Interested in helping open source friends on HP-UX?

[Junio C Hamano]

Hello, all.

H. Merijn Brand runs a few HP-UX boxes to help perl5 and other open
source communities, wants help porting more recent Git on these
boxes, running HP-UX 10.20, 11.00, and 11.23, and looking for a
volunteer.  Please contact him directly if you are interested.

Thanks.

No-one. Disappointing :(

I started to work on 2.3.0 on HP-UX 11.23/63 ia64


Did *anyone* ever test with NO_ICONV?
Too many tests fail without iconv

It is *very* hard to decide from the current status if all
remaining failures are related to (Asian) locale failures and (thus)
can be safely ignored (in my environment).

cp uses -P flag, which is unknown to HP's (non-GNU) version of cp

Changing the two occurrences from

make the tests pass (on those systems that have a working rsync)

tar uses z flag, which is unknown to HP's (non-GNU) version of tar
config.mak.uname defines TAR = gtar, but that obviously does not help

work just as well and prevent the breakage

t/t3900-i18n-commit.sh
----------------------
As my HP boxes have *NO* JP or other space eating asian locale stuff
installed, it is highly likely that *anything* dealing with asian
locales will fail. On modern Linux hardware, disk space is cheap. On
most HP-UX boxes disk space is expensive and when having nothing to do
with Asian languages, removing all Asian-related packages is a fast and
cheap way to regain disk space.

Changing compare_with to

compare_with () {
    case "$1$2$3" in
	*eucJP*|*ISO-2022-JP*) true ;;
	*)
	    git show -s $1 | sed -e '1,/^$/d' -e 's/^    //' >current &&

Well, how can we help if we don't even know the limitations of that
platform?

In short, you are putting additional restrictions in by not having GNU
tools around.

> Did *anyone* ever test with NO_ICONV?
> Too many tests fail without iconv

There is iconv the library and iconv the command. With NO_ICONV, many
tests fail for me even on my standard Linux distro. But our tests keep
using iconv the command. The subtests which pass in t3900, for example,
mostly test that certain things fail, for one reason or another...

But we should guard a few tests in case of NO_ICONV, of course, and
probably not use iconv the command in this case either.

"rsync -r -l -o -p -t" would be the proper equivalent. -aH does more for
my rsync. I don't know what HP-UX rsync understands, though.

We can do without z.

So you do have iconv the command, but don't want to link with the library?

Availability of the locales should be covered by a prerequisite, like we
do in t9129.

The "Already"-part is normal output. The rest looks a bit crazy - and

Is that mailinfo erroring out? Do you have those locales?

OK, I'll have to stop fishing in the dark here.

I'm not sure, but I think the original call for help may have been "I
will give you shell access to these boxes if you want to play around".

It seems like we could use

  (cd src && tar cf - .) | (cd dst && tar xf -)

here as a more portable alternative. I don't think we can rely on rsync
being everywhere.

Yeah, that probably was my bad---I didn't make it clear enough that the
request for volunteer from H.Merijn was exactly that.

Thanks; I wasn't even aware that we used rsync in our tests.  We
certainly do not want to rely on it.

Why not "cp -r src dst", though?

I don't think we do.

Grepping for rsync in t/, it is mentioned in three places:

  1. In t1509, we use it, but that test script does not run unless you
     set a bunch of environment variables to enable it.

  2. In a sample patch for t4100. Obviously this one doesn't execute. :)

  3. In t5500, to test "rsync:" protocol supported. This is behind a
     check that we can run rsync at all (though it does not properly use
     prereqs or use the normal "skip" procedure).

> Why not "cp -r src dst", though?

I was assuming that the "-P" in the original had some purpose. My "cp
-r" does not seem to dereference symlinks, but maybe there is something
I am missing.

I have offered to give any serious git developer an HP-UX account, so
one can found out themselves. I can then - hopefully - answer any
remaining question.

> In short, you are putting additional restrictions in by not having GNU
> tools around.

There *are* GNU tools around, and I *can* add other tools. I - of
course - cannot install *all* GNU tools. I don't put serious
restrictions on the wishes of developers. You ask we play. Mostly.

The problem here is that I can configure, build, and test any tool
(git) on my system using every GNU tool I might have available, but
once I convert this build into a package/distribution, and people
around the world download it and expect it to work, it will fail if
the tool (git) depends on available system commands that now do not
meet the needs of the tool (git).

Note that I have put TAR = gtar in config.mak.uname, but it is not
consistently used

HP has no rsync. I installed it myself.
As HP does not have rsync, it does not conflict. If I would install cp
however, I bet many system-tasks could fall over.

