| 00:28 | <hatchmt> | I have been unable to compile svn r14830+ using procopt on my athlon system. r14829 compiles just fine, and r14830+ compiles fine if I remove procopt and use march=i386. Has anyone else run into problems with compiling svn past that release? The changeset says the linker is now using the mythav* libs when linking mytharchivehelper (where my compile fails). |
| 00:30 | <hatchmt> | I am using a somewhat non-standard method of compiling it, however... My configure line is as follows: |
| 00:30 | <hatchmt> | ./configure --compile-type=release --enable-mmx --prefix=/usr --libdir-name=lib --x11-path=/usr/include --enable-joystick-menu --enable-ivtv --enable-firewire --enable-dvb --dvb-path=/usr/include/v4l/ --enable-audio-oss --enable-audio-alsa --enable-audio-arts --enable-audio-jack --enable-x11 --enable-xrandr --enable-xv --enable-xvmc --enable-xvmc-vld --enable-xvmc-pro --enable-opengl-vsync --disable-directfb --enable-libdts --enab |
| 00:30 | <hatchmt> | le-proc-opt --with-bindings=perl |
| 00:31 | <hatchmt> | this worked perfectly pre-14830 |

| 07:10 | <clever> | DaveMorris: yeah there is a bit too many tables:P |
| 07:10 | <clever> | DaveMorris: i just -v database and guess from what it looks at |
| 07:25 | <gbee> | there aren't _enough_ tables, if we were to truly rationalise the database there would be several more |
| 07:45 | <DaveMorris> | then why don't you? |
| 07:46 | <stuarta> | work in progress is the database for myth |
| 07:50 | <stuarta> | hmmm, that was kinda yoda that statement |
| 07:51 | <DaveMorris> | I noticed |
| 07:51 | <DaveMorris> | is there a list of the planned work? |
| 07:51 | [~] | stuarta checks to see if his brain rolled under the desk |
| 07:52 | |-| | CDev [n=CDev@c-71-233-206-26.hsd1.ma.comcast.net] has joined #mythtv |
| 07:52 | <stuarta> | list? not really, just a general consensus of what needs doing to what bit |
| 07:56 | <DaveMorris> | I wanna patch my version of mythtv to keep tvlistings in the program table for longer than is currently set. Can someone give me some pointers of the top of my head where I should start looking in the code? |
| 07:57 | <stuarta> | housekeeper, iirc programs/mythbackend |
| 07:58 | <clever> | the guide in my digital box keeps NOTHING from the past |
| 07:58 | <clever> | i cant even tell what show just ended 30 seconds ago |
| 07:58 | <clever> | useless crap:P |
| 07:59 | <stuarta> | that's by design ;-) |
| 07:59 | <clever> | in mythtv i can easily go back a day or more in the guide |
| 08:00 | <clever> | and DaveMorris's patch will probly let him go back even further |
| 08:00 | <clever> | at the expense of slower resched's |
| 08:00 | <clever> | and ive found a flaw in the sheduler design |
| 08:00 | <stuarta> | probably a feature |
| 08:00 | <DaveMorris> | yeah I wanna see how much it affects it |
| 08:00 | <clever> | ive set a show to keep at most 2 recordings and to stop recording after the limit is reached |
| 08:00 | <clever> | stuarta: yet its clearly shedules atleast 6 episodes to record |
| 08:01 | <stuarta> | not for me |
| 08:01 | <clever> | what revision number? |
| 08:01 | <stuarta> | head from last 2 days |
| 08:02 | <clever> | 15192M trunk |
| 08:02 | <janneg> | clever: I don't think we have that feature |
| 08:02 | <clever> | then why does it do that on stuarta's box:P |
| 08:02 | <stuarta> | janneg: we do have that. it's great. |
| 08:02 | <stuarta> | clever: i'll update and recheck my schedule. |
| 08:03 | <clever> | ive also noticed a bug in the auto expire |
| 08:03 | <clever> | http://www.pastebin.ca/825018 |
| 08:03 | <clever> | it appears to have moved to the deleted group then actualy deleted it |
| 08:03 | <janneg> | I think we have only auto expire older recordings and always keep the x newest |
| 08:04 | <clever> | also the 0mb it deleted was actualy way more and was falsely deleted for being a peice of crap left by a livetv |
