Uwe Schindler updated LUCENE-6995: ---------------------------------- Attachment: LUCENE-6995.patch > Add branch change trigger to common-build.xml to keep sane build on GIT > branch change > ------------------------------------------------------------------------------------- > > Key: LUCENE-6995 > URL: https://issues.apache.org/jira/browse/LUCENE-6995 > Project: Lucene - Core > Issue Type: Improvement > Components: general/build > Reporter: Uwe Schindler > Assignee: Uwe Schindler > Fix For: Trunk, 5.x > > Attachments: LUCENE-6995.patch > > > Currently build systems like Ant or Maven cannot correctly handle the > following typical Git workflow: > - You do some stuff, run some tests > - You quickly switch the branch to something else (e.g., master -> branch_5x) > - If you then run tests or compile, you get crazy error messages because all > the up-to-date checking does not work. To fix you have to run "ant clean" on > root folder. > The reason for this behaviour is how switching branches works: "it just > replaces your working copy with another verson and different file > modification dates (in most cases earlier ones!). This breaks Ant's and > Javac'c uptodate checking. > This patch will add some check to common-build (which is done before > "resolve" through a dependency of "init" task) to keep track of current > branch: > - It copies {{.git/HEAD}} into the build folder as "reference point". > - Before compiling (on init), it does a file compare of current HEAD file > with the clone in build dir. If it does not yet exists (clean checkout) or if > it is identical, it just proceeds > - If the file contents changed, it will trigger "ant clean" on the LuSolr > root folder automatically and print message. > The status is passed down to sub-builds using {{*.uptodate}} property, so the > check is only done once. > Robert an I tried this out in serveral combinations, works fine. > Any comments? -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
