[issue22798] time.mktime doesn't update time.tzname
Akira Li added the comment: One of the ways to fix this issue is to synchronize time.tzname attribute with the corresponding C tzname variable. I've uploaded sync-time-timezone-attr-with-c.diff patch that synchronizes tzname, timezone, altzone, daylight attributes. The patch also includes tests. No docs changes are necessary. The code follows C, POSIX standards and the time module documentation. Any differences are unintetional. The patch also fixes wrong time.timezone issue http://bugs.python.org/issue22799 The patch doesn't use tm_gmtoff, tm_zone C values from jan, jul to set timezone, tzname time module attributes therefore it may break software that relies on that behaviour. I would be interested to hear about such instances. I've removed the cygwin branch in the code (I haven't found cygwin buildbot).

Amaury Forgeot d'Arc added the comment:
The patch looks good to me.
But it seems that the reverse operation is not possible in the general case:
.decode('unicode_escape') assumes a latin-1 or ascii encoding.
Should we document this?

[issue22939] integer overflow in iterator object
New submission from Clement Rouault:
I found an interger overflow in the standard iterator object
(Objects/iterobject.c)
The `it_index` attribute used by the iterator is a `Py_ssize_t` but overflow is
never checked. So after the index `PY_SSIZE_T_MAX`, the iterator object will
ask for the index `PY_SSIZE_T_MIN`.
Here is an example:
import sys
class Seq:
def __getitem__(self, item):
print([-] Asked for item at {0}.format(item))
return 0
s = Seq()
i = iter(s)
# Manually set `it_index` to PY_SSIZE_T_MAX without a loop
i.__setstate__(sys.maxsize)
next(i)
[-] Asked for item at 9223372036854775807
next(i)
[-] Asked for item at -9223372036854775808
I would be really interested in writing a patch but first I wanted to discuss
the expected behaviour and fix.
The iterator could stop after `PY_SSIZE_T_MAX` but it seems strange as other
iterator (like `enumobject`) handle values bigger than `PY_SSIZE_T_MAX`.
Or the same technique used in `enumobject` could be used: adding a field
`PyObject* en_longindex` (a python long) which would be used for values bigger
than `PY_SSIZE_T_MAX`

[issue19676] Add the namereplace error handler
Nick Coghlan added the comment: Patch looks good to me, too. As far as Amaury's question goes, isn't the general reverse operation the same as for the existing backslashreplace handler? That is, decode with the appropriate ASCII compatible encoding (since ASCII compatibility is needed for the escape sequences to be valid), then run the result through ast.literal_eval? (I'll grant we don't currently provide guidance on reversing backslashreplace either, but addressing that sounds like a separate question from this change) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19676 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22940] readline does not offer partial saves
New submission from bru: The readline module offers write_history_file from readline/history.h write_history, but there's no append_history_file that would invoke append_history from the C header. This causes inconveniences when saving history to a file (like shown there: https://docs.python.org/3.5/library/readline.html?highlight=readline#example). Indeed, say you have 2 interpreters (A) and (B) open. - (A) and (B) load the history, composed of (z) lines - you work on both, writing (a) lines in (A) and (b) lines in (b) - you close (A), the history file now has (z)+(a) - you close (B), the history file now has (z)+(b) Therefore (A) history (the (a) lines) is lost. Offering append_history_file would be a nice way to fix this problem: having (z)+(a)+(b) in the end would be easy. This is exactly what the attached patch does. With it are tests, doc and an example. I've not updated Misc/NEWS yet though (no issue #). -- components: Library (Lib) files: 0001-Add-readline.append_history_file-function.patch keywords: patch messages: 231661 nosy: bru priority: normal severity: normal status: open title: readline does not offer partial saves type: enhancement versions: Python 3.5 Added file: http://bugs.python.org/file37275/0001-Add-readline.append_history_file-function.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22940 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22941] IPv4Interface arithmetic changes subnet mask
New submission from Søren Løvborg:
Addition and subtraction of integers are documented for ipaddress.IPv4Address
and ipaddress.IPv6Address, but also work for IPv4Interface and IPv6Interface
(though the only documentation of this is a brief mention that the Interface
classes inherit from the respective Address classes). That's good.
The problem is that adding/subtracting an integer to an Interface object
changes the subnet mask (to max_prefixlen), something which is 1) not
documented and 2) not the least surprising result.
import ipaddress
ipaddress.IPv4Interface('10.0.0.1/8') + 1
IPv4Interface('10.0.0.2/32')
ipaddress.IPv6Interface('fd00::1/64') + 1
IPv6Interface('fd00::2/128')
Changing this breaks backwards compatibility; though since the ipaddress module
was provisional until recently and the behavior is undocumented, I hope it's
not too late to change.

Ben Hoyt added the comment: Akira, note the Using slower ctypes version of scandir -- this is the older, ctypes implementation of scandir. On Linux, depending on file system etc, that can often be slower. You need to at least be using the fast C version in _scandir.c, which is then half C, half Python.

[issue22945] Ctypes inconsistent between Linux and OS X
New submission from Daniel Standage: The ctypes documentation describes the '._as_parameter_' attribute, which simplifies using Python objects to encapsulate C objects. If a ctypes object with the '._as_parameter_' attribute defined is passed as a parameter to a C function, the value of '._as_parameter_' is supplied to the C function instead of a pointer to the Python project. At least that's how it's advertised to work. And it does indeed work as advertised on Linux, but on Mac OS X the mechanism doesn't appear to work correctly. I have created a small dummy example demonstrating this at https://github.com/standage/ctypes-demo. -- components: ctypes hgrepos: 281 messages: 231692 nosy: Daniel.Standage priority: normal severity: normal status: open title: Ctypes inconsistent between Linux and OS X type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22945 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
