Hi, I have had a look at libaps and I have found a couple of problems for whi= ch=20 patches are included below. The orignals are from cvs kdesupport a couple= of=20 days ago. Patches: attrcommon.patch fixes a crash when reading fonts. utils.patch corrects check for failure to open a file in CopyFileSpecial(= ). lprtransport.patch deals with two things: 1. To be able to print the test page to my printer (hl-730 via ghostscrip= t) I=20 had to a) add the input file to the gs command :) and b) supress headers = (lpr=20 -h option) which I made as a new treatment under 'case LPR_IMPL_BSD:'. I = am=20 sure this is not the best and adeqvate way to do it but at least I get th= e=20 test page out. 2. Changes the way the if-filter is treated so that no filter is added if= the=20 filter masterfile is missing. I found that if the 'if' entry exists in th= e=20 printcap file, a valid filter must exists or else nothing is printed. Question: What does the lpr -l option have to do with flagBinary? -l is listed as 'use a filter' in my man pages. ---- What's the general state of the project? Is it scheduled to be used by=20 someone (Corel for instance)? Whats the state of the QT interface? I have compiled and run it and it=20 crashes on closedown but this may be my program, it is a very quick hack. Regards, Dag=00 |

Hi all,
I could use a little help here. It may well be that
I'm doing something wrong, but I seem to have a memory
leak. I've reduced it down to a small test case, and
was hoping you could look at what I'm doing and see
the problem.
I compile the attached C program with this command
line:
gcc -g -Wall -laps aps_test.c -o prntest
Run it with a valid printer queue as the sole parameter:
./prntest lp0
Output will be the virtual memory size (from /proc) for
the process, and the difference from the previous
iteration, like this:
$ ./prntest hp4050
Total Virtual: 1712128 Change: 1712128
Total Virtual: 1716224 Change: 4096
Total Virtual: 1720320 Change: 4096
Total Virtual: 1724416 Change: 4096
Total Virtual: 1724416 Change: 0
Total Virtual: 1728512 Change: 4096
Total Virtual: 1728512 Change: 0
Total Virtual: 1732608 Change: 4096
Total Virtual: 1736704 Change: 4096
Total Virtual: 1736704 Change: 0
Total Virtual: 1740800 Change: 4096
Total Virtual: 1740800 Change: 0
....
This example was from a queue that had six jobs.
Because I'm getting info out of the /proc file system,
this will need to be run under Linux.
I've noticed that it leaks memory faster the more
items are in the queue.
Thanks in advance for any help you can give me.
Please let me know if I'm doing something stupid
in the code.
The code is appended to the end of this message.

Hi Michael, I've had a look at the project you've been working on, and it is very interesting. I can certainly see how SysAPS would fit well into what you're doing, as both projects need to solve some of the same problems. You're right that the CUPS support currently in SysAPS is fairly minimal; we began implementing a CUPS-specific transport, but it hasn't come very far at all yet. We'd certainly welcome any collaboration you'd like to do in this area. We've also been experimenting with a Qt-based print dialog box to sit ontop of CUPS. I like a lot of what is planned / in progress for the KDE Print dialog box, and see the potential to combine the best ideas of both into a single dialog box. I've attached screen grabs of what we have so far. The basic idea is to provide a tabbed dialog box that can easily be added to for application or context specific pages. The "Page Settings" and "Options" pages contain settings that a user / sysadmin could potentially set as defaults for future jobs. The idea is that these same pages could also appear in Control Center. The "Page Settings" page contains a fixed set of job attributes that are commonly available from a wide range of printers. The "Options" page contains a list of all available job attributes. The idea here is to have a dynamic UI that can display attributes from PPD files or other sources without requiring the UI to be programmed to know about these attributes ahead of time. All of this code is now in the CVS repository at libaps.sourceforge.net. I should also mention that I will be travelling for a month, and most likely out of reach of email. In my absence, you should direction any questions or discussions about the SysAPS project to the mailing list at lib...@li.... There will be other people here at Corel involved in the project monitoring the mailing list, and this discussion should be able to continue in my absence. Brian Pirie |

Hiya,
Some portability patches by Michael Matz <ma...@if...> from KDE cvs.
Split into two seperate patches.
Cheers,
Waldo
revision 1.4
date: 2000/07/19 00:49:13; author: matz; state: Exp; lines: +7 -4
trying to substitute corels (is that the author?) abominations of advanced
shell substitutions with sed calls
(like ${value%%:*} with sed -e 's/:.*$//' )
----------------------------
revision 1.3
date: 2000/06/26 17:45:58; author: matz; state: Exp; lines: +46 -46
Arg. How good, that I have a strong stomach. This was full of
bla=`expr BLA ...` where BLA was supposed to be an environment var.

Yes, well, maybe :-) The other option is to have "KPrinter" and have let's say "KPrinterConfig" which inherits "KPrinter". And then "KPrinter" just provides read-access to the printer attributes and with KPrinterConfig you can change them as well. The latter would only be needed by the yet to be made "configure printer" dialog. > Seems like no piece of sysAPS should stay i the > KPrinter API - so all sysAPS related things will be accessed via KPrinter > methods, right?

Well, I don't have a clear idea about how to do everything yet. It's basically just playing around and then see how things fit in. Just some random thoughts: 1) If possible, I would like to load libaps and all printer stuff on demand only. I am not sure if that is feasible or whether that makes actual sense, but on first sight it makes sense I guess. Anyway, that means that the API should not contain direct references to libaps. No idea if this turns out to be a silly idea. 2) Does libaps report paper-sizes to you? I get error-code 6. I have added code to default to a default list of paper-size in this case, but would like to use the paper-sizes reported by libaps. Any thoughts on this? Or am I supposed to configure the paper-sizes first with the yet-non-existing printer configuration dialog? :-] Cheers, Waldo -- Make way, KDE/Linux is coming to a desktop near you! |

Hiya,
api.html contains:
3.7.4.12 Aps_AttrQuickGetPageSizeOptions()
Obtains a list of available pre-defined pages sizes.
Aps_Result Aps_AttrQuickGetAvailPageSizeOptions(
Aps_JobAttrHandle jobAttributes,
Aps_PageSize ***pageSizes,
int *numPageSizes);
Aps_AttrQuickGetAvailPageSizeOptions should be Aps_AttrQuickGetPageSizeOptions
Cheers,
Waldo

Hiya, attached is a patch for compiling libaps with builddir != sourcedir. Patch by David Faure <fa...@kd...> Would it be somehow possible to install libaps without installing to /etc?

Can you give me more > information on what this character set is, and what alternatives we could > potentially specify? The idea is that there are more characters than defined by ASCII and that there are even more characters as fit in a single byte. A character encoding defines a way to map a set of characters to byte-values. The most simple ones are those that map a single character to a single byte-value. Examples of such encodings are ASCII, latin-1, latin-2, etc. It is obvious that such an encoding can never define more than 256 characters. It is equally obvious that there are characters which have a byte-value defined in one encoding, but not in another encoding. Since this started to become a bit of a mess, people invented unicode. unicode defines a lot of characters and gives them all a unique value. Typically they gave them a value that fits in 16 bits. Since a lot of computer programs think of text as sequences of bytes (char) an encoding mechanism has been introduced that encodes these 16-bit unicode values into one or more(!) bytes in a sort of clever way, this is called utf8. If you have characters in a certain encoding it is always possible to convert them to unicode. E.g. you can translate every latin1 string to a corresponding unicode string. The other way around is not true, a unicode string might contain characters that don't have a representation in latin1. With utf8 you do not have this problem. Unfortunately not everyone today uses utf8, some still use e.g. latin1 (because if you only write english texts you don't really need these other characters much). A users "locale" defines which encoding this user typically uses e.g. for filenames and such. Assuming that you don't want to discriminate anyone who happens to use a certain range of characters the options for defining a encoding in an interface are basically limited to "utf8" because it can represent every possible character, or "the encoding specified in the locale" since that is the one that the user has choosen. Note that the user could have chosen to use utf8 in his locale. E.g. all filenames are typically encoded with "the encoding specified in the locale". The problem of using "the encoding specified in the locale" is that the string might originate from another system/other user which might have another locale and that you then have to convert this to the locale in use by this user and in such a conversion you might loose information. For a more accurate description of this topic see http://www.unicode.org. Cheers, Waldo -- Make way, KDE/Linux is coming to a desktop near you! |

