Current Work and Plans• Need to figure out how to implement default sam configuration offsite

• Testing 6.1.6.md

• New root rebuilt, failed: DROP SL4 support for 6.1.6.md?

• Compile SL4 Link SL5?

• New version of 6.1.6.md this afternoon

• 5.28.0.d should be ready in kits soon

• Need new diskcache_i for new root

• Test 6.1.6.md quickly and replace 6.1.6.ml (only in use in 3 places)

• Combine 6.1.4mc.m and patches into 6.2.6alpha: list almost ready

• Combine 6.1.4mc.m and patches into 6.2.4alpha

• Test 6.2.6alpha and 6.2.4alpha against gcc 4.5.1

Wish Lists

6.1.6.ml and 6.1.4mc.m

• Error in earlier comparisons: Did not include 6.1.6 patches and some 6.1.4mc patches included roll-backs

• Some experts weighed in, others did not

Wish Lists

Wish Lists

• Tools• Support• Code• Products

Tools Wish List

• Code Browser to handle non-CDF code– Is this important enough to commit time to?

• Expanded validation suite– Not worth effort if there’s only a single release

pair pending

11 May 2011 7

Support Wish List

• RHEL6– Compiler is available. When 6.2.6 preliminary is

ready, shake down code

• Code librarians– Still at 2/3 of total, and falling

• Better organized documentation– Ongoing: Need to find a way of searching it all

11 May 2011 8

Code Wish List

• Uninitialized variables– Full search is big job– Tesarek fixed a lot of type casting problems

• Program speedup– No great luck so far• 1st try failed validation and wasn’t much faster

11 May 2011 9

Product Wish List• New root for 6.2.X

– Yes

• Merge 6.1.4mc and 6.1.6– 6.2.6

• New MC engines– 6.2.4

• CafUtil– A month? When will work start on this?

• Package Pruning– See below—not much excess

• Product executable built 64-bit– Not clear this buys us anything

• Product recompiling on SL5– See later slide: want to get rid of shared libraries

• Oracle 11– Test soon—who?

• Reduce number of error messages– Serious push-back on this—it undermines diagnostics

• Use of xrootd– No news—need to create a testbed: Which versions, and what is security going to do to connections?
