| evand | cjwatson: obviously not for karmic, but does something like http://pastebin.ubuntu.com/300153/ seem reasonable to handle IO errors occurring outside of the file copy routine that are not handled (such as in bug 445681)? | 00:40 |

| evand | that is, simply moving the EnvironmentError exception handler one level higher | 00:41 |
| cjwatson | ENOENT might be a bit too general at that level, and quite possibly ENOTDIR too, but the others would be OK to move up like that, I think | 00:47 |
| evand | okay, thanks | 00:47 |

| wgrant | Thanks. | 01:00 |
| cjwatson | no problem, not sure if the same needs to be done for pkgsel | 01:06 |
| cjwatson | I don't think I noticed it on an alternate install but I'll probably have to check again | 01:06 |
| * cjwatson falls over | 01:07 | |
| evand | heh | 01:08 |
| evand | oh wow, it's 1am | 01:08 |
| Samus_Aran | so I would like to know more about what the GUI installer is doing which takes such an exorbitant amount of time when custom-editing the partitions ? with several disks, it can take minutes of scanning | 02:19 |
| Samus_Aran | and why there is no option to do a straight partition editor like in other distros | 02:19 |
| Samus_Aran | once modifying any partition, it proceeds to do the lengthy scan again | 02:20 |
| Samus_Aran | and again after another change. it is mind-bogglingly slow and frustrating to install Ubuntu because of this, especially with 4+ disks | 02:20 |
| xivulon | evand, cjwatson there is a new version for patch #452348 | 10:46 |
| cjwatson | Samus_Aran: I'd like to optimise it, certainly; I know exactly what's happening and why, although a full explanation is a bit more than I want to go into on a Saturday morning, especially when you present it in such a confrontational way ;-) | 12:20 |
| cjwatson | Samus_Aran: in brief it's due to details of the way code is reused from the alternate/server installer; we most certainly do not want to have to maintain two partitioning programs, so I would far prefer to address this by optimisation rather than by rewriting, just haven't had the time yet | 12:21 |
| cjwatson | Samus_Aran: the answers you got on #ubuntu-devel (probing for other OSes, etc.) were not well-informed | 12:21 |
| Samus_Aran | cjwatson: so what would the summary be of what it's doing, if not probing for OSes ? | 12:23 |
| cjwatson | the way in which partman (d-i's partitioner) works is in some ways not a brilliant match for ubiquity. In order to reuse its behaviour, ubiquity needs to effectively drive partman back and forward under the covers in order to construct a useful graphical view | 12:24 |
| cjwatson | like I say, I already consider this an important bug that needs to be fixed | 12:24 |
| cjwatson | so you aren't going to make me consider it any more important by haranguing us ;-) | 12:25 |
| cjwatson | apologies for this "Moonraker12" character on #ubuntu-devel, no idea who he/she is but he/she was out of line | 12:25 |
| cjwatson | in fact, optimising the partitioner is already one of the things I've noted as a project I'd like to take on for the lucid cycle | 12:26 |
| Samus_Aran | what language is the partitioner programmed in ? | 12:27 |
| cjwatson | a mix of shell, C, and python | 12:27 |
| Samus_Aran | what's the majority share ? | 12:27 |
| cjwatson | I'm not sure of the answer, and I'm not sure that the answer would be helpful anyway :-) | 12:28 |
| cjwatson | there's C to interface to libparted; shell to do most of the business logic; and python to wire it up to ubiquity | 12:28 |
| cjwatson | any meaningful work on this will involve all three | 12:29 |
| Samus_Aran | well I am an expert at coding shell script, and can only read Python and C. if there is any optimisation to do in the shell script side of things, I could help out | 12:29 |
| cjwatson | I appreciate the offer, and you're welcome to look into this yourself if you wish, although there is a substantial learning curve | 12:29 |
| cjwatson | as I said, it is something I plan to tackle over the next cycle, assuming my manager thinks it's worth my time :) | 12:30 |
| cjwatson | you're incorrect that no caching happens, BTW, it's just not adequate caching ... | 12:30 |
| cjwatson | basically when ubiquity asks partman to perform an action, right now it doesn't always have a way to tell which partitions are going to be affected by that, and has to rescan rather too much as a result | 12:31 |
| cjwatson | I can think of some possible ways to remedy that | 12:32 |
| cjwatson | anyway, have to go out | 12:32 |

| arand_ | evand: may I bother you a bit? This is the update I want to test https://launchpad.net/ubuntu/+source/partman-basicmethods/43ubuntu1 unfortuantely I get stuck at the very beginning of your suggestion :( What is anna-install? from where should it be executed? (google ain't my friend). | 21:49 |
| cjwatson | arand_: I thought your problem was in the desktop installer, not in the text installer? | 23:09 |
| cjwatson | if so, anna-install is no help | 23:09 |
| cjwatson | arand_: if I'm right, open a terminal and run 'sudo apt-get update; sudo apt-get install ubiquity-frontend-gtk' (which will upgrade the installer) and then start the installer | 23:10 |
| cjwatson | arand_: oh, not until it gets processed through the queue though ... | 23:16 |

| cjwatson | arand_: (I think - that's untested) | 23:18 |
| evand | arand_: switch to a virtual terminal (ctrl-alt-f2) | 23:45 |
