RE: [PHP] php session_start dead lock
We ran the checks and found no problems with the disks. All disks are accessible, there are no I/O errors or disk access errors. What has me bewildered is this started happening quite recently. If it's not hardware, then perhaps a new usage pattern is revealing a flaw in our php session handling code. I have a suspicion it may be related our use of AJAX. When a page is loaded in the browser we invoke PHP scripts asynchronously while another page may still be loading, which could cause two threads at the same time to want to lock the same session file in /var/tmp. I am wondering if such a thing could result in a perpetual deadlock in php_flock when invoked from session_start. We have a PHP script loading a page and from the page we have a javascript invoking another php script via Ajax which posts data that refreshes content dynamically via the DOM. The script that is invoked via AJAX is not calling session_start, it is invoking session_id() only. Yet it works. It does reuse the same session id as we establish context with a database using it. I am going to play with this and see if adding session_start before session_id() in the php script that is executed via AJAX may be involved. When you said, there could be other things - please share some other ideas. perhaps others have seen this? as well as if anyone thinks this theory has validity. thank you. -Original Message- From: paras...@gmail.com [mailto:paras...@gmail.com] On Behalf Of Daniel Brown Sent: Thursday, June 23, 2011 3:42 PM To: Zaccone, Warren Cc: php-general@lists.php.net Subject: Re: [PHP] php session_start dead lock On Thu, Jun 23, 2011 at 15:27, Zaccone, Warren wzacc...@telcordia.com wrote: We recently started experiencing a problem on our server (httpd 2.2.19, PHP 5.3.6) where all of the apache child processes hang in PHP code and no longer process requests.

[PHP] session_start() may take 5 seconds :(
My web-app sometimes takes just over 5 seconds to execute a single start_session() statement. No other connections are open to the site when i hit the button that makes this happen, the session is just 78kb on a local disk, and it's consistent behavior. So far, it only happens when i request certain page content via AJAX, but I'd like to get rid of it asap. Strangely, some other page content requested under the same conditions via the same pipeline returns without the delay. It doesn't do anything differently except the business code, and the session is opened in app-wide generic code that is executed before the business code is executed. The very timing with microtime() happens before the business code executes. I've already googled, but haven't found anything useful. It's on a windows box (latest wampserver) and due to a ubuntu firefox limitation i can't test on linux at the moment, nor run strace on it :( -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Does the underlying engine in PHP provide the otherwise missing tag? the tag is not missing as such - the tag denotes the end of string that php parses - it's quite logical to assume that the end of a file means the same thing (especially when you consider that any file you include/require must specify '?php' to 'awaken' the php parser) Does the described problem only happen with FF on Mac or does it affect other browsers on other OSes? I have never seen this problem effect just one browser on on platform - afaic it's a general problem that effects all browsers - you can't send out HTTP headers after HTTP content ... now it maybe that some browsers these days see fit to ignore white space before the headers (or maybe just ignore a \n) but I doubt it ... honestly I can't see how php would even send the headers after the \n had been output ... either you error logging level is too low, your not reading the error log or you have error suppression on the header() function (.e.g @header()). all of these would give you the incorrect notion that the header function was working, all of these are bad practice. you also mentioned you changed the code when trying to test it on another machine - don't do that, test one thing at a time. anyway problem solved, preventative knowledge aquired, onto the next hurdle :-) Ulex -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] session_start problems with FireFox on Mac
Hey... thanks for the replies. I installed the headers feature that Richard suggested and found that no headers were output. I started to transfer my php to another site to see if the problem replicated and I wasn't able to recreate the problem. It turns out that I require a file before the session_start that had one stupid character of whitespace at the end of it. When I transferred the php to recreate the problem, I replaced the require call with the actual code - eliminating the whitespace at the end of the file, so the problem didn't replicate. It took me a long time to figure out that was the problem. What a killer! To illustrate my php goes like this: index.php = ?php code code require index2.php code ? index2.php ?php code code code ? whitespace character The whitespace character is actually just an extra newline \n at the end of the file. So that gets output to the browser before the headers and apparently doesn't lock up any browsers except FireFox on a Mac. Thanks for the help.

[PHP] session_start is slow occasionally
Hi i have a site that is relatively high loaded (~20 reloads/sec) and i am
trying to optimize it.
So i have started timing sections of the php scripts to find out which is the
slowest so i optimize it first. I write the times to a database( timings are
done on the live server). So now when a user reloads the page (timings are set
on only one of the pages) i write to the database how long it took and how long
different sections take. That way i noticed thar occasionally that page takes
extremely long to generate (there are occasions of 300sec), but generally it
takes between 0.05 and 0.2 sec to generate. I started moving the sections to
determine where the problem lies and it turned out that these three lines take
that long from time to time:
ini_set(session.gc_maxlifetime, 2400);
session_name('x');
session_start();
I measured each of them and seems that session_start is the problem(had a few
~11 sec loads, but not something this big yet, of which ~10.5 is taking
session_start)
Does anyone know what is going on? Sessions are stored in /tmp/sessions/ which
is 100MB ram drive and at the moment when this occurs it was ~68% used with
~12000 files in it.
And i have one more question. How does apache handle high loads? Does it
suspend the php script when there are no resources and resume it when it frees
some, or it doesn't pick it up at all?
Thank you

My suggestion is check the php source for what session_start does. Maybe
it scans the directory to make sure it's going to generate a unique id
and even though it's on a ram drive it's taking a while because of the
number of files already there.
That's just a completely wild guess though ;)

Yes, I believe you need to elaborate more on your objectives for the
code and what exactly you mean by the file being written twice. From the
code snippet above, it seems as though you are just going to overwrite a
file and destroy it's contents, not write to it twice.

[PHP] session_start(), Pragma and Cache-control headers
Hello,
I'm working on a downbload script which serves M3U
files (Winamp playlist files) through a PHP file
like this :
somepath/download.m3u.php?id=2
Then in the PHP script I generate the M3U file, and
serve up the headers I want. Swell so far, but a
little problem appears.
The downloads are for members only, and therefor I
need to check if the user is logged in, I do this by
sessions and therefore I add a session_start() at the
start of my file. When I do this some headers are
added to the file, namely :
Set-Cookie: PHPSESSID=xxx; path=/
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0,
pre-check=0
Pragma: no-cache
Theese headers are not needed, and I dont want them
either, exept I cant seem to get rid of them since I
need the session_start() in the beginning of the file.
Sure, I could wish for a function unset_potensial_header(pragma);
I guess there are no way to remove theese unwanted headers?
Yesterday I had to give up another problem, but luckily I
found the answer here : http://bugs.php.net/bug.php?id=33057
So to sum it up :
How can I remove the Cache-Control and Pragma headers?
And Im not looking for this answer :
header('Pragma: ');
header('Cache-control: ');
The headers are still sendt, exept they are empty, doesnt look
like a nice sollution for a production environment.
Kind regards,

Re: [PHP] session_start(), Pragma and Cache-control headers
I solved the problem after a while, seems it had been
reacently debated in the bug pages within php, to remove
headers which are added by the session_start(); you can
add the following :
ini_set('session.use_cookies', false);
session_cache_limiter('');
Kind regards,

Subject: [PHP] session_start(), Pragma and Cache-control headers
Hello,
I'm working on a downbload script which serves M3U
files (Winamp playlist files) through a PHP file
like this :
somepath/download.m3u.php?id=2
Then in the PHP script I generate the M3U file, and
serve up the headers I want. Swell so far, but a
little problem appears.
The downloads are for members only, and therefor I
need to check if the user is logged in, I do this by
sessions and therefore I add a session_start() at the
start of my file. When I do this some headers are
added to the file, namely :
Set-Cookie: PHPSESSID=xxx; path=/
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0,

RE: [PHP] @session_start generates a new session_id
It still doesn't work :(... When I try to destroy the session without asking
if there's a session_id, it gives me a warning, I fixed it with the
if(session_id()) but still, when the user logs in again with a different
profile, in the same browser window, the profile that is loaded is the
previous one...
Here I copy the logout.php code:
?
$_SESSION['validlogin']=;
$_SESSION['username']=;
$_SESSION['password']=; //destroy the sessions array
$_SESSION = array();
//destroy the session
if(session_id()){
session_destroy();
}
?
And the code that runs when the user logs in:
?
$username=trim($_POST['user']);
$password=trim($_POST['pwd']);
if(session_id()){echo('Error, please contact tech support'); exit();}
if(validateuser()){
session_start();
$_SESSION['validlogin']=true;
$_SESSION['username']=$username;
$_SESSION['password']=$password;
}
...
?
Any ideas why the session variables get set to their first value after
starting the session for the second time? Should I create a different
session id each time?
Tia, Lizet

RE: [PHP] @session_start generates a new session_id
Hello Greg,
Thanks for reply, I did try
ini_set ( session.auto_start, 1); and it set the session.auto_start to
On on my configuration, however the rest of the users on that server had
auto_start off.
This didn't solve the problem, should I try to access .htaccess? I presume
it will affect all the sites on that server, right?
The problem continues, I run the logout script each time the user leaves the
admin site:
?
$_SESSION['validlogin']=;
$_SESSION['username']=;
$_SESSION['password']=;
unset($_SESSION['validlogin']);
unset($_SESSION['username']);
unset($_SESSION['password']);
session_unset();
print(username=.$_SESSION['username']);
print(password=.$_SESSION['password']);
if(session_id()){
session_destroy();}
?
And when the user tries to enter the admin panel again and log in, the
following script runs:
?
...
session_start();
$_SESSION['validlogin']=true;
$_SESSION['username']=$username;
$_SESSION['password']=$password;
?
However when the user logs out and the first script runs, if that user tries
to log in again with a different account, the session is started, but the
username and password variables take the first user's values, they're not
overriden.
Any idea?
Thanks a lot in advance.
Lizet

[PHP] @session_start generates a new session_id
Hi, I made an update to Apache/1.3.31 (Unix) PHP/4.3.9 and before this everythings works fine. The problem is that a following page generates a new session stored under the session.save_path and the stored variable e.g. $_SESSION['SESS_CUS'] is not valid anymore due the SID entry. On both pages I use this to start: @session_start(); session_name(userauth); $_SESSION['SESS_CUS'] = $user_id; to verify the $USER_ID in conjunction with the actual valid session value. I tried already a form with a hidden field to overgive the session which works fine in the former version: form method=post action=\./MyFILE.php?USERNAME=$realnameUSER_ID=$user_id\ INPUT TYPE=\hidden\ NAME=\session_name();\ value=\session_id();\ INPUT TYPE=\submit\ VALUE=\Login for the board\ /form But this doesn't work anymore ... The new LAMP system generates everytime after calling @session_start(); a new session. Either on the same page or a following one. How can I prevent this behavior by using the PHP session management function ? -- Best Regards, Mark -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Session_Start Problem (Fatal Error)
I'm using Mambo Open Source CMS to run a site I'm building, and seem to have a problem logging into the Administration Tool. It comes up with: Fatal error: session_start(): Failed to initialize storage module. in /home/hetbweb/public_html/administrator/index.php on line 64 I've looked at various things that could cause this, and finally contacted my server support who said: It's a PHP bug which they still havent fixed as of yet, as soon as the fix becomes available we will update PHP. It may be worth looking on the mambo forums as there may be a patch to resolve this for your script. Does anyone know about this, and if so, is there a fix or work around or anything?

[PHP] session_start in php 4.3.6
Hi All my web sites suddenly stopped working after my ISP installed the newer php 4.3.6 released. The problem is when calling the session_start() function. It seems that the warning message saying that the session has already started and that the function will be ignored makes the php script stop at this point although it is a warning.

This worked perfectly in php 4.3.4. What should I do to be compatible with php 4.3.6? This is because your ISP has likely set session.auto_start = 1 in php.ini Either have the ISP set it to 0 or remove all session_start calls from your scripts to eliminate the warnings.

[PHP] @session_start()?
I noticed this notation in one of the PEAR packages @session_start()? What is the purpose of the '@' sign? Thanks Brandon
[PHP] session_start
I would appreciate some help to save my few remaining hairs. I have an administrative program starting with session_start() It starts by asking for userid and password. It's been working for over a year with no problems. Within the last couple of day something strange has been happening. Frequently, but not always, at the bottom of the output is the message: Warning: Unknown(): The session id contains invalid characters, valid characters are only a-z, A-Z and 0-9 in Unknown on line 0 Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0 when it re enters the program I get: Warning: session_start(): The session id contains invalid characters, valid characters are only a-z, A-Z and 0-9 in /usr/local/include/eg-admin-index.inc on line 7 Taking a shot in the dark I put session_name(); before session_start() It seems to have fixed the problem but I have no idea why. Can anyone shed some light on: 1. what caused the problem to start? 2. how session_name() is fixing the problem? Thanks Urb

[PHP] Session_start() problem
Hey all, I'm working out of a book teaching myself PHP4 here and I've
got this code from a login web page...
[begin code]
session_start();
if(!isset($userid)) {
login_form();
exit;
}
else {
session_regisister(userid, userpassword);
if(!$username) {
session_unregister(userid);
session_unregister(userpassword);
echo Authorization failed. .
You must enter a valid userid and password
combo. .
Click on teh following link to try
again.BR\n;
echo A HREF=\$PHP_SELF\login/ABR;
echo If you do not have login, please contact
Operations to obtain one.br\n;
exit;
}
else echo welcome, $username!;
}
[end code]
The page puts up a for with fields for username, password etc. nothing
crazy, but when I open the page I get the following error displayed
(before data is entered into the form and subitted).
[begin error]
PHP Warning: session_start():
open(/tmp\sess_d7d909aa6e85cf5489a50f6e42f03b12, O_RDWR) failed: No such
file or directory (2) in c:\inetpub\wwwroot\auth_user.php on line 54 PHP
Warning: Unknown(): open(/tmp\sess_d7d909aa6e85cf5489a50f6e42f03b12,
O_RDWR) failed: No such file or directory (2) in Unknown on line 0 PHP
Warning: Unknown(): Failed to write session data (files). Please verify
that the current setting of session.save_path is correct (/tmp) in
Unknown on line 0
[end error]
Not sure what I did wrong except to think that PHP is trying to write
the session id file to a directory that doesn't exist /tmp. This is
running on a MS IIS server. If I'm correct in my assessment, where do I
set the default location for session data?
Thanks,
Jeff

