[issue32500] PySequence_Length() raises TypeError on dict type

[Michał Górny]

New submission from Michał Górny :

While debugging PyPy test failure on backports.lzma [1], I've noticed that 
PySequence_Check() on a dict type raises TypeError, e.g.:

  Traceback (most recent call last):
File "test/test_lzma.py", line 273, in test_bad_args
  b"", format=lzma.FORMAT_RAW, filters={})
File 
"/home/mgorny/git/backports.lzma/build/lib.linux-x86_64-3.6/backports/lzma/__init__.py",
 line 463, in decompress
  decomp = LZMADecompressor(format, memlimit, filters)
  TypeError: object of type 'dict' has no len()

The relevant C code is:

  static int
  parse_filter_chain_spec(lzma_filter filters[], PyObject *filterspecs)
  {
Py_ssize_t i, num_filters;

num_filters = PySequence_Length(filterspecs);
...

where filterspecs is the object corresponding to the {} dict in Python snippet.

According to the documentation [2], PySequence_Length() should be 'equivalent 
to the Python expression len(o).' The Python expression obviously does not 
raise TypeError:

  >>> len({})
  0

Therefore, I think that the behavior of PySequence_Length() is a bug, and the 
function should successfully return the dict length instead.

Standard (“official”) terms are most likely to be had from the language
reference . I would recommend
the glossary , but with the
caveat that many flaws have been found in recent years.

The only term I take issue with there is “superclass”. In a
multiple-inheritance system, such as provided by Python, the superclass
is *not* necessarily the base class. See this article from 2011
.

> So, are base class & subclass the proper terms?

In my opinion you will be correct to use those terms. Which is not to
say that other terms aren't also good.

The “etc.” seems pretty important, there. You want the behaviour of
‘bytearray’ without actually inheriting that behaviour from the
‘bytearray’ type.

So, it seems your options are:

* Enumerate all the things, specifically, that you do want your new type
  to do. Don't hide anything in “etc.”, so that you know exactly what
  behaviours need to be implemented. Implement all those behaviours,
  without benefit of inheriting from ‘bytearray’.

* Inherit from ‘bytearray’, but ameliorate the problems you want to
  avoid. This will require enumerating all those problems, so that you
  can know whether you have avoided them. Don't hide any of them in an
  “etc.”.

Python Inheritance Terminology

[Irv Kalb]

I'm doing some writing for an upcoming course on OOP using Python.  

I have been doing OOP programming for many years in many different languages, 
and I want make sure that I'm using the appropriate terminology in Python.  I'd 
like to know if there are "official" or even standard terms that are used to 
describe a class that is inherited from, and the class that is doing the 
inheriting.  From my reading (especially the PSF docs.python.org 
), it looks like the terms would be "base class" and 
"subclass".

However, in books about Python and other languages, I have also seen the terms:

base class & derived class
parent class & child class
superclass & subclass

So, are base class & subclass the proper terms?

Thanks,

Irv

Native object exposing buffer protocol

[Rob Gaddi]

I'd like to create a native Python object that exposes the buffer 
protocol.  Basically, something with a ._data member which is a 
bytearray that I can still readinto, make directly into a numpy array, etc.


I can do it by inheriting the entire thing from bytearray directly, but 
that gives me a whole lot of methods that are unsuitable for what I'm 
doing with it, which is reading the contents of a binary file, allowing 
them to be lightly malleable in memory, and then sending them on to a 
device.


Not the end of the world (the file's less than 2KB), but it seems like 
something that should be doable easily without having to throw around a 
lot of extraneous copies.

[Martin Panter]

Martin Panter  added the comment:

Thanks, although the fact that “Content-Length: 0” doesn’t work kills my theory 
about the proxy.

The “close_connection” flag is also a documented public API of Python: 
.
 According to the rules for framing the message body in 
, the presence of 
“Connection: close” is not important. The server actually shutting down the 
connection is the key. That is why I prefer to explicitly set the flag (if it 
works).

Anyway, your current proposal makes the server send a valid full HTTP response.

