Just to confirm, this is still present as of php5-cli 5.3.3-1ubuntu3
I've taken a good long look at this, and I am 99.9% sure that this is a
problem with libedit..
#include <stdio.h>
#include <histedit.h>
int main(int argc, char *argv[])
{
using_history();
printf("Some interesting info\n");
return 0;
}
This program, compiled with 'gcc test.c -ledit -o test'
Will produce the exact same effect when piped to less.
using_history() is called in the init function of the readline extension
at line 168 of ext/readline/readline.c
The reason this didn't break in the standard PHP build is most likely
that libedit wasn't used, as readline is an optional module.
I reported it here:
https://sourceforge.net/tracker/?func=detail&aid=3044367&group_id=18314&atid=118314
But that tracker appears to be dead. Also sent report to the Debian
Maintainer, and will mark it as also affecting libedit. I tested it with
the GNU readline library's using_history(), and that did not exhibit the
same problem.
One possible workaround is to build readline as an extension, and not
load it by default. I suspect though that any packages that have php
scripts that need/want readline would be fairly broken then. Another
method is to have the readline extension make sure it lets go of the
terminal if libedit is used.
