From dca0f6c0a4bafff9039d8bdb2a7efec9f70ce82f Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 13 Jun 2019 00:06:52 +0100 Subject: New set/show testing framework (gdb.base/settings.exp) This commit adds new representative commands for all types of settings commands supported by gdb (enum var_types), and then uses them to exercise settings parsing and completion. (gdb) maint test-settings s[TAB] set show (gdb) maint test-settings set [TAB] auto-boolean integer uinteger boolean optional-filename zinteger enum string zuinteger filename string-noescape zuinteger-unlimited (gdb) maint test-settings set enum [TAB] xxx yyy zzz etc. This is basically unit testing, except that it goes fully via GDB. It must be done this way in order to exercise TAB completion properly, which must go via readline. gdb/ChangeLog: 2019-06-13 Pedro Alves * Makefile.in (COMMON_SFILES): Add maint-test-settings.c. * NEWS: Mention maint test-settings KIND. * maint-test-settings.c: New file. gdb/doc/ChangeLog: 2019-06-13 Pedro Alves * gdb.texinfo (Maintenance Commands): Document "maint test-settings" commands. gdb/testsuite/ChangeLog: 2019-06-13 Pedro Alves * gdb.base/settings.c: New file. * gdb.base/settings.exp: New file. --- gdb/ChangeLog | 6 + gdb/Makefile.in | 1 + gdb/NEWS | 4 + gdb/doc/ChangeLog | 5 + gdb/doc/gdb.texinfo | 6 + gdb/maint-test-settings.c | 257 +++++++++++++++++ gdb/testsuite/ChangeLog | 5 + gdb/testsuite/gdb.base/settings.c | 23 ++ gdb/testsuite/gdb.base/settings.exp | 539 ++++++++++++++++++++++++++++++++++++ 9 files changed, 846 insertions(+) create mode 100644 gdb/maint-test-settings.c create mode 100644 gdb/testsuite/gdb.base/settings.c create mode 100644 gdb/testsuite/gdb.base/settings.exp diff --git a/gdb/ChangeLog b/gdb/ChangeLog index f1354de..1828a74 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,11 @@ 2019-06-13 Pedro Alves + * Makefile.in (COMMON_SFILES): Add maint-test-settings.c. + * NEWS: Mention maint test-settings KIND. + * maint-test-settings.c: New file. + +2019-06-13 Pedro Alves + * cli/cli-decode.c (add_setshow_cmd_full): Remove "show" completer.