| 08:04 | <clever> | this looks more like cleanup of the 500 2mb files livetv may tend to make |
| 08:04 | <clever> | but was actualy a normal recordign that got interupted(ctrl+c'ed) |
| 08:04 | <stuarta> | clever: have you actually recorded the 2 shows yet? |
| 08:05 | <clever> | stuarta: no i have 0 copys of that show recorded |
| 08:05 | <stuarta> | thats why |
| 08:05 | <clever> | stuarta: but once 2 record its going to stop all the others |
| 08:05 | <stuarta> | yup |
| 08:05 | <clever> | so why even show them as being scheduled:P |
| 08:06 | <stuarta> | because they are all candidates until you hit max episodes |
| 08:06 | <gbee> | anyone who thinks as much of python as I do, might find this amusing: http://xkcd.com/353/ |
| 08:06 | [~] | DaveMorris wonders if RT could do sql injection to drop the mythconverg database? |
| 08:07 | <clever> | gbee: seen it before |
| 08:07 | <clever> | DaveMorris: RT? |
| 08:08 | <gbee> | DaveMorris: no, we use prepared statements |
| 08:08 | <janneg> | clever: where is the bug in the pastebin auto expire log snippet? |
| 08:08 | <gbee> | clever: figured that a few people had seen it before, but that I might not be the only one who hadn't |
| 08:08 | <janneg> | gbee: not everywhere |
| 08:09 | <stuarta> | i hadn't |
| 08:09 | <clever> | janneg: it appears to have deleted the same chunk of the show twice(to the deleted group then realy deleted) |
| 08:09 | <janneg> | clever: which one? |
| 08:09 | <gbee> | janneg: no, not everywhere but those places we don't are a minority and generally get fixed when someone sees them |
| 08:10 | <clever> | janneg: lines 3 and 8 |
| 08:11 | <janneg> | clever: no that are two different files |
| 08:11 | <DaveMorris> | clever: radio times |
| 08:11 | <clever> | DaveMorris: never heard of them |
| 08:11 | <DaveMorris> | they do tv listings for the UK |
| 08:11 | <janneg> | due to the signalmonitor design two recordings are created |
| 08:12 | <stuarta> | that we need to fix |
| 08:12 | <clever> | janneg: lines 3 and 8 are both 1020 '20 02:00:00 2007' which apears to be referencing the same time |
| 08:13 | <clever> | lines 1/2 are a seperate file for the rest of the show |
| 08:13 | <janneg> | gbee: the BUSQ don't use prepared statements evertwhere |
| 08:13 | <clever> | the backend was having problems so i restarted it durring a comercial cuting it off mid recording |
| 08:13 | <clever> | and it resumed when it started back up |
| 08:13 | <janneg> | clever: but the filesizes differ |
| 08:13 | <clever> | then went and deleted both halves on me:P |
| 08:14 | <clever> | yeah thats because its in 2 halves |
| 08:14 | <clever> | the 0byte one was 90% of the show |
| 08:14 | <gbee> | janneg: hadn't remembered that, but that's one query I won't get near enough to convert |
| 08:14 | <clever> | janneg: if you look closely youll see the 21mb one being deleted twice |
| 08:14 | <gbee> | shame though, since there is supposed to be some performance benefit to using stored prepared queries |
| 08:15 | <janneg> | gbee: me neither |
| 08:17 | <janneg> | clever: no, it's not delting the 21mb file twice. and the autoexpirer doesn't move to the deleted |
| 08:18 | <clever> | but it is showing 2 lines referencing the 21mb one and delete |
| 08:18 | <clever> | a few 10th's of a second appart |
| 08:19 | <janneg> | and it is showing these two lines for every other recording too |
| 08:19 | <clever> | ahh |

| 08:57 | <GreyFoxx> | gbee: Well now I know why I see a upnp regrab for mysql data anytime mythweb triggers a preview screenshot to be made |
| 08:58 | <GreyFoxx> | we are building a commandline in the PreviewGenerator and then exec() ing a call to launch mythbackend to generate it rather than call the code directly |
| 08:59 | <GreyFoxx> | and so for everytime PreviewGenerator::Run() is called we rediscover the DB info :) |
| 09:00 | <GreyFoxx> | At least that's my theory so far :) |

