 Posted: Mon May 19, 2003 3:08 pm Post subject: Script reports new/removed packages after 'emerge sync' |
 |
|
EDIT: Use /usr/sbin/esync, provided by app-portage/esearch.
Known bug(s):
This script looks at the portage tree, runs a sync, looks at the portage tree again, and reports if any packages are new or removed. Since the script runs an emerge sync, it must be run as root.
I'm no programmer, so I make no claims about quality of code. Warranty: "It works for me".
I decided to make this one in python after some problems with a similar bash script. Using python seems to have improved speed over using the bash/find method.
| Code: | #!/usr/bin/env python2.2
import sys,portage,os
from output import *
if (not sys.stdout.isatty()) or (portage.settings["NOCOLOR"] in ["yes","true"]):
nocolor()
def portTree():
return portage.portdb.cp_all()
print green("*")+" Recording tree information before syncing."
before = portTree()
os.system("/usr/bin/emerge sync")
print green("*")+" Recording tree information after syncing.\n"
after = portTree()
rmd = before
new = after
matches = []
# Find common elements in before & after.
for pos in range(len(before)):
if after.count(before[pos]):
matched = after.index(before[pos])
matches.append(after[matched])
# Remove common elements (matches) from before & after, creating "new" and "removed" packages.
for pos in range(len(matches)):
new.remove(matches[pos])
rmd.remove(matches[pos])
# Report results
print "- - - ---------------------------------------------------------------------"
print "New packages [%s]" % (len(new))
print "- - - ---------------------------------------------------------------------"
if (len(new)):
for what in new:
full_pkg = portage.best(portage.portdb.xmatch("match-all", (what.split("/")[1]) ))
print green("*")+" "+what
print "\t"+portage.portdb.aux_get(full_pkg, ["DESCRIPTION"])[0]
else:
print yellow("*")+" No new packages."
print
print "- - - ---------------------------------------------------------------------"
print "Removed packages [%s]" % (len(rmd))
print "- - - ---------------------------------------------------------------------"
if (len(rmd)):
for what in rmd:
print yellow("*")+" "+what
else:
print green("*")+" No packages removed."
print
print green("*")+" Done." |
EDIT:
2003.05.20: Added import lines I somehow managed to omit.
2003.05.29: Added reference to aux_get(): ebuild for '' does not exist at: bug post.

Great to hear you made this script, as I've been looking for something like this now, and was just about to make one myself. I get an error, however, when I attempt to run it
| Code: | warlord portage # ./portage
./portage: line 3: syntax error near unexpected token `('
./portage: line 3: `if (not sys.stdout.isatty()) or (portage.settings["NOCOLOR"] in ["yes","true"]):' |
Any ideas? Is this script suppose to have a specific filename?

Woops... I left out a very important part... no idea how. | Incorrect snippet wrote: | | Code: | #!/usr/bin/env python2.2
if (not sys.stdout.isatty()) or (portage.settings["NOCOLOR"] in ["yes","true"]):
nocolor() |
|
| Corrected snippet wrote: | | Code: | #!/usr/bin/env python2.2
import sys,portage,os
from output import *
if (not sys.stdout.isatty()) or (portage.settings["NOCOLOR"] in ["yes","true"]):
nocolor() |

Original post/script has been updated.

Anything should work. The old bash version suggested /usr/bin/emerge2. For testing, I was using em2. I have it as /usr/bin/es (emerge sync) now.

| Code: | | print "\t"+portage.portdb.aux_get(full_pkg, ["DESCRIPTION"])[0] |
That code breaks if there is no .ebuild file. When it fails, it will look something like this: | Code: | !!! aux_get(): ebuild for '' does not exist at:
!!!
Traceback (most recent call last):
File "/usr/bin/es", line 49, in ?
print "\t"+portage.portdb.aux_get(full_pkg, ["DESCRIPTION"])[0]
File "/usr/lib/python2.2/site-packages/portage.py", line 3333, in au
raise KeyError
KeyError |
I haven't looked into fixing it yet, but its on my list. In the meantime, if anyone is interested, feel free to submit corrections.

Will produce the following error (or similar) if an ebuild file is missing. | Code: | !!! aux_get(): ebuild for '' does not exist at:
!!!
Traceback (most recent call last):
File "/usr/bin/es", line 49, in ?
print "\t"+portage.portdb.aux_get(full_pkg, ["DESCRIPTION"])[0]
File "/usr/lib/python2.2/site-packages/portage.py", line 3333, in au
raise KeyError
KeyError |
I haven't worked on resolving it yet, though its on my list of things to do. Feel free to contribute corrections in the meantime.
