Ya I see this...

So I trying to take a little time tonight and figure out what happens.. Could 
use some help.

I currently looking at test/CPPSUFFIXES.py 

This fails at line 107. From what I can tell the test expects output of

C:\Python27\python.exe mycc.py test1.o test1.c

but instead we get 

C:\Python27\python.exe mycc.py test1.o test1.c
Install file: "test1.c" as "test1_c"
Install file: "test1.h" as "test1_h"

This happens because foo.h was changed causing these files to be copied again.

So problems I have with this test.

1) no one would copy headers that depend on a header not passed to the install 
area. I am not sure if we should treat <> different from “” includes. It a 
common practice to use “” for headers in your library and <> for stuff outside 
your library. I don’t this really helps either way
2) the copy/install builder does not generate new file if the source is 
different. What we have here is a good scanner that would do the right thing if 
the “binary” needs to be rebuilt, but redundant is the copy has to happen. The 
issue in a way is that SCons makes the installed test1_c out of date because 
foo.h is out of date, when in fact this is a case in which we would want to 
update logic to care more about the csig of the source being the same as what 
is stored and not doing anything as technically this is correct behavior for 
copy like builders and ignoring that the scanner header is out of date.

I see few solutions to this:

1) we say current behavior is correct and update the test.
2) we make a change to allow a install/copy builder to say the scanner items 
are Required() which remove the Depends() state
3) we change builder to apply a custom sig check for the install nodes to 
ignore that a file dependent from the scanner.
4) remove the scanner from the install builder as we only want to copy files 
that change

I lean toward 4) logic given I how I understand the CCopy builder in Parts 
works. and that the install builder for the most part is a copy builder that 
adds nodes to a list to be used by the Scons version of the packaging builders.

FYI.  The failing tests you listed match the list from June. The action-test.py 
may be new.

  Jason,


  As previously stated in the pull request comments, I expect some tests to 
fail currently because of the recursive header install issue (topic #1): 
<lang>SUFFIXES, HeaderInstall.py.  The other tests may or may not be related.


  There is more value in looking at those tests first.  It may also be valuable 
to go back 3-4 commits to the closest ancestor of the default branch and run 
tests there, so that we can see if some of the tests failed previously.  Also, 
if we think its a problem of the current location of that divergent head, then 
we can see if a rebase fixes some of them.

    That's a SCons fork.  Not an HG branch (in case its a terminology problem). 
 Make sure you are using the CrossLanguage bookmark.

      Jason,

      Are you sure you are using the correct commit revision?

      None of those tests are failing on my Linux distro, and I haven't 
modified any of those tests either.  Plus, tests that I am expecting to fail 
are apparently passing.

        Jason,

        I'm not sure.  I remember that you were helping me look into the 
recursive Install behavior.  Plus, possible parts incompatibility?

        I haven't ran the tests on a windows box at all.  I don't expect 
anything new, but it should be done before it ships :)

          Happy with it*


          Until the review is complete, and I can perhaps get a few more guinea 
pigs to try it out, it's hard to make a concrete projection. I have 3 items 
listed out that need to be given a thumbs up/down at a minimum:


          * Item #1 is still mostly outstanding.  I'm not sure how to address, 
please see the discussion Jason and I started a few weeks ago under the pull 
request comments.


          * Item #2 requires no changes (to my knowledge), but someone with 
more QT knowledge may say otherwise.

          * I may already have most of the patch for Item #3 (IE. no scanner 
for key) based on today's feedback.


          I also still need to request test runs on Windows, and for toolchains 
that I may not have installed or instructions to install them (EG. D).

I would before getting this out as officially earlier than later.

                    Yes, that's how we've done it in the past.  Sounds like 
doing it at the same time as slots would be perfect.



                  Doing this in parallel with the "slots" change sounds good to 
me too. +1


                I'm not opposed to releasing in the same update as slots, but 
since the cross language code reviews haven't been finished, I don't want to 
delay slots since it is ready now.


                The pessimist in me as sees doing two major enhancements in the 
same release as higher risk; I don't foresee any issues, but its worth the 
thought if the release overhead isn't too bad.

                        Gary,

                        For such a change we should bump the second digit?
                        2.4?

                        I agree we should not turn down a change because it 
will cause rebuilds where the past didn't as long as it is now more correct
                        (which it should be with this change).


                  Yes, "forward" is the way to go. ;)


                        Also agree we should be verbose in our notification of 
the impacts of the new change to avoid (as much as we can) "surprises".



                  I think (better: hope) we did a good enough job for the 
"slots" stuff on this. For the scanner changes, I see them more like a fix...so 
a single announcement should be sufficient?

                  Finally, and just in case I haven't done so already, I'd like 
to thank William for all the work he's done on this issue. I couldn't help as 
much as I would've liked, but with Gary's support you tackled this down and 
brought it to a good end. Kudos to you...bravo!



                Truly appreciated.  I have spent a lot of time on this issue 
despite what one might expect from the number of lines of code.

                It was honestly my first time working in a "real" python 
environment outside of scripting, and the SCons code base is rather complex.  
It instills me greater appreciation for the work that has already done.


                I also want to thank everyone here for their help past and 
future, but don't pat me on the back until its done. I might get lazy :)

                  Dirk
