| 00:00 | <kormoc> | GreyFoxx, ooh, I've wanted to ask you a question about dvd playback. My box's playback is weird, jumpy video and audio. Have any suggestions on debug channels to use to figure out why? |
| 00:03 | <GreyFoxx> | I find -v playback to be most useful |

| 00:04 | <kormoc> | kk, I'm assuming it's related to being a sata dvd player, but yeah, it'd be nice to know |
| 00:06 | -!- | jhulst [n=jhulst@unaffiliated/jhulst] has joined #mythtv |
| 00:06 | <GreyFoxx> | don't think I've even seen a sata dvd drive yet :) |
| 00:07 | <kormoc> | Heh, I ordered the wrong one accidentally so I'm sorta stuck with it. |
| 00:10 | * | GreyFoxx downgrades all frontends to 16431 |
| 00:13 | <clever> | ticket #4896 opened |
| 00:14 | <clever> | looks like a real simple fix and solve the problem i had |
| 00:14 | <Anduin> | They are nice when you only have one PATA header, I haven't seen any sata related problems with mine. |
| 00:18 | <Anduin> | Why is extracting out the channel changers a good idea? I know I read something in the scrollback. |
| 00:20 | <kormoc> | Anduin, less binary blobs for svn to deal with |
| 00:20 | <kormoc> | Anduin, also real diffs on updates and the like |
| 00:21 | <kormoc> | Anduin, was there any specific reason not to? |
| 00:21 | <Anduin> | It breaks my rpm build... so no :) |
| 00:21 | <kormoc> | Heh, sorry |

| 01:32 | <hads> | kormoc: That does seem like an odd commit message. |
| 01:32 | <kormoc> | Which one? |
| 01:33 | <hads> | Sorry, relating to that post on -dev list about r16471 |
| 01:34 | <kormoc> | It's true, isn't it? |
| 01:34 | <Chutt> | no? |
| 01:34 | <kormoc> | Oh, whoops, I'll add them back in then |
| 01:34 | <Chutt> | i mean, the backend _should_ run it |
| 01:34 | <Chutt> | but there's no reason it has to |
| 01:35 | <hads> | Obviously people can run from if they want to, just sounded odd. |
| 01:35 | <hads> | Loads of people here still use the --file option from cron I believe. |
| 01:35 | <kormoc> | Ahh, I thought there was some technical reason we wanted the backend to do so, my mistake |
| 01:35 | <Chutt> | naw |
| 01:35 | <Chutt> | the only real thing is the scheduling, but that's not strictly necessary |
| 01:36 | <kormoc> | Gotcha |
| 01:41 | <hads> | The --capabilites stuff allows us to let the backend to do it now normally though which is great. |

| 05:20 | <cesman> | is there a reason MythWeather uses innodb instead of myisam? |
| 05:20 | <clever> | something about something keys |
| 05:23 | <hads> | Foreign |
| 05:26 | <kormoc> | Aye, it uses constraints to handle the deletion and the like |
| 05:30 | <cesman> | kormoc: is that an answer to my question? |
| 05:30 | <hads> | Yes |
| 05:30 | <cesman> | ok |
| 05:30 | <cesman> | thanks |
| 05:31 | <hads> | Foreign key constraints and other good stuff are only supported in the InnoDB engine in Mysql. |

| 07:22 | <gbee> | I don't think 16471 is a bad idea, plenty of users still think mythfilldatabase has to be run via cron script or with custom args but that's not the case |
| 07:26 | <rooaus> | gbee: Wasn't part of mythfilldatabse moved into the housekeeper thread so it doesn't need to be run when using EIT only etc? I thought that was why those scripts existed? |
| 07:27 | <gbee> | the cleanup of the program table was moved to the housekeeper, yes |
| 07:28 | -!- | phatmonke [n=ben@81.2.121.150] has quit [] |
| 07:28 | <gbee> | I'm not sure why those scripts exist, I think you've mentioned the only good reason and that no longer applies |
| 07:29 | <gbee> | the scripts and custom args field in mythtv-setup are more likely to do harm than good, xmltv now picks the best options for that grabber automatically, user supplied args are probably inefficient or incorrect |

| 08:21 | <sphery> | gbee: Yeah, but now we have scripts like contrib/smartfill (moved to contrib/mythfilldatabase/smartfill ), which--by its name alone--tells users it's better than what's in Myth. And it's "better" because it always downloads +7, this next Sat and Sunday, and today as well as +1 and +13... So, rather than the bandwidth/resource friendly SchedulesDirect usage of +1 and +13, it downloads 6 days of data every day... |
| 08:21 | <sphery> | Give users a flexible tool and they'll figure out how to abuse it. |
| 08:22 | * | sphery would like to see smartfill get removed, too |
| 08:22 | <laga> | gbee: i use --update. although i should configure my grabber correctly :) |
| 08:22 | <gbee> | yup |
| 08:29 | <akv> | ain't it a problem that backend and frontend has to be exactly same versions? Of cause it works fine with one box running both backend and frontend...but several boxes with frontend, some on laptops that are running different distros... ? |
| 08:31 | <laga> | build it yourself? |
| 08:31 | <akv> | laga: gonna be a pain to maintain... |
| 08:32 | <laga> | well, running different distros sounds like a pain to maintain, too :) |
| 08:32 | <laga> | i'd expect that most big distros will have builds of 0.21 available soon |
| 08:32 | <akv> | laga: well...i'd like to run something stable on my server but testing on my laotop |
| 08:32 | <akv> | laptop |
| 08:32 | <laga> | and different revisions from the fixes branch tend to be compatible |
| 08:33 | <laga> | akv: so you want to run trunk on your laptop and 0.21/0.20 on your server? |
| 08:33 | <akv> | something like that |
| 08:34 | <akv> | at the moment...it's not a problem cause i'm running ubuntu hardy on the server |
| 08:34 | <akv> | but when it goes stable, i'm not going to upgrade the server |
| 08:35 | <laga> | akv: that's not possible. development tends to break things, including backwards compatibility. |
| 08:35 | <laga> | akv: mythbuntu usually has trunk builds |
| 08:36 | <akv> | ain't it possible to allow the newer backend to negotiate with the backend of which functions are available somehow to have full backwards compatibility? |
| 08:37 | <laga> | probably, if you submit a patch ;) |
| 08:37 | <akv> | auch! ;) |
| 08:37 | * | akv felt a slap there ;) |

| 14:41 | <sphery> | Yeah. Too bad I tend to keep all my favorite shows to watch in a marathon... |

| 14:48 | <sphery> | kormoc: And here I though MrGandalf's patch on #4599 was a good one to replace myth.find_orphans.pl /and/ myth_archive_job.pl (allowing us to delete 2 from the repo) because Mark's at least uses the Perl bindings somewhat (for Storage Groups, at least). I guess, though, it could probably get all the DB connection info from the bindings, too. |
| 14:50 | <sphery> | OK, now that I look at it, it seems to get the recordings list and the DB connection using the bindings... |
| 14:54 | <kormoc> | I might just be blind, perl isn't my best language |
| 14:55 | <sphery> | I did just write some scripts using the perl bindings, so I had a head start... :) |
| 14:56 | <sphery> | the "use MythTV;" and the "my $MYTH" stuff... |
| 14:56 | <kormoc> | Well, I thought there was methods to do what sub getRecordings is doing |
| 14:56 | <kormoc> | same with getStorageGroups |

| 15:00 | <kormoc> | Yeah, get_recording_dirs should replace getStorageGroups, tho, it should likely be updated to the style he uses (get the name as well as the dir) |
| 15:03 | <kormoc> | and shouldn't getRecordings use the recordings object/class rather then using the array, no? |
| 15:03 | <sphery> | Agreed on both points. |

| 15:04 | <kormoc> | kk, so I wasn't too far off, I'll comment a bit more detailed as to what I mean |
| 15:05 | <sphery> | Though, get_recording_dirs (in the bindings) needs updated to use the new StorageGroup::getRecordingsGroups() (meaning a change to the protocol to expose that info) |
| 15:05 | <sphery> | I'll put that one on my TODO list... |
| 15:05 | <sphery> | That allows us to differentiate between, i.e. DB Backups or Thumbnails storage groups or those that will be used with plugins, such as MythVideo. |
| 15:07 | <sphery> | kormoc: What do you think of the idea of removing myth.find_orphans.pl and myth_archive_job.pl? |
| 15:07 | <sphery> | (once that one is committed) |
| 15:07 | <kormoc> | I'm quite in favor of it |
| 15:07 | <sphery> | Cool. I really want to clean up some of the old legacy scripts from contrib (so was glad to see your reorganizing it). |
| 15:08 | <sphery> | If we do it soon after 0.21 is released, anyone who feels the new script is missing functionality provided by the just-replaced scripts has plenty of time to fix it, too. |
| 15:09 | * | kormoc nods |

| 16:18 | <kormoc> | #4872 |
| 16:18 | <gbee> | not tried the latest patch, earlier versions used the Full zoom on content that was better Half zoomed, but I think he sorted that |
| 16:19 | <gbee> | GreyFoxx: so DVD playback is broken in 0.21? :( |
| 16:20 | <GreyFoxx> | gbee: Yeah so far all DVD's Ive tried in multiple frontends under multiple resolutions crash the FE |
| 16:20 | <GreyFoxx> | 16434 the video alignment change seems to be the culprit |
| 16:20 | <gbee> | think that would probably deserve a 0.21a release once fixed |
| 16:20 | <GreyFoxx> | I think so |
| 16:20 | <gbee> | danielk22: you aware of this? |
| 16:20 | <kormoc> | hrm |
| 16:21 | <kormoc> | would it be broken in trunk as well? |
| 16:21 | <GreyFoxx> | Not sure about trunk, I haven't switched back to it yet |
| 16:21 | <laga> | GreyFoxx: i don't even get video playback when i try to play a dvd iso. audio works, though |
| 16:21 | <gbee> | kormoc: if the change was merge from fixes |
| 16:21 | <GreyFoxx> | laga: I think the DVD iso is the same issue |
| 16:21 | <GreyFoxx> | try reverting to 16433 and see if it plays |
| 16:22 | <laga> | GreyFoxx: i'll try later, i'm struggling with python at the moment |
| 16:22 | <gbee> | DVD playback has been very reliable in trunk, so any issues are probably related and recent |
| 16:22 | <laga> | ah, there's a ticket already for dvd iso.. |
| 16:22 | <kormoc> | Cause I'm having an issue with it crashing on chapter changes, but it starts playing fine |
| 16:23 | <GreyFoxx> | I had to resort to mplayer last night to watch a dvd |
| 16:23 | <kormoc> | my dvd stuff always seems to be weird |
| 16:23 | <GreyFoxx> | hehe I wouldnt have minded if I wasn't showing off the stuff to a friend who had come over :) |
| 16:23 | <GreyFoxx> | after he left I went digging to find out where it broke heh |
| 16:23 | <kormoc> | That's how it always works :P |
| 16:23 | <GreyFoxx> | yeah :) |
| 16:23 | <laga> | the internal player for dvds has never worked well for me :/ |
| 16:23 | <stuarta> | evening all |
| 16:23 | <GreyFoxx> | this is the first dvd playback I've had in a long while |
| 16:23 | <gbee> | hmm, actually I've just tried, and a second DVD crashed on an assert in vm.c - that's never happend before |
| 16:24 | <GreyFoxx> | 16434 buffer size/alignment change is leading ffmpeg to write data outside of our allocated buffer I believe |
| 16:24 | <gbee> | I wrote off the first assert crash as being specific to the DVD, but two in a row? |
| 16:25 | <gbee> | right, a known working DVD refuses to play ... |
| 16:25 | <gbee> | starting to suspect one of the changes made by Erik's patches to libdvdnav |
| 16:26 | <GreyFoxx> | We should define a set of |
| 16:26 | <gbee> | either that, or my drive has gone on the fritz |
| 16:26 | <GreyFoxx> | oops wrong channel :) |
| 16:27 | <gbee> | err PEBCAK |
| 16:28 | <gbee> | forgot that I formatted and reinstalled late last week, so I no longer have decss installed ... |
| 16:28 | <gbee> | doh |
| 16:30 | <stuarta> | doh indeed |
| 16:30 | * | stuarta notices we've done a release <- been away for the weekend |
| 16:31 | <danielk22> | gbee, maybe this is a good opportunity to fix some segfaults when decss isn't installed.. |
| 16:32 | <gbee> | danielk22: yeah |
| 16:34 | <gbee> | not a high priority issue though, the regression in DVD playback caused by 16434 is more important right now |
| 16:35 | <gbee> | wish I could help with that :/ |
| 16:35 | <danielk22> | gbee: What is the regression? Is there a ticket? |
| 16:36 | <GreyFoxx> | dvd playback crashes for me on all frontends, multiple disk, multiple resolutions |
| 16:36 | <GreyFoxx> | I put a backtrace on a ticket |
| 16:36 | <GreyFoxx> | looking for the number now |
| 16:36 | <gbee> | several reports, at least one on the -user list |
| 16:36 | <GreyFoxx> | 4897 |
| 16:36 | <gbee> | #4898 |
| 16:36 | <danielk22> | any usable backtraces? |
| 16:36 | <GreyFoxx> | I put a bt on there, but I can certainly make another |
| 16:37 | <GreyFoxx> | reverting to anything before 16434 plays fine |
| 16:39 | <danielk22> | hmm, looks like one is with the intel drivers the other with via.. I'm guessing both have a XVideo layout unlike the nvidia.. |
| 16:40 | <GreyFoxx> | the two FE's I've had crashing are Nvidia |

