rpm spec - Is it safe to verify the RPM that has just been installed from a %posttrans? -

-

i know non-standard, it's intended overcome short term problem proprietary distribution. because there dependencies unique our deployment systems, have compile libraries %post. because failing here result in corruption rpm database, fail silently or put more accurately, fail :-/

using %verifyscript, able verify if compilation incomplete , exit appropriately. idea can this:

rpm -uvvvh proprietary-dist-1.0-2.i686.rpm rpm --verify proprietary-dist || rpm -uvvvh proprietary-dist-1.0-1.1686.rpm

or this:

rpm -uvvvh proprietary-dist-1.0-2.i686.rpm rpm --verify proprietary-dist || rpm --rollback proprietary-dist

however, making use of %posttrans, figured simplify down to:

rpm -uvvvh proprietary-dist-1.0-2.i686.rpm || rpm --rollback proprietary-dist

it seems unclear documentation whether exiting non-zero %posttrans safe , won't cause rpmdb corruption - well, @ least documentation says shouldn't exit non-zero pre-dates when %pretrans , %posttrans introduced.

i assuming %posttrans run after rpmdb has been updated , committed, in effect, rpm considered installed. bad assumption?

yes correct %posttrans run after rpmdb updated (there no commit in rpm using). meanwhile rpmdb still open, , fsync(2) disabled (for performance).

non-zero %posttrans @ best ignored, otherwise leave "unsuccessful" partial install need "fixed" manually.

ymmv. if rpm breaks using %posttrans, keep pieces.

python - No exponential form of the z-axis in matplotlib-3D-plots -

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 .
