Summary: This commit moves most of the stuff in hgext3rd and related tests to hg-crew/hgext and hg-crew/test respectively. The things that are not moved are the ones which require some more complex imports. Depends on D6675309 Test Plan: - tests are failing at this commit, fixes are in the following commits Reviewers: #sourcecontrol Differential Revision: https://phabricator.intern.facebook.com/D6675329

"""warns but doesn't exit when the user first hits Ctrl+C
|
|
|
|
This extension shows a warning the first time a user hits Ctrl+C saying the
|
|
repository could end up in a bad state. If the user hits Ctrl+C a second time,
|
|
hg will exit as usual.
|
|
|
|
By default, this behavior only applies to commands that are explicitly
|
|
whitelisted for it. To whitelist a command (say, "commit"), use:
|
|
|
|
[nointerrupt]
|
|
attend-commit = true
|
|
|
|
To change the default behavior to have all commands instrumented, set config
|
|
option ``nointerrupt.default-attend`` to true, then use the same logic to
|
|
disable it for commands where it's not wanted - for instance, for "log":
|
|
|
|
[nointerrupt]
|
|
default-attend = true
|
|
attend-log = false
|
|
|
|
Finally, to customize the message shown on the first Ctrl+C, set it in
|
|
config option ``nointerrupt.message``.
