Using YapDatabaseViewMappings with fixed range

[ERussel]

I think i found a bug when used YapDatabaseViewMappings with fixed range. When i received notification about changes my app just freeze. I found out that the problem in method + (void)postProcessAndFilterRowChanges:(NSMutableArray *)rowChanges
withOriginalMappings:(YapDatabaseViewMappings *)originalMappings
finalMappings:(YapDatabaseViewMappings *)finalMappings.

It has cycle by groups and inner cycle where range applies to changes, but when group from outside cycle is not equal to first group in rowChanges array then we get infinite loop.

Second bug:

1. Create mapping for UITableView using initWithGroupBlock:sortBlock:view.
2. Implement sorting by comparing first objects of groups.
3. Create fixed range for every group to show only first object.
4. For example, we have 2 groups A and B. And on start we see first section for A group then for B.
5. Insert object to the group B in such way to reorder sections in table view
6. In result, generates 2 row changes: insert change for first section and delete for second section.

But it should be both changes for first section. It happens because insert change gets right final section and delete change wrong one(because gets it from original mapping).

I think i found a bug [in] postProcessAndFilterRowChanges:::

This is a really big method (~ 1,200 lines), and I'm having difficulty pinpointing the section of code you're referring to. Could you provide more information? Perhaps line numbers?

[ERussel]

The line number is 1390. There we have a cycle(while) where range applies to changes and when the state on line 1394 is not true then we fall into infinite loop.
