Subject: [PATCH 3/3] build: auto-load ICU data from
|
|
--with-icu-default-data-dir
|
|
|
|
When compiled with `--with-intl=small` and
|
|
`--with-icu-default-data-dir=PATH`, Node.js will use PATH as a
|
|
fallback location for the ICU data.
|
|
|
|
We will first perform an access check using fopen(PATH, 'r') to
|
|
ensure that the file is readable. If it is, we'll set the
|
|
icu_data_directory and proceed. There's a slight overhead for the
|
|
fopen() check, but it should be barely measurable.
|
|
|
|
This will be useful for Linux distribution packagers who want to
|
|
be able to ship a minimal node binary in a container image but
|
|
also be able to add on the full i18n support where needed. With
|
|
this patch, it becomes possible to ship the interpreter as
|
|
/usr/bin/node in one package for the distribution and to ship the
|
|
data files in another package (without a strict dependency
|
|
between the two). This means that users of the distribution will
|
|
not need to explicitly direct Node.js to locate the ICU data. It
|
|
also means that in environments where full internationalization is
|
|
not required, they do not need to carry the extra content (with
|
|
the associated storage costs).
