Robin_Watts mvrhel: If you use Chrome, then look for 'google input/output' in the chrome webstore.00:00.08 
mvrhel dinner time. bbiaw00:02.19 
henrys Robin_Watts:still working on the fill code - uncovered a few gl/2 bugs in the process. HP's path code is insane.00:04.10 
Robin_Watts henrys: What phone do you have?00:06.23 
henrys iphone00:06.52 
Robin_Watts Can you tether to that?00:07.17 
henrys no I haven't broken it or ordered tethering.00:07.41 
  sabrina just told me we wouldn't have internet at a couple of places. You have internet in bhutan and I can't have it in the UK?00:08.30 
Robin_Watts henrys: I can loan you my cell phone overnight while you're at the horse and groom. That can be a wifi hotspot (assuming the cellphone can get service).00:09.11 
henrys it really isn't a big deal I can last a few days without the internet, hell I might do something useful without it.00:10.39 
  your up late!00:10.59 
Robin_Watts henrys: I keep trying to tell myself that too, but the shakes set in after about 12 hours of no IP packets.00:12.34 
  Yeah, just off to bed...00:12.44 
henrys good night I'm heading out to dinner.00:13.16 
debjan1 Hello. I cloned MuPDF git on Ubuntu 11.04. By default it builds fine, but I was asked to make shared library, and I tried by adding "-fPIC" in CFLAGS variable in Makerules file. However I get same result as w/o "-fPIC" so I guess it's not so trivial. Can someone suggest how it could be possible?03:28.11 
ccotton_ Thanks Robin_Watts for the info04:54.51 
kens What a wonderful comment :07:43.21 
  * Write the Cos objects for resources local to a content stream. Formerly,07:43.22 
  * this procedure also freed such objects, but this doesn't work, because07:43.22 
  * resources of one type might refer to resources of another type.07:43.22 
  So instead of fixing the problem, we just decided to stop freeing memory....07:43.41 
vtorri it reminds me some weird commit in openjpeg07:52.57 
  they use winsock 207:53.10 
  but including winsock2.h breaks compilation07:53.34 
  they found that including winsock.h does not break compilation07:53.53 
  so they included it instead of winsock2.h...07:54.07 
kens :-)07:54.12 
  In my case it leads to pdfwrite leaking hundreds of memory allocations....07:54.31 
vtorri i told them it was very wrong07:54.34 
  hiding bugs...07:54.44 
  hehe07:54.46 
  of course :)07:54.51 
kens Yes, hiding bugs is bad.07:54.53 
  Its taken me a week to figure this one out07:55.19 
vtorri valgrind couldn't help ?07:55.37 
  btw, i left the openjpeg project because of that07:55.50 
kens Afraid not.07:55.50 
  Its a double free in our own memory allocator. It only shows up if the first free sets a particular part of the freed structure memory to 0.07:56.20 
vtorri i can't work with devs that can't understand that hiding bugs like that is very bad07:56.28 
  ha07:56.35 
  ok07:56.37 
kens I could only reproduce the problem at alll on a 64-bit Linux with a specific configuration.07:57.04 
  Even then, in our 5,000+ tests it only shows up in about 15 cases07:57.29 
  50,00007:57.35 
  But there it shows up as a seg fault07:57.52 
  Debugging using ddd over ssh is not my idea of a fun time ;-)07:58.32 
vtorri :)07:59.46 
kens btw chrisl, that comment explains the 'half cocked' apporach to memory management in pdfwrite. At some point the memory was properly tracked and freed, then someone (I can take a guess at who) found that problem, and removed half the code that frees memory, leaving the remainder in place....08:03.07 
naveen_ Hi Robin, I tried to encrypt a file and decrypt the same file with the functions in muPDF...but the decrypted file is not same as the original file...Any ideas?08:04.55 
kens naveen_ : Not the same in what way ?08:05.17 
naveen_ decrypted file is corrupted and I'm not able to open in adobe reader..08:05.48 
kens Ah, well not what I was thinking of then.08:06.01 
  What kind of encryption are you using ?08:06.16 
  BTW naveen_ Robin_Watts probably won't be here for another hour to an hour and a half08:06.56 
naveen_ ohh..can you help me on this?08:07.28 
kens Not a lot, I'm not really a MuPDF developer, I work on Ghostscript08:07.44 
naveen_ ok thanks...I'll contact Robin when he is in..08:07.59 
kens NP, as long as you know you'll need to wait a bit :-) I'm sure he will read the irc log08:08.38 
vtorri kens: btw, one question about gs08:13.25 
kens yes ?08:13.32 
  Don't guarantee I can answer though08:13.40 
vtorri for our rendering library, i use libspectre08:13.43 
  which is a wrappper above libgs08:13.57 
kens Yep08:14.01 
vtorri i would like to remove that layer08:14.15 
kens OK08:14.26 
vtorri would it be difficult to just use libgs for a rendering ?08:14.33 
kens vtorri I don't see why it would be difficult08:14.43 
vtorri i didn't look at libspectre code08:14.49 
  (yet)08:14.55 
  so08:14.57 
  is there some simple examples somewhere ?08:15.08 
kens Well you can get GS to return you a buffer with a bitmap in it, which should be enough I woudl think08:15.11 
  The WIndows display device does that.08:15.21 
  'simple' and Ghostscript shoul d never appear in the same sentence....08:15.36 
vtorri hehe08:15.56 
  i think that i already did something similar with dvilib08:16.16 
  (similar than libspectre)08:16.28 
kens The simplest solution is probably to look at a few of the existing devices. But if it was me, I think I woudl start with teh display device on the relevant OS08:16.35 
