2015-08-30wic: use bitbake variable ROOTFS_SIZEEd Bartosh1
If bitbake image is referenced in .ks file and --size is not used there wic uses ROOTFS_SIZE variable to set minimum partition size. ROOTFS_SIZE is calculated in meta/lib/oe/image.py when rootfs is created. The calculation is done using other image parameters: IMAGE_ROOTFS_SIZE, IMAGE_ROOTFS_ALIGNMENT, IMAGE_OVERHEAD_FACTOR and IMAGE_ROOTFS_EXTRA_SPACE.

2015-08-30wic: implement getting variables from .env filesEd Bartosh1
Added functionality of getting variables from <image>.env files to BitbakeVars class. env files will be parsed if the directory with env files is known, i.e. when vars_dir attribute is set. Otherwise 'bitbake -e' output will be parsed. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-08-30wic: add default_image attribute to BitbakeVarsEd Bartosh1
New attribute is used when bitbake variable is requested without specifying image name. The attribute should be set from outside, for example when wic is called with '-e <image>' option.

2015-08-30wic: create new method _parse_lineEd Bartosh1
Moved code that parses one line of 'bitbake -e' output to separate method _parse_line. This method will be also used later to parse lines of .env files. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-08-30wic: add BitbakeVars classEd Bartosh1
Moved code of getting bitbake variables into separate class. Created singleton object of this class in the module namespace. Preserved existing API get_bitbake_var. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-08-30wic: remove undescore from function nameEd Bartosh1
Renamed __exec_cmd -> _exec_cmd as double underscores cause strange behaviour when function is called in class method. Python complains that __exec_cmd method(!!!) of the same class doesn't exist.

2015-08-24wic: Add plugin for hybrid iso imageMihaly Varga1
This plugin creates a hybrid, legacy and EFI bootable ISO image. The generated image can be used on optical media as well as USB media. Legacy boot uses syslinux and EFI boot uses grub or gummiboot (not implemented yet) as bootloader. The plugin creates the directories required by bootloaders and populates them by creating and configuring the bootloader files. The plugin adds an image file to the iso which contains the directory tree of the rootfs folder specified by the --rootfs argument or by the IMAGE_ROOTFS bitbake variable. Using the isohybryd tool, the created .iso image is enhanced by a MBR for booting from disk storage devices, consequently the provided iso image could be copyed directly by dd comand onto USB drive or could be burned to an optical media by using a suitable image burner. The plugin depends on parted, e2fstools, syslinux, grub, cdrtools, dosfstools and mtools program. Some of the functions in this plugin were inspired from bootimg-efi.py and bootimg-pcbios.py plugins implemented by Tom Zanussi.

2015-08-09wic: Report recipe name for native commandsEd Bartosh1
exec_native_cmd was modified to report recipe to build native programs. Pairs executable->recipe are hardcoded as it's not possible to obtain this information automatically.

2015-07-10wic: Set default set of bitbake variablesEd Bartosh1
Set default set of bitbake variables to the set of variables for the first parsed image. This allows wic to find proper bitbake varibale values if it's called with '-e <image>' even without specifying image in the call of get_bitbake_var. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2015-07-02wic: Remove __write_partition methodEd Bartosh1
Moved code of __write_partition to 'assemble' method. This way it should be more readable. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com>
2015-07-02wic: Refactor fstab update codeEd Bartosh1
Made the code to backup and restore fstab only if it's modified. Cleaned up the code. Made it more pythonic. Improved code readability by moving code from several tiny methods into one place. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com>
2015-07-02wic: Add --uuid partition optionEd Bartosh1
Added --uuid option to the configuration of wks parser. This option specifies partition UUID. The code to process it is already in place. It was implemented for --use-uuid option. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com>
2015-07-02wic: Fix naming conflictEd Bartosh1
Image file name is not unique for the partitions without label. This causes image being rewritten and used as a source for all partitions without label. Wic produces broken or incorrect result images because of that. Added wks line number to the image name to make it unique.
2015-07-02wic: Remove duplicated codeEd Bartosh1
Moved duplicated code of geting rootfs size out of prepare_rootfs* methods.
2015-07-02wic: Refactor prepare_empty_partition APIEd Bartosh1
Moved code out of prepare_empty_partition* methods to avoid code duplication. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com>
2015-07-02wic: Call methods better wayEd Bartosh1
Shortened code by using getattr to obtain a method to call for prepare_empty_partition_* and prepare_rootfs_* methods. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com>
2015-07-02wic: Get rid of useless variable 'image_rootfs'Ed Bartosh1

2015-07-02wic: Rename partition imagesEd Bartosh1
Renamed partition images into <final image>.p<partition number> This should make output directory look more organized and easier to understand. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com>

2015-07-02wic: Turn off debug output for 'bitbake -e'Ed Bartosh1
Switched debug level to 'normal' to prevent huge 'bitbake -e' output to go into wic debug output. This should help to make wic debug info much more clean and easier to read. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com>
2015-07-02wic: Remove annoing debug messageEd Bartosh1
Wic tries to find plugins in every layer and prints a message 'Plugin dir is not a directory or does not exist' if layer doesn't have plugin dir. It causes a lot of duplicated messages in the debug output, which makes it hard to find useful info there. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com>
2015-07-02wic: Include mount point into image reportEd Bartosh1
Wic doesn't show any information for the partition if label is not set. Fixed this by adding mount point to the report. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com>
2015-07-02wic: Refactor getting bitbake variablesEd Bartosh3
Wic gets bitbake variables by parsing output of 'bitbake -e' command. This implementation improves this procedure as it runs 'bitbake -e' only when API is called and does it only once, i.e. in a "lazy" way. As parsing results are cached 'bitbake -e' is run only once and results are parsed only once per requested set of variables. get_bitbake_var became the only API call. It replaces find_artifacts, find_artifact, find_bitbake_env_lines, get_bitbake_env_lines, set_bitbake_env_lines and get_line_val calls making API much more clear.

2015-06-11wic: Move validation of --ptable option to wks parserEd Bartosh5

2015-06-11wic: Set type GUID and UUID for partitionEd Bartosh1

2015-06-11wic: Refactored getting root device nameEd Bartosh4

2015-06-11wic: Fix format stringEd Bartosh1

2015-06-11wic: check if part_type is set only for msdos partition tableEd Bartosh1
Specifying partition type(GUID) makes sense for gpt partition table. Current code checks if part-type is specified and throws exception if it is. This makes sense to do only for msdos partition table. Signed-off-by: Ed Bartosh <ed.bartosh@linux.intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com>

2015-05-27wic: refactored processing of wic exceptionsEd Bartosh1
All wic exceptions are now inherited from new base exception class WicError. It makes them easy to maintain and catch. Processing of exceptions is done this way: Known wic exceptions cause wic to print error message to stdout. Unknown exceptions are not catched anymore and produce standard python traceback.

2015-05-23wic: Make sure file exists before removing itEd Bartosh1
Bunch of os.remove calls were added to the partition.py lately. They're causing wic to fail with OSError: [Errno 2] No such file or directory if file doesn't exist. Added check for file existence to all recently added calls of os.remove. That should fix this regression.
