phabsend: make --amend the default The local tag feature was intended to make `phabsend` closer to `email` workflow. But its experience is not great in multiple ways: - after rebase, obsoleted changesets are still visible because of tags - without obsstore, the association information will get lost - even with obsstore, things could go wrong with graft, export+import - no easy way to tell which Differential Revision a commit is associated Therefore make `--amend` the default. People wanting the old behavior can use `--no-amend`. Differential Revision: https://phab.mercurial-scm.org/D511

record: make the m key open an editor for the commit message (issue5667) With the former crecord extension, the user could edit the commit message while he was de-/selecting hunks. By pressing 'm', an editor showed up to edit the commit message. With record being part of mercurial, this feature is not available anymore. However, the help text still mentions it. As the infrastructure needed is still present, this feature is quite easily ported from the crecord extension to mercurial. It seems there is no test coverage for record ui, so I tested this patch manually on my local machine.

releasenotes: view admonition titles using -l flag Since this extension is fairly new for almost all the contributors, remembering the admonition (with titles) is difficult. The list (-l) flag provides a list of all the active admonitions along with titles. For usage, hg releasenotes -l returns the list. Differential Revision: https://phab.mercurial-scm.org/D454

tests: move baduisetup test inside "#if demandimport" The test case depends on the failure happening not at import time, but at uisetup() time, so it doesn't make sense when demandimport is disabled. There was already a section for testing demandimport stuff, so I moved it inside that existing section. As part of the move, I enabled the extension using '--config' so subsequent tests don't get the bad extension enabled. Differential Revision: https://phab.mercurial-scm.org/D526

revlog: abort on attempt to write null revision My repo got corrupted yesterday by something that ended up writing the null revision to the revlog (nullid hash, not nullrev index, of course). We use many extensions internally (narrowhg, remotefilelog, evolve, internal extensions) and treemanifests are on. The null revision was written to the changelog, the root manifest log, and one subdirectory manifest log. I have no idea exactly why the null revision was written, but it seems cheap enough to check that we should fail instead of corrupting the repo.

context: remove unnecessary default values for matchers (API) ctx._dirstatestatus() is called only from workingctx._buildstatus() and that function, in turn, is called only from basectx.status(). basectx.status() will always pass a matcher to _buildstatus(), so there's no need to handle a None matcher there. Differential Revision: https://phab.mercurial-scm.org/D492

run-tests: make per-line condition support testcase names 7340465bd added multiple test cases support. The latter has a problem - output lines cannot be made conditional with `#if`: ``` # COUNTEREXAMPLE: DOES NOT WORK #testcases A B $ command-foo common ouput #if A A's ouput #else B's ouput #endif common ouput ``` That's not trivial to fix (even if it works in test, `run-tests.py -i` may be suboptimal because diff algorithm does not know how to skip the `#if` lines, even if it does, it may have trouble figuring out whether a changed line belongs to inside a `#if` block or outside). Matching output lines conditionally is useful. 4eec2f04a added per-line condition support for hghave. This patch extends that to also support test case names.

run-tests: pass unicode to Pygments This is required on Python 3, and is more correct on Python 2 because Pygments is a unicode library.

run-tests: factor out highlight functions

run-tests: include "\n" in formatted message instead of calling writeln() So we don't have to strip "\n" from pygments output.

encoding: add fast path of from/toutf8b() for ASCII strings See the previous patch for why. The added test seems not making much sense because ASCII strings should never contain "\xed" and be valid UTF-8.

encoding: add fast path of from/tolocal() for ASCII strings This is micro optimization, but seems not bad since to/fromlocal() is called lots of times and isasciistr() is cheap and simple. We boldly assume that any non-ASCII characters have at least one 8-bit byte. This isn't true for some email character sets (e.g. ISO-2022-JP and UTF-7), but I believe no such encodings are used as a platform default. Shift_JIS, a major crap, is okay as it should have a leading byte in 0x80-0xff range.

encoding: add function to test if a str consists of ASCII characters Most strings are ASCII. Let's optimize for it. Using uint64_t is slightly faster than uint32_t on 64bit system, but there isn't huge difference.

encoding: add fast path of jsonescape() (issue5533) This isn't highly optimized as it copies characters one by one, but seems reasonably simple and not slow.

encoding: extract stub for fast JSON escape This moves JSON character maps to pure/charencode.py because they will be used only when the fast-path fails.

journal: do not use atomictemp (issue5338) Writing journal files using `atomictemp` leads to quadratic performance that could be problematic if automation runs many commands. Other logs like blackbox does not use atomictemp, and journal logs are not critical for repo correctness. So let's make them non-atomictemp.

tests: update test-commandserver to pass our import checker

tests: add blank output lines to test-commandserver This helps the import checker notice when a Python heredoc has ended. It's not perfect, but it gets nasty quick and I think the better fix would be to add a real parser for .t-tests, which will have to wait.

contrib: make import-checker agree more with run-tests about heredocpy run-tests.py and import-checker.py take wholly different approaches to .t-tests, and the result was that they had different notions about when a Python heredoc had ended, leading to conflicts. This resolves part of the issue, and the rest I can deal with by tweaking the one offending test file.

contrib: add bzrlib to list of packages from which we import symbols Helps some tests pass the import checker.

tests: ensure demandimport test uses absolute_import

tests: blacklist test-demandimport from test-check-module-imports It just does too much weird import stuff to have a hope of passing the checks.

tests: sort excluded test files in test-check-module-imports

contrib: allow symbol imports from hgclient for tests

tests: blacklist some more entries in module import checks

bookmarks: allow deleting active bookmark using '.'

template: add minimal obsfate template function The goal of this series is to have templates capable of displaying the evolution of a changeset in a clean and human-readable way. Add the succsandmarkers template return successors and markers so it can be used separately like this: > {succsandmarkers % "{get(succsandmarkers, "markers")|json};"} The following patches will add template functions that takes successors and markers as inputs and compute various obsfate fields from them.