  Linux ?08:16.48 
vtorri all08:16.53 
  unix + windows08:16.56 
kens Umm, I'm not so familiar with teh Linux display device(s)08:17.15 
vtorri more precisely : linux, bsd, mac, solaris and windows08:17.15 
kens I guess all you really want is a memory full of image smaples ?08:17.30 
vtorri yes08:17.37 
  i want the (a)rgb data of page N08:17.50 
kens alpha is a problem08:17.58 
  I don't know much about that08:18.12 
  chrisl you know anything about this topic ?08:18.49 
  I guess the PNG device might be a decent start08:19.28 
vtorri http://cgit.freedesktop.org/libspectre/tree/libspectre/spectre-device.c#n21408:20.12 
  it seems that they use the 'display' device08:20.23 
kens Yes, which is what I was suggesting too :-)08:20.31 
  Because it returns a bunch of samples in memory08:20.53 
  That should be easy for you to code I woudl think08:21.14 
vtorri yes08:21.22 
chrisl Sorry, I'm dealing with the guys fitting a new back door just now.......08:21.28 
vtorri that libspectre layer is, imho, useless08:21.31 
kens Well, some people seem to find it helpful, I've never looked at it myself08:21.49 
vtorri dev is halted since 201008:22.04 
kens Oh, that's not so good.08:22.14 
chrisl FWIW, if all you're after is a big ole' raster, then the display device is where I would go. The only thing is, I'm not sure it supports banding.08:22.52 
kens That code looks like it was cobbled up from our Windows code08:22.57 
vtorri and is there some multithreading stuff in libgs ? :)08:23.34 
kens chrisl if the libspectre code is good enough for vtorri now, and it uses the display device, then its probably fine.08:23.47 
  vtorri, only for rendering from display list08:23.54 
  interpretation is a mostly single threaded operation really08:24.11 
vtorri ok08:24.16 
  thank you08:24.49 
kens NP08:24.55 
vtorri not really related, but is there some DVI library except DVIlib ?08:25.32 
chrisl kens: yes, I just figured it might be worth mentioning, just in case.08:25.49 
kens I have no iodea, sorry08:25.52 
vtorri ok08:25.54 
chrisl I doubt there is a widely used/available well supported DVI implementation other than dvilib, due the patent problems with the format.08:26.38 
vtorri really ?08:26.54 
  there are still patents ?08:27.01 
  i thought the format was quite old08:27.11 
chrisl The are still unexpired patents relating to it, I believe08:27.50 
  It is old and basically dead - it's hard to get an "open format" accepted when it involves patents that are being enforced08:28.48 
vtorri ok08:29.00 
  it's not dead for me, as i use LaTeX in my work08:29.22 
  (and not pdflatex)08:29.32 
chrisl Can't latex output straight to PS these days?08:30.29 
vtorri don't know08:31.24 
  i compile with emacs (+auctex)08:31.38 
  i didn't look at all the compile options08:31.49 
Robin_Watts naveen_: Morning09:28.52 
  I have no immediate ideas about the encryption stuff beyond what I said yesterday.09:29.33 
  Have you verified that both java and C versions of the code are giving the same keys ?09:29.56 
naveen_ Hey Robin..are you in?09:30.38 
  Morning ..09:30.52 
Robin_Watts I am.09:30.53 
naveen_ I have verified both java and c versions....key is same09:31.20 
  I tried to encrypt the file with "aes_crypt_cbc" and decrypt the same file with "aes_crypt_cbc"09:32.18 
  but the decrypted file was not same as original file09:32.43 
  Any idea why this is happening?09:33.45 
Robin_Watts None at all.09:34.26 
naveen_ ideally decrypted file should be same as original file..fight?09:34.47 
  right*09:34.55 
Robin_Watts Are you saying you're using the C code to encrypt the file,then using the C code to decrypt it again?09:35.14 
naveen_ yes..09:35.21 
Robin_Watts I'm not sure we ever use the C code to encrypt.09:35.29 
naveen_ hmm...do you think there is something related to signed/unsigned cnars ?09:36.35 
Robin_Watts I don't see why.09:36.44 
  Certainly encryption -> decryption *should* give the same file - that's kind of the whole point.09:37.16 
  but being encyption it's very sensitive to correctness - the smallest detail wrong will give completely different results.09:37.53 
  It's hard for me to debug blind...09:38.09 
naveen_ Can you just try encrypting & decrypting some file using my code?09:38.38 
Robin_Watts naveen_: Sure. If you can share your code with me, I can try it out.09:38.58 
naveen_ http://pastebin.com/N0mJdyJk09:40.17 
  just add some logic to populate m_key 09:40.41 
Robin_Watts ok. It's going to be an hour or 2 before I get to this, I fear, sorry.09:42.23 
naveen_ ok...NP09:42.47 
Robin_Watts naveen_: Just looking at the code now.10:44.41 
  When you 'encode' you presumably call aes_setkey_enc and use AES_ENCRYPT, right?10:45.41 
naveen_ right10:51.10 
  ohh sorry I was using "aes_setkey_dec" even for encryption10:51.54 
Robin_Watts That may explain it10:54.12 
  OK. My test works.10:56.35 
  http://ghostscript.com/~robin/test.c10:57.04 
naveen_ yup it works..10:59.03 
Robin_Watts fab.10:59.08 
naveen_ I need to figure out why my file is not getting decrypted properly... :(10:59.25 
Robin_Watts naveen_: Did you say before that there were 512 header bytes before the first block ?10:59.50 
naveen_ yaa..I'm removed it actually11:00.15 
Robin_Watts ok, so it's not that...11:00.24 
  Presumably somewhere in those 512 bytes the real size of the file is encoded?11:00.45 
