* Bug 66425: Avoid exceptions found via poi-fuzzDominik Stadler2024-07-153-4/+31
| | | | | | | | | | | | Avoid a possible StackOverflowException This adds support of counting of the "nesting level" into the base EscherRecord and thus makes this existing limitation much more effective as it kicks in for more types of nested records. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=66374 git-svn-id: https://svn.apache.org/repos/asf/poi/trunk@1919256 13f79535-47bb-0310-9956-ffa450edef68
* Add initial support for SOURCE_DATE_EPOCHDominik Stadler2024-07-152-65/+96
| | | | | | | | | | | | | | | | This allows to create reproducible binary files without creation/modification-timestamp being set when environment variable SOURCE_DATE_EPOCH is set. See https://reproducible-builds.org/docs/source-date-epoch/ for the related specification. For now, we ensure that Zip-file entries set the modification time to 1970-01-01, which seems to be enough to make simple OOXML files reproducible. There are likely some other places where resulting files are not reproducible, some more testing will be necessary to identify other areas that should take this into account as well. git-svn-id: https://svn.apache.org/repos/asf/poi/trunk@1919236 13f79535-47bb-0310-9956-ffa450edef68

* HSSFWorkbook.getSheet(): Return first found sheetDominik Stadler2024-07-071-6/+7
| | | | | | | | | | | | | | | | We do not need to loop over all sheets always but should be able to return the first found sheet. This may change semantics for cases where there are multiple sheets where name only differs in case, but the JavaDoc did not state which one will be returned. All three implementations (HSSF, XSSF, SXSSF) now behave the same way. Closes #653 git-svn-id: https://svn.apache.org/repos/asf/poi/trunk@1918982 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | | | | | | | | SheetUtil.getDefaultCharWidthAsFloat() This functionality saw some regressions at times and thus should be verified via unit-tests.
