pathutil: use temporary variables instead of complicated wrapping The one-lining did not help readability, we get rid of it.

context: use a the nofsauditor when matching file in history (issue4749) Before this change, asking for file from history (eg: 'hg cat -r 42 foo/bar') could fail because of the current content of the working copy (eg: current "foo" being a symlink). As the working copy state have no influence on the content of the history, we can safely skip these checks. The working copy context class have a different 'match' implementation. That implementation still use the repo.auditor will still catch symlink traversal. I've audited all stuff calling "match" and they all go through a ctx in a sensible way. The most unclear case was diff which still seemed okay. You raised my paranoid level today and I double checked through tests. They behave properly. The odds of someone using the wrong (matching with a changectx for operation that will eventually touch the file system) is non-zero because you are never sure of what people will do. But I dunno if we can fight against that. So I would not commit to "never" for "at this level" and "in the future" if someone write especially bad code. However, as a last defense, the vfs itself is running path auditor in all cases outside of .hg/. So I think anything passing the 'matcher' for buggy reason would growl at the vfs layer.

localrepo: add a second auditor without file system check Auditors keeps a cache of audited paths. Therefore we cannot use the same auditor for working copy and history operation. We create a new one without file system check for this purposes.

pathauditor: add a way to skip file system check We need to be able to skip it when looking at data within the history. Doing them in all cases leads to buggy behavior like issue4749.

pathauditor: move file system specific check in their own function This will make it easy to disable that part when not relevant (eg: auditing filename for operation in history)

contrib: disable SSLv3_method() to build old Python with recent libssl Because OpenSSL is compiled without SSLv3 support on Debian sid, Python 2.6.9 can't be built without this hack. Python 2.7 is patched appropriately, but 2.6 isn't. http://bugs.python.org/issue22935

rebase: only clear rebase status after the rebase transaction has completed In 405320cd6198, I made the mistake of moving the step "clearing the status after a rebase" to inside the rebase transaction. This was wrong, since we don't want to clear the status (and the rebase state) if something went wrong during the transaction: if something goes wrong we want to keep the rebase state to be able to abort. It broke rebase with evolve + inhibit.

dirstate: don't write repo.currenttransaction to repo.dirstate if repo is None (issue4983) Some hooks, such as post-init and post-clone, do not get a repo parameter in their environment. If there is no repo, there is no repo.currenttransaction(); attempting to retrieve it anyway was causing crashes. Now currenttransaction is only retrieved and written if the repo is not None.
