Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
wrappers: improve push performance by reusing the existing metadata Push operation for n commits regenerated SVNMeta class 2*n+1 times (one time at beginning, n times in push() loop, 1 time per each of n pulls). This operation is very costly when the revision map is big. This commit reuses this metadata every time when there is no rebase made between svn commits which leads to 1 metadata rebuild in optimistic case and n+1 metadata rebuilds in pessimistic case (rebase after every commit). To achieve this I added extra parameter to pull command to pass metadata to it. All unit tests are passing for this change.