[issue32486] tail optimization for 'yield from'

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I think this should have been first floated on python-ideas list.  One 
objection is the same as for eliminating tail calls in general: it collapses 
tracebacks.

def g1():
yield from g2()
def g2():
yield 1/0
for i in g1(): pass

Traceback (most recent call last):
  File "F:\Python\a\tem.py", line 7, in 
for i in g1(): pass
  File "F:\Python\a\tem.py", line 2, in g1
yield from g2()
  File "F:\Python\a\tem.py", line 5, in g2
yield 1/0
ZeroDivisionError: division by zero

There was at least some discussion of making 'yield from' internally more 
efficient without actual replacement.  I don't know what the current CPython 
implementation does.

It's true that compared to ten years ago, the quantity of posts here
has diminished by a significant fraction, maybe even by an order of
magnitude. This is still a great place for discussion however, as long
as that discussion is about Python.

If this post is (as it appears to be) just a backhanded way of
complaining that not many are responding to your excessive and
trollish posts, then try making higher-quality posts that are actually
on topic.

Absolutely. You have absolutely no right to make demands of any of the

Look I can publish non-working garbage if I want. Who are you to say

Please, no!  We don't need emoji in this group. Fortunately the vast

have to worry about that kind of nonsense.

Anyway, it sounds like the software you are trying to get running is

I have tried value 0 for "Content-Length" (along with "text/plain" for 
"Content-Type"), it was when I said I tried both "Content-Length" and 
"Content-Type", while I haven't tried directly setting "close_connection" in 
the handler, my solution is based on how "send_error()" works internally, not 
only that, but send_header is public API (by convention) and the "Connection" 
header is part of HTTP 1.1 so it should be documented ( reference: 
https://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html ), so I don't really 
understand why my initial solution is consider "undocumented logic"

If you read the traceback the message is "correct" for some definition of 
correct: the right hand side controls the type of the expression, so it is

There are probably ways this could be improved, but I'm not sure it is worth

Sorry William, I forgot the client was waiting to read. But I don’t understand

something similar at work recently.)

You said “my suggestion will never work”, but did you try setting 
“close_connection” on its own:

def do_GET(self):
self.send_response(HTTPStatus.OK)
self.end_headers()
self.close_connection = True  # Terminate response body to proxy

You tried adding Content-Length, but did you try “Content-Length: 0”:

I seriously doubt you had the same opinion when you were 7 y.o.
I meant school as "junior/middle/high school/university/college"
school, because you still have to wake up early in the morning and go
to school.

So yes, life sucks most of the time anyway...

Thank you.

[issue32450] non-descriptive variable name

[Terry J. Reedy]

Terry J. Reedy  added the comment:

'ndots' is an internal name in the import-from branch of the import statement 
handler.  It seems reasonable in that context.  'level' is part of the public 
api for the ImportFrom node class, and cannot be changed as such.  It is also 
the parameter that receives the ndot value in the ImportFrom call, to be 
assigned to the level attribute.  Making the name switch in the call is at 
least as reasonable as in the assignment.  I am not the expert here, but I 
would be inclined to rejected this as not worth the code churn.

[issue32448] subscriptable

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I agree that a better message would be nice.  But compiling 'a.b[c]' breaks the 
expression apart into the equivalent of 't=a.b; t[c]', where 't' is an 
anonymous reference, so as David notes, there is no 'name' left to display.  We 
don't have a 'not possible resoluton, so "won't fix (because not possible)" 
seems closest.

Moreover, most of the time life sucks.
Every morning you have to go to school/work instead of staying home

And you are lucky if the school/work is in the same city where you family is...

I dunno about yours. Mine does. It's the default XFCE terminal on

it supports everything else.

The AIX buildbots has been exhibiting testsuite failures, but not build 
(compile) failures. The buildbots do not visibly distinguish between the two 
cases in a strong manner.

We can disable / expect failure for the few, additional testcases on AIX so 
that the buildbots will report "success" to make new failures more obvious.

[issue32497] datetime.strptime creates tz naive object from value containing a tzname

[Paul Ganssle]

Paul Ganssle  added the comment:

By the way, one possibly significant problem with this interface is that it 
would tend to encourage the use of static timezone offsets rather than rule 
sets as intended by `tzinfo`. The main problem is that a simple mapping between 
tzname and tzinfo (whether done with a Mapping or a callable) will actually 
lose information about the fold that is encoded in the chosen tzname.

