## Constructor & Destructor Documentation

## ◆ Impl()

zypp::PurgeKernels::Impl::Impl | ( |  | ) |
| inline

Definition at line 61 of file PurgeKernels.cc.

## Member Function Documentation

## ◆ setUnameR()

void zypp::PurgeKernels::Impl::setUnameR | ( | const std::string & | uname | ) |
| inline

Definition at line 82 of file PurgeKernels.cc.

## ◆ removePackageAndCheck()

bool zypp::PurgeKernels::Impl::removePackageAndCheck | ( | const sat::Solvable | slv,
|  | const std::set< sat::Solvable > & | keepList,
|  | const std::set< sat::Solvable > & | removeList ) const

tries to remove a the PoolItem pi from the pool, solves and checks if no unexpected packages are removed due to the validRemovals regex. If the constraint fails the changes are reverted and false is returned.

Definition at line 144 of file PurgeKernels.cc.

## ◆ versionMatch()

bool zypp::PurgeKernels::Impl::versionMatch | ( | const Edition & | a,
|  | const Edition & | b )
| static

Return true if a == b or a == (b minus rebuild counter)

Definition at line 278 of file PurgeKernels.cc.

## ◆ parseKeepSpec()

void zypp::PurgeKernels::Impl::parseKeepSpec | ( |  | ) |

Parse the config line keep spec that tells us which kernels should be kept

Definition at line 300 of file PurgeKernels.cc.

## ◆ fillKeepList()

void zypp::PurgeKernels::Impl::fillKeepList | ( | const GroupMap & | installedKernels,
|  | std::set< sat::Solvable > & | keepList,
|  | std::set< sat::Solvable > & | removeList ) const

Go over the list of available Editions for each flavour/arch combinations, apply the keep spec and mark the packages that belong to a matching category as to keep

All packages with Arch_noarch will only be matched against the version but NOT the flavour, reasoning for that is simply that source flavours not necessarily match the binary flavours. Without a translation table that would not be doable. This is also what the perl script did.

## ◆ _uname_r

std::string zypp::PurgeKernels::Impl::_uname_r

Definition at line 126 of file PurgeKernels.cc.

## ◆ _runningKernelEditionVariants

std::set<Edition> zypp::PurgeKernels::Impl::_runningKernelEditionVariants

A kernel uname can expand into multiple variants especially with rc kernels, older rc releases replaced the upstream tag -rc with .rc, however newer code replaces it with ~rc. We need to check against all variants to match the correct one.
