned about functions (in mathematics or computing), and that there is no harm in this any more than it is harmful to treat these as the same: I went for a stroll by the river. I took a leisurely walk along the river. which in CPython is an object address. If we're talking CPython implementation, then surely it passes a pointer, which is an abstract data type and not necessarily just an address. (Pointers in most languages that have them also have a type, not just a value.) But that's just a niggle. Conflating the two sentences above leads people to claim that python 'calls by (object) reference'. In a sense, it does, But thinking in those terms often leads to false inferences about how Python behaves. So I think it better not to think is such terms. I don't agree that this is the cause of the problem. As I've stated many times now, I believe that the problem is that people believe that there are only two argument passing conventions, pass by value and pass by reference. Do you think it helps matters one iota if we refer to them as call by value and call by reference instead of pass ...? I've never found anyone claiming that Python is call by name, even though the semantics of call by name are very similar to those of call by reference. I'd even argue that call by name is a *better* fit (still wrong, but not quite as wrong) as call by reference: the difference being that in call by reference semantics, the argument cannot be a literal, so we could not write this: some_function([]) but (as I understand it) with call by name semantics, you can. But because call by name is less well known than call by reference, people don't suggest it. By the way, you refer to call by object reference as being a wrong inference. I think your terminology is messed up, and if you want to argue I suggest you take it up with the Effbot: The most accurate description is CLU’s “call by object” or “call by sharing“. Or, if you prefer, “call by object reference“. http://effbot.org/zone/call-by-object.htm Call by object reference would be a good name for what Python does (since it actually is what CPython does), if not for the unfortunate fact that if you drop the word object it leaves call by reference, which of course is a different calling convention with well-defined, and very different, semantics. So I prefer call by object or call by sharing. But regardless of which name is used, we agree that that's what Python does (as well as Ruby and Java and others). This article: http://javadude.com/articles/passbyvalue.htm is a remarkable (and popular!) example of the confusion. Despite spending some time at the end of the article inventing his own terminology pass by memento and pass by proxy for remote method calls [and I'll get to them in a minute], the author spends the whole discussion implicitly assuming that call by value and call by reference are the only two ways that you can pass arguments to a function. This leads him to the remarkable conclusion that if you create a Dog instance and bind it a name myDog (in Java: Dog myDog; in Python, myDog = Dog()) the actual value of myDog is not the instance but some memory address, say 42. You have to be very clever to be that stupid. As Fredrik Lundh (the Effbot) wrote: well, I guess you can, in theory, value an artificial number assigned to an object as much as the object

There is a sense in which calling a function with argument x is slightly different from passing x to a function: when you call a function, the compiler has to do at least two things: 1) record enough information somewhere (usually on a call stack) so it can return back to the caller once the function returns; 2) record in some manner the arguments to the function where the function can get to them (pass the arguments). So if you want to be pedantic and argue that calling does more than passing arguments, I'll have to concede the point that you are technically correct. But in the context of discussing the treatment of arguments passed to the function when you call a function, I think that's a distinction that matters not. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

I'd like to learn the purpose of the statement
yield from asyncio.sleep(2) in that example.
In particular, I'd like to know if asyncio.sleep() is used as a
substitute for slow/time consuming operation, i.e. in real code,
whether there will be a real time consuming statement in place of
asyncio.sleep().
The context is
while True:
print('Hello')
yield from asyncio.sleep(3)
sleep is both itself, to shown to schedule something at intervals in a
non-blocking fashion, as well as a placefiller. The blocking equivalent
would use 'time' instead of 'yield from asyncio'. The following shows the
non-blocking feature a bit better.
import asyncio
@asyncio.coroutine
def hello():
while True:
print('Hello')
yield from asyncio.sleep(3)
@asyncio.coroutine
def goodbye():
while True:
print('Goodbye')

Getting the same time behavior in a while...sleep loop requires reproducing
some of the calculation and queue manipulation included in the event loop.

This tells you that mylogger is None.
This can happen during finalization. When the interpreter is shut down,
it unbinds all variables in a complex process (somewhere, there
is a description how it proceeds). Unbinding a variable effectively
means bindiung it to None.
This would suggest that the finalization starts before the excepthook

Lars Gustäbel added the comment: Apparently, the problem is located in TarInfo._proc_gnulong(). I attached a patch. When tarfile reads an archive, it strips trailing slashes from all filenames, except GNUTYPE_LONGNAME headers, which is a bug. tarfile creates GNU_FORMAT tar files by default, hence it uses an additional GNUTYPE_LONGNAME header for filenames 100 chars. That's why tarfile_issue.py fails if used with PAX_FORMAT, because PAX_FORMAT doesn't have this bug. -- keywords: +patch Added file: http://bugs.python.org/file36045/issue21987.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21987 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I think this set of changes really makes it clear how non-trivial it actually is to infer the binary domain behaviour from the str docs, which have all sorts of Unicode complications. You can't easily infer the behaviour from the Python 2 docs either, since these operations were locale dependent for Python 2 str objects. -- Added file: http://bugs.python.org/file36046/separate_binary_sequence_docs_v3.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21777 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22045] Python make issue
New submission from Shannon Kerr: If you execute the following commands on a system that doesn’t already have Python 2.7.X installed on it, it will result in bloated libs that statically link libpythyon2.7.a instead of the locally built libpython2.7.so: ./configure make sudo make install ./configure —enable-shared make sudo make install Due to the library search path order in the Python build tools being: -L /usr/local/lib -L . the first lib found is in /usr/local/lib and it is the static library, so this is used to link. This results in, for example, cPickle.so being 4.9M instead of 188K. Shouldn't the just-built local library be used before anything on the system? -- components: Build messages: 223736 nosy: skerr priority: normal severity: normal status: open title: Python make issue versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22045 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22046] ZipFile.read() should mention that it might throw NotImplementedError
New submission from Jason Heeris: As per issue 5701, the zipfile.ZipFile.read() method will throw a NotImplementedError if the compression scheme is not supported. However, there is no mention of this possibility in the documentation for the read() method. I would suggest, say, Calling read() on a ZipFile that uses an unsupported compression scheme (eg. implode) will raise a NotImplementedError. It looks like you can use the testzip() method to check that this won't happen (ie. after you open the file but before you extract an entry). If that is really the expected way to check for this kind of condition, it would be nice to mention that too (under either method). -- assignee: docs@python components: Documentation messages: 223737 nosy: detly, docs@python priority: normal severity: normal status: open title: ZipFile.read() should mention that it might throw NotImplementedError type: enhancement versions: Python 2.7, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22046 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue14484] missing return in win32_kill?
STINNER Victor added the comment: I understand that os.kill(pid, sig) should call TerminateProcess() or GenerateConsoleCtrlEvent() depending on the value of sig. The problem is that these two functions are very different. A process can set a control handler for CTRL_C_EVENT and CTRL_BREAK_EVENT, so can decide how to handle GenerateConsoleCtrlEvent() event. TerminateProcess() kills the process with the specified exit code. To me it looks wrong to call TerminateProcess() with a signal number or event for the exit code!? We need to expose TerminateProcess() as a new Python function, os.TerminateProcess(pid, exitcode) for example. os.kill(pid, sig) should raise a ValueError if sig is not CTRL_C_EVENT nor CTRL_BREAK_EVENT. -- nosy: +haypo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14484 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21423] concurrent.futures.ThreadPoolExecutor should accept an initializer argument
Dan O'Reilly added the comment: It seems like everyone agrees that this functionality is useful, so I'm reviving this in hopes of getting a patch pushed through. I've updated Andreas' patch so that it applies cleanly against the latest tree, and tweaked the handling of exceptions in initializer. Now, ProcessPoolExecutor will raise a BrokenPoolException should an initializer method fail, and ThreadPoolExecutor will raise a RunTimeError stating that the pool can't be used because an initializer failed. I was hoping to use multiprocessing.Pool's handling of initializer exceptions as a guide for the right behavior here, but it actually does terrible job: an exception raised in the initializer is completely unhandled, and results in an endless loop of new processes being started up and immediately failing. But that's a separate bug report. :) For now there are still unit tests for testing exceptions being raised in the initializer, but they're noisy; the traceback for each initializer exception gets printed to stdout. I'm not sure if that's undesirable behavior or not. If the new behavior looks ok, the docs will need an update to. -- nosy: +dan.oreilly Added file: http://bugs.python.org/file36047/pool_init.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21423 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

group2 = group1.add_mutually_exclusive_group()
group2.add_argument('-hello',action='store_true', help=A flag)

optional arguments:
-h, --help show this help message and exit
-hello A flag
skerr@gravel:~$
Note the double [[ around hello, but there is no double ]] to close it. This is
the error.
