| kens | Well, a desperate idiot Indian. mail to support, bug report and a posting on SO :-) | 07:55.06 |
| chrisl | Clearly so. If he posts an actual test file, I can try it on SPARC | 07:56.35 |
| kens | I thnk I pointed that out in the bug report | 07:56.51 |
| | It would be interesting to test on a Spar | 07:57.03 |
| | Grrr Sparc... | 07:57.09 |
| chrisl | You did, yes. SPARC is the only platform I have that enforces alignment, and the "bus error" rather suggests that might be the problem | 07:57.44 |
| kens | Yup, that's pretty much what I thought. On SO I told him he was going to have to do some debugging (it is a site for programmers after all :-) | 07:58.25 |
| chrisl | Even if his job description suggests developer, I'm sure he's not going to be up to that | 07:59.58 |
| kens | Nope :-) | 08:00.15 |
| sebras | kens: chrisl: doesn't a suitably configured ARM also enforce alignment? | 08:33.28 |
| | i.e. pi or something like it. | 08:33.42 |
| kens | sebras : possibly | 08:46.29 |
| | BUt to be honest, its not something I'm going to look into for a free user who hasn't done any work himself | 08:46.56 |
| | Oh, and so that a global logistics company can use GS for free..... | 08:47.16 |
| Robin_Watts | sebras: Some ARMs enforce alignment. Some ARMs just rotate the results. Some ARMs abort. | 08:55.55 |
| kens | \Well, my Pi has a ARMv7l, let me see... | 08:57.22 |
| | Apparently it raises an abort if the source/destination address is not word aligned | 08:57.58 |
| | Oh, though it also has a compatibility mode for non armv7 software | 08:58.45 |
| | The RISCOS page says that gcc 4.1.1 produces compatible code. | 08:59.33 |
| | Anyway, still not going to look at it. | 09:02.14 |
| chrisl | My RasPi didn't show a problem when I tried it for a similar issue before - I'd assumed it was a hardware/boot config option (like endianness) | 09:17.55 |
| kens | I'm seeing conflicting info on various pages | 09:18.13 |
| | So it may be configurable, I can't find a proper data sheet anywhere | 09:18.30 |
| Robin_Watts | kens: On some ARMs it is certainly software configurable. | 09:18.56 |
| chrisl | I didn't pursue it at the time, though, as I just had to find a power chord for my SPARC to work on the actual reported platform | 09:18.58 |
| Robin_Watts | suspects you mean a power cord. Though "chord" does conjure up a much better image :) | 09:19.39 |
| kens | Robin_Watts : some thngs ce3rtainly seem to be configurable on the v7 but I couldn't (quickly) find a dtaa sheet so I gave up | 09:19.57 |
| chrisl | Grr, just been talking guitars with someone else..... | 09:20.08 |
| kens | So hrisl is playing rock on his sparc ? | 09:20.11 |
| chrisl | TBH, it might be better as a musical instrument than as a computer these days! | 09:20.33 |
| kens | can understand the lack of a power chord on a Sparc these days | 09:20.49 |
| | Given that Chris can test alignment (fairly) easily, I gave up looking for more info on ARM alignment | 09:21.34 |
| Robin_Watts | kens: It's configuration typically done by the kernel.It's not something you can generally switch easily to do tests. So I agree that you shouldn't chase it. | 09:24.15 |
| kens | Yeah I was just reading the Linux how to on the subject | 09:24.31 |
| | It does look like Linux should throw an alignment error, whch is trapped in the kernel and I *think* should give a seg fault. | 09:25.02 |
| | Sorry ARM should throw an alignement error..... | 09:25.15 |
| | There's infor on finding out how its set up, but hey, getting bored now | 09:25.50 |
| chrisl | You can set it to seg fault, too. | 09:26.01 |
| | But also if only enforces alignment to word boundaries, that's not the same as SPARC - I can't remember what IA64 does.... | 09:27.03 |
| kens | Beats me, I'd have to go look that up too | 09:27.20 |
| | TBH its up to the person askign to reproduce it on a more mainstream device, or debug it himself. | 09:28.01 |
| | He obviously must have *built* it himself..... | 09:28.12 |
| chrisl | I also don't want to waste any more time on (probably) a freeloader | 09:28.26 |
| kens | Oh I'm sure they are a freeloader. I bet they want their reports (invoices etc) in PDF format, and tehy currently come out in PCL, so they want to use GS to do the work. | 09:29.05 |
| tor8 | Robin_Watts: Thanks, and yes, I think we'll need someone to build and upload the iOS version. | 09:36.09 |
| | sebras: font size can be changed with a command line argument | 09:36.28 |
| | sebras: I need to add @page at-rule parsing and handling for customizable margins, then we can add user stylesheets | 09:37.02 |
| sebras | tor8: ah, I didn't notice that. | 12:03.09 |
| dyfrgi | x86-64 enforces alignment for some instructions. There are non-enforcing instructions for the same thing, but the alignment-enforcing ones are used by gcc sometimes. | 12:55.37 |
| kens | I'm not sure NOrbert is listening to me..... | 13:29.41 |
| henrys | kens: yeah that the one where the raster op device is loaded in the image code and pdfwrite never sees it. | 14:26.53 |
| | s/that/that's | 14:27.15 |
| kens | henrys, I guessed it was a ROP | 14:29.36 |
| henrys | kens: oh lord hin-tak is on it. | 14:29.53 |
| kens | O.O :-( | 14:30.02 |
| | Well he's more or less saying pretty much what I already did. Its not part of the graphics model, in the general case we can't handle it in PDF, so an image is all we can do. | 14:31.10 |
| | I don't think the bug he's referring to is relevant either, since the output is to pdfwrite. | 14:32.18 |
| henrys | kens: yes he's just bringing up stuff stuck in his craw | 14:34.00 |
| kens | Not helpful...... | 14:34.23 |
| chrisl | If we make a bug private, can the original reporter still see/post on it? | 14:35.25 |
| kens | I don't know what (if anything) you thnk we should do about this Henry ? It may be that ths particular ROP cna be transformed into something acceptable to PDF< but we know that in general ROPs can't. | 14:35.45 |
| henrys | kens: I'm going to close it. | 14:36.18 |
| kens | Fine by me :-) | 14:36.26 |
| rayjj | darn, yet another 'membership disabled' message from gs-devel (and with the same confirmation string). looking at my trash, the first time this message was sent was on Apr 23rd, and I probably missed it. | 14:41.15 |
| chrisl | rayjj: if you want to try shouting at GMail, then have it - we rather figured they'd just ignore us..... | 14:42.20 |
| henrys | kens yeah you analyzed this same issue 3 years ago: http://bugs.ghostscript.com/show_bug.cgi?id=692853 comment #3 . Don't you remeber ;-) | 14:43.24 |
| kens | I have the same kind of early Alzheimer's as Robin....... | 14:43.47 |
| | Chris on the other hand seems to have the proverbial elephant's memory | 14:44.04 |
| chrisl | For some things..... | 14:44.20 |
| Robin_Watts | kens: I have what? | 14:44.39 |
| kens | Eh what ? | 14:44.47 |
| henrys | how are ya'll doin' with the new gov't? | 14:45.15 |
| kens | Its less amusing than it could have been :-) | 14:45.30 |
| Robin_Watts | henrys: It's like the old government, but with the stabilisers taken off. | 14:46.12 |
| henrys | I just read the conservatives did a bit better | 14:46.44 |
| chrisl | I can't say I'm surprised by the LibDems' results.... | 14:46.47 |
| Robin_Watts | In 18 months we'll have an in/out referendum for europe. | 14:47.00 |
| | I suspect at that point, Scotland will want to stay in, and the rest of the uk will want out. | 14:47.23 |
| henrys | you guys should be a separate continent | 14:47.31 |
| Robin_Watts | and that'll set us up for another independence question. | 14:47.41 |
| | henrys: We've had continents before, but you and India wanted out :) | 14:48.23 |
| henrys | you can barely hold on to scotland now... | 14:48.53 |
| kens | I think Millipede's comments about the SNP probably didn't help Labour | 14:51.30 |
| Robin_Watts | s/'s comments about the SNP// | 14:51.48 |
| kens | Well that too, but I meant in Scotland | 14:52.06 |
| | TYring to threaten people, and coming over all strong man when Sturgeon was being reasonable doens't really play well | 14:52.32 |
| Robin_Watts | I think the SNP massively helped the conservatives :) | 14:52.34 |
| kens | Yeah, Cameron must be delighted | 14:52.47 |
| Robin_Watts | "On friday, I'll be sitting across a table from Ed Milliband discussing how to kick the Tories out". | 14:53.02 |
| kens | The referendum was a bit of a gamble, but its paid off for him big time | 14:53.07 |
| Robin_Watts | That played really well in england. | 14:53.31 |
| kens | No doubt | 14:53.38 |
| | Same as the '10% holding to ransom' played well in Scotland | 14:53.52 |
| Robin_Watts | Gotta reboot. Windows is evidently a labour supporter and sulking... | 14:54.18 |
| | .quit Pop! | 14:54.22 |
| chrisl | And yet again, our gs-regression mails are being filtered as spam - HOW MANY TIMES GMAIL, HOW MANY TIMES? :-( | 14:56.54 |
| kens | Yeah, mine too, but only some of them...... | 14:57.06 |
| | And you have to individually forward them too (or if you can mass forward I can't figure out how) | 14:57.34 |
| chrisl | I just copy them | 14:58.05 |
| kens | CC ? How does htat help ? | 14:58.28 |
| chrisl | No, I copy them out the spam folder, into my regression folder | 14:58.45 |
| kens | Ah but I want them sent to another account | 14:58.54 |
| | Mail whch doesn't get spam filtereed is auto-forwarded to another account (because I cna't do password authenticaton on commercial GMail). But if it goes into spam, I have to mark it as not spam and forward it manually | 14:59.43 |
| Robin_Watts | chrisl: I suspect bug 695913 should be thee, not me. | 16:15.33 |
| | I can try to verify it if you want. | 16:15.48 |
| chrisl | Okay, I'll take it | 16:16.48 |
| henrys | huh the internal font name encoded in the font for the urw wingdings we got recently is URW Dingbats. I wonder if that is intentional to avoid trademark issues or a mistake. It is confusing since Dingbats is a different font. | 16:32.25 |
| | my turn for forgetfulness, I already knew that. | 16:41.58 |
| | marcosw: for the logs I've sent off the ghostpdl support issue to scott and miles so they can try and get a support contract. | 16:57.30 |
| Robin_Watts | I see the problem with the bicubic scaling. | 18:33.09 |
| | bicubic scaling is suitable for *upscaling* only. | 18:33.20 |
| | For downscaling it just doesn't work. It's actually worse than linear. | 18:33.56 |
