"""Base class for compute drivers.
The interface to this class talks in terms of 'instances' (Amazon EC2 and
internal Nova terminology), by which we mean 'running virtual machine'
(XenAPI terminology) or domain (Xen or libvirt terminology).
An instance has an ID, which is the identifier chosen by Nova to represent
the instance further up the stack. This is unfortunately also called a
'name' elsewhere. As far as this layer is concerned, 'instance ID' and
'instance name' are synonyms.
Note that the instance ID or name is not human-readable or
customer-controlled -- it's an internal ID chosen by Nova. At the
nova.virt layer, instances do not have human-readable names at all -- such
things are only known higher up the stack.
Most virtualization platforms will also have their own identity schemes,
to uniquely identify a VM or domain. These IDs must stay internal to the
platform-specific layer, and never escape the connection interface. The
platform-specific layer is responsible for keeping track of which instance
ID maps to which platform-specific ID, and vice versa.
Some methods here take an instance of nova.compute.service.Instance. This
is the data structure used by nova.compute to store details regarding an
instance, and pass them into this layer. This layer is responsible for
translating that generic data structure into terms that are specific to the
virtualization platform.

"""This method is called when a security group is added to an instance.
This message is sent to the virtualization drivers on hosts that are
running an instance that belongs to a security group that has a rule
that references the security group identified by `security_group_id`.
It is the responsibility of this method to make sure any rules
that authorize traffic flow with members of the security group are
updated and any new members can communicate, and any removed members
cannot.
Scenario:
* we are running on host 'H0' and we have an instance 'i-0'.
* instance 'i-0' is a member of security group 'speaks-b'
* group 'speaks-b' has an ingress rule that authorizes group 'b'
* another host 'H1' runs an instance 'i-1'
* instance 'i-1' is a member of security group 'b'
When 'i-1' launches or terminates we will receive the message
to update members of group 'b', at which time we will make
any changes needed to the rules for instance 'i-0' to allow
or deny traffic coming from 'i-1', depending on if it is being
added or removed from the group.
In this scenario, 'i-1' could just as easily have been running on our
host 'H0' and this method would still have been called. The point was
that this method isn't called on the host where instances of that
group are running (as is the case with

are made to authorizing those instances.

module: win_msg
version_added: "2.3"
short_description: Sends a message to logged in users on Windows hosts.
description:
- Wraps the msg.exe command in order to send messages to Windows hosts.
options:
to:
description:
- Who to send the message to. Can be a username, sessionname or sessionid.
default: '*'
display_seconds:
description:
- How long to wait for receiver to acknowledge message, in seconds.
default: 10
wait:
description:
- Whether to wait for users to respond. Module will only wait for the number of seconds specified in display_seconds or 10 seconds if not specified.
However, if I(wait) is true, the message is sent to each logged on user in turn, waiting for the user to either press 'ok' or for
the timeout to elapse before moving on to the next user.
required: false
default: false
msg:
description:
- The text of the message to be displayed.
default: Hello world!
author: "Jon Hawkesworth (@jhawkesworth)"
notes:
- This module must run on a windows host, so ensure your play targets windows
hosts, or delegates to a windows host.

"""Quoted-printable content transfer encoding per RFCs 2045-2047.
This module handles the content transfer encoding method defined in RFC 2045
to encode US ASCII-like 8-bit data called `quoted-printable'. It is used to
safely encode text that is in a character set similar to the 7-bit US ASCII
character set, but that includes some 8-bit characters that are normally not
allowed in email bodies or headers.
Quoted-printable is very space-inefficient for encoding binary files; use the
email.base64MIME module for that instead.
This module provides an interface to encode and decode both headers and bodies
with quoted-printable encoding.
RFC 2045 defines a method for including character set information in an
`encoded-word' in a header. This method is commonly used for 8-bit real names
in To:/From:/Cc: etc. fields, as well as Subject: lines.
This module does not do the line wrapping or end-of-line character
conversion necessary for proper internationalized headers; it only
does dumb encoding and decoding. To deal with the various line
wrapping issues, use the email.Header module.

__op__, __rop__ = _operator_fallbacks(just_rational_op, operator.op)
In general, we want to implement the arithmetic operations so
that mixed-mode operations either call an implementation whose
author knew about the types of both arguments, or convert both
to the nearest built in type and do the operation there. In
Fraction, that means that we define __add__ and __radd__ as:
def __add__(self, other):
# Both types have numerators/denominator attributes,
# so do the operation directly
if isinstance(other, (int, Fraction)):
return Fraction(self.numerator * other.denominator +
other.numerator * self.denominator,
self.denominator * other.denominator)
# float and complex don't have those operations, but we
# know about those types, so special case them.
elif isinstance(other, float):
return float(self) + other
elif isinstance(other, complex):
return complex(self) + other
# Let the other type take over.
return NotImplemented
def __radd__(self, other):
# radd handles more types than add because there's
# nothing left to fall back to.
if isinstance(other, numbers.Rational):
return Fraction(self.numerator * other.denominator +
other.numerator * self.denominator,
self.denominator * other.denominator)
elif isinstance(other, Real):
return float(other) + float(self)
elif isinstance(other, Complex):
return complex(other) + complex(self)
return NotImplemented
There are 5 different cases for a mixed-type addition on
Fraction. I'll refer to all of the above code that doesn't
refer to Fraction, float, or complex as "boilerplate". 'r'
will be an instance of Fraction, which is a subtype of
Rational (r : Fraction <: Rational), and b : B <:
Complex. The first three involve 'r + b':
1. If B <: Fraction, int, float, or complex, we handle
that specially, and all is well.
2. If Fraction falls back to the boilerplate code, and it
were to return a value from __add__, we'd miss the
possibility that B defines a more intelligent __radd__,
so the boilerplate should return NotImplemented from
__add__. In particular, we don't handle Rational
here, even though we could get an exact answer, in case
the other type wants to do something special.
3. If B <: Fraction, Python tries B.__radd__ before
Fraction.__add__. This is ok, because it was
implemented with knowledge of Fraction, so it can
handle those instances before delegating to Real or
Complex.
The next two situations describe 'b + r'. We assume that b
didn't know about Fraction in its implementation, and that it
uses similar boilerplate code:
4. If B <: Rational, then __radd_ converts both to the
builtin rational type (hey look, that's us) and
proceeds.
5. Otherwise, __radd__ tries to find the nearest common
base ABC, and fall back to its builtin type. Since this
class doesn't subclass a concrete type, there's no
implementation to fall back to, so we need to try as
hard as possible to return an actual value, or the user
will get a TypeError.

class SequenceMatcher:
"""
SequenceMatcher is a flexible class for comparing pairs of sequences of
any type, so long as the sequence elements are hashable. The basic
algorithm predates, and is a little fancier than, an algorithm
published in the late 1980's by Ratcliff and Obershelp under the
hyperbolic name "gestalt pattern matching". The basic idea is to find
the longest contiguous matching subsequence that contains no "junk"
elements (R-O doesn't address junk). The same idea is then applied
recursively to the pieces of the sequences to the left and to the right
of the matching subsequence. This does not yield minimal edit
sequences, but does tend to yield matches that "look right" to people.
SequenceMatcher tries to compute a "human-friendly diff" between two
sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the
longest *contiguous* & junk-free matching subsequence. That's what
catches peoples' eyes. The Windows(tm) windiff has another interesting
notion, pairing up elements that appear uniquely in each sequence.
That, and the method here, appear to yield more intuitive difference
reports than does diff. This method appears to be the least vulnerable
to synching up on blocks of "junk lines", though (like blank lines in
ordinary text files, or maybe "<P>" lines in HTML files). That may be
because this is the only method of the 3 that has a *concept* of
"junk" <wink>.
Example, comparing two strings, and considering blanks to be "junk":
>>> s = SequenceMatcher(lambda x: x == " ",
... "private Thread currentThread;",
... "private volatile Thread currentThread;")
>>>
.ratio() returns a float in [0, 1], measuring the "similarity" of the
sequences. As a rule of thumb, a .ratio() value over 0.6 means the
sequences are close matches:
>>> print round(s.ratio(), 3)
... 0.866
>>>
If you're only interested in where the sequences match,
.get_matching_blocks() is handy:
>>> for block in s.get_matching_blocks():
>>> print "a[%d] and b[%d] match for %d elements" % block
a[0] and b[0] match for 8 elements
a[8] and b[17] match for 6 elements
a[14] and b[23] match for 15 elements
a[29] and b[38] match for 0 elements
>>>
Note that the last tuple returned by .get_matching_blocks() is always a
dummy, (len(a), len(b), 0), and this is the only case in which the last
tuple element (number of elements matched) is 0.
If you want to know how to change the first sequence into the second,
use .get_opcodes():
>>> for opcode in s.get_opcodes():
... print "%6s a[%d:%d] b[%d:%d]" % opcode
equal a[0:8] b[0:8]
insert a[8:8] b[8:17]
equal a[8:14] b[17:23]
equal a[14:29] b[23:38]
See the Differ class for a fancy human-friendly file differencer, which
uses SequenceMatcher both to compare sequences of lines, and to compare
sequences of characters within similar (near-matching) lines.
See also function get_close_matches() in this module, which shows how
simple code building on SequenceMatcher can be used to do useful work.
Timing: Basic R-O is cubic time worst case and quadratic time expected
case. SequenceMatcher is quadratic time for the worst case and has
expected-case behavior dependent in a complicated way on how many
elements the sequences have in common; best case time is linear.

