        GNU GENERAL PUBLIC LICENSE
 | 
			
		||||
           Version 2, June 1991
 | 
			
		||||
 | 
			
		||||
 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
 | 
			
		||||
 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
 | 
			
		||||
 Everyone is permitted to copy and distribute verbatim copies
 | 
			
		||||
 of this license document, but changing it is not allowed.
 | 
			
		||||
 | 
			
		||||
          Preamble
 | 
			
		||||
 | 
			
		||||
  The licenses for most software are designed to take away your
 | 
			
		||||
freedom to share and change it.  By contrast, the GNU General Public
 | 
			
		||||
License is intended to guarantee your freedom to share and change free
 | 
			
		||||
software--to make sure the software is free for all its users.  This
 | 
			
		||||
General Public License applies to most of the Free Software
 | 
			
		||||
Foundation's software and to any other program whose authors commit to
 | 
			
		||||
using it.  (Some other Free Software Foundation software is covered by
 | 
			
		||||
the GNU Lesser General Public License instead.)  You can apply it to
 | 
			
		||||
your programs, too.
 | 
			
		||||
 | 
			
		||||
  When we speak of free software, we are referring to freedom, not
 | 
			
		||||
price.  Our General Public Licenses are designed to make sure that you
 | 
			
		||||
have the freedom to distribute copies of free software (and charge for
 | 
			
		||||
this service if you wish), that you receive source code or can get it
 | 
			
		||||
if you want it, that you can change the software or use pieces of it
 | 
			
		||||
in new free programs; and that you know you can do these things.
 | 
			
		||||
 | 
			
		||||
  To protect your rights, we need to make restrictions that forbid
 | 
			
		||||
anyone to deny you these rights or to ask you to surrender the rights.
 | 
			
		||||
These restrictions translate to certain responsibilities for you if you
 | 
			
		||||
distribute copies of the software, or if you modify it.
 | 
			
		||||
 | 
			
		||||
  For example, if you distribute copies of such a program, whether
 | 
			
		||||
gratis or for a fee, you must give the recipients all the rights that
 | 
			
		||||
you have.  You must make sure that they, too, receive or can get the
 | 
			
		||||
source code.  And you must show them these terms so they know their
 | 
			
		||||
rights.
 | 
			
		||||
 | 
			
		||||
  We protect your rights with two steps: (1) copyright the software, and
 | 
			
		||||
(2) offer you this license which gives you legal permission to copy,
 | 
			
		||||
distribute and/or modify the software.
 | 
			
		||||
 | 
			
		||||
  Also, for each author's protection and ours, we want to make certain
 | 
			
		||||
that everyone understands that there is no warranty for this free
 | 
			
		||||
software.  If the software is modified by someone else and passed on, we
 | 
			
		||||
want its recipients to know that what they have is not the original, so
 | 
			
		||||
that any problems introduced by others will not reflect on the original
 | 
			
		||||
authors' reputations.
 | 
			
		||||
 | 
			
		||||
  Finally, any free program is threatened constantly by software
 | 
			
		||||
patents.  We wish to avoid the danger that redistributors of a free
 | 
			
		||||
program will individually obtain patent licenses, in effect making the
 | 
			
		||||
program proprietary.  To prevent this, we have made it clear that any
 | 
			
		||||
patent must be licensed for everyone's free use or not licensed at all.
 | 
			
		||||
 | 
			
		||||
  The precise terms and conditions for copying, distribution and
 | 
			
		||||
modification follow.
 | 
			
		||||
 | 
			
		||||
        GNU GENERAL PUBLIC LICENSE
 | 
			
		||||
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 | 
			
		||||
 | 
			
		||||
  0. This License applies to any program or other work which contains
 | 
			
		||||
a notice placed by the copyright holder saying it may be distributed
 | 
			
		||||
under the terms of this General Public License.  The "Program", below,
 | 
			
		||||
