PN is uppercase

PN is uppercase

[Ralf Spiwoks]

Hi,

I am getting warning issues about the package name containing uppercase letters, e.g.

WARNING: QA Issue: PN: ... is upper case, this can result in unexpected behavior. [uppercase-pn]

And sometimes later, I am getting many errors like the following one:

ERROR: ...-1.0-r0 do_package_qa: QA Issue: /usr/bin/... contained in package ... requires libgcc_s.so.1, but no providers found in RDEPENDS_...? 
[file-rdeps]


TWO questions:

1) Are those two issues related?

2) What is the logic behind allowing only lower case package names? This is to me
    a serious restriction on the use of Yocto.

Thanks for your help,

Ralf Spiwoks, CERN

Probably not, unless you're trying to use a mixed-case override.

Two reasons: some package managers forbid packages with uppercase
names; and for performance reasons overrides are lowercase and as
package names are often embedded in overrides this implies that
package names need to be lowercase.

What's the problem with using lowercase names?

Hi Ross,

Thanks for your email. I am realising that I have not replied to your
email earlier. Sorry. I guess it was partly because your answer put
me slightly off. On the one hand, I thought that as a general approach,
Linux was case sensitive, unlike its big rival Windows, and I was not
aware  of package managers which would explicitly forbid uppercase
package names. I find the approach of allowing only lowercase package
names quite limiting, and frankly a drawback for using Yocto

On the other hand I have a few tens of packages to maintain, which
have uppercase letters in the package names and which did work with
Yocto in previous versions. So, because of a new convention we would
have to rework some of the packages or ignore the warning messages.
And until we find the effort for reworking those package recipes we
will stay with the latter option.

Thanks for your patience and your explanations. Cheers,

Ralf.

The package name rules are not new, they have been with OE/YP forever
so it should have failed always. Similar to debian see

We had to pick a convention. Debian is well documented, conservative and
well thought out. My first contributions to OpenEmbedded many years ago
didn’t follow Debian naming, were rejected on V1 and I embarked on a new
learning curve. I’ve embraced it and never looked back.

Hi guys,

The warnings were definitely not on when I started using Yocto more than two years ago.
I have not been using debian packages, and didn't notice. I thought I was still not
using debian and that's why I am surprised about those warnings. But as I wrote, if I
ignore the warnings, nothing bad happens ...

And Tim, thank you for writing "Debian" and "OpenEmbedded" in that way ... it reassured
me ;-)

Have a good weekend. Cheers,

Ralf.

[Burton, Ross]

The check was added in August 2017 and appeared first in Rocko, so
it's possible that you stuck with an earlier release until recently.
