> Key: SCM-679
> URL: https://jira.codehaus.org/browse/SCM-679
> Project: Maven SCM
> Issue Type: New Feature
> Components: maven-scm-api, maven-scm-provider-bazaar,
> maven-scm-provider-git, maven-scm-provider-mercurial (hg),
> maven-scm-provider-svn
> Affects Versions: 1.7, 1.8
> Reporter: Petr Kozelka
> Attachments: scm-changelog-limit.patch,
> scm-changelog-limit-wrapped.patch
>
>
> The current api returns changesets between specified/unspecified
> dates/revisions.
> This leaves some important usecases unsupported; some of them are:
> - get last changeset on given repository/path
> - get last n changesets there ("first page" when browsing changes)
> The only workarround currently possible is, list all commits and filter them
> - but this is very time consuming.
> For this reason, I propose attached enhancement which overloads the changeLog
> method, adding the limit parameter:
> {code}
> ChangeLogScmResult changeLog( ScmRepository repository, ScmFileSet
> fileSet, Date startDate, Date endDate,
> int numDays, ScmBranch branch, String
> datePattern, Integer limit )
> throws ScmException;
> {code}
> For the "last changeset" usecase, the client sets limit = 1.
> For "paged browsing", it can specify null startDate/endDate on firstPage, and
> then work with dates for next/previous pages, still using the limit to
> specify page size.
> Note that the limit parameter can be null (as it is "Integer", not "int") to
> specify unlimited number of returned changesets.
> The suggested patch includes deprecations of enhanced methods, I hope this is
> a good way to reduce the number of actively used overloaded variants of
> "changelog" in future.
