On aarch64-linux (debian testing) with test-case gdb.base/empty-host-env-vars.exp I ran into: ... (gdb) show index-cache directory^M The directory of the index cache is "/home/linux/.cache/gdb".^M (gdb) FAIL: $exp: env_var_name=HOME: show index-cache directory ... Without changing any environment variables, the value of the index-cache dir is: ... $ gdb -q -batch -ex "show index-cache directory" The directory of the index cache is "/home/linux/.cache/gdb". ... and the expectation of the test-case is that setting HOME to empty will produce an empty dir, but what it actually produces is: ... $ HOME= gdb -q -batch -ex "show index-cache directory" The directory of the index cache is "/home/linux/.cache/gdb". ... There's nothing wrong with that behaviour, the dir is simply constructed using XDG_CACHE_HOME which happens to be explictly set to its default value $HOME/.cache [1]: ... $ echo $XDG_CACHE_HOME /home/linux/.cache ... and indeed also setting that variable to empty gets us the expected empty dir: ... $ XDG_CACHE_HOME= HOME= gdb -q -batch -ex "show index-cache directory" gdb: warning: Couldn't determine a path for the index cache directory. The directory of the index cache is "". ... Furthermore, the test-case assumption that setting variables to empty either produces the original dir or an empty dir is incorrect. Say that XDG_CACHE_HOME has a non-default value: ... $ echo $XDG_CACHE_HOME /home/linux/my-xdg-cache-home $ gdb -q -batch -ex "show index-cache directory" The directory of the index cache is "/home/linux/my-xdg-cache-home/gdb". ... then setting that variable to empty: ... $ XDG_CACHE_HOME= gdb -q -batch -ex "show index-cache directory" The directory of the index cache is "/home/linux/.cache/gdb". ... does change the value of the dir. Fix this by making the test-case less specific. While we're at it, factor out regexps re_pre and re_post to make regexps more readable, and use string_to_regexp to reduce quoting. Tested on aarch64-linux. PR testsuite/32132 Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=32132 [1] https://specifications.freedesktop.org/basedir-spec/latest/index.html#variables |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
