GNU GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The GNU General Public License is a free, copyleft license for
|
||||
software and other kinds of works.
|
||||
|
||||
The licenses for most software and other practical works are designed
|
||||
to take away your freedom to share and change the works. By contrast,
|
||||
the GNU General Public License is intended to guarantee your freedom to
|
||||
share and change all versions of a program--to make sure it remains free
|
||||
software for all its users. We, the Free Software Foundation, use the
|
||||
GNU General Public License for most of our software; it applies also to
|
||||
any other work released this way by its authors. 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
|
||||
them 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 prevent others from denying you
|
||||
these rights or asking you to surrender the rights. Therefore, you have
|
||||
certain responsibilities if you distribute copies of the software, or if
|
||||
you modify it: responsibilities to respect the freedom of others.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must pass on to the recipients the same
|
||||
freedoms that you received. 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.
|
||||
|
||||
Developers that use the GNU GPL protect your rights with two steps:
|
||||
(1) assert copyright on the software, and (2) offer you this License
|
||||
giving you legal permission to copy, distribute and/or modify it.
|
||||
|
||||
For the developers' and authors' protection, the GPL clearly explains
|
||||
that there is no warranty for this free software. For both users' and
|
||||
authors' sake, the GPL requires that modified versions be marked as
|
||||
changed, so that their problems will not be attributed erroneously to
|
||||
authors of previous versions.
|
||||
|
||||
Some devices are designed to deny users access to install or run
|
||||
modified versions of the software inside them, although the manufacturer
|
||||
can do so. This is fundamentally incompatible with the aim of
|
||||
protecting users' freedom to change the software. The systematic
|
||||
pattern of such abuse occurs in the area of products for individuals to
|
||||
use, which is precisely where it is most unacceptable. Therefore, we
|
||||
have designed this version of the GPL to prohibit the practice for those
|
||||
products. If such problems arise substantially in other domains, we
|
||||
stand ready to extend this provision to those domains in future versions
|
||||
of the GPL, as needed to protect the freedom of users.
|
||||
|
||||
Finally, every program is threatened constantly by software patents.
|
||||
States should not allow patents to restrict development and use of
|
||||
software on general-purpose computers, but in those that do, we wish to
|
||||
avoid the special danger that patents applied to a free program could
|
||||
make it effectively proprietary. To prevent this, the GPL assures that
|
||||
patents cannot be used to render the program non-free.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
TERMS AND CONDITIONS
|
||||
|
||||
0. Definitions.
|
||||
|
||||
"This License" refers to version 3 of the GNU General Public License.
|
||||
|
||||
"Copyright" also means copyright-like laws that apply to other kinds of
|
||||
works, such as semiconductor masks.
|
||||
|
||||
"The Program" refers to any copyrightable work licensed under this
|
||||
License. Each licensee is addressed as "you". "Licensees" and
|
||||
"recipients" may be individuals or organizations.
|
||||
|
||||
To "modify" a work means to copy from or adapt all or part of the work
|
||||
in a fashion requiring copyright permission, other than the making of an
|
||||
exact copy. The resulting work is called a "modified version" of the
|
||||
earlier work or a work "based on" the earlier work.
|
||||
|
||||
A "covered work" means either the unmodified Program or a work based
|
||||
on the Program.
|
||||
|
||||
To "propagate" a work means to do anything with it that, without
|
||||
permission, would make you directly or secondarily liable for
|
||||
infringement under applicable copyright law, except executing it on a
|
||||
computer or modifying a private copy. Propagation includes copying,
|
||||
distribution (with or without modification), making available to the
|
||||
public, and in some countries other activities as well.
|
||||
|
||||
To "convey" a work means any kind of propagation that enables other
|
||||
parties to make or receive copies. Mere interaction with a user through
|
||||
a computer network, with no transfer of a copy, is not conveying.
|
||||
|
||||
An interactive user interface displays "Appropriate Legal Notices"
|
||||
to the extent that it includes a convenient and prominently visible
|
||||
feature that (1) displays an appropriate copyright notice, and (2)
|
||||
tells the user that there is no warranty for the work (except to the
|
||||
extent that warranties are provided), that licensees may convey the
|
||||
work under this License, and how to view a copy of this License. If
|
||||
the interface presents a list of user commands or options, such as a
|
||||
menu, a prominent item in the list meets this criterion.
|
||||
|
||||
1. Source Code.
|
||||
|
||||
The "source code" for a work means the preferred form of the work
|
||||
for making modifications to it. "Object code" means any non-source
|
||||
form of a work.
|
||||
|
||||
A "Standard Interface" means an interface that either is an official
|
||||
standard defined by a recognized standards body, or, in the case of
|
||||
interfaces specified for a particular programming language, one that
|
||||
is widely used among developers working in that language.
|
||||
|
||||
The "System Libraries" of an executable work include anything, other
|
||||
than the work as a whole, that (a) is included in the normal form of
|
||||
packaging a Major Component, but which is not part of that Major
|
||||
Component, and (b) serves only to enable use of the work with that
|
||||
Major Component, or to implement a Standard Interface for which an
|
||||
implementation is available to the public in source code form. A
|
||||
"Major Component", in this context, means a major essential component
|
||||
(kernel, window system, and so on) of the specific operating system
|
||||
(if any) on which the executable work runs, or a compiler used to
|
||||
produce the work, or an object code interpreter used to run it.
|
||||
|
||||
The "Corresponding Source" for a work in object code form means all
|
||||
the source code needed to generate, install, and (for an executable
|
||||
work) run the object code and to modify the work, including scripts to
|
||||
control those activities. However, it does not include the work's
|
||||
System Libraries, or general-purpose tools or generally available free
|
||||
programs which are used unmodified in performing those activities but
|
||||
which are not part of the work. For example, Corresponding Source
|
||||
includes interface definition files associated with source files for
|
||||
the work, and the source code for shared libraries and dynamically
|
||||
linked subprograms that the work is specifically designed to require,
|
||||
such as by intimate data communication or control flow between those
|
||||
subprograms and other parts of the work.
|
||||
|
||||
The Corresponding Source need not include anything that users
|
||||
can regenerate automatically from other parts of the Corresponding
|
||||
Source.
|
||||
|
||||
The Corresponding Source for a work in source code form is that
|
||||
same work.
|
||||
|
||||
2. Basic Permissions.
|
||||
|
||||
All rights granted under this License are granted for the term of
|
||||
copyright on the Program, and are irrevocable provided the stated
|
||||
conditions are met. This License explicitly affirms your unlimited
|
||||
permission to run the unmodified Program. The output from running a
|
||||
covered work is covered by this License only if the output, given its
|
||||
content, constitutes a covered work. This License acknowledges your
|
||||
rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not
|
||||
convey, without conditions so long as your license otherwise remains
|
||||
in force. You may convey covered works to others for the sole purpose
|
||||
of having them make modifications exclusively for you, or provide you
|
||||
with facilities for running those works, provided that you comply with
|
||||
the terms of this License in conveying all material for which you do
|
||||
not control copyright. Those thus making or running the covered works
|
||||
for you must do so exclusively on your behalf, under your direction
|
||||
and control, on terms that prohibit them from making any copies of
|
||||
your copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under
|
||||
the conditions stated below. Sublicensing is not allowed; section 10
|
||||
makes it unnecessary.
