Summary

Upstream changes:
https://raw.githubusercontent.com/emacs-mirror/emacs/master/etc/NEWS.26

This is the first release candidate for Emacs version 26.1. This is not intended to be committed to the ports tree until the final release, but is to allow for some testing before the final release.

Hi Joseph,

Thanks for initiating this.

I get build error on 11-amd64:

===========================================================================
====> Running Q/A tests (stage-qa)
====> Checking for pkg-plist issues (check-plist)
===> Parsing plist
===> Checking for items in STAGEDIR missing from pkg-plist
===> Checking for items in pkg-plist which are not in STAGEDIR
Error: Missing: libexec/emacs/%%EMACS_VER%%/%%GNU_HOST%%/movemail
===> Error: Plist issues found.
*** Error code 1

Thanks!

Fix more issues before 26.1 is released

• fix plist issue with MAILUTILS knob
• fix issue with GFILE option and exclude that option for the nox flavor
• conform to PH chapter, 'Order of Variables in Port Makefiles'

TODO: update canna patch

More changes to prepare for upcoming 26.1 release

• Incorporate latest canna patches.
• Remove workarounds for Bug 227799.
  • Configure now seems fine whether devel/liblockfile is install or not.
• Customize COMMENT for canna and nox flavors.
• Remove legacy lldb for gud patch.
  • The patch added very little over running lldb on the command line. Moreover, gud is deprecated. Hopefully the lldb-mi implementation will be completed soon.

Hey

Just realized that since this update involves a new Emacs release, are you also planning to update Mk/Uses/emacs.mk and PORTREVISION bump all emacs-dependent ports ?

Thanks!
