It's not uncommon to see in a gentoo kde ebuild, that it must extract 
(not build, just extract) not only the package it's building from the big 
module tarball, but one or more others as well.  This is common enough 
that the kde eclasses (eclasses are package or functionality specific 
procedure libraries common to a number of versions and possibly multiple 
packages, in this case kde specific) have special handling for this.

In fact, they have KMEXTRACTONLY, which only extracts the listed subdirs 
in the module tarball, without compiling or installing, and KMCOMPILEONLY, 
which extracts and compiles but does not install. (KM is short for KDE 
module.)  There's also KMEXTRA, which does the whole thing, extract, 
compile and install, as part of the package.

And indeed, the kmail ebuild makes use of all three, with extract-only 
listing akonadi_next, calendarsupport, korganizer, kresources... Compile-
only lists messagecomposer, messagecore... calendarsupport (they aren't 
supposed to list a subdir in both, but it appears they did with 
calendarsupport... I wonder if that's why they ended up depending on 
korganizer to get it to work??).  Extra (full build) lists kmailcvt, 
ksendemail... ontologies...

But here, for whatever reason (maybe the bug above, calendarsupport 
listed in both extractonly and compileonly?), they make korganizer a full 
dependency, thus forcing build and install of korganizer first, before 
kmail can be built and installed.

FWIW, here if you want to take a look at the actual ebuild (tho it looks 
much nicer with syntax color hiliting, this isn't an implication that I 
expect it, only if you'd find it interesting to see what an actual 
implementation looks like).  It's quite high-level and shouldn't be too 
complicated for an outsider to get a general picture from, anyway.


And here's the first-level inherited eclass, kde4-meta.eclass, if you 
want, tho this has a lot more (basically bash) code.  It does further 
inherits but you can change the link manually to get them, if desired.

Indeed.  But adding that ability means the code to create that calendar 
entry must be in kmail too, or "borrowed" from korganizer in the form of 
a dependency, which is how I'm interpreting this, assuming it's not the 
double-specified bug above or simply a mistake of some sort.

That's actually a question I had, but hadn't asked (or tried) yet, 
whether email searches, etc, now require nepomuk.  I'll probably enable 
it for that at some point, but the basic functionality that I use 
normally, doesn't require it, and there's still a bit of weirdness going 
on (every time a mail comes in, I get a warning about two copies... I 
suspect I have two different resources pointed at the same place or 
something but haven't had a chance to investigate yet... but don't spend 
too much time on that unless you happen to have a simple solution or bug 
you can point me to, as I'll create a separate thread for it when I'm 
ready, given that it's really a separate topic and this thread's 
convoluted enough already), so I'm not worried about /extra/ 
functionality yet, just trying to keep it reasonably simple to deal with 
until I'm sure the basics are working correctly.

Based on this subthread I'll probably do a bug-search, and then possibly 
ask, if necessary.  Plus, I have that double-include, in both extractonly 
and compileonly, to look into.  I just spotted that as a result of 
listing them, above.  The comments/instructions at the top of the kde4-
meta.eclass are very specific about not doing that, which makes sense, 
given the intended functionality.

Unlike the thread OP, I did NOT have a previous kmail2 attempt around.  
While my kmail installation is ~a decade old, and thus no doubt has 
various cruft (including the original import from OE5, which goes back 
another half-decade) in that regard, it was clean in terms of previous 
kmail2 attempts as I had been very careful NOT to try such a thing until 
full release.

Good point.  Since I'm all pop3 (plus a machine-local maildir), I tend 
not to think about the IMAP folks.  Glad someone does! =:^)

That's a reasonable explanation.  I found the fact that the migrator log 
mentions the pop3 accounts and even the local sysmail account, but says 
nothing at all about an error or an unaccountably missing localfolders 
rather interesting, but a one-by-one treatment with no overall view of 
things, particularly given folks who many not have local storage, only 
IMAP, so a missing local store probably in itself isn't incredibly weird, 
makes some sense.  When the one-by-one got to that point, for whatever 
reason, it must have simply detected absolutely nothing, so there was no 
error/warning to log, because there wasn't an overall view to raise that

Yes.  By that point the migrator had finished, failing to detect the 
local mail store at all, according to the migrator log which has no 
mention of it, no errors, nothing.  So I was doing the manual import 

But I had assumed that the migrator was simply an automatic trigger for 
what would otherwise be a manual import/conversion process, thus more or 
less conflating them in my discussion, I suppose.  It appears that I 
assumed wrong, and they're two entirely separate things.

Thanks for clearing that up.  It's very possible that will help with 
others down the line, as well.

It would appear so.

Well, I'm done with that for now... unless something happens and I end up 
having to redo it a fourth time...  The "pleasures" of beta! =:^\

But again, that's likely to be a very useful hint for others, when they 
come calling.

What I found interesting was that it wasn't /all/ messages unread or all 
read, it was /mostly/ unread.  If there wasn't support for the index 
files at all, they should all be unread (or all read, arbitrary choice of 
the importer).

BTW, in an admittedly rather naive attempt to clear up that two-copies 
thing I'm getting on every incoming mail as mentioned above, I decided 
that the local-folders resource must duplicate something builtin, thus 
triggering the duplicate warnings, so tried to delete it (!! yes, I SAID 
rather naive!!).  I quickly realized my mistake as the disks churned, but 
as I still have the old data, I decided it was probably best to just let 
it go and deal with whatever it left me when it was done.

What happened was that as it tried to delete the outbox, etc, kmail 
crashed.  When it returned, everything was still there (automatically 
recreated resource? final commit not made due to crash so it recovered?), 
but all the messages were again marked unread.

So I had to go thru and again mark everything read, in all my dozens of 
dirs.  Then I had to go thru and re-configure all my dozens (50-ish) of 
mailfilters to point to valid folders once again.

Oh, well, can't complain as I expected to have to do the imports again as 
well, but apparently, someone had the insight to think of someone 
accidentally deleting their main local-folders resource, and thus 
automatically recovered it.  So "all" I had to do was mark everything 
read again, and re-point the filters at valid folders, again.

The upside is that I've done the mark-read, re-point filters dance enough 
times now that it was a rather faster process this time than the first!

Yes, it does...
