Listing only manually installed package

Listing only manually installed package

[Yasuhiro KIMURA]

Hello.

When installing one package, it is quite common for several other
packages to be automatically installed as dependencies. And output of
`cygcheck -c` includes both of them. Then is there any way to list
only manually installed package?

Best Regards.

AFAIK, there's no way to tell if a package was manually selected or not.
Cygwin's setup just don't store this information.

I checked /etc/setup/installed.db on my 32bit and 64bit console but in
each case all lines end with "0". Therefore,

As you say, unfortunately there seems to be no way to tell if a
package was installed manually or automatically.

I have 1522 packages installed: 421 manually installed packages and 1101
automatically installed.

It appears you have 0 manually installed packages in the Cygwin installation you
are looking at, if you used a Cygwin setup-compatible installer, ran exactly the
commands quoted above, and they gave you consistent answers.

It is possible setup has been changed incompatibly and no longer maintains that
field correctly, but in case not, *NEVER* run setup and tell it to remove
obsolete packages: it will remove all non-Base packages that do not have others
which depend on them!

Just checked the setup sources, so unless there is a bug, you are running a
setup version over 5 years old, or not running Cygwin setup, user_picked is part
of the package metadata that is still read from and written to installed.db.

FYI,  I'm seeing the same thing as Yasuhiro.

I purchased a new personal Windows 10 Home laptop and Windows 10 Pro 
desktop in March, and received a new Windows 10 Enterprise laptop for 
work this week.  On all 3 systems I downloaded setup-x86_64 from 
cygwin.com and first installed cygwin without adding any additional 
packages.  I then ran setup again to install a more packages that I 
needed for personal use or work use (respectively).  On all three 
machines the "manual" commands show nothing and the "auto" commands 
(appear to) show everything.  Its been a couple months so I don't 
remember what I manually installed on the personal machines, but the 
work machine was only 2 days ago, and I remember installing at least bc 
and psmisc (and maybe curl).  FWIW, I'm not sure if its relevant, but 
running setup now and selecting "Picked" from the drop down shows 
"Nothing to install or update".

Is there a log file somewhere where I can see what packages were 
installed/updated in each run of setup?

PS: I would love a way to get this listing, as it would have simplified 
installing cygwin on all 3 systems (replicating the installations on the 
systems they replaced).

$ less /var/log/setup.log{,.full}
$ fgrep -c 'Extracting from file://' /var/log/setup.log{,.full}

setup.log.full gives the details of the last run on that installation
setup.log is the summary of all runs on that installation

There are two sources for a complete package list:

installed packages:
$ awk '3 == NF {print $1}' /etc/setup/installed.db
$ sed '1d;/\s[01]$/s/\s.*$//' /etc/setup/installed.db

package directories:
$ find <local package directory>/*tp*%3a%2f%2f*%2f/*/release/*/ -type d | \
sed 's!/$!!;s!^.*/!!' | sort -u
but this may include some non-packages, as would similar approaches.

I tested this issue with clean installed 64bit Windows 10 1909.

At first I downloaded setup-x86_64.exe from Cygwin Web page and
executed it. According to start message, version is 2.904.

Then I installed only Base packages, exited setup-x86_64.exe, opened
Cygwin console and checked /etc/setup/installed.db. All lines end with
"0".

Next I executed setup-x86_64.exe again, selected 'openssh", installed
it, and checked /etc/setup/installed.db. All lines still end with "0".

After that I installed some other packages. But there is no line
ending with "1" in /etc/setup/installed.db.

Therefore if this isn't expected behavior, there must be bug in latest
(or recent) version of setup.exe.

FYI, I removed all cygwin-related files from my main PC and re-setuped
cygwin environment about a month ago.

Unfortunately, it seems there is a bug (since 2.895, 18 months ago, 
...), and this information doesn't always get recorded correctly.

Thanks for drawing my attention to this.

Thanks for spotting the bug - I missed the user_picked parameter being defaulted.

Is there any way to run setup with suitable parameters and have it set the
user_picked field in installed.db?

Or is it down to finding packages in installed.db that are roots, with no
installed packages dependent on them, according to the setup.ini
depends2/requires lists, and producing an updated installed.db?

Just a data point:
Csaba@AMDAHL ~
$ grep -c '\s1$' /etc/setup/installed.db

Csaba@AMDAHL ~
$ grep -c '\s0$' /etc/setup/installed.db

I can't remember what the pristine state of the Base category packages are,
I've messed around with the setup files so much for so long.
