Description Russell Sandish 2020-04-15 03:33:36 UTC
Emacs does not correctly fire up gdb when run using its gdb command. The error message is "Error: you did not specify -i=mi on GDB’s command line!". It turns out when running gdb with the option -i=mi, the following python errors are output on standard error: /usr/share/gdb/python/gdb/command/prompt.py:48: SyntaxWarning: "is not" with a literal. Did you mean "!="? if self.value is not '': /usr/share/gdb/python/gdb/command/prompt.py:60: SyntaxWarning: "is not" with a literal. Did you mean "!="? if self.value is not '': =thread-group-added,id="i1" The workaround is to edit /usr/share/gdb/python/gdb/command/prompt.py and replace the two instances of "is not" with "!=". It is, I think a python 2 -> python 3 compatibility issue. != is the correct operator to use in this circumstance, but apparently "is not" worked well enough in python 2 the bug never surfaced before. Perhaps a patch could be applied to OpenSUSE's gdb package to fix this error until it is fixed upstream.

Fixed upstream by: commit b6484282f85bf7f11451b2441599c241d302ad9d Author: Raul Tambre <email@example.com> Date: Sat May 4 15:48:17 2019 -0400 Fix incorrect use of 'is' operator for comparison in python/lib/gdb/command/prompt.py The 'is' operator is not meant to be used for comparisons. It currently working is an implementation detail of CPython. CPython 3.8 has added a SyntaxWarning for this. diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 383b353339..7eb5d9aef3 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,9 @@ +2019-05-04 Raul Tambre <firstname.lastname@example.org> + + * python/lib/gdb/prompt.py (_ExtendedPrompt) + <before_prompt_hook, get_show_string>: Fix incorrect use of 'is' + operator for comparison. + 2019-05-04 Tom Tromey <email@example.com> * psymtab.c (psymbol_name_matches, match_partial_symbol) diff --git a/gdb/python/lib/gdb/command/prompt.py b/gdb/python/lib/gdb/command/prompt.py index 3d662a7d3f..04b9e49c22 100644 --- a/gdb/python/lib/gdb/command/prompt.py +++ b/gdb/python/lib/gdb/command/prompt.py @@ -45,7 +45,7 @@ The currently defined substitutions are: self.hook_set = False def get_show_string (self, pvalue): - if self.value is not '': + if self.value: return "The extended prompt is: " + self.value else: return "The extended prompt is not set." @@ -57,7 +57,7 @@ The currently defined substitutions are: return "" def before_prompt_hook(self, current): - if self.value is not '': + if self.value: return gdb.prompt.substitute_prompt(self.value) else: return None
