Garret Rieger a52c6df38a [subset] Fix bug in composite operation counting. 
Adding the result of add_gid_and_children to operation count over counts the number of operations.

Garret Rieger efda2f14e1 [repacker] fix bug in subgraph isolation. 
Prior to this fix id remapping at the end of the isolation operation was fed the old subgraph instead of the new one. Which results in object indices being remapped for the nodes outside of the new subgraph. Adds a test which detects this problem.

Garret Rieger 9247d24d7f [repacker] s/0/HB_TAG_NONE 2021-09-22 18:18:50 -06:00
Garret Rieger fe155de989 [repacker] handle a couple of duplication edge cases. 
- Detect cases where there are multiple links from a parent to a child. Don't duplicate that child if those are the only remaining links to the child.
- Correctly handle isolating a subgraph where the root idx has multiple incoming links.

Garret Rieger a57ef8df7e [repacker] default space to 0. 
Since vector push() init's new objects to all zeros.

Garret Rieger 58facaade1 [repacker] put each 32 bit subgraph into it's own packing space. 
Each subgraph pointed to by a 32 bit offset should be packed into it's own space. This adds a space property to vertices which affects the distance calculation. This effectively places the distances for all of the nodes of a 32 bit subgraph into a distinct range. Thus all of the nodes of the subgraph will be packed together.

Garret Rieger 543a3f9733 [repacker] Add repacker test for subgraph isolation. 2021-09-22 18:18:50 -06:00
Garret Rieger 7147f169d6 [repacker] recursively duplicate nodes during isolation. 
If a node is duplicated during isolation then any children it has will have incoming links from outside the subgraph (from the duplicated node and the original node), so they must be duplicated too.

Garret Rieger 41bbf2812e [repacker] do extension subtable isolation before starting resolution attempts. 2021-09-22 18:18:50 -06:00
Garret Rieger 8d8b7458a4 [repacker] extract overflows processing into its own method. 2021-09-22 18:18:50 -06:00
Garret Rieger b14b3f13ba [repacker] begin implementing the ability to isolate extension subtables. 
Adds isolate_subgraph operation to the repacker. This severs any links from outside a subgraph by duplicating the affected vertices. This will be used to isolate the subgraphs of a extension subtable from the rest of object graph. Thus allowing the extension subtable to be packed far away from the rest of the objects.

Qunxin Liu ca7b9daef0 [subset] subset MATH table 2021-09-22 18:08:30 -04:00
Garret Rieger c2cc566c9d [subset] Fix subset_offset_array adding unused space to serializer. 
ArrayOf.serialize_append allocates space for the new item, but ArrayOf.pop() does not recover the allocated space. So in the case where the revert path was entered the extra space added by serialize_append gets left in the serialization buffer. This moves the snapshot to before ArrayOf.serialize_append is called so that revert cleans up the buffer extend.
