[PATCH v1 0/2] Fix default macOS build locally and on Travis CI

[PATCH v1 0/2] Fix default macOS build locally and on Travis CI

[larsxschneider]

From: Lars Schneider <larsxschneider@gmail.com>

Apple removed the OpenSSL header files in macOS and therefore Git does
not build out of the box on macOS anymore. See previous discussion with
Torsten here: http://public-inbox.org/git/565B3036.8000604@web.de/

This mini series makes Git build out of the box on macOS, again, and
disables the HTTPD tests on macOS TravisCI as they don't work anymore
with the new macOS TravisCI default image:

[PATCH v1 1/2] config.mak.in: set NO_OPENSSL and APPLE_COMMON_CRYPTO for macOS >10.11

[larsxschneider]

From: Lars Schneider <larsxschneider@gmail.com>

Apple removed the OpenSSL header files in macOS 10.11 and above. OpenSSL
was deprecated since macOS 10.7.

Set `NO_OPENSSL` and `APPLE_COMMON_CRYPTO` to `YesPlease` as default for
macOS. Make it possible to override this and use OpenSSL by defining
`DARWIN_OPENSSL`.

[PATCH v1 2/2] travis-ci: disable GIT_TEST_HTTPD for macOS

[larsxschneider]

From: Lars Schneider <larsxschneider@gmail.com>

TravisCI changed their default macOS image from 10.10 to 10.11 [1].
Unfortunately the HTTPD tests do not run out of the box using the
pre-installed Apache web server anymore. Therefore we enable these
tests only for Linux and disable them for macOS.

I like that you gave an override, but I don't think it works in all
cases:

This is in config.mak.uname, which gets sourced before config.mak (and
ifndef is evaluated at the time of parsing). So it would work to do:

  make DARWIN_OPENSSL=Yep

but not:

  echo DARWIN_OPENSSL=Yep >>config.mak
  make

I think you'd have to set a flag in config.mak.uname, and then resolve
it in the Makefile proper like:

  ifdef DARWIN_OPENSSL
	# Overrides AUTO_AVOID_OPENSSL, do nothing.
  else ifdef AUTO_AVOID_OPENSSL
	NO_OPENSSL = YesPlease
	APPLE_COMMON_CRYPTO = YesPlease
  endif

but that's totally untested.

Good point. I think I found an even easier way to achieve the same.
What do you think about the patch below?

Hi Junio,

the patch above is one of two patches to make TravisCI pass, again.
Could you queue it?

The other patch is [1] which is still under discussion.

Thank you,
Lars

That is much simpler.

I have in the back of my mind a fear that it is harder to unset a make
variable than it is to override it with a new value (which is what you'd
want to do here to turn openssl back on), but I can't seem to come up
with a case that doesn't work. So I am probably misremembering, or just
thinking of something that used to be a problem long ago.

It depends on what you mean by "unset".

If you mean it as per the shell "unset" command, where the variable is
completely forgotten as if it never was set at all, that's tricky.  You
have to use the "undefine" special command which was introduced in GNU
make 3.82 (released in 2010).

But if you just want to set the variable to the empty string, using
"FOO=" works fine for that in all versions of make (GNU and otherwise)
and using all the normal rules (command line override, etc.)

It's not easy to distinguish between a variable that is empty and one
that is actually not defined, in make, so it's a difference without a
distinction in almost all situations.

Specifically I wanted to make sure that

  FOO = bar
  FOO =
  ifdef FOO
  ... something ...
  endif

works as if FOO had never been set in the first place. Which it seems
to, at least in GNU make (and that is the only one we support, for other
reasons).

Yes, it will work.  Confusingly, "ifdef" actually tests whether the
variable has a non-empty value, not whether it's defined:

I don't really mind disabling tests if they don't run on a platform. But
the more interesting question to me is: why don't they run any more? Is
there some config tweak needed, or is it an insurmountable problem?

Using Apache in the tests has been the source of frequent portability
problems and configuration headaches. I do wonder if we'd be better off
using some small special-purpose web server (even a short perl script
written around HTTP::Server::Simple or something).

On the other hand, testing against Apache approximates a more real-world
case, which has value. It might be nice if our tests supported multiple
web servers, but that would mean duplicating the config for each
manually.

I don't know if that is a correct solution.

If I have Mac OS 10.12 and Mac Ports installed, I may want to use
OPENSSL from Mac Ports.

Can't you define `NO_APPLE_COMMON_CRYPTO` in that case? 
I think if you use OpenSSL then you don't need the Apple crypto lib, right?

I've followed what was available at the public-inbox archive, but it
is unclear what the conclusion was.  

For the first one your "how about" non-patch, to which Peff said
"that's simple and good", looked good to me as well, but is it
available as a final patch that I can just take and apply (otherwise
I think I can do the munging myself, but I'd rather be spoon-fed
when able ;-).

I do not have a strong opinion on the second one.  For an interim
solution, disabling webserver tests certainly is expedite and safe,
so I am fine taking it as-is, but I may have missed strong
objections.

Thanks.

I can't really remember what the problem was. I think some apache config
required some module that was not present and I wasn't able to get this
working quickly.

I agree that the real-world Apache test is more valuable and I really want
to keep the Linux Apache test running. However, I don't think many people
use macOS as Git web server and therefore I thought it is not worth the

[PATCH v2] Makefile: set NO_OPENSSL on macOS by default

[larsxschneider]

From: Lars Schneider <larsxschneider@gmail.com>

Apple removed the OpenSSL header files in macOS 10.11 and above. OpenSSL
was deprecated since macOS 10.7.

Set `NO_OPENSSL` and `APPLE_COMMON_CRYPTO` to `YesPlease` as default for
macOS. It is possible to override this and use OpenSSL by defining
`NO_APPLE_COMMON_CRYPTO`.

IMHO, the value in the http tests is not testing the server side, but
the client side. Without being able to set up a dummy HTTP server, we do
not have any way to exercise the client side of git-over-http at all.
And people on macOS _do_ use that. :)

Amen to that.

I however do not know what the universally available simplest dummy
HTTP server would be.  There probably are better alternative than
Apache with distro-customized ways of configuration that we have to
adjust.  

A solution around HTTP::Server::Simple sounds attractive but is it
a realistic alternative or too much effort required?  I dunno.

I'm less concerned about the amount of effort (though I agree it may be
a blocker) than about the fact that it may not behave similarly to real
servers. We have had real bugs and surprises with the way that various
web servers implement things. A few that come to mind are:

  1. Buffering/deadlock issues between the webserver and the CGI (this
     was an issue with Apache, but I don't know about other servers).

  2. The handling of CONTENT_LENGTH with chunked-encoding (this is still
     an issue with IIS).

  3. What happens when you ask for "foo.git/info/refs" and "foo.git" is
     a bundle file (Apache gives you a 404, lighttpd serves the bundle).

Ideally we'd test against a lot of different webservers, but that's
expensive (in CPU, but also in developer time). But I'd guess that
Apache is at least more representative than HTTP::Server::Simple of real
servers in the wild.

So if we had a simple fallback in addition to Apache, I'd be OK with
that. But we still have a problem that (say) people on MacOS would never
actually test against Apache, because it's not supported there.

I was wondering if it takes too much effort to make it behave
similarly to real servers, so I guess we are on the same page.  

Yes, I recall the IIS one raised and discussed at least twice on the
list in the past, and it sounded that we want some solution to that.

That's a bad one.  Do we want a client-side "I am connecting to a
site that knows how to talk smart-http" option or something to work
it around?

The patches had some issues. I suspect the population of people who want
to run a git server on IIS is relatively small. I am content to wait for
somebody who has such a setup to produce a working patch.

It doesn't matter because we don't actually support fetching HTTP
bundles via "git fetch" yet.

But I ran it across the issue and did make such a fix when I was
implementing that feature long ago. See the discussion of "surprise" in
[1] and [2].

Wow, that series is exactly 5 years old today. Have I really been
procrastinating on re-rolling it that long? Yikes.

Well, I haven't seen it from that perspective, yet, but I agree :-)


To all macOS users on the list:
Does anyone execute the tests with GIT_TEST_HTTPD enabled successfully?


There would be an alternative way to approach the problem:
Someone (GitHub?, BitBucket?, GitLab?, ...) could setup a bunch of webservers
with popular configurations and a way to reset a clean test environment. Then 
the TravisCI client tests could go against these servers.

I realize that this idea is probably unrealistic because too much setup and
maintenance work would be required.

Yeah, it seems like it adds a lot of complexity for little gain. Plus it
creates a network dependency on running the tests. I know you care
mostly about Travis, but I am much more interested in all of the people
(developers and not) who run "make test" on their own platforms.

If you did want to have a more real-world network-based test, I think
the right solution is not for GitHub to set up a bunch of mock servers,
but to design client-side tests that hit the _real_ GitHub (or GitLab,
or whatever) and perform some basic operations. OTOH, people running
"master" (or "next", etc) are doing that implicitly every day.

Thanks! This makes "next" pass, again:

BTW: If you want to learn about the build status of "git/git" branches on the
command line then you can use this snippet:

$ branch=next; echo "$branch: $(curl -s https://api.travis-ci.org/repos/git/git/branches/$branch | perl -lape 's/.*"state":"(\w+)".*"sha":"(\w{7}).*/$1 $2/g')"

That is actually a neat idea. We could setup a test repo on each of the major 
Git hosting sites and then the TravisCI run could clone a repo and push
changes to it. That shouldn't take long and would probably be a good real
world test.

The credentials of these repos could be stored encrypted in Travis CI [1].

Where would such a test repo live on github.com? On github.com/git or would
you prefer a separate organization? (no worries, I am not going to tackle this
anytime soon -- too many things in my backlog already).

BTW: I just noticed https://github.com/git/hello-world ... is this legitimate
or did someone hack github.com/git? :)

I think I'd prefer for it to live outside of the "git" organization
entirely, if only because it's credentials will be necessarily less
secure. It would be nice if people could point the suite at their own
user/repo, too, so they can run it outside of travis.

Hmm. I wondered myself. There's no audit record of who created it, but
the creation timestamp is from 2008-07-23, which predates a lot of the
logging. So offhand, I'd say the likely explanation is "Scott Chacon
experimenting".

It's probably worth cleaning out now, though.

That's what I see, too. Apache needs to be configured in some special way 
to make them work and I was wondering if anyone has figured that out
already for macOS...

However, I much prefer Peff's idea to test against real world servers:

This is what I see for 5539:

$ GIT_TEST_HTTPD=1 ./t5539-fetch-http-shallow.sh -v
Initialized empty Git repository in /Users/hvoigt/Repository/git4/t/trash directory.t5539-fetch-http-shallow/.git/
checking prerequisite: NOT_ROOT

mkdir -p "$TRASH_DIRECTORY/prereq-test-dir" &&
(
	cd "$TRASH_DIRECTORY/prereq-test-dir" &&
	uid=$(id -u) &&
	test "$uid" != 0

)
prerequisite NOT_ROOT ok
httpd: Syntax error on line 65 of /Users/hvoigt/Repository/git4/t/lib-httpd/apache.conf: Cannot load modules/mod_mpm_prefork.so into server: dlopen(/Users/hvoigt/Repository/git4/t/trash directory.t5539-fetch-http-shallow/httpd/modules/mod_mpm_prefork.so, 10): image not found
error: web server setup failed


It seems the other failures have the same cause.

Cheers Heiko

Yes, same here.

If we take that out:

I run into other issues:
