Help with STDIN and multiple source of input
Hi,
I'm confused about exactly what is the problem I'm facing so I'll explain what I am trying to achieve hoping someone can help me out.
MySQL has a command line interface you can call like this (let's say my user is "user" and my password is "1234" and my database is db)
mysql -u user -p1234 db < a.sql
Specifying the password on the command line is bad so you can call the same command this way and you will be prompted for it interactively
mysql -u user -p db < a.sql
It works well, no problem with this...
Now, I'm trying to do the same thing in PHP using proc_open(
http://us3.php.net/manual/en/function.proc-open.php )
What I don't get is that is there 2 stdin ? one for the file and one for the interractive prompt ?
Doing this works like a charm (sending the .sql file over stdin):
~~~~~~~~~~~~~~~~
$hProcess = proc_open(
"mysql -u user -p1234 db",
array (
0 => array("pipe", "r"), // stdin
1 => array("pipe", "w"), // stdout
2 => array("pipe", "w") // stderr
),
$a_Pipes
);
if (is_resource($hProcess)) {
//sending sql content on on STDIN
fwrite($a_Pipes[0], "file_get_contents('a.sql')");
fclose($a_Pipes[0]);
fclose($a_Pipes[1]);
fclose($a_Pipes[2]);
$iReturn = proc_close($hProcess);
~~~~~~~~~~~~~~
Doing this works like a charm (sending the password over stdin but sending the query on the command line):
~~~~~~~~~~~~~~
$hProcess = proc_open(
"mysql -u user -p db -e "select 'foo' from DUAL"",
array (
0 => array("pipe", "r"), // stdin
1 => array("pipe", "w"), // stdout
2 => array("pipe", "w") // stderr
),
$a_Pipes
);
if (is_resource($hProcess)) {
//sending password on STDIN
fwrite($a_Pipes[0], "1234\n");
fclose($a_Pipes[0]);
fclose($a_Pipes[1]);
fclose($a_Pipes[2]);
$iReturn = proc_close($hProcess);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
But how can I send both the password AND the sql content ?
I tried to write both the password and the sql file on stdin -> didn't work
I tried to send just the password on stdin and send the sql file using "<" in the command didn't work
I tried to pipe a cat on the sql file to mysql while sending the password over stdin and it didn't work...
I tried to create another piped stream #3 to write to it, didn't work...
How is mysql able to get valud from both interractive AND stdin ?
I've read posts about writing password to environment variables or text file, but I'm looking for a safer approach...
Any help would be appreciated.
Thanks in advance

Welcome to LQ!
Please place your code snippets inside [CODE]...[/CODE]
tags for better readability. You may type those yourself or click the "
# " button in the edit controls.
I have never used PHP's proc_open(...), but from your description and a quick look at the manual page linked, I think the way to do that would be to use a "file" element in the descriptorspec array.

1 => array("pipe", "w"), // stdout
2 => array("pipe", "w") // stderr
3 => array("file", "/path/to/sql/file", "r") // file
),
$a_Pipes
);
if (is_resource($hProcess)) {
//sending password on STDIN
fwrite($a_Pipes[0], "1234\n");
fclose($a_Pipes[0]);
...
}
That may work the same way, with the mysql client prompting for, and receiving the password from STDIN (file descriptor 0), then reading from the file (file descriptor 3).
If it is not that simple, look through the manual or for examples of using the file argument to the descriptor array. You may have to write to the file pipe, but as you can give it a filespec and open for reading it seems to me that it should be ready to go as is.
Good luck!

Tell no-one, but PHP does have built-in Mysql support, there is no point in calling 'mysql(1)' as external program from PHP.

I had the same thought, but as the OP seems to want to be prompted for password and to read from an existing SQL file which may not be easily parsed into single queries, proc_open may be useful.
Perhaps the OP could tell us more about what their actual goals and constraints are as well.

Well, here is a question worth examining:

Hi Thanks for the info. I tried to do it, it "works" meaning there is no error, but the MySQL process "hangs" waiting for input like if I was in regular cli mode.
So I'm not sure how a process on linux "knows" if it needs to read from #0 or #3, but here even if #3 is a handle to a sql file, MySQL doesnt try to read from it

With your comment, I tried this:
PHP Code:
$hProcess = proc_open ( "mysql -u user -p db < $sTempFile " , 0 => array( "pipe" , "r" ), // stdin 1 => array( "pipe" , "w" ), // stdout 2 => array( "pipe" , "w" ), // stderr 3 => array( "file" , "/dev/tty" , "r+" ) // stderr ), $a_Pipes );
I was thinking I could send the password on descriptor 3 but I'm getting an error proc_open(/dev/tty): failed to open stream: No such device or address

In that trace, I sent the password interactively, and the sql file in stdin like this
mysql -u user -p db < a.sql

Hi,
I am building a web interface so that level 1 technicians can restore customer backups to test database to reproduce problems or help customers by trying stuff first.
Usually, I run the restore manually form the command line like this
mysql -u user -p db < a.sql
I don't want to give them ssh access so I'm trying to reproduce this in a Web interface using php.
I don't want the password to be visible if someone is doing a "ps -aux" and I would prefer not writing the password in clear text in a text file like other posts suggest.
And yes, I know PHP can connect to mysql, but files I need to restore are several gigs, it's easier to just redirect the sql file to the mysql binary.
Thanks

Restoring several gigs database backup may take resources and time. I would set up a cron job for this.

Thanks for your comment, but discussion is moving away from my need... I just need someone that understand how the MySQL cli client is able to retrieve the password from tty and the source file from stdin.
From there, I'll try to reproduce the functionnality using proc_open with multiple file descriptors
Thanks

Instead of reading file via stdin, you could use a source file query?

One of the key principles of working with "child processes that you do not own" is ... "do not attempt to do their work for them." For instance, the MySQL command-line interface program already has a source filename subcommand. Therefore, you should simply arrange to use this subcommand to "tell the child what to do." Don't do its thinking for it.

Thanks, it worked...
I'm sending the password to stdin but I'm using -e "source /tmp/a.sql" on the command line to load the file so I don't need to try to send it to stdin...
I'm still curious about how it works, but at least it works.
Thanks to all