| 09:12 | <GreyFoxx> | we have a --disable-autodiscovery for frontends, but no such command for the backend to ask it to skip that |
| 09:12 | <GreyFoxx> | If we get to the point of calling it in the preview generator then we obviously already have the info so we don't need to keep discovering just to generate a preview |

| 11:22 | <hatchmt> | It crashes when working on mutharchivehelper |
| 11:22 | <hatchmt> | mytharchivehelper* |
| 11:24 | <gbee> | hatchmt: compiling just fine on 1x 32bit Athlon and 2x 64bit Athlons (one of those a Turion) |
| 11:24 | <hatchmt> | hmmm |
| 11:26 | <hatchmt> | the configure line I'm using is as follows: |
| 11:26 | <hatchmt> | ./configure --compile-type=release --enable-mmx --prefix=/usr --libdir-name=lib --x11-path=/usr/include --enable-joystick-menu --enable-ivtv --enable-firewire --enable-dvb --dvb-path=/usr/include/v4l/ --enable-audio-oss --enable-audio-alsa --enable-audio-arts --enable-audio-jack --enable-x11 --enable-xrandr --enable-xv --enable-xvmc --enable-xvmc-vld --enable-xvmc-pro --enable-opengl-vsync --disable-directfb --enable-libdts --enab |

| 11:27 | <hatchmt> | I'm going to try to compile it just running configure with no operands |
| 11:30 | <gbee> | hatchmt: shouldn't need to force mmx, it should be enabled automatically if your CPU supports it - not that I think it's causing the problems here |
| 11:31 | <hatchmt> | agreed |
| 11:31 | <hatchmt> | I didn't remove that when I appended my script to use proc-opt |
| 11:31 | <gbee> | nor should you need to enable firewire/dvb or most of those options since they are enabled by default, again, that won't cause the problems you are seeing |
| 11:32 | <gbee> | it will just cleanup your configure args |
| 11:33 | <hatchmt> | Indeed |
| 11:33 | <hatchmt> | Well, I'm building it with just 'configure --enable-proc-opt' just to see what happens |

| 12:30 | <stuarta> | gotta run. |
| 12:30 | <stuarta> | back tomorrow |
| 12:38 | <hatchmt> | gbee: it does seem to succeed by installing the mythtv libs first and compiling against that as opposed to the build directory. |
| 12:38 | <hatchmt> | the problem is |
| 12:38 | <hatchmt> | I compile against the build location because it builds an rpm. |
| 12:40 | <gbee> | hatchmt: do you run make distclean first? I suspect that there may be some cruft in your build directory |
| 12:41 | <hatchmt> | the spec file removes the build directories first, then does an svn checkout and goes from there. A distclean shouldn't be necessary |
| 12:49 | <hatchmt> | here's what the spec does: |
| 12:50 | <hatchmt> | it builds mythtv as usual |
| 12:50 | <hatchmt> | then it creates a directory 'temp', sets temp=`pwd`/temp |
| 12:50 | <hatchmt> | then 'make -C mythtv-%{version} install INSTALL_ROOT=$temp' |
| 12:51 | <hatchmt> | export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$temp%{_libdir} |
| 12:51 | <hatchmt> | cd mythplugins-%{version} |
| 12:51 | <hatchmt> | and then configure and make as usual |
| 12:52 | <hatchmt> | that's where the prefix in the configure points to /usr/src/redhat/BUILD/mythtv-0.21/temp/usr |

| 16:14 | <clever> | CDev_: you could just use msg queues but those might be more complex |
| 16:15 | <gbee> | this came up 18 months ago, in a discussion about replacing myth protocol |
| 16:15 | <clever> | CDev_: i beleive msgqueues let you throw structs onto a queue then pull them off |
| 16:15 | <clever> | the que id is made based on the inode of a selected file+a uniq id |
| 16:16 | <clever> | msg queues and dbus i dont think work over a lan |
| 16:16 | <gbee> | CDev_: what are you thinking of using it for? |
| 16:16 | <clever> | yeah it seems simple to just stuff more into the myth protocol |
| 16:17 | <janneg> | CDev_: D-Bus should wait for qt4 port |
| 16:17 | <janneg> | the simplest and probably most common IPC for are pipes |
| 16:18 | <clever> | depends on the task mainly |
| 16:20 | <Chutt> | i'd prefer to get qt4 in there first, then we'd just use the qt dbus stuff |
| 16:21 | <clever> | sounds good:) |
| 16:21 | <laga> | maybe jochen can be of some assistance :) |
| 16:22 | <sphery> | GreyFoxx: http://svn.mythtv.org/trac/ticket/3361 . Daniel just committed hte patch that makes preview generation a separate process (so that an ffmpeg crash doesn't take down the backend) in [15029] (2 weeks ago). |
| 16:24 | <clever> | ive never had ffmpeg tear the backend down |
| 16:24 | <clever> | but i have noticed those seperate procs are segfaulting on there own alot more lately |
| 16:25 | <sphery> | GreyFoxx: It seems that the current approach (even after fixing the recursively recursive searches) has some issues--especially since MythWeb now uses its own previews rather than the ones used by the frontend |
| 16:25 | <clever> | also when i open mythweb |
| 16:26 | <CDev_> | sorry for the delay... had a meeting I had to go to. |
| 16:26 | <clever> | mythbackend starts sucking system cpu usage |
| 16:26 | <sphery> | GreyFoxx: so going to the MythWeb Recorded Programs page will generally causes a ton of preview generation requests (through the UPnP code). I don't know if it's the process creation or UPnP client create/destroy that's killing it. Hope this helps. |
| 16:26 | <clever> | and doesnt stop till i restart it |
| 16:27 | <CDev_> | I want to change the upnp SSDP functionallity to be a daemon so it can be used by many processes. |
| 16:27 | <clever> | LOL |
| 16:28 | <clever> | ive got dos running on my 1.8ghz core2 duo |
| 16:28 | <clever> | with an old qbasic prog i made to render in 3d |
| 16:28 | <clever> | and its still takes several seconds to render! |
| 16:28 | <clever> | probly needs more sse/mmx:P |
| 16:29 | <clever> | wait that was loading |
| 16:29 | <clever> | it actualy redraws pretty fast |
| 16:29 | <Dibblah> | "therwise I will have to install another program instead of mythtv" - Oh, yes, emotional blackmail really works when... Noone else cares ;) |
| 16:29 | <Dibblah> | clever: Don't you want to be in -users? |
| 16:29 | <clever> | im just bored:P |
| 16:29 | [~] | clever goes to play with it silently |
| 16:30 | <sphery> | GreyFoxx: I suppose fixing the UPnP/autodiscovery stuff (related to preview gen) should be the first thing. If that doesn't fix it, maybe we need a Myth Preview Daemon started automatically by mythbackend and re-started in the event of a crash, with the preview generation queue managed by the backend or in a new table in the DB (since we don't have enough tables :) |
| 16:33 | <CDev_> | I guess I missed some of the discussions as to why the preview generation was changed to exec the backend multiple time? Wasn't it working fine when it was handled in the main process? |
| 16:34 | <Anduin> | CDev_: occasionally ffmpeg would crash while generating the preview, killing the whole backend |
| 16:35 | <sphery> | Right. See http://svn.mythtv.org/trac/ticket/3361 |
| 16:36 | <CDev_> | Wouldn't proper exception handling take care of the rare crashes? |
| 16:36 | <Chutt> | C |
| 16:36 | <Anduin> | and no SEH |
| 16:37 | <CDev_> | Seems like a extream solution. I'd rather find and fix why ffmpeg crashes. |
| 16:37 | <Chutt> | that's... difficult :p |
| 16:37 | <Chutt> | but, yeah, would be better |
| 16:40 | [~] | CDev_ feels like he has been away for a long time! |
| 16:41 | <CDev_> | upnp in SVN head is definitly broken. |
| 16:41 | <sphery> | Does it make sense to also have the backend auto-generate a MythWeb-sized preview after recording (as it does now for the frontend preview)? This, of course, assumes there's a standard (per-system?) size for MythWeb previews. |
| 16:41 | <CDev_> | I just hope I can find the time to fix it before the release date. |
| 16:41 | |-| | splat1 [n=splat1@rf1.splat1.com] has joined #mythtv |
| 16:42 | <CDev_> | sphery: The webmethod allows generation of any size... I know mythweb uses at least 2 different sizes. (I don't know if it's user changable) |
| 16:43 | <janneg> | CDev_: fixing code operating on random data is hard |
| 16:43 | <CDev_> | janneg: Isn't that what makes programming fun! :-p |
| 16:44 | <sphery> | Yeah, but since MythWeb requests a lot of previews at once when going to Recorded Programs, if it uses standard sizes, we could pre-generate them. We did that for the frontend because of the UI delay when scrolling through the Watch Recordings screen. |
| 16:44 | <CDev_> | I would think if we could find an example of when it crashes, there would be a possiblity of it being re-creatable. |
| 16:44 | <janneg> | forking the preview generator thread instead of exec a new backend should avoid the overhead and work too |

