Description

I am encountering numerous problems on Windows 8 (x64) running TracD with Python 2.7.

In Internet Explorer 10, loading Trac pages is erratic, with first load often missing style/layout or missing the header logo. Pressing back then forward several times may resolve this problem as if little bits of the page are building up in the cache over time. (The logo will load if right-clicked to Show Picture).

With the WikiExtras hack, the [WikiIcons] documentation fails to load all icons in the page, but will load them eventually with back/forth as above (or by right-click Show Picture). However, hitting the Refresh button will crash TracD/Python.

The Trac service may stop responding randomly, at which point it is reported that the Trac database needs to be upgraded. (Running an upgrade allows the wiki to display, but all macros are now unrecognized and the custom logo becomes undefined, so this is probably spontaneous corruption).

These problems are also evident with Google Chrome, so it does not appear to be IE10 specific. I should note that IE10 is aggressive - with a tracking protection list turned on, the Trac header logo is blocked.

Compatibility settings on executables has not helped, nor has making exceptions in Antivirus/Firewall. An identical setup was working fine in Windows 7 (x64).

Update: I captured some error messages running TracD in a administrative command prompt directly rather than as a Service (with SVRANY, in case that was the problem).

Well, Trac of course can't operate reliably (or at all) if the connection to the DB (SQLite) is not working. So I'd suggest to investigate first the SQLite3 / Windows 8 possible issues. You could maybe upgrade to the latest Python 2.7 release (2.7.3 I think), to see if it helps. You could also try using another database (MySQL/MariaDB or PostgreSQL, whichever you prefer or is known to work on Windows 8).

comment:4 by paulcoddington@…, 12 years ago

Just confirmed that the problem with TracD persists with python.org 2.7.3 (previously was using Active Python 2.7.2).

The problem with SQLite has not appeared again so far, but was infrequent compared to the socket problem which happens continuously.

Also confirmed Apache working fine (quick and dirty install with Bitnami package), so this is a workaround I am currently investigating.

Looking at this again this morning, I suspect this is probably better reported to the Python group, as it seems to be a problem with the socket implementation and is likely to affect any application using sockets.

Replying to paulcoddington@…:

Looking at this again this morning, I suspect this is probably better reported to the Python group, as it seems to be a problem with the socket implementation and is likely to affect any application using sockets.

If you do, better first try to reproduce on a simple example without Trac, demonstrating the failure (e.g. using the ​SimpleHTTPServer). Otherwise it's very likely that your report will get dismissed as a Trac bug…

comment:6 by paulcoddington@…, 12 years ago

Additional tests since last post:

  1. Update SQLite.dll used by python, loading error persists.
  2. Update to PSF Python 2.7.3 served by Apache 2.2, loading error persists (but no crashes, no corruption).
  3. Built-in tests for Lib modules socketserver.py and socket.py passed, no errors.
  4. SimpleHTTPServer, no errors (3,000 icons in simple generated HTML page).

Also, I can't replicate my earlier apparent success with Trac Stack (perhaps I forgot to clear the browser cache and thought it was working?).

comment:7 by Christian Boos, 12 years ago

Then we have to figure out the difference between SimpleHTTPServer and tracd. One of the main differences would be the ThreadingMixin. Can you disable that? (see e.g. ticket:2598#comment:8).

comment:8 by paulcoddington@…, 12 years ago

One of the quirks of the python.org distribution is that it keeps most things installed as eggs rather than unpack them. I have altered the standalone.py file in the egg, but the entire ...\trac\web folder is not being unpacked to the egg cache while viewing the wiki. In any case, no difference.

comment:9 by Christian Boos, 12 years ago

Can you post again a trace like in comment:1, with multithreading disabled (to verify that multithreading is really disabled… i.e. we shouldn't see garbled messages strings).

Not having much success approaching this from the Windows end - not a lot of detailed Windows 8 documentation out there. I know sockets have changed a lot in their implementation for this release, and it may be that there is more aggressive flood protection leading to dropped packets, but I haven't found a way to detect if this is the problem.

Replying to paulcoddington@…:

See? Still the garbled output that is typical when you get output to the console window from a multithread app. Somehow the patch is not applied to the right file.

Instead, I'd suggest you install from source, or simply unzip the source distribution. Well, there's nothing to install really, you could just go at the top of such a source extraction, and do (in a cmd.exe shell): 

> set PYTHONPATH=.
> python trac/web/standalone -p 8000 -e ...

Also, about the "No handlers…", I wonder how this could be indicative of another problem. What's the content of your [logger] section in your trac.ini file?

