meson: add

[neheb]

Significantly faster than autotools thanks to Ninja and shorter code.

https://github.com/rakshasa/libtorrent/pull/390 was rejected because of speed. This is much faster.

Unfortunately, there seems to be an issue where the tests fail:

I've wasted hours trying to replicate autotools at this point to no avail.

The issue here might also be what's wrong with the BSDs. It's just now happening everywhere.

meson's pkgconfig file adds links to libcrypto and pthread, as it should.

subprojects available for zlib and libkqueue. None for cppunit unfortunately. Would allow testing on OmniOS.

If this gets merged, it means I need to keep two build systems up-to-date in order to merge PRs.

And one of them I have no experience with.

This is still a completely unacceptable solution.

[stickz]

I would recommend adding cmake instead as a build solution. It's entirely optional, widely used and easily understandable.

I disagree with this. I'm not wasting more hours reimplementing the build.

Sure. I've marked it as draft.

Still suffers the issue of adding indeterminate future overhead for very little real-world benefit.

This started as a big endian platform test build PR and morphed into a replacement (or rather, duplication) of the whole build system.

Experience would make you say early on that this is a bad idea, and if really needed should be maintained separately outside of the main repository.

If replacing the build system made sense, it would make so on the merits of how it is better in the general case. Not merely to add support for a single platform

[neheb]

to be fair I've had this locally for a long time. Adding libkqueue support allowed testing with that code path. I cleaned it up to match autotools as much as possible, in addition to some PRs cleaning up old autotools stuff.

The big endian thing is not related.

The main configure.ac clocks in at 118 lines. The main meson.build file is 136, which takes functionality from the various scripts. I think there's something to be said for simplicity.

The failures are now:

test_tracker_list.cc:370:Assertion
Test name: test_tracker_list::test_scrape_success
assertion failed
- Expression: tracker_0.is_busy()

tracker_test.cc:168:Assertion
Test name: test_tracker_list::test_scrape_failure
assertion failed
- Expression: is_busy() && is_open()

test_tracker_list.cc:487:Assertion
Test name: test_tracker_list::test_has_active
assertion failed
- Expression: "01110"[2] == '0' || tracker_2.is_busy()

???

[neheb]

ummm this is interesting.

by adding 3 extra files that i missed, tests succeed now. Wow what a waste of time that was.

[neheb]

sped up test compilation. It matters on slow platforms.

got execinfo working on BSDs: https://github.com/neheb/libtorrent/actions/runs/15262288336

All platforms are now green: https://github.com/neheb/libtorrent/actions/runs/15289713193

[neheb]

libatomic linking fixed.
