We look at every single filed bug report and pull request. (Sometimes
we're slow to act on them though, as we're not that many developers who
work on random bugs and PRs.)
The world is big and diverse and we have a lot of users who are using
systems or curl features that a large portion of the world does not.
When you experience bugs on a niche platforms or with features not used
widely, there's a chance that A) you're alone to report and experience
the bug and even B) there's no regular developer around who's using it.
I'm convinced curl on EBCDIC is one such niche with few devlopers. We
don't get many bug reports about EBCDIC, which I believe is because we
don't have many users using EBCDIC...
We do have a travis build making sure CURL_DOES_CONVERSIONS builds work
and are functional, but that's not using EBCDIC. Not enough test and CI
infrastructure for something as impactful as EBCDIC will quite naturally
lead to bugs getting introduced over time.
Thank you, Daniel. It's clear to me that EBCDIC support is a niche and
that I need to become active myself for getting things fixed, but it's
good to know that bug reports about EBCDIC problems are heard.
1) subjectAltName check for HTTPS connections
In lib/vtls/openssl.c in function verifyhost() two strings with
different encodings are passed to Curl_cert_hostcheck(), causing the
check to always fail. I have a potential fix for this.
Please file a PR!
Will do.
2) ASCII-based character classification

Exactly, but as the comment says: it's next to impossible to work on
this and get it right without actually being able to test and verify it
on such a system. Please file a PR for a fix that makes it work for you!
I will try to come up with a pull request as well, but I need some
mentoring for this. The easiest way to get a working library on EBCDIC
again would be to conditionally compile the old macros that were used
before the introduction of curl_ctype.c, as you also mentioned in one
comment in pull request #2269.
This worked well for us before. Would that be an acceptable solution?
If those are the only problems, I consider things to be in a pretty
decent shape still!
That is certainly true, and it's amazing how well curl works on EBCDIC
platforms in general!
