I am working on a project using SQLite and I need an option enabled that is not enabled in the version installed on my Ubuntu 18.04.1 box. No big deal - I can easily grab the source and build my own version. In looking at the compile options of the installed version, I noticed that SQLite is built with the OMIT_LOOKASIDE option which changes how SQLite manages memory.

Why was this compilation option chosen?

Edited to add:

Installed version of SQLite is 3.22.0.

  • You have SQLite 2 or 3 ?

The lookaside option apparently is disabled in upstream debian package because it lead to crashes in libsqlite-3 as per bug #615061. The referenced bug report is also mentioned in the changelog of the 3.22.0-1 package version (sorry for the image of text, currently working in VM without clipboard supoprt):

  • Thanks! Was this issue ever reported back to the SQLite developers? I couldn't find it in their tracking system, but I could have missed it.

  • @user2676699 I am not aware of any such reports, but it may be worthwhile to send an email to their mailing list. I can do that, or if you want - feel free to do so. I wouldn't submit an actual bug report yet in case it already exists, though.