| 16:49 | <danielk22> | yeah, it's the same. ffmpeg is writing outside the bounds of the allocated frame it seems. Actually the -v playback log might be more useful than the backtraces.. |

| 18:20 | <gbee> | I was suggesting earlier that we push out a 0.21a release, but that depends on Chutt having the time/motivation |
| 18:20 | <Chutt> | naw, not for just dvd |
| 18:20 | <Chutt> | two weeks, then i'll consider a point release |
| 18:21 | <gbee> | how serious it is all depends how many DVDs you watch I guess ;) |
| 18:21 | <danielk22> | gbee, chutt: I've attached a better fix to #4897. Testing with a few DVD's now.. |
| 18:22 | <Chutt> | i don't consider it a huge problem :p |
| 18:23 | <gbee> | superm1: this a patch you can apply to the packages going through for Hardy? |
| 18:23 | <danielk22> | chutt: This bug might also break playback in Australia, where aspect only stream changes can happen. I don't know it will for a fact though. Still we might want to wait a little while to see if any other problems turn up.. |
| 18:23 | <Chutt> | right |
| 18:23 | <Chutt> | no point putting something out now, and then again a few days later |
| 18:23 | <Chutt> | fixes branch is good enough, most packagers pull from that anyway |
| 18:24 | <danielk22> | chutt: is trunk fully synced from fixes now? |
| 18:24 | <Chutt> | um |
| 18:25 | <Chutt> | i may be a tad behind |
| 18:25 | <Chutt> | i last synced it friday night |
| 18:25 | <janneg> | danielk22: aspect only stream changes are also common in europe. I haven't noticed any problems though |
| 18:25 | <gbee> | danielk22: no, I know there is at least one of mine which hasn't yet been synced, it's a minor plugin patch though |
| 18:25 | <Chutt> | danielk22, aspect only changes should still send the same w/h, though |
| 18:25 | <Chutt> | so it should be fine |
| 18:25 | <danielk22> | janne, ok.. i wasn't sure if it would be a problem depends on whether w&h are sent.. |

| 18:45 | <danielk22> | k, thx |
| 18:45 | <Chutt> | buttons won't work on chromakey, i don't think |
| 18:45 | <rooaus> | kormoc: Updated #3664, wasn't able to test as I don't have the problem file any more. What do you think fixed it? |
| 18:45 | <Chutt> | ie, dvd buttons/overlays/etc are the reason there's the ai44 subpicture support in xvmc |
| 18:46 | <kormoc> | rooaus, it uses the perl bindings and they should handle the failures gracefully now I believe |
| 18:47 | <kormoc> | And if not, it should be fixed in the bindings to do so |
| 18:50 | <rooaus> | kormoc: OK, I think the prob may still exist but the patch was the only perl I have ever written. Will consider the binding fix if I can reproduce it. |
| 18:51 | <kormoc> | Sounds good, could always ping xris too if it's a complicated chunk of code |
| 18:51 | <gbee> | hmm, X is currently using 33% memory on a 2Gb system during playback of a DVD |
| 18:51 | <danielk22> | chutt: the dvd menu stuff is done in the NVP, and without enough info on the size of the OSD surface.. so if there is any zooming, or you use a renderer that renders the OSD at a different resolution, like PVR-350, XvMC-OpenGL, OpenGL, chromakey, etc the highlights are in the wrong place... |

| 19:25 | <rooaus> | gbee: What do you think about adding storage group support to mythmusic? |
| 19:26 | <gbee> | rooaus: like the idea, is it an offer, or a suggestion? :D |
| 19:26 | <gbee> | wouldn't be hard to implement |
| 19:27 | <rooaus> | gbee: Offer (if I can), you had mentioned upnp but storage groups would work better for offline storage (ipods, usb etc) |
| 19:28 | <gbee> | rooaus: I was considering re-using upnp with music stored on the backend and shared between frontends, but only because upnp is available and perfect for the job |
| 19:31 | <rooaus> | gbee: Fair enough. The more I look at storage groups the more I like them, does seem to be a rather nifty concept and works well in a myth context. |
| 19:31 | <gbee> | I don't think it prevents us from using storage groups, i.e. your main collection is stored on the backend under a backend storage group but the frontend can still work from local (portable) storage devices connected directly |
| 19:34 | <gbee> | If I ever do get around to moving stored media to the backend, music and video, then it won't be before 0.23, mythui and other things will probably keep me busy for 0.22 |
| 19:35 | <gbee> | by that time someone else will probably have supplied a patch, that usually happens with all my best ideas, someone else implements them before I have a chance ;) |
| 19:38 | <rooaus> | Yeah, I know you had plans for mythmusic, I just wanted to confirm that this fitted in with them. There is already some work being done on moving the video stuff to storage groups, not sure where that is at though. |
| 19:41 | <gbee> | I've drifted away from mythmusic because many of the changes I wanted to make will be easier and better under mythui, so I'll be working on that first |
| 19:42 | <gbee> | then the metadata restructuring (because I've started it, so I might as well finish) |
| 19:42 | <gbee> | and after that I'll probably re-write my playlist editor patch for mythui |

| 19:49 | <gbee> | eskil's shoutcast patch frightens me, it's not that I don't like the idea but merging it means touching the music tree and I really don't like that, it gives me headaches :) |

