[asterisk-users] Hierarchical Config file (re)writing (bug 8684)

[Steve Murphy]

Anyone remember the problem with writing out config files that had
#include directives in them? You'd get a single, flat config file when
you saved it back out. I have heard a few howls of complaint! (see bug
8684)

Well, I just checked in a fix for this into trunk. My simple tests say
it's working, but the "real thing" may say otherwise. It will re-write
the config file in question, and also re-write all the files included by
it. All will have the little header inserted at the top, revealing that
the file is generated. I only see a few places in the code where the
text_file_save function is called: in the manager (AMI) code, and the
voicemail app(-- if you are in realtime, I think.)

What might be different:

1. If you included the same file twice (or more), you will see that,
after it is rewritten to disk, now two different files are included (one
a copy of the first), and if changes are made to one, and not the other,
then they may not be the same anymore.

2. Blank lines between entries will get dropped. Sorry. If you really
like
blank lines, then include a comment of a blank line.

3. Comments preceded by a large amount of whitespace will probably have
most of the preceding space dropped. sorry. Start your or comment at the
beginning of a line, or immediately after statements, and you'll keep
the spaces that way.

4. Trailing comments will get dropped. Put your comments in front of a
variable definition, or in front of a category definition. Comments with
no variable decls or category decls (you know, the [general] type
stuff...) will not be attached to anything, and will be lost.

5. Right now, #exec lines will be written out, if they are included, but
their output will not be included in the saved set. (Well, you could
look in /var/tmp, but they aren't ref'd by anything.). But, I think you
just want #exec's to get repeated as you placed them. Their output is a
dynamic thing anyway...!


So, I ask those who were interested in seeing this kind of
functionality, to test it out in trunk and report the bugs via the bug
tracker. I know there are some who would like this in 1.4, and after we
toughen up the code in trunk, maybe we could call it a bugfix and get it
in 1.4, if that is the right thing to do.
