Only objects reachable from the branch tips, i.e. the union of advertised branches and branches hidden by transfer.hideRefs, will be processed.

What is Full Text Search vs LIKE
...ntain the term. Full text search is optimized to compute the intersection, union, etc. of these record sets, and usually provides a ranking algorithm to quantify how strongly a given record matches search keywords.
The SQL LIKE operator can be extremely inefficient. If you apply it to an un-indexed...
What happens to a declared, uninitialized variable in C? Does it have a value?

As to what exactly indeterminate means, I'm not sure for C89, C99 says:

C char array initialization
...y way at any time in the program, provided they are members of a struct or union.

Java generics type erasure: when and what happens?
...s (Java Reference Types which are subtypeable, Any Type in many languages, Union Types).
The reason for type erasure is that programs get transformed to a language which is in some kind uni-typed (binary language only allowing bits) as types are abstractions only and assert a structure for its value...

Concurrent HashSet in .NET Framework?
...cky part about making an ISet<T> concurrent is that the set methods (union, intersection, difference) are iterative in nature. At the very least you have to iterate over all n members of one of the sets involved in the operation, while locking both sets.
You lose the advantages of a Concur...
Is the “struct hack” technically undefined behavior?
...n the above trick for getting the right size, you might also need to put a union containing every simple type before the array, to ensure that the array itself begins with maximal alignment rather than in the middle of some other element's padding. Again, I don't believe any of this is necessary, bu...
