Date: Thu, 28 Jan 2016 14:43:26 -0800 Message-ID: <1454021006-25350-1-git-send-email-donb@codesourcery.com> In-Reply-To: <56AA044A.8040900@redhat.com> MIME-Version: 1.0 X-IsSubscribed: yes This patch differs from the previous version in that the new test gdb.linespec/ls-errs-cp.exp is gone, and instead (per Pedro's suggestion) gdb.linespec/ls-errs.exp has been modified to test both C & C++, and to incorporate the small amount of extra testing from ls-errs-cp.exp. It also includes, unchanged from the previous version of the patch: * an updated version of the alternate fix that Keith proposed for my patch that addressed PR breakpoints/18303. Doug has approved (in concept, at least) the code portion of the patch. * a couple of other new tests of colons in linespecs. Thanks, --Don ----------- lookup_symbol is often called with user input. Consequently, any function called from lookup_symbol{,_in_language} should attempt to deal with malformed input gracefully. After all, malformed user input is not a programming/API error. This patch does not attempt to find/correct all instances of this. It only fixes locations in the code that trigger test suite failures. This patch fixes PR breakpoints/18303, "Assertion: -breakpoint-insert with windows paths of file in non-current directory". The patch includes three new tests related to this. One is just gdb.linespec/ls-errs.exp copied and converted to use C++ instead of C, and to add a case using a file name containing a Windows-style logical drive specifier. The others include an MI test to provide a regression test for the specific case reported in PR 18303, and a C++ test for proper error handling of access to a program variable when using a file scope specifier that refers to a non-existent file. Tested on x86_64 native Linux. gdb/ChangeLog 2016-01-28 Keith Seitz PR breakpoints/18303 * cp-namespace.c (cp_lookup_bare_symbol): Change assertion to look for "::" instead of simply ":".
