Hi,
Since r26476 I observed SIGABRT over ra_dav due to uncleared
error(--enable-maintainer-mode build), This commit seems to fix it.
Though I could not understand the fix or no mention of the same.
Refer merge_tests.py's
'avoid_repeated_merge_using_inherited_merge_info'. Commit of r5 was
causing this SIGABRT.
I could see the 'uncleared error to be' "File not found: transaction
'4-4', path '/A/B/E/alpha'".
In r26489 and pre-26476 this error does not happen.
Dav http request level difference between r26476 and r26489 is 'CHECKOUT
/svn-test-work/repositories/merge_tests-1/!svn/ver/1/A/B/E/alpha'
r26476 makes this 'CHECKOUT' req and gets the error which is not handled
and left uncleared.
Pre r26476 and r26489 does not make this extra CHECKOUT request and
hence no SIGABRT.
I could see in general this commit to be 're-org' type of commit except
few functional bits like 'remove_wcprops', though I could not connect
this changes to 'removal of one extra CHECKOUT'.
Can someone explain here?
With regards
Kamesh Jayachandran
