From 37539ebee2ea9fc0daceaae1074a79de88d563fb Mon Sep 17 00:00:00 2001 From: Don Breazeal Date: Fri, 15 Jul 2016 11:19:19 -0700 Subject: [PATCH] GDB testsuite: Escape paths used in regular expressions This patch fixes problems with a few GDB testsuites when executing in a path that contains special characters (e.g. "++"). When such paths are used as a regular expression, the regular expression parser will choke and cause the tests to fail. This patch uses string_to_regexp to escape strings that will be used as regular expressions, in order to sanitize path names used in expect scripts. 2016-07-15 Zachary Welch Don Breazeal gdb/testsuite/ChangeLog: * gdb.base/maint.exp: Escape paths used in regular expressions. * gdb.stabs/weird.exp: Likewise. --- gdb/testsuite/ChangeLog | 6 ++++++ gdb/testsuite/gdb.base/maint.exp | 15 +++++++++------ gdb/testsuite/gdb.stabs/weird.exp | 3 ++- 3 files changed, 17 insertions(+), 7 deletions(-) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 5269e0e043..aaa1c9ecbe 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,9 @@ +2016-07-15 Zachary Welch + Don Breazeal + + * gdb.base/maint.exp: Escape paths used in regular expressions. + * gdb.stabs/weird.exp: Likewise. + 2016-07-13 Tom Tromey PR python/15620, PR python/18620: diff --git a/gdb/testsuite/gdb.base/maint.exp b/gdb/testsuite/gdb.base/maint.exp index f926c8b7be..e66f566088 100644 --- a/gdb/testsuite/gdb.base/maint.exp +++ b/gdb/testsuite/gdb.base/maint.exp @@ -213,12 +213,13 @@ gdb_test "maint print psymbols" \ if { ! $have_gdb_index } { set psymbols_output [standard_output_file psymbols_output] + set psymbols_output_re [string_to_regexp $psymbols_output] send_gdb "maint print psymbols $psymbols_output ${srcdir}/${subdir}/${srcfile}\n" gdb_expect { - -re "^maint print psymbols $psymbols_output \[^\n\]*\r\n$gdb_prompt $" { + -re "^maint print psymbols $psymbols_output_re \[^\n\]*\r\n$gdb_prompt $" { send_gdb "shell ls $psymbols_output\n" gdb_expect { - -re "$psymbols_output\r\n$gdb_prompt $" { + -re "$psymbols_output_re\r\n$gdb_prompt $" { # We want this grep to be as specific as possible, # so it's less likely to match symbol file names in # psymbols_output.
