Re: [CentOS] OT? File order on CentOS/Samba server -- SOLVED (kind of...)
Hi, You might want to try to look into the Distiller side of things. That's what I always did. I am a DTP guy. 1) I believe you are using Rundirex.txt file to convert all the .ps's into one .pdf. This page from Adobe confirms that it will take the files in directory order under Windows: http://kb.adobe.com/selfservice/viewContent.do?externalId=318674 -- Acrobat Distiller for Windows will process the files in the order in which you put them into the folder and create the PDF pages in the order in which it processes the files. -- Acrobat Distiller for Mac OS will process the files in alphabetical order. (one solution would be getting a mac, hehehe). Strange that you never hit the wrong order problem before, since according to that page, you should... Regardless of what that paper says, Distiller has ALWAYS processed the files in alphabetical order under Windows. I have been doing so since 2000 and Acrobat Distiller 4. We are now at 9. I refer, of course, to the use of rundirx. 2) That page also talks about Runfilex.ps file, which is basically the same, only you have to list each .ps file in the order you want them to be included. I already addressed that on my first post. I tried runfilex.ps but then Distiller takes 30 to 40 minutes to do the same job that it now does in 3 to 4 minutes, which really is not an option for a newspaper at closing time. I will do some more experiences, from the Distiller side and the Linux side, and I will report here.

if this distiller process is being run from a DOS batch job in

Re: [CentOS] OT? File order on CentOS/Samba server
You don't necessarily have to wait to see what the Distiller would do. ls -U shows the files unsorted, in the directory order, that is probably the order in which the Distiller is using them. Yes, Distiller uses the directory order. I made an experience at home. I copied 10 files by hand, one by one, from Windows to a CentOS machine. Copy order F08C.ps F06C.ps F03C.ps F05C.ps F10C.ps F02C.ps F07C.ps F04C.ps F01C.ps F09C.ps I obtained the following results. EXT3 inode numbers (manually sorted here) match the copy order --- 6998658 F08C.ps 6998659 F06C.ps 6998660 F03C.ps 6998661 F05C.ps 6998662 F10C.ps 6998663 F02C.ps 6998664 F07C.ps 6998665 F04C.ps 6998666 F01C.ps 6998667 F09C.ps EXT3 Directory Order (ls -U1) F04C.ps F02C.ps F03C.ps F05C.ps F09C.ps F08C.ps F10C.ps F07C.ps F01C.ps F06C.ps Distiller Order matches Directory order - F04C.ps F02C.ps F03C.ps F05C.ps F09C.ps F08C.ps F10C.ps F07C.ps F01C.ps F06C.ps I see that the directory order does not match the inode order (which is the same as the copy order). Would this be due to the current asynchronous nature of filesystem operations? Let's try that: I will now reboot the server machine with the sync option on filesystem mount. ... Rebooted with sync on that filesystem. Copied the files again to a newly created dir, etc. The results are the same. Why doesn't the directory order reflect the inode order? Time for further study.

This solution is even better than the initial situation: since we can now predict the order in which the pages will be processed, we can manipulate the order at will by doing multi-phased copies to the folder, in any order we want, instead of being limited to the alphanumeric one provided by NTFS :-) So dir_index ON (and my ignorance of the inner workings of EXT3) was to blame for this confusion, from the beginning!

If you use a shell script with a wildcard to do the move, the shell will sort the list on the command line as it expands it, so the names are linked into the new directory in sorted order.

