| [02:42:43] | tgm4883: | Guyverix, Beirdo sphery no, those are bad settings |
| [02:43:08] | tgm4883: | just FYI, the one that resolves the innodb issue is "innodb_flush_log_at_trx_commit = 2 " |
| [02:43:12] | tgm4883: | the rest dont matter |
| [02:43:20] | Beirdo: | huh? |
| [02:43:25] | tgm4883: | but that's a bad fix according to everyone I've asked |
| [02:43:43] | Beirdo: | I haven't even looked at the settings yet |
| [02:43:43] | tgm4883: | Beirdo, the mysql settings for innodb database engine |
| [02:43:52] | tgm4883: | Beirdo, I just saw them at http://www.mythtv.org/wiki/Tune_MySQL |
| [02:44:04] | Beirdo: | knightr_: what issue? |
| [02:45:08] | Beirdo: | tgm4883: well, I think I'd actually listen to Guyverix on this. He's a mysql DBA as a (far too large) portion of his day job |
| [02:46:01] | Beirdo: | saying that those don't matter doesn't make sense to me anyways, there are plenty of mysql tuning blogs and sites that indicate much of the same settings |
| [02:46:16] | tgm4883: | Beirdo, that's great, and while it does resolve the issue and probably does little damage to a mythtv database, it's not the best fix |
| [02:46:34] | tgm4883: | Beirdo, I'm not saying they don't matter in a larger context |
| [02:46:55] | tgm4883: | I'm saying that the only one that matters in my testing was innodb_flush_log_at_trx_commit |
| [02:47:04] | tgm4883: | took a mythfilldatabase from 70 minutes to 3 |
| [02:47:16] | Beirdo: | the buffer pool size makes a HUGE difference |
| [02:47:26] | tgm4883: | Beirdo, not in my testing |
| [02:48:43] | Beirdo: | it sure did for me |
| [02:48:47] | Beirdo: | and most others |
| [02:49:00] | Beirdo: | of course, I have my entire database as innodb |
| [02:49:21] | tgm4883: | Beirdo, maybe that makes a difference then |
| [02:49:27] | Beirdo: | relying on the mysql defaults is downright idiotic for innodb |
| [02:49:45] | tgm4883: | since most mythtv tables are created myisam |
| [02:49:47] | Beirdo: | using those settings as a baseline is a wise plan, and there may even be more to add |
| [02:50:10] | Beirdo: | not with MySQL 5.5 unless the create specifically says it |
| [02:50:50] | Beirdo: | and I'm not sure that we HAVE it specified |
| [02:51:40] | tgm4883: | Beirdo, IIRC, sphery said myisam was specified for everything |
| [02:51:58] | tgm4883: | Beirdo, everything but the temp tables, which was recently changed to specify it |
| [02:52:15] | Beirdo: | probably not on a dump/restore though |
| [02:52:30] | tgm4883: | Beirdo, wouldn't the dump say what type of table it is? |
| [02:52:39] | Beirdo: | not necessarily |
| [02:53:09] | Beirdo: | anyways, there's no harm in starting with those settings |
| [02:53:54] | Beirdo: | and mysqltuner.pl should be regarded as a prereq for using mysql |
| [02:54:10] | Beirdo: | we have too many ignorant users :) |
| [02:54:23] | Beirdo: | (note: ignorant, not necessarily stupid) |
| [02:54:35] | tgm4883: | Beirdo, which is why these settings aren't the best |
| [02:54:46] | Beirdo: | why? |
| [02:55:18] | Beirdo: | they are a way better baseline than defaults |
| [02:55:41] | tgm4883: | because setting innodb_flush_log_at_trx_commit to anything but 1 means it isn't ACID compliant, which if there is a power outage or OS crash, can cause DB corruption? |
| [02:55:45] | Beirdo: | from there, mysqltuner.pl can get you the rest of the way to non-suckage |
| [02:55:58] | Beirdo: | so? |
| [02:56:14] | Beirdo: | oh no, you lose some recording info. |
| [02:56:23] | tgm4883: | Sorry, I guess I just thought that database corruption would make users unhappy? |
| [02:56:33] | tgm4883: | yea, losing recording info kinda sucks |
| [02:56:40] | tgm4883: | scheduling data, probably not so much |
| [02:56:44] | Beirdo: | figuring most people are telling users to run with barriers off anyways, I don't see the difference :) |
| [02:57:03] | tgm4883: | Beirdo, we don't tell them to run with barriers off |
| [02:57:07] | Beirdo: | and if we were worried about ACID compliant, we would be using postgres |
| [02:57:08] | tgm4883: | we tell them to update |
| [02:57:33] | Beirdo: | historically, mysql used to be very sucky at ACID |
| [02:57:44] | Beirdo: | and we'd use transactions with commits too |
| [02:57:49] | Beirdo: | rather than auto-commit |
| [02:58:24] | tgm4883: | Beirdo, again, this is all fine and dandy for a mythtv database, which wouldn't have much lost data on a crash |
| [02:58:25] | Beirdo: | there's a long way to go with lots of things to fix before that happens, really :) |
| [02:58:33] | Beirdo: | right |
| [02:58:50] | tgm4883: | Beirdo, but as you put it, the users are ignorant, so they might have more than just mythtv as a database there |
