You should check out the code and use Fossil (the SQLite source code control tool). That way you will be using the same source and files as the authors. You'll also be able to keep up to date with their changes. See the very bottom of http://sqlite.org/download.html This will also allow you to work with the test suite and add your own tests. Your code changes won't actually be useful if they break things! > * Where are pages read and written? I found the page-cache, but not > the functions that read/write those pages to disk.

When you work on the real SQLite source you'll find pager.c and pcache.c.

[sqlite] How is the page-cache filled?
Hi, I would like to create a version of sqlite, which includes a few changes to the way pages are loaded and written to disk. * Which version of the source should I use? The amalgamized source isn't really useful, however for all other source-archives its stated its not recommended using. * Where are pages read and written? I found the page-cache, but not the functions that read/write those pages to disk. A small hint would be really helpful :) Thanks a lot, Clemens ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
