cvs update -f "Jan 22 02:07:44 2007 UTC"

I committed a workaround for the failure, completely 
forgetting you needed the file for this bug, sorry.  This 
is the patch that needs to be reversed:

I have to say, I can't reproduce it on my Suse either.
4 tests fail, but the ones you mentioned work fine.

Btw, phar_oo_compressed_001.phpt fails because of several leaks:

016+ /local/dev/php/5_2/main/streams/streams.c(386) : Stream of type
'MEMORY' 0x40203094 (path:(null)) was not closed
017+ /local/dev/php/5_2/main/streams/streams.c(386) : Stream of type
'TEMP' 0x402004f8 (path:(null)) was not closed

You need to close those streams when destroying the object.

Seems to work fine here... (incidentally same OS and PHP version):

Sara, could you look into this?
Btw, I can see the very same code in ext/bz2.

Description:
------------
run the test pecl/phar/tests/phar_ctx_001.phpt or
pecl/phar/tests/phar_oo_compressed_001.phpt

and you will see an endless loop.  The loop happens in
ext/zlib/zlib_filter.c at line 83:

                while (bin < bucket->buflen) {
                        desired = bucket->buflen - bin;
                        if (desired > data->inbuf_len) {
                                desired = data->inbuf_len;
                        }
                        memcpy(data->strm.next_in, bucket->buf + bin, desired);
                        data->strm.avail_in = desired;

                        status = inflate(&(data->strm), flags & 
PSFS_FLAG_FLUSH_CLOSE ?
Z_FINISH : Z_SYNC_FLUSH);
                        if (status != Z_OK && status != Z_STREAM_END) {
                                /* Something bad happened */
                                php_stream_bucket_delref(bucket TSRMLS_CC);
                                return PSFS_ERR_FATAL;
                        }
                        desired -= data->strm.avail_in; /* desired becomes what 
we consumed
this round through */
                        data->strm.next_in = data->inbuf;
                        data->strm.avail_in = 0;
                        consumed += desired;
                        bin += desired;

                        if (data->strm.avail_out < data->outbuf_len) {
                                php_stream_bucket *out_bucket;
                                size_t bucketlen = data->outbuf_len - 
data->strm.avail_out;
                                out_bucket = php_stream_bucket_new(stream, 
estrndup(data->outbuf,
bucketlen), bucketlen, 1, 0 TSRMLS_CC);
                                php_stream_bucket_append(buckets_out, 
out_bucket TSRMLS_CC);
                                data->strm.avail_out = data->outbuf_len;
                                data->strm.next_out = data->outbuf;
                                exit_status = PSFS_PASS_ON;
                        }
                }

the loop should exit when desired is set to 0, but doesn't.

The attached patch fixes this issue.
