scarab's Issues

[bug] empty folders are not removed

If in OLD folder were some empty folders, which are not present in the NEW folder, Scarab won't remove them after patching, thereby leaving empty junk folders all around, which besides cluttering, can sometimes cause problems as well (as some games or programs check whether there is a folder and do something based on this).

Could Scarab be released under LGPL?

Hello,

Scarab works very well, out of the box. I would prove useful for smaller companies for delivering updates / patches. But GPL could restrict its usage.

Could Scarab be released under LGPL?

Generate a win32 .exe for automatic patching

1. Make builder generate a .exe with gui that will ask for the ORI directory to be patched, incorporating the data in the executable, with integrity check,
2. Include a .nfo, image .png and .ico for the gui with a link to your site for donation :)
3. generate a dot(.)backup directory with a copy of the old files before patching (a revert back function :),
4. check if files are missing/wrong version before patching (and sha2?)
5. show a progressbar with time approximation.
6. It should be possible to extract the data from the .exe so it can be used on an incompatible system (ie linux/mac)

Do you think it could be possible without too mutch work ?
Thanks

Zlib error

Hi, When I use your source code to build exe file but zlib is error (builder and patcher). Althought I used new zlib library.

Scarab not returning error codes.

Hello, I;m using scarab on my build tool, it doesn't return error codes when the task fails. It makes the process of automation difficult.

Could scarab achieve this?

[request] 7-ZIP support.

As 7-ZIP is a successor of ZIP, is newer and gives more compression ratio, thereby ZIP is obsolete, thus 7-ZIP support should be added instead of ZIP (or additionally).

Builder Error

Hi,
I have a problem is when I build diff file for 2 folder (source and destination), while executing EncodeDiffFile function have error (error code is 28), (it mean left space memory). This problem appear with some file.

[sharing positive impressions]

Thanks to this great and usefull tool, it regained half of free space on my HDD! :)

[bug] errors: Encoding error: Can't encode memory with xdelta. Error code: ♀ / Bad allocation / FAILED.

Something is wrong when trying to diff some pair of folders, it throws errors:

Encoding error: Can't encode memory with xdelta. Error code: ♀
Bad allocation.

or

Encoding error: Can't encode memory with xdelta. Error code: ♀
Encoding xdelta diff file game1/file1.dll.diff
Gathering SHA1 digests for files in old directory...
Creating registry file...
FAILED.

What's going on?

Perhaps the errors are more related to Xdelta than to Scarab? - since there are some big sized files (over 500mb) in both folders, which Xdelta has some troubles with? Perhaps updating Scarab with the newest version of Xdelta can fix the errors?
