Question on file upload

Yes I am looking to change the C implementation.

The problem is - the uploaded temp file is already created by httpd server even before it gets to php.

In php I just need to find this temp file, trim the headers and avoid
file copy by php being done by following code in rfc1867.c

while (!cancel_upload && (blen = multipart_buffer_read(mbuff, buff, sizeof(buff), &end TSRMLS_CC)))
{
if (php_rfc1867_callback != NULL) {
multipart_event_file_data event_file_data;
event_file_data.post_bytes_processed = SG(read_post_bytes);
event_file_data.offset = offset;
event_file_data.data = buff;
event_file_data.length = blen;
event_file_data.newlength = &blen;
if (php_rfc1867_callback(MULTIPART_EVENT_FILE_DATA,
&event_file_data, &event_extra_data TSRMLS_CC) == FAILURE) {

...

While following multipart_buffer_read I cannot find the place where it is reading the temp file to fill this buffer.

Thanks

I'm not sure if you're looking to change the C implementation or not,
but you could always bypass the internal processing of the file. Set
post_max_size to 0 and parse the HTTP_RAW_POST_DATA manually.

Hello,

I want to change the way file upload processing is done in php. We
have a http server (appweb)
that puts the uploaded file to a temp directory. This file has
headers at the beginning and end.

I am looking at code rfc1867.c. This code takes the temp file and
seems to extract the real file.
I want to change it so instead of entire file, I can run a system
awk command to trim the
header lines to get the actual file.

Has anyone done something similar? I cant find the place where the
actual file is being read?
Can someone please point to that.

This is php 5.2 on bsd.

Thanks