RFC: Printing in KDE 2.0
========================
Date: May 22, 2000
Author: Waldo Bastian
Printing support in KDE has not been changed since KDE 1.1.2. As such
it is not completely up to spec with the rest of KDE 2.0. In this document
a printing architecture for KDE 2.0 is proposed.
Requirements
============
Four different desired printing related abilities can be identified
within KDE:
1) The ability of a user to select a printer from the list of installed
printers to be used for a print request and to select, possibly
application specific, options for the print request.
2) The ability of a user to be notified of the status of his outstanding
print requests and the ability for the user to cancel outstanding print
requests.
3) The ability of an application to query the properties of the printer
used for a certain print request as well as options specified by the user
for this specific print request.
4) The ability of a user to add and configure a printer.
Status in KDE 1.1.2
===================
Ad 1) QPrintDialog provides this functionality in KDE 1.1.2. The drawbacks
are that this dialog does not fit in well with the KDE translation meachanism
and that it is not possible to add application specific options to this
dialog.
Ad 2) In KDE 1.1.2 applications exists which provide this functionality. The
user has to start these applications explicitly. There is no integration
with the application that issued the print-request.
Ad 3) The QPrinter class provides basic information about the printer and
the specific print request, mostly based on information supplied by the user.
Ad 4) KDE 1.1.2 provides no way to do this.
Proposed KDE 2.0 printing architecture
======================================
I suggest to adopt sysAPS as API to access the operating systems printing
system, e.g. CUPS or LPR:
KDE -> sysAPS -> IPP -> CUPS -> filters -> driver -> backend
-> LPR -> filters -> driver -> backend
Other printing systems can be supported by adding support for them to sysAPS.
To quote the sysAPS homepage:
"This project, driven by Corel, provides a unified API for accessing
printing-specific services outside the realm of the graphics API. This
includes querying & controlling features of a given printer model, sending
jobs, accessing queues and configuration."
sysAPS is under LGPL, is written in C and has both a C as well as an optional
C++ API. It is a rather young project so it should not be a problem to adapt
to any specific wishes in the API. You can find them at
http://sourceforge.net/project/?group_id=2328.
Based on sysAPS it will be relatively straightforward to meet KDEs printing
requirements:
1) A KPrintDialog based on KDIalogBase should be made. It can use sysAPS
to query for available printers and enable/disable available options
based on the capabilities of the selected printer.
2) A notification/control interface should be made for printing job-control.
sysAPS seems to provide all necassery functionality. We only need to provide
the UI. Maybe this can be part of kio_uiserver. Maybe it should be made a
seperate application.
3) For now the QPrinter class seems to be adequate. It might be desirable to
embed this class in a KPrinter class to make it possible to add KDE wide
options not provided by Qt. In addition this class could give access to
a printer's PPD file allowing applications to fine tune their print output.
4) A kcontrol module should be written which allows printer configuration.
sysAPI seems to provided al necassery functionality. Only the GUI part needs
to be added.
Considerations
==============
*) The proposed printing architecture is not limited to Postscript output,
although that is what the Qt printing classes produce.
*) The proposed sysAPS library can be used by non-KDE applications, including
command line tools. Although the GNOME project is not interested in
cooperation in this area, there are no compelling technical reasons which
prevent them from adopting sysAPS, now or in the future.

Coincidentally, this is something that I've been working on today. The heuristic that I'm using is, when a printcap entry has multiple alias names, to prefer the first one that contains a space character as the primary name for that printer. Do you think this rule of thumb will cover most situations? The alternative that I thought of was to select the longest of the names. > Slightly related, all strings are represented as "const char *".

Hiya, I'm working on migrating KDE 2.x to a APS based printing solution. As such I have added v1.0 of libaps to kdesupport. Since it needs to write to /etc it needs to be root so I haven't made it install by default. So you need to pass --with-aps when configuring kdesupport. I also started looking at a simple print dialog based on libAPS and one of the first things that I noted was that, using LPR as spooler, the names of the printers are a bit cryptic. E.g. with a printcap entry like: lp|ap|arpa|ucbarpa|LA-180 DecWriter III:\ I get "ap" as name. I rather would be able to show "LA-180 DecWriter III" to the user. Slightly related, all strings are represented as "const char *". Assuming that in some cases these strings are user defined it would be usefull to define in the API what the character encoding of such a string is supposed to be. utf8 seems a good candidate to me.

Stephan, This is a very good point! If you dig into the code, you'll see that there is already a certain amount of support implemented for this, but it needs to be made accessible at the API level via a simple function. Internally, LprJobDispatch() passes on the document title via the docTitle member of Aps_QuickJobInfo. The new API function would just need to provide a means of setting this Aps_QuickJobInfo structure member in a particular job.

