Subject: 28.0.50; org-babel-tangle-file tangles code blocks starting with
 #+begin_src :tangle no
Date: Fri, 27 Aug 2021 00:53:00 +0200

Hello,

Here are the steps that led to code blocks being tangled I did not 
expect to:

emacs -Q
C-x C-h: ~/org-roam/example.org
content of example.org (excluding "):
"
#+begin_src emacs-lisp
(setq some-emacs-lisp-variable t)
#+end_src

#+begin_src :tangle no
;;This line should not be in the elisp code
#+end_src
"

open scratch buffer through menu.
type into scratch buffer:
(org-bable-tangle-file "/home/tassilo/org-roam/example.org"
"/home/tassilo/org-roam/example.el")
M-x:emacs-lisp-mode
Select (with mouse) the above line and evaluate region through menu.
I see in the minibuffer: "Tangled 2 code blocks from example.org"
After typing C-h C-f: ~/org-roam/example.el
I see the file content of "example.el" (excluding "):
"
(setq some-emacs-lisp-variable t)

;;This line should not be in the elisp code

"

This is not what I expected. I would have expected that the code block
with ":tangle no" added would not be tangled. That is how I understood
this section of the org-manual:
(https://orgmode.org/manual/Extracting-Source-Code.html)
"The ‘tangle’ header argument specifies if the code block is exported to
source file(s). [...] 'no' The default. Do not extract the code in a
source code file. Example: ‘:tangle no’."

(Sorry for the delayed reply.  This message, unlike the initial post,
will be redirected to the Org list, where you're more likely to get a
response.)

Org sees the last block above as a source block of language ":tangle".
Here's what org-element-at-point reports:

  (src-block (:language ":tangle" :switches nil :parameters "yes"...)

org-lint will complain about this block:

     2 nil   Missing colon in header argument "yes"

And, were you to use a bare source block (i.e. drop ":tangle no"), it
would complain about a missing language:

     2 nil   Missing language in source block

So, I think the source block is mis-specified, and I'm not sure there's
much that Org should do here, but perhaps others will chime in with
their thoughts.

Well. I can see why you did not expect this, but the real cause is a
typo in your code block.

#+begin_src :tangle no
;;This line should not be in the elisp code
#+end_src

is viewed by Org mode as src block written in ":tangle" programming
language :) That's because you forgot to put language in the block and
Org takes the first word after #+begin_src and the language name.

This block does not have :tangle attribute and thus "example.el"
supplied in your function call is being used :)

On Org side, we may catch such scenarios in org-lint.
M-x org-lint currently reports no problem with the above block.

Not urgent fix. Patches are welcome :)

org-lint does catch such problem.
Not a bug.
Closing.