|
||||
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
|
||||
No covered work shall be deemed part of an effective technological
|
||||
measure under any applicable law fulfilling obligations under article
|
||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
||||
similar laws prohibiting or restricting circumvention of such
|
||||
measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid
|
||||
circumvention of technological measures to the extent such circumvention
|
||||
is effected by exercising rights under this License with respect to
|
||||
the covered work, and you disclaim any intention to limit operation or
|
||||
modification of the work as a means of enforcing, against the work's
|
||||
users, your or third parties' legal rights to forbid circumvention of
|
||||
technological measures.
|
||||
|
||||
4. Conveying Verbatim Copies.
|
||||
|
||||
You may convey 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;
|
||||
keep intact all notices stating that this License and any
|
||||
non-permissive terms added in accord with section 7 apply to the code;
|
||||
keep intact all notices of the absence of any warranty; and give all
|
||||
recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey,
|
||||
and you may offer support or warranty protection for a fee.
|
||||
|
||||
5. Conveying Modified Source Versions.
|
||||
|
||||
You may convey a work based on the Program, or the modifications to
|
||||
produce it from the Program, in the form of source code under the
|
||||
terms of section 4, provided that you also meet all of these conditions:
|
||||
|
||||
a) The work must carry prominent notices stating that you modified
|
||||
it, and giving a relevant date.
|
||||
|
||||
b) The work must carry prominent notices stating that it is
|
||||
released under this License and any conditions added under section
|
||||
7. This requirement modifies the requirement in section 4 to
|
||||
"keep intact all notices".
|
||||
|
||||
c) You must license the entire work, as a whole, under this
|
||||
License to anyone who comes into possession of a copy. This
|
||||
License will therefore apply, along with any applicable section 7
|
||||
additional terms, to the whole of the work, and all its parts,
|
||||
regardless of how they are packaged. This License gives no
|
||||
permission to license the work in any other way, but it does not
|
||||
invalidate such permission if you have separately received it.
|
||||
|
||||
d) If the work has interactive user interfaces, each must display
|
||||
Appropriate Legal Notices; however, if the Program has interactive
|
||||
interfaces that do not display Appropriate Legal Notices, your
|
||||
work need not make them do so.
|
||||
|
||||
A compilation of a covered work with other separate and independent
|
||||
works, which are not by their nature extensions of the covered work,
|
||||
and which are not combined with it such as to form a larger program,
|
||||
in or on a volume of a storage or distribution medium, is called an
|
||||
"aggregate" if the compilation and its resulting copyright are not
|
||||
used to limit the access or legal rights of the compilation's users
|
||||
beyond what the individual works permit. Inclusion of a covered work
|
||||
in an aggregate does not cause this License to apply to the other
|
||||
parts of the aggregate.
|
||||
|
||||
6. Conveying Non-Source Forms.
|
||||
|
||||
You may convey a covered work in object code form under the terms
|
||||
of sections 4 and 5, provided that you also convey the
|
||||
machine-readable Corresponding Source under the terms of this License,
|
||||
in one of these ways:
|
||||
|
||||
a) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by the
|
||||
Corresponding Source fixed on a durable physical medium
|
||||
customarily used for software interchange.
|
||||
|
||||
b) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by a
|
||||
written offer, valid for at least three years and valid for as
|
||||
long as you offer spare parts or customer support for that product
|
||||
model, to give anyone who possesses the object code either (1) a
|
||||
copy of the Corresponding Source for all the software in the
|
||||
product that is covered by this License, on a durable physical
|
||||
medium customarily used for software interchange, for a price no
|
||||
more than your reasonable cost of physically performing this
|
||||
conveying of source, or (2) access to copy the
|
||||
Corresponding Source from a network server at no charge.
|
||||
|
||||
c) Convey individual copies of the object code with a copy of the
|
||||
written offer to provide the Corresponding Source. This
|
||||
alternative is allowed only occasionally and noncommercially, and
|
||||
only if you received the object code with such an offer, in accord
|
||||
with subsection 6b.
|
||||
|
||||
d) Convey the object code by offering access from a designated
|
||||
place (gratis or for a charge), and offer equivalent access to the
|
||||
Corresponding Source in the same way through the same place at no
|
||||
further charge. You need not require recipients to copy the
|
||||
Corresponding Source along with the object code. If the place to
|
||||
copy the object code is a network server, the Corresponding Source
|
||||
may be on a different server (operated by you or a third party)
|
||||
that supports equivalent copying facilities, provided you maintain
|
||||
clear directions next to the object code saying where to find the
|
||||
Corresponding Source. Regardless of what server hosts the
|
||||
Corresponding Source, you remain obligated to ensure that it is
|
||||
available for as long as needed to satisfy these requirements.
|
||||
|
||||
e) Convey the object code using peer-to-peer transmission, provided
|
||||
you inform other peers where the object code and Corresponding
|
||||
Source of the work are being offered to the general public at no
|
||||
charge under subsection 6d.
|
||||
|
||||
A separable portion of the object code, whose source code is excluded
|
||||
from the Corresponding Source as a System Library, need not be
|
||||
included in conveying the object code work.
|
||||
|
||||
A "User Product" is either (1) a "consumer product", which means any
|
||||
tangible personal property which is normally used for personal, family,
|
||||
or household purposes, or (2) anything designed or sold for incorporation
|
||||
into a dwelling. In determining whether a product is a consumer product,
|
||||
doubtful cases shall be resolved in favor of coverage. For a particular
|
||||
product received by a particular user, "normally used" refers to a
|
||||
typical or common use of that class of product, regardless of the status
|
||||
of the particular user or of the way in which the particular user
|
||||
actually uses, or expects or is expected to use, the product. A product
|
||||
is a consumer product regardless of whether the product has substantial
|
||||
commercial, industrial or non-consumer uses, unless such uses represent
|
||||
the only significant mode of use of the product.
|
||||
|
||||
"Installation Information" for a User Product means any methods,
|
||||
procedures, authorization keys, or other information required to install
|
||||
and execute modified versions of a covered work in that User Product from
|
||||
a modified version of its Corresponding Source. The information must
|
||||
suffice to ensure that the continued functioning of the modified object
|
||||
code is in no case prevented or interfered with solely because
|
||||
modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or
|
||||
specifically for use in, a User Product, and the conveying occurs as
|
||||
part of a transaction in which the right of possession and use of the
|
||||
User Product is transferred to the recipient in perpetuity or for a
|
||||
fixed term (regardless of how the transaction is characterized), the
|
||||
Corresponding Source conveyed under this section must be accompanied
|
||||
by the Installation Information. But this requirement does not apply
|
||||
if neither you nor any third party retains the ability to install
|
||||
modified object code on the User Product (for example, the work has
|
||||
been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include a
|
||||
requirement to continue to provide support service, warranty, or updates
|
||||
for a work that has been modified or installed by the recipient, or for
|
||||
the User Product in which it has been modified or installed. Access to a
|
||||
network may be denied when the modification itself materially and
|
||||
adversely affects the operation of the network or violates the rules and
|
||||
protocols for communication across the network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided,
|
||||
in accord with this section must be in a format that is publicly
|
||||
documented (and with an implementation available to the public in
|
||||
source code form), and must require no special password or key for
|
||||
unpacking, reading or copying.
|
||||
|
||||
7. Additional Terms.
|
||||
|
||||
"Additional permissions" are terms that supplement the terms of this
|
||||
License by making exceptions from one or more of its conditions.
|
||||
Additional permissions that are applicable to the entire Program shall
|
||||
be treated as though they were included in this License, to the extent
|
||||
that they are valid under applicable law. If additional permissions
|
||||
apply only to part of the Program, that part may be used separately
|
||||
under those permissions, but the entire Program remains governed by
|
||||
this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option
|
||||
remove any additional permissions from that copy, or from any part of
|
||||
it. (Additional permissions may be written to require their own
|
||||
removal in certain cases when you modify the work.) You may place
|
||||
additional permissions on material, added by you to a covered work,
|
||||
for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you
|
||||
add to a covered work, you may (if authorized by the copyright holders of
|
||||
that material) supplement the terms of this License with terms:
|
||||
|
||||
a) Disclaiming warranty or limiting liability differently from the
|
||||
terms of sections 15 and 16 of this License; or
|
||||
|
||||
b) Requiring preservation of specified reasonable legal notices or
|
||||
author attributions in that material or in the Appropriate Legal
|
||||
Notices displayed by works containing it; or
|
||||
|
||||
c) Prohibiting misrepresentation of the origin of that material, or
|
||||
requiring that modified versions of such material be marked in
|
||||
reasonable ways as different from the original version; or
|
||||
|
||||
d) Limiting the use for publicity purposes of names of licensors or
|
||||
authors of the material; or
|
||||
|
||||
e) Declining to grant rights under trademark law for use of some
|
||||
trade names, trademarks, or service marks; or
|
||||
|
||||
f) Requiring indemnification of licensors and authors of that
|
||||
material by anyone who conveys the material (or modified versions of
|
||||
it) with contractual assumptions of liability to the recipient, for
|
||||
any liability that these contractual assumptions directly impose on
|
||||
those licensors and authors.
|
||||
|
||||
All other non-permissive additional terms are considered "further
|
||||
restrictions" within the meaning of section 10. If the Program as you
|
||||
received it, or any part of it, contains a notice stating that it is
|
||||
governed by this License along with a term that is a further
|
||||
restriction, you may remove that term. If a license document contains
|
||||
a further restriction but permits relicensing or conveying under this
|
||||
License, you may add to a covered work material governed by the terms
|
||||
of that license document, provided that the further restriction does
|
||||
not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you
|
||||
must place, in the relevant source files, a statement of the
|
||||
additional terms that apply to those files, or a notice indicating
|
||||
where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the
|
||||
form of a separately written license, or stated as exceptions;
|
||||
the above requirements apply either way.
|
||||
|
||||
8. Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly
|
||||
provided under this License. Any attempt otherwise to propagate or
|
||||
modify it is void, and will automatically terminate your rights under
|
||||
this License (including any patent licenses granted under the third
|
||||
paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your
|
||||
license from a particular copyright holder is reinstated (a)
|
||||
provisionally, unless and until the copyright holder explicitly and
|
||||
finally terminates your license, and (b) permanently, if the copyright
|
||||
holder fails to notify you of the violation by some reasonable means
|
||||
prior to 60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is
|
||||
reinstated permanently if the copyright holder notifies you of the
|
||||
violation by some reasonable means, this is the first time you have
|
||||
received notice of violation of this License (for any work) from that
|
||||
copyright holder, and you cure the violation prior to 30 days after
|
||||
your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate the
|
||||
licenses of parties who have received copies or rights from you under
|
||||
this License. If your rights have been terminated and not permanently
|
||||
reinstated, you do not qualify to receive new licenses for the same
|
||||
material under section 10.
|
||||
|
||||
9. Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or
|
||||
run a copy of the Program. Ancillary propagation of a covered work
|
||||
occurring solely as a consequence of using peer-to-peer transmission
|
||||
to receive a copy likewise does not require acceptance. However,
|
||||
nothing other than this License grants you permission to propagate or
|
||||
modify any covered work. These actions infringe copyright if you do
|
||||
not accept this License. Therefore, by modifying or propagating a
|
||||
covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
10. Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically
|
||||
receives a license from the original licensors, to run, modify and
|
||||
propagate that work, subject to this License. You are not responsible
|
||||
for enforcing compliance by third parties with this License.
|
||||
|
||||
An "entity transaction" is a transaction transferring control of an
|
||||
organization, or substantially all assets of one, or subdividing an
|
||||
organization, or merging organizations. If propagation of a covered
|
||||
work results from an entity transaction, each party to that
|
||||
transaction who receives a copy of the work also receives whatever
|
||||
licenses to the work the party's predecessor in interest had or could
|
||||
give under the previous paragraph, plus a right to possession of the
|
||||
Corresponding Source of the work from the predecessor in interest, if
|
||||
the predecessor has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the
|
||||
rights granted or affirmed under this License. For example, you may
|
||||
not impose a license fee, royalty, or other charge for exercise of
|
||||
rights granted under this License, and you may not initiate litigation
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
||||
any patent claim is infringed by making, using, selling, offering for
|
||||
sale, or importing the Program or any portion of it.
|
||||
|
||||
11. Patents.
|
||||
|
||||
A "contributor" is a copyright holder who authorizes use under this
|
||||
License of the Program or a work on which the Program is based. The
|
||||
work thus licensed is called the contributor's "contributor version".
|
||||
|
||||
A contributor's "essential patent claims" are all patent claims
|
||||
owned or controlled by the contributor, whether already acquired or
|
||||
hereafter acquired, that would be infringed by some manner, permitted
|
||||
by this License, of making, using, or selling its contributor version,
|
||||
but do not include claims that would be infringed only as a
|
||||
consequence of further modification of the contributor version. For
|
||||
purposes of this definition, "control" includes the right to grant
|
||||
patent sublicenses in a manner consistent with the requirements of
|
||||
this License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||
patent license under the contributor's essential patent claims, to
|
||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
||||
propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a "patent license" is any express
|
||||
agreement or commitment, however denominated, not to enforce a patent
|
||||
(such as an express permission to practice a patent or covenant not to
|
||||
sue for patent infringement). To "grant" such a patent license to a
|
||||
party means to make such an agreement or commitment not to enforce a
|
||||
patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license,
|
||||
and the Corresponding Source of the work is not available for anyone
|
||||
to copy, free of charge and under the terms of this License, through a
|
||||
publicly available network server or other readily accessible means,
|
||||
then you must either (1) cause the Corresponding Source to be so
|
||||
available, or (2) arrange to deprive yourself of the benefit of the
|
||||
patent license for this particular work, or (3) arrange, in a manner
|
||||
consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. "Knowingly relying" means you have
|
||||
actual knowledge that, but for the patent license, your conveying the
|
||||
covered work in a country, or your recipient's use of the covered work
|
||||
in a country, would infringe one or more identifiable patents in that
|
||||
country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or
|
||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
||||
covered work, and grant a patent license to some of the parties
|
||||
receiving the covered work authorizing them to use, propagate, modify
|
||||
or convey a specific copy of the covered work, then the patent license
|
||||
you grant is automatically extended to all recipients of the covered
|
||||
work and works based on it.
|
||||
|
||||
A patent license is "discriminatory" if it does not include within
|
||||
the scope of its coverage, prohibits the exercise of, or is
|
||||
conditioned on the non-exercise of one or more of the rights that are
|
||||
specifically granted under this License. You may not convey a covered
|
||||
work if you are a party to an arrangement with a third party that is
|
||||
in the business of distributing software, under which you make payment
|
||||
to the third party based on the extent of your activity of conveying
|
||||
the work, and under which the third party grants, to any of the
|
||||
parties who would receive the covered work from you, a discriminatory
|
||||
patent license (a) in connection with copies of the covered work
|
||||
conveyed by you (or copies made from those copies), or (b) primarily
|
||||
for and in connection with specific products or compilations that
|
||||
contain the covered work, unless you entered into that arrangement,
|
||||
or that patent license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting
|
||||
any implied license or other defenses to infringement that may
|
||||
otherwise be available to you under applicable patent law.
|
||||
|
||||
12. No Surrender of Others' Freedom.
|
||||
|
||||
If 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 convey a
|
||||
covered work so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you may
|
||||
not convey it at all. For example, if you agree to terms that obligate you
|
||||
to collect a royalty for further conveying from those to whom you convey
|
||||
the Program, the only way you could satisfy both those terms and this
|
||||
License would be to refrain entirely from conveying the Program.
|
||||
|
||||
13. Use with the GNU Affero General Public License.
|
||||
|
||||
Notwithstanding any other provision of this License, you have
|
||||
permission to link or combine any covered work with a work licensed
|
||||
under version 3 of the GNU Affero General Public License into a single
|
||||
combined work, and to convey the resulting work. The terms of this
|
||||
License will continue to apply to the part which is the covered work,
|
||||
but the special requirements of the GNU Affero General Public License,
|
||||
section 13, concerning interaction through a network will apply to the
|
||||
combination as such.
|
||||
|
||||
14. Revised Versions of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions of
|
||||
the GNU 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 that a certain numbered version of the GNU General
|
||||
Public License "or any later version" applies to it, you have the
|
||||
option of following the terms and conditions either of that numbered
|
||||
version or of any later version published by the Free Software
|
||||
Foundation. If the Program does not specify a version number of the
|
||||
GNU General Public License, you may choose any version ever published
|
||||
by the Free Software Foundation.
|
||||
|
||||
If the Program specifies that a proxy can decide which future
|
||||
versions of the GNU General Public License can be used, that proxy's
|
||||
public statement of acceptance of a version permanently authorizes you
|
||||
to choose that version for the Program.
|
||||
|
||||
Later license versions may give you additional or different
|
||||
permissions. However, no additional obligations are imposed on any
|
||||
author or copyright holder as a result of your choosing to follow a
|
||||
later version.
|
||||
|
||||
15. Disclaimer of Warranty.
|
||||
|
||||
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.
|
||||
|
||||
16. Limitation of Liability.
|
||||
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
||||
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.
|
||||
|
||||
17. Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided
|
||||
above cannot be given local legal effect according to their terms,
|
||||
reviewing courts shall apply local law that most closely approximates
|
||||
an absolute waiver of all civil liability in connection with the
|
||||
Program, unless a warranty or assumption of liability accompanies a
|
||||
copy of the Program in return for a fee.
|
||||
|
||||
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
|
||||
state 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 3 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, see <https://www.gnu.org/licenses/>.
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program does terminal interaction, make it output a short
|
||||
notice like this when it starts in an interactive mode:
|
||||
|
||||
<program> Copyright (C) <year> <name of author>
|
||||
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, your program's commands
|
||||
might be different; for a GUI interface, you would use an "about box".
|
||||
|
||||
You should also get your employer (if you work as a programmer) or school,
|
||||
if any, to sign a "copyright disclaimer" for the program, if necessary.
|
||||
For more information on this, and how to apply and follow the GNU GPL, see
|
||||
<https://www.gnu.org/licenses/>.
|
||||
|
||||
The GNU General Public License does not permit incorporating your program
|
||||
into proprietary programs. If your program is a subroutine library, you
|
||||
may consider it more useful to permit linking proprietary applications with
|
||||
the library. If this is what you want to do, use the GNU Lesser General
|
||||
Public License instead of this License. But first, please read

GNU LESSER GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates
|
||||
the terms and conditions of version 3 of the GNU General Public
|
||||
License, supplemented by the additional permissions listed below.
|
||||
|
||||
0. Additional Definitions.
|
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser
|
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU
|
||||
General Public License.
|
||||
|
||||
"The Library" refers to a covered work governed by this License,
|
||||
other than an Application or a Combined Work as defined below.
|
||||
|
||||
An "Application" is any work that makes use of an interface provided
|
||||
by the Library, but which is not otherwise based on the Library.
|
||||
Defining a subclass of a class defined by the Library is deemed a mode
|
||||
of using an interface provided by the Library.
|
||||
|
||||
A "Combined Work" is a work produced by combining or linking an
|
||||
Application with the Library. The particular version of the Library
|
||||
with which the Combined Work was made is also called the "Linked
|
||||
Version".
|
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the
|
||||
Corresponding Source for the Combined Work, excluding any source code
|
||||
for portions of the Combined Work that, considered in isolation, are
|
||||
based on the Application, and not on the Linked Version.
|
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the
|
||||
object code and/or source code for the Application, including any data
|
||||
and utility programs needed for reproducing the Combined Work from the
|
||||
Application, but excluding the System Libraries of the Combined Work.
|
||||
|
||||
1. Exception to Section 3 of the GNU GPL.
|
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License
|
||||
without being bound by section 3 of the GNU GPL.
|
||||
|
||||
2. Conveying Modified Versions.
|
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a
|
||||
facility refers to a function or data to be supplied by an Application
|
||||
that uses the facility (other than as an argument passed when the
|
||||
facility is invoked), then you may convey a copy of the modified
|
||||
version:
|
||||
|
||||
a) under this License, provided that you make a good faith effort to
|
||||
ensure that, in the event an Application does not supply the
|
||||
function or data, the facility still operates, and performs
|
||||
whatever part of its purpose remains meaningful, or
|
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of
|
||||
this License applicable to that copy.
|
||||
|
||||
3. Object Code Incorporating Material from Library Header Files.
|
||||
|
||||
The object code form of an Application may incorporate material from
|
||||
a header file that is part of the Library. You may convey such object
|
||||
code under terms of your choice, provided that, if the incorporated
|
||||
material is not limited to numerical parameters, data structure
|
||||
layouts and accessors, or small macros, inline functions and templates
|
||||
(ten or fewer lines in length), you do both of the following:
|
||||
|
||||
a) Give prominent notice with each copy of the object code that the
|
||||
Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
4. Combined Works.
|
||||
|
||||
You may convey a Combined Work under terms of your choice that,
|
||||
taken together, effectively do not restrict modification of the
|
||||
portions of the Library contained in the Combined Work and reverse
|
||||
engineering for debugging such modifications, if you also do each of
|
||||
the following:
|
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that
|
||||
the Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
c) For a Combined Work that displays copyright notices during
|
||||
execution, include the copyright notice for the Library among
|
||||
these notices, as well as a reference directing the user to the
|
||||
copies of the GNU GPL and this license document.
|
||||
|
||||
d) Do one of the following:
|
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this
|
||||
License, and the Corresponding Application Code in a form
|
||||
suitable for, and under terms that permit, the user to
|
||||
recombine or relink the Application with a modified version of
|
||||
the Linked Version to produce a modified Combined Work, in the
|
||||
manner specified by section 6 of the GNU GPL for conveying
|
||||
Corresponding Source.
|
||||
|
||||
1) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (a) uses at run time
|
||||
a copy of the Library already present on the user's computer
|
||||
system, and (b) will operate properly with a modified version
|
||||
of the Library that is interface-compatible with the Linked
|
||||
Version.
