Can you test with the current head of the maint branch ?

A commit has been merged recently that should allow to build against a system installed shared library version of google test/mock.

I installed googletest and ran (from the main branch as of a couple minutes ago):

CXXFLAGS=-Wno-deprecated-declarations cmake .. -DALLOW_OLD_GETTEXT=ON -DWITH_AQBANKING:BOOL=OFF -DWITH_SQL=OFF
make

The build succeeded, so that's good.

I then tried running the tests (I hadn't done that before) and it complains about lots of missing programs and fails a lot of tests. I used "make test".

E.g.
Unable to find executable:
.../gnucash/build/bin/test-transaction-voiding
.../gnucash/build/bin/test-recurrence
.../gnucash/build/bin/test-business
.../gnucash/build/bin/test-employee
.../gnucash/build/bin/test-vendor
...

Then:
24% tests passed, 78 tests failed out of 102

'make test-sx' succeeded. So I looked for another test target and found 'make check':

make -k check is otherwise successful and I then see:

Errors while running CTest

I'll let you decide how successful this is and if and how many bug reports I should file :)

Please document the proper way to run tests.
Btw, https://wiki.gnucash.org/wiki/Testing still mentions the autotools way to add tests (in the Legacy Tests section).

Yes, make test just runs the tests without building them first, so unless you've already run make check the bulk of the tests are expected to fail.

The link error suggests that the installed googletest library (libgtest.so?) is missing some symbols.

For the other tests, you now need to analyze the test failures and figure out if they're bugs in GnuCash or something to do with your installation. The test output is in two files in Testing/Temporary; LastTest.log is usually the more useful. The tests can also be run individually, they're all in bin. Running in the debugger (after doing a debug build, of course) is often helpful to understanding a failure.

(The automatic trace detector put some non-trace information in the trace attachment.)

For the first, before the backtrace there will be a dump of the command. Two variables in that dump are significant, GUILE_LOAD_PATH and GUILE_LOAD_COMPILED_PATH. What are they set to?

For the second, your distro has borked boost::date_time to return the wrong value for the date formatting parameter %Y, returning a 2-digit year instead of the specified 4-digit year. No need of a backtrace, the test result tells you exactly what's wrong.

For test-exp-parser: No, I pasted the complete output of starting it from the commandline directly. Should I manually set up some environment variables?


As for the second, if printing %Y was broken, all the tests would fail, not just this one, so it must be something else, perhaps locale-related.

Yeah, the expression parser is in Scheme so it needs guile and guile needs some help finding its pieces, particularly in the build environment. The easiest way to get there is to copy the command from LastTest.log.

Ah, good point, though not "all the tests" because that's a glib test and it stops at the first failure, but it would have failed much earlier. You're right, that test is of the date format set by the locale. In that particular case it comes from /usr/share/locale/en_US/LC_TIME. On MacOS (what I have handy at the moment) it's %m/%d/%Y. That seems pretty common, but the 2.6 version of the test, which used GLib's GDateTime class, used g_date_time_format() to get the comparison value instead of hard-coding it. The test program is C rather than C++ and I took the lazy way by hard-coding the string since it works on the Linux distros that we test against as well as MacOS. I'll have to find a less-lazy way to generate the expected string.

Back to test-tx_import: All of the other google-test based tests compiled OK and most passed, so something's up with that one test. Does <builddir>/common/test-core/libgtest.a exist?

Ah, sorry. I didn't follow your advice for looking at LastTest.log earlier.

As for test-tx_import:
The file does not exist, no.

There have been several bug fixes in our build system. What's the current status of this issue ?
Which tests continue to fail when run under current maint ?

By the way I have recently found a more interesting way to run individual tests:
ctest -V -R <test-name>

That will ensure the test is run in the proper environment. -V will print more details while testing

With today's maint HEAD I see, using "cmake -DWITH_AQBANKING=OFF -DALLOW_OLD_GETTEXT=ON  -DWITH_SQL=OFF -DGUILE_EXECUTABLE=/usr/pkg/guile/2.2/bin/guile  -DGUILD_EXECUTABLE=/usr/pkg/guile/2.2/bin/guild ..":

Hope this helps!

The first one is going to take some debugging. The expression parser is supposed to indicate the position of the invalid character (the ç) but it's indicating the end of the string instead. Since it works on all of the OSes we regularly build on I'm afraid it's up to you to debug it on NetBSD.

Looks like NetBSD's nl_langinfo returns %y instead of %Y for US date format and that test doesn't account for the possibility.

The locale exception seems like a hole in the C++ standard library. Does NetBSD have its own or does it use gcc's? It would be helpful to have a stack trace (ideally with debug symbols) for both that and the gnc-timezone exception.

The link failure in test-tx_import is puzzling. Try building it with VERBOSE=1 to see the command line (if you'd use ninja it would do that for you without being asked and generally be faster).

When I run 'ninja check' in a loop until I get at the end:

Is something wrong with the googletest package?

NetBSD does have its own locale implementation, related but not identical to the FreeBSD one.

Can you point me to the relevant code for the exp-parser issue?

Is nl_langinfo() %y/%Y a bug compared to a standard (link?) or just an unexpected non-standardized difference?

GTest: Looks like the libraries are linked in the wrong order, with libgtest.a before libgtest-main.a. That's controlled by ${GTEST_LIB}, used everywhere. It doesn't make sense that it would break in just that one test.

The expression parser code is in libgnucash/app-utils/gnc-expparser.c

You'll need a debug build to figure that out as well as for the gnc-timezone and gnc-numeric exceptions.

For the gnc-timezone exception we need to know what file it tried to open, so rather than another backtrace go to the find_tz_file frame (it was 6 in the backtrace above) and look at the contents of tzname. If it's a relative path, maybe $TZDIR isn't set or is wrong in your environment, so check that. See if you can find the tz file.

The gnc-numeric failure may be because that test tries to set fr_FR.UTF8 as the locale.   Set a breakpoint on gtest-gnc-numeric.cpp line 213 and when that's hit set another on __cxa_throw. That will stop on the throw. Note that there might be two; if NetBSD doesn't define fr_FR.utf8 it will throw once and catch it; if it also doesn't define fr_FR it will throw again from the catch. Note that C++ localization is somewhat separate from C localization, which might explain why the localization tests for test-gnc-numeric.c pass and this one throws.

Reversing the library order fixes a test, so please switch these two around (for whatever reason that improves tests...).

but it didn't fix the test.

Check with the NetBSD C++ Standard Library devs to find out if they support std::locale("fr_FR.UTF8"). 

Is $TZ set in the environment? If not, try that. It's a hole in the implementation, if it's not set it should either throw a different exception ("No timezone!") or default to UTC.

The ';' characters in the string you passed to gdb break it up into different logical commands in bash, so the variable settings are out of scope when the interpreter gets to gdb. ISTR you use csh but I don't remember how it handles inline environment variables. The safe way to set them is to start gdb and then set them inside of gdb, e.g.
gdb> set env GNC_UNINSTALLED YES
...

Or you can stick them in a script file and include `-x filename` on the gdb command line or say `source filename` at the start of your gdb session.

I pushed your GncAddTest.cmake patch.

Ok, so the locale problem seems to be a bug in g++ (7.4.0 nb3 20190319) as used by NetBSD, see https://gnats.netbsd.org/54411

As for the timezone test, when I set TZ to "UTC+2" or "CEST" I get

terminate called after throwing an instance of 'std::invalid_argument'
  what():  The timezone string failed to resolve to a valid filename

and in frame 6:
(gdb) p name
$2 = (const std::__cxx11::string &) @0x7f7fffbbfbf0: {static npos = 18446744073709551615,

    _M_local_buf = '\000' <repeats 15 times>, _M_allocated_capacity = 0}}

When I set it to UTC, I get:

Is there a simple c++ I can use to test the C++ timezone implementation in NetBSD (since I guess that is what you'll ask next? ;) ).

As for test-exp-parser, I put the variables in a file and sourced it in the gdb session, verified that they were set (with "show env" in gdb) but I get the same backtrace:

The NetBSD bug you pointed at isn't right, your libstdc++ is throwing when creating the locale; the bug user is getting a fr_FR locale and expecting a single character thousands separator while the NetBSD libstdc++ uses U+00A0, which is 2 characters in UTF-8. That test may still fail once you get the locale problem sorted.

I noticed this path in the backtrace just now: 
/disk/6/archive/foreign/src/external/gpl3/gcc/dist/libstdc++-v3/src/c++98/localename.cc
That's the gcc stdlibc++, the sources for which are at https://github.com/gcc-mirror/gcc/tree/master/libstdc%2B%2B-v3. But the actual throw is in frame 2 and the path is just c++locale.cc. That's not part of libstdc++, where does it come from? 

Timezones should be specified either as a filename from your zoneinfo directory (normally /usr/share/zoneinfo) or a POSIX timezone string. For UTC+2 you might use "Etc/GMT+2" or "Europe/Berlin" as filenames or "CEST+2" as a POSIX string. The string "UTC" is reserved for UTC.

Is "zdump" available on NetBSD? If it is, please run `zdump America/Los_Angeles` and report the output.

The guile segfault is actually in bdwgc, aka Boehm garbage collection. FWIW I'm able to debug test-exp-parser on Debian testing without any problems. BDWGC doesn't do releases AFAIK, can you figure out what git sha1 you have?

One point that came up in the c++ discussion is that in the test program, output is of type 'std::ostringstream'. However, for a UTF-8 locale a wide stream is needed because the thousands separator does not necessarily need to be a valid char. In the case of the french locale, it's a non-breaking space (0xC2A0).

