svn - Subversion refactor trunk and still be able to merge changes to old branches -

-

what best practices in situation refactor trunk in svn cannot apply refactor older branches, yet still need able svn merge bugfixes trunk branches?

to ask question more (if helps - if can answer above, feel free ignore):

we want move maven going forward, still need maintain old releases - cannot touched except customer sanctioned changes , bugfixes.

so, need refactor our folder structures around in trunk per maven - src/main/java, src/main/webapp etc (its wtp project - src, webcontent instead of above).

but going forward, still need able svn merge older branches still in old folder structure.

is possible? best practices?

i know can apply changes trunk, , apply changes branch manually, result in lot of pain developers want avoid.

apologies if answered or obvious (i have thought be, feel i'm asking obvious question!)

thanks in advance, justin

if move things around can still use svn merge, not straight on. svn merge not track moved files.

at lowest level can merge on per file basis, if move complete subdirectories can merge each "untouched" subdirectories @ once. there more steps involved , need track manually things has been moved.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
