Moving all of the error-handling to it for better clarity and
simplicity. Drop the unnecessary stat call, open will fail with
EEXIST if there's already a lock file. Provide specific messages
for file system failures.
This was an effort of somewhat dubious value to detect if a process
on another ocmputer had a hsrd-link to a lockfile on an NFS share.
NFS is rarely used now and SMB doesn't support hard links so this check
adds complexity with no real value.
m_lockfd is not initialised. If the file is locked then it will not be set
before session_end and close() will be called on an uninitialised int.
Initialise it to -1 in the class definition.
Consistently use -1 instead of "< 0" or "< 1" as the definition of invalid.
Always set it to -1 after closing it.
Move all of the #include <glib> to before the extern "C" blocks
so that the include guards will protect against headers inside
the extern "C" block also including glib.h.
to mysql database.
It's more general, any save-as to a different backend type, i.e.
xml->sql or sql->xml, left the previous book locked.
Ensure that the session is ended and the book unlocked in the
backend's destructor. This also fixes a memory leak in the SQL
backend because the GncSqlConnection wasn't being deleted.
Price Database dropping user:price-editor entries.
A wider problem: QofInstance was unmarking itself dirty as long as the
backend raised an error and unconditionally marking itself non-infant.
This matters because the SQL backend depends on infant status to decide
whether to do an insert or update query; either will fail if the infant
status is wrong.
The price editor dialog clones a price having only its commodity set and
GncSqlPriceBackend declines to save if the currency isn't set. Since the
instance marked itself non-infant even though it wasn't saved subsequent
commits tried to use an update query and since the price wasn't in the
table that inevitably failed.
Requiring that QofBackend::commit should doing the marking-clean
required implementing it in the backends where it wasn't already.
For clarity. In so doing found the backend behavior a bit inconsistent
so it's modified to do what the enum values indicate.
In the course of changing the various calls I found some implementation
errors in the back end and corrected them.
It's more descriptive and less likely to be confused with the book:id value
in XML files that is the book's GUID.
Also changed the QofSessionImpl::begin new_uri parameter from std::string to
const char*. There's no point in allocating a string just to call
new_uri.c_str() all over the place.
It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)
This is the first step in restructuring the code. It will need much
more fine tuning later on.
