Something better has finally come along: ctrl-tab.  It is as simple as LastTab…only prettier.  It apparently is slated to be included in Firefox 3.1.  Very nice.

(It appears that LastTab has been upgraded to work with 3.0 finally.  I’m a little disappointed I’m only finding out about this now.  I had added the writers blog to my Reader with the sole intent of being able to get the updated extension on its release date…but no!  No announcement was made by Timothy Humphrey on this blog.  For months now I’ve been reading his mumbo jumbo posts for naught!  Bah!)

org.dbunit.dataset.NoPrimaryKeyException: COHORT_MEMBER

In the Cohort mapping file the cohort_member table is mapped like any hibernate collection:

<set name="memberIds" cascade="none" lazy="true" table="cohort_member">
    <key column="cohort_id" />
    <element column="patient_id" type="integer" />
</set>

It looks normal enough.  Cohort.memberIds is a list of integers defined by the cohort_member table.

Hibernate automatically creates the schema in our test hsqldb because we have hbm2ddl set to “auto”.  The problem arose here because hibernate wasn’t creating a dual primary key on the member_ids table.  Digging through the code, I found that Hibernate only assumes the primary keys are the columns that set to “not null”.

The corrected mapping with both columns set to be not-null:

<set name="memberIds" cascade="none" lazy="true" table="cohort_member">
    <key column="cohort_id" not-null="true"/>
    <element column="patient_id" type="integer" not-null="true"/>
</set>

Now hibernate creates the table with primary keys and hsql is happy again.

Of course she didn’t have any backup solutions, so it was looking like her data was gone forever.

She cries, “Unacceptable!”

I retort, “But its expensive!”.  I cry.

So I do some googling for hard drive recovery reviews and companies.  I call a few and they all say it’ll be in the thousands of dollars.  So I turned to my trusty friend, ebay.  I found one company called Hard Drive Savers offering invasive recovery it for only $300.  (I had taken the top off my drive already and saw it was a hardware problem, so I knew I needed invasive).

I was skeptical, so I did some more googling to get some background on HDDSavers.  I found relatively few comments on them, but all were good.  So off went Meghan’s hard drive.

Lo and behold, a week later a dvd arrived with the contents of the folders she needed!  John over there at hddsavers came through!  I highly recommend them for anyone needing to recover data from a dead hard drive.

Having this method was useful for two reasons:

1. A test like CreateInitialDataSet that is meant to be configured and run alone.  If this test sees that its being run in a group, it returns early and doesn’t actually run the test
2. The module tests needed to have the application context refreshed before running.  To do this, I made the previous test mark the context as “dirty” so that the test directly following it would have a fresh app context.

There were actually two separate solutions:

1. All tests extend BaseContextSensitiveTest for convenience methods and setup.  Every junit class will invoke this class and its constructor.  By adding a static variable loadCount and incrementing that in the constructor, I am able to know how many tests have been run up to that point.
2. The application context doesn’t need to be marked as dirty.  The dummy method could actually be removed without replacement.

I really should have jumped to that last one first.  Googling for my second thought gave me nothing useful.  However, simply adding “eclipse” to my search term brought up the Metrics plugin as the first result!  The Metrics plugin counts all different types of things.  Lucky for me, “number of methods” just happens to be one of them.

To get the counts working for you, follow these easy steps:

1. Add http://metrics.sourceforge.net/update to eclipse as a plugin update site
2. Turn metrics on for your project:
   1. Right click on the root of your project in Package Explorer view
   2. Choose Properties–>Metrics–>Enable Metrics
3. Do an Eclipse clean rebuild
4. Click on the root of your project in the Package Explorer
5. Open the “Metrics” view

These are the relevant statistics from the OpenMRS project:

The second api/web are from the test package.  We have a lot of work to do to catch our total number of unit test methods up with our number of api methods.

I’ve also uploaded the entire OpenMRS metrics output.

I managed to steal some bandwidth at the hotel at 2AM a few nights ago and posted my pictures from the safari to Hluhluwe that James Egg, Jacob Brauer, and I went on.

We’re sitting in the lounge in Johannesburg now (thanks Paul!), I promise to post a few more thoughts from the conference over the next few days.

(As a side note while I’m thinking about it: The new logo is really growing on me. Chris Seebregts made heavy use of it at the conference. He even made up some pretty slick black t-shirts using it that he gave away to all the attendees.)

For posterity’s sake, I’m going to write my solution here.

easy_install mysql-python

I received this error when trying to install the MySQLdb-python module into python on centOS:

_mysql.c:2808: error: expected declaration specifiers before ‘init_mysql’
_mysql.c:2886: error: expected ‘{’ at end of input
error: Setup script exited with error: command ‘gcc’ failed with exit status 1

The fix I remembered.  I just had to install the python development packages:

yum install python-devel

I then had another very odd and strangely familiar error:

In file included from _mysql.c:35:
/usr/include/mysql/my_config.h:15:28: error: my_config_i386.h: No such file or directory
error: command ‘gcc’ failed with exit status 1

Googling around gave me nothing helpful…in fact the results looked strangely familiar as well.  I couldn’t remember the solution to this one though.

Eventually, I actually read the error message and realized that our new vm isn’t an x64 box.  For some reason there was a my_config_x64.h file in /usr/include/mysql but there wasn’t a my_config_i386.h.  Luckily, that file was present on the old server. Copying that file from /usr/include/mysql on the old box to the new was the cure.

…are the shortcuts.

I’ve been using control-shift-t extensively since Darius first showed it to me a few months ago.  It will let you quickly find and jump to a java class across your current workspace.  (There is also an Open Type button by default in eclipse that you can use.)

I’ve always wanted a way to do the same except with our jsp, xml, and properties files.  I know most of the names of files and know where they are, I’m just lazy.  I want to be able to jump to them without having to expand the whole tree.

Well, Open Resource to the rescue!  Control-shift-r works just like the Open Type except with nonjava files.  Woot!

Yesterday I was lamenting the fact that Eclipse doesn’t have a middle-click-closes-tab functionality as Firefox does.  It finally disturbed me enough to go and do a quick google search for it.  Lo and behold, out of those many other Eclipse-loving programmers out there, one of them felt as I did.

I now have the ability to close my tabs with a simple middle click thanks to Andriy Palamarchuk and the middle click closes tab plugin.