refers to any such program or work, and a "work based on the Program"
 | 
			
		||||
means either the Program or any derivative work under copyright law:
 | 
			
		||||
that is to say, a work containing the Program or a portion of it,
 | 
			
		||||
either verbatim or with modifications and/or translated into another
 | 
			
		||||
language.  (Hereinafter, translation is included without limitation in
 | 
			
		||||
the term "modification".)  Each licensee is addressed as "you".
 | 
			
		||||
 | 
			
		||||
Activities other than copying, distribution and modification are not
 | 
			
		||||
covered by this License; they are outside its scope.  The act of
 | 
			
		||||
running the Program is not restricted, and the output from the Program
 | 
			
		||||
is covered only if its contents constitute a work based on the
 | 
			
		||||
Program (independent of having been made by running the Program).
 | 
			
		||||
Whether that is true depends on what the Program does.
 | 
			
		||||
 | 
			
		||||
  1. You may copy and distribute verbatim copies of the Program's
 | 
			
		||||
source code as you receive it, in any medium, provided that you
 | 
			
		||||
conspicuously and appropriately publish on each copy an appropriate
 | 
			
		||||
copyright notice and disclaimer of warranty; keep intact all the
 | 
			
		||||
notices that refer to this License and to the absence of any warranty;
 | 
			
		||||
and give any other recipients of the Program a copy of this License
 | 
			
		||||
along with the Program.
 | 
			
		||||
 | 
			
		||||
You may charge a fee for the physical act of transferring a copy, and
 | 
			
		||||
you may at your option offer warranty protection in exchange for a fee.
 | 
			
		||||
 | 
			
		||||
  2. You may modify your copy or copies of the Program or any portion
 | 
			
		||||
of it, thus forming a work based on the Program, and copy and
 | 
			
		||||
distribute such modifications or work under the terms of Section 1
 | 
			
		||||
above, provided that you also meet all of these conditions:
 | 
			
		||||
 | 
			
		||||
    a) You must cause the modified files to carry prominent notices
 | 
			
		||||
    stating that you changed the files and the date of any change.
 | 
			
		||||
 | 
			
		||||
    b) You must cause any work that you distribute or publish, that in
 | 
			
		||||
    whole or in part contains or is derived from the Program or any
 | 
			
		||||
    part thereof, to be licensed as a whole at no charge to all third
 | 
			
		||||
    parties under the terms of this License.
 | 
			
		||||
 | 
			
		||||
    c) If the modified program normally reads commands interactively
 | 
			
		||||
    when run, you must cause it, when started running for such
 | 
			
		||||
    interactive use in the most ordinary way, to print or display an
 | 
			
		||||
    announcement including an appropriate copyright notice and a
 | 
			
		||||
    notice that there is no warranty (or else, saying that you provide
 | 
			
		||||
    a warranty) and that users may redistribute the program under
 | 
			
		||||
    these conditions, and telling the user how to view a copy of this
 | 
			
		||||
    License.  (Exception: if the Program itself is interactive but
 | 
			
		||||
    does not normally print such an announcement, your work based on
 | 
			
		||||
    the Program is not required to print an announcement.)
 | 
			
		||||
 | 
			
		||||
These requirements apply to the modified work as a whole.  If
 | 
			
		||||
identifiable sections of that work are not derived from the Program,
 | 
			
		||||
and can be reasonably considered independent and separate works in
 | 
			
		||||
themselves, then this License, and its terms, do not apply to those
 | 
			
		||||
sections when you distribute them as separate works.  But when you
 | 
			
		||||
distribute the same sections as part of a whole which is a work based
 | 
			
		||||
on the Program, the distribution of the whole must be on the terms of
 | 
			
		||||
this License, whose permissions for other licensees extend to the
 | 
			
		||||
entire whole, and thus to each and every part regardless of who wrote it.
 | 
			