In dateutil, I solved this problem by attaching the timezone object and 
checking whether the `.tzname()` of the created datetime matches the string it 
was parsed from, and if not, set fold=1 and check again - if that one matches, 
use fold=1, otherwise just return it with fold=0. This is obviously a heuristic 
metric that will not always work.

Two possible more general solutions to this problem:

1. have a variant of `strptime` that returns a `datetime` and the contents of 
`%Z` and let users or third party libraries handle converting the string into a 
timezone and attaching it to the datetime.
2. have `tzinfos` take a callable like `handle_tzinfo(dt, tzstr)` which returns 
the localized datetime.
3. have separate `tzinfos` and `apply_tzinfo` arguments, the first generating 
the `tzinfo` object, the second of the format `apply_tzinfo(dt, tz)` - if the 
second one doesn't exist, the default implementation is just `lambda dt, tz: 
dt.replace(tzinfo=tz)` (or equivalent)

#1 is a pretty significant (and possibly awkward) change to the interface, and 
#2 makes the implementation of these mappings less convenient for the 
downstream users, but is probably the most elegant from an API perspective. #3 
is a somewhat reasonable marriage of #1 and #2, but it's ugly and I'm fairly 
certain it would lead to a lot of buggy code out there from people who don't 
realize why you would need to implement the apply function.

The compilation error occurs only on the master branch, issue 32143 is the 
enhancement that is the  initial cause of this problem. This went unnoticed 
when issue 32143 was resolved because the AIX buildbots were already failing at 
that time for another reason.

[issue32497] datetime.strptime creates tz naive object from value containing a tzname

[Paul Ganssle]

Paul Ganssle  added the comment:

This is essentially what the `tzinfos` argument to `dateutil.parser.parse` 
does. I do think something *like* this is the only reasonable way to handle 
%Z->tzinfo mappings.

In `dateutil` 
(https://dateutil.readthedocs.io/en/latest/parser.html#dateutil.parser.parse), 
you can either pass a mapping or callable. Most of the problems we have in 
dateutil relate to the fact that we're both inferring what should or should not 
be interpreted as a time zone *and* passing it to the mapping or callable. 
Given that the first problem is solved by the format specifier already having 
an option for %Z, the implementation of this would be much easier.

I think the options for how this could be implemented are:

1. Mapping only
2. Callable only
3. Mapping or callable

Callable-only will probably lead to plenty of problems, since there's *already* 
a problem in this bug report, which is that `pytz.timezone` evidently doesn't 
do what Arjan thinks it does, because that function only *happens* to work. It 
would not work with, say, `CST` or `PST`. That said, callable is the most 
versatile way to do it, and if we don't include it, then people will probably 
end up having to work around it by creating mappings whose `.get` calls 
arbitrary functions.

#1 is probably the least convenient and #3 is the most convenient. Either way, 
I'd say that the primary documented interface should be mappings, since that's 
least error-prone (these mappings could be curated by third party libraries for 
a given local context). An advantage of using mappings is that if we ever have 
a C implementation of strptime, it can have a fast evalution path for when the 
mapping is a `Dict`.

Re: Re: Progress migrating cffi and pycparser to libclang

Hi Etienne,

> Forwarding  this thread to the CFFI developers...

If you're asking whether we could add libclang as a dependency to CFFI, the
answer is no, sorry.

I feel that I've already explained exactly this to you several times in
private e-mails, so I'm writing down this fact here on the public
python-cffi mailing list.  Please stop asking the same question.

For reference, here's my answer again.  CFFI is meant to be used in a
certain way.  I know from experience that a few people keep thinking about
it in a different way---sometimes for good reasons: it is tedious to wrap a
very large library even if it is easy to copy-paste-tweak individual
function definitions.  So to automate the process these people usually want
to parse real .h files, using libclang or better pycparser integration or
something else; and that's cool.  As I said there are already third-party
projects that try to do something similar.  Usually it is never completely
general, but more focused on a particular style of .h files coming from a
particular large project.  Maybe you'll run into similar issues and make
something that works in your case but not in others.  Or maybe you'll
manage to make it general enough.  In all cases this won't be included
inside CFFI, but could nevertheless be a successful separate project.
Please think about it as a project *above* CFFI, maybe something you'll
import and use inside a CFFI build script in order to provide content to
ffi.cdef().


