From 86e887ae1183ded1c4bfba8617e4e19c8dfc8271 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Fri, 24 Apr 2020 16:21:30 +0200 Subject: [PATCH] [gdb/testsuite] Reset errcnt in clean_restart When running test-case gdb.base/readnever.exp without commit 96038148d0e "[gdb/testsuite] Skip gdb.base/readnever.exp with target board readnow", we run into an error: ... ERROR: (eof) GDB never initialized. testcase gdb/testsuite/gdb.base/readnever.exp completed in 0 seconds ... If we additionally run test-case gdb.base/realname-expand.exp, we get an unresolved for the first test: ... UNRESOLVED: gdb.base/realname-expand.exp: set basenames-may-differ on ... Using -v we find out that the UNRESOLVED is due the error triggered in the previous test-case: ... (gdb) set basenames-may-differ on^M (gdb) Error/Warning threshold exceeded: 1 0 (max. 1 3) UNRESOLVED: gdb.base/realname-expand.exp: set basenames-may-differ on ... So, the error count of one test spills into the next test, even though we do a clean restart. That seems like a bad idea. Fix this by resetting errcnt (as well as warncnt) in clean_restart, such that we have: ... Running src/gdb/testsuite/gdb.base/readnever.exp ... ERROR: (eof) GDB never initialized. Running src/gdb/testsuite/gdb.base/realname-expand.exp ... PASS: gdb.base/realname-expand.exp: set basenames-may-differ on ...
