1251a breaks -instance ?

Post by therube »

1251
vs
1250

i /think/ it was 1250 that i started with
i /think/ it was :: 1250: command line that worked (now, not so sure? though at the time, it seemed to work)

1251 breaks 1250: command line
& i think 1251 breaks command line too ?
i.e., the .db, Everything-MUSIC.db, is not being read?

what i wanted, was:
Everything-MUSIC.ini
Everything-MUSIC.db ...

:: 1251: cmd /c start .\everything.exe -instance MUSIC -read-only

:: 1250: cmd /c start .\everything.exe -instance MUSIC -read-only -config MUSIC

:: .\everything.exe -instance 15 -install-service


-


something like:
cmd /c start .\everything1251.exe -instance MUSIC -read-only -config MUSIC
creates an .ini file name, "MUSIC" - no extension at all
(& also creates a file named, "Plugins-MUSIC.ini)

(didn't look to see what the ".db"... might be, or do, or not ?)


(& all because of tindersticks ;-))

A bit more explanation, I guess...

Copy existing .db & .ini (& 1251.exe) into new directory
Rename .db .ini to Everything-MUSIC.ini (.db)
everything -install-service -instance MUSIC

everything -instance MUSIC -config MUSIC -read-only

That creates "MUSIC" (no extension, which is the .ini).
That does not read (pre)existing EVERYTHING-MUSIC.db

(gotta go...)

Thank you for the feedback therube,

Everything 1251 will force a rebuild.

Databases made with earlier versions of Everything are not compatible with Everything 1251.

I will try to avoid forcing a rebuild like this. (re-indexing properties is a pain)
However, there will be a few cases during development where Everything will require a rebuild.

For example, the (soon to be released) 1252 update will also require a rebuild as it fixes a major sorting issue with paths.
If I don't force a rebuild, you are likely to see the Corrupt database dialog.

I will make a note in the change log if the database will be rebuilt.

Also check your Tools -> Debug -> Statistics as it will usually show the reason for the rebuild. In this case it should show "Unsupported database version".

Is it useful to add the database version to the Statistics?

I did try that recently. It was removed as its adds to much confusion between the database version (currently 1.7.25) and the Everything version 1.5.0.1252a. I keep track of which Everything version has what database version so it not really useful information for the end user? .. I might be wrong though..

It would be useful information if Everything supported multiple database versions. However, that is unlikely to happen..

The idea came from opening older databases (everything.exe -db backup.db -readonly) where you might want to know what version was used at that time.

But you are right: not really useful information for the end user. I doubt if I was ever going to need this.

everything.exe -db backup.db -readonly
Unfortunately, if the version changes, this would fail with unsupported DB version.
With -readonly, Everything would not load or create a database at all. (empty database) Tools -> Debug -> Stats would report an empty database with the new version (not the version from the file specified with -db)

Forcing a rebuild with new database versions will be reduced as the stability for Everything 1.5a improves.

A little bit of history here:
Everything 1.3 development went from db version 1.6.7 to 1.7.8
Everything 1.4 development went from db version 1.7.8 to 1.7.20

db2efu reports the Everything database version.

OK, I see (adn even tried it). In that case there is no use adding the database version.
(and in the process I learned how to get the database version out of a everything.db, so I'm good :))