A bientôt,

Armin.

[ANN] iPOPO 0.7.0

[Thomas Calmant]

Hello, 

I'm happy to announce that iPOPO v0.7.0 has just been released!


What is iPOPO
=

iPOPO is a Service-Oriented Component Model (SOCM) based on Pelix,
a dynamic service platform. Both are inspired on two popular Java
technologies for the development of long-lived applications:
the iPOJO component model and the OSGi Service Platform.
iPOPO enables to conceive long-running and modular IT services.

It is based on the concepts specified by OSGi:
  - Bundle: a Python module imported using Pelix and associated to a
  context. A bundle has a life-cycle (install, start, updated, stop,
  uninstall)
  - Service: a Python object registered in a service registry,
  associated to a specification and to properties.
  - Component: the instance of a class described/manipulated by iPOPO
  decorators

Components are bound together by the specification(s) of the service(s)
they provide. The required services are injected into components by iPOPO.

For more information about those concepts, see
https://ipopo.readthedocs.io/en/latest/refcards/index.html#refcards


iPOPO provides many services out-of-the-box, like an HTTP server,
local and remote shell, remote services...


iPOPO is released under the terms of Apache Software License 2.0


What's new in 0.7.0
===

This version mainly adds:
* Prototype Service Factories
* Automatic release of consumed services when a bundle stops.
This will avoid some stale references when using service
factories.
   
WARNING: This is an important change in behavior, which might
break some projects which use stale references to pass
information from one bundle version to another during an
update (which is a bad way to do it).

* Deprecation handling of the imp package
* Added a Framework.delete() method to avoid the need to know
  about the FrameworkFactory class.

This release also removes some Python 2.6 compatibility code that was
remaining and which is not necessary anymore, as this version of
Python is not supported anymore by iPOPO.

Due to the behavior change caused by the automatic release of
consumed services, this release is version 0.7.0 instead of 0.6.6,
as it could break some existing code.


What's coming in 2018
=

2018 will be the year when iPOPO will get its Web Console. It will be
developed as a separate project (in fact, the project already exists
but is staled).

This might also be the year when Remote Service Admin will be added
to iPOPO, thanks to Scott Lewis!
See https://github.com/tcalmant/ipopo/issues/60 for more information.


You can take a look at the documentation at https://ipopo.readthedocs.io/
iPOPO is available on PyPI: https://pypi.python.org/pypi/iPOPO
Source is available on GitHub: https://github.com/tcalmant/ipopo
Feel free to send feedback on your experience of Pelix/iPOPO, via the mailing 
lists:

User list : http://groups.google.com/group/ipopo-users

Have fun! and Happy New Year!

ANN: Pandas v0.22.0 released

[Tom Augspurger]

Hi all,

I'm happy to announce pandas 0.22.0 has been released.

This is a major release from 0.21.1 and includes a single, API-breaking
change. We recommend that all users upgrade to this version after carefully
reading the release note.

The only changes are:

   - The sum of an empty or all-*NA* Series is now 0
   - The product of an empty or all-*NA* Series is now 1
   - We’ve added a min_count parameter to .sum() and .prod() controlling
   the minimum number of valid values for the result to be valid. If fewer
   than min_count non-*NA* values are present, the result is *NA*. The
   default is 0. To return NaN, the 0.21 behavior, use min_count=1.

See the pandas 0.22.0 whatsnew

overview for further explanation of all the places in the library this
affects.

- Tom

---

committment to just 8 pages – 4 pages front and back. It turns out there is a 
physics problem involved here – you just can’t stuff 10 pounds of poop in a 5 
pound sack. 
So version JR2 has expanded to 10 pages and now includes a small number of 
corrections – but a massively reformated attributes table with the additon of a 
notes column, a completely reformated methods table, almost 2 pages of 
operational commands that were missing completely, lots more vetted examples, 
almost a page on adding tkk, plus several more helpful filler items. If you 
think that sounds like a LOT more than just 2 additional pages, well, just take 
a look. As always, no registration, no fees, no charges, no cookies, no email 
list, no contribution accepted and no ads (for now). Toolboxes download from 
GitHub - for safety and larger file sizes. Comments and suggestions 
appreciated; I prefer email at oakey.j...@yahoo.com.

[Giampaolo Rodola']

Hello all,
I'm glad to announce the release of psutil 5.4.3:
https://github.com/giampaolo/psutil

About
=

psutil (process and system utilities) is a cross-platform library for
retrieving information on running processes and system utilization (CPU,
memory, disks, network) in Python. It is useful mainly for system
monitoring, profiling and limiting process resources and management of
running processes. It implements many functionalities offered by command
line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free,
nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It
currently supports Linux, Windows, OSX, Sun Solaris, FreeBSD, OpenBSD,
NetBSD and AIX, both 32-bit and 64-bit architectures, with Python versions
from 2.6 to 3.6. PyPy is also known to work.

Michael, does AIX have uint32_t?  If so, we could happily drop the unsigned32

[issue32441] os.dup2 should return the new fd

[Xavier de Gaye]

Xavier de Gaye  added the comment:

gcc is a little bit lost and prints now the following (false) warning:

gcc -pthread -Wno-unused-result -Wsign-compare -g -Og -Wall -Wstrict-prototypes 
   -std=c99 -Wextra
-Wno-unused-result -Wno-unused-parameter -Wno-missing-field-initializers

function ‘os_dup2_impl’:
./Modules/posixmodule.c:7785:9: warning: ‘res’ may be used uninitialized in 
this function [-Wmaybe-uninitialized]
 int res;
 ^~~


The following change fools gcc that does not print anymore the warning:

diff --git a/Modules/posixmodule.c b/Modules/posixmodule.c
index 47b79fcc79..90d73daf97 100644
--- a/Modules/posixmodule.c

@@ -7845,7 +7845,7 @@ os_dup2_impl(PyObject *module, int fd, int fd2, int 
inheritable)
 }
 }
 
-if (inheritable || dup3_works == 0)
+if (inheritable || (!inheritable && dup3_works == 0))
 {
 #endif
 Py_BEGIN_ALLOW_THREADS


The change does not modify the behavior:
* dup3_works == 0 is equivalent to ((inheritable && dup3_works == 0) || 
(!inheritable && dup3_works == 0))
* (inheritable && dup3_works == 0) is always false
* hence dup3_works == 0 is equivalent to (!inheritable && dup3_works == 0)

[issue32497] datetime.strptime creates tz naive object from value containing a tzname

[Arjan Keeman]

New submission from Arjan Keeman :

Consider the following:

tz_naive_object = datetime.strptime("2018-01-05 13:10:00 CET", "%Y-%m-%d 
%H:%M:%S %Z")

Python's standard library is not capable of converting the timezone name CET to 
a tzinfo object. Therefore the case made above returns a timezone naive 
datetime object.

I propose to add an extra optional argument to _strptime.py's 
_strptime_datetime function, and to datetime.strptime: 
tzname_to_tzinfo:Optional[Callable[[str],Optional[tzinfo]]]=None. This 
parameter can be set with a function that accepts the timezone name and returns 
a tzinfo object or None (like pytz.timezone). None will mean that a timezone 
naive object will be created.

Usage:
tz_aware_object = datetime.strptime("2018-01-05 13:10:00 CET", "%Y-%m-%d 
%H:%M:%S %Z", pytz.timezone)

[issue25095] test_httpservers hangs since Python 3.5

[William Pickard]

William Pickard  added the comment:

Martin, your suggestion will never work as if you look at the trace back posted 
terry.reedy and my test print statements, both the client and server get stuck 
waiting to read data their respective socket, hence the deadlock. Adding the 
header "Connection" with value of "close" is logic taken from the method 
"send_error()" which is what test_err executes (same test class), that header 
along with send_error() adding the Content-Type and Content-Length headers, 
those headers are what is different between do_ERROR and do_GET, I've already 
tried locally having do_GET set both Content-Type and Content-Length headers 
without the Connection header, no difference (deadlock continued).

[issue25095] test_httpservers hangs since Python 3.5

[Martin Panter]

Martin Panter  added the comment:

In the server, the send_header("Connection", "close") call sets the 
“close_connection” flag. This shuts down the connection once “do_GET” returns. 
Without the flag set, the server will wait and read another request.

