2022-04-06libmisc/untar: Use a larger block size to read and write filesChris Johns1-20/+33
- A larger block size lets files systems work better. On JFFS a 512 byte compressed block means lots of small flash updates Closes #4635
2022-03-22cpukit/libmisc/untar: Change license to BSD-2Joel Sherrill1-3/+22
Updates #3053.
2021-12-09untar: Make behavior similar to GNU or BSD tarChristian Mauderer1-20/+37
RTEMS untar implementation had problems with overwriting or integrating archives into existing directory structures. This patch adapts the behavior to mimic that of a GNU tar or BSD tar and extends the tar01 test to check for the behavior. That is: * If a directory structure exists, the files from the archive will be integrated. Existing files are overwritten. * If a file exists and the archive contains a directory with the same name, the file is removed and a directory is created. In the above example: if l1/l2 is a file it will be overwritten with a new directory. * If a directory exists and the archive contains a file with the same name, the directory will be replaced if it is empty. If it contains files, the result is an error. * An archive also can contain only a file without the parent directories. If in that case one of the parent directories exists as a file extracting the archive results in an error. In the example: if l1/l2 is a file and the archive doesn't contain the directories but only the file l1/l2/x.txt that would be an error. * In case of an error, it is possible that the archive has been partially extracted. Closes #4568

2016-08-09libmisc/untar: Set the perms to the value in the tar file.Chris Johns1-19/+28
This patch parses the mode field in the tar header and sets the directory or file to the mode value in the header. Closes #2768.

2016-06-03libmisc/untar: Support directory create and overwrites. Share the common code.Chris Johns1-126/+337
Support creating directories for files with a path depth greater than 1. Some tar files can have files with a path depth greater than 1 and no directory entry in the tar file to create a directory. Support overwriting existing files and directories failing in a similar way to tar on common hosts. If a file is replaced with a file delete the file and create a new file. If a directory replaces a file remove the file and create the directory. If a file replaces a directory remove the directory, and if the directory is not empty and cannot be removed report an error. If a directory alreday exists do nothing leaving the contents untouched. The untar code now shares the common header parsing and initial processing with the actual writes still separate. No changes to the IMFS have been made. Updates #2415. Closes #2207.
2015-11-23untar: do not exit with error when created directory already exists.Pavel Pisa1-1/+29
The problem exists for both RTEMS untar implementations and their variants: Untar_FromMemory(), Untar_FromFile() and rtems_tarfs_load(). If filesystem object already exists at extracted directory path then if it is directory, creation is ignored. Attempt to delete/unlink object and make directory is tried for other cases. This simple approach problem reported in ticket fixes #2413. Behavior follows GNU tar and BSD tar practice for directories but much more work is required to achieve full semantics of the full featured tar implementation still.
2015-01-04untar.c: Coverity ID 26151 and reformatJoel Sherrill1-295/+251
The Coverity issue was an ignored return value from a read() in a loop which should have been a seek() since the data read was ignored. The file itself needed reformatting to conform to RTEMS style.

2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-2/+0
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
