medley PDFs missing from NoteCards HC files at files.interlisp.org

Some TEdit files of the NoteCards documentation are missing the matching PDFs the HC file generation process should make from them at files.interlisp.org. In directory {MEDLEY}/notecards/docs/user-guide-v1.2/ the following TEdit files have no matching PDFs:

03-SOFTWARE-INSTALLATION.TEDIT
04-SYSTEM-USE-ISSUES.TEDIT
05-NOTECARDS-BASICS.TEDIT
11-SYSTEM-CARDS.TEDIT
APP-Z-PROG-INTERFACE.TEDIT

Most or all PDFs are missing from {MEDLEY}/notecards/docs/user-guide-v1.2/from_envos/ and {MEDLEY}/notecards/docs/misc/from_envos/.

these are all files that failed in some way (an error or call to HELP) when run through TEdit or (for Lisp source files) have package problems.

The Notecards files might have missing image object sources, because Notecards isn't in WHEREIS.HASH for TEdit to pick up.

There may be other reasons that all need to be fixedd in the HCFILES process or perhaps some TEdit bugs.

I think the way to address these is to take the files one at a time, try to TEdit hardcopy the file, fix the problems encountered and then try again. Since many of the problems affect more than one file.

@pamoroso @rmkaplan @fghalasz The task here is to figure out why HCFILES fails on these files by seeing what errors arise when you just try to TEDIT the files and "hardcopy" to pdf or postscript.

The hcfiles-fails.txt and hcfiles.dribble files from the weekly builds are stored along with all the hcfiles-generated PDF files on files.interlisp.org. Unfortunately they are not included in the html index pages that HCFILES creates because they are not available until after HCFILES is run.

But they are available at https://files.interlisp.org/medley/loadups/hcfiles-fails.txt and https://files.interlisp.org/medley/loadups/hcfiles.dribble either in a browser or via wget.

hcfiles-fails.txt is just a selection from hcfiles.dribble of every line that ends in IL:FAIL.

I did a quick sampling and most of the issues are GETFN: HRULE.GETFN errors in IMAGEOBJs.

In one case opening the file with TEdit breaks with the error Help! Shouldn't happen:. In another I was able to use the file browser's hardcopy option to produce a PostScript file. The PostScript document has dashed boxes with an error message where the IMAGEOBs errors show up in TEdit.

I'll go through each file and report on the issues in more detail.

Opening {MEDLEY}/notecards/docs/user-guide-v1.2/03-SOFTWARE-INSTALLATION.TEDIT with (TEDIT '03-SOFTWARE-INSTALLATION.TEDIT) yields a blank TEdit window and a break window with the error:

Opening {MEDLEY}/notecards/docs/user-guide-v1.2/04-SYSTEM-USE-ISSUES.TEDIT with (TEDIT '04-SYSTEM-USE-ISSUES.TEDIT)displays the document with errors like this in some IMAGEOBJs:

Error in IMAGEOBJ
GETFN: HRULE.GETFN

The document has other rendering issues such as black boxes and random ideographic characters like in this screenshot:

ncdocs-tedit-error

Using the mouse wheel to scroll down the document yields a break window with the error:

In CL::%%NOT-NONCOMPLEX-NUMBER-ERROR
NIL is not a NUMBER.

Exiting the break with ^ and scrolling down some more sometimes yields the same break window.

Using the scroll bar to scroll yields a break window with the same error but a different stacktrace.

Using the Hardcopy > To a file option of the TEdit window's right-click menu yields a break window with the same error but a different stacktrace. However, a PostScript file is still produced and it renders similarly to the document in the TEdit window.

That looks like an xccs encoding issue- it thinks the font name is not in charset 0. This is one for @rmkaplan

Sep 23 '24 16:09 nbriggs

This one fails also in the Venue sysout, albeit with a different kind of error. But there the image object getfns don’t load automatically, and maybe were not included in the basic loadup. So I’ll have to poke a little more before I can say that the file itself is smashed

if you load the image object GETFN manually, does it still fail in the Venue sysout?

Sep 23 '24 16:09 masinter

The HRULE getfn is already there, although it is hard to say that that is what it is really looking for. In the venue sysout the failure shows up as trying to get the UNKNOWNGETFN proper of a NIL image object, in my current code it shows up as a font problem with a message that it failed in HRULE.GETFN (but that message may be the result of an earlier problem).

This doesn’t give an error in the Venue sysout, but the file shows up as mostly black bars after the first half page.

With current code, this is not recognized as a Tedit format file, something wrong with the trailer. So Tedit tries to read it as a plaintext file,and runs into long 255 sequences, which the XCCS format doesn’t like.

Opening {MEDLEY}/notecards/docs/user-guide-v1.2/APP-Z-PROG-INTERFACE.TEDIT with (TEDIT 'APP-Z-PROG-INTERFACE.TEDIT), the last file with issues in the user-guide-v1.2 directory, displays the document in TEdit. However, the document contains GETFN: HRULE.GETFN errors in a dozen IMAGEOBJs. Using the Hardcopy > To a file option of the TEdit window's right-click menu produces a PostScript file with the errors rendered the same way.

Sep 24 '24 11:09 pamoroso

Note that these all fail in the Venuesysout, but not always in the same way.

Nov 27 '24 20:11 rmkaplan

Based on our discussion and experiments today, I looked at some of the HCFILES failures in notecards/library/. For ones that wouldn't open in the display, I swapped the CR and LF bytes, and if I then got a font-not-found for size 13, I advised fontcreate in Tedit to substitute 10 for 13 when it read the font.

This helped with some of the files (progress), but others still failed, but now in different ways. I also noticed when I scrolled to the bottom of some of the recovered files that there was sometimes a little garbling there. In some cases the last few characters didn't show on the display, in other cases there were a few black boxes at the end. It appears that here are some 0 bytes that are being included in the last piece (maybe 3?).

Also playing around, one of the other HCFILES failures (I now forget which) was failing not in Tedit, but in the RENAMEFILE that was copying the temporary pdf file back to its place in the Medley file system. This was way down in COPYCHARS, where it was trying to read a character with the ANY eol convention (which we have talked about separately). But I'm not sure why RENAMEFILE in this context (or any context) doesn't use COPYBYTES. Is that because it is copying from {UNIX} to {DSK} ?

Dec 10 '24 07:12 rmkaplan

I opened a separate issue on the renaming problem #1900

Dec 10 '24 17:12 rmkaplan

Apart from the fact that a rename shouldn't be necessary, I think I see why the COPYCHARS hit the low-level error. It appears to think that both the newly-created tmp pdf file and the destination in {DSK} are XCCS files, so it is trying to read characters as XCCS encoded. But there appear to be 255's strewn around the pdf in unholy ways, the XCCS INCCODE function doesn't quite know what to do, and it loses track of the byte count. The Unix PS-to-PDF utilities traffic only in utf8/unicode files, but RENAMEFILE doesn't know that--the external format can be specified at OPEN, but currently not through the generic RENAMEFILE function.

RENAMEFILE could be extended to take some optional parameters, like OPEN. But a more immediate fix may be to figure out why GETFILEINFO is saying that PDF files are TEXT.

Dec 10 '24 18:12 rmkaplan

It seems that the TYPE of both PS and PDF files is coming from the entry on DEFAULTFILETYPELIST, which says that they are text. Should those be changed to BINARY? That would turn off the attempted character conversions between file devices.

Dec 10 '24 18:12 rmkaplan

I think they should both be BINARY. PDF is for sure, PS may be text, but you can't guarantee that there isn't, say, a binary blob somewhere in there.

Dec 10 '24 19:12 nbriggs

If the FDEVs for the source and destination of the rename operation are different then it is implemented via \GENERIC.RENAMEFILE. If they are on the same FDEV, then it tries the FDEV's rename method, and for either DSK or UNIX FDEVs, if it gets back a Unix ERRNO of 18 (EXDEV; cross-device link) it retries with \GENERIC.RENAMEFILE -- which presumably is what's doing the COPYCHARS/COPYBYTES you're seeing fail.

Dec 10 '24 19:12 nbriggs

I think they should both be BINARY. PDF is for sure, PS may be text, but you can't guarantee that there isn't, say, a binary blob somewhere in there.

I'll change everything to BINARY. But it shouldn't be necessary even to specify this, since BINARY is the default if you don't say TEXT (#1902 )

Dec 11 '24 00:12 rmkaplan

I think they should both be BINARY. PDF is for sure, PS may be text, but you can't guarantee that there isn't, say, a binary blob somewhere in there.

The PS files generated by POSTSCRIPTSTREAM are TEXT. There are no binary objects in PostScript. (At least at the PostScript level when I first wrote POSTSCRIPTSTREAM almost 4 decades ago!) That being said, I can't think of any reason the marking them as BINARY should cause any problems.

According to the PostScript Reference Manual (1985) which I used developing POSTSCRIPTSTREAM:

The standard character set for PostScript programs is the printable subset of the ASCII character set, plus the characters space, tab, and newline (return or line-feed). PostScript does not prohibit the use of characters outside this set; but such use is not recommended since it impairs portability and may make transmission and storage of PostScript programs more difficult.

POSTSCRIPTSTREAM should use that restricted character set. What I developed did. I don’t know about later edits, but I haven’t seen any such code.

Again, I can't think of any reason that marking them as BINARY should cause any problems. So, I have no objection to marking them as BINARY.

Swapping CR and LF helps in correcting a few of the files so far in {NOTECARDS}/library (I'll do a Notecards PR). After swapping. converting unknown fonts of size 13 to size 10 makes a difference.

But there are 2 "known" fonts of size 13, Timesroman 13 MRR and Helvetica 13 MRR. Does anybody remember: are they for real, or should they be reduced to size 10 too?

Regarding the PS language character set --

There are three encodings for the PostScript language: ASCII, binary token, and binary object sequence. The ASCII encoding is preferred for expository purposes (such as this book), for archiving documents, and for transmission via communi- cations facilities, because it is easy to read and does not rely on any special charac- ters that might be reserved for communications use. The two binary encodings are usable in controlled environments to improve the efficiency of representation or execution; they are intended exclusively for machine generation. Detailed in- formation on the binary encodings is provided in Section 3.14, “Binary Encoding Details.”

I believe the two size 13 fonts are real -- they're not the same as size 10 renamed, for sure -- but I can't tell easily because character looks in the current TEdit, applied through the Char Looks menu, aren't working at all for me.
