run-tests: move newline out of colorized message The leading newline before "ERROR:" led to an incorrect lexing of the message and the newline got lost. The fixed formatting can be seen in the test case. The reason we didn't notice before was that the bad formatting just led to the loss of a blank line in the test. However, there are other cases where it would be joined with a line saying "Accept this change? [n]" or "Reference output has changed (run again to prompt changes)".

test-extension: make the test compatible with chg This test fails when run with chg. This commit just makes the test chg aware by fixing the output of some of the tests. Test Plan: Ran the test 'test-extension.t' with and without '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D1160

hghave: disable demandimport when chg is running Chg disables demandimport on purpose for performance wins and therefore, it probably makes sense to indicate that demandimport is disabled when chg is running. Test Plan: Ran all the tests. Differential Revision: https://phab.mercurial-scm.org/D1161

test-show: make it compatible with chg The show extension reads `commands.show.aliasprefix` config in its `extsetup` and that causes issues with chg. This patch adds that config item to chg confighash to solve the issue. Test Plan: `run-tests.py -l --chg test-show.t` Differential Revision: https://phab.mercurial-scm.org/D1158

templater: use pycompat.sysbytes to bytes-ify some __name__ attrs Spotted by yuya in review of e87e62b7fc0b. Differential Revision: https://phab.mercurial-scm.org/D1145

templatefilters: defend against evil unicode strs in json filter We only want to do I/O in terms of bytes, so lets explode early instead of recursing forever. Differential Revision: https://phab.mercurial-scm.org/D1136

phase: use a binary phase part to push through bundle2 (BC) The part we are using for pull is now used for push too. As we no longer use pushkey, pushkey hooks are no longer triggered. This is an obvious backward incompatible change. We could artificially trigger the pushkey hook within the bundle2 part, but this seemed too hacky to me. An option would be to disable by default this new mechanism for a couple of versions to help people migrate to `txnclose-phase`. I took the liberal and optimistic path to just turn it on by default directly. .. bc:: Push no longer triggers a pushkey hook when updating phases. Use the new `txnclose-phase` and `txnclose-phase` hooks instead. (Applies when both server and client use version 4.4 or above).

arbitraryfilecontext: skip the cmp fast path if any side is a symlink `filecmp` follows symlinks by default, which a `filectx.cmp()` call should not be doing as it should only compare the requested entry. After this patch, only the contexts' data are compared, which is the correct contract. This is a corrected version of D1122. Differential Revision: https://phab.mercurial-scm.org/D1165

test-clang-format: new test to verify that files stay clang-formatted For now all .c and .h files are blacklisted. As they become clang-formatted, we'll remove them from the blacklist,and then this test will produce output if there are diffs. Differential Revision: https://phab.mercurial-scm.org/D1133

context: audit paths before clearing unknown files and dirs Fix regression introduced in D785. In some circumstances, context.clearunknown can be called before the path is audited. Audit the path before deleting any conflicting files. Differential Revision: https://phab.mercurial-scm.org/D1157
