Bug Type: Zlib Related
Operating System: Linux (2.4.17)
PHP Version: 4.1.1
New Comment:
For opening zip-files via ftp or httpd, there is a little
note in the manual:
Note: The current CVS version 4.0.4-dev introduces a
fopen-wrapper for .gz-files, so that you can use a special
'zlib:' URL to access compressed files transparently using
the normal f*() file access functions if you prepend the
filename or path with a 'zlib:' prefix when calling
fopen().
This feature requires a C runtime library that provides
the fopencookie() function. To my current knowledge the
GNU libc is the only library that provides this feature.
But for sure, this is not a solution for the errormessage
:-)

It's not clear from the manual whether or not gzopen is
SUPPOSED to work with http:// and ftp:// URL's, but I get
the impression the answer is "not yet". (The
documentation in the manual IMPLIES that it the
filehandle-like functions should work with the exception
of socket functions, but the user commentary below the
gzopen entry implies that it doesn't work for http://
URL's either...)
However, when attempting to gzopen a .gz file from an FTP
site, the error message returned is very strange:
-----------------------------------------------------
<b>Warning</b>:
gzopen("ftp://ftp.ncbi.nih.gov/genbank/gbpln3.seq.gz","r";)
- Success in <b>projects/phpdna/get28s.php</b> on line
<b>69</b><br>
Like, dude! Couldn't gzopen
ftp://ftp.ncbi.nih.gov/genbank/gbpln3.seq.gz!
The gzopen returned
-----------------------------------------------------
("Warning - Success?????")
(the section of code that does this is:
-----------------------------------------------------
if(!($fhandle=gzopen($filename,"r")))
{
print("Like, dude! Couldn't gzopen
$filename!\n");
print("The gzopen returned $fhandle\n");
}
-----------------------------------------------------
where filename has obviously been passed as
ftp://ftp.ncbi.nih.gov/genbank/gbpln3.seq.gz
There's a pause that implies the connection attempt is
being made.
(quick update, I just re-ran the script and did a capture
with 'ethereal' - a connection IS being made and, passive
mode is being switched to, and the RETR is started on the
file, and about 3 1K packets seem to come across. Are FTP
URL's supposed to work? Is this a 'gzopen ftp://' bug
rather than an error message bug?)
I'll report the "Please Oh Please add http/ftp URL support
to gzopen like fopen has!" separately as a feature request
later, presuming it doesn't turn out that it's already
been done and I just don't know what I'm doing... Thanks!