naveen_ yaa..its not that...11:00.50 
Robin_Watts You're running under cygwin, right?11:01.10 
naveen_ yes11:01.14 
Robin_Watts ok, so no windows crlf rubbish.11:01.27 
naveen_ md5 digest is signed in java where as it is unsigned in C..do you think that will make a difference?11:16.01 
Robin_Watts No.11:16.58 
  naveen_: If you give me a file, and the key for that file, I can then encode/decode that file, and we can check it compared to the java version.11:39.11 
  That way you'll be giving me a single key, not the key generation mechanism itself, so you won't be sharing anything important.11:39.35 
  Does that sound acceptable ?11:39.39 
naveen_ Robin..I got this to work...like you said I was writing some extra bytes....11:50.37 
Robin_Watts oh, fab.11:50.53 
naveen_ So now I see read_file function...Can you explain how should I pass the data to it..11:51.51 
Robin_Watts Well, you're presumably implementing a new read_file, function, read_encrypted_file or something, right?11:53.17 
naveen_ right ..11:53.31 
  how much data will it expect each time ?11:54.18 
Robin_Watts No, you've got this wrong.11:54.35 
  Juet let me pull up the code.11:54.51 
  read_file will be called with a buffer, and a length.11:55.33 
  It's your job to read the next len bytes from the file and put that into the buffer.11:55.58 
  If you read less than n bytes (because you hit the end of the file) then you should return the number of bytes you do read.11:56.29 
  The important thing to realise is that you aren't just walking through the file "in order" - seek_file may be called to change the position within the file, and the next read_file should then read from that position.11:58.01 
  So, on a given read, a naive implementation would grab the appropriate 64K from the file, decrypt it, and copy out the required bytes.12:00.04 
naveen_ hmm...as my file will be encrypted.. do i need to get the file pointers current position...based on the postion get the block and decrypt the data and send it in buffer...is that right?12:00.07 
Robin_Watts You have to be careful to allow for the idea that a fetch might straddle 2 blocks.12:00.48 
  (or more, potentially)12:00.56 
naveen_ but I'll be able to get the file pointer position..right?12:01.22 
Robin_Watts You can put anything into stm->state that you want.12:01.45 
  I suspect you'll want that to be a structure that contains things such as:12:02.13 
naveen_ but how would I know from which position of the file to read from..12:02.19 
Robin_Watts 1) The position that was last seeked to.12:02.23 
  (or rather the 'file position in the decrypted file')12:02.42 
  2) some buffers to use.12:02.51 
miha hmmm trying mupdf on android... got libmupdf cannot parse token in array for some pdf (might be incomplete, but still it shouldnt just hang?!)12:03.00 
Robin_Watts 3) the decryption key12:03.01 
sebras miha: do you have that file available?12:03.45 
Robin_Watts naveen_: Given that you'll be reading data from the *real* file in 64K chunks, the *real* fileposition will be different from the fileposition as far as mupdf is concerned. Does that make sense ?12:03.51 
  miha: We'll look into it, but as sebras says, we'll need a file.12:04.17 
miha sebras: will see, might be i tried to open before download finished.. but still some dialog would be nice instead of just hanging infinetly12:04.39 
Robin_Watts miha: Does the same file cause hangs on windows?12:04.49 
naveen_ hmm...so I don't need to bother about fz_stream...I need to maintain my own fileHandler here...is that right?12:05.12 
Robin_Watts miha: The android app can't even try to open a file before the download finishes, AIUI.12:05.17 
  naveen_: fz_stream is the abstract interface that mupdf calls to read data.12:05.43 
  You need to provide an fz_stream otherwise mupdf won't be able to work on your data.12:06.03 
  But we have lots of different fz_stream implementations; one works from memory, one works from a file etc.12:06.28 
  All you are doing is copying the fz_stream file based implementation and modifying it so that it will work from an encrypted file.12:06.59 
  On the outside it will look like a normal fz_stream. but on the inside it will work differently.12:07.21 
sebras miha: we'd be grateful if you could attach the file over at bugs.ghostscript.com and we'll take a look at it. I'm a bit surprised that mupdf hangs completely though.12:07.24 
Robin_Watts Do you see what I am trying to say ?12:07.28 
naveen_ yes..I get that Robin...Will work on that and will update you on the progress..12:08.05 
Robin_Watts naveen_: Cool. Let me know how you get on, and if I can help.12:08.22 
naveen_ sure..Thanks...12:08.35 
Robin_Watts naveen_: It's worth saying that mupdf seeks around a LOT while reading from the file.12:08.40 
  We may only read a few bytes at a time before seeking off somewhere else to read from there.12:09.00 
  so it's probably worth making sure that the code copes efficiently with seeking.12:09.21 
naveen_ ok..I'll try to do it efficiently...12:09.55 
Robin_Watts (i.e. maybe only decrypt part of the 64K at a time? At least make sure that if we seek within the 64K block we don't refetch/redecode it.)12:09.58 
  miha: If you can open a bug and attach a file, then I'll look into it after lunch.12:11.03 
naveen_ ok..got that..12:11.20 
miha Robin_Watts: i still think i open it too soon :)12:34.48 
