tools: Have flex and bison mandatory

[XEN PATCH] tools: Have flex and bison mandatory

Posted by Anthony PERARD 1 year, 2 months ago

Both are already mandatory to build the hypervisor.

This will help avoid cases where the *.y or *.l files are been updated
but flex and bison aren't available.

This also remove the way the missing binaries are been handled, with
double-column-rules, which might be an issue sometime.

Adding ".SECONDARY:" to avoid "libxlu_cfg_y.c" been deleted by make
when building the library, and regenerating the file on the first
incremental build.

I'm not sure this is sufficient as a justification. From all we can
tell even pretty old tool versions are okay for kconfig's purposes.
However, pretty recently I've learned that some linker script language
construct used for GNU ld runs into a bug in certain (old) versions of
flex. Use of that construct will then cause an (almost?) infinite loop
in ld. Therefore the question is whether libxlu's uses are immune to
such issues (along the lines of kconfig apparently being).

That said - I'm happy about the change in principle; if so desired we
could simply see if anyone ever runs into an issue, and revert if need
be. Nevertheless I'm not convinced it'll address the problem Andrew
had noticed in CI (and where the consideration to remove the generated
files originated). It is likely to mask the issue in CI (simply
because, aiui, there are no incremental builds done there), but that
won't prevent people running into it on other occasions.

This is odd: How will this "help"? Right now the build ought to fail
(it doesn't, there's merely a warning, which might be easily missed).
With your change configure will fail when the tools aren't there.

These double-colon rules should never have been introduced. Double
colons have a different meaning ("terminal rule") for pattern rules.
In fact they were my initial suspects when looking into that odd build
failure in CI.

While probably okay here, I'd still like to ask: Are you sure you
don't want to specify the files we care about, rather than applying it
to everything (by leaving blank the right side of the colon)?

Indeed, it won't fix the issue.

The scenario I was thinking about is when someone edit the *.l source
file, and try to rebuild without flex been installed. It might take
sometime to find-out that the reason change aren't taken into account is
because flex is missing. At least there's a warning, but it is buried
within the rest of the build log.

After some more investigation, I don't think anymore the double-colon
rules here is an issue.

I think the issue that Andrew saw in the CI with "libxlu_cfg_y.o"
failing to build while "libxlu_cfg_l.[ch]" are been regenerated is
probably because make doesn't consider "libxlu_cfg_l.[ch]" as a group of
targets.

If for some reason we have:
    libxlu_cfg_l.h newer than libxlu_cfg_l.l newer than libxlu_cfg_l.c

Then make seems to take two parallel decision:
    When building libxlu_cfg_y.o:
        libxlu_cfg_l.h is newer than libxlu_cfg_l.l
        -> libxlu_cfg_l.h is up-to-date, start building libxlu_cfg_y.o
    When building libxlu_cfg_l.o:
        libxlu_cfg_l.c is older than libxlu_cfg_l.l
        -> we need to generate libxlu_cfg_l.c first
Then, libxlu_cfg_y.o fails to build because libxlu_cfg_l.h is been
updated do to the parallel build of libxlu_cfg_l.o.

I can easily reproduce the issue with:
    touch libxlu_cfg_l.c; sleep .1; touch libxlu_cfg_l.l; sleep .1;
    touch libxlu_cfg_l.h; sleep .1; make -j
And having "sleep 1" in "%.c %.h: %.l" recipe, between `rm` and `flex`.

I don't know how to properly fix this yet.
Event writing "%.c %.h &: %.l" doesn't work, with make 4.3, which is
supposed to be grouped targets. But that's is maybe fixed in 4.4.

I guess it would be better to specify each targets.

Right, as said - imo this should be (have been) an error. In that sense
your change of course helps because it makes the issue more apparent.

Interesting. In my somewhat similar experiments I found that an issue
exists only when one of the .c files is missing. Things looked to work
properly when both were there, but one was outdated. Clearly that's
yet more surprising behavior than, as you appear to observe, the issue
simply being tied too "needs updating".

Well, in my tests while 4.4 has fixed one issue with intermediate files
affecting the behavior here, the issue we're possibly running into is
still there. I've sent an inquiry to bug-make@gnu.org.

The actual problem is flex and bison output both files at the same time.
One process sees all of its prerequisites are up to do and therefore
proceeds to the next step.  A second process sees an out of date
prerequisite, and starts to run flex which wipes out the prerequisite of
the first process.


Crucially libxlu_cfg_y.o does NOT depend on libxlu_cfg_l.c, therefore GNU
Make is allowed to proceed with building libxlu_cfg_y.o even if
libxlu_cfg_l.c is out of date.

The problem is the rule to update libxlu_cfg_l.c ALSO updates
libxlu_cfg_l.h as a side-effect.


As such libxlu_cfg_y.o needs an order-only dependency (assuming GNU Make
syntax is allowed) on libxlu_cfg_l.c, so the two rules DON'T run in
parallel and cause havoc.

I do not believe this is a bug in GNU Make.  Merely double-output rules
cause precisely this sort of trouble in Make when run in parallel.

Since you keep referring to this: Yes, GNU make syntax is allowed. We
use pattern rules, which themselves are an extension of the original
suffix rules. The issue is that we can't (unconditionally) use stuff
which was added only in newer versions of GNU make. (See ./README
both for a statement on us requiring GNU make as well as one on the
minimum version we expect to be in use.)

According to my reading, an order-only prereq isn't what would help
us here: "Occasionally you may want to ensure that a prerequisite is
built before a target, but without forcing the target to be updated
if the prerequisite is updated." This isn't the situation we're
dealing with, I would say. We want the prereq updating to occur and
the building of the dependent target to be deferred until all the
prereqs were updated.

I suppose it can be viewed both ways: Make has all information to know
that the file _is_ going to be touched, so it _could_ order operations
accordingly.

You could create a parser which handled all the tokenization itself and
only needed the constants for the tokens.  The result would need the
Lexer header (for the token constants), but not the Lexer itself.  In
such case case foo_y.o wouldn't need foo_l.c to be rebuilt if foo_l.h
was up to date.

"libxlu_cfg_y.o" does NOT require "libxlu_cfg_l.c".  What "libxlu_cfg_y.o"
requires is that IF "libxlu_cfg_l.c" (and thereby "libxlu_cfg_l.h") is
rebuilt, it must be rebuilt BEFORE "libxlu_cfg_y.o" is built.

"libxlu_cfg_y.o" needs "libxlu_cfg_l.c" to be built before it, but does
not itself require "libxlu_cfg_l.c" to be rebuilt.

Hopefully this is sounding rather more similar to what GNU Make's manual
says?

Indeed, the syntax of the Makefile implies this, but the parser isn't
intelligent enough to add this extra constraint.  This makes it harder
for humans to write correct Makefiles, but it meets the requirements of
the specifications.  (may also yield faster builds in some situations)

Might this be solved with:

%.c: %.l | %.h

I'm unsure whether order-only dependencies are GNU-make only (there is a
good chance).  There is also the option of using .PRECIOUS

Then upon more reading wouldn't:

%_y.c: | %_l.c

Accomplish the job?  (assuming GNU-make or everyone has copied that
feature)
