Any other information unique or specific to your setup:
We are custom compiling sqlite3 extension. For compilation we followed
following steps:
1. Download php source code.
2. Download latest sqlite3 source code.
3. Copy latest sqlite files to ext/sqlite3/libsqlite/ folder.
4. Call phpize and then configure with following flags -DHAVE_READLINE
-DNO_TCL -DSQLITE_THREADSAFE=1 -DSQLITE_ENABLE_FTS3_PARENTHESIS
-DHAVE_USLEEP=1-DSQLITE_ENABLE_FTS3=1.
5. Call make and copy the destination sqlite3.so to our svn folder.
6. Using some deployment script destination sqlit3.so gets copied to php
extension_dir on other machines.
Also,We are doing a custom session handling using
session_set_save_handler function.
