One wart in the original support for test wrappers for cross testing, as noted in <https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the requirement for test wrappers to pass a poorly-defined set of environment variables from the build system to the system running the glibc under test. Although some variables are passed explicitly via $(test-wrapper-env), including LD_* variables that simply can't be passed implicitly because of the side effects they'd have on the build system's dynamic linker, others are passed implicitly, including variables such as GCONV_PATH and LOCPATH that could potentially affect the build system's libc (so effectively relying on any such effects not breaking the wrappers). In addition, the code in cross-test-ssh.sh for preserving environment variables is fragile (it depends on how bash formats a list of exported variables, and could well break for multi-line variable definitions where the contents contain things looking like other variable definitions). This patch moves to explicitly passing environment variables via $(test-wrapper-env). Makefile variables that previously used $(test-wrapper) are split up into -before-env and -after-env parts that can be passed separately to the various .sh files used in testing, so those files can then insert environment settings between the two parts. The common default environment settings in make-test-out are made into a separate makefile variable that can also be passed to scripts, rather than many scripts duplicating those settings (for testing an installed glibc, it is desirable to have the GCONV_PATH setting on just one place, so just that one place needs to support it pointing to an installed sysroot instead of the build tree). The default settings are included in the variables such as $(test-program-prefix), so that if tests do not need any non-default settings they can continue to use single variables rather than the split-up variables. Although this patch cleans up LC_ALL=C settings (that being part of the common defaults), various LANG=C and LANGUAGE=C settings remain. Those are generally unnecessary and I propose a subsequent cleanup to remove them. LC_ALL takes precedence over LANG, and while LANGUAGE takes precedence over LC_ALL, it only does so for settings other than LC_ALL=C. So LC_ALL=C on its own is sufficient to ensure the C locale, and anything that gets LC_ALL=C does not need the other settings. While preparing this patch I noticed some tests with .sh files that appeared to do nothing beyond what the generic makefile support for tests can do (localedata/tst-wctype.sh - the makefiles support -ENV variables and .input files - and localedata/tst-mbswcs.sh - just runs five tests that could be run individually from the makefile). So I propose another subsequent cleanup to move those to using the generic support instead of special .sh files.

POSIX locale descriptions and POSIX character set descriptions Ulrich Drepper Time-stamp: <2004/11/27 13:06:54 drepper> drepper@redhat.com This directory contains the data needed to build the locale data files to use the internationalization features of the GNU libc. POSIX.2 describes the `localedef' utility which is part of the GNU libc. You need this program to "compile" the locale description in a form suitable for fast access by the GNU libc functions. Any compilation is based on a given character set. Once you run `make install' for the GNU libc the data files are automatically installed in the right place, ready for use by the `localedef' program. To compile the locale data files you simply have to decide which locale (based on the location and the language) and which character set you use. E.g., French speaking Canadians would use the locale `fr_CA' and the character set `ISO_8859-1,1987'. Calling `localedef' to get the desired data should happen like this: localedef -i fr_CA -f ISO-8859-1 fr_CA This will place the 6 output files in the appropriate directory where the GNU libc functions can find them. Please note that you need permission to write to this directory ($(prefix)/share/locale, where $(prefix) is the value you specified while configuring GNU libc). If you do not have the necessary permissions, you can write the files into an arbitrary directory by giving a path including a '/' character instead of `fr_CA'. E.g., to put the new files in a subdirectory of the current directory simply use localedef -i fr_CA -f ISO-8859-1 ./fr_CA How to use these data files is described in the GNU libc manual, especially in the section describing the `setlocale' function. All problems should be reported using http://sourceware.org/bugzilla/ One more note: the `POSIX' locale definition is not meant to be used as an input file for `localedef'. It is rather there to show the values with are built in the libc binaries as default values when no legal locale is found or the "C" or "POSIX" locale is selected. The collation test suite ######################## This package also contains a (beginning of a) test suite for the collation functions in the GNU libc. The files are provided sorted. The test program shuffles the lines and sort them afterwards. Some of the files are provided in 8bit form, i.e., not only ASCII characters. So the tools you use to process the files should be 8bit clean. To run the test program the appropriate locale information must be installed. Therefore the localedef program is used to generate this data used the locale and charmap description files contained here. Since we cannot run the localedef program in case of cross-compilation no tests at all are performed. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Local Variables: mode:text eval:(load-library "time-stamp") eval:(make-local-variable 'write-file-hooks) eval:(add-hook 'write-file-hooks 'time-stamp) eval:(setq time-stamp-format '(time-stamp-yyyy/mm/dd time-stamp-hh:mm:ss user-login-name)) End:
