Validation of the SQLite folder indices merge into kdepim trunk (805075).

Notes

• "OK" means files or methods inspected in every detail.
• We do not mention changes that only add/remove kDebug(), etc.

Results

• compactionjob.cpp - OK
  • void MboxCompactionJob::done( int rc ): the only addition: result of KDE_rename() is checked, return immediately on failure

• folderstorage.cpp, folderstorage.h
  • QString FolderStorage::indexLocation() const - implemented here to return "*.index" name for mmap mode ("*.index.db" for sqlite mode). Previously it was abstract and implemented in KMFolderIndex. KMFolderSearch reimplements it to return "*.index.search" name - see kmfoldersearch.cpp for details.
  • added virtual QString FolderStorage::location(const QString& suffix) const helper, used in various *location() methods of in KMail, to avoid code duplication; returns full path to .index, .index.ids or .index.sorted file (depending on suffix); the former path (in case of mmap-based implementation) is returned when the suffix is empty.
  • QString FolderStorage::sortedLocation() const - added to avoid constructing paths using indexLocation() + ".sorted"

code

• • QString FolderStorage::idsLocation() const - added to avoid constructing paths using indexLocation() + ".ids"

code

• kmailicalifaceimpl.cpp - OK

void KMailICalIfaceImpl::readConfig() - added sanity check: if ( !mCalendar || !mTasks || !mJournals || !mContacts || !mNotes )

 return;

KMFolder* KMailICalIfaceImpl::initFolder( KMail::FolderContentsType contentsType ) - added check for result of open():if ( 0 != folder->open( "ifacefolder" ) ) { ....

• kmfolder.cpp, kmfolder.h
  • QString KMFolder::indexLocation() const - made virtual but implementation is unaffected.
  • QString KMFolder::sortedLocation() const - calls FolderStorage::idsLocation() if storage is presents, else returns empty string; added as a helper for KMHeaders so we don't need to call mFolder->indexLocation() + ".sorted"; gives effectively the same result - OK
  • QString KMFolder::idsLocation() const - like above but for ".ids" names - OK

• kmfolderdir.cpp - OK
  • bool KMFolderDir::reload(void): no changes, as .index.db files are only ignored for sqlite mode - OK

• kmfolderindex.cpp, kmfolderindex.h

• kmfoldermaildir.cpp

• kmfoldermbox.cpp

• kmfoldersearch.cpp - OK
  • QString KMFolderSearch::indexLocation() const now just calls FolderStorage::location( "search" ) utility function what has the same effect
  • int KMFolderSearch::writeIndex( bool ): at the very end final, result of KDE_rename() from temp name to the indexLocation() name is checked; on faulure the method fails, what cause that "mDirty = false; mUnlinked = false;" code is not executed. - OK

• kmheaders.cpp, kmheaders.h - OK
  • #define KMAIL_SORT_FILE(x) x->indexLocation() + ".sorted" replaced by #define KMAIL_SORT_FILE(x) x->sortedLocation() - uses a new utility FolderStorage::sortedLocation() method having basically the same source code - OK
  • void KMHeaders::setNestedOverride( bool override ) - like above - OK
  • void KMHeaders::setSubjectThreading( bool aSubjThreading ) - like above - OK
  • void KMHeaders::writeFolderConfig (void): minor optimization: mFolder->getMsgBase( current->msgId() ) is called once instead of twice - OK
  • bool KMHeaders::writeSortOrder() - the only addition: result of KDE_rename() is checked, return immediately on failure
  • QList< Q_UINT32 > KMHeaders::selectedSernums() - sanity check added in case when KMMsgBase *msgBase = mFolder->getMsgBase( item->msgId() ); returns null result; this shouldn't happen - OK
  • QList< Q_UINT32 > KMHeaders::selectedVisibleSernums() - like above

• kmkernel.cpp - OK
  • void KMKernel::slotRunBackgroundTasks(): added sanity checks for null pointers: the_folderMgr, the_imapFolderMgr, the_dimapFolderMgr; this is neutral change

• kmmsgbase.cpp
• kmmsgbase.h

• kmmsgdict.cpp - OK
  • QString KMMsgDict::getFolderIdsLocation( const FolderStorage &storage ): the new FolderStorage::idsLocation() is called which provides the same code as the original impl. of KMMsgDict::getFolderIdsLocation(). - OK

• kmmsginfo.cpp
• kmmsginfo.h

• messageproperty.cpp - OK
  • minor optimizations only added, for example 1. instead of 2.:
    1. QMap<quint32, QPointer<KMFolder> >::ConstIterator it = sFolders.constFind( serNum );
       return it == sFolders.constEnd() ? 0 : (*it).operator->();
    2. if (sFolders.contains(serNum))
         return sFolders[serNum].operator->();
       return 0;
  • Affected methods:
    • KMFolder* MessageProperty::filterFolder( quint32 serNum ) - Status: OK
    • ActionScheduler* MessageProperty::filterHandler( quint32 serNum ) - Status: OK
    • bool MessageProperty::transferInProgress( quint32 serNum ) - Status: OK
    • void MessageProperty::setTransferInProgress( quint32 serNum, bool transfer, bool force ) - Status: OK
    • quint32 MessageProperty::serialCache( const KMMsgBase *msgBase ) - Status: OK
