Require function doesnt fullfil specification
---------------------------------------------
Key: COUCHDB-1151
URL: https://issues.apache.org/jira/browse/COUCHDB-1151
Project: CouchDB
Issue Type: Bug
Components: JavaScript View Server
Affects Versions: 1.0.2, 0.11.2, 1.1
Reporter: Alexander Shorin
Priority: Critical
According CommonJS Modules specification [1]:
> 4. Module identifiers may be "relative" or "top-level". A module identifier
> is "relative" if the first term is "." or "..".
> 5. Top-level identifiers are resolved off the conceptual module name space
> root.
This specification is broken in current realization at those terms. See design
test case.
Actually problems:
1. Module id is broken if module imports from same level (as via '.') or from
parent level (as via '..'). AFAIK, module id should be valid to make
require(mod.id) call successful. See`_show/relative-id`,
`_show/require-relative-id` and `_show/relative-parent-id` function.
2. Absolute module import is broken from relative imported module.
See`_show/absolute-require` function.
3. Multiple relative imports from same level(as via '.') breaks require
function. See `_show/maze` function.
Those problems makes require function works unexpectedly and obstructs solving
at least one more issue #1075 [2]
I know that all relative imports are discouraged, but if they are supported,
why they shouldn't work properly?(:
