[Trunk] database schema upgrade 6/7 -> 8 fails Loading a profile that was created with a nightly build before 2008-02-18 in a nightly build after 2008-02-18 will result in a popup error message: "An error was encountered preparing the calendar located at moz-profile-calendar:// for use. It will not be available.". Error Console shows additional messages, see below.

Possible workaround: 1. Open with the old working Sunbird/Lightning build 2. Export each calendar to iCalendar format and save the .ics file Note the URLs for remote calendars 3. Close Sunbird/Thunderbird 4. Delete the database file "storage.sdb" from profile 5. Start Sunbird/Thunderbird to create a new database file "storage.sdb" 6. Create new calendars and import the .ics files Resubscribe to remote calendars
Flags: wanted-calendar0.9?
Additional information: By adding dump() statements to the source code I can follow the upgrade procedure to the following line: tzId = getTzIds.row.zone; http://bonsai.mozilla.org/cvsblame.cgi?file=/mozilla/calendar/providers/storage/calStorageCalendar.js&rev=1.136&mark=1171#1152 I don't see any dump() output directly added after that statement. Seems the execution hangs/waits or has been aborted silently. Anyone knows why the statement mentioned above works on MOZILLA_1_8_BRANCH but not on Trunk?
This should definitely be fixed, but trunk bugs cannot become wanted/blocking0.9 by definition as it will be released from the branch.

Using the same Lightning builds as mentioned in Comment #0 but different Thunderbird builds I get the additional regression range: Works in Thunderbird 3.0a1pre (2008-01-10-03) Fails in Thunderbird 3.0a1pre (2008-01-11-03) Checkins during that range: http://tinyurl.com/45w8zt From a first glance I'd say Bug 406087 (update to sqlite 3.5.4) might be related.
Shawn, do you know if the SQLite update (Bug 406087) might be responsible for the mozStorage statement failure/hang mentioned in Comment #4 above?
There's *a lot* different from trunk to branch in storage. SQLite shouldn't have had an behavior change there. Can I see a stack trace of the hang (including JS stack please)?
See also regression range mentioned in Comment #6. The very same calendar code works on Trunk up to the 2008-01-10-03 nightly build but fails in the next nightly Trunk build. How do I create the requested JS stack? Currently all the code runs during application startup and I was only able to add some dump() statements in the code for debugging.
When you get the hang, attach gdb, then do the following two things: call DumpJSStack() bt The js stack will dump out to the console window you opened the application with, and the backtrace will dump out into gdb's terminal. I don't know how to do that on windows though...
When trying with a debug build the information I get is: 0[a94eb0]: BEGIN TRANSACTION 0[a94eb0]: WARNING: Unsafe use of LIKE detected! Please ensure that you are using mozIStorageConnection::escapeStringForLIKE and that you are binding that result to the statement to prevent SQL injection attacks.: file e:/dev/sb-trunk/mozilla/storage/src/mozStorageStatement.cpp, line 176 0[a94eb0]: SELECT DISTINCT(zone) FROM (SELECT recurrence_id_tz AS zone FROM cal_attendees WHERE recurrence_id_tz LIKE '/mozilla.org%' UNION SELECT recurrence_id_tz AS zone FROM cal_events WHERE recurrence_id_tz LIKE '/mozilla.org%' UNION SELECT event_start_tz AS zone FROM cal_events WHERE event_start_tz LIKE '/mozilla.org%' UNION SELECT event_end_tz AS zone FROM cal_events WHERE event_end_tz LIKE '/mozilla.org%' UNION SELECT alarm_time_tz AS zone FROM cal_events WHERE alarm_time_tz LIKE '/mozilla.org%' UNION SELECT recurrence_id_tz AS zone FROM cal_properties WHERE recurrence_id_tz LIKE '/mozilla.org%' UNION SELECT recurrence_id_tz AS zone FROM cal_todos WHERE recurrence_id_tz LIKE '/mozilla.org%' UNION SELECT todo_entry_tz AS zone FROM cal_todos WHERE todo_entry_tz LIKE '/mozilla.org%' UNION SELECT todo_due_tz AS zone FROM cal_todos WHERE todo_due_tz LIKE '/mozilla.org%' UNION SELECT alarm_time_tz AS zone FROM cal_todos WHERE alarm_time_tz LIKE '/mozilla.org%');
Attached file xpcshell testcase (obsolete) —
xpcshell testcase that shows the same behavior as observed above in calStorageCalendar.js by doing the same basic steps. Basically the code creates and initializes a mozIStorageStatementWrapper object and calls step() on it (line 64). When trying to read the row member of the wrapper object (line 69) the execution stops immediately. There is no sign for a hang. I hope someone can use it to debug the issue.
Keywords: testcase
It'll be a lot easier if you make this test run in |make check| like the rest of the storage tests (and a lot of your functions are needed either since they are provided by head_storage.js). It will certainly increase the likelihood of me looking at this sooner rather than later.
Attached file xpcshell testcase, v2 (obsolete) —
testcase can be run by copying it to mozilla/storage/test/unit and executing |make check|. The execution stops immediately at the line |var tzId = wrapper.row.zone;|

The execution stops immediately at the line |var tzId = > wrapper.row.zone;| Awesome! I was actually going to do that myself today. This bug is next on my todo list.
I can reproduce - not sure what's up though... Stepping through with gdb doesn't find it, but printing out the strings, I see they are equal. Looking for some JS folks to chime in.

Same failure using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.2pre) Gecko/2008070219 Calendar/0.6a1. Is there an possible workaround for the error, e.g. by changing the SQL query?
Summary: [Trunk] database schema upgrade 6/7 -> 8 fails [An error was encountered preparing the calendar located at moz-profile-calendar:// for use.] → [Trunk] database schema upgrade 6/7/8/9 -> 10 fails [An error was encountered preparing the calendar located at moz-profile-calendar:// for use.]
The error is in the wrapper code (but I'm not sure why). The workaround would be to use the mozIStorageStatement API's directly. I need someone more familiar with the JS engine to help me out with this since it's not clear why it's hanging.
Attached patch Possible fixSplinter Review
The reason for the problem here is that the code returns false from a JS hook without reporting an error. A minimized testcase would be either someMozStorageStatementRow[3] or someMozStorageStatementRow.foopy (where foopy isn't a column name). Also, if you set *_retval, you don't really want to return NS_ERROR_* because that'll override the exception that the JS engine threw.

Note - the issue with this test case is that the name isn't defined. You need to use "AS zone" in the SQL.
