[libvirt] [PATCH v2 00/12] Make auto completion better
v2 of: https://www.redhat.com/archives/libvir-list/2017-November/msg00213.html diff to v1: -cmdComplete reworked -Dozen of small improvements The command completion is still missing. I mean, 'virsh start<TAB><TAB>' will still give you list of --options rather than a list of domains to start with it. And honestly, the code is so ugly, that I haven't even tried to implement it. Be my guest. Michal Privoznik (12): vshCommandParse: Don't leak @tkdata vshCommandStringParse: Allow retrieving partial result vshReadlineParse: Escape returned results if needed vshCommandOpt: Allow caller avoiding assert() vsh: Fix vshCompleter signature vsh: Call vshCmdOptDef.completer properly vshCompleter: Pass partially parsed command vsh: Introduce complete command tools: Provide bash autompletion file virsh: Introduce virshDomainNameCompleter virsh: Introduce virshDomainInterfaceCompleter virt-admin: Introduce vshAdmServerCompleter configure.ac | 3 + libvirt.spec.in | 2 + m4/virt-bash-completion.m4 | 74 ++++++++++++++ tools/Makefile.am | 40 +++++++- tools/bash-completion/vsh | 67 +++++++++++++ tools/virsh-completer.c | 150 ++++++++++++++++++++++++++++ tools/virsh-completer.h | 41 ++++++++ tools/virsh-domain-monitor.c | 33 +++--- tools/virsh-domain.c | 186 +++++++++++++++++----------------- tools/virsh-snapshot.c | 24 ++--- tools/virsh.c | 5 +- tools/virsh.h | 7 +- tools/virt-admin-completer.c | 76 ++++++++++++++ tools/virt-admin-completer.h | 33 ++++++ tools/virt-admin.c | 13 ++- tools/vsh.c | 232 +++++++++++++++++++++++++++++++++---------- tools/vsh.h | 23 ++++- 17 files changed, 831 insertions(+), 178 deletions(-) create mode 100644 m4/virt-bash-completion.m4 create mode 100644 tools/bash-completion/vsh create mode 100644 tools/virsh-completer.c create mode 100644 tools/virsh-completer.h create mode 100644 tools/virt-admin-completer.c create mode 100644 tools/virt-admin-completer.h -- 2.13.6
When parsing cmd line which has "--" on it, this is leaked. Problem is, parser->getNextArg() allocates new string and stores it into tkdata. But as soon as "--" is detected 'continue' is issued without any free of the allocated memory. ==5304== 3 bytes in 1 blocks are definitely lost in loss record 1 of 782 ==5304== at 0x4C2AF50: malloc (vg_replace_malloc.c:299) ==5304== by 0x8BB5AA9: strdup (strdup.c:42) ==5304== by 0x55842CA: virStrdup (virstring.c:941) ==5304== by 0x172B21: _vshStrdup (vsh.c:162) ==5304== by 0x175E8E: vshCommandArgvGetArg (vsh.c:1622) ==5304== by 0x17551D: vshCommandParse (vsh.c:1418) ==5304== by 0x175F25: vshCommandArgvParse (vsh.c:1638) ==5304== by 0x130940: virshParseArgv (virsh.c:820) ==5304== by 0x130C49: main (virsh.c:922) Signed-off-by: Michal Privoznik <mprivozn@redhat.com> --- tools/vsh.c | 1 + 1 file changed, 1 insertion(+) diff --git a/tools/vsh.c b/tools/vsh.c index 10a65c39f..93291feeb 100644 --- a/tools/vsh.c +++ b/tools/vsh.c @@ -1494,6 +1494,7 @@ vshCommandParse(vshControl *ctl, vshCommandParser *parser) } } else if (tkdata[0] == '-' && tkdata[1] == '-' && tkdata[2] == '\0') { + VIR_FREE(tkdata); data_only = true; continue; } else { -- 2.13.6
In the future, this function is going to be called from vshReadlineParse() to provide parsed input for completer callbacks. The idea is to allow the callbacks to provide more specific data. For instance, for the following input: virsh # domifaddr --domain fedora --interface <TAB><TAB> the --interface completer callback is going to be called. Now, it is more user friendly if the completer offers only those interfaces found in 'fedora' domain. But in order to do that it needs to be able to retrieve partially parsed result.

When returning a string that needs escaping there are two scenarios that can happen. Firstly, user already started the string with a quote (or double quote) in which case we don't need to do anything - readline takes care of that. However, if they haven't typed anything yet, we need to escape the string ourselves.
