HEADS UP: Rebasing to Readline-7.0 in rawhide

[Siteshwar Vashisht]

Hello,

Readline-7.0 was released few months ago and I have rebased it in rawhide to version 7.0. I have created a compatibility package compat-readline6 to avoid breaking any existing applications.

Update to readline-7.0 caused a build failure with gdb that was fixed by this commit [1].

I am providing abidiff report for the changes between readline-6.3 and readline-7.0 :

ELF SONAME changed
Functions changes summary: 2 Removed, 2 Changed (1 filtered out), 17 Added functions
Variables changes summary: 0 Removed, 1 Changed, 15 Added variables

SONAME changed from 'libreadline.so.6' to 'libreadline.so.7'

2 Removed functions:

'function void _rl_audit_tty(char*)'    {_rl_audit_tty}
  'function void replace_history_data(int, histdata_t*, histdata_t*)'    {replace_history_data}

17 Added functions:

'function void _hs_append_history_line(int, const char*)'    {_hs_append_history_line}
  'function void _hs_replace_history_data(int, histdata_t*, histdata_t*)'    {_hs_replace_history_data}

2 functions with some indirect sub-type change:

[C]'function bool _rl_print_color_indicator(char*)' at colors.c:123:1 has some indirect sub-type changes:
    parameter 1 of type 'char*' changed:
      in pointed to type 'char':
        entity changed from 'char' to 'const char'

[C]'function int rl_restore_state(readline_state*)' at readline.c:1405:1 has some indirect sub-type changes:
    parameter 1 of type 'readline_state*' has sub-type changes:
      in pointed to type 'struct readline_state' at readline.h:894:1:
        type size changed from 1536 to 1792 bits

    type of variable changed:
     type name changed from 'int' to 'unsigned long int'
     type size changed from 32 to 64 bits

I would be happy to help if any package maintainers need my help with updating to readline-7.0.

insight
ipmitool
kawa
ktechlab
libgda

socat
sqlcipher
tcl-tclreadline
telegram-cli
torque
v8-314
xmlrpc-c

This are the packages in koji which are still linking to
libreadline.so.6.
