RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

This is about the internal platform-python-pip, not the user facing python3-pip, therefore I don't think we should document this.

Description Lukáš Zachar 2019-09-27 06:16:22 UTC
Description of problem:

To make ubi8 image as small as possible and thus good choice for building own images on top we should get rid of unnecessary dependencies. 

One of such deps is probably pip (and friends) installed by platform-python.


Version-Release number of selected component (if applicable):
platform-python-3.6.8-15.el8


Additional info:
Discussion started in bug 1701286#c7

Comment 1 Tomas Orsava 2019-10-03 09:53:37 UTC
First we need to decide what dependencies from platform-python to drop (if any):
- 1.9M    platform-python-pip-9.0.3-15.el8.noarch.rpm
- 632K    platform-python-setuptools-39.2.0-5.el8.noarch.rpm

pip seems like an obvious candidate, as there are not that many packages that could possibly rely on it, and it's much larger. With setuptools I'd be hesitant.


And if we decide to drop dependencies, we should do it as soon as `rhel-8.2.0` branches are created and send a heads-up to rhel-devel mailing list, to give everyone plenty of time to react.

Comment 2 Miro Hrončok 2019-10-03 11:12:19 UTC
If we are worried about RPM packages which BuildRequire pip or setuptools but are not declaring that, this has a solution:

I would say we're worried both that:
- the BuildRequires won't be there which will change the build, but the devel won't notice it (however, thanks to RPM diff, I think this is not as pressing)
- the Requires isn't there and the package will crash / miss-behave when used by the customer - this is the bigger issue, I think.

To clarify, https://src.fedoraproject.org/rpms/python3/pull-request/128 only solves the BuildRequires case.

Comment 5 Charalampos Stratakis 2019-10-08 13:38:17 UTC
From the python3 SPEC file:

RHEL8 was forked from F28 and thus required python3-setuptools/pip here
for the rewheel module to work. We've since backported the use of RPM
prepared wheels from F29+ into RHEL8, and thus this dependency isn't
strictly needed.

However, it is possible, that some packages in BaseOS actually depend on
setuptools/pip without declaring the dependency in their spec file. Thus
we're keeping these dependencies here to avoid the possibility of breaking
them.

Comment 11 James Cassell 2020-02-03 22:58:57 UTC
It's a good change, but I think it'd be better to drop even the Recommends unless there is system functionality that is enhanced/enabled by having this package present.  Seems like the packages actually depending upon this one should just Require it themselves.  Installed, it is 7.4 M on disk.
