Vladimir Sementsov-Ogievskiy 9dd003a998 iotests: define group in each iotest
We are going to drop group file. Define group in tests as a preparatory
step.

The patch is generated by

    cd tests/qemu-iotests

    grep '^[0-9]\{3\} ' group | while read line; do
        file=$(awk '{print $1}' <<< "$line");
        groups=$(sed -e 's/^... //' <<< "$line");
        awk "NR==2{print \"# group: $groups\"}1" $file > tmp;
        cat tmp > $file;
    done

Philippe Mathieu-Daudé 11a82d1429 qemu-iotests: Improve portability by searching bash in the $PATH
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

Eric Blake 8cedcffdc1 iotests: Drop use of bash keyword 'function'
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)

Mao Zhongyi bf22957309 qemu-iotests: remove unused variable 'here'
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)

Fam Zheng d04c155503 iotests: 077: Filter out 'resume' lines
In the "Overlapping multiple requests" cases, the 3rd reqs (the break
point B) doesn't wait for the 2nd, and once resumed the I/O will just
continue.  This is because the 2nd is already waiting for the 1st, and
in wait_serialising_requests() there is:

    /* If the request is already (indirectly) waiting for us, or
     * will wait for us as soon as it wakes up, then just go on
     * (instead of producing a deadlock in the former case). */
    if (!req->waiting_for) {
        /* actually break */
        ...
    }

Consequently, the following "sleep 100; resume A" command races with the
completion of that request, and sometimes results in an unexpected
order of output:

> @@ -56,9 +56,9 @@
>  wrote XXX/XXX bytes at offset XXX
>  XXX bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec)
>  blkdebug: Resuming request 'B'
> +blkdebug: Resuming request 'A'
>  wrote XXX/XXX bytes at offset XXX
>  XXX bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec)

>  wrote XXX/XXX bytes at offset XXX
>  XXX bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec)
>  wrote XXX/XXX bytes at offset XXX

Filter out the "Resuming request" lines to make the output
deterministic.

Peter Lieven 117bc3fa22 block/io: optimize bdrv_co_pwritev for small requests
in a read-modify-write cycle a small request might cause
head and tail to fall into the same aligned block. Currently
QEMU reads the same block twice in this case which is
not necessary.

Sascha Silbe 339f06a3bc qemu-iotests: tests: do not set unused tmp variable

themselves; the only remaining users are sourced by check. So we can now

Eric Blake 5be5b7764f blkdebug: Avoid '.' in enum values
Our qapi conventions document that '.' should only be used in
the prefix of downstream names.  BlkdebugEvent was a lone
exception to this.  Changing this is not backwards compatible
to the 'blockdev-add' QMP command; however, that command is
not yet fully stable.  It can also be argued that the testsuite
is the biggest user of blkdebug, and that any other user can
be taught to deal with the change by paying attention to
introspection results.

Done with:

$ for str in \
     l1_grow.{alloc,write,activate}_table \
     l2_alloc.{cow_read,write} \
     refblock_alloc.{hookup,write,write_blocks,write_table,switch_table} \
     pwritev_rmw.{head,after_head,tail,after_tail}; do
   str1=$(echo "$str" | sed 's/\./\\./')
   str2=$(echo "$str" | sed 's/\./_/')
   git grep -l "$str1" | xargs -r sed -i "s/$str1/$str2/g"
 done

followed by a manual touchup to test 77 to keep the test working.

Kevin Wolf 8f9e835fd2 qemu-iotests: Use qemu-io -f $IMGFMT
This patch changes $QEMU_IO so that all tests by default pass a format
argument to qemu-io.

There are a few cases where -f $IMGFMT is not wanted because it selects
the wrong driver or json: filenames including a driver are used. They
are changed to use $QEMU_IO_PROG, which doesn't include any options.

Tests 071 and 081 have output changes because now the actual request
fails instead of reading the 2k probing buffer.

Kevin Wolf f51062061e qemu-iotest: Make 077 raw-only
The qemu-io command sequences make the assumption that an unaligned
request on the format layer will be unaligned on the blkdebug layer as
well. This doesn't necessarily hold true for drivers other than raw.
