shelve: no longer strip internal commit when using internal phase When the internal phase is used, the internal commits we create during shelve will be automatically hidden, and we don't need to strip them. Avoiding strips gives much better performances and is less traumatic for caches. Test changes are all related to revision numbers increasing more quickly since we avoid stripping. At the end of `test-shelve.t` we now need manually strip the shelve-commit in addition to the x.shelve file deletion. This emulates a preexisting shelve after a repository upgrade. Note: The hidden internal commits confuses rebase a bit as shown by a new test added. This will happen when the user have shelve commits on top of a changeset to be rebased. We'll fix this in the next commit. As we still use a backup bundle, rebase can just strip the internal changesets and be fine.

meld: enable auto-merge This tells meld to resolve trivial conflicts before presenting the user with the remaining conflicts. This was attempted 5 years ago, but then --auto-merge was too new that the patch was rejected out of concern that users still had an older version of meld installed [1]. Maybe it's safe to assume that they have a newer version now.

run-tests: partially backout PYTHON quoting In 7f8b7a060584, I quoted this to support python being installed to "Program Files". Even though the string passed to os.popen() is this: "c:/Python27/python.exe" -c "import mercurial; print (mercurial.__path__[0])" ... cmd.exe is trying to run this: 'c:/Python27/python.exe" -c "import' This caused test-hghave.t to fail, reporting 'unexpected mercurial lib: ""', because the failed execution prints nothing to stdout. Py3 fails as though it's not quoted. For whatever reason, print() shows up in the output when run with py2, but not py3, so I'm having a hard time debugging this. For now, let's fix the buildbot.

py3: use '%d' instead of '%s' for integers Python 3 does not allow to use '%s' for integers. Differential Revision: https://phab.mercurial-scm.org/D4688

chgserver: restore pager fds attached within runcommand session While rewriting chg in Rust, I noticed the server leaks the client's pager fd. This isn't a problem right now since the IPC process terminates earlier than the pager, but I believe the fds attached within a "runcommand" request should be released as soon as the session ends.

chgserver: add separate flag to remember if stdio fds are replaced I want to make it use a separate saved buffer for "attachio" requests within "runcommand" session. See the next patch for details.

status: remove "morestatus" message from formatter data (BC) They are just printable messages, not data that should be fed to JSON or templater.

tests: show that the structure of the more status output looks weird Each dict should represent data of the same kind.

phabricator: add testedwith boilerplate

narrow: extract wdir cleanup function to make it extensible We have an overlay filesystem which shows the entire repository, and unlinking a file that's in the underlying data store will create "tombstone" entries, which are going to cause our automatic tracking to re-add these directories. We need to use a different (non-posix) interface to clean up items in the working directory that are no longer relevant. Extracting this to a function lets us use extensions.wrappedfunction and perform this cleanup work, even if the paths aren't in the dirstate (they may have been removed in the past and thus entirely "tombstone" entries already, part of hgignore, exclusively directories (possibly empty), or other edge cases).

changegroup: reintroduce some comments that have gotten lost over the years I got concerned about the correctness of the pruning logic, but I was misreading it. I didn't figure that out until I walked all the way back to 0252abaafb8a from 20111, where I was finally able to see (in the deleted side of the change!) a complete explanation from b6d9ea0bc107 in 2005.

changegroup: tease out a temporary prune method for manifests It's extracted so extensions can filter manifest nodes if needed. This is an unfortunate hack, but I think I only need it for manifests. The long-term solution will be to rework the relationship between changegroups and storage so that this isn't required. Differential Revision: https://phab.mercurial-scm.org/D4685

bundle2: make server.bundle2.stream default to True Support for bundle2 streaming clones has been shipped in Mercurial 4.5 (7eedbd5d4880), but was never activated by default. It's time to have more people use it. The new format allows streaming clones to transport cache (hooray for speed) and phaseroots (fixes phase-related issues). Changes in tests: bundle2 capabilities now have "stream=v2" (plus a '\n' as a separator) and therefore take 14 bytes more: "%0Astream%3Dv2". Tip for tests that have data encoded with CBOR: 0xd3 - 0xc5 = 14. $USUAL_BUNDLE2_CAPS$ replaces $USUAL_BUNDLE2_CAPS_SERVER$, which is the same thing, but without "stream=v2". Since streaming clones now also transfer caches, the reported byte and file counts are higher (e.g. 816 bytes in 9 files instead of 613 bytes in 4 files, a bit of --debug and manual math confirms that the caches take these extra 203 bytes in 5 files).

tests: split capabilities into separate lines while searching for "narrow" This test is interested only in capabilities that are related to narrow, so let's omit everything else. Makes it easier to update other capabilities (and "rev-branch-cache" is one of the usual patterns that are already present in tests/common-patterns.py anyway).

py3: resolve Unicode issues around `hg serve` on Windows Presumably we're going to want to use CreateProcessW(), and possibly get rid of pycompat.getcwd() here (which maps to the DeprecationWarning causing os.getcwdb()) to use os.getcwd() directly. But this was a minimal change to get rid of some stacktraces in test-run-tests.t.

run-tests: avoid os.getcwdb() on Windows Any call to this issues a DeprecationWarning about the Windows bytes API being deprecated. There are a handful of these calls in core, but test-run-tests.t was littered with these, as it's printed everytime run-tests.py is launched. I'm not sure what the long term strategy for Unicode on Windows in the test runner is, but this seems no worse than the current conversion strategy.

run-tests: quote PYTHON when spawning a subprocess Same reason as 5abc47d4ca6b. This covers running *.py tests, as well as inline python blocks. I didn't hit the path around line 3079, but it seems correct to quote.

narrow: add test showing that local-to-local narrow clones don't work It turns out they've never actually worked: prior to some recent refactoring they just unintentionally followed the full-clone path, which we unintentionally relied on in a test at Google.

fastannotate: process files as they arrive peer.commandexecutor()'s context manager waits for all responses to arrive in its __exit__() method. We want to process the results as they arrive, so we should do that inside the context manager scope. Note that the futures' result() methods have been replaced to make sure that the command executor's sendcommands() method is called when the first future's result is requested, so we don't need to do that. A minor side-effect is that we can no longer easily tell when the server has started sending us responses, so that long statement was lost.

py3: make osenvironb a proxy for, instead of a copy of os.environ where needed Without this, TESTDIR and a few other variables weren't defined in the *.t test. I didn't bother implementing all of the view functions for simplicity. All that is actually used is __{get,set}item__(), get() and pop(), but the rest seems easy enough to add for futureproofing.

memctx: simplify _manifest with new revlog nodeids This was originally written before we had modifiednodeid and addednodeid, so we had to get the parents of the context, the data from the function, and then hash that. This is much more simple now and helps refactor more code later.
