The next problem was exactly how faithfully you wanted to make the conversion. Unfortunately, the hg convert's version of cvsps is pretty basic and will fail on all but the simplest of repositories. Hence I had to switch, eventually, the the 2.2beta of cvsps proper. Also, use cvs admin in earnest once and you can kiss goodbye any chances of a faithful reproduction without manual fixes. In addition, the early version of cvs used in the anoncvs repository never handled files being introduced on a branch properly, so when you checkout against specific dates, you get unexpected results on the trunk :-( > A switch of the public CVS repository to Mercurial would be a major > improvement. > Agreed. My initial findings are also that mercurial is the preferred solution. It is not as powerful as git, or even as fast, but it is easier to work with and has better documentation. Besides, the speed differences were not that great (just google and you can get 100's of independent comparisons), and I would rather not trip over the rope. IMHO, nothing we do in eCos development warrants the use of git over that of mercurial (or bazaar). 90% of the features of git probably would not be used, even once you figured them out ;-) -- Alex Schuilenburg >>>> Visit us at ESC-Boston http://www.embedded.com/esc/boston <<<< >>>> Sep 22-23 on Stand 226 at Hynes Convention Center, Boston <<<< **** Visit us at ESC-UK http://www.embedded.co.uk **** **** Oct 7-8 on Stand 433 at FIVE ISC, Farnborough **** -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