|
||||
|
||||
e) Provide Installation Information, but only if you would otherwise
|
||||
be required to provide such information under section 6 of the
|
||||
GNU GPL, and only to the extent that such information is
|
||||
necessary to install and execute a modified version of the
|
||||
Combined Work produced by recombining or relinking the
|
||||
Application with a modified version of the Linked Version. (If
|
||||
you use option 4d0, the Installation Information must accompany
|
||||
the Minimal Corresponding Source and Corresponding Application
|
||||
Code. If you use option 4d1, you must provide the Installation
|
||||
Information in the manner specified by section 6 of the GNU GPL
|
||||
for conveying Corresponding Source.)
|
||||
|
||||
5. Combined Libraries.
|
||||
|
||||
You may place library facilities that are a work based on the
|
||||
Library side by side in a single library together with other library
|
||||
facilities that are not Applications and are not covered by this
|
||||
License, and convey such a combined library under terms of your
|
||||
choice, if you do both of the following:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work based
|
||||
on the Library, uncombined with any other library facilities,
|
||||
conveyed under the terms of this License.
|
||||
|
||||
b) Give prominent notice with the combined library that part of it
|
||||
is a work based on the Library, and explaining where to find the
|
||||
accompanying uncombined form of the same work.
|
||||
|
||||
6. Revised Versions of the GNU Lesser General Public License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions
|
||||
of the GNU Lesser 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
|
||||
Library as you received it specifies that a certain numbered version
|
||||
of the GNU Lesser General Public License "or any later version"
|
||||
applies to it, you have the option of following the terms and
|
||||
conditions either of that published version or of any later version
|
||||
published by the Free Software Foundation. If the Library as you
|
||||
received it does not specify a version number of the GNU Lesser
|
||||
General Public License, you may choose any version of the GNU Lesser
|
||||
General Public License ever published by the Free Software Foundation.
|
||||
|
||||
If the Library as you received it specifies that a proxy can decide
|
||||
whether future versions of the GNU Lesser General Public License shall
|
||||
apply, that proxy's public statement of acceptance of any version is
|
||||
permanent authorization for you to choose that version for the
|
||||
Library.

##############################################################################
|
||||
|
||||
Changes from version 4.2.1 to version 4.2.2:
|
||||
- In order to resolve a portability issue with the _Float128 fallback to
|
||||
__float128 for binary128 support (e.g. with Clang and glibc 2.41), the
|
||||
prototypes of the corresponding conversion functions had to be changed,
|
||||
with _Float128 replaced by mpfr_float128, where mpfr_float128 is a macro
|
||||
defined as _Float128 by default. This changes neither the ABI nor the API
|
||||
(except that the end user of MPFR would need to define mpfr_float128 as
|
||||
the actual type for the binary128 format if this is not the standard
|
||||
_Float128 type).
|
||||
- Other bug fixes (see <https://www.mpfr.org/mpfr-4.2.1/#fixed> and/or the
|
||||
ChangeLog file). In particular, the formatted output functions behaved
|
||||
incorrectly with %c on the value 0; such a use is uncommon, but this bug
|
||||
may have security implications.
|
||||
- Improved MPFR manual.
|
||||
- Detect the use of GMP's buggy vsnprintf replacement at configure time.
|
||||
With it, the tests of "%a" will be disabled to avoid an assertion failure
|
||||
in the MPFR testsuite. A warning will be displayed in the configure output
|
||||
in such a case.
|
||||
|
||||
Changes from version 4.2.0 to version 4.2.1:
|
||||
- Bug fixes (see <https://www.mpfr.org/mpfr-4.2.0/#fixed> and/or the
|
||||
ChangeLog file).
|
||||
- Improved MPFR manual.
|
||||
- Configure tests: replaced the test of the link with GMP, in order to
|
||||
avoid the use of a function without a prototype (Autoconf issue), as
|
||||
this is obsolescent in ISO C. The new test should be more robust.
|
||||
|
||||
Changes from versions 4.1.* to version 4.2.0:
|
||||
- The "fondue savoyarde" release.
|
||||
- Binary compatible with MPFR 4.0.* and 4.1.*, though some minor changes in
|
||||
the behavior of the formatted output functions may be visible, regarded
|
||||
as underspecified behavior or bug fixes (see below).
|
||||
- New functions mpfr_cosu, mpfr_sinu, mpfr_tanu, mpfr_acosu, mpfr_asinu,
|
||||
mpfr_atanu and mpfr_atan2u.
|
||||
- New functions mpfr_cospi, mpfr_sinpi, mpfr_tanpi, mpfr_acospi, mpfr_asinpi,
|
||||
mpfr_atanpi and mpfr_atan2pi.
|
||||
- New functions mpfr_log2p1, mpfr_log10p1, mpfr_exp2m1, mpfr_exp10m1 and
|
||||
mpfr_compound_si.
|
||||
- New functions mpfr_fmod_ui, mpfr_powr, mpfr_pown, mpfr_pow_uj, mpfr_pow_sj
|
||||
and mpfr_rootn_si (mpfr_pown is actually a macro defined as an alias for
|
||||
mpfr_pow_sj).
|
||||
- Bug fixes.
|
||||
In particular, for the formatted output functions (mpfr_printf, etc.),
|
||||
the case where the precision consists only of a period has been fixed
|
||||
to be like ".0" as specified in the ISO C standard, and the manual has
|
||||
been corrected and clarified.
|
||||
The macros of the custom interface have also been fixed: they now behave
|
||||
like functions (except a minor limitation for mpfr_custom_init_set).
|
||||
|
||||
Changes from versions 4.0.* to version 4.1.0:
|
||||
- The "épinards à la crème" release.
|
||||
- Binary compatible with MPFR 4.0.*, though some minor changes in the
|
||||
behavior of the formatted output functions may be visible, regarded
|
||||
as underspecified behavior or bug fixes (see below).
|
||||
- New --enable-formally-proven-code configure option, to use (when available)
|
||||
formally proven code.
|
||||
- Improved __GMP_CC and __GMP_CFLAGS retrieval (in particular for MS Windows).
|
||||
- Option -pedantic is now always removed from __GMP_CFLAGS (see INSTALL).
|
||||
- Changed __float128 to the type _Float128 specified in ISO/IEC TS 18661.
|
||||
__float128 is used as a fallback if _Float128 is not supported.
|
||||
- New function mpfr_get_str_ndigits about conversion to a string of digits.
|
||||
- New function mpfr_dot for the dot product (incomplete, experimental).
|
||||
- New functions mpfr_get_decimal128 and mpfr_set_decimal128 (available only
|
||||
when MPFR has been built with decimal float support).
|
||||
- New function mpfr_cmpabs_ui.
|
||||
- New function mpfr_total_order_p for the IEEE 754 totalOrder predicate.
|
||||
- The mpfr_out_str function now accepts bases from -2 to -36, in order to
|
||||
follow mpfr_get_str and GMP's mpf_out_str functions (these cases gave an
|
||||
assertion failure, as with other invalid bases).
|
||||
- Shared caches: cleanup; really detect lock failures (abort in this case).
|
||||
- The behavior of the formatted output functions (mpfr_printf, etc.) with
|
||||
an empty precision field has improved: trailing zeros are kept in a way
|
||||
similar to the formatted output functions from C.
|
||||
- Improved mpfr_add and mpfr_sub when all operands have a precision equal to
|
||||
twice the number of bits per word, e.g., 128 bits on a 64-bit platform.
