When 2.6.0 was released some people reported that the third-party `rbenv`
and `pyenv` commands were incorrectly depending on our `setenv` function
not behaving exactly like the csh command of the same name. Specifically,
our version had a bug. It allowed more than one value. It no longer
does so after it was rewritten so that the three auto-split vars were
correctly handled.
See issue #4103
Per discussion in PR#3998 to review adding a `--filter` flag to `string
replace` rename the same flag in the `string match` subcommand to avoid
confusion about the meaning of the flag.
Discussion in issue #3295 resulted in a decisions to rename the
functions --metadata flag to --details.
This also fixes a bug in the definition of the short flags for the
`functions` command. The `-e` flag does not take an argument and
therefore should not be defined as `e:`. Notice that the long form,
`--erase`, specifies `no_argument`. This discrepency happened to work
due to a quirk of how the flag parsing loop was written.
- Error out if anything that is not a PID is given
- Otherwise background all matching existing jobs, even if not all
PIDs exist (but print a message for the non-existing ones)
Fixes#3909.
In the process of fixing the issue I decided it didn't make sense to
have two, incompatible, ways of converting variable strings to arrays.
Especially since the one I'm removing does not return empty array elements.
Fixes#2106
This is a terminal feature where pastes will be "bracketed" in
\e\[200~ and \e\[201~.
It is more of a "security" measure (since particularly copying from a
browser can copy text different from what the user sees, which might
be malicious) than a performance optimization.
Work towards #967.
ncurses since 6.0 sends the "E3" sequence along with "clear", even for
just `clear` or `tput clear`. This deletes the scrollback buffer which
is usually not what you want.
Fixes#2855.
This puts a hard upper bound of 10 MiB on the amount of data that read
will consume. This is to avoid having the shell consume an unreasonable
amount of memory, possibly causing the system to enter a OOM condition,
if the user does something non-sensical.
Fixes#3712
