| 27 | The libABC test

|
|---|
| 29 | (Case Studies - Case 2)
|
|---|
| 30 |
|
|---|
| 31 | The issue is, a package named `A` requires package `BCD` explicitly, and
|
|---|
| 32 | RPM detects implicit dependencies between `A` and `libB`, `libC`, and `libD`.
|
|---|
| 33 | Package `BCD` provides `libB`, `libC`, and `libD`, but additionally there
|
|---|
| 34 | is a package `B` providing `libB`, a package `C` providing `libC`, and
|
|---|
| 35 | a package `D` providing `libD`.
|
|---|
| 36 |
|
|---|
| 37 | In other words, there's a package `A` which requires four different symbols,
|
|---|
| 38 | and one of these symbols is provided by a single package `BCD`, which happens
|
|---|
| 39 | to provide all symbols needed by `A`. There are also packages `B`, `C`, and `D`,
|
|---|
| 40 | that provide some of the symbols required by `A`, but can't satisfy all
|
|---|
| 41 | dependencies without `BCD`.
|
|---|
| 42 |
|
|---|
| 43 | The expected behavior for an operation asking to install `A` is obviously
|
|---|
| 44 | selecting `BCD` to satisfy `A`'s dependencies
|
|---|
| 45 |
|
|---|
| 46 | This fails in yum because, yum selects the packages with the shortest name
|
|---|
| 47 | if multiple packages provides the same requirements