happens to be adjacent to an "interesting" match.
Here's the same example as before, but considering blanks to be
junk. That prevents " abcd" from matching the " abcd" at the tail

class Differ:
r"""
Differ is a class for comparing sequences of lines of text, and
producing human-readable differences or deltas. Differ uses
SequenceMatcher both to compare sequences of lines, and to compare
sequences of characters within similar (near-matching) lines.
Each line of a Differ delta begins with a two-letter code::
'- ' line unique to sequence 1
'+ ' line unique to sequence 2
' ' line common to both sequences
'? ' line not present in either input sequence
Lines beginning with '? ' attempt to guide the eye to intraline
differences, and were not present in either input sequence. These lines
can be confusing if the sequences contain tab characters.
Note that Differ makes no claim to produce a *minimal* diff. To the
contrary, minimal diffs are often counter-intuitive, because they synch
up anywhere possible, sometimes accidental matches 100 pages apart.
Restricting synch points to contiguous matches preserves some notion of
locality, at the occasional cost of producing a longer diff.
Example: Comparing two texts.
First we set up the texts, sequences of individual single-line strings
ending with newlines (such sequences can also be obtained from the
`readlines()` method of file-like objects):
>>> text1 = ''' 1. Beautiful is better than ugly.
... 2. Explicit is better than implicit.
... 3. Simple is better than complex.
... 4. Complex is better than complicated.
... '''.splitlines(1)
>>> len(text1)
4
>>> text1[0][-1]
'\n'
>>> text2 = ''' 1. Beautiful is better than ugly.
... 3. Simple is better than complex.
... 4. Complicated is better than complex.
... 5. Flat is better than nested.
... '''.splitlines(1)
Next we instantiate a Differ object:
>>> d = Differ()
Note that when instantiating a Differ object we may pass functions to
filter out line and character 'junk'. See Differ.__init__ for details.
Finally, we compare the two:
>>> result = list(d.compare(text1, text2))
'result' is a list of strings, so let's pretty-print it:
>>> from pprint import pprint as _pprint
>>> _pprint(result)
[' 1. Beautiful is better than ugly.\n',
'- 2. Explicit is better than implicit.\n',
'- 3. Simple is better than complex.\n',
'+ 3. Simple is better than complex.\n',
'? ++\n',
'- 4. Complex is better than complicated.\n',
'? ^ ---- ^\n',
'+ 4. Complicated is better than complex.\n',
'? ++++ ^ ^\n',
'+ 5. Flat is better than nested.\n']
As a single multi-line string it looks like this:
>>> print ''.join(result),
1. Beautiful is better than ugly.
- 2. Explicit is better than implicit.
- 3. Simple is better than complex.
+ 3. Simple is better than complex.
? ++
- 4. Complex is better than complicated.
? ^ ---- ^
+ 4. Complicated is better than complex.
? ++++ ^ ^
+ 5. Flat is better than nested.

Compare `a` and `b` (lists of strings); return a `Differ`-style delta.
Optional keyword parameters `linejunk` and `charjunk` are for filter
functions (or None):
- linejunk: A function that should accept a single string argument, and
return true iff the string is junk. The default is module-level function
IS_LINE_JUNK, which filters out lines without visible characters, except
for at most one splat ('#').
- charjunk: A function that should accept a string of length 1. The
default is module-level function IS_CHARACTER_JUNK, which filters out
whitespace characters (a blank or tab; note: bad idea to include newline
in this!).
Tools/scripts/ndiff.py is a command-line front-end to this function.
Example:
>>> diff = ndiff('one\ntwo\nthree\n'.splitlines(1),
... 'ore\ntree\nemu\n'.splitlines(1))
>>> print ''.join(diff),
- one
? ^
+ ore
? ^
- two
- three
? -
+ tree
+ emu
"""

