`metalog.lua` is a script that reads METALOG file created by pkgbase (make packages) and generates reports about the installed system and issues. This was developed as part of Yang's W2020 University of Waterloo co- operative education term with the FreeBSD Foundation. kevans provided some initial review; we will iterate on it in the tree.

`metalog.lua` is a script that reads METALOG file created by pkgbase

(make packages) and generates reports about the installed system
|
|
and issues

|
|
|
the script accepts an mtree file in a format that's returned by
|
|
`mtree -c | mtree -C`
|
|
|
|
synopsis:
|
|
```
|
|
metalog_reader.lua [-h] [-a | -c | -p [-count] [-size] [-f...]] [-W...] [-v] metalog-path
|
|
```
|
|
|
|
options:
|
|
|
|
* `-a` prints all scan results. this is the default option if no option is
|
|
provided.
|
|
* `-c` lints the file and gives warnings/errors, including duplication and
|
|
conflicting metadata
|
|
* `-Wcheck-notagdir` entries with dir type and no tags will be also included
|
|
the first time they appear (1)
|
|
* `-p` list all package names found in the file as exactly specified by
|
|
`tags=package=...`
|
|
* `-count` display the number of files of the package
|
|
* `-size` display the size of the package
|
|
* `-fsetgid` only include packages with setgid files
|
|
* `-fsetuid` only include packages with setuid files
|
|

|
|
* `-v` verbose mode
|
|
* `-h` help page
|
|
|
|
some examples:
|
|
|
|
* `metalog_reader.lua -a METALOG`
|
|
prints all scan results described below. this is the default option
|
|
* `metalog_reader.lua -c METALOG`
|
|
only prints errors and warnings found in the file
|
|
* `metalog_reader.lua -c -Wcheck-notagdir METALOG`
|
|
prints errors and warnings found in the file, including directories with no
|
|
tags
|
|
* `metalog_reader.lua -p METALOG`
|
|
only prints all the package names found in the file
|
|
* `metalog_reader.lua -p -count -size METALOG`
|
|
prints all the package names, followed by number of files, followed by total
|
|
size
|
|
* `metalog_reader.lua -p -size -fsetid METALOG`
|
|
prints packages that has either setuid/setgid files, followed by the total
|
|
size
|
|
* `metalog_reader.lua -p -fsetuid -fsetgid METALOG`
|
|
prints packages that has both setuid and setgid files (if more than one
|
|
filters are specified, they are composed using logic and)
|
|
* `metalog_reader.lua -p -count -size -fsetuid METALOG`
|
|
prints packages that has setuid files, followed by number of files and total
|
|
size
|
|
|
|
(1) if we have two entries
|
|
```
|
|
./bin type=dir uname=root gname=wheel mode=0755
|
|
./bin type=dir uname=root gname=wheel mode=0755 tags=...
|
|
```
|
|
by default, this is not warned. if the option is enabled, this will be warned
|
|
as the second line sufficiently covers the first line.
