File cvs2fossil.txt part of check-in [f637d42206] - Updated my notes regarding memory usage. Converted more locations to incremental query processing via 'state foreachrow', now throughout the importer. by aku on 2008-02-24 18:01:40.

Known problems and areas to work on
===================================

*	Not yet able to handle the specification of multiple projects
	for one CVS repository. I.e. I can, for example, import all of
	tcllib, or a single subproject of tcllib, like tklib, but not
	multiple sub-projects in one go.

*	Consider to rework the breaker- and sort-passes so that they
        do not need all changesets as objects in memory.

	Current memory consumption after all changesets are loaded:

	bwidget		 6971627    6.6
	cvs-memchan	 4634049    4.4
	cvs-sqlite	45674501   43.6
	cvs-trf		 8781289    8.4
	faqs		 2835116    2.7
	libtommath	 4405066    4.2
	mclistbox	 3350190    3.2 
	newclock	 5020460    4.8
	oocore		 4064574    3.9
	sampleextension	 4729932    4.5
	tclapps		 8482135    8.1
	tclbench	 4116887    3.9
	tcl_bignum	 2545192    2.4
	tclconfig	 4105042    3.9
	tcllib		31707688   30.2
	tcltutorial	 3512048    3.3
	tcl	       109926382  104.8
	thread		 8953139    8.5
	tklib		13935220   13.3
	tk		66149870   63.1
	widget		 2625609    2.5

*	Look at the dependencies on external packages and consider
	which of them can be moved into the importer, either as a
	simple utility command, or wholesale.

	struct::list
		assign, map, reverse, filter

		Very few and self-contained commands.

	struct::set
		size, empty, contains, add, include, exclude,
		intersect, subsetof

		Most of the core commands.

	fileutil
		cat, appendToFile, writeFile,
		tempfile, stripPath, test

	fileutil::traverse
		In toto

	struct::graph
		In toto

	snit
		In toto

	sqlite3
		In toto
