Fri, 14 Jul 2017 14:22:40 -0700 codemod: register core configitems using a script
Jun Wu <quark@fb.com> [Fri, 14 Jul 2017 14:22:40 -0700] rev 33499
codemod: register core configitems using a script This is done by a script [2] using RedBaron [1], a tool designed for doing code refactoring. All "default" values are decided by the script and are strongly consistent with the existing code. There are 2 changes done manually to fix tests: [warn] mercurial/exchange.py: experimental.bundle2-output-capture: default needs manual removal [warn] mercurial/localrepo.py: experimental.hook-track-tags: default needs manual removal Since RedBaron is not confident about how to indent things [2].

Tue, 11 Jul 2017 08:52:55 -0700 phabricator: allow specifying reviewers on phabsend
Jun Wu <quark@fb.com> [Tue, 11 Jul 2017 08:52:55 -0700] rev 33498
phabricator: allow specifying reviewers on phabsend Sometimes people want to specify reviewer explicitly for a stack. The webpage only allows changing reviewer for one revision at a time. This patch adds a `--reviewer` flag to make it easier to specify reviewers. Test Plan: On a test Phabricator instance, enable `differential.allow-self-accept`, assign myself as a reviewer and make sure it works. Also try an invalid username and make sure it raises.

match: remove unused negatematcher This was only used by the sparse extension's dirstate._ignore override, which no longer exists. Differential Revision: https://phab.mercurial-scm.org/D60
Tue, 11 Jul 2017 10:46:35 -0700 sparse: override dirstate.walk() instead of dirstate._ignore
Martin von Zweigbergk <martinvonz@google.com> [Tue, 11 Jul 2017 10:46:35 -0700] rev 33496
sparse: override dirstate.walk() instead of dirstate._ignore Instead of treating files that are outside the sparse config as ignored, this makes it so we list only those that are within the sparse config by passing the sparse matcher to dirstate.walk(). Once we add support for narrow (sparseness applied to history, not just working copy), we will need to do a similar restriction of the walk over manifests, so this will be more consistent then. It also simplifies the code a bit. Note that a side-effect of this change is that files outside the sparse config used to be listed as ignored, but they will now not be listed at all. This can be seen in the test case where "hg purge" no longer has any effect because it doesn't see that the files outside the space config exist. To fix that, I think we should add an option to dirstate.walk() to walk outside the sparse config. We might expose that to the user as --no-sparse flag to e.g. "hg status" and "hg purge", but that's work for another day. Differential Revision: https://phab.mercurial-scm.org/D59

Jun Wu <quark@fb.com> [Wed, 12 Jul 2017 15:24:47 -0700] rev 33495
patch: use devel.all-warnings to replace devel.all It appears to be a misspell in patch.py.
Wed, 12 Jul 2017 18:37:13 -0400 sslutil: inform the user about how to fix an incomplete certificate chain
Matt Harbison <matt_harbison@yahoo.com> [Wed, 12 Jul 2017 18:37:13 -0400] rev 33494
sslutil: inform the user about how to fix an incomplete certificate chain This is a Windows only thing. Unfortunately, the socket is closed at this point (so the certificate is unavailable to check the chain). That means it's printed out when verification fails as a guess, on the assumption that 1) most of the time verification won't fail, and 2) sites using expired or certs that are too new will be rare. Maybe this is an argument for adding more functionality to debugssl, to test for problems and print certificate info. Or maybe it's an argument for bundling certificates with the Windows builds. That idea was set aside when the enhanced SSL code went in last summer, and it looks like there were issues with using certifi on Windows anyway[1]. This was tested by deleting the certificate out of certmgr.msc > "Third-Party Root Certification Authorities" > "Certificates", seeing `hg pull` fail (with the new message), trying this command, and then successfully performing the pull command.
