[PHP] PHP passthru() blocks with bash process replacement?
Hi all, I have a problem with PHP passthru() blocking when it is supposed to start a daemon and return. I have a Node.js daemon with a bash script wrapper around it. Users can call this bash script directly, but it is also used by our deployment system. Our deployment system uses Phing, and Phing uses `exec()` and `passthru()` internally to cann external programs. The bash script wrapper around my Node.js uses a bit of process replacement because my Node.js server can't directly log to syslog. Normally I'd start Node.js like this: forever -l app.log app.js But because I want it to log to syslog, I put this in the bash script: forever -l (logger) app.js The `logger` process replacement creates a file descriptor into syslog like /dev/fd/63 whose path is passed to the forever command as the logfile to use. This works great when I start the daemon using the bash script directly, but when the bash script is executed using PHP passthru() or exec() then these calls will block. If I use a regular logfile instead of the process replacement then both passthru() and exec() work just fine, starting the daemon in the background. I have created a complete working example (using a simple PHP daemon instead of Node.js) on Github's Gist: https://gist.github.com/1977896 (needs PHP 5.3.6+) Why does the passthru() call block on the process replacement? And is there anything I can do to work around it? Kind regards, -- Sander Marechal -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

My perl script is running when called by passthru() because within the body of the simple test code I have set it up to: code print Content-type: text/html\n\n; print Source ID: $source_id; /code and when I run the php with the full address to my file (abbreviated here and before for brevity): $source_id = test; passthru(/home/.../cgi-bin/passthru_test.cgi $source_id); it prints out Content-type: text/html Source ID: Which is what I expect although missing the printout for the source_id value. Is Perl set with that Tainted mode thing where it won't *LET* you use arguments from the outside world unless you at least pretend to scrub them? To test, what happens when you run text.cgi test from the command line without PHP in the picture? Re:Exec() I have tried exec and it does not seem to be working for me in terms of producing an error output. I set it up for: exec(/home/httpd/vhosts/omniomix.com/cgi-bin/passthru_test.cgi $source_id,$out,$err); and I get no printout at all. Is there something obvious that I am doing wrong? exec won't print anything at all. You have to take further action to print out $out and/or $err. Also, move the quote at the end of $err to be after $source_id As it is now, you are passing 2 more arguments with commas to your Perl/cgi script, not providing 2 more arguments to exec. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] passthru() passing variables
I dunno what 127 actually means, but the last time we saw it on this list,
it boiled down to:
You can't even run your 'sh' shell, much less Perl in that shell.
Check what's in /bin/sh and what its permissions are.
Make sure it's actually a valid shell binary, and not something bogus.
If that's not it, keep digging.
Somewhere, somehow, you've got something in permissions that is not
allowing you to run a process/binary you need.
If it's not /bin/sh, look at Perl.
If it's not Perl, check your permissions on test.cgi again.
Remember that PHP does not run as you with all your permissions - If you
can 'su' to the user PHP runs as, this could get a lot easier to test...
Check httpd.conf User directive to be certain you know what user PHP
runs as, or check ?php phpinfo()? output.

You may want to use exec first, so you can more easily capture the error

Meanwhile, odds are *REALLY* good that you're not even calling the

home/test.cgi would be assuming that home was in the same directory as
your PHP script, and even that is kinda iffy depending on where you do
this from the webserver or CLI...
I would recommend using FULL PATH to *everything* in exec (and passthru)
/full/path/to/home/test.cgi /full/path/to/any/args.txt
Also be sure to use the escapeshellargs function to make your $var data
kosher if it comes from the outside world.

1) Is
grep c=2048 c=32 c=2 /var/log/messages
a valid command? My version of grep only allows a single search pattern.
2) Do you have the necessary permissions to access '/var/log/messages' ?