| 19:51 | <gbee> | I think Paul has a better grasp of the playlist/music tree code and I respect him for that, he's probably in a better position to review and commit the patch than I am |
| 19:52 | <sphery> | rooaus / kormoc : responded with some more background on #3664 on the -dev list . It should be fixed but for a very different reason... ;) |
| 19:52 | -!- | siXy2 [i=siXy@88.211.54.195] has quit [Client Quit] |
| 19:52 | <rooaus> | gbee: Yeah the music tree stuff is fun ;) |
| 19:52 | <kormoc> | Kk, I'll take a gander |
| 19:54 | <sphery> | gbee: I love the idea of backend storage/UPnP delivery of Music (and Videos). I hope someone writes a patch and steals credit for your idea. (And, even in that approach it should be using a "special" storage group--see StorageGroup::kSpecialGroups). |
| 19:54 | <kormoc> | I really want videos streaming from the backend so we can use the flash video player to play them too :) |
| 19:55 | <gbee> | hey, I don't mind them taking credit, I just look forward to writing the code and I'm disappointed when I don't get the chance |
| 19:56 | <sphery> | my backends can't even play my recordings in real time, let alone transcode them... :( |
| 19:58 | <rooaus> | sphery: Agree about the special group, that was the plan... and maybe one for ripping as well (which is implicitly part of playback group). |
| 19:58 | <sphery> | rooaus: sounds good. |
| 19:58 | <gbee> | then there are the purely selfish times when the changes others propose go in different direction from what I personally wanted to do, hard to argue that someone else contribution shouldn't be include merely because it's not what I had in mind or because I don't really want to maintain it |
| 19:59 | <gbee> | s/else/elses/ |
| 20:01 | <rooaus> | gbee: That is understandable, people can submit patches then disappear to never maintain/help with code once in svn. |
| 20:01 | <sphery> | I'll be putting support in the protocol for getting access to StorageGroup::getRecordingsGroups(), so we can leave those special groups out of, i.e. MythWeb's create-a-new-recording-rule page. I'll also be modifying the backend status page so they're shown in separate Disk Usage sections, but I'm waiting on gnassus's MythVideo storage groups changes (which should add some sort of storage group type). |
| 20:01 | <xris> | cool |
| 20:02 | * | xris still wants a "get listings" query... |
| 20:02 | <xris> | I think cdev put one into the xml queries, though. I just need to use it. |
| 20:03 | <sphery> | That sounds like a good approach--use the protocol for those things the frontends need, but use UPnP for "extra" info... |
| 20:03 | <sphery> | s/UPnP/MythXML/ |
| 20:03 | <rooaus> | sphery: Thanks for the detail on #3664, clears that up. |
| 20:05 | <sphery> | I happened to remember that changeset quite well, as I had been applying a hack patch for a couple of years to disable the load_file_info because it killed my backends (doing 5 "views" of links for 400+ recordings every 30 minutes--it couldn't complete one view in the 30 minutes... :) |
| 20:06 | <sphery> | When I mentioned it to xris, he said something to the effect of, "Oh, we're still doing that? It's been long enough we should be able to trust file extensions," and committed a change soon after. |
| 20:08 | <xris> | sphery: personally I think that the API should have both mythproto and xml versions of everything. there should be a mythapi object that has proto and xml input/output methods |
| 20:09 | <sphery> | Well, that clears up my question... Was just considering whether it made more sense to expose StorageGroup::getRecordingsGroups() info via XML or myth proto. |
| 20:09 | <xris> | my main interest is to get as much stuff as possible away from raw db queries. There's no reason that mythweb/perl needs to talk to the db -- it would be far more efficient for the backend to maintain the info in RAM and just pass it back upon request. No need to join tables, etc, etc. |
| 20:10 | <xris> | but I don't have much control over the c++ code (esp. because I, well, can't do c++)... so all I can do in that venue is recommend that it's a good architectural idea. |
| 20:10 | <sphery> | We really don't have a listings equivalent of ProgramInfo, do we? |
| 20:12 | <sphery> | If we did, I'd definitely volunteer to add it to the proto for you. Since we don't, I'll say that if you can get me a good idea of what info/format you want, I can put it on my list... |
| 20:13 | <sphery> | I'm thinking, though, that sending a long list of ProgramInfo::ToStringList() might be a bit heavy... |
| 20:13 | <sphery> | especially on some of these boxes with hundreds or thousands of channels... |
| 20:14 | <xris> | yeah, that was my concern. |
| 20:14 | <xris> | I think a request by channel and start/end time range would be usable. |
| 20:14 | <sphery> | Still just dumping a bunch of ProgramInfo's? |
| 20:14 | <xris> | could make it start/end and list of chanids |
| 20:15 | <gbee> | ProgramInfo::ToStringList() is probably overkill for listings data, but maybe we should start by listing what data we'd expect |
| 20:15 | <xris> | same format that the upcoming/recorded program queries work now |
| 20:15 | <xris> | s/work/use/ |
| 20:15 | <sphery> | that's ProgramInfo::ToStringList() |
| 20:15 | <gbee> | right, that's pginfo tostringlist |
| 20:16 | <gbee> | I'm thinking that for listings you just need, title, subtitle, genre and time |
| 20:16 | <sphery> | (my copy/paste was faster :) I'll see about coding it up and let you play with the patch... If usable, I can submit it for review. |
| 20:17 | <gbee> | the rest can be grabbed as requested, one at a time from the backend |
| 20:17 | <sphery> | Maybe a ProgramInfo::ToStringListLite() ;) |

