Doxygen isn't too good at documenting the parameters of a callback
within the documentation of a parameter that points to the callback.
A typedef provides a better place to document the parameters.
If the user chose File -> Save formatted document and typed the name
of an existing file, ELinks offered to resume downloading the file.
There are a few problems with that:
* save_formatted_finish does not actually support resuming. It would
instead overwrite the beginning of the file and not truncate it.
* When save_formatted calls create_download_file, cdf_hop->data
ends up pointing to struct document. If the user then chooses to
resume, lun_resume would read *(int *)cdf_hop->data, hoping to
get cmdw_hop.magic or codw_hop.magic. struct document does not
begin with any such magic value.
* Because ELinks already has the formatted document in memory,
resuming saves neither time nor I/O.
So don't show the "Resume download of the original file" button in
this situation.
In recent ELinks release announcements, I have described:
This release of ELinks is mostly licensed under version 2 of the GNU
General Public License. More permissive licences apply to some parts
of it, and there is also one test file under the GNU Free Documentation
License; please see COPYING for the list.
Remove that test file, so its GPL-incompatible licence need not be
mentioned in future announcements. The file however remains
downloadable as part of the elinks.git repository and releases like
elinks-0.11.6.tar.gz. Those should still be covered by the licence.
After the recent ecmascript_get_interpreter change, I got an assertion
failure in render_document, which calls ecmascript_reset_state and
then asserts that it has set vs->ecmascript != NULL.
ecmascript_reset_state cannot guarantee that because there might not
even be enough free memory for mem_calloc(1, sizeof(struct
ecmascript_interpreter). So, replace the assertion in render_document
with error handling, and likewise in call_onsubmit_and_submit.
This should fix a crash in:
at /home/Kalle/src/elinks-0.12/src/ecmascript/spidermonkey.c:251
at /home/Kalle/src/elinks-0.12/src/ecmascript/ecmascript.c:104
at /home/Kalle/src/elinks-0.12/src/viewer/text/vs.c:64
It seems that spidermonkey_get_interpreter failed and returned NULL to
ecmascript_get_interpreter, which did not check the return value and
behaved as if the ECMAScript interpreter had been properly initialized.
This caused destroy_vs to call ecmascript_put_interpreter, but
backend_data which should have been a JSContext * was NULL, causing
a crash in SpiderMonkey.
An alternative fix might be to make spidermonkey_put_interpreter skip
the JS_DestroyContext call if ctx is NULL. However, I think it is
better to make sure ecmascript_get_interpreter returns NULL if
spidermonkey_get_interpreter fails, so that vs->ecmascript is left
NULL and there's no chance that some other code might try to
dereference the (JSContext *) NULL.
Perhaps because of bug 981, if one opened hundreds of pages with
elinks --remote openURL(...), then ELinks 0.11.4 could crash with a
SIGSEGV in JS_InitClass called from spidermonkey_get_interpreter.
SpiderMonkey ran out of memory and began returning NULL and JS_FALSE
but ELinks didn't notice them and pressed on. Add some checks to
avoid the crash, although the underlying out-of-memory error remains.
The old code failed to write pending spaces before changing the
background color. That seems hard to fix without duplicating code,
and ELinks pads dumped lines to the requested width in these color
modes anyway, so this commit just makes ELinks write all spaces
immediately when colors are being used.
Try the following command before and after this commit:
elinks --no-home --eval "set document.colors.use_document_colors = 2" \
--dump-color-mode 1 --dump test/color.html
In DUMP_FUNCTION_SPECIALIZED, use isscreensafe_ucs (for UTF-8) or
isscreensafe (for unibyte) to detect control characters, and replace
them with spaces. add_document_to_string already did the same.
In DUMP_FUNCTION_SPECIALIZED (used by elinks --dump), detect the
second cell of double-cell (aka fullwidth) characters by comparing to
UCS_NO_CHAR, like add_document_to_string does. Don't use
unicode_to_cell for this any more.
Also, ignore the colors and attributes of the second cell; don't
output any escape sequences for them.
In start_document_refresh, use register_bottom_half instead of
install_timer if the timeout is 0 because install_timer asserts that it is
given a delay greater than 0.
Add a test case, test/refresh-0timeout.html. Note that
document.browse.minimum_refresh_time must be set to 0 to reproduce the
assertion failure.
Add a 'Search contents' button to the cache manager that searches
through the cache items' data rather than their metadata.
Add match_cache_entry_contents.
Add push_cache_hierbox_search_button and
push_cache_hierbox_search_contents_button, which call
push_hierbox_search_button after setting box->ops to either
cache_entry_listbox_ops or cache_entry_listbox_ops_match_contents,
respectively, which define the appropriate match callback for the
hierbox search code.
Add strlcasestr, used in the new match_cache_entry_contents routine.
Add an "Invalidate" button to the cache manager, which is useful when
a cache entry is locked and cannot be deleted but one does not want
ELinks to use that cache entry.
This is especially useful for showing that neither dump_truecolor_utf8
nor dump_truecolor_unibyte modifies its static color[] variable and it
therefore does not matter whether those functions use the same array
or not.
With all the comments and macros needed for this, the source files
don't become much shorter, but anyway I hope they'll be easier to
maintain this way.
This code was included in four variants of dump_to_file().
Move it to a new function dump_references() and make dump_to_file()
then call that. This makes the code size a little smaller.
The time cost will be negligible.
Instead of having four separate function definitions, have just one
sprinkled with #ifdefs, and #include that four times. The purpose
being to make it clearer which parts of these functions are identical
and which ones differ.
As a side effect, this change makes ELinks ignore --dump-color-mode
when dumping in UTF-8. Colourful UTF-8 dumping has not been
implemented and the fallback is now different from before.
ELinks 0.12pre4 has already been released and will not be modified.
Eventually, new changes will be made in ELinks 0.11.6.GIT and then
listed in this file. At that time, it would be wrong to claim that
0.12pre4 also includes the changes.
That was a remnant from the time when mkdist created a .git/HEAD
referring to the commit from which the distribution was made.
Nowadays, it creates git-commit-id instead.
