Possible dupe of bug 1073906 (I did not check in detail yet). If it's a dupe then it would be fixed in 1.24.7 and 1.26+. Also my comment here is relevant: https://bugzilla.redhat.com/show_bug.cgi?id=1194472#c2 I checked and this is not reproducible with libguestfs 1.31.1. There was a problem with Java methods (such as g.part_list) which used the RStructList method of returning lists of structures. It didn't affect the other calls you mention because they use a different return method in the generator. This is fixed in 1.24.7 and all recent versions of libguestfs. *** This bug has been marked as a duplicate of bug 1073906 *** |
Description of problem: When trying to list the partitions with g.part_list() an unexpected error is thrown from the undelying native method. Other (deprecated or less useful) functions to show the partitions do work. Version-Release number of selected component (if applicable): libquestfs-1.24.5 (as distributed via Ubuntu 14.04) How reproducible: Steps to Reproduce: 1. use the following code snippet: g.launch(); System.out.println(""); System.out.println("g.part_list does not work"); try { Partition[] partitions = g.part_list("/dev/sda"); } catch (Exception ex) { System.err.println(ex); ex.printStackTrace(); } System.out.println(""); String sfdisk = g.sfdisk_l("/dev/sda"); System.out.println("g.sfdisk_l works"); System.out.println("g.sfdisk_l(\"/dev/sda\"): \n" + sfdisk); System.out.println(""); System.out.println("g.listpartitions also works"); String[] partitions = g.list_partitions(); System.out.println(""); System.out.println("partitions: "); for (String partition : partitions) { System.out.println("partition: " + partition); } System.out.println(""); g.close(); 2. Compile 3. Execute Actual results: g.part_list does not work java.lang.ArrayStoreException java.lang.ArrayStoreException at com.redhat.et.libguestfs.GuestFS._part_list(Native Method) at com.redhat.et.libguestfs.GuestFS.part_list(GuestFS.java:11131) at ListPartitions.main(ListPartitions.java:37) g.sfdisk_l works g.sfdisk_l("/dev/sda"): Disk /dev/sda: 1019 cylinders, 162 heads, 62 sectors/track Units = cylinders of 5142528 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/sda1 * 0+ 49- 50- 248832 83 Linux /dev/sda2 49+ 1019- 970- 4868097 5 Extended /dev/sda3 0 - 0 0 0 Empty /dev/sda4 0 - 0 0 0 Empty /dev/sda5 49+ 1019- 970- 4868096 8e Linux LVM g.listpartitions also works partitions: partition: /dev/sda1 partition: /dev/sda2 partition: /dev/sda5 Expected results: Additional info:
