[solved] bigpkg doesn't like /var/lib/pacman/local/ALPM_DB_VERSION

karol · 2015-01-15 13:16:41

I can't use bigpkg anymore, because it expects everything in /var/lib/pacman/local/ to be a directory:
https://aur.archlinux.org/packages/bigpkg/ -> http://allanmcrae.com/scripts/bigpkg
Here are the important lines:

LOCAL_DB_PATH="/var/lib/pacman/local"

file = LOCAL_DB_PATH + "/" + dir + "/desc"
f = open(file, "r")

After running 'pacman-db-upgrade', /var/lib/pacman/local/ALPM_DB_VERSION was placed there

$ pacman -Qo /var/lib/pacman/local/ALPM_DB_VERSION
error: No package owns /var/lib/pacman/local/ALPM_DB_VERSION
$ cat /var/lib/pacman/local/ALPM_DB_VERSION
9
$ bigpkg
Traceback (most recent call last):
  File "/usr/bin/bigpkg", line 83, in <module>
    parse_package_info(pkg, dir)
  File "/usr/bin/bigpkg", line 51, in parse_package_info
    f = open(file, "r")
NotADirectoryError: [Errno 20] Not a directory: '/var/lib/pacman/local/ALPM_DB_VERSION/desc'

I can remove that file and make bigpkg work again, but it breaks pacman:

error: failed to initialize alpm library
(database is incorrect version: /var/lib/pacman/)
error:   try running pacman-db-upgrade

Is it a bug? If not, can someone please fix bigpkg? I don't speak python, so I can't do it myself :-(

Have you tried rebuilding bigpkg against pacman 4.2?

karol · 2015-01-15 14:26:11

Yup.
AFAICT the bigpkg script expects no files, just directories in /var/lib/pacman/local/. If I can ask bigpkg to ignore /var/lib/pacman/local/ALPM_DB_VERSION I'm all set.

Download just the script from Allan's blog, the package is outdated. I'm not sure this will solve the problem, but it'sworth a shot.

Have a look at the PKGBUILD: https://aur.archlinux.org/packages/bi/bigpkg/PKGBUILD
It only downloads and installs the script.

Just use expac...

I do, I do :-)

$ type greatpkg
greatpkg is aliased to `expac -s -H M "%-30n %m" | sort -rhk 2 | head'

I believe you can use bigpkg if you patch it like this:

for dir in os.listdir(LOCAL_DB_PATH):
    try:
        pkg = dir[0:dir.rindex("-",0,dir.rindex("-"))]
        pkg_list.append(pkg)
        parse_package_info(pkg, dir)
    except ValueError:
        pass

So Allan broke his own script when updating ALPM?

Allan · 2015-01-15 23:32:38

Allan has not looked at that script in a few years,,,

Can you post a diff? I have no idea where to put it.
bigpkg complains

$ /usr/bin/bigpkg_patched
Traceback (most recent call last):
  File "/usr/bin/bigpkg_patched", line 53, in <module>
    pkg_list.append(pkg)
NameError: name 'pkg_list' is not defined

if I try to use the part you posted before the line that says

pkg_list = []

but I still have problems with

file = LOCAL_DB_PATH + "/" + dir + "/desc"
f = open(file, "r")

There is a similar for-loop in the original code that you have to replace

diff --git a/bigpkg b/bigpkg
index b0ac16f..f8619ef 100644
--- a/bigpkg
+++ b/bigpkg
@@ -78,9 +78,12 @@ pkg_provides = {}

-    parse_package_info(pkg, dir)

Thank you very much :-)

I expected as much, but the nominal comedic value is golden.

Patching bigpkg as proposed above gives a Syntax error in this location:
# bigpkg

  File "/usr/bin/bigpkg", line 84
    except ValueError:
         ^
SyntaxError: invalid syntax

Dunno Python so I could just check if I closed parenthesis above line 84 and yes they are =}
