2:32 a.m.
This series mainly focuses on removal of virStringListAdd which tries
to promote the use of a string list without counter variable as a
dynamic array. This means that every operation counts the number of
elements and when used in a loop resutls in O(n^2) algorithms.
To discourage it's future buggy use remove the helpers completely.
The end of the series then replaces some libvirt helpers for string
lists by the glib equivalents.
Patches:
1-3,18,24-25,28: cleanups
4-6: fix buggy iteration and memory handling in qemuNamespaceUnlinkPaths
7: helpers for easy use of GSList + char *
8-17,19-20: Don't use virStringListAdd inside of loops and prepare for
removal
21: Remove virStringListAdd and virStringListRemove
22-23: Open-code and remove virStringListGetFirstWithPrefix
26-27: Replace virStringListHasString by g_strv_contains
29-34: Preparation and removal of virStringListLength
(mostly inefficient iteration)
35-37,40: Replace/reimplement virStringSplit(Count) by g_strsplit
38-39: Replace virStringListJoin by g_strjoinv
