Description Frank Hirtz 2020-12-09 15:51:23 UTC 
Description of problem:

The latest 7.9.z errata is causing issue with tcsh history in the client environment:


# Create problem
> alias postcmd '/bin/echo -n "COMMAND:"'"'"'\!#:-$:gx'"'"''

# Exibit problem

> echo 1 2 3 4 5
COMMAND:echo 1 2 3 4 51 2 3 4 5

# <==== Hit Up-arrow in your tcsh, we expect 'echo 1 2 3 4 5' to come up on prompt
> echo 1 2 3 4     <===== Note that "5" is missing!

> echo "a" 'b' "c"
COMMAND:echo "a" 'b' "c"a b c

# <==== Hit Up-arrow in your tcsh, we expect 'echo "a" 'b' "c"' to come up on prompt
> echo \"a\" \'b\' <===== Note that "c" parameter is missing! Also, quotes are escaped.

# Evidence of problem in history:
> history | tail -4
  3760 2020/12/04 7:31 echo "a" 'b' "c"
-50000000 2020/12/04 7:31 echo \"a\" \'b\'       <=== garbage “duplicate” lines without “last word”

-50000000 2020/12/04 7:35 history | tail         <=== garbage “duplicate” lines without “last word”

# Here’s the normal, expected behavior, when postcmd alias has no special quoting triggering the bug
> alias postcmd '/bin/echo -n "COMMAND EXECUTED"'
> echo 1 2 3 4 5
COMMAND EXECUTED1 2 3 4 5
> echo 1 2 3 4 5             <== Up-arrow brings up correct last command
> echo "a" 'b' "c"
COMMAND EXECUTEDa b c
> echo "a" 'b' "c"           <== Up-arrow brings up correct last command
> history | tail -5
COMMAND EXECUTED
  3765 2020/12/04 7:37 unalias postcmd
  3769 2020/12/04 7:40 alias postcmd '/bin/echo -n "COMMAND EXECUTED"'
  3770 2020/12/04 7:40 echo 1 2 3 4 5
  3771 2020/12/04 7:40 echo "a" 'b' "c"
  3772 2020/12/04 7:40 history | tail -5    <== Correctly formatted history, without corrupted “-5000000” entries

Additional details for RH analysis - 

1.	The behavior is triggered by ANY modifier (“:gx” is the one we use, but I think you can get the same bad result from a simple “:l”)

2.	Does the issue point to tcsh patch? - https://github.com/tcsh-org/tcsh/commit/955c966ffebfb6d791c289b67681f84d4a53d580

Notes: The version prior to the 7.9 patch appears to work correctly per this test (I don't know the validity of the test though; just reproducing). The 7.9 patch truncates and adds some "garbage". Upstream truncates as well on the "up arrow" (it does a "one up"->"1 2 3 4" "two up"->"1 2 3 4 5", but doesn't have the garbage.

So, it looks both of these were picked up in the patch.. some is backporting the "truncation" behavior that's upstream but the "garbage" is novel. The patch that was backported was to correct an issue in the space:

Bug 1846271 - [RHEL-7.9] tcsh corrupt history file results in rapid memory consumption until memory exhausted 

So, this behavior change looks to have been pulled in with this; we'll have to assess.
Comment 6 Jan Macku 2021-02-23 07:37:50 UTC 
Hi,

I was able to reproduce this issue and it seems like regression was introduced in tcsh-6.18.01-16.el7.

.history file shows that at the end of each command is added timestamp:

# less .history
> #+1614063515
> alias postcmd '/bin/echo -n "COMMAND:"'"'"'!#:-$:gx'"'"''
> #+1614063520
> echo 1 2 3 4 5#+1614063612
> #+1614063612
> echo 1 2 3 4 5#+1614063647

Strange is that when I was upgrading from tcsh-6.18.01-15.el7 to newer package I wasn't able to reproduce the issue.

I will continue with debugging.

