# HG changeset patch # User FUJIWARA Katsunori <foozy@lares.dti.ne.jp> # Date 1449617333 -32400 # Wed Dec 09 08:28:53 2015 +0900 # Node ID cec0b4d331b1fca867fcf4b567c69e1718576fe9 # Parent f67cce78a8dcd70a645267cfec27f45b713d6456 censor: make censor acquire locks before processing Before this patch, "hg censor" executes below: - without acquisition of wlock, examine whether the working directory refers the revision of the file to be censored or not - without acquisition of store lock (slock), replace existing filelog of file to be censored with censored one, Replacement consists of steps below, and it is assumed that the destination filelog at (1) isn't changed before renaming at (3). 1. read existing filelog in 2. write filelog entries (both censored and not) into temporary file 3. rename from temporary file to existing filelog to be censored It may cause unintentional result, if another command runs parallelly (see also issue4368). This patch makes "hg censor" acquire wlock and slock before processing.
