This patch started with the goal of changing the uint level into
a string. The motivation for that was that the numeric constants
would have to be documented (which they weren't) and prevent
us from easily changing the Logger::Level later on.
I did change them once today (see previous commit about reordering the
SHOW level) and really had the problem that a not-restarted
syncevo-dbus-server couldn't talk to a recompiled client.
Using strings avoids that problem.
While changing uint to string I had to make the change twice, once in
an entirely unnecessary new and the pointer definition. Replaced the
shared_ptr with normal members, throughout the code.
Then I wondered about the use of the () operator on these signal
watches. At the point of use it was not obvious what that did. Turns
out that this activates the watch. In contrast to making a remote
function call or emitting a signal, I find the use of the operator
inappropriate for watches. Replaced with an explicit activate()
method.
While looking at the implementation, I found that this operator and
destructors had been duplicated. Instead of fixing it in all copies, I
moved the common code into a SignalWatch<> base template,
parameterized with the type of callback that it deals with.
To support command line in dbus server, it has to avoid stdout and
routing ostream through logging system at the same time sending
signals to dbus clients.
Instead of inheriting from std::stream, here a new class inherits
from std::streambuf, which is to store characters. Re-implement
'overflow' method to control output of command line and redirect
output characters to our logging system.
A new log level 'SHOW' is added in the Logging system. It means
the normal output and the logging system won't add level and prefix
information when putting the information in the logging system.
Redirect outputs of processes started by syncevolution by LogRedirect.
The intention is to get rid of the historic and inconsistent
naming of some classes and their corresponding files:
* EvolutionSyncClient = class derived from Funambol's SyncClient,
* SyncEvolutionConfig = SyncEvolution's config
With the strict 'namespace SyncEvo' and the syncevo/ path prefix for
most header files it is no longer necessary to have "SyncEvolution" or
"Evolution" in the names. This patch thus renames as follows:
EvolutionSyncClient => SyncContext
EvolutionSmartPtr => SmartPtr
SyncEvolutionCmdline => Cmdline
SyncEvolutionConfig => SyncConfig
SyncEvolutionUtil => util
The former EvolutionSyncClient always had a role that went beyond just
running a sync, for example it also provided config access. With the
upcoming server support it also won't be just a client. Thus the new
name "SyncContext".
The 'syncevo/' prefix is used throughout the code now.
removed whenever the prefix made it clear that the file belongs
to SyncEvolution. This helps finding incorrect include paths.
Quotes should be used exclusively for SyncEvolution files which don't
have a specific prefix yet (test.h, config.h) to help identifying
them.
Added syncevo/declarations.h, which has
This is now used for all SyncEvolution source files, except
for the GTK UI, which is written in plain C. In the library
it helps to avoid name clashes.
The reason for using defines instead of spelling out "namespace SyncEvo"
is twofold:
1. if that should ever become necessary, it is easier to
rename the namespace via configure options by changing
the define
2. editors don't indent the whole file content
