37089 - Support external editing in composer (conflict dialog)

Status: VERIFIED DUPLICATE of bug 27820

(SeaMonkey :: Composer, enhancement, P1)

Description

[Charles Manske]

The user can edit a page in both Composer and an external editor at the same 
time. They can save changes to the file with an external editor.
When edit a file in Composer, we need to store the file timestamp and when
we receive focus in a Composer window, we need to check the file timestamp 
against the start time. This will allow detecting changes made by the external
editor. If the user has not made any changes in the Composer version while 
editing in the external editor, all we need to do is put up a "Yes" "No" 
message asking if they want to load the new file version.
If they made changes in the Composer version *and* in the external version and
then saved the external version, there is a conflict and the dialog needs to
be very explicit about telling user to choose one or the other version (the 
one in Composer memory or the version on disk.) We do exactly this in 4.7, so
please review the messages there to evaluate if the strings are ok to use
in mozilla.

The strings for this dialog should be decided in m16. Complete implementation 
may wait?

Putting on [nsbeta2-] radar. Not critical to beta2.  But feel free to check in 
prior to 5/16

Dialog work is done. Remaining is to get the file date when getting focus
on the document to detect if page was modified by an external editor.

be fixed

We can live without this for 1st release, since we don't access an
external editor from within Composer

setting to nsbeta3- since this is futured, also adding helpwanted to the 
keywords

Adding keyword: relnoteRTM, removing Simone from cc list and adding myself

Comment 12

[Eric Krock]

Nominating mozilla1.0 and nsbeta1 to trigger consideration for those releases 
since this appears to have been languishing in release notes since Netscape 6.0. 
When editing web pages using Nav4.7 Composer, I almost always have the file open 
simultaneously in Composer and a text editor (in my case, UltraEdit). Would be 
really nice if Mozilla Composer would support the same automatic detection of 
changes so I didn't have to keep track in my head of which one made the last 
change.

Checking a file timestamp, showing a dialog, and reloading from disk if the 
Composer version is older doesn't seem like a lot of code--could we get this in 
for nsbeta1/mozilla1.0?

Removing nsbeta* keywords from this bug since it's future and we have more 
important things to fix before implementing this functionality.
