test_patch.sh [options] compare two folders, create and patch the first folder found and compare the result with the next folder found
|
|
-b | --base : base folder of versions
|
|
-c | --colorize : colorize output
|
|
-e | --encoding : (list of encoding algorithms) create patches with encoding algorithms given (could be 'raw'/'gzip'/'xz'/'zeros')
|
|
-h | --help : display this help and exit
|
|
-i | --ignore-identical: (y | n) compare file of old and new version before creating/applying/checking a patch (if file are same it's ignored, default is 'yes')
|
|
-k | --keep : keep template files and result
|
|
-o | --output : output trace. Verbosely list executed command (for terminal, use /dev/stderr instead of /dev/stdout=the standard command result)
|
|
-t | --tar : tar name of template files
|
|
-v | --valgrind : execute valgrind for each command
|
|
|
|
test_patch takes as input a "base folder" (-b) or a tar file (-t). In any case, these must contain 2 others folders representing a list of files representing two different versions to compare, with the goal of :
|
|
- creating a patch for each file found
|
|
- applying these patches on the files of the old version
|
|
- checking if the patched files are effectively the same as the corresponding files in the new version
|
|
test_patch will list alphabeticaly the content of the "base folder", and take the first folder found as the "old version" and the next as the "new version"
|
|
and will create a 'result folder' which contains patches and patched files (stored in base folder with the folder name "'new version'_PATCH")
|
|
|
|
test_patch will parse recursively the folder "old version", and create the corresponding tree in the result folder
|
|
|
|
test_patch will create a patch for each file found if the file :
|
|
- is a file (!). The folders are not "patched" but parsed recursively. No analyse are done on folder.
|
|
- exists in the new version at the same place in the tree
|
|
- file size is not 0 byte in old or new version
|
|
|
|
For each file, test_patch will encode the patch with the encoding algorithm given with the option (-e | --encoding).
|
|
This is a list, spaces separated, among the following encoding : 'raw'/'gzip'/'xz'/'zeros'/'any'. If this parameter is omitted, 'raw' is used.
|
|
|
|
The simple command line to test is :
|
|
./test_patch.sh -t basedir_quick.tar -c
