6 check-ins going from d4d9869c30710914 to fb7f094e4e0f0362

2021-06-16
11:32
Enhanced defense against integer overflow in ALTER TABLE. (check-in: fb7f094e4e user: drh tags: trunk)
2021-06-15
20:10
Fix some #ifdefs so that builds work for all supported compile-time options. (check-in: ca7d78f781 user: drh tags: trunk)
15:36
Update the "nmakehlp.c" utility program sources associated with the TCL Extension Architecture, obtained from https://core.tcl-lang.org/sampleextension/file. Perhaps this new version will sit better with salmonx's static analyzer (ref1), (ref2). (check-in: 603b851d7d user: drh tags: trunk)
15:15
Add NULL checks on all sqlite3_vfs_find(0) calls. This is not strictly necessary. There are no vulnerabilities here. However, adding these checks avoids unnecessary static analyzer complaints. Forum post ce1193be15. (check-in: 272a15b9f4 user: drh tags: trunk)
14:34
Prevent an infinite loop in the trim() SQL function if the second argument is a carefully malformed UTF8 string. (check-in: 829343c26e user: drh tags: trunk)

20:49
Fix typos in testcase() macros from check-in [c09d90eec2a49b94]. (check-in: d4d9869c30 user: drh tags: trunk)
