[openZIM dev-l] support for bzip2 and zlib compression in zimlib will be dropped
by Tommi Mäkitalo 06 Jan '10

06 Jan '10

Hi, some days ago I talked to Manuel and we decided to drop bzip2 and zlib compression in zimlib. Lzma is successfully ported to the nanonote and we see no reason for supporting other compression methods any more. It will also reduce the depencency to zlib and libbzip2. I will still add a configure switch, where we can enable it but disable it by default. Tommi

[openZIM dev-l] [Bug 16] New: Version & Subversion ZIM format handling
by bugzilla-daemon＠openzim.org 06 Jan '10

http://bugs.openzim.org/show_bug.cgi?id=16 Summary: Version & Subversion ZIM format handling Product: openZIM Version: unspecified Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P1 Component: zimlib AssignedTo: tommi(a)tntnet.org ReportedBy: emmanuel(a)engelhart.org CC: dev-l(a)openzim.org Estimated Hours: 0.0 Currently, the zimlib is only able to deal with a specific version of the ZIM file format and otherwise generates an error. We want: * to be able to improve as often as possible the format. * to have a zimlib able to deal with a maximum of ZIM files (potentially with different ZIM format versions). ... consequently, the current implementation may be improved. We discussed about that during our last meeting and if I correctly remember the best proposition was IMO: * Introduce the concept of ZIM format subversion. * Zimlib can deal with all subversions of a specific ZIM format version. * If we want to add a feature which does not need to break the format, we increment the subversion counter and if necessary add subversion conditional code. * If we want to add a feature which need to break the backward compatibility, we need to increment the version counter. With such a system, the goal is to make as much as possible subversions and no new version (but this is another topic). -- Configure bugmail: http://bugs.openzim.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