sebras miha: ok, if you can not reproduce it then that's good. maybe we should take a look at the parsing code anyway to make sure that there are not infinte loops lurking there still...12:43.51 
miha sebras: either it cant parse or it cant lock file. in both cases it should display dialog12:46.47 
  it doesnt always crash, sometimes it just shows waiting :)12:47.16 
  now i make sure it's .pdf.tmp while downloading so i dont open too son :$12:48.07 
  otherwise it's pretty awesome :)12:48.38 
  good work12:48.42 
  sebras: if you want to reproduce, just truncate .pdf .. it happens often enough :)12:52.23 
Robin_Watts I suspect it's probably the repair code hunting for a trailer.12:56.17 
  i.e. it's not hung, it's just taking a long time. Or something like that.12:56.29 
sebras Robin_Watts: maybe we should have the progress-argument indicate how far in the file it has searched?12:59.47 
  Robin_Watts: maybe we already do. I haven't checked.13:00.15 
Robin_Watts sebras: Urm... searching is based on the text extraction device.13:00.20 
  We feed the text extraction device from the list device.13:00.27 
  The list device is the thing that updates the cookie.13:00.47 
  Oh, we might be feeding it direct from the interpreter. Let me see if that does the cookie.13:01.06 
sebras I think we do.13:01.16 
  and if so we may be able to have the repair code do something similar.13:01.38 
Robin_Watts I'd like to reproduce the problem before hunting for solutions...13:03.01 
sebras Robin_Watts: naturally.13:03.12 
  I'm surprised that he mentions crashes.13:03.33 
  doesn't the android-app print something nicely upon exceptions?13:04.04 
Robin_Watts pass.13:05.02 
kens often people think crash = error message13:08.03 
Robin_Watts I don't think the android app does anything nice when it crashes - I think it just exits. paulgardiner ?13:09.47 
  (of course, it never crashes, so... :) )13:09.58 
sebras Robin_Watts: I was thinking about calls to fz_throw.13:10.27 
Robin_Watts If we fz_throw without an fz_try in place, then it just prints to stdout and exits, I belive.13:11.01 
  believe.13:11.07 
sebras Robin_Watts: right. maybe that should be printed to a dialog as in the windows app. I think stdout is only sent to logcat or so.13:14.11 
Robin_Watts It does only go to logcat.13:14.30 
  and I'd rather we just made it so that it could never happen.13:14.45 
  (fz_throws always being within an fz_catch should be something we can guarantee)13:15.09 
sebras fz_document functions seem like a good candidate. I'm not sure if tor8 has any opinion on it though.13:16.38 
Robin_Watts The fz_document functions are defined as throwing exceptions I think (I'd need to check with the bloke that wrote the docs :) )13:17.15 
sebras Robin_Watts: he might know, yes. ;) but the interface may be up for change.13:21.43 
Robin_Watts Well, I'm damned if I understand bug 692847. OR specifically zenikos fix.13:24.47 
sebras Robin_Watts: ok, so there are patterns with huge tiling bounding boxes (larger than the desitination areas), so instead of drawing and then scaling down he draws the pattern without tiling at all...?13:30.33 
  Robin_Watts: I might be able to see how that could be faster, but I'm not sure if the drawn region would be correct. in fact I would easily be convinced that it would not be.13:31.21 
Robin_Watts Surely the right thing to do then is to reduce the tiling bounding box to match the destination area?13:32.03 
sebras Robin_Watts: that seems like the best solution to me. unless there is some fiddling with subpixelcoordinates at the borders or so.13:33.27 
  Robin_Watts: I can see why he chose 50 though.13:36.28 
  Robin_Watts: (5000x5000) / (500x500) = 100, which means the pattern is drawn scaled down 100 times.13:37.53 
tor8 sebras, Robin_Watts: display list execution also updates a cookie14:03.37 
Robin_Watts tor8: yeah.14:03.47 
tor8 Robin_Watts: I think we can get around the case where the tile bbox is much bigger than the drawn content (that's what I read is happening here) in a more roundabout way using the bbox device to pre-compute the real bounds14:04.31 
Robin_Watts tor8: I have a fix for this particular file that's much simpler14:55.47 
  In fz_draw_begin_tile, if the calculated view bbox (i.e. pat->bbox * ctm) entirely encloses the region we are writing to, then just chop it down to that size.14:58.35 
  The thing is, that case is a sub case of "is only 1 tile required to cover the output", so I think the above test must be wrong somehow.15:00.04 
  s/above test/test in the function above/15:00.32 
  paulgardiner: Your forms report sounds great -real progress!15:04.52 
  I reckon we should make a forms branch, and publish that to casper. We can periodically pull master into it to keep it up to date.15:05.42 
  marcosw: I updated pngs2html to pull stuff into the webpage.15:07.29 
marcosw it now looks at the .out files?15:08.03 
Robin_Watts It does.15:08.07 
  Also, a pet peeve of mine; if you update my perl (which I accept is required at times) please can you keep the indentation correct?15:08.52 
  You added an if (blah) { .... } around a block to work around an error case, but didn't indent the block inside.15:09.32 
  I understand the reasoning (not wanting to cause lots of diffs), but I'd rather take the diffs than have me get all confused by not following my code afterwards :)15:10.34 
