Bug 74389 – [Refactoring] Remove several global variables from prepare-ChangeLog

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Kentaro Hara]

We are planning to write unit-tests for prepare-ChangeLog in a run-leaks_unittest manner. This bug is one of the incremental refactorings to remove all top-level code and global variables from prepare-ChangeLog.

Global variables in prepare-ChangeLog can be categorized as follows:

[A: Constant variables]
$changeLogTimeZone
$SVN
$GIT
%supportedTestExtensions

[B: Arguments]
$bugDescription
$bugNumber
$name
$emailAddress
$mergeBase
$gitCommit
$gitIndex
$gitReviewer
$openChangeLogs
$writeChangeLogs
$showHelp
$spewDiff
$updateChangeLogs
$parseOptionsResult

[C: Global variables that are used many times here and there]
$isSVN
$isGit

[D: Global variables that are used only a few times]
%paths
$changedFiles
$conflictFiles
$functionLists
$addedRegressionTests
$bugURL
$filesInChangeLog
$prefixes
$changeLogs


In this bug, we remove all global variables in [D]. More accurately, we make all variables in [D] being used only through parameter passing.

> +my ($changedFiles, $conflictFiles, $functionLists, $addedRegressionTests) = generateFileList(%paths);

In the future, it seems like we should try to come up with a data structure to hold this data instead of passing a list of variables back.

This is okay for now, though.
