Consider the following example:
% gdb -q -batch -ex 'source nonexistant-file'
[nothing]
One would have at least expected the debugger to warn about
not finding the file, similar to the error shown when using
a more interactive mode. Eg:
(gdb) source nonexistant-file
nonexistant-file: No such file or directory.
Not raising an error appears to be intentional, presumably in order
to prevent this situation from stoping the execution of a GDB script.
But the lack of at least a warning makes it harder for a user to
diagnose any issue, if the file was expected to be there and readable.
This patch adds a warning in that case:
% gdb -q -batch -ex 'source nonexistant-file'
warning: nonexistant-file: No such file or directory.
gdb/ChangeLog:
* utils.h (perror_warning_with_name): Add declaration.
* utils.c (perror_warning_with_name): New function.
* cli/cli-cmds.c (source_script_with_search): Add call to
perror_warning_with_name if from_tty is nul.
gdb/testsuite/ChangeLog:
* gdb.base/source-nofile.gdb: New file.
* gdb.base/source.exp: Add two tests verifying the behavior when
the "source" command is given a non-existant filename.
