 Posted: Sun Aug 09, 2009 3:45 pm Post subject: Get ewarn/einfo during --pretend? |
 |
|
I looked everywhere, but maybe I'm missing it...
Is it possible to see the pkg_postinst/pkg_preinst ewarn/einfo messages from a --pretend command?
Meaning, I'd like to see the same messages that would be output after an emerge install, when I do:
emerge -pvuDN world
or
emerge -pvuDN pkgname
Thanks |

I'm pretty sure no... elog would only come into play *after* packages are *installed*.
I want to see these messages when I do a --pretend install (I thought that was pretty clear?)... |

Ok so you mean somehow to get output like this? | Code: | # emerge -pv lvm2
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] sys-fs/lvm2-2.02.49-r2 USE="lvm1 readline static -clvm (-cman) (-selinux)" 0 kB
einfo "Building static LVM, for usage inside genkernel"
ewarn "Building shared LVM, it will not work inside genkernel!"
einfo "Doing symlinks"
einfo "Doing device-mapper"
einfo "Doing lib"
einfo "Doing main build"
einfo "Testcases disabled because of device-node mucking"
einfo "If you want them, compile the package and see ${S}/tests"
Total: 1 package (1 reinstall), Size of downloads: 0 kB

If this would include all of the potential messages warning about something that needs to be done, major changes, etc, then yes...
Again, basically any/all messages that would output at the end of the install if the package was actually installed. |

Mike I think he wants a pre-viewer before emerging. You could do something like this | Code: | for i in $(eix -Iuc|awk '/U/ {print $2} ;do echo "$i";grep "einfo" $(equery w $i) ;done
app-text/docbook-xml-dtd
dev-python/wxpython
kde-base/kdelibs
einfo "Building API documentation"
einfo "Installing API documentation. This could take a bit of time."
sys-apps/baselayout
einfo "Creating directories..."
virtual/libusb
x11-libs/gtksourceview
x11-libs/wxGTK |
To use this you need "eix" and "gentoolkit" installed.
Edit Used " eix -Ic " to generate list.

| Quote: | -u, --upgrade, --upgrade+, --upgrade-
Only match packages which have at least one slotted version
installed which is not the best version within that slot. This
means usually that you should either upgrade or downgrade that
package.
However, the test takes also UPGRADE_TO_HIGHEST_SLOT (see below)
into account.
If you use --upgrade+ or --upgrade-, then the test acts as if
LOCAL_PORTAGE_CONFIG is true or false. Otherwise, this decision
is based upon UPGRADE_LOCAL_MODE.
If you want to see only packages with downgrade recommendations,
you might make use of the FORMATSTRING features described below. |
RTFM
I used -u because I thought it would show only what had updates but thats not matching

So this I think would do it with emerge (for portage < 2.2) otherwise emerge -upDN world | Code: | | for i in $(emerge -upDN @system @world |awk '/\[/ {print $4}') ;do echo "$i";egrep 'elog|einfo|ewarn|qa|error' $(equery w $i) ;done |

Converted to a script. If you pass system or world to it, it will locates einfo, elog, ewarn, qa and error info from either "emerge system" or "emerge world". If you are afraid that this script might set your box on fire, just make sure you have a bucket of saltwater nearby to pour on it, so as to short the fire out 
Usage einfo.sh system for the system listings. If you run einfo.sh by itself or einfo.sh world you the listings for everthing.

Holy crap... !
Thanks for taking this and running with it, but as ianap, most of this is greek to me...
So, is it possible a new emerge switch could come out of this? Maybe --messages (-m) or something? I'd really prefer something that was officially maintained as part of the official tool (emerge) for installing programs.
If not, at least maybe an officially supported alternate tool - call it premerge?
Anyway, thanks again for the efforts... |

You're welcome.
And yes it definitely needs work, especially error checking. For example this command without the pretend switch can probably damage the tree - not sure -
EDIT: yes I am sure - EDIT again no not sure - there was a bug in portage that coincided with testing, -so not sure. Still better to be safe, and besides this only makes sense in pretend mode anyway. | Code: | | einfo.sh $(emerge -uDNp @system @world | awk -F'] ' '{print $2}') |
So something like | Code: | alias emerge='emerge -p'

libertytrek you would have to post to bugs gentoo requesting a method or tool to preview the einfo. Actually this previewer is not a bad idea at all for an "emerge -uDN" . If you update monthly or more often then you would not be buried in the output. If you redirect the --emptytree output to a file it is manageable.
EDIT 8-13-2009 the below paragraph as its the only instructions at this time. Also updated the script which needs only the help section finished.
This isnt quite finished, the help section needs finishing and minor cleanup., but you can pass it short emerge flags, -D, -e, -h or help, -N, -u, nc <nocolor>, system, sys, @system, @sys, wld, world, @world, @wld". The short guys I leave to you to figure out. Typical useage would be " einfo.sh wld -uDN " or " einfo.sh @sys -uDN ". Also as the last switch or flag "pkg or P or PKG" you can list packages that you want to check. Use the pkg flag and you don't have to pass world or system just "einfo.sh -uDN pkg baselayout glibc" and if theres any einfo for those packages it will listed. It also will have help section That explains the options.
