Does the library editor tool lock a file while editing it?

I am working in a git controlled evnvironment with several other

engineers. Currently we each have a local copy of our libraries that

are

sync'd through git. The problem of merging libraries files after a Git

pull is becoming excessive.

 

We'd like to store all files in a folder on an NFS server accessable

by

all users. The libraries would still be version controlled by git,

with

a periodic commits. When an engineer is editing a library, the file is

read only to all other users. the other users can view but not

concurrently edit the file.

 

does the eagle library editor tool lock open files?

 

If not, is it possible to easily integrate this feature? without any

other version control or check-out software.

Hello Jesse,

Don't worry about all the haters, you're doing the right thing using

serious revision control for your libraries.  I have worked at a lot of

companies and library mismanagement is the number one reason boards come

back not working.  I have over 1500 unique devices in my library and it's

been in SVN control since the beginning (over a decade now).

I would however recommend that you don't use an NFS mount but force

everyone to use revision control client to check out latest version to

their machine.  I think that is cleaner and you can then update your local

copy of the library at a time suitable for your project (which might not be

suitable for another).

The short answer is don't expect EAGLE to change it's behaviour.  And I'm

not sure I want it to.

Use your revision control client to get the effect you would like.  I

haven't used git but if SVN clients can be configured to auto-lock certain

files then certainly git should be able to do it.  If I lock the file using

SVN then no one else can get a lock on it.  And the file is read-only on

the file system until SVN gets a lock.  I think that is the effect you are

after.

That would be my advise.  Another reason for wanting a full update report

so you can see what has changed in the library under your feet -- that

would help you out greatly in your situation (see thread from a few days

ago on that topic).

Cheers,

James.

Git really has no concept of a central server, so there is nothing built in to do any kind of file locking.  Because you have your own copy of everything, it is assumed that you have absolute control over your copy and that nobody else can get to it, so no locking is needed.  It's the same with all distributed version control systems.

That said, apparently there is an access control layer that you can install over Git that gives you more of an SVN-like experience: Gitolite
