assert.h: allow gcc to detect assert(a = 1) errors

2016-12-18T09:30:51Z

* assert/assert.h (assert): Rewrite assert's definition so that a s/==/=/ typo, e.g., assert(errno = ENOENT) is not hidden from gcc's -Wparentheses by assert-added parentheses. The new definition uses "if (expr) /* empty */; else __assert_fail...", so gcc -Wall will now detect that type of error in an assert, too. The __STRICT_ANSI__ disjunct is to make this work also with both -ansi and -pedantic, which would reject the use of ({...}). I would have preferred to use __extension__ to mark that, but doing so would mistakenly suppress warnings about any extension in the user-supplied "expr". E.g., "assert ( ({1;}) )" must continue to evoke a warning.

Remove redundant C locale settings.

2014-06-07T19:58:36Z

Various glibc build / install / test code has C locale settings that are redundant with LC_ALL=C. LC_ALL takes precedence over LANG, so anywhere that sets LC_ALL=C (explicitly, or through it being in the default environment for running tests) does not need to set LANG=C. LC_ALL=C also takes precedence over LANGUAGE, since 2001-01-02 Ulrich Drepper * intl/dcigettext.c (guess_category_value): Rewrite so that LANGUAGE value is ignored if the selected locale is the C locale. * intl/tst-gettext.c: Set locale for above change. * intl/tst-translit.c: Likewise. and so settings of LANGUAGE=C are also redundant when LC_ALL=C is set. One test also had LC_ALL=C in its -ENV setting, although it's part of the default environment used for tests. This patch removes the redundant settings. It removes a suggestion in install.texi of setting LANGUAGE=C LC_ALL=C for "make install"; the Makefile.in target "install" already sets LC_ALL_C so there's no need for the user to set it (and nor should there be any need for the user to set it). If some build machine tool used by "make install" uses a version of libintl predating that 2001 change, and the user has LANGUAGE set, the removal of LANGUAGE=C from the Makefile.in "install" rule could in principle affect the user's installation. However, I don't think we need to be concerned about pre-2001 build tools. Tested x86_64. * Makefile (install): Don't set LANGUAGE. * Makefile.in (install): Likewise. * assert/Makefile (test-assert-ENV): Remove variable. (test-assert-perr-ENV): Likewise. * elf/Makefile (neededtest4-ENV): Likewise. * iconvdata/Makefile ($(inst_gconvdir)/gconv-modules) [$(cross-compiling) = no]: Don't set LANGUAGE. * io/ftwtest-sh (LANG): Remove variable. * libio/Makefile (tst-widetext-ENV): Likewise. * manual/install.texi (Running make install): Don't refer to environment settings for make install. * INSTALL: Regenerated. * nptl/tst-tls6.sh: Don't set LANG. * posix/globtest.sh (LANG): Remove variable. * string/Makefile (tester-ENV): Likewise. (inl-tester-ENV): Likewise. (noinl-tester-ENV): Likewise. * sysdeps/s390/s390-64/Makefile ($(inst_gconvdir)/gconv-modules) [$(cross-compiling) = no]: Don't set LANGUAGE. * timezone/Makefile (build-testdata): Use $(built-program-cmd) without explicit environment settings. localedata/ChangeLog: * tst-fmon.sh: Don't set LANGUAGE. * tst-locale.sh: Likewise.

Consistently include Makeconfig after defining subdir.

2014-02-26T23:12:03Z

In I noted it was necessary to add includes of Makeconfig early in various subdirectory makefiles for the tests-special variable settings added by that patch to be conditional on configuration information. No-one commented on the general question there of whether Makeconfig should always be included immediately after the definition of subdir. This patch implements that early inclusion of Makeconfig in each directory (which is a lot easier than consistent placement of includes of Rules). Includes are added if needed, or moved up if already present. Subdirectory "all:" targets are removed, since Makeconfig provides one. There is potential for further cleanups I haven't done. Rules and Makerules have code such as ifneq "$(findstring env,$(origin headers))" "" headers := endif to override to empty any value of various variables that came from the environment. I think there is a case for Makeconfig setting all the subdirectory variables (other than subdir) to empty to ensure no outside value is going to take effect if a subdirectory fails to define a variable. (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.) Rules and Makerules would give errors if Makeconfig hadn't already been included, instead of including it themselves. The special code to override values coming from the environment would then be obsolete and could be removed.
