similar to: [PATCH 00/11] Various Coverity fixes

Hi, some of the bindings may try to malloc with 0 bytes as size when closing an handle, because there were no event handlers registered. Since this can have different behaviours in POSIX, avoid that situation altogether by just skipping allocating anything when there were no event handlers. Thanks, Pino Toscano (4): ocaml: do not try to malloc 0 elements in get_all_event_callbacks python:

The safe_malloc (etc) functions call g->abort_fn on failure. That's not appropriate for language bindings, and we never intended that these internal functions be used from language bindings, that was just a historical accident. This patch series removes any external use of the safe_* functions. Rich.

Make use of functions and types that fit more, and that do the same job: - use PyErr_NoMemory() on malloc failure - use PyErr_SetFromErrno when setting an exception from an errno - throw TypeError if not getting a list when required --- python/handle.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/python/handle.c b/python/handle.c index 88024e1..9746dca 100644 ---

In case there are no event handlers registered with the handle, get_all_event_callbacks will count 0 elements, trying to malloc a buffer of that size. POSIX says that this can result in either a null pointer, or an unusable pointer. Since we assume a null pointer means failure, then always add a null element at the end, so we do not rely on implementation-defined behaviour of malloc. The output

Extend the internal libguestfsmod module with the CREATE values, so there is no need to hardcode values in GuestFS.__init__. --- generator/python.ml | 7 +++++-- python/guestfs-py-byhand.c | 7 +++++++ python/guestfs-py.h | 2 ++ 3 files changed, 14 insertions(+), 2 deletions(-) diff --git a/generator/python.ml b/generator/python.ml index 9744b8f..470abe7 100644 ---

Hi, this patch series fixes few more issues discovered by Coverity. Thanks, Pino Toscano (6): tail: check the return value pf guestfs_set_pgroup 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 cat/tail.c

Hi, this patch serie adds a new GUID type in the generator, which would do the same as String, but also validating (just in the C output) the passed GUID string. This allows to reject invalid GUIDs before passing them to low-level tools. Pino Toscano (4): utils: add a function to validate a GUID string generator: add a GUID parameter type generator: generate code for parameter validation

The Python 3 bindings currently are unable to deal with non UTF8 characters. This series continues what proposed in RHBZ#1406906. A new function 'set_decode_error_handler' allows the User to specify how to deal with decoding errors. The default behaviour will be raising a UnicodeDecodeError. If the handler is changed to 'surrogateescape', non UTF8 characters will be escaped in a

This is only lightly tested at the moment. For context see: https://bugzilla.redhat.com/show_bug.cgi?id=1138203#c40 https://bugzilla.redhat.com/show_bug.cgi?id=1075143 https://bugzilla.redhat.com/show_bug.cgi?id=1075164 Note this is not a complete fix. At least one more libguestfs patch is required (to implement virDomainPtr in the python bindings). Plus a virt-manager patch. Rich.

This completes the implementation on the libguestfs side, allowing python-libvirt dom pointers to be passed to guestfs_add_libvirt_dom.

A hopefully cleaner implementation this time. It doesn't require any special insights into how libvirt-python is implemented. Instead, it requires a change to libvirt-python to add a .c_pointer() method: https://www.redhat.com/archives/libvir-list/2014-December/msg00615.html Rich.

Since v3: - Fix labelling over overlays (see 6/6) - Tested it with a test program which simulates what virt-manager will do. See the attachment here: https://bugzilla.redhat.com/show_bug.cgi?id=1075164#c7 Rich.

These 3 patches implement support for APIs which must accept a mountable, but don't update apis which must return mountables. Matt

By splitting up large C files we can make parallel compiles a bit faster. Rich.
