Subject: [gentoo-portage-dev] idea for portage: cascading
Date: Mon, 09 Feb 2004 09:37:49
1 Hi all,
3 looking around for a pkg-mgmt-tool for our source-packages, which
4 works on unix-like platforms such as HP-UX,AIX,SunOS,Linux and Cygwin,
5 i've not been very lucky yet.
7 So i startet to write a new one using top-level GNU-Makefiles,
8 just for our requirements, intended to be used until another,
9 more professional one, becomes useful for us.
11 One feature i want to implement soon is "cascading" (i'd call it so),
12 and i think this idea might be useful for portage, and would help
13 portage to get useful for us (yet missing platform indepency).
15 Assume you've one top-level installation of the system, which might
16 be basically managed by the system-imposed pkg-manager (rpm, deb,
17 portage, whatever on HP-UX/AIX/Sun/Cygwin).
19 On top of this, on non-portage-managed systems there's one installation
20 of portage with all of the system-level packages (libc, compiler, perl,
21 python, ...) injected (i think this is what portage calls injection).
23 Then, in some subdirectory (might be versioned), there would be another
24 portage installation, where one package with another version (or SLOT?)
25 is compiled, and all the depending packages are recompiled, while the
26 independants would be inherited from the top-level installation.
27 Let this installation be for all the developers of one project,
28 which requires a special version of one package.
30 Additionally, there's a third installation, again with another version
31 (or SLOT?) from another package, and all the dependants are compiled
32 again, while the independants are inherited.
33 For instance, this installation would be for one developer, who does
34 integration-test a new version of this package.
36 Hoping not to waste your time,
37 Michael
