|
|---|
| 10 | #
|
|---|
| 11 | # to answer the question "can it rebuild itself?"
|
|---|
| 12 | #
|
|---|
| 13 | # We expect four arguments - first directory path, filelist
|
|---|
| 14 | # containing the files in this directory which we wish to compare,
|
|---|
| 15 | # second directory path, filelist for second directory.
|
|---|
| 16 | #
|
|---|
| 17 | # Yes, we could just compare everything in each tree, but the
|
|---|
| 18 | # filelist script knows about files it can reasonably ignore,
|
|---|
| 19 | # and this also allows us to build a sytem, boot it and get a
|
|---|
| 20 | # list of files, build a full desktop environment, and only then
|
|---|
| 21 | # build and boot the "can it build itself" test system and get
|
|---|
| [89a2b70] | 22 | # _its_ filelist.
|
|---|
| [dc526ea] | 23 | #
|
|---|
| 24 | # What this script aims to do:
|
|---|
| 25 | # ____________________________
|
|---|
| 26 | #
|
|---|
| 27 | # First, report files not in both builds.
|
|---|
| 28 | #
|
|---|
| 29 | # Then, confirm symlinks point to same targets.
|
|---|
| 30 | #
|
|---|
| 31 | # After that, compare individual files -
|
|---|
| 32 | # if different, run the file name through 'expected'
|
|---|
| 33 | # to pick out files that are unlikely to match (logs,
|
|---|
| 34 | # pids, fstab [assumes '/' is a different device each time],
|
|---|
| 35 | # count these as 'expected'.
|
|---|
| 36 | #
|
|---|
| 37 | # For whatever is left, check the file type - ar archives
|
|---|
| 38 | # have their members extraced and compared (every member has
|
|---|
| 39 | # a timestamp), gzipped files are compared beyond their
|
|---|
| 40 | # timestamp, binaries, at least those using shared libs or
|
|---|
| 41 | # which are shared objects, are copied and subjected to
|
|---|
| 42 | # --strip-debug. If files match at this stage, count them as
|
|---|
| [89a2b70] | 43 | # 'accepted'.
|
|---|
| [dc526ea] | 44 | #
|
|---|
| 45 | # As a last step for any file that doesn't match, copy it
|
|---|
| 46 | # through some perl regexps to "process" it (convert any
|
|---|
| 47 | # date, time, kernel-version information from standard formats
|
|---|
| 48 | # into tokens, then see if the tokensi match.
|
|---|
| 49 | #
|
|---|
| 50 | # For details of the regexps, see the tokenize function.
|
|---|
| 51 | # Those files that match after this are also counted as
|
|---|
| 52 | # 'accepted'. Note that I don't always start from the kernel
|
|---|
| 53 | # version that I'm going to build, so this copes with e.g. perl
|
|---|
| 54 | # files that hardcode the kernel version.
|
|---|
| 55 | #
|
|---|
| 56 | # We now have files that don't match. A few of these seem to be
|
|---|
| 57 | # common to all builds - some (members of) c++ libraries or ar
|
|---|
| 58 | # archives, a few programs which perhaps use some sort of c++ code).
|
|---|
| 59 | # The file name # is passed to the 'failure' function - these
|
|---|
| 60 | # recognized filenames are labelled as 'predictable FAIL:',
|
|---|
| 61 | # anything else is labelled as 'unexpected FAIL:'.
|
|---|
| 62 | #
|
|---|
| 63 | # output:
|
|---|
| 64 | # stderr - files only in one of the builds, failure messages,
|
|---|
| 65 | # and totals.
|
|---|
| 66 | #
|
|---|
| 67 | # farce-results - more details, including which files were treated
|
|---|
| 68 | # as expected differences, files where neither copy could be read,
|
|---|
| 69 | # files treated as accepted, with the reason (and member for ar
|
|---|
| 70 | # archives). This data is typically up to 100 characters wide -
|
|---|
| 71 | # sometimes it's a bit more, but it doesn't wrap too badly in a
|
|---|
| 72 | # 100 character xterm.
|
|---|
| 73 | #
|
|---|
| 74 | # farce-extras - diffs for the files, or members, that didn't
|
|---|
| 75 | # match. This file is to establish new regexps for picking up
|
|---|
| 76 | # date/time/kernel-version formats.
|
|---|
| 77 | #
|
|---|
| 78 | # farce-identical - the names of the files which are identical
|
|---|
| [89a2b70] | 79 | #
|
|---|
| [dc526ea] | 80 | # farce-substitutions - whenever using tokenizeanddiff results in a
|
|---|
| 81 | # difference being accepted, for both versions diff the before and
|
|---|
| 82 | # after versions to show what got changed. If the file is a binary,
|
|---|
| 83 | # the output may still be hard to read. Note that I _know_ glibc
|
|---|
| 84 | # version strings pass one of the regexps looking for a kernel version
|
|---|
| 85 | # - since I expect you to use the same version of glibc for each
|
|---|
| [89a2b70] | 86 | # build, this is not a problem.
|
|---|
| [dc526ea] | 87 | #
|
|---|
| 88 | # farce-differ - the names of the files which could not be treated
|
|---|
| 89 | # as matching (whether or not I regard the failure as predictable)
|
|---|
| 90 | # for possible input to ICA processing.
