I created a new branch bb-10.2-ext. So the tentative data flow looks like this: 10.2---------->10.3 <---(once) \ ^ ^ \ | | \- bb-10.2-ext ---> bb-10.2-compatibility - 10.2 will be periodically merged to 10.3. - bb-10.2-ext will be periodically rebased on top of 10.2 - bb-10.2-compatibility will be periodically rebased on top of bb-10.2-ext. - bb-10.2-ext will be periodically merged to 10.3 - bb-10.2-compatibility will once (when it's ready) be merged or rebased to 10.3 Every time I rebase bb-10.2-ext on top of the current 10.2, I can merge bb-10.2-ext to 10.3 immediately, so we don't have to do double work. > > Other features that depend on your refactoring and need be in the compat > branch, can be pushed directly into 10.2-ext. Correct. Note, by refactoring I mean two things: - Moving pieces of the code from sql_yacc.yy as methods to LEX, sp_head, THD, etc. This is to avoid duplicate code in sql_yacc_ora.yy. - Some Type_handler related patches. > > Are there features that should not be in 10.2-compat but still depend on > your refactorings? Sanja and I are thinking of pushing MDEV-10141 Add support for INTERSECT (and common parts for EXCEPT) into bb-10.2-ext when it's ready. There will be more tasks, I think. > > On Dec 16, Alexander Barkov wrote: >> Hello Serg, all, >> >> A few weeks ago I created a new branch "10.3" and pushed >> essential patches needed for the compatibility project. >> >> It worked as follows: >> - In 10.3: >> git rebase origin/10.2 >> git push --force >> >> - In bb-10.2-compatibility: >> git rebase origin/10.3 >> git push --force >> >> >> Now as other developers start to push into 10.3, this won't work >> anymore.