HANG

Now this is a very interesting result.

The socket error is gone, but the process HANGs at the end of every page. When the process is terminated (Task Manager), the browser seems to display the complete page with no errors. The process is restarted and the next page is selected - hang, terminate, page is drawn. Even the troublesome icon page loads completely without a socket error.

As for the log error, I don't have a [logger] section, instead:

[logging] log_type = none log_file = trac.log log_level = WARNING

Interesting indeed. Can you try with --http10?

Ctrl-C

OK, I tried this a few times to be really sure…

I cleared the browser cache, started the server with --http10 and WikiStart loaded very slowly, without layout or images.

Then I left Trac (went to Google, as before), cleared the cache, went back to Trac and found every page loaded perfectly in reasonable time (not really fast, but not painfully slow either).

So I Ctl-C'd the process, cleared my cache again, then restarted - perfect results first time. Confirmed several times.

It is almost as if something had adapted.

Also, there were no console messages displayed in --http10 mode.

comment:16 by Christian Boos, 12 years ago

Milestone: → 1.0.2
Priority: normal → high

Ok, be careful here, maybe you won't always be able to kill all processes with CTRL+C (we have r10504 but I'm not sure that's always enough). So it might be that you still have a python process running "in the background" especially if you started tracd once with -r. So always check what you have in the process explorer, to be sure. Because you should see the same kind of output in the console than with the default --http11 mode…

So tracd with --http10 and multithreading disabled is not the fastest way, but it should be more robust… and it apparently is. So this gives us a good base.

"Good news"… I just started it non-multithreaded with --http11 and now it also hangs for me! I might be able to troubleshoot that further this evening…

In the meantime, you could try to use it with --http10 and with the ThreadingMixIn, I suspect this should work and be reasonably fast.

We might just have uncovered a bug in the --http11 mode which was not apparent in the normal multi-threaded case (until Windows 8, that is).

comment:17 by paulcoddington@…, 12 years ago

OK - I'm being a bit more diligent about killing processes this time (Sysinternals pskill python.exe with Task Manager check). Also, fresh boot this morning.

In multithreaded --http10 mode, images are still failing to load, but the trace is different (no socket error, but missing items return 500 not 200).

And we are getting console output this time.

http10 Multithreaded

Fast, some items not loading, no socket error, 500 error instead.

Looks like my workaround is to run non-multithreaded for now. It is fast enough for most pages, as not many pages in my wikis are as intense as WikiExtras docs.

comment:18 by paulcoddington@…, 12 years ago

This raises the question of how to apply this workaround to an Apache hosted system.

Now that I have figured out Apache (in the attempt to fix this), I am wondering if it will be better than TracD. It seems to have a small footprint in minimal configuration, and raises fewer questions about how to set the Firewall (runs as httpd.exe rather than some combination of python.exe/tracd.exe/svrany.exe).

comment:19 by paulcoddington@…, 12 years ago

Also, I am wondering if the socket error we saw in the first instance is skipping over closing the sockets - the memory used by the process increases with every page view.

in reply to:  16 ; comment:20 by Christian Boos, 12 years ago

Replying to cboos:

We might just have uncovered a bug in the --http11 mode which was not apparent in the normal multi-threaded case

The "problem" with the non-multithreaded case was that … this code was not meant to be non-multithreaded ;-)

In tracd we rely on the Python standard library mechanisms. We call BaseServer.serve_forever() which basically loops on incoming requests and address each with a call to BaseServer._handle_request_noblock (in the standard ​SocketServer.py). As its name suggests, this is normally non-blocking, as the method BaseServer.process_request which it calls is reimplemented by either the ForkingMixIn or the ThreadingMixin. We use the latter, as the former doesn't work on Windows. The problem is that in the HTTP/1.1 mode, we never close the connection ourselves until the client does it, and this can take quite a long time since generally the browsers keep them around a few minutes "just in case". See we keep looping in BaseHTTPRequestHandler.handle and never go back to the main loop in serve_forever. Not so a problem in the multi-threaded case, but this is what gives the impression of a hang in the single-threaded case.

I nevertheless toyed around and managed to make it work reliably in the single-threaded case. See:

[b42a6847/cboos.git] wsgi: don't waste time blocking on connections on which there's nothing to read from…

I think closing an inactive connection should be always a win, even in the multi-threaded case. It's a compromise between the HTTP/1.0 way of closing the connection after each request and the HTTP/1.1 way of keeping it alive as long as the client keeps it alive: here we keep it alive only as long as it gets actively reused, so generally during the time span of an initial request and all its secondary requests, but not more.

