📝 Walkthrough

Walkthrough

This PR introduces IItemOrderProvider, a new Zope adapter interface for computing item ordering within a context. A default implementation enumerates context items and maps their UIDs to positions. The adapter is registered in ZCML, integrated into file session insertion logic to replace inline enumeration, and tested comprehensively.

Changes

Item Ordering Adapter Pattern

Layer / File(s)	Summary
Interface and adapter implementation src/imio/esign/interfaces.py, src/imio/esign/adapters.py, src/imio/esign/configure.zcml	IItemOrderProvider interface defines the contract for mapping item UIDs to sort positions. DefaultItemOrderProvider implements this by enumerating context items into a UID-to-index dict. Adapter is registered in ZCML for all contexts.
File session integration src/imio/esign/utils.py	Imports IItemOrderProvider and refactors add_files_to_session to use getAdapter(context, IItemOrderProvider).get_item_order() instead of inline context.values() enumeration.
Adapter tests src/imio/esign/tests/test_adapters.py	Validates DefaultItemOrderProvider returns correct UID-to-index mappings for both non-empty and empty folders, and confirms adapter integration.
Release notes CHANGES.rst	Documents improved file ordering in session for version 1.0b9.

Poem

🐰 A tidy refactor hops into view,
Where ordering logic gets its own avenue,
Adapters now handle the UID-to-slot dance,
While session files file in perfect stance! 📄✨

31-33: ⚡ Quick win

Assert complete UID→index mapping equality.

This loop validates expected keys but not unexpected extra entries in order. Build the expected mapping and assert full dict equality.

Proposed test tightening

-        children = list(folder.values())
-        for idx, child in enumerate(children):
-            self.assertEqual(order[child.UID()], idx)
+        children = list(folder.values())
+        expected_order = {child.UID(): idx for idx, child in enumerate(children)}
+        self.assertEqual(order, expected_order)

In `@src/imio/esign/tests/test_adapters.py` around lines 31 - 33, The test
currently loops over children and asserts each child's UID maps to the expected
index but doesn't catch extra keys in order; instead, construct an expected
mapping from the actual children (e.g., expected = {child.UID(): idx for idx,
child in enumerate(list(folder.values()))}) and then assert equality between
expected and order (use assertEqual(expected, order)) so the test fails on both
missing and unexpected entries; update the code around the loop that references
children, folder.values(), order, and child.UID() accordingly.
