test: don't trust delta bases from the bundle in test-sparse-revlog.t The point of the test is to check the strategy sparse-revlog uses to pick delta base. If we trust the bases used in the bundle, we no longer fully test this logic. In order to force this computation we have to use the side effect of a legacy format configuration `format.generaldelta`. The lack of a more official way to do so will be fixed in a later changeset.

test: update test-sparse-revlog.t output This test is skipped unless a large artefact is pre-build. It seems like nobody ran it in a while. Changeset 3764330f76a6 changed the expected output but nobody noticed. This changeset focus on the first and simpler step: putting the expected output back to what one would get by running this test. However this test changes highlight a couple of deeper issues: 1) Even if the revision content did not changed, a change in the delta contained in the bundle affected the delta stored in the final revlog, changing the test result. Since we are testing the delta computation strategy with sparse, we should not blindly reuse the delta-base from the bundled delta. 2) A change in the format of the repository used to generate the bundle changed the delta stored in the bundle. We should get a more stable output to avoid future instabilities of this test. 3) The test is it not run by CI or developer. We'll try to address all this issues in the coming changesets.

mq: disable qrecord during histedit (issue5981) qrecord during histedit may lead to deadlock-like situations. qpop will throw an error on called during histedit even after qrecord-ing those changes. This patch makes qrecord to abort on histedit. Differential Revision: https://phab.mercurial-scm.org/D5997

committablectx: move status-related methods closer together The modified()/added()/removed()/deleted() clearly belong very close to status(). I separated them in committablectx by the new p[12]copies() methods. This brings the close again. Sorry about the churn. Differential Revision: https://phab.mercurial-scm.org/D5996

tests: add test for hg-test-mode emacs code This is just coverage for the compilation-mode support, but that was enough of a hassle that I wanted to have it covered somehow. Test methodology is _extremely_ cargo-culted from the test for compilation-mode in emacs, so I still have no idea what I'm doing. Differential Revision: https://phab.mercurial-scm.org/D6003

contrib: also linkify tracebacks in compilation output when using hg-test-mode Differential Revision: https://phab.mercurial-scm.org/D6001

contrib: add compilation-mode linking for our test output These regular expressions will cause compilation-mode buffers in emacs to link to source when there are check-code errors in the output of a .t test. In the true tradition of this file, I also have no idea what I'm doing. Differential Revision: https://phab.mercurial-scm.org/D6000

diff: make sure we output stat even when --git is not passed (issue4037) (BC) Before this patch, `hg diff --stat` will give an empty output. It will not show the stat information. I debugged and found that the underlying code does not return the diff header and due to that, other code paths fails to parse that as a diff. I looked into why we don't return diff headers in quiet mode and found the behavior is from 8f8bb77d560e70bcc95577e4dfa877df18d876ab which does not have any mention about why it is done. We also show the diff headers in git, so I think it's fine showing diff header in normal diff in quiet mode. Differential Revision: https://phab.mercurial-scm.org/D6007

tests: add test to demonstrate issue4037 `hg diff --stat -q --config diff.git=0` does not output anything whereas it should print the stat. This is a quiet old bug dating to 2013 and looking at code I think it exists it since 2005 or when --stat was introduced. The next patch will fix the bug.

grep: reuse getrenamedfn() from scmutil My motivation is to reduce uses of filectx.renamed(). Reusing scmutil.getrenamedfn() also means that we get some caching of copy information per file and revision. I don't think that matters for `hg grep` (I doubt it speeds up significantly, and I doubt it wastes significant memory), but I'm not sure. Differential Revision: https://phab.mercurial-scm.org/D6022

templatekw: move getrenamedfn() to scmutil (API) The function is already used by `hg log` (for following renames, not for templates), so it seems it does not belong in templatekw. Differential Revision: https://phab.mercurial-scm.org/D6021
