From: Kevin Lewis Date: February 4 2009 10:39pm Subject: January Bug Report for Falcon List-Archive: http://lists.mysql.com/falcon/491 Message-Id: <498A192C.3070601@sun.com> MIME-Version: 1.0 Content-Type: text/plain; format=flowed; charset=ISO-8859-1 Content-Transfer-Encoding: 7BIT The Falcon Team verified 57 bugs in January and fixed or otherwise reclassified 50 bugs. See https://inside.mysql.com/wiki/FalconBugfixPlan Commentary for January, 2009 * Good News - This was the most productive month ever by Falcon engineers (if we limit the definition of productivity to bug counts, which is pure tunnel vision). Nevertheless, 39 Bugs were fixed and another 11 were reclassified as Can't Repeat, Duplicate, Closed or NotABug. Kevin fixed 15 bugs, many of which were related to the improvements to the Scavenger that he pushed this month. Vlad fixed 10 Bugs, 5 of them were related to recovery. Chris fixed 7 bugs in a variety of areas. * Bad news - Unfortunately, this month also had the most bugs ever verified against Falcon. 77% of these (44 of 57) were reported by Falcon team members. 26% (15 of 57) were opened by Falcon engineers as they dug deeper into the code. Philip opened a record 19 bugs against Falcon this month as he put the Random Query Generator into overdrive. He made a number of enhancements to it as he tried out more and more combinations of query and reporting types. * Many new bugs were exposed by the new scavenger in combination with the new transaction dependency management code. A couple of them were mistakes in the scavenger code, but a large number were existing concurrency bugs that were exposed by the more frequent scavenger activity. Exact numbers are not known. * The active bug count went up by 7 but the BETA Bug count went down by 4. The beta bug count was made at 12:01 on February 1 and many verified bugs were not triaged at that time. In hindsight, waiting a week for the triage process to take place, the BETA bug count probably would went up in January. * Of the 57 new bugs reported, 13(23%) were reported by folks outside the Falcon group. Verified bugs were reported by; Philip=19, Olav=5, John=5, Hakan=4, Vlad=4, Kevin=3, Nidhi=3, Callaghan=2, Ranger=2, PeterG=1, Chris=1, Dmitri=1, Kelly=1, Lars-Erik=1, Mattias=1, Petrunia=1, Shane=1, Sveta=1, Svoj=1 * At least 66% (38 out of 57) of bugs verified in January were triaged as Beta bugs. 4 verified bugs are still not triaged. This high percentage will keep us from reaching Beta in the next several months.