If you want the server to shut the connection down, I suggest to be explicit in 
setting “close_connection”. It should work even if no “Connection: close” 
appears in the HTTP protocol. The special behaviour of “send_header” I think 
you are relying on is not documented.

On my Linux computer with the original code, I think the client shuts the 
connection down. This causes the server to see an empty “raw_requestline” and 
return from “handle_one_request”. It returns to “serve_forever” where it polls 
the “__shutdown_request” flag and sees that it should stop.

The client shuts down the connection only because of subtleties in how the HTTP 
client manages the socket and how sockets are garbage collected. The response 
does not have Content-Length nor Transfer-Encoding fields, and would be 
terminated by the server shutting the connection down. So the HTTPConnection 
object cannot reuse the TCP connection and hands ownership to the HTTPResponse 
object returned by “getresponse”. Since this object is not saved anywhere, it 
gets garbage collected, which closes the socket and shuts the connection down. 
But perhaps on Windows the shutdown doesn’t happen, or perhaps the garbage 
collector is too slow.

If I am right, closing the HTTPResponse object would also fix the deadlock. It 
is good practice to close the underlying socket anyway:

with support.captured_stderr() as err:
self.con.request('GET', '/')
res = self.con.getresponse()

# Shut down connection to stop the server reading from it
res.close()
self.con.close()

sendline buffer

[Iranna Mathapati]

Hi Team,

I have faced fallowing issue::

 dev.sendline("*show version*")  <<< its printing "show version output"
 dev.sendline("*show module*")   <<< its printing "shoe module output"

*Runing again*

 dev.sendline("show veriosn")   <<< its runing 2nd time again

 dev.before  *output is not consistence means some time it printing
"shoe version output" or some time its printing only "show module output"*

can you please let me know , how to resolve the issue.


Thanks,

[issue17972] inspect module docs omits many functions

[Paul Rudin]

Paul Rudin  added the comment:

Documenting and generating a deprecation warning also makes them part of the 
documented public api. Or are you suggesting just the warning without including 
in the documentation?

Incidentally, there are also the classes BlockFinder and EndOfBlock, which are 
helpers for getblock and presumably not intended for public consumption.

[issue32457] Windows Python cannot handle an early PATH entry containing ".." and python.exe

[Eryk Sun]

Eryk Sun  added the comment:

For extra measure, you may want to normalize `prefix` prior to calculating its 
length n in gotlandmark(). Then it would be reliable to truncate it via 
`prefix[n] = '\0'` after joining with `landmark`. Or at least add a comment 
there or in the calling function, search_for_prefix(), that gotlandmark assumes 
the current value of `prefix` is a canonical, normalized path.

Fwd: Re: Progress migrating cffi and pycparser to libclang

Forwarding  this thread to the CFFI developers...

Re Paul: Thanks for your feedback.

My intended audience are developers who can use hg to fetch/build source 
code without pip.

As a fork/extension for cffi, I have no particular opinion (I'm
unlikely to ever use it). But the advantage of pycparser is that it's
cross-platform and pure Python, so I doubt this will be acceptable for
inclusion into CFFI itself.


CFFI/pycparser definitely need to be patched to support parsing standard C
directives like #define and #include in the ffi.cdef() function.

The easiest solution is to migrate the internal parsing code to libclang, a
state-of-the art C/C++ compiler based on LLVM.


I would strongly object to adding a dependency to cffi that couldn't
be automatically installed by pip as part of standard dependency
resolution (i.e., a PyPI hosted Python project with wheels available
for all common platforms - Linux, Mac OS and Windows). But ultimately
if you're proposing this as a change to cffi, you should be getting
the opinions of the cffi devs, not just asking on this list. (I notice
you have posted to the cffi mailing list, but haven't had any response
yet).

[issue32495] Adding Timer to multiprocessing

[Antoine Pitrou]

Antoine Pitrou  added the comment:

The threading.Timer class is in my experience little used, for two reasons:
1) it's not very flexible (no periodic calls, no restart...)
2) it's not efficient (as it creates a new thread for each timer)
3) (third optional reason) many applications needing time management actually 
use an event loop of some kind, as the need for time management is often 
coupled with the requirement to do network I/O

A hypothetical multiprocessing.Timer would have the same drawbacks as 
threading.Timer, the inefficiency being of course much worse.
