Finally, any free program is threatened constantly by software

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.

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

patents cannot be used to render the program non-free.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains
|
TERMS AND CONDITIONS
|
||||||
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
|
0. Definitions.
|
||||||
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
|
"This License" refers to version 3 of the GNU General Public License.
|
||||||
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
|
"Copyright" also means copyright-like laws that apply to other kinds of

|
works, such as semiconductor masks.
|
||||||
|
|
||||||
2. You may modify your copy or copies of the Program or any portion
|
"The Program" refers to any copyrightable work licensed under this
|
||||||
of it, thus forming a work based on the Program, and copy and
|
License. Each licensee is addressed as "you". "Licensees" and
|
||||||
distribute such modifications or work under the terms of Section 1
|
"recipients" may be individuals or organizations.
|
||||||
above, provided that you also meet all of these conditions:
|
|
||||||
|
|
||||||
a) You must cause the modified files to carry prominent notices
|
To "modify" a work means to copy from or adapt all or part of the work
|
||||||
stating that you changed the files and the date of any change.
|
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.
|
||||||
|
|
||||||
b) You must cause any work that you distribute or publish, that in
|
A "covered work" means either the unmodified Program or a work based
|
||||||
whole or in part contains or is derived from the Program or any
|
on the Program.
|
||||||
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
|
To "propagate" a work means to do anything with it that, without
|
||||||
when run, you must cause it, when started running for such
|
permission, would make you directly or secondarily liable for
|
||||||
interactive use in the most ordinary way, to print or display an
|
infringement under applicable copyright law, except executing it on a
|
||||||
announcement including an appropriate copyright notice and a
|
computer or modifying a private copy. Propagation includes copying,
|
||||||
notice that there is no warranty (or else, saying that you provide
|
distribution (with or without modification), making available to the
|
||||||
a warranty) and that users may redistribute the program under
|
public, and in some countries other activities as well.
|
||||||
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
|
To "convey" a work means any kind of propagation that enables other
|
||||||
your rights to work written entirely by you; rather, the intent is to
|
parties to make or receive copies. Mere interaction with a user through
|
||||||
exercise the right to control the distribution of derivative or
|
a computer network, with no transfer of a copy, is not conveying.
|
||||||
collective works based on the Program.
|
|
||||||
|
|
||||||
In addition, mere aggregation of another work not based on the Program
|
An interactive user interface displays "Appropriate Legal Notices"
|
||||||
with the Program (or with a work based on the Program) on a volume of
|
to the extent that it includes a convenient and prominently visible
|
||||||
a storage or distribution medium does not bring the other work under
|
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.
|
||||||
|
|
||||||
3. You may copy and distribute the Program (or a work based on it,
|
1. Source Code.
|
||||||
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
|
The "source code" for a work means the preferred form of the work
|
||||||
source code, which must be distributed under the terms of Sections
|
for making modifications to it. "Object code" means any non-source
|
||||||
1 and 2 above on a medium customarily used for software interchange; or,
|
form of a work.
|
||||||
|
|
||||||
b) Accompany it with a written offer, valid for at least three
|
A "Standard Interface" means an interface that either is an official
|
||||||
years, to give any third party, for a charge no more than your
|
standard defined by a recognized standards body, or, in the case of
|
||||||
cost of physically performing source distribution, a complete

|

machine-readable copy of the corresponding source code, to be

is widely used among developers working in that language.

customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer
|
The "System Libraries" of an executable work include anything, other
|

to distribute corresponding source code. (This alternative is

than the work as a whole, that (a) is included in the normal form of

allowed only for noncommercial distribution and only if you

Component, and (b) serves only to enable use of the work with that

||||||
an offer, in accord with Subsection b above.)
|
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 source code for a work means the preferred form of the work for

The "Corresponding Source" for a work in object code form means all
|
||||||
making modifications to it. For an executable work, complete source

the source code needed to generate, install, and (for an executable
|
||||||
code means all the source code for all modules it contains, plus any
|
work) run the object code and to modify the work, including scripts to

associated interface definition files, plus the scripts used to
|
control those activities. However, it does not include the work's
|
||||||
control compilation and installation of the executable. However, as a

System Libraries, or general-purpose tools or generally available free
|
||||||
special exception, the source code distributed need not include
|
programs which are used unmodified in performing those activities but
|
||||||
anything that is normally distributed (in either source or binary
|
which are not part of the work. For example, Corresponding Source
|
||||||
form) with the major components (compiler, kernel, and so on) of the

subprograms and other parts of the work.

If distribution of executable or object code is made by offering

|
||||||
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
|
The Corresponding Source for a work in source code form is that
|
||||||
signed it. However, nothing else grants you permission to modify or
|
same work.
|
||||||
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
|
2. Basic Permissions.
|
||||||
Program), the recipient automatically receives a license from the
|
|
||||||
original licensor to copy, distribute or modify the Program subject to
|
All rights granted under this License are granted for the term of
|
||||||
these terms and conditions. You may not impose any further
|
copyright on the Program, and are irrevocable provided the stated
|
||||||
restrictions on the recipients' exercise of the rights granted herein.
|
conditions are met. This License explicitly affirms your unlimited
|
||||||
You are not responsible for enforcing compliance by third parties to
|
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.
|
this License.
|
||||||
|
|
||||||
7. If, as a consequence of a court judgment or allegation of patent
|
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||||
infringement or for any other reason (not limited to patent issues),
|
patent license under the contributor's essential patent claims, to
|
||||||
conditions are imposed on you (whether by court order, agreement or
|
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.

otherwise) that contradict the conditions of this License, they do not

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.

Ccollect backups data from local and remote hosts to your local harddisk.
|
||||||
|
Although ccollect creates full backups, it requires very less space on the backup medium, because ccollect uses hardlinks to create an initial copy of the last backup.
|
||||||
|
Only the inodes used by the hardlinks and the changed files need additional space.

[Almost complete Copy of an e-mail from Patrick Drolet]
|
||||||
|
|
||||||
|
Hello again,
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
I have created a script to better manage the backups since my
|
||||||
|
upload/download ratio and my bandwidth is limited by my ISP, and my hard
|
||||||
|
disk space is also somewhat limited. The script is called
|
||||||
|
"ccollect_mgr.sh".
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Provides the following features
|
||||||
|
|
||||||
|
1) Determine the interval (daily/weekly/monthly)
|
||||||
|
|
||||||
|
a. Define when you want weekly and monthly backups. It takes care of
|
||||||
|
the rest
|
||||||
|
|
||||||
|
2) Perform the backups using ccollect
|
||||||
|
|
||||||
|
3) Copy the ccollect log output to the first backup of the set
|
||||||
|
|
||||||
|
a. Keeping the detailed log of each backup is always handy!
|
||||||
|
|
||||||
|
4) Build a periodic report and include the real amount of disk used
|
||||||
|
|
||||||
|
a. Computes the real amount of disk used (eg: no double counting of
|
||||||
|
hard links)
|
||||||
|
|
||||||
|
b. Shows the actual amount of data transferred
|
||||||
|
|
||||||
|
5) Send an email if there has been errors or warnings
|
||||||
|
|
||||||
|
6) Send a periodic email to show transfer size, real backup size, etc
|
||||||
|
|
||||||
|
a. Weekly reports are nice.!
|
||||||
|
|
||||||
|
[...]
|
||||||
|
|
||||||
|
- rdu (real du), which computes the real amount of disk used (no
|
||||||
|
double/triple counting hard links), same code as in ccollect_mgr.sh.
|
||||||
|
|
||||||
|
- S60ccollect_example, an example script to put in etc/init.d to
|
||||||
|
add ccollect_mgr to the crontab

# This script was written primarily to gain better visibility of backups in
|
||||||
|
# an environment where data transfer is limited and so is bandwidth
|
||||||
|
# (eg: going through an ISP). The primary target of this script were a
|
||||||
|
# DNS323 and a QNAP T209 (eg: Busybox devices and not standard Linux devices)
|
||||||
|
# but it should run on any POSIX compliant device.
|
||||||
|
#
|
||||||
|
# Note: This is one of my first script in over a decade... don't use this as a
|
||||||
|
# reference (but take a look at ccollect.sh... very well written!)
|
||||||

# ----------------------------------------------------------------------------
|

#

|
# -------------------------------------------
|
||||||
|
# TO MAKE THIS SCRIPT RUN ON A BUSYBOX DEVICE
|
||||||
|
# -------------------------------------------
|
||||||
|
# - You may need to install Optware and the following packages:
|
||||||
|
# - findutils (to get a find utility which supports printf)
|
||||||
|
# - procps (to get a ps utility that is standard)
|
||||||
|
# - mini-sendmail (this is what I used to send emails... you could easily
|
||||||
|
# modify this to use sendmail, mutt, putmail, etc...).
|
||||||
|
# - On DNS323 only: Your Busybox is very limited. For details, see
|
||||||
|
# http://wiki.dns323.info/howto:ffp#shells. You need to redirect /bin/sh
|
||||||
|
# to the Busybox provided with ffp (Fun Plug). To do this, type:
|
||||||
|
# ln -fs /ffp/bin/sh /bin/sh
|
||||||
|
#
|
||||||
|
# --------------------------------------------------
|
||||||
|
# TO MAKE THIS SCRIPT RUN ON A STANDARD LINUX DEVICE
|
||||||
|
# --------------------------------------------------
|
||||||
|
# - You will need install mini_sendmail or rewrite the send_email routine.