Subject: Idea for attributes -- Comparing / Calculating difference
Date: Tuesday, March 07, 2000 1:35 am
Hello,
I was just thinking that it would be useful to be able to perform a few
special operations on Job attributes to increase efficiency and perhaps
improve functionality as well. Things of this nature could be useful for
doing things like selective updating, or marking settings which differ from
defaults in a UI, or assist in logging or debugging by indicating
explicitely what has changed from one run to another.
Brian: Since this is your baby, what do you think?
[Loosly C-style pseudo-code]
/* Compare a setting between attr1 and attr2 */
Aps_Result Aps_AttrCompare(Aps_JobAttrHandle attr1, Aps_JobAttrHandle attr2,
const char *attributeID, int *equal) {
if ((attr1 has attributeID) && (attr2 has attributeID)) {
*equal = (attr1.attributeID == attr2.attributeID);
return APS_SUCCESS;
} else {
*equal = FALSE;
return APS_NOT_FOUND;
}
}
/* Report settings in attr1 that are not in attr2 or different from those in
attr2 */
/* ie. attr2 is reference copy and attr1 is local storage */
/* N.B. target not created if no diffs... */
Aps_Result Aps_AttrDiffAll(Aps_JobAttrHandle attr1, Aps_JobAttrHandle attr2,
Apr_JobAttrHandle *target) {
foreach(attributeID in attr1) {
int equal;
if (APS_NOT_FOUND == Aps_AttrCompare(attr1, attr2, attributeID, &
equal) || (equal)) {
if (! *target) *target = new Aps_JobAttrHandle;
Aps_AttrSetSetting(*targer, attributeID, attr1);
}
}
return APS_SUCCESS;
}
/* Update settings which differ from attr1 to attr2 into attr2 */
/* ie. attr2 is reference copy and attr1 is local storage */
Aps_Result Aps_AttrUpdateAll(Aps_JobAttrHandle attr1, Aps_JobAttrHandle
attr2) {
return Aps_AttrDiffAll(attr1, attr2, attr2);
}
/* Enumerate attributes through a callback */
Aps_Result Aps_AttrEnumerate(Aps_JobAttrHandle attr, int
(*enumfunc)(Aps_JobAttrHandle, const char *attributeID)) {

From: "Jeff Brown" <jef...@co...> Subject: Identification of object types Date: Wednesday, February 09, 2000 5:22 pm APS needs a mechanism for providing the application with the type of an object given its handle. This could be used if the application caches objects aggressively and needs to find out what they are. Alternately, it could be used to protect filter functions from being applied to the wrong type of object. Note, the problem with filters applies only to those created as callbacks by the application. APS handles internally checks the target object type before applying a filter. Jeff Brown (x5625). |

Subject: Common printer configuration storage
Date: Friday, February 18, 2000 5:29 pm
Hello everyone,
Since a significant part of the new APS involves installation and
configuration of printers, it makes sense for these things to become
externally visible to the system in some pre-defined standard way. However
this is a non-trivial matter as APS must be made to communicate with MANY
different potential underlying transports. Therefore APS may need to
provide information in many different forms to satisfy each...
... or it may not. It may simply write out configuration information in
some standard form to a directory under /etc/. That way all of the
information is available, not just the subset that may or may not be
understood by a given transport. This also gives us a great place to store
any configuration elements that would be processed by APS internally (like
translations of various types, header page creation, accounting and logging,
etc...)
Assuming APS gets a common repository for printer configuration information,
then what?
Well... should APS be told to use that information exclusively, or should
the user be able to indicate that he/she wants APS to be "friendly" to some
other installed print system. This brings about several possible
behaviours:
1. APS uses its internal records exclusively and verifies/regenerates
configuration files for subordinate transports
2. APS stores everything it knows in its internal records but allows the
user to choose one of the following:
a. work blindly (do not verify external configuration files)
b. check for inconsistencies, and import any differences
c. check for inconsistencies, and report any differences
d. as with 'c' but grant the user the option of importing differences,
ignoring them, or obliterating them.
As for why this is necessary, consider the case of the print filters.
For LPR, APS knows many things the transport does not, and could not ever
hope to know, namely, what KIND of printer is attached, and HOW to
communicate with it (what driver). APS therefore needs to get in the middle
somehow and either intercept traffic before it enters the transport, or
after it exits but before it reaches the printer. The most flexible option
is to intercept traffic just before it gets sent to the printer, and
thankfully, this is a simple task: you just set up a print filter.
Under LPR (and in most other cases), the transport receives data blindly...
eg. in some arbitrary format. It does not may any attempt to format it for
the printer, nor should it, as its sole purpose is to pass what it receives
down the pipe. For the user's benefit, however, APS has to get in there and
make sure that all it well and that you're not trying to do anything stupid
like print postscript to a non-postscript printer, or print a JPEG file
without first translating that into the a representation that the printer
can understand. APS depends on filters inserted into the output stream to
perform all of the necessary translations on behalf of the user. However
doing so requires knowledge of what kind of printer you have, what it
understands, what paper sizes it handles, how it should do colour
correction, dithering, downsampling or upsampling, and what drivers exist to
help us out.
Ideally, a filter should be provided with a single parameter: What printer
am I? It should then look up in the APS database to find out anything else
it needs. First it should pass the data through a common filter script used
by APS to convert the source data to a common representation (Postscript
seems like a good idea). Then it should use another common APS script to
perform the other required transformations. Finally it should take the
output and send it to the correct driver for printing... As this step may
vary from transport to transport, it is unwise for it to be accomplished by
a common APS script and should really be done on a per-transport basis.
Sorry... I have to run to catch a train!
Thoughts anyone?
Jeff Brown. (x5625)

Hi Jeff,
This issue is the programming work that I've been looking at recently. The
basic
mechanism is to create a per-printer configuration file, with per-user and
system-wide copies. This allows for individual user configuration of their
printing preferences without affecting other users, while also allowing the
sysadmin to do machine-wide configuration.
(I know that I haven't responded to each individual issues raised in your
posting, but I hope to talk about your ideas in more detail when I can give
this
the attention it deserves.)

Subject: Verification of named objects / components
Date: Monday, February 14, 2000 1:08 pm
Idea:
=====
Perform additional verifications of all named object / components which are
to be handled by APS. For example, check string length for maximum size and
contents for invalid characters.
Proposal:
=========
Create a set of standard functions to be used in performing validation of
names and parameters on a semi-automatic basis. Such functions would use a
constant description of the type of tests to be performed and would
adjust/modify any names as required by the implementation. The description
may be either explicit, as in a table, or implicit, by the code structure
itself, or a mixture of both.
Explicit description:
Aps_Result verifyName(const StringCharacteristics *table, const char
*inString, char *outString) {
<code uses the table to perform a series of checks then copies the input
parameter to the provided buffer>
<returns: APS_NAME_TOO_LONG (error), APS_NAME_TRUNCATED (warning),
APS_NAME_INVALID_CONTENTS (error), APS_NAME_TRANSLATED (warning),
APS_NAME_REJECTED (generic error), etc...
}
Implicit description:
Aps_Result LprPrinterVerifyName(const char *inString, char *outString)
{
<code performs checks directly and knows the special layout required by
this subsystem>
<returns as above>
}
Mixture:
Aps_Result LprPrinterVerifyName(const char *inString, char *outString)
{
<for routine checks; code uses generic functions with an explicit
description of what is being tested>
<for special checks; code performs special verifications knowing the
layout required by this subsystem>
<returns as above>
Affected areas:
===============
Any subsystems which must deal with input from the application (directly or
indirectly).
eg. Perform checks for validity of printer names
- APS may admit names with spaces and of a certain length
- Lpr does not admit names containing control characters, spaces, and may
limit name length due to constraints imposed by underlying filesystem or
server. (eg. Lpr printer names should not exceed 30 or so characters
because some daemon and client implementations use small fixed length
buffers for communication purposes)
- Direct consequence: if spaces, control chars or ':', '\', etc... are
admitted, LprAddPrinter will gladly insert an invalid entry into your
printcap file for you. LprRemovePrinter will not be able to remove the new
entry because it will not know of its existence.
eg. Check job names for control characters
- Lpr will get confused if presented with a \n in any name or title
eg. Translate document infomation
- docTitle is presented to Lpr using the "T" tag in its control files.
Again '\n' will confuse Lpr but we do not wish to fail in this case. It
would be preferable to transparently modify/encode the provided data
instead.
eg. Testing filename/pathname length
- APS deals with filenames in many areas using fixed-length buffers.
While one could assume filenames will never exceed MAX_FILENAME_LENGTH
(sp?), the code would be somewhat cleaner if this check were done
explicitely. At the same time, testing for invalid characters in filenames
may save APS some backing out if file-open fails.
eg. Asking the filesystem what it can do
- Some filesystems are not case-sensitive or have different restrictions
from elsewhere. A validation operation could ask the filesystem if it can
handle a particular filename, and fail gracefully.
Ideas anyone?