		||||
 | 
			
		||||
Thus, it is not the intent of this section to claim rights or contest
 | 
			
		||||
your rights to work written entirely by you; rather, the intent is to
 | 
			
		||||
exercise the right to control the distribution of derivative or
 | 
			
		||||
collective works based on the Program.
 | 
			
		||||
 | 
			
		||||
In addition, mere aggregation of another work not based on the Program
 | 
			
		||||
with the Program (or with a work based on the Program) on a volume of
 | 
			
		||||
a storage or distribution medium does not bring the other work under
 | 
			
		||||
the scope of this License.
 | 
			
		||||
 | 
			
		||||
  3. You may copy and distribute the Program (or a work based on it,
 | 
			
		||||
under Section 2) in object code or executable form under the terms of
 | 
			
		||||
Sections 1 and 2 above provided that you also do one of the following:
 | 
			
		||||
 | 
			
		||||
    a) Accompany it with the complete corresponding machine-readable
 | 
			
		||||
    source code, which must be distributed under the terms of Sections
 | 
			
		||||
    1 and 2 above on a medium customarily used for software interchange; or,
 | 
			
		||||
 | 
			
		||||
    b) Accompany it with a written offer, valid for at least three
 | 
			
		||||
    years, to give any third party, for a charge no more than your
 | 
			
		||||
    cost of physically performing source distribution, a complete
 | 
			
		||||
    machine-readable copy of the corresponding source code, to be
 | 
			
		||||
    distributed under the terms of Sections 1 and 2 above on a medium
 | 
			
		||||
    customarily used for software interchange; or,
 | 
			
		||||
 | 
			
		||||
    c) Accompany it with the information you received as to the offer
 | 
			
		||||
    to distribute corresponding source code.  (This alternative is
 | 
			
		||||
    allowed only for noncommercial distribution and only if you
 | 
			
		||||
    received the program in object code or executable form with such
 | 
			
		||||
    an offer, in accord with Subsection b above.)
 | 
			
		||||
 | 
			
		||||
The source code for a work means the preferred form of the work for
 | 
			
		||||
making modifications to it.  For an executable work, complete source
 | 
			
		||||
code means all the source code for all modules it contains, plus any
 | 
			
		||||
associated interface definition files, plus the scripts used to
 | 
			
		||||
control compilation and installation of the executable.  However, as a
 | 
			
		||||
special exception, the source code distributed need not include
 | 
			
		||||
anything that is normally distributed (in either source or binary
 | 
			
		||||
form) with the major components (compiler, kernel, and so on) of the
 | 
			
		||||
operating system on which the executable runs, unless that component
 | 
			
		||||
itself accompanies the executable.
 | 
			
		||||
 | 
			
		||||
If distribution of executable or object code is made by offering
 | 
			
		||||
access to copy from a designated place, then offering equivalent
 | 
			
		||||
access to copy the source code from the same place counts as
 | 
			
		||||
distribution of the source code, even though third parties are not
 | 
			
		||||
compelled to copy the source along with the object code.
 | 
			
		||||
 | 
			
		||||
  4. You may not copy, modify, sublicense, or distribute the Program
 | 
			
		||||
except as expressly provided under this License.  Any attempt
 | 
			
		||||
otherwise to copy, modify, sublicense or distribute the Program is
 | 
			
		||||
void, and will automatically terminate your rights under this License.
 | 
			
		||||
However, parties who have received copies, or rights, from you under
 | 
			
		||||
this License will not have their licenses terminated so long as such
 | 
			
		||||
parties remain in full compliance.
 | 
			
		||||
 | 
			
		||||
  5. You are not required to accept this License, since you have not
 | 
			
		||||
signed it.  However, nothing else grants you permission to modify or
 | 
			
		||||
distribute the Program or its derivative works.  These actions are
 | 
			
		||||
prohibited by law if you do not accept this License.  Therefore, by
 | 
			
		||||
modifying or distributing the Program (or any work based on the
 | 
			
		||||
Program), you indicate your acceptance of this License to do so, and
 | 
			
		||||
all its terms and conditions for copying, distributing or modifying
 | 
			
		||||
the Program or works based on it.
