= python-launchpad-bugs Examples =

This page contains two examples on how using python-launchpad-bugs.

== parse changelog and close upstream bugreports ==

This script parses 'debian/changelog' for statements like '(LP: #123456)' and closes upstream bugreports.

{{{#!python
import launchpadbugs.connector as Connector
import re

Bug = Connector.ConnectBug()
Bug.authentication = "/home/markus/.gnome2/epiphany/mozilla/epiphany/cookies.txt"
LP_BUGS = re.compile("\(LP: ?#?(?P<bug>[0-9]+)\)")

class Entry(object):
    def __init__(self, text):
        self.text = text
        
    def closed_bugs(self):
        return map(int, LP_BUGS.findall(self.text))
        
        

class ChangeLog(list):
    def __init__(self, filename):
        changelog = file(filename, "r")
        L = []
        for i in changelog.readlines():
            if i.startswith(" -- ") or i.startswith("-- "):
                tmp += i
                L.append(Entry(tmp.strip("\n")))
            elif i.strip("\n") and not i.startswith(" "):
                tmp = i
            else:
                tmp += i
        list.__init__(self, L)
        

#c = ChangeLog("/home/devel/bughelper/main/debian/changelog")
c = ChangeLog("debian/changelog")
for i in c[:1]: #this only checks the last entry, but it's easy to define a range (cmd-line option?)
    comment = Bug.NewComment(text=i.text,subject="auto closed by script")
    for b in i.closed_bugs():
        bug = Bug(b)
        print "checking", b
        if not bug.status == "Fix Released":
            print "changing", b.url
            b.comments.add(comment)
            b.status = "Fix Released"
            b.commit()
}}}

== Search buglists by content of an attachment ==

This is an example on how to filtering buglists by the content of an attachment

{{{#!python
import launchpadbugs.connector as Connector
from launchpadbugs.basebuglistfilter import URLBugListFilter, StopFiltering
from launchpadbugs.bugbase import Bug as BugBase
import datetime

Bug = Connector.ConnectBug("text")
BugList = Connector.ConnectBugList()

def reported_since(b):
    if not isinstance(b, BugBase):
        b = Bug(b)
    if not False in map(lambda x: x.date_created < datetime.datetime(2008,02,18), b.infotable):
        raise StopFiltering
    if "pycentral" in b.text or "python-central" in b.text:
        return b
    for a in b.attachments:
        if a.description == "DpkgTerminalLog.gz":
            if "pycentral" in a.text or "python-central" in a.text:
                return b
    return False

bug_filter = URLBugListFilter()

bug_filter.functions.append(reported_since)    

bl = BugList(bug_filter(url))
for b in bl:
    print b.url
    print "\t", b.duplicates, b.duplicate_of
}}}

== mass closing of bugs ==

{{{#!python
from launchpadbugs.connector import ConnectBug, ConnectBugList

cookie = "/home/markus/.mozilla/firefox/iy3ore6m.default/cookies.sqlite"
Bug = ConnectBug()
Bug.authentication = cookie
Buglist = ConnectBugList()
Buglist.authentication = cookie

bl = Buglist("https://bugs.edge.launchpad.net/~thekorn")
print len(bl)

count = 0

for i in bl:
    com = Bug.NewComment("mass closing of old buglog-data bugs", "closing this old buglog-data bug")
    if i.sourcepackage == "buglog-data":
        count += 1
        b = Bug(i)
        b.status = "Invalid"
        b.comments.add(com)
