[PATCH v2 2/5] lib: qemu: Factor out common code for reading and writing cache files.
The previous code duplicated a lot of common code for reading and
writing the cache file per data field. This change simply factors out
that common code. This makes it simpler to add new tests in future.
This is just refactoring, it should have no effect.

"corrupted size vs. prev_size" when calling ExecutionSession::lookup()
Hi, I wrote a compiler that generate IR code and run it on the JIT, and
there randomly crashed due to "corrupted size vs. prev_size" depends on the
IR code generated from the source code.
Here's how I created the JIT:
llvm::InitializeNativeTarget();
llvm::InitializeNativeTargetAsmPrinter();
llvm::InitializeNativeTargetAsmParser();
// create jit
llvm::orc::ExecutionSession

[PATCH 4/4] lib: qemu: Memoize qemu feature detection.
qemu feature detection takes about 95ms on my laptop. The overhead is
almost all due to the time taken by the glibc link loader opening the
170+ libraries that qemu is linked to (×2 because we need to run qemu
twice).
Fixing that is seriously hard work.
Therefore memoize the results of guestfs_int_test_qemu.
This is keyed on the size and mtime of the qemu binary, so if the user
changes the

Plugin like zlib
Hi everyone.
I rebuild a plugin, based on zlib plugin.
The changes between this plugin and zlib, is the zlib stuffs is replaced by
open, read, lseek, close.
With "plain-text" files, its works ok.
So, my file is encrypt, and the result from decrypt file is different from
fread.
Like zlib, i read from fread the size variable, but the value added in
seek_offset and pos is the result from

Any idea what the problem could be? Is there anything more i could do
to encircle the problem? Or perhaps is the information i provided

Aloha Timo.
I found a few odd things while playing with dovecot. At least
one of them bugs me, but it might be a result of my own
patches - I haven't testet it with mbox or maildir, yet.
The details :)

[PATCH] lib: direct: Query qemu binary for availability of KVM (RHBZ#1605071).
When using the direct backend, you should see the result of testing
the qemu binary for the availability of KVM:

daemon: btrfs: check end_stringsbuf return values everywhere
java: use cleanup handlers for structs (lists) as return values
lib: qemu: improve handling of FILE*
p2v: check more return values
p2v: fix possible close(-1) issue

[PATCH 0/4] lib: qemu: Add test for mandatory locking.
The patch I posted last week to disable mandatory locking for readonly
drives
(https://www.redhat.com/archives/libguestfs/2017-September/msg00013.html)
was wrong in a couple of respects. Firstly it didn't work, which I
didn't detect because my tests were testing the wrong thing. Oops.
Secondly it used a simple version number check to detect qemu binaries
implementing mandatory locking.

[PATCH v3 0/6] launch: direct: Disable qemu locking when opening drives readonly.
v2 -> v3:
- I addressed everything that Pino mentioned last time.
- It's tricky to get a stable run when multiple copies of qemu are
involved, because the same cache files get overwritten by parallel
libguestfs. So I changed the names of the cache files to include
the qemu binary key (size, mtime), which removes this conflict.
This is in new patch 4/6.
Rich.

[PATCH v2 0/5] launch: direct: Disable qemu locking when opening drives readonly (RHBZ#1417306)
Patches 1-4 are almost the same as they are when previously posted
here:
https://www.redhat.com/archives/libguestfs/2017-September/msg00039.html
Patch 5 actually uses the mandatory locking test to turn off locking
in the narrow case where a drive is opened readonly, and then only for
the drive being inspected.
Passes ordinary tests (‘check-direct’ and ‘check-valgrind-direct’).
Rich.

Compressed maildir
Greetings,
I noticed a while back someone posted a patch/plugin that allowed Dovecot to
use compressed mbox files. I'm now wondering how far that would put us from
having compressed maildir? I have a server with more CPU than disk space, and
while I can buy more HDD space, my backup solution doesn't make that practical.
It seems to me that when looking for a message file, if it

[PATCH 0/4] qemu: Use sqlite to store qemu detection data.
Patches 1 & 2 were posted previously here:
https://www.redhat.com/archives/libguestfs/2016-May/msg00134.html
Patch 3 is a hack so I can test this using my own version of qemu (the
`-L ?' stuff is not upstream).
Patch 4 is where the real action takes place: Replace the caching of
qemu features in blob-like files with a sqlite database. Probably the
best way to approach this patch is to

[PATCH 0/2] Use -bios bios-fast.bin where supported.
NOTE: Not for upstream, yet.
This depends on 3 non-upstream patches.
- The qemu rework in libguestfs, which in turn depends on what
Pino is up to.
- Support for '-L ?' in qemu:

[PATCH v2 0/2] Use -bios bios-fast.bin where supported.
This commit uses -bios bios-fast.bin if available, which basically
stops SeaBIOS from trying to do PCI probing during boot, which is a
waste of time when using the -kernel option.
v1 -> v2:
- Rebase on top of Pino's work.
This still has 3 dependencies:
- The qemu memoization work (v2).
- Support for '-L ?' in qemu:
