  "message": "Make globs compatible with hash-based ninja semantics\n\nPreviously, globs worked by having soong_build rewrite a ninja file\nthat ran the globs, and then dependended on the results of that ninja\nfile. soong_build also pre-filled their outputs so that it wouldn\u0027t\nbe immediately rerun on the 2nd build.\n\nHowever, the pre-filling of outputs worked for ninja, because although\nit updated their timestamps, the soong ninja file was then touched\nby soong_build after that, so the soong_build ninja file was newer\nand ninja wouldn\u0027t rerun soong. But N2 reruns actions if their inputs\u0027\nmtimes change in any way, not just if they\u0027re newer. Similarly,\nhashed-based ninja implementations could not enforce an order on\nfile contents, so they would have the same problem.\n\nTo fix this, lift the glob checking out of ninja and into soong_ui.\nSoong_build will output a globs report file every time it\u0027s run, and\nevery time soong_ui is run it will check the globs file, and if any\nglobs change, update an input to soong_build. soong_ui is essentially\ndoing what was done in ninja with bpglob actions before.\n\nBug: 364749114\nTest: m nothing, m nothing again doesn\u0027t reanalyze, create a new file under a glob directory, m nothing again reanalyzes\nChange-Id: I0dbc5ec58c89b869b59cd0602b82215c4972d799\n",
