comment:1 by Remy Blank, 14 years ago

It looks like one revision between 1 and 100 has no date. But in that case, the value should be None and not undefined. Was this a one-off, or can you reproduce the issue consistenly? Any chance I could access the Trac instance and see the error page, showing the locals with the traceback?

comment:2 by Remy Blank, 14 years ago

Milestone: → next-minor-0.12.x

Additional info: this error happened while a resync was in progress (maybe more than one, see #9130). This is likely to be a race condition, and even though it is infrequent, we should try to avoid it.

comment:3 by Christian Boos, 14 years ago

Component: general → version control
Keywords: cache sync added
Priority: normal → high
Severity: normal → critical

Interesting, this is exactly what I've seen recently with the Babel Trac (ticket:5932#comment:25). Here we also have the PostgreSQL backend, like on t.e.o.

comment:4 by Christian Boos, 14 years ago

Milestone: next-minor-0.12.x → 0.12

Another occurrence of this issue detected on t.e.o/demo-0.12, the problem there was a missing revision r9202. For that Trac instance, the backend is SQLite.

Looking at the revisions in table revision, I found a mix of "int" and 0-padded string revs: 

... 
(u'0000009200',), (u'0000009201',), (u'9202',), (u'9203',), (u'9204',), 
(u'0000009205',), (u'9206',), (u'9207',), (u'0000009208',), (u'9209',), (u'9210',), 
..

Not sure how this happened.

Worse, when trying to do a resync to "fix" this problem, I got the following error: 

$ trac-admin ./trac-0.12 repository resync trac
Resyncing repository history for (default)...
ProgrammingError: Cannot operate on a closed cursor.

Trying to finish with a sync: 

$ trac-admin ./trac-0.12 repository sync trac
Resyncing repository history for (default)...
ProgrammingError: Cannot operate on a closed cursor.
$ trac-admin ./trac-0.12 repository sync trac
Resyncing repository history for (default)...
5371 revisions cached.
Done.

etc. it stayed at 5371.

In the db, repository.youngest_rev was u'5153', and: 

>>> list(c.execute("SELECT count(*) FROM revision WHERE repos=1"))
[(5371,)]
>>> list(c.execute("SELECT count(distinct(rev)) FROM node_change WHERE repos=1"))
[(5371,)]

The rows contained good looking 0-padded revisions, ending with the '0000005371' one.

After fixing the youngest_rev by hand, another sync was able to complete.

Very strange, very broken…

Replying to cboos:

$ trac-admin ./trac-0.12 repository resync trac

Can you please post the full traceback for this error? IIRC it should be in the log.

and then it completes to [9405].

Time to rethink my "bullet proof" resync algorithm :-(

comment:7 by Remy Blank, 14 years ago

Ah, so the "ProgrammingError: Cannot operate on a closed cursor" is a side-effect, and the actual error is "OperationalError: database is locked", which is interpreted as "revision already cached".

I'm puzzled about the other errors, probably due to concurrent sync requests. Especially by the fact that we haven't seen those errors before. AFAIR we haven't changed the sync algorithm (yet), except for the addition of the repos field.

Right, I believe the following change should fix this secondary issue:

I'm puzzled about the other errors, probably due to concurrent sync requests. Especially by the fact that we haven't seen those errors before.

Well, we have, it's #8067.

AFAIR we haven't changed the sync algorithm (yet), except for the addition of the repos field.

I don't think it's because of recent changes, the problem was always there.

Ok for #8067, but there we pointed to MySQL - MyISAM, which is clearly not the case here. The discussion there should be helpful in designing the sync-ng :-)

comment:10 by Christian Boos, 14 years ago

I was referring to the discussion in ticket:8067#comment:9 and ticket:8067#comment:10, and the reference to #4043 from there.

Milestone: 0.12 → next-major-0.1X

Worth a rewrite, but probably not for 0.12, neither for 0.12.x, realistically.

comment:12 by David Avsajanishvili <avsd05@…>, 14 years ago

I have other idea about source of this issue. In my case it happened when I have ADDED one file to fresh SVN, and then REMOVED it, so repository became empty. As a result, there was non-zero latest revision, but no files in it!

Here is my traceback:

Priority: high → low

Obviously low prio, as it hasn't seen any activity in two years.

Yet the problem seems to be real, so triaging as "known issue" that should be taken in consideration when (re)working on the versioncontrol cache sync code.