||||||

Hello Nico,
|
||||||
|
|
||||||
|
I have attached three more patches for ccollect. Each patch
|
||||||
|
has comments explaining its motivation.
|
||||||
|
|
||||||
|
All of these patches work-for-me (but I continue to test
|
||||||
|
them). I would be interested in your opinion on, for example, the
|
||||||
|
general approach used in i.patch which changes the way options are
|
||||||
|
handled. I think it is a big improvement. If, however, you wanted
|
||||||
|
the code to go in a different direction, let me know before we
|
||||||
|
diverge too far.
|
||||||
|
|
||||||
|
Regards,
|
||||||
|
|
||||||
|
John

Dear Nico Schottelius,
|
||||||
|
|
||||||
|
I have started using ccollect and I very much like its design:
|
||||||
|
it is elegant and effective.
|
||||||
|
|
||||||
|
In the process of getting ccollect setup and running, I made
|
||||||
|
five changes, including one major new feature, that I hope you will
|
||||||
|
find useful.
|
||||||
|
|
||||||
|
First, I added the following before any old backup gets deleted:
|
||||||
|
|
||||||
|
> # Verify source is up and accepting connections before deleting any old backups
|
||||||
|
> rsync "$source" >/dev/null || _exit_err "Source ${source} is not readable. Skipping."
|
||||||
|
|
||||||
|
I think that this quick test is a much better than, say, pinging
|
||||||
|
the source in a pre-exec script: this tests not only that the
|
||||||
|
source is up and connected to the net, it also verifies (1) that
|
||||||
|
ssh is up and accepting our key (if we are using ssh), and (2) that
|
||||||
|
the source directory is mounted (if it needs to be mounted) and
|
||||||
|
readable.
|
||||||
|
|
||||||
|
Second, I found ccollect's use of ctime problematic. After
|
||||||
|
copying an old backup over to my ccollect destination, I adjusted
|
||||||
|
mtime and atime where needed using touch, e.g.:
|
||||||
|
|
||||||
|
touch -d"28 Apr 2009 3:00" destination/daily.01
|
||||||
|
|
||||||
|
However, as far as I know, there is no way to correct a bad ctime.
|
||||||
|
I ran into this issue repeatedly while adjusting my backup
|
||||||
|
configuration. (For example, "cp -a" preserves mtime but not
|
||||||
|
ctime. Even worse, "cp -al old new" also changes ctime on old.)
|
||||||
|
|
||||||
|
Another potential problem with ctime is that it is file-system
|
||||||
|
dependent: I have read that Windows sets ctime to create-time not
|
||||||
|
last change-time.
|
||||||
|
|
||||||
|
However, It is simple to give a new backup the correct mtime.
|
||||||
|
After the rsync step, I added the command:
|
||||||
|
|
||||||
|
553a616,617
|
||||||
|
> # Correct the modification time:
|
||||||
|
> pcmd touch "${destination_dir}"
|
||||||
|
|
||||||
|
Even if ccollect continues to use ctime for sorting, I see no
|
||||||
|
reason not to have the backup directory have the correct mtime.
|
||||||
|
|
||||||
|
To allow the rest of the code to use either ctime or mtime, I
|
||||||
|
added definitions:
|
||||||
|
|
||||||
|
44a45,47
|
||||||
|
> #TSORT="tc" ; NEWER="cnewer"
|
||||||
|
> TSORT="t" ; NEWER="newer"
|
||||||
|
|
||||||
|
(It would be better if this choice was user-configurable because
|
||||||
|
those with existing backup directories should continue to use ctime
|
||||||
|
until the mtimes of their directories are correct. The correction
|
||||||
|
would happen passively over time as new backups created using the
|
||||||
|
above touch command and the old ones are deleted.)
|
||||||
|
|
||||||
|
With these definitions, the proper link-dest directory can then be
|
||||||
|
found using this minor change (and comment update):
|
||||||
|
|
||||||
|
516,519c579,582
|
||||||
|
< # Use ls -1c instead of -1t, because last modification maybe the same on all
|
||||||
|
< # and metadate update (-c) is updated by rsync locally.
|
||||||
|
< #
|
||||||
|
< last_dir="$(pcmd ls -tcp1 "${ddir}" | grep '/$' | head -n 1)" || \
|
||||||
|
---
|
||||||
|
> # Depending on your file system, you may want to sort on:
|
||||||
|
> # 1. mtime (modification time) with TSORT=t, or
|
||||||
|
> # 2. ctime (last change time, usually) with TSORT=tc
|
||||||
|
> last_dir="$(pcmd ls -${TSORT}p1 "${ddir}" | grep '/$' | head -n 1)" || \
|
||||||
|
|
||||||
|
Thirdly, after I copied my old backups over to my ccollect
|
||||||
|
destination directory, I found that ccollect would delete a
|
||||||
|
recent backup not an old backup! My problem was that, unknown to
|
||||||
|
me, the algorithm to find the oldest backup (for deletion) was
|
||||||
|
inconsistent with that used to find the newest (for link-dest). I
|
||||||
|
suggest that these two should be consistent. Because time-sorting
|
||||||
|
seemed more consistent with the ccollect documentation, I suggest:
|
||||||
|
|
||||||
|
492,493c555,556
|
||||||
|
< pcmd ls -p1 "$ddir" | grep "^${INTERVAL}\..*/\$" | \
|
||||||
|
< sort -n | head -n "${remove}" > "${TMP}" || \
|
||||||
|
---
|
||||||
|
> pcmd ls -${TSORT}p1r "$ddir" | grep "^${INTERVAL}\..*/\$" | \
|
||||||
|
> head -n "${remove}" > "${TMP}" || \
|
||||||
|
|
||||||
|
Fourthly, in my experience, rsync error code 12 means complete
|
||||||
|
failure, usually because the source refuses the ssh connection.
|
||||||
|
So, I left the marker in that case:
|
||||||
|
|
||||||
|
558,559c622,625
|
||||||
|
< pcmd rm "${destination_dir}.${c_marker}" || \
|
||||||
|
< _exit_err "Removing ${destination_dir}/${c_marker} failed."
|
||||||
|
---
|
||||||
|
> if [ "$ret" -ne 12 ] ; then
|
||||||
|
> pcmd rm "${destination_dir}.${c_marker}" || \
|
||||||
|
> _exit_err "Removing ${destination_dir}/${c_marker} failed."
|
||||||
|
> fi
|
||||||
|
|
||||||
|
(A better solution might allow a user-configurable list of error
|
||||||
|
codes that are treated the same as a fail.)
|
||||||
|
|
||||||
|
Fifth, because I was frustrated by the problems of having a
|
||||||
|
cron-job decide which interval to backup, I added a major new
|
||||||
|
feature: the modified ccollect can now automatically select an
|
||||||
|
interval to use for backup.
|
||||||
|
|
||||||
|
Cron-job controlled backup works well if all machines are up and
|
||||||
|
running all the time and nothing ever goes wrong. I have, however,
|
||||||
|
some machines that are occasionally turned off, or that are mobile
|
||||||
|
and only sometimes connected to local net. For these machines, the
|
||||||
|
use of cron-jobs to select intervals can be a disaster.
|
||||||
|
|
||||||
|
There are several ways one could automatically choose an
|
||||||
|
appropriate interval. The method I show below has the advantage
|
||||||
|
that it works with existing ccollect configuration files. The only
|
||||||
|
requirement is that interval names be chosen to sort nicely (under
|
||||||
|
ls). For example, I currently use:
|
||||||
|
|
||||||
|
$ ls -1 intervals
|
||||||
|
a_daily
|
||||||
|
b_weekly
|
||||||
|
c_monthly
|
||||||
|
d_quarterly
|
||||||
|
e_yearly
|
||||||
|
$ cat intervals/*
|
||||||
|
6
|
||||||
|
3
|
||||||
|
2
|
||||||
|
3
|
||||||
|
30
|
||||||
|
|
||||||
|
A simpler example would be:
|
||||||
|
|
||||||
|
$ ls -1 intervals
|
||||||
|
int1
|
||||||
|
int2
|
||||||
|
int3
|
||||||
|
$ cat intervals/*
|
||||||
|
2
|
||||||
|
3
|
||||||
|
4
|
||||||
|
|
||||||
|
The algorithm works as follows:
|
||||||
|
|
||||||
|
If no backup exists for the least frequent interval (int3 in the
|
||||||
|
simpler example), then use that interval. Otherwise, use the
|
||||||
|
most frequent interval (int1) unless there are "$(cat
|
||||||
|
intervals/int1)" int1 backups more recent than any int2 or int3
|
||||||
|
backup, in which case select int2 unless there are "$(cat
|
||||||
|
intervals/int2)" int2 backups more recent than any int3 backups
|
||||||
|
in which case choose int3.
|
||||||
|
|
||||||
|
This algorithm works well cycling through all the backups for my
|
||||||
|
always connected machines as well as for my usually connected
|
||||||
|
machines, and rarely connected machines. (For a rarely connected
|
||||||
|
machine, interval names like "b_weekly" lose their English meaning
|
||||||
|
but it still does a reasonable job of rotating through the
|
||||||
|
intervals.)
|
||||||
|
|
||||||
|
In addition to being more robust, the automatic interval
|
||||||
|
selection means that crontab is greatly simplified: only one line
|
||||||
|
is needed. I use:
|
||||||
|
|
||||||
|
30 3 * * * ccollect.sh AUTO host1 host2 host3 | tee -a /var/log/ccollect-full.log | ccollect_analyse_logs.sh iwe
|
||||||
|
|
||||||
|
Some users might prefer a calendar-driven algorithm such as: do
|
||||||
|
a yearly backup the first time a machine is connected during a new
|
||||||
|
year; do a monthly backup the first that a machine is connected
|
||||||
|
during a month; etc. This, however, would require a change to the
|
||||||
|
ccollect configuration files. So, I didn't pursue the idea any
|
||||||
|
further.
|
||||||
|
|
||||||
|
The code checks to see if the user specified the interval as
|
||||||
|
AUTO. If so, the auto_interval function is called to select the
|
||||||
|
interval:
|
||||||
|
|
||||||
|
347a417,420
|
||||||
|
> if [ ${INTERVAL} = "AUTO" ] ; then
|
||||||
|
> auto_interval
|
||||||
|
> _techo "Selected interval: '$INTERVAL'"
|
||||||
|
> fi
|
||||||
|
|
||||||
|
The code for auto_interval is as follows (note that it allows 'more
|
||||||
|
recent' to be defined by either ctime or mtime as per the TSORT
|
||||||
|
variable):
|
||||||

