Bug#762935: debsources: namespace qualified ctags
Package: qa.debian.org
Severity: minor
User: qa.debian.org@packages.debian.org
Usertags: debsources
[ originally reported by Olly Betts on #debian-devel ]
Ctags indexing is currently non-qualified, so indexing on OO langauges will not
contain class names, namespaces, etc.
To fix this we should add --extra=+q to ctags invocation. About this, the ctags
documentation says: "However, that this could potentially more than double the
size of the tag file".
Micro benchmarks:
- computation time is ~10-15% slower with +q
- size
- libreoffice (C++)
zack@tytso:~/ctags-bench/libreoffice-4.1.5$ wc ../libreoffice*ctags

zack@tytso:~/ctags-bench/linux-3.12.9$ wc ../linux*ctags

2610525 17780208 269391932 ../linux-3.12.9.extra+q.ctags
Bottom line: it's doable. (But will need to rerun all ctags indexing after
having changed the ctags plugin code.)
