Description:

A simple database sourceCodeManager, which saves versions in a relational db

unfinished

Class protocol:

 getRepositoryDBForModule: aModuleName

internal: used when accessing a source repository.
Return the db-name for a particular module.
If no specific db was defined for that module, return the value of
the global (fallBack) repositoryDB.
Nil is returned if no repository is available.

 knownModules

return the modules, we currently know

 repositoryInfoPerModule

return the dictionary, which associates repository paths to module names.
If no entry is contained in this dictionary for some module,
the default path will be used.

 repositoryInfoPerModule: aDictionary

set the dictionary, which associates repository paths to module names.
If no entry is contained in this dictionary for some module,
the default path will be used.

 repositoryName

return the default repository

 repositoryName: aDBSpec

set the default repository

 utilities

Returns a 'utilities' object that can be used by tools.

 closeAllCachedConnections

 dbHandleForModule: aModuleName

 openDB: aDBName

 openODBC: dbSpec

 openSQLite: dbSpec

 checkInClassAndCollectManifestOf: aClass db: dbConnection

check in a class; write one record for the definition,
then one for each method.
Return a manifest, which lists each save chunk's key.

 insertChunk: chunkData key: key db: dbConnection

already there?

 keyForChunk: aString

chunks are keyed by their sha1 hash value.
This has the advantage, that:
- the key alone shows if anything has changed,
- no new record is required if a chunk is unchanged,
- going back to an old version automatically reuses/refers to the old chunk,
- two independently changed methods will generate the same key

 manifestOfStoredClassDefinitionOf: aClass db: dbConnection

save a class definition;
return a manifest line

 manifestOfStoredMethod: aMethod selector: aSymbol meta: isMeta db: dbConnection

save a method;
return a manifest line

 savePreferencesOn: aStream

 defaultRepositoryName

'<db-type>:[<user>[.<password>]@][<host>]<db-name>[:<table-name>]'

 enabled

false.

 getDBNameForModule: anString

for now, one repository for all modules

 initialRevisionString

 isContainerBased

true, if the SCM uses some kind of source container (,v files).
False, if it is like a database or filesystem.

 isResponsibleForPackage: aString

(comment from inherited method)
Returns true if the manager can handle source code for given package.

Answering true does not imply that receiver is configured default
manager for that package, it only means that it has a repository
configured for given package.

 managerTypeName

(comment from inherited method)
Answers version manager name suitable for UI,
i,e., CVS, SubVersion, Perforce

 nameOfVersionMethodForExtensions

(comment from inherited method)
that is the old name; now, we use extensionsVersion_<SCM>

 nameOfVersionMethodInClasses

(comment from inherited method)
that is the old name; now, we use version_<SCM>

 repositoryNameForPackage: packageId

superclass AbstractSourceCodeManager class says that I am responsible to implement this method

 settingsApplicationClass

link to my settings application (needed for the settings dialog

 versionInfoClass

 basicCheckinClass: aClass fileName: classFileName directory: packageDir module: moduleDir logMessage: logMessage force: force

low level checkin of a class into the source repository.
Does not deal with any version method updates.
Return true if ok, false if not.

 checkForExistingContainer: fileName inModule: moduleName directory: packageDirName

check for a container to exist. Return a boolean result.

 checkForExistingModule: moduleDir

check for a package directory to be present

 checkForExistingModule: moduleDir directory: packageDir

check for a package directory to be present; return true, if it does

 checkinClass: aClass fileName: classFileName directory: packageDir module: moduleDir source: sourceFile logMessage: logMessage force: force

Return true if ok, false if not.

 createModule: moduleDir

create a module directory

 createModule: moduleDir directory: packageDir

create a package directory

 initialRevisionStringFor: aClass inModule: moduleDir directory: packageDir container: fileName

return a string usable as initial revision string

 revisionInfoFromString: aString

return a VersionInfo object filled with revision info.
This extracts the relevant info from aString.

usage example(s):

self revisionInfoFromString:'Path: stx/libbasic/Array.st, Version: 123, User: cg, Time: 2011-12-21T21:03:08.826 SymbolicVersion: foo'

 revisionLogOf: clsOrNil fromRevision: rev1OrNil toRevision: rev2OrNil numberOfRevisions: limitOrNil fileName: classFileName directory: packageDir module: moduleDir

|info log targetDir count newestRevision|

 streamForClass: aClass fileName: classFileName revision: revision directory: packageDir module: moduleDir cache: doCache

|targetDir oldFile|

 updateVersionMethodOf: aClass for: newRevisionString

helper for the checkin procedure.
Update my #version_XXX method, to now return newRevisionString.
