So LMX is supposed to be able to take data in chunks, from the end of the file. It turns out that this doesn't work if a chunk breaks up an entity, though.
A chat transcript, submitted by lhirlimann to me via email by request, exhibits this behavior on my machine, when read by -[DCMessageContextDisplayPlugin contextForChat:], since that method reads in 4*getpagesize() byte chunks and that number of bytes from the end is the middle of an entity. Specifically, the resulting chunk #1 starts with 'apos'. The resulting chunk #2 ends with '&'. The result is an assertion failure: *** Assertion failure in -[LMXParser parseEntityReference:], /Volumes/Huffman/Projects/lmx-sholt/LMXParser.m:605 "entity name was empty! currentIndex is 5193 (&) out of 21579 bytes" It's not clear to me how to proceed with a fix. Do you (yes, you!) have any ideas? I don't want to post the user's chat log to a public mailing list; if you're an existing developer and would like it in order to easily see the behavior, email me off-list. This took way too long to hunt down, though it's a fairly obvious problem in retrospect. Cheers, Evan
