Hi All,
I've not started coding this yet as I'm still getting the environment
setup, but here is the rough outline (pseudo code) of the overall flow
for this. A few things of note:
Must of the mantis stuff relies on info from the web database thus
'add' operations should be web then mantis while 'delete' operations
should be mantis then web.
I'm envisioning a code pattern that allows for listener plugins. A
general call to remove_pkgs(pkgset) would be called. That would then
iterate over the listeners that are plugged in calling their remove
methods. I'll register a mantis listener and a web db listener.
Listeners will have priorities to facilitate ordering although I'm not
sure the best way (yet) to handle this.
This design should allow swapping out mantis code for $new_bugtracker
later without too much work.
Detecting renames is important in the _stub case. I'll likely need to
catch it in the general case too. Things would have been _much_
simpler if the package name instead of the software name was set as
the key for everything...
Anyway, pseudo code. Any obvious issues?
oldcat = load_old_catalog()
newcat = fetch_new_catalog()
[new, update, remove] = new_compared_to_old(oldcat, newcat)
stubs = find_stubs(new, update)
renames = []
for p in stubs
# determine based on package name what the old software name was
# (this does not rely on stub naming convention of $oldname ->
# $oldname + '_stub') as we'll actually look it up
stub_oldname = lookup_softname_by_pkgname(p)
# scan all packages about to be dropped
for q in remove
# if a dropped package software name is the stub's old name,
# handle a renaming case.
if q.softname = stub_oldname
# save the rename pair
renames << [p, q]
# no longer treat this package as a pure removal
remove = remove - q
# no longer treat the stub as a pure add or update
new = new - p
update = update -p
for [p,q] in renames
rename_pkg_in_mantis(p, q)
rename_pkg_in_webdb(p, q)
for p in remove
remove_pkg_from_mantis(p)
remove_pkg_from_webdb(p)
for p in new
add_pkg_to_webdb(p)
add_pkg_to_mantis(p)
for p in update
update_pkg_in_mantis(p)
update_pkg_in_webdb(p)
function rename_pkg_in_webdb(p, q)
# rough sql idea
update packages set pkgname = p.pkgname, maintainer =
p.maintainer, ... where q.softname = packages.softname
function rename_pkg_in_mantis(p, q)
# rough sql idea
update mantis_project_table ...
function delete_pkg_in_webdb(p)
delete from packages()
delete from dependencies () ...
delete from dependlibs () ...
delete from pathnames () ...
delete from uniquepaths () ...
function delete_pkg_in_mantis(p)
delete from mantis_project_user_table () ...
delete from mantis_project_table () ...
function add_pkg_to_webdb(p)
insert into packages ()...
insert into dependencies () ...

function add_pkg_to_mantis(p)
insert into mantis_project_table ()...