Comment 7 Jan Macku 2021-02-23 09:30:33 UTC 
Hi,

I tried to reproduce it again but this time I removed .history file first and then I wasn't able to reproduce it issue.

[root@localhost ~]# rm .history 
> rm: remove regular file ‘.history’? y
[root@localhost ~]# tcsh
[root@localhost ~]# alias postcmd '/bin/echo -n "COMMAND:"'"'"'!#:-$:gx'"'"''
> alias postcmd '/bin/echo -n "COMMAND:"'"'"'alias postcmd'"'"''
[root@localhost ~]# echo 1 2 3 4 5
> COMMAND:alias postcmd1 2 3 4 5
[root@localhost ~]# echo "a" 'b' "c"
> COMMAND:alias postcmda b c
[root@localhost ~]# history | tail -4
> COMMAND:alias postcmd     1	4:11	alias postcmd '/bin/echo -n "COMMAND:"'"'"'alias postcmd'"'"''
>      2	4:11	echo 1 2 3 4 5
>      3	4:11	echo "a" 'b' "c"
>      4	4:11	history | tail -4
[root@localhost ~]# rpm -q tcsh
> COMMAND:alias postcmdtcsh-6.18.01-17.el7_9.1.x86_64

Then I exit from tcsh and try it again without deleting .history and everything works as expected.

History in tcsh was always causing issues.

The last Z-stream release should fix some issues with corrupted history. So I would highly suggest to get rid of corrupted history if possible and update to latest tcsh release (tcsh-6.18.01-17.el7_9.1).

Hi Jan,

I'll check that with my case, have the client run through it and let you know. Thanks for looking into this.

This all seems to work, but I was initially seeing the issue where the timestamp is appended to the command in the history file:

That was just on my initial setup and I didn't have a .history, but when I tried to reproduce in a more controlled manner, the issue went away. I'm not quite sure what the relevant variable is here that does this. I'll see about reproducing some more to understand it and check with the client on reproducing in their environment.

Stepping back and reinstalling, I can reproduce this with a "clean" history:

This was removing the previous tcsh install, deleting the ~/.history, installing the current version, and running the reproducer flow. When I continued with the install, as noted, things get murkier in that this doesn't happen reliably, but the simple install->run appears to show it. There's no ~/.history, so it's not latent corruption... in the file at least.

Hello Frank,
I'll have a look into in next week. I'll keep you updated.

Thank you for reproducer.

Hi Frank,
I was able to reproduce the issue.

RHEL 7.9:
---------
> [root@localhost ~]# rpm -qa tcsh
> tcsh-6.18.01-17.el7_9.1.x86_64
> ...
> [root@localhost ~]# history | tail -10
> COMMAND:history | tail -10     1	2:23	alias postcmd '/bin/echo -n "COMMAND:"'"'"'\!#:-$:gx'"'"''
>      2	2:23	echo 1 2 3 4 5
> -50000000	2:23	echo 1 2 3 4
>      3	2:23	echo "a" 'b' "c" d
> -50000000	2:23	echo \"a\" \'b\' \"c\"
>      4	2:24	history | tail -10
> -50000000	2:24	history | tail

Fedora Rawhide:
---------------
> [root@localhost ~]# rpm -qa tcsh
> tcsh-6.22.04-1.fc35.x86_64
> ...
> [root@localhost ~]# history | tail -10
> COMMAND:history | tail -10     1	2:30	alias postcmd '/bin/echo -n "COMMAND:"'"'"'\!#:-$:gx'"'"''
>      2	2:30	echo 1 2 3 4 5
>      3	2:31	echo "a" 'b' "c"
>      4	2:32	history | tail -10

In upstream (Fedora) the history looks cleaner, but when I hit the upper arrow, then the last word is always missing (same behaviour as in RHEL 7.9).

I'll continue debugging this issue.

Hi Frank,
I don't think this is regression, if so, then it's a very old one.

I tried RHEL 7.6 and it behaves the same as RHEL 7.9 and Fedora rawhide.

Regards
Jan
