#689 (2.3.2) Compressed export returns empty file

[Real Carbonneau]

PHP 4.2.2
phpMyAdmin 2.3.2
MySQL 3.23.52
gzip 1.3.3

The compressed export ("zipped" "gzipped" "bzipped")
returns an empty file when there are many tables
selected (500+). The file is not readable by
compression application such as gzip.

The non-compressed export seems to work correctly
even with a high number of tables.

The compressed export works correctly when a low
number of tables are selected (20-30).

Thanks in advance,
Real

Can't reproduce this....

Maybe the problem is in some php limits you have set, look
into php.ini for these settings.

I have:
max_execution_time = 30
memory_limit = 8M

I confirm that the problem was with the memory_limit
setting. I was configured at 8M also, but it seems that the
script requires about double the memory as the exported
files, it does not seem to be related to the number of files. I
then tried 32M and still had the problem, it worked with 64M.
The .sql file size was 24M before compression.

The error is not reported to the user, but some times the zip
file can be opened with a text viewer and the following error
will be seen: "<br />
<b>Fatal error</b>: Allowed memory size of 33554432
bytes exhausted (tried to allocate 11228193 bytes) in
<b>/var/www/html/myadmin/libraries/zip.lib.php</b> on line
<b>111</b><br />". Other times it returns a "Cannot find
server or DNS Error Internet Explorer" in IE6.

Could you please try current cvs version? It should display
this error instead of posting it as file.
