For various reasons I won't go in to here I needed finer granularity in the Last-Modified and If-Modified-Since HTTPD headers for a project I am working on. Since Linux 2.5.48 the file modification time has a granularity of nanoseconds - here is the quote from the man page:

Sometimes something comes along that truly impresses me. get_iplayer is one of those things. As a UK resident who uses iplayer three or four times a week and a Perl fan get_iplayer really caught my interest. The idea that you can list all of the BBCs iplayer content then download whatever you like to watch whenever you like really did interest me. First I tried downloading it from github but it failed to find updates. Then I noticed it was available as an Ubuntu package and installed it. After that a:

I've just released v0.20 of DBIx::Log4perl. DBIx::Log4perl is a Perl extension for DBI to selectively log DBI methods, SQL, parameters, result-sets, transactions etc to a Log::Log4perl handle. This release fixes a problem where execute_array tuple status was reported at INFO level instead of DEBUG level and adds the DBIX_L4P_LOG_DELAYBINDPARAM constant which delays logging bind_param methods in DBI until the execute method is called.

Recently I've had a spate of issues reported in dbi-users mailing list and direct to me wrt calling procedures in MS SQL Server. I thought it might be worth covering some of the more common ones here.

I've had a laptop stolen! It was a long time ago, I'd paid thousands for it (over £3000, it was a long time ago when laptops were a lot more expensive than now) and I was gutted. To make matters worse I'd not put a BIOS password on it and also this is when I discovered my mis-sold insurance policy only covered £1200. Thank you Skipton Building Society - not. I took it in to work to show a colleague Linux on it and made the mistake of leaving it in my bosses car whilst we went for a drink before going home. Someone got in to the underground car park, broke the window and made off with it - thief - sorry for your window boss. If I'd installed a BIOS password then at least I would have had the small comfort that although not impossible to get around, it would have made matters difficult.

Recently I updated DBIx::Log4perl to handle DBI's clone method. This proved a little troublesome as clone is marked as "likely to change" and I'm not sure any other DBIx's have added clone. The problem I had was that clone does not call connect and all the code I had to add DBIX::Log4perl's attributes into the dbh was in connect.

Over the last few months I've been receiving an increasing number of emails from people experiencing problems inserting date/time/datetime/timestamp values into MS SQL Server specifically although not exclusively. There are a number of MS SQL Server ODBC drivers but the ones I see the most (in no particular order) are a) MS SQL Server ODBC Driver b) MS SQL Server Native Client driver c) Easysoft's SQL Server ODBC Driver and d) freeTDS. I hope to write a more expansive tutorial on this in the near future but until then I hope this blog post will help.

Yesterday I released DBIx::Log4perl 0.18 This principally add supports for DBI's clone method and fixes fetchrow_array ignoring calling context. It also adds a few speedups spotted using Devel::NYTProf, adds logging of connection attributes and fixes a few more minor issues.

Today I released a new development version of DBD::ODBC (1.23_2).

Apologies to the few people waiting on changes but I've been snowed under with work on DBIx::Log4perl, DBI and DBD::Oracle but mostly my day job (which uses all of these modules and a alot more).

It all started when a daemon I am developing hit a job which took too long to run and so it ignored any connecting clients whilst running the job. A long term plan exists to sort this out but it is getting in the way of some test code so I decided to write a small workaround until I am ready to implement the full solution. The workaround seemed so simple I thought it would only take half an hour to do - how wrong I was.