That's not going to do what your thinking it will. Use egrep instead.
$ egrep 'c-2048 | c=32 | c=2' /var/log/messages
However you can do what you want with just awk, no need to involve
(e)grep.
$ cat /var/log/messages | awk '/c=2048|c=32|c-2/ {print $1 $3 $5}'

[PHP] passthru loses php posted variables
Anyone come across something like this before? I have made a little test script as follows: ? header (Content-Type: application/pdf); $command_line = /usr/bin/pdflabelseries . escapeshellcmd($_POST['labelstart']) . . escapeshellcmd($_POST['labelend']); exec (echo \$command_line\ /opt/specs/labels.txt); //passthru($command_line); ? The form takes input from a posted form with two variables, labelstart and labelend. In the above test, if I put in 'start' and 'end' as the posted variable data, the output from /opt/specs/labels.txt (writable by the http server) is: /usr/bin/pdflabelseries start end All is well and good. Now is where it heads South. I uncomment the passthru command above. The output from the script in /opt/specs/labels.txt from the same posted form with the same data entered is now: /usr/bin/pdflabelseries pdflabelseries is a C program that I have confirmed works perfectly on the command line (i.e. generates the requisite pdf file to stdout). Even if the C program fails (which it does not appear to do from the output in the httpd logs as it outputs its command line to stderr), surely php should not lose its own internal variables, especially, for a command that is executed BEFORE the passthru command. I am truly baffled. Any help appreciated.

[PHP] passthru problems generating WAVs with mpg123
I've written a little script for VoiceXML applications to generate a WAV
from an MP3 on demand:
#file wavwrapper.php
?
header('Content-Type: audio/wav');
$filename = $_GET['filename'];
$mp3dir=/var/www/mp3s/;
$playercmd=/usr/local/bin/mpg123 -m -w - -q -4 --8bit;
passthru($playercmd $mp3dir/$filename 2 /tmp/playererror);
?
I request it as wavwrapper?filename=song.mp3, and the browser reads the
MIME type properly, prompts me to play or download the song. I download
it, and save it as a WAV file. However, Mozilla downloads about 1.5M of
data, saves it all to a file, and then displays the downloaded size as
1k. And then when I try to play it back, it won't play; it's like an
empty file. Same thing happens if I try to play it directly. But if I
redirect the output of mpg123 from standard out (so it goes across the
web connection) to a file and then download the file, the file plays

is. Anyone have any ideas?

Re: [PHP] passthru problems generating WAVs with mpg123
I'm SURE you've got a good reason, but why are you wanting to generate a WAV
on demand? The loss in file quality occurs going from WAV MP3, so then
later going back to WAV would only result in a bigger file size, with ZERO
benefit in audio quality.
Just asking :)

I request it as wavwrapper?filename=song.mp3, and the browser reads the

it, and save it as a WAV file. However, Mozilla downloads about 1.5M of
data, saves it all to a file, and then displays the downloaded size as
1k. And then when I try to play it back, it won't play; it's like an
empty file. Same thing happens if I try to play it directly. But if I

[PHP] passthru()
I have a PHP script that computes the URLs to files that i need to download. Is it possible to put passthru() with wget in a while loop and donwload multiple files at one time ? Or does passthru() complete the shell command and then proceed. Any other suggestions ? thx in advance gamin. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] passthru Problems
Greetings,
I am having a small problem displaying PDF files to my users via passthru.
This is the situation: I have a bunch of PDF files on my server directory.
I show the user a listing of the PDF files they can view, and allow them to
hyperlink click on the PDF they wish to browse. When the user clicks the
link, I execute a header() and then my passthru on my PDF file. The code is
essentially:
header("Content-type: application/pdf");
passthru($pdf_file);
Now, my problem is that the title of the HTML window that pops up is of the
URL path. I want to set the title to something meaningful (like the name of
the PDF file the user is looking at). But, if I try to print a "TITLEPDF
File/TITLE" after the header, my PDF document does not show up (it shows
the raw encoding of the PDF document).
Does anyone have any suggestions to allow me to show a title on a
header/passthru page? Is there a better way to do this?
Cheers,
Jason

RE: [PHP] passthru Problems
I believe there is header called "Content-disposition: filename.pdf" which
is defined in the proper RFC. And as far as I know some browsers don't
respect it. Search the list for it, you should find allot of info.

