CkZipEntry::ReplaceString() returns true but the zip file entry is missing from the zip file afterwards. This worked fine in 9.4.0 before upgrading to 9.4.1 SP1.

Code to reproduce:

shared_ptr<CkZipEntry> zipentry(zip.GetEntryByName(_T("docProps/custom.xml")));
CString csXml(zipentry->unzipToString(0, _T("utf-8")));
zipentry->ReplaceString((LPCTSTR)csXml, _T("utf-8"));

What strikes me is that the ChilkatLog says "Zip entry has null filename."

Thanks! I'm working on the problem.

The problem should be fixed. Here are new VC++ 11.0 builds with the fix:

Are these stable enough for production use?

P.S. I used the v110_xp builds...

Yes, they are stable enough for production use. I'll do the v110_xp builds later today and upload..

Thanks, but when will this be included in an official release?

(Aug 27 '13 at 09:07) roan98dk

Not for a while. v9.4.1 was just released, so these could be considered the same as v9.4.1 but with a patch applied. The Version property indicates the sub-version (such as v9.4.1.42).

(Aug 27 '13 at 15:10) chilkat ♦♦

What I meant is that, what if others have the same or related problems. How would the know that a patch is available if it is not posted on the release page?

(Aug 27 '13 at 15:21) roan98dk

Yes, I understand. The Chilkat blog has a pre-release category here:


It may always be a few fixes behind, mainly because I'm not going to post the fix until it's been thoroughly tested.

The v9.4.1 SP1 release also lists many of the fixes http://www.cknotes.com/?p=487

It's impossible to produce pre-release builds for all supported programming languages, operating systems, etc. It would take too much time. Therefore, if a pre-release is needed, it can be build and supplied upon request. It will only be possible to provide a pre-release at the latest version.

A suggestion would be to add a "known bugs" section to the release notes for SP1 or make it very clear that there could be known bugs and that the pre-release blog should be checked before downloading the official release. By the way this bug fix is not listed as pre-release with version number yet.

I am also using the AutoXcrc property of CkFtp2. Is the latest bugfix included in the above-mentioned pre-releases?