| 16:47 | <CDev_> | Chutt: Does it make sense to wait until after the next release to continue the QT4 port? with all the changes being made, it will take all of my time just to keep the branch up-to-date. |
| 16:48 | <Chutt> | whatever you want to do with it, really |
| 16:49 | <sphery> | I'd expect far more people would be interested in UPnP for 0.21 than for QT4 for 0.21. :) |
| 16:49 | <janneg> | CDev_: that was my original plan but I plan to work on the qt4 branch in the next two weeks |
| 16:52 | <CDev_> | Personally, I would like to see (after the release) the buy in of all the developers to bite the bullet and merge the branch with trunk sooner rather than later. There are just too many changes to keep in sync with head. |
| 16:53 | <CDev_> | sphery: I agree... That is why I'll try to spend time (what little I have) on the upnp code until the release. |
| 16:54 | <sphery> | All the users on the list complaining about UPnP not working in PS3 or TV recordings being in the Music section and not playable in XBox 360 will be very pleased with that decision. |

| 16:58 | <sphery> | I'm thinking, though, that's it's likely different symptoms (for different clients) of a larger problem related to the large number of changes to the UPnP code for the autodiscovery/Mac port/etc. |

| 17:16 | <gbee> | sphery: the point of the upnp preview gen as used by mythweb is that it can ask for any size image, mythweb uses a couple of different sizes I think, one for the recordings list and another for the details page (just catching up on scrollback, so if I'm repeating what's already been said, sorry) |

| 18:12 | <laga> | it'd be great if that was fixed. we'll have a status icon application in mythbuntu 8.04 |
| 18:12 | <laga> | which will poll the built-in httpd |
| 18:12 | <sphery> | If my changes did increase the frequency of the crashes, I'm pretty certain it's due to the QProcess stuff (which I basically copied from your mythfilldatabase/XMLTV capabilities stuff). |

| 18:14 | <sphery> | laga: I wrote 2 scripts--myth_recent_recordings.pl and myth_upcoming_recordings.pl--that use the Perl bindings to retrieve the info using Myth protocol (which is much more stable). |

| 18:15 | <laga> | sphery: i'll forward that to the code monkeys |
| 18:15 | <sphery> | I'm making changes now that will allow the backend to provide info about whether anything is currently recording and what jobs are running, etc. I'll probably make that available through the protocol, and in the Perl bindings. |
| 18:16 | <sphery> | the scripts are currently in contrib/misc_status_info (as they were examples of how to create scripts to add additional information to the backend status page). |

| 18:17 | <sphery> | gbee: Yeah. I didn't take it personally--just confessing that there may be some QProcess instability for those using the misc status script as I saw a couple of crashes during testing (but didn't have good BT's for them), so I can't tell if it's the "normal" crashes or new ones... :) |
| 18:18 | <sphery> | I just finished setting up a real dev system (finally--should have done that years ago), so I'll be much more cavailier about my testing (and more likely to be using a debug build when I get a crash). |
| 18:19 | <sphery> | laga: If my changes get committed before 0.21, the changes required to get recording/job status with the Python bindings would be as straightforward as the changes for the Perl bindings (so someone with Python experience could easily add it to Python bindings). |
| 18:20 | <sphery> | gbee: Did you notice any instability when you used QProcess for the tv_find_grabbers stuff? |
| 18:20 | <gbee> | we use QProcess in mythfilldatabase and mythtv-setup for the xmltv, I've not heard of any problems with it but then those apps are run repeatedly in a short timeframe |
| 18:20 | <gbee> | heh |
| 18:21 | <gbee> | not seen any instability, not a single crash when I was testing and none have been reported |
| 18:22 | <janneg> | has someone the url to retrieve pixmaps over xml handy? |
| 18:22 | <sphery> | Yeah. That's part of why I didn't ask when I was testing my code--since it's run very infrequently, it may not have had ample opportunity to crash. |
