I was afraid it was a bug. I have generally just used whatever is at whatever host, until this project, and didn't really think something so glaring could be in there. WTF! I wonder if massive uploads, like the ones you're coding for, really aren't that common. I can imagine hard-coding that 3600 myself, and thinking, no way someone's going to be uploading a single file for longer than an hour, or even close to it. So, it seems like it would be pretty straight forward to fix this, if I was willing to run on a custom version until this fix is released. Do people do that? What do you think? After looking at it bit more, I found another PECL bug, same basic underlying problem, that was fixed almost a year ago: http://pecl.php.net/bugs/bug.php?id=14198 That's when the config option apc.rfc1867_ttl was introduced to APC -- but some of that hardcoded 3600 remained until a few weeks ago. The older bug (14198) sounds exactly like your problem, so if I were you I'd start by trying any of the official versions that include the fix for 14198. That fix was committed on August 29 of 2008: http://svn.php.net/viewvc?view=revisionrevision=265595 So the next version up (3.1.1) from what you're currently using will include it. I guess 3.1.1 is still in beta but I'd personally go for beta over a custom build, at least on a first pass.

With a desktop application you can send credentials and the SHA1 of the file in order to create it's ghost image on the server.

To allow a resume you simply need to communicate the current big file size / 2 Mb and you know which chunk needs to be uploaded.

In a biz environment, connections are pretty stable, and usually fairly fast. This gives them a familiar interface to upload. Anyway, this was the spec I was given. Adding interruption recovery is a nice phase 2, upgrade. I am just happy it is working now. The APC upload progress thing works great (above mentioned limitations aside).

then I did - when I tried uploading some different files. It seems
that larger files always give a negative response for me. Now I am
thinking that it has been a timing issue. My ajax stuff doesn't repeat
yet, so there is currently only one request. It seems that if the file
is a little too large, the first response is always false, that may be
the case for very small files too. I finally just picked a file that

me to go ahead and iron out the ajax stuff.
Anyway now I can move forward.
Thanks all for all your suggestions, sorry this ends up being such a
stupid conclusion.

I have in my php.ini:
apc.rfc1867 = On

The apc.php diagnostic/report page says it is on. It just returns
false. I
will look at your zip file and see if something jumps out.
what about your other apc.rfc1867 settings?
are you posting the correct field to the server to tell apc to start
tracking, and also are you grabbing the correct value when trying to
determine the status in your progress tracking script?
by default, your form needs an input like,
input type=hidden name=APC_UPLOAD_PROGRESS
id=progress_key value=?php echo $id?/
then in the progress checking script you will need something like,
?php
if(isset($_GET['progress_key'])) {
$status = apc_fetch('upload_'.$_GET['progress_key']);
echo $status['current']/$status['total']*100;
}
?
the names of these variables depend upon apc.rfc1867_name
and apc.rfc1867_prefix respectively. take a look at this article,
it was
really helpful,
http://www.ibm.com/developerworks/opensource/library/os-php-v525/
also, to get going fast, dont bother w/ the progress script yet.
just focus
on getting apc to start tracking the progress. you can use the stock
apc.php script from the distro and upload a large file; this will
give you
time to check in apc.php.

I looked at your link, and it looks great, perhaps you have some insight into my narrow APC problem. One other thing, Eddie was talking about APC not being thread-safe. I have heard this before, but also heard it refuted. Do you have any insight on this? I am going insane, so any help you can toss my way would be most merciful.

RE: [PHP] APC - Upload progress problem. apc
The concept of my last link is this: the instant before you do the upload you ask PHP to scan the tmp folder, or the folder used to upload files (often the tmp) and you snap number of files, then the upload starts, and it will create a temp file with a PHP predefined prefix, you array_diff the snap with the current file list and you get the file that the user is uploading. At that point if you are lucky the input=file field will give you access to its fileSize, and you have everything to create a progress bar: the polled incremental tmp file size in the server, plus the total in the client, a bit of transitions/effects and that's it. This method is not ideal, generally speaking, because it could easily suffer concurrency between multiple users.

The apc.php diagnostic/report page says it is on. It just returns false. I
will look at your zip file and see if something jumps out.
what about your other apc.rfc1867 settings?
are you posting the correct field to the server to tell apc to start
tracking, and also are you grabbing the correct value when trying to
determine the status in your progress tracking script?
by default, your form needs an input like,
input type=hidden name=APC_UPLOAD_PROGRESS
id=progress_key value=?php echo $id?/
then in the progress checking script you will need something like,
?php
if(isset($_GET['progress_key'])) {
$status = apc_fetch('upload_'.$_GET['progress_key']);
echo $status['current']/$status['total']*100;
}
?
the names of these variables depend upon apc.rfc1867_name
and apc.rfc1867_prefix respectively. take a look at this article, it was
really helpful,
http://www.ibm.com/developerworks/opensource/library/os-php-v525/
also, to get going fast, dont bother w/ the progress script yet. just focus
on getting apc to start tracking the progress. you can use the stock
apc.php script from the distro and upload a large file; this will give you
time to check in apc.php.

I have an existing form that provides other data that need to be linked to the file upload. It looks like swfupload, just uploads all by its lonesome.
