[libdbi-users] [ANN] Ingres(R) 2006 driver committed to libdbi-drivers
Hi, Driver is almost complete. Please note the following: - Autocommit mode is enabled by default works. Multi-statement transactions don't work well yet. - Long/blob and Unicode 'national character set' column types not supported yet, but all other Ingres types are supported including DECIMAL and MONEY. More information in driver documentation files. Tested with Ingres(R) 2006 Community Edition 9.0.4 for Linux/x86, on Gentoo. Ingres is a mature RDBMS now available under both commercial support and GPL terms. Particular strengths are in query optimisation, partitioning, security/auditing and clustering. More information on Ingres can be found here: http://ingres.com/products/ Prod_Ingres_2006.html --Toby ___ libdbi-users mailing list libdbi-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libdbi-users

It seems (from another project I'm on, at least) that the tarball is always woefully out of date. My advice - go ahead and make a new release. Well, we'd have to move to subversion first in order to make use of SVN tags. I'm afraid that releasing SVN tags instead of tarballs will deter end-users who just need to satisfy some application dependency. A tarball is something familiar to non-technical Unix/Linux users, whereas subversion is not. Package maintainers are also used to build from tarball releases. Besides, if I find the time to bless a subversion revision with a stable tag, most of the work is done anyway. I can just as well build the tarball and upload it. This takes just another cup of coffee's amount of time. Mostly agreed. The other project's problem might be that the process of preparing the tarball is not documented and is done by one guy; also there is a trickle of commits, so somebody has to decide when a release is appropriate. The last tarball happened to be made at a very bad time (and was not updated yet), so this decision process failed us. Infrequent tarballs mean that, as I said, they're ridiculously out of date with respect to trunk. (libdbi seems more in maintenance than new development or frantic bugfixing, so it's not really the same case as that project.) I stopped using tarballs in my own projects some time ago, it was only a source of problems. While we're at it: how do other developers and users feel about moving libdbi development to subversion? Is it worth the hassle? Assuming I'm included in other: My vote is yes, I'd feel more comfortable with Svn. In answer to Claudiu: Why don't you release SVN tags and make tarballs, also? It's a good idea to have a tag in SVN... ie: if you want to make a quick diff from the previous release version to trunk? Tag *must* be done when a tarball is made, I don't see that as optional. --Toby regards, Markus -- Markus Hoenicka [EMAIL PROTECTED] (Spam-protected email: replace the quadrupeds with mhoenicka) http://www.mhoenicka.de - Take Surveys.

No; you are using an expression, not the column, so the result type is indeed BIGINT, as Markus surmised (his explanation was correct, as far as I can determine).

Re: [libdbi-users] dbi_result_get_string_idx fails on VARCHAR COLLATE 'binary'
On 18-Jan-10, at 3:47 AM, Markus Hoenicka wrote: Toby Thain t...@telegraphics.com.au was heard to say: This is probably driver dependent. IMHO the first check would be to see if the unexpected reversion to binary type is occurring within libdbi or in libmysqlclient (or mysqld). I bet it is. The mysql driver uses some weird check (in _translate_mysql_type) to find out whether or not a field is binary. Unless I'm dense the code in question may actually cause other problems as well, I have discussed this issue with Vikram on #mysql and IMHO it is wrong in concept for a collation change to affect column type: As it is not concerning the contents of the field but merely interpretation. Naturally he didn't expect to have to change his code. But then perhaps the driver writer held a different opinion. so I'd like to ask everyone with some MySQL knowledge to have a look at it.
