build,meta: bump gcc on travis #23778

refack · 2018-10-20T02:33:39Z

The version of clang provided in the Travis linux image uses
libstdc++4.8 whice is below our minimal supported version.

Switching to make test -j1 is to avoid races during the test cycle
causes by the main target being "unstable", that is it always builds
some files, and relinks the binary, which is used by the test procedure.

Refs: #23733

I’d prefer to undo this unless it’s actually causing trouble on Travis – I don’t think we’ve seen this so far.

It makes the tests consistent with JEnkins, but I'll do it in another PR

.travis.yml

-        - ./configure
-        - make -j2 V=
+        - CC='ccache gcc-4.9' && CXX='ccache g++-4.9' python configure.py --verbose
+        - CC='ccache gcc-4.9' && CXX='ccache g++-4.9' make -j2 V=


Maybe set these using export CC='ccache gcc-4.9' && CXX='ccache g++-4.9' on the first line of install:, and then leave these lines as they are?

Also, I’d prefer to keep ./configure – firstly, the .travis.yml of a project is sometimes used by devs to figure out how to build it, because it’s usually much more to-the-point than build instructions, and secondly that way we simply test more code than without it (namely the contents of configure).

I'm suspicious it's not behaving as we expect (hence it's using GCC over clang), so I'd rather has it explicit (like in Jenkins).

Ack on the ./configure

From a quick google search, it seems like the error message is a clang one.

From a quick google search, it seems like the error message is a clang one.

So it might be just an stdlibc++ issue?

addaleax · 2018-10-20T03:11:09Z

@refack My guess is that it might be the gcc-provided libstdc++ 4.8 not playing along well with clang? Could be totally wrong on that one, though.

(I also don’t remember the reason for picking clang in the first place, tbh.)

refack · 2018-10-20T03:14:45Z

I also changed the output generator from

make -j2 V=
make -C out BUILDTYPE=Release V=
make[1]: Entering directory `/home/travis/build/nodejs/node/out'
  CXX(host) /home/travis/build/nodejs/node/out/Release/obj.host/v8_libbase/deps/v8/src/base/bits.o

to

$ make -j2 V=1 | sed -e "s/'.*\$//" -e "s|$PWD||g"
make -C out BUILDTYPE=Release V=1
make[1]: Entering directory `/out
  ccache g++-4.9 -o /out/Release/obj.host/v8_libbase/deps/v8/src/base/bits.o ../deps/v8/src/base/bits.cc

  ccache g++-4.9 -o /out/Release/obj.host/v8_libbase/deps/v8/src/base/debug/stack_trace.o ../deps/v8/src/base/debug/stack_trace.cc

(this is planned to change in Jenkins as well nodejs/build#1517)

addaleax · 2018-10-20T03:31:10Z

@refack One thing I’m noticing here is that the extra apt install took about a minute in https://travis-ci.com/nodejs/node/jobs/153110829 … not the end of the world, but something we might want to consider?

lpinca · 2018-10-20T05:48:03Z

.travis.yml

        - ./configure
-        - make -j2 V=
+        - make -j2 V=1 | sed -e "s/'.*\$//" -e "s|$PWD||g"


It seems nodejs/build#1517 is still being discussed. I'm not a fan of this change, can we revert it?

One thing I’m noticing here is that the extra apt install took about a minute in travis-ci.com/nodejs/node/jobs/153110829

But for some reason total was 13m
and other job took 14m

While currently the jobs (using clang) take 15m+
