[PHP] How to make sure that the target file to read is not under writing by others?
Hi everyone: I have a crontab command to execuate my php-script every half an hour. The mission of the php-script is to open a file(log file), examine it. The target file(log file) is transported to local every half an hour. I've no idea how much time it will costs and on the other hand, i want to make sure the file i'm openning is Completely Written. Any instruction will be grateful. PS: I've made a test. My php-script just "fopen" a local file being transported in, and the "fopen" returns no FALSE value but a resource. Dengxule 2009/08/19
[PHP] Lots of fstat() calls in PHP 5.3
Hi,
We recently upgraded our web servers with PHP 5.3 and found out that
there are lots of fstat() calls. fstat() is called 3 times on each file
open. Do you know why this happens and how can these calls be reduced?
We're running Red Hat 3.4.6, Apache 2.0.59, PHP 5.3.0 with APC.
Here's strace example (I replaced full paths by [PATH]):
open("[PATH]/RecommendationsManager.php", O_RDONLY) = 19
fstat(19, {st_mode=S_IFREG|0777, st_size=16937, ...}) = 0
fstat(19, {st_mode=S_IFREG|0777, st_size=16937, ...}) = 0
fstat(19, {st_mode=S_IFREG|0777, st_size=16937, ...}) = 0
mmap(NULL, 16937, PROT_READ, MAP_SHARED, 19, 0) = 0x2a9f441000
stat[PATH]RecommendationsManager.php", {st_mode=S_IFREG|0777,
st_size=16937, ...}) = 0
munmap(0x2a9f441000, 16937) = 0
close(19) = 0
open[PATH]/Recommendations.php", O_RDONLY) = 19
fstat(19, {st_mode=S_IFREG|0777, st_size=10695, ...}) = 0
fstat(19, {st_mode=S_IFREG|0777, st_size=10695, ...}) = 0
fstat(19, {st_mode=S_IFREG|0777, st_size=10695, ...}) = 0
mmap(NULL, 10695, PROT_READ, MAP_SHARED, 19, 0) = 0x2a9f441000
stat([PATH]/Recommendations.php", {st_mode=S_IFREG|0777, st_size=10695,
...}) = 0
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0x2a9f444000
munmap(0x2a9f441000, 10695) = 0

First thing to do is figure out how large the log you expect to parse is going to be, and from there, have a guess at how long it will take to transfer fully from elsewhere. I'd make the cron script a bit more frequent, but only ask it to look for files that have changed between x and y minutes ago, where y is a minute or two over the transfer duration. Then you can either mark the file in some way, or move it to another location to indicate it has been processed.

Thanks, Ash http://www.ashleysheridan.co.uk -- You can open the control file any time you want. The info in the control file tells you whether to proceed. The transfer program adds the entry when the log has been transferred, the processing script updates the entry to indicate it's been processed. You can either add a new entry each time (useful for monitoring to fine-tune the timing, or for keeping a history) or work on a single entry that's overwritten each time the log is transferred.

WARNING: total newbie here. If I understood Arno correctly, he was recommending to implement something like the old "/var/run/*pid" files in UNIX. That way, you can control whether or not the previous run is already done with the file before you move on. That is definitely the correct approach. Have the script which copies the log file touch a file called 'log_file.write' or some such. When it's done, remove the file. Your PHP script should exit if that file exists. Of course, given the 30 minute cron cycle, it would then have to wait until the next cycle. Maybe run it more often.

What would happen if you tried to access the control log file whilst it was in the process of being written to? Admittedly, you reduce your chances of failure because there is less data being written to the control log than the actual log, but the chance of reading incomplete data is still there! Thanks, Ash http://www.ashleysheridan.co.uk A control file is used to control processing, a log file is used to log events. I'm definitely talking about a control file. If the control file happens to keep a log then it's a bonus, but not its primary purpose. Access the control file while being written to? I'm talking about a short single-line entry, and the file is only written to when the write command is processed. Copying a file is very different to issuing a single write command. Don't forget that PHP and webservers run on top of operating systems, and the OS ultimately handles all file activity. The OS ensures that another process can't read a file that is halfway through a write command (any computer would instantly crash if that sort of basic housekeeping wasn't done). If you don't trust the OS then file locking can be used (though pointless in this case). For the ultra-paranoids who don't trust OS's or locks you can either (a) choose a different career, or (b) add a time-stamp to the beginning of the entry and check that the entry wasn't written in the last few nanoseconds (if you get this far I'd recommend option a). You can even go so far as to check the length of the timestamp string to be sure that you got all of it, and if it's too short you know you're busy reading a file that's halfway through a write command, and sleep for a millisecond and then try again ;) Cheers Arno -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

To quote the PHP manual: "If handle was fopen()ed in append mode, fwrite()s are atomic (unless the size of string exceeds the filesystem's block size, on some platforms, and as long as the file is on a local filesystem). That is, there is no need to flock() a resource before calling fwrite(); all of the data will be written without interruption."

Guess you didn't like this one? Also, if you change the / to - in the
preg_replace() it should work on Euro style dates.
$date = preg_replace("#([\d])+[^-\d]+([\d]+)[^-\d]+([\d]+)#",

[PHP] SESSIONS lost sometimes
Dear all, We have a server with a site that does some XML calls. After lots of testing I have found that the server is losing session variables. However sometimes it isn't losing them so I don't think it's a code thing rather a server issue. The strange thing is that its not consistent. Things to note: The session array is really big, quite a few variables. Also the site goes from HTTP to HTTPS at some point but this isn't the issue as it loses the sessions as soon as they are set sometimes. Therefore I would like to know what I could check. I have read in other posts that I should check: -Disk space -Garbage collection running too frequently and reducing session lifetime in an ini_set and it might be possible that my live sessions are being erronously treated as garbage. -Is there any other settings that I can check or should the above be all I should check Please any advise, comments, help is appreciated.

[PHP] mssql_bind Question
Code in question: mssql_bind($stmt, '@managerName',$managerName,SQLVARCHAR,false,false,50); For a normal varchar field, the length is obvious, in this case 50. But for an ntext field, how do I use the mssql_bind statement? Far as I know, these are the only available "types" to use: SQLTEXT, SQLVARCHAR, SQLCHAR, SQLINT1, SQLINT2, SQLINT4, SQLBIT, SQLFLT4, SQLFLT8, SQLFLTN I need to use which type, and what length to use...?

Perl was much harder It would probably bomb your performance but you could always call a separate PHP script from your Perl code: #!/usr/bin/perl # do some stuff in perl my $php_output = `/usr/bin/php whatever.php` # do something with $php_output 1; If you're just looking to add some features quickly to your existing Perl code: Have you searched CPAN for what you need?

It would be easier if you kept a record of the status changes to and from busy (check-in and check-out) as a transaction log. Then you can scan the log to see the status changes for any time period. But you still have to deal with a room that stayed busy for the entire period. First question, does busy include the time needed by housekeeping to clean the room after checkout? You might want to consider a separate status for that. Second question, does the system keep track of when each room is reserved? If one is reserved for three nights beginning Friday, can it still be used Wednesday for a one or two night stay?

I have read in other Can you clarify what you mean by "losing sessions"? Have you taken a network trace to see whether the client is consistently sending the session ID with every request? When the problem happens, is $_SESSION completely empty or is it only missing some variables? Does it seem to happen on any page, or only certain ones?

[PHP] Extract column names from a (my)SQL query
Lets assume I have the following string: "SELECT field1, field2, field3 FROM tablename WHERE field1 = 'something' " Is there any way to get "field1, field2, field3"? assuming it might also have join, left join - things like that. I can easily do it with preg_match, but I have to make sure its "foolproof". It would be a lot better if it will also be able to parse the whole query - catch limit, where, joins, comments Is there any php class that could do it? I've looked in the pear site and on Google but haven't had any luck. -- Use ROT26 for best security

You can't do euro type dates or any other format because there is no
way to tell the difference between 1/2/2009 (January) and 1/2/2009
(February):
Guess you didn't like this one? Also, if you change the / to - in the
preg_replace() it should work on Euro style dates.
$date = preg_replace("#([\d])+[^-\d]+([\d]+)[^-\d]+([\d]+)#",
"$1-$2-$3", $date);

Thanks, but my idea was more along the lines of this:
http://php1.net/b/date-picker/index.php
It's not thoroughly tested, but thus far it works.

I gather from this discussion that PHP allows two users to open a file for R/W?
I had
assumed it wouldn't.
Anyway, how about:
$user = 'Fred'; $try_again = true;
If (!file_exists('Busy.txt'))
{
File_put_contents ('Busy.txt', $user);
If ($user == File_get_contents ('Busy.txt')
{
// Do what you have to
Unlink ('Busy.txt');
$try_again = false;
}
}
if ($try_again)
{
// Come back in 5 minutes
}
This has a theoretical weakness, in that Joe could check for Busy.txt in the
interval
between your checking and writing it, and then write his copy after you had
read your
copy. A moments delay between writing and re-reading would fix this.

I haven't really gone over it with a fine-toothed comb though. Typos etc. are still up to to you. :) Of course, the whole thing depends on how tms_daemon behaves, but the startup script looks OK. Can you explain in a bit more detail exactly what the second part (the serial-network data logger) needs to do? I've written similar daemons in C but not PHP--when I've needed to get something like that going with a PHP script, I've used ser2net (which I linked to in an earlier post) and been quite happy.