r"""
Generate one of the two sequences that generated a delta.
Given a `delta` produced by `Differ.compare()` or `ndiff()`, extract
lines originating from file 1 or 2 (parameter `which`), stripping off line
prefixes.
Examples:
>>> diff = ndiff('one\ntwo\nthree\n'.splitlines(1),
... 'ore\ntree\nemu\n'.splitlines(1))

zooba/PTVS | Python/Product/Miniconda/Miniconda3-x64/Lib/site-packages/setuptools/build_meta.py | 5 | 9387 | """A PEP 517 interface to setuptools
Previously, when a user or a command line tool (let's call it a "frontend")
needed to make a request of setuptools to take a certain action, for
example, generating a list of installation requirements, the frontend would
would call "setup.py egg_info" or "setup.py bdist_wheel" on the command line.
PEP 517 defines a different method of interfacing with setuptools. Rather
than calling "setup.py" directly, the frontend should:
1. Set the current directory to the directory with a setup.py file
2. Import this module into a safe python interpreter (one in which
setuptools can potentially set global variables or crash hard).
3. Call one of the functions defined in PEP 517.
What each function does is defined in PEP 517. However, here is a "casual"
definition of the functions (this definition should not be relied on for
bug reports or API stability):
- `build_wheel`: build a wheel in the folder and return the basename
- `get_requires_for_build_wheel`: get the `setup_requires` to build
- `prepare_metadata_for_build_wheel`: get the `install_requires`
- `build_sdist`: build an sdist in the folder and return the basename
- `get_requires_for_build_sdist`: get the `setup_requires` to build
Again, this is not a formal definition! Just a "taste" of the module.

Together with the CSS and JavaScript files of the debugger this gives

3 state HMM Notes
In each emission matrix, the emissions for A,C, and G should be the same.
It is the emissions for T, T1, and T2 that change.
In the unlabeled state, it is predominantly T.
In label 1 state, it is predominantly T with an increase of T1 up to ~10% of Ts.
In label 2 state, it is predominantly T with an increase of T2 up to ~10% of Ts.
---
The transitions from/to the 3 states:
In unlabeled state, self-to-self should be quite high and self-to-other should be equivalen to label1 or label2.
--> In big picture, one is equallly as likely to be 5' to label 1 state as to label2 state.
--> active origins ~200kb apart on average in yeast (although all origins are 35kb apart) [[Lengronne et al, NAR, 2001, "Monitoring S phase ..."]]
--> When randomly sampling in between active origins, on average you will be 100kb 5' to next active origin
--> However, the label from the fork from that origin is equally likely to be anywhere within that 100 kb
--> Thus, on average one is ~50kb away from label
--> So starting in the unlabeled state, the probability of seeing a labeled state is 1/50kb
--> i.e. prob of not seeing label and staying in unlabeled state is 49.999kb/50kb
--> self-to-self = 0.99998
--> self to either label = 0.00002
--> self to specific label = 0.00002/2 = 0.00001
In label 1 (or 2), self-to-self should be high (but not as high as unlabel-to-unlabel since these are shorter stretches)
--> prob of staying in label is proportional to mean length of stretch that is labeled (which is proportional to labeling time)
--> Assume 1000 bp labels
--> Then self-to-self = 999/500 = 0.999
--> And self-to-other = 0.001
--> And self-to-specific-other = 0.001/2 = 0.0005
---
The init:
--> over-estimating ~400 replication forks in the genome
---(means ~every other origin is used at 2 forks per origin (200 origins used))
--> assuming 100% of cells in S-phase
--> assuming 1000 bp labeled per label per fork * 2 labeling periods = 2000 bp labeled per fork
-- which is 4000 bp label per activated origin (2 forks)
--> 200 origins * 2 forks/origin * 2000 label/fork = 800,000; 100*0.8e6/12e6 = 6.667% of DNA would be labeled 3.337% per label)
--> assuming only 30% of cells in S-phase, then 0.3* 6.667 = 2% of DNA would have label (1% per label)
--> For development, I will just assume 1% of DNA for each label

## use profile to segment statepath into origins, terms, free-float type 1 (X->Y), free-float type2 (Y->X)
## define these as 4 profiles that all go back to background
## The 4 profiles share states, but these states can just be redundant
## e.g. origin profile can have Y->X->Y ..... I will think about tomorrow...
## perhaps can just compress each segment of statepath into single emissions
