Hi there,
I tried to use git ptx-patches fromwithin a package and noticed it doesn't work.
I could track down the problem to this command (from scripts/git-ptx-patches):
> man git-format-patch | grep -q -e --notes
Executing this command manually results in this error message:
> Error executing formatting or display command.
> System command (cd "/usr/share/man" && (echo ".pl 11i"; /bin/bzip2 -c -d '/usr/share/man/man1/git-format-patch.1.bz2') | /usr/bin/gtbl | /usr/bin/nroff -mandoc | less) exited with status 141.
> No manual entry for git-format-patch
Interestingly executing

works as expected. I have no idea what's wrong here.

Maybe this is caused by some aliases or interactive/non-ineractive magic.
Does it help to replace "man git-format-patch" with "git format-patch
--help" or "man -P cat git-format-patch"?

Unfortunately no :(
git format-patch --help | grep -q -e --notes
Error executing formatting or display command.
System command (cd "/usr/share/man" && (echo ".pl 11i"; /bin/bzip2 -c -d '/usr/share/man/man1/git-format-patch.1.bz2') | /usr/bin/gtbl | /usr/bin/nroff -mandoc | /usr/bin/less) exited with status 141.
No manual entry for git-format-patch
$ man -P cat git-format-patch | grep -q -e --notes
Error executing formatting or display command.

Do you have git-format-patch's manpage, i.e. does
man git-format-patch
work? On bash, what happens on:
$ man -P cat git-format-patch | grep -q -e --notes
$ echo ${PIPESTATUS[@]}
Does
strace -f -o /tmp/lala man -P cat git-format-patch | grep -q -e --notes
give any insights (e.g. where does the 141 come from?)
Best regards
Uwe

Yep, that man page is installed.

$ man -P cat git-format-patch | grep -q -e --notes
Error executing formatting or display command.
System command (cd "/usr/share/man" && (echo ".pl 11i"; /bin/bzip2 -c -d '/usr/share/man/man1/git-format-patch.1.bz2') | /usr/bin/gtbl | /usr/bin/nroff -mandoc | cat) exited with status 141.
No manual entry for git-format-patch
$ echo ${PIPESTATUS[@]}
1 0

Somewhat. The 'culprit' is grep so far:
$ man -P cat git-format-patch | grep -q -e --notes
Error executing formatting or display command.
System command (cd "/usr/share/man" && (echo ".pl 11i"; /bin/bzip2 -c -d '/usr/share/man/man1/git-format-patch.1.bz2') | /usr/bin/gtbl | /usr/bin/nroff -mandoc | cat) exited with status 141.
No manual entry for git-format-patch
$ man -P cat git-format-patch | grep -e --notes
[--[no-]cover-letter] [--quiet] [--notes[=<ref>]]
--notes[=<ref>]
It seems grep slightly behaves differently when used with -q. It closes STDIN as soon as it detects the pattern.
But the closed pipe results in an EPIPE returned from write(2) within cat which exits with an error.
A working variant/workaround ist:
$ man -P cat git-format-patch | grep -e --notes > /dev/null
$ echo $?
0

Alexander

My man (from the Debian package man-db 2.6.2-1) doesn't show this
behaviour. Is your version older or newer?

I don't think this is related to man (what's man-db BTW?) at all.
I think the versions of cat and grep behave differently. I have installed grep-2.16 and coreutils-8.21 (current Gentoo stable versions).

This is caused by 'man':
$ (cd "/usr/share/man" && (echo ".pl 11i"; /bin/gunzip -c -d '/usr/share/man/man1/git-format-patch.1.gz') | /usr/bin/gtbl | /usr/bin/nroff -mandoc | cat) | grep -q -e --notes
$ echo ${PIPESTATUS[@]}
141 0
$ man git-format-patch | grep -q -e --notes
$ echo ${PIPESTATUS[@]}
0 0
Either man is executing something else here or it ignores the return value.
Maybe it doesn't start a pager if stdout is a pipe, because:
$ (cd "/usr/share/man" && (echo ".pl 11i"; /bin/gunzip -c -d '/usr/share/man/man1/git-format-patch.1.gz') | /usr/bin/gtbl | /usr/bin/nroff -mandoc) | grep -q -e --notes
$ echo ${PIPESTATUS[@]}
0 0

man-db is the package that provides /usr/bin/man on Debian. Also man-db
from Debian unstable (i.e. 2.6.6) is unaffected.
> I think the versions of cat and grep behave differently. I have
At least my grep also closes its input with -q and makes cat unhappy:
$ { seq 1 2000 | cat; echo >&2 $?; } | grep -q 1
141
$ { seq 1 2000 | cat; echo >&2 $?; } | grep 1 > /dev/null
0
So I still think it's a man problem. Reading the output of
strace -o /tmp/tralala man git-format-patch | grep -q -e --notes
"my" man doesn't use system to render the manpage. At least it doesn't
do any execvp and it opens /usr/share/man/man1/git-format-patch.1.gz
itself.
So again, what is your man version?

For completeness although I think its proven to be unrelated:
grep 2.12-2 + coreutils 8.13-3.5 (i.e. Debian stable)

Both commands work well here:
$ { seq 1 2000 | cat; echo >&2 $?; } | grep -q 1
0
$ { seq 1 2000 | cat; echo >&2 $?; } | grep 1 > /dev/null

You might be missing the -f option? My strace shows several execve. One of them is

Mh, those numbers made me wonder. I checked the sources of this version and
found this snippet:

It seems that the default (? dunno why this variant was installed though) of
man behaves differently. I now installed man-db-2.6.6 and it works now \o/
Thanks for the hint
