ricflams	c28d114b79	Guard against circular references in XRef tables/streams ... - Detect and prevent an xref table/stream at a certain offset from being read twice; malformed xref tables with circular references could otherwise cause the table-reading to loop forever. - Another approach could be to prevent TryReadTableAtOffset from changing the bytes' CurrentOffset to the lastObjPosition in its attempt to read a table (eg restore CurrentOffset after the attempt to read a Table) so the outer bytes-loop could continue its search through the entire bytes unaffected.	2025-10-01 06:32:38 +01:00
Richard Flamsholt	d7d01f842e	Update test Issue874: No longer missing a font ... Including the stream-xref means that the formerly missing font is no longer missing, so simply run the two test-cases under the (stricter) assumption of SkipMissingFonts=false.	2025-09-30 18:35:45 +01:00
Richard Flamsholt	33a8d829ee	Update test Issue874: Also more text on page 2 ... Page two has had four more characters added, which is now delected by this xref-stream fix	2025-09-30 18:35:45 +01:00
Richard Flamsholt	57921c7e9b	Update test Issue874: Now finds more text on page 1 ... With the fix for including associated streams, this test now finds more text on the first page. I've verified using Aspose.PDF and by viewing the ErcotFacts.pdf file being tested that yes, it was indeed missing part of the text before.	2025-09-30 18:35:45 +01:00
ricflams	5a6b3970f0	Add table-xref's associated stream-xrefs ... - If an XrefTable has an associated stream, as indicated via the XrefStm-property, then read and add that XrefStream - Any table can have 0 or 1 such associated streams - A caveat: such an associated stream might also theoretically be part of the Parts-sequence in which case it would be encountered both by looping through all those parts along with all the regular tables and now also by association to any of those tables. It doesn't seem harmful since the offsets are flattened eventually anyway and stored by their offset-key into a mapping-table.	2025-09-30 18:35:45 +01:00
ricflams	397ccb15d6	Add xref-streams tied to any parts, not just the first ... On a large sample of pdf-files PdfPig failed to read the correct StructTree-object for about 1% of them. The StructTree object was simply missing in the CrossReferenceTable.CrossReferenceTable. It turned out that the constructed CrossReferenceTable could miss Stream-parts if there were multiple Table-parts because a stream will only be added if it's associated with the very first Table-part. The remedy would seem to be to check for and add streams that are associated with any of the Table-parts, not just the first one. On a sample of 72 files where this failed, this changed fixed the StructTree for all of them.	2025-09-30 18:35:45 +01:00

Eliot Jones	07df6fd740	read last line of ignore file (#1155) ... * read last line of ignore file - do not cancel other matrix jobs if one test fails - read all lines of the ignore list even if it doesn't end with a newline - add ignore list for 0008 and 0009 * support missing object numbers when brute-forcing the file 10404 (ironically) contains not found references with number 43 0 for its info dictionary. changes brute-force code so that objects can be entirely missing * fix test since document is now opened successfully but mediabox is broken	2025-09-13 16:57:35 +02:00
Eliot Jones	c96880ac61	handle case where xobjects use same key as fonts (#1154) ... in document 10122 the font and xobject names are the same so the xobject overwrote references to the font for the page content, separate the dictionaries	2025-09-13 16:49:24 +02:00

Eliot Jones	dd5aa46c75	File buffering read stream investigation (#1140) ... * add test for filebufferingreadstream * #1124 do not trust reported stream length if bytes can be read at end the filebufferingreadstream input stream does not report more than the read length. the change to seek the xref in a sliding window from the end broke with the assumption that the reported length was correct. here we switch to reading the window or continue reading if we can read beyond the stream's initially reported length while seeking the startxref marker * remove rogue newlines	2025-09-07 14:39:46 +01:00