|
||||
- Optimized the tuning parameters for various architectures.
|
||||
- Improved test coverage to 98.6% of code for x86_64.
|
||||
- Bug fixes.
|
||||
- MPFR manual: corrected/completed the mpfr_get_str description in order to
|
||||
follow the historical behavior and GMP's mpf_get_str function.
|
||||
- New: optional "make check-exported-symbols", mainly for the MPFR developers
|
||||
and binary distributions, to check that MPFR does not define symbols with a
|
||||
GMP reserved prefix (experimental).
|
||||
- Mini-gmp support: replaced --enable-mini-gmp configure option by
|
||||
--with-mini-gmp (still experimental, read doc/mini-gmp).
|
||||
- A GCC bug on Sparc (present at least in old GCC 4.5.3 and 5.5.0 versions),
|
||||
which made several tests fail when TLS was enabled, is now avoided in the
|
||||
tests. The MPFR library itself was not affected and normal code using the
|
||||
MPFR library should not be affected either. Users and distributions that
|
||||
disabled TLS just because of the test failures can safely re-enable it.
|
||||
|
||||
Changes from versions 3.1.* to version 4.0.0:
|
||||
- The "dinde aux marrons" release.
|
||||
- MPFR now depends on GMP 5.0+ instead of 4.1+.
|
||||
- API change:
|
||||
Applications that call GMP's mp_set_memory_functions function to change
|
||||
the allocators must first call the new function mpfr_mp_memory_cleanup
|
||||
in all threads where MPFR is potentially used; this new function is
|
||||
currently equivalent to mpfr_free_cache.
|
||||
The reason is that the way memory allocation is done by MPFR has changed
|
||||
(again), so that the current GMP allocators are used (since for some
|
||||
applications, the old allocators may become invalid).
|
||||
Note: Freeing the caches like this might have a performance impact on some
|
||||
particular applications; if this is an issue, this could be handled for a
|
||||
future MPFR version.
|
||||
- Mini-gmp support via the --enable-mini-gmp configure option (experimental).
|
||||
- The minimum precision MPFR_PREC_MIN is now 1, with rounding defined as
|
||||
in the errata of IEEE 754-2008 and in the following IEEE 754 revision
|
||||
(ties rounded away from zero).
|
||||
- Shared caches for multithreaded applications.
|
||||
New function mpfr_free_cache2.
|
||||
- Partial support of MPFR_RNDF (faithful rounding).
|
||||
- New functions: mpfr_fpif_export and mpfr_fpif_import to export and import
|
||||
numbers in a floating-point interchange format, independent both on the
|
||||
number of bits per word and on the endianness.
|
||||
- New function mpfr_fmodquo to return the low bits of the quotient
|
||||
corresponding to mpfr_fmod.
|
||||
- New functions mpfr_flags_clear, mpfr_flags_set, mpfr_flags_test,
|
||||
mpfr_flags_save and mpfr_flags_restore to operate on groups of flags.
|
||||
- New functions mpfr_set_float128 and mpfr_get_float128 to convert from/to
|
||||
the __float128 type (requires --enable-float128 and compiler support).
|
||||
- New functions mpfr_buildopt_float128_p and mpfr_buildopt_sharedcache_p.
|
||||
- New functions mpfr_rint_roundeven and mpfr_roundeven, completing the
|
||||
other similar round-to-integer functions for rounding to nearest with
|
||||
the even-rounding rule.
|
||||
- New macro mpfr_round_nearest_away to add partial emulation of the
|
||||
rounding to nearest-away (as defined in IEEE 754-2008).
|
||||
- New functions mpfr_nrandom and mpfr_erandom to generate random numbers
|
||||
following normal and exponential distributions respectively.
|
||||
- New functions mpfr_fmma and mpfr_fmms to compute a*b+c*d and a*b-c*d.
|
||||
- New function mpfr_rootn_ui, similar to mpfr_root, but agreeing with the
|
||||
rootn function of the IEEE 754-2008 standard.
|
||||
- New functions mpfr_log_ui to compute the logarithm of an integer,
|
||||
mpfr_gamma_inc for the incomplete Gamma function.
|
||||
- New function mpfr_beta for the Beta function (incomplete, experimental).
|
||||
- New function mpfr_get_q to convert a floating-point number into rational.
|
||||
- The mpfr_dump function is now described in the manual; its output format
|
||||
has slightly changed.
|
||||
- The mpfr_eint function now returns the value of the E1/eint1 function
|
||||
for negative argument.
|
||||
- The behavior of the mpfr_set_exp function changed, as it could easily
|
||||
yield undefined behavior in some cases (this modifies both the API and
|
||||
the ABI).
|
||||
- In function mpfr_urandom, the next random state no longer depends on the
|
||||
current exponent range and the rounding mode. The exceptions due to the
|
||||
rounding of the random number are now correctly generated, following the
|
||||
uniform distribution.
|
||||
- Functions mpfr_grandom and mpfr_root are deprecated and will be removed
|
||||
in a future release.
|
||||
- Complete rewrite of function mpfr_sum, which now works in all cases (the
|
||||
old one could take all the memory and/or crash with inputs of different
|
||||
magnitudes in case of huge cancellation or table maker's dilemma). The
|
||||
sign of an exact zero result is now specified, and the return value is
|
||||
now the usual ternary value. Note that the position of "const" in the
|
||||
mpfr_sum prototype has been fixed (the manual was correct); user code
|
||||
should not be affected.
|
||||
- Old, deprecated macros mpfr_add_one_ulp and mpfr_sub_one_ulp removed.
|
||||
The mpfr_next* functions should be used instead.
|
||||
- Internally, improved caching: a minimum of 10% increase of the precision
|
||||
is guaranteed to avoid too many recomputations.
|
||||
- Added internal small-precision mpz_t pool, which aims to avoid the
|
||||
overhead of memory allocation, in particular.
|
||||
New function mpfr_free_pool.
|
||||
- Added configure option --enable-assert=none to avoid checking any assertion.
|
||||
- The --enable-decimal-float configure option no longer requires
|
||||
--with-gmp-build, and support for decimal floats is now automatically
|
||||
detected by default (similarly for support for __float128).
|
||||
- Updated tuning parameters.
|
||||
- Better support for Automake 1.13+ (now used to generate the tarball).
|
||||
- Dropped K&R C compatibility.
|
||||
- Improved MPFR manual.
|
||||
- New MPFRbench program (see the tools/bench directory).
|
||||
- Major speedup in mpfr_add, mpfr_sub, mpfr_mul, mpfr_div and mpfr_sqrt when
|
||||
all operands have the same precision and this precision is less than twice
|
||||
the number of bits per word, e.g., less than 128 on a 64-bit computer.
|
||||
- Speedup by a factor of almost 2 in the double <--> mpfr conversions
|
||||
(mpfr_set_d and mpfr_get_d).
|
||||
- Speedup in mpfr_log1p and mpfr_atanh for small arguments.
|
||||
- Speedup in the mpfr_const_euler function (contributed by Fredrik Johansson),
|
||||
in the computation of Bernoulli numbers (used in mpfr_gamma, mpfr_li2,
|
||||
mpfr_digamma, mpfr_lngamma and mpfr_lgamma), in mpfr_div, in mpfr_fma
|
||||
and mpfr_fms.
|
||||
- Test coverage: 96.3% lines of code.
