| * | | | WT-2182: don't leave child refs locked; when we hit the result_entriesKeith Bostic2015-11-171-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | == 0 case in __split_parent, we will give up on the split but return 0. The cleanup path in __split_parent used to flip the child ref to WT_REF_DELETED but this branch has removed that code, and I don't think the code here can know whether the ref was unlocked. Change __split_parent to return EBUSY, but without the verbose error messages, in this case.

| | | * | | | WT-2182: we can't let newly created internal pages split until we'veKeith Bostic2015-11-133-44/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fixed up the moved WT_REF parent references. The problem is racing with other splits trying to do the same thing, we could fight over the update to the WT_REF. Add a new flag to the page that blocks splits. We can't depend on the newly created internal page's WT_REF being in a WT_REF_MEM state, there's nothing eviction from trying to evict those pages (even if they can't succeed). Change the code that fixes up the moved WT_REFs to get the page and a hazard pointer. Since we have a new page flag that blocks splits, also use the page flag to block eviction instead of setting WT_PAGE_MODIFY.mod_split_txn to UINT64_MAX (it's WT_TXN_ABORTED, which is probably a bad idea).

Instead, set the child page's mod_split_txn to a never-visible value when the child page is created, and reset it to a newly allocated transaction ID when fixing up the child pages after the split has happened.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | we could clear both skiphigh and skiplow in the search loop above, but it's not unreasonable to believe skiplow will allow us to skip some search bytes, so leave it the way it was.
