[Libvir] mark more translatable messages
by Jim Meyering 04 Feb '08

04 Feb '08

This change marks for translation some more messages. It adds a few new ones, too, e.g., replacing "domain" with _("failed to parse domain description") in two places. Likewise, there are some like this: - virXendError (conn, VIR_ERR_NO_MEMORY, "strdup"); + virXendError (conn, VIR_ERR_NO_MEMORY, _("strdup failed")); The two new grep invocations in Makefile.maint handle two situations: First, when the entire statement is on a single line (ends in ";"). The second grep (with -A1) is to get the diagnostics that appear on the line following the function name. Hence where the first line ends in ",". With checks like this, it's nice if you can assume no trailing blanks in the code base. IMHO, that would be a nice change to make soon, but it's more invasive. Enable more checks for unmarked messages; fix violators. * Makefile.maint (sc_unmarked_diagnostics): Check for more functions. * src/conf.c (virConfParseValue): Remove trailing space in diagnostic. * src/libvirt.c (do_open, virDomainMigrate): Mark diagnostics. * src/xend_internal.c (do_connect, xenDaemonDomainDumpXMLByID): Likewise. (xenDaemonDomainDumpXMLByName, xenDaemonCreateLinux): Likewise. (xenDaemonDomainMigratePerform, xenDaemonDomainDefineXML): Likewise. * src/xml.c (virXPathString, virXPathNumber, virXPathLong): Likewise. (virXPathBoolean, virXPathNode, virXPathNodeSet): Likewise. (virDomainParseXMLOSDescHVM): Likewise. * src/xmlrpc.c (xmlRpcValueNew): Likewise. (xmlRpcValueUnmarshalDictElement): Likewise.

[Libvir] virsh vncdisplay fix
by John Levon 03 Feb '08

03 Feb '08

I have an old HVM guest defined in 3.0.4, and now I'm running 3.1.2 and libvirt 0.4.0. The config looks like this: (domain (image (hvm (vnc 1) (vncdisplay 0) (device (vfb (location localhost:5900) (vncdisplay 0) (uuid ...) The libvirt code looks like this: 1757 /* Graphics device (HVM <= 3.0.4, or PV <= 3.0.3) vnc config */ 1758 if ((hvm && xendConfigVersion < 4) || 1759 (!hvm && xendConfigVersion < 3)) { 1760 tmp = sexpr_fmt_node(root, "domain/image/%s/vnc", hvm ? "hvm" : "linux"); So we don't see the 'vnc 1' at the top. But the code to parse device/vfb doesn't expect this config either: 1685 tmp = sexpr_node(node, "device/vfb/type"); The patch below replaces the later version check with something that copes correctly with the "upgrade" case. regards john 2008-01-15 John Levon <levon(a)movementarian.org> * src/xend_internal.c: fix VNC parsing of old Xen domains on newer Xen versions. diff -prauN libvirt-0.4.0/src/xend_internal.c libvirt-new/src/xend_internal.c --- libvirt-0.4.0/src/xend_internal.c 2007-12-17 15:05:27.000000000 -0800 +++ libvirt-new/src/xend_internal.c 2008-01-14 18:42:08.895060570 -0800 @@ -1371,6 +1371,7 @@ xend_parse_sexp_desc(virConnectPtr conn, unsigned char uuid[VIR_UUID_BUFLEN]; char uuidstr[VIR_UUID_STRING_BUFLEN]; int vif_index = 0; + int found_graphics = 0; if (root == NULL) { /* ERROR */ @@ -1683,6 +1684,7 @@ xend_parse_sexp_desc(virConnectPtr conn, if (tmp && !strcmp(tmp, "sdl")) { virBufferVSprintf(&buf, " <input type='mouse' bus='%s'/>\n", hvm ?

[Libvir] [PATCH] Pull vc-list-files from gnulib, and update.
by Jim Meyering 01 Feb '08

01 Feb '08

Now that I've added the vc-list-files script to gnulib, this patch makes libvirt's bootstrap pull it from there. Changes from the previous version of the script: I reintroduced support for mercurial (only lightly tested), and rearranged the directory-existence tests so git is first.

No, I wasn't able to get virt-manager running. Probably the same problems as you are having: building Python modules (specifically, libvirtmod.dll) which can work from the Win32 version of python, with gcc/MinGW, proves to be very hard.
