afl case f1/id:000103,sig:06,src:009024+009105,op:splice,rep:2 (jes@)

Fixing this will probably require reworking the whole bufcat() concept.

While roff_parseln() prevents .ce and similar requests in the middle

loc ** exist * algo * size ** imp **

of a tbl, the guard is no longer effective when the .ce is wrapped

in a roff block, for example a conditional. The resulting assertion

has never been seen in any real-world manual page.

This is too dangerous to fix before release because it requires

reorganizing the very delicate internals of roff_parseln(),

which risks causing more severe bugs.

- \\ in high-level macro arguments

- .als only works for macros in mandoc, not for user-defined strings.

Currently, \\ is expanded in two situations:

Also, the "val" field in struct roffkv would have to be replaced

1) macro and string definition (roff.c setstrn())

with a pointer to a reference-counted wrapper, and an alias

2) macro argument parsing (mandoc.c mandoc_getarg())

would have to point to the same wrapper as the original.

For user defined macros, the second happens in time because of ROFF_REPARSE.

.als to undefined does nothing; the alias is not created.

But for standard high-level macros, it only happens after entering the

.rm'ing the original leaves the alias to point to the old value.

- mandoc replaces all ASCII control characters except tab and line feed

with '?' during input. It would be better to replace them with

Unicode escapes in preconv_encode() or somewhere in the vicinity,

such that the already existing better replacement strings show

up in the output. Emulating groff is not desirable: groff replaces

0x00, 0x0b, and 0x0d to 0x1f with the empty string (bad because

that's easy to overlook for the document author), 0x01 with '.'

(very confusing), and passes through 0x02 to 0x08, 0x0c, and 0x7f

raw (bad because that is insecure output). Remember that 0x07 may

need special handling because it is sometimes used for certain

delimiters, so it may need handling *after* roff.c rather than before.

reminded by John Gardner 16 Jun 2020 14:26:28 +1000

Actually, more ASCII control characters than just 0x07 may need

later handling because they can for example be used in macro names.

So they may need handling after roff(7) processing.

A better solution, but much harder to implement, would be to

input HYPHEN-MINUS becomes output \(mi, unless it is part of a

Also, check whether there are more such cases (e.g., +?).

Several areas can be cleaned up to make mandoc even faster. These are

- improve hashing mechanism for macros (quite important: performance)

- improve hashing mechanism for characters (not as important)

- the PDF file is HUGE: this can be reduced by using relative offsets

- instead of re-initialising the roff predefined-strings set before each

parse, create a read-only version the first time and copy it

loc * exist ** algo ** size * imp **

* structural issues

- We use the input line number at several places to distinguish

- POSIX says in the documentation of sysconf(3) that PATH_MAX

same-line from different-line input. That plainly doesn't work

is allowed to be so large that it is a bad idea to use it

with user-defined macros, leading to random breakage.

for sizing static buffers. So use dynamic buffers throughout.

See the file test-PATH_MAX.c for details.

- Is it possible to further simplify ENDBODY_SPACE?

- Find better ways to prevent endless loops

in roff(7) macro and string expansion.

- Finish cleanup of date handling.

- make buffers for parsing functions const

Decide which formats should be recognized where.

Update both mdoc(7) and man(7) documentation.

- Inspect httpd(8) logs on man.openbsd.org and consider

whether logging can be improved, where bad syntax comes from,

and what needs to be done to get rid of COMPAT_OLDURI.

- Enable HTTP compression by detecting gzip encoding and filtering

output through libz.

- Sandbox (see OpenSSH).

- Privilege separation (see OpenSSH).

- Enable caching support via HTTP 304 and If-Modified-Since.

- Allow for cgi.h to be overridden by CGI environment variables.

Otherwise, binary distributions will inherit the compile-time

behaviour, which is not optimal.

- Have Mac OSX systems automatically disable -static compilation of the

CGI: -static isn't supported.

- Can the distinction between .Vt and .Va be made stricter,

recommending .Vt extern char * Ns Va optarg ; ?

What about the block macro properties of .Vt in the SYNOPSIS?

- .Cd # arch1, arch2 in section 4 pages:

find better way to indicate multiple architectures, maybe:

allow .Dt vgafb 4 "macppc sparc64"

already shown as "Device Drivers Manual (macppc sparc64)"

for apropos, make that "vgafb(4) - macppc # sparc64" instead of "- all"

groff can be made to show multiple arches, too, but it is

tedious to do the string parsing in roff code...

Do we need to fix existing manuals?

Do we need to fix the definition of the mdoc(7) language?
