Description Eugene Kanter 2020-02-25 00:51:12 UTC
Description of problem:

After recent changes in tcsh the command history -S ignores merge directive and simply writes out current shell history, overriding .history file.

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. make sure there is a line as below or similar in .cshrc
set savehist = (1024 merge lock)
2. open two terminal windows for user which set to use csh or tcsh
3. open .history in gedit.
4. start from clean .history, preserve original if needed.
5. run several different commands in one shell, use history -S as last one.
6. observe command list written in .history
7. run history -S in second shell.

Actual results:
.history is completely erased except for last history -S.

Expected results:
both shells command list is merged into .history

Additional info:
tcsh-6.20.00 from RHEL v8 works correctly.

Just checking if anyone is looking at this and/or upstream bug needs to be filed to proceed.

Comment 2 Jan Macku 2020-05-26 11:05:52 UTC
I'm sorry about delay, due to time reasons I wasn't able to have a look at this issue.

I'll contact upstream and let you know about any updates.


Comment 3 Eugene Kanter 2020-06-16 02:22:10 UTC
Any updates from upstream? Fedora 32 exhibits the same problem.

Comment 4 Jan Macku 2020-06-16 06:34:40 UTC
no updates from upstream. I'm sure they'll get to it at some point.

I'll let you know.

Thank you for your patience

Comment 5 Eugene Kanter 2020-08-15 03:07:48 UTC
Was is the upstream bug number?

Comment 6 Eugene Kanter 2020-09-11 14:29:38 UTC
Almost three months later - any updates?

Comment 7 Jan Macku 2020-09-14 06:48:49 UTC
still no updates from upstream.

May I ask you, are you using NFS for your home directory?
If not, I thing that removing 'lock' keyword from 'set savehist = (1024 merge lock)' might help.


Comment 8 Eugene Kanter 2020-09-14 19:33:40 UTC
What is relevant upstream bug?

Comment 9 Eugene Kanter 2020-09-14 19:34:56 UTC

I am not using NFS but lock keyword is for preventing multiple shells from stepping on each other while updating .history file as far as I can see.

Comment 10 Eugene Kanter 2020-11-18 19:40:20 UTC
6.22.03 supposedly resolved this regression.

Comment 11 Eugene Kanter 2020-11-18 23:32:18 UTC
It appears that one line fix has been available since February:


Comment 12 Jan Macku 2020-11-19 10:00:51 UTC
thank you for your investigation.

Upstream released new version: https://github.com/tcsh-org/tcsh/releases/tag/TCSH6_22_03

I'll rebase tcsh version in rawhide, f34 and f33 to this version.
