2017-11-25lsinitcpio: Attempt to estimate only decompression timeDave Reisner1-10/+10
Read time is constant between compression methods and we can't possibly estimate this accurately since reading the image from disk doesn't happen with kernel userland functions, but instead UEFI or 16-bit realmode capabilities. ref: https://bugs.archlinux.org/task/56417
2017-03-11lsinitcpio: avoid null byte warnings with bash 4.3Dave Reisner1-6/+14
On compressed images, bash 4.3 gets salty: $ lsinitcpio initrd.gz >/dev/null /usr/bin/lsinitcpio: line 78: warning: command substitution: ignored null byte in input /usr/bin/lsinitcpio: line 90: warning: command substitution: ignored null byte in input Tidy up all of our hexdump comparisons via command substitution to use process substitution instead.
2016-07-12use an associative array to build bsdcpio optionsDave Reisner1-11/+26
This prevents having unquoted expansion in the bsdcpio commandline
2014-12-28lsinitcpio: avoid setting TIMEFORMAT globallyDave Reisner1-1/+1
Not that it really matters, but let's scope this to where we actually care for the modified time output.
2013-12-24lsinitcpio: remove nonexistent showconfig longoptDave Reisner1-1/+1
Should have been removed as part of previous commit, as this was clearly just a typo.
2013-12-24include missing longopt --config in arg parserDave Reisner1-1/+1
Reported in FS#38264.
2013-12-22Add -l flag when using lz4 compressionDave Reisner1-4/+11
This isn't documented, but it's needed since the kernel lz4 support is based on the original streaming format and not the newer default. Use -l to force the legacy codec. Fixup lsinitcpio to support the older format, and, add a warning when the newer format is detected. Who knows when this will be "resolved" ...

2013-10-21lsinitcpio: separate decompression from archive readingDave Reisner1-3/+3
This essentially reverts 306dcbd7b21f8a680 which foolishly assumes that kernel and libarchive decompression support stay in sync. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2013-09-07lsinitcpio: return success based on echo, not hexdumpDave Reisner1-0/+1
The impetus for doing this was a bug in util-linux's hexdump which never saw a release. For uniformity, simply echo an empty line here. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2013-09-07lsinitcpio: add support for lz4 compressed imageDave Reisner1-1/+6
Note that this requires a very recent version of lz4 utilities as it uses lz4, and not the original lz4c tool, in order to be command line API compliant with other compression tools. See upstream discussions: https://code.google.com/p/lz4/issues/detail?id=83 Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2013-03-09lsinitcpio: shortcut lzop involvement to bsdtarDave Reisner1-8/+4
libarchive 3.1 supports LZO now, so we no longer need this indirection everywhere. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2013-01-21Do more to determine the color caps of the termDave Reisner1-16/+1
823e24 wasn't really correct, since running 'tput setaf 0' effectively sanity checks the terminfo as well as checking existance. However, it does nothing to affirm that the terminal is capable of supporting colors. Moreover, *never* fall back on the hardcoded escapes as doing so implies that we've found a broken terminfo and we have no idea what the terminal is capable of doing. This reverts commit 823e2454176d4381cd3acc30481e9d84cdc298b1.
2013-01-13factor out kver detection to functions fileDave Reisner1-4/+1
This leaves bash completion with a duplication, but this is intentional to avoid pulling in the entire functions file and worrying about pollution. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-11-26lsinitcpio: use compound command for parseopts execDave Reisner1-3/+1
Pedantic, but at least this makes us consistent with mkinitcpio. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-10-07commit to some level of style in variable namingDave Reisner1-56/+53
This is an ugly patch, and probably does more than I'd like it to. The idea is that mkinitcpio adopts some sort of consistent style which I'm actually happy with. I define 3 kinds of variables: 1) local variables: all lower case, and scoped within functions. Use freely, as they're well contained. 2) global variables: these are known to mkinitcpio internally, but are global in scope. They mainly carry runtime configuration and collected data during the image generation process. These are always lower case, but carry a leading underscore to denote that they're global. 3) "API" variables: also global in scope, but exist "outside" of mkinitcpio -- either drawn in from the configuration file, or "exported" to the install hooks. These are always all upper case. When introducing new variables, extreme care must be taken to pick names that will not conflict with the environment inherited by mkinitcpio. A HACKING file is introduced with a similar description of the above, and more. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-09-30lsinitcpio: add -l, --list option; define as defaultDave Reisner1-5/+18
This is the default action for lsinitcpio. Add it just for the purpose of clarity. This change also separates out true options from 'actions' and validates that the user only passed a single action to lsinitcpio. Update the manpage accordingly. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-09-30lsinitcpio: add -c, --config option to dump configDave Reisner1-3/+9
Now that mkinitcpio stores the build time config file in the image, we should have a way of easily getting it back out. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-09-30lsinitcpio: move image analysis to separate functionDave Reisner1-66/+70
git (at least version 1.7.12.1) does a great job of showing the absolute wrong code moving around in this patch. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-07-15lsinitcpio: comment on why bsdtar alone isn't good enoughDave Reisner1-1/+3
I almost deleted this, replacing it with only bsdtar. Add a comment so I'm not tempted to do this again. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-06-08lsinitcpio: show only regular files as binaries0.9.2Dave Reisner1-2/+1
Show only regular files in /usr/bin instead of everything (including the mess of symlinks to busybox and kmod). It's also a nice to have since we're showing more about the multiple hook points now. This mostly restores the behavior prior to f7b8a6f0fd. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18lsinitcpio: Always show extraction timeDave Reisner1-2/+2
Even for uncompressed images, estimate the work being done to extract to ramfs. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18lsinitcpio: add support for listing new hooksDave Reisner1-21/+20
Read this out of the image config for -a output. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-18lsinitcpio: extract the image to a tempdirDave Reisner1-18/+45
We read the image a number of times. Extract the image to a temp directory so we can just extract it once and use the filesystem to our advantage. This requires a temp dir which we can nuke on an EXIT trap, but the whole operation is sped is a bit, especially for larger images. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2012-05-02lsinitcpio: fallback on 80 cols when tput failsDave Reisner1-0/+3
This only happens when the terminfo file is missing, but its a simple fix. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-04-22lsinitcpio: show file sizes in analyze outputDave Reisner1-3/+28
Always display the file size on disk, but also display the uncompressed size for compressed images. Borrows my own size_to_human function from paccache and elsewhere. Before: ==> Compressed with: gzip -> Compression ratio: .377 -> Estimated decompression time: 0.058s After: ==> Size: 2.67 MiB ==> Compressed with: gzip -> Uncompressed size: 7.07 MiB (.377 ratio) -> Estimated decompression time: 0.059s Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2012-02-20lsinitcpio: detect kver separate from modulesDave Reisner1-6/+4
mkinitcpio will always create /lib/modules/$kernver/kernel in the image, so we can use this to detect the kernel the image was built for, even if the image contains no modules. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2011-11-29lsinitcpio: columnize binaries outputDave Reisner1-3/+3
Now that we're including symlinks to busybox on the prebuilt image, this display needs a bit of tidying up. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2011-10-01lsinitcpio: disable color when stdout isn't a ttyDave Reisner1-1/+1
This was a copypasta error when taking this from makepkg, which has special concerns in this regard. lsinitcpio should only concern itself with stdout. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