Re: [PHP] session_start() || shell access problem......
Thank the heavens above Actually, thank Ben, a poster from php.net manual. Looks like environment variables are not passed to file when it is executed from the command line. A workaround is: $inc_path = $_SERVER['DOCUMENT_ROOT'] . '/'; $remaddr = getenv(DOCUMENT_ROOT); putenv(DOCUMENT_ROOT=$inc_path); That does the trick for what I need done now; namely, being able to include files within my command line executed files.

Re: [PHP] Session_start() corrupt HTML output with IE
Hi hecchan, I don't have a crear idea on what your problem is, but i have read an article on phpfreak.com, it says to work the sessioned PHP scripts correctly with IE6 you have to insert.. header(Cache-control: private); immediatly after starting the session. try this. Viraj p.s. and also if there is any one wo knows what exactly this header line means, please post a brief decription. thanks. hecchan wrote: Hi, Using IE 6 (XP) i can't see the source generated for PHP even the page works properly (It doesn't happend with Mozilla or Opera).

[PHP] session_start() : read failed: Value too large for defined datatype (75) ...
Hello, I'm using an apache server 1.3.28 on RedHat GNU/Linux 6.2 with php 4.3.1. Before, I was using apache 1.3.14 with php 4.0.6. Since I have upgraded, I have problems with session_start. I have tried to set register_globals either to on or to off but it has no effect on this problem. Example : Warning: session_start() [function.session-start]: read failed: Value too large for defined data type (75) in /var/www/htdocs/site/ssl/accueil/connexion.php on line 28 (Before upgrading, it was running without any problem.) How can I solve this problem?

[PHP] session_start questions.
Questions, Questions, Questions. Where do I start in understanding how this function works. Ive read the document multiple times, and I am having a bit of trouble figuring out how this function works. I know that you can take session data and hold it somewhere for a user and use that data throughout php web pages. I am wandering, where is this data held and how to do you reference it ? Is their a more detailed explanantion of session's ? If their is not, once I get this, I will write one for people like me. You know, Sessions for Dummies ;o) Never the less, how do you set a session name for a specific user and hold that data for processing? Is this magic from somewhere or do you specifically name a session for every user ? What about security implications ? I will be running all my forms through secured protocol so hopefully their wont be any hijacking going on... Sorry for being a pain.

[snip] Not to be nosey or anything but usually session data will always be saved or not. How come one would want to check to see if is was or not. [snip] Maybe I am on the wrong track but the other day I got a disk full error when I was sending some mail... at the same time while my website was working, it wasnt saving session data, so users were getting sent back to the login page instead of going on to use the site. What I was hoping to do was to be able to give a error message if the server was having this problem, but in order to do that I was needing a way of knowing if it was because the session_start failed or users who didnt have cookies turned on. I probably just need to get a new host since these disk full errors happen regularly. :( Mr P. -- __ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

According to the PHP manual session_start always returns true.
Ther are times (like when there is a disk full error on the server) that the
sesison_start will fail because its unable to write the session tmp file.
So shouldnt session_start be able to return false if the file write fails?
Or does it return false but the manual doesnt say so?
[snip]
session_start() just prepares for session use:
- check for an existing session ID (cookie or request parameter
- if found, retrieve stored session data
- else generate new session key
- check garbage collection (gc_probability)
There's nothing that it does to prepare to write the session file, this is
done when your script exits.
BTW, having a look at the implementation in ext/session/session.c, the
function is declared returning void:
PHPAPI void php_session_start(TSRMLS_D)
The actual return value being stored in register AX (at least on Intel
platforms) it is most unlikely that ax contains a zero value. The last
statements at function end are:
if (PS(mod_data) PS(gc_probability) 0) {
int nrdels = -1;
nrand = (int) (100.0*php_combined_lcg(TSRMLS_C));
if (nrand PS(gc_probability)) {
PS(mod)-gc(PS(mod_data), PS(gc_maxlifetime), nrdels TSRMLS_CC);
}
}
PS(mod_data): returns a pointer to internal data structures, not zero.
PS(gc_probability): usually 1.
nrand: seldom zero value.
Result: Will return false if (and only if) the garbage collector routine
(gc) returns false.
But anyway this has only academic value since php_session_start() is
declared to return void - this should be stated correctly in the manual IMHO.

Re: [PHP] session_start
So how do I check if the session write failed?
I thought perhaps
if(session_id() == ){
echo error;
}
but if all session_start does is basically assign a session ID then
session_id will never be empty even when the write fails.
Thanks! :)