|
||||
- Bug fixes. In particular: a speed improvement when the --enable-assert
|
||||
or --enable-assert=full configure option is used with GCC; mpfr_get_str
|
||||
now sets the NaN flag on NaN input and the inexact flag when the conversion
|
||||
is inexact. For a full list, see https://www.mpfr.org/mpfr-3.1.6/#fixed
|
||||
and the same section for any previous 3.1.x version (follow the links
|
||||
in the "Changes..." sections).
|
||||
- Microsoft Windows: Added support for thread-safe DLL (shared library).
|
||||
Tested with MinGW, ICC and MSVC.
|
||||
- Limited pkg-config support.
|
||||
- Autotools: Under Linux, make sure that the old dtags (when supported)
|
||||
are used if LD_LIBRARY_PATH is defined; otherwise "make check" would
|
||||
check an installed, compatible MPFR library found in LD_LIBRARY_PATH
|
||||
instead of the one that has been built with "make".
|
||||
- New: optional "make check-gmp-symbols", mainly for binary distributions,
|
||||
to check that MPFR does not use GMP internal symbols (experimental).
|
||||
|
||||
Changes from versions 3.0.* to version 3.1.0:
|
||||
- The "canard à l'orange" release.
|
||||
- The MPFR source has been reorganized.
|
||||
- Dropped ansi2knr support.
|
||||
- TLS support is now detected automatically. If TLS is supported, MPFR is
|
||||
built as thread safe by default. To disable TLS explicitly, configure
|
||||
MPFR with --disable-thread-safe.
|
||||
- New --enable-gmp-internals configure option to use GMP's undocumented
|
||||
functions (not from the public API). Note that library versioning is
|
||||
not guaranteed to work if this option is used.
|
||||
- The mpfr_urandom and mpfr_urandomb functions now return identical values
|
||||
on processors with different word size (assuming the same random seed, and
|
||||
since the GMP random generator does not depend itself on the word size,
|
||||
cf https://gmplib.org/list-archives/gmp-devel/2010-September/001642.html).
|
||||
- The mpfr_add_one_ulp and mpfr_sub_one_ulp macros (which are obsolete and
|
||||
no more documented) will be removed in a future release.
|
||||
- Speed improvement for the mpfr_sqr and mpfr_div functions using Mulders'
|
||||
algorithm. As a consequence, other functions using those routines are
|
||||
also faster.
|
||||
- Much faster formatted output (mpfr_printf, etc.) with %Rg and similar.
|
||||
- The --with-gmp-build configure option can now be used when the GMP
|
||||
source directory and the GMP build directory are different (without
|
||||
having to copy header files manually as before).
|
||||
- New functions mpfr_buildopt_gmpinternals_p, mpfr_buildopt_tune_case,
|
||||
mpfr_frexp, mpfr_grandom and mpfr_z_sub.
|
||||
- New divide-by-zero exception (flag) and associated functions.
|
||||
- The mpfr.h header can be included several times, while still supporting
|
||||
optional functions (see Section "Headers and Libraries" in the manual).
|
||||
- Updated tuning parameters.
|
||||
- Improved MPFR manual.
|
||||
- MPFR tests: libtool no longer generates wrapper scripts with "make check"
|
||||
(so that running the tests under valgrind or gdb is easier).
|
||||
- Internal change: the logging mechanism has been improved.
|
||||
- Test coverage: 95.2% lines of code.
|
||||
- Bug fixes, in particular a huge inefficiency in mpfr_exp (when the
|
||||
target precision is less than MPFR_EXP_THRESHOLD) on hard-to-round
|
||||
cases, which can take several minutes.
|
||||
Note: The mpfr_subnormalize implementation up to MPFR 3.0.0 did not change
|
||||
the flags. In particular, it did not follow the generic rule concerning
|
||||
the inexact flag (and no special behavior was specified). The case of the
|
||||
underflow flag was more a lack of specification.
|
||||
|
||||
Changes from versions 2.4.* to version 3.0.0:
|
||||
- The "boudin aux pommes" release.
|
||||
- MPFR 3.0.0 is binary incompatible with previous versions but (almost)
|
||||
API compatible. More precisely the obsolete functions mpfr_random
|
||||
and mpfr_random2 have been removed, the meaning of the return type
|
||||
of the function mpfr_get_f has changed, and the return type of the
|
||||
function mpfr_get_z is now int instead of void. In practice, this
|
||||
should not break any existing code.
|
||||
- MPFR is now distributed under the GNU Lesser General Public License
|
||||
version 3 or later (LGPL v3+).
|
||||
- Rounding modes GMP_RNDx are now MPFR_RNDx (GMP_RNDx kept for
|
||||
compatibility).
|
||||
- A new rounding mode (MPFR_RNDA) is available to round away from zero.
|
||||
- The rounding mode type is now mpfr_rnd_t (as in previous versions,
|
||||
both mpfr_rnd_t and mp_rnd_t are accepted, but mp_rnd_t may be
|
||||
removed in the future).
|
||||
- The precision type is now mpfr_prec_t (as in previous versions, both
|
||||
mpfr_prec_t and mp_prec_t are accepted, but mp_prec_t may be removed
|
||||
in the future) and it is now signed (it was unsigned in MPFR 2.*, but
|
||||
this was not documented). In practice, this change should not affect
|
||||
existing code that assumed nothing on the precision type.
|
||||
- MPFR now has its own exponent type mpfr_exp_t, which is currently
|
||||
the same as GMP's mp_exp_t.
|
||||
- Functions mpfr_random and mpfr_random2 have been removed.
|
||||
- mpfr_get_f and mpfr_get_z now return a ternary value.
|
||||
- mpfr_strtofr now accepts bases from 37 to 62.
|
||||
- mpfr_custom_get_mantissa was renamed to mpfr_custom_get_significand
|
||||
(mpfr_custom_get_mantissa is still available via a #define).
|
||||
- Functions mpfr_get_si, mpfr_get_ui, mpfr_get_sj, mpfr_get_uj,
|
||||
mpfr_get_z and mpfr_get_z_2exp no longer have cases with undefined
|
||||
behavior; in these cases, the behavior is now specified, and in
|
||||
particular, the erange flag is set.
|
||||
- New functions mpfr_buildopt_tls_p and mpfr_buildopt_decimal_p giving
|
||||
information about options used at MPFR build time.
|
||||
- New function mpfr_regular_p.
|
||||
- New function mpfr_set_zero.
|
||||
- New function mpfr_digamma.
|
||||
- New function mpfr_ai (incomplete, experimental).
|
||||
- New functions mpfr_set_flt and mpfr_get_flt to convert from/to the
|
||||
float type.
|
||||
- New function mpfr_urandom.
|
||||
- New function mpfr_set_z_2exp (companion to mpfr_get_z_2exp, which
|
||||
was renamed from mpfr_get_z_exp in previous versions).
|
||||
- New function mpfr_min_prec.
|
||||
- Speed improvement for large precisions in the trigonometric functions
|
||||
(mpfr_sin, mpfr_cos, mpfr_tan, mpfr_sin_cos): speedup of about 2.5
|
||||
for 10^5 digits, of about 5 for 10^6 digits.
|
||||
- Speed improvement for large precisions of the inverse trigonometric
|
||||
functions (arcsin, arccos, arctan): about 2 for 10^3 digits, up to
|
||||
2.7 for 10^6 digits.
|
||||
- Some documentation files are installed in $docdir.
