Subject: PHP refuses a command line background execution (& or cron)

Date: Sun, 19 Dec 2004 20:58:21 +0100

[Message part 1 (text/plain, inline)]

Package: php4-cli
Version: 4.3.9-2 (also in 4.3.9-1)
Severity: important

php4-cli refuses to run in background. It will work neither with a '&' background execution order nor with cron.

Just try at the command line:
>php -v
It works fine.

Now try:
> php -v &
It will answer:
[1] 390
[1]+ Stopped        php -v
and the status of the process goes to T. It will restart only with the 'bg' command. 

cron does not work as well.

Of course if any PHP script ('php toto.php &' or './toto.php &') is called the same way, it gets stopped as well.


I am using Debian GNU/Linux with kernel 2.4.18-bf2.4. php4-common is 4.3.9.2 (the problem also exists with 4.3.9.1 - I have upgraded because of this).

Subject: php4-cli: Problem caused by using libedit!

Date: Thu, 23 Dec 2004 10:55:12 +0100

Package: php4-cli
Version: 4:4.3.10-2
Followup-For: Bug #286356


The problem seems to be the using_history() function of libedit, a readline replacement. I've posted a bug report for them 
(http://sourceforge.net/tracker/?atid=118314&group_id=18314&func=browse).
Readline does not have this problem, so if php4 would just be configured with --with-readline instead of --with-libedit, our problem would be solved. (Why is 
the non-GNU libedit used anyway?)

Licensing issues.  Readline is GPL, and we can't link with GPL libraries
without violating their license.

Subject: Possible progress on the root cause of this

Date: Fri, 28 Jan 2011 09:36:31 -0800

This seems to be the same bug as has been noted here in Ubuntu:

https://launchpad.net/bugs/322214

I recently spent some time tracking down what happens in libedit vs.
readline and it seems that libedit always takes control of stdin during
php's module init phase call to using_history(), even if later it
decides that it shouldn't enable editting because stdout is not a
terminal.

I forwarded a patch along to the netbsd tech-userlevel mailing list,

http://mail-index.netbsd.org/tech-userlevel/2011/01/26/msg004486.html

It can also be seen as a patch to the ubuntu package here:

https://code.launchpad.net/~clint-fewbar/ubuntu/natty/libedit/fix-tty-handling/+merge/47591

I don't think it would be wise to patch libedit without upstream
accepting said patch. But the initial reaction is positive.

Just as an FYI, the patch has been uploaded to Ubuntu precise, and I
think is worth pulling into Debian's version of libedit as well. Its no
surprise that NetBSD isn't responding to the fix since the problem only
affects Linux users.

We can, but you are barking up the wrong tree here.  You need to speak
with libedit maintainer.

Just FYI: I am going to NMU this bug as soon we are unfrozen again.
The fix has been available for two years now and the interactive mode
is requested feature by many of our PHP users.

Funny, it would actually help if you close the fixed bugs...

libedit (2.11-20080614-4) unstable; urgency=low

  * Merge 2.11-20080614-3ubuntu2
    - Fix libdir in libedit.pc to match multiarch installation paths.
    - libedit/tty.c: grabs controlling terminal even when output is a non
      tty, causing things like php | less to mis-function. Patch changes
      this behavior to work more like readline. (LP: #322214)
