* Provide __size_t via <sys/_types.h>Sebastian Huber2016-04-152-2/+17
| | | | | | | | | | | | | | | | | | | | | Various FreeBSD source and header files need a typedef __size_t via <sys/_types.h>. Unfortunately the GCC provided <stddef.h> uses #if (defined (__FreeBSD__) && (__FreeBSD__ >= 5)) \ || defined(__DragonFly__) \ || defined(__FreeBSD_kernel__) /* __size_t is a typedef on FreeBSD 5, must not trash it. */ #elif defined (__VMS__) /* __size_t is also a typedef on VMS. */ #else #define __size_t #endif and therefore defines __size_t on Newlib targets which would trash a __size_t typedef. Include <stddef.h> before <sys/_types.h> in <sys/types.h> and undefine __size_t in <sys/_types.h> as a workaround. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

* Use __machine_*_t_defined for internal typesSebastian Huber2016-04-156-49/+49
| | | | | | | | | | | | | | | | | | | | | | Newlib defines defaults for internal types via <sys/_types.h> and uses <machine/_types.h> to let targets define their own type if necessary. Previously for example #ifndef __dev_t_defined typedef short __dev_t; #endif However, the __*_t_defined pattern conflicts with the glibc type guard pattern for user types, e.g. dev_t in this example. Introduce a __machine_*_t_defined pattern for internal types (defined by <machine/_types.h>, used by <sys/_types.h>). For example #ifndef __machine_dev_t_defined typedef short __dev_t; #endif Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* Feature test macros overhaul: string.h and strings.h overlapsYaakov Selkowitz2016-04-132-7/+12
| | | | | | | | | | | strings.h is the header mandated for these functions in POSIX.1 prior to 2008 (when most of these were removed). The declarations in string.h are only for BSD compatibility.

* Eliminate use of Newlib-specific <machine/types.h>Sebastian Huber2016-04-1314-46/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change solves a glibc/BSD compatibility problem. glibc and BSD use double underscore types for internal types. The Linux port of Newlib uses some glibc provided internal type definitions which are not protected by guard defines, e.g. __off_t. To avoid a conflict Newlib uses single underscore types for some internal types, e.g. _off_t. However, for BSD compatibility we have to define the internal types with double underscore names in <sys/_types.h>. The header file <machine/types.h> is Newlib-specific. It was used instead of <sys/_types.h> to provide the internal type definitions _CLOCK_T, _TIME_T_, _CLOCKID_T_, _TIMER_T_, and __suseconds_t. Move these definitions to <sys/_types.h> (there exist two instances of this file, one for Linux and one for all other targets). This makes the _HAVE_SYSTYPES configuration define obsolete (could possibly break the __RDOS__ target). Use the standard <sys/_types.h> include throughout. Move __loff_t defintion to default (non-Linux) <sys/_types.h>. Define it via _off64_t to avoid a dependency on the compiler. Provide the __off_t definition via default (non-Linux) <sys/_types.h> based on _off_t for all systems except Cygwin. For Cygwin use _off64_t. Define off_t via __off_t. Provide the __pid_t definition via default (non-Linux) <sys/_types.h>. This prevents a potential __pid_t and pid_t incompatibility. Add BSD guard defines for pid_t.

* strxfrm/wcsxfrm: Always return length of the transformed stringCorinna Vinschen2016-04-121-12/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | Cygwin's strxfrm/wcsfrm treated a too short output buffer as an error condition and always returned the size value provided as third parameter. This is not as it's documented in POSIX.1-2008. Rather, the only error condition is an invalid input string(*). Other than that, the functions are supposed to return the length of the resulting sort key, even if the output buffer is too small. In the latter case the content of the output array is unspecified, but it's the job of the application to check that the return value is greater or equal to the provided buffer size. (*) We have to make an exception in Cygwin: strxfrm has to call the UNICODE function LCMapStringW for reasons outlined in a source comment. If the incoming multibyte string is so large that we fail to malloc the space required to convert it to a wchar_t string, we have to ser errno as well since we have nothing to call LCMapStringW with. * nlsfuncs.cc (wcsxfrm): Fix expression computing offset of trailing wchar_t NUL. Compute correct return value even if output buffer is too small. (strxfrm): Handle failing malloc. Compute correct return value even if output buffer is too small.

* Be truthful about reporting whether readahead is availableJohannes Schindelin2016-04-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In 7346568 (Make requested console reports work, 2016-03-16), code was introduced to report the current cursor position. It works by using a pointer that either points to the next byte in the readahead buffer, or to a NUL byte if the buffer is depleted, or the pointer is NULL. These conditions are heeded in the fhandler_console::read() method, but the condition that the pointer can point at the end of the readahead buffer was not handled properly in the get_cons_readahead_valid() method. This poses a problem e.g. in Git for Windows (which uses a slightly modified MSYS2 runtime which is in turn a slightly modified Cygwin runtime) when vim queries the cursor position and immediately goes on to read console input, erroneously thinking that the readahead buffer is valid when it is already depleted instead. This condition results in an apparent freeze that can be helped only by pressing keys repeatedly. The full Git for Windows bug report is here: https://github.com/git-for-windows/git/issues/711 Let's just teach the get_cons_readahead_valid() method to handle a depleted readahead buffer correctly.

* Rename without-mingw-progs to with-cross-bootstrapPeter Foley2016-04-046-18/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename without-mingw-progs to with-cross-bootstrap, since it now disables additional checks that are problematic for cross-compilers. When cross-compiling a toolchain targeting cygwin, building cygwin1.dll requires libgcc. However, building libgcc requires the cygwin headers to be installed. Configuring cygwin requries the mingw-crt libraries, which require the cygwin headers to be installed. Work around this circular dependency by making the --with-cross-bootstrap configure option skip cygwin's configure checks for valid mingw-crt libraries. Cygwin will still properly link against these libraries if they exist, but this allows configure to succeed even if the libraries have not been built yet. Since the mingw-crt libraries only require the cygwin headers to be installed, this allows us to successfully configure cygwin so that we can only install the headers without trying to build any libraries. winsup/ChangeLog configure.ac: rename without-mingw-progs option to with-cross-bootstrap configure: regenerate winsup/cygserver/ChangeLog configure.ac: don't check AC_WINDOWS_LIBS when using with-cross-bootstrap configure: regenerate winsup/cygwin/ChangeLog configure.ac: don't check AC_WINDOWS_LIBS when using with-cross-bootstrap configure: regenerate Signed-off-by: Peter Foley <pefoley2@pefoley.com>