While I consider the auto_interval code to be developmental, I have
|
||||||
|
been using it for my nightly backups and it works for me.
|
||||||
|
|
||||||
|
One last change: For auto_interval to work, it needs "ddir" to
|
||||||
|
be defined first. Consequently, I had to move the following code
|
||||||
|
so it gets run before auto_interval is called:
|
||||||
|
|
||||||
|
369,380c442,443

I have some other ideas but this is all I have implemented at
|
||||||
|
the moment. Files are attached.

|
||||||
|
think.

Hello Hacker,
|
||||||
|
|
||||||
|
I really appreciate your interest in hacking this software, but
|
||||||
|
I am kind of critical when seeing patches. Thus I created this
|
||||||
|
file to give you some hints of my thinking quirks.
|
||||||
|
|
||||||
|
|
||||||
|
Submitting patches
|
||||||
|
------------------
|
||||||
|
Make my life easier, make your life easier, use a version control system (vcs).
|
||||||
|
For this software the preferred vcs is git. Clone the latest repo, create
|
||||||
|
a new local branch (git checkout -b <branchname>) write down your ideas.
|
||||||
|
|
||||||
|
When you're done, push all your stuff out to some public repo and drop a
|
||||||
|
mail to the mailinglist, what you did and where to get it.
|
||||||
|
|
||||||
|
|
||||||
|
Introduce a feature or change behaviour
|
||||||
|
---------------------------------------
|
||||||
|
Uhh, fancy! You have had a great idea, then it's time to change
|
||||||
|
the major version, so others know that something changed.
|
||||||
|
|
||||||
|
If the configuration format is changed, add a script to tools/
|
||||||
|
to allow users upgrade their configuration to this major version.
|
||||||
|
|
||||||
|
And now comes the most difficult part: Add documentation. Nobody
|
||||||
|
benefits from your cool feature, if it is not known. I know, writing
|
||||||
|
documentation is not so much fun, but you also expect good documentation
|
||||||
|
for this software, don't you?
|
||||||
|
|
||||||
|
|
||||||
|
If you think my thinking quirks must be corrected
|
||||||
|
-------------------------------------------------
|
||||||
|
See above ("Submitting patches") and submit a patch to this file.
|
||||||
|
|
||||||
|
|
||||||
|
Thanks for reading.
