1 I was having problems with `python test.py bugdir` with the Arch
2 backend. Commits were failing with `archive not registered'.
4 Adding some trace information to arch.Arch._rcs_init() and
5 ._rcs_cleanup() (the traceback module is great :p), I found
6 that the problem was coming from bugdir.BugDir.guess_rcs().
8 The Arch backend deletes any auto-created archives when it is cleaned
9 up (RCS.__del__ -> RCS.cleanup -> Arch._rcs_cleanup). This means that
10 whatever instance is used to init the archive in guess_rcs() must be
11 kept around. I had been doing:
12 * installed_rcs() -> Arch-instance-A
13 * Arch-instance-A.init()
14 * store Arch-instnance-A.name as bugdir.rcs_name
15 * future calls to bugdir.rcs get new instance Arch-instance-B
16 * eventually Arch-instance-A cleaned up
17 * archive dissapears & tests crash
19 I switched things around so .rcs is the `master attribute' and
20 .rcs_name follows it. Now just save whichever rcs you used to init
23 In order to implement the fix, I had to tweak the memory/file-system
24 interaction a bit. Instead of saving the settings *every*time* a
25 setting_property changed, we now save only if the .be file exists.
26 This file serves as a 'file-system-bugdir-active' flag. Before it is
27 created (e.g., by a .save()), the BugDir lives purely in memory, and
28 can freely go about configuring .rcs, .rcs_name, etc until it get's
29 to the point where it's ready to go to disk.