 | 
			
		||||
 | 
			
		||||
  6. Each time you redistribute the Program (or any work based on the
 | 
			
		||||
Program), the recipient automatically receives a license from the
 | 
			
		||||
original licensor to copy, distribute or modify the Program subject to
 | 
			
		||||
these terms and conditions.  You may not impose any further
 | 
			
		||||
restrictions on the recipients' exercise of the rights granted herein.
 | 
			
		||||
You are not responsible for enforcing compliance by third parties to
 | 
			
		||||
this License.
 | 
			
		||||
 | 
			
		||||
  7. If, as a consequence of a court judgment or allegation of patent
 | 
			
		||||
infringement or for any other reason (not limited to patent issues),
 | 
			
		||||
conditions are imposed on you (whether by court order, agreement or
 | 
			
		||||
otherwise) that contradict the conditions of this License, they do not
 | 
			
		||||
excuse you from the conditions of this License.  If you cannot
 | 
			
		||||
distribute so as to satisfy simultaneously your obligations under this
 | 
			
		||||
License and any other pertinent obligations, then as a consequence you
 | 
			
		||||
may not distribute the Program at all.  For example, if a patent
 | 
			
		||||
license would not permit royalty-free redistribution of the Program by
 | 
			
		||||
all those who receive copies directly or indirectly through you, then
 | 
			
		||||
the only way you could satisfy both it and this License would be to
 | 
			
		||||
refrain entirely from distribution of the Program.
 | 
			
		||||
 | 
			
		||||
If any portion of this section is held invalid or unenforceable under
 | 
			
		||||
any particular circumstance, the balance of the section is intended to
 | 
			
		||||
apply and the section as a whole is intended to apply in other
 | 
			
		||||
circumstances.
 | 
			
		||||
 | 
			
		||||
It is not the purpose of this section to induce you to infringe any
 | 
			
		||||
patents or other property right claims or to contest validity of any
 | 
			
		||||
such claims; this section has the sole purpose of protecting the
 | 
			
		||||
integrity of the free software distribution system, which is
 | 
			
		||||
implemented by public license practices.  Many people have made
 | 
			
		||||
generous contributions to the wide range of software distributed
 | 
			
		||||
through that system in reliance on consistent application of that
 | 
			
		||||
system; it is up to the author/donor to decide if he or she is willing
 | 
			
		||||
to distribute software through any other system and a licensee cannot
 | 
			
		||||
impose that choice.
 | 
			
		||||
 | 
			
		||||
This section is intended to make thoroughly clear what is believed to
 | 
			
		||||
be a consequence of the rest of this License.
 | 
			
		||||
 | 
			
		||||
  8. If the distribution and/or use of the Program is restricted in
 | 
			
		||||
certain countries either by patents or by copyrighted interfaces, the
 | 
			
		||||
original copyright holder who places the Program under this License
 | 
			
		||||
may add an explicit geographical distribution limitation excluding
 | 
			
		||||
those countries, so that distribution is permitted only in or among
 | 
			
		||||
countries not thus excluded.  In such case, this License incorporates
 | 
			
		||||
the limitation as if written in the body of this License.
 | 
			
		||||
 | 
			
		||||
  9. The Free Software Foundation may publish revised and/or new versions
 | 
			
		||||
of the General Public License from time to time.  Such new versions will
 | 
			
		||||
be similar in spirit to the present version, but may differ in detail to
 | 
			
		||||
address new problems or concerns.
 | 
			
		||||
 | 
			
		||||
Each version is given a distinguishing version number.  If the Program
 | 
			
		||||
specifies a version number of this License which applies to it and "any
 | 
			
		||||
later version", you have the option of following the terms and conditions
 | 
			
		||||
either of that version or of any later version published by the Free
 | 
			
		||||
Software Foundation.  If the Program does not specify a version number of
 | 
			
		||||
this License, you may choose any version ever published by the Free Software
 | 
			
		||||
Foundation.
 | 
			
		||||
 | 
			
		||||
  10. If you wish to incorporate parts of the Program into other free
 | 
			
		||||
programs whose distribution conditions are different, write to the author
 | 
			
