Split RPL into core and mode related functions. #1167

fabratu · 2014-05-14T10:20:17Z

With this PR rpl.c only contains the core RPL-functions, which include basic initialization, mutex-management, basic receiving of RPL-messages and calling mode specific functions. Each mode is now moved to its own .c/.h pair. In addition rpl.h finally got documentation.

Note: This PR does not include the by now not acknowledged PRs #1080 and #930. Therefore some code is marked as obsolete and will be altered on merge/rebase of the other PRs.

fabratu · 2014-05-17T12:26:44Z

I guess this PR will have to wait until the BBQ? (no prob, just asking)

OlegHahm · 2014-05-17T18:09:52Z

Yes, you're right.

RPL Storing mode impl?

fabratu · 2014-05-31T13:18:26Z

Fixed.

mehlis · 2014-06-12T07:58:19Z

@FabianBrandt please rebase and squash together

fabratu · 2014-06-12T22:55:18Z

Remind myself - never rebase on friday 13. Took some time - seems to be done.

Kijewski · 2014-06-12T23:30:24Z

Well, never rebase at 1 o'clock in the morning … ;)

mehlis · 2014-06-14T13:12:46Z

@FabianBrandt needs rebase again...

fabratu · 2014-06-17T10:38:15Z

Successfully rebased and updated refs/heads/rpl_base_split.

OlegHahm · 2014-06-17T21:24:08Z

Well, hm, seems to have been a very short-term success...

Kijewski · 2014-06-17T21:34:18Z

@FabianBrandt, you forgot to push the rebased branch, didn't you? :)

fabratu · 2014-06-18T10:07:53Z

Nope, pushed it ;) Maybe its about me and git. I will have a look.

Edit: found an error...

Kijewski · 2014-06-18T10:10:10Z

After your comment

Successfully rebased and updated refs/heads/rpl_base_split.

there is no new commit.

fabratu · 2014-06-18T10:56:19Z

There it is. Don´t really know what went wrong exactly. However I had to resolve a conflict, which is still stated in the commit but is not present anymore. From what I understand from git, this means, that there was a merge, which involved more than automatic resolving - which is not true actually.

OlegHahm · 2014-06-18T14:14:39Z

Maybe rename rpl_sm.c to rpl_storing.c or rpl_mop2.c? I think the current name makes it hard to guess, what's in there.

OlegHahm · 2014-06-18T14:17:00Z

sys/net/routing/rpl/rpl.c

STORING_MODE_NO_MC is not defined, right?

I would propose to call it something like RPL_MOP_2 or RPL_STORING_MODE_NO_MC.

OlegHahm · 2014-06-18T14:18:49Z

It's partly overlapping with #891, right? Could you review (and ack this) first?

OlegHahm · 2014-06-18T14:20:09Z

sys/net/routing/rpl/rpl.h

Maybe rephrase so something saying that it shouldn't be necessary to modify something in this file. Now, it sounds like: "Don't touch this file!".

OlegHahm · 2014-06-18T14:54:36Z

sys/net/routing/rpl/rpl_sm.h

Copy and paste from rpl.h?

OlegHahm · 2014-06-18T14:58:17Z

As far as I can see all function declarations in rpl_sm.h would be the same for all other modes (apart from documentation). Maybe move these declarations to something like rpl_mode.h?

fabratu · 2014-06-18T16:25:09Z

That are really some comments ... I try to look into all of it until tomorrow.

fabratu · 2014-06-18T18:57:42Z

As far as I can see all function declarations in rpl_sm.h would be the same for all other modes (apart from documentation)

@OlegHahm Depends - P2P should have other + there maybe some alterations in future. I would agree, that a certain amount of functions are common for storing/non-storing. Maybe thats a idea to split them into another file and future additions can than lead to a special rpl_[mode-name].h file.

fabratu · 2014-06-18T19:25:33Z

Based on the comments I´ve done the following:

renaming of rpl_sm.* to rpl_storing.*
several spelling and date fixes
documentation fixes
added [in] and [out] for doxygen
global variables from rpl.c got rpl_ as prefix and their declaration moved to rpl.h
added functionality from net: some debug code #891 from rpl.c and rpl.h to their new homes in rpl.c, rpl.h and rpl_storing.c for easy merging after net: some debug code #891 gets acked.

What is not done:

Functions from rpl_storing.h former rpl_sm.h are not moved into a new common mode-headerfile because the initialization in rpl.c relies on different file names for different modes. Therefore it at least needs a rpl_storing.h-headerfile. However when moving all general functions this file would be empty and only lead to confusion. After implementation of non-storing mode is finished, I will look again into this.

sys/net/routing/rpl/rpl.c

Could elaborate/document why these mutexes are necessary?

mehlis · 2014-06-24T07:59:14Z

@FabianBrandt PR needs rebase

fabratu · 2014-06-25T10:06:04Z

Fixed - suggestions inserted.

mehlis · 2014-06-25T13:41:31Z

@OlegHahm can you elaborate , I think @FabianBrandt next steps are based on this PR...

OlegHahm · 2014-06-25T17:29:17Z

Elaborate on what?

I would say ACK.

fabratu · 2014-06-27T18:08:37Z

Don´t ACK. I just recognized a problem with the buffers. I´m making a new commit this weekend.

fabratu · 2014-07-02T10:16:51Z

Buffer issue fixed. If ACK, I will rebase/squash.

OlegHahm · 2014-07-02T13:23:16Z

Can you rebase first?

fabratu · 2014-07-02T18:31:05Z

Sure. Sorry wrong button -.-

OlegHahm · 2014-07-02T20:40:50Z

sys/net/routing/rpl/rpl_storing.c

Debug should be disabled by default.

OlegHahm · 2014-07-02T20:42:13Z

Apart from the ENABLE_DEBUG setting: ACK - ready to be merged.

fabratu · 2014-07-03T18:25:34Z

Of course this should be zero. Also packet_length is no more.

OlegHahm · 2014-07-04T09:20:44Z
