2012-06-14Add some tools for testing ext4 performance and resiliency.Ken Sumrall
rand_emmc_perf is a simple test to test random read/write performance of emmc chips. android_emmc_perf_tests is a script that runs on the host that uses rand_emmc_perf to test the emmc performance on a device. corrupt_gdt_free_blocks is used to corrupt a filesystem so the kernel trips over it at runtime and panics, thus testing kernel's ability to mark the filesystem as needing to be fixed. set_ext4_err_bit sets the error bit in the superblock so e2fsck will trigger a full check next boot. corrupt_gdt_free_blocks and set_ext4_err_bit are only built for userdebug and eng builds. rand_emmc_perf is marked optional, and not included in any build by default.

2012-06-07atrace: enable running on user buildsJamie Gennis
This change allows atrace to be run on a user build, where it is not run as root. Some command line options still require root, and atrace will refuse to run if those options are specified when run as non-root. Bug: 6513400 Change-Id: I29984cb8a7c3ad80ba5fa6b031ed8ff81acabacf

adb bugreport > b & sleep 5; kill $? will show that a bunch of tools will SIGPIPE when trying to output data which is normal. We don't have a way on linux (bsd yes), to set NOSIGPIPE on the file desc passed down via fork/exec. Bug: 6447319 Change-Id: I1634a00a155fd8a3fd827aa4a77e94518534336c

2012-03-30Extend make_ext4fs() interface to allow callers to pass selabel_handle.Stephen Smalley
Extend make_ext4fs() to allow callers to pass an selabel_handle for labeling files in the ext4 image. Previously, this was only done via the _internal() function. This extends the library interface so that it can be used by the recovery and updater code for labeling files from OTA and update packages. Change-Id: I4f6755fe7c65b69587276d17ef5b971ebec0161f
2012-03-30Extend make_ext4fs to support setting SELinux security contexts in ext4 images.Stephen Smalley
Extend make_ext4fs with support for looking up the right security context from the file_contexts configuration and setting it in the generated image. This is similar to the existing support for looking up the UID/GID/mode via android_filesystem_config.h and setting it, but via configuration rather than defined in a header.

2012-03-29make_ext4fs: Allow custom filesystem configsKenny Root

2012-02-17Pass file descriptor instead of file nameAnatol Pomazau
Passing a file descriptor to make_ext4fs_internal() is more flexible. We can use tmpfile() to create a temporary file. tmpfile() is better than other solutions because it unlinks the file right after creating it, so closing fd effectively removes temp file. Thus we don't have to worry about large temp files accidently left on the filesystem in case of the program crash. Change-Id: Iba3758a0e13a898920d30d7fa5da696c22daa2b7

2012-02-16ext4_utils: simg2img: Add LOCAL_MODULE_TAGS in Android.mkScott Anderson
1) simg2img was being installed on the device. For the BUILD_EXECUTABLE add an "optional" tag (instead of the implied default of "user") so this does not happen. 2) In preparation of removing simg2img from user_tags.mk, add a "debug" tag to the BUILD_HOST_EXECUTABLE so it will be put in the host bin subdirectory for eng and userdebug builds.

2012-02-15ext4_utils: Fix LOCAL_MODULE_TAGS on img2simg and simg2imgScott Anderson
There were a few problems with the LOCAL_MODULE_TAGS here: 1) simg2img was being installed on the device. Add an "optional" tag for the BUILD_EXECUTABLE from the implied default of user so this does not happen. 2) In preparation of removing simg2img from user_tags.mk, add a "debug" tag to the BUILD_HOST_EXECUTABLE so it will be put in the host bin subdirectory for eng and userdebug builds. 3) img2simg was not being put into the host bin subdirectory by default. By changing the TAG from optional to debug, it is now put there for eng and userdebug builds. Change-Id: I3182781e78ffde2208644660d33b7eb068147561 Signed-off-by: Scott Anderson <saa@android.com>

2012-02-08Add img2simg tool that splits a large image into <n> sparse filesScott Anderson
img2simg can take a large binary and chop it into multiple sparse images. Each sparse image that is output has two chunks: a Don't Care chunk to offset to where the data should be placed, and a Raw chunk that actually contains the data to be placed there. So, for example, if you have a 12 GB random file that you want to place into userdata for testing e-MMC, you can run img2simg on it to chop it into multiple sparse files and then "fastboot flash userdata" on each of the sparse files. Usage: img2simg [OPTIONS] <raw_image_file> The <raw_image_file> will be split into as many sparse files as needed. Each sparse file will contain a single DONT CARE chunk to offset to the correct block and then a single RAW chunk containing a portion of the data from the raw image file. The sparse files will be named by appending a number to the name of the raw image file. OPTIONS (Defaults are enclosed by square brackets): -s SUFFIX Format appended number with SUFFIX [%03d] -B SIZE Use a block size of SIZE [4K] -C SIZE Use a chunk size of SIZE [64M] SIZE is a decimal integer that may optionally be followed by a suffix that specifies a multiplier for the integer: c 1 byte (the default when omitted) w 2 bytes b 512 bytes kB 1000 bytes K 1024 bytes MB 1000*1000 bytes M 1024*1024 bytes GB 1000*1000*1000 bytes G 1024*1024*1024 bytes Change-Id: I5593be1c195e04d83c99454e996763b841951dd7 Signed-off-by: Scott Anderson <saa@android.com>
