Load change in master?

Load change in master?

[Ergus]

Hi I just build the master branch and the load time increased a
lot. Looking at the *Message* buffer I see that even with the -Q option
it loads a lot of files (and prints messages) it was not doing that
before:

----------------------------------

Do we really need to load so many languages for example?

My load time increased 4 times even with -Q and no file it takes more
than 2 seconds and before it was actually faster than vim.

What changed?

Best,
Ergus

This is Bug#35503; probably emacs is failing to find the dump file due
to symlinks.

Hi I don't have a link for that, I have emacs in a different path and I
add it to the system PATH in the bashrc. This is not supposed to fail
right?

How can I debug how emacs looks for the dump file?

Step with a debugger into load_pdump, which is called from 'main'.

Yes, it's supposed to fail (until we fix bug#35503 that is), unless
Emacs has been "make install"d properly.
In the mean time I use a script (in my PATH) which runs Emacs by
specifying its full file-name.
