tabbing_back_to_the_same_field_then_saving_keeps_the_committed_value (its
same-frame case) and typing_and_saving_in_the_same_frame_saves_the_last_keystrokes
both asked scratch() for "same-frame". The tests of the it binary share one
process id and run in parallel, so they got the same folder, and one could
clear it while the other was saving into it: the save then failed to read
back with NotFound. scratch() now adds a number taken per call.
fix(xfdf, sign, preflight, engine, forms, measure, annot): bound repeated work in form exchange, preflight and export, and check what imports and time stamps claim
Every packaging script runs under bash, so [[ ]] is available. Name the positional
parameters of sha256, render and has, end env.sh's functions with an explicit return
(bare, so the exit status is unchanged), and give the build-label case a default arm.
vendor/ is third-party code kept close to upstream (vendor/README.md), so SonarCloud's
186 findings there are not ours to restyle. MD5 in crates/crypt is what ISO 32000's
standard security handler mandates, and RIPEMD-160 in crates/sign is a digest existing
signatures can name; both S4790 findings are scoped to those two files.
Extraction walked the name tree again with a fresh key budget, so keys
the listing had left out could fill it and a listed embedded file came
back as not found. The lookup compares each key with the one wanted and
keeps none, so it needs no budget; a key object or /Names array that
several places reference is converted once.
A kept web address or attachment text spent only its converted length,
so a long raw value that trimmed short was converted in full for every
entry sharing it. A kept conversion now spends the longer of its raw
and converted lengths.
The embedded-files name tree copied every key, and an attachment
without a file name copied its key again as the name, so many entries
sharing one long key string multiplied it. Keys, and a key kept again
as the name, now spend the 16 MiB link and attachment text budget; an
embedded file whose key does not fit is not listed.
An annotation attachment's /Contents was read and charged to the text
budget before the file specification's /UF or /F, which then named the
attachment, so the discarded text could leave a later web address
unlisted. /Contents is now read only when neither name is there.
A web address or attachment text that converted to more than the budget
left spent nothing, so every link or attachment sharing it converted it
again. A conversion that comes out too long now spends the raw length,
and so does attachment text that trims to nothing.
The fixture's image stream held six bytes under /Length 4, and the test
only checked that the picture was missing at a zero budget, which a
picture that could not be prepared also passes. The stream is four
bytes, and the picture is first shown to export at a 1 MiB budget.
The link and attachment listings copied a link's web address and an
attachment's name and description for every annotation or name-tree
entry, so many entries sharing one long string multiplied it in
memory. Together they keep at most 16 MiB of that text, and a string
past what is left is not converted. A link past it lists as a URI
action without its address, an attachment under its generic name
without a description.
The annotation listing skipped a repeated /Annots entry by its raw
reference, so an indirect object holding only a reference to a link
listed that link a second time. Entries and page arrays are now told
apart by the object their reference chain ends at. The lopdf reader
reported the first object of a chain, because lopdf's get_object
already follows it; it now reports the last, as the lazy reader does.
A /Kids array listing one widget many times, or shared by several fields,
built a Widget for every listing, so a small file expanded into fields times
listings widgets. A widget now belongs to the first field that lists it, and a
page widget already owned is not adopted again.
The tests each branch appends to the audit, edit and organize test files are
kept side by side; prune.rs merges cleanly, with the form memo on top of the
budgeted page content.
