[libvirt] [PATCH v4 0/5] qemu: add virQEMUBuildBufferEscapeComma in qemu_command.c
Changes in v4: Changes made in v2 anbd v3 to qemu_command.c are discarded. Some changes introduced in v2 are used to create new smaller patches. virQEMUBuildBufferEscapeComma was applied to: - info->romfile in qemuBuildRomStr - disk->vendor and disk->product in qemuBuildDriveDevStr - fs->src->path in qemuBuildFSStr - fs->dst in qemuBuildFSDevStr - cfg->vncTLSx509certdir in qemuBuildGraphicsVNCCommandLine - loader->path and loader->nvram in qemuBuildDomainLoaderCommandLine Changes in v3: virQEMUBuildBufferEscapeComma was applied to: - src->hosts->socket in qemuBuildNetworkDriveURI - src->path, src->configFile in qemuBuildNetworkDriveStr - disk->blkdeviotune.group_name in qemuBuildDiskThrottling - net->data.socket.address, net->data.socket.localaddr in qemuBuildHostNetStr - dev->data.file.path in qemuBuildChrChardevStr - graphics->data.spice.rendernode in qemuBuildGraphicsSPICECommandLine - smartcard->data.cert.file[i], smartcard->data.cert.database in qemuBuildSmartcardCommandLine Link to v3: https://www.redhat.com/archives/libvir-list/2018-April/msg00053.html Changes in v2: virQEMUBuildBufferEscapeComma was applied to: - info->romfile in qemuBuildRomStr - disk->vendor, disk->product in qemuBuildDriveDevStr - fs->src->path in qemuBuildFSStr - fs->dst in qemuBuildFSDevStr - connect= in qemuBuildHostNetStr - fileval handling in qemuBuildChrChardevStr - TYPE_DEV, TYPE_PIPE handling in qemuBuildChrChardevStr - cfg->vncTLSx509certdir in qemuBuildGraphicsVNCCommandLine - cfg->spiceTLSx509certdir in qemuBuildGraphicsSPICECommandLine - loader->path, loader->nvram usage in qemuBuildDomainLoaderCommandLine Link to v2: https://www.redhat.com/archives/libvir-list/2018-March/msg00965.html Sukrit Bhatnagar (5): qemu: Escape commas for qemuBuildRomStr qemu: Escape commas for qemuBuildDriveDevStr qemu: Escape commas for qemuBuildFSStr and qemuBuildFSDevStr qemu: Escape commas for qemuBuildGraphicsVNCCommandLine qemu: Escape commas for qemuBuildDomainLoaderCommandLine src/qemu/qemu_command.c | 47 +++++++++++++++++++++++++++++------------------ 1 file changed, 29 insertions(+), 18 deletions(-) -- 1.8.3.1

I had earlier tried the conversion to virConfGetValue* functions listed in Code Cleanup tasks. I had a few issues there: - in the enum virConfType, there no value for Int and UInt. - in the function virConfGetValueInt and virConfGetValueUInt, the value is checked for types LLong and ULLong, which would always result in an error. I think maybe some datatypes need to be added to the virConfType and appropriate type must be assigned in virConfValue.
BTW: All your patches appeared as would a reply-to in the series, I think that may be because of not using --no-chain-reply-to on the git send-email or git format-patch command line.
In my ~/.gitconfig I have:
