Hi, The last few days I have payed some attention to our Travis-CI integration. Good news is we can now run our unit tests based on google test (thanks to John as well for some extra fixes).
The bad news is my csv-import work fails to build on travis while it builds just fine on my local system. The most recent build failure can be seen here: https://travis-ci.org/gjanssens/gnucash/builds/191881753 This has been failing for a while, even before fixing the gtest stuff. My investigation seems to suggest the issues stems from using a different version of boost on my system (1.60.0) versus the one used on travis (1.54.0). The failure is in this line: if ((m_deposit == boost::none) && (m_withdrawal == boost::none)) with both m_deposit and m_withdrawal being of type boost::optional<gnc_numeric>. It appears boost 1.54.0 doesn't know how to run this comparison and the boost::optional revision history suggests this was addressed in version 1.56.0 [1]. Since our boost baseline is still 1.53.0, I'm looking for ways to handle this differently. gnc_numeric is a C struct. My csv-importer work however is all in c++, so why not use the underlying c++ code of gnc_numeric directly, right ? So I am working my way through this and have some questions about this. 1. I assumed the C++ equivalent of gnc_numeric would be GncNumeric. However this appears to be wrong assumption. GncNumeric is only defined as an alias inside gnc-numeric.cpp and hence not exposed at all to the outside world. Is new c++ code not supposed to use GncNumeric ? Should GncRational be used directly instead ? 2. I continued with GncRational for now. However this seems to implement only fairly limited subset of the functions in gnc_numeric. For example there is gnc_numeric_mul and GncRational::mul. The former takes two extra parameters (one for denom preference and one to tell how to round). GncRational::mul on the other hand takes a denom object as second parameter which encapsulates all that information in addition to the two objects we're about to multiply. I'm not sure how I should use this. Should each consumer of the GncRational class each time build the denom object itself and then call the GncRational mutators ? That looks like a lot of code overhead. How about an overload for these mutators that takes the denom and round type directly as gnc_numeric_mul does ? Or is there another way to use this I didn't figure out yet ? 3. While studying the GncRational code I noted it has doesn't specify the pure constructor "GncRational()", instead leaving this up to the compiler to generate if necessary. That compiler default would create a GncRational with m_num = 0, m_denom = 0 and m_error = GNC_ERROR_OK. I would consider m_num = 0, m_denom = 1 and m_error = GNC_ERROR_OK a better default value for GncRational. A particular reason not to implement that ?