| [02:58:56] | Beirdo: | and the wiki page says: |
| [02:58:57] | Beirdo: | # Customized config for MythTV baseline |
| [02:59:07] | tgm4883: | and those settings aren't database specific, they are system wide |
| [02:59:08] | Beirdo: | not "for general use" |
| [02:59:28] | Beirdo: | most people using mythtv have nothing else in their DB, I'd bet |
| [02:59:44] | Beirdo: | the only reason they use mysql is for mythtv |
| [02:59:52] | Beirdo: | (on that box) |
| [03:01:10] | Beirdo: | anyways, let's be realistiv |
| [03:01:14] | Beirdo: | realistic.. |
| [03:01:25] | Beirdo: | most users will never even look at the wiki |
| [03:01:28] | kc is now known as Guest48629 | |
| [03:01:32] | tgm4883: | Beirdo, true |
| [03:01:34] | Beirdo: | ignorant... and lazy :) |
| [03:01:42] | tgm4883: | Beirdo, which is why I want good settings in it |
| [03:02:11] | gary_buhrmaster1 (gary_buhrmaster1!~gtb@2001:470:80e4:3::36) has joined #mythtv | |
| [03:02:33] | tgm4883: | Because I have the power to make all new Mythbuntu users use those settings, which is why I want to make sure the settings are good defaults |
| [03:02:52] | Beirdo: | http://pastebin.com/zE8hQn05 |
| [03:02:52] | gary_buhrmaster1 (gary_buhrmaster1!~gtb@2001:470:80e4:3::36) has left #mythtv () | |
| [03:02:58] | Beirdo: | those are my innodb settings |
| [03:03:12] | Beirdo: | and I added a join_buffer_size = 2M too |
| [03:03:29] | tgm4883: | And I want good settings, if I was OK with just turning off all safe settings I would have done that already |
| [03:03:58] | Beirdo: | http://www.mysqlperformanceblog.com/2007/11/0 . . . tion-basics/ |
| [03:04:22] | tgm4883: | but since Guyverix does mysql stuff for his day job, I'll let him explain why these settings are good defaults |
| [03:04:29] | Beirdo: | we are NOT overly concerned about ACID |
| [03:04:44] | Beirdo: | read it for yourself at that URL :) |
| [03:04:53] | tgm4883: | Beirdo, actually, I've already read that |
| [03:05:52] | tgm4883: | I'll fully admit I'm not a mysql expert, which is why I got input from others the last time I did this testing |
| [03:05:54] | Beirdo: | losing a couple seconds worth of queries on crash really isn't that bad in most home use. |
| [03:08:27] | Beirdo: | if you want better than that, buy a UPS |
| [03:08:41] | tgm4883: | Beirdo, so I actually did a full backup/restore using the mythtv perl scripts within the last week. Out of 117 tables, all but 4 are myisam |
| [03:09:03] | Beirdo: | yes, all but mythweather (by default) |
| [03:09:15] | tgm4883: | record_tmp is innodb as well |
| [03:09:25] | Beirdo: | shouldn't be anymore |
| [03:09:42] | Beirdo: | that's a temp table that should be myisam from sphery's commit, no? |
| [03:09:50] | tgm4883: | IDK |
| [03:09:53] | tgm4883: | I would assume so |
| [03:10:00] | tgm4883: | I'm just reporting what phpmyadmin is telling me |
| [03:10:07] | Beirdo: | yeah, I hear ya |
| [03:10:19] | Beirdo: | I would expect that to be covered with his change |
| [03:10:38] | Beirdo: | mythweather's been that way for a long time, for reasons I forget now |
| [03:11:04] | Beirdo: | and if you ONLY have mythweather tables in innodb, the defaults might just work |
| [03:11:18] | tgm4883: | Beirdo, I have no problem making a change to the default settings. I just need to know its the right change |
| [03:11:57] | Beirdo: | this is why once we embed, the user and packagers will have no say in the settings :) |
| [03:12:00] | Beirdo: | heh |
| [03:12:06] | Beirdo: | anyways, I understand |
| [03:12:17] | tgm4883: | which is fine by me, I'll just send those users your way |
| [03:12:26] | Beirdo: | just saying though, I think those settings are a good baseline for a mythtv-only system |
| [03:12:59] | Beirdo: | once the database is embedded, the mysql engine is completely inside mythtv, and the application can tune the settings itself |
| [03:13:05] | Beirdo: | but that ain't yet |
| [03:13:33] | Beirdo: | you guys do a pretty good job, BTW. |
| [03:13:43] | Beirdo: | some other packagers tend to mess things up :) |
| [03:14:07] | Beirdo: | I'm glad you are concerned about getting it right. |
| [03:14:10] | Beirdo: | :) |
| [03:14:31] | tgm4883: | yea I don't like it when users complain about something I can fix |
| [03:14:46] | Beirdo: | knightr_: do you mean the complaints that the libraries are using PIC? |
| [03:14:53] | Beirdo: | makes sense |
| [03:15:36] | tgm4883: | well time to watch some TV, Guyverix ping me if you want to discuss it |
| [03:16:06] | Beirdo: | I'm gonna go out and have a late dinner, I think |

| [05:51:58] | Beirdo: | and I'm not in the mood to jump through stupid hoops because RedHat made a stupid decision |
| [05:52:32] | Beirdo: | system libraries for the currently running system belong in /usr/lib, not /usr/lib64 |
| [05:53:20] | Beirdo: | anyways, the user needed to update ld.so.conf :) |

| [10:16:03] | gnexus: | hello? |
| [10:17:07] | gnexus: | i'm working on mythtv on a new platform. |
| [10:17:13] | stoffel (stoffel!~quassel@pD9E43AB8.dip.t-dialin.net) has joined #mythtv | |
| [10:17:36] | gnexus: | i have one question only that needs to be asked |
| [10:17:52] | gnexus: | will anybody assist? |
| [10:18:51] | stuarta: | you haven't asked a question yet so how would we know if we could assist? |
| [10:19:23] | gnexus: | stuarta: currently my platform has no video accel |
| [10:19:31] | gnexus: | fb0 only. |
| [10:20:04] | gnexus: | i need fast simple way to have mythfrontend playback at VERY low res |
| [10:20:41] | gnexus: | like 320x240 |
| [10:21:01] | gnexus: | for testing... |
| [10:30:44] | gnexus: | nobody huh? |
| [10:31:40] | stuartm: | restrict the frontend to a 320x240 window? |
| [10:34:10] | gnexus: | stuartm: i can do that by command line now, but i need easy way to set that as a video mode in mythfrontend settings |
| [10:34:47] | gnexus: | i have little time to play with it, so it would help to have a fast procedure to do so |
| [10:35:18] | stuartm: | under Appearance settings, select 'seperate video modes for gui and TV playback' |
| [10:35:57] | stuartm: | there you can configure different output resolutions depending on the input res |
| [10:36:26] | stuartm: | or just the overall video output res |
| [10:37:17] | gnexus: | stuartm: thanks |
| [10:37:30] | stuartm: | or in theory you should be able to, doesn't seem to allow me to set any alternate resolutions here which is strange |
| [10:37:50] | stuartm: | it's not a feature which gets used much ... |
| [10:38:07] | gnexus: | how do i keep it from changing to res of the video being played? |
| [10:39:00] | gnexus: | for example myth window is 320 in menu, but then it changes to f/s for video |
| [10:39:04] | stuartm: | gnexus: it shouldn't be doing that, we scale to screen/output res, we don't change the screen res to match the video |
| [10:39:29] | gnexus: | interesting... |
| [10:40:09] | gnexus: | i'll keep playing with it a bit |
| [10:40:33] | stuartm: | gnexus: might be a setting for that, although I'm unsure, it might have been broken a while back and no-one noticed, again not a widely use feature or the great concern for MythTV since it's meant to be used fullscreen on a TV |
| [10:41:05] | stuartm: | it's not intended to be a windowed desktop app |
| [10:41:31] | gnexus: | i can understand that... |
| [10:41:40] | gnexus: | ;) |
| [10:42:00] | gnexus: | the current frame rate now in f/s is hopeless, but low/res vid in xine is fine |
| [10:42:21] | gnexus: | we are working on the vpu drivers for the platform |
| [10:42:33] | stuartm: | that doesn't mean work hasn't been done to allow it to run in a window, just that if that's been broken it's entirely possible that no-one has even noticed |
| [10:42:40] | gnexus: | other myth stuff on it is fine |
| [10:43:10] | gnexus: | window mode is fine for me until I play a vid |
| [10:43:37] | gnexus: | i've used it before long ago to play vids on lower-end systems |

