Description megabaks 2013-04-06 17:06:45 UTC

dev-libs/icu-51.1 has subslot 50.1
after updating from 50.1.2 all packages depend on icu (over sqlite[icu] too) will be broken.
so, subslot must be 51.1
/sorry my bad english

Reproducible: Always

Sorry about that, its fixed.  Thanks for the report.

>so, subslot must be 51.1

Your suggestion is wrong:
Nothing links to libicuuc.so.51.1 or libicuuc.so.51.2 in my systems, all packages link to libicuuc.so.51. When i updated icu from 51.1 to 51.2 emerge recompiled a lot packages without any good reason.
libicuuc.so.51.1 was not preserverd, 'emerge -vp @preserved-rebuild' was empty when emerge installed icu and was rebuilding packages. 
Wasting time for rebuilding libreoffice is not fun, please fix SLOT in icu ebuilds.

add to make.conf:
EMERGE_DEFAULT_OPTS="--ignore-built-slot-operator-deps=y"

As far as I can remember, icu consumers reacted rather sensitive to icu upgrades in the past. Even if revdep-rebuild did not rebuild (i.e. soname did not change), random crashes and other irregularities occured until the consumers were rebuilt. So from me, this is for now a wontfix.

Comment 5 Nikoli 2013-11-01 20:07:58 UTC

Then add comment to ebuild near SLOT= about this problem, else it is far from obvious.

(In reply to Andreas K. Hüttel from comment #4)

ICU provides 5 public libraries. In the past, there happened sonameless changes of ABI of 1 of these libraries (libicule), which is used by almost no reverse dependency. (libicule is used by app-office/libreoffice.)

(Subslot dictionaries will be proper solution. ICU will need 8 items in its subslot dictionary.)

Yes, it is recommended to do that.

Done, with a reference to this bug here. 

IMHO we can revisit this in a few releases and relax the condition if we think upstream behaves more sanely. Or if we have the subslot dicts.
