Requests for current-next (15.0-->15.1)

Could we have this :

Code:

--with-native-compilation

From emacs wiki :

Quote:

GccEmacs refers to the --with-native-compilation configuration option when building Emacs, which adds support for compiling EmacsLisp to native code using libgccjit. All of the Elisp packages shipped with Emacs are native-compiled, providing a noticeable performance improvement out-of-the-box. Third-party packages are also compiled to achieve further performance improvements.

From Doom Emacs that rang a bell :

Quote:

Users will see a substantial performance gain by building Emacs with native compilation support, availible in emacs 28+.

In the Slackbuild

Code:

# Without this, the emacs-no-x11 binary won't work with the installed files:
PDUMPER=${PDUMPER:-"--with-pdumper=no --with-dumping=unexec"}

and

Code:

'--with-native-compilation' is not compatible with unexec

Missed that, thank you.

Maybe we could have it in emacs-with-X11 ?

I could live with

Code:

emacs-with-X11 -nw

FWIW, packages for emacs-nativecomp-29.1 and its dependency libgccjit for Slackware 15.0 and compatible distributions are available in http://slackware.uk/slint/x86_64/sli...0/slint/extra/, its dependency tree-sitter in http://slackware.uk/slint/x86_64/slint-15.0/slint and their sources in http://slackware.uk/slint/x86_64/slint-15.0/source/.

I do not use emacs, but users who requested and tried it did not find any issue or drawback switching to emacs-nativecomp (package version 57.0 was provided on Tuesday 11 April 2023, updated since)

I guess I would have first to request for gcc to have this change from

Code:

--enable-languages=ada,c,c++,d,fortran,go,lto,m2,objc,obj-c++ \

to

Code:

--enable-languages=ada,c,c++,d,fortran,go,lto,m2,objc,obj-c++,jit \

That would make things easier to get the modded emacs to run

Can we bump pango to 1.51.0? Its a trivial update and built fine here when I tested it.

You'd also need --enable-host-shared which comes at a performance cost. The recommended solution for distributors is to build gcc twice: first just for jit with --enable-host-shared, and then again for everything else without --enable-host-shared.

BTW, the native compilation will make emacs use a lot more space in each users home directory for all the compiled objects — unless you use --with-native-compilation=aot (which will result in then all going into /usr at emacs build time.

As for the emacs package itself, IMO it'd be best to split the "with X11" and "without X11" builds into separate packages and perhaps put one of them (I'd suggest the without X11) in extra/ as an alternative (or just drop it if no one cares about it).

That's far out of my league.

Thanks for raising this.

I guess that will happen if Pat thinks it worths it. Seems to much of a hassle for me at this very moment.

Plocate

Plocate Is A Much Faster locate (Drop-In Replacement For mlocate)

Quote:

plocate is a newer, much faster locate. It's based on posting lists, giving much faster searches on a much smaller index.

The command-line tool is a drop-in replacement for mlocate (Merging Locate; a restricted-access database, only showing filenames accessible to the user) in nearly all aspects, including reusing the mlocate database (plocate creates its own index using plocate-build which reads the database made by updatedb), and is fast on SSDs and HDDs alike.

Quote:

plocate works by creating an inverted index over trigrams (combinations of three bytes) in the search strings, which allows it to rapidly narrow down the set of candidates to a very small list, instead of linearly scanning through every entry. It does nearly all I/O asynchronously using io_uring if available (Linux 5.1+), which reduces the impact of seek latency on systems without SSDs.

It's not quite a drop-in replacement:

https://devctrl.blog/posts/plocate-n...e-using-btfrs/

Thanks to your post I tried it out, and... first try failed to find the file I was looking for (after "removepkg mlocate", "plocate-build /var/lib/mlocate/mlocate.db /var/lib/plocate/plocate.db", "/etc/cron.daily/plocate"). I was perplexed until finding the above article.

So changing PRUNE_BIND_MOUNTS to "no" in /etc/updatedb.conf and rerunning /etc/cron.daily/plocate, now it works.

Much faster I might add:

Code:

time mlocate <file>:
real    1m26.909s
user    1m26.469s
sys     0m0.436s

time plocate <file>:
real    0m0.014s
user    0m0.008s
sys     0m0.005s

So yeah I'm switching to plocate because I often find myself avoiding using mlocate because of how slow it is for me.

Hi , the package zxing-cpp is used to link by

gst-plugins-bad-free

Then the correct directory is under /l not under /kde cause is not especific/only librarie used by kde.

Thanks for the work!
