I'm developing a patch for https://trac.torproject.org/5926, to stop
patching tor-browser.git C++ code, but then I noticed two files in
torbutton, jshooks.js and jshooks4.js:
These files seem to be relevant to the patch, and I have some
questions about them:
1. In jshooks.js, the series of lines that re-define the window.Date
prototype, as controlled by line 72, `if(window.__tb_hook_date ==
true)`, is never called, as far as I can tell, because __tb_hook_date
is never defined. Indeed, if that code were called, then the bug I'm
working on would already be mostly fixed. Is there a reason this
section of jshooks.js is being retained? Should it be re-activated or
is it better for me to continue with a C++ patch?
2. jshooks4.js doesn't seem to be in use at all. Is that correct?
Would it make sense to remove this file from the master branch?
3. In general, what's the approach for deciding whether to patch
Mozilla C++ code vs torbutton JS code for anti-fingerprinting and
similar bugs? I understand there is a desire to move more toward C++,
but I'm not sure what the overall plan is.
Thanks for any insight!
