c++ - BSTR memory leak in atldbsch.h - what to do? -

-

i running deleaker application find , fix memory leaks in application. now, finds lot of bstr leaks roots in open()-function of microsoft crestrictions class (atldbsch.h file).

if 1 looks there 1 can notice takes 7 lpctstr parameters, used this:

pvariant = m_pvarrestrictions + 1; . . pvariant->bstrval = ::sysallocstring(t2cole_ex_def(lpszparam1));

this done 7 such parameters (where number 1 increased every time).

the destructor doing

delete[] m_pvarrestrictions;

but bstrs allocated via ::sysallocstring() never freed though via calls ::sysfreestr()

am missing or there leak, , in case how should handled in case?

according https://github.com/dpalma/sge/blob/master/3rdparty/atl/atldbsch.h, m_pvarrestrictions defined atl::ccomvariant *, atl::ccomvariant destructor should cleaning bstr variants (the code correctly setting vt vt_bstr). is, ccomvariant destructor calls ccomvariant::clear calls variantclear.

thus, there should not memory leak here -- code looks correct. issue deleaker having problems detecting pattern.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
