Hi, I had a look at this bug [0]. Not being able to completely import a .bz2 file is serious. The .bz2 generated by phpMyAdmin (with $cfg['CompressOnFly'] being true by default) contains extra headers that are not handled correctly by the bzread() function. This happens for export files reaching a certain size. Curiously, the bunzip2 command handles the file correctly. Forcing $cfg['CompressOnFly'] to false for .bz2 will only bring us memory problems at export time. I have contacted the author of bzip, asking for an opinion. No answer so far after four days. I see two possible solutions: - ask users to uncompress / recompress their .bz2 export file before importing (not elegant; might be difficult to make this procedure known to users) - withdraw support for exporting/importing in .bz2 [0] https://sourceforge.net/p/phpmyadmin/bugs/4221/ -- Marc Delisle http://infomarc.info | http://phpmyadmin.net