| 20:18 | <rooaus> | ^^^ Now with 50% less text |
| 20:18 | <rooaus> | :) |
| 20:18 | <gbee> | sphery: I'm only guessing that it would be faster and lighten the load on the server, I'd be interested to see the actual benchmarks of a Lite() version |
| 20:19 | <sphery> | xris: If I can clear a few other things off my list, I'm hoping to work on the recordedfile info, too (though perhaps with heavier data stored or potentially stored in the DB, too) |
| 20:19 | <gbee> | the bulk of a ToStringList is the text and that would be included in any Lite() version anyway |
| 20:19 | <sphery> | gbee: d'oh... benchmarks = do both approaches and profile = do twice the work plus a profile :) |

| 20:20 | <xris> | I need to find some time to do more work on mythweb stuff, but I'm hoping that by the time I do, SD will be ready to start our self-hosting project, which will then eat up all of my free time again. |
| 20:21 | <sphery> | xris: That's OK. kormoc has been a good xris double. (But we have missed you :) |
| 20:21 | <gbee> | sphery: I'd just benchmark against what we've got now :) But yes, it would be more work and that's why I was careful not to say you should actually do it |
| 20:21 | <kormoc> | Heh |
| 20:22 | <xris> | sphery: yeah. that's why I hired him. :) |
| 20:22 | <sphery> | Actually, an interesting programming task is always worthwhile, even if you throw the code away. I enjoyed hacking a shell-based backup script, which I'm now planning to throw away and use a Perl-based one I wrote. |
| 20:22 | <xris> | both in real life, and for mythweb. :) |
| 20:22 | <kormoc> | amazingly enough, I really need to do a bit of low level php profiling with how we deal with protodata, it can take upwards of 80% of my execution time for certain strings to get worked out |
| 20:22 | <rooaus> | xris: An autoexpire manager/listing would be real cool in mythweb, seems a good interface for reviewing large lists of data. But sadly, my dog ate my patch :D |
| 20:22 | * | kormoc laughs |
| 20:22 | <kormoc> | I keep meaning to do that one of these days (tm)(r) |
| 20:23 | <xris> | kormoc: yeah. we could *definitely* improve the performance of mythproto by treating the strings as files and doing some binary-file read/write techniques rather than just using split() on the strings. |
| 20:23 | <kormoc> | Xris has been bugging me for about three and a half years to redo the video interface, and that's sorta mostly done |
| 20:24 | <gbee> | on a related matter, it's been a while since anyone did some profiling/benchmarks of the queries we are using |
| 20:24 | <sphery> | kormoc: would you consider a patch to MythWeb that defered loading of the recording details in the listings page until the mouse hovers over a link for a bit (0.25 seconds or so?) I feel guilty moving my mouse cursor off the listings window because of how many links I cross... |
| 20:25 | <sphery> | gbee: and now they can be profiled against MySQL 5 versions of the queries... :) |
| 20:25 | <kormoc> | sphery, Sure, I actually don't quite like the instant hit as well, but I didn't want to be the only one who felt that way :) |
| 20:25 | <kormoc> | sub-queries rock! |
| 20:25 | <gbee> | sphery: trust you to see where I was going with that ;) |
| 20:26 | <sphery> | kormoc: If I can figure it out enough, I'll try to code one up. That way, you'll have my name on the ticket/patch to defer blame... |
| 20:26 | <gbee> | here I go again, proposing more work even before I've finished the last lot ;) |
| 20:27 | <sphery> | we're afraid to let you run out of work as you might find other (non-Myth) things to do and we don't want to lose you. |
| 20:28 | <gbee> | sphery: you've given me a great idea, from now on I'll submit all my work as patches under a pseudonym - "It wasn't me guv, 'onest. It was Bob666!" |
| 20:29 | <sphery> | lol, |
| 20:29 | <sphery> | Hmmm. Have you noticed that all gbee does anymore is review patches from Bob666? |
| 20:31 | <gbee> | could develop into a split personality where I start rejecting my own patches because they aren't good enough .... |
| 20:32 | <gbee> | I don't have time to seek professional mental help, so I think I'll stick to the way things are now ;) |
