You may not always know which schemes are available.
The library should not bail out, but only show
an informal message. It's the responsibility of
the application to deal with invalid URI schemes.
The test brings a Finder window to the front. It's not ideal,
but I have no better idea at the moment. It would be cool if we
can make the test case register itself as handler for a particular
uri scheme, but I have no idea how to do that.
GHashTable optimizes for the "set" case, where key and value are the same.
See g_hash_table_add().
A user cannot see from outside, whether a GHashTable internally is a set
and shares the keys and values array. Adding one key/value pair with
differing key and value, will expand the GHashTable.
In all other cases, the GHashTable API hides this implementation detail
correctly. Except with g_hash_table_steal_extended(), when stealing both the
key and the value.
Fix that. This bug fix is obviously a change in behavior. In practice,
it's unlikely that somebody would notice, because GHashTable contains
opaque pointers and the user must know what the keys/values are and
be aware of their ownership semantics when stealing them. That means,
the change in behavior only affects instances that are internally a set,
of what the user most likely is aware and fills the table with
g_hash_table_add(). Such a user would not steal both the key and
values at the same time. Even if they do, then previously stealing the
value was pointless and would not give them what they wanted. It would
not have meaningfully worked, and since nobody reported a bug about this
yet, it's unlikely somebody noticed.
The more problematic case when the user exhibits the bug is when the
dictionary is unexpected a set internally. Imagine a mapping from numbers
to numbers (e.g. a permutation). If "unexpectedly" the dictionary contains
the identity permutation, steal-extended gives always NULL for the target
number.
The example is far fetched. In practice, it's unlikely that somebody is
gonna notice either way. That is not an argument for fixing anything.
The argument for fixing this, is that the bug breaks the illusion that
the set is only an internal optimization. That is ugly and inconsistent.
Some g++ versions issue an unused-result warning for the g_string_free() macro:
error: ignoring return value of 'gchar* g_string_free_and_steal(GString*)',
declared with attribute warn_unused_result [-Werror=unused-result]
g_string_free(s, TRUE);
This occurs with gcc 6.x / 7.1 / 7.2, and it is fixed in gcc 7.3.
I answered a question on irc about withdrawing notifications, and
when I handed out a link to the GApplication docs, I noticed we
don't have this function name linkified. Fix that.
This fixes the annoations for g_mapped_file_get_contents() which looks
like it might transfer ownership (due to being a char*) but does not as
we're pointing into the mmap() region.
The issue of meson 60 have been resolved for some time now, so we can
just use newer TAP syntax safely.
Revert "gtestutils: Use TAP 13 comments syntax for subtests"
This reverts commit e8725407bcd35c1fa8fed92250edf080d5542b3c.
Closes: #2885
Also start using a more reliable versioning scheme for the fedora images
so that the tag is always vFEDORA_VERSION.IMAGE_VERSION to make it
easier to understand on future updates
Fixes: #3381
Since we run tests in parallel we may end up rewriting the coverage info
while running files acting on the same source files.
The compiler can be smart though, so let's use the proper flag.
Despite this, sometimes we may still end up into negative reports, so
let's ignore them in CI since it's not worth breaking the build because
of these coverage-parsing failures.