| [14:59:00] | sphery: | Beirdo / tgm4883 : I haven't yet pushed the patch to change temp table usage (including the non-temp, temp table record_tmp) to specify MyISAM. Have it written, but wanted to test each individual usage before pushing. |
| [14:59:32] | sphery: | but, yeah, once pushed, all temp tables will use myisam... only one I've changed so far is mythfilldatabase's temp table for Schedules Direct users. |
| [15:00:34] | sphery: | and, fwiw, the backup/restore scripts will do backups that specify engine. Users who manually do mysqldump commands may not use the right command line and may not get it (in which case they will also corrupt parts of their DB due to losing other mysql-specific features we rely on) |

| [16:34:48] | Beirdo: | I'd really want that back in for release, so I was trying to determine what was borking, and I can't reproduce it... likely timing-related then |

| [16:39:53] | stuartm: | yeah, seems there's no full bt in the log, just that thread so I'd need to revert locally to repro – just let me know |
| [16:40:25] | Beirdo: | if you get a spare moment at some point, would be cool |
| [16:40:39] | Beirdo: | certainly not highest priority. |
| [16:41:56] | Beirdo: | I think that mutex lock should have a much smaller scope in LogPrintLine |
| [16:42:20] | Beirdo: | I forget why it got changed to be the entire function. Maybe danielk remembers :) |
| [16:42:37] | Beirdo: | it's only supposed to be to protect the queue |

| [16:50:53] | stuartm: | will do |
| [16:54:38] | Beirdo: | as that locks the mutex, then the LOG() in the ctor does... I could see that being an issue |
| [16:55:07] | Beirdo: | again, not sure why I had it locking the queue around creating the thread when the thread itself handles the lock just fine |
| [16:56:54] | stuartm: | git blame reveal anything, or was that history lost in the refactor? |
| [16:56:57] | Beirdo: | the only thing it possibly would affect would be in the ctor itself, hence the possible deadlock. |
| [16:57:20] | Beirdo: | it showed it being me from one of the initial checkins of the logging |
| [16:57:37] | Beirdo: | well, split logging (i.e. zeromq) |

| [18:22:18] | skd5aner: | danielk22: Google had a interesting solution to the leap second issue. They essentially added a few milliseconds to their NTP servers over the entire day the leap second was added. So, by the time the leap second hit, it synced to the time that had been "slowed" down – http://googleblog.blogspot.com/2011/09/time-t . . . seconds.html |
| [18:23:27] | Beirdo: | I think maybe ntpd should be changed to do that, although that does require programmatic access to leap second info ahead of time... and causes unsynced clocks world-wide for a day |
| [18:23:58] | Beirdo: | better to just actually deal with it properly, I guess. |
| [18:24:06] | Beirdo: | i.e. not go apeshit |
| [18:25:31] | skd5aner: | yea – seems like a pretty nice way of dealing wth it – although I'm sure some systems out there wouldn't necessarily like such a thing – like trading platforms |
| [18:25:43] | Beirdo: | or VOIP |
| [18:25:50] | Beirdo: | or streaming video |
| [18:28:03] | danielk22: | Beirdo: skd5aner: The google hack requires everybody syncing to the same time server. Workable at google, but to scale worldwide the hack would need to be made inside the ntp client on each machine. |
| [18:30:32] | stuartm: | or just drop the whole notion of leap seconds as it relates to computers, it's a distinction that really doesn't matter a great deal outside scientific circles |
| [18:30:58] | Beirdo: | danielk22: yeah, that's the big issue :) |
| [18:31:12] | Beirdo: | stuartm: drop leap days too for that matter |

| [18:35:44] | danielk22: | I'm sure someone will make a tutorial on how to test software for leap seconds.. This affected enough systems that things like the Linux kernel will be tested ahead of time in the future. |
| [18:35:48] | stuartm: | heh |
| [18:36:03] | Beirdo: | yeah, I expect this won't reoccur. |

| [18:36:57] | stuartm: | Beirdo: it was probably fixed by your changes, I'm not sure what version I was running at the time, but simply changing the timezone on a running machine was enough to cause multiple mythlogserver processes to be spawned |

