JiraIssueChangeHistory

Added by Tom Chiverton, last edited by Tom Chiverton on Jun 22, 2005

Once you have a Jira issue, you can obtain it's change log, for instance to find it's resolved date.

A given change entry has a map, much like JiraIssueProperties:

 
[GenericEntity:ChangeItem][oldvalue,null][group,11438][newvalue,null]
[field,Assignee][oldstring,tchiverton][newstring,rfry][id,12159]
[fieldtype,jira]

and a datestamp, .getTimePerformed().

Each instance of a change entry may have a different value for field, such as status, and a corresponding set of newvalues, such as 'Resolved'.

You can obtain the changes for an issue thus:

 
private Date findResolvedDate(GenericValue issue,User remoteUser) throws GenericEntityException {
        DefaultActionManager am = new DefaultActionManager();
        List changes = am.getChangeHistory(issue,remoteUser);

        Iterator it = changes.iterator();
        while (it.hasNext()) {
            ChangeHistory change = (ChangeHistory) it.next();
            List chng = change.getChangeItems();
            Date chgTime = change.getTimePerformed();
            // -- get last status change - it is the most recent  ---
            for (int i = chng.size()-1 ; i>=0 ; i--) {
                GenericEntity chgItem = (GenericEntity) chng.get(i);
//log.debug(" change items ="+chgItem +", date="+chgTime);
                if (chgItem.getString("field").equalsIgnoreCase("status") &&
                    chgItem.getString("newstring").equalsIgnoreCase("resolved")
                ) {
log.debug(" resolved @"+chgTime);
                    return chgTime;
                }
            }
        }

    Please note that if you want to find the last change date, you need to iterate over the changes. (This was a mistake in the original code that I shared earlier. Here is a snippet to find the date stamp for the last status change:

    lastStatusChange = issue.getTimestamp("created");
    try

    Unknown macro: { changes = am.getChangeHistory(issue,user); }
    catch (GenericEntityException e)
    Unknown macro: { //throw new DataAccessException(e); changes = null; }

    if (changes!=null) {
    // – get last status change - it is the most recent —
    getlastchange: for (int k = changes.size()1; k>=0; k-) {
    ChangeHistory change = (ChangeHistory) changes.get(k);
    List chng = change.getChangeItems();
    Date chgTime = change.getTimePerformed();

    for (int i = 0 ; i<chng.size() ; i++) {
    GenericEntity chgItem = (GenericEntity) chng.get;
    if (chgItem.getString("field").equalsIgnoreCase("status"))

    Unknown macro: { lastStatusChange = chgTime; break getlastchange; }

    }
    }
    }
