Not _any_ other flag, but flags parsed in command-line-1.

If we restored Emacs from a dump file, we should filter --dump-file
(and the following argument, if --dump-file doesn't end in a '=') in
init_cmdargs, so that startup.el doesn't see it.

BTW, I can’t use —dump-file flag with ~, otherwise it complains

    emacs: could not load dump file "~/.emacs.d/cache/emacs.pdmp": could not open file

Using a root path (/Users/yuan/.emacs.d/…) works fine. Is this expected?

Yes, I think so.  Emacs loads the dump file very early during startup,
and the various known directories are not yet set up at that point.

I’m still seeing this in the latest master build. Could you give me some
pointers on how to fix this? If it’s not too complicated maybe I can fix
it.

I thought I did just that in

Do you have follow-up questions?

Ah, yes. How can I check if Emacs is restored from a portable dump file? I see strcmp (temacs, "pdump”) in main but I don’t think that’s in scope in init_cmdargs. Thanks.

One way is to use the function pdumper-stats.

Thinking more about it, maybe I shouldn’t check if Emacs is restored from a portable dump file, since having “—dump-file” in argv should mean that Emacs is restored from a portable dump file anyway.

[-- Attachment #1: Type: text/plain, Size: 308 bytes --]

Here is my first attempt. The implementation of argmatch gives me an impression that when the flag only have one dash, you are not supposed to add “=“ after it. IOW, -dump-file=xxx is a misuse. BTW, I don’t see a test for emacs startup in /test/src. Are there test cases that I should test against?

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I tried reproducing this on the current Emacs trunk:

larsi@giant:~/src/emacs/trunk$ ./src/emacs --batch -q --eval '(dump-emacs-portable  "/tmp/emacs.pdmp")'
Dumping fingerprint: 242a38e947fb351c885b84edcc58743b99c0803abfc37d2f3a62eb0ed696c781
Dump complete
Byte counts: header=100 hot=7603292 discardable=135072 cold=3591048
Reloc counts: hot=428962 discardable=5173
larsi@giant:~/src/emacs/trunk$ ./src/emacs -Q --dump-file /tmp/emacs.pdmp 

But it seems to work fine there.  Are you still seeing this issue in
recent Emacs versions?

No. I tried and it works fine now. Closed this report. Many thanks for your work Lars!
