� �mec@skdZddlZddlZddlZejZdZeZ dej fd��YZddd�ZdS(s�A dumb and slow but simple dbm clone. For database spam, spam.dir contains the index (a text file), spam.bak *may* contain a backup of the index (also a text file), while spam.dat contains the data (a binary file). XXX TO DO: - seems to contain a bug when updating... - reclaim free space (currently, space once occupied by deleted or expanded items is never reused) - support concurrent access (currently, if two processes take turns making updates, they can mess up the index) - support efficient access to large databases (currently, the whole index is read when the database is opened, and some updates rewrite the whole index) - support opening for read-only (flag = 'm') i����Nit _DatabasecBs�eZeZeZd�Zd�Zd�ZeZd�Zd�Z d�Z d�Zd�Zd�Z d �Zd �Zd�Zd�ZeZd �Zd�ZeZd�ZRS(cCs�||_|tjd|_|tjd|_|tjd|_d|_yt|jd�}Wn3t k r�t|jd�}|j |j�nX|j�|j�dS(Ntdirtdattbaktrtw( t_modet_ostextsept_dirfilet_datfilet_bakfiletNonet_indext_opentIOErrort_chmodtcloset_update(tselftfilebasenametmodetf((s/usr/lib64/python2.7/dumbdbm.pyt__init__/s cCszi|_yt|j�}Wntk r/nGXx9|D]1}|j�}t|�\}}||j|<q7W|j�dS(N(R RR RtrstriptevalR(RRtlinetkeytpos_and_siz_pair((s/usr/lib64/python2.7/dumbdbm.pyRMs cCs�|jdkrdSy|jj|j�Wn|jjk rCnXy|jj|j|j�Wn|jjk rznX|j|jd�}|j |j�x4|jj �D]#\}}|jd||f�q�W|j�dS(NRs%r, %r ( R RRtunlinkRterrortrenameR RRt iteritemstwriteR(RRRR((s/usr/lib64/python2.7/dumbdbm.pyt_commit]scCsO|j|\}}t|jd�}|j|�|j|�}|j�|S(Ntrb(R RR tseektreadR(RRtpostsizRR((s/usr/lib64/python2.7/dumbdbm.pyt__getitem__vs cCs�t|jd�}|jdd�t|j��}|tdtt}|jd||�|}|j|�|j�|t|�fS(Nsrb+iiit( RR R$tintttellt _BLOCKSIZER!Rtlen(RtvalRR&tnpos((s/usr/lib64/python2.7/dumbdbm.pyt_addval�s cCsFt|jd�}|j|�|j|�|j�|t|�fS(Nsrb+(RR R$R!RR-(RR&R.R((s/usr/lib64/python2.7/dumbdbm.pyt_setval�s cCsT||j|<t|jd�}|j|j�|jd||f�|j�dS(Ntas%r, %r (R RR RR!R(RRRR((s/usr/lib64/python2.7/dumbdbm.pyt_addkey�s cCs�t|�td�ko)t|�kns:td�n||jkre|j||j|��n{|j|\}}|tdt}t|�tdt}||kr�|j||�|j|<n|j|�|j|<dS(Ntskeys and values must be stringsi(ttypet TypeErrorR R3R0R,R-R1(RRR.R&R't oldblockst newblocks((s/usr/lib64/python2.7/dumbdbm.pyt__setitem__�s.cCs|j|=|j�dS(N(R R"(RR((s/usr/lib64/python2.7/dumbdbm.pyt__delitem__�s cCs |jj�S(N(R tkeys(R((s/usr/lib64/python2.7/dumbdbm.pyR;�scCs ||jkS(N(R (RR((s/usr/lib64/python2.7/dumbdbm.pythas_key�scCs ||jkS(N(R (RR((s/usr/lib64/python2.7/dumbdbm.pyt__contains__�scCs |jj�S(N(R titerkeys(R((s/usr/lib64/python2.7/dumbdbm.pyR>�scCs t|j�S(N(R-R (R((s/usr/lib64/python2.7/dumbdbm.pyt__len__�scCs,|j�d|_|_|_|_dS(N(R"RR R R R(R((s/usr/lib64/python2.7/dumbdbm.pyR�s cCs/t|jd�r+|jj||j�ndS(Ntchmod(thasattrRR@R(Rtfile((s/usr/lib64/python2.7/dumbdbm.pyR�s(t__name__t __module__RRRRR"tsyncR(R0R1R3R9R:R;R<R=R>t__iter__R?Rt__del__R(((s/usr/lib64/python2.7/dumbdbm.pyR"s* i�cCsLy tjd�}tj|�Wntk r3nX||@}t||�S(s�Open the database file, filename, and return corresponding object.
