Hello ! I understand the original point of view of this thread, but I'm glad that we have those submissions here because it makes me aware of people/tools/technics/patterns that can help in other projects. Cheers ! On 6/1/20 15:44, Simon Slavin wrote: On 6 Jan 2020, at 2:40pm, Yongheng

Re: [sqlite] A hang in Sqlite

Will sending bugs to b...@sqlite.org open a ticket in here? (https://www.sqlite.org/src/rptview?rn=1 ) If yes it works for me. If not since many of the bugs we reported are silently fixed, it will be difficult for us to keep

Hi, I am sorry if I was polluting the mail list. As nobody mentioned that before and reporting bugs to this mail list is what is said in the official website, I just keep doing this. I think Manuel has the access to open a ticket. Could I be granted this access too so that I don’t need to send

Hello everybody, What is fuzzer sql ? Is it some sort of random sql generator ? How do they create that non sensical yet syntactically correct SQL ? Just curious. Regards Noël On Mon, 6 Jan 2020 at 15:14, Dominique Devienne wrote: > On Mon, Jan 6, 2020 at 2:36 PM Jose Isaias Cabrera > wrote: >
