Re: git commit: fix build with custom path - close #COUCHDB-1426
A few hunks in here concern me:
- CPPFLAGS="$CPPFLAGS -I/opt/local/include/js"
CPPFLAGS="$CPPFLAGS -I/usr/local/include"
- CPPFLAGS="$CPPFLAGS -I/usr/local/include/js"
CPPFLAGS="$CPPFLAGS -I/usr/include"
- CPPFLAGS="$CPPFLAGS -I/usr/include/js"
I remember having to add some of these for extremely specific
scenarios. Are we absolutely sure this isn't going to lead to a
regression for some people?
+AC_MSG_RESULT(js flags $CPPFLAGS)
+
This syntax looks weird to me. Its probably right but does anyone know
the rules on when strings need square brackets?
+AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[
+ #include <jsconfig.h>
+ ]],
+ [[
+ #if JS_VERSION == 170
+ // Use spidermonkey 1.7.0
+ #else
+ # Not Spidermonkey 1.7.0
+ #endif
+ ]])],
+ [use_js170=yes],
+ [])
Please don't invent a new indentation scheme for random hunks in a
patch. Also, what's actually being tested here? I'm not seeing how
this would fail unless we're depending on jsconfig.h only existing in
1.7.0 builds, in which case a test compile is not the way to run this
check.
Everything after that hunk looks quite weird to me. I'm fairly certain
we just had a commit that fixes this issue. I don't remember the
details off the top of my head but this is getting into the land of
silly walks with all the bending over backwards to find SpiderMonkey.
At a certain point we might want to just ixnay a lot of this and just
guess at the most common cases and if we can't find a version then we
should just add a configure option.

It should be handled in the js tests part not here.

I don't invent a new indentation scheme actually. I just use the
defult provided by vim.
What it test is getting the version == 170. If it's not equal it
fails. It actually works as expected.

The thing is that the way versions are tested is actually wrong. We
don't assume there could be more than one version in the patch we are
looking and e don't assume that what we want actually is an inferior
version of mozilla 185.
Reproducing the steps I gave allows to reproduce that.
