Peter,


I found this message in archives:

http://www.postgresql.org/message-id/flat/[email protected]#[email protected]

and, as you recommend, tested a speed of building docs on a fresh Ubuntu installation.

50sec for make html
and 14min 50sec for make xslthtml
17 times slower!


Is it still a main stopper for moving to XML?

Hello, Peter.

I've managed to speed up html generation from xml (make xslthtml) from 
32 min. (in my environment) to 4 min. by modifying slowest XSL templates.
All my modifications incorporated in a single file 
stylesheet-xhtml-speedup.xsl, which is included in stylesheet.xsl.
I performed optimization by analyzing output of:
xsltproc --profile --stringparam pg.version '9.6devel' stylesheet.xsl 
postgres.xml

To make sure that result of the transformation is the same, I've 
compared original .html's with .html's generated with modified templates.
Unfortunately xslt generates random id's, so it's needed to exclude them 
before comparing. I do that with:
for f in */*.html; do sed -e 
's/id=\"\(ftn\.\)\?id[a-z][0-9]\+\"/id=\"id\"/g' -i $f ; sed -e 
's/href=\"[^#]*#\(ftn\.\)\?id[a-z][0-9]\+\"/href=\"#\"/g' -i $f; done


So if it's acceptable way to speed up generation of HTML (and maybe some 
other formats), what other steps should we take to move away from SGML?
If the performance is still not satisfying, please let me know, I'll 
continue to optimize xslt.
Beside performance issues, I can see some difference in results of 'make 
html' and 'make xslthtml'. For example, see doc/src/sgml/html/spi.html 
(xslt-generated version doesn't contain the lists of functions).

Best regards,
Alexander

What you've done is awesome. I can't wait to test it on the french
translation.

Nice work!

Hello, Guillaume.

We have plans to use this for russian translation, too. We translate the 
docs by converting (with xml2po) the single xml to postgres-ru.po and 
after translating it we convert it back to xml (we get postres-ru.xml 
here).  (Until now we had to perform one more conversion 
(postgres-ru.xml -> set of sgml's).)
So now we can get russian html/* with:
python xml2po.py -l ru -k -p postgres-ru.po postgres.xml >postgres-ru.xml
xsltproc --stringparam pg.version '9.4.1'  stylesheet.xsl postgres-ru.xml

But I had some doubts about DSSSL and XSL differences. As I noted 
previously there was at least one visible difference. So I decided to 
customize XSL templates to make sure that html's are generated without a 
loss or corruption.
I thought that comparing two HTML sources will not work, as they are too 
different, but maybe we can compare text generated from html by lynx, 
for example.
So I use the following procedure to look for differences:
0. Get dsssl-generated html's
make html
1. Extract text content from html's:
  for f in html/*.html; do fn=`basename $f`; echo $fn; cat $f | perl 
-0pi -pe 's/<B\s*>Note:\s*<\/B\s*>/\<h3>Note<\/h3>/g' | perl -0pi -pe 
's/><BLOCKQUOTE\s*CLASS="NOTE"/><div/ig' >/tmp/$fn; lynx /tmp/$fn --dump 
 >html-text/$fn;
* Some differences are not significant so it's not reasonable to modify 
XSL templates to eliminate them. Difference in "Note" placement and 
spelling is one of them, so I just filter it out.
2. Rename html to html-o and html-text to html-o-text.
3. Generate html's with XSL (use modified templates):
rm -r html; xsltproc --stringparam pg.version '9.4.1' stylesheet.xsl 
postgres.xml
4. Extract text content from html's as above.
5. Make sure that two text html's are identical:
diff -s -u -b -I '^\s*_\+\s*$' html-o-text/xtypes.html html-text/xtypes.html
* Differences in whitespaces and length of "____" lines are not 
significant, too.

For now, I've managed to get the same xtypes.html (I tested my XSL 
customizations with it), but I think, we can eliminate other most 
outstanding (or maybe all) differences likewise.
I can describe XSL customizations in more details, if needed.

Best regards,
Alexander

P.S. I couldn't post the message as a reply due to error on the 
postgresql.org side.

Sorry for not replying earlier but most of the sysadmin team is not
tracking pgsql-docs that closely for issues - afaiks there was a typo in
your mail - the "To" in your mail looked like this:


To: pgsql-docs@postgresql org <[email protected]>
  References: <[email protected]>
<[email protected]>
 <[email protected]>
 <CAECtzeWiOkS=wVnk4T+4Bg3-z-5DGL09jp7ks5QAiDEO4d10+Q@mail.gmail.com>


notice that there is a space after "pgsql-docs@postgresql" instead of
what I suspect should be a "." causing the header syntax check in exim
to barf on the mail.
