Gemini emits backticks instead of the end of a CDATA section #70

Closed kgilpin closed 1 month ago

This problem is somewhat common:

Failed to parse change: <change>
<file change-number-for-this-file="1">django/db/models/query.py</file>
<original line-count="7" no-ellipsis="true"><![CDATA[
        inserted_rows = []
        bulk_return = connections[self.db].features.can_return_rows_from_bulk_insert
        for item in [objs[i:i + batch_size] for i in range(0, len(objs), batch_size)]:
            if bulk_return and not ignore_conflicts:
                inserted_columns = self._insert(
```</original>
<modified line-count="7" no-ellipsis="true"><![CDATA[
        inserted_rows = []
        bulk_return = connections[self.db].features.can_return_rows_from_bulk_insert
        batch_size = min(batch_size, max(ops.bulk_batch_size(fields, objs), 1)) if batch_size else max(ops.bulk_batch_size(fields, objs), 1)
        for item in [objs[i:i + batch_size] for i in range(0, len(objs), batch_size)]:
            if bulk_return and not ignore_conflicts:
                inserted_columns = self._insert(
```</modified>
</change>

This can be fixed up pretty reliably by detecting these mistakes with </original> and </modified> and fixing them up to be valid; then reparsing.

Title: Fix improper closing of CDATA sections in Gemini change logs

Problem: In the process of parsing change logs from Gemini, CDATA sections are terminated with backticks instead of proper closing tags, leading to parsing failures. These incorrect terminations usually occur at the end of CDATA sections within <original> and <modified> tags.

Analysis: The parsing failure is due to a mismatch in the closing syntax for CDATA sections. Instead of the correct closing sequence ]]>, the sections end with a backtick (). This can result in XML parsing errors, as XML parsers expect]]>` to signify the end of CDATA sections. The fix involves detecting the presence of incorrect backticks and replacing them with the standard CDATA closing sequence.

Proposed Changes:

  1. Function to Parse Changes:

    • Update the function responsible for parsing changes, such as parse_change_log, to look for occurrences of backticks ending a CDATA section. This function should verify if a CDATA section is correctly closed.
  2. Detect and Modify Incorrect Terminators:

    • Implement logic to search for backticks in positions where a CDATA section is expected to close. Specifically, look in sections enclosed by <original><![CDATA[... and </original>, and <modified><![CDATA[... and </modified>.
    • Replace such backticks with the correct CDATA closing sequence ]]>.
  3. Reparsing of Fixed Sections:

    • Once all instances have been corrected within a single document, reparse the document to ensure the changes resolve all parsing issues and do not introduce new errors.
  4. Unit Test Suites:

    • Add test cases that simulate the erroneous input with incorrectly closed CDATA sections. Verify that the function correctly identifies and fixes these errors.
    • Include test cases for verifying that correct CDATA sections and XML structures remain unaltered.

These changes should be implemented in the part of the system managing XML parsing, focusing on the handling of CDATA sections wrapped within <original> and <modified> tags.
