Description Philipp Wagner [:imphil] 2010-10-04 03:07:49 PDT
Since bug 463385 modified extensions/ to use PARALLEL_DIRS instead of DIRS for all extensions we have a race condition when doing parallel builds of schema-validation and xforms.

xforms (in adds schema-validation to its DIRS, causing it to be built twice in parallel (once from extensions/Makefile and once from extensions/xforms/Makefile). This may work from time to time, but generally gives errors like this one:

/home/philipp/src/mozilla-central/obj-debug/config/nsinstall -R -m 644 /home/philipp/src/mozilla-central/extensions/schema-validation/public/nsISVSchemaErrorHandler.idl /home/philipp/src/mozilla-central/extensions/schema-validation/public/nsISVSchema.idl /home/philipp/src/mozilla-central/extensions/schema-validation/public/nsISVSchemaLoader.idl /home/philipp/src/mozilla-central/extensions/schema-validation/public/nsISchemaValidator.idl /home/philipp/src/mozilla-central/extensions/schema-validation/public/nsISchemaDuration.idl /home/philipp/src/mozilla-central/extensions/schema-validation/public/nsISchemaValidatorRegexp.idl ../../../dist/idl
/home/philipp/src/mozilla-central/obj-debug/config/nsinstall: cannot make symbolic link /home/philipp/src/mozilla-central/obj-debug/dist/idl/nsISVSchemaLoader.idl: File exists

Neil, since you made this change initially, do you have an idea how to solve this? Or could you CC someone else that might know how? ;)
Comment 1 Philipp Wagner [:imphil] 2010-10-04 03:11:50 PDT
ah wrong bug, I meant bug 462381 and that means Mitchell instead of Neil. The question above stays the same. Sorry for the confusion.
Comment 2 2010-10-04 03:31:46 PDT
Ah, so xforms depends on schema-validation, and unconditionally builds it? Can you not remove schema-validation from your --enable-extensions list?
Comment 3 Philipp Wagner [:imphil] 2010-10-04 11:06:43 PDT
Thanks Neil, that seems to work indeed (simple and easy!) It only needs a small patch to the to remove the enforcement of that schema-validation dependency. I've attached a patch, but I'll do some more tests on different platforms before asking for review on this one.

Requesting approval2.0 because we need this for XForms to build reliably with Gecko 2.0.

Philipp, did you start try server build? That's good guarantee the patch is safe to checkin?
Comment 8 Philipp Wagner [:imphil] 2010-10-15 15:08:39 PDT
yes, it builds on all platforms.
