patch: refactor file creation/removal detection The patcher has to know if a file is being created or removed to check if the target already exists, or to actually unlink the file when a hunk emptying it is applied. This was done by embedding the creation/removal information in the first (and only) hunk attached to the file. There are two problems with this approach: - creation/removal is really a property of the file being patched and not its hunk. - for regular patches, file creation cannot be deduced at parsing time: there are case where the *stripped* file paths must be compared. Modifying hunks after their creation is clumsy and prevent further refactorings related to copies handling. Instead, we delegate this job to selectfile() which has all the relevant information, and remove the hunk createfile() and rmfile() methods. [ original upstream message ]

patch: extract fs access from patchfile into fsbackend Most filesystem calls are already isolated in patchfile but this is not enough: renames are performed before patchfile is available and some chmod calls are even done outside of the applydiff call. Once all these calls are extracted into a backend class, we can provide cleaner APIs to write to a working directory context directly into the repository. [ original upstream message ]

prevent transient leaks of file handle by using new helper functions These leaks may occur in environments that don't employ a reference counting GC, i.e. PyPy. This implies: - changing opener(...).read() calls to opener.read(...) - changing opener(...).write() calls to opener.write(...) - changing open(...).read(...) to util.readfile(...) - changing open(...).write(...) to util.writefile(...)

localrepo: reuse parent manifest in commitctx if no files have changed This speeds up the in-memory version of debugbuilddag that I'm working on considerably for the case where we want to build just a 00changelog.i (for discovery tests, for instance). There are a couple of test changes because node ids in tests have changed. The changes to the patch names in test-mq-qdelete.t were required because they could collide with nodeid abbreviations and newly actually do (patch "c" collides with id "cafe..." for patch "b").
