Subject: Change: imported modules are not resolved relative to current dir.
X-Git-Tag: 0.8.3~10
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=8fd9bd0930990eb2d4f6b5046328415b6cb715e5;p=njs.git

Change: imported modules are not resolved relative to current dir.

Previously, when a module was imported with a relative path
it was looked for first in the directory of the importing context
(global, or a module).

For example when:
    main.js:
        import libs/lib1.js;

    libs/lib1.js:
        import lib2.js;

lib2.js was looked for first in libs/.

Now, it is only looked for in directories speficied with js_path
and a directory of nginx configuration file.
