How can I grab my local changelist and send it to someone else in Perforce? More specifically, I would like to send unsubmitted changes from a local pending changelist to another user's pending changelist.
set P4DIFF=C:\cygwin\bin\diff.exe
p4 diff -du -c 12345 > patch-to-head.diff
# On Other machine
patch -p1 < patch-to-head.diff
I may be wrong on the env var there, and you might have to do some fixups on the diff file, but the general idea is that you generate a GNU Unified Diff, that you can send to people that can use GNU patch to apply it.
P4 now has native support for the shelve operation in 2009.2. Both the client and server need to be at least 2009.2 to use this.
Not sure exactly what you are trying to do, but you may also want to consider P4_Shelve. It allows you to put a load of pending changes away on a virtual shelf, and then grab them back again later. Depending on what exactly you want to achieve by sending a changelist to someone else, this could provide a part of the answer.
Linked from the P4Shelve site is P4Tar which may also be useful - this does all the packing on the client side so you just get left with a file you can send to someone else.
To shelve your pending changelist YOURCHANGE:
p4 shelve [-c YOURCHANGE]
The other user then does:
p4 unshelve -s YOURCHANGE [-c THEIRCHANGE]
In either case the "-c" arg can be omitted to use the default changelist instead. In the p4 shelve case it means a new changelist will be created and the files in your default changelist will be shelved into it; in the p4 unshelve case it means the shelved files from your changelist will be unshelved into the other user's default changelist.
Perforce 2016, osx. Diff for pending changelist:
mac:src user$ cl=123456 && p4 diff -du $( p4 files @=$cl | sed s/#.*// ) > $cl.diff
output: 123456.diff
Applying patch:
mac:src user$ patch -p0 < 123456.diff
