Scrutinizer reported a minor error in a test involving a module
which I was not changing.
Styles/Conditional function setConditions can take a scalar or an
array as a parameter, but DocBlock says it only expects array.
I did not wish to add the extra module to my PR, but made a note to
self to fix that after PR was installed.
That has now happened, and it makes for a good case for me
to see all the PHP8/Composer2/etc. changes that have happened recently.
The condition is FALSE if the cell does not exist in the flipped table,
but anyway, it is sent in to a method requiring 'string' type, causing
it to fail.
Issue has been marked stale, but ...
Sylk read sets worksheet title to filename (minus .slk).
If that is >31 characters, PhpSpreadsheet throws Exception.
This change truncates sheet title, as Excel does, to 31 characters.
* Replace voku/anti-xss with ezyang/htmlpurifier. Despite anti-xss being a smaller footprint dependency, an a better license fit with our MIT license, there are issues with it's automatic it sanitisation of global variables causing side effects
* Additional unit tests for xss in html writer cell comments
This had been intended to get 100% coverage for TextData functions, and it does that.
However, some minor bugs requiring source changes arose during testing.
- the Excel CHAR function restricts its argument to 1-255. PhpSpreadsheet CHARACTER
had been allowing 0+. Also, there is no need to test if iconv exists,
since it is part of Composer requirements.
- The DOLLAR function had been returning NUM for invalid arguments. Excel returns VALUE.
Also, negative amounts were not being handled correctly.
- The FIXEDFORMAT function had been returning NUM for invalid arguments. Excel FIXED returns VALUE.
* Apply Column and Row Styles to Existing Cells
This is a fix for issue #1712.
When a style is applied to an entire row or column, it is currently
only effective for cells which don't already contain a value.
The code needs to iterate through existing cells in the row/column
in order to apply the style to them.
This could be considered a breaking change, however, I believe that
the change makes things operate as users would expect, and that the
existing implementation is incomplete.
The change also removes protected element conditionalStyles from
the Style class. That element is an unused remnant, and can no longer be
set or retrieved - methods getConditionalStyles and setConditionalStyles
actually act on an element in the Worksheet class.
Finally, additional tests are added so that Style, and in fact the
entire Style directory, now has 100% test coverage.
* Scrutinizer Changes
Scrutinizer flagged 6 statements. 5 can be easily corrected.
One is absolutely wrong (it thinks iterating through cells in column
can return null). Let's see if we can satisfy it.
* Remove Exception For CellIterator on Empty Row/Column
For my first attempt at this change, which corrects a bug by updating styles
for non-empty cells when a style is set on a row or column, I wished to make things
more efficient by using setIterateOnlyExistingCells, something which the
existing documentation recommends. This caused an exception to be generated
when the row or column is empty. So I removed that part of the change while I
researched what was going on.
I have completed that research. The existing code does throw an exception
when the row/column is empty and iterateOnlyExistingCells is true. However,
that does not seem like a reasonable action. This situation is analagous to
iterating over an empty array, and that action is legal and does not throw.
The same should apply here. There were no tests for this situation,
and now there are.
I have added additional tests, and coverage for all of RowCellIterator,
ColumnCellIterator, and CellIterator are all now 100%. Some of my new tests
were added in new members, because the existing tests all relied on mocking,
which was not the best choice for the new tests. One of the existing tests
for RowCellIteratorTest (testSeekOutOfRange) was wrong; it issued the expected
exception, but for the wrong reason. I have added an additional test to
ensure that it fails "correctly".
The existing documentation says that the default value for
IterateOnlyExistingCells is true. In fact, the default value is false.
I have corrected the documentation.
* More Scrutinizer
I believe its analysis is incorrect, but this should silence it.
* DocBlock Correction
ColumnCellIterator DocBlock for current indicated it could return null
or Cell, but it can really return only Cell. This had caused Scrutinizer
to complain earlier.
* PHP8 Environment Appears to be Fixed
Cosmetic change to Doc member. I suspect there is a way to rerun all
the tests without another push, but I have been unable to figure out how.
* Fix for 3 Issues Involving ReadXlsx and NamedRange
Issues #1686 and #1723, which provide sample spreadsheets, are probably
solved by this ticket. Issue #1730 is also probably solved, but I have
no way to verify.
There are two problems with how PhpSpreadsheet is handling things now.
Although the first problem is much less severe, and isn't really a factor
in the issues named above, it is helpful to get it out of the way first.
If you define a named range in Excel, and then delete the sheet where
the range exists, Excel saves the range as #REF!. If there is a cell which
references the range, it will similarly have the value #REF! when you open
the Excel file.
Currently, PhpSpreadsheet discards the #REF! definition, so a cell which
references the range will appear as #NAME? rather than #REF!.
This PR changes the behavior so that PhpSpreadsheet retains the #REF!
definition, and cells which reference it will appear as #REF!.
The second problem is the more severe, and is, I believe, responsible
for the 3 issues identified above.
If you define a named range and the sheet on which the range is defined
does not exist at the time, Excel will save the range as something like:
'[1]Unknown Sheet'!$A$1
If a cell references such a range, Excel will again display #REF!.
PhpSpreadsheet currently throws an Exception when it encounters
such a definition while reading the file. This PR changes
the behavior so that PhpSpreadsheet saves the definition as #REF!,
and cells which reference it will behave similarly.
For the record, I will note that Excel does not magically recalculate when a
missing sheet is subsequently added, despite the fact that the reference
might now become resolvable. PhpSpreadsheet behaves likewise.
* Remove Dead Code in Test
Identified it after push but before merge.
This is a fix for issue #1735.
It adds tests for this situation, and similar situations involving
adding new sheets and accessing existing ones.
Coverage for Spreadsheet.php increases from 69% to 75% as a result.
There are no changes to code. Additional tests are added,
so that the following 6 items now have 100% test coverage:
- Comment
- DefinedName
- DocumentGenerator
- IOFactory
- NamedFormula
- NamedRange
All other Samples write to temporary directory. DefinedNames samples
write to main directory, which (a) means they aren't stored with others,
and (b) they aren't ignored by git so look like changed files.
The tests are also simplified by requiring Header rather than Bootstrap,
making use of Helper.
Issue #580 has gone stale since I started work on this.
Nevertheless, this implements an exportArray function as an
exact counterpart of applyFromArry.
I chose the name exportArray to avoid confusion with the existing
method getStyleArray, which does something completely different.
This change also increases coverage for all the Style classes to 100%,
with the exception of Style.php itself. There were several (unchanged)
places in Style.php where I did not have sufficient understanding of
what was supposed to be happening, so could not create tests.
All properties used by applyFromArray are exported by this method.
Note that conditional styles are not covered; this is consistent
with the fact that they are not covered by applyFromArray.
The method is implemented as a final public function in Style/Supervisor,
which calls abstract protected function exportArray1, which is implemented
in each of the subclasses, and which calls final protected
function exportArray2 in Style/Supervisor.
So exportArray is usable for any of the subclasses as well.
The new method is added to the documentation.
The existing documentation for applyFromArray was alphabetized to make
it easier to follow.
One property (Style quotePrefix) was added to the documentation.
Some Borders pseudo-properties (vertical, horizontal, and outline) were
documented as usable by applyFromArray,
but aren't actually supported - they were removed.
The documentation of the properties seemed to use setProperty and
getProperty fairly randomly - it now uses setProperty exclusively.
New constants were added for the textRotation "angles" used to create a
"stacked" cell. I felt that changing the readers and writers to use
these constants was beyond the scope of this change, but it is
on my to-do list.
Sheet View Settings Block should be 8-14 bytes long in BIFF8 Excel 97 according
to the open office file format documentation. However access to byte 10 and 12 is
not possible when record data is malformed, so getUInt2d throws notice.
* Improving Coverage for Excel2003 XML Reader
Reader/Xml is now 100% covered.
File templates/Excel2003XMLTest.xml, used in some tests, is *not*
readable by a current version of Excel. I have substituted a new file
excel2003.xml to be used in its place. I have not deleted the original
in case someone in future (possibly me) wants to see what it needs to
make it usable.
There are minimal code changes.
- Unused protected functions pixel2WidthUnits and widthUnits2Pixel
are deleted.
- One regex looking to convert hex characters is changed from a-z to a-f,
and made case insensitive.
- No calculation performed for "error" cell (previously calculation
was attempted and threw exception).
- Empty relative row/cell is now handled correctly.
- Style applied to empty cell when appropriate.
- Support added for textRotation.
- Support added for border styles.
- Support added for diagonal borders.
- Support added for superscript and subscript.
- Support added for fill patterns.
In theory, encodings other than UTF-8 were supported.
In fact, I was unable to get SecurityScanner to pass *any* xml which is
not UTF-8. Eliminating the assumption that strings might not be UTF-8
allowed much of the code to be greatly simplified.
After that, I added some code that would permit the use of
some ASCII-compatible encodings (there is a test of ISO-8859-1).
It would be more difficult to handle other encodings (such as UTF-16).
I am not convinced that even the ISO-8859 effort is worth it,
but am willing to investigate either expanding or eliminating
non-UTF8 support.
I added a number of tests, creating an Xml directory, and moving
XmlTest to that directory.
Pull Request had problems reading old invalid sample in the code
coverage phase, not in any of the other test phases, and not in
the code coverage phase on my local machine.
As it turns out, aside from being invalid, the sample
is much larger than any of the other samples. Tests have been
adjusted accordingly.
* Smaller Test File
Should eliminate need to avoid test during xml coverage.
* Break Up Style Test into Multiple Tests
Per suggestion from Mark Baker.
* Integrate AddressHelper Change
The introduction of AddressHelper introduced a conflict which needed to
be resolved. I wanted to test it locally before resolving. This required
me to add (unchanged) AddressHelper to my local copy. I hope this is
an okay manner of resolving the conflict.
* Weird Travis Error
XmlOddTest works just fine on my local machine, but Travis failed it.
Even worse, the lines which Travis flags don't even make any sense
(one was the empty line between two methods!).
This test is not essential to the rest of the change. I am removing
it from the package, and will attempt to re-add it when I have a chance
to sync up my fork with the main project.
The plan is to keep Travis for a short while, until we are confident that
GitHub Actions work well enough for us. And after that we can remove Travis
entirely.
There is a bunch of duplicated things but it allows us to maximize
parallelismt to have results as soon as possible.
API documentation generation is still missing.
