* bug#58653: 29.0.50; Long lines in *compilation* buffer

In GNU Emacs 29.0.50 (build 1, aarch64-apple-darwin21.6.0, NS
 appkit-2113.60 Version 12.6 (Build 21G115)) of 2022-09-21 built on
 Mini.fritz.box
Repository revision: 1231a601ebe1fd9fe454c504dbeb9267440242e7
Repository branch: master
Windowing system distributor 'Apple', version 10.3.2113
System Description:  macOS 12.6

Configured using:
 'configure --cache-file /Users/gerd/tmp/config.cache.master
 --with-native-compilation'

I did not find an easer way to reproduce this, sorry for that.

Configure Emacs with:

  ./configure --disable-silent-rules

so that compilation commands are shown in full.

Introduce something producing a warning or error in the C code, for
example in lisp.h.

Then do a full parallel build of Emacs (-j8 here).  This produces, on my
system, lines invoking gcc which are ca. 2000 chars wide.  These lines
are by default displayed with a [...].

Bug:

The errors or warnings appear sometimes truncated. For example, the file
name of the error message is not displayed.  Clicking on the [...]  does
not change that.  (And with the truncated messages, next-error cannot
work, ...)

I have no idea what that might be, so I'm just mentioning anything that
might be relevant, such as the parallel build.

I'm meanwhile pretty sure that this does not happen when I invoke make
with -j1.

Another observation: I have truncate-lines nil in *compilation*.  The
continuation lines for the long gcc commands are displayed correctly
with these "curly" arrows.  The lines showing errors or warnings that
are chopped somehow display a triangle on the left margin, as if the
line were scolled.  I can't make sense of that at all.

Toggling truncate-lines, BTW, doesn't restore the missing text
(filenames for example).  

If someone has an idea where I could look for this in the code, please
let me know.

That "triangle" is likely the "overlay-arrow" as it is displayed on
GUI frames.

Yes, indeed (slapping my head).

BTW, I've now checked that the missing text is really not in the buffer,
so it's not a display problem of some sort.

How strange.

I'm not surprised ;-)

> How strange.

Two possible suspects:

  . "M-x compile", which does something to truncate the long lines
  . the compiler itself: perhaps Emacs tells it the dimensions of the
    window, and the compiler adapts its output accordingly

Have fun.

Ok, thanks.

Hehe :-).

I had some fun, and it gets even a bit weirder: The missing text doesn't
seem to be lost at all, it's just somewhere else.  Example:

  :22: warning: 'sprintf' is deprecated: ...

This should actually be xdisp.c:22:...

The xdisp.c can be found above that warning as part of a long line

  ebrew/Cellar/libidn2/2.3.4/include -isystem
  /opt/homebrew/Cellarxdisp.cAWK=awk ./mapconv glibc/IBM857.gz '/^<.*[
                      ^^^^^^^                   

And the newline before "AWK=" is probably also somewhere else.

That's a start :-/.

Exactly the same happens when building in M-x shell.  And it doesn't
happen in a Terminal window.

Are you building with -jN, i.e. in parallel?  Then what you see could
be the consequence of several processes writing simultaneously to the
same device.  If you use GNU Make, try adding the --output-sync=line
switch to the Make's command line.

Yes, I am building with GNU make 3.81, -j8 by default, which doesn't
seem to recognize --output-sync.

I'll try to get a newer gmake, and report back.

Yay, it works with GNU make 4.4!  And I was already digging in
process.c...

Thank you very much!
