annotate src/event/modules/ngx_rtsig_module.c @ 559:c1f965ef9718 release-0.3.1
nginx-0.3.1-RELEASE import
*) Bugfix: the segmentation fault occurred when the signal queue
overflowed if the "rtsig" method was used; the bug had appeared in
0.2.0.
*) Change: correct handling of the "\\", "\"", "\'", and "\$" pairs in
SSI.
