It seems a little hokey to me, but the test passed on Linux and Solaris, hopefully other platforms too. ........ r55002 | georg.brandl | 2007-04-27 12:20:00 -0700 (Fri, 27 Apr 2007) | 2 lines Version fix (bug #1708710) ........ r55021 | neal.norwitz | 2007-04-29 16:53:24 -0700 (Sun, 29 Apr 2007) | 1 line There really are some tests that are problematic. ........ r55024 | kristjan.jonsson | 2007-04-30 08:17:46 -0700 (Mon, 30 Apr 2007) | 1 line Complete revamp of PCBuild8 directory. Use subdirectories for each project under the main pcbuild solution. Now make extensive use of property sheets to simplify project configuration. x64 build fully supported, and the process for building PGO version (Profiler Guided Optimization) simplified. All projects are now present, except _ssl, which needs to be reimplemented. Also, some of the projects that require external libraries need extra work to fully compile on x64. ........ r55025 | thomas.heller | 2007-04-30 08:44:17 -0700 (Mon, 30 Apr 2007) | 4 lines Make sure to call PyErr_NoMemory() in several places where PyMem_Malloc() could potentially fail.

The ValueError message now contains the correct pointer address. Will backport to release25-maint. ........ r55036 | georg.brandl | 2007-04-30 23:04:11 -0700 (Mon, 30 Apr 2007) | 2 lines Bug #1710295: exceptions are now new-style classes. ........ r55038 | georg.brandl | 2007-04-30 23:08:15 -0700 (Mon, 30 Apr 2007) | 2 lines Patch #1710352: add missing public functions to locale.__all__. ........ r55041 | vinay.sajip | 2007-05-01 03:20:03 -0700 (Tue, 01 May 2007) | 1 line Added new optional credentials argument to SMTPHandler.__init__, and smtp.login() is now called in SMTPHandler.emit() if credentials are specified. ........ r55042 | vinay.sajip | 2007-05-01 03:21:45 -0700 (Tue, 01 May 2007) | 1 line Added documentation for new optional credentials argument to SMTPHandler.__init__(). ........ r55070 | neal.norwitz | 2007-05-01 21:47:55 -0700 (Tue, 01 May 2007) | 3 lines Stop using PyMem_FREE while the GIL is not held.

This should be backported ........ r55090 | neal.norwitz | 2007-05-03 00:20:57 -0700 (Thu, 03 May 2007) | 4 lines Remove dead code. This code couldn't be reached because earlier in the function there is another check for z != Py_None. ........ r55092 | thomas.heller | 2007-05-03 05:02:08 -0700 (Thu, 03 May 2007) | 1 line Fix building _ctypes.pyd for x64 / Windows. ........ r55093 | thomas.heller | 2007-05-03 05:05:20 -0700 (Thu, 03 May 2007) | 1 line Don't truncate pointers to integers (on win64 platform). ........ r55094 | walter.doerwald | 2007-05-03 08:13:55 -0700 (Thu, 03 May 2007) | 3 lines Clarify the behaviour of PyUnicode_DecodeUTF16(): A BOM is only skipped in native order mode, and only if it's the first two bytes. ........ r55101 | kristjan.jonsson | 2007-05-03 13:04:53 -0700 (Thu, 03 May 2007) | 2 lines Fix pcbuild8 after recent overhaul: Added the version resource to python26.dll. Adjust stacksize to 2Mb and made large address aware for 32 bits, and set stacksize to 3Mb for 64 bits. Todo: Set .dll optimized load addresses, and side-by-side packaging of the python26.dll. ........ r55102 | kristjan.jonsson | 2007-05-03 13:09:56 -0700 (Thu, 03 May 2007) | 1 line Fix those parts in the testsuite that assumed that sys.maxint would cause overflow on x64. Now the testsuite is well behaved on that platform. ........ r55103 | kristjan.jonsson | 2007-05-03 13:27:03 -0700 (Thu, 03 May 2007) | 11 lines Fix problems in x64 build that were discovered by the testsuite: - Reenable modules on x64 that had been disabled aeons ago for Itanium. - Cleared up confusion about compilers for 64 bit windows. There is only Itanium and x64. Added macros MS_WINI64 and MS_WINX64 for those rare cases where it matters, such as the disabling of modules above. - Set target platform (_WIN32_WINNT and WINVER) to 0x0501 (XP) for x64, and 0x0400 (NT 4.0) otherwise, which are the targeted minimum platforms. - Fixed thread_nt.h. The emulated InterlockedCompareExchange function didn?\194?\180t work on x64, probaby due to the lack of a "volatile" specifier. Anyway, win95 is no longer a target platform. - Itertools module used wrong constant to check for overflow in count() - PyInt_AsSsize_t couldn't deal with attribute error when accessing the __long__ member. - PyLong_FromSsize_t() incorrectly specified that the operand were unsigned. With these changes, the x64 passes the testsuite, for those modules present. ........ r55107 | kristjan.jonsson | 2007-05-03 17:25:08 -0700 (Thu, 03 May 2007) | 1 line Revert compiler comment to AMD64 for x64/AMD64 builds. ........ r55115 | thomas.heller | 2007-05-04 00:14:39 -0700 (Fri, 04 May 2007) | 4 lines Fix some ctypes test crashes, when running with a debug Python version on win64 by using proper argtypes and restype function attributes. ........ r55117 | thomas.heller | 2007-05-04 01:20:41 -0700 (Fri, 04 May 2007) | 4 lines On 64-bit Windows, ffi_arg must be 8 bytes long. This fixes the remaining crashes in the ctypes tests, when functions return float or double types. ........ r55120 | kristjan.jonsson | 2007-05-04 08:48:15 -0700 (Fri, 04 May 2007) | 1 line Update the pcbuild8 solution. Straightened out the _ctypes project by using a .vsproj file and a masm64.rules file to avoid redundancy ........ r55121 | kristjan.jonsson | 2007-05-04 10:28:06 -0700 (Fri, 04 May 2007) | 1 line Minor fix of PCBuild8/_ctypes vcproj, moving include dir into the .vsprops file. ........ r55129 | thomas.heller | 2007-05-04 12:54:22 -0700 (Fri, 04 May 2007) | 3 lines Do not truncate 64-bit pointers to 32-bit integers.

The nb_long method of classobject now falls back to nb_int if there is no __long__ attribute present. ........ r55197 | collin.winter | 2007-05-08 21:14:36 -0700 (Tue, 08 May 2007) | 9 lines Fix a bug in test.test_support.open_urlresource(). If the call to requires() doesn't precede the filesystem check, we get the following situation: 1. ./python Lib/test/regrtest.py test_foo # test needs urlfetch, not enabled, so skipped 2. ./python Lib/test/regrtest.py -u urlfetch test_foo # test runs 3. ./python Lib/test/regrtest.py test_foo # test runs (!) By moving the call to requires() *before* the filesystem check, the fact that fetched files are cached on the local disk becomes an implementation detail, rather than a semantics-changing point of note. ........ r55198 | neal.norwitz | 2007-05-08 23:43:15 -0700 (Tue, 08 May 2007) | 1 line Add markup for True/False.

This should help reduce the false positives. The message about references leaking is maintained to provide as much info as possible rather than simply suppressing the message at the source. ........ r55242 | neal.norwitz | 2007-05-10 23:23:01 -0700 (Thu, 10 May 2007) | 1 line Fix typo in docstring (the module is popen2, not 3). ........ r55244 | neal.norwitz | 2007-05-10 23:56:52 -0700 (Thu, 10 May 2007) | 1 line Remove trailing whitespace in docstring ........ r55245 | neal.norwitz | 2007-05-10 23:57:33 -0700 (Thu, 10 May 2007) | 1 line Deprecate os.popen* and popen2 module in favor of the subprocess module. ........ r55247 | neal.norwitz | 2007-05-11 00:13:30 -0700 (Fri, 11 May 2007) | 1 line Deprecate os.popen* and popen2 module in favor of the subprocess module.

/* ---------------------------------------------------------------------------
Some time zone algebra. For a datetime x, let
x.n = x stripped of its timezone -- its naive time.
x.o = x.utcoffset(), and assuming that doesn't raise an exception or
return None
x.d = x.dst(), and assuming that doesn't raise an exception or
return None
x.s = x's standard offset, x.o - x.d
Now some derived rules, where k is a duration (timedelta).
1. x.o = x.s + x.d
This follows from the definition of x.s.
2. If x and y have the same tzinfo member, x.s = y.s.
This is actually a requirement, an assumption we need to make about
sane tzinfo classes.
3. The naive UTC time corresponding to x is x.n - x.o.
This is again a requirement for a sane tzinfo class.
4. (x+k).s = x.s
This follows from #2, and that datimetimetz+timedelta preserves tzinfo.
5. (x+k).n = x.n + k
Again follows from how arithmetic is defined.
Now we can explain tz.fromutc(x). Let's assume it's an interesting case
(meaning that the various tzinfo methods exist, and don't blow up or return
None when called).
The function wants to return a datetime y with timezone tz, equivalent to x.
x is already in UTC.
By #3, we want
y.n - y.o = x.n [1]
The algorithm starts by attaching tz to x.n, and calling that y. So
x.n = y.n at the start. Then it wants to add a duration k to y, so that [1]
becomes true; in effect, we want to solve [2] for k:
(y+k).n - (y+k).o = x.n [2]
By #1, this is the same as
(y+k).n - ((y+k).s + (y+k).d) = x.n [3]
By #5, (y+k).n = y.n + k, which equals x.n + k because x.n=y.n at the start.
Substituting that into [3],
x.n + k - (y+k).s - (y+k).d = x.n; the x.n terms cancel, leaving
k - (y+k).s - (y+k).d = 0; rearranging,
k = (y+k).s - (y+k).d; by #4, (y+k).s == y.s, so
k = y.s - (y+k).d
On the RHS, (y+k).d can't be computed directly, but y.s can be, and we
approximate k by ignoring the (y+k).d term at first. Note that k can't be
very large, since all offset-returning methods return a duration of magnitude
less than 24 hours. For that reason, if y is firmly in std time, (y+k).d must
be 0, so ignoring it has no consequence then.
In any case, the new value is
z = y + y.s [4]
It's helpful to step back at look at [4] from a higher level: it's simply
mapping from UTC to tz's standard time.
At this point, if
z.n - z.o = x.n [5]
we have an equivalent time, and are almost done. The insecurity here is
at the start of daylight time. Picture US Eastern for concreteness. The wall
time jumps from 1:59 to 3:00, and wall hours of the form 2:MM don't make good
sense then. The docs ask that an Eastern tzinfo class consider such a time to
be EDT (because it's "after 2"), which is a redundant spelling of 1:MM EST
on the day DST starts. We want to return the 1:MM EST spelling because that's
the only spelling that makes sense on the local wall clock.
In fact, if [5] holds at this point, we do have the standard-time spelling,
but that takes a bit of proof. We first prove a stronger result. What's the
difference between the LHS and RHS of [5]? Let
diff = x.n - (z.n - z.o) [6]
Now
z.n = by [4]
(y + y.s).n = by #5
y.n + y.s = since y.n = x.n
x.n + y.s = since z and y are have the same tzinfo member,
y.s = z.s by #2
x.n + z.s
Plugging that back into [6] gives
diff =
x.n - ((x.n + z.s) - z.o) = expanding
x.n - x.n - z.s + z.o = cancelling
- z.s + z.o = by #2
z.d
So diff = z.d.
If [5] is true now, diff = 0, so z.d = 0 too, and we have the standard-time
spelling we wanted in the endcase described above. We're done. Contrarily,
if z.d = 0, then we have a UTC equivalent, and are also done.
If [5] is not true now, diff = z.d != 0, and z.d is the offset we need to
add to z (in effect, z is in tz's standard time, and we need to shift the
local clock into tz's daylight time).
Let
z' = z + z.d = z + diff [7]
and we can again ask whether
z'.n - z'.o = x.n [8]
If so, we're done. If not, the tzinfo class is insane, according to the
assumptions we've made. This also requires a bit of proof. As before, let's
compute the difference between the LHS and RHS of [8] (and skipping some of
the justifications for the kinds of substitutions we've done several times
already):
diff' = x.n - (z'.n - z'.o) = replacing z'.n via [7]
x.n - (z.n + diff - z'.o) = replacing diff via [6]
x.n - (z.n + x.n - (z.n - z.o) - z'.o) =
x.n - z.n - x.n + z.n - z.o + z'.o = cancel x.n
- z.n + z.n - z.o + z'.o = cancel z.n
- z.o + z'.o = #1 twice
-z.s - z.d + z'.s + z'.d = z and z' have same tzinfo
z'.d - z.d
So z' is UTC-equivalent to x iff z'.d = z.d at this point. If they are equal,
we've found the UTC-equivalent so are done. In fact, we stop with [7] and
return z', not bothering to compute z'.d.
How could z.d and z'd differ? z' = z + z.d [7], so merely moving z' by
a dst() offset, and starting *from* a time already in DST (we know z.d != 0),
would have to change the result dst() returns: we start in DST, and moving
a little further into it takes us out of DST.
There isn't a sane case where this can happen. The closest it gets is at
the end of DST, where there's an hour in UTC with no spelling in a hybrid
tzinfo class. In US Eastern, that's 5:MM UTC = 0:MM EST = 1:MM EDT. During
that hour, on an Eastern clock 1:MM is taken as being in standard time (6:MM
UTC) because the docs insist on that, but 0:MM is taken as being in daylight
time (4:MM UTC). There is no local time mapping to 5:MM UTC. The local
clock jumps from 1:59 back to 1:00 again, and repeats the 1:MM hour in
standard time. Since that's what the local clock *does*, we want to map both
UTC hours 5:MM and 6:MM to 1:MM Eastern. The result is ambiguous
in local time, but so it goes -- it's the way the local clock works.
When x = 5:MM UTC is the input to this algorithm, x.o=0, y.o=-5 and y.d=0,
so z=0:MM. z.d=60 (minutes) then, so [5] doesn't hold and we keep going.
z' = z + z.d = 1:MM then, and z'.d=0, and z'.d - z.d = -60 != 0 so [8]
(correctly) concludes that z' is not UTC-equivalent to x.
Because we know z.d said z was in daylight time (else [5] would have held and
we would have stopped then), and we know z.d != z'.d (else [8] would have held
and we would have stopped then), and there are only 2 possible values dst() can
return in Eastern, it follows that z'.d must be 0 (which it is in the example,
but the reasoning doesn't depend on the example -- it depends on there being
two possible dst() outcomes, one zero and the other non-zero). Therefore
z' must be in standard time, and is the spelling we want in this case.
Note again that z' is not UTC-equivalent as far as the hybrid tzinfo class is
concerned (because it takes z' as being in standard time rather than the
daylight time we intend here), but returning it gives the real-life "local
clock repeats an hour" behavior when mapping the "unspellable" UTC hour into
tz.
When the input is 6:MM, z=1:MM and z.d=0, and we stop at once, again with
the 1:MM standard time spelling we want.
So how can this break? One of the assumptions must be violated. Two
possibilities:
1) [2] effectively says that y.s is invariant across all y belong to a given
time zone. This isn't true if, for political reasons or continental drift,
a region decides to change its base offset from UTC.
2) There may be versions of "double daylight" time where the tail end of
the analysis gives up a step too early. I haven't thought about that
enough to say.
In any case, it's clear that the default fromutc() is strong enough to handle
"almost all" time zones: so long as the standard offset is invariant, it
doesn't matter if daylight time transition points change from year to year, or
if daylight time is skipped in some years; it doesn't matter how large or
small dst() may get within its bounds; and it doesn't even matter if some
perverse time zone returns a negative dst()). So a breaking case must be
pretty bizarre, and a tzinfo subclass can override fromutc() if it is.