  (I'm sure I do things that you find similarly annoying when I edit the cluster code, and I apologise for them - if you tell me what, I'll try and avoid them in future).15:16.18 
ray_laptop diff -w ignores whitespace 15:26.56 
  in vimdiff use :set diffopt=iwhite15:29.12 
Robin_Watts ray_laptop: Yes. I'd rather have to use -w than get spend time wondering why my file no longer works because I've inadvertantly deleted a } that didn't have the associated whitespace before it.15:29.29 
  s/get/15:29.35 
  marcosw has a style of adding new if (...) { ... } stuff to perl files without indenting the contents. (The cluster code has many such cases in). His brain is clearly able to cope with it. Mine is not that flexible. :)15:31.06 
marcosw Robin_Watts: this is why I don't like python :-)15:31.35 
  when it becomes too bad I run ~cluster/bin/mytidy, which cleans up the indenting.15:32.30 
Robin_Watts Can we put that on a cron job? :)15:32.41 
marcosw ^~cluster^~regression15:32.42 
  causes lot of whitespace differences, so makes git blame less useful, otoh, since the clutter code changes are all committed by user regression blame isn't very useful15:33.41 
  I'll go ahead and run tidy on the cluster code now (after checking the current code into git).15:34.06 
Robin_Watts marcosw: My ailing brain thanks you :)15:34.24 
ray_laptop Robin_Watts: on another topic -- when I do a command line "git commit -a" it pops up a 'vim' edit window, which is what I want, but the syntax highlighting is really funky -- it wants to put my message in yellow on a white background.15:34.40 
  Robin_Watts: is there a way to for :set syntax=off for the git message edit session ?15:35.15 
Robin_Watts feels like this is like complaining that you might get splinters from the guillotine, but...15:36.10 
  ray_laptop: Is the syntax editing any different than you'd get by invoking vim manually ?15:36.53 
  Presumably there must be a .vimrc or something?15:38.20 
ray_laptop hmm... nope. I tried "vim ../.git/COMMIT_EDITMSG" and it looks the same. But with 'givm' it looks OK. So maybe it is using a different vimrc15:38.33 
kens Well, let's see how long this lasts ;-)15:38.51 
ray_laptop kens: how long what lasts ?15:39.11 
Robin_Watts ray_laptop: So vim ../.git/COMMIT_EDITMSG has the horrible coloring?15:39.18 
kens My internet connection....15:39.20 
  chrisl from teh status page :15:40.21 
  "At approximately 4.00pm BT Wholesale suffered an unexpected network outage that disconnected a significant number of our broadband customers."15:40.21 
Robin_Watts and what's givm?15:40.27 
ray_laptop Robin_Watts: yep. Is there a way to tell git to use gvim instead of vim (as was the case with SVN_EDITOR= and svn) ?15:40.53 
Robin_Watts EDITOR?15:41.06 
  I have: export EDITOR=emacs in my .bashrc15:41.37 
ray_laptop Robin_Watts: gvim is a windows port of vim -- runs in a separate process, supports cut and paste to the clipboard, that sort of stuiff15:41.44 
Robin_Watts Ah.15:41.49 
  Well export EDITOR=gvim15:42.00 
ray_laptop Robin_Watts: thanks. That works !! :-)15:42.25 
chrisl kens: well, at least you know what happened......15:42.27 
Robin_Watts ray_laptop: Fab.15:42.34 
henrys in ~/git/.gitconfig I have [core] editor = /Applications/Emacs.app/Contents/MacOS/Emacs15:42.35 
  15:42.35 
  sorry ~/.gitconfig15:43.07 
Robin_Watts export EDITOR=emacs works on macos too.15:43.09 
ray_laptop henrys: thanks. I'll try that, but in case there are other msys apps that use EDITOR, I generally want gvim anyway15:43.46 
Robin_Watts The unix (and hence msys) convention is to use EDITOR (or VISUAL if that's set)15:44.21 
  So for belt and braces, set both.15:44.32 
marcosw Robin_Watts: perltidy.pl found errors in bmps2html.pl:15:45.44 
  Scalar found where operator expected at bmps2html.pl line 87, near "$javascript"15:45.51 
  (Missing semicolon on previous line?)15:45.51

  (Missing semicolon on previous line?)15:45.53 
  syntax error at bmps2html.pl line 87, near "$javascript "15:45.53 
Robin_Watts Fixed. THanks.15:46.36 
marcosw perltidy run and the results committed and pushed15:49.33 
henrys As a linux user I've always used EDITOR, I tripped over something on macos and I can't remember what it was - anyway, right EDITOR is best.15:50.09 
Robin_Watts henrys: I've ordered a USB 3G mobile broadband dongle thing, so you can borrow that while you're in the country.15:51.51 
  So as long as you're not so far out in the sticks that you have no mobile coverage you should be OK.15:52.15 
henrys well now I've found out we are going to have wifi at the pub/inn - I'll just be dark on the sheep farm - probably best ;-)15:53.07 
marcosw anyone have any idea what might have changed on casper? I'm getting a new warning from bugs.ghostscript.com: The local XML file '/var/www/bugs.ghostscript.com/data/bugzilla-update.xml' cannot be created. (you may not see this message, it's generated by the code that checks if there is an updated bugzilla available, which only occurs if you are logged in and listed as a bugzilla admin)15:53.41 
henrys Robin_Watts:so you use that a lot?15:54.21 
  a cellular network for internet that is?15:54.46 
Robin_Watts I don't as a rule. I have done in the past when my broadband has died.15:55.08 
  And when I'm at heathrow, my cellphone will do the "be a wifi hotspot" thing.15:55.26 
chrisl marcosw: I installed a couple of applications a couple of days ago, but that wouldn't have caused that problem....15:56.06 
Robin_Watts My next door neighbour used a 3G dongle for ages before getting broadband put in.15:56.09 
henrys oh you're like a homeless person in the united states.15:56.13 
Robin_Watts will code for food ?15:57.25 
henrys well I guess if you have unlimited data it's okay but kind of pokey no?15:57.30 
Robin_Watts I have unlimited data on my monthly plan (limited to 500Meg or something on the dongle, before it throttles)15:58.32 
  no, mobile broadband speeds here are quite decent, I think.15:58.57 
marcosw henrys: I tether my iPhone 4s to my laptop occasionally and it's faster than you'd expect. The biggest problem is that it only supports http (and https), so no ssh or irc (I use a web to irc gateway, so it's only ssh that I can't use).15:59.39 
Robin_Watts Well, 2Mbps or so seems typical, which is about average for ADSL in the sticks (though I get 8 now. Weee!)15:59.54 
henrys wow that is faster than I thought.16:00.47 
Robin_Watts marcosw: It's possible that since you updated casper to the new ubuntu, web stuff has run with less permissions.16:02.53 
marcosw Robin_Watts: I think I would have noticed this warning before now. 16:03.10 
Robin_Watts I think there was a problem with the delta stuff to do with that. (Though it was masked by larger problems for a while)16:03.20 
Robin_Watts points excitedly at the lovely empty mupdf deltas :)16:04.00 
marcosw I checked the casper backups and bugzilla wrote to this directory on the 17th. So something changed in the last two days.16:04.00 
  Does anyone object if I reboot casper? mvrhel just started a clusterpush, but I'll restart that after it's back up.16:04.46 
kens marcosw I put a copy of ghostpdl in my directory, don't see how that could have affected it16:04.58 
marcosw I don't think it's anyone did, I think bugzilla has become confused. This happened before, though the symptoms weren't the same.16:05.42 
henrys You bastards!16:09.42 
  south park humor ...16:10.22 
marcosw you guys suck, I'm going home!16:10.25 
  unfortunately bugzilla still display the warning!?16:11.03 
kens permissions problem ?16:11.22 
  Time to be off. On the plus side, my fix for patterns in pdfwrite is OK, so I've committed it to my branch.16:12.39 
  Goodnight all16:12.44 
henrys alexcher:yikes 2 week customer bug without a comment ... 69296916:32.48 
alexcher henrys: The file has one incorrect object. We try to rebuild xref but cannot do this for PDF 1.5. 16:44.28 
  henrys: The file runs to completion if we drop xref verification.16:45.05 
  henrys: I plan to do it for the files with object streams.16:45.39 
mvrhel marcosw: I am getting close to having this sep planar stuff done. some of the diffs I have in bmpcmp are actually progression16:45.47 
  s16:45.49 
henrys but we agree a customer bug shouldn't sit for 2 weeks with nothing - marcos reports the numbers back to the customer they check it and see absolutely nothing, it's not ver good, right?16:46.17 
marcosw mvrhel: great, I'm not going to tell Gemma, no point getting her hopes up.16:46.28 
mvrhel right16:46.37 
marcosw henrys: that is what the bug aging report is supposed to be used for, it lists the number of days since the bug owner last commented on the bug.16:47.03 
ray_laptop alexcher: we should be able to rebuild the xref if we decompress the object stream, right ?16:47.54 
henrys marcosw:yes and I missed it.16:48.01 
alexcher ray_laptop: yes, we should but this is not yet implemented.16:48.46 
ray_laptop mvrhel: I'm really looking forward to seeing what the performance difference (hopefully improvement) will be.16:49.14 
Robin_Watts mvrhel: The information from the bmpcmp email should now be in the bmpcmp webpages too - please let me know if you see anything odd with it.16:49.42 
ray_laptop I should run some files now as baselines, so I can compare them after your commit16:49.49 
mvrhel ray_laptop: with transparency present we should see some improvement. I have not done any timings yet16:49.51 
henrys alexcher:please add analysis to customer bugs promptly (days), I understand if it takes a while to fix but most problems can be analyzed quickly.16:50.33 
alexcher henrys: yes, I'll try to post new findings as soon as possible.16:51.53 
henrys thank you16:52.08 
mvrhel wow the mupdf cluster run is so fast16:52.46 
Robin_Watts mvrhel: Looking at your latest bmpcmp (I'm nosey) there look to be lots of files where the candidate and reference bitmaps look identical, but the diff shows lots of differences.16:53.12 
  Those are presumably differences in spot planes. But I would have hoped that that should show up in the candidate/reference bitmaps too, as I now map the spots down.16:53.48 
mvrhel Robin_Watts: which one are you looking at?16:54.12 
Robin_Watts Look at the top of page 2 for example16:54.18 
  Number 12.16:54.31 
henrys tor8:I assume you know about the new meeting time with paulgardiner, we changed this while you weren't here and hope it is okay with you.16:54.32 
mvrhel well those are halftoned16:55.23 
tor8 what new meeting time?16:55.33 
  what's the new meeting time?16:55.39 
mvrhel the levels are slightly different so the screen level is different Robin_Watts16:55.48 
  making for the -t 5 not to really help16:55.56 
  in filtering them out16:56.12 
Robin_Watts Right, but I'd have expected to see the difference in the blink test.16:56.27 