		||||
to ask for permission.  For software which is copyrighted by the Free
 | 
			
		||||
Software Foundation, write to the Free Software Foundation; we sometimes
 | 
			
		||||
make exceptions for this.  Our decision will be guided by the two goals
 | 
			
		||||
of preserving the free status of all derivatives of our free software and
 | 
			
		||||
of promoting the sharing and reuse of software generally.
 | 
			
		||||
 | 
			
		||||
          NO WARRANTY
 | 
			
		||||
 | 
			
		||||
  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 | 
			
		||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
 | 
			
		||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
 | 
			
		||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
 | 
			
		||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
 | 
			
		||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
 | 
			
		||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
 | 
			
		||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
 | 
			
		||||
REPAIR OR CORRECTION.
 | 
			
		||||
 | 
			
		||||
  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 | 
			
		||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 | 
			
		||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 | 
			
		||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
 | 
			
		||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
 | 
			
		||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
 | 
			
		||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
 | 
			
		||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
 | 
			
		||||
POSSIBILITY OF SUCH DAMAGES.
 | 
			
		||||
 | 
			
		||||
         END OF TERMS AND CONDITIONS
 | 
			
		||||
 | 
			
		||||
      How to Apply These Terms to Your New Programs
 | 
			
		||||
 | 
			
		||||
  If you develop a new program, and you want it to be of the greatest
 | 
			
		||||
possible use to the public, the best way to achieve this is to make it
 | 
			
		||||
free software which everyone can redistribute and change under these terms.
 | 
			
		||||
 | 
			
		||||
  To do so, attach the following notices to the program.  It is safest
 | 
			
		||||
to attach them to the start of each source file to most effectively
 | 
			
		||||
convey the exclusion of warranty; and each file should have at least
 | 
			
		||||
the "copyright" line and a pointer to where the full notice is found.
 | 
			
		||||
 | 
			
		||||
    <one line to give the program's name and a brief idea of what it does.>
 | 
			
		||||
    Copyright (C) <year>  <name of author>
 | 
			
		||||
 | 
			
		||||
    This program is free software; you can redistribute it and/or modify
 | 
			
		||||
    it under the terms of the GNU General Public License as published by
 | 
			
		||||
    the Free Software Foundation; either version 2 of the License, or
 | 
			
		||||
    (at your option) any later version.
 | 
			
		||||
 | 
			
		||||
    This program is distributed in the hope that it will be useful,
 | 
			
		||||
    but WITHOUT ANY WARRANTY; without even the implied warranty of
 | 
			
		||||
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 | 
			
		||||
    GNU General Public License for more details.
 | 
			
		||||
 | 
			
		||||
    You should have received a copy of the GNU General Public License along
 | 
			
		||||
    with this program; if not, write to the Free Software Foundation, Inc.,
 | 
			
		||||
    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
 | 
			
		||||
 | 
			
		||||
Also add information on how to contact you by electronic and paper mail.
 | 
			
		||||
 | 
			
		||||
If the program is interactive, make it output a short notice like this
 | 
			
		||||
when it starts in an interactive mode:
 | 
			
		||||

HOW-TO: Test this Drupal component
 | 
			
		||||
 | 
			
		||||
In order to test this component, you'll need to get the entire Drupal repo and
 | 
			
		||||
run the tests there.
 | 
			
		||||
 | 
			
		||||
You'll find the tests under core/tests/Drupal/Tests/Component.
 | 
			
		||||
 | 
			
		||||
You can get the full Drupal repo here:
 | 
			
		||||
https://www.drupal.org/project/drupal/git-instructions
 | 
			
		||||
 | 
			
		||||
You can find more information about running PHPUnit tests with Drupal here:
 | 
			
		||||
https://www.drupal.org/node/2116263
 | 
			
		||||
 | 
			
		||||
Each component in the Drupal\Component namespace has its own annotated test
 | 
			
		||||
group. You can use this group to run only the tests for this component. Like
 | 
			
		||||
this:
