[PATCH 0/8] Regression fixes & improvements in build scripts/preamble

[Akira Yokosawa]

Hi Paul,

This patch series consists of regression fixes of commit ff9ddf1a7a8f
("defer/rcuapi: Tweak Table 9.3 with nimbusmononarrow font") and
improvements in build scripts and the preamble.

Patches #1 and #2 are regression fixes.

Patch #3 adds LaTeX font-package availability check to the experimental
targets. "make" used to print info on necessary font packages but
always ran pdflatex, which could end up in error.  Now "make" aborts
with a message telling where to look.

Patches #4 and #5 take care of warnings from pdfTeX.
Patch #4 resolves mismatch of PDF minor version. The warning is caused
by the change in Ghostscript 9.26 to make PDF 1.7 the default.
Now pdflatex also uses PDF 1.7 for its output.

Patch #5 is to suppress warning from pdfTeX indicating possible
incompatible page group objects within a page. Page group objects are
generated by Inkscape in ".svg -> .pdf" transformation.  As of now,
there is no .svg file with a different page group object. I've not
figured out the way to generate such a page group object by Inkscape.
Note that this change does not affect TeX Live 2013/Debian.

Before these changes,
    grep -i "pdftex warning" -c perfbook.log
returns 128 (can vary depending on page layout).

After these patches are applied, it returns 0 (on TeX Live 2014 or
later).

Patch #6 adds a recipe to detect conflicting page group object. You
need to set an environment variable to enable the recipe.

Patch #7 tweaks target "clean" to keep .fcv and .ltms files.

Patch #8 increases tabsize of fancyvrb snippets for 1c layout.
"tabsize=8" should be easier to read for kernel developers.

You might notice slowdown of "make" due to patch #3. Hopefully, it
wouldn't be irritating for you.

        Thanks, Akira

[PATCH 1/8] defer/rcuapi: Force break between two API in Table 9.3

Subject: [PATCH 1/8] defer/rcuapi: Force break between two API in Table 9.3

The column width specified in commit ff9ddf1a7a8f ("defer/rcuapi:
Tweak Table 9.3 with nimbusmononarrow font") allows both APIs
in this cell to appear without a break between them.
Force the break by specifying a narrower column width for the
cell.

[PATCH 2/8] Makefile: Fix recipe of target 'perfbook-msn.pdf'

[Akira Yokosawa]

From 2a6f16a97317ef5fc9f21edfa7351cef1d950e6d Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/8] Makefile: Fix recipe of target 'perfbook-msn.pdf'

Commit ff9ddf1a7a8f ("defer/rcuapi: Tweak Table 9.3 with
nimbusmononarrow font") botched target 'perfbook-msn.pdf'
and "lmtt" became the default monospace font.
This is because the second "\usepackage{nimbusmononarrow}
in the preamble does nothing.

This can be fixed by removing "\renewcommand*\ttdefault{lmtt}"
instead of adding the redundant "\usepackage{nimbusmononarrow}".

[PATCH 3/8] Makefile: Add check of font package availability

[Akira Yokosawa]

Subject: [PATCH 3/8] Makefile: Add check of font package availability

Add existence check of relatively recent font packages required for
experimental targets.

Those targets used to just print info on required font, and to run
"pdflatex".  Now "make" aborts with a message indicating where to
see if any of required font packages is missing.

[PATCH 4/8] Specify PDF minor version 1.7

[Akira Yokosawa]

From f6814ac4124a9a383ca8ca7f683d46f1365ace58 Mon Sep 17 00:00:00 2001
From: Akira Yokosawa <akiyks@gmail.com>
Date: Sat, 23 Feb 2019 18:25:33 +0900
Subject: [PATCH 4/8] Specify PDF minor version 1.7

Ghostscript 9.26 changed the default PDF output to 1.7 [1].
This causes a lot of warning messages in perfbook.log, saying:

    pdfTeX warning: pdflatex (file ./cartoons/1kHz.pdf): PDF inclusion:
    found PDF version <1.7>, but at most version <1.5> allowed
    <cartoons/1kHz.pdf, id=11175, 319.79472pt x 287.27324pt>
    File: cartoons/1kHz.pdf Graphic file (type pdf)

This warning can be suppressed by setting "\pdfminorversion=7"
in the preamble.

[PATCH 5/8] Suppress warning from pdfTeX on figures transformed by Inkscape

Subject: [PATCH 5/8] Suppress warning from pdfTeX on figures transformed by Inkscape

This change suppresses warnings such as:

    <./cartoons/r-2014-branch-error.pdf

    pdfTeX warning: pdflatex (file ./cartoons/r-2014-branch-error.pdf):
    PDF inclusion: multiple pdfs with page group included in a single page>

This is a known issue of pdfTeX [1].
The message is emitted when multiple PDF files generated by
Inkscape appear in a single page. This issue has not caused
any problem in perfbook so far.

The variable \pdfsuppresswarningpagegroup is available since
pdfTeX 1.40.15 (TeX Live 2014). So this change doesn't affect
TeX Live 2013/Debian on Ubuntu Trusty.

[PATCH 6/8] Makefile: Add optional recipe to detect conflict in page group object

[Akira Yokosawa]

From 91e7ad2b3e5dfae239d3f4e64d92b7c21ba9ed75 Mon Sep 17 00:00:00 2001
From: Akira Yokosawa <akiyks@gmail.com>
Date: Sat, 23 Feb 2019 19:26:57 +0900
Subject: [PATCH 6/8] Makefile: Add optional recipe to detect conflict in page group object

As long as "page group objects" are identical, setting
\pdfsuppresswarningpagegroup variable done in the previous commit
is safe.

This commit adds an optional recipe in ".svn -> .pdf"
transformation to extract page group object from the generated .pdf
file, and to compare it with the expected one given in "pagegroup".

The added recipe is enabled only when an environment variable
"PERFBOOK_CHKPAGEGROUP" is set "on". The check requires a command
named "qpdf", which is available on most Linux distributions.

Subject: [PATCH 7/8] Makefile: Don't remove .fcv and .ltms files in target 'clean'

In the case of a build error due to out-of-date CodeSamples/snippets.d,
Removing the outdated file suffices. .fcv and .ltms files need not
be removed.  Defer their removal to the target 'distclean'.

While we are here, add CodeSamples/snippets.mk to OBSOLETE_FILES.

Most readers are supposed to be used to tabsize=8.
Use it for 1c layout.