mvrhel blink test?16:56.43 
henrys tor8:that leads me to guess you haven't read paulgardiner's status report - it came out this morning to tech - but ... Friday 9:00 PST16:56.45 
Robin_Watts mvrhel: Roll the pointer into and out of the left hand image, and the left hand and middle images swap.16:57.06 
mvrhel oh16:57.24 
  let me try that16:57.32 
Robin_Watts Let me try and find another example.16:57.33 
marcosw bugzilla has recovered from not being able to write to the directory. The strange thing is that it didn't work when I first tried it after reboot but now it's okay.16:57.42 
Robin_Watts On the same page, number 20.16:57.54 
henrys so does BST and GMT not and they are the same geographical area, is that how it works?16:58.13 
Robin_Watts marcosw: Maybe it tries on a timer, and you were seeing a 'cached' message ?16:58.14 
henrys does BST have Daylight savings time and GMT not ...16:58.38 
Robin_Watts GMT is fixed. BST changes with daylight. Same geographical areas.16:58.45 
marcosw Robin_Watts: probably, but still odd.16:58.48 
Robin_Watts BST = British Summer Time. GMT = Greenwich Mean Time.16:59.08 
  BST is the fault of those pesky scots :)16:59.26 
henrys oh my S for summer and not Standard. very confusing.16:59.52 
Robin_Watts mvrhel: Do you see the blink effect with number 20 ?17:00.30 
mvrhel yes17:01.29 
  I will take a look at that one real quick17:03.12 
  rather interesting17:03.17 
Robin_Watts I'm not suggesting this is a problem with your code.17:03.28 
mvrhel I am curious what the diff is17:03.52 
  the top of page 2 (number 29) is interesting17:04.14 
  that is actually a progression17:04.19 
Robin_Watts The thing that concerns me, is that if there is a change in the spots, we should see a change in the candidate and reference bitmaps that bmpcmp is producing.17:05.44 
  and we don't.17:05.46 
mvrhel looking at 34, I think the new code is correct17:05.47 
  Robin_Watts: I dont think those files have spots17:06.04 
  let me show you one that does have spots17:06.21 
  let the current bmpcmp finish17:06.37 
Robin_Watts 34 is down to clist instability.17:06.39 
mvrhel hehe. Robin_Watts17:09.22 
  look at the new ones now17:09.27 
  first page17:09.29 
  number 2017:09.31 
  the source files are wrong17:10.17 
  23 is the same way17:10.44 
vtorri and 42 ?17:10.45 
Robin_Watts mvrhel: Shift reload :)17:11.04 
  Your browsers cache is confused.17:11.13 
mvrhel ah ok17:11.18 
Robin_Watts (I just had the same experience :) )17:11.30 
mvrhel ok fixed17:11.44 
Robin_Watts You're comparing planar cmyk to non planar pamcmyk here?17:12.35 
mvrhel planar psdcmyk to non planar psdcmyk17:12.59 
Robin_Watts When you use the planar device, the clist buffer sizes work out slightly differently (and you get +/- 1 line in the bandheight sometimes)17:13.06 
mvrhel why does it put all the no diff detected in here now17:13.12 
  ah ok17:13.23 
Robin_Watts This can cause different things to go into different bands, hence 1 pixel rounding differences.17:13.37 
  mvrhel: Because that was requested :)17:13.48 
mvrhel by whom17:13.55 
Robin_Watts marcosw. The same code that does that does the 'I couldn't compare the two files because the number of spots changed" stuff.17:14.57 
  Number 41, top of page 2 has some dropouts in the text that's really images.17:16.26 
  Gradients look noticably smoother though.17:18.03 
  (Number 58, page 2 for example)17:18.25 
  Let me remove the ones that just say "bmpcmp: No differences detected"17:19.51 
henrys mvrhel:2000 lines wow...17:20.57 
mvrhel Robin_Watts: that would be good17:22.39 
  henrys: that was a guesstimate by me looking at what git was showing was added 17:23.41 
  Robin_Watts: so number 740 on page 4 (starting from page 0) has diff in spots17:24.35 
  the compare is wacky but it drew my attention17:24.56 
Robin_Watts ok. so we do see a difference in the bmpcmp results.17:25.46 
mvrhel yes17:25.55 
Robin_Watts Are the bmpcmp images a true reflection of the output ?17:26.14 
mvrhel 862 on page 6 is troubling17:26.20 
  I am not seeing this come out this way locally17:26.29 
  I will take another look at it 17:26.38 
ray_laptop mvrhel: can you look at the comment I just added to http://bugs.ghostscript.com/show_bug.cgi?id=689805 (you aren't on the CC list and I don't know if you get the gs-bugs email)17:26.45 
Robin_Watts bmpcmp: We only support v1 psd files! 17:26.50 
  That's an error message we shouldn't be getting.17:27.05 
ray_laptop bbiab17:27.15 
Robin_Watts It suggests that bmpcmp is reading the file wrong.17:27.19 
mvrhel oh yes17:27.39 
Robin_Watts mvrhel: Could you generate me the psdcmyk output with your new code for that please?17:27.47 
  (the cluster will have lost it by now)17:27.54 
mvrhel Robin_Watts: which number is this?17:28.05 
Robin_Watts 74017:28.10 
  tests_private/comparefiles/Bug688584.ps.psdcmyk.300.117:28.18 
  741 is similarly broken.17:28.45 
mvrhel oh yes17:28.50 
  ok17:28.51 
Robin_Watts (Again, to be clear, this is bmpcmp broken, not your code)17:29.16 
mvrhel well maybe not17:29.22 
  let me make sure the file is ok 17:29.32 
  we do max out on our allowed spot colors in this file17:30.50 
  ok there *is* an issue with the output when I add the %d to the file name to get multiple pages17:31.27 
  hehe and the single page one is wacked17:32.25 
  sigh17:32.31 
  very strange17:32.44 
  so Robin_Watts: this is my problem17:32.53 
Robin_Watts oh, fair enough :)17:33.44 
mvrhel let me look at rays comment then I am going to dig into this17:33.47 
Robin_Watts IF you find that bmpcmp is giving you any such error messages in future, please let me know.17:34.13 
mvrhel ok will do17:34.46 
  this thing is majorly confused since it only has 1 spot color17:38.53 
  I bet there is some screwy PS stuff going on here17:39.08 
ray_laptop oops. I wanted to see the bmpcmp output from my last run of gitpush.sh gs -- but I did gitpush.sh gs bmpcmp and it put two jobs in17:54.49 
  if I kill the 'gs' run, will it confuse the bmpcmp behind it ?17:55.20 
  oh, well. it doesn't take that long to run just 'gs'17:55.58 
Robin_Watts ray_laptop: Yes, almost certainly.17:56.07 
ray_laptop Robin_Watts: thanks -- that's what I figured17:57.07 
Robin_Watts tor8: So, familiar refrain: What do we need to do before releasing MuPDF 1.0 ?18:01.43 
mvrhel bbiaw off to lunch. 18:06.32 
ray_laptop hmm... must be some indeterminisms -- my initial 'gs' run showed 7 diffs -- this time I only got 4 :-(18:24.26 
  and bmpcmp shows "no differences detected" on all 4 :-(18:26.06 
tor8 Robin_Watts: I don't know.19:01.12 
Robin_Watts We should figure that out.19:01.30 
  Our tasks from the last meeting were "Get MuPDF 1.0 out", so it'd be good to go to the next meeting with that done :)19:01.53 
tor8 henrys: huh? friday night? that's ... not good ... not for a regular thing.19:02.03 
  was there some problem with tuesdays after the regular meeting?19:02.28 
Robin_Watts tor8: Tuesdays aren't great for Paul.19:02.38 
tor8 Robin_Watts: agreed :)19:02.41 
Robin_Watts But if fridays are particularly painful for you, he said he'd cope with tuesdays.19:03.06 
tor8 friday night is regular gaming night with friends...19:03.29 
  what other days are good for paul?19:03.42 
Robin_Watts I know he has a regular engagement tuesday evenings (and maybe thursdays too)19:04.04 
  We could do *before* the regular meeting on tuesdays maybe?19:04.21 
  I'd not be averse to kicking 1.0 out the door as is now.19:05.17 
tor8 fridays so that we finish by 5 or at latest 6pm CE(S)T will work, or earlier on tuesdays19:05.19 
  Robin_Watts: right. did we fix the main build issues that were reported?19:05.33 
Robin_Watts tor8: Which were?19:05.46 
  "Didn't build on Android" turned out to be "The reporter is a muppet"19:06.09 
tor8 Robin_Watts: something about a broken vs2005 build?19:06.11 
Robin_Watts Ah, right, yes. I need to talk to you about that.19:06.29 
tor8 oh, right. the usual android bug reports :) at least one email a week from someone who hasn't installed the thirdparty package.19:06.37 
  Robin_Watts: we could strip out the 256x256 icon variant if that makes it easier19:06.56 
Robin_Watts You added a new .ico file that contains a windows vista style image (256x256 png).19:06.57 
  That kills VS2005.19:07.06 
tor8 ototh, 2005 is getting ancient :)19:07.12 
Robin_Watts I'd personally rather lose the 256x256 image than lose VS2005 compatibilty.19:07.24 
tor8 then let's drop the 256x256 image19:07.34 
Robin_Watts Can you do that? I don't have an .ico editor immediately to hand.19:07.55 
tor8 I use gimp for ico editing :)19:08.08 
Robin_Watts It wasn't so much thirdparty being missing as "I've cocked up EVERYTHING about my android install", I think.19:08.36 
tor8 yeah, that particular one did seem a bit like "my environment is FUBAR and I don't know it"19:09.05 
Robin_Watts oh, right, I was going to look at bug 692924.19:09.49 
  I was going to change the logic in the loop there to treat anything that didn't look like a page range specifier as a filename.19:10.20 
  When you disabled the link following button in mupdf did you mean to completely disable link following?19:11.23 
tor8 Robin_Watts: yes, to match what iOS does. unintentionally following invisible links by tapping on the page is awkward; I want a better way to interact with the links.19:12.32 
Robin_Watts ok. Matching ios seems fair enough.19:12.54 
tor8 we can experiment with the link UI after 1.0 was my intention19:13.01 
Robin_Watts sure.19:13.07 
tor8 so revert that particular commit right after 1.0 :)19:13.12 
Robin_Watts so I'd like to sort 692924, but other than that I think I'm happy to release.19:13.29 
tor8 I have pushed an icon fix; can you double check that it works with VS2005?19:13.30 
Robin_Watts Will do.19:13.36 
tor8 right. seems fair to me. I rebased and pushed the fixes I had sitting on the 'unstable' branch.19:14.07 
  so I think we're in decent shape to tag 1.019:14.24 
Robin_Watts I still get an error with mupdf.ico19:14.55 
  where did you push to?19:15.10 
  hmm. I did pull in your commit...19:15.26 
  so why isn't this working?19:15.52 
  Is that really a .ico ?19:17.46 
  I'm a tool. Ignore me.19:28.30 
  Yes, that builds fine now.19:30.20 
  tor8: Would you object to me removing the '.pdf' check in fz_open_document and moving the pdf case to the end?19:41.59 
  i.e. any file that doesn't match .cbz and .xps would be assumed to be a pdf ?19:42.17 
  I've pushed that fix as I think you suggested exactly that the other day. Revert it if you dare^H^H^Hisagree.19:48.16 
tor8 Robin_Watts: no objection.19:55.38 
Robin_Watts cool.19:55.46 
tor8 Robin_Watts: heading to bed now, still jet lagged. ttytm.19:56.42 
Robin_Watts Night.19:56.53
