They are difficult for users to install, and very difficult for me to maintain, doing 'partial' patching, fixing and re-diffing trying to get collisions removed as much as possible. There is also a pretty heavy inherent order which most of these patches have to be installed, before other patches work. The patches I am working with and referring to, are: MinGW-VC This one 'should' not depend on other patches, but may collide. I am working on removing all collisions with my other patches. fast-MD5 The changes I did merging the SSE2 and the 'fast' x86 methods. phpass depends upon fast-md5 performance-enhancements depends upon phpass (and thus fast-md5) Several-new-runtime-options Depends upon performance patch generic-md5 Depends upon at least one of the 'new' options, but adds several other new options. This one collides heavily with the 'options' update **** My first question to users (To Solar in specific). Should I wind up all of these into a 'single' patch? (well 2 patches, as the MinGW patch will not be part of the larger one) **** Yes, the user 'loses' the ability to select which part they want, and end up with all. However, the patch should be easy to build to install directly to 18.104.22.168-jumbo-X level (jumbo-1 at this time). It will be easy to get it PROPERLY patched in by the end user. That is one of the problems right now. It will also be much easier for me to maintain, and to make sure I get the proper items included into the patch. If this is not poo-poo'd by the group, that is the plan I will be moving forward with. I will NOT put the MinGW/VC build patch into the other 'main' patch, so there will end up being 2 patches. The MinGW-VC will be made to work straight from the jumbo-1 or made to work correctly after the other large patch (generic-md5-performance-options I think is what I will 'call it') patch. That generic-md5-performance-options patch will also be done so that it works perfectly from 22.214.171.124-jumbo-1 or from 126.96.36.199-jumbo-1 + MinGW-VC (i.e. both patches work in any order, and properly patch). I have several reasons for this query. One, I want to move things so that the properly link into the current stable 188.8.131.52 + jumbo-1 level. Second, I have some significant changes in the md5-generic modules. Performance gains, and also getting benchmarking working very good, and having to make changes to HOW benchmark code works (since there are now 17 generic md5's, so there is one format that tests 17 times). So this required some changes to how bench does it's work. Third, there are several 'built-in' formats which can be trimmed down to VERY minimal, and then simply 'hook' into the md5-gen code. The ones I have already done are: md5-raw phpass PHPS and I am sure there are others. But to get to the stage where I can 'release' these, I have to get to a point where the md5-gen is properly released. Thus the 'spider-web' of patch collisions and dependencies, which I would like to alleviate by combining the patches into a larger 'super' patch. Jim.
