Description Jonny Lamb 2012-05-10 07:49:15 UTC
Will and I were just thinking about whether we could have Telepathy 0.20 and 1.0 installed at the same time. Given they've changed bus names there's no conflict there at all, but we can't have old and new gabble installed due to manager file conflict.

Here's a list of things that will need to be changed:

    /usr/share/telepathy → /usr/share/telepathy-1

    ~/.mission-control → [something, also see bug #35896]

Anything else?
Comment 1 Simon McVittie 2013-10-29 11:12:26 UTC
Low-hanging fruit:

* Move .client files to ${datadir}/telepathy-1/clients
  [spec, MC, tp-glib?, Logger, Empathy, all regression tests]

* Move .manager files to ${datadir}/telepathy-1/managers
  [spec, tp-glib, MC?, all CMs, all regression tests including Folks]

* Decide whether Telepathy 0 and Telepathy 1 can safely share the avatar cache
  (I think the answer is probably "yes")
  [spec, tp-glib]

* Make MC load accounts from ${XDG_DATA_DIRS}/telepathy-1/mission-control
  or maybe ${XDG_DATA_DIRS}/telepathy-1/accounts - for now, load *only*
  from there, and I'll file a separate bug for a migration step
  (see also Bug #54875 which introduces a more sensible account storage
  format, "some stringified GVariants")
  [MC]

* Make MC use a different file for its crash-recovery state dump
  [MC]

* rename Telepathy-1.gir to Telepathy1-1.gir? (ask g-i people
  whether this is desirable?)
  [tp-glib, Folks, ...]

* make MC install mc6-tool (or maybe rename to telepathy-account)
  and mc6-wait-for-name
  [MC]

* make sure all docs, etc. are parallel-installable, for instance
  by installing Telepathy 0 and Telepathy 1 to separate clean prefixes
  and scripting a comparison
  [tp-glib, MC, Logger, tp-farstream]
Comment 2 Simon McVittie 2013-10-29 11:14:10 UTC
I opened Bug #70990 separately since it's more involved.

Neither tp-glib or its unit tests uses client files so I think that's all of them.

++ as a starting point, although we should also check the various fallback paths that it uses. I think we should perhaps "#if 0" the handling of ~/.missioncontrol for now, and reinstate it when we've worked out how old-account importing/migration works.

It's still not clear what's the right answer here. I'd vote for 'Telepathy1-0.gir' I think.

Still to do, but I still think it's OK.

One of the GNOME people explained in #telepathy that it's conventional to keep the same .gir name even in new ABI versions. It's actually entirely possible to select a GIR version in at least PyGI and gjs, so I'm inclined to say "whatever, let's keep it TelepathyGLib", and patch GNOME Shell (perhaps also GNOME Chat and Polari if they're g-i) to explicitly ask for "0.12" until it's ported.

The Logger still installs:

/opt/telepathy-1.0/share/glib-2.0/schemas/org.freedesktop.Telepathy.Logger.gschema.xml

/opt/telepathy-1.0/libexec/telepathy-logger

The former might need to use clever dconf aliasing like MC does.

The latter is really easy.

In addition, we need to decide how to make the actual logs compatible (Bug #70990).

review+ for now. In Bug #70991 I would suggest that the right way would be to make it runtime-conditional: give McdAccountManagerDefault the ability to be instantiated in "old mode" (which would read from those old locations) and do something like this:

* normally, instantiate a normal McdAccountManagerDefault
* when starting up and ~/.local/share/telepathy/mission-control/migrated-to-v6.stamp doesn't exist:
  * instantiate a read-only, "old mode" McdAccountManagerDefault
  * enumerate all its accounts
  * copy them into the "real" McdAccountManagerDefault
  * dispose the "old" McdAccountManagerDefault
