Bug ID: 30694
Summary: The iconv program no longer tells the user which given
encoding name was wrong
Product: glibc
Version: 2.32
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: locale
Assignee: unassigned at sourceware dot org
Reporter: bruno at clisp dot org
Target Milestone: ---
When the user invokes the iconv program with an invalid FROM_ENCODING or
invalid TO_ENCODING, the error message no longer indicates which of the two was
wrong. Which leaves the user puzzled. Thus, it is a bad usability experience.
How to reproduce:
In glibc 2.32:
$ echo abc | iconv -f ARMSCII-8 -t UCS_4BE
iconv: failed to start conversion processing
In glibc 2.30:
$ echo abc | iconv -f ARMSCII-8 -t UCS_4BE
iconv: conversion to `UCS_4BE' is not supported
Try `iconv --help' of `iconv --usage' for more information.

--- Comment #1 from Bruno Haible <bruno at clisp dot org> ---
This is a regression. Most likely caused by commit
91927b7c76437db860cd86a7714476b56bb39d07.
The code for producing the useful error message is still there, in
glibc/iconv/iconv_prog.c. It is no longer reached, because __gconv_create_spec
fails before the code even gets to invoke __gconv_open.

Looks like __gconv_open loses errno.

(In reply to Andreas Schwab from comment #2)

Indeed, that's more likely than what I wrote in comment #1.
In fact, on glibc 2.31 systems I observe the same result as on glibc 2.32;
therefore most likely, the regression appeared between glibc 2.30 and 2.31,
that is, *before* commit 91927b7c76437db860cd86a7714476b56bb39d07 .