Re: [CentOS] OT? File order on CentOS/Samba server -- SOLVED (kind of...)
Did you consider sharing a directory from the machine running distiller and cifs-mounting it on the linux side to get ntfs behavior? That is out of question. The Windows machines are graphic workstations which are not all connected all the time and the Distiller service is essential to the network. Also, I'm curious about the timing of the runs. It doesn't sound like the file operations are grouped atomically. How do you ensure that the whole set is present when distiller starts, or that only one set is present? This is a very peculiar implementation. As I said om my first post, we are a newspaper and, as all newspapers, we don't have a fixed time to close the edition. It closes when it is ready, that's all. The PDFs for print are automatically produced one by one from PostScript files. The PS files fall on a folder watched by Acrobat Distiller and after being stable for more than 10 seconds the conversion begins. Each one contains only one page, which will then be joined to others to form a plan for a platesetter. When all the pages have been produced, one of the graphics people places a special text file on a folder watched by Distiller and it begins to bulk process all the individual PS files: downsampling images, converting the color space to sRGB, consolidating font subsets, creating bookmarks and indexes, etc. The result is a multipage PDF for electronic distribution, containing the whole newspaper in the sRGB color space. This always worked flawlessly until some days ago I replaced the win2k server with a new CentOS/Samba one.

Re: [CentOS] OT? File order on CentOS/Samba server -- SOLVED (kind of...)
I was under the impression that the Distiller app was running under Windows. If it isn't, it doesn't make much sense for it to expect NTFS filesystem semantics. Yes, Distiller is running under Windows. When pages start to get ready, one of the graphic operators opens Distiller on his/her workstation which then starts watching a folder *on the server*. Can't the trigger operation of placing the special text file be replaced by that person starting the script instead (perhaps click a button on a web page or something similar)? Yes, that would be a possibility. But those people have strong rooted habits and they are not in the least technically minded. As such, I would prefer to keep a workflow that has been functioning very well. (By the way, that special text file is a snippet of PostScript code that instructs Distiller on where to find the files and how to process them. It would be needed anyway.) Perhaps this obstacle will be removed by applying the correct parameters to the EXT3 file system, as suggested by William Maltby and Steve Thompson above in this thread: mount option dir_index followed by a fsck -Df. I will try this Monday. Thank you for answering. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I don't really think so... I believe dir_index is the default, your filesystem was probably already created with the dir_index option, and yet your files are out of order. Looking at the man page, it's sorted by the hash of the filename. The purpose is not to present you the files in order, but to make it quicker to open a file in a directory with a huge number of files. Now I will have to wait for monday to do the Distiller stuff. You don't necessarily have to wait to see what the Distiller would do. ls -U shows the files unsorted, in the directory order, that is probably the order in which the Distiller is using them.

Re: [CentOS] OT? File order on CentOS/Samba server -- SOLVED (kind of...)
Hi, You might want to try to look into the Distiller side of things. 1) I believe you are using Rundirex.txt file to convert all the .ps's into one .pdf. This page from Adobe confirms that it will take the files in directory order under Windows: http://kb.adobe.com/selfservice/viewContent.do?externalId=318674 -- Acrobat Distiller for Windows will process the files in the order in which you put them into the folder and create the PDF pages in the order in which it processes the files. -- Acrobat Distiller for Mac OS will process the files in alphabetical order. (one solution would be getting a mac, hehehe). Strange that you never hit the wrong order problem before, since according to that page, you should... 2) That page also talks about Runfilex.ps file, which is basically the same, only you have to list each .ps file in the order you want them to be included. Any chance you could use this one instead of Rundirex? Is the list of included files fixed? Could the Runfilex.ps file be somehow generated on the server based on the list of files that are there (maybe by a CGI in a web interface) instead of copied by the guy? 3) From what I see, Rundirex.txt (even with a .txt extension) is a Postscript file. AFAIK, Postscript is a full programming language, I've even seen webservers written in Postscript. I'm sure there is a way to sort the list of files from inside Postscript. However, I don't know the language and wouldn't know how to do that, or even how to start looking for it. I searched on the web for someone that did implement this on Rundirex.txt specifically, but with no luck. Maybe someone else on the list will know Postscript, or you could try to look for it in a Postscript list, I'm sure the solution will exist there. Good luck! And let us know how you fixed it!

