Yep. We should definitely fix that. realpath on argv[0] seems like the right thing.

We should definitely fix that. realpath on argv[0] seems like the > right thing. Wouldn't it be better to have a method of finding the absolute file name of the executable from which the process was started, regardless of what argv[0] says? The way to do that is system-dependent (on GNU/Linux, I believe you need to readlink ("/proc/self/exe") or somesuch, for example), but AFAIK this can be done on all platforms we support.

It does, although it drags in a bunch of other Gnulib modules, as this=20 stuff is wildly system-dependent. For ordinary Emacs installation, I've long thought that a better=20 approach is to store the default .pdmp file as a readonly char array=20 within the Emacs executable itself. This would be easier for installers,=20 sysadmins and users, as it would entail no funny rules about installing=20 two files, keeping them in sync, symlinks, PATH, argv[0], relative=20 names, security, etc. Perhaps native compilation effectively does this for us already? If so,=20 then the fix for this bug report would be "use native compilation".

The pdmp file includes offsets of data structures within the Emacs executable. Rebuilding the executable with a big char array will change these offsets and invalidate the pdmp blob you're trying to embed. Now, you could try to guess the size of the blob ahead of time, include a dummy embedded array of that size in Emacs, dump, and then overwrite the embedded array post-build, but there's no guarantee that doing that would actually work on all systems. I'd rather get out of the business of mucking with executable files even if it means we have a bit of extra complexity arising from having to deal with out-of-band pdmp files.

Maybe we could avoid this problem by moving most of the Emacs executable to a shared library, so the Emacs executable would be just a `dump` variable and ` main` function which passes it to an entry point provided by libemacs.so`. I'm not sure I like the idea of building a shared lib and the extra complexity of making sure the Emacs executable finds it.

Is it really self-contained though? It would still need *.elc files, right?

But I agree with Daniel that the former is more important than the latter. If we do find a way of achieving the latter without risking the former, then sure.

It could just as well be the source of a memory copy to its runtime location; everything would then work just like today except that the dump file is embedded into the executable. Copying the dump on startup will hurt performance --- the dump is meant to be used directly from a disk-backed file. I'm also not entirely clear on how you're planning on avoiding the usual problems with executable modification --- relinking the executable can change all the locations of the symbols in the binary, and if symbol locations change, any previously-generated dump becomes invalid. Even if on *some* platforms *today* we can replace an embedded dump image in an already-built executable without re-linking the thing, there's no guarantee that we can continue doing that. (For example --- imagine a future platform that signs all binaries during the build process.) Modifying binaries is always a platform-specific thing and doing it for Emacs risks forward compatibility. Usin a separate dump file relies only on public APIs guaranteed to work forever.

Is the cost of the all-sequential) paging-in noticeable? Surely a fair = part of it will be required more or less immediately anyway. The worst-case cost of an empty `-batch -Q` run actually decreased = somewhat when forcing the dump to be read up front, although admittedly = that was from a hot cache. > relinking the executable can change all the locations of the symbols = in the binary, and if symbol locations change, any previously-generated = dump becomes invalid.

No, I don't think that's a viable way. As you say, in-place modification = wrecks havoc with any sort of binary checksumming.