| [18:47:26] | stuartm: | oh, right on the mythweb repo |
| [18:47:51] | stuartm: | that's not the least bit confusing, why don't we move it back under the one repo? |
| [18:47:56] | Beirdo: | yeah, we should probably add that to the release script. I missed it on 0.24.3 too |
| [18:48:20] | Beirdo: | well, that was for ease of packaging et. al, I think |
| [18:48:37] | Beirdo: | xris and kormoc would be the ones to know more details on the why :) |
| [18:48:52] | stuartm: | hmm, not sure how it makes packaging easier given that most distros split out the plugins into individual packages anyway |
| [18:49:32] | Beirdo: | well, I don't do packaging, personally, so I dunno. I'd think one repo would work well, but what do I know? :) |
| [18:50:50] | xris: | stuartm: mostly because rpm sucks (dunno about deb). can't make a .noarch package from teh same repo as a .x86_64 one |
| [18:50:55] | xris: | er, spec |
| [18:51:41] | skd5aner: | danielk22: I don't think so... I mean, there's been something like 25 leap seconds added since 1970... so why is it that so many things were impacted the 25'th go around? |
| [18:51:44] | xris: | but that's something that can be worked around.. it's mostly that mythweb should theoretically track independently of the backend, now that the bindings are developed separately |
| [18:51:47] | stuartm: | fwiw I'm thinking of proposing that we drop the unmaintained plugins, move them into a separate repo maybe (like themes) or at the very least make it clear that they aren't 'official' any more |
| [18:52:14] | stuartm: | I think it's better for users to understand what's being actively maintained and what isn't e.g. mytharchive, mythzoneminder and possibly others like mythgame |
| [18:52:58] | stuartm: | maybe that would go hand in hand with improvements to the plugin API to encourage more third party plugin development and maintenance |

| [18:58:51] | danielk22: | Beirdo: That hasn't been confirmed, but that's what it looks like ATM. |
| [18:59:07] | Beirdo: | sounds reasonable |
| [18:59:33] | Beirdo: | stuartm: yeah, we should look into de-crufting the plugins. Sounds like a task for 0.27, maybe :) |

| [19:01:15] | Beirdo: | well, at least now I'm fairly satisfied that logging is sane again (other than the dblogging flapping, didn't get to it this weekend) |

| [19:04:58] | MythBuild: | Hey! build master-linux-ppc #2715 is complete: Success [3build successful] |

| [19:08:22] | skd5aner: | danielk22: yea – I guess my point was that if they've had 25 chances to learn from, I have little faith that things won't break the 26'th go around ;) |

| [19:12:39] | danielk22: | skd5aner: There has only been one other leap second in the last 7 years, two in the last 12.. |
| [19:14:16] | sphery: | fwiw, some of my systems had issues last time (kernel panic). this time, not a single system got affected at all--they all worked... so it was just a new bug added to newer versions--meaning it can be done right, but like all things with very little testing... |
| [19:14:46] | sphery: | no huge cpu or reboots required or resetting time required or ... |
| [19:19:59] | Beirdo: | heh |
| [19:20:30] | Beirdo: | lucky guy. I only had 200% CPU for each of mythbackend, mythlogserver, mysql |
| [19:20:56] | sphery: | yeah, seems my laziness paid off (still running an old kernel :) |

| [19:21:05] | Beirdo: | oh, and mythfrontend on the other box |
| [19:21:34] | Beirdo: | my kernels are about 2 years old, not exactly new |
| [19:22:04] | Beirdo: | and it sounds more like a glibc/eglibc issue than a kernel one maybe this time. Dunno |
| [19:22:45] | sphery: | ah, then my old glibc :) (or the fact that I'm actually using glibc instead of eglibc--I don't fear the Drepper) |
| [19:23:10] | Beirdo: | heh, that could be a contributing factor, yeah |
| [19:23:22] | Beirdo: | didn't hear of too many kernel panics this time |

| [19:47:12] | stuartm: | yeah, no reports of panics, just very high loads on certain processes |
| [19:48:44] | stuartm: | or dozens of certain logging applications spawned (two every 5 seconds for 8 hours) until the machine is all the way into swapped, maxed out and unresponsive |
| [19:50:46] | stuartm: | did this only affect machines running ntpd? |
| [19:51:02] | stuartm: | (client) |
| [20:04:38] | Beirdo: | I think so |
| [20:05:02] | Beirdo: | you only got 2 per 5s? |
| [20:05:17] | Beirdo: | nice. I got about 100 per 5s spam-launching |
| [20:05:38] | Beirdo: | which is protected against now too as a result |

| [20:23:23] | stuartm: | Beirdo: tbh I assumed 2, one for mythbackend and one for the frontend, but it could have been more, I didn't look too closely at the time since I was more preoccupied with making it stop ;) |

| [20:24:54] | stuartm: | I got about a dozen processes spawned when I corrected the timezone after a reboot, I don't know if that's indicative of the number of processes it was spawning every 5 seconds after the leap second |