As for timezone:

"set env TZ=America/Los_Angeles" works:

# zdump America/Los_Angeles
America/Los_Angeles  Sun Jul 28 12:14:35 2019 PDT

I assume that bdwgc is part of boehm-gc, which does do releases, I have 8.0.4 installed, which is the current stable release according to http://www.hboehm.info/gc/

I don't see a c++locale.** file in my NetBSD source tree, so I'm stumped on that one.

You and whoever you were discussing this with need to go study up on Unicode. UTF-8 is a multi-char encoding, not a wchar_t one. Non-breaking space U+00A0 and its UTF-8 encoding is 0xc2 0xa0, two chars.

For test-gnc-timezone, please debug and set a break on line 54. When it stops do
  p tz->std_zone_abbrev()
  p tz->dst_zone_abbrev()

You might also run
  zdump -v America/Los_Angeles | 2012
from a command line just to make sure that your zone file isn't weird.

Looks like c++locale.cc is a build-time soft link in libstdc++:
https://github.com/gcc-mirror/gcc/blob/master/libstdc%2B%2B-v3/src/c%2B%2B98/Makefile.am#L92

I suspect that it's symlinking https://github.com/gcc-mirror/gcc/blob/master/libstdc%2B%2B-v3/config/locale/generic/c_locale.cc. That does indeed have a throw at line 227, with a comment above it:

If I'm right, that means that NetBSD is like MinGW, C++ localization isn't supported. We worked around that by using boost::locale in gnc-numeric.cpp but since we don't try to test on MinGW I never fixed the test. Guess I need to do that.

Yup, boehm-gc. The crash reported in the stack trace is at
https://github.com/ivmai/bdwgc/blob/v8.0.4/os_dep.c#L1004, where it's trying to dereference result. You could examine the value of result after the crash, but even with that I wouldn't know how to proceed. I'm afraid you're going to have to use old-fashioned printfs in libgnucash/app-utils/calculation/expression_parser.c. I suggest building a little debug program, something like

#include <gnc-exp-parser.h>
int main (int argc, char** argv)
{
    char *error_loc = NULL;
    gnc_numeric result = {0, 0};
    gnc_exp_parser_init();
    gnc_exp_parser_parse ("1 ç", &result, &error_loc);
    assert(error_loc == 2); 
    exit 0;
}

That gets guile out of the way.

As for locale support in libstdc++ on NetBSD: In the bug report I've been referencing, there's been progress on this issue, better locale support is currently being turned on. NetBSD 8 and older will not get it though.

int main (int argc, char** argv)
{
    char *error_loc = NULL;

    printf("result: %p, error_loc: %p\n", result, error_loc);
//    assert(error_loc == 2); 
    exit (0);
}

(error_loc is a pointer and 2 is an integer, so I commented this out)

and this compile command line:

gcc -g -O0 -DHAVE_SCANF_LLD=1 -I ../libgnucash/app-utils/ -I ../libgnucash/engine `pkg-config --cflags glib-2.0` -I . test.c  -Llib/gnucash  -Wl,-Rlib/gnucash -lgncmod-app-utils

Do I need environment variables set for the scm load path?

Forgot to mention, for the timezone test, I did set the TZ in gdb. I think it was your example:
set env TZ=America/Los_Angeles

There's nothing to be done about localization, unfortunately. I mis-remembered about the Win32 workaround: boost::locale doesn't work either though for different reasons. We've simply disabled C++ localization on Windows. I expect the same will happen on NetBSD until std::locale gets sorted out there.

Rats, I didn't realize that gnc_exp_parser_init() requires scheme. It looks like expression_parser.c and gnc-exp-parser.c are too tightly coupled to be able to create a stand-alone program for gdb, and starting up guile doesn't work in GDB on your system so that tack won't work.

I think you're going to have to just skip those two tests along with the two GncNumeric::operator<< tests that depend on std::locale. Is there something like __NetBSD__ defined that you can just #ifndef them away?

As for the timezone test it seems that IANAParser::IANAParser(fileblock) is somehow getting the wrong offset for America/Los_Angeles so it's getting the DST abbreviation and UTC offset for the base one. Of course that's the only one that's tested so it might be wrong on all of the zone files. It seems very unlikely that NetBSD would have their own zone files so I'm puzzled how that could happen.

No that last bit is wrong, several TZs get tested and only that one is goofy. Weird.

I think it'd be good to fix the low-hanging fruit:
* set TZ to something valid when running the timezone test
* fix the year 2-digit vs 4-digit issue

C++ locale support will hopefully get better in NetBSD really soon now.

I would not disable the tests, I don't think that helps.

Can this bug ticket be resolved?

Closing, the OP seems to have lost interest. If someone comes along who wants to revive this--on the current maint HEAD--by all means reopen it.
