[Qemu-devel] [PULL] check-qjson: More thorough testing of UTF-8 in strings |
|
Date: |
Thu, 21 Feb 2013 15:19:40 -0300 |
From: Markus Armbruster <address@hidden>
Test cases are scraped from Markus Kuhn's UTF-8 decoder capability and
stress test at
http://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-test.txt
Unfortunately, both JSON parser and formatter misbehave right now.
This test expects current, incorrect results. They're all clearly
marked, and are to be replaced by correct ones as the bugs get fixed.
See comments in new utf8_string() for details.

+ * FIXME Current behavior for invalid UTF-8 sequences is
+ * incorrect. This test expects current, incorrect results.
+ * They're all marked "bug:" below, and are to be replaced by
+ * correct ones as the bugs get fixed.
+ *
+ * The JSON parser rejects some invalid sequences, but accepts
+ * others without correcting the problem.
+ *
+ * The JSON formatter replaces some invalid sequences by U+FFFF (a
+ * noncharacter), and goes wonky for others.
+ *
+ * For both directions, we should either reject all invalid
+ * sequences, or minimize overlong sequences and replace all other
+ * invalid sequences by a suitable replacement character. A
+ * common choice for replacement is U+FFFD.
+ *
+ * Problem: we can't easily deal with embedded U+0000. Parsing
+ * the JSON string "this \\u0000" is fun" yields "this \0 is fun",
+ * which gets misinterpreted as NUL-terminated "this ". We should
+ * consider using overlong encoding \xC0\x80 for U+0000 ("modified
+ * UTF-8").
+ *
+ * Test cases are scraped from Markus Kuhn's UTF-8 decoder
+ * capability and stress test at
