问题
Is there a way to "hijack" a file in subversion like there is in ClearCase. Googling so far has not given me a definitive answer. For non ClearCase users Hijacking a file means temporarily removing it from version control.
回答1:
SVN operates on a "copy-modify-merge" model, meaning it's always possible to make local modifications to your working copy, without needing to "lock" or "hijack" it.

回答2:
ClearCase has an odd mix of optimistic lock and pessimistic lock.
But hijacking a file (for snapshot view) or eclipsing a file (for dynamic view) concerns only private changes (i.e. changes done without telling ClearCase first).
As David mentions, SVN doesn't follow that model: you modify first, and then tell SVN during the commit step, which will include all files modified.
ClearCase has not a "workspace wide revision", only a file-by-file commit.
