upgrade: import 'localrepo' globally
The in-function imports mention a cycle that seems to no longer be relevant. As
a result, we just import it globally.
largefiles: set the extension as enabled locally after a share requiring it
This has been done for clone since
e1dbe0b215ae, so it makes sense here for the
same reasons.
windows: add context manager support to mixedfilemodewrapper
I stumbled into this in the next patch. The difference between getting a
context manager capable object or not from vfs classes was as subtle as adding a
'+' to the file mode.
chg: always wait for pager
Previously, when runcommand raises, chg aborts with, and does not wait for
pager. The call stack is like:
hgc_runcommand -> handleresponse -> readchannel -> debugmsg("failed to
read channel") -> exit(255)
That means, chg returns to the shell, then both the pager and the shell will
read from the terminal at the same time, causing problems.
This patch fixes that by using "atexit" to register the pager cleanup
function so chg will always wait for pager even if runcommand raises.
bundle2: move 'seek' and 'tell' methods off the unpackermixin class
These methods are unrelated to unpacking. They are used internally by the
'unbundlepart' class only. So me move them there as private methods.
In the same go, we clarify their internal role in the their docstring.
shelve: rename nodestoprune to nodestoremove
