[PATCH liburing v1 0/2] SPDX fix and .gitignore improvement

[PATCH liburing v1 0/2] SPDX fix and .gitignore improvement

[Ammar Faizi]

Hi Jens,

Two patches in this series. The first patch is SPDX-License-Identifier
fix. The second patch is a small improvement for .gitignore w.r.t. test.

When adding a new test, we often forget to add the new test binary to
`.gitignore`. Append `.test` to the test binary filename, this way we
can use a wildcard matching "test/*.test" in `.gitignore` to ignore all
test binary files.

Goals:
  - Make the .gitignore simpler.
  - Avoid the burden of adding a new test to .gitignore.

I do like the idea of not having to keep fixing that gitignore list.

Hmm.. weird... It builds just fine from my end.
Can you show the full commands?

OK, it now makes sense to me.

These pthread stuff are appended for the test binary files without "*.test" suffix.

35fa71a030ca-test: override LDFLAGS += -lpthread
232c93d07b74-test: override LDFLAGS += -lpthread
send_recv: override LDFLAGS += -lpthread
send_recvmsg: override LDFLAGS += -lpthread
poll-link: override LDFLAGS += -lpthread
accept-link: override LDFLAGS += -lpthread
submit-reuse: override LDFLAGS += -lpthread
poll-v-poll: override LDFLAGS += -lpthread
across-fork: override LDFLAGS += -lpthread
ce593a6c480a-test: override LDFLAGS += -lpthread
wakeup-hang: override LDFLAGS += -lpthread
pipe-eof: override LDFLAGS += -lpthread
timeout-new: override LDFLAGS += -lpthread
thread-exit: override LDFLAGS += -lpthread
ring-leak2: override LDFLAGS += -lpthread
poll-mshot-update: override LDFLAGS += -lpthread
exit-no-cleanup: override LDFLAGS += -lpthread
pollfree: override LDFLAGS += -lpthread
msg-ring: override LDFLAGS += -lpthread
recv-msgall: override LDFLAGS += -lpthread
recv-msgall-stream: override LDFLAGS += -lpthread

I don't know why my linker doesn't complain about that.

What about appending -lpthread to all tests and remove all of these
override stuff? Are you okay with that?

Or do you prefer to append -lpthread for only test that needs pthread?

Nah I think that's fine, also saves some hassle when you add a new test
that does use pthread.
