Hi Thomas (and list), I have run into what appears to be a limitation with [pool], namely that it crashes with something around ~780 characters loaded from a file as values in a key.
I ran into this loading a particularly long list in Memento. I've attached a patch and a file from which to load to experience the crash. The file is just a little over the character count needed to crash it (it seems to be between 780 and 800?). It does not seem to be a function of the number of elements in the list, but rather the length of the text in those elements. Shorten a few of the values in the list and it loads right up.
I'm also pretty sure this is a per-key limitation, as memento's lddir first loads files into /tmp before copying them into the proper key. I've used that with a file that was just under the crashing length and that worked fine (loaded into two keys).
I have tested this on both my PPC Mac and my Intel Mac; maybe others can check it out too?
(also to clarify, the problem occurs when loading data from a file; data of any length (that I've tried) makes it into the pool without issue, and saves without issue)
Thanks! Luke
Oh, and I forgot to mention... after leaving it for a while on my G5, the console started to fill with messages like so: "pool - format mismatch encountered, skipped line 40074" with an ever increasing line number.
I left it for about 10 minutes after that began and it showed no sign of stopping.

Hi Luke,
thanks for the report.
It's a typical buffer overrun (caused by a loooong line of data),
making quick-and-dirty code choke.
I hope to fix it shortly, please stand by!
greetings, Thomas

Great! Hope it is not too painful : ) Thanks! Luke On 5/9/07, Thomas Grill gr@grrrr.org wrote:

Hi Thomas,Don't suppose you ever figured this out? Cheers Luke
