You could certainly put together a bash script to compare the tags generated by this list with the tags you have locally. Take a look at git show-ref --tags, which generates the ...
Array versus linked-list
...
@Rick, vectors typically overallocate the space they require so that they don't need to allocate new space everytime the size increases. The result is that vectors are typically much less memory intensive, not more then linked lists.

char *result = malloc(strlen(s1) + strlen(s2) + 1); // +1 for the null-terminator

Using arrays or std::vectors in C++, what's the performance gap?
...rator is the same damn thing as
// incrementing a pointer.
Note: If you allocate arrays with new and allocate non-class objects (like plain int) or classes without a user defined constructor and you don't want to have your elements initialized initially, using new-allocated arrays can have perfor...
Differences between std::make_unique and std::unique_ptr with new
...untime efficiency the way using make_shared does (due to avoiding a second allocation, at the cost of potentially higher peak memory usage).
* It is expected that C++17 will include a rule change that means that this is no longer unsafe. See C++ committee papers P0400R0 and P0145R3.

How do I clear the std::queue efficiently?

RDFC is probably not the fastest, but it does allocate data blocks. The absolutely fastest would have to use lower level API to just obtain cluster chains and put them into MFT without writing data.
Beware that there's no silver bullet here - if "creation" returns insta...
