Merge lp:~jeff-apple/openvista-gtm-integration/bug327480 into lp:openvista-gtm-integration

[jeff.apple]

[jeff.apple (jeff-apple)]

This set of changes doesn't break the compile.

[Jon Tai (jontai)]

Jeff, your new approach seems to work, but instead of merging directly with mainline, I'd like to merge it with my gtm-packaging branch, then merge that branch into mainline. My branch has the infrastructure necessary to build GT.M RPMs that include your work.

I've already merged your branch into my gtm-packaging branch and re-created the diff for the RPMs and tested lightly. Everything seems to jive - great work! I'm going to Disapprove this merge request and put up one of my own in a few minutes.

+ * for a given <strptr, strlen, patptr, depth> tuple, we store the evaluation result.
+ * in the above,
+ *	<strptr, strlen>	uniquely identifies a substring of the input string.
+ *	<patptr>		identifies the pattern atom that we are matching with
+ *	<depth>			identifies the recursion depth of do_patalt() for this pattern atom ("repcnt" in code)
+ * note that <depth> is a necessity in the above because the same alternation pattern atom can have different
+ *	match or not-match status for the same input string depending on the repetition count usage of the pattern atom
+ * after a series of thoughts on an efficient structure for storing pattern evaluation, finally arrived at a simple
+ *	array of structures wherein for a given length (strlen) we have a fixed number of structures available.
+ * we allocate an array of structures, say, 1024 structures.
+ * this is a simple 1-1 mapping, wherein
+ *	for length 0, the available structures are the first 32 structures of the array,
+ *	for length 1, the available structures are the second 32 structures of the array.
+ *	...
+ *	for length 47, the available structures are the 47th 32 structures of the array.
+ *	for length 48 and above, the available structures are all the remaining structures of the array.
+ * whenever any new entry needs to be cached and there is no room among the available structures, we preempt the
+ *	most unfrequently used cache entry (to do this we do keep a count of every entry's frequency of usage)
+ * the assumption is that substrings of length > 48 (an arbitrary reasonable small number) won't be used
+ *	so frequently so that they have lesser entries to fight for among themselves than lower values of length.
+ * with the above caching in place, the program segment below took 15 seconds.
+ * it was found that if the array size is increased to 16384 (as opposed to 1024 as above) and the available
+ *	structures for each length increased proportionally (i.e. 16 times = 16*32 structures instead of 32 as above)
+ *	the performance improved to the extent of taking 3 seconds.
+ * but this raised an interesting question, that of "size" vs. "time" tradeoff.
+ * with increasing array size, we get better "time" performance due to better caching.
+ * but that has an overhead of increased "size" (memory) usage.
+ * to arrive at a compromise, a dynamic algorithm emerged. the process will allocate a small array
+ *	beginning at 1024 entries and grow to a max of 16384 entries as and when it deems the hit ratio is not good.
+ * the array only grows, i.e. there is no downsizing algorithm at play.
+ * the dynamic algorithm addresses to an extent both the "size" and "time" issues and finishes the below in 1 second.
+ * #defines for the dynamic algorithm growth can be found in patcode.h
