Combine subjRequiresPage() and subjournalPage() into a single subjournalPageIfRequired() routine. (check-in: 3b65eb56 user: drh tags: trunk)
18:29
Add the PGHDR_WRITEABLE bit for PgHdr.flags which is used to distinguish between pages that are on the dirty list and pages that are safe to modify. (check-in: 7c4ef7b7 user: drh tags: trunk)
18:14
Fix over-length source code lines in pager.c. (check-in: 14de3d39 user: drh tags: trunk)

Simplifications and performance improvement in pager_write(). (check-in: ab7aeeea user: drh tags: trunk)
