We currently publish the pdb, e.g. https://nodejs.org/dist/v10.9.0/win-x64/node_pdb.zip so this is semver-major?

which is only run on the CI for releases (not for regular PR's).

Ohh. This generates a .pdb file but only a single one during linking.

This will exhaust the memory available in some machines (including our CI). Ref 6cfedf0 and #12184 (comment) . I tested this extensively when I made this change, to find the best combination that uses a reasonable number of threads, and this was the best. CL will use one thread for each processor, but since some of our projects are quite small this helps a lot. If we did it the other way around, not limiting here and limiting in CL, V8 would keep compiling long after everything else finished.

On my 4 CPU box this does not affect compilation time.

I'll continue testing this, but meanwhile I'll remove this from this PR.

+      'msvs_disabled_warnings!': [4244],


I didn't test yet, but this looks quite nice. Is it possible to simply set a much lower warning level for deps?

I've been thinking about that, the problem is common.gypi is used by node-gyp so I didn't want to make a big change without further testing.

This was needed in L482 as well

I didn't test yet, but this looks quite nice.

output is filled with:

d:\code\node\src\node_internals.h(321): warning C4244: 'argument': conversion from 'const uint64_t' to 'const NativeT', possible loss of data

Could you describe this a bit more? Why are these required to re-enable ninja builds?

Could you describe this a bit more? Why are these required to re-enable ninja builds?

'DebugInformationFormat': 1, # /Z7 embed info in .obj files
That's to enable clcache (https://github.com/frerich/clcache#how-clcache-works)
Merging the msvs_disabled_warnings, and adding 4244 to all targets, except node and
node_lib
removing the \lib\ prefix from /WHOLEARCHIVE:<(PRODUCT_DIR)\\lib\\:
1. It's unnecessary, WHOLEARCHIVE just needs the name of the library, not it's full path
2. when building with ninja (instead of MSBuild) the libraries are outputted to: <(PRODUCT_DIR)\\obj\\, so having a wrong full path breaks linking.

joaocgreis · 2018-09-08T00:43:21Z

This looks mostly good. @refack just two notes about the commit messages:

build,win: enable clcache: can you reword this to describe what it actually does? Something like build,win: generate a single PDB at link time and then mention clcache in the description.
build,win: unify warning exclusion: Focusing on the removed warning makes more sense to me here, something like: build,win: remove C4244 only for deps.