I have set SHELL_PATH = /pro/local/bin/bash

The default /bin/sh on HP-UX is almost as bare as the old bourne shell
So, shell related? Likely!

You don't. It was a quick hack from me to see if this was the only
cause of failure for that test

There's a symlink in sub that needs to be preserved.

I'm cooking up a mini-series covering tar/cp -P so far and hopefully the
JP encodings later. Do I understand correctly that for Merijin's use
case on HP-UX, we want

- as few extra tools (GNU...) as possible for the run time git
- may get a few more tools installed to run the test

I still don't have a clear picture of the iconv situation: Does your
iconv library require OLD_ICONV to compile? Is there a reason you want
to disable it?

Failing so many tests with NO_ICONV is certainly not ideal, but I'm not
sure we should care to protect so many tests with a prerequisite.

Merijn, no second j. You can also call me Tux, as that is what the perl
people do just because of that :)

You can require as many GNU tools for testing as you like: I'll install
them. I just need to be sure they are not required runtime. (tar, cp)

No

> Is there a reason you want to disable it?

Yes, if I build a package/depot, and the package depends on iconv, it
is highly likely to fail on the client side after installation, as I do
not control the version of iconv/libiconv installed.

As HP does not have libiconv installed by default, I have experienced
many tools to be unusable after installation because of that dependency.

Another reason is that I built 64bitall, as my CURl and SSL environment
is 64bitall for every other project on these systems (including Oracle
related, which *only* ships 64bit objects on HP-UX) and the OpenSource
repos for HP-UX only ship 32bit software (sad, but true). That implies
that I cannot require libiconv.so to be present on the client side.

I'd like my git to be as standalone as possible

How feasible is it to isolate those tests into separate test files that
people that know to not use e.g. Asian can safely ignore them?

OK, so we should use NO_ICONV on HP_UX then.

We have the prerequisite mechanism for that, and most probably, the
tests are "isolated" already, in the sense that with NO_ICONV, only
trivial setup tests succeed for those test files but all "proper" tests
fail. But I'll check. Need a good test to set the prerequisite, though.

I took a first pass at this. The results are below (and I am hoping one
of you can use it as a base to build on, as I do not want to commit to
doing the second half, as you will see :) ).

It passes NO_ICONV through to the test suite, sets up a prerequisite,
disables some test scripts which are purely about i18n (e.g.,
t3900-i18n-commit), and marks some of the scripts with one-off tests
using the ICONV prereq.

Note that it also has some code changes around reencode_string_len.
These aren't strictly necessary, but they silence gcc warnings when
compiled with NO_ICONV. In that case we do:

  #define reencode_string_len(a,b,c,d,e) NULL

but "e" is an out-parameter. We don't promise it is valid if the
function returns NULL (which it does here). I'm kind of surprised the
compiler doesn't realize that:

  foo = reencode_string_len(...);
  if (foo)
	bar();

is dead code, since the first line becomes "foo = NULL". So that's
optional.

So, on to the tricky parts. Here are the failures that remain:

  1. The script builds up a commit history through the script, and later
     tests depend on this for things like commit timestamps or the exact
     shape of history. t9350 is an example of this (it has one failing
     test which can be marked, but then other tests later fail in
     confusing ways).

  2. The script creates commits with encoded commit messages, then uses
     those both for cases that care about the encoding, and those that
     do not. t4041 is an example here. I think it would be best to use
     vanilla commit mesages for the main body of tests, and then
     explicitly test the encoding-related features separately. I think
     t4205 and t6006 are in this boat, too.

I also tested this on a system with a working "iconv". If we are
building with NO_ICONV, I am tempted to say that there should be no need
to run the "iconv" command-line program at all. But t6006, for example,
does it a lot outside of any test_expect_*. Probably it should be:

  test_lazy_prereq ICONV '
	test -z "$NO_ICONV" &&
	utf8_o=$(printf "\303\263") &&
	latin1_o=$(printf "\363") &&
	test "$(echo $utf8_o | iconv -f UTF-8 -t ISO-8559-1)" = "$latin1_o"
  '

or something, and all of that setup should be wrapped in a
"test_expect_success ICONV ...". Of course that is the easy part. The
hard part is splitting the ICONV setup from the vanilla commit setup so
that the other tests can run.

Hmm. I know we pass other stuff down, but is this really a good idea? It
relies on the fact that the git that we test was built with the options
from there. This assumptions breaks (with) GIT_TEST_INSTALLED, if not more.

Basically, it may break as soon as we run the tests by other means than
"make", which is quite customary if you run single tests.

(And we do pass config.mak down, me thinks, but NO_ICONV may come from
the command line.)

