evolution: rename trouble(s) to instability Rename trouble(s) to instability in all external user-facing output. Only update user-facing output for the moment, variables names, templates keyword and potentially configuration would be done in later series. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary. Differential Revision: https://phab.mercurial-scm.org/D213

bundle2: load hookargs from bundleoperation into transaction when started one When a transaction is started, we must load the hookargs from the bundleoperation object to the transaction so that they can be used in the transaction. Also this patch makes sure no more hookargs are added to the bundleoperation object once the transaction starts. This is a part of porting fb extension bundle2hooks to core.

bundle2: add the capability to store hookargs on bundle operation object There are extensions like pushrebase, pushvars which run hooks on a server before taking the lock. Since the lock is not taken, transaction is not there, so the hookargs can't be stored on the transaction. Adding hooksargs to bundle operation object will help in running hooks before taking the lock. This is a part of moving fb's extension bundle2hooks to core.

branchmap: revert c34532365b38 for Python 2.7 compatibility Old versions of python 2.7 don't like that the second argument to struct.unpack_from is a bytearray, so the change removing the util.buffer around that argument in branchmap broke running on older versions of python 2.7.

Added tag 4.3.1 for changeset 3fee7f7d2da0

ssh: unban the use of pipe character in user@host:port string This vulnerability was fixed by the previous patch and there were more ways to exploit than using '|shellcmd'. So it doesn't make sense to reject only pipe character. Test cases are updated to actually try to exploit the bug. As the SSH bridge of git/svn subrepos are not managed by our code, the tests for non-hg subrepos are just removed. This may be folded into the original patches.

ssh: quote parameters using shellquote (SEC) This patch uses shellquote to quote ssh parameters more strictly to avoid shell injection.

subrepo: add tests for git rogue ssh urls (SEC) 'ssh://' has an exploit that will pass the url blindly to the ssh command, allowing a malicious person to have a subrepo with '-oProxyCommand' which could run arbitrary code on a user's machine. In addition, at least on Windows, a pipe '|' is able to execute arbitrary commands. When this happens, let's throw a big abort into the user's face so that they can inspect what's going on.

push: add tests for unsafe ssh url (SEC)

pull: add tests for unsafe ssh url (SEC)

clone: add tests for unsafe ssh url (SEC)

sshpeer: check for safe ssh url (SEC) Checking in the sshpeer for a rogue ssh:// urls seems like the right place to do it (instead of whack-a-mole with pull, clone, push, etc).
