mwelch 97 July:
|
|
|
|
Before adding anything new to MSG_Prefs, consider whether your
|
|
new preference can best be managed using the prefs API directly.
|
|
If you are not getting the preference value often or otherwise
|
|
have no need to cache the prefs value, you are probably better
|
|
off calling the prefs API everywhere and leaving this object
|
|
alone.
|
|
|
|
Having said that, if you want to add a new member variable and
|
|
its access functions to MSG_Prefs, here is the way you want to
|
|
do this, in order to keep the world happy. (Specific conditions,
|
|
of course, may apply to your preference; the instructions below
|
|
apply to most circumstances.)
|
|
|
|
If a change in your preference does not need to trigger an immediate
|
|
action:
|
|
|
|
1. Put a call to PREF_Get{Int,Bool,Char,etc.)Pref in the Reload()
|
|
method for your member variable and its corresponding JavaScript
|
|
preference name. This should be the only way by which your
|
|
member variable is set.
|
|
|
|
2. Your Get() accessor function must call Reload() before returning
|
|
the member value. This is the way by which you can be assured that
|
|
the most recently set preference value
|
|
|
|
3. If you must have a Set() accessor, implement it in such a way
|
|
that it calls PREF_Set{Int,Bool,Char,etc.}Pref, instead of
|
|
setting your member variable directly. This way, the prefs API
|
|
(and the user's preferences.js file) is properly updated. The
|
|
new value circulates back using Reload() and Get() as
|
|
described above.
|
|
|
|
If a change in your preference requires an immediate response (alert,
|
|
change in behavior, etc):
|
|
|
|
1. Implement the preference as described above.
|
|
|
|
2. In MSG_PrefsChangeCallback, there is a top-level parse tree (looking
|
|
for names beginning with "mail", "news", or "netw"). Find the clause
|
|
corresponding to your preference name and add a condition with code
|
|
that needs to run when your preference changes. Even if the code that
|
|
runs within MSG_PrefsChangeCallback always reloads on its own, you
|
|
still want to leave a load call within Reload() in order to load
|
|
the initial value at startup time.
|
|
|
|
If you have a transaction that spans across several preference changes,
|
|
be sure to tell the right people so that we can someday have calls to
|
|
transactionalize preference changes. Currently, all we can do is respond
|
|
to changes to individual preferences.

// This preference is used to help decide when to perform one time tricks, based
|
|
// on the age of the current user profile.
|
|
|
|
// The theory is: On a fresh install (actually, the creation of a new user profile),
|
|
// we should never do any one-time upgrade tricks.
|
|
// On an install over a previous verison, we should run each of the upgrade tricks that
|
|
// haven't already been run, for each old profile.
|
|
|
|
// The first such example is dealing with the introduction of the imap delete messages
|
|
// model in 4.02. We wanted the imap delete model to be the default out of the box but
|
|
// we also wanted a painless upgrade for existing users who use the delete to trash model.
|
|
// The solution is to make the imap delete model the default but if you haven't run the
|
|
// IMAP delete model upgrade and you have a trash folder, then change the preference to the
|
|
// trash model. In either case, the profile age is now changed to reflect that we have made
|
|
// this upgrade, by setting the appropriate bit.
|
|
|
|
// We will do this in a bitwise manner, so that individual one-time tricks do not depend
|
|
// on the order in which we check for them.
|
|
|
|
// This preference should ALWAYS be written to the prefs.js file, unless the value is 0.
|
|
// A value of 0 indicates an upgrade from Communicator 4.0, in which no upgrades have ever
|
|
// been run.
|
|
|
|
// The value written out to the prefs should be the sum of all trick flags which have been run.
|
|
// On a fresh install, we automatically write out the following number:
|
|
// {sum of all flags used for an upgrade trick}
|
|
// We do this in config.js, in modules\libpref\src\init
|
|
|
|
// The default value (in all.js) should ALWAYS be 0. This is because if the preference isn't
|
|
// present in the prefs.js file, then it means the value is implicitly 0 (because we are
|
|
// upgrading from 4.0, and none of the one-time tricks have been run).
|
|
|
|
// So, when a new flag is added here, you should also modify "mailnews.profile_age" in config.js
|
|
// to be the following number:
|
|
// {sum of all flags used for an upgrade trick}
|
|
|
|
// The Flags
|
|
// see above for #definitions
|
|
// 0x00000001 (reserved for the imap delete model trick)
|
|
// 0x00000004 (reserved for migrating to IMAP subscription)
|
|
// 0x00000008 MSG_IMAP_DEFAULT_HOST_UPGRADE_FLAG (upgraded default host to new per host prefs)
|
|
//
|
|
//
|
|
// *(The special reserved upgrade flag is purposely not used for an upgrade anywhere, except in calculating
|
|
// the default value for all.js. This is because we always want the value of "mailnews.profile_age"
|
|
// written out to the prefs file -- it can NEVER take on the "default" value, or else it will be
|
|
// removed from prefs.js, and this will defeat the purpose of writing out the "current" profile age.
|
|
// If we were to ever upgrade, it would find the preference not written out, and assume that it is
|
|
// up-to-date.
|
|
// To ensure that it is always written out to the file, in the creation of the MSG_Master we will
|
|
// un-set this flag each time, so that on a fresh install, the preference will get written out.
