[Debugging output] Make remote packet truncation length adjustable
While debugging, i felt the need to adjust the truncation length of remote
packets so i could see more or less data as needed. The default is currently
set to 512 bytes.
This patch makes this option adjustable through the new "set debug
remote-packet-max-chars" command. It can be set to unlimited if we want to
completely disable truncation.
Update on v5:
- Adjusted function and variable documentation, NEWS entry and GDB manual.
gdb/ChangeLog:
2019-11-25 Luis Machado <luis.machado@linaro.org>
* NEWS (New Commands): Mention "set debug remote-packet-max-chars".
* remote.c (REMOTE_DEBUG_MAX_CHAR): Remove.
(remote_packet_max_chars): New static global.
(show_remote_packet_max_chars): New function.
(remote_target::putpkt_binary): Adjust to use new
remote_packet_max_chars option.
(remote_target::getpkt_or_notif_sane_1): Likewise.
(_initialize_remote): Register new remote-packet-max-chars option.
gdb/doc/ChangeLog:
2019-11-25 Luis Machado <luis.machado@linaro.org>
* gdb.texinfo (Debugging Output): Document set debug
remote-packet-max-chars.
