RE: reintegrate merge failing because "can only be used if revisions <snip> were previously merged", but it's a lie (I think?)

I really appreciate your help, but I'm still trying to comprehend.

If I do the `svn propdel -R svn:mergeinfo; svn revert .` in my branch, I wind up clearing out mergeinfo on 8000+ files:
 ( I collected a `svn pg svn:mergeinfo` before and after the operation. Using wc -l to get a sense of how much change happened)
[charletr_at_ariesbld DUAL_SSL_Inspection-mergeinfo-cleanup]$ wc -l mergeinfo.before.txt
8374 mergeinfo.before.txt
[charletr_at_ariesbld DUAL_SSL_Inspection-mergeinfo-cleanup]$ wc -l mergeinfo.after.txt
59 mergeinfo.after.txt

If I focus on looking into what changed for only the file that I used for an example at the start of this thread, I see that its mergeinfo is wiped out and not replaced.

[charletr_at_ariesbld DUAL_SSL_Inspection-mergeinfo-cleanup]$ grep ports/lsm/lsmclient/test/cukes/features/1_package_update mergeinfo.before.txt
ports/lsm/lsmclient/test/cukes/features/1_package_update - /6WINDGate/branches/zorro_trunk_merge/ports/lsm/lsmclient/test/cukes/features/1_package_update:21398-23471
/6WINDGate/production/aries_1.1.1/ports/lsm/lsmclient/test/cukes/features/1_package_update:21842,21867,21906,22087,22270,22334
/6WINDGate/trunk/ports/lsm/lsmclient/test/cukes/features/1_package_update:15746-19001,19597-25912
[charletr_at_ariesbld DUAL_SSL_Inspection-mergeinfo-cleanup]$
 [charletr_at_ariesbld DUAL_SSL_Inspection-mergeinfo-cleanup]$ grep ports/lsm/lsmclient/test/cukes/features/1_package_update mergeinfo.after.txt
[charletr_at_ariesbld DUAL_SSL_Inspection-mergeinfo-cleanup]$

The reason I find this confusing is because I assumed my goal is to get branch to undersand that a missing merge revision has actually been merged. This seems to go the other way and make branch forget a great deal of what has been merged.

Did you envision that my next step would be to check this in (to branch)? Or to merge trunk into branch again?

The suggestion related to a merge source path (a branch).
Also note the revert to retain the main mergeinfo.

These accumulate on actual merges on subtrees as well as copy operations to resolve tree conflicts. While it is a valid use case it is more likely to cause issues.
