Change in flashrom[master]: make args for -r/-w/-v non-positional and optional
by Arthur Heymans (Code Review) 20 Jan '18

20 Jan '18

Arthur Heymans has uploaded a new patch set (#8) to the change originally created by David Hendricks. ( https://review.coreboot.org/23022 ) Change subject: make args for -r/-w/-v non-positional and optional ...................................................................... make args for -r/-w/-v non-positional and optional Ported from chromiumos: https://chromium-review.googlesource.com/#/c/60515/ This makes a filename following -r, -w, and -v operations non- positional. The first argument that does not begin with a hyphen (-) is the filename for -r/-w/-v. If no such argument exists, then -r/-w/-v options apply to files specified for individually included regions via -i. This has a few side-effects: 1. It allows us to omit the ROM-sized filename entirely when a filename is provided for a particular region when using -i. For example, "flashrom -i FOO:foo.bin -r". 2. It allows, for better or worse, the filename be specified anywhere on the command line after the program name. Our scripts and docs should still specify the file after -r/-w/-v for clarity. For our purposes, if a filename is given for every included region (-i region:filename) then the user does not need to specify a filename after -r/-w/-v. However, if any -i option does not specify a filename, then a file must be specified after -r/-w/-v. The syntax will be backwards compatible for now so that one can still mix -i options with and without the added filename specifier for each region. BUG=chromium:263495 BRANCH=none TEST=manual (see notes below) 1. Write random data to RW_UNUSED region (on snow in this case) without requiring an argument to -w. See that only RW_UNUSED is erased and written, and that verify works: dd if=/dev/urandom of=rw_unused.bin bs=1k count=1 conv=notrunc flashrom -p host -i RW_UNUSED:rw_unused.bin -w -V flashrom -p host -i RW_UNUSED:rw_unused.bin -v -V 2.

Test that dumping RW_UNUSED and GBB regions without -r arg dumps two files and that they can be used to verify the content: flashrom -p host -i RW_UNUSED:rw_unused.bin -i GBB:gbb.bin -r flashrom -p host -i RW_UNUSED:rw_unused.bin -i GBB:gbb.bin -v 4.

Change in flashrom[master]: make args for -r/-w/-v non-positional and optional

Nico Huber has posted comments on this change. ( https://review.coreboot.org/23022 ) Change subject: make args for -r/-w/-v non-positional and optional ...................................................................... Patch Set 7: Code-Review-1 (1 comment) It's moving into the right direction. But I'd still like to have that discussion about CrOS interface compatibility. If we decide to uncon- ditionally keep that (over possibly better interface choices), that's a very influental decision for the project. And shouldn't be made in a review. Just imagine how fast this change could have been done for flashrom proper if we'd just kept the idea (per region files) and implemented it consistently with good old flashrom quality. I'd estimate a third of the time we already spent so far for gathering old commits, poli- shing, discussing. https://review.coreboot.org/#/c/23022/7/cli_classic.c File cli_classic.c: https://review.coreboot.org/#/c/23022/7/cli_classic.c@347 PS7, Line 347: char ** argv_copy = malloc((argc + 1) * sizeof(*argv_copy)); I'm not fully awake yet. Though, can't you just use argv + optind instead of a copy? Either way you don't seem to reset `optind`, so the copied `argv[j]` with `j < optind` won't be considered by getopt_long() anyway. Which is just fine. But makes this code a hell to follow... -- To view, visit https://review.coreboot.org/23022 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Iefbcb7dc4fefe26f5afd1292dfd5c1687fa62803 Gerrit-Change-Number: 23022 Gerrit-PatchSet: 7 Gerrit-Owner: David Hendricks <david.hendricks(a)gmail.com> Gerrit-Reviewer: Arthur Heymans <arthur(a)aheymans.xyz> Gerrit-Reviewer: David Hendricks <david.hendricks(a)gmail.com> Gerrit-Reviewer: Louis Yung-Chieh Lo <yjlou(a)chromium.org> Gerrit-Reviewer: Nico Huber <nico.h(a)gmx.de> Gerrit-Reviewer: Paul Menzel <paulepanter(a)users.sourceforge.net> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Comment-Date: Sat, 20 Jan 2018 13:19:25 +0000 Gerrit-HasComments: Yes Gerrit-HasLabels: Yes
