hgweb: correct an earlier error of mine - `start` should be bytes Gets hgweb very close to working with Python 3. Differential Revision: https://phab.mercurial-scm.org/D1134

config: simplify aliasing commands.update.check experimental.updatecheck was renamed into commands.update.check, use the config system to provides the fallback on the old config name instead of adding more code. Differential Revision: https://phab.mercurial-scm.org/D1117

run-tests: set HGPLAIN=1 when bisecting Otherwise a customized template may break the regex matching the bisect output. Differential Revision: https://phab.mercurial-scm.org/D949

run-tests: extract Popen logic to a single method This removes 3 lines in total LOC and makes the upcoming changes easier. Differential Revision: https://phab.mercurial-scm.org/D948

run-tests: move bisect logic to a separate method This removes 8 space indentation and makes upcoming changes easier. Differential Revision: https://phab.mercurial-scm.org/D947

mpatch: switch alignment of wrapped line from tab to spaces with clang-format I may be a weird person for liking this style, but our C style is historically nominally the Linux Kernel style, and when you configure clang-format to be kernel-ish, this is what you get. If we want to change it, we can do so by tweaking the formatter rules in the future. Differential Revision: https://phab.mercurial-scm.org/D1132

mpatch: reformat function prototypes with clang-format Differential Revision: https://phab.mercurial-scm.org/D1131

contrib: remove check-code rule about indentation We're moving towards a clang-format world, and clang-format is able to wrap argument lists with spaces reliably, while still enforcing tabs globally. Let's let clang-format do its job, and not do as much C-style enforcement with regular expressions. Differential Revision: https://phab.mercurial-scm.org/D1130

merge: allow user to halt merge on merge-tool failures Depends on D932. Call the new _onfilemergefailure function when a merge tool reports failure via a return code. Differential Revision: https://phab.mercurial-scm.org/D951

filemerge: introduce functions to halt merge flow Depends on D931. This patch introduces functions and a config option that will allow a user to halt the merge if there are failures during a file merge. These functions will be used in the next patch. Differential Revision: https://phab.mercurial-scm.org/D932

amend: add a flag `-n/--note` to store note with amend This patch utilises the functionality added in previous patches and adds a flag to amend command in hgext/amend to add a note to the amend. Since the note is stored in the obsmarker metadata, this will only be useful when obsmarker creation is enabled, otherwise this is no-op. Not adding releasenotes part as we yet don't have a functionality in core to show the note. Differential Revision: https://phab.mercurial-scm.org/D1095

cmdutil: pass metadata from amend() to cleanupnodes `commit --amend` and amend command in core and extensions rely on cmdutil.amend() for amending a commit. So the logic to add a note to amend must reside here. This patch assumes that note will be passed in opts dictionary to the function and it will be passed to cleanupnodes and then createmarkers to store the note in the obsmarker metadata. After this patch, note can be stored on an amend changeset by passing notes as a part of opts to cmdutil.amend(). Differential Revision: https://phab.mercurial-scm.org/D1094

scmutil: add capability to cleanupnodes to take obsmarker metadata This patch adds a metadata argument to cleanupnodes() which will be dict and can be passed to obsmarker.createmarkers() and can be stored on the obsmarker. In cases when obsolescence is not enabled, the metadata argument is useless. This is a step towards storing a note in amend. Differential Revision: https://phab.mercurial-scm.org/D1093

test-hgweb-annotate-whitespace: make test compatible with chg D946 fixed a bunch of tests which had the same root cause. Please see that for details. This seems to be one of the newer tests which fails because of the same reason. Test Plan: Ran the test 'test-hgweb-annotate-whitespace.t' with and without the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D1124

test-pager: make the test compatible with chg D911 tried to make this test compatible with chg but instead resulted in the test being flaky for chg. For now, disabling this test for chg because it seems difficult to fix the test. This will allow for the continuous build setup for chg. Test Plan: Ran the test 'test-pager.t' with and without the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D1128

test-obsolete-bounds-checking: make the test compatible with chg This test fails when run with chg because the error message starts with "ProgrammingError" instead of "mercurial.error.ProgrammingError". Therefore, globing the "mercurial.error." to ensure that the test is compatible with chg. Test Plan: Ran the test 'test-obsolete-bounds-checking.t' with and without the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D1127

test-dispatch: make the test compatible with chg The test is broken when run with chg because it prints a different error message when chg is running. This commit fixes the test by special casing for chg. Test Plan: Ran the test 'test-dispatch.t' with and without '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D1126

histedit: remove the nonexistant config 'histeditng' D942 removed the experimental config 'histeditng'. This is a leftover which should have been removed in that commit. Therefore, this commit completes the cleanup. Test Plan: Ran all the tests. Differential Revision: https://phab.mercurial-scm.org/D1123

context: add workingfilectx.markcopied With in-memory merge, copy information needs to be stored in-memory, not in the dirstate. To make this transition easy, move the existing dirstate-based approach to workingfilectx; that way, other implementations can choose to store it somewhere else. Differential Revision: https://phab.mercurial-scm.org/D1106

filemerge: use arbitraryfilectx for backups With in-memory merge, backup files might be overlayworkingfilectxs stored in memory. But they could also be real files if the user's backup directory is outside the working dir. Rather than have two code paths everywhere, let's use arbitraryfilectx so they can be consistent. Differential Revision: https://phab.mercurial-scm.org/D1057

registrar: add support for storing the type of command in func object This patch adds support for storing the type of command which is going to run in the func object. For this it does the following: 1) Add three possible values as attributes to the registrar.command class 2) Add a new argument to registrar.command._doregister function 3) Add a new attribute cmdtype to the func object The type of command will be helpful in deciding what level of access on hidden commits it can has. Differential Revision: https://phab.mercurial-scm.org/D736

releasenotes: fix documentation of similaritycheck() The function document says that it returns true when the fragment can be merged, but if you see the function just above it which is similar(), it writes already exists thing if return value from similaritycheck() is False which is just opposite of the doc. This patch fixes that. Differential Revision: https://phab.mercurial-scm.org/D1119