Re: [PHP] passthru Problems
Greets,
Just to elaborate: I want my user to be able to click on a hyperlink that
points to my PDF file, and have a new window pop up, displaying the contents
of the PDF file in the browser window (without prompting if they should save
the file) as well as set the HTML TITLE tag to the name of the report.
My passthru() function works fine, when I send a header() of PDF first, and
then dump the raw PDF out. But, I cannot set any HTML properties with tags
(like TITLE); it doesn't show the PDF in PDF format then, it shows it all
raw encoded.
Hope that helps clarifying my wants and needs :-)
Cheers,
Jason

Re: [PHP] passthru Problems
You need to use a frameset to do what you want.
the problem is the browser will only launch the Acrobat control if it
receives the content type app/pdf, an html page uses the content type
text/html.
your links should point to another page that outputs something like the
following based on input of the pdf file path and name
( HTML shamelessly stolen from http://www.php4.net/ :-)
HTML
HEAD
TITLE?php echo $your_title ?/TITLE
FRAMESET rows="100%,*" frameborder="0"framespacing="0" border="0"
align=CENTER
FRAME SRC="?php echo $your_pdf_file_path ?" Name="pdf" scrolling="auto"
FRAME SRC="empty.htm" Name="invisible" scrolling="no"
/FRAMESET
/HTML
if you are using track_vars and don't have the auto globalizing of form
elements, use
$HTTP_GET_VARS[ 'your_title']
$HTTP_GET_VARS[ 'your_pdf_file_path ']
or
$HTTP_POST_VARS[ 'your_title']
$HTTP_POST_VARS[ 'your_pdf_file_path ']
depending on your form method

[PHP] passthru
On the server itself (to which I have root access) I type:
someProgram arg1 arg2 arg3
and it runs properly, returning the proper output to standard output (the
screen). I can do this from anywhere on the server (for example, from the
same directory where my php scripts are located, /var/www/html/blah), and I
can do it as the same user that apache runs as ('apache').
BUT, when I try:
?php passthru("someProgram arg1 arg2 arg3"); ?
it fails. I get no output at all. I can check that everything else is ok
by doing something like
?php passthru("someProgram arg1 arg2 arg3"); passthru("echo 'finished'");
?
which then returns just the word 'finished' to the browser.
I CAN do other things via passthru, for example,
?php passthru("man tar"); ?, and
?php passthru("ls -al"); ?
and so on. I am running php as an apache module. I am NOT running php in
'safe mode'.
Any ideas what is going wrong here?
Thanks,

Just guessing here. On our setup, PHP runs as nobody. Is there a permissions

I'm just guessing since I can't access the PHP manual and since I don't know
what program you're running here -- but perhaps "someProgram" is outputting
to stderr by mistake. That's my only guess.

[PHP] Passthru Question
Hi all,
Having a weird problem running the passthru() function on quite an old
version of PHP3 (3.0.7).
Pasted below is the php source code:
===
HTML
HEAD
TITLETape Status Check/TITLE
/HEAD
BODY
if this page is blank - that is good!
?
passthru ('/usr/bin/mt rewind',$res);
echo $res;
?
===
When I run this in a shell (as the apache user as well!) it works perfectly
as illustrated below:
===
su-2.03$ /usr/local/bin/php index.php3
Content-type: text/html
HTML
HEAD
TITLETape Status Check/TITLE
/HEAD
BODY
if this page is blank - that is good!
mt: /dev/nrsa0: Device not configured
===
When I run this in apache by accessing the URL, I get (pasted HTML from
view-source):
===
HTML
HEAD
TITLETape Status Check/TITLE
/HEAD
BODY
if this page is blank - that is good!
1
===
As you can see, its not outputting the passthru output stuff. Any ideas?

fpassthru doesn't include the code in your php code. In just dumps the file to output as it runs.