That change addresses the "hang" situation observed in this non-standard single-threaded case and the remark in comment:19 about the sockets being kept opened. I'm not sure this is enough to completely address the memory increase issue, but it should help (note: the memory increase problem used to be much worse, and in practice we don't consider it to be a problem anymore these days).

I'm also not sure this will help with original problem reported here, which happens when flushing what's left to be sent to the client… We could also add some exception catching clauses there, but that might just hide a real issue.

Let's first see how it works on your side with that b42a6847 change, with --http11:

  • in the single-threaded case,
  • in the normal multi-threaded case

Replying to cboos:

I just found ​PythonBug:14574 which does just that. But same remark, it doesn't explain why those disconnects happen in a systematic way for you.

In which case, the following will help:

Both threading modes with --http11 seem to be working fine at my end (and single-threading mode seems a lot faster than it used to be).

I am not seeing any errors in the log.

Great to hear! If you look at the network panel in the developer tools of your browsers, do you actually see all the requests having completed correctly (after having cleared the browser cache)? Also for the WikiExtras pages?

Btw, if someone remembers why we had IOError in the exception catching clauses, and not just socket.error, I'll be glad to have my memory refreshed ;-) It seems that even on Windows the 10053 one is a socket.error.

comment:25 by paulcoddington@…, 12 years ago

Bad news - the multithread --http11 is fragile. It can work fine for a while, then have 500 errors by the score. Reliability seems to change with each service restart and each reboot (sometimes the odd error, sometimes many, sometimes none).

In all cases, if you hit the refresh button in the browser repeatedly (at reasonable intervals), the 500 errors increase. If you are using the original SQLite.dll bundled with Python, about 3-4 refreshes will crash Python (with the latest SQLite.dll there is no crash, but 500 errors still increase).

comment:26 by paulcoddington@…, 12 years ago

The single thread -http11 seems stable under repeated tests, BTW.

comment:27 by anonymous, 12 years ago

I am feeling a bit paranoid about the apparent inconsistency - starting tomorrow, I am planning on putting aside the current system image under construction to archive/backup and starting over with a bare-metal reinstallation of Windows 8 for further testing in case something has gone subtlety wrong with this one. Should have the results of that test in about a day or so.

So these 500 correspond to what, in the trac.log?

Also, do you have any kind of other software which might interfere? An anti-virus of some sort? Firewall? Parental protection software? ;-)

comment:29 by Christian Boos, 12 years ago

Any news? Did you try on another machine by any chance? Still wondering if it's a generic issue with Windows 8 or just your particular setup (I don't have 8 so far, and I'm more than happy with 7).

comment:30 by paulcoddington@…, 12 years ago

Sorry about the delay - I have been keen to get my migration to Windows 8 / VS 2012 out of the way. Now that I'm done with that, I can look into this more easily using my Virtual Machine test bed.

I'll be back on the case soon, I promise (:P).

Have you been able to revisit the issue? We are closing in on milestone:1.0.2, so we'll need to do something with this ticket soon - move it forward or close it.

comment:32 by Paul Coddington, 11 years ago

Sorry about the delay.

The problem seemed to go away a few system image maintenance passes down the track. So, a combination of Windows Updates to around August, plus an update to Python 2.7.5 seemed to fix it (one other difference with Python - the Win32 extensions pack is now installed).

So far, on Windows 8.1 RTM with Python 2.7.5 it seems OK.

Thanks for taking care of this. It is much appreciated.

comment:33 by Christian Boos, 11 years ago

Milestone: 1.0.2 → 1.1.2

Thanks for the feedback! Switching to Python 2.7.5 might have helped for silencing the errors regarding the disconnects (fix for ​PythonBug:14574 was integrated for 2.7.4), and if the root problem is gone as well, that was probably thanks to the Windows updates.

I looked again at my changes, I'm not so sure anymore about [b42a6847/cboos.git] as this was only really needed in the artificial non-multithreaded situation and might hurt performance when we're doing AJAX calls. The rest seems still fine however I think that these are now more suited for trunk than for 1.0-stable.

comment:35 by Christian Boos, 10 years ago

It's now been a while I'm running stock tracd on Windows 8.1 x64, but I looked again at cboos.git@t11049-tracd-enhancements and the changes there seem to be worthwhile nevertheless, except perhaps for [b42a6847/cboos.git].

So keeping it on the milestone.
