Minor item...I reported this before...
Compiling version 3.7.5...this warning has actually been around a while though
I can't find anybody reporting it for sqlite3...
gcc44 -O3 -Wall -fPIC -DNO_GETTOD -c sqlite3.c
sqlite3.c: In function âfkLookupParentâ:
sqlite3.c:55430: warning: assuming signed overflow does not occur when assuming
that (X - c) <= X is always true
gcc44 (GCC) 4.4.0 20090514 (Red Hat 4.4.0-6)
Compile with -O1 and no warning
Compile with gcc 4.1.2 and -O3 and no warning either
Appears the new optimization causes this...
If I change the line to this the warning goes away:
if( (unsigned int)p->nOp>(unsigned int)addr){
Since these appear to be used as unsigned values anyways this looks like a
valid way to supress the warning.
Would also appear to need a
assert( p->nOp>=0 );

Subject: EXTERNAL:[sqlite] SQLite version 3.7.5 - code freeze
The current plan is to release SQLite version 3.7.5 on Wednesday of next
week 2011-02-02. Please see draft release notes here:
http://www.sqlite.org/draft/releaselog/3_7_5.html
You can download a snapshot of the latest SQLite amalgamation from here:
http://www.sqlite.org/draft/download.html
Unless serious problems or omissions are found, there will be no further
code changes prior to the release of version 3.7.5, except to address
whatever minor documentation errors, compiler warnings, or other nuisance
issues that come up during release testing.
Your help in identifying potential problems prior to the release of version
3.7.5 is appreciated. Please download and test the snapshot shown above in
your applications and let us now (quickly) of any issues you encounter.
As soon as version 3.7.5 is released, our plan is to merge in several other
changes that currently reside in branches of the source three:
* A blocking version of PRAGMA wal_checkpoint that guarantees that the
WAL file will reset
* Enhancements to the foreign-key checking logic
* Enhancements to the query planner
I'll be asking you to download and test new snapshots after these merges
occur in early February. But for now, we want version 3.7.5 to be very
stable, so please do test as soon as you can and give us feedback right
away.
Thanks!
