repoview: only pin obsolete wdir parents while there are unresolved conflicts I noticed after doing an update from an obsolete revision with a dirty wdir that the obsolete commit stayed visible for no obvious reason. It was decided in 85b03b1e4715 not to clear mergestate once all of the conflicts were resolved, in order to allow re-resolving. Since the point of pinning the obsolete parents was to allow resolving in the first place (aaeccdb6e654), it makes sense to also gate it on whether or not there are any remaining files to resolve. This might result in pinning again if files are marked unresolved again, but that seems reasonable, given that it still solves the original issue. Note that this isn't purely cosmetic- pushing with a pinned obsolete revision is likely to cause complaints about pushing multiple heads or other unexpected errors. So the faster it comes out of that state, the better. Differential Revision: https://phab.mercurial-scm.org/D9248

url: do not continue HTTP authentication with user=None (issue6425) I initially thought this is a py3-compat bug of passwordmgr._writedebug(), but actually returning (None, str) pair is wrong at all. HTTP authentication would continue with user="None" in that case. Since registering a password of user=None should also be wrong, this patch simply adds early return.

ui: fix echo back of ui.prompt() to not concatenate None as bytes Spotted while writing tests for the issue6425. The default value may be None.

commit: don't change phases for preexisting commits I noticed when pulling with hg-git in a repository that already had the changes, but pulled from another Mercurial repository. This meant that hg-git would re-create exact matches of the changesets, and if they were public, they'd get reverted to drafts. Differential Revision: https://phab.mercurial-scm.org/D9253

demandimport: don't raise AttributeError if `exec_module` is missing I assume this was meant to do the check gracefully. After shoveling a bunch of modules into the ignore list in order to get keyring to work out of the box on CentOS 8, I hit the following error accessing the password, which the change fixes. Now the SecretStorage backend works out of the box, without any edits to the ignore list. ** Unknown exception encountered with possibly-broken third-party extension mercurial_keyring ** which supports versions unknown of Mercurial. ** Please disable mercurial_keyring and try your action again. ** If that fixes the bug please report it to https://foss.heptapod.net/mercurial/mercurial_keyring/issues ** Python 3.6.8 (default, Apr 16 2020, 01:36:27) [GCC 8.3.1 20191121 (Red Hat 8.3.1-5)] ** Mercurial Distributed SCM (version 5.5.2) ** Extensions loaded: evolve, topic, rebase, absorb, mercurial_keyring Traceback (most recent call last): File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/mercurial_keyring.py", line 230, in _read_password_from_keyring password = keyring.get_password(KEYRING_SERVICE, pwdkey) File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/keyring/core.py", line 53, in get_password return _keyring_backend.get_password(service_name, username) File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/keyring/backends/chainer.py", line 51, in get_password password = keyring.get_password(service, username) File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/keyring/backends/SecretService.py", line 79, in get_password return item.get_secret().decode('utf-8') File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/secretstorage/item.py", line 105, in get_secret decryptor = Cipher(aes, modes.CBC(aes_iv), default_backend()).decryptor() File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/cryptography/hazmat/backends/__init__.py", line 15, in default_backend from cryptography.hazmat.backends.openssl.backend import backend File "<frozen importlib._bootstrap>", line 971, in _find_and_load File "<frozen importlib._bootstrap>", line 955, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 665, in _load_unlocked File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/hgdemandimport/demandimportpy3.py", line 53, in exec_module self.loader.exec_module(module) File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/cryptography/hazmat/backends/openssl/__init__.py", line 7, in <module> from cryptography.hazmat.backends.openssl.backend import backend File "<frozen importlib._bootstrap>", line 971, in _find_and_load File "<frozen importlib._bootstrap>", line 955, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 665, in _load_unlocked File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/hgdemandimport/demandimportpy3.py", line 53, in exec_module self.loader.exec_module(module) File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/cryptography/hazmat/backends/openssl/backend.py", line 14, in <module> from six.moves import range File "<frozen importlib._bootstrap>", line 971, in _find_and_load File "<frozen importlib._bootstrap>", line 951, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 894, in _find_spec File "/home/mharbison/hg_py3.6.8_venv/lib64/python3.6/site-packages/hgdemandimport/demandimportpy3.py", line 117, in find_spec and getattr(spec.loader, "exec_module") AttributeError: '_SixMetaPathImporter' object has no attribute 'exec_module' Differential Revision: https://phab.mercurial-scm.org/D9243

automation: upload Python 3.9 Windows wheels We are producing these. We should be publishing them.

contrib: split Windows requirements into multiple files Package support for Python 2 has diverged significantly. It is no longer trivial to maintain a single requirements file that supports both Python 2 and 3 because the set of packages and versions varies wildly. This commit split up the Windows requirements files so we have variants for Python 2 and 3. As part of this, I also renamed the files to have what I believe to be more reasonable naming ("win32" felt like a weird identifier to me). We can see that some package versions decreated on 2.7. This is because the old pinned versions weren't compatible with Python 2.

relnotes: add diffcontains() to new features list
