[PATCH 0/3] Factor code on suppress MI notification

[PATCH 0/3] Factor code on suppress MI notification

[Yao Qi]

Hi,
When writing new MI notifications, I have to add 'else if (strncmp())'
stuff to suppress each new MI notification, and I don't like this way.
This patch set is to factor the code on notification suppressing.
Patch 3/3 is the major part of this set, which adds a new field
'called' in 'struct mi_cmd', and associate this field of each mi_cmd
to the flag of suppress notification we already have.  It is simple
that when we want to add a new flag to suppress some notifications.

Patch 1/3 is obvious, and I'll apply it.  Patch 2/3 is to define two
new macros to simply the struct initialization in array 'mi_cmds'.

Regression tested on x86_64-linux with native and gdbserver.  OK to
apply?

[PATCH 2/3] new macro DEF_MI_CMD_CLI and DEF_MI_CMD_MI.

[Yao Qi]

Hi,
This patch is to refactor array mi_cmds to use macros to initialize
each struct, and it will be easier to modify 'struct mi_cmd' in my
next patch.

gdb:

2012-08-27  Yao Qi  <yao@codesourcery.com>

	* mi/mi-cmds.c (mi_cmds): New macros DEF_MI_CMD_CLI and
	DEF_MI_CMD_MI.  Adjust it.

[PATCH 3/3] suppress notification

[Yao Qi]

Hi,
This patch is to change the existing 'suppress mechanism' to avoid
adding endless command name comparisons to suppress corresponding MI
notification.  This patch adds a new field 'called' in 'struct
mi_cmd', so that each MI command has a 'suppressed' flag associated to
it, and we don't have to compare command name anymore.

gdb:

2012-08-27  Yao Qi  <yao@codesourcery.com>

	* mi/mi-cmds.c (mi_cmds): New macro DEF_MI_CMD_CLI_1
	and DEF_MI_CMD_CLI_1.  Update some commands.
	* mi/mi-cmds.h (struct mi_cmd) <called>: New field.
	* mi/mi-main.c (mi_cmd_execute): Set '*parse->cmd->called' to 1.

Hi Yao,

I am not 100% sure this is ideal approach. Your comment say:

> +  int *called;

But in practice, this is pointer that points to notification that must be supressed when this
command is running. So, at least the comment is misleading. And if some other code will
want to check whether the current command is A, it would have to look at notification
flags.

So, at the very least, this field should have a different name, I think.

Thanks,
Volodya

Although field 'called' is added for notification suppressing, but I 
don't couple this field to notification suppressing.  Ideally, field 
'called' is set to 1 when the command/function is called, as comment 
says, and set back to 0 when it is done.  At this point, it has nothing 
to do with notification suppressing, and we use this field to do 
something else in a free way.

When we want to suppress notification, we make use of the feature of 
field 'called'.   I am not sure it is misleading.

If you still think it is misleading, I'd like to rename variable 
'mi_suppress_notification' to 'mi_cmd_called'.  WDYT?

Well, the problem is that this is not a generic mechanism to everybody to know whether command X is presently running -- because
this mechanism can set only one variable, and for some commands that variable is already notification flag.

> If you still think it is misleading, I'd like to rename variable 'mi_suppress_notification' to 'mi_cmd_called'.  WDYT?

Would that be any better than just storing the name of current command and check it with strcmp? Yeah, we're back to where
we've started. What is the problem we're trying to solve? That strcmp is ugly to type and not entirely efficient?

If we want to know whether command X is running, we can add more fields 
in 'struct mi_suppress_notification', and each field is associated with 
one command in this way (set 'called' point to the address of field in 
'struct mi_suppress_notificatin').  It is unnecessary according to 
current requirement, and it can evolve easily once we have such 
requirement in the future.

I am adding some MI notifications, which should be suppressed.  The 
problem I have is that we'll have a very long 'if/else if/else if/.../' 
blocks to compare command name to determine which suppress flag to set. 
  The code smell is not good to me.  So I draft these patches to change it.

Ideally, we can do this in a more-OO'ed manner,

   1 add a new field 'int called' in 'struct mi_cmd',
   2 set 'parse->cmd->called' in mi_cmd_execute to 1 and set it back to 
0 when it is done.
   3 pass 'struct mi_cmd *' to each MI command function, for example 
change function mi_breakpoint_created to

   mi_breakpoint_created (struct mi_cmd *self, struct breakpoint *b)

   4 inside each MI command function, return early if self->called is 1. 
  Then, we can get rid of mi_suppress_notification completely.

This will lead to more changes, so I don't implement it.  If it is 
acceptable to you, I can go to this way.

Alternatively, set the notification suppression down in the command callback itself.
I mention it for completeness.  Maybe you've considered it, and decided against it.

Confused.  mi_breakpoint_created is not a MI command function, but rather a
notification observer.  Whoever calls the observers (observer_notify_breakpoint_created)
is disconnected from commands, and I don't see that the coupling would be a good idea.

Are you suggesting that we can set breakpoint suppression flag in each 
breakpoint related CLI commands, such as "delete breakpoint", "disable 
breakpoint", and so forth?

Not really a strong suggestion, but more like it seemed like the obvious
first choice to me, so I wondered if you considered and discarded it.
You wouldn't do it within the CLI commands.  Instead you'd expand:

  { "break-delete", { "delete breakpoint", 1 }, NULL },

into something like

  { "break-delete", { NULL, 0 }, mi_cmd_break_delete },

and then mi_cmd_break_delete would suppress the notification and
call "delete breakpoint" itself.  Or a core API function to break
the CLI dependency (which might be a good idea anyway).
