When changing busybox configuration, it's helpful to list the size change.

So for anyone else curious, buildhistory reports the package size (not
the binary size) as:

-PKGSIZE = 573632
+PKGSIZE = 585144

For future, this seems like the sort of thing we need a class for.
There is a texinfo.bbclass now...

Patch 1/3 the busybox change.  I'm not sure we really want to make that change 
as it will increase the size of busybox.

(following is me thinking aloud and hopefully someone will have a suggest on how 
best to unify this..)

I'm wondering if instead of forcing the change for everyone via the busybox 
change, if it makes sense to add a image validation routine or something that 
verifies if the DOC_COMPRESS is set, that the corresponding tool was installed 
into the target environment (along w/ man, info or other appropriate items.. and 
the pkgs-docs was set as well.. if any of those are missing then a warning 
should probably be presented.)

I'm sure there is probably a better way to set this via a distribution 
configuration switch or something as well.. maybe something like?

DISTRO += "man info"

That could then force the man and info systems to add a dependency on bz2 (or xz 
or whatever else was set in DOC_COMPRESS)..  and also add man, info and the 
associated man and info pages to the image itself.

(As I see it, DOC_COMPRESS is really a distribution wide setting, so we should 
treat it as such...)

I think there are a few issues here. Firstly, this postinst can run at
build time which means there is a dependency on texinfo-native. I guess
if this fails, it will just run on target so its probably "harmless" but
not deterministic. Secondly, anything installing an info directory
really needs to update the dir files with its own postinst. For optimal
handling at rootfs time, that will need trigger/intercept support.

So this probably can merge as it improves things however we need some
enhacement bugs opening related to this, we may want to force the
postinst to run on target for now so things are deterministic too.

Cheers,

Richard

There's a texinfo.bbclass which all recipes installing info files are
probably inheriting anyway, so moving the postinst there should solve
the race on the directory.  That class says that texinfo-native is
assume-provided but you'll want to check that usual configurations
ship install-info alongside makeinfo on the distributions we support.

Hi Richard,

Yes, you are right, I will refer Ubuntu to add a script to 
postinst_intercept
to do that, run it after all packages have been installed at build time.

And about trigger, but I have no idea about how to implement it. It seems
we support pkg_postinst/pkg_preinst but don't support pkg_triggers,
Refer triggers in install-info_5.2.0.dfsg.1-4_amd64.deb, we got:
...
interest-noawait /usr/share/info
...

Hi Ross,

I am afraid moving the postinst to texinfo.bbclass will cause some
potential issues:

- It will be invoked many times if multiple packages installed.

- We could not use a generic way to name pkg_postinst.
   Such as texinfo recipe, we need pkg_postinst_info.

I will refer what Ubuntu/Debian did, add postinst/postrm to info
packages.

Since we care about the size, and affect of the fix is global.

How about conditionally add 'xz/bz2/gzip' to info/man's
RDEPENDS according DOC_COMPRESS value.

Sure, we could make it a trigger in the future.

Many classes extend the postinst scripts, so this isn't a problem.
