New submission from Джон Смит <kiberti...@gmail.com>: Data is lost when parsing large files. I have prepared 5 test files for different cases. With their help, I learned that losses are not accidental. In example.xml, when going to iteration 717 (i = 717), the data is lost.
In the rest of the files, I learned that data loss occurs when the number of characters changes. It looks like some kind of buffer overflow. In example5.xml I am using randomly generated data using a generator.py. Several xml files have been prepared to show that this is not an error in the input data, but a problem in the library itself. I tried to trace the cause of the occurrence, and came to the conclusion that the bug lies in the compiled file. In the ElementTree.py library file, the line "events = self._events_queue" returns an empty list. This can be seen at iteration 717 in example.xml. ---------- components: XML messages: 377928 nosy: kibertitan priority: normal severity: normal status: open title: Unpredictable behavior when parsing xml.
