2019-03-08qemu-iotests: Improve portability by searching bash in the $PATHPhilippe Mathieu-Daudé
Bash is not always installed as /bin/bash. In particular on OpenBSD, the package installs it in /usr/local/bin. Use the 'env' shebang to search bash in the $PATH. Patch created mechanically by running: $ git grep -lE '#! ?/bin/bash' -- tests/qemu-iotests \ | while read f; do \ sed -i 's|^#!.\?/bin/bash$|#!/usr/bin/env bash|' $f; \ done Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2018-11-19iotests: Drop use of bash keyword 'function'Eric Blake
Bash allows functions to be declared with or without the leading keyword 'function'; but including the keyword does not comply with POSIX syntax, and is confusing to ksh users where the use of the keyword changes the scoping rules for functions. Stick to the POSIX form through iotests. Done mechanically with: sed -i 's/^function //' $(git ls-files tests/qemu-iotests) Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <20181116215002.2124581-1-eblake@redhat.com> Reviewed-by: Daniel P.

2018-11-19qemu-iotests: remove unused variable 'here'Mao Zhongyi
Running git grep '\$here' tests/qemu-iotests has 0 hits, which means we are setting a variable that has no use. It appears that commit e8f8624d removed the last use. So execute the following cmd to remove all of the 'here=...' lines as dead code. sed -i '/^here=/d' $(git grep -l '^here=' tests/qemu-iotests) Cc: kwolf@redhat.com Cc: mreitz@redhat.com Cc: eblake@redhat.com Suggested-by: Eric Blake <eblake@redhat.com> Signed-off-by: Mao Zhongyi <maozhongyi@cmss.chinamobile.com> Message-Id: <20181024094051.4470-3-maozhongyi@cmss.chinamobile.com> Reviewed-by: Eric Blake <eblake@redhat.com> [eblake: touch up commit message, reorder series, rebase to master] Signed-off-by: Eric Blake <eblake@redhat.com>
2016-04-15qemu-iotests: tests: do not set unused tmp variableSascha Silbe
The previous commit removed the last usage of ${tmp} inside the tests themselves; the only remaining users are sourced by check. So we can now drop this variable from the tests.

Filter out the "main loop: WARNING: I/O thread spun for..." warning from qemu output (it hardly matters for code specifically testing I/O). Furthermore, use _filter_qemu in all the custom functions which run qemu. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

VMDK extent parsing code doesn't handle the JSON file name, so the case fails for these subformats. Disabled them.

2014-09-22block: delete cow block driverStefan Hajnoczi
This patch removes support for the cow file format. Normally we do not break backwards compatibility but in this case there is no impact and it is the most logical option. Extraordinary claims require extraordinary evidence so I will show why removing the cow block driver is the right thing to do. The cow file format is the disk image format for Usermode Linux, a way of running a Linux system in userspace. The performance of UML was never great and it was hacky, but it enjoyed some popularity before hardware virtualization support became mainstream. QEMU's block/cow.c is supposed to read this image file format. Unfortunately the file format was underspecified: 1. Earlier Linux versions used the MAXPATHLEN constant for the backing filename field. The value of MAXPATHLEN can change, so Linux switched to a 4096 literal but QEMU has a 1024 literal. 2. Padding was not used on the header struct (both in the Linux kernel and in QEMU) so the struct layout varied across architectures. In particular, i386 and x86_64 were different due to int64_t alignment differences. Linux now uses __attribute__((packed)), QEMU does not. Therefore: 1. QEMU cow images do not conform to the Linux cow image file format. 2. cow images cannot be shared between different host architectures. This means QEMU cow images are useless and QEMU has not had bug reports from users actually hitting these issues. Let's get rid of this thing, it serves no purpose and no one will be affected.
