Yes, it has some merits, but still how about the following events (in chronological order): 1. User installs package foo-1.0 which requres shared library from another package bar-1.0; 2. For some reason package foo-1.0 has been modified and its PKGREVISION number has been increased to 1; 3. Package bar-1.0 has been updated to new version 2.0 and version number of shared library from this package had been bumped. To indicate that PKGREVISION of port foo-1.0 has been increased to 2, as you suggest; 4. For some reason package building cluster fails to build new package foo-1.0_2 (for example due to some incompatible API changes in the shared library from the new bar-2.0 package); 5. The user checks for updates for his packages and sees foo-1.0_1 and bar-2.0. According to your logic, he concludes that that package foo-1.0_1 is the package that linked against bar-2.0, but this is WRONG, in fact he just missed previous update of the foo package. Therefore, as you can see, PORTREVISION bump is in fact rather weak indicator of "I am a package that has been linked with that newer version of the other package with the library bump etc". -Maxim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
