Is it time to re-think how UnicodeUtil::getConversionICU() search
for ICU library ?
Suggestions?
The fastest way sooner of all will be storing favorite ICU verson
(once detected using long process) somewhere out of databases. But
may be some better idea?
I see "icu_versions" parameter at fbintl.conf but it seems not used
by getConversionICU().
Probably it could be used here ?
Not sure is it needed or not currently (Adriano should know better) -
but I dislike an idea of making .conf files firebird-writable for
security reasons.
Also, we could limit number of ICU versions to check:
- exclude really old versions (at least with old X.Y versioning
scheme, i.e. 4.8 and older)
Suppose we may exclude versions missing TZ support needed for FB4. What
about versioning scheme - now it depends upon build parameters and
therefore in linux is distro-depended. Not good criteria IMHO :)
- adapt search knowing existing versions numbers (see
http://site.icu-project.org/download)
Yes, this should be efficient.
- guess number of future versions
Ask the spirit of Vanga? ;)
Getting serious we may just decrease number of future versions to
analyze - anyway they will invent something making that versions not
loadable with current code.
