Check that current state is State_Idle in wxWebRequest itself only once
instead of doing it in 2 (out of 3) wxWebRequestImpl implementations.
Also assert if this is not the case instead of silently doing nothing
which would surely be more difficult to debug.
Don't duplicate calls to ::FormatMessage(), which is difficult to use
correctly, in wxCrashReport and wxWebRequestWinHTTP, but just reuse the
same code that was already present in wxSysErrorMsgStr() after
refactoring it into a reusable function allowing to specify the module
name to use for the error code lookup (before falling back to
interpreting it as system error code).
This fixes not trimming the trailing "\r\n" from the string in the other
places (wxWinHTTPErrorToString() had code to do it, but it was wrong,
while wxCrashContext::GetExceptionString() didn't do it at all) and
avoids duplication.
Instead of doing it the other way round, as it has several advantages:
1. wxSysErrorMsgStr() is not limited by the static buffer size any
longer, i.e. doesn't truncate errors even longer than 1KiB.
2. Code is much simpler and more obviously correct.
3. We avoid an extra and absolutely unnecessary buffer copy.
No real changes.
Just micro cleanup: there doesn't seem to be any need to show which
function we're in as FormatMessage() is only called from a single place
anyhow, so shorten and simplify the code.
Rename Init() to Open() as we need this method to return bool to
indicate its success in order to avoid using non-initialized handle
later. Init() is also reserved, by convention, for the common part of
all class ctors in wx code.
Remove m_initialized entirely, it doesn't seem to be obviously better to
cache the failure to create a session than to retry doing it every time
(in fact, it would seem to be worse) and not having it is simpler.
This commit is best viewed ignoring white space.
A cancelled request is not supposed to end up in the "failed" state, but
it did, resulting in showing an error in the webrequest sample after
pressing on the "Cancel" button, which was clearly unwanted.
When cancelling a request it was possible for it to be deleted while it
was still used from another thread.
Fix this and make the code much more obviously correct by simply
"locking" the request until the event generated by it is processed: now
IncRef() and DecRef() calls are always balanced as they're called from
ctor and dtor of StateEventProcessor helper only.
Shared ownership semantics again seems inappropriate here as we're not
actually sharing the pointers here, so just use raw pointers instead
(with C++11 we could use std::unique_ptr<>, but this is impossible with
our own map and scoped pointer implementations).
No real changes.
Using shared pointer seems to be ill-advised here, the stream shouldn't
be shared as it's going to be used by wxWebRequest itself and can't be
used by the application code in parallel, so the ownership transfer
semantics is more appropriate.
We could take a wxScopedPtr<> instead, but wx API takes ownership of raw
pointers everywhere else, so do it here too.
Incidentally fix a bug with calling IsOk() on a possibly null pointer.
Don't force the application code to deal with wxObjectDataPtr<> or,
worse, calling {Inc,Dec}Ref() manually by hiding it inside the wx
objects themselves and giving the value-like semantics to them.
There should be no real changes in the behaviour, but the API does
change significantly. Notably, wxWebRequest is not a wxEvtHandler itself
any longer, as this would be incompatible with the value semantics, and
an event handler needs to be specified when creating it, so that it
could be notified about the request state changes.
Having wxWebSessionFactory part of the public API implies keeping
compatibility with the possible ways of implementing it which is too
restrictive for no good reason, so move this class to the private header
and don't document it nor wxWebSession::RegisterFactory() (which is now
private).
Using anything else is not recommended by libcurl documentation and it's
not clear why would we need it, so just follow the official advice and
pass CURL_GLOBAL_ALL.
This is unnecessary, it can be protected and we can initialize
wxWebRequest::m_headers directly in its ctor instead of using this
function (which also simplifies code and makes it impossible to forget
to do this).
Use BeforeFirst() when we only need to find the first colon instead of
wxSplit().
No real changes (except for pathological case when there is no colon at
all, which wasn't handled correctly by the original code and still
isn't, but in a slightly different way).
They're not necessary to use this class and we may consider exporting
them later, possibly with a better API and more tests, if really needed.
Also do change their API slightly by leaving only a single function and
returning the value instead of using an out parameter for it to make it
simpler to use.
Define wxWebSession::ms_defaultSession and ms_factoryMap in the
implementation file to avoid having to make the otherwise unnecessary
wxStringWebSessionFactoryMap type public.
No real changes.
The former can be called from the derived class ctors while the latter
only needs to be called from wxWebRequest itself, so just make it a
friend: this is not ideal, but still better than leaving this public and
simpler than any alternatives.
It doesn't make much sense to specify the conversion here, it would
ideally be taken from the response Content-Type header itself and
currently is just assumed to be UTF-8 anyhow.
Also implement fallback to Latin-1 to avoid losing the data entirely if
it's not in UTF-8.
Check that the stream is valid, if specified at all, and return false if
it isn't -- or if no size was specified and determining stream size
failed.
Check for SetData() success in the test to provide better diagnostics in
case the file it uses is not found (as is the case when running the test
from another directory, for example).
Also pass wxSharedPtr<> by const reference instead of by value to avoid
unnecessary copies.
Calling SystemParametersInfoForDpi() with LOGFONTA parameter corrupted
the stack because this function only accepts LOGFONTW, i.e. it wrote
twice as much data into the provided buffer as the caller expected.
This could be fixed by allocating a temporary wide buffer and converting
back, but this doesn't seem to be worth it, so just disable the use of
the DPI-specific function in the ANSI build.
Closes#19002.
This results in various problems, including both the problems with
handling keyboard input (see #16840) and, even less expectedly,
graphical issues with flickering (see #18462).
Fixing or working around these issues doesn't seem to be easily
possible, but we can at least warn people about the problem.
Closes https://github.com/wxWidgets/wxWidgets/pull/2138
Add the #pragma to link with shlwapi in the same object file which uses
this function, as even though the same pragma was already present in
other files, they could be completely discarded by the linker resulting
in link errors about unresolved StrCmpLogicalW() later.
Also move the MinGW-specific function declaration to the top of the
file, near the inclusion of the header which would normally declare it.
The rect offset was correctly changed in 04a7a3f150 (Fix drawing outside
of the splitter sash under macOS, 2020-12-05), but its size was not. Fix
it too now.
See #18861.
As we don't use any special value for the inactive caption background,
use the same value as for normal caption text for inactive caption text
too.
This is almost certainly not ideal, but at least allows the tab labels
to be readable.
Closes#18988.
This should have been done together with the changes of 41410610ef
(Don't force wxPU_CONTAINS_CONTROLS on wxPopupTransientWindow,
2020-07-10) as without this style controls inside wxComboPopup couldn't
accept focus any more, which broke the previously working code.
There is no need to check if the control is a wxComboBox if it turns out
to already be a wxTextCtrl.
No real changes, just a micro-optimization and simplification.
