I can't add any comment here. http://trac-hacks.org/ is giving me an error.

What is the error? Was it rejecting the content as spam? That is a known problem that we can't do much about atm, but it might help if you register for an account.

Your file reports a syntax error which is quite strange. I also have Trac 1.0 with SQLite and it works pretty well. What does that "13" mean in your error message OperationalError: near "13": syntax error ? Have you accidentally edited the file and inserted 13?

I could add comments and attachments after that. I'm sorry, but I didn't save the error I got. The http://trac-hacks.org is working now.

No, I didn't edited any file. I don't use to customize any Trac and/or plugin code. I don't know what that mean either. One detail is that if disable the "SmpRoadmapProject — Groups milestones by 'Project'" checkbox at the plugins' admin page, I can load the Roadmap page successfully. However, the unchecked feature is not being presented of course.

It was probably the common "database is locked error" then. That's another that doesn't have a quick fix, but usually the problem will go away after a short wait.

Can you open trac.db with Sqlitedatabasebrowser and tell me if table smp_milestone_project exists? What is the sources of your "build/bdist.linux-i686/egg/trac/db/sqlite_backend.py", line 48? A click on the callstack should tell you.

comment:9 Changed 12 years ago by Douglas Marquardt

The table exists. I used the Linux sqlite3 program to open the database and check the smp_milestone_project existence. It's there.

sdadm:/trac_root/db# sqlite3 trac.db
SQLite version 3.5.9
Enter ".help" for instructions
sqlite> .schema smp_milestone_project
CREATE TABLE smp_milestone_project (
    id integer PRIMARY KEY,
    milestone varchar(255),
    id_project integer
);

Please find below what it has at the line 48

43	    sqlite_version_string = sqlite.sqlite_version
44	 
45	    class PyFormatCursor(sqlite.Cursor):
46	        def _rollback_on_error(self, function, *args, **kwargs):
47	            try:
48	                return function(self, *args, **kwargs)
49	            except sqlite.DatabaseError:
50	                self.cnx.rollback()
51	                raise
52	        def execute(self, sql, args=None):
53	            if args:

no idea anymore :( Is milestone that goes into function get_project_milestone() maybe None here? Can you check this?

comment:11 Changed 12 years ago by falkb

or is 13 probably the name of the milestone or of the project?

comment:12 Changed 12 years ago by Jun Omae

It seems that the plugin has SQL injection. When the milestone name is Project'13, that issue probably will happen. We must not use string-formatting. See t:wiki:TracDev/DatabaseApi#Parameterpassing.

The example is the following. The other methods in model.py have still the same issue.

  • simplemultiproject/model.py

     
    208208                        smp_project AS p,
    209209                        smp_milestone_project AS m
    210210                   WHERE
    211                         m.milestone='%s' and
    212                         m.id_project = p.id_project""" % (milestone)
     211                        m.milestone=%s and
     212                        m.id_project = p.id_project"""
    213213
    214         cursor.execute(query)
     214        cursor.execute(query, [milestone])
    215215        return cursor.fetchone()
    216216
    217217    def get_id_project_milestone(self,milestone):

Jun's patch looks good to me.

(In [12659]) bugfix (refs #10890): removed possibility of SQL injections; plugin likely can stand project names like Project'13 now, thanks to jun66j5

comment:17 Changed 12 years ago by falkb

@Douglas: please, test! @jun66j5+rjollos: please, review! TIA

Yes, there are milestones with the current year out there, like "SD/DECS June'13 Release IT1"

I've never applied a patch before. Can you teach me?

comment:20 Changed 12 years ago by falkb

You just have to download the latest version, or update from SVN. I've committed the patch already.

comment:21 Changed 12 years ago by Douglas Marquardt

I downloaded the latest version and updated my Trac instance. All is working fine now. Thank you very much for all the help.

Resolution: fixed
Status: assignedclosed

You're welcome. It's another piece in the puzzle of stability. Kudos to jun66j5.

comment:23 Changed 12 years ago by falkb

(In [12662]) bugfix (refs #10890): further testing revealed [12659] was not fully water-proofed, this should fix the project_id SQL argument (dougbm, please update again)
