The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple '-arch' options to the compiler but only a single '-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases. You may have to build one architecture at a time and combine the results using the 'lipo' tool if you have problems. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. For packages that use the GNU libiconv library, you can use the `configure' option `--with-libiconv-prefix' to specify the prefix you used while installing libiconv. Particular Systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae" and if that doesn't work, install pre-built binaries of GCC for HP-UX. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On AIX 3, the C include files by default don't define some necessary prototype declarations. If GNU CC is not installed, it is recommended to use the following options: ./configure CC="xlc -D_ALL_SOURCE" On BeOS, user installed software goes in /boot/home/config, not /usr/local. It is recommended to use the following options: ./configure --prefix=/boot/home/config Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR.

But we also need to distinguish (with a reasonable confidence) a stack overflow from a regular SIGSEGV. If we have A) and B), we use the Heuristic AB: If the fault address is near the stack pointer, it's a stack overflow.

This heuristic comes in two flavours: On OSes which let the stack's VMA grow continuously, we determine the bottom by use of getrlimit(). On OSes which preallocate the stack's VMA with its maximum size (like BeOS), we use the stack's VMA directly. */ /* Note: Solaris 11 defines a function 'stack_violation' .

Actually, it's even more complicated: The stack has the following layout: | |guard|----------stack-----------| and when the guard page is touched, the system maps it PAGE_READWRITE and allocates a new guard page below it: | |guard|-------------stack--------------| Only when no new guard page can be allocated (because the maximum stack size has been reached), will we see an exception. |guard|-------------------------stack--------------------------| Second, we must reinstall the guard page. Otherwise, on the next stack overflow, the application will simply crash (on WinNT: silently, on Win95: with an error message box and freezing the system).

It interprets a flavor VM_REGION_BASIC_INFO as VM_REGION_BASIC_INFO_64, which is dangerous since 'struct vm_region_basic_info_64' is larger than 'struct vm_region_basic_info'; therefore let's write VM_REGION_BASIC_INFO_64 explicitly. - mach_vm_region.

A page fault occurs when a program tries to access to a region of memory that is currently not available. Catching and handling a page fault is a useful technique for implementing: - pageable virtual memory, - memory-mapped access to persistent databases, - generational garbage collectors, - stack overflow handlers, - distributed shared memory, - ... This library supports three sets of functions, all defined in : - Global SIGSEGV handlers: sigsegv_install_handler, sigsegv_deinstall_handler. - Local SIGSEGV handlers (a handler per memory area): sigsegv_init, sigsegv_register, sigsegv_unregister, sigsegv_dispatch. - Stack overflow handlers: stackoverflow_install_handler, stackoverflow_deinstall_handler. Each of the three APIs can be used independently or simultaneously. For examples of the use of the APIs, see: - Global SIGSEGV handlers: see tests/test-catch-segv1.c. - Local SIGSEGV handlers: see tests/test-segv-dispatcher1.c. - Stack overflow handlers: see tests/test-catch-stackoverflow1.c. About portability. Some platforms don't support this functionality. In , the preprocessor macro HAVE_SIGSEGV_RECOVERY will be defined if global and local SIGSEGV handlers are available, and the preprocessor macro HAVE_STACK_OVERFLOW_RECOVERY will be defined if stack overflow handlers are available. Note that the declared functions are available in all cases; on platforms where HAVE_SIGSEGV_RECOVERY or HAVE_STACK_OVERFLOW_RECOVERY is not defined, they will simply always return an error code or do nothing. The list of platforms where this library is known to work is contained in the file PORTING. About pageable virtual memory. Pageable virtual memory is usually done in the operating system's kernel. This library helps in implementing the others. Installing a page fault handler is usually more efficient than doing access checks in software at every access, because it's effectively the hardware (the MMU) which checks whether a page is present or not. Note that if you use system calls (like read()) to write into write- protected pages, the system will react by returning -1 and setting errno to EFAULT, instead of signalling SIGSEGV and restarting the system call. In this case, the program has to do what the SIGSEGV handler would do, and then restart the read() operation. Some buggy systems (SunOS 4) go into an endless loop on this occasion; on these systems you have to make sure that an area is writable _before_ you call read() on it, About stack overflow handlers. In some applications, the stack overflow handler performs some cleanup or notifies the user and then immediately terminates the application. In other applications, the stack overflow handler longjmps back to a central point in the application. This library supports both uses. In the second case, the handler must ensure to restore the normal signal mask (because many signals are blocked while the handler is executed), and must also call sigsegv_leave_handler() to transfer control; then only it can longjmp away. Note that longjmping back to a central point in the application can leave the application in an inconsistent state, because 1) no cleanup is executed for call frames that are being unwound, 2) the code being executed while the stack overflow occurred might leave data structures in an intermediate, inconsistent state. If you want to avoid the first problem, you need to restructure your application into three or more threads: - a main thread, which creates the other threads, - worker threads, which may cause stack overflows, and in which all cleanups are registered through the pthread_cleanup_push function, - a handler thread, which contains the handler for stack overflow and other kinds of SIGSEGV. The handler will call pthread_cancel on the worker thread whose stack overflowed. You will need to use the function pthread_sigmask on all threads except the handler thread, in order to ensure that the SIGSEGV signal gets handled in the designated handler thread. If you want to avoid the second problem together with the first problem, you need to enclose code that manipulates data structures in a way that is not safe to be interrupted within calls to pthread_setcancelstate() or pthread_setcanceltype(). If you want to avoid just the second problem, you need to manipulate all data structures in a way that is safe to be interrupted at any moment and also compile your program with the gcc flag -fnon-call-exceptions. About shared libraries. This library builds as a static library by default. This seems useful because of the small size of the library (4 KB). Of course, you can build it as a shared library by specifying the configure option '--enable-shared'.

