build: rework gyp files for zlib by richardlau · Pull Request #33044 · nodejs/node

richardlau · 2020-04-24T18:02:08Z

Restructure the gyp file based on the upstream gn file, breaking out
the files with optimizations that need additional compiler flags.

Use a copy of the GN-scraper.py script to reduce the amount of hand
editing when the zlib dependency is updated.

Another reason I initially moved the gyp file was that I was hoping to reuse tools/v8_gypfiles/GN-scraper.py but I wasn't able to work out how to reference it so for the moment it has been copied.

I'm not sure if this fixes #33019 -- I no longer see the reported errors in zlib when compiling with configure --dest-cpu=x86 but the shared Linux server I've been working on doesn't have multilib so the build fails compiling V8.

jasnell · 2020-04-24T18:11:20Z

fwiw, I'd much rather we keep the relevant gyp files in the deps folder and consistently use a pattern that is more like what we do with openssl, nghttp2, etc... where the source files for the dependency are in a subdirectory (e.g. deps/openssl/openssl and deps/nghttp2/lib)

richardlau · 2020-04-24T18:38:58Z

@jasnell Moved the gyp file back to deps/zlib.

Also fixes #32856.

Sigh. I ran benchmarks over the weekend and there are notable regressions. AFAICT the build logs (see the second link below) show we're passing in the expected compiler flags/definitions for the optimized files based on the BUILD.gn file so ¯\_(ツ)_/¯. I'm not intending to spend a lot of time on this as it's not high on my list of priorities.

Reportedly this fixes building on 32-bit x86 (#33019 (comment)) (which is an unofficial build platform) but I'm assuming the drop in benchmarks would prevent this landing. I don't have the time to investigate this further, so I've put a help wanted label in case anyone else is interested and has the time to look into the benchmarks.

richardlau · 2020-09-08T16:33:27Z

Another report that this fixes building on 32-bit Linux: nodejs/help#2943 (comment)

Trott · 2020-10-17T01:47:12Z

I rebased against master and force-pushed in the hope that it will somehow cause the performance regression to go away.

Benchmark CI: https://ci.nodejs.org/view/Node.js%20benchmark/job/benchmark-node-micro-benchmarks/670/

UPDATE: Bummer. Still shows the performance degredation.

06:15:54 06:15:54 Be aware that when doing many comparisons the risk of a false-positive
06:15:54 result increases. In this case there are 28 comparisons, you can thus
06:15:54 expect the following amount of false-positive results:
06:15:54 1.40 false positives, when considering a 5% risk acceptance (*, **, ***),
06:15:54 0.28 false positives, when considering a 1% risk acceptance (**, ***),
06:15:54 0.03 false positives, when considering a 0.1% risk acceptance (***)

Do we need to update/run license-builder.sh for this? And might this be better living in tools?

¯\_(ツ)_/¯. It's a copy of the one in tools/v8_gypfiles/GN-scraper.py which we don't currently have in tools/license-builder.sh.
If I remember correctly I tried to reference the existing script/put the script in tools but couldn't get the gyp file to call it successfully via <!@pymod_do_main(.... Maybe someone else in @nodejs/gyp or @nodejs/python can advise.

I'm guessing there's a simple fix for the compilation failure with quic enabled on Windows. @nodejs/quic

Restructure the zlib.gyp file based on the upstream gn file, breaking out the files with optimizations that need additional compiler flags. Use a copy of the GN-scraper.py script to reduce the amount of hand editing when the zlib dependency is updated.

Did a quick rebase.

FWIW it appears the createInflate benchmark is the only one that shows a consistent performance regression:
