================================================================ Dear Bug Team! I've uncovered an issue that can be classified as "annoyance" (as opposed to places where assertions are failing and causing abnormal termination). I've been just starting to use aucTeX as opposed to vanilla LaTeX mode while writing my thesis, and I noticed that when the fonts are resized for section and subsection titles, under some circumstances when the resized text is at the top of the window (for example, when using mousewheel to scroll up and reaching a point where the font is resized at the top of the window, then trying to scroll down), scrolling down one line at a time, whether by the mouse wheel or by the "down arrow" button at the end of the scrollbar, will not work. This problem is then remedied by repositioning the view so that the resized text is not at the top of the window (for example, scrolling up if that is possible, or using the scrollbar). At first I thought that my mouse wheel wasn't working, as I had a section heading at the top of my window and it was preventing downscroll from working. For some additional information, my font for the buffer was defined in the cache as (("Lucida Console:Regular:10::Western" . [:family ("Lucida Console") :weight :regular :style 0 :size "10pt" :registry nil :encoding "Western"])) ============================================================ System Info to help track down your bug: --------------------------------------- uname -a: CYGWIN_NT-5.1 shinyworld 1.5.21(0.156/4/2) 2006-07-30 14:21 i686 Cygwin ./configure '--with-mule' '--with-package-path=/usr/local/share/xemacs/site-packages:/usr/share/xemacs/site-packages:/usr/share/xemacs/xemacs-packages:/usr/share/xemacs/mule-packages' '--with-site-lisp=yes' '--sysconfdir=/usr/share/xemacs-21.5-b27/etc' '--infodir=/usr/share/xemacs-21.5-b27/info' '--libdir=/usr/share/xemacs-21.5-b27/lib' '--with-modules' '--without-error-checking' '--mandir=/usr/share/man/man1' XEmacs 21.5-b27 "fiddleheads" (+CVS-20061011) configured for `i686-pc-cygwin'.

All discussion of SPREADFIRE on a conceptual level is confined to the previous two sections. Technical details and concerns of implmentation, however, are listed in detail below. \subsection{Query Plan Rewriting} \paragraph{} After CAPE's ordinary query plan creation method has executed, a second function is called to modify any SPREADFIRE operators in the plan to contain split and merge operators. This function, called doSpreadfirePlanMigration(), takes in the completed query plan and reconnects all of the SPREADFIRE operators to newly generated split and merge operators. Upon completion of this method, the query plan is ready to run in D-CAPE with SPREADFIRE extensions. \paragraph{} Internally, the SPREADFIRE migration method takes an iterative approach with respect to the operator tree. The merge operator, the new parent of each SPREADFIRE operator, is created and connected first. At this time, a check is also made to see if the merge operator needs to replace the replicated operator as a root of the query tree. After the merge operator is inserted, the split operators, children of the SPREADFIRE operator, are created and connected \emph{en masse}. Prior children of the replicated operator are connected as inputs of corresponding split operators, based on the input queue position of the parent. \begin{figure} \includegraphics{rewriting-graphic.eps} \caption{This graphic is a rough draft} \end{figure} \subsection{SPREADFIRE Operation} \subsection{The Grid Launcher} I wrote the grid launcher as a means to run experiments on the CCC computing grid cooperatively with other students. Some fun things about the grid launcher: \begin{itemize} \item \end{itemize} \subsection{``E\_NOTIMPL''} The abstraction of DCAPE's queueing system means that the merge operator is not inherently aware of which partition provides any given tuple. All input from the various partitions is pushed into a single input queue, which is read by the operator as a single input. This is acceptable for the experiment bed, as the relational union used for merging joins does not need to be aware of partitions. However, for aggregate functions there may be a need to process incoming data with a ``one from column A and one from column B'' approach. Extensions which take advantage of SPREADFIRE's inherent flexibility will need to implement an identification system for partition sources in the merge operator.