For this, you need to install * Cygwin (from https://cygwin.com/), * some packages available from the Cygwin package installer: make * the mingw cross-compilation tools and runtime package, available from the Cygwin package installer (setup-x86_64.exe): - for creating 32-bit binaries: packages mingw64-i686-gcc-core, mingw64-i686-headers, mingw64-i686-runtime - for creating 64-bit binaries: packages mingw64-x86_64-gcc-core, mingw64-x86_64-headers, mingw64-x86_64-runtime Building 32-bit binaries for mingw is achieved through the following preparation, configure, and build commands: PATH=/usr/local/mingw32/bin:$PATH export PATH ./configure --host=i686-w64-mingw32 --prefix=/usr/local/mingw32 \ CC=i686-w64-mingw32-gcc \ CPPFLAGS="-I/usr/local/mingw32/include -Wall" \ LDFLAGS="-L/usr/local/mingw32/lib" make make check Building 64-bit binaries for mingw is achieved through the following preparation, configure, and build commands: PATH=/usr/local/mingw64/bin:$PATH export PATH ./configure --host=x86_64-w64-mingw32 --prefix=/usr/local/mingw64 \ CC=x86_64-w64-mingw32-gcc \ CPPFLAGS="-I/usr/local/mingw64/include -Wall" \ LDFLAGS="-L/usr/local/mingw64/lib" make make check Installation: make install =============================================================================== 2) Native binaries, built using the MS Visual C/C++ tool chain. Note that binaries created with MSVC have a distribution constraint: They depend on a closed-source library ('msvcr90.dll' for MSVC 9.0, 'vcruntime140.dll' for MSVC 14.0, and so on) which is not normally part of a Windows installation. You cannot distribute 'vcruntime*.dll' with the binaries - this would be a violation of the GPL and of the Microsoft EULA. You can distribute the binaries without including 'vcruntime*.dll'. Users who don't have this library on their system will require to pull some files (api-ms-win*.dll) through the Windows Update mechanism, see https://support.microsoft.com/en-us/kb/2999226 . This recipe requires MS Visual C/C++ 9.0 or newer. You don't need the Visual Studio IDE, just the C/C++ tool chain. As of 2016, you can install the MS Visual C/C++ 14.0 tool chain from http://landinghub.visualstudio.com/visual-cpp-build-tools (it's the file visualcppbuildtools_full.exe). This recipe requires also a Cygwin environment (with 'bash', the common POSIX commands, and 'make') as a build environment. Building with 'nmake' is not supported. For this, you need to install * Cygwin (from https://cygwin.com/), * some packages available from the Cygwin package installer: make You also need the scripts 'ar-lib' and 'compile' from https://git.savannah.gnu.org/gitweb/?p=automake.git;a=blob_plain;f=lib/ar-lib;hb=HEAD https://git.savannah.gnu.org/gitweb/?p=automake.git;a=blob_plain;f=lib/compile;hb=HEAD respectively. They may also be included in this package, in directory 'build-aux/'. Save them; the instructions below assume that you stored them in $HOME/msvc/. Make them executable: chmod a+x ar-lib compile Start a bash (from Cygwin). Make sure that the MSVC tools ("cl" etc.) are found in PATH and the environment variables INCLUDE and LIB are set appropriately. In a typical MSVC 9.0 installation, it can be achieved by running C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\vsvars32.bat In a typical MSVC 14.0 installation on Windows 10, it can be achieved - for creating 32-bit binaries: through the following bash commands: # Set environment variables for using MSVC 14, # for creating native 32-bit Windows executables. # Windows C library headers and libraries.

mounted. (It is not mounted by default.) Porting to new platforms ======================== On Unix systems, where faults are notified to the program through a signal handler, the core routines in handler-unix.c can be used without modifications. But they need the following bits of information. Each of them is stored in a platform dependent file; the file is chosen in configure. * List of signals that are sent when an invalid virtual memory address is accessed, or when the stack overflows. This is a file among signals-*.h. configure chooses and sets the variable CFG_SIGNALS. * What arguments are passed to a fault handler. This is a file among fault-*.h. configure chooses and sets the variable CFG_FAULT. * How to determine the stack's virtual memory area. This is a file among stackvma-*.c. configure chooses and sets the variable CFG_STACKVMA. * How to leave a signal handler that is executing on the alternate signal stack. This is a file among leave-*.c. configure chooses and sets the variable CFG_LEAVE. For each of these, the approach should be: - Find a way to implement the needed functionality. This might involve study of the system include files (in particular and ) and of the kernel sources. For CFG_FAULT, the best starting point is to run the tests/sigsegv1 program with a breakpoint set at 'sigsegv_handler'. - Add to configure.ac a test whether your new code works. This will help portability to platforms similar to yours. Then regenerate the configure script (run "autoconf") and verify that the test says "yes" on your platform. - Create a platform dependent file (e.g. fault--.h) and change configure.ac to choose this particular file when your test says "yes". Then regenerate the configure script (run "autoconf"). - Specifically for CFG_FAULT: - Use './configure --disable-stackvma'. This makes sure that the stackoverflow* tests use the SIGSEGV_FAULT_STACKPOINTER macro and not some other heuristic. - For Linux platforms, search for definitions of 'setup_frame' and 'setup_rt_frame' functions in the kernel source code. - For FreeBSD platforms, search for definitions of 'sendsig' functions in the kernel source code. - Verify that "make" and "make check" pass. For non-Unix systems, a separate handler-.c is likely to be needed. libsigsegv-2.14/config.h.in0000664000000000000000000001114514166077013014330 0ustar rootroot/* config.h.in.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision 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, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This 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 Library General Public License instead of this License.