|
||||
- The detection of a GMP build directory (more precisely, the internal
|
||||
header files of GMP) was previously done separately from the use of
|
||||
the --with-gmp-build configure option. This was not consistent with
|
||||
the documentation and with other parts of the configure script. So,
|
||||
as of MPFR 3.0.0, the internal header files of GMP are now used if
|
||||
and only if the --with-gmp-build configure option is given.
|
||||
- The configure script recognizes some extra "long double" formats
|
||||
(double big endian, double little endian, double-double big endian).
|
||||
- MPFR manual: added "API Compatibility" section.
|
||||
- Test coverage: 97.1% lines of code.
|
||||
- Bug fixes.
|
||||
|
||||
Changes from versions 2.3.* to version 2.4.0:
|
||||
- The "andouillette sauce moutarde" release.
|
||||
- MPFR is now a GNU package.
|
||||
- Changes in the behavior of mpfr_strtofr and in its documentation
|
||||
concerning particular cases where the code and the documentation
|
||||
did not match; this change is also present in MPFR 2.3.1.
|
||||
- Behavior of mpfr_check_range changed: if the value is an inexact
|
||||
infinity, the overflow flag is set (in case it was lost); this
|
||||
change is also present in MPFR 2.3.2.
|
||||
- Function mpfr_init_gmp_rand (only defined when building MPFR without
|
||||
the --with-gmp-build configure option) is no longer defined at all.
|
||||
This function was private and not documented, and was used only in
|
||||
the MPFR test suite. User code that calls it is regarded as broken
|
||||
and may fail as a consequence. Running the old test suite against
|
||||
MPFR 2.4.0 may also fail.
|
||||
- New functions:
|
||||
* between a MPFR number and a double: mpfr_add_d, mpfr_sub_d,
|
||||
mpfr_d_sub, mpfr_mul_d, mpfr_div_d, mpfr_d_div,
|
||||
* formatted input/output:
|
||||
mpfr_printf, mpfr_fprintf, mpfr_vprintf, mpfr_vfprintf,
|
||||
mpfr_sprintf, mpfr_snprintf, mpfr_vsprintf, mpfr_vsnprintf,
|
||||
mpfr_asprintf, mpfr_vasprintf.
|
||||
* mpfr_sinh_cosh, mpfr_li2, mpfr_modf, mpfr_fmod, mpfr_rec_sqrt.
|
||||
- Configure test for TLS support.
|
||||
- Get default $CC and $CFLAGS from gmp.h (__GMP_CC / __GMP_CFLAGS,
|
||||
which are available as of GMP 4.2.3).
|
||||
- Documented the fact that mpfr_random and mpfr_random2 will be
|
||||
suppressed in the next release, and that the specification of
|
||||
mpfr_eq may change in the next release (for compatibility with
|
||||
the mpf layer of GMP).
|
||||
- Test coverage: 96.7% lines of code.
|
||||
- Bug fixes.
|
||||
|
||||
Changes from versions 2.2.* to version 2.3.0:
|
||||
- The mpfr.info file is now installed in the share subdirectory
|
||||
(as required by the Filesystem Hierarchy Standard); see output
|
||||
of "./configure --help".

|
||||
- Math functions are faster (both average and worst cases).
|
||||

- It is faster with low-precision floating point.
|
||||
- New global flag: ERANGE_FLAG.
|
||||
- Binary incompatible with previous versions, but API compatible.
|
||||
- mpfr_set_str doesn't allow anymore "@NAN@garbagechar" and "@INF@garbagechar",

|
||||
- function mpfr_isinteger renamed mpfr_integer_p.
|
||||
- return type of some functions changed from void to int, for consistency.
|
||||
- return type of mpfr_set_prec changed from int to void.
|
||||
- new values for exponent range.
|
||||
- rename internal variables.
|
||||
|
||||
Changes from version 2001 to version 2.0.1:
|
||||
- new mathematical functions: acos, acosh, asin, asinh, atan, atanh, cosh,
|
||||
base-2 exponential and logarithm, base-10 logarithm, expm1, factorial,

||||
pow, pow_si, pow_ui, sinh, tan, tanh, ui_pow, ui_pow_ui
|
||||

|
||||
mpfr_min, mpfr_max, mpfr_rint, mpfr_set_inf, mpfr_set_nan
|
||||

|
||||
- new predicates: mpfr_inf_p, mpfr_nan_p, mpfr_number_p, mpfr_isinteger,
|
||||
- add mechanism to set/check exponent range (overflow, underflow), partially
|
||||
implemented in the mpfr functions.
|
||||
- efficiency: mpfr_div is now faster when the divisor has a few limbs
|
||||
- rounding: now mpfr_pow implements exact rounding, and most functions return a
|
||||
ternary value indicating the position of the returned value wrt the exact one
|
||||
(thus the return value is now 'int' instead of 'void')
|
||||
- complete rewrite of the configuration files
|
||||
- mpfr_get_d, mpfr_{add,sub}_one_ulp now get a rounding mode as 2nd argument
|
||||
- some function names did change: mpz_set_fr is now mpfr_get_z_exp,
|
||||
mpfr_print_raw is now mpfr_print_binary.
|
||||
|
||||
Changes from version 1.0 to version 2001:
|
||||
- the default installation does not provide any more access to machine
|
||||
rounding mode, and as a consequence does not compare MPFR results with
|
||||
precision=53 to machine results. Add option -DTEST if you want to have
|
||||
access to machine rounding mode, and to check MPFR results against.
|
||||
- the MPFR files do not need <math.h> any more
|
||||
- the header file <mpfr.h> was split into <mpfr.h> for exported functions
|
||||
and <mpfr-impl.h> for internal functions. The user should not use functions
|
||||
or macros from <mpfr-impl.h>, since those may change in further releases.
|
||||
- <mpfr.h> was modified in order to make easy a C++ interface
|
||||
- MPFR now deals with infinities (+infinity and -infinity) and NaN
|
||||
- the missing function mpfr_swap is now available
|
||||
- mpfr_zeta was removed (was incomplete)
|
||||
- mpfr_init and mpfr_init2 now initialize the corresponding variable to 0
|
||||
(like in other initialization functions from GNU MP)
|
||||
- in case memory allocation fails, an error message is output
|
||||
- several bugs of version 1.0 were fixed
|
||||
|
||||
Changes from version 0.4 to version 1.0:
|
||||
|
||||
- Version 1.0 now uses a standard configure/make installation.
|
||||
- Version 1.0 implements all functions that are available in the MPF class
|
||||
from GMP 3.1 (except mpf_swap) and a header file mpf2mpfr.h is included in
|
||||
the distribution for easy change from MPF to MPFR.
|
||||
- Version 1.0 implements new elementary functions: mpfr_sincos
|
||||
- Some functions and macros have been renamed: mpfr_log2 is now
|
||||
mpfr_const_log2, mpfr_pi is now mpfr_const_pi, SIGN is now MPFR_SIGN.
|
||||
- Version 1.0 uses faster algorithms for mpfr_exp, mpfr_const_pi,
|
||||
mpfr_const_log2. Compare the timings from version 1.0 and version 0.4.
|
||||
- Version 1.0 corrects some bugs of version 0.4.
|
||||
- The precision of MPFR variables is now named mpfr_prec, which makes it
|
||||
easier to change it, to say unsigned long long. Same for the rounding mode
|
||||
which is called mp_rnd_t.
