Description Simon McVittie 2010-11-16 09:34:52 UTC
When we break D-Bus API we should also break C API:

- remove tp_get_bus (Bug #18832)

- don't emit TpProxy::invalidated in dispose (Bug #22119)

- remove all _run_ methods (Bug #22207)

- don't allow get_contact_statuses to fail (Bug #21796)

- get rid of everything deprecated

- replace TpChannelManagerIface.foreach_channel_class with a renamed
  TpChannelManagerIface.type_foreach_channel_class

- replace the two original TpClientChannelFactory methods with a renamed obj_*

- return void from tp_proxy_add_interface_by_id (Bug #21795)

Other possible things:

- get TpContact objects in a more GIO-ful way (Bug #27687), although this might be superseded by fixing handles

- make all async functions not re-enter (using an idle if necessary)

- check everything for introspectability and fix troublesome APIs as much as possible

-------------------------

Possibly to do, or not, depending how long the above take:

- cut as much as possible of the dbus-glib out of our API/ABI

- move to GDBus, which is probably also an ABI break, but might have to be delayed if the above take too long (Bug #28782)
Comment 1 Simon McVittie 2010-11-25 03:55:59 UTC
Additional minor things from FIXME.out:

* change tp_error_quark()'s quark to tp-error-quark

* change a GValue* in the middle of a struct to a GValue in properties-mixin.h (or just delete the entire properties mixin)
Comment 2 Simon McVittie 2010-12-16 04:13:48 UTC
Also move ChatStates support from TpChannel to TpTextChannel, following tp-qt4's lead.

13:04 < cassidy> tomeu, smcv: do you know about this kind of warnings : 
                 _gen/telepathy-enums.h:26: Warning: TelepathyGLib: 
                 symbol='NUM_TP_HANDLE_TYPES': Unknown namespace for symbol 
                 'NUM_TP_HANDLE_TYPES' 
13:05 < smcv> cassidy: it wanted us to use TP_NUM_HANDLE_TYPES or some such
13:05 < smcv> cassidy: tbh just ignore it, and make sure we use the latter in 
              the 1.0 codegen

Comment 5 Simon McVittie 2012-01-31 12:25:11 UTC
We now have a 'next' branch where we're doing this. \o/

Some things that need changing in 'next':

* --generate-all-reentrants should be --separate-reentrants or something

* Version should be < 1.0 at first (0.99.n where n is a snapshot number incremented when it's halfway stable for a bit? 0.2012.n because this is the end of the world? ...) and become 1.0 when the core library reaches API/ABI stability

* Commented-out Call stuff would be better #ifdef'd?

* "Presence Presence interface"

* tp_message_to_text should still return whether there's non-text content

I've already pushed a fix for this, admittedly as a fixup! commit and then forgot to autosquash. Oh well.

Haven't you forgotten to actually remove debug-ansi.h in this commit?

(In reply to comment #8)

You forgot to remove tp_message_new from telepathy-glib-sections.txt.

And you forgot to remove all the debug-ansi stuff from the docs (at least -docs.sgml).

Here is some more stuff that's been deprecated to remove.
Comment 12 Jonny Lamb 2012-01-31 14:48:48 UTC
... and some more fixes:

(In reply to comment #5)
> * Version should be < 1.0 at first (0.99.n where n is a snapshot number
> incremented when it's halfway stable for a bit? 0.2012.n because this is the

I've kept this at 0.99.0 for now.

> * "Presence Presence interface"

Fixed.

> * tp_message_to_text should still return whether there's non-text content

What would you prefer?

    gboolean tp_message_to_text (TpMessage *message, gchar **text);

or

    gchar * tp_message_to_text (TpMessage *message, gboolean *non_text_content);

where the former returns TRUE if there *is* text content (i.e. @text is set), and the latter returns NULL and sets @non_text_content to TRUE if there *isn't* text content... I think the former is nicer.

Also:

> * Commented-out Call stuff would be better #ifdef'd?

#ifdef'd on what?

This branch looks ideal, please merge.

There's a subtle distinction between what I'm asking for and what you seem to be suggesting: the point of the NON_TEXT_CONTENT flag was not "there is no text here", it was "by condensing this Message into plain-text, you are losing something".

Consider this composite message:

    text/plain: "hey look at this funny picture lol"
    image/jpeg: ...

This would "text-ize" as:

    ("hey look at this funny picture lol", NON_TEXT_CONTENT)

which a text-only UI could display as something like

    hey look at this funny picture lol
    [Non-text content not displayed, sorry!]

Meanwhile, this message (which could be produced automatically by a sufficiently clever CM receiving only the HTML version):

    text/html: "look at this <a href="http://...">website</a>", alternative for AAAA
    text/plain: "look at this website <http://...>", alternative for AAAA

would "text-ize" as:

    ("look at this website <http://...>", 0)

which a text-only UI would display without the apology.

I'm not sure how useful this would really be in practice, though...

> > * Commented-out Call stuff would be better #ifdef'd?

I don't know, #ifdef FIXME_REINSTATE_WHEN_CALL_IS_STABLE or something. Or you could leave them commented-out (or #if 0) and have an additional comment that's something distinctive we can grep for, or references a new bug that says "reinstate Call-related things in tp-glib when it's stable", or something.

I do agree with you that it's a good idea not to follow the usual "don't comment out code" rule in this case.

This all looks good.

I wonder if we should make TpBaseChannel check there are no duplications after calling get_interfaces?

http://cgit.freedesktop.org/~jonny/telepathy-glib/log/?h=moar-deprecations

This:

 · #ifdefs out the Call stuff. I reckon we should start generating Call code
   soon.

 · replaces NUM_TP_… defines with TP_NUM_…

 · moves chat states to TpTextChannel and adds a chat states test.

I reviewed these on Bug #46470 - sorry, missed them here.

>  · replaces NUM_TP_… defines with TP_NUM_…

Superseded by Bug #46470 which adds the new version on master, then deletes the old on next. I think that's generally a good thing to do, for things that won't cause massive bloat/effort?

I merged everything except the last commit, which needs updating (there's now one more example). I'll shunt those onto a new bug I think.

That might not be a bad idea. Having said that, it'd be O(n**2) at the moment... so perhaps not worth it.
Comment 20 Xavier Claessens 2012-05-02 15:38:58 UTC
I've searched all open bug to see all those requesting API breaks and have set them as blocking this bug. I've also reported all things I could think. Now I'm pretty confident the "Depends on" list is complete... scary how long it is...
Comment 21 Jonny Lamb 2012-07-12 14:05:23 UTC
Xavier merged master into next and removed some deprecations here:

http://cgit.collabora.com/git/user/xclaesse/telepathy-glib.git/log/?h=next-remove-deprecated

Some comments:

02050c89a381c9e9e:

You could use tp_asv_new (NULL, NULL) instead of g_hash_table_new_full (blah blah blah).

cdb02889684c082:

+ test->sms_channel = TP_TEXT_CHANNEL (tp_client_factory_ensure_channel (
+     factory, test->connection, chan_path, props, &test->error));
  g_assert_no_error (test->error);
+ g_assert (TP_IS_TEXT_CHANNEL (test->channel));

The second assertion should be test->sms_channel, no? It's also redundant (there's another too) as the TP_TEXT_CHANNEL cast will typecheck, no?

Otherwise, seems good.

+  self->priv->alias_flags = tp_asv_get_uint32 (properties, "AliasFlags", NULL);
You should check valid and raise an error if !valid.

Why are you changing the presence mixin in this commit?

my mistake, splitted the commit
