Instead of using ~/.mu, use the XDG Base Directory Specification, typically:
~/.cache/xapian
~/.cache/mu.log
~/.cache/parts
~/.config/bookmarks
Update dependencies, documentation.
When you have multiple mu home directories, e.g. for the use case
detailed in my "Changing mu4e-{maildir,mu-home} from a context hook"
post to the mailing list it's quite inconvenient to have to hammer out
"mu --muhome=.. find .." every time you want to run some ad-hoc
command.
This allows me to set up a screen session where I do searches in mu
directory A in some screen panes, and searches in directory B in
others.
I initially called this MU_MUHOME but then I noticed that the perl
plugin has MUP_MU_HOME for analogous functionality, so I'm just
following its example.
The code I'm adding in mu-util.c is just a copy/paste & adjustment of
the same sort of already tested functionality in
mu_util_guess_maildir() just a few lines earlier.
If not, when the session of mu is killed, these child processes are also
killed. This scenario shows up when using mu4e: a PDF attachment, for
example, is opened by Evince, but as soon as Emacs exits, Evince is also
killed.
mu_util_fputs_encode was aborting on behalf of the stack-guard on
OpenBSD (seemingly only when compile with optimization). It appears as
if the root cause of this was a differences in sizes of the parameters
to g_locale_from_utf8. Fix this.
Some users were report seeing get_uid_term high in the profiles; so
optimize this:
- make mu_util_get_hash a static inline function (used by get_uid_term)
- don't use 'realpath' in get_uid_term, seem that's the main culprit
- some slight faster string handling there too.
it seems g_locale_from_utf8 behaves a bit differently on bsd/macosx,
causing a segfault (but when run under gdb!). this code path was hit
for messages with encoding problems in non-utf8 locales
