In the current design, local time information is stored in the datetime object and the rules that govern UTC to local mapping (and back) are stored in the tzinfo object. The implementors of concrete tzinfo subclasses are supposed to have access to time zone rules and implement utcoffset(dt), together with dst(dt) and tzname(dt) methods. > > Storing isdst in the datetime object would allow utcoffset(dt) to distinguish between 1:30AM before clock change and 1:30AM after. Where do you propose to store the offset? I propose to add an offset field to datetime.datetime. It should be set precisely when the tz field is set, and it should contain either a timedelta or an integer number of (possibly fractional) seconds, depending on what color the bikeshed gets painted. This is, IIUC, precisely where Lennart is proposing to store the is_dst flag. I just looked through the datetime documentation, and it looks like the currently blessed way of creating an aware datetime from a naive local datetime and a tzinfo is datetime.replace, which is too low level to handle the job. This method will either need to grow some validation, or there will need to be a tzinfo.localize(localtime, is_dst) method as well. > If you store it in dt, why would you need the tzinfo? You can't do arithmetic without a time zone. Which is to say, if you try to do arithmetic without a time zone, you're implicitly doing it in a fixed offset time zone. So there's no way to disambiguate between "2013-11-03 01:30:00-0500 America/Chicago" + "1 hour" = "2013-11-03 01:30:00-0600 America/Chicago" and "2013-11-03 01:30:00-0500 America/New_York" + "1 hour" = "2013-11-03 02:30:00-0500 America/New_York". > > We really don't care whether a time is DST or not; > > You may not care about it, but current tzinfo interface and tzinfo.fromutc(dt) method do. Whatever new features are added to the standard library, they cannot break existing uses. This means that whatever concrete tzinfo implementations we add to stdlib, they must provide an implementation of tzinfo.dst(dt) method. I don't really mean we don't care; I mean that it's not close to orthogonal to the other things we care about in the way that local time and UTC time are. You'll never ask for *just* the DST flag. So making you look up in zoneinfo whether a given (localtime, offset, tzinfo) triple represents DST or STD is not as onerous, because if you used the other representation, you'd still be looking in zoneinfo for some other piece of information that the user asked for at the same time. So we implement the datetime.astimezone() > > So our times would look like "2013-11-03 01:30:00-0500 America/Chicago" and an hour later, "2013-11-03 01:30:00-0600 America/Chicago". And all of that information is stored in the datetime object. > > I don't think this is what most people would expect > > $ TZ=America/Chicago date > Wed Apr 8 18:26:01 CDT 2015 > > or > > $ TZ=America/Chicago date +"%c %z" > Wed 08 Apr 2015 06:27:09 PM CDT -0500 > > and not have location as a part of their timestamps. > Regardless, whatever the proposal to add timezones to stdlib will end up being, it must include the ability to implement an equivalent of UNIX date command shown above. Sorry, I meant that to show off the internal representation, rather than intending it as the literal string representation. But I *do* think that the right representation of a time zone-aware time is (localtime, offset, tzinfo), and the __repr__ should reflect that. Anyone who wants "CDT" instead of "-0500 America/Chicago" is talking to a human instead of a computer and should use strftime. ijs

I'm viewing a time zone as a map from UTC to local time; for example, America/Chicago is a time zone. I'm not proposing storing the offset as an alternative to storing the *time zone*, I'm proposing it as an alternative to storing whether a given time is DST or not. We really don't care whether a time is DST or not; we care about the local time and the offset, and we need the time zone because otherwise we can't relate our time to other times. So our times would look like "2013-11-03 01:30:00-0500 America/Chicago" and an hour later, "2013-11-03 01:30:00-0600 America/Chicago".

