This patch fixes the code to avoid that. gdb/ChangeLog: PR gdb/17856: * ada-lang.c (ada_lookup_symbol_list_worker): Do not re-cache results found in the cache. Tested on x86_64-linux, no regression.
2015-02-02[Ada] pspace_data->sym_cache is always NULLJoel Brobecker2-5/+10
The Ada symbol cache has been designed to have one instance of that of that cache per program space, and for each instance to be created on-demand. ada_get_symbol_cache is the function responsible for both lookup and creation on demand. Unfortunately, ada_get_symbol_cache forgot to store the reference to newly created caches, thus causing it to: - Leak old caches; - Allocate a new cache each time the cache is being searched or a new entry is to be inserted. This patch fixes the issue by avoiding the use of the local variable, which indirectly allowed the bug to happen. We manipulate the reference in the program-space data instead. gdb/ChangeLog: PR gdb/17854: * ada-lang.c (ada_get_symbol_cache): Set pspace_data->sym_cache when allocating a new one.

2015-01-31Move TYPE_SELF_TYPE into new field type_specific.Doug Evans9-67/+189
This patch moves TYPE_SELF_TYPE into new field type_specific.self_type for MEMBERPTR,METHODPTR types, and into type_specific.func_stuff for METHODs, and then updates everything to use that. TYPE_CODE_METHOD could share some things with TYPE_CODE_FUNC (e.g. TYPE_NO_RETURN) and it seemed simplest to keep them together. Moving TYPE_SELF_TYPE into type_specific.func_stuff for TYPE_CODE_METHOD is also nice because when we allocate space for function types we assume they're TYPE_CODE_FUNCs. If TYPE_CODE_METHODs don't need or use that space then that space would be wasted, and cleaning that up would involve more invasive changes. In order to catch errant uses I've added accessor functions that do some checking. One can no longer assign to TYPE_SELF_TYPE like this: TYPE_SELF_TYPE (foo) = bar; One instead has to do: set_type_self_type (foo, bar); But I've left reading of the type to the macro: bar = TYPE_SELF_TYPE (foo); In order to discourage bypassing the TYPE_SELF_TYPE macro I've named the underlying function that implements it internal_type_self_type. While testing this I found the stabs reader leaving methods as TYPE_CODE_FUNCs, hitting my newly added asserts. Since the dwarf reader smashes functions to methods (via smash_to_method) I've done a similar thing for stabs. gdb/ChangeLog: * cp-valprint.c (cp_find_class_member): Rename parameter domain_p to self_p.

2015-01-31Add max-completions parameter, and implement tab-completion limiting.Gary Benson10-24/+478
This commit adds a new exception, MAX_COMPLETIONS_REACHED_ERROR, to be thrown whenever the completer has generated too many candidates to be useful. A new user-settable variable, "max_completions", is added to control this behaviour. A top-level completion limit is added to complete_line_internal, as the final check to ensure the user never sees too many completions. An additional limit is added to default_make_symbol_completion_list_break_on, to halt time-consuming symbol table expansions. gdb/ChangeLog: PR cli/9007 PR cli/11920 PR cli/15548 * cli/cli-cmds.c (complete_command): Notify user if max-completions reached. * common/common-exceptions.h (enum errors) <MAX_COMPLETIONS_REACHED_ERROR>: New value. * completer.h (get_max_completions_reached_message): New declaration.

2015-01-30Constify some parameters in the varobj codeSimon Marchi6-79/+137
To make it clear that some functions should not modify the variable object, this patch adds the const qualifier where it makes sense to some struct varobj * parameters. Most getters should take a const pointer to guarantee they don't modify the object. Unfortunately, I couldn't add it to some callbacks (such as name_of_child). In the C implementation, they call c_describe_child, which calls varobj_get_path_expr. varobj_get_path_expr needs to modify the object in order to cache the computed value. It therefore can't take a const pointer, and it affects the whole call chain. I suppose that's where you would use a "mutable" in C++. I did that to make sure there was no other cases like the one fixed in the previous patch. I don't think it can hurt. gdb/ChangeLog: * ada-varobj.c (ada_number_of_children): Constify struct varobj * parameter. (ada_name_of_variable): Same. (ada_path_expr_of_child): Same.

2015-01-30Set varobj->path_expr in varobj_get_path_exprSimon Marchi3-8/+20
It seems like different languages are doing this differently (e.g. C and Ada). For C, var->path_expr is set inside c_path_expr_of_child. The next time the value is requested, is it therefore not recomputed. Ada does not set this field, but just returns the value. Since the field is never set, the value is recomputed every time it is requested. This patch makes it so that path_expr_of_child's only job is to compute the path expression, not save/cache the value. The field is set by the varobj common code. gdb/ChangeLog: * varobj.c (varobj_get_path_expr): Set var->path_expr. * c-varobj.c (c_path_expr_of_child): Set local var instead of child->path_expr.
