Re: new flymake bug: error in process sentinel: Invalid function: flymake-log

[Yuta Yamada]

I can't reproduce it. flymake-log is a(n autoloaded) lisp macro, not a
function, and it's only invoked in the elisp-flymake-byte-compile
backend's sentinel in elisp-mode.el that sentinel detects an obsolete
check (BTW your report is still helpful because it shows a case where
that detection was a false positive)

How did you compile your emacs-26?

I'm sorry, I was checking on master, not emacs-26 branch and

testing branch on emacs-26 without your fixing commit couldn't reproduce

the bug by myself. So please ignore my bug conformation. (you fixed another bug was great though)

Also I must admit that I didn't use the `make bootstrap" to compile emacs

I was using below script:

---

git reset --hard HEAD
git clean -xdf
git pull git://git.savannah.gnu.org/emacs.git

./autogen.sh all
./configure \
  CFLAGS='-O2' \
  --with-dbus -without-toolkit-scroll-bars \
  --with-xim --without-makeinfo --with-modules \
  --with-x-toolkit=lucid

make

---

I've just pushed a fix the false detection problem in the emacs-26
branch. The fix will (perhaps unfortunately) shoosh your error as well,
so take note of the git HEAD you were in, and try to "make bootstrap".

Sorry, I just did git pull things without thinking, but I built emacs around Oct 16 as

fa as remember (before I submit new flymake's feature request on devel) in case if you care.

How did you compile your emacs-26? The error you get could be caused by
the fact that the autoload didn't kick in when it should, but it's also
a bit confusing to me how it should work at all since it's a macro (that
expands to flymake--log-1) and elisp-mode.el is preloaded. Comment from
more knowledgeable folk is welcome at this point.
