* lisp/erc/erc-track.el (erc-track--shortened-names): New variable to
stash both the latest inputs and most recent result of
`erc-track-shorten-function'.
(erc-track--shortened-names-current-hash,
erc-track--shortened-names-set, erc-track--shortened-names-get): New
pair of generalized-variable functions and helper variable for
accessing and mutating `erc-track--shorten-prefixes'.
(erc-modified-channels-display): Avoid redundant calls to
`erc-track-shorten-function'. Mainly for use during batch processing.
* test/lisp/erc/erc-track-tests.el (erc-track--shortened-names): New
test. (Bug#67767)
* etc/ERC-NEWS: Add entry for new behavior involving the option
`erc-track-faces-normal-list'.
* lisp/erc/erc-button.el (erc-button-nick-default-face): New face to
serve as default for `erc-button-nickname-face'.
(erc-button-nickname-face): Change default value to
`erc-button-nick-default-face'.
* lisp/erc/erc-track.el (erc-track--massage-nick-button-faces): New
function to serve as Custom :set function for priority and "normal"
face-list options.
(erc-track-faces-normal-list): Fix Custom :type by loading
`erc-button' during validation so Customize chooses the correct UI
instead of a generic form field with "(mismatch)" printed alongside
the "STATE" button.
(erc-track-faces-priority-list, erc-track-faces-normal-list): Remove
values for "buttonized" `match' module faces that, if retained, would
need updating to feature `erc-button-nick-default-face' instead of
`erc-nick-default-face'. However, as noted in the NEWS entry, this
ordering of button face atop match face is not possible. Use :set
function to massage saved user values.
(erc-track-ignore-normal-contenders-p): New compatibility switch to
access pre-5.6 behavior, in which faces in
`erc-track-faces-normal-list' were only considered for promotion to
the mode line if the current face occupying that pole position wasn't
present.
(erc-track-mode, erc-track-enable, erc-track-disable): Add comments
regarding perceived futility of hooking on `erc-server-001-functions'
and likely unneeded hook removal. Run common buffer-local setup and
teardown.
(erc-track--normal-faces): New local variable, a snapshot of
`erc-track-faces-normal-list'.
(erc-track--setup): New function to stash
`erc-track-faces-normal-list' on init.
(erc-track-select-mode-line-face): Offer alternate explanation of
certain particulars in doc string.
(erc-track--alt-normals-function): New function-valued variable to
allow other modules to intervene in deciding whether to pursue and
promote a "normal" contending face.
(erc-track--select-mode-line-face): New function similar to its public
namesake except that it considers other viable candidates among the
"normal" alternatives.
(erc-track-modified-channels): Only run face selection portion when
faces are actually found. Use `erc-track--select-mode-line-face'
instead of `erc-track-select-mode-line-face'.
* test/lisp/erc/erc-track-tests.el
(erc-track-select-mode-line-face): New test.
(erc-track-tests--select-mode-line-face): New fixture function.
(erc-track--select-mode-line-face): New test. (Bug#67767)
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
