Hey. is a dependency checking time of 1.5 seconds for 189 packages fast? ^_^ and it can be ALOT faster aswell. Page Parsed in: 1.5912721157074 seconds. (mostly php) MySQL Parsed in: 0.0009613037109375 seconds. (MySQL only) php is doing the recursive functions and a in_array thing (in a few arrays with a few 100 entry`s) so the php part can be improved for speed improvements, but the best thing would be to write this thing in c/c++. the mysql parsetime of all the dependency`s recursively in php is JUST 0.001 (rounded up) so the total time for all this stuff could very well be under one second. I did the dependency check on KDEBASE, but the test isn`t really 100% fair. like i don`t have the currently installed packages striped out against the ones that my dependency checker says are needed for KDEBASE. but this is because i have very limited access to the rpm database with php. so if i would have done this based on my current system (with the installed packages) it would probably be a little higher parsetime for mysql because it would need to check every package if it`s already installed on my system and if it is it will also need to check the version and release numbers.. so a fair estimate of the parsetime in that case would probably be 0.003 MAX (still extremely fast) Now why did i open up this thread? and why in the fedora-devel-list? well i think this stuff concerns fedora and it`s (my dep checker) in development so that`s why i posted it here. i`m actually making this with the idea of removing yum completely (also pup, pirut and puplet but those are still idea`s.. for that i need to learn alot more c/c++ (no i don`t want to write those gui apps in python or even in php) The reason i posted it here is because i`m hoping to attract the attention of a programmer who is willing to help me out in making this app a c/c++ app so that it really CAN be used in fedora. or if someone could enhance the php_rpm extension so that i can also check it against the currently installed rpm`s instead of only playing with rpm files. or a way of reading out the rpmdb. (i need to know the installed: Names, Version and Releases). And why did i make it? quite simple. i simply don`t believe that installing a package really has to take SO MUCH time (with checking the dependency`s) so i started making my own dependency checker. this stuff is the result of a one day php work. 2 php classes and done. the total thing is probably about 22 kilobytes!! (with lots of useless stuff in it aswell). Originally i had the idea to make a online dependency checker so that rpm maintainers could upload there rpm file in the dependency checker which would check if there aren`t and conflicting things in the header to install it.. soon after that i realized that the original idea was fine but that so much more could be done with this.. so adding a few nore lines changed the way the scrpt was working to be a dependency checker only. My initial version did the kdebase dependency`s in about 30 seconds. that was on tables without any indexes, this one does it in 0.001 secounds and than the tables still aren`t 100% optimal. there are still alot of doubles in it and it isn`t splitted alphabetically (so all the A deps in a deps_a table and so on for: 0-9 a-z. and at this moment all the rpm files that come with fedora core 7 test 3 are indexed. my way of checking dependency`s has a few advantages and disadvantages. (alot more advantages.. but i name just 3 of both) Advantages: - Alot faster than any rpm installation tool - Way smaller "repodata" files (under 1MB) - Alot less waiting on the dependency`s Disadvantages - A new "createrepo" program will need to be written - Existing repository`s won`t work (perhaps will with a yet to make repo converter which converts the sqlite or xml data to the style + format i want) - could devide the rpm based distributions (into distributions that use yum and distributions that use my program) but serious.. is this a world record? (i even think it`s faster than ubuntu and all other systems that are currently existing) i hope to see some reply`s on this post.
