This patch converts the tst-signal-numbers test from shell + awk to Python. As with gen-as-const, the point is not so much that shell and awk are problematic for this code, as that it's useful to build up general infrastructure in Python for use of a range of code involving extracting values from C headers. This patch moves some code from gen-as-const.py to a new glibcextract.py, which also gains functions relating to listing macros, and comparing the values of a set of macros from compiling two different pieces of code. It's not just signal numbers that should have such tests; pretty much any case where glibc copies constants from Linux kernel headers should have such tests that the values and sets of constants agree except where differences are known to be OK. Much the same also applies to structure layouts (although testing those without hardcoding lists of fields to test will be more complicated). Given this patch, another test for a set of macros would essentially be just a call to glibcextract.compare_macro_consts (plus boilerplate code - and we could move to having separate text files defining such tests, like the .sym inputs to gen-as-const, so that only a single Python script is needed for most such tests). Some such tests would of course need new features, e.g. where the set of macros changes in new kernel versions (so you need to allow new macro names on the kernel side if the kernel headers are newer than the version known to glibc, and extra macros on the glibc side if the kernel headers are older). tst-syscall-list.sh could become a Python script that uses common code to generate lists of macros but does other things with its own custom logic. There are a few differences from the existing shell + awk test. Because the new test evaluates constants using the compiler, no special handling is needed any more for one signal name being defined to another. Because asm/signal.h now needs to pass through the compiler, not just the preprocessor, stddef.h is included as well (given the asm/signal.h issue that it requires an externally provided definition of size_t). The previous code defined __ASSEMBLER__ with asm/signal.h; this is removed (__ASSEMBLY__, a different macro, eliminates the requirement for stddef.h on some but not all architectures). Tested for x86_64, and with build-many-glibcs.py. * scripts/glibcextract.py: New file. * scripts/gen-as-const.py: Do not import os.path, re, subprocess or tempfile. Import glibcexctract. (compute_c_consts): Remove. Moved to glibcextract.py. (gen_test): Update reference to compute_c_consts. (main): Likewise. * sysdeps/unix/sysv/linux/tst-signal-numbers.py: New file. * sysdeps/unix/sysv/linux/tst-signal-numbers.sh: Remove. * sysdeps/unix/sysv/linux/Makefile ($(objpfx)tst-signal-numbers.out): Use tst-signal-numbers.py. Redirect stderr as well as stdout. |

This directory contains the sources of the GNU C Library. See the file "version.h" for what release version you have. The GNU C Library is the standard system C library for all GNU systems, and is an important part of what makes up a GNU system. It provides the system API for all programs written in C and C-compatible languages such as C++ and Objective C; the runtime facilities of other programming languages use the C library to access the underlying operating system. In GNU/Linux systems, the C library works with the Linux kernel to implement the operating system behavior seen by user applications. In GNU/Hurd systems, it works with a microkernel and Hurd servers. The GNU C Library implements much of the POSIX.1 functionality in the GNU/Hurd system, using configurations i[4567]86-*-gnu. When working with Linux kernels, this version of the GNU C Library requires Linux kernel version 3.2 or later. Also note that the shared version of the libgcc_s library must be installed for the pthread library to work correctly. The GNU C Library supports these configurations for using Linux kernels: aarch64*-*-linux-gnu alpha*-*-linux-gnu arm-*-linux-gnueabi hppa-*-linux-gnu i[4567]86-*-linux-gnu x86_64-*-linux-gnu Can build either x86_64 or x32 ia64-*-linux-gnu m68k-*-linux-gnu microblaze*-*-linux-gnu mips-*-linux-gnu mips64-*-linux-gnu powerpc-*-linux-gnu Hardware or software floating point, BE only. powerpc64*-*-linux-gnu Big-endian and little-endian. s390-*-linux-gnu s390x-*-linux-gnu riscv64-*-linux-gnu sh[34]-*-linux-gnu sparc*-*-linux-gnu sparc64*-*-linux-gnu If you are interested in doing a port, please contact the glibc maintainers; see http://www.gnu.org/software/libc/ for more information. See the file INSTALL to find out how to configure, build, and install the GNU C Library. You might also consider reading the WWW pages for the C library at http://www.gnu.org/software/libc/. The GNU C Library is (almost) completely documented by the Texinfo manual found in the `manual/' subdirectory. The manual is still being updated and contains some known errors and omissions; we regret that we do not have the resources to work on the manual as much as we would like. For corrections to the manual, please file a bug in the `manual' component, following the bug-reporting instructions below. Please be sure to check the manual in the current development sources to see if your problem has already been corrected. Please see http://www.gnu.org/software/libc/bugs.html for bug reporting information. We are now using the Bugzilla system to track all bug reports. This web page gives detailed information on how to report bugs properly. The GNU C Library is free software. See the file COPYING.LIB for copying conditions, and LICENSES for notices about a few contributions that require these additional notices to be distributed. License copyright years may be listed using range notation, e.g., 1996-2015, indicating that every year in the range, inclusive, is a copyrightable year that would otherwise be listed individually.
