similar to: [PATCH nbdkit] tests: xz: Use 16M block size when preparing disk for xz plugin test.

In a recent commit guestfish changed the default size for disk images prepared using the -N parameter from 100M to 1G: https://github.com/libguestfs/libguestfs/commit/adc23829e4b128562c2c29d984654528bd259644 For the xz plugin test we prepared a disk image using guestfish and then xz-compressing the output, but we did not take our own advice and use the --block-size parameter to limit the xz

v2: - Fixes a number of bugs in corner cases. - Uses a 1M block size to fetch from the underlying plugin. This improves performance considerably. I also tested this much more thoroughly and can't find any more bugs. Rich.

Matt asked if xz should really be a filter rather than a plugin. The answer is yes, of course it should be! That's been something in the todo file for a while. The commit converts the xz plugin code into a filter (leaving the plugin around, but deprecating it). plugin: nbdkit xz file.xz filter: nbdkit --filter=xz file file.xz plugin: # can't be done filter: nbdkit

CentOS 6 has libguestfs-devel 1.20.11, which predates the support in guestfs_add_drive_opts() for requesting an nbd drive instead of a local file (annoyingly, guestfs documentation merely states the function was available since 0.3, without saying which later releases added new options); causing a compilation failure during 'make check'. Maybe the guestfs plugin should still be built,

There is a small test provided. I tested this a lot more locally and it seems pretty robust. Rich.

I've posted some of these patches or ideas before; but now I'm confident enough with the series that it should be ready to push; at any rate, I can now run test-socket-activation in a tight loop without triggering any crashes or hangs. With this in place, I'm going back to work on making the nbd forwarder wort with the parallel thread model. Eric Blake (8): sockets: Use

A bit of refactoring to the HAVE_LIBGUESTFS conditional, coupled with the addition of a LIBGUESTFS_TESTS intermediate list, allows us to run a few more tests on CentOS 6 (adding some tests of command-line behavior and filters that was previously completely skipped). For the two tests that we can't run, using check_PROGRAMS still causes those programs to try to compile (which leads to compile

In libguestfs we have a few tests that require root privileges and they are skipped by default (normally you should not build or test as root), but you can do this to run them: sudo make check-root In nbdkit I wanted to check that the file plugin works with block devices (this is not tested), and the only way I can sensibly think to do this is using a loopback device and root. This commit

This filter caches the last result of the extents() call and offers a nice speed-up for clients that only support req_on=1 in combination with plugins like vddk, which has no overhead for returning information for multiple extents in one call, but that call is very time-consuming. Quick test showed that on a fast connection and a sparsely allocated 16G disk with a OS installed `qemu-img map` runs

Make sure the fake disk exist, otherwise nbdkit fails. Also, give the fake disk a less generic file name. --- tests/test-single.sh | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/tests/test-single.sh b/tests/test-single.sh index d60538d..9dc462b 100755 --- a/tests/test-single.sh +++ b/tests/test-single.sh @@ -45,11 +45,13 @@ if ! qemu-img --help >/dev/null; then

To avoid bitrot, any new feature needs testsuite coverage ;) Still to come: once I get my work on parallel nbd finished, I will add a test-parallel-nbd.sh that closely mirrors what my other series added in test-parallel-file.sh. If desired, it might be a fun exercise to tweak test-nbd into using a for-loop of user-controlled depth for how deep you want to nest the forwarding tree, to see where

Is there a mechanism by which you can perform a zfs send | zfs receive and not have the data uncompressed and recompressed at the other end? I have a gzip-9 compressed filesystem that I want to backup to a remote system and would prefer not to have to recompress everything again at such great computation expense. If this doesn''t exist, how would one go about creating an RFE for

yes I know I can do that, but my question is if there is software to edit FLAC files without having to uncompress to WAV/recompress to FLAC. 2007/7/23, Avuton Olrich <avuton@gmail.com>: > > On 7/23/07, Harry Sack <tranzedude@gmail.com> wrote: > > hi > > > > does somebody know software for editing FLAC files?

This is a revised version of the two series previously posted here: https://www.redhat.com/archives/libguestfs/2019-January/msg00137.html https://www.redhat.com/archives/libguestfs/2019-January/msg00139.html There have been many smaller changes but the highlights are: - Using SECTOR_SIZE instead of hard-coding 512 everywhere. - Additional safety checks that the EBR chain doesn't jump

Joseph, Please try my modified versions of these patches. These are compile-tested on Fedora and they don't break any existing functionality, but I don't have either urpmi nor a statically-linked xz so I cannot fully test them. I have also fixed detection of zlib (2/3). Rich.

v1 was here: https://www.redhat.com/archives/libguestfs/2019-September/msg00100.html In v2 I've changed the patch so it avoids calling realloc at all in this case. The patch is a bit longer this way. But I don't see any other alternative if we are to avoid having a "realloc wrapper" of some kind that we use everywhere, which I guess we should avoid because it makes plugins

I just setup a new SSD with my laptop root filesystem, and at the time I though, "eh, I''ll just use zlib compression during the first copy, and then switch to lzo afterwards to maintain write speed when I''m using the laptop after the copy and reboot". Now, I rebooted with the new ssd and zlib compressed rootfs, and it seemed to boot slower than it did before with the

hi does somebody know software for editing FLAC files? So I just want to cut some pieces out of the file (for example silence in front of a recording) thx -------------- next part -------------- An HTML attachment was scrubbed...
