test-compat: merge stable into mercurial-4.3

Added tag 6.8.0 for changeset ec0bbf26ce7f

packaging: prepare version 6.8.0

flake8: rename some ambiguous identifier Apparently, pyflakes declared war on 'l'.

topic: instroduce a fast path when computing stack We do some stack related computation during transaction now. The current inefficiency of the revset is hurting us too much. We pre-compute a subset using native set operation to speed things up.

branching: merge stable back into default

test-compat: merge future 6.7.0 in mercurial-3.8 branch

test-compat: merge future 6.7.0 in mercurial-3.9 branch

test-compat: merge future 6.7.0 in mercurial-4.0 branch

test-compat: merge future 6.7.0 in mercurial-4.1 branch

test-compat: merge future 6.7.0 in mercurial-4.2 branch

test-compat: merge future 6.7.0 in mercurial-4.3 branch

obsfate: re-enables operation display in obsfate Now that the compatibility checks are in a good shape we can re-enable more noise in it.

changelog: update to reflect latest change

test-compat: merge with mercurial-3.9 branch

test-compat: merge with mercurial-4.0 branch

compat-test: remove topic related tests for 3.9 The extension is no longer supported for 3.9

test-compat: merge with mercurial-4.1 branch

test-compat: merge with mercurial-4.2 branch

test-compat: merge with mercurial-4.3 branch

branching: merge with mercurial-4.3 branch creation The other changeset marks the point were 'stable' is no longer about Mercurial version 4.3.

test-compat: revert output changes from phase renaming We keep using the old name for the older version. test has to reflect that.

test-compat: revert output changes related to temporary amend commit This backed out changeset 06844693bb21 and other related changes.

test-compat: revert ouput change to blackbox This backed out changeset 86be70ae38b9.

test-compat: revert ouput related to operation This effectively backs out 4b951a9a6895.

test-compat: revert output change in rebase This backed out changeset d12c82fd1143 and a couple of other changes. The change are not relevant in Mercurial < 4.4/

test-compat: revert output change from bundle2 capability This backout changeset dd3eda2f7a89 not relevant for verison < 4.4.

test-compat: revert output change on pull report The revert the changeset from 8feb2cae7eae. Not relevant for verison < 4.4.

test-compat: revert output change from 'phase' part The output change were introduced in changeset from 87e349f617f9 and it not relevant for version lower than 4.4.

test-compat: revert output change from using core obsfate The output update arrives in e91ca8b5ecf7. This output is only relevant for Mercurial 4.4

topic: do to check to topic while amending Right know the 'topic-mode' mess with amend. Especially in case of amending merge where the merge is not properly detected.

topic-mode: add missing end line in topic-mode warning

compat: work around the lack of configoverride in mercurial 4.0 The phase preservation will stay broken on 4.0 and below

compat: add an abstraction for 'scmutil.cleanupnodes' The usage of the function was added in 103244e34a9c but is not compatible with Mercurial <= 4.2.

compat: conditionally access config item Version 4.2 and below do not have config items support. So the extensions helper do not register anything.

compat: handle version where obsutil is not available Version older than 4.3 is do not have the obsutil option. We need to handle that.

test: use node instead of rev in topic push tests This makes the test more stable when revision number changes.

test: use node instead of rev in uncommit -i test This makes the test more stable when revision number changes.

branching: create the mercurial-4.3 test compatibility branch This branch will contains the expected test output with 4.3.

branch: merge with stable to prepare 6.7 release In addition, Mercurial 4.4-rc is out, so we need to update the expected output.

changeloge: add details about topic-mode

effect-flag: remove wrapping of createmarkers for Mercurial 4.4 Now that effect-flag has landed in Mercurial 4.4, we don't need to wrap createmarkers for this version anymore.

stack: order the adjective of changeset The new order give more interesting result: * base current * base unstable * current unstable It seems more harmonious this way. Base seems the most core and immutable adjective describing the element. Then current is a volatile but important one. Finally, unstable is less information than current, so it goes last.

stack: show current and unstable also for t0 and bases

obsfate: use core version of obsfate if available Let us use the upstream version whenever available. The operation display is currently disabled to ease with the test changes.

topic: register config items There is a couple more hoops to jump through but all config items used are now registered.

directaccess: register config item if possible Mercurial 4.4 warns about unregistered config.

evolve: registed configitems if available The config are registered as 'dynamicdefault' because we still need to explicitly pass the config option for older version of Mercurial. (4.2 and before).

inhibit: compatibility with 4.4-rc

branching: merge with stable Merge with the inhibit fix.

inhibit: respect '--keep' when handling rebase clean up

test: adapt to change from 537de0b14030 If we use phase for pull/push this impact some debug output. CORE-TEST-OUTPUT-UPDATE: 537de0b14030

test: adapt to output change from eb586ed5d8ce Core have a more verbose output on pull. We have to update tests with it. CORE-TEST-OUTPUT-UPDATE: eb586ed5d8ce

compat: fix compatibility with new duplicatecopies Changeset 754b5117622f updated the signature of 'copies.duplicatecopies'. We can now handle the multiple version of that code for compatiblity.

topic: remove 'ass' from the random animal list As much as I love donkey… this generate inappropriate names.

config: stop passing useless default value to config

branching: merge with stable

changelog: add about fixed bookmark and phase handling while changing topics

changelog: add about pager support

pager: add support to `hg evolve --list`