Jeff, you got it wrong. You should do the hard part and leave the easy
part to us!

Thanks anyways, I'll add this to my HP_UX branch.

I did not mention this in earlier mails. When using the HP C-ANSI-C
compiler, MAX_INT is not set.

I had to add
--8<---
#ifndef   SIZE_MAX
#  define SIZE_MAX              (18446744073709551615UL)
/* define SIZE_MAX              (4294967295U) */
#  endif
-->8---

to these files

sha1_file.c
utf8.c
walker.c
wrapper.c

And yes, that could be dynamic and probably be in another header file

It's not quite so bad as you make out. We write the value to the
GIT-BUILD-OPTIONS file during "make", no matter where it comes from, and
load that in test-lib.sh. So:

  make NO_ICONV=Nope
  cd t
  ./t3901-i18n-patch.sh

works just fine (for this and for any of the other options we mark
there).

It won't work for GIT_TEST_INSTALLED, but that is not a new problem.
Fundamentally you cannot expect to test a version built without option X
without telling git _somehow_ that it was built that way.

I suspect GIT_TEST_INSTALLED is not all that widely used, or somebody
would have complained before. But if we really want to support it, I
think the right thing is to bake GIT-BUILD-OPTIONS into the binary, so
that "git --build-options" dumps it. It might also have value for
debugging and forensics in general.

It survives a cd, sure... Now, change your config.mak before the cd and
forget the make. Not everyone does

make -C t t3901-i18n-patch.sh

Though, having just discovered that shell completion works for that
form, too, I may do it more often (and then complain about having to use
GIT_TEST_OPTS ;) )

Yep, that would be helpful in general. I don't think we should worry
about GIT_TEST_INSTALLED too much. Who came up with that feature anyway...?

I think the interesting thing is that it survives running `./tXXXX`
rather than running the test through make.

Yeah, I never use "make tXXXX" myself. But nor would I expect the tests
to respect a version of git I had not actually built. E.g., if you build
with NO_PERL, and then remove NO_PERL from your config.mak but do _not_
actually run "make", should that work? Ditto for NO_ICONV, for that
matter. The tests must match the binary, and the best guess we have
about the binary is the last thing we built.

Adding "git --build-options" would give us a better guess (it may not be
what the user _wanted_ to test, but it is what they _are_ testing).

Clearly a crazy person. :) I am not saying it is a _bad_ idea. Only that
the responsibility to make sure the installed version matches the
current build parameters lies with the user (and for that matter, the
current set of tests; we add new tests that would fail on old versions,
and you cannot mix and match).

So an alternate explanation than "not widely used" is "all of the users
of it are responsible individuals who do not make bogus bug reports to
the list". :)

I think it's safe to say that these mergetool and difftool
failures are not iconv-related.

We have prerequisites that can be used by tests to mark specific
tests as skippable.  It looks like inventing a prereq for mktemp
would be helpful here.

Maybe we don't need a global prereq, but certainly checking
whether mktemp is compliant for our use case could be used as a
criterion for skipping this test.

A further improvement would be to have have test coverage over
the failure scenario to ensure that the expected error message
is reported and that the correct exit code is returned when we
attempt to use a non-compliant mktemp.

I'd be happy to help review changes to this test.

I'm busy this week(end), but I might be able to poke around next
week if you wanted to give me a shell account.

That said, this error is non-fatal for most use cases ~ as long
as you don't set mergetool.writeToTemp then mergetool will work
fine as it will not attempt to use mktemp.

This sounds like another case where a prereq would be helpful.
In this instance it'd be a "readlink" pre-req.

The --dir-diff code should probably be a little more careful
here, nonetheless.

The error about, "fatal: 'difftool' appears to be a git command"
seems like it might be something that can be improved.

It seems like difftool is returning an error code that the
caling code is misinterpreting as meaning, "not able to execute"
vs.  the real situation where difftool simply exited with an
(unexpected) error code.

It seems like we'd want to catch the error within difftool and
exit with a known error code.

In compat/regex/regex_internal.h we have

/* For loser systems without the definition.  */
#ifndef SIZE_MAX
# define SIZE_MAX ((size_t) -1)
#endif

Does this work in your environment?

I think it does:

make
    CC sha1_file.o
    CC utf8.o
    CC walker.o
"walker.c", line 119: warning #4232-D: conversion from "struct object *" to a
          more strictly aligned type "struct commit *" may cause misaligned
          access
                if (process_commit(walker, (struct commit *)obj))
                                           ^

"walker.c", line 124: warning #4232-D: conversion from "struct object *" to a

Hmmh. Did you get these same warnings with the fix you had before? They
don't make feel that confident...