PEP 8 update
by Guido van Rossum 07 Apr '15

07 Apr '15

I've taken the liberty of adding the following old but good rule to PEP 8 (I was surprised to find it wasn't already there since I've lived by this for ages): - Be consistent in return statements. Either all return statements in a function should return an expression, or none of them should. If any return statement returns an expression, any return statements where no value is returned should explicitly state this as return None, and an explicit return statement should be present at the end of the function (if reachable). Yes: def foo(x): if x >= 0: return math.sqrt(x) else: return None def bar(x): if x < 0: return None return math.sqrt(x) No: def foo(x): if x >= 0: return math.sqrt(x) def bar(x): if x < 0: return return math.sqrt(x) -- --Guido van Rossum (python.org/~guido)

Build is broken for me after updating
by Neil Girdhar 07 Apr '15

Ever since I updated, I am getting: In file included from Objects/dictobject.c:236:0: Objects/clinic/dictobject.c.h:70:26: fatal error: stringlib/eq.h: No such file or directory #include "stringlib/eq.h" But, Objects/stringlib/eq.h exists. Replacing the include with "Objects/stringlib/eq.h" seems to make this error go away, but others follow. Would anyone happen to know why this is happening? Neil

Re: [Python-Dev] PEP 487 vs 422 (dynamic class decoration)

Just for the heck of it, here's an actual implementation and demo of PEP 487, that I've tested with 3.1, 3.2, and 3.4 (I didn't have a copy of 3.3 handy): https://gist.github.com/pjeby/75ca26f8d2a7a0c68e30 The first module is just a demo that shows the features in use. The second module is the implementation. Notice that the actual *functionality* of PEP 487 is just *16 lines* in Python 3... including docstrings and an `__all__` definition. ;-) The other 90 lines of code are only there to implement the `noconflict` feature for fixing metaclass conflicts... and quite a lot of *those* lines are comments and docstrings. ;-) Anyway, I think this demo is a knockout argument for why PEP 487 doesn't need a language change: if you're writing an __init_subclass__ method you just include the `pep487.init_subclasses` base in your base classes, and you're done. It'll silently fail if you leave it out (but you'll notice that right away), and it *won't* fail in third-party subclasses because the *third party* didn't include it. In contrast, PEP 422 provided a way to have both the features contemplated by 487, *and* a way to allow method-level decorators to discover the class at class creation time. If there's going to be a language change, it should include that latter feature from the outset.

Socket timeout: reset timeout at each successful syscall?
by Victor Stinner 04 Apr '15

04 Apr '15

Hi, I reworked the socket and ssl modules to better handle signals (to implement the PEP 475, retry on EINTR). These changes require to recompute timeout because syscalls are calling in a loop until it doesn't with EINTR (or EWOULDBLOCK or EGAIN). Most socket methods exit when the underlying syscall succeed. The problem is that the socket.sendall() method may require multiple syscalls. In this case, does the timeout count for the total time or only for a single syscall? Asked differently: should we reset the timeout each time a syscall succeed? Let's say that a server limits the bandwidth to 10 MB per second per client (or per connection). If I want to send 1000 MB, the request will take 100 seconds. Do you expect a timeout exception on calling call sendall() with a timeout of 60 seconds? Each call to send() may succeed in less than 60 seconds, for example each send() may send 1 MB in one second. In the socket documentation, I understand that the socket timeout is the total duration of an operation, not the maximum duration of a single syscall: https://docs.python.org/dev/library/socket.html#socket-timeouts "In timeout mode, operations fail if they cannot be completed within the timeout specified for the socket (they raise a timeout exception) or if the system returns an error." In Python 2.7, 3.4 and 3.5, socket.sendall() resets the timeout after each send() success. We had similar questions in the asyncio module, especially for StreamReader methods which can require multiple reads. I propose a patch to add a timeout parameter to StreamReader: it resets the timeout after each successful read. It's already possible to put a global timeout on any asyncio operationg. StreamReader timeout patch: https://bugs.python.org/issue23236 Note: there is also an open issue to add a socket.recvall() method which would open similar question on timeout: https://bugs.python.org/issue1103213 Victor

version of freshly built 2.7 python
by Ethan Furman 02 Apr '15

02 Apr '15

I just built the latest version of Python 2.7 on my development machine -- or so I thought. When I invoke it, I get: Python 2.7.6+ (2.7:1beb3e0507fa, Apr 2 2015, 17:57:53) Why am I not seeing 2.7.9? -- ~Ethan~
