In pager.c was a function: static int pagerPagecount in an #ifndef SQLITE_OMIT_WAL block. The last 3 hunks of the original patch moved the exclusion of omit_wal further down, because all sqlite databases in a new profile had zero size on OS/2 and a warning was issued from firefox that history and bookmarks won't work, because the data bases were in use by another program. >> https://bugzilla.mozilla.org/attachment.cgi?id=474575 However, this issue has been fixed already in 3.7.2 [d1ed743b6e]. (Hopefully mozilla will update to 3.7.2 soon).
The rest of the patch contained (in fossil format) in >>> https://bugzilla.mozilla.org/attachment.cgi?id=477692 is intended to explicitly disable WAL on OS/2 and bring the OS/2 related files up to date. That involves: - adding a new function, os2CurrentTimeInt64(), and refining the existing os2CurrentTime(); - adding new members to the "os2Vfs" structure, and explicitly defining them as NULL pointers since they support WAL; - updating the OS/2 semaphore documentation to match other platforms. It would be nice if these changes could be considered to get checked-in.