[...] way to sort the list of files from inside Postscript.
I think I did it.
Inside your Rundirex.txt, you should have this snippet:
/RunDir { % Uses PathName variable on the operand stack
{ /mysave save def % Performs a save before running the PS file
dup = flush % Shows name of PS file being run
RunFile % Calls built in Distiller procedure
clear cleardictstack % Cleans up after PS file
mysave restore% Restores save level
}
255 string
filenameforall
} def
Right? If so, then add the definition of a bubble sort routine before
that (which I got from Wikipedia), and then modify /RunDir into the
snippet below. Ghostscript has a .sort built-in that does exaclty
that, but I'm including it here as I don't know if Distiller will too.
% Bubble sort from Wikibooks page on PostScript
/mybubblesort
{ 1 index length 1 sub -1 1
{ 2 index exch 2 copy get 3 copy % arr proc arr i arr[i] arr i arr[i]
0 1 3 index 1 sub
{ 3 index 1 index get % arr proc arr i arr[i] arr
imax amax j arr[j]
2 index 1 index 10 index exec
{ % ... amax arr[j]
4 2 roll
}
if pop pop
}
for % arr proc arr i
arr[i] arr imax amax
4 -1 roll exch 4 1 roll put put
}
for
pop
} bind def
/RunDir { % Uses PathName variable on the operand stack
/nf 0 def % Reset counter for number of files
{ 255 string copy % Copy to a separate string (otherwise
would be overwritten)
/nf nf 1 add def % Increment counter of number of files
}
255 string
filenameforall
nf array astore % Put all filenames in an array
{ lt } mybubblesort % And sort it
{ /mysave save def % Performs a save before running the PS file
dup = flush % Shows name of PS file being run
RunFile % Calls built in Distiller procedure
clear cleardictstack % Cleans up after PS file
mysave restore% Restores save level
}
forall % Execute original procedure, but
using sorted array
} def
Of course I did not test it with Distiller which I don't have... I did
test the part of sorting the list of files with Ghostscript and it
works.
Maybe word wrapping in the e-mail will ruin the snippet, if that's the
case please let me know and I'll send it attached to you.
Let us know if that works!

[CentOS] OT? File order on CentOS/Samba server
I hope someone familiar with the way Linux processes files can enlighten me on the following: I recently replaced an old Windows 2000 server with a new machine running CentOS 5.2. It uses Samba 3.2.7 to serve a network of Windows XP clients. We are a newspaper. We use Acrobat Distiller to batch-convert a folder of single-page PostScript files (for print) to a multipage PDF file (for electronic distribution). Running on a workstation, Distiller watches the folder on a Samba share and does the conversion, automatically creating bookmarks, indexes and other information. On the Windows server, Distiller processes the files by filename order: M09010901A001C.ps M09010901A002C.ps M09010901A003C.ps ... and so on. On the Linux server, Distiller processes the files in an order that seems arbitrary, for example: M09010901A021C.ps M09010901A005C.ps M09010901A015C.ps ... and so on. The order Distiller uses is NOT related to the time stamp of the files. I tried to copy the files to the watched folder one by one in the correct order; the result is the same. This creates the need to open the final PDF and reshuffle the pages by hand, which is very time consuming and prone to error. There is a workaround to this: use the runfilex script that comes with Acrobat: it can contain a list of files to convert, in the order you want. Unfortunately, this is not acceptable for us since the process then takes about 40 minutes (irrespective of platform or filesystem), instead of 3 or 4 minutes. My question is: how is the order of files determined by Linux when a particular order is not explicitly required by a program? I noted the following: I have 4 files in a folder: file1.ps, file2.ps, file3.ps, file4.ps. When I order them by date, they appear in Windows Explorer in, say, the following order: 3, 4, 1, 2 If I copy them to a new folder one by one in the order 1, 2, 3, 4, they will still appear in the order 3, 4, 1, 2 when ordered by date. So, what information is transported with the files that makes the Linux server present them to the world in this order? Does someone know a workaround to this situation or can someone point me to information about file ordering with Linux? By the way, I am using the EXT3 file system. I tried the same on a VFAT file system and the result is the same. It seems to be a Linux thing, not a file system thing.
