| Summary | 0002458: namestore fails to terminate and instead goes into infinite loop at 100% CPU | ||||
| Description | The namestore went into an 'infinite' loop iterating over the (AFAIK entirely empty) database with increasingly insane offsets: (gdb) print *zi $4 = {next = 0x0, prev = 0x0, client = 0xbf9b80, has_zone = 1, zone = {bits = {969344875, 502515347, 1284176735, 585570901, 2275369411, 1828873488, 980617594, 2628203479}}, request_id = 0, offset = 932103, must_have_flags = 0, must_not_have_flags = 0} | ||||
| Steps To Reproduce | Just starting the current gnunet-setup, enabling GNS and flipping the database from sqlite to postgres, which causes gnunet-setup to re-start the gnunet-service-namestore (gnunet-setup also tries to iterate over the contents when this happens). | ||||

The same problem also arises with the existing testcases IF we switch the database from sqlite to postgres. So this seems to be a bit plugin-specific (which is odd as the plugins should behave the same way...). So might be a postgres-namestore-plugin bug as well. |
|
|
Fixed issue in postgres plugin in SVN 22283. Also had to actually make sure that the PG database was dropped on shutdown; still having trouble when postgres plugin test is run multiple times in a row. |

|
Rest of issue fixed on SVN 22285. |
