Subject: [PATCH 1/5] gdb/testsuite: fix occasional failure in gdb.base/clear_non_user_bp.exp
Date: Fri, 31 Mar 2023 21:20:54 +0100 [thread overview]
Message-ID: <62e7b6208a24dea949d901aa1945a87e8683478e.1680293848.git.aburgess@redhat.com> (raw)
In-Reply-To: <cover.1680293848.git.aburgess@redhat.com>
I noticed that the gdb.base/clear_non_user_bp.exp test would sometime
fail when run from a particular directory.
The test tries to find the number of the first internal breakpoint
using this proc:
proc get_first_maint_bp_num { } {
gdb_test_multiple "maint info break" "find first internal bp num" {
-re -wrap "(-\[0-9\]).*" {
return $expect_out(1,string)
}
}
return ""
}
The problem is, at the time we issue 'maint info break' there are both
internal breakpoint and non-internal (user created) breakpoints in
place. The user created breakpoints include the path to the source
file.
Sometimes, I'll be working from a directory that includes a number,
like '/tmp/blah-1/gdb/etc', in which case the pattern above actually
matches the '-1' from 'blah-1'. In this case there's no significant
problem as it turns out that -1 is the number of the first internal
breakpoint.
Sometimes my directory name might be '/tmp/blah-4/gdb/etc', in which
case the above pattern patches '-4' from 'blah-4'. It turns out this
is also not a problem -- the test doesn't actually need the first
internal breakpoint number, it just needs the number of any internal
breakpoint.
But sometimes my directory name might be '/tmp/blah-0/gdb/etc', in
which case the pattern above matches '-0' from 'blah-0', and in this
case the test fails - there is no internal breakpoint '-0'.
Fix this by spotting that the internal breakpoint numbers always occur
after a '\r\n', and that they never start with a 0. Our pattern
becomes:
-re -wrap "\r\n(-\[1-9\]\[0-9\]*).*" {
return $expect_out(1,string)
}
After this I'm no longer seeing any failures.
