propertize reverses the order of elements

[ngortheone]

Something that I discovered during investigation on #1513

This is fixed in emacs 27.0.50

ELISP> (propertize " " "1" "2" "3" "4" "5" "6")
#(" " 0 1
  ("1" "2" "3" "4" "5" "6"))

But both in Emacs 26.2 and in Remacs still have it

ELISP > (propertize " " "1" "2" "3" "4" "5" "6")
#(" " 0 1
  ("5" "6" "3" "4" "1" "2"))

Since propertize was ported we can't rely on C patch to fix

But will us fixing it now break the Lisp code we have from 26? That is the key question.

I am working on bring all of the removed C back into the project so we can track these kinds of changes more easily.

The confusion is that remacs reports version 27.0.50, while mostly behaves like 26.2.
As I was investigating #1513
I have loaded melpa packages from 26 branch and I have different behavior. Icons are resizing but the images are all blank now...(only icon frame is visible) :(

This is a source of problems with spacemacs. It uses version number to determine where from packages should be downloaded

Yes the 27.0.50 is a mistake we need to fix. Please open a ticket so we can revert the files to the proper versions.

Yes the 27.0.50 is a mistake we need to fix.

@shaleh I don't really think so. Remacs is based on emacs' master branch (current merge base is 64c85e68) and it has version 27.0.50

@shanavas786 it was started from master. Like 3 years ago. It is not 27.x compatible. All of the 27.x in remacs is in error.
